[0054] According to some embodiments of the present application, the second lead-out piece of the lead-out member is connected to the load via a second fastener, and the second fastener is a screw.

[0055] One embodiment of the above application has at least the following advantages or beneficial effects:

[0056] The lead-out piece of the embodiment of the present application forms a first notch between the first lead-out piece and the second lead-out piece, and the first projection of the geometric center of the first connecting portion on the first target plane falls within the second projection of the first notch on the first target plane, thereby reducing the force acting on the first lead-out piece, avoiding to a certain extent the influence of the prying of the first lead-out piece on the firmness of the connection between the first lead-out piece and the static contact, and further avoiding the rupture of the insulating cover.

[0057] Furthermore, the second lead piece is vertically connected to the first lead piece. By bending the second lead piece, the installation direction of the second connection portion and the load can be roughly the same as the installation direction of the third mounting hole of the mounting foot and the plugging and unplugging direction of the external connector, which is convenient for the overall installation of the relay.

[0058] Furthermore, along the first direction, the distance between the two second connection parts of the two lead-out members is greater than the distance between the two first connection parts.

[0059] Furthermore, the axis of the second mounting hole is parallel to the plugging direction of the external connector and the slot, and is perpendicular to the movement direction of the moving assembly, so that the relay can be installed horizontally. At the same time, the axis of the second mounting hole is consistent with the plugging direction of the external connector and the slot, and is perpendicular to the mounting surface of the external device, so that the installation direction of the lead-out piece and the load and the plugging direction of the external connector and the connector assembly are all concentrated in one direction, which is convenient for plugging and unplugging the external connector and the connector assembly, and for connecting the lead-out piece to the load through its second mounting hole, which is convenient for the installation of the relay and is conducive to the realization of automated assembly.

[0060] Furthermore, a target angle is formed between the axis of the second mounting hole of the mounting foot and the movement direction of the moving component, so that the installation direction of the mounting foot, the installation direction of the lead-out piece and the load, and the external connector and the connector component are all concentrated in one direction and can be installed in the same direction.

[0061] Furthermore, the connector, the conductive member and the socket are integrally formed to form an integral part. When installing, it is only necessary to electrically connect the multiple conductive members of the integral part with the lead pins and the auxiliary static contact assembly, which is simple to assemble and saves installation space. In addition, when the structure of the relay body remains unchanged, the position of the connector and the bending direction of the conductive member can be adjusted to match the different arrangement positions of the lead pins and the auxiliary static contact assembly, and the lead-out direction of the lead-out member and the plug-in direction of the external connector can be flexibly adjusted.

[0082] like Figure 1 and Figure 2 As shown, the relay of the embodiment of the present application includes a housing 10, a relay body 20, a connector assembly 60 and a lead-out member 70. The relay body 20 and the connector assembly 60 are accommodated in the housing 10. The relay body 20 is connected to the load through the lead-out member 70.

[0083] The housing 10 includes an outer cover 11 and a base 12 , and the outer cover 11 and the base 12 are connected to form a chamber for accommodating the relay body 20 and the connector assembly 60 .

[0084] It is understandable that the present application does not specifically limit the shapes of the outer cover 11 and the base 12, and the outer cover 11 and the base 12 can form a chamber that accommodates the relay body 20 and the connector assembly 60 after being connected. For example, in one embodiment, the outer cover 11 is a rectangular parallelepiped with an opening, and the base 12 is a plate-shaped base 12, which is buckled into the opening of the outer cover 11. The outer cover 11 and the base 12 can be connected by a snap-fit ​​method, but it is not limited thereto.

[0085] The outer wall surface of the side wall of the outer cover 11 is also protruded with a mounting foot 113 . When the relay is mounted on the external device 1 , the relay is connected to the external device 1 through the mounting foot 113 .

[0086] In one embodiment, the mounting foot 113 has a third mounting hole 1131, through which the mounting foot 113 is mounted on the external device 1. For example, the locking member passes through the third mounting hole 1131 to fasten the mounting foot 113 to the external device 1.

[0087] like Figure 2 As shown, the relay body 20 includes an insulating cover 21 , a yoke iron plate 25 , a pair of stationary contacts 22 , an arc extinguishing assembly 26 , a moving assembly 30 and a magnetic circuit portion 40 .

[0088] The insulating cover 21 has an inner cavity 212, a pair of static contacts 22 are installed on the top of the insulating cover 21, at least part of each static contact 22 extends into the inner cavity 212 of the insulating cover 21, and a static contact point is also provided at the bottom of each static contact 22, and the static contact point can be integrally or separately provided at the bottom of the static contact 22. One static contact 22 serves as a terminal for current to flow in, and the other static contact 22 serves as a terminal for current to flow out.

[0089] In the embodiment of the present application, two first openings 211 are provided on the top of the insulating cover 21, and each first opening 211 is connected to the inner cavity 212. A pair of static contacts 22 are respectively provided in the two first openings 211. Moreover, each static contact 22 and the insulating cover 21 can be connected by welding, but the present invention is not limited thereto.

