In some environments where connection with a PCB board is required, in the relay, the coil winding and the contact part are usually compactly arranged on both sides of the armature assembly's attraction direction. In this way, the terminals of the coil winding and the contact part can be easily led out from the first side wall of the container to connect with the PCB board, while achieving strong and weak electrical isolation, pushing the card close to one side of the first side wall to make the moving and static contacts of the contact part closer to the first side wall and save copper loss. Due to the compact internal space, if it is necessary to monitor the use status of the relay, the method generally adopted is to set a sampling pin on the connection terminal of the contact part, but the signal collected by the sampling pin requires the terminal product to set a conversion module to convert it into a recognizable signal, which increases the complexity and cost of the terminal product, so the market response is poor.

[0005] 2. The auxiliary monitoring switch is arranged on a side away from the first side wall, and its lead terminal extends from the bottom wall or the top wall, and then extends from the signal line to the first side wall.

[0036] 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:

[0037] The applicant has learned through continuous observation, experimentation and research that the reason for the technical problem in the prior art scheme that "in the prior art scheme one, after the relay is provided with an auxiliary monitoring switch, the relay is large in size, inconvenient to assemble, the structure of the armature assembly is unstable, the structure of the accommodating part is relatively complex, the molding is difficult, and the bottom wall is prone to deformation" is that the auxiliary monitoring switch is arranged in the gap between the armature assembly and the bottom wall, which increases the space of the relay in the direction of the rotating axis of the armature assembly, thereby increasing the volume of the relay, and also makes a larger spacing between the rotating shaft of the armature assembly and the bottom wall, so that the rotating shaft of the armature assembly needs to be set longer and is prone to deformation, thereby reducing the stability of the armature assembly, the auxiliary monitoring switch is installed from the bottom surface, and the contact part and the magnetic circuit part are installed from the top surface, and the installation directions are different, so it is inconvenient to assemble, and openings need to be set on both the bottom wall and the first side wall, so the overall strength of the accommodating part is weak and easy to deform, and the openings at different positions will also make the mold design of the accommodating part more difficult, and the accommodating part is difficult to mold, and in this scheme, the lead terminal has a long extension length, large consumables and is inconvenient to connect with the PCB board. The reason for the technical problem of "after the auxiliary monitoring switch is set for the relay in the second prior art solution, it is inconvenient to assemble, the structure of the container is relatively complex, it is difficult to mold and it is easy to deform" is that the lead terminal of the auxiliary monitoring switch extends from the top wall of the container and then connected to the signal line, which is inconvenient to assemble and costly. Since a positioning groove needs to be provided on the top wall or the bottom wall, the structure of the container is relatively complex, the mold design is more difficult, the container is difficult to mold, and the top wall or the bottom wall is easy to deform. In addition, in this solution, the auxiliary monitoring switch is far away from the first side wall, so it is inconvenient to connect with the PCB board.

[0038] In technical solution one and its preferred embodiments, the contact portion is suitable for being driven by the armature assembly to be switched on and off along the X-axis direction. It can be seen that the contact portion extends along the Y-axis direction, and the coil winding and the contact portion are arranged on both sides of the armature assembly along the X-axis direction, with a compact arrangement, which is beneficial to reducing the volume of the relay; the coil winding and the contact portion extend along the Y-axis direction, and on this basis, each signal terminal and each connecting terminal also extend from the first side wall along the Y-axis direction, and the extension path is short, which can avoid the complexity of the internal circuit of the relay and the weak circuit strength; since the first through-slot, the second through-slot and the third through-slot are all opened on the end surface of the opening end of the base, each connecting terminal extends from the first through-slot along the Y-axis direction, and each signal terminal and each connecting terminal extend from the first through-slot along the Y-axis direction. The terminals of the relay all extend from the third through-slot along the Y-axis direction, and the lead-out terminals all extend from the second through-slot along the Y-axis direction. Therefore, the contact part, the auxiliary monitoring switch and the coil assembly can be placed in the base from the open end of the base when installed, which improves the convenience of installation. As a result, the second through-slot and the third through-slot on the first side wall do not need to be opened very long along the Z-axis direction, which reduces the weakening of the strength of the first side wall, so that the strength of the first side wall is minimal when the auxiliary monitoring switch is added to the relay, thereby ensuring the strength of the first side wall. In addition, it is also unnecessary to open through-slots on other walls of the base, thereby improving the overall strength of the base and reducing the difficulty of forming the container. More preferably, it is also conducive to the relay being conveniently connected to the PCB board along the Y-axis direction. The auxiliary monitoring switch is arranged between the armature assembly and the first side wall along the Y-axis direction and close to the yoke iron along the X-axis direction, making full use of the gap between the armature assembly and the first side wall and the space around the yoke iron, and installing the auxiliary monitoring switch without increasing the volume of the container, thereby reducing the volume of the container. Among them, the first side wall is sequentially provided with a first through groove, a second through groove and a third through groove along the X-axis direction, so that the lead terminal is located between the connection terminal and the signal terminal along the X-axis direction, which is conducive to realizing the electrical isolation between the weak-current terminal of the relay (including the signal terminal and the lead terminal) and the strong-current terminal of the relay (here mainly refers to the connection terminal of the contact part). Therefore, compared with the prior art scheme one and the prior art scheme two, the present technical scheme has less difficulty in molding the accommodating part, simple molding of the accommodating part, and a small size of the relay. Compared with the prior art scheme one, there is not much gap between the rotating shaft of the armature assembly and the bottom wall, and the rotating shaft of the armature assembly does not need to be set longer, is not easy to deform, and has a stable structure of the armature assembly. In addition, the auxiliary monitoring switch in the present technical scheme occupies less space than the auxiliary monitoring switch standard part, and the position of the terminal of the auxiliary monitoring switch can be adjusted as needed, and the structural design is simpler. In this technical solution, the connecting terminals, signal terminals and lead terminals all extend along the Y-axis direction. On the one hand, it eliminates the need for complex bending of the terminals, reduces molding difficulty and material costs, and increases their service life. On the other hand, it makes the wiring path on the PCB board simpler.

[0039] In technical solution two and its preferred embodiments, the number of first through grooves is equal to and corresponds to the number of connecting terminals, the number of second through grooves is relative to and corresponds to the number of lead terminals, and the number of third through grooves is equal to and corresponds to the number of signal terminals. Compared with the solution of "each connecting terminal penetrates the same first through groove, each lead terminal penetrates the same second through groove, and each signal terminal penetrates the same third through groove", the first through groove, the second through groove and the third through groove are smaller, which reduces the impact on the strength of the first side wall and can better position the corresponding terminals.

[0040] In technical solution three and its preferred embodiments, each lead terminal is arranged along the X-axis direction and is close to the opening end of the base; each signal terminal is arranged along the X-axis direction and is close to the opening end of the base. Compared with the solution in which the lead terminal and the opening end of the base and the signal terminal and the opening end of the base have a larger distance, the length of the second through groove and the third through groove in the Z-axis direction can be reduced, thereby further weakening the influence on the strength of the first side wall, and it is beneficial to limit the lead terminal and the signal terminal in the Z-axis direction through the outer shell and the corresponding through groove bottom.

[0041] In technical solution four and its preferred embodiments, since the yoke is usually fixed to the end face of the coil winding and is fixedly inserted into the accommodating part together with the coil winding, in this solution, since the auxiliary monitoring switch is arranged close to the yoke along the X-axis direction, the auxiliary static contact is directly fixed to the yoke, and the auxiliary static contact can be installed and positioned simultaneously when the yoke is installed, avoiding the need to install the auxiliary static contact again. The assembly is simple, thereby solving the problem of difficult assembly and positioning of tiny parts. In addition, the problem of scraping that is prone to occur when the auxiliary static contact is installed with the base can be avoided. More preferably, the stability of the yoke and the coil body on the base is also utilized, so that the auxiliary static contact is directly supported by the yoke to obtain strength and stability, so that there is no need to form a mounting portion on the accommodating part, making the structure of the accommodating part simple, easy to form and saving materials. In addition, it is also beneficial to reduce the volume of the accommodating part and the miniaturized design of the relay to better meet usage requirements and reduce costs. In the present technical solution, since it is only necessary to install the auxiliary moving contact on the base, the situation in which two installation positions are originally required to be provided on the container for installing the auxiliary static contact and the auxiliary moving contact respectively is changed to only providing one installation position, and the installation of the auxiliary moving contact only needs to consider the ability to be reliably separated from the auxiliary moving contact and ensure that the auxiliary moving contact can avoid other structures of the armature assembly and the coil assembly. Therefore, the space used for the overall installation of the auxiliary monitoring switch is effectively reduced without increasing the volume of the container, thereby providing favorable conditions for installing the auxiliary monitoring switch in a compact space without increasing the volume of the container.

