Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a connector and an electrical protection device. Background Art

[0002] An electrical protection device is a device used to protect electrical equipment and power systems. It is usually composed of multiple modules with different functions, such as electrical signal acquisition module, fault detection module, and protection module. Connectors are generally used to connect the protection modules instead of wires, which makes the connection and installation between the modules more reliable.

[0003] The connector is usually provided with a cover to protect the wiring portion of the connector. In the prior art, the cover is not firmly fixed to the housing of the connector, and the cover is easily dropped from the housing when shaking or bumping occurs. Utility Model Content

[0004] The present application provides a connector and an electrical protection device, which can improve the stability of fixing a cover on a housing.

[0005] In a first aspect, the present application provides a connector, comprising: a shell and a cover. The shell comprises a wiring portion, and the shell is provided with a first mounting structure and a second mounting structure that are different from each other. The cover shields the wiring portion, and the cover is provided with a first matching structure and a second matching structure that are different from each other, the first matching structure is adapted to the first mounting structure, and the second matching structure is adapted to the second mounting structure. The first matching structure is connected to the first mounting structure, and the second matching structure is connected to the second mounting structure, so as to connect the cover to the shell, and limit the cover from at least two directions.

[0006] Through the above scheme, a first mounting structure and a second mounting structure that are different from each other are set on the shell, and a first matching structure and a second matching structure that are different from each other are set on the cover, and the first mounting structure is adapted to the first matching structure, and the second mounting structure is adapted to the second matching structure. Based on this, when the first matching structure is connected to the first mounting structure, and the second matching structure is connected to the second mounting structure, on the one hand, the cover can be firmly fixed to the shell, reducing the possibility of the cover falling off the shell due to shaking or bumping of the shell.

[0007] On the other hand, when the first mounting structure is connected to the first matching structure, the cover body can be limited in at least one direction. When the second mounting structure is connected to the second matching structure, the cover body can be limited in at least another direction. The one direction is different from the other direction. Therefore, the connection method between the shell and the cover body can limit the cover body in at least two directions, rather than limiting the cover body in only one direction, thereby improving the stability of the cover body fixed to the shell and reducing the possibility of the cover body falling off from the shell.

[0008] In a possible design, the wiring portion is provided with a mounting hole along a first direction, and the mounting hole is used to install a clamping screw. The at least two directions include a first direction and a second direction, and the second direction is perpendicular to the first direction.

[0009] Through the above solution, the installation hole is provided in the wiring part, which can facilitate the user to operate the clamping screw. More importantly, the at least two directions include a first direction and a second direction, and the first direction is perpendicular to the second direction, so that the shell and the cover can be fastened and connected not only in the extension direction parallel to the installation hole, but also in other directions different from the extension direction, thereby improving the stability of the cover fixed to the shell.

[0010] In a possible design, the cover body includes a first plate and a second plate connected to each other, the first plate is parallel to the first direction, and the second plate is perpendicular to the first direction. The first matching structure is provided on the first plate and / or the second plate along the first direction, and the first matching structure is connected to the first mounting structure, and can limit the cover body in the second direction. The second matching structure is provided on the second plate along the first direction, and the second matching structure is connected to the second mounting structure, and can limit the cover body in the first direction.

[0011] Through the above scheme, the present application does not limit the shape of the cover body, and only needs to meet the requirement that when the cover body is connected to the shell, the cover body can cover the wiring part. In addition, the present application does not limit the setting position of the first matching structure and the second matching structure, and only needs to meet the requirement that when the first matching structure is connected to the first installation structure, the cover body can be limited in one direction, and when the second matching structure is connected to the second installation structure, the cover body can be limited in another direction. In this way, no matter how the first matching structure and the second matching structure are set, it can be ensured that the cover body is limited in both the first direction and the second direction.

[0012] In a possible design, the cover body includes a first plate and a second plate connected to each other, the first plate is parallel to the first direction, and the second plate is perpendicular to the first direction. The first matching structure is provided on the first plate and / or the second plate along the second direction, and the second matching structure is connected to the second mounting structure, and can limit the cover body in the first direction. The second matching structure is provided on the first plate along the second direction, and the second matching structure is connected to the second mounting structure, and can limit the cover body in the second direction.