[0090] The top of the outer cover 11 is provided with a second opening 114 aligned with the first opening 211 . The static contact 22 is inserted into the second opening 114 , and one end of the static contact 22 extends out of the outer surface of the outer cover 11 .

[0091] It can be understood that the insulating cover 21 can be made of ceramic material, that is, the insulating cover 21 is a ceramic cover, but it is not limited thereto. For example, in other embodiments, the insulating cover 21 can also be made of plastic material.

[0092] In an embodiment of the present application, the insulating cover 21 is made of ceramic material, and the insulating cover 21 is connected to the yoke iron plate 25 through a frame piece 24. The frame piece 24 can be a metal piece with an annular structure, such as an iron-nickel alloy. One end of the frame piece 24 is connected to the opening edge of the insulating cover 21, for example, by laser welding, brazing, resistance welding, gluing, etc. The other end of the frame piece 24 is connected to the yoke iron plate 25, which can also be done by laser welding, brazing, resistance welding, gluing, etc. A frame piece 24 is arranged between the insulating cover 21 and the yoke iron plate 25 to facilitate the connection between the insulating cover 21 and the yoke iron plate 25.

[0093] Please continue reading Figure 2 The moving assembly 30 includes a moving contact piece 31 , a first elastic member 32 and a push rod member 33 .

[0094] For the convenience of explanation, the arrangement direction of the pair of stationary contacts 22 is defined as the first direction D1, and the movement direction of the moving assembly 30 is defined as the second direction D2, wherein the first direction D1 is perpendicular to the second direction D2. The direction perpendicular to both the first direction D1 and the second direction D2 is defined as the third direction D3.

[0095] The movable contact piece 31 is disposed in the insulating cover 21 , and two ends of the movable contact piece 31 along the first direction D1 are respectively used to contact the bottom of a pair of stationary contacts 22 .

[0096] The push rod member 33 is movably disposed in the first through hole 251 of the yoke plate 25 , and part of the push rod member 33 extends out of the side surface of the yoke plate 25 facing the stationary contact 22 , and part of the push rod member 33 extends out of the side surface of the yoke plate 25 facing away from the stationary contact 22 .

[0097] The movable contact piece 31 is movably mounted on the portion of the push rod member 33 extending from the side surface of the yoke iron plate 25 facing the stationary contact 22. The first elastic member 32 is used to apply an elastic force to the movable contact piece 31 toward the stationary contact 22 to provide contact pressure.

[0098] As an example, the first elastic member 32 is a spring or a leaf spring, but is not limited thereto. In addition, the number of the first elastic member 32 may be one or more. When the number of the first elastic member 32 is multiple, the multiple first elastic members 32 may all be springs, or all be leaf springs, or may be a combination of leaf springs and springs, and the present application does not make any special limitation on this.

[0099] The side surface of the yoke iron plate 25 facing away from the static contact 22 is also covered with a metal cover 27, and the metal cover 27 covers the first through hole 251 of the yoke iron plate 25. The push rod member 33 extending from the side surface of the yoke iron plate 25 facing away from the static contact 22 is inserted into the metal cover 27.

[0100] Please continue reading Figure 2 The magnetic circuit part 40 includes a moving iron core 41, a stationary iron core 42, a coil frame 43 and a coil 44. The coil frame 43 is in a hollow cylindrical shape and is made of insulating material. The coil frame 43 is located on the side of the yoke iron plate 25 facing away from the stationary contact 22 and surrounds the outer periphery of the metal cover 27. The coil 44 is wound around the outer periphery of the coil frame 43.

[0101] The coil frame 43 includes a bobbin 432, a first flange 433 and a second flange 434. The coil 44 is wound around the outer periphery of the bobbin 432, the first flange 433 and the second flange 434 are respectively connected to the axial ends of the bobbin 432, and the coil 44 is disposed between the first flange 433 and the second flange 434.

[0102] The static iron core 42 is fixedly disposed in the metal cover 27, and part of the static iron core 42 is inserted into the first through hole 251. The static iron core 42 has a second through hole 421, and the second through hole 421 corresponds to the position of the first through hole 251, so that the push rod member 33 can be movably penetrated in the first through hole 251 and the second through hole 421. The moving iron core 41 is movably disposed in the metal cover 27, and is arranged relative to the static iron core 42 in the second direction D2. The moving iron core 41 is connected to the push rod member 33, and is used to be attracted by the static iron core 42 when the coil 44 is energized. The moving iron core 41 and the push rod member 33 can be connected by screwing, riveting, welding or other methods.

[0103] like Figure 2 As shown, the magnetic circuit portion 40 further includes a second elastic member 46, which is located in the metal cover 27 and disposed between the static iron core 42 and the moving iron core 41, and is used to reset the moving iron core 41 when the coil 44 is de-energized.