[0042] In technical solution five and its preferred embodiment, a reinforcement portion is further provided in the base, and the reinforcement portion is integrally connected to the first side wall and the bottom wall, which not only strengthens the strength of the first side wall, but also strengthens the strength of the bottom wall, thereby improving the overall strength of the base.

[0043] In technical solution six and its preferred embodiment, the reinforcing part is provided with a first supporting surface and a second supporting surface perpendicular to the Z-axis direction along the X-axis direction, and the first supporting surface and the second supporting surface are respectively suitable for supporting the auxiliary moving contact and the auxiliary static contact, thereby improving the stability of the auxiliary monitoring switch.

[0044] In technical solution seven and its preferred embodiment, the first side of the auxiliary static contact part is used to contact with the auxiliary moving contact, and its second side opposite to each other is abutted against the yoke. When the auxiliary moving contact contacts the auxiliary static contact part, the auxiliary static contact part is supported by the yoke, which further makes the auxiliary static contact part have good stability in the contact direction of the auxiliary moving contact, so that the contact between the auxiliary moving contact and the auxiliary static contact part is reliable.

[0045] In technical solution eight and its preferred embodiment, the auxiliary static contact is abutted against and fixed to the side of the yoke facing away from the coil winding along the X-axis direction. Compared with being fixed to the side of the yoke facing the coil winding, the auxiliary static contact can more easily avoid the coil winding, and the distance between the coil winding and the armature assembly (along the X-axis direction) does not need to be too large, thereby reducing the space occupied by the relay in the X-axis direction.

[0046] In technical solution nine and its preferred embodiment, the yoke is provided with a magnetic drive section extending perpendicular to the X-axis direction, and the auxiliary static contact is fixedly connected to the side of the magnetic drive section away from the coil winding. The advantage of the magnetic drive section having a large surface area is utilized to help improve the connection strength and stability of the auxiliary static contact after being fixed to the magnetic drive section. Furthermore, compared with the form in which the auxiliary static contact is fixed to the connection section of the yoke, the auxiliary monitoring switch occupies less space in the Y-axis direction. The auxiliary moving contact is suitable for closing or disconnecting with the auxiliary static contact along the X-axis direction, so that when the auxiliary moving contact and the auxiliary static contact are closed, the auxiliary static contact can be supported by the magnetic drive section, and the structure is more stable.

[0047] In technical solution ten and its preferred embodiment, the auxiliary static contact part is in the shape of a flat sheet parallel to the magnetic drive section, which is beneficial to reduce the space occupied by the auxiliary static contact part in the X-axis direction, so as to avoid interference with the movement of the armature assembly.

[0048] In technical solution eleven and its preferred embodiments, the connection between the magnetic drive section and the connecting section has an arc transition surface, and the position where the auxiliary static contact part is fixed to the magnetic drive section avoids the arc transition surface, so that the auxiliary static contact part and the yoke iron have a larger connection area, thereby improving the fixing strength between the auxiliary static contact part and the yoke iron.

[0049] In technical solution twelve and its preferred embodiments, the width direction of the yoke extends along the Z-axis direction; the position where the auxiliary static contact is fixed to the magnetic drive section is close to the first end of the yoke away from the bottom wall. Compared with being set close to the middle part of the yoke, the auxiliary static contact is easier to avoid the armature assembly in the Z-axis direction, and it is also easier to realize the fixing operation of the auxiliary static contact and the yoke.

[0050] In technical solution thirteen and its preferred embodiments, at the first end of the yoke, the magnetic drive section is provided with a protrusion protruding relative to the connecting section along the Z-axis direction, and the auxiliary static contact portion is at least partially fixed to the protrusion. On the one hand, it makes it easier for the auxiliary static contact to avoid the armature assembly in the Z-axis direction. On the other hand, it makes it easier for the fixed position to avoid the arc transition surface of the yoke, so that the connection between the auxiliary static contact and the yoke is more stable. In addition, the auxiliary static contact and the yoke can have a larger connection area, thereby improving the fixing strength.

[0051] In technical solution fourteen and its preferred embodiments, an avoidance gap suitable for avoiding the armature assembly is formed between the first connecting part and the second connecting part; the second connecting part is closer to the bottom wall than the first connecting part; along the Y-axis direction, the second connecting part is closer to the arc transition surface of the yoke than the first connecting part; the first connecting part is fixed to the yoke; the auxiliary static contact is arranged on the second connecting part, on the one hand, making it easier for the auxiliary static contact to avoid the armature assembly in the Y-axis direction and the Z-axis direction, and on the other hand, making the first connecting part farther away from the arc transition surface of the yoke, thereby improving the connection stability between the first connecting part and the yoke; in addition, setting the second connecting part closer to the arc transition surface is conducive to avoiding interference of the second connecting part with the movement of the armature assembly.

[0052] In technical solution fifteen and its preferred embodiments, the auxiliary static contact is also provided with a static lead-out terminal and a bending portion, which extends along the X-axis direction, is connected between the first connecting portion and the static lead-out terminal and is located on one side of the connecting section along the Z-axis direction. On the one hand, the space on one side of the connecting section along the Z-axis direction is fully utilized to avoid the auxiliary static contact from expanding the occupied space of the relay in the Z-axis direction; on the other hand, the static lead-out terminal is close to the coil assembly, which is more conducive to achieving electrical isolation between the weak-current terminals of the relay (including the terminals of the coil assembly and the terminals of the auxiliary monitoring switch) and the strong-current terminals of the relay (mainly referring to the connecting terminals of the contact part below). In addition, the static lead-out terminal is connected to the bending portion, which is conducive to saving the length of the bending portion, saving consumables and costs.

[0053] In technical solution sixteen and its preferred embodiments, when the auxiliary moving contact contacts the auxiliary static contact, the auxiliary static contact has an electrical path, and the position where the auxiliary static contact is fixed to the magnetic drive segment is outside the electrical path. When the auxiliary monitoring switch is closed, the current does not enter the yoke through the position where the auxiliary static contact is fixed to the magnetic drive segment. Therefore, there is no need to set an insulating structure between the auxiliary static contact and the magnetic drive segment, thereby avoiding the current of the auxiliary monitoring switch from affecting the magnetic circuit in the yoke and reducing the complexity of the structure.

[0054] In technical solution seventeen and its preferred embodiment, the auxiliary static contact is also provided with a static lead-out terminal and a bending portion, which extends along the X-axis direction, is connected between the auxiliary static contact portion and the static lead-out terminal and is located on one side of the connecting section along the Z-axis direction. On the one hand, the space on one side of the connecting section along the Z-axis direction is fully utilized to avoid the auxiliary static contact from expanding the occupied space of the relay in the Z-axis direction; on the other hand, the static lead-out terminal is close to the coil assembly, which is more conducive to achieving electrical isolation between the weak-current terminals of the relay (including the terminals of the coil assembly and the terminals of the auxiliary monitoring switch) and the strong-current terminals of the relay (here mainly referring to the connecting terminals of the contact part). In addition, the static lead-out terminal is connected to the bending portion, which is conducive to saving the length of the bending portion, saving consumables and costs.

[0055] In technical solution eighteen and its preferred embodiment, the auxiliary static contact is located between the position where the auxiliary static contact part is fixed to the magnetic drive segment and the arc transition surface along the Y-axis direction, which is conducive to realizing that the position where the auxiliary static contact part is fixed to the magnetic drive segment is outside the electrical path, and makes the fixed position farther away from the arc transition surface of the yoke iron, and the connection between the auxiliary static contact part and the yoke iron is more stable.

