Description

Technical Field

[0001] This utility model relates to the field of high-voltage connector technology, specifically a replaceable high-voltage connector. Background Technology

[0002] High-voltage connectors are key components in new energy vehicles and power systems, mainly used for the transmission and connection of high voltage and high current. Replaceable high-voltage connectors are modular electrical connection devices, whose core feature is that they enable the rapid replacement of key components through standardized interfaces and detachable structures.

[0003] High-voltage connectors require high-voltage interlocking during use. The high-voltage interlocking is a crucial component, controlling the continuity of the circuit. High-voltage connectors mainly fall into two categories: direct-insertion high-voltage connectors and crimp-type high-voltage connectors. Customers can choose according to their specific needs. Both types include a male connector, a female connector, and a high-voltage interlocking. The high-voltage interlocking controls whether the male and female connectors are conductive. The high-voltage interlocking and the male connector are integrated into a single unit. This integrated unit, when connected to the female connector, constitutes the high-voltage connector.

[0004] For example, patent CN218242353U discloses a replaceable high-voltage connector. It includes a male connector, connecting groove, slot, fixing groove, limiting groove, limiting strip, high-voltage interlock, female connector, movable frame, connecting seat, and dustproof plate. This allows operators to replace the high-voltage interlock according to actual needs, improving equipment performance and reducing manufacturing costs.

[0005] During use, the wiring connected to one end of the high-voltage lock is directly connected to the slot of the male connector body via the high-voltage interlock. If the wiring is pulled during use, it may affect the stability of the connection between the high-voltage interlock and the male connector body.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a replaceable high-voltage connector to solve the problem that if the wiring is pulled during use, it will easily affect the stability of the high-voltage interlock and the connection of the male connector body.

[0009] The fixing component includes a support mechanism and a pressing mechanism installed at the lower end of the support mechanism. A docking mechanism is fixedly installed on both sides of the upper end of the pressing mechanism. The docking mechanism realizes the limiting installation of the pressing mechanism and the support mechanism.

The lower ends of the fixed block are respectively provided with top-entry grooves, and a through groove is provided in the middle of one side of the inner wall of the top-entry groove.

[0013] Furthermore, the pressing mechanism includes a central concave block and locking grooves on both sides of the upper end of the central concave block, and a handle is fixedly installed on one side of the lower end of the central concave block.

[0025] 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.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figure 1 As shown, a replaceable high-voltage connector includes a male connector body 1 and a female connector 2 disposed at one end of the male connector body 1. A high-voltage interlock 3 is installed in the middle slot cavity of the other end of the male connector body 1 for limiting insertion. A connecting wire 4 is disposed at one end of the high-voltage interlock 3. A sealing component 5 is fixedly installed at the other end of the male connector body 1 for limiting and fixing. The sealing component 5 is used to seal the slot at the other end of the male connector body 1 for dust prevention. A fixing component 6 is installed in the middle of one end of the sealing component 5. The fixing component 6 is used to improve the stability of the connecting wire 4.

[0028] like Figure 2 As shown, the fixing component 6 includes a support mechanism 61 and a pressing mechanism 62 installed at the lower end of the support mechanism 61. A docking mechanism 63 is fixedly installed on both sides of the upper end of the pressing mechanism 62. The docking mechanism 63 realizes the limiting installation of the pressing mechanism 62 and the support mechanism 61. The limiting installation of the support mechanism 61 and the pressing mechanism 62 realizes the clamping and fixing of one end of the connecting line 4. One side of the support mechanism 61 is fixedly installed on the side wall of the sealing component 5.

[0029] like Figures 3-5 As shown, the support mechanism 61 includes a fixed block 611 and concave grooves 612 formed on both sides of the lower end of the fixed block 611. The connecting line 4 is movably installed in the inner cavity of the concave groove 612. The lower ends of the fixed block 611 are respectively provided with top-entry grooves 613, and a through groove 614 is provided in the middle of one side of the inner wall of the top-entry groove 613.