[0104] In one embodiment, the second elastic member 46 is a spring and is sleeved on the outer circumference of the push rod member 33 , but the present invention is not limited thereto.

[0105] It should be noted that when the coil 44 is energized, the stationary iron core 42 attracts the moving iron core 41 to move upward, and the moving iron core 41 can drive the push rod member 33 to move upward. When the moving contact piece 31 contacts the stationary contact 22, the moving contact piece 31 is stopped by the stationary contact 22, and the push rod member 33 will continue to move upward until the overtravel is completed.

[0106] During the overtravel process, the first elastic member 32 is squeezed by the push rod member 33 and can provide elastic force to the movable contact piece 31 to provide contact point pressure.

[0107] like Figure 2 As shown, the magnetic circuit part 40 also includes a U-shaped yoke 47 and a magnetic tube 45. The U-shaped yoke 47 includes a bottom yoke plate 471 and two side yoke plates 472, the two side yoke plates 472 are respectively connected to the two ends of the bottom yoke plate 471 along the first direction D1, and the two side yoke plates 472 are arranged opposite to each other along the first direction D1. The bottom yoke plate 471 is arranged on the side of the coil frame 43 facing away from the static contact 22, and the ends of the two side yoke plates 472 away from the bottom yoke plate 471 are respectively connected to the two ends of the yoke plate 25 along the first direction D1. The coil 44, the coil frame 43, the metal cover 27 and the moving iron core 41 are accommodated in the space surrounded by the bottom yoke plate 471 and the two side yoke plates 472 of the yoke plate 25 and the U-shaped yoke 47. The magnetic tube 45 is sleeved on the outer periphery of the metal cover 27, and the magnetic tube 45 is located between the metal cover 27 and the coil frame 43.

[0108] like Figure 2 As shown, the arc extinguishing part 26 includes a permanent magnet 262, and the permanent magnet 262 is arranged on the outer side of the insulating cover 21. By arranging the permanent magnet 262 on the outer periphery of the insulating cover 21, a magnetic field can be formed around the stationary contact 22 and the moving contact piece 31. Therefore, through the effect of the magnetic field, the arc generated between the stationary contact 22 and the moving contact 31 will be stretched in a direction away from each other, thereby achieving arc extinguishing.

[0109] The arc extinguishing part 26 further includes a yoke clamp 261, and a permanent magnet 262 is disposed between a side surface of the yoke clamp 261 facing the insulating cover 21 and an outer peripheral surface of the insulating cover 21. By designing that the yoke clamp 261 surrounds the permanent magnet 262, it is possible to prevent the magnetic field generated by the permanent magnet 262 from spreading outward and affecting the arc extinguishing effect.

[0110] In one embodiment, the yoke clip 261 is made of a soft magnetic material, which may include but is not limited to iron, cobalt, nickel, and alloys thereof.

[0111] It is understandable that the number of the yoke clips 261 can be one or two. When the number of the yoke clips 261 is one, the yoke clip 261 forms an annular structure surrounding the outer periphery of the insulating cover 21. When the number of the yoke clips 261 is two, each yoke clip 261 can be U-shaped and arranged opposite to each other along the first direction D1, and the two yoke clips 261 respectively surround the two ends of the insulating cover 21 along the first direction D1.

[0112] like Figure 2 As shown, the relay of the embodiment of the present application may further include an auxiliary contact assembly 80 , and the auxiliary contact assembly 80 is used to detect the closing condition of the moving contact piece 31 and the static contact 22 .

[0113] The auxiliary contact assembly 80 includes an auxiliary moving contact piece 81 and two auxiliary static contact assemblies 82. The two ends of the auxiliary moving contact piece 81 are used to contact the two auxiliary static contact assemblies 82 respectively. The auxiliary moving contact piece 81 is connected to the push rod member 33 and moves with the push rod member 33. The auxiliary static contact assembly 82 is installed on the yoke iron plate 25.

[0114] In one embodiment, the relay is a horizontal relay, wherein the horizontal relay refers to a horizontal relay in which the movement direction of the actuator 30 is parallel to the installation surface 1 a of the external device 1 .

[0115] like Figures 3 to 6 As shown, the lead-out piece 70 includes a first lead-out piece 71 and a second lead-out piece 72. The first lead-out piece 71 has a first connection portion 711 for connecting to the static contact 22 of the relay body 20. The second lead-out piece 72 is connected to the first lead-out piece 71 for connecting to the external device 1. The first lead-out piece 71 and the second lead-out piece 72 together form a first notch 73, the orthographic projection of the geometric center of the first connection portion 711 on the first target plane is the first projection, the orthographic projection of the first notch 73 on the first target plane is the second projection, and the first projection falls inside the second projection. The first target plane is perpendicular to the first lead-out piece 71. In the embodiment of the present application, the first target plane is perpendicular to the third direction D3.

