Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a relay. Background Art

[0002] A relay typically includes a contact portion, which includes a static contact and a moving contact assembly. The static contact is provided with a static contact point, and the moving contact assembly generally includes a moving contact and an elastic member. One end of the moving contact is fixed, while the other end is swingable and provided with a moving contact point. Existing elastic members are generally integrally formed with or riveted to the swinging end of the moving contact. In the prior art, the elastic member extends along the length of the moving contact and is provided with a deformable portion that is inclined relative to the moving contact. The elastic member is used to apply pressure to the moving contact, thereby forming a contact pressure on the moving contact that can close with the static contact. However, due to factors such as limited space and the fact that the moving contact size should not be designed too small, the elastic member cannot be made larger, the contact pressure it can provide is small, and the service life of the elastic member is short, resulting in poor connection reliability between the moving contact and the static contact.

[0032] Based on Technical Solution Twenty-Seven, there is also provided Technical Solution Twenty-Eight. In Technical Solution Twenty-Eight and its related embodiments, the bending portion includes a first bending portion and a second bending portion with opposite bending directions.

[0033] From the above description of the present invention and its preferred embodiments, it can be seen that, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0034] The applicant has learned through continuous observation, experimentation and research that the reasons for the technical problem of "the elastic member is used to apply pressure to the moving contact so that the contact pressure formed on the moving contact that can close with the static contact is small and the life of the elastic member is short" in the existing technical solution are: "First, since the area occupied by the moving contact on the moving contact is usually large, the width reserved for the elastic member in the width direction of the moving contact is small, and the elastic member cannot obtain a larger width or a larger elastic force. Therefore, the contact pressure that can be provided to the moving contact is also limited. If the width of the moving contact is increased to make the elastic member wider, the required consumables of the moving contact will increase, which is not conducive to controlling production costs and occupies more space; second, in order to To minimize volume and cost, the two opposing inner walls of the base along the extension direction of the moving contact are typically positioned near each end of the moving contact. This limits the length of the elastic member to a limited extent along the length of the moving contact. To drive the free end of the deformable portion to swing a specific angle, the deformable portion of the elastic member must tilt at a larger angle. This large tilt angle can easily lead to greater stress at the root of the deformable portion, causing mechanical fatigue and shortening the service life of the elastic member. To address this issue, if the elastic member is designed to be longer, thereby increasing the overall length of the moving contact assembly, the spacing between the two opposing inner walls of the base must be increased accordingly, which in turn increases the size of the relay.

[0035] In technical solution 1 and its related embodiments, the elastic portion extends along the Z-axis, which intersects the extension direction of the moving contact, effectively utilizing the space in the Z-axis direction. This allows the width of the elastic portion to be widened and the length of the elastic portion to be extended as much as possible without changing the size of the moving contact, the width of the moving contact, and the overall length of the moving contact assembly. Widening the width of the elastic portion enables the elastic member assembly to provide greater contact pressure to the moving contact, while extending the length of the elastic portion eliminates the need for setting an excessively large inclination angle for the elastic member, thereby reducing the stress on the elastic member, avoiding fatigue failure, and increasing its service life. Based on this, this solution and its related embodiments can enable the moving contact to obtain greater contact pressure even in limited space, thereby increasing the service life of the elastic member and thereby improving the connection reliability of the moving and static contacts. The second end of the elastic portion is fixedly connected to or abuts the swinging end of the moving contact. Compared to when the elastic portion is fixedly connected to or abuts other positions on the moving contact, the elastic member assembly applies greater contact pressure to the moving and static contacts to close the moving contact. In addition, in the present solution and its related embodiments, during the driving process of the driving member, the contact position between the driving member and the elastic part will not change or change slightly along the Z-axis direction, the elastic coefficient of the elastic part remains stable or relatively stable, and the elastic force changes linearly without sudden changes. The final contact pressure range is controllable, so that the required magnetic driving force can be easily controlled and the dynamic contact can be reliably driven to contact or move away from the static contact.

[0036] In technical solution two and its related embodiments, the Z-axis direction is perpendicular to the extension direction of the dynamic contact, which further reduces the space occupied by the dynamic contact in the Z-axis direction, reduces the influence of the elastic member group on the size of the dynamic contact and the size occupied along the extension direction of the dynamic contact, and makes the elastic force provided by the elastic member group toward the static contact greater.

[0037] In technical solution three and its related embodiments, the position where the second end of the elastic part is fixedly connected or in contact with the swinging end of the dynamic contact is farther away from the fixed end than the contact position between the dynamic contact and the static contact, so that the torque exerted by the elastic part on the dynamic contact is greater. When the elastic part is pressurized by the driving part, the contact stability between the dynamic contact and the static contact is higher.

[0038] In technical solution 4 and its related embodiments, the fixed portion is fixedly connected to the swinging end of the movable contact and is integrally connected to the second end of the elastic portion. Compared with directly molding the elastic portion on the movable contact, the molding of the movable contact is less difficult.

[0039] In technical solution five and its related embodiments, the fixed portion is fixedly connected to the moving contact at the position where the moving contact is located, and the contact pressure applied by the elastic portion to the moving contact is greater than that at other positions.

[0040] In technical solution six and its related embodiments, moving contacts are provided on both sides of the swinging end of the moving contact, which are opposite to each other, corresponding to the static contacts of the static contact, which is conducive to the contact between the moving contact and different static contacts, and is conducive to the formation of a switching circuit. There are two elastic parts, which are respectively provided on both sides of the moving contact, and are used to provide contact reaction force to the moving contacts on both sides of the moving contact, so that the moving contacts on both sides of the swinging end are subjected to the contact pressure of the elastic part, thereby ensuring the stable closure of the moving contacts on both sides and the corresponding static contacts.

[0041] In technical solution seven and its related embodiments, the two elastic parts are symmetrically arranged about the swing end along their elastic deformation direction. Compared with the staggered arrangement of the two elastic parts along the extension direction of the moving contact, the driving forces applied by the two elastic parts to the moving contact are closer in magnitude, thereby ensuring that the moving contacts on each side of the moving contact have greater contact pressure.

[0042] In Technical Solution 8 and its related embodiments, each static contact is provided with at least two static contacts arranged along the Z-axis. Correspondingly, the swinging ends of the movable contact are divided into multiple paths corresponding to each of the static contacts, each with a movable contact. When a movable contact contacts a corresponding static contact, the current flowing through the movable contact is split into multiple paths, thereby reducing the resistance of the movable contact and improving its overall current-carrying capacity. The projections of the static contacts on a plane perpendicular to the Z-axis completely overlap, compared to the staggered Y-axis positions of the static contacts of each static contact. This reduces the space occupied by the contact portion in the Y-axis. The elastic portion is an elastic arm, and the fixed portion is a first connecting wall extending along the Z-axis. The elastic arm and the first connecting wall are arranged along the extension direction of the movable contact. The first connecting wall is fixedly connected to the swinging ends of each movable spring. The second end of the elastic arm is adapted to drive each movable spring, allowing a single elastic arm to apply contact pressure to multiple movable contacts on the other side of the movable contact. This results in a simple structure and low cost.

[0043] In technical solution nine and its related embodiments, each static contact is provided with at least two static contacts arranged along the Z-axis. Correspondingly, the swinging end of the dynamic contact is divided into multiple static contacts corresponding to each other, and a dynamic contact is provided for each of them. However, when the dynamic contact collides with the corresponding static contact, the current flowing through the dynamic contact is divided into multiple paths, thereby reducing the resistance of the dynamic contact and improving the overall current carrying capacity. The projections of the static contacts on the projection plane perpendicular to the Z-axis completely overlap, and compared with the staggered Y-axis positions of the static contacts of each static contact, the contact portion occupies a smaller space in the Y-axis direction. Each elastic portion is provided with an elastic arm equal to the number of the dynamic springs. The elastic arms are arranged at intervals along the extension direction of the dynamic springs and are suitable for driving each dynamic spring respectively, ensuring that the dynamic contact on each dynamic spring has a large contact pressure, thereby ensuring the stable closure of each dynamic contact with the corresponding static contact.

[0044] In technical solution ten and its related embodiments, each elastic member is further provided with a second connecting wall corresponding to each elastic arm and connected to the second end of the elastic arm. Each second connecting wall is respectively fixed to each movable spring piece, which is conducive to ensuring that the elastic arms do not interfere with each other. Compared with the solution in which each elastic arm is separately formed on each movable spring piece, the movable spring piece is easier to process and form.

[0045] In the eleventh technical solution and its related embodiments, in each elastic portion, each elastic arm extends from the corresponding dynamic spring piece along the Z-axis toward one side of the driving member. In this way, each elastic arm forms a clearance with the corresponding dynamic spring piece along the Z-axis, thereby enabling better elastic deformation. The shape and size of each elastic arm are designed to be consistent, which is conducive to providing more consistent contact pressure to each dynamic spring piece, ensuring the consistency of the operating parameters of each dynamic spring piece. Along the Z-axis, the elastic arm corresponding to the dynamic spring piece farther away from the driving member is farther from the fixed end of the dynamic contact piece. Therefore, the elastic arm also avoids other dynamic spring pieces during the process of extending along the Z-axis, further ensuring that each elastic arm has good elastic deformation ability. It is worth noting that in this solution and its related embodiments, by changing the position of the side edge of each dynamic spring piece from which the elastic arm extends, the second end of each elastic arm in the same elastic portion can be arranged flush along the Z-axis or staggered. The staggered arrangement ensures that the dynamic spring piece has a uniform width distribution structure, which can avoid increasing copper loss.

[0046] In technical solution 12 and its related embodiments, the first ends of the elastic arms of each elastic part are connected as one, which is conducive to facilitating the molding of each elastic part.

[0047] In technical solution thirteen and its related embodiments, the elastic part group is also provided with a fixing part; the fixing part is connected to the first end of the elastic part as a whole and is used to be fixed to the driving part; the second end of the elastic part is in contact with the moving contact part, which is beneficial to the assembly of the elastic part and the moving contact part, especially when the moving contact part is composed of multiple elastic sheets stacked together, the elastic part only needs to contact one side of the moving contact part.

[0048] In technical solution fourteen and its related embodiments, moving contacts are provided on both sides of the swinging end of the moving contact, which correspond to the static contacts of the static contact, which is conducive to the contact between the moving contact and different static contacts, and is conducive to the formation of a switching circuit; there are two elastic parts, and the two elastic parts are respectively provided on both sides of the moving contact, which are away from each other, and are used to provide contact reaction force to the moving contacts on both sides of the moving contact, so that the moving contacts on both sides of the swinging end are subjected to the contact pressure of the elastic part, ensuring the stable closure of the moving contacts on both sides and the corresponding static contacts.

[0049] In technical solution fifteen and its related embodiments, the two elastic parts are symmetrically arranged about the swing end along their elastic deformation direction. Compared with the staggered arrangement of the two elastic parts along the extension direction of the moving contact, the driving forces applied by the two elastic parts to the moving contact are closer in magnitude, thereby ensuring that the moving contacts on each side of the moving contact have greater contact pressure.