[0013] Through the above scheme, the present application does not limit the shape of the cover body, and only needs to meet the requirement that when the cover body is connected to the shell, the cover body can cover the wiring part. In addition, the present application does not limit the setting position of the first matching structure and the second matching structure, and only needs to meet the requirement that when the first matching structure is connected to the first installation structure, the cover body can be limited in one direction, and when the second matching structure is connected to the second installation structure, the cover body can be limited in another direction. In this way, no matter how the first matching structure and the second matching structure are set, it can be ensured that the cover body is limited in both the first direction and the second direction.

[0014] In a possible design, the first mounting structure is a slide groove provided on the housing, and the first matching structure is a slider provided on the cover. Alternatively, the first mounting structure is a slider provided on the housing, and the first matching structure is a slide groove provided on the cover.

[0015] Through the above scheme, the connection method between the first mounting structure and the first matching structure is set as the cooperation between the slider and the slide groove, which can not only reduce the manufacturing difficulty of the first mounting structure and the first matching structure, but also the cooperation between the slider and the slide groove can also play a guiding role for the cover body when the cover body is installed on the shell, while ensuring the limitation of the cover body, it also reduces the installation difficulty of the cover body.

[0016] In a possible design, a first limiting protrusion is provided on the side wall of the slider, a first limiting groove is provided on the groove wall of the slide groove at a position opposite to the first limiting protrusion, and the first limiting protrusion is at least partially located in the first limiting groove.

[0017] Through the above scheme, a first limiting groove is set on the groove wall of the slide groove, and a first limiting protrusion is set on the side wall of the slider, and when the cover body is installed on the shell, the first limiting protrusion is at least partially located in the first limiting groove, so that the cover body is limited in the other two directions perpendicular to the first direction.

[0018] In a possible design, the second mounting structure is a slot provided on the housing, and the second matching structure is a block provided on the cover. Alternatively, the second mounting structure is a block provided on the housing, and the second matching structure is a slot provided on the cover.

[0019] Through the above scheme, the connection method between the second installation structure and the second matching structure is set to the matching of the card block and the card slot, which can reduce the manufacturing difficulty of the second installation structure and the second matching structure, and at the same time, can also make the connection between the second installation structure and the second matching structure simpler.

[0020] In one possible design, the number of the first mounting structure, the second mounting structure, the first matching structure and the second matching structure is the same and multiple, the multiple first mounting structures correspond one-to-one to the multiple first matching structures, and the multiple second mounting structures correspond one-to-one to the multiple second matching structures.

[0021] Through the above scheme, the number of the first mounting structure, the second mounting structure, the first matching structure and the second matching structure is set to be the same and multiple, which can increase the strength of the connection between the cover body and the shell, and avoid the connection between the cover body and the shell being affected when a single first mounting structure or second mounting structure or first matching structure or second matching structure is aged or damaged. Make multiple first mounting structures correspond to multiple first matching structures one by one, and multiple second mounting structures correspond to multiple second matching structures one by one, which can increase the connection stability between the first mounting structure and the first matching structure, and at the same time, can increase the connection stability between the second mounting structure and the second matching structure.

[0022] In a possible design, the wiring portion is provided with a second limiting groove, and the cover body is provided with a second limiting protrusion at a position corresponding to the second limiting groove, and the second limiting protrusion is adapted to the second limiting groove.

[0023] Through the above solution, a second limiting groove is provided on the wiring portion, and a second limiting protrusion is provided on the cover body, which can further increase the limiting effect of the shell on the cover body, thereby further increasing the stability of the connection between the cover body and the shell.

[0024] In a second aspect, the present application provides an electrical protection device, comprising a protection component, an electrical switch and the connector in the first aspect. The electrical switch and the protection component are both electrically connected to the connector.

[0025] Through the above scheme, in the electrical protection device, the connecting piece mentioned in the first aspect is arranged, and the cover body in the connecting piece can be limited in at least two directions, thereby improving the stability of the connection between the cover body and the shell in the connecting piece, and solving the problem in the prior art that the cover body on the connecting piece can only be fixed on the shell in a single direction, thereby causing an unreliable connection between the cover body and the shell.

[0026] The beneficial effects of the electrical protection device provided in the second aspect can be referred to the beneficial effects brought about by the first aspect and the various possible implementation methods of the first aspect, and will not be repeated here.

[0050] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0051] The embodiment of the present application provides an electrical protection device, which includes a protection component, an electrical switch and a connector. The electrical switch and the protection component are both electrically connected to the connector.

[0052] An electrical protection device is a device used to protect electrical equipment and power systems. Its main function is to monitor parameters such as current, voltage, frequency, etc. in the electrical system, detect faults in the electrical system in a timely manner, and protect electrical equipment and power systems from damage by controlling power supply or cutting off circuits.

