Description

Technical Field

[0001] The utility model relates to the technical field of electrical accessories, and more specifically, to a cable connector. Background Art

[0002] The traditional cable joint consists of a conductive sheet and a metal connecting tube welded thereon. The cable end with the insulation layer removed is inserted into the metal connecting tube, and then the metal connecting tube is riveted to achieve a tight connection between the metal connecting tube and the cable end due to local deformation. However, since the inner tube wall of the metal connecting tube is mostly smooth and flat, it still does not have a strong gripping force after deformation, resulting in limited connection strength and poor overall effect. Accordingly, the utility model proposes a cable joint. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned deficiencies in the prior art and to provide a cable connector which has the characteristics of high connection strength and safe and reliable use.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows: the utility model involves a cable connector, including a conductive sheet, one end of which is welded with a metal connecting tube, the tube wall of the metal connecting tube is provided with at least two process holes, and the process hole is provided with a bite sheet, one end of the bite sheet is connected to the hole wall of the process hole, and the other end extends into the interior of the metal connecting tube and is provided with bite teeth.

[0005] The utility model is further configured such that: the length extension direction of the bite piece is perpendicular to the axial direction of the metal connecting pipe.

[0006] The utility model is further configured as follows: a plurality of first grooves extending radially left and right and arranged at intervals along the axial direction are formed at one end of the metal connecting tube not connected to the conductive sheet, and the first grooves are arranged on the metal connecting tube in a bilaterally symmetrical manner;

[0007] The end of the metal connecting tube not connected to the conductive sheet is provided with a plurality of second grooves extending radially forward and backward and arranged at intervals in the axial direction. The second grooves are arranged symmetrically in the front and back of the metal connecting tube, and the second grooves are arranged alternately with the first grooves.

[0008] The utility model is further configured as follows: the process hole is opened at one end of the metal connecting tube close to the conductive sheet.

[0009] The utility model is further configured as follows: the spacing between two adjacent first cutting grooves is equal; the spacing between two adjacent second cutting grooves is equal.

[0010] The utility model is further configured as follows: the number of the process holes is not less than three; and the interval angles between two adjacent process holes are equal.

[0011] The utility model is further configured as follows: a connecting hole is provided on the conductive sheet.

[0012] In summary, the utility model has the following beneficial effects:

[0013] 1. When the bite piece added in the process hole undergoes local deformation along with the metal connecting tube, the bite teeth on the bite piece will penetrate into the cable end inserted in the metal connecting tube along with the deformation, making the connection tight and reliable.

[0014] 2. The first and second grooves added at the end of the metal connecting tube in an alternating arrangement make the end of the metal connecting tube elastic and can be freely bent in the up, down, left and right directions, so that the wire tube connection is transformed from a rigid connection to a flexible connection, indirectly protecting the connecting cable.