[0050] In technical solution 16 and its related embodiments, each static contact is provided with at least two static contacts arranged along the Z-axis. Correspondingly, the swinging end of the dynamic contact is divided into multiple static contacts corresponding to each static contact, and a dynamic contact is provided for each of them. However, when the dynamic contact contacts the corresponding static contact, the current flowing through the dynamic contact is divided into multiple paths, thereby reducing the resistance of the dynamic contact and improving the overall current carrying capacity. The projections of the static contacts on the projection plane perpendicular to the Z-axis completely overlap, and compared to the staggered Y-axis positions of the static contacts of each static contact, the contact portion occupies a smaller space in the Y-axis direction. The provision of multiple elastic members ensures that each moving spring of each moving contact is driven by an elastic member. The two elastic arms of the elastic member clamp the two sides of the moving spring, simplifying assembly and ensuring that each moving contact of each moving contact has a high contact pressure. The connection portions are arranged at intervals along the extension direction of the moving contact, thus avoiding interference between the elastic members.

[0051] In technical solution seventeen and its related embodiments, in each elastic part, the elastic arms at least partially overlap on the projection surface perpendicular to the elastic deformation direction. Compared with the solution in which the elastic arms are arranged along the extension direction of the dynamic spring, it is beneficial for the elastic members to apply greater contact pressure to the corresponding dynamic spring.

[0052] In technical solution eighteen and its related embodiments, the connecting portion of the second elastic member includes a fourth connecting wall extending along the X-axis direction and a fifth connecting wall extending obliquely from the fourth connecting wall on both sides of the X-axis direction relative to the Z-axis direction and the Y-axis direction. The elastic arm of the second elastic member is connected as a whole with the fifth connecting wall on the same side, which is conducive to avoiding interference between the elastic members.

[0053] In technical solution nineteen and its related embodiments, during installation, the first elastic member is first inserted into the first through hole from the second opening until the third connecting wall abuts the first supporting wall and the two elastic arms are respectively inserted into the gap between the first supporting wall and the hole wall of the first through hole, and then the second elastic member is inserted into the first through hole from the second opening until the fourth connecting wall abuts the second supporting wall and the two fifth connecting walls and the two elastic arms are respectively inserted into the gap between the second supporting wall and the hole wall of the first through hole, and then the pressure plate or the pressure plate is pressed against the third connecting wall and the fourth connecting wall, and the two elastic arms of the first elastic member are located between the two elastic arms of the second elastic member along the X-axis direction, so that the first elastic member and the second elastic member are limited to the driving part in the X-axis direction, the Y-axis direction and the Z-axis direction, and it is ensured that each moving contact of each moving contact member has a higher contact pressure.

[0054] In technical solution 20 and its preferred embodiment, the swinging end of the first movable spring is also located inside the driving part, which is beneficial to reducing the length of the elastic part along the Z-axis direction, reducing the length of the relay in the Z-axis direction, and ensuring that the driving part abuts the first elastic part to elastically deform the elastic arm.

[0055] In technical solution twenty-one and its related embodiments, the armature assembly rotates around a rotation axis extending along the Z-axis direction and forms a driving member, which has a simple and practical structure.

[0056] In technical solution twenty-two and its related embodiments, the first end of the elastic part is accommodated in the driving part. Compared with the solution in which the elastic part is outside the driving part, the connection between the elastic part and the driving part is more stable and occupies less space in the X-axis direction.

[0057] In Technical Solution Twenty-three and its related embodiments, when the first end of the elastic part contacts the moving contact, the second end of the elastic part is fixed relative to the driving part along the Z-axis direction, thereby avoiding the movement of the elastic part along the Z-axis direction. The resulting change in the elastic force provided by the elastic part to the swinging end toward the static contact improves the connection reliability between the dynamic contact and the static contact.

[0058] In technical solution twenty-four and its related embodiments, the fixed ends of the two moving contacts are respectively fixed to the two static contacts located on the diagonals of the quadrilateral formed by the four static contacts, and the swinging ends of the two moving contacts are both located between the two groups of static contacts along the X-axis direction, and are respectively suitable for moving in opposite directions until they come into contact with the static contacts. Therefore, by closing the two moving contacts on the swinging ends with different static contacts, the switching of different static contacts in series and parallel can be achieved.

[0059] In Technical Solution 25 and its related embodiments, when the movable contact at the first swing end closes with the fourth static contact, the movable contact at the second swing end closes with the second static contact, the second static contact and the third static contact are connected in series via the first movable contact and the second movable contact, and the first movable contact and the second movable contact are connected in parallel. When the movable contact at the first swing end closes with the first static contact, the movable contact at the second swing end closes with the third static contact, the first static contact and the second static contact are connected in series via the first movable contact, and the third static contact and the fourth static contact are connected in series via the first movable contact. The four static contacts are located at the four corners of a rectangle, and compared to a parallelogram or other quadrilateral structure, the contact portion occupies less space along the Y-axis.

[0060] In technical solution twenty-six and its related embodiments, driving parts are respectively provided at both ends of the armature assembly along the Y-axis direction. The two driving parts are respectively used to drive the elastic part groups of the two moving contact groups, and are respectively suitable for accommodating the first ends of the elastic parts. The structure is simple to use, and the first end of the elastic part is accommodated in the driving part. Compared with the solution in which the elastic part is outside the driving part, the connection between the elastic part and the driving part is more stable, and the space occupied in the X-axis direction is smaller.

[0061] In technical solution twenty-seven and its preferred embodiment, the moving contact is provided with a bending portion protruding relative to the extension direction of the moving contact. The setting of the bending portion can absorb the movement of the moving contact in the Y-axis direction when the moving contact and the static contact are closed or disconnected along the X-axis direction, thereby avoiding the moving contact and the static contact from being staggered along the Y-axis direction.

[0062] In technical solution 28 and its preferred embodiment, the bent portion includes at least two first and second bent portions with opposite bending directions, further preventing the movable contact and the stationary contact from being misaligned along the Y-axis. Furthermore, positioning one of the bent portions near the fixed end of the movable contact facilitates determining the deformation fulcrum. BRIEF DESCRIPTION OF THE DRAWINGS

[0130] A relay is used to receive electrical signals to control the on / off state of an external circuit. Specifically, the relay in this embodiment is a magnetic latching relay, which controls the on / off state of an external circuit by receiving pulsed electrical signals. In this embodiment, the pulsed electrical signals can be divided into a first pulsed electrical signal and a second pulsed electrical signal. The first pulsed electrical signal and the second pulsed electrical signal are used to control the switching or on / off state of the external circuit, respectively.

[0131] See also Figure 1-2 , Figure 1-2 The structure of the relay in this embodiment is shown in FIG. Figure 1 As shown, the relay includes an accommodating member 10 , a magnetic circuit portion 100 , a contact portion 200 and an auxiliary contact portion 300 .

[0132] The accommodating member 10 includes a housing 11 , a first cover 12 , a second cover 13 and a fixing frame 14 .

[0133] Figure 3-6 The structure of the housing 11 in this embodiment is shown in FIG. Figure 3-6 The first end and the second end of the shell 11 along the Z-axis direction are both open, wherein the first end is the upper end of the shell 11, and the second end is the lower end of the shell 11. The shell 11 is provided with a first side wall 111 and a second side wall 112 parallel to and opposite to each other along the X-axis direction, wherein a first partition plate 113 perpendicular to the Z-axis direction and a first isolation plate 114 perpendicular to the X-axis direction are provided therein, the first isolation plate 114 and the first partition plate 113 cooperate with the second side wall 112 to form a first groove opening toward the second end, and a connecting hole 1131 is respectively provided at both ends of the first partition plate 113 along the Y-axis direction; the inner cavity of the first groove is a rectangular parallelepiped structure, and four matching grooves 117 extending along the Z-axis direction are respectively formed at its four vertex corners. Two mating grooves 117, which are arranged in opposite directions along the X-axis, are provided with mutually opposing clearance openings 118. Two communication holes 1131 are located between the four mating grooves 117 along the X-axis. Two mounting seats 115, spaced apart along the Y-axis, and a reinforcing wall 116, perpendicular to the Z-axis, are provided within the housing 11, near the first sidewall 111. The mounting seats 115 are provided with mounting grooves opening toward the second end. A first opening 1151 is provided on the opposing side of the two mounting seats 115. The reinforcing wall 116 is provided with clearance openings 1161, which are respectively connected to the two first openings 1151. The reinforcing wall 116 is also provided with a second opening 1162, which is located near the first sidewall 111. The housing 11 also includes a fixing seat 119, which is integrally connected to the reinforcing wall 116 and the first sidewall 111.

[0134] See also Figure 1-2 The first cover 12 is fixedly connected to the outer wall of the first end of the shell 11. In this embodiment, the first cover 12 is first clamped to the outer ends of the first side wall 111 and the second side wall 112 and then fixed by glue.

[0135] The second cover 13 is fixedly connected to the second end of the housing 11. In this embodiment, the second cover 13 and the second end of the housing 11 are first clamped and then fixed by glue. Figure 1 The second cover 13 includes a bottom wall 131 perpendicular to the Z-axis direction and a second isolation plate 132 protruding from the inner surface of the bottom wall 131 along the Z-axis direction. Figure 7 , Figure 7 The bottom view of the relay is shown. The bottom wall 131 is provided with a plurality of through holes for the connection terminal 02, the signal terminal 01 and the lead terminal 03 described below to pass through and extend out. Figure 7 Holes 1, 2, 3, and 4 are for signal terminals 01 of coil assembly 20 to pass through, holes 5, 6, 7, and 8 are for connection terminals 02 of contact portion 200 to pass through, and holes 9 and 10 are for lead terminals 03 of auxiliary contact portion 300 to pass through. Bottom wall 131 cooperates with the first groove of housing 11 to form contact chamber 001 for accommodating contact portion 200 and cooperates with housing 11 to limit displacement of coil assembly 20 along the Z-axis. A support surface 1311 is protruded from the bottom wall 131, and the support surface 1311 is suitable for abutting against the end surface of the second end of the shell 11 or the step surface perpendicular to the Z-axis direction formed in the shell 11. The second isolation plate 132 protrudes from the support surface 1311 and forms a second groove on the first side wall 111 of the opening. When the second cover body 13 is fixed to the shell 11, the second isolation plate 132 abuts against the first isolation plate 114 along the X-axis direction and against the inner surfaces of the two side walls opposite to the shell 11 along the Y-axis, so that the second isolation plate 132 abuts against the inner wall of the shell 11 along the X-axis direction and the Y-axis direction.

[0136] See also Figure 1 The fixing bracket 14 is fixedly attached to the housing 11. Specifically, it is supported within the housing 11 by being positionally connected to the housing 11 along the X-axis and Y-axis directions. Subsequently, when the first cover 12 is fixedly attached to the outer wall of the first end of the housing 11, it is positionally engaged with the housing 11 and the first cover 12 along the Z-axis direction. The fixing bracket 14 and the first partition 113 are opposed to each other and extend toward each other to form a protruding shaft that rotatably engages with the rotation hole 331 of the armature assembly 30 described below. The fixing bracket 14 is further provided with a position-limiting portion 141 and an abutting portion 142 on a side near the first sidewall 111.

[0137] See also Figure 8 , Figure 8 The magnetic circuit portion 100 is shown as a schematic diagram of the magnetic circuit portion 100 installed in the container 10, and the magnetic circuit portion 100 includes a coil assembly 20 (refer to Figure 9 ) and armature assembly 30.