[0056] In technical solution nineteen and its preferred embodiments, a mounting groove opening away from the coil winding and a riveted portion protruding from the mounting groove are stamped out on the side of the magnetic drive section of the yoke iron facing away from the coil winding. The auxiliary static contact is installed in the mounting groove and is provided with a riveted hole cooperating with the riveted portion. The stamping process allows the riveted portion to have a longer length in the X-axis direction, thereby also allowing the auxiliary static contact to have a larger thickness, and when applied to a relay, it occupies less space in the X-axis direction.

[0057] In technical solution 20 and its preferred embodiment, the auxiliary static contact part is riveted to the yoke iron, which makes the process simpler and the structure more stable.

[0058] In technical solution twenty-one and its preferred embodiment, the rivet hole is a countersunk hole, and the riveted part does not protrude from the rivet hole, which is more conducive to reducing the space occupied by the auxiliary static contact part in the X-axis direction.

[0059] In Technical Solution Twenty-two and its preferred embodiments, the reinforcing part is provided with a first limiting groove, and the auxiliary moving contact is provided with a fixed part and a swinging part, and the fixed part is fixedly inserted in the first limiting groove along the Z-axis direction, so that the reinforcing part can not only strengthen the overall strength of the base, but also limit the fixed part of the auxiliary moving contact, thereby eliminating the need to set a separate positioning structure for the auxiliary moving contact, thereby reducing the difficulty of forming the base.

[0060] In technical solution twenty-three and its preferred embodiment, the reinforcing portion also cooperates with the first side wall to form a second limiting groove extending along the X-axis direction, and the auxiliary movable contact is also provided with a movable lead-out portion, which connects the fixed portion and the movable lead-out terminal and is limited in the second limiting groove along the Y-axis direction, which is conducive to the extension of the movable lead-out terminal along the Y-axis direction, and thereby makes the auxiliary movable contact and the base have more matching structures, which is more conducive to improving the stability of the movable lead-out terminal. The movable lead-out portion is located on the side of the fixed portion facing the auxiliary static contact, so that the movable lead-out terminal can be close to the static lead-out terminal, which is conducive to improving the electrical isolation effect between it and the connection terminal.

[0061] In technical solution twenty-four and its preferred embodiment, the moving lead-out part is in the shape of a flat sheet perpendicular to the Y-axis direction, which is beneficial to reducing the space occupied by the moving lead-out part in the Y-axis direction, thereby providing favorable conditions for installing the auxiliary monitoring switch in a compact space.

[0062] In technical solution twenty-five and its preferred embodiment, the auxiliary moving contact is provided with an auxiliary moving spring extending in the Z-axis direction. Compared with the auxiliary moving spring extending in the Y-axis direction, the auxiliary monitoring switch occupies less space in the Y-axis direction, and because the fixed portion is fixedly inserted in the first limiting groove, the length between the swing portion and the fixed end of the auxiliary moving spring is longer, which is more conducive to reducing the stress concentration phenomenon of the auxiliary moving spring and improving the service life. The auxiliary moving spring is a sheet-like structure with the thickness direction extending in the X-axis direction, which is conducive to reducing the space occupied by the auxiliary moving spring in the X-axis direction, and further conducive to installing the auxiliary moving contact in a compact space.

[0063] In technical solution twenty-six and its preferred embodiment, one end of the pushing part is fixedly connected to the swinging part, and the other end is suitable for being driven by the armature assembly. The pushing part is arranged close to the swinging part, which is beneficial to ensure stable contact between the auxiliary moving contact and the auxiliary static contact.

[0064] In technical solution twenty-seven and its preferred embodiment, the auxiliary static contact is provided with at least two auxiliary static contacts, and each auxiliary static contact is located at the same height along the Z-axis direction; the auxiliary moving spring is provided with contact branches equal to and corresponding to the auxiliary static contacts, one end of each contact branch is fixed to the fixed part, and the other end is provided with an auxiliary moving contact suitable for abutting the auxiliary static contact; each contact branch forms a swinging part at one end away from the fixed part. On the one hand, the provision of multiple auxiliary moving and static contacts can improve the connection reliability of the auxiliary monitoring switch, and is also beneficial to the processing of the auxiliary moving contact and the auxiliary static contact. On the other hand, it is also beneficial to the deformation of the auxiliary moving contact along the X-axis direction, thereby improving the connection reliability and extending the service life; each auxiliary static contact is located at the same height along the Z-axis direction so that the contact pressure of each auxiliary moving contact and each auxiliary static contact is consistent.

[0065] In technical solution twenty-eight and its preferred embodiments, under normal circumstances, if the armature assembly drives the moving contact to move by driving an independent pushing card, then the area on the side of the yoke facing the contact part along the X-axis direction is usually used as the activity space of the pushing card. If it is necessary to install an auxiliary monitoring switch on one side of the armature along the Y-axis direction, it is necessary to lead out a swing arm from the armature assembly to push the auxiliary monitoring switch, and the swing arm also needs to bypass the armature in the armature assembly, resulting in a more complex structure, large consumables and large volume. In this technical solution, the driving member is provided with an integrally formed driving part and an auxiliary pushing part, the driving member and the insulating member are integrally formed, and the insulating member is fixedly connected to the permanent magnet member. Through reasonable design and processing, the driving part can avoid the space for installing the auxiliary monitoring switch, and at the same time, the small-structured auxiliary pushing part is used to drive the auxiliary moving contact in the auxiliary monitoring switch to move. The structure is simple, the consumables are small, the molding is good, and there is no need to increase the volume of the relay. In the present technical solution, the driving part and the auxiliary pushing part are integrally arranged on the driving member, which has a simple structure, is easy to form and is conducive to reducing production costs. In addition, the driving part and the auxiliary pushing part are relatively stable relative to the armature assembly, thereby reducing the jitter of the moving contact and the auxiliary moving contact during disconnection, avoiding affecting the arc burning characteristics of the disconnecting arc, and reducing hazards such as contact erosion and uncontrolled arc erosion of other components.

The magnetic circuit part 100 (except the signal terminal 01 hereinafter) is basically accommodated in the second groove 115 . The magnetic circuit part 100 includes a coil assembly 20 and an armature assembly 30 .

Figure 1 and Fig.11The coil assembly 20 is placed in the second slot 115 and supported on the bottom wall 111 of the second slot 115. The coil assembly 20 includes a coil frame 21, a coil winding 22, an iron core and two yokes 23. The coil frame 21 is fixedly connected to the second slot 115. The coil frame 21 extends along the Y-axis direction and is provided with a center hole extending along the Y-axis direction (not shown in the figure). The coil frame 21 is provided with retaining walls 211 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 211. Therefore, the coil winding 22 also extends along the Y-axis direction and is fixed relative to the base 11. In this embodiment, the coil winding 22 is fixedly connected to the base 11. The coil winding 22 has at least two signal terminals 01, which are fixed to the retaining wall 211 of the coil frame 21 and penetrate the first side wall 112 along the Y-axis direction.

The iron core extends along the Y-axis direction and is inserted into the center hole of the coil frame 21. The two yokes 23 are respectively fixed to the two ends of the iron core, that is, the two yokes 23 are fixed to the end faces of the coil winding 22, see Fig.11 The width direction of the yoke 23 extends along the Z-axis direction.

The two magnetic drive sections 231 are arranged along the Y-axis direction, and the two magnetic drive sections 231 are respectively the first magnetic drive section 234 and the second magnetic drive section 235.

[0102] Figure 1 The structure of the armature assembly 30 and the insulating member 34 is shown. Figure 4 and Figure 7 In the embodiment, the armature assembly 30 is arranged on one side of the coil winding 22 along the X-axis direction and is adapted to rotate around a rotation axis extending along the Z-axis direction in response to a change in polarity of the yoke 23. 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 at intervals along the X-axis direction.