[0053] A motor protection component is a component used to protect a motor or engine. The motor protection component can monitor the load, temperature and other parameters of the motor or engine, and disconnect the circuit when the preset value is reached to protect the motor or engine from damage.

[0054] An electrical switch is a device used to control a circuit and is widely used in various electrical equipment and systems. It can open or close the flow of current in the circuit, ensuring the normal operation and safety of electrical equipment.

[0055] The Ma Bao assembly and the electrical switch are often connected through a connector. The connector includes a wiring part and a cover body, and the cover body is used to protect the wiring part. In the related art, the cover body and the housing of the connector are connected only by a slot and a buckle fit, so that the cover body can only be fixed on the housing in a single direction, resulting in the problem of unreliable connection between the cover body and the housing. When the connector shakes or bumps, the cover body is easy to fall off from the housing.

[0056] Based on this, the present application improves the structure of the connecting piece in order to increase the stability of the connection between the shell and the cover.

[0057] The connector provided in this application is explained in detail below with reference to the accompanying drawings.

Figure 2 A schematic diagram of the structure of the connecting member provided in an embodiment of the present application from another perspective. Figure 3 A schematic diagram of the structure of the cover provided in an embodiment of the present application at a certain viewing angle. Figure 4 This is a schematic structural diagram of the shell provided in an embodiment of the present application at a first viewing angle.

[0059] like Figures 1 to 4 As shown, the present application provides a connector, including: a shell 100 and a cover 200. The shell 100 includes a wiring portion 110, and the shell 100 is provided with a first mounting structure 120 and a second mounting structure 130 that are different from each other. The cover 200 is shielded from the wiring portion 110, and the cover 200 is provided with a first matching structure 210 and a second matching structure 220 that are different from each other, the first matching structure 210 is adapted to the first mounting structure 120, and the second matching structure 220 is adapted to the second mounting structure 130. The first matching structure 210 is connected to the first mounting structure 120, and the second matching structure 220 is connected to the second mounting structure 130, so as to connect the cover 200 to the shell 100, and limit the cover 200 from at least two directions.

[0060] The housing 100 is usually made of insulating material, and a conductive member is disposed inside the housing 100. One side of the housing 100 may be a stepped structure, and the connection portion 110 is disposed at the stepped structure, and the connection portion 110 is used to connect the conductive member inside the housing 100 with the conductive member outside the housing 100.

[0061] Both the first mounting structure 120 and the second mounting structure 130 can be connection structures provided on the housing 100. The first mounting structure 120 and the second mounting structure 130 can be integrally formed with the housing 100 when the housing 100 is molded. Alternatively, the first mounting structure 120 and the second mounting structure 130 can also be separately formed and then assembled with the housing 100. Alternatively, the first mounting structure 120 and the second mounting structure 130 can also be provided on the housing 100 by processes such as cutting and engraving after the housing 100 is molded. The first mounting structure 120 and the second mounting structure 130 are different from each other.

[0062] The cover 200 is usually made of an insulating material. The cover 200 can be made of the same material as the housing 100, or the cover 200 can also be made of a material different from that of the housing 100. The cover 200 can be in the shape of "|", "L", or "匚", etc. The shape of the cover 200 can be determined according to the shape of the wiring part 110, and the size of the cover 200 can be determined according to the size of the wiring part 110.

[0063] Both the first mating structure 210 and the second mating structure 220 can be connection structures provided on the cover 200. The first mating structure 210 and the second mating structure 220 can be integrally formed with the cover 200 when the cover 200 is molded. Alternatively, the first mating structure 210 and the second mating structure 220 can be separately formed and then assembled with the cover 200. Alternatively, the first mating structure 210 and the second mating structure 220 can also be provided on the cover 200 by processes such as cutting and engraving after the cover 200 is molded. The first mating structure 210 and the second mating structure 220 are different from each other.

[0064] The first mating structure 210 is adapted to the first mounting structure 120. When the first mating structure 210 is connected to the first mounting structure 120, the cover 200 and the housing 100 can be connected through the first mating structure 210 and the first mounting structure 120. There are various choices for the mating manner between the first mating structure 210 and the first mounting structure 120, such as pin connection or sliding connection, etc. After the first mating structure 210 is connected to the first mounting structure 120, the cover 200 can be limited in position at least from one direction. Based on this, the positions of the cover 200 and the housing 100 are relatively fixed in this at least one direction.