[0116] It should be noted that when the relay is installed, the mounting foot 113 is connected to the external device 1, and the lead-out piece 70 is connected to the load. If the positioning between the external device 1 and the load is not good, whether the mounting foot 113 is connected to the external device 1 first, and then the lead-out piece 70 is connected to the load, or the lead-out piece 70 is connected to the load first, and then the mounting foot 113 is connected to the external device 1, a force will be generated on the lead-out piece 70, and this force will make the connection between the lead-out piece 70 and the stationary contact 22 unreliable, and even cause the stationary contact 22 to pry relative to the insulating cover 21, thereby causing the insulating cover 21 to rupture.

[0117] It should be noted that the first lead-out piece 71 and the second lead-out piece 72 jointly form a first notch 73, the orthographic projection of the geometric center of the first connecting portion 711 on the first target plane is the first projection, the orthographic projection of the first notch 73 on the first target plane is the second projection, and the first projection falls inside the second projection. It can be seen that, by setting the first notch 73, the connection position between the first lead-out piece 71 and the second lead-out piece 72 does not cover the geometric center of the first connecting portion 711 in the third direction D3.

[0118] It can be seen that the lead-out piece 70 of the embodiment of the present application forms a first notch 73 between the first lead-out piece 71 and the second lead-out piece 72, and the first projection of the geometric center of the first connecting portion 711 on the first target plane falls within the second projection of the first notch 73 on the first target plane, thereby reducing the force acting on the first lead-out piece 71, and to a certain extent avoiding the effect of the first lead-out piece 71 prying on the first lead-out piece 71 and thus affecting the firmness of the connection between the first lead-out piece 71 and the static contact 22, thereby further avoiding the rupture of the insulating cover 21.

[0119] like Figures 3 to 6 As shown, there can be multiple connection modes between the first lead-out piece 71 and the stationary contact 22, and between the second lead-out piece 72 and the load.

[0120] For example, the first connection portion 711 is a first mounting hole 711a, and the first mounting hole 711a penetrates the first lead-out piece 71 along the thickness direction of the first lead-out piece 71. The relay further includes a first fastener 90, and the first fastener 90 is penetrated through the first mounting hole 711a of the first lead-out piece 71 to fasten the first lead-out piece 71 to the stationary contact 22. The first fastener 90 may be a screw, a rivet, etc., which is not limited in the present application.

[0121] The second lead-out piece 72 has a second connection portion 721 connected to the external device 1; the second connection portion 721 can be connected to the external device 1 through a second fastener (not shown in the figure). For example, the second fastener is a screw, a rivet, or the like.

[0122] Further, the second connection portion 721 is a second mounting hole 721a, and the second mounting hole 721a penetrates the second lead-out piece 72 along the thickness direction of the second lead-out piece 72. The second mounting hole 721a can be penetrated by a second fastener to fasten the second lead-out piece 72 to the load.

[0123] It can be understood that when the second connecting portion 721 is a second mounting hole 721a, the second fastener is a screw, and the lead-out member 70 is fastened to the external device 1 by passing the second fastener through the second mounting hole 721a, the lead-out member 70 is provided with a first notch 73, which can reduce the torque on the first lead-out piece 71 and ensure the firmness of the connection between the first lead-out piece 71 and the static contact 22.

[0124] Of course, in other embodiments, the first connection portion 711 and the second connection portion 721 may also be welding portions, that is, the first lead-out piece 71 is welded to the stationary contact 22 , and the second lead-out piece 72 is welded to the load.

[0125] It is understandable that the first lead-out piece 71 and the second lead-out piece 72 can be connected in the same manner, for example, the first lead-out piece 71 and the second lead-out piece 72 are both connected by fasteners or welded.

[0126] In addition, the first lead piece 71 and the second lead piece 72 may also be connected in different ways. For example, the first lead piece 71 is connected to the stationary contact 22 via the first fastener 90, and the second lead piece 72 is connected to the load via welding.

[0127] like Figure 6 As shown, the second lead-out piece 72 is bent and connected to the first lead-out piece 71. Further, the second lead-out piece 72 is vertically connected to the first lead-out piece 71. By bending the second lead-out piece 72, the installation direction of the second connection portion 721 and the load can be made substantially the same as the installation direction of the third mounting hole 1131 of the mounting foot 113 and the plug-in and unplug direction of the external connector, which facilitates the overall installation of the relay. The plug-in and unplug direction of the external connector will be described in detail below.

[0128] like Figure 3 and Figure 4 As shown, the portion of the housing 10 corresponding to the static contact 22 has a mounting groove 13, and at least a portion of the first lead-out piece 71 is located in the mounting groove 13. On the one hand, the groove wall of the mounting groove 13 can increase the strength of the connection between the lead-out piece 70 and the mounting groove 13; on the other hand, the groove wall of the mounting groove 13 can increase the creepage distance between the positive and negative loads.

