Referring to fig. 1 to 3 of the drawings, a wire frame assembly according to a preferred embodiment of the present invention will be explained in the following description, which includes a wire frame 10, a screw 20, a pad 30, and a pin 40.

The wire-pressing frame 10 includes a lower end wall 11, an upper end wall 12, and two side walls 13 connected to the lower end wall 11 and the upper end wall 12 and disposed opposite to each other. The lower end wall 11 is provided with a wiring hole (not shown) for a lead to pass through, the upper end wall 12 is provided with a threaded hole (not shown) for the screw rod 20 to move up and down, the outer surface of the screw rod 20 is provided with threads, and the pressing end of the screw rod 20 extends into the wire pressing frame 10 through the threaded hole.

The pad 30 is provided with a through hole 31, and the pin rod 41 of the pin 40 passes through the through hole 31 and is pressed into the press-fixing end of the screw rod 20. The head 42 of the pin 40 has a diameter greater than the diameter of the through hole 31 so that the pad 30 is captured between the fastening end of the screw 20 and the head 42 of the pin 40.

It should be mentioned that the screwing end of the screw 20 is tubular, an inner hexagonal groove 22 is arranged in the screwing end, and a linear groove 21 is formed on the end surface of the side wall 13 of the screwing end of the screw 20. By the design, the screw 20 is suitable for an inner hexagonal wrench and a screwdriver at the same time.

The wire is adapted to be threaded through the bushing block 10 through the wire receiving hole and between the bushing block 30 and the upper end wall 12, and the threaded rod 20 is tightened against the outside of the bushing block 10 by a allen wrench or a screwdriver, thereby locking the wire between the bushing block 30 and the upper end wall 12.

The pad 30 increases the pressing area, so that the lead is pressed more stably, and the pad 30 can be connected to the pressing end of the screw 20 through the pin 40, so that the welding process is omitted, the structure is simple, and the processing difficulty is low. In addition, the end of screwing of screw rod 20 is equipped with interior hexagonal groove 22 and a style of calligraphy groove 21 simultaneously, but the multiple instrument of screwing of adaptation, just interior hexagonal groove 22 can realize great locking torque for wire pressing frame 10 can be applicable to the wire that the sectional area is great.

Specifically, the upper end wall 12 is formed by bending, laminating and punching end portions of the two side walls 13 towards each other, so that the structural strength of the wire pressing frame 10 is increased, the thread distance of the threaded hole is increased, and a better fastening effect can be achieved.

Preferably, the diameter of the through hole 31 is gradually reduced from the lower surface to the upper surface of the pad 30, which is beneficial to guiding the pin rod 41 of the pin 40 to pass through, and improves the processing efficiency.

Preferably, the edge of the pad 30 is tilted from the center of the pad 30 to the lower end wall 11, which is beneficial for fixing the wire with a larger cross section.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention.