[0138] See also Figure 9-10 , Figure 9-10The schematic diagram of the coil assembly 20 is shown. The coil assembly 20 includes a coil frame 21, a coil winding 22, an iron core 23 and two yokes 24. The coil frame 21 extends along the Y-axis direction and is provided with a center hole extending along the Y-axis direction. The coil frame 21 is provided with retaining walls at both ends along the Y-axis direction. The coil winding 22 is wound on the coil frame 21 and is located between the two retaining walls. Therefore, the axis of the coil winding 22 also extends along the Y-axis direction. The coil winding 22 is connected to the signal terminal 01. The signal terminal 01 is fixed to the retaining wall of the coil frame 21 and passes through the bottom wall 131 along the Z-axis direction and extends out from the bottom wall 131 (see Figure 2 and Figure 7 ). The iron core 23 extends along the Y-axis direction and is inserted into the center hole of the coil frame 21. The two yokes 24 are respectively fixed to the two ends of the iron core 23, and the ends of the two yokes 24 away from the iron core 23 respectively form magnetic drive ends 242. The two magnetic drive ends 242 are arranged along the Y-axis direction, and the two magnetic drive ends 242 are respectively a first magnetic drive end 243 and a second magnetic drive end 244. In this embodiment, each yoke 24 is provided with a connecting section 241 extending along the Z-axis direction and perpendicular to the Y-axis direction and a magnetic drive end 242 perpendicular to the X-axis direction. The two connecting sections 241 are tightly fitted with the retaining walls at both ends of the coil frame 21, and the magnetic drive end 242 is connected to one side of the connecting section 241 along the X-axis direction and the length along the Z-axis direction is less than the length of the connecting section 241 along the Z-axis direction, so that the two magnetic drive ends 242 and the coil winding 22 are arranged along the Z-axis direction. Figure 10 In the projection plane perpendicular to the Z-axis direction, the projection of the coil winding 22 covers the projection of the magnetic drive end 242. The end of the connecting section 241 close to the magnetic drive end 242 is suitable for being inserted into the mounting groove described above, and the magnetic drive end 242 is suitable for extending from the first opening 3412, so that the two mounting seats 115 of the shell 11 can limit the yoke 24 in the X-axis direction and the Y-axis direction. Of course, in this embodiment, in addition to the mounting seat 115, the coil frame 21 and the yoke 24 are also provided with other limiting structures that are tightly plugged into the accommodating part 10 along the Z-axis direction. The limiting structure is preferably also connected to the accommodating part 10 in the form of glue, so that the coil assembly 20 is fixed to the accommodating part 10.

[0139] See also Figure 11-17 , Figure 11-17 The structure of the armature assembly 30 is shown. The armature assembly 30 is driven by the coil assembly 20 to rotate about a rotation axis extending along the Z-axis. In this embodiment, the armature assembly 30 rotates between a first position and a second position. The rotation axis of the armature assembly 30 and the axis of the coil winding 22 are arranged along the X-axis.

[0140] like Figure 11-17 As shown, in this embodiment, the armature assembly 30 includes a permanent magnet 31 ( Figure 22), two armatures 32 and an insulating member 33, the permanent magnet member 31 is formed of magnetized magnetic steel. In other embodiments, the permanent magnet member 31 can also be made of other permanent magnetic materials, such as neodymium iron boron permanent magnets. The permanent magnet member 31 has two magnetic poles with fixed polarity, and the polarities of the two magnetic poles are opposite. The two armatures 32 are respectively fixed to the two magnetic poles of the permanent magnet member 31, and each armature 32 is respectively provided with two suction parts suitable for being attracted to the magnetic drive end 242. When the magnetic circuit part 100 is in the magnetic holding state, the two armatures 32 respectively have a suction part that attracts the corresponding magnetic drive end 242 to form a closed magnetic circuit passing through the two magnetic drive ends 242. In this embodiment, the two armatures 32 are respectively a first armature 32 and a second armature 32. The two ends of the first armature 32 in the length direction are respectively provided with two first suction parts 321; the two ends of the second armature 32 in the length direction are respectively provided with two second suction parts 322.

[0141] The insulating part 33 is fixedly connected to the permanent magnet part 31 and the two armatures 32. For example, the insulating part 33 can be an injection molded part. The insulating part 33 wraps the two armatures 32 and the permanent magnet part 31 to form a whole. Both ends of the first armature 32 and the second armature 32 are located outside the insulating part 33.

[0142] A rotation hole 331 extending along the Z-axis is provided on the side of the insulating member 33 away from the magnetic drive end 242. This rotation hole 331 can rotatably engage with the protruding shafts on the fixing frame 14 and the first partition 113, enabling the armature assembly 30 to rotatably engage with the first partition 113 and the fixing frame 14. Driving portions 34 extending along the Z-axis and adapted to extend through the two connecting holes 1131 are also provided at both ends of the insulating member 33 along the length. The two driving portions 34 are also located at opposite ends of the armature assembly 30 along the Y-axis. An auxiliary driving portion 35 is provided on the side of the insulating member 33 away from the rotation axis. The auxiliary driving portion 35 is offset from the center of the armature assembly 30 along the Y-axis and located in the middle of the armature assembly 30 along the Z-axis. The driving portion 34 and the rotation axis of the armature assembly 30 are arranged perpendicular to the polarity of the permanent magnet 31. Figure 11 In the embodiment, the armature 32 closer to the rotating hole 331 along the X-axis direction is the first armature 32 , and the armature 32 farther from the rotating hole 331 is the second armature 32 .

[0143] See also Figure 13-17In this embodiment, the driving portion 34 includes a main body 341 and a pressure plate 342. The main body 341 is provided with a first through hole 3411 passing through along the Z-axis direction. The two ends of the first through hole 3411 are respectively provided with a first opening 3412 facing the bottom wall 131 and a second opening 3413 away from the bottom wall 131, that is, the first opening 3412 and the second opening 3413 are respectively provided at the lower end and the upper end of the first through hole 3411. The area of the second opening 3413 is larger than that of the first opening 3412. Two first supporting walls 3414 and a second supporting wall 3415 are provided in the first through hole 3411 near the second opening 3413, which are arranged at intervals along the Y-axis direction and perpendicular to the Z-axis direction. Gaps are formed between the first supporting wall 3414 and the second supporting wall 3415 and the hole wall of the first through hole 3411 on both sides along the X-axis direction. The pressing plate 342 is fixedly connected to the body 341, for example, it can extend from the second opening 3413 into the first through hole 3411 and be fixedly engaged with the inner wall of the first through hole 3411. Figure 12 The two driving parts 34 are further provided with a third opening 3416 at one end thereof, adjacent to the first opening 3412, facing each other and communicating with the first through hole 3411. It should be understood that in other embodiments, the pressure plate 342 may not be provided, but a buckle may be provided. The buckle may be an elastic buckle, with one end of the buckle head spaced apart from the first supporting wall 3414 and the second supporting wall 3415.

[0144] See also Figure 18 , Figure 18 A schematic diagram shows the contact portion 200 accommodated in the housing 11. The contact portion 200 is accommodated in the contact chamber 001. The contact portion 200 includes at least one moving contact group and at least one static contact 40. The moving contact group is provided with a moving contact 52, and the static contact 40 is provided with a static contact 41. The moving contact group extends along the Y-axis direction or forms an angle relative to the Y-axis direction, and is suitable for being directly driven by the driving part 34 to close or disconnect the moving contact 52 with the static contact 41 along the X-axis direction.

[0145] Specifically, the contact portion 200 includes four static contacts 40 and two groups of dynamic contacts. Each static contact 40 is provided with two static contacts 41 arranged along the Z-axis and a connection terminal 02 extending through the bottom wall 131 and out of the accommodating member 10. The four static contacts 40 are respectively engaged with and fixed by adhesive in four mating grooves 117 within the contact chamber 001, and the static contacts 41 extend out of the mating grooves 117 through the clearance opening 118. The projections of the static contacts 41 of each static contact 40 on a projection plane perpendicular to the Z-axis completely overlap. Of course, the number of static contacts 41 can be increased. Therefore, the static contacts 41 of the four static contacts 40 are located at the four vertices of a rectangle, the sides of which extend along the X-axis and the Y-axis, respectively. The four stationary contacts 41 on the stationary contact members 40 are respectively a first stationary contact 42, a second stationary contact 43, a third stationary contact 44, and a fourth stationary contact 45. The first stationary contact 42 and the second stationary contact 43 are arranged along the Y-axis and located on the same side of the rectangle. The third stationary contact 44 and the fourth stationary contact 45 are arranged along the Y-axis and located on the same side of the rectangle. The second stationary contact 43 and the fourth stationary contact 45 are located on the diagonals of the rectangle. Of course, in other embodiments, when the four mating slots 117 are arranged in a common quadrilateral or parallelogram shape, the four stationary contacts 41 are also located at the four corners of the quadrilateral or parallelogram.

The extension direction of the moving contact 50 intersects with the Z-axis direction. In this embodiment, the extension direction of the moving contact 50 is perpendicular to the Z-axis direction. Each moving contact 50 is provided with a fixed end and a swinging end. In this embodiment, each moving contact 50 is provided with two moving springs 51 arranged along the Z-axis direction, the number of which is equal to the number of static contacts 41 on each static contact 40. In this embodiment, specifically, in the example provided by this embodiment, each moving contact 50 is provided with two moving springs 51, each moving spring 51 is provided with a fixed end and a swinging end, the fixed ends of each moving spring 51 are connected as a whole and form the fixed end of the moving contact 50, the swinging end of each moving spring 51 forms the swinging end of the moving contact 50, and two moving contacts 52 are provided on both sides of the swinging end of each moving spring 51 facing away from each other. See also Figure 18The fixed ends of the two moving contacts 50 are located at two vertices on the diagonal of the rectangle and are fixedly connected to the corresponding static contacts 40. The moving contact points 52 on both sides of the swinging ends of the two moving contacts 50 are respectively adapted to abut or move away from the static contact points 41 on the corresponding static contacts 40. In other words, the fixed ends of the two moving contacts 50 are respectively fixedly connected to two static contacts 40 located on the diagonals of the quadrilateral formed by the four static contacts 40. The swinging ends of the two moving contacts 50 are both located between the two groups of static contacts 40 along the X-axis. In actual application, the swinging ends of the two moving contacts 50 are adapted to be driven by the two driving units 34 to move in opposite directions.

[0147] In this embodiment, still refer to Figure 18 , the two moving contacts 50 are respectively a first moving contact 55 and a second moving contact 56, the fixed end and the swing end of the first moving contact 55 are respectively a first fixed end and a first swing end, the fixed end and the swing end of the second moving contact 56 are respectively a second fixed end and a second swing end; the first fixed end is fixedly connected to the second static contact 43, and the second fixed end is fixedly connected to the fourth static contact 45; the moving contacts 52 on both sides of the first swing end are respectively adapted to abut or move away from the first static contact 42 and the fourth static contact 45, and the moving contacts 52 on both sides of the second swing end are respectively adapted to abut or move away from the second static contact 43 and the third static contact 44; the armature assembly 30 is adapted to rotate between the first position and the second position, see Figure 26 In the first position, the movable contact 52 at the first swing end is closed with the fourth static contact 45, and the movable contact 52 at the second swing end is closed with the second static contact 43. At this time, the connection terminal 02 corresponding to the second static contact 43 and the connection terminal 02 corresponding to the fourth static contact 45 are connected in series through the first movable contact 55 and the second movable contact 56 and serve as one of the current input end and the current output end respectively. The first movable contact 55 and the second movable contact 56 are connected in parallel; see Figure 28 In the second position, the moving contact 52 at the first swing end is closed with the first moving contact 52, and the moving contact 52 at the second swing end is closed with the third static contact 44.