[0103] like Figure 1As shown, in this embodiment, the armature assembly 30 includes a permanent magnet (not shown in the figure), two armatures 31 and an insulating member 34. The permanent magnet is formed by a magnetized magnetic steel. In other embodiments, the permanent magnet can also be made of other permanent magnetic materials, such as a neodymium iron boron permanent magnet. The permanent magnet has two magnetic poles with fixed polarity, and the polarities of the two magnetic poles are opposite. The two armatures 31 are respectively fixed to the two magnetic poles of the permanent magnet, and each armature 31 is respectively provided with two suction parts suitable for suction with the magnetic drive segment 231. When the magnetic circuit part 100 is in the magnetic holding state, the coil winding 22 is no longer energized, and the two armatures 31 respectively have a suction part to suction the corresponding magnetic drive segment 231 to form a closed magnetic circuit passing through the two magnetic drive segments 231. In this embodiment, the two armatures 31 are respectively a first armature 32 and a second armature 33. Two first suction parts 321 are respectively provided at both ends of the length direction of the first armature 32; two second suction parts 331 are respectively provided at both ends of the length direction of the second armature 33. The length of the first armature 32 is longer than the length of the second armature 33 .

[0104] The insulating member 34 is fixedly connected to the permanent magnet member and the two armatures 31. For example, the insulating member 34 can be an injection molded member. The insulating member 34 wraps the two armatures 31 and the permanent magnet member to form a whole. Both ends of the first armature 32 and the second armature 33 are located outside the insulating member 34. The insulating member 34 has protruding plug shafts 341 extending along the Z-axis direction at positions close to the first armature 32 on both sides of the Z-axis direction. The two plug shafts 341 are coaxial and form the rotation axis of the armature assembly 30. Therefore, the rotation axis is closer to the side where the first armature 32 is located along the width direction of the armature assembly 30; the rotation axis is centrally arranged along the length direction of the armature assembly 30.

[0105] See also Fig.10 , Fig.10 The structure of the driving member 80 is shown in the figure. The driving member 80 is integrally formed with the insulating member 34 and is located on the side of the first armature 32 away from the second armature 33. The driving member 80 is provided with an integrally formed driving portion 81 and an auxiliary pushing portion 82. The driving portion 81 and the auxiliary pushing portion 82 are both located on one side of the length direction of the armature assembly 30. Fig.10 In the embodiment, the driving portion 81 and the auxiliary push portion 82 are respectively located at the two ends of the height direction of the armature assembly 30, and the driving portion 81 is lower than the auxiliary push portion 82. The driving portion 81 is provided with a driving groove 811 opening upward, and the extending direction of the driving groove 811 is parallel to the length direction of the armature assembly 30, and the lengths of the two groove walls of the driving groove 811 are inconsistent. Fig.10In the embodiment, the width of the two groove walls of the driving groove 811 at the position for contacting the movable spring piece 41 described below is smaller than the width of other positions of the driving portion 81. The auxiliary pushing portion 82 is provided with a pushing groove 821 with an opening toward the insulating member 34. It should be understood that the openings are provided on the driving groove 811 and the pushing groove 821 to facilitate the insertion of the movable spring piece 41 and the auxiliary movable contact member 70 described below, respectively. In other embodiments, the driving groove 811 and the pushing groove 821 may also not have openings. Figure 1 and Fig.10 In the figure, the insulating member 34 is only the part that wraps the permanent magnet member, and the rest of the parts are the driving member 80.

[0106] The contact portion 200, except for the connection terminal 02 described below, is accommodated in the first groove 114. Figure 4 and Figure 7 In the embodiment, the contact portion 200 is arranged on the side of the armature assembly 30 away from the coil winding 22 along the X-axis direction and is suitable for being driven by the armature assembly 30 to be switched on and off along the X-axis direction. It has at least two connection terminals 02 for bearing current input or output. In this embodiment, the contact portion 200 is suitable for being driven by the driving part 81 to be switched on and off. The number of the connection terminals 02 is two and corresponds to the two first through slots 1121 one by one, that is, the number of the connection terminals 02 and the first through slots 1121 are equal and correspond one by one, and the two connection terminals 02 are respectively suitable for extending from the two first through slots 1121 along the Y-axis direction. Specifically, see also Figure 1 The contact portion 200 includes a moving contact 40 and a stationary contact 50, and the moving contact 40 includes a moving spring piece 41 and a moving spring lead-out piece 42; one end of the moving spring piece 41 along its length direction is fixed to the first positioning groove 1141, and the other end is suitable for cooperating with the driving part 81 and is provided with a moving contact point 411, and the moving contact point 411 is suitable for being driven by the driving part 81 to close or disconnect with the stationary contact 50. The movable spring lead-out piece 42 avoids the movable contact 411 and is fixedly connected to the movable spring piece 41 and passes through one of the first through grooves 1121 of the first side wall 112 to form one of the connecting terminals 02. The movable spring lead-out piece 42 is provided with an avoidance groove 421 opening downward near the movable contact 411. In this embodiment, the movable spring lead-out piece 42 is fixedly connected to the fixed end of the movable spring piece 41 and cooperates with the first positioning groove 1141 of the base 11 to be fixed in the accommodating member 10. It is located on the side of the movable contact 40 away from the static contact 50. When current is passed, the current direction of the movable spring lead-out piece 42 is opposite to the current direction of the movable contact 40. The Ampere force formed on the movable contact 40 helps to increase the contact pressure between the movable contact 40 and the static contact 50, thereby helping to avoid the movable contact 411 and the static contact 51 described below from being disconnected and exploding due to electric repulsion when a large fault current occurs.

[0107] The static contact 50 extends along the Y-axis direction and is fixed in the matching groove 1142. The static contact 50 is provided with a static contact 51 and another connecting terminal 02 penetrating another first through groove 1121 of the first side wall 112; the moving contact 411 and the static contact 51 are suitable for closing or opening along the X-axis direction.

[0108] See also Figure 1 , Figure 4 and Figure 7 The auxiliary monitoring switch 300 is arranged between the armature assembly 30 and the first side wall 112 along the Y-axis direction and close to the yoke 23 along the X-axis direction. It is suitable for being driven by the armature assembly 30 to be turned on and off, and has a lead terminal for external connection; the lead terminal extends from the second through-slot 1122 along the Y-axis direction. In the present embodiment, the number of the lead terminals is two, and the two lead terminals correspond one-to-one to the two second through-slots 1122, that is, the number of the lead terminals and the second through-slots 1122 is equal and one-to-one corresponding, and the two lead terminals are respectively suitable for extending from the two second through-slots 1122 along the Y-axis direction and are both close to the opening end of the base 11.

[0109] Specifically, the auxiliary monitoring switch 300 includes an auxiliary static contact 60 and an auxiliary moving contact 70. In this embodiment, the auxiliary static contact 60 is fixed to the yoke 23 near the first side wall 112, and it and the auxiliary moving contact 70 each have a lead terminal. The auxiliary moving contact 70 is adapted to be driven by the armature assembly 30 to move to contact or move away from the auxiliary static contact 60 to turn the auxiliary monitoring switch 300 on or off.

[0110] In this embodiment, see Fig.12 , Fig.12The figure shows the matching schematic diagram of the auxiliary static contact 60 and the yoke 23. The auxiliary static contact 60 is provided with an auxiliary static contact portion 61, a bending portion 62 and a static lead-out terminal 03. The auxiliary static contact portion 61 is provided with a first side and a second side which are opposite to each other. The first side is used to contact the auxiliary moving contact 70, and the second side is abutted against the yoke 23. The auxiliary static contact portion 61 is abutted against and fixed to the side of the yoke 23 which is opposite to the coil winding 22 along the X-axis direction. Specifically, the auxiliary static contact portion 61 is in the shape of a flat sheet which is parallel to and abuts against the magnetic drive section 231. One side surface of the auxiliary static contact portion 61 is abutted against the magnetic drive section 231 and is provided with a first connecting portion 611 and a second connecting portion 612 which are connected as one body along the Z-axis direction. An avoidance gap 614 which is suitable for avoiding the armature assembly 30 is formed between the first connecting portion 611 and the second connecting portion 612. Along the Z-axis direction, the second connecting portion 612 is farther away from the first end of the yoke 23 than the first connecting portion 611, and the yoke 23 is located along its width. The first end of the direction is away from the bottom wall 111, that is, the second connection part 612 is closer to the bottom wall 111 than the first connection part 611; along the Y-axis direction, the second connection part 612 is closer to the arc transition surface 233 of the yoke 23 than the first connection part 611; the first connection part 611 is fixedly connected to the yoke 23; at least two auxiliary static contacts 613 are provided on the side of the second connection part 612 that is away from the magnetic drive section 231, and each auxiliary static contact 613 is arranged along the Y-axis direction and is at the same height along the Z-axis direction. Therefore, the position where the auxiliary static contact part 61 is fixedly connected to the magnetic drive section 231 avoids the arc transition surface 233. And in this embodiment, the position where the auxiliary static contact part 61 is fixedly connected to the magnetic drive section 231 is arranged close to the first end of the yoke 23 along the Z-axis direction and is at least partially fixedly connected to the protrusion 2311. The bending portion 62 extends along the X-axis direction, is connected between the first connecting portion 611 and the static lead-out terminal 03, and is located on one side of the connecting section 232 along the Z-axis direction. In a specific implementation, the auxiliary static contact portion 61 is riveted to the yoke 23. During riveting, the auxiliary static contact portion 61 is provided with a rivet hole 6111, and the yoke 23 is provided with a rivet portion 2351 that matches the rivet hole 6111; the rivet hole 6111 is a countersunk hole, and the rivet portion 2351 does not protrude from the rivet hole 6111. However, it should be understood that in other embodiments, the auxiliary static contact 60 can also be fixed to the yoke 23 by other means, such as welding, bonding, etc.