[0129] like Figure 3 As shown, the mounting groove 13 has two first groove walls 131 and a second groove wall 132 . The two first groove walls 131 are arranged opposite to each other along the third direction D3 , and two ends of the second groove wall 132 along the third direction D3 are respectively connected to the two first groove walls 131 .

[0130] like Figure 1 As shown, at least one of the two first groove walls 131 has a convex inner wall surface with a limiting portion 1311, which abuts against the lead-out member 70. The limiting portion 1311 can limit the lead-out member 70 after it is installed in the installation groove 13, so that the installation size of the lead-out member 70 meets the preset requirements.

[0131] Furthermore, the limiting portion 1311 has a guiding inclined surface 1311 a, and the guiding inclined surface 1311 a is used to guide the lead-out member 70 to be installed into the installation groove 13 along the second direction.

[0132] like Figure 4 As shown, a positioning portion 1321 is protruded from the surface of the second groove wall 132 facing the mounting groove 13. Figure 6 As shown, the side edge of the first lead-out piece 71 has a positioning groove 712. The positioning portion 1321 is located in the positioning groove 712 of the first lead-out piece 71. Through the positioning and matching of the positioning portion 1321 and the positioning groove 712, the stability of the lead-out member 70 in the mounting groove 13 can be improved, and the lead-out member 70 can be prevented from rotating relative to the housing.

[0133] There are two mounting grooves 13, and the two mounting grooves 13 are symmetrically arranged about the midline of the connecting line between the pair of stationary contacts 22, and the midline is perpendicular to the second lead-out piece 72 (i.e., the midline is parallel to the third direction D3); the stationary contact 22 is located in the middle position between the two first groove walls. There are two lead-out pieces 70, and the first lead-out pieces 71 of the two lead-out pieces 70 are respectively located in the two mounting grooves 13 and connected to the stationary contact 22; the two lead-out pieces 70 are symmetrically arranged about the midline.

[0134] like Figure 5 As shown, the two first groove walls 131 of the mounting groove 13 are respectively defined as the first sub-groove wall 131a and the second sub-groove wall 131b, the two first sub-groove walls 131a of the two mounting grooves 13 are located on the same side, and the two second sub-groove walls 131b are located on the same side; there is a first distance W1 between the positioning portion 1321 and the first sub-groove wall 131a, and there is a second distance W2 between the positioning portion 1321 and the second sub-groove wall 131b, and the first distance W1 is smaller than the second distance W2.

[0135] It is understandable that, since the first distance W1 is smaller than the second distance W2, the positioning portion 1321 can also play an anti-wrong installation function to avoid the problem of reverse installation of the two lead-out components 70.

[0136] like Figure 5 As shown, a convex 713 is provided on one side surface of the first lead-out piece 71 connected to the second lead-out piece 72 , and the convex 713 contacts the groove wall of the installation groove 13 .

[0137] like Figure 4 As shown, the two lead-out members 70 are symmetrically arranged with respect to the perpendicular midline of the line connecting the pair of stationary contacts 22, and the perpendicular midline is parallel to the third direction D3. In addition, along the first direction D1, the distance W3 between the two second connection portions 721 of the two lead-out members 70 is greater than the distance W4 between the two first connection portions 711. Since the distance between the two second connection portions 721 is large, the electrical clearance is increased, and the safety is improved.

[0138] Of course, in other embodiments, W3 may also be smaller than W4.

[0139] like Figure 7 and Figure 8 As shown, the connector assembly 60 is electrically connected to the relay body 20; the connector assembly 60 has a slot 631 for inserting an external connector (not shown in the figure).

[0140] The axis of the second mounting hole 721 a of the lead-out member 70 is parallel to the plugging direction of the external connector and the slot 631 , and is perpendicular to the moving direction (the second direction D2 ) of the moving assembly 30 .

[0141] It should be noted that when the relay is installed on the external device 1, if a vertical installation is adopted, the movement direction (second direction D2) of the moving component 30 is perpendicular to the installation surface 1a of the external device 1; if a horizontal installation is adopted, the movement direction (second direction D2) of the moving component 30 is parallel to the installation surface 1a of the external device 1.

[0142] In the relay of the embodiment of the present application, the axis of the second mounting hole 721a is parallel to the plug-in direction of the external connector and the slot 631, and is perpendicular to the movement direction of the moving assembly 30, so that the relay can be installed horizontally, and when the relay is connected to the external device, the external device does not need to reserve too much installation space, thereby achieving the effect of reducing the volume of the external device. At the same time, the axis of the second mounting hole 721a and the plug-in direction of the external connector and the slot 631 are consistent, so that the installation direction of the lead-out piece 70 and the load and the plug-in direction of the external connector and the connector assembly 60 are all concentrated in one direction, which is convenient for the plug-in and unplugging of the external connector and the connector assembly 60, and convenient for the lead-out piece 70 to be connected to the load through its second mounting hole 721a, which is convenient for the installation of the relay and is conducive to the realization of automated assembly.