[0148] Still see Figure 18 The movable contact 50 is provided with a bending portion protruding relative to the extending direction of the movable contact 50 , and the bending portion includes at least two first bending portions 53 and a second bending portion 54 with opposite bending directions.

[0149] See also Figure 19-20 , Figure 19 shows a schematic diagram of the contact portion 200, Figure 20 An exploded schematic diagram of the elastic member assembly 60 and the armature assembly 30 is shown. The elastic member assembly 60 is disposed between the movable contact 50 and the drive portion 34 and is adapted to deform perpendicularly to the Z-axis to provide an elastic force to the movable contact 50 toward the stationary contact 40 when the movable contact 52 and the stationary contact 41 contact. The elastic member assembly 60 includes an elastic portion extending along the Z-axis on each side of the movable contact 50, facing away from each other. The elastic member assembly 60 also includes a fixing portion connecting the two elastic portions. The first end of each elastic portion is housed within the drive portion 34, and the second end abuts the movable contact 50. The two elastic portions are configured to apply opposite elastic forces to the movable contact 50. Specifically, the contact reaction force between the movable contact 52 on one side of the movable contact 50 and the corresponding stationary contact 41 is provided by the elastic portion located on the opposite side of the movable contact 52. The fixing portion is integrally connected to the first ends of the two elastic portions and is fixedly connected to the drive portion 34. In this embodiment, the two elastic portions are symmetrically arranged about the swinging end along their elastic deformation direction. The position where the second end of the elastic portion contacts the swing end of the movable contact 50 is farther away from the fixed end than the contact position between the movable contact 50 and the stationary contact 40 .

[0150] In this embodiment, each elastic member group 60 includes an equal number of elastic members as the number of movable springs 51, and each elastic member has two elastic arms 61 that abut the corresponding movable spring 51 on opposite sides thereof, and a connecting portion 62 connecting the two elastic arms 61. The elastic arms 61 on the same side of the movable contact 50 form an elastic portion, and the connecting portions 62 form a fixed portion. The connecting portions 62 are spaced apart along the extension direction of the movable contact 50. In each elastic portion, the elastic arms 61 at least partially overlap in a projection perpendicular to the direction of elastic deformation.

[0151] The movable spring piece 51 of each movable contact 50 that is closest to the armature assembly 30 along the Z-axis direction is defined as the first movable spring piece 51, and the movable spring piece 51 that is farthest from the armature assembly 30 is defined as the second movable spring piece 51; the elastic member corresponding to the first movable spring piece 51 in the elastic member is defined as the first elastic member 63, and the elastic member corresponding to the second movable spring piece 51 is defined as the second elastic member 64, see Figure 20 The connecting portion 62 of the first elastic member 63 is provided with a third connecting wall 631 extending along the X-axis direction; the connecting portion 62 of the second elastic member 64 includes a fourth connecting wall 641 extending along the X-axis direction and fifth connecting walls 642 extending obliquely from both sides of the fourth connecting wall 641 along the X-axis direction relative to the Z-axis and Y-axis directions. The elastic arm 61 of the second elastic member 64 is integrally connected to the fifth connecting wall 642 on the same side. Figure 15-17The first elastic member 63 is adapted to be inserted into the first through-hole 3411 from the second opening 3413 until the third connecting wall 631 abuts the first supporting wall 3414 and the two elastic arms 61 are respectively inserted into the gap between the first supporting wall 3414 and the wall of the first through-hole 3411. The second elastic member 64 is adapted to be inserted into the first through-hole 3411 from the second opening 3413 until the fourth connecting wall 641 abuts the second supporting wall 3415 and the two fifth connecting walls 642 and the two elastic arms 61 are respectively inserted into the gap between the second supporting wall 3415 and the wall of the first through-hole 3411. The two elastic arms 61 of the first elastic member 63 are located between the two elastic arms 61 of the second elastic member 64 along the X-axis direction. The portion of the pressure plate 342 extending into the first through-hole 3411 is adapted to press against the third connecting wall 631 and the fourth connecting wall 641. It should be understood that when the pressure plate 342 is replaced by a clip, the clip is arranged in the first through hole 3411 and there are two clips. The two clips are respectively arranged corresponding to the third connecting wall 631 and the fourth connecting wall 641. The two clips are suitable for allowing the third connecting wall 631 and the fourth connecting wall 641 to pass through their clip heads through elastic deformation, and after the third connecting wall 631 and the fourth connecting wall 641 respectively abut against the first supporting wall 3414 and the second supporting wall 3415, the deformation is restored, and the side of the third connecting wall 631 facing away from the first supporting wall 3414 and the side of the fourth connecting wall 641 facing away from the second supporting wall 3415 are respectively pressed by their clip heads.

[0152] It should be understood that when there are four static contacts 40 and two moving contact groups, the swinging ends of the two moving contacts 50, when swinging in opposite directions, essentially switch the static contacts 41 between series and parallel. In this case, the relay is a series-parallel switching device. When there is only one static contact 40 and one moving contact group, there is only one elastic portion. In this case, the relay, like a conventional relay, functions to switch an external circuit. When there is only one moving contact group and two static contacts 40, there can be two elastic portions. In this case, the relay functions to switch an external circuit.

[0153] See also Figure 1 The auxiliary contact portion 300 includes an auxiliary moving contact 70 and two auxiliary static contacts 80. The auxiliary moving contact 70 is fixedly connected to the auxiliary push portion 35 and extends along the Z-axis direction. In this embodiment, the auxiliary moving contact 70 is a metal part. The auxiliary moving contact 70 is cylindrical and is integrally molded with the armature assembly 30 by insert injection molding, screw connection, or interference fit. It has an arc-shaped first contact surface. In this embodiment, the first contact surface is composed of the side surface of the auxiliary moving contact 70. Each auxiliary static contact 80 is provided with a rigid portion 81 inserted into the fixed seat 119 along the Z-axis direction and an auxiliary contact portion 82 connected to the rigid portion 81 and extending perpendicular to the X-axis direction. See Figure 8The two auxiliary contact portions 82 are arranged along the Z-axis. In this embodiment, the auxiliary contact portions 82 extend along the Y-axis and are adapted to deform along the X-axis. The auxiliary contact portions 82 are provided with a second contact surface perpendicular to the X-axis. In this embodiment, the second contact surface extends along the Y-axis. On a projection plane perpendicular to the Z-axis, the projection of one auxiliary static contact 80 overlaps the projection of the other auxiliary static contact 80. The auxiliary movable contact 70 is driven by the auxiliary push portion 35 to contact or move away from the two auxiliary static contacts 80, thereby connecting or disconnecting the two auxiliary static contacts 80. The two auxiliary contact portions 82 are adapted to contact the two sides of the auxiliary movable contact 70 that extend out of the auxiliary push portion 35 along the Z-axis.

[0154] In practice, the rigid portion 81 is formed from two rigid sheets that fit together and are integrally formed. The auxiliary contact portion 82 is integrally connected to one of the rigid sheets. One of the rigid portions 81 is further provided with a rigid segment 811 extending along the Y-axis. This segment 811 opposes the abutment portion 142 of the fixing frame 14. The arrangement of this segment 811 ensures that the lengths of the flexible deformable portions of the two auxiliary static contacts 80 are consistent, thereby ensuring that the flexible deformable portions of the two auxiliary static contacts 80 have similar elastic deformation capabilities.

[0155] The auxiliary contact portion 82 is also opposite to the limiting portion 141 of the fixing frame 14 . The limiting portion 141 is adapted to abut against the two auxiliary static contacts 80 to limit the distance that the two auxiliary contact portions 82 can move toward the auxiliary movable contact 70 .

[0156] The assembly process of this embodiment is as follows:

[0157] The coil assembly 20 is placed in the housing 11 from the second end thereof, and the connecting section 241 of the yoke 24 is inserted into the mounting groove, and the magnetic drive end 242 extends out of the first opening 3412. After insertion, the coil assembly 20 and the housing 11 are limited in position along the X-axis and Y-axis directions, and the upward movement is limited by the bottom of the mounting groove, as can be seen in FIG. Figure 8 ;

[0158] Insert the rigid portions 81 of the two auxiliary static contacts 80 into the fixing seat 119. The two auxiliary contact portions 82 are spaced apart along the Z-axis and extend along the Y-axis. The rigid segments 811 also extend along the Y-axis.

[0159] Two elastic member groups 60 are respectively installed in the bodies 341 of the two driving parts 34 of the armature assembly 30. Specifically, the first elastic member 63 is first inserted into the first through hole 3411 from the second opening 3413 until the third connecting wall 631 abuts the first supporting wall 3414 and the two elastic arms 61 are respectively inserted into the gap between the first supporting wall 3414 and the hole wall of the first through hole 3411. Then, the second elastic member 64 is inserted into the first through hole 3411 from the second opening 3413 until the fourth connecting wall 641 abuts the second supporting wall 3415 and the two fifth connecting walls 642 and the two elastic arms 61 are respectively inserted into the holes of the second supporting wall 3415 and the first through hole 3411. The gap between the walls is formed, and the two elastic arms 61 of the first elastic member 63 are located between the two elastic arms 61 of the second elastic member 64 along the X-axis direction; in each elastic portion, the second end of each elastic arm 61 is arranged along the Z-axis direction and each elastic arm 61 at least partially overlaps on the projection surface perpendicular to the elastic deformation direction; then the pressure plate 342 is snapped into the body 341, so that the part of the pressure plate 342 extending into the first through hole 3411 abuts against the third connecting wall 631 and the fourth connecting wall 641, so that the first elastic member and the second elastic member and the driving part 34 are limited in the X-axis direction, the Y-axis direction and the Z-axis direction, and the elastic member group 60 is relatively fixed to the armature assembly 30, as can be seen from the diagram. Figure 11-17 ;

[0160] The armature assembly 30 equipped with the elastic member group 60 is placed into the housing 11 from the first end of the housing 11, and the two driving parts 34 are respectively inserted into the two communicating holes 1131 of the first partition 113, and the rotation hole 331 of the armature assembly 30 is inserted into the protruding shaft of the first partition 113; each magnetic driving end 242 is respectively located between the first attraction part 321 and the second attraction part 322; the two magnetic driving ends 242 are located between the rotation axis of the armature assembly 30 and the axis of the coil winding 22 along the X-axis direction, as shown in FIG. Figure 8 ;

[0161] The fixing frame 14 is placed into the housing 11 from the first end of the housing 11 and is limitedly matched with the housing 11 along the X-axis direction and the Y-axis direction. The fixing frame 14 is supported in the housing 11, and the convex shaft of the fixing frame 14 is inserted into the rotating hole 331 of the armature assembly 30. The fixing frame 14 is also limitedly matched with the yoke 24 along the X-axis direction and the Y-axis direction and abuts against the yoke 24. The limiting portion 141 of the fixing frame 14 faces the auxiliary contact portion 82, and the abutting portion 142 of the fixing frame 14 abuts against the rigid section 811 so that the rigid portion 81 of the auxiliary static contact 80 is fixed relative to the housing 11. Figure 22 and Figure 24 ;

[0162] The first cover 12 is clamped to the outer wall of the first end of the shell 11 and fixed by glue, and the fixing frame 14 is fixed in the shell 11. Figure 22 ;

[0163] Insert the four static contacts 40 into the four matching grooves 117 in the first groove from the second end of the housing 11 and make the static contacts 41 extend out of the clearance opening 118. The dynamic contact 50 fixed to the static contacts 40 is also located in the first groove. Figure 1 8 The swing ends of the two movable contacts 50 are respectively inserted between the corresponding elastic member groups 60, and at the same time, the first movable reed 51 is inserted into the driving portion 34 through the third opening 3416 of the two driving portions 34;

[0164] The second cover body 13 is clamped to the outer wall of the second end of the shell 11 and fixed by glue, and the connecting terminal 02, the lead terminal 03 and the signal terminal 01 all pass through the bottom wall 131 and extend out of the accommodating part 10. The support surface 1311 is abutted against the step surface perpendicular to the Z-axis direction formed in the shell 11, and the second isolation plate 132 is abutted against the inner wall of the shell 11 along the X-axis and Y-axis directions. The second isolation plate 132 is located between the coil winding 22 and the contact part 200 along the X-axis direction, and cooperates with the shell 11 to form a contact chamber 001 and cooperates with the shell 11 to limit the displacement of the coil assembly 20 along the Z-axis direction; the installation is completed.