[0111] See also Figure 13-14 , Figure 13-14Schematic diagrams of the auxiliary monitoring switch 300 are shown in the figures. The auxiliary moving contact 70 includes an auxiliary moving spring member 71 and a lead-out member 72. The auxiliary moving spring member 71 extends along the Z-axis direction. The auxiliary moving spring member 71 is a sheet-like structure whose thickness direction extends along the X-axis direction. One end of the auxiliary moving spring member 71 along the Z-axis direction is fixedly connected to the bottom wall 111 of the accommodating member 10 mentioned above to form a fixed end, and the other end forms a swinging portion 711. In this embodiment, the auxiliary moving spring member 71 is provided with contact branches 712 that are equal in number to and correspond to the auxiliary static contacts 613. One end of each contact branch 712 is fixedly connected to the fixed portion 73, and the other end is provided with an auxiliary moving contact 7111 suitable for abutting against the auxiliary static contact 613; one end of each contact branch 712 away from the fixed portion 73 forms a swinging portion 711. In this embodiment, the auxiliary moving contact 7111 is suitable for closing or disconnecting with the auxiliary static contact 613 along the X-axis direction. The auxiliary spring member 71 is further provided with a pushing portion 713, one end of which is fixedly connected to the swinging portion 711, and the other end of which is suitable for being inserted into the pushing groove 821 so as to be directly pushed by the auxiliary pushing portion 82. In this embodiment, the pushing portion 713 is at least partially inclined relative to the X-axis direction and the Z-axis direction. In this embodiment, the pushing portion 713 includes pushing branches equal in number to each contact branch 712, and the pushing branches are integrally formed with one end of the contact branch 712 away from the fixed portion 73. The lead-out member 72 is provided with a fixed portion 73, a movable lead-out portion 74 and a movable lead-out terminal 04. The fixed portion 73 is fixedly connected to the accommodating member 10 and is fixedly connected to the fixed end of the auxiliary dynamic spring member 71, mainly to the bottom end of the contact branch 712. In this embodiment, the movable lead-out portion 74 is a flat sheet perpendicular to the Y-axis direction. The movable lead-out portion 74 connects the fixed portion 73 and the movable lead-out terminal 04 and is limited in the second limiting groove 1162 along the Y-axis direction. The movable lead-out portion 74 is located on the side of the fixed portion 73 facing the auxiliary static contact member 60, see Figure 6 and Figure 6 , Figure 6 FIG. 1 shows a schematic diagram of the cooperation between the movable lead-out portion 74 and the reinforcing portion 116. Figure 8 , a cross-sectional view of the movable lead portion 74 is shown. In this embodiment, the movable lead portion 74 is also suitable for being supported on the first support surface 1163. The static lead terminal 03 and the dynamic lead terminal 04 form two lead terminals of the auxiliary monitoring switch 300. Therefore, the static lead terminal 03 and the dynamic lead terminal 04 both extend along the Y-axis direction and are flush in the Z-axis direction. In this embodiment, the static lead terminal 03 and the dynamic lead terminal 04 respectively penetrate the two second through grooves 1122 of the first side wall 112, and the static lead terminal 03 is also suitable for being supported on the second support surface 1164.

[0112] The assembly process of the relay of this embodiment is as follows:

[0113] The static contact 50 is inserted into the matching groove 1142 and one end thereof passes through one of the first through grooves 1121 of the first side wall 112 to form a connecting terminal 02;

[0114] The fixing portion 73 of the auxiliary movable contact 70 is inserted into the first limiting groove 1161, and the movable lead portion 74 of the auxiliary movable contact 70 is inserted into the second limiting groove 1162, and the movable lead portion 74 is supported on the first supporting surface 1163, so that the first limiting groove 1161 can limit the displacement of the fixing portion 73 along the X-axis direction, and the second limiting groove 1162 limits the displacement of the movable lead portion 74 along the Y-axis direction, and the movable lead terminal 04 of the auxiliary movable contact 70 passes through one of the second through grooves 1122 of the first side wall 112;

[0115] The armature assembly 30 is placed in the base 11, the insertion shaft 341 of the armature assembly 30 is inserted into the first insertion hole 1111, the driving portion 81 of the armature assembly 30 passes through the through hole 1131 of the partition wall 113 and extends into the first groove 114, and the pushing portion 713 of the auxiliary movable contact 70 is inserted into the pushing groove 821 of the auxiliary pushing portion 82;

[0116] The fixed end of the movable contact 40 is inserted into the first positioning groove 1141, and the movable spring lead-out piece 42 of the movable contact 40 penetrates the first through groove 1121 of the first side wall 112 to form a connecting terminal 02, and the swing end of the movable contact 40 is inserted into the driving groove 811 of the driving part 81, and the driving part 81 also passes through the avoidance groove 421 of the movable spring lead-out piece 42;

[0117] The auxiliary static contact 60 is fixed to the yoke 23 near the first side wall 112, that is, the second magnetic drive section 235, and the coil assembly 20 is placed in the second slot 115 so that the signal terminal 01 of the coil assembly 20 passes through the second through slot 1122, the coil winding 22 is in contact with the limit bar 1152, and the two yokes 23 are respectively inserted into the two second positioning slots 1151, and the static lead terminal 03 of the auxiliary static contact 60 passes through the other second through slot 1122 of the first side wall 112; the relay at this time can refer to Figure 4 , Figure 7 and Fig. 9 ;

[0118] Then, the base 11 is inserted into the housing 12 along the Y-axis direction and fixedly connected to the housing 12. It should be understood that the order of the various parts during the installation process can be adjusted as needed.

[0119] After installation, the contact portion 200 and the coil winding 22 are located on both sides of the first plane in the X-axis direction. The first plane is perpendicular to the X-axis direction and passes through the rotation axis. The permanent magnet is located between the two yokes 23 along the Y-axis direction. Fig. 9 The upper ends of the signal terminal 01, the static lead terminal 03 and the dynamic lead terminal 04 are all located at the same height along the Z-axis direction, and are all located on the side of the first side wall 112 close to the opening.

[0120] The working process of this embodiment is as follows:

[0121] 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 4 , one of the first attracting parts 321 attracts the first magnetic driving section 234, one of the second attracting parts 331 attracts the second magnetic driving section 235, and the driving part 81 drives the moving contact 411 and the static contact 51 to close; the auxiliary pushing part 82 drives the auxiliary moving contact 7111 and the auxiliary static contact 613 to disconnect;

[0122] When the signal terminal 01 receives the pulse signal, the armature assembly 30 rotates from the first position to the second position, see Figure 7 , another second attraction part 331 attracts the first magnetic drive segment 234, another first attraction part 321 attracts the second magnetic drive segment 235, the driving part 81 drives the moving contact 411 and the static contact 51 to disconnect; the auxiliary pushing part 82 drives the auxiliary moving contact 7111 and the auxiliary static contact 613 to close.

