Examples

Referring to fig. 1 and 2, the present application provides a connection terminal, which includes a base 1 having a wire hole 11 and a threaded hole 12, a cutting element and a threaded element 3 are disposed in the threaded hole 12, the cutting element is in sliding fit with the threaded hole 12, and the threaded element 3 is in threaded fit with the threaded hole 12. When the screw member 3 is screwed in, the cutting member can be pushed to slide towards the wire hole 11, the outer skin of the electric wire in the wire hole 11 is cut, and the cutting member is made of a conductive material.

Referring to fig. 1 and 2, specifically, there are two line holes 11, and the two line holes 11 are parallel to each other and both extend through two sides of the seat body 1 along a horizontal direction. Threaded hole 12 sets up at the top surface of pedestal 1, and threaded hole 12's quantity is totally four, and four threaded holes 12 all set up along vertical direction, and two threaded holes 12 are corresponding to a line hole 11 to with the 11 intercommunications in line hole that correspond, two threaded holes 12 are located the both ends in line hole 11 respectively. During the use, insert a wire in line hole 11, and another electric wire is then twined on screw 3, owing to set up two screw holes 12, the screw 3 that the winding has the electric wire can be installed in arbitrary one screw hole 12 department, avoids leading to binding post unable the use because screw hole 12 damages.

Referring to fig. 1 and 2, two guide grooves 13 are formed in the side wall of the threaded hole 12 along the vertical direction, the two guide grooves 13 are respectively located at two sides of the axis of the threaded hole 12, one end of each guide groove 13 is communicated with the wire hole 11, and the other end of each guide groove 13 penetrates through the top surface of the seat body 1. The cutter comprises a circular plate body 2, and the plate body 2 is embedded between two guide grooves 13 and slides relative to the guide grooves 13 along the axial direction of the guide grooves 13.

Referring to fig. 1 and 2, a first groove 21 is formed at an end of the plate body 2 opposite to the screw member 3, and an edge between a groove wall of the first groove 21 and the plate body 2 is processed into a sharp shape to form a blade 22. When the plate body 2 is in contact with the wire in the wire hole 11, the wire may be caught in the first groove 21 so that the blade portion 22 cuts the outer skin of the wire, thereby preventing the wire in the wire hole 11 from slipping off when in contact with the blade portion 22.

Referring to fig. 1 and 2, the following describes a specific structure of the screw member 3 as follows:

the screw member 3 includes a stud 31 and a block 32, the stud 31 is detachably connected with the block 32, a thread groove (not shown) is formed on the bottom surface of the block 32, and one end of the stud 31 is screwed into the thread groove, so that the stud 31 is detachably connected with the block 32. The user can grip the block 32 and conveniently turn the screw member 3.