[0143] In one embodiment, the lead-out member 70 may be connected to the load via a second fastener passing through the second mounting hole 721 a .

[0144] like Figure 1 and Figure 7 As shown, the axis of the third mounting hole 1131 of the mounting foot 113 and the movement direction (second direction D2) of the moving assembly 30 present a target angle α, so that the mounting direction of the mounting foot 113, the mounting direction of the lead-out member 70 and the load, and the external connector and the connector assembly 60 are all concentrated in one direction and can be installed in the same direction. Among them, α is between 30 degrees and 90 degrees, for example, α is 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, and 90 degrees.

[0145] like Figure 8 and Fig. 9 As shown, the connector assembly 60 includes a connector 61, a conductive member 62 and a socket 63. The conductive member 62 is made of a conductive material, such as metal; the connector 61 and the socket 63 are made of an insulating material, such as plastic. The connector 61, the conductive member 62 and the socket 63 are integrally formed to form an integral part. For example, the connector 61, the conductive member 62 and the socket 63 are connected by integral injection molding, but the present invention is not limited thereto.

[0146] Optionally, the connector assembly 60 further includes a reinforcing member 64, which is integrally formed with the conductive member 62. The reinforcing member 64 can improve the structural strength of the conductive member 62, thereby preventing deformation of the conductive member 62 due to its excessive length, thereby preventing adjacent conductive members 62 from contacting each other.

[0147] In one embodiment, the reinforcing member 64 is made of an insulating material, and the reinforcing member 64 and the conductive member 62 are connected by integral injection molding, but the present invention is not limited thereto.

[0148] The connecting member 61 is mechanically connected to the relay body 20 , and the conductive member 62 is electrically connected to the relay body 20 . The socket 63 has a slot 631 , and the end of the conductive member 62 is disposed in the slot 631 .

[0149] In the embodiment of the present application, the connecting member 61 is mechanically connected to the relay body 20, and the conductive member 62 is electrically connected to the relay body 20, so that the fixed connection between the connector assembly 60 and the relay body 20 is mainly completed through the connecting member 61, and the conductive member 62 and the relay body 20 mainly play the role of electrical connection. When the relay vibrates, the mechanical connection structure between the connecting member 61 and the relay body 20 can bear the vibration force and prevent the vibration force from acting on the electrical connection between the conductive member 62 and the relay body 20, resulting in poor electrical connection.

[0150] It can be understood that, in one embodiment, the conductive member 62 of the connector assembly 60 is electrically connected to the coil 44, and the coil 44 is electrically connected to the conductive member 62 through the lead pin 441; in another embodiment, when the relay includes the auxiliary contact assembly 80, the number of conductive members 62 included in the connector assembly 60 is multiple, some of the conductive members 62 are electrically connected to the coil 44 through the lead pin 441, and the remaining conductive members 62 are electrically connected to the auxiliary static contact assembly 82 of the auxiliary contact assembly 80. The electrical connection can be achieved by welding, but is not limited thereto.

[0151] In the embodiment of the present application, the number of the conductive members 62 is four, and two of the conductive members 62 are electrically connected to the two lead pins 441 of the coil 44 respectively, and the other two conductive members 62 are electrically connected to the two auxiliary static contact components 82 of the auxiliary contact component 80 respectively.

[0152] It can be understood that the connector 61, the conductive member 62 and the socket 63 are integrally formed and form an integral part. When installing, it is only necessary to electrically connect the multiple conductive members 62 of the integral part with the lead pin 441 and the auxiliary static contact assembly 82, which is simple to assemble and saves installation space. In addition, when the structure of the relay body 20 remains unchanged, the position of the connector 61 and the bending direction of the conductive member 62 can be adjusted to match the different arrangement positions of the lead pin 441 and the auxiliary static contact assembly 82, and the lead-out direction of the lead-out member 70 and the plug-in direction of the external connector can be flexibly adjusted.

[0153] like Fig.10 and Fig.11As shown, a first positioning structure is provided between the conductive member 62 and the socket 63. By providing the first positioning structure between the conductive member 62 and the socket 63, on the one hand, the conductive member 62 can be prevented from being separated from the socket 63; on the other hand, the stress in the conductive member 62 can be concentrated in the first positioning structure, thereby avoiding the stress being concentrated at the bend of the conductive member 62, causing the conductive member 62 to deform or break.

[0154] The first positioning structure includes a first protrusion 621 and a first groove 632 . The first protrusion 621 is disposed on one of the conductive member 62 and the socket 63 . The first groove 632 is disposed on the other of the conductive member 62 and the socket 63 . The first protrusion 621 is inserted into the first groove 632 .

[0155] In one embodiment, the first protrusion 621 is disposed on the conductive member 62 , and the first groove 632 is disposed on the socket 63 ; in another embodiment, the first protrusion 621 is disposed on the socket 63 , and the first groove 632 is disposed on the conductive member 62 .