[0065] The second matching structure 220 is adapted to the second mounting structure 130. When the second matching structure 220 is connected to the second mounting structure 130, the cover 200 and the housing 100 can be connected through the second matching structure 220 and the second mounting structure 130. Similarly, there are also multiple options for the matching method between the second matching structure 220 and the second mounting structure 130, such as: locking connection or lock connection. After the second matching structure 220 is connected to the second mounting structure 130, the cover 200 can be limited in at least another direction. Based on this, the positions of the cover 200 and the housing 100 in the at least another direction are relatively fixed.

[0066] In summary, the present application sets mutually different first mounting structures 120 and second mounting structures 130 on the housing 100, and sets mutually different first matching structures 210 and second matching structures 220 on the cover 200, and the first mounting structure 120 is adapted to the first matching structure 210, and the second mounting structure 130 is adapted to the second matching structure 220. Based on this, when the first matching structure 210 is connected to the first mounting structure 120, and the second matching structure 220 is connected to the second mounting structure 130, on the one hand, the cover 200 can be firmly fixed to the housing 100, reducing the possibility of the cover 200 falling off from the housing 100 due to shaking or bumping of the housing 100.

[0067] On the other hand, when the first mounting structure 120 is connected to the first matching structure 210, the cover body 200 can be limited in at least one direction. When the second mounting structure 130 is connected to the second matching structure 220, the cover body 200 can be limited in at least another direction. The one direction is different from the other direction. Therefore, the connection method between the shell 100 and the cover body 200 can limit the cover body 200 in at least two directions, rather than limiting the cover body 200 in only a single direction, thereby improving the stability of the cover body 200 fixed to the shell 100 and reducing the possibility of the cover body 200 falling off from the shell 100.

[0068] Figure 5 This is a schematic diagram of the structure of the housing 100 provided in the embodiment of the present application at a second viewing angle. Figure 4 as well as Figure 5 As shown, the wiring portion 110 is provided with a mounting hole 111 along the first direction OX, and the mounting hole 111 is used to install a clamping screw. The at least two directions include the first direction OX and the second direction, and the second direction is perpendicular to the first direction OX.

[0069] The mounting hole 111 is a through hole provided on the wiring portion 110. The mounting hole 111 may be a circular hole or a square hole, etc. The mounting hole 111 is used to install a clamping screw, which can fix the external conductive member when the external conductive member is connected to the wiring portion 110, so that the external conductive member will not fall off from the wiring portion 110 easily.

[0070] The first direction OX is consistent with the extension direction of the mounting hole 111. In the spatial coordinate system, there are two directions perpendicular to the first direction. In this application, the second direction is perpendicular to the first direction OX. The second direction can be any direction perpendicular to the first direction.

[0071] Through the above configuration, the installation hole 111 is provided on the wiring portion 110, which can facilitate the user to operate the compression screw. More importantly, the at least two directions include the first direction OX and the second direction, and the first direction OX is perpendicular to the second direction, so that the housing 100 and the cover 200 can be fastened and connected not only in the extension direction parallel to the installation hole 111, but also in other directions different from the extension direction, thereby improving the stability of the cover 220 fixed to the housing 100.

[0072] Please continue to refer to Figure 1 as well as Figure 3 As shown, the cover 200 includes a first plate 230 and a second plate 240 connected to each other, the first plate 230 is parallel to the first direction OX, and the second plate 240 is perpendicular to the first direction OX.

[0073] The first plate 230 may be plate-shaped, and similarly, the second plate 240 may also be plate-shaped, one side of the first plate 230 is connected to one side of the second plate 240, and the first plate 230 and the second plate 240 are perpendicular to each other. The first plate 230 and the second plate 240 may be integrally formed, or the first plate 230 and the second plate 240 may be manufactured separately and then assembled.

[0074] The size of the first plate 230 can be the same as the size of one cross section of the wiring portion 110, or the size of the first plate 230 can be slightly larger than the size of one cross section of the wiring portion 110. The size of the second plate 240 can be the same as the cross section of one side of the wiring portion 110 with the mounting hole 111, or the size of the second plate 240 can be slightly larger than the cross section of one side of the wiring portion 110 with the mounting hole 111. The second plate 240 is provided with a through hole opposite to the mounting hole 111 for an external conductive member to pass through.