[0123] In this embodiment, the contact portion 200 is suitable for being driven by the armature assembly 30 and being switched on and off along the X-axis direction. It can be seen that the contact portion 200 extends along the Y-axis direction, and the coil winding 22 and the contact portion 200 are arranged on both sides of the armature assembly 30 along the X-axis direction, and the arrangement is compact, which is conducive to reducing the volume of the relay; the coil winding 22 and the contact portion 200 extend along the Y-axis direction. On this basis, each signal terminal 01 and each connecting terminal 02 also extend from the first side wall 112 along the Y-axis direction. The extension path is short, which can avoid the complexity of the internal circuit of the relay and the weak circuit strength; because the first through-groove 1121, the second through-groove 1122 and the third through-groove 1123 are all opened on the end surface of the open end of the base 11, each connecting terminal 02 extends from the first through-groove 1121 along the Y-axis direction, and each signal terminal 01 is The third through slot 1123 extends along the Y-axis direction, and each lead terminal extends from the second through slot 1122 along the Y-axis direction. Therefore, the contact portion 200, the auxiliary monitoring switch 300 and the coil assembly 20 can be placed in the base 11 from the open end of the base 11 during installation, which improves the convenience of installation. As a result, the second through slot 1122 and the third through slot 1123 on the first side wall 112 do not need to be opened very long along the Z-axis direction, which reduces the weakening of the strength of the first side wall 112, so that the auxiliary monitoring switch 300 is added to the relay, and the strength of the first side wall 112 is minimized, thereby ensuring the strength of the first side wall 112. In addition, it is also unnecessary to open through slots on other walls of the base 11, thereby improving the overall strength of the base 11 and reducing the difficulty of forming the accommodating member 10. More preferably, it is also conducive to conveniently connecting the relay to the PCB board along the Y-axis direction. The auxiliary monitoring switch 300 is arranged between the armature assembly 30 and the first side wall 112 along the Y-axis direction and close to the yoke 23 along the X-axis direction, making full use of the gap between the armature assembly 30 and the first side wall 112 and the space around the yoke 23, and installing the auxiliary monitoring switch 300 without increasing the volume of the container 10, thereby reducing the volume of the container 10. Among them, the first side wall 112 is sequentially arranged with a first through groove 1121, a second through groove 1122 and a third through groove 1123 along the X-axis direction, so that the lead terminal is located between the connection terminal 02 and the signal terminal 01 along the X-axis direction, which is conducive to realizing the electrical isolation between the weak current terminal of the relay (including the signal terminal 01 and the lead terminal) and the strong current terminal of the relay (here mainly refers to the connection terminal 02 of the contact part 200). Therefore, compared with the prior art one and the prior art two, the present embodiment has low difficulty in molding the accommodating part 10, simple molding of the accommodating part 10, small size of the relay, and compared with the prior art one, there is not much gap between the rotating shaft of the armature assembly 30 and the bottom wall 111, the rotating shaft of the armature assembly 30 does not need to be set longer, is not easy to deform, and the structure of the armature assembly 30 is stable.In addition, the auxiliary monitoring switch 300 in this embodiment occupies less space than the auxiliary monitoring switch 300 standard part, and the position of the terminal of the auxiliary monitoring switch 300 can be adjusted as needed, and the structural design is simpler. In this embodiment, the connection terminal 02, the signal terminal 01 and the lead terminal are all extended along the Y-axis direction. On the one hand, each terminal does not need to be bent in a complicated manner, which reduces the difficulty of molding and material cost, and increases its service life. On the other hand, it makes the wiring path on the PCB board simpler.

[0124] In this embodiment, the number of the first through-grooves 1121 and the connecting terminals 02 is equal and corresponds one to one, the number of the second through-grooves 1122 and the lead-out terminals is opposite and corresponds one to one, and the number of the third through-grooves 1123 and the signal terminals 01 are equal and correspond one to one. Compared with the scheme of "each connecting terminal 02 penetrates the same first through-grooves 1121, each lead-out terminal penetrates the same second through-grooves 1122, and each signal terminal 01 penetrates the same third through-grooves 1123", the first through-grooves 1121, the second through-grooves 1122 and the third through-grooves 1123 are smaller, which reduces the influence on the strength of the first side wall 112, and can better position the corresponding terminals.

[0125] In this embodiment, each lead terminal is arranged along the X-axis direction and is close to the open end of the base 11; each signal terminal 01 is arranged along the X-axis direction and is close to the open end of the base 11. Compared with the solution in which the lead terminal and the open end of the base 11 and the signal terminal 01 and the open end of the base 11 have a larger distance, the length of the second through groove 1122 and the third through groove 1123 in the Z-axis direction can be reduced, thereby further weakening the influence on the strength of the first side wall 112, and it is beneficial to limit the lead terminal and the signal terminal 01 in the Z-axis direction through the housing 12 and the corresponding groove bottom of the through groove.

[0126] In this embodiment, a reinforcing portion 116 is further provided in the base 11 , and the reinforcing portion 116 is integrally connected to the first side wall 112 and the bottom wall 111 , which not only strengthens the strength of the first side wall 112 , but also strengthens the strength of the bottom wall 111 , thereby improving the overall strength of the base 11 .

[0127] In the present embodiment, since the yoke 23 is usually fixedly connected to the end surface of the coil winding 22 and is fixedly inserted into the accommodating part 10 together with the coil winding 22, in the present embodiment, since the auxiliary monitoring switch 300 is arranged close to the yoke 23 along the X-axis direction, the auxiliary static contact 60 is directly fixedly connected to the yoke 23, and the auxiliary static contact 60 can be installed and positioned simultaneously when the yoke 23 is installed, thereby avoiding the problem of needing to install the auxiliary static contact 60 again, and the assembly is simple, thereby solving the problem of difficult assembly and positioning of small parts. In addition, the problem of easy scraping when the auxiliary static contact 60 is installed with the base 11 can also be avoided. More preferably, the stability of the yoke 23 and the coil body on the base 11 is also utilized, so that the auxiliary static contact 60 is directly supported by the yoke 23 to obtain strength and stability, so that there is no need to form a mounting portion on the accommodating part 10, so that the structure of the accommodating part 10 is simple, easy to form and saves materials. In addition, it is also beneficial to reduce the volume of the accommodating part 10 and the miniaturized design of the relay to better meet the use requirements and reduce costs. In the present embodiment, since the auxiliary moving contact 70 only needs to be installed on the base 11, it is sufficient to ensure that the auxiliary moving contact 70 can avoid other structures of the armature assembly 30 and the coil assembly 20. The auxiliary monitoring switch 300 as a whole requires less space in the container 10, thereby providing favorable conditions for installing the auxiliary monitoring switch 300 in a compact space without increasing the volume of the container 10.

[0128] In this embodiment, the reinforcing portion 116 is provided with a first supporting surface 1163 and a second supporting surface 1164 perpendicular to the Z-axis direction along the X-axis direction. The first supporting surface 1163 and the second supporting surface 1164 are respectively suitable for supporting the auxiliary moving contact 70 and the auxiliary static contact 60, thereby improving the stability of the auxiliary monitoring switch 300.

[0129] In this embodiment, the first side of the auxiliary static contact portion 61 is used to contact the auxiliary moving contact 70, and the second side thereof which is opposite to each other is abutted against the yoke 23. When the auxiliary moving contact 70 contacts the auxiliary static contact portion 61, the auxiliary static contact portion 61 is supported by the yoke 23, which further makes the auxiliary static contact 60 have good stability in the contact direction of the auxiliary moving contact 70, so that the contact between the auxiliary moving contact 70 and the auxiliary static contact 60 is reliable.

[0130] In this embodiment, the auxiliary static contact portion 61 is abutted against and fixed to the side of the yoke 23 away from the coil winding 22 along the X-axis direction. Compared with being fixed to the side of the yoke 23 facing the coil winding 22, the auxiliary static contact 60 can more easily avoid the coil winding 22, and the distance between the coil winding 22 and the armature assembly 30 (along the X-axis direction) does not need to be too large, thereby reducing the space occupied by the relay in the X-axis direction.

