Description

Technical Field

[0001] This application relates to the field of connectors for new energy electric vehicles, and more specifically, to a connector whose housing does not require additional openings to lock the two copper busbars. Background Technology

[0002] Connectors are important components of new energy electric vehicles, such as Figure 1 As shown, the metal bent connectors currently used in the new energy electric vehicle connector industry adopt the type of design with a flip cover on the shell to lock the two copper busbars. When locking, it is necessary to first install the screws that lock the two copper busbars from the top of the connector, and then tighten the screws from the top of the connector, i.e. the flip cover position, to lock the two copper busbars. Then, install the flip cover mounting plate 1-2, install the flip cover sealing ring 1-3 into the flip cover 1-4 to obtain the flip cover assembly, cover the flip cover assembly, and use screws 1-5 to tighten the flip cover assembly to the shell 1-1 to ensure sealing performance. The flip-top design adds several parts, including flip-top 1-4, flip-top sealing ring 1-3, flip-top mounting plate 1-2, and screws 1-5 for locking the flip-top to the outer shell, increasing costs. The additional flip-top mounting plate 1-2 ensures electrical clearance between the flip-top 1-4 and the screws locking the two copper busbars. A notch is added to the outer shell 1-1 to provide operating space for locking the two copper busbars from the top of the connector, and to enhance the sealing and waterproof design of the flip-top 1-4. During installation, it requires multiple insertions and replacements of assembly parts, making installation and locking inconvenient.

[0003] Therefore, the current connector structure needs to be improved to overcome the above-mentioned defects. Utility Model Content

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 2-4 As shown, a connector that does not require additional openings in the housing to lock two copper busbars includes a housing, a mounting plate that mates with the housing, and a sheath. The mounting plate is provided with a first copper busbar 4, and the sheath is provided with a second copper busbar 14. The connector also includes a locking structure that simultaneously locks the first copper busbar 4 and the second copper busbar 14. The locking structure includes a fastener 6 pre-installed in the mounting plate and a nut 10 pre-installed in the sheath. The locking end of the fastener 6 passes through through holes 7 on the first copper busbar 4 and the second copper busbar 14, respectively, and mates with the nut 10.

[0029] The mounting plate and the sheath are respectively inserted into both ends of the outer shell. To improve the sealing effect, a sealing ring 13 is provided between the mounting plate and the outer shell. The second copper busbar 14 is fixedly connected to a cable assembly. The cable assembly includes a cable body that is welded and fixed to the second copper busbar 14. A waterproof plug 15, a wire clamp 16, and a tail cap 17 are sequentially provided on the cable body. The tail cap 17 is fastened and fixed to the sheath. It should be noted that the fastener 6 is preferably a locking bolt.

[0030] The specific installation process is as follows: Install the fastener 6 and the first copper busbar 4 into the mounting plate, then press them into the outer shell, and then install the sealing ring 13 to obtain the shell 11 assembly; press the nut 10 into the upper sheath 9 to obtain the upper sheath 9 assembly; pre-install the waterproof plug 15, wire clamp 16, and tail cap 17 onto the cable, weld the second copper busbar 14 onto the cable, then install the welded cable into the upper sheath 9 assembly, and then install the lower sheath 12. The upper sheath 9 assembly and the lower sheath 12 are fastened together to fix the second copper busbar 14 to obtain the cable assembly; then push the cable assembly into the shell 11 assembly; tighten the screws from the mounting plate direction with an external hex wrench, and then fasten the tail cap 17.

[0031] The above structure eliminates the need for additional holes in the outer casing to lock the two copper busbars with a flip cover. The two copper busbars can be locked from the mounting plate direction, eliminating the need for flip cover-related parts design. The mounting plate is designed inside the outer casing, and the locking screw assembly is pre-installed in the mounting plate. A hex wrench is used to lock the screws from the connector opening through the mounting plate. The design requires fewer parts, resulting in a lower cost compared to the flip cover design. During installation, there is no need to repeatedly insert or replace parts, making installation and locking more convenient.

[0032] Regarding fastener 6, which is pre-installed within the mounting plate, this improves the original mounting plate structure, such as... Figure 2 As shown, the specific details are as follows: The mounting plate includes a mounting plate body 1, and the mounting plate body 1 has at least one receiving cavity 2 for placing the fastener 6. The opening of the receiving cavity 2 is set upward, and the locking end of the fastener 6 is directly opposite the through hole 7 of the first copper busbar 4. Preferably, two receiving cavities 2 are used. With this structure, the step of installing the fastener 6 is eliminated for the client, making the installation more convenient.

[0033] Furthermore, the key to using pre-installed fasteners 6 lies in ensuring that the locking end of the fastener 6 is aligned with the through hole 7 on the first copper busbar 4. Therefore, the receiving cavity 2 is provided with a limiting structure to limit the fastener 6. Specifically, the limiting structure is a limiting groove 3 opened at the bottom of the receiving cavity 2. The limiting groove 3 cooperates with the operating end of the fastener 6. Therefore, when the fastener 6 is installed into the receiving cavity 2, its operating end falls into the limiting groove 3 that cooperates with it. The limiting groove 3 restricts the fastener 6 so that the locking end of the fastener 6 can be aligned with the through hole 7. In addition, the connection between the receiving cavity 2 and the limiting groove 3 has a guide slope that facilitates the insertion of the operating end of the fastener 6 into the limiting groove 3. This guide slope allows the operating end of the fastener 6 to fall into the limiting groove 3 more smoothly.

[0034] In order to better limit the first copper busbar 4, the mounting plate body 1 is also provided with a cavity 5, and at least part of the first copper busbar 4 is located in the cavity 5.

[0035] To prevent the fastener 6 from falling out of the receiving cavity 2, the size of the operating hole 8 is smaller than the size of the operating end of the fastener 6. In order to lock the two copper busbars, the size of the through hole 7 is larger than the size of the locking end of the fastener 6 and smaller than the size of the operating end of the fastener 6.

[0036] Regarding the nut 10 pre-installed inside the sheath, the structure of the sheath is as follows: the sheath includes an upper sheath 9 and a lower sheath 12. The second copper busbar 14 is fastened and fixed by the upper sheath 9 and the lower sheath 12. An installation groove is provided in the upper sheath 9. The nut 10 is fixedly installed in the installation groove. The way the nut 10 is fixed in the installation groove is not limited. It can be fixed by interference fit or adhesive bonding.

[0037] like Figure 4 As shown, when the client is operating, hex wrench only needs to operate the fastener 6 through the operating hole 8. Its locking end passes through the through hole 7 of the first copper busbar 4 and the second copper busbar 14 in sequence and then cooperates with the nut 10, thus locking the two copper busbars at the same time.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