[0030] like Figure 3 As shown, the support and pressing mechanism 62 includes a central concave block 621 and locking grooves 622 formed on both sides of the upper end of the central concave block 621. The locking grooves 622 are movably installed in the inner cavity of the concave groove 612 to limit and press the connecting line 4. A handle 623 is fixedly installed on one side of the lower end of the central concave block 621. The handle 623 is used to drive the central concave block 621 to move.

[0031] like Figure 3 As shown, the docking mechanism 63 includes an insertion block 631 and a pull spring 632 fixedly installed on both sides of the upper end of the insertion block 631. One end of the pull spring 632 is fixedly installed with one end of the inner cavity of the insertion groove 613. The insertion block 631 is movably installed in the inner cavity of the embedding groove 11 by the pull spring 632. A long connecting rod 633 is fixedly installed on one side of the upper end of the outer wall of the insertion block 631. One end of the long connecting rod 633 is fixedly installed on one side of the outer wall of the central concave block 621, and the other end of the long connecting rod 633 is slidably installed in the inner cavity of the through groove 614.

[0032] In this application, by inserting the replaceable high-voltage interlock 3 into the slot of the male connector body 1 (it should be noted that the upper end of the high-voltage interlock 3 is equipped with a locking block to cooperate with the locking block in the slot of the male connector body 1 for limiting and locking, thereby achieving the limiting installation of the high-voltage interlock 3), the connecting wire 4 is inserted into the middle of the inner cavity of the bonding plate 51, so that the sealing component 5 is limited and installed on the other end of the outer wall of the male connector body 1, thereby achieving the positional installation of the fixing component 6. When the connecting wire 4 is inserted into the middle of the inner cavity of the bonding plate 51, the connecting wire 4 will simultaneously pass into the inner cavity of the concave groove 612. At this time, if it is necessary to continuously move the connecting wire 4, the handle 623 needs to be pulled, so that the central concave block 621 drives the push-in block. 631 and the pull spring 632 move, and the pull spring 632 extends under the pulling action, thereby causing the locking groove 622 to exit from the inner cavity of the concave groove 612, thus loosening the connecting wire 4. After the sealing component 5 is installed in position, the handle 623 is loosened, causing the middle concave block 621 and the push block 631 to automatically retract under the elastic force of the pull spring 632, so that the locking groove 622 can be pushed back into the inner cavity of the concave groove 612, thereby limiting and fixing the connecting wire 4. With this setting, when the connecting wire 4 is pulled, since one end of the connecting wire 4 is directly fixed by the locking groove 622 and the concave groove 612, the stability of the connection between the high voltage interlock 3 and the male connector body 1 at the end of the connecting wire 4 is improved.

[0033] like Figure 2 and Figure 4 As shown, an embedding groove 11 is provided in the middle of both sides of the outer wall of the male connector body 1, and a circular groove 12 is provided in the middle of one side of the inner wall of the embedding groove 11.

[0034] like Figure 4 As shown, the sealing assembly 5 includes a bonding plate 51 and an embedding block 52 fixedly installed on both sides of one end of the bonding plate 51. The embedding block 52 is movably installed in the inner cavity of the embedding groove 11. The middle part of the outer wall of the embedding block 52 is respectively provided with a placement groove 53. An elastic element 54 is fixedly installed in the inner cavity of the placement groove 53. A semi-circular retaining ball 55 is fixedly installed at one end of the elastic element 54. The semi-circular retaining ball 55 is limited and movably installed in the inner cavity of the circular groove 12 under the elastic force of the elastic element 54, thereby fixing the position of the embedding block 52.

[0035] In this application, when installing the sealing component 5, the embedding blocks 52 fixedly installed on both sides of one end of the sealing component 5 are respectively inserted into the inner cavity of the embedding groove 11. When the semi-circular ball 55 encounters the groove opening of the embedding groove 11, it retracts into the inner cavity of the placement groove 53 under the elastic force of the elastic element 54. After the embedding block 52 is fully inserted, the semi-circular ball 55 will encounter the circular groove 12, thereby causing the elastic element 54 to extend and drive the semi-circular ball 55 to be locked into the circular groove 12 for limiting and fixing, thereby completing the fixed installation of the bonding plate 51 on one side of the male connector body 1.

[0036] The above are merely preferred embodiments of this application and are 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.
