Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage connectors, and in particular to a mating type high-voltage connector. Background Technology

[0002] Compared to traditional vehicles, a key characteristic of new energy vehicles is that they are equipped with high-voltage, high-current systems, including charging systems, power distribution systems, and power systems. Electrical connectors are indispensable for the installation, maintenance, and disassembly of these components.

[0003] Currently, high-voltage connectors have a fixed cable exit angle, meaning that the socket on a single type of high-voltage connector can only accommodate a plug with a single cable exit angle. With OEMs demanding standardized and platform-based interfaces, plugs with a single fixed angle are no longer sufficient to meet the requirements and hinder the realization of multi-angle cable exits for high-voltage connectors. Utility Model Content

[0004] To address the shortcomings in the aforementioned background technology, this utility model proposes a mating type high-voltage connector, which solves the technical problem that the socket in existing high-voltage connectors can only be adapted to a type of plug with a fixed outgoing wire angle.

[0005] The technical solution of this utility model is implemented as follows: A plug-in type high-voltage connector includes a socket and a plug that are plugged in. The socket includes a socket body, on which socket terminals and a rectangular support wall are provided. The rectangular support wall is located outside the socket terminals. The plug includes a plug body, on which plug terminals are provided. The plug body includes a fixing part and a connecting part for wire output. The fixing part and the connecting part are integrally connected. The fixing part is provided with a plug groove that is plugged in to cooperate with the rectangular support wall. The included angle between the fixing part and the connecting part is A, 90°≤A≤180°. The socket of this application has a rectangular support wall, and the plug has a fixing part. The fixing part has a plug groove that mates with the rectangular support wall. This allows a socket with a rectangular support wall in the high-voltage connector of this application to be compatible with multiple plugs with plug grooves. At the same time, the included angle between the fixing part and the connecting part on the plug is A, 90°≤A≤180°, which makes the wire exit angle on the plug not fixed. It can be selected between 90° and 180° according to actual needs, which greatly improves the applicability of the high-voltage connector and realizes the purpose of multi-angle wire exit of the high-voltage connector. It solves the technical problem that the socket in the existing high-voltage connector can only be compatible with a plug with a fixed wire exit angle.

[0006] Preferably, one end of the connecting part is connected to the fixing part, and the other end extends towards the front side of the fixing part. This integral connection and fixing of one end of the connecting part to the fixing part, with the other end extending towards the front side of the fixing part, further restricts the position of the wire extending along the connecting part to extend towards the front side of the fixing part, thereby ensuring that the wire exit direction is towards the front side of the fixing part.

[0007] Preferably, one end of the connecting part is connected to the fixing part, and the other end extends toward the rear side of the fixing part. This arrangement, with one end of the connecting part fixed to the fixing part and the other end extending toward the rear side of the fixing part, further restricts the position of the wire extending along the connecting part to extend toward the rear side of the fixing part, thereby ensuring that the wire exit direction is toward the rear side of the fixing part.

[0008] Preferably, one end of the connecting part is connected to the fixing part, and the other end extends towards the left side of the fixing part. This arrangement further restricts the position of the wire extending along the connecting part to the left side of the fixing part, thus ensuring that the wire exiting the connection is directed towards the left side of the fixing part.

[0009] Preferably, one end of the connecting part is connected to the fixing part, and the other end extends towards the right side of the fixing part. This arrangement further restricts the position of the wire extending along the connecting part to the right side of the fixing part, thus ensuring that the wire exit direction is towards the right side of the fixing part.

[0010] Preferably, the socket body is provided with a first fixing block, and a second fixing block is integrally connected to the upper part of the fixing part. The second fixing block is provided with a bolt structure, and the first fixing block and the second fixing block are connected by the bolt structure. The bolt structure is provided to achieve a fixed connection between the socket and the plug. A pre-embedded nut is pre-embedded in the first fixing block, and the fixed connection between the socket and the plug is achieved by the threaded connection between the bolt structure and the pre-embedded nut on the first fixing block.