[0165] After installation is complete, see Figures 21-24 , Figures 21-24 The top view and cross-sectional view of the relay are shown. The moving contact group and the armature assembly 30 have at least partial overlap along the Z-axis direction. The coil winding 22 is located outside the contact chamber 001. On the projection plane perpendicular to the X-axis direction, the projection of the coil winding 22 at least partially overlaps with the projection of the contact part 200. The rotation axis of the armature assembly 30 and the axis of the coil winding 22 are arranged along the X-axis direction. The two magnetic drive ends 242 are located between the rotation axis of the armature assembly 30 and the axis of the coil winding 22 along the X-axis direction. The auxiliary pushing portion 35 and the coil winding 22 are arranged along the Z-axis direction. In this embodiment, the auxiliary pushing portion 35 is located above the coil winding 22. The first end of the elastic portion is fixed to the driving portion 34 and is accommodated in the driving portion 34. The signal terminal 01, the connecting terminal 02 and the lead-out terminal 03 all pass through the bottom wall 131 and extend out of the accommodating portion 10.

[0166] See also Figures 25-28 , Figures 25-28 Schematic diagram showing the armature assembly in the first position and the second position. The working process of the relay of this embodiment is as follows:

[0167] When the signal terminal 01 receives the first pulse signal, the armature assembly 30 rotates from the second position to the first position, see Figure 25 The first attracting portion 321 attracts the first magnetic drive end 243, and the second attracting portion 322 attracts the second magnetic drive end 244; see Figure 26, one driving part 34 drives the movable contact 52 at the first swing end to close with the fourth static contact 45 through the elastic member group 60, and the other driving part 34 drives the movable contact 52 at the second swing end to close with the second static contact 43 through the elastic member group 60, and the connecting terminal 02 corresponding to the second static contact 43 and the connecting terminal 02 corresponding to the fourth static contact 45 are connected in series through the first movable contact 55 and the second movable contact 56 and serve as one of the current input end and the current output end respectively, and the first movable contact 55 and the second movable contact 56 are connected in parallel; see Figure 25 , the auxiliary moving contact 70 moves away from the two auxiliary static contacts 80 and causes the two auxiliary static contacts 84 to be disconnected;

[0168] When the signal terminal 01 receives the second pulse signal, the armature assembly 30 rotates from the first position to the second position. Figure 27 , the first attracting portion 321 attracts the second magnetic drive end 244, and the second attracting portion 322 attracts the second magnetic drive end 244; see Figure 28 , one of the driving parts 34 drives the movable contact 52 at the first swing end to close with the first static contact 42 through the elastic member group 60, and the other driving part 34 drives the movable contact 52 at the second swing end to close with the third static contact 44 through the elastic member group 60, the connecting terminal 02 corresponding to the first static contact 42 is connected in series with the connecting terminal 02 corresponding to the second static contact 43 through the first movable contact 55, the connecting terminal 02 corresponding to the third static contact 44 is connected in series with the connecting terminal 02 corresponding to the fourth static contact 45, the connecting terminal 02 corresponding to the first static contact 42 is connected to the connecting terminal 02 corresponding to the fourth static contact 45 and together constitutes one of the current input end or the current output end, the connecting terminal 02 corresponding to the second static contact 43 is connected to the connecting terminal 02 corresponding to the third static contact 44 and together constitutes the other of the current input end or the current output end; see Figure 27 , the auxiliary moving contact 70 abuts against the two auxiliary static contacts 80 and causes the two auxiliary static contacts 80 to be conductive.

[0169] In this embodiment, the contact portion 200 and the armature assembly 30 are arranged overlappingly along the Z-axis direction, and the coil winding 22 and the contact portion 200 are arranged overlappingly along the X-axis direction. Therefore, the relay as a whole occupies a small area on the projection plane perpendicular to the Z-axis direction, that is, the relay occupies a small area in the X-axis direction and the Y-axis direction. The relay also occupies a small area on the projection plane perpendicular to the X-axis direction, that is, the relay occupies a small area in the Y-axis direction and the Z-axis direction. Therefore, it can effectively solve the problem of the relay occupying a large board area when connected to the PCB board along the Z-axis direction, and at the same time, the relay occupies a small area along the Z-axis direction. The height is relatively small, and the projection of the coil winding 22 and the projection of the contact portion 200 are arranged along the X-axis direction, which increases the creepage distance between the coil winding 22 and the contact portion 200, so that the electrical distance between the weak-current contact terminal of the magnetic circuit portion 100 and the strong-current contact terminal of the contact portion 200 is maintained within a relatively large range, improving the electrical isolation problem. As a result, when the relay and the PCB are matched along the Z-axis direction, the PCB board area is small, the height occupancy is small, and the electrical isolation distance between the strong and weak-current contact terminals is large; thereby, the relay does not need to be connected to the PCB board along the X-axis direction or the Y-axis direction.

[0170] In this embodiment, the armature assembly 30 is provided with a drive portion 34 extending along the Z-axis. The movable contact assembly is adapted to be directly driven by the drive portion 34 to close or open the movable contact 52 with the stationary contact 41 along the X-axis. Compared to a scheme in which a push card is provided between the drive portion 34 and the movable contact assembly, the relay is shorter in the Z-axis direction and shorter in the X-axis direction, and the problem of jamming during operation of the push card is avoided, making the overall operation of the relay more stable. In addition, the movable contact assembly and the armature assembly 30 are ensured to have at least partial overlap along the Z-axis. By extending the movable contact assembly along the Y-axis or arranging it at an angle relative to the Y-axis, the movable contact assembly further occupies less space along the X-axis, which facilitates product miniaturization.

[0171] In this embodiment, the coil assembly 20 also includes two magnetic drive ends 242 arranged along the Y-axis direction. The axis of the coil winding 22 extends along the Y-axis direction, so that the coil winding 22 occupies less space along the X-axis direction and the Z-axis direction, which can further save space.

[0172] In this embodiment, the armature assembly 30 rotates about a rotation axis extending along the Z-axis. The rotation axis of the armature assembly 30 and the coil winding 22 are arranged along the X-axis, facilitating the layout of the armature assembly 30 and coil assembly 20. The drive unit 34 is mounted on the insulating member 33, making it easier to manufacture. The armature assembly 30 is configured for rotation, which saves space along the X-axis compared to linear motion. The closed magnetic circuit formed when engaged eliminates magnetic gaps, resulting in higher magnetic efficiency and greater attraction force, further improving contact stability between the moving contact assembly and the stationary contact.

[0173] In this embodiment, the contact portion 200 is accommodated in the contact chamber 001 , and the coil winding 22 is located outside the contact chamber 001 , which further increases the creepage distance between the coil winding 22 and the contact portion 200 and improves the electrical isolation problem.

[0174] In this embodiment, the two magnetic drive ends 242 and the coil winding 22 are arranged along the Z-axis direction. On the projection plane perpendicular to the X-axis direction, the projection of the coil winding 22 and the projection of the contact part 200 at least partially overlap, so that the two magnetic drive ends 242 are away from the contact part 200 along the Z-axis direction, so that the strong and weak current parts are separated farther in space, making it easier to meet the electrical isolation and creepage distance requirements. In addition, space is left on the side of the coil winding 22 close to the magnetic drive end 242 along the Z direction, which facilitates the subsequent installation of the auxiliary contact part 300 and improves space utilization.

[0175] In this embodiment, since the two magnetic drive ends 242 and the coil winding 22 are arranged along the Z-axis, there are two solutions to ensure the installation of the armature assembly 30. One solution is to place the two magnetic drive ends 242 away from the coil winding 22 in the X-axis direction. This solution will cause the coil assembly 20 to occupy a larger space in the X-axis direction and bring the contact portion 200 and the magnetic drive ends 242 closer to each other, which is not conducive to electrical isolation. The other solution is the solution of this embodiment, in which the two magnetic drive ends 242 are located between the rotation axis of the armature assembly 30 and the axis of the coil winding 22 along the X-axis direction. This allows the two magnetic drive ends 242 to be away from the contact portion 200, improving the electrical isolation problem. On the projection plane perpendicular to the Z-axis direction, the coil winding 22 covers the magnetic drive ends 242, and the coil assembly 20 occupies less space in the X-axis direction, further reducing the length of the accommodating part 10 along the X-axis direction. In addition, it also allows the magnetic drive ends 242 to be further away from the contact portion 200, improving the electrical isolation problem. In addition, in this structure, the rotation axis of the armature assembly 30 is close to the side where the contact part 200 is located. When the armature assembly 30 drives the moving contact group to rotate, the relative movement between it and the moving contact group in the radial direction is smaller, which can not only ensure that the moving contact 52 and the static contact 41 are in reliable contact, but also reduce friction resistance, so that the driving force required by the coil assembly 20 is smaller, and it is also more conducive to reducing the volume and space occupancy of the coil assembly 20.

[0176] In this embodiment, the arrangement direction of the rotation axis of the driving portion 34 and the armature assembly 30 is perpendicular to the polarity direction of the permanent magnet 31, so that the distance between the driving portion 34 and the rotation axis is the shortest, and the length of the accommodating portion 10 along the Y-axis direction that needs to be provided for the driving portion 34 is smaller, thereby reducing the length of the accommodating portion 10 along the Y-axis direction; in addition, compared with the solution in which the arrangement direction of the rotation axis of the driving portion 34 and the armature assembly 30 is obliquely intersected with the polarity direction of the permanent magnet 31, the contact portion 200 can also be moved away from the magnetic drive end 242 along the X-axis direction while reducing the occupied space in the X-axis direction.

[0177] In this embodiment, the coil assembly 20 is inserted into the accommodating part 10 from the second end opening of the accommodating part 10. The setting of the mounting groove can limit the coil assembly 20 along the X-axis direction, the Y-axis direction and the Z-axis direction by limiting the connecting section 241 of the yoke 24, thereby ensuring the limited cooperation between the coil assembly 20 and the accommodating part 10 after the second cover 13 and the shell 11 are fixed; the setting of the reinforcing wall 116 further improves the strength of the mounting seat 115 and ensures the structural stability; and when welding is required, only the second cover 13 is made of high-temperature resistant material, and the overall cost is lower. The setting of the support surface 1311 and the isolation plate ensures a close fit between the second cover 13 and the shell 11. In particular, the isolation plate increases the creepage distance between the contact portion 200 and the coil winding 22, thereby further improving the electrical isolation effect between the strong and weak current terminals.

