Detailed Description

The present application is described in further detail below with reference to the accompanying drawings.

The embodiment of the application discloses a bare terminal.

Referring to fig. 1 and 2, a bare terminal for connecting strip includes a joint end 1 and a terminal end 2 which are integrally formed, and a strip 3. One side integrated into one piece that terminal 2 kept away from connector end 1 is provided with a plurality of in the material area 3 in the quantity of terminal 2 on the material area 3, and the terminal 2 is evenly spaced in proper order along the length direction of material area 3 and arranges. The shape of the connector end 1 is one of fork shape, round shape, needle shape, sheet shape, lock catch shape and hook shape. The present embodiment is illustrated with a circular shape.

As shown in fig. 2 and 3, the inner side wall of the terminal 2 is provided with a threaded surface 20, and the threaded surface 20 is used for pressing the surface of the electric wire against each other. The thread surface 20 is formed with a plurality of threads, and the length of the threads extends in a direction perpendicular to the direction in which the electric wire is separated from the terminal 2. When the wire is pressed by both sides of the terminal 2, the screw surface 20 on the inner side wall of the terminal 2 is pressed against the wire surface and bites against the wire surface.

As shown in fig. 2 and 3, the inner side wall of the bottom side of the terminal 2 away from the terminal end 1 is formed with a first chamfer 21, and the first chamfer 21 is used for guiding the electric wire to be smoothly inserted into the terminal 2. Thereby ensuring a more stable and firm compression of the wire in the terminal 2 while also improving the overall conductivity. The second chamfer 22 is formed on the outer side wall of the wiring terminal 2, which is away from the first chamfer 21, and the smooth bending of the bottom edge of the wiring terminal 2 can be ensured through the second chamfer 22, so that the bottom edge of the wiring terminal 2 can be smoothly bent and the electric wire can be wrapped, and the fixing effect on the electric wire can be further improved.