[0131] In this embodiment, the yoke 23 is provided with a magnetic drive section 231 extending perpendicularly to the X-axis direction, and the auxiliary static contact portion 61 is fixedly connected to the side of the magnetic drive section 231 away from the coil winding 22. The advantage of the magnetic drive section 231 having a large surface area is utilized to help improve the connection strength and stability of the auxiliary static contact 60 after being fixed to the magnetic drive section 231. Moreover, compared with the form in which the auxiliary static contact 60 is fixed to the connection section 232 of the yoke 23, the auxiliary monitoring switch 300 occupies less space in the Y-axis direction. The auxiliary moving contact 7111 is suitable for closing or disconnecting with the auxiliary static contact 613 along the X-axis direction, so that when the auxiliary moving contact 7111 is closed with the auxiliary static contact 613, the auxiliary static contact 613 can be supported by the magnetic drive section 231, and the structure is more stable.

[0132] In this embodiment, the auxiliary static contact portion 61 is in the shape of a flat sheet parallel to the magnetic drive section 231 , which helps to reduce the space occupied by the auxiliary static contact portion 61 in the X-axis direction, so as to avoid interference with the movement of the armature assembly 30 .

[0133] In this embodiment, the connection between the magnetic drive section 231 and the connecting section 232 has an arc transition surface 233, and the position where the auxiliary static contact part 61 and the magnetic drive section 231 are fixedly connected avoids the arc transition surface 233, so that the auxiliary static contact part 60 and the yoke iron 23 have a larger connection area, thereby improving the fixing strength of the auxiliary static contact part 60 and the yoke iron 23.

[0134] In this embodiment, the width direction of the yoke 23 extends along the Z-axis direction; the position where the auxiliary static contact portion 61 is fixed to the magnetic drive section 231 is close to the first end of the yoke 23 away from the bottom wall 111. Compared with the setting close to the middle part of the yoke 23, the auxiliary static contact 60 is easier to avoid the armature assembly 30 in the Z-axis direction, and it is also easier to realize the fixing operation of the auxiliary static contact 60 and the yoke 23.

[0135] In this embodiment, at the first end of the yoke 23, the magnetic drive section 231 is provided with a protrusion 2311 protruding along the Z-axis direction relative to the connecting section 232, and the auxiliary static contact portion 61 is at least partially fixed to the protrusion 2311. On the one hand, it makes it easier for the auxiliary static contact 60 to avoid the armature assembly 30 in the Z-axis direction. On the other hand, it makes it easier for the fixed position to avoid the arc transition surface 233 of the yoke 23, so that the connection between the auxiliary static contact 60 and the yoke 23 is more stable. In addition, the auxiliary static contact 60 and the yoke 23 can have a larger connection area, thereby improving the fixing strength.

[0136] In this embodiment, an avoidance gap 614 suitable for avoiding the armature assembly 30 is formed between the first connection part 611 and the second connection part 612; the second connection part 612 is farther away from the first end of the yoke 23 than the first connection part 611; along the Y-axis direction, the second connection part 612 is closer to the arc transition surface 233 of the yoke 23 than the first connection part 611; the first connection part 611 is fixedly connected to the yoke 23; the auxiliary static contact 613 is arranged on the second connection part 612, on the one hand, it makes it easier for the auxiliary static contact 60 to avoid the armature assembly 30 in the Y-axis direction and the Z-axis direction, and on the other hand, it makes the first connection part 611 can be farther away from the arc transition surface 233 of the yoke 23, thereby improving the connection stability between the first connection part 611 and the yoke 23; in addition, setting the second connection part 612 closer to the arc transition surface 233 is conducive to avoiding the second connection part 612 from interfering with the movement of the armature assembly 30.

[0137] In this embodiment, the auxiliary static contact 60 is also provided with a static lead-out terminal 03 and a bending portion 62. The bending portion 62 extends along the X-axis direction, and is connected between the first connecting portion 611 and the static lead-out terminal 03 and is located on one side of the connecting section 232 along the Z-axis direction. On the one hand, the space on one side of the connecting section 232 along the Z-axis direction is fully utilized to avoid the auxiliary static contact 60 from expanding the occupied space of the relay in the Z-axis direction; on the other hand, the static lead-out terminal 03 is close to the coil assembly 20, which is more conducive to achieving electrical isolation between the weak-current terminals of the relay (including the terminals of the coil assembly 20 and the terminals of the auxiliary monitoring switch 300) and the strong-current terminals of the relay (here mainly referring to the connecting terminal 02 of the contact part 200). In addition, the static lead-out terminal 03 is connected to the bending portion 62, which is conducive to saving the length of the bending portion 62, saving consumables and costs.

[0138] In this embodiment, the auxiliary static contact portion 61 is riveted to the yoke 23 , which makes the process simpler and the structure more stable.

[0139] In this embodiment, the riveting hole 6111 is a countersunk hole, and the riveting portion 2351 does not protrude from the riveting hole 6111 , which is more conducive to reducing the space occupied by the auxiliary static contact portion 61 in the X-axis direction.

[0140] In this embodiment, the reinforcing portion 116 is provided with a first limiting groove 1161, and the auxiliary moving contact 70 is provided with a fixed portion 73 and a swinging portion 711. The fixed portion 73 is fixedly inserted into the first limiting groove 1161 along the Z-axis direction, so that the reinforcing portion 116 can not only strengthen the overall strength of the base 11, but also limit the fixed portion 73 of the auxiliary moving contact 70, thereby eliminating the need to set a separate positioning structure for the auxiliary moving contact, thereby reducing the difficulty of molding the base 11.

[0141] In this embodiment, the reinforcing portion 116 also cooperates with the first side wall 112 to form a second limiting groove 1162 extending along the X-axis direction, and the auxiliary movable contact 70 is also provided with a movable lead portion 74, which connects the fixing portion 73 and the movable lead terminal 04 and is limited in the second limiting groove 1162 along the Y-axis direction, which is conducive to the extension of the movable lead terminal 04 along the Y-axis direction, and thereby makes the auxiliary movable contact 70 and the base 11 have more matching structures, which is more conducive to improving the stability of the movable lead terminal 04. The movable lead portion 74 is located on the side of the fixing portion 73 facing the auxiliary static contact 60, so that the movable lead terminal 04 can be close to the static lead terminal 03, which is conducive to improving the electrical isolation effect between it and the connection terminal 02.

[0142] In this embodiment, the movable lead-out portion 74 is in the shape of a flat sheet perpendicular to the Y-axis direction, which is beneficial to reducing the space occupied by the movable lead-out portion 74 in the Y-axis direction, thereby providing favorable conditions for installing the auxiliary monitoring switch 300 in a compact space.

[0143] In this embodiment, the auxiliary moving contact 70 is provided with an auxiliary moving spring 71 extending along the Z-axis direction. Compared with the auxiliary moving spring 71 extending along the Y-axis direction, the auxiliary monitoring switch 300 occupies less space in the Y-axis direction. Moreover, since the fixing portion 73 is fixedly inserted into the first limiting groove 1161, the length between the swing portion 711 and the fixed end of the auxiliary moving spring 71 is longer, which is more conducive to reducing the stress concentration phenomenon of the auxiliary moving spring 71 and improving the service life. The auxiliary moving spring 71 is a sheet-like structure with the thickness direction extending along the X-axis direction, which is conducive to reducing the space occupied by the auxiliary moving spring 71 in the X-axis direction, and further conducive to installing the auxiliary moving contact 70 in a compact space.

[0144] In this embodiment, one end of the pushing portion 713 is fixedly connected to the swinging portion 711 of the auxiliary dynamic spring member 71, and the other end is suitable for being driven by the armature assembly 30. The pushing portion 713 is arranged close to the swinging portion 711, which is conducive to ensuring stable contact between the auxiliary dynamic contact 7111 and the auxiliary static contact 613.

[0145] In this embodiment, the auxiliary static contact 60 is provided with at least two auxiliary static contacts 613, and each auxiliary static contact 613 is located at the same height along the Z-axis direction; the auxiliary dynamic spring member 71 is provided with contact branches 712 equal to and corresponding to the auxiliary static contacts 613, one end of each contact branch 712 is fixed to the fixed portion 73, and the other end is provided with an auxiliary dynamic contact 7111 suitable for abutting the auxiliary static contact 613; one end of each contact branch 712 away from the fixed portion 73 forms a swing portion 711. On the one hand, the provision of multiple auxiliary dynamic and static contacts 51 can improve the connection reliability of the auxiliary monitoring switch 300, and is also beneficial to the processing of the auxiliary dynamic contact 70 and the auxiliary static contact 60. On the other hand, it is also beneficial to the deformation of the auxiliary dynamic contact 70 along the X-axis direction, thereby improving the connection reliability and prolonging the service life; each auxiliary static contact 613 is located at the same height along the Z-axis direction so that the contact pressure of each auxiliary dynamic contact 7111 is consistent with that of each auxiliary static contact 613.