[0178] In this embodiment, the extension direction of the moving contact 50 intersects with the Z-axis direction. Therefore, the elastic part intersects with the extension direction of the moving contact 50, effectively utilizing the space of the accommodating part 10 in the Z-axis direction and reducing the length of the accommodating part 10 along the X-axis direction. In this way, the width of the elastic part can be widened and the length of the elastic part can be extended as much as possible without changing the size of the moving contact 52, the width of the moving contact 50, and the overall length of the moving contact group. Widening the width of the elastic part can enable the elastic part group 60 to provide greater contact pressure to the moving contact 50, and extending the length of the elastic part can eliminate the need to set an excessively large inclination angle of the elastic part, thereby reducing the stress on the elastic part, avoiding fatigue failure, and improving the service life. Based on this, this embodiment can enable the moving contact 50 to obtain greater contact pressure when space is limited, thereby improving the service life of the elastic part, thereby improving the connection reliability of the moving contact 52 and the static contact 41. In addition, in this embodiment, during the driving process of the armature assembly 30, the contact position between it and the elastic part will not change or change slightly along the Z-axis direction, the elastic coefficient of the elastic part remains stable or relatively stable, and the elastic force changes linearly without sudden changes. The final contact pressure range is controllable, so that the required magnetic driving force can be easily controlled and ensured that the dynamic contact 50 can be reliably driven to contact or move away from the static contact 40.

[0179] In this embodiment, the dynamic contact 50 extends in a direction perpendicular to the Z-axis direction, further reducing the space occupied by the dynamic contact 50 in the Z-axis direction, and reducing the influence of the elastic member group 60 on the size of the dynamic contact 52 and the size occupied along the extension direction of the dynamic contact 50, and making the elastic force provided by the elastic member group 60 toward the static contact 40 greater.

[0180] In this embodiment, two drive units 34 are provided, one at each end of the armature assembly 30 along the Y-axis, each driving a respective spring assembly 60. This results in a simple and practical structure. The swinging ends of the two movable contacts 50 are adapted to be driven in opposite directions by the two drive units 34. Therefore, by closing the two movable contacts 52 at the swinging ends with different stationary contacts 41, switching between series and parallel connections of the different stationary contacts 41 can be achieved.

[0181] In this embodiment, the four static contacts 40 are located at the four corners of the rectangle. Compared with a parallelogram or other quadrilateral structures, the contact portion 200 occupies a smaller space along the Y-axis direction.

[0182] In this embodiment, the movable contact 50 is provided with a bent portion that protrudes relative to the direction in which the movable contact 50 extends. This bent portion absorbs the movement of the movable contact 50 in the Y-axis direction when the movable contact 52 and the stationary contact 41 close or open along the X-axis, preventing the movable contact 52 and the stationary contact 41 from staggering along the Y-axis. The bent portion includes at least two first and second bent portions 53 and 54, each bending in opposite directions. This increases the flexibility of the movable contact 50, further preventing the movable contact 52 and the stationary contact 41 from staggering along the Y-axis, and also prevents interference between the movable contact 50 and the housing 11 during movement. Placing one of the bent portions near the fixed end of the movable contact 50 also facilitates determining the deformation fulcrum.

[0183] In this embodiment, each static contact 40 is provided with at least two static contacts 41 arranged along the Z-axis. Correspondingly, the swinging end of the movable contact 50 is divided into multiple, one-to-one correspondences with each static contact 41, each with a movable contact 52. When the movable contact 50 contacts the corresponding static contact 40, the current flowing through the movable contact 50 is split into multiple paths, thereby reducing the resistance of the movable contact 50 and improving its overall current-carrying capacity. The projections of the static contacts 41 on a plane perpendicular to the Z-axis completely overlap. Compared to a case where the static contacts 41 of each static contact 40 are staggered along the Y-axis, this results in a smaller space occupied by the contact portion 200 in the Y-axis.

[0184] In this embodiment, the elastic member group 60 is arranged between the moving contact 50 and the driving part 34 and is suitable for deforming in a direction perpendicular to the Z-axis to provide an elastic force to the moving contact 50 toward the static contact 40 when the moving contact 52 and the static contact 41 are in contact. Therefore, the driving part 34 can drive the moving contact 50 to move through the elastic member group 60 so that the moving contact 52 and the static contact 41 are closed along the X-axis direction. The elastic member group 60 can apply contact pressure to the moving contact 52 to close with the static contact 41, thereby ensuring stable contact between the moving contact 52 and the static contact 41.

[0185] In this embodiment, the elastic member group 60 is provided with an elastic portion extending along the Z-axis direction. The first end of the elastic portion is accommodated in the driving portion 34, and the second end is abutted or fixed to the dynamic contact member 50. Compared with the solution in which the elastic portion is outside the driving portion 34, the connection between the elastic portion and the driving portion 34 is more stable and occupies less space in the X-axis direction.

[0186] In this embodiment, the position where the second end of the elastic part contacts the swinging end of the moving contact 50 is farther away from the fixed end than the contact position between the moving contact 50 and the static contact 40, so that the torque exerted by the elastic part on the moving contact 50 is greater. When the elastic part is pressurized by the armature assembly 30, the contact stability between the moving contact 52 and the static contact 41 is higher.

[0187] In this embodiment, there are two elastic parts, which are respectively arranged on two sides of the swinging end of the moving contact 50, away from each other, and are respectively used to provide contact reaction force to the moving contacts 52 on both sides of the moving contact 50. Compared with the fixed connection or abutment between the elastic part and other positions of the moving contact 50, the elastic part group 60 applies a greater contact pressure to the moving contact 52 and the static contact 41 to close the moving contact 50. In addition, the above arrangement enables the moving contacts 52 on both sides of the swinging end to be subjected to the contact pressure of the elastic part, ensuring the stable closure of the moving contacts 52 on both sides and the corresponding static contacts 41.

[0188] In this embodiment, the two elastic parts are symmetrically arranged about the swing end along their elastic deformation direction. Compared with the two elastic parts being staggered along the extension direction of the dynamic contact 50, the driving forces applied by the two elastic parts to the dynamic contact 50 are closer in magnitude, thereby ensuring that the dynamic contact 52 on each side of the dynamic contact 50 has a larger contact pressure.

[0189] In this embodiment, the elastic member group 60 is also provided with a fixing portion; the fixing portion is connected to the first ends of the two elastic portions as a whole, and is used to be fixedly connected to the driving portion 34; the second end of the elastic portion abuts against the moving contact 50, which is beneficial to the assembly of the elastic portion and the moving contact 50, especially when the moving contact 50 is composed of multiple elastic sheets stacked together, the two elastic portions only need to abut against the two sides of the moving contact 50 that are away from each other.

[0190] In this embodiment, the arrangement of multiple elastic members enables each movable spring 51 of each movable contact member 50 to be driven by an elastic member, and the two elastic arms 61 of the elastic member clamp the two sides of the movable spring 51, which is simple to assemble and ensures that each movable contact point 52 of each movable contact member 50 has a higher contact pressure; the connecting parts 62 are arranged at intervals along the extension direction of the movable contact member 50, thereby avoiding interference between the elastic members.

[0191] In this embodiment, in each elastic portion, the elastic arms 61 at least partially overlap on the projection surface perpendicular to the elastic deformation direction. Compared with the solution in which the elastic arms 61 are arranged along the extension direction of the dynamic spring piece 51, this is beneficial for the elastic members to apply a greater contact pressure to the corresponding dynamic spring piece 51.

[0192] In this embodiment, the connecting portion 62 of the second elastic member 64 includes a fourth connecting wall 641 extending along the X-axis direction and a fifth connecting wall 642 extending obliquely from the fourth connecting wall 641 on both sides along the X-axis direction relative to the Z-axis direction and the Y-axis direction. The elastic arm 61 of the second elastic member 64 is connected as a whole with the fifth connecting wall 642 on the same side, which is beneficial to avoid interference between the elastic members.

[0193] In this embodiment, the swing end of the first movable spring 51 is also located in the driving portion 34, which is beneficial to reducing the length of the elastic member along the Z-axis direction, reducing the length of the relay in the Z-axis direction, and ensuring that the driving portion 34 abuts against the first elastic member 63 to elastically deform the elastic arm 61.

[0194] In this embodiment, the setting of the auxiliary contact part 300 is conducive to monitoring the operation of the relay. The auxiliary contact part 300 is away from the rotation axis along the X-axis direction, which is conducive to making the terminals of the auxiliary contact part 300 away from the terminals of the contact part 200 in the X-axis direction, thereby increasing the distance between the auxiliary contact part 300 and the contact part 200 and improving the electrical isolation problem.

[0195] In this embodiment, an auxiliary pushing portion 35 is further provided on the side of the insulating member 33 away from the rotation axis. The auxiliary pushing portion 35 and the coil winding 22 are arranged along the Z-axis direction, and the auxiliary moving contact 70 extends along the Z-axis direction. Each auxiliary static contact 80 is provided with an auxiliary contact portion 82 extending perpendicular to the X-axis direction, and the two auxiliary contact portions 82 are arranged at intervals along the Z-axis direction; the auxiliary moving contact 70 is driven by the auxiliary pushing portion 35 to contact or move away from the two auxiliary static contacts 80 to make the two auxiliary static contacts 80 conductive or disconnected, making full use of the space on the side of the coil winding 22 close to the magnetic drive end 242 along the Z-axis direction, thereby improving space utilization, and the setting of the auxiliary contact portion 300 makes it mainly occupy space in the Z-axis direction and occupies little space in the X-axis direction. In this way, the auxiliary moving contact 70 can be fixed to the armature assembly 3 0 so that the auxiliary moving contact 70 moves with the armature assembly 30, and the extension direction of the auxiliary moving contact 70 is set to be parallel to the rotation axis of the armature assembly 30, so that the entire auxiliary contact portion occupies a smaller size on both sides of the armature assembly 30. The maximum size occupied is only the distance between the auxiliary moving contact 70 and the auxiliary static contact 80 when they are disconnected, and the space occupied is small. Therefore, as long as the auxiliary contact portion can avoid the coil assembly 20, the auxiliary contact portion can be easily installed in the limited space on both sides of the armature assembly 30 without increasing the volume of the accommodating part 10. The auxiliary contact portion 300 in this embodiment occupies less space than the standard micro switch part, and the position of the terminal of the auxiliary contact portion 300 can be adjusted as needed, and the structural design is simpler. In addition, after such a design, the lead terminal 03 of the auxiliary contact portion 300 and the terminal (weak current) of the coil winding 22 are both away from the terminal (strong current) of the contact portion 200 along the X-axis direction, which is conducive to the isolation of strong and weak current terminals.