[0075] The present application does not limit the shape of the cover 200 , and it only needs to satisfy the requirement that the cover 200 can cover the wiring portion 110 when the cover 200 is connected to the housing 100 .

[0076] In a possible design, the first matching structure 210 is provided on the first plate 230 and / or the second plate 240 along the first direction OX, and the first matching structure 210 is connected to the first mounting structure 120, and can limit the cover body 200 in the second direction. The second matching structure 220 is provided on the second plate 240 along the first direction OX, and the second matching structure 220 is connected to the second mounting structure 130, and can limit the cover body 200 in the first direction OX.

[0077] The first mating structure 210 may be connected only to the first plate 230 , or the first mating structure 210 may be connected only to the second plate 240 , or the first mating structure 210 may be connected to both the first plate 240 .

[0078] The second matching structure 220 can be connected to the second plate 240. The second matching structure 220 can be spaced apart from the first matching structure 210. By increasing the distance between the second matching structure 220 and the first matching structure 210, the limiting area can be increased, so that when the cover 200 and the housing 100 are connected, the stability of the connection between the cover 200 and the housing 100 can be increased.

[0079] In another possible design, the first matching structure 210 is provided on the first plate 230 and / or the second plate 240 along the second direction, and the second matching structure 220 is connected to the second mounting structure 130, so as to limit the cover body 200 in the first direction OX. The second matching structure 220 is provided on the first plate 230 along the second direction, and the second matching structure 220 is connected to the second mounting structure 130, so as to limit the cover body 200 in the second direction.

[0080] The present application does not limit the setting positions of the first matching structure 210 and the second matching structure 220. It only needs to meet the requirement that when the first matching structure 210 is connected to the first mounting structure 120, the cover body 200 can be limited in one direction, and when the second matching structure 220 is connected to the second mounting structure 130, the cover body 200 can be limited in other different directions.

[0081] In summary, no matter how the first matching structure 210 and the second matching structure 220 are arranged, it can be ensured that the cover 200 is limited in both the first direction OX and the second direction.

Figures 3 to 6As shown, the first mounting structure 120 may be a slide groove provided on the housing 100, and the first matching structure 210 may be a slider provided on the cover 200. Alternatively, the first mounting structure 120 may be a slider provided on the housing 100, and the first matching structure 210 may be a slide groove provided on the cover 200.

[0083] The slide groove can be a square groove or an arc groove, etc. When the slide groove is a square groove, the slider is a prism, and when the slide groove is an arc groove, the slider is an arc column. The slider and the slide groove are interference fit to increase the stability of the connection between the cover body 200 and the housing 100 when the cover body 200 is connected to the housing 100.

[0084] Through the above-mentioned settings, the connection method between the first mounting structure 120 and the first matching structure 210 is set as the cooperation between the slider and the slide groove, which can not only reduce the manufacturing difficulty of the first mounting structure 120 and the first matching structure 210, but also the cooperation between the slider and the slide groove can also play a guiding role for the cover body 200 when the cover body 200 is installed on the shell 100, while ensuring the limitation of the cover body 200, it also reduces the installation difficulty of the cover body 200.

[0085] Figure 7 This is a schematic diagram of the structure of the cover provided in the embodiment of the present application from another perspective. Figure 8 for Figure 4 In the enlarged view of the A part, when the cover 200 is connected to the housing 100 through the slide groove and the slider, further, as shown in FIG. Figures 3 to 8 As shown, the side wall of the slider may be provided with a first limiting protrusion 300 , and the groove wall of the slide groove may be provided with a first limiting groove 400 at a position opposite to the first limiting protrusion 300 , and the first limiting protrusion 300 is at least partially located in the first limiting groove 400 .

[0086] The first limiting protrusion 300 is a protrusion provided on the side wall of the slider. The number of the first limiting protrusion 300 may be one or more. Accordingly, when the number of the first limiting protrusion 300 is one, the number of the first limiting groove 400 may be one. When the number of the first limiting protrusion 300 is more than one, the number of the first limiting groove 400 may be more than one, and the more than one first limiting groove 400 may correspond to the more than one first limiting protrusion 300.

[0087] The first limiting protrusion 300 can be arranged at the edge of the side wall of the slider, or at the middle of the side wall of the slider. Correspondingly, the first limiting groove 400 can be arranged at the edge of the groove wall of the slide slot, or at the middle of the groove wall of the slide slot. As long as the first limiting protrusion 300 can be at least partially located in the first limiting groove 400, the connection between the cover body 200 and the housing 100 can be reinforced, and the embodiment of the present application is not limited to this.