[0011] Preferably, a CPA (Constant Anchor Pad) for secondary fixation is provided between the socket and the plug. The CPA is symmetrically arranged with the bolt structure. A third fixing block is provided on the socket body, and a stop block is provided on the third fixing block. The CPA engages with the stop block. The CPA is provided to achieve secondary fixation between the socket and the plug. Primary fixation between the socket and the plug is achieved by the threaded connection between the bolt structure and the pre-embedded nut on the first fixing block; secondary fixation is achieved by the engagement of the CPA with the stop block.

[0012] The preferred third fixing block and the first fixing block have the same structure and are symmetrically arranged on the socket body. Both the third fixing block and the first fixing block are provided with a stop block and a pre-embedded nut is pre-embedded on both the third fixing block and the first fixing block. When the socket and the plug are fixedly connected by the bolt structure and the pre-embedded nut on the first fixing block, the CPA is engaged with the stop block on the third fixing block.

[0013] The CPA and bolt structure are located on two opposite sides of the high-voltage connector. The socket and plug are fixed on the two opposite sides of the high-voltage connector by the CPA and bolt structure, which greatly improves the fixing strength between the socket and plug.

[0014] Preferably, a CPA (Constant Anchor Pad) for secondary fixation is provided between the socket and the plug. The CPA is symmetrically arranged with the bolt structure. A third fixing block is provided on the socket body, and a stop block is provided on the third fixing block. The CPA engages with the stop block. The CPA is provided to achieve secondary fixation between the socket and the plug. Primary fixation between the socket and the plug is achieved by the threaded connection between the bolt structure and the pre-embedded nut on the first fixing block; secondary fixation is achieved by the engagement of the CPA with the stop block.

[0015] The preferred third fixing block and the first fixing block have the same structure and are symmetrically arranged on the socket body. Both the third fixing block and the first fixing block are provided with a stop block and a pre-embedded nut is pre-embedded on both the third fixing block and the first fixing block. When the socket and the plug are fixedly connected by the bolt structure and the pre-embedded nut on the first fixing block, the CPA is engaged with the stop block on the third fixing block.

[0016] The CPA and bolt structure are located on two opposite sides of the high-voltage connector. The socket and plug are fixed on the two opposite sides of the high-voltage connector by the CPA and bolt structure, which greatly improves the fixing strength between the socket and plug.

[0017] Preferably, a limiting bracket is provided on the side wall of the fixing part, and the CPA is inserted into the limiting bracket. The limiting bracket is provided with a primary positioning hole and a secondary positioning hole that can be adapted to the CPA respectively. The limiting bracket is set to fix the position of the CPA. The primary positioning hole is set to limit and fix the CPA in the initial position, and the secondary positioning hole is set to limit and fix the CPA in the final position. It should be noted that the CPA is provided with a cantilever, and a positioning block is integrally connected to the cantilever. When the positioning block is inserted into the primary positioning hole, the CPA is limited and fixed in the initial position. At this time, the CPA is not engaged with the stop block. When the positioning block is inserted into the secondary positioning hole, the CPA is limited and fixed in the final position. At this time, the CPA is engaged with the stop block.

[0018] Preferably, the rectangular support wall is provided with guide blocks, and the insertion slot is provided with guide grooves. The guide blocks and guide grooves are engaged in a plug-in fit. The engagement of the guide blocks and guide grooves guides the plug-in fit between the socket and the plug, reducing the possibility of misalignment during plug-in, and facilitating the rapid assembly of the high-voltage connector. At least two guide blocks are provided on the rectangular support wall, and the at least two guide blocks are symmetrically arranged on the rectangular support wall. The presence of at least two guide blocks on the rectangular support wall and corresponding guide grooves in the insertion slots, with one guide block and one guide groove, and the symmetrical arrangement of the guide grooves on the rectangular support wall, greatly reduces the possibility of misalignment during plug-in.

