Description

Technical Field

[0001] The utility model relates to an improvement of a charging gun structure, in particular to a charging gun wiring harness fixing device. Background Art

[0002] The charging gun is an electrical device used to dock with a charging base. Power lines, signal lines and even pipelines are centrally arranged on the charging gun. Therefore, the outer diameter of the wiring harness connected to the rear of the charging gun is large. If it is not fully fixed to the charging gun structure, there will be problems of detachment and breakage. Therefore, the structure needs to be improved to improve the fixing reliability of the wiring harness. Utility Model Content

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and to provide a charging gun wiring harness fixing device.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is as follows: a wire harness fixing device is disposed within the handle of the charging gun, a fixing groove is formed within the handle, the wire harness fixing device is clamped around the outside of the wire harness and embedded in the fixing groove, the wire harness fixing device is annular in structure as a whole, its inner diameter is tightly matched with the outer diameter of the wire harness, the wire harness fixing device is provided with a fixing hole, a fixing piece is inserted through the fixing hole and the wire harness fixing device is fixed in the fixing groove. The wire harness is restrained by the fixing device and is integrally embedded in the inner side of the handle of the charging gun, which can achieve smooth passage of the wire harness and reduce bending of the wire harness. Because the fixing realizes an integrally connected structure, it is reliably fixed to the charging gun as a whole, avoiding bending of the lines and pipes and improving structural reliability.

[0005] Furthermore, the harness securing device comprises a restraining structure formed by the engagement of two semi-annular restraining bodies. The mating surfaces of the two restraining bodies are formed with opposing engagement bodies and engagement grooves, and the two restraining bodies are connected by the engagement bodies and engagement grooves. The use of two semi-annular structures to secure the harness facilitates securing the harness from both sides. The internal restraining space is designed to correspond to the harness's outer diameter. During engagement, the connection between the engagement bodies and engagement grooves allows for rapid alignment and prevents slippage and loosening.

[0006] Furthermore, the mating body and mating groove are formed as a conical body and a conical groove, respectively, wherein the depth of the conical groove is greater than the length of the conical body. The conical body and the conical groove have a good positioning function, are not easy to slip after mating, and have high installation efficiency. The greater depth of the conical groove allows the conical body to be fully inserted into place, which can serve as an intuitive basis for whether the mating is complete.

[0007] Furthermore, the surface of the inner ring of the wiring harness fixture is formed with several compression bodies, which are arranged as a protrusion toward the center based on the surface of the inner ring. The compression bodies are arranged in multiple rows in the axial direction of the wiring harness fixture and are radially arranged in the mid-section of the semi-circular arc. The compression bodies function to imprint and fix the surface of the wiring harness, creating resistance in both the axial and radial directions to prevent the wiring harness from shifting. The compression bodies are mainly concentrated in the mid-section of the semi-circular arc, mainly designed to respond to the pressure of the engagement, and provide a better clamping effect.

[0008] Furthermore, the restraint body has a through-hole formed in its physical structure, parallel to the inner hole of the harness fixture. Each restraint body has at least one such hole. The holes are used with screws to secure the harness fixture. Each restraint body has a fixing hole, achieving a more effective installation and fixation.

[0009] Furthermore, a raised element is provided at the bottom of the fixing groove. This element is formed by thickening the bottom surface of the fixing groove. The side edges of the raised element are separated from the side edges of the fixing groove. The raised element is formed with a base surface, and the end surface of the wiring harness fixture is aligned with the base surface. The raised element at the bottom of the fixing groove serves as a more reliable connection foundation structure. Its flat support surface provides good adhesion to the wiring harness fixture and acts as a thickening and strengthening structure, achieving better structural fixation.

[0010] Compared with the existing technology, the present invention has the following advantages and effects: the present design is a restraining device for fixing the wiring harness of the charging gun, which can realize the smooth passage and installation of the wiring harness, has a protective effect on the wiring harness, improves the overall fixation reliability of the wiring harness and the charging gun, and improves the safety of electricity use.
