[0001] This application relates to the field of new energy connector technology, specifically to a multi-branch socket and connector. Background Technology
[0002] In addition to meeting general performance requirements, electrical connectors must also meet the following requirements: good contact, reliable operation, and easy maintenance. Their reliability directly affects the normal operation of the circuit.
[0003] With the development of new energy electric vehicles, the demand for connectors in this field is increasing, and various types of connectors are emerging. Since charging piles on the market do not all use the same charging voltage, they are basically divided into high-voltage and low-voltage types. Currently, electric vehicles on the market have both 500V and 800V voltage platforms. Traditional single sockets can hardly meet the charging needs of both high and low voltages simultaneously. Therefore, designing a socket that can adapt to the charging requirements of both high and low voltages is a problem we need to solve. Summary of the Invention
[0004] The purpose of this application is to provide a multi-branch socket to solve the problem that existing sockets cannot simultaneously meet the needs of high and low voltage charging.

Detailed Implementation
[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Embodiment 1
[0030] As shown in Figures 1 to 6, this embodiment discloses a mounting base plate 1, a connecting component 3, and a fastener 6. The mounting base plate 1 is provided with a DC+ terminal 103, and the DC+ terminal 103 is provided with a first branch 12 and at least one second branch 121. The second branch 121 and the connecting component 3 are provided with a connecting part. The fastener 6 is threaded to the connecting part to fix the second branch 121 and the connecting component 3. The current transmission path can be switched between the first branch 12 and the second branch 121.
[0031] The connecting part includes a threaded structure, which is used with fastener 6 for threaded fixation. The most common type is a bolt with an internal threaded hole.
[0032] In a further embodiment, as shown in Figures 1 and 4, the first branch 12 is cold-forged at the tail end of the DC+ terminal 103. The tail end of the first branch 12 is connected to the power transmission cable via a thread. Specifically, a threaded cap is crimped onto the power transmission cable, and the threaded cap is connected to a nut at the port of the first branch 12. The second branch 121 is set at a 90-degree angle to the first branch 12. This angle is not limited and can be used as long as it is suitable for actual use.
[0033] As shown in Figure 5, in this embodiment, the connecting component 3 includes a first bracket 2, the lower end of which is connected to another power transmission cable, which is ultimately connected to the battery inside the vehicle; the first bracket 2 and the second branch 121 are fixed by fastener 6 threaded engagement.
[0034] When in use, the socket can select different routes according to different voltages. When encountering a charging pile of 700V or above, it charges along the second branch 121, that is, the first bracket 2 and the power transmission cable supply the battery; when encountering a charging pile of ordinary 400V or below, it uses the DC+ terminal 103 and the first branch 12 for charging. During production, mounting holes are opened on both the first bracket 2 and the second branch 121. When the fastener 6 (bolt) is fixed, the axes of the two mounting holes are set on the same line. The second mounting hole of the second branch 121 is also provided with a nut 61 and a bolt.
[0035] In addition, in some design schemes, the second branch 121 is provided with a threaded hole, the first bracket 2 is provided with a first mounting hole, and the bolt thread passes through the first mounting hole and is threaded and locked in the threaded hole; in some embodiments, a crimping plate is used for fastener 6, which requires the use of crimping equipment to fix the connected objects in production, but this connection has strong wrapping properties.
[0036] As shown in Figures 2 and 6, in a further embodiment, the socket also includes an adapter 4, which is detachably connected to the mounting base 1. During the design, the power transmission cable is pre-installed on the adapter 4, which can realize the quick assembly of the socket. The adapter 4 is provided with a guide groove 41, and the first bracket 2 is oriented and connected in the guide groove 41.
[0037] Specifically, as shown in Figures 4 and 6, in this embodiment, the first bracket 2 has two fixed sections 21, which are symmetrically installed on both sides of the first bracket 2. The cross-section of the first bracket 2 is "I" shaped. The guide groove 41 has two positioning ports 42 opposite to each other. The fixed sections 21 are movably placed in the positioning ports 42, and the two fixed sections 21 are movably set on the two positioning ports 42 of the corresponding guide groove 41.
[0038] As shown in Figure 3, in a further embodiment, a second bracket 20 is connected to the first bracket 2, and a cover plate 5 is movably installed on the second bracket 20. The cover plate 5 moves to cover the fastener 6. The movably installed cover plate 5 can cover the installation position of the fastener 6, preventing the entry of external dust and other impurities, reducing the rate of corrosion of the fastener 6, and improving the overall aesthetics of the equipment. Specifically, the second bracket 20 is integrally installed on the side of the first bracket 2 away from the second branch 121. The second bracket 20 is provided with guide parts 201 (slide grooves) on the upper and lower sides, and slide seats 51 are correspondingly provided on the upper and lower sides of the cover plate 5. The two movable bodies 51 (slide seats) and the two guide parts 201 are correspondingly matched and moved. It should be noted that when the cover plate 5 moves to the side of the fastener 6, the distance between the cover plate 5 and the mounting surface of the first bracket 2 needs to be greater than the distance between the fastener 6 and the mounting surface of the first bracket 2 after it is fixed.
[0039] A housing 3 is installed between the first support 2 and the connection point of the power transmission cable. Example 2
[0040] This embodiment discloses a connector, which includes a multi-branch socket as described in the above embodiment, and also includes a plug. When in use, the plug is inserted into the charging port on the multi-branch socket. Here, the charging port is divided into a slow charging port 101 and a fast charging port 102. The DC+ terminal 103 in the above embodiment is fixed in the fast charging port 102. It corresponds to different voltages and realizes different charging route modes. The control execution method belongs to the prior art and will not be described in detail here.