[0146] In this embodiment, under normal circumstances, if the armature assembly 30 drives the movable contact 40 to move by driving an independent pushing card, then the area of ​​the yoke 23 on the side facing the contact portion 200 along the X-axis direction is usually used as the activity space of the pushing card. If it is necessary to install the auxiliary monitoring switch 300 on the side of the armature 31 along the Y-axis direction, it is necessary to lead out a swing arm from the armature assembly 30 to push the auxiliary monitoring switch 300, and the swing arm also needs to bypass the armature 31 in the armature assembly 30, resulting in a more complex structure, large consumables and large volume. In this embodiment, the driving member 80 is provided with an integrally formed driving portion 81 and an auxiliary pushing portion 82. The driving member 80 is integrally formed with the insulating member 34, and the insulating member 34 is fixedly connected to the permanent magnet member. Through reasonable design and processing, the driving portion 81 can avoid the space for installing the auxiliary monitoring switch 300, and the small-structured auxiliary pushing portion 82 is also used to drive the auxiliary movable contact 70 in the auxiliary monitoring switch 300 to move. The structure is simple, the consumables are small, the molding is good, and there is no need to increase the volume of the relay. In this embodiment, a driving part 81 and an auxiliary pushing part 82 are integrally arranged on the driving member 80, which has a simple structure, is easy to form and is conducive to reducing production costs. In addition, the driving part 81 and the auxiliary pushing part 82 are relatively stable relative to the armature assembly 30, thereby reducing the shaking of the moving contact 40 and the auxiliary moving contact 70 during disconnection, avoiding affecting the arc burning characteristics of the disconnecting arc, and reducing the hazards of contact erosion and uncontrolled arc erosion of other components.

[0147] Example 2

[0148] The structure of the second embodiment is basically the same as that of the first embodiment, except that the structure of the auxiliary static contact 60 is different. Fig.15In this embodiment, the auxiliary static contact part 61 does not include the first connection part 611 and the second connection part 612. The auxiliary static contact 613 is located between the position where the auxiliary static contact part 61 is fixed to the magnetic drive section 231 and the arc transition surface 233 along the Y-axis direction. When the auxiliary moving contact 7111 contacts the auxiliary static contact 613, the auxiliary static contact 60 has an electrical path, and the position where the auxiliary static contact 60 is fixed to the magnetic drive section 231 is located outside the electrical path. The auxiliary static contact 60 is also provided with a static lead-out terminal 03 and a bending part 62. The bending part 62 extends along the X-axis direction, is connected between the auxiliary static contact part 61 and the static lead-out terminal 03, and is located on one side of the connection section 232 along the Z-axis direction.

[0149] In this embodiment, the auxiliary static contact 613 is located between the position where the auxiliary static contact part 61 and the magnetic drive section 231 are fixed and the arc transition surface 233 along the Y-axis direction, which is conducive to realizing that the position where the auxiliary static contact 60 and the magnetic drive section 231 are fixed is located outside the electrical path, and makes the fixed position farther away from the arc transition surface 233 of the yoke 23, and the connection between the auxiliary static contact 60 and the yoke 23 is more stable.

[0150] In this embodiment, when the auxiliary moving contact 7111 contacts the auxiliary static contact 613, the auxiliary static contact 60 has an electrical path, and the position where the auxiliary static contact 60 is fixed to the magnetic drive section 231 is located outside the electrical path. When the auxiliary monitoring switch 300 is closed, the current does not enter the yoke 23 through the position where the auxiliary static contact 60 is fixed to the magnetic drive section 231. Therefore, there is no need to set an insulating structure between the auxiliary static contact 60 and the magnetic drive section 231, so that the current of the auxiliary monitoring switch 300 can be avoided from affecting the magnetic circuit in the yoke 23, thereby reducing the complexity of the structure.

[0151] In this embodiment, the auxiliary static contact 60 is also provided with a static lead-out terminal 03 and a bending portion 62. The bending portion 62 extends along the X-axis direction, is connected between the auxiliary static contact portion 61 and the static lead-out terminal 03 and is located on one side of the connecting section 232 along the Z-axis direction. On the one hand, the space on one side of the connecting section 232 along the Z-axis direction is fully utilized to avoid the auxiliary static contact 60 from expanding the occupied space of the relay in the Z-axis direction; on the other hand, the static lead-out terminal 03 is made close to the coil assembly 20, which is more conducive to achieving electrical isolation between the weak-current terminals of the relay (including the terminals of the coil assembly 20 and the terminals of the auxiliary monitoring switch 300) and the strong-current terminals of the relay (here mainly referring to the connecting terminal 02 of the contact part 200). In addition, the static lead-out terminal 03 is connected to the bending portion 62, which is conducive to saving the length of the bending portion 62, saving consumables and costs.

[0152] Example 3

[0153] The structure of the embodiment 3 is basically the same as that of the embodiment 1, except that the structure of the auxiliary static contact 60 is different. Fig.16 In this embodiment, the auxiliary static contact portion 61 does not include the first connection portion 611 and the second connection portion 612. The side of the magnetic drive section 231 of the yoke 23 away from the coil winding 22 is stamped to form a mounting groove 2352 with an opening away from the coil winding 22 and a riveted portion 2351 protruding from the mounting groove 2352; the auxiliary static contact 60 is installed in the mounting groove 2352 and is provided with a riveted hole 6111 that cooperates with the riveted portion 2351. There are three riveted portions 2351, which are arranged close to the auxiliary static contact portion 61 and away from the arc transition surface 233. When the auxiliary moving contact 7111 contacts the auxiliary static contact 613, the auxiliary static contact 60 has an electrical path, and the position where the auxiliary static contact 60 is fixed to the magnetic drive section 231 is located outside the electrical path.

[0154] In this embodiment, the magnetic drive section 231 of the yoke 23 is stamped on the side away from the coil winding 22 to form a mounting groove 2352 with an opening away from the coil winding 22 and a riveted portion 2351 protruding from the mounting groove 2352. The auxiliary static contact 60 is installed in the mounting groove 2352 and is provided with a rivet hole 6111 that cooperates with the riveted portion 2351. The stamping process allows the riveted portion 2351 to have a longer length in the X-axis direction, thereby also allowing the auxiliary static contact 60 to have a larger thickness, and when applied to a relay, it occupies less space in the X-axis direction.

[0155] In this embodiment, when the auxiliary moving contact 7111 contacts the auxiliary static contact 613, the auxiliary static contact 60 has an electrical path, and the position where the auxiliary static contact 60 is fixed to the magnetic drive section 231 is located outside the electrical path. When the auxiliary monitoring switch 300 is closed, the current does not enter the yoke 23 through the position where the auxiliary static contact 60 is fixed to the magnetic drive section 231. Therefore, there is no need to set an insulating structure between the auxiliary static contact 60 and the magnetic drive section 231, so that the current of the auxiliary monitoring switch 300 can be avoided from affecting the magnetic circuit in the yoke 23, thereby reducing the complexity of the structure.

[0156] In this embodiment, the auxiliary static contact 60 is also provided with a static lead-out terminal 03 and a bending portion 62. The bending portion 62 extends along the X-axis direction, is connected between the auxiliary static contact portion 61 and the static lead-out terminal 03 and is located on one side of the connecting section 232 along the Z-axis direction. On the one hand, the space on one side of the connecting section 232 along the Z-axis direction is fully utilized to avoid the auxiliary static contact 60 from expanding the occupied space of the relay in the Z-axis direction; on the other hand, the static lead-out terminal 03 is made close to the coil assembly 20, which is more conducive to achieving electrical isolation between the weak-current terminals of the relay (including the terminals of the coil assembly 20 and the terminals of the auxiliary monitoring switch 300) and the strong-current terminals of the relay (here mainly referring to the connecting terminal 02 of the contact part 200). In addition, the static lead-out terminal 03 is connected to the bending portion 62, which is conducive to saving the length of the bending portion 62, saving consumables and costs.