[0156] like Figure 7 and Fig.12 As shown, the outer cover 11 has a slot 111, and the socket 63 is inserted into the slot 111. It is understandable that the socket 63 is engaged with the slot 111 of the outer cover 11, which can improve the stability of the socket 63 and prevent the conductive member 62 from forming a cantilever structure and shaking.

[0157] Please continue reading Figure 7 and Fig.12 A second positioning structure is provided between the outer peripheral surface of the socket 63 and the slot wall of the slot 111. The second positioning structure can play a limiting role to further prevent the socket 63 from shaking. It can be understood that when the external connector is inserted into the socket 63, the force point of the socket 63 is located at the second positioning structure to prevent the conductive member 62 from being deformed due to the excessive cantilever during the assembly process.

[0158] Among them, the second positioning structure includes a second protrusion 633 and a second groove 112, the second protrusion 633 is arranged on one of the groove walls of the socket 63 and the card slot 111; the second groove 112 is arranged on the other groove wall of the socket 63 and the card slot 111, and the second protrusion 633 is inserted into the second groove 112.

[0159] In one embodiment, the second protrusion 633 is disposed on the outer circumference of the socket 63, and the second groove 112 is disposed on the groove wall of the card slot 111; in another embodiment, the second protrusion 633 is disposed on the groove wall of the card slot 111, and the second groove 112 is disposed on the outer circumference of the socket 63.

[0160] like Figure 7As shown, the mounting foot 113 and the slot 631 of the socket 63 are located on the same side of the relay body 20. In the embodiment of the present application, the mounting foot 113 and the slot 631 of the socket 63 are arranged on the same side of the relay body 20, which can improve the space utilization of the relay and avoid unnecessary waste of space.

[0161] Please return to Figure 8 The connecting member 61 is mechanically connected to the coil frame 43. In one embodiment, one of the coil frame 43 and the connecting member 61 has a mounting post 431, and the other has a fixing hole 611, and the mounting post 431 and the fixing hole 611 are interference fit.

[0162] In detail, the first flange 433 of the coil frame 43 is provided with a mounting post 431 , and the connector 61 is provided with a fixing hole 611 ; or, the first flange 433 of the coil frame 43 is provided with a fixing hole 611 , and the connector 61 is provided with a mounting post 431 .

[0163] like Figure 8 and Fig.13 As shown, in addition, the connecting member 61 can also be connected to the U-shaped yoke 47. In one embodiment, one of the U-shaped yoke 47 and the connecting member 61 has a clamping portion 612, and the other has a clamping interface 473, and the clamping portion 612 is clamped into the clamping interface 473.

[0164] In detail, the side yoke plate 472 of the U-shaped yoke 47 has a snap-in interface 473 , and the connector 61 has a snap-in portion 612 ; or, the side yoke plate 472 of the U-shaped yoke 47 has a snap-in portion 612 , and the connector 61 has a snap-in interface 473 .

[0165] It is understandable that the connecting member 61 is also connected to the U-shaped yoke 47, that is, a positioning point is formed at the connection between the two. The positioning point serves as a force point to avoid deformation of the conductive member 62 due to an excessively long cantilever.

[0166] In the embodiment of the present application, the connector 61 is connected to the coil frame 43 and the U-shaped yoke 47 respectively, so that the connector 61 is stably connected to the relay body 20, and the lead-out pins 441 and the auxiliary static contact assembly 82 are led out with a minimum of welding points.

[0167] like Fig.14 and Fig.16 As shown, the similarities between the second embodiment of the present application and the first embodiment are not repeated here, and the differences are as follows:

[0168] The first lead-out piece 71 and the second lead-out piece 72 also jointly form a second notch 74 , which is connected to the first notch 73 ; the orthographic projections of the second notch 74 and the first connecting portion 711 on the first target plane have overlapping third projections.

[0169] In the embodiments of the present application, Fig.14 As shown, the lead-out member 70 also has a second notch 74 , which further reduces the force acting on the first lead-out piece 71 .

[0170] Continue reading Figures 14 to 16 , the orthographic projections of the second connecting portion 721 of the second lead-out piece 72 and the second notch 74 on the second target plane overlap each other; the second target plane is parallel to the first lead-out piece 71, that is, the second target plane is perpendicular to the second direction D2. The orthographic projections of the geometric center of the second connecting portion 721 and the second notch 74 on the second target plane do not overlap each other.

[0171] In the embodiment of the present application, the length of the second notch 74 along the first direction D1 is moderate, which not only minimizes the force acting on the first lead-out piece 71 but also avoids damaging the structural strength between the second lead-out piece 72 and the first lead-out piece 71 .

