[0029] [First Embodiment]

[0030] As Figures 1-6 shown, a wire harness connector provided in the first embodiment of the present utility model includes a housing 1. One end of a cable 2 extends into the interior of the housing 1 and is connected to a terminal 3. A sleeve 4 is also sleeved on the outer peripheries of the housing 1 and the cable 2. In this embodiment, the sleeve 4 is fixed to the outer peripheries of the housing 1 and the cable 2 by a crimping method, and one end of the sleeve 4 axially abuts against the housing 1. Preferably, in this embodiment, the cross-section of the crimped sleeve 4 is in a regular hexagon shape, which is beautiful in appearance and convenient for manufacturing and forming. At the same time, the outer edge of the hexagon is also beneficial to the stability of placing on the tabletop, avoiding unexpected rolling and other situations that may be caused by a circular outer edge.

[0031] The improvement of this embodiment compared with the prior art lies in that: the housing 1 includes an outer housing 11 and an inner housing 12 located inside the outer housing 11. The outer housing 11 and the inner housing 12 are fixedly connected by snap - fitting. By setting the housing as an inner housing and an outer housing that are snap - fitted to each other, compared with the integral fixed housing structure in the prior art, it saves consumables, reduces costs, and at the same time facilitates the loading and unloading process of the connector. The operation is simple and time - consuming less, which is beneficial to the subsequent progress of maintenance and other work.

[0032] As Figure 5 shown, the outer housing 11 includes an outer housing front part 111 and an outer housing rear part 112 that are connected to each other. The outer diameter of the outer housing rear part 112 is larger than the outer diameter of the outer housing front part 111. Preferably, the cross - section of the outer housing rear part 112 is set as a regular hexagon. Similarly, setting the cross - section of the outer housing rear part 112 as a regular hexagon not only maintains the aesthetic appearance but also facilitates manufacturing and forming. At the same time, the hexagonal outer edge is also beneficial to the stability of placing on the tabletop, avoiding unexpected rolling and other situations that may be caused by a circular outer edge.

[0033] As Figure 6 shown, the inner housing 12 in this embodiment includes an inner housing front part 121, an inner housing middle part 122, and an inner housing rear part 123 that are connected in sequence. The outer diameter of the inner housing middle part 122 is larger than the outer diameter of the inner housing front part 121, and the outer diameter of the inner housing front part 121 is larger than the outer diameter of the inner housing rear part 123. The outer diameter of the inner housing middle part 122 is set to be the largest to facilitate the axial abutment with the outer housing rear part 112 on the front side and the sleeve 4 on the rear side.

[0034] Preferably, as Figure 4 and Figure 6 shown, the inside of the inner housing front part 121 is filled with an isolation body 5. The isolation body 5 is located radially between the outer periphery of the terminal 3 and the inner wall of the inner housing front part 121 to position, support, and protect the internal terminal 3. The isolation body 5 in this embodiment is preferably made of an insulating material such as plastic to improve the safety of plug - in use while realizing the functions of positioning, support, and protection.

[0035] Furthermore, as Figure 6 shown, a shielding net is provided on the outer edge of the inner housing rear part 123 to ensure the signal transmission stability of the internal cable 2 and the terminal 3.

[0036] As Figures 4-6As shown in the figure, a positioning ring 113 is provided at the rear end of the rear part 112 of the outer shell in this embodiment, protruding towards the radially inner side. Correspondingly, a positioning groove 124 is provided at the outer edge of the connection position between the front part 121 and the middle part 122 of the inner shell. The positioning ring 113 extends into the inside of the positioning groove 124 and is in positioning cooperation with it. The outer shell is fixedly installed on the outer periphery of the inner shell by the positioning ring extending into the inside of the positioning groove and being in positioning cooperation with it. During disassembly, the positioning ring can be taken out from the inside of the positioning groove to complete the disassembly process, thus facilitating the loading and unloading process of the joint. The operation is simple and time-consuming less, which is beneficial to the subsequent progress of maintenance and other work.

[0037] As a further preference, the axial dimension of the positioning ring 113 in this embodiment is smaller than the axial dimension of the positioning groove 124 to further improve the convenience of loading and unloading.

[0038] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
