The following section explains in detail the technical solutions of the present application and how these solutions solve the technical problems mentioned above, using specific embodiments. The following specific embodiments can be combined, and the same or similar concepts or methods may not be repeated in some embodiments. The following section explains embodiments of the present application with reference to the drawings. An embodiment of the present application provides an electrical connector. With reference to Figures 1 and 2, the electrical connector comprises: a socket body 100; several first plug-in elements 200, each arranged in the socket body 100; a plug body 300, which is latched to the socket body 100; several second plug-in elements 400, which are arranged in the plug body 300, the second plug-in elements 400 being inserted into the corresponding first plug-in elements 200; several fuse terminals 500, which are arranged in the plug body 300, each with a fuse 510 detachably connected to the fuse terminals 500, one end of each fuse 510 being connected to the respective first plug-in element 200. Using the example of the connection of a high-voltage direct current line in the present application, the fuse terminals 500 are connected to the positive pole in the circuit and the second plug-in elements 400 are connected to the negative pole in the circuit. For example, the first plug-in elements 200 are female terminals, the second plug-in elements 400 are male terminals, and the second plug-in elements 400 are inserted into the corresponding first plug-in elements 200 to establish an electrical connection between the conductors at both ends of the plug body 300 and the socket body 100. Furthermore, the first plug-in elements 200 can be configured as male terminals and the second plug-in elements as female terminals, a point which will not be repeated here. Based on the requirements of conventional high-voltage and low-current connections, the high-voltage circuit's overcurrent protection function is integrated to improve overcurrent protection capability. Furthermore, the fuse 510 is located within the connector body 300, eliminating the need for a high-voltage distribution box and high-voltage adapter circuit. This allows for easier replacement of the fuse 510 at the cable harness end and avoids difficulties when replacing the fuse 510, even when the connector body 100 is installed in a confined space. This simplifies the maintenance process. Furthermore, under certain circumstances, if nearby components are damaged during the fuse 510 melting process, the plug body, including the fuse 510, can be replaced as a whole without repairing the socket body. This eliminates complex procedures such as removing the device front panel to replace the socket body while it is installed on the device. Examples include the socket body 100 and the plug body 300, which are plastic parts designed to improve protection and reduce the possibility of leakage. In one possible embodiment, the fuse 510 comprises a plug-in section 511 and a fuse section 512, wherein the plug-in section 511 is arranged at the end of the fuse section 512, wherein the fuse section 512 is plugged into the respective fuse terminal 500, and the plug-in section 511 is connected to the respective first plug-in element 200. In other embodiments, the electrical connector can also be used for cable connections or connections of electrical devices at common voltages. Furthermore, it is also possible to improve the properties of the connection circuit by removing the second plug-in elements and replacing them with several 500-pin fuse connections. In particular, the plug section 511 is a conductor, and the fuse section 512 is an existing fuse 510 with a fuse wire inside, both ends of which are conductors. The plug section 511 is attached to one end of the fuse section 512, the plug section 511 being used for insertion into the first plug section 200, and one end of the fuse section 512, which is away from the plug section 511, is inserted into the respective fuse terminal 500 so that the conductors at both ends of the socket body and the plug body are connected. In one possible embodiment, the electrical connector further comprises a retaining ring 600, which is arranged in the connector body 300 and is detachably connected to the connector body 300, wherein the retaining ring 600 extends through the plugging section 511 and abuts the locking section 512 in order to secure the locking section 512.

It is detachably connected to the connector body 300 when placed on the connector section 511 and abutting the locking section 512, thus securing the fuse 510. Furthermore, the fuse 510 can be removed simply by removing the retaining ring, making fuse replacement quick and easy. This improves maintenance efficiency and eliminates the need for a complete connector replacement, thereby reducing maintenance costs. In one possible embodiment, with reference to Fig. 1 and Fig. 3, a locking projection 610 is arranged on one of the retaining ring 600 and the connector body, while a locking slot 310 is arranged on the other of the retaining ring 600 and the connector body, wherein the locking projection 610 is engaged in the locking slot 310. In one embodiment of the present application, the locking projection 610 is arranged, for example, on the retaining ring 600. In other embodiments, the locking projection 610 can also be arranged on the connector body 300. Furthermore, the retaining ring 600 comprises a body section 620 and a retaining section 630, wherein the locking projection 610 is arranged on an outer side wall of the body section 620, wherein the retaining section 630 is arranged at the end of the body section 620, and the retaining section 630 abuts against the locking section 512, wherein a through-hole 631 is formed in the retaining section 630 through which the plug-in section 511 extends into the body section 620. A gap is provided between the body section 620 and the plug-in section 511 to allow the insertion of the first plug-in element 200 into the body section 620. Body section 620 and retaining section 630 are formed as a single piece. Retaining section 630 is located at the end of body section 620 and is connected to the inner wall of body section 620.

The locking projection 610 is located on the outer wall of body section 620. The locking projection 610 and body section 620 are formed as a single piece and are made of plastic. When the detent projection 610 is engaged with the detent slot 310, the retaining section 630 abuts the locking section 512 to secure the lock 510.To replace the fuse 510, the locking tab 610 can simply be moved slightly back and forth to release it from the locking slot 310, so that the retaining ring 600 can be removed and replaced together with the fuse 510, making the operation quick and easy. In one possible embodiment, the fuse terminal 500 comprises a ring section 520 and a connecting section 530, wherein the ring section 520 is arranged at the end of the connecting section 520, and the fuse section 512 is inserted into the ring section 520, the connecting section 530 serving to connect to an external conductor. The ring section 520 and the connecting section 530 are conductors. The ring section 520 and the connecting section 530 are formed as a single piece. The fuse section 512 is inserted into the ring section 520 to connect the fuse 510 to the fuse terminal 500, and the connecting section 530 serves to connect to the conductor at the end of the connector body. In one possible embodiment, with reference to Fig. 1 and Fig. 3, a slot is provided on a side wall of the ring section 520 to increase the diameter of the ring section 520, wherein the inner diameter of the ring section 520 corresponds to the diameter of the end of the locking section 512, so that the ring section 520 fits snugly against the locking section 512. The inner diameter of the ring section 520 is equal to or smaller than the diameter of the end of the locking section 512. When the locking section 512 is inserted into the ring section 520, the locking section 512 spreads the ring section 520 through the slot so that the ring section 520 fits tightly against the locking section 512 to improve the interception effect and prevent damage from an inadequate connection. In addition, several through slots are evenly distributed on the side wall of the ring section 520, so that the ring section 520 is cage-shaped, which improves the deformability of the ring section 520, so that the ring section 520 and the locking section 512 fit better. In one possible embodiment, several shielding inner rings 700 are arranged in the connector body 300, which serve to be placed on the conductors of the cable harness. Furthermore, several outer shielding rings 800 are arranged in the connector body 300, which are placed on the corresponding inner shielding rings 700 in order to clamp a shielding layer of the cable harness between the outer shielding ring 800 and the inner shielding ring 700.