[0196] In this embodiment, the auxiliary static contact 80 is suitable for deformation along the X-axis direction. Since the two magnetic drive ends 242 are located between the rotation axis of the armature assembly 30 and the axis of the coil winding 22 along the X-axis direction, the tangential component of the force along the X-axis transmitted to the auxiliary push portion 35 by the armature assembly 30 is relatively large, which can give the auxiliary moving contact 70 and the auxiliary contact portion 82 a certain contact pressure. In other words, by designing the position of the auxiliary static contact 80, when the armature assembly 30 is rotated into place, the abutment of the auxiliary moving contact 70 against the auxiliary contact portion 82 causes the auxiliary static contact 80 to form appropriate deformation, which is conducive to obtaining a more stable contact relationship after conduction. The auxiliary contact portion 82 extends parallel to the Y-axis. Compared to a solution in which the auxiliary contact portion 82 extends along the Z-axis, this avoids occupying too much space in the Z-axis direction and prevents the auxiliary static contact 80 from forming an angle with the auxiliary movable contact 70 when the auxiliary movable contact 70 abuts against two auxiliary contact portions 82, thereby preventing reliable contact. Furthermore, when the auxiliary contact portion 82 extends along the Y-axis, it is perpendicular to the extension direction of the auxiliary movable contact 70. Therefore, even if the auxiliary contact portion 82 deforms during the rotation of the auxiliary movable contact 70, the auxiliary contact portion 82 and the auxiliary movable contact 70 maintain the same contact area, thereby not affecting the contact reliability between the auxiliary movable contact 70 and the auxiliary contact portion 82. On a projection plane perpendicular to the Z-axis, the projection of one auxiliary static contact 80 overlaps the projection of the other auxiliary static contact 80. That is, the two auxiliary static contacts 80 are not offset from each other along the X-axis, thereby further saving space and facilitating relay miniaturization.

[0197] In this embodiment, the fixed seat 119 is fixed to the first side wall 111, which is easy to process and has a stable structure; the auxiliary static contact 80 is provided with a rigid part 81 inserted into the fixed seat 119, and the rigid part 81 is provided with a lead terminal 03. The auxiliary contact part 82 is connected to the rigid part 81 as a whole, which is conducive to ensuring that the two auxiliary contact parts 82 are located on the same plane, thereby improving the connection reliability.

[0198] In this embodiment, the two rigid parts 81 are connected as one by insert injection molding, and the two rigid parts 81 can be installed synchronously, which is beneficial to reducing the installation error caused by independent installation of each other, improving the accuracy of the relative position of the two rigid parts 81, and further ensuring that the two auxiliary contact parts 82 are located on the same plane, thereby further improving the connection reliability between the auxiliary dynamic contact 70 and the two auxiliary static contacts 80.

[0199] In this embodiment, the auxiliary movable contact 70 is cylindrical, which has a simple structure, occupies a small space in a plane perpendicular to the Z-axis, and facilitates secure connection with the armature assembly 30. The second contact surface extends along the Y-axis, perpendicular to the extension direction of the auxiliary movable contact 70. Therefore, even if the auxiliary contact portion 82 deforms during the rotation of the auxiliary movable contact 70, the auxiliary contact portion 82 and the auxiliary movable contact 70 maintain the same contact area, thereby maintaining the contact reliability between the auxiliary movable contact 70 and the auxiliary contact portion 82.

[0200] In this embodiment, the auxiliary push portion 35 is positioned offset from the center of the armature assembly 30 along the Y-axis. Thus, compared to a solution in which the auxiliary push portion 35 is positioned at the center of the armature assembly 30 along the Y-axis, the auxiliary push portion 35 and the auxiliary movable contact 70 have a greater travel range when the armature assembly 30 rotates, thereby facilitating reliable disconnection between the auxiliary movable contact 70 and the auxiliary static contact 80. The auxiliary push portion 35 is located in the middle of the armature assembly 30 along the Z-axis, and the space it occupies along the Z-axis encompasses the interior of the armature assembly 30, without occupying any additional space. This saves space and facilitates further miniaturization of the relay. The two auxiliary contact portions 82 are adapted to respectively contact the two sides of the auxiliary movable contact 70 that extend out of the auxiliary push portion 35 along the Z-axis. The two auxiliary contact portions 82 are relatively far apart, minimizing the likelihood of interference.

[0201] In this embodiment, the limiting portion 141 is suitable for abutting the two auxiliary static contacts 80 to limit the distance that the two auxiliary contact portions 82 move toward the auxiliary moving contact 70, which can prevent the auxiliary contact portion 82 from being excessively deformed due to adhesion when the auxiliary moving contact 70 is disconnected from the auxiliary contact portion 82, thereby avoiding disconnection failure between the auxiliary contact portion 82 and the auxiliary moving contact 70 and improving the disconnection stability.

[0202] In this embodiment, each auxiliary dynamic contact 70 is provided with a first contact surface suitable for abutting the auxiliary contact portion 82, the first contact surface is arc-shaped, and the auxiliary contact portion 82 is provided with a second contact surface parallel to the Z-axis direction. When the first contact surface and the second contact surface are in contact, it is line contact, the contact area is larger than that of point contact, and the contact stability is reliable.

[0203] In this embodiment, the connection terminal 02 and the signal terminal 01 both extend out of the same side of the accommodation component 10 along the Z-axis direction, which facilitates the connection of the relay to the PCB board along the Z-axis direction.

[0204] In this embodiment, the connecting terminal 02 and the signal terminal 01 extend out of the accommodating part 10 along the Z-axis direction close to the side of the contact portion 200, so that the connecting terminal 02 and the signal terminal 01 do not need to be bent to avoid the armature assembly 30 when extending out of the accommodating part 10 along the Z-axis direction. They are not easily damaged, and the assembly is simple and material costs are saved.

[0205] In this embodiment, the signal terminal 01, the connecting terminal 02 and the lead-out terminal 03 all pass through the bottom wall 131 and extend out of the accommodating component 10. Since the coil winding 22 and the contact portion 200 are arranged along the X-axis direction, the signal terminal 01 and the connecting terminal 02 are staggered from each other along the X-axis direction on the bottom wall 131, and the signal terminal 01 is located on or on both sides of the coil winding 22 along the Y-axis direction. Therefore, the signal terminal 01, the connecting terminal 02 and the lead-out terminal 03 are staggered from each other along the Y-axis direction. Therefore, the signal terminal 01, the connecting terminal 02 and the lead-out terminal 03 are staggered from each other on the bottom wall 131, further meeting the electrical isolation and creepage distance requirements.

[0206] In this embodiment, the accommodating member 10 includes a shell 11, a first cover body 12, a second cover body 13 and a fixing frame 14, so that the armature assembly 30 can be placed in the shell 11 at the first end of the shell 11 and rotatably connected to the shell 11 and the fixing frame 14. The first cover body 12 is fixed to the outer wall of the first end of the shell 11, and the fixing frame 14 is accommodated in the shell 11 and fixed relative to the shell 11. The separate setting of the first cover body 12 and the fixing frame 14 is more conducive to installation and avoids the uneven force inside and outside the shell 11 caused by the integral molding of the first cover body 12 and the fixing frame 14, as well as the resulting installation effort and assembly difficulties.

[0207] Example 2

[0208] The structure of embodiment 2 is basically the same as that of embodiment 1, except that the structure of the elastic member group 60 is different from that of the driving portion 34. In this embodiment, the fixed portion is fixedly connected to the movable contact member 50 and is integrally connected to the second end of the elastic portion, while the first end of the elastic portion abuts against the driving portion 34. Figure 29 Each elastic portion is provided with an elastic arm 61 extending along the Z-axis direction, the same number as the movable spring piece 51. The elastic arms 61 are arranged at intervals along the extension direction of the movable spring piece 51 and are suitable for driving each movable spring piece 51 respectively. The fixed portion is provided with a second connecting wall 66 integrally connected to the second end of the elastic arm 61 corresponding to each elastic arm 61. Each second connecting wall 66 is fixedly connected to each movable spring piece 51 at the location of the movable contact 52; the first ends of the elastic arms 61 of each elastic portion are separated from each other along the Z-axis direction. In each elastic portion, each elastic arm 61 has a uniform shape and size and extends from the corresponding movable spring piece 51 along the Z-axis toward one side of the driving portion 34. Along the Z-axis, the elastic arm 61 corresponding to the movable spring piece 51 farther from the driving portion 34 is further from the fixed end of the movable contact 50. The width of each movable spring piece 51 is uniform at all locations along its extension direction. Each second connecting wall 66 is configured to have the same width as each movable spring piece 51 to provide better fixing strength and allow each elastic arm 61 to extend from the upper end of the corresponding movable spring piece 51 to avoid interference with other movable spring pieces 51. The corresponding driving portion 34 may be provided with only a downwardly opening receiving groove for accommodating the first end of the elastic portion, with the first end of each elastic portion abutting against the groove wall of the receiving groove 343.

[0209] In this embodiment, the fixed portion is fixedly connected to the swinging end of the movable contact 50 and integrally connected to the second end of the elastic portion. This makes molding the movable contact 50 easier than if the elastic portion were directly molded onto the movable contact 50. The fixed portion is fixedly connected to the movable contact 50 at the location of the movable contact 52. Compared to other locations, the elastic portion directly applies contact pressure to the movable contact 52, ensuring more stable contact between the movable contact 52 and the stationary contact 41.

[0210] In this embodiment, each elastic portion is provided with an equal number of elastic arms 61 as the number of movable springs 51. Each elastic arm 61 is spaced apart along the extension direction of the movable spring 51 and is adapted to drive each movable spring 51, ensuring that the movable contact 52 on each movable spring 51 has a high contact pressure, thereby ensuring stable closure between each movable contact 52 and the corresponding static contact 41. Each elastic member is also provided with a second connecting wall 66 integrally connected to the second end of each elastic arm 61, corresponding to each elastic arm 61. Each second connecting wall 66 extends along the extension direction of the movable spring 51 and is fixedly connected to each movable spring 51. This facilitates the mutual non-interference of the elastic arms 61. Furthermore, compared to a solution in which each elastic arm 61 is separately formed on each movable spring 51, the movable spring 51 is easier to process and form.

[0211] In this embodiment, in each elastic portion, each elastic arm 61 extends from the corresponding dynamic spring piece 51 along the Z-axis direction toward one side of the driving portion 34. In this way, each elastic arm 61 forms an avoidance with the corresponding dynamic spring piece 51 along the Z-axis direction, so that elastic deformation can be better achieved; the shape and size of each elastic arm 61 are designed to be consistent, which is conducive to providing more consistent contact pressure to each dynamic spring piece 51 and ensuring the consistency of the working parameters of each dynamic spring piece 51; along the Z-axis direction, the elastic arm 61 corresponding to the dynamic spring piece 51 that is farther away from the driving portion 34 is farther away from the fixed end of the dynamic contact 50, so that the elastic arm 61 also avoids other dynamic spring pieces 51 during the extension process along the Z-axis direction, further ensuring that each elastic arm 61 has good elastic deformation ability. It is worth noting that in the present solution and its related embodiments, by changing the position of each movable spring piece 51 for the elastic arm 61 to extend on one side, the second ends of each elastic arm 61 in the same elastic part can be arranged flush or staggered. The staggered arrangement can ensure that the movable spring piece 51 has a structure with uniform width distribution, thereby avoiding increased copper loss.

[0212] Example 3

[0213] The structure of Example 3 is basically the same as that of Example 2, except that Figure 30In this embodiment, along the Z-axis direction, the second connecting arm 66 corresponding to the movable spring piece 51 away from the driving part 34 is L-shaped, and the second ends of the elastic arms 61 of each elastic part are arranged at the same height along the Z-axis direction, and the first ends of the elastic arms 61 of each elastic part are connected as a whole, which is conducive to the convenience of molding each elastic part.

