Embodiment 2

[0070]Embodiment 2 of the electrical connection terminal in the present invention: the difference from the above embodiment is that in this embodiment, the wire enters and exits the housing along the left and right directions, and the crimping body is guided and assembled on the housing along the up and down direction, and the crimping body When going down, the wire can be pressed to the connecting conductor, and when the wire pressing body is going up, the wire can be released to make the wire withdraw from the housing. One of the casing and the crimping body is provided with a sliding groove, and the other is provided with a slider, and the sliding groove cooperates with the guide of the sliding block so that the crimping body can move and be assembled on the housing. The lock tongue is arranged in the housing along the left and right directions, and a lock tongue elastic member is still arranged in the housing to provide an active force. The side of the crimping body facing...

Embodiment 3

[0071] Embodiment 3 of the electrical connection terminal in the present invention: the difference from the above embodiments is that in this embodiment, the conductive part used to electrically connect with the wire entering the housing is arranged on the crimping body, when the crimping body itself faces When the wire moves to compress the wire, the electrical connection between the conductive part on the wire pressing body and the wire is also realized, and the conductive part on the wire pressing body can be electrically connected with other conductors.

[0072] Embodiment 4 of the electrical connection terminal in the present invention: the difference from the above-mentioned embodiments is that in this embodiment, the locking part that locks and cooperates with the crimping body is fixedly arranged on the housing, and the crimping body can be rotated and set It can be moved in a straight line and set in the housing. The locking part is a locking tooth arranged along the ...

Embodiment 5

[0073] Embodiment 5 of the electrical connection terminal in the present invention: the difference from the above embodiments is that the crimping body in this embodiment includes a cylinder, and the cylinder is rotatably assembled on the housing. On the surface, a lock hole or a lock groove adapted to the lock tongue is provided. The hole edge of the lock hole can stop and cooperate with the lock tongue to limit the position of the crimping body. The lock hole can be a square hole, and the hole edge of the square hole can stop and cooperate with the dead bolt during the rotation stroke of the cylinder, and is not limited to the scheme of setting a plurality of ribs and using the ribs to form the lock groove.

[0074] Embodiment 6 of the electrical connection terminal in the present invention: the difference from the above embodiments is that in this embodiment, the operating arm is fixedly arranged on the crimping body, and the position of the operating arm relative to the cr...

Abstract

The invention relates to an electric wiring terminal which can solve the problems of easy failure of crimping and poor stability caused by compensating the distance between wires with different sizesand a wire pressing body only by means of the elastic deformation of an elastic sheet in the prior art. The electric wiring terminal comprises a shell in which a crimping cavity for a wire to enter isformed; and the wire pressing body which is rotationally or movably assembled on the shell. The shell is provided with a locking part which is matched with the wire pressing body in a locking manner,and the wire pressing body can be locked with the locking part at multiple positions in the rotating or moving stroke of the wire pressing body so as to press wires with different wire diameters to realize the conductive connection. The wire pressing body is provided with a plurality of positions matched with the locking parts, an operator selects different positions to adapt to the wires of different sizes, the position where the wire pressing body is located corresponds to the radial size of the wires, and the wire pressing body can be matched with the locking part on the shell at each position to press the wires.

Description

technical field [0001] The invention relates to an electric terminal. Background technique [0002] In the construction site of communication equipment or electrical equipment, electric terminals are often used. The traditional electric terminal is provided with a body with a crimping hole, and a crimping screw is screwed on the body, and the wire is fixed by the crimping screw. The crimping screw crimping method has problems such as inconvenient wire making, inaccurate pressing force of the manually operated crimping screw on the wire, poor reliability, and low efficiency. [0003] With the development of technology, some electrical terminals that can be quickly crimped by handle operation have appeared in the market, such as an electrical terminal disclosed in the patent document with the application publication number CN110176674A and the application publication date of 2019.08.27. The electrical connection terminal includes a housing, on which a threading hole for the w...