[0088] Through the above-mentioned arrangement, a first limiting groove 400 is provided on the groove wall of the slide groove, and a first limiting protrusion 300 is provided on the side wall of the slider, and when the cover body 200 is installed on the shell 100, the first limiting protrusion 300 is at least partially located in the first limiting groove 400, so that the cover body 200 is limited in the other two directions perpendicular to the first direction OX.

[0089] Fig. 9 This is a schematic diagram of the structure of the housing provided in the embodiment of the present application at a third viewing angle. Figure 2 as well as Fig. 9 As shown, the second mounting structure 130 may be a slot provided on the housing 100, and the second matching structure 220 may be a block provided on the cover 200. Alternatively, the second mounting structure 130 may be a block provided on the housing 100, and the second matching structure 220 may be a slot provided on the cover 200.

[0090] The card slot can be a square slot, which can be integrally formed with the shell 100 when the shell 100 is manufactured, or can be set on the shell 100 by cutting or other methods after the shell 100 is manufactured. Alternatively, the card slot can be integrally formed with the cover body 200 when the cover body 200 is manufactured, or can be set on the cover body 200 by cutting or other methods after the cover body 200 is manufactured.

[0091] The card block is in the shape of a long strip, one end of which can be connected to the cover 200 or the housing 100, and the other end of which is chamfered so that the card block can be more conveniently matched with the card slot. The card block can be integrally formed with the cover 200 or the housing 100, or the card block can be manufactured separately and then installed on the cover 200 or the housing 100.

[0092] Through the above-mentioned setting, the connection method between the second mounting structure 130 and the second matching structure 220 is set to the matching of the card block and the card slot, which can reduce the manufacturing difficulty of the second mounting structure 130 and the second matching structure 220, and at the same time, can also make the connection between the second mounting structure 130 and the second matching structure 220 simpler.

[0093] The present application does not limit the setting positions of the second mounting structure 130 and the second matching structure 220 . It only needs to ensure that the cover body 200 can be fixed on the shell 100 when the second mounting structure 130 and the second matching structure 220 are connected.

[0094] In one possible design, the number of the first mounting structure 120, the second mounting structure 130, the first mating structure 210, and the second mating structure 220 can be the same and multiple, and the multiple first mounting structures 120 correspond one-to-one to the multiple first mating structures 210, and the multiple second mounting structures 130 correspond one-to-one to the multiple second mating structures 220.

[0095] Through the above arrangement, the number of the first mounting structure 120, the second mounting structure 130, the first matching structure 210, and the second matching structure 220 is set to be the same and multiple, which can increase the strength of the connection between the cover body 200 and the housing 100, and avoid the connection between the cover body 200 and the housing 100 being affected when a single first mounting structure 120 or second mounting structure 130 or first matching structure 210 or second matching structure 220 is aged or damaged. By making multiple first mounting structures 120 correspond to multiple first matching structures 210 one by one, and multiple second mounting structures 130 correspond to multiple second matching structures 220 one by one, the connection stability between the first mounting structure 120 and the first matching structure 210 can be increased, and at the same time, the connection stability between the second mounting structure 130 and the second matching structure 220 can be increased.

[0096] like Figure 3 as well as Figure 5 As shown, the wiring portion 110 is provided with a second limiting groove 112 , and the cover body 200 is provided with a second limiting protrusion 250 corresponding to the second limiting groove 112 , and the second limiting protrusion 250 is adapted to the second limiting groove 112 .

[0097] The second limiting groove 112 may be arranged along the first direction OX. The second limiting groove 112 is a through groove, which ensures that the groove wall of the second limiting groove 112 will not block the mounting hole 111 .

[0098] The second limiting protrusion 250 is disposed on a side of the cover body 200 facing the mounting hole 111 , and the second limiting protrusion 250 is provided with a through hole corresponding to the position of the mounting hole 111 , so that an external conductive member can pass through the cover body 200 and be connected to the mounting hole 111 .

[0099] Through the above configuration, the second limiting groove 112 is provided on the wiring portion 110, and the second limiting protrusion 250 is provided on the cover body 200, so that the limiting effect of the housing 100 on the cover body 200 can be increased, thereby further increasing the stability of the connection between the cover body 200 and the housing 100. When the cover body 200 is installed on the housing 100, the cooperation between the second limiting groove 112 and the second limiting protrusion 250 can also play a guiding role for the cover body 200.