[0172] like Fig.17 As shown, the similarities between the third embodiment of the present application and the first embodiment are not repeated here, and the differences are as follows:

[0173] The lead-out member 70 is a flat plate structure, that is, the first lead-out piece 71 is arranged in parallel with the second lead-out piece 72. Both side surfaces of the first lead-out piece 71 in the thickness direction are flush with both side surfaces of the second lead-out piece 72 in the thickness direction.

[0174] like Fig.18 As shown, the similarities between the fourth embodiment of the present application and the second embodiment are not repeated here, and the difference lies in that:

[0175] The lead-out member 70 is a flat plate structure, that is, the first lead-out piece 71 is arranged in parallel with the second lead-out piece 72. Both side surfaces of the first lead-out piece 71 in the thickness direction are flush with both side surfaces of the second lead-out piece 72 in the thickness direction.

[0176] In summary, the relay of the embodiment of the present application has at least the following advantages and beneficial effects:

[0177] The lead-out piece 70 of the embodiment of the present application forms a first notch 73 between the first lead-out piece 71 and the second lead-out piece 72, and the first projection of the geometric center of the first connecting portion 711 on the first target plane falls within the second projection of the first notch 73 on the first target plane, thereby reducing the force acting on the first lead-out piece 71, and to a certain extent avoiding the influence of the prying of the first lead-out piece 71 on the firmness of the connection between the first lead-out piece 71 and the static contact 22, and further avoiding the rupture of the insulating cover 21.

[0178] Furthermore, the second lead piece 72 is vertically connected to the first lead piece 71. By bending the second lead piece 72, the installation direction of the second connection portion 721 and the load can be roughly the same as the installation direction of the third mounting hole 1131 of the mounting foot 113 and the plugging and unplugging direction of the external connector, which is convenient for the overall installation of the relay.

[0179] Furthermore, the axis of the second mounting hole 721a is parallel to the plugging direction of the external connector and the slot 631, and is perpendicular to the movement direction of the moving assembly 30, so that the relay is conveniently installed in a horizontal position. At the same time, the axis of the second mounting hole 721a and the plugging direction of the external connector and the slot 631 are consistent, and are perpendicular to the mounting surface 1a of the external device 1, so that the mounting direction of the lead-out piece 70 and the load and the plugging direction of the external connector and the connector assembly 60 are all concentrated in one direction, which is convenient for plugging and unplugging the external connector and the connector assembly 60, and for connecting the lead-out piece 70 to the load through its second mounting hole 721a, which is convenient for the installation of the relay and is conducive to the realization of automated assembly.

[0180] Furthermore, along the first direction D1, the distance W3 between the two second connection parts 721 of the two lead-out members 70 is greater than the distance W4 between the two first connection parts 711. Since the distance between the two second connection parts 721 is larger, the electrical gap is increased, thereby improving safety.

[0181] Furthermore, the connector 61 is mechanically connected to the relay body 20, and the conductive member 62 is electrically connected to the relay body 20, so that the fixed connection between the connector assembly 60 and the relay body 20 is mainly completed through the connector 61, and the conductive member 62 and the relay body 20 mainly play the role of electrical connection. When the relay vibrates, the mechanical connection structure between the connector 61 and the relay body 20 can bear the vibration force, preventing the vibration force from acting on the electrical connection between the conductive member 62 and the relay body 20, resulting in poor electrical connection. In addition, the mechanical connection between the connector 61 and the relay body 20 also has the effect of realizing the lead-out of the lead pin 441 and the auxiliary static contact assembly 82 with the least number of solder joints.

[0182] Furthermore, by providing a first positioning structure between the conductive member 62 and the socket 63, on the one hand, the conductive member 62 can be prevented from being detached from the socket 63; on the other hand, the stress in the conductive member 62 can be concentrated in the first positioning structure, thereby avoiding stress concentration at the bend of the conductive member 62, which may cause deformation or breakage of the conductive member 62.

[0183] Furthermore, a second positioning structure is provided between the outer peripheral surface of the plug socket 63 and the slot wall of the slot 111 , and the second positioning structure can play a limiting role to further prevent the plug socket 63 from shaking.

[0184] Furthermore, a target angle α is formed between the axis of the second mounting hole 1131 of the mounting foot 113 and the movement direction of the dynamic component 30, so that the installation direction of the mounting foot 113, the installation direction of the lead-out member 70 and the load, and the external connector and the connector assembly 60 are all concentrated in one direction and can be installed in the same direction.

[0185] Furthermore, the connector 61, the conductive member 62 and the socket 63 are integrally formed and form an integral part. When installing, it is only necessary to electrically connect the multiple conductive members 62 of the integral part with the lead pin 441 and the auxiliary static contact assembly 82, which is simple to assemble and saves installation space. In addition, when the structure of the relay body 20 remains unchanged, the position of the connector 61 and the bending direction of the conductive member 62 can be adjusted to match the different arrangement positions of the lead pin 441 and the auxiliary static contact assembly 82, and the lead-out direction of the lead-out member 70 and the plug-in direction of the external connector can be flexibly adjusted.