[0019] Preferably, the second fixing block is provided with a bushing to prevent the bolt structure from falling off. The bolt structure includes an integrally connected bolt head, a smooth shank, and a threaded shank. The outer diameter of the threaded shank is larger than that of the smooth shank. The bushing is provided with an axially arranged through hole and a threaded hole, which communicate with each other. The threaded shank is threadedly connected to the threaded hole, which is located above the through hole. The bushing can be pre-embedded in the mounting hole on the second fixing block. During bolt structure installation, the threaded shank first spirals through the threaded hole and extends into the through hole, at which point the smooth shank passes through the threaded hole. The threaded shank on the bolt structure allows the bolt structure to be pre-installed on the second fixing block of the plug, and the threaded connection between the threaded shank and the threaded hole ensures that the bolt structure will not fall off naturally. After the socket and plug are mated, the socket and plug are fixed by the threaded connection between the threaded shank on the bolt structure and the pre-embedded nut on the first or third fixing block.

It can be selected between 90° and 180° according to actual needs, which greatly improves the applicability of the high-voltage connector and realizes the purpose of multi-angle wire exit of the high-voltage connector.

[0021] 2. The rectangular support wall of this application is provided with a guide groove, and a guide block is provided in the plug groove.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] in Figure 1 The included angle between the fixing part 7 and the connecting part 8 is A, where A is 90°. Figure 2 The included angle between the fixing part 7 and the connecting part 8 is A, where A is 150°. Figure 3 The included angle between the fixing part 7 and the connecting part 8 is A, where A is 180°. Figure 1 and Figure 2 One end of the connecting part 8 is connected and fixed to the fixing part 7, and the other end extends toward the left side of the fixing part 7.

[0037] Example 1: A mating type high-voltage connector, such as...

At the same time, the included angle between the fixing part 7 and the connecting part 8 on the plug 2 is A, 90°≤A≤180°, so that the wire exit angle on the plug 2 is not fixed and can be selected between 90° and 180° according to actual needs.

Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, one end of the connecting part 8 is connected to the fixing part 7, and the other end extends toward the right side of the fixing part 7.

[0048] Example 10, based on Example 9, provides a mating type high-voltage connector, such as... Figure 6 , Figure 7 , Figure 10 and Figure 11 As shown, the second fixing block 11 is provided with a bushing 23 to prevent the bolt structure 12 from falling off. The bolt structure 12 includes an integrally connected bolt head, a smooth rod portion 26, and a threaded rod portion 27.

When the bolt structure 12 is installed, the threaded rod portion 27 on the bolt structure 12 first spirals through the threaded hole 25 and extends into the through hole 24. At this time, the smooth rod portion 26 on the bolt structure 12 passes through the threaded hole 25. The setting of the threaded rod portion 27 on the bolt structure 12 allows the bolt structure 12 to be pre-installed on the second fixing block 11 of the plug 2, and the threaded connection between the threaded rod portion 27 and the threaded hole 25 ensures that the bolt structure 12 will not fall off naturally. After the socket 1 and plug 2 are plugged in, the socket 1 and plug 2 are fixed by threading the screw part 27 on the bolt structure 12 to the pre-embedded nut 21 on the first fixing block 10 or the third fixing block 13.

[0049] In Example 10, the socket terminal 4 is installed onto the molded socket 1. Then, the corresponding plug 2 is selected according to the actual outgoing angle and direction of the wire. The plug terminal and CPA16 are then installed onto the molded plug 2 in sequence. At this time, the positioning block 22 on CPA16 is inserted into the primary positioning hole 17 of the limiting frame 15, and CPA16 is limited and fixed in the initial position. Then, pre-embedded nuts 21 are pre-embedded on the first fixing block 10 and the third fixing block 13, and a bushing 23 is pre-embedded on the second fixing block 11. The bolt structure 12 passes through the bushing 23 to realize the bolt structure. The socket 1 and plug 2 are pre-installed, and then the socket 1 and plug 2 are inserted into each other. After insertion, the socket 1 and plug 2 are fixed by threading the bolt structure 12 to the pre-embedded nut 21 on the first fixing block 10. By pushing CPA16, the positioning block 22 on CPA16 moves from the primary positioning hole 17 to the secondary positioning hole 20 of the limit frame 15. CPA16 is limited and fixed in the final position. At this time, the CPA16 and the stop block 14 on the third fixing block 13 are engaged to achieve secondary fixation of socket 1 and plug 2, thus completing the assembly of the high voltage connector of this application.
