Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description will be given, with reference to the accompanying drawings and preferred embodiments, of the structure of the curved tail clip and the connector including the same, which are suitable for accommodating a cable with a large bending radius according to the present invention, and the detailed implementation, structure, features and effects thereof.

Please refer to fig. 1-2, which are schematic structural views of a curved tail clip suitable for accommodating a cable with a large bending radius according to the present invention, the curved tail clip includes: body 1 and cable body 2 are pressed from both sides to curved tail, curved tail presss from both sides body 1 including head and the afterbody that is located the kink both ends, and this tail presss from both sides 1 head of body and is equipped with adapter sleeve 9, and the tail presss from both sides body 1 and realizes being connected and sealed with the connector plug through this adapter sleeve 9. In the embodiment of the present invention, an annular groove is disposed on the outside of the head of the tail clip body, and the rear end of the connecting sleeve 9 is provided with an outer sleeve matching with the annular groove on the outside of the head of the tail clip body and an inner sleeve extending into the head of the tail clip body, and the outer sleeve is disposed and stopped on the annular groove. And an annular groove matched with the connector plug spline shell is formed in the outer side of the front end of the connecting sleeve 9.
