Description

Technical Field

[0001] The utility model relates to the technical field of sealing plugs, in particular to a high-voltage charging harness sealing plug. Background Art

[0002] High-voltage charging harness sealing plugs are used to seal high-voltage charging harnesses. They prevent external contaminants such as water, dust, and dirt from entering the device through the charging harness interface or through-holes, ensuring the reliability and tightness of the electrical connection. Existing high-voltage charging harness sealing plugs have the following main problems: they lack a branching function and cannot effectively organize and manage multiple harnesses. In particular, when multiple harnesses need to pass through the same location, the harnesses may pile up, resulting in uneven arrangement, easy entanglement, and wear. These plugs are not suitable for complex harness systems. Improvements and optimizations are being made to address these issues. Utility Model Content

[0017] like Figure 1-5As shown, the high-voltage charging wiring harness sealing plug involved in the present invention includes a sealing plug body 1 and a branching pad 2. The sealing plug body 1 is provided with a sealing plug front boss 4, a sealing plug compression part 5 and a sealing plug rear connecting part 6 in sequence from front to back. A sealing plug wiring hole 7 is provided in the sealing plug body 1. The outer wall of the sealing plug compression part 5 is provided with a sealing plug outer compression groove 8. The inner wall of the sealing plug compression part 5 is provided with a sealing plug inner compression groove 9 at the sealing plug wiring hole 7. The sealing plug front boss 4 is provided with a front boss docking groove 10 which is communicated with the sealing plug wiring hole 7 and is used for inserting the branching pad 2. The sealing plug front boss 4 is provided with a sealing plug for inserting the branching pad at the front boss docking groove 10. 2 is connected to the front card slot 11 of the sealing plug, and the branching pad 2 is provided with at least two branching holes 12 arranged at intervals around a circular arc. A detachable and replaceable branching pad 2 is added, the wiring harness is arranged neatly, and installation and disassembly are more convenient, which reduces the friction and collision between multiple wiring harnesses, greatly extends the service life of the wiring harness, and has higher adaptability; the rear connecting part 6 of the sealing plug is provided with a rear connecting part positioning groove 13 which is communicated with the sealing plug wiring hole 7 and docked with the wiring harness rear cover, and the inner wall of the rear connecting part positioning groove 13 is provided with a rear connecting part clamping convex edge 14 which is clamped with the wiring harness rear cover. The sealing plug and the wiring harness rear cover are tightly and firmly clamped to form a whole. The sealing plug does not need to be crimped with the terminal before installation, which reduces the installation steps and is more convenient to operate.

[0018] The end surface of the front boss 4 of the sealing plug is provided with sealing plug anti-rotation notches 16 at intervals around a circular arc. There are two sealing plug anti-rotation notches 16, which allow the sealing plug to always maintain the correct position and reduce misoperation caused by unstable installation.

[0019] The rear end surface of the sealing plug rear connecting part 6 is provided with sealing plug rear positioning posts 17 at intervals around a circular arc. The sealing plug rear positioning posts 17 are arranged through the wiring harness rear cover. On the one hand, they serve to strengthen the tightness of the connection between the sealing plug and the wiring harness rear cover. On the other hand, the usage status of the sealing plug can be judged by observing the exposed length of the sealing plug rear positioning posts 17.

[0020] The outer diameter of the sealing plug front boss 4 is the same as the outer diameter of the sealing plug rear connecting portion 6 , and the outer diameter of the sealing plug compression portion 5 is larger than the outer diameter of the sealing plug front boss 4 .

[0021] The cross sections of the outer compression groove 8 of the sealing plug and the inner compression groove 9 of the sealing plug are both wedge-shaped structures. The wedge-shaped structure design not only increases the compression effect of the sealing material, but also distributes the pressure more evenly, thereby improving the sealing performance.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
