Description

Technical Field

In addition, intermediate bare terminals are essential electronic components for connecting lines of industrial equipment and vehicles such as automobiles. The intermediate bare terminals are produced to facilitate the connection of two wires.

[0003] The current terminal tube cannot be disassembled after crimping two wires. During maintenance or inspection, the wires need to be cut to remove the terminal. After maintenance and inspection, the terminal needs to be crimped again. In addition, after cutting the wires, the wires may be insufficient, affecting installation. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present application provides a detachable intermediate bare terminal, which has the advantages that after the two wires are connected through a terminal tube, the two wires can be disassembled as needed, which is convenient for maintenance and inspection, and there is no need to cut the wires. After maintenance and inspection, there is no need to re-crimp the terminal blocks, and the connection can be directly restored. The connection is relatively stable, etc., which solves the problem that the current terminal tube cannot be disassembled after crimping the two wires, and the wires need to be cut to remove the terminal blocks during maintenance or inspection. The terminal blocks need to be re-crimped after maintenance and inspection, and the wire length may be insufficient after cutting the wires, affecting the installation.

[0005] In order to achieve the above-mentioned purpose that after the two wires are connected through the terminal tube, the two wires can be disassembled as needed, which is convenient for maintenance and inspection, and there is no need to cut the wires. After maintenance and inspection, there is no need to re-crimp the terminal blocks, and the connection can be directly restored, and the connection is relatively stable. The present application provides the following technical solutions: a detachable intermediate bare terminal, including a terminal tube, one end of the terminal tube is provided with an internal threaded tube, the inner wall in the middle of the internal threaded tube is threadedly connected with the outer surface in the middle of the external threaded tube, a wiring tube is provided on the inner wall in the middle of the external threaded tube, a wire is provided on the inner wall at one end of the wiring tube, and a terminal board is provided at the other end of the wiring tube, one end of the terminal board is in contact with one side of a limit plate, and the limit plate is provided on the inner wall in the middle of the terminal tube.

[0006] Through the above scheme, by arranging the internal threaded tube, the external threaded tube and the wiring tube, through the cooperation of the internal threaded tube and the external threaded tube, the wiring tube can separate the corresponding wire from one end of the terminal tube, so that after the two wires are connected through the terminal tube, the two wires can be disassembled as needed, which is convenient for maintenance and inspection, and there is no need to cut the wires.

The provision of the anti-slip strip makes rotating the connecting cover more labor-saving and avoids slipping.

[0009] Furthermore, an annular limiting groove is provided on the outer surface of the middle part of the wiring tube, a limiting ring is rotatably arranged on the inner wall of the limiting groove, and the outer circumferential surface of the limiting ring is arranged on the inner wall of the middle part of the externally threaded tube.

[0010] Through the above solution, the stability of the wiring tube when rotating in the external threaded tube can be improved by cooperating with the limiting groove through the limiting ring.

[0011] Furthermore, a limit strip is provided at one end of the inner wall in the middle of the terminal tube, and two limit strips form a group.

[0013] Furthermore, the limit strips are respectively arranged at both ends of the inner wall of the middle part of the terminal tube, and the limit strips at both ends of the inner wall of the terminal tube are arranged in two groups, and the two groups of limit strips at one end of the inner wall of the terminal tube are arranged symmetrically up and down.

[0014] Through the above scheme, the upper and lower limit strips at one end of the inner wall of the terminal tube can cooperate with the two limit rods on both sides of the outer surface of one end of the wiring tube to improve the stability of the wiring tube when moving.

[0015] Furthermore, there are two internally threaded tubes, which are respectively arranged at both ends of the terminal tube, and the inner walls in the middle of the two internally threaded tubes are respectively threadedly connected with the outer surfaces in the middle of the two externally threaded tubes.

[0016] According to the above scheme, the two wiring tubes and the wires can be removed from the terminal tubes respectively by using two external threaded tubes to cooperate with two internal threaded tubes.

[0018] Through the above scheme, the conductive spring sheet can be arranged in cooperation with the conductive plate and the limit plate to transmit signals to the terminal plate, thereby avoiding a virtual connection between the terminal plate and the limit plate resulting in the terminal tube being unable to conduct normally.

[0019] Furthermore, two conductive plates are arranged on one side of the limiting plate, two conductive springs are arranged on one side of the two conductive plates respectively, and the two conductive plates and the two conductive springs on the same side of the limiting plate are symmetrically arranged on both sides of the corresponding terminal plate.

[0020] Through the above solution, the efficiency of conduction can be improved by cooperating with the two conductive plates through the two conductive springs on both sides of the terminal board.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
