[0028] The utility model discloses a connector tail attachment in a first aspect, which mainly comprises a tail attachment tube and a tail attachment cover.

[0029] like Figure 2 As shown, the tail attachment tube includes a tail attachment tube body 11 and a tail attachment plate 12. The tail attachment tube body 11 is cylindrical and has openings at both ends. The tail attachment plate 12 is arranged at one end of the tail attachment tube body. The tail attachment tube body 11 and the tail attachment plate 12 are an integral structure or detachably connected. The other end of the tail attachment tube body 11 is provided with a first connection structure 13 for detachably connecting with a socket. The first connection structure can be a screw hole or a thread, that is, the connection between the tail attachment tube body 11 and the socket can be bolted or threaded.

[0030] The tail attachment cover 2 is disposed on one side of the tail attachment plate 12 and is detachably connected to the tail attachment plate 12 via a second connection structure 21 .

[0031] At least one of the tail-attached cover and the tail-attached plate is provided with at least one step structure on one adjacent side thereof, and the step structure is provided so that a wire outlet hole 3 is formed between the tail-attached cover, the tail-attached plate and the step structure.

[0032] In order not to affect the lead wire, the second connection structure between the tail cover and the tail plate is arranged at the step structure. The second connection structure can be bolted.

[0033] With the above structure, a step structure is provided on the tail tube and / or the tail cover to form a wire outlet hole 3. The tail plate can achieve cable pressing while closing the end of the tail tube. According to the requirements of the number and direction of the wiring, a corresponding number of step structures can be provided at the corresponding position.

[0034] The above structure can not only realize the output of cables in multiple directions, but also facilitate the setting of cables without being restricted by the size of connectors, and has a simple and lightweight structure and is convenient for connecting shielding.

[0035] Example 1: The step structure may be provided only on the tail cover or the tail plate, and the number of the step structures may be 1, 2, 3, 4, 5 or even more. When the step structure is provided only on the tail cover, the thickness of the step structures on the tail cover is equal. When the step structure is provided only on the tail plate, the thickness of the step structures on the tail plate is equal.

[0036] Example 2: Figure 1 , 5 As shown, the step structures can be provided on the tail cover or the tail plate at the same time. The number of the step structures on the tail cover or the tail plate is equal and the positions are corresponding.

[0037] Based on any structure of Example 1 and Example 2, take the example of 4-direction outgoing lines. Figure 3 , 4 As shown, four step structures are arranged on the tail cover and / or the tail plate. Screw holes are arranged on the step structure to install the second connection structure, i.e., bolts. The tail tube and the tail cover are made of aluminum alloy, and the outer coating is chemical nickel plating, which is conductive. The tail cover, the tail plate, and the two adjacent step structures respectively form closed outlet holes 3 in four directions. The tail cover is circular. The side wall of the step structure is smooth, so that the outlet hole 3 formed is smooth to prevent the risk of cutting the cable.

[0038] Based on any one of the above-mentioned connector tail attachment structures, the second aspect of the utility model discloses a connector. Figure 1 As shown, the connector includes a socket 4, a collar 5 arranged on the socket 4 and a connector tail detachably connected to the socket 4, and the connector tail is the connector tail described in the first aspect and any one of its possibilities.

[0039] Using the above structure, one wiring method is:

[0040] When wiring, first weld the corresponding wires at each point of the socket 4, put on a suitable shielding sleeve outside the wire, then put on the wire protection nylon, loosen the shield inside the outlet hole, wrap it with conductive tape, and when the 4 bolts press the tail cover, the shield and nylon can be pressed, and the corresponding winding can be used to achieve the clamping effect to prevent loosening. The size and orientation of the 4 openings can be adjusted according to the actual thickness and orientation of each outlet wire.

[0041] With the above structure, the cables led out of the connector are placed on one side of the tail cover 2. In the application scenario where heavy objects are hoisted, the hoisting line of the heavy objects can be prevented from hitting the cables, thereby protecting the connector cables.

[0042] The above structure can realize the routing function in multiple directions, and the shield can be connected in each direction without damaging the outer rubber of the core wire. It is easy to operate, the shield wiring and the outer sheath are clamped reliably, and the cable assembly can be protected on one side to prevent heavy objects from damaging the multi-directional outgoing lines during the vertical hanging process.

[0043] The above structure is small in size and can be used in a narrow space. At the same time, it can clamp the shielding and cable sheath of each strand, so that the shielding can be conductive and the cable can be prevented from loosening. The material is coated with aluminum alloy, the overall structure is light and compact, the electrical operation process is simple and operable, and it can avoid damage to the cable by hanging heavy objects on one side.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