[0214] Example 4

[0215] Example 4 provides a magnetic latching relay, which has a structure substantially the same as that of Example 1, but differs from Example 1 in the following aspects:

[0216] First, the structure of the housing 11 is different. Figures 31-35 , Figure 31 FIG. 2 shows an exploded schematic diagram of a magnetic latching relay according to Example 3. Figures 32-35 A schematic diagram of the housing 11 is shown. The first partition plate 113 in Example 4 is further provided with two first slots 1132. The first partition plate 113 is not provided with a convex shaft, but with a plug-in hole. The housing 11 of Example 3 is not provided with a mounting seat 115, a reinforcing wall 116 and a fixing seat 119. The housing 11 of Example 3 is further provided with a second partition plate 120 perpendicular to the Z-axis direction on the basis of Example 1. The second partition plate 120 and the first partition plate 113 are arranged along the X-axis direction and the second partition plate 120 is closer to the second end of the housing 11 than the first partition plate 113. The second partition plate 120 can support the coil frame 21 and the auxiliary contact portion 300. The second partition plate 120 is further provided with a first limiting groove 1201 and a second limiting groove 1202 extending along the X-axis direction along the Y-axis direction. The length of the second limiting groove 1202 is longer than that of the first limiting groove 1201.

[0217] Second, the structure of the second cover 13 is different, see Figure 31 In this embodiment, the second cover 13 is only provided with a bottom wall 131 , but not with a second isolation plate 132 ;

[0218] Third, the structure of the fixing frame 14 is different, see Figure 31 In this embodiment, the fixing frame 14 is not provided with a limiting portion 141 and abutting portion 142, nor is a convex shaft provided, but an inserting hole is provided;

[0219] Fourth, the structure of the coil assembly 20 is different; in this embodiment, see Figure 31 The two yokes 24 are both L-shaped, the connecting section 241 extends along the X-axis direction, the magnetic drive end 242 and the connecting section 241 are at the same height along the Z-axis direction, and on the projection plane perpendicular to the X-axis direction, the projections of the two magnetic drive ends 242 and the coil winding 22 at least partially overlap; see Figure 36 , Figure 36The schematic diagram shows the coil assembly 20 installed in the housing 11. The two magnetic drive ends 242 are adapted to be inserted into the two first slots 1132 of the first partition 113 along the Z-axis direction and abut the bottoms of the first slots 1132. The signal terminal 01 passes through the second partition 120 and the bottom wall 131 and extends out of the accommodating member 10.

[0220] Fifth, the structure of the armature assembly 30 is different; see Figure 31 、 Figures 37-38 , Figure 37 It shows a schematic diagram of the armature assembly 30 being installed in the housing 11. Figure 38 The schematic diagram of the coil assembly 20 and the armature assembly 30 mounted in the housing 11 is shown. The armature assembly 30 is provided with a rotation shaft 332 at both ends along the Z-axis direction, which is suitable for inserting into the insertion holes of the fixing frame 14 and the first partition 113. The rotation axis of the armature assembly 30 is located between the two armatures 32 along the X-axis direction. The driving portion 34 is only provided with a downwardly opening accommodating groove 343 ( Figures 43-46 The auxiliary pushing portion 35 extends along the Z-axis and is provided with a pushing slot 351 extending along the X-axis. The pushing slot 351 opens downward and is through-connected at both ends. The auxiliary pushing portion 35 is located in the middle of the coil winding 22 along the Y-axis. The armature closer to the coil winding 22 is the second armature, and the armature closer to the coil winding is the first armature.

[0221] Sixth, the structure of the auxiliary contact portion 300 is different, see Figures 37-38 The auxiliary contact portion 300 and the coil winding 22 are arranged along the Z-axis direction and are located below the coil winding 22.

The location where the second end of the elastic portion is fixed to the swinging end is further away from the fixed end than the contact point between the movable contact 50 and the stationary contact 40.

[0223] The installation process of the relay in this embodiment is as follows:

On a projection plane perpendicular to the X-axis, the projection of the coil winding 22 at least partially overlaps with the projection of the contact portion 200. The rotation axis of the armature assembly 30 and the axis of the coil winding 22 are arranged along the X-axis.

[0233] See also Figures 48-52 , Figures 48-52 Schematic diagram showing the armature assembly in the first position and the second position. The working process of the relay of this embodiment is as follows:

[0234] When the signal terminal 01 receives the first pulse signal, the armature assembly 30 rotates from the second position to the first position, see Figure 48 The first attracting portion 321 attracts the first magnetic drive end 243, and the second attracting portion 322 attracts the second magnetic drive end 244; see Figures 49-50 , one driving part 34 drives the movable contact 52 at the first swing end to close with the fourth static contact 45 through the elastic member group 60, and the other driving part 34 drives the movable contact 52 at the second swing end to close with the second static contact 43 through the elastic member group 60, and the connecting terminal 02 corresponding to the second static contact 43 and the connecting terminal 02 corresponding to the fourth static contact 45 are connected in series through the first movable contact 55 and the second movable contact 56 and serve as one of the current input end and the current output end respectively, and the first movable contact 55 and the second movable contact 56 are connected in parallel; see Figure 50 , the auxiliary moving contact 72 and the auxiliary static contact 84 are closed along the Y-axis direction;

[0235] When the signal terminal 01 receives the second pulse signal, the armature assembly 30 rotates from the first position to the second position. Figure 51 , the first attracting portion 321 attracts the second magnetic drive end 244, and the second attracting portion 322 attracts the second magnetic drive end 244; see Figure 52 , one of the driving parts 34 drives the movable contact 52 at the first swing end to close with the first static contact 42 through the elastic member group 60, and the other driving part 34 drives the movable contact 52 at the second swing end to close with the third static contact 44 through the elastic member group 60, the connecting terminal 02 corresponding to the first static contact 42 is connected in series with the connecting terminal 02 corresponding to the second static contact 43 through the first movable contact 55, the connecting terminal 02 corresponding to the third static contact 44 is connected in series with the connecting terminal 02 corresponding to the fourth static contact 45, the connecting terminal 02 corresponding to the first static contact 42 is connected to the connecting terminal 02 corresponding to the fourth static contact 45 and together constitutes one of the current input end or the current output end, the connecting terminal 02 corresponding to the second static contact 43 is connected to the connecting terminal 02 corresponding to the third static contact 44 and together constitutes the other of the current input end or the current output end; see Figure 52 , the auxiliary moving contact 72 and the auxiliary static contact 84 are disconnected.

[0236] In this embodiment, on the projection plane perpendicular to the X-axis direction, the two magnetic drive ends 242 at least partially overlap with the projection of the coil winding 22. In this way, the coil winding 22 can be arranged in the same plane perpendicular to the Z-axis direction as the armature assembly 30, so that space is left on the side of the coil winding 22 facing the contact portion 200 along the Z-axis direction, which can be used for the subsequent installation of the auxiliary contact portion 300, thereby improving space utilization; the rotation axis is located between the two armatures 32 along the X-axis direction, so that the armature assembly 30 occupies less space along the X-axis direction.

[0237] In this embodiment, the setting of the auxiliary contact part 300 makes full use of the space on the side of the coil winding 22 away from the magnetic drive end 242 along the Z-axis direction, so that the auxiliary contact part 300 can be installed without increasing the volume of the accommodating part 10, thereby improving space utilization; in addition, after such design, the lead-out terminal 03 of the auxiliary contact part 300 and the terminal (weak current) of the coil winding 22 are both away from the terminal (strong current) of the contact part 200 along the X-axis direction, which is conducive to the isolation of the strong and weak current terminals.

[0238] In this embodiment, the auxiliary pushing portion 35 extends along the Z-axis direction. Compared with extending along the X-axis direction or the Y-axis direction, the auxiliary pushing portion 35 basically does not occupy the space of the coil winding 22 along the Z-axis direction toward the contact portion 200, so that the space can be used to arrange the auxiliary contact portion 300. The auxiliary moving contact 70 includes an auxiliary moving spring 71 whose extension direction is perpendicular to the Z-axis direction. The auxiliary moving spring 71 is provided with an auxiliary moving contact 72. The auxiliary static contact 80 includes an auxiliary static spring 83 extending along the X-axis direction. The auxiliary static spring 83 is provided with an auxiliary contact portion 82. The auxiliary moving contact 72 is suitable for closing or disconnecting along the Y-axis direction and the auxiliary contact portion 82, so that the auxiliary contact portion 300 as a whole occupies a small space in the Z-axis direction and the Y-axis direction; in addition, compared with the structure in which the auxiliary contact portion 300 is a standard part of a micro switch, the auxiliary contact portion 300 of this structure can adjust the position of the pin as needed, which is more practical.

[0239] In this embodiment, the auxiliary movable spring 71 is in point contact or line contact with the two groove walls of the pushing groove 351, which reduces the friction between the auxiliary movable spring 71 and the auxiliary pushing part 35, avoids damage after long-term use, and improves the service life.

[0240] In this embodiment, the auxiliary contact portion 300 is located in the middle of the coil winding 22 along the Y-axis direction, creating conditions for the lead terminal 03 of the auxiliary contact portion 300 and the signal terminal 01 of the coil assembly 20 to be away from each other; the auxiliary pushing portion 35 is located in the middle of the coil winding 22 along the Y-axis direction. Compared with the auxiliary pushing portion 35 being located at other eccentric positions, the angle formed by the auxiliary movable spring 71 and the groove wall of the pushing groove 351 is smaller. Therefore, when the auxiliary pushing portion 35 rotates, the relative movement stroke between the auxiliary movable spring 71 and the groove wall of the pushing groove 351 is smaller, the friction force is smaller, and the movable end of the movable spring 51 is not easily stuck when swinging.

[0241] In this embodiment, the second partition 120 is suitable for supporting the coil assembly 20, the auxiliary moving contact 70 and the auxiliary static contact 80, so that the length of the coil assembly 20 along the Z-axis direction does not need to be too long, and the length of the auxiliary pushing portion 35 along the Z-axis direction does not need to be too long, thereby ensuring the support stability of the coil assembly 20 and the support stability of the auxiliary contact portion 300.

[0242] In this embodiment, the fixed portion is fixedly connected to the swinging end of the movable contact 50 and integrally connected to the second end of the elastic portion. This makes molding the movable contact 50 easier than molding the elastic portion directly onto the movable contact 50. The fixed portion is fixedly connected to the movable contact 50 at the location of the movable contact 52. Compared to other locations, the elastic portion directly applies greater contact pressure to the movable contact 52, resulting in more stable contact between the movable contact 52 and the stationary contact 41.

[0243] In this embodiment, the elastic portion is an elastic arm 61, and the fixed portion is a first connecting wall extending along the Z-axis direction. The elastic arm 61 and the first connecting wall 65 are arranged along the extension direction of the dynamic contact 50. The first connecting wall 65 is fixedly connected to the swinging end of each dynamic spring piece 51. The second end of the elastic arm 61 is suitable for driving each dynamic spring piece 51, so that one elastic arm 61 can apply contact pressure to multiple dynamic contacts 52 on the other side of the dynamic contact piece 50. The structure is simple and the cost is low.
