Head shrinkage tool of ultra-small semi-hard cable

Abstract

The invention relates to a head shrinkage tool of an ultra-small semi-hard cable. The head shrinkage tool of the ultra-small semi-hard cable comprises a stamping work module, a stamping driving part,a fixed frame, a sliding frame and a sliding driving part, and is characterized in that the stamping work module comprises an upper die and a lower die, and is characterized in that the upper die is acuboid with a V-shaped protrusion on the lower surface and provided with a positioning hole; the lower die comprises a fixed die and a sliding die, a V-shaped groove matched with the V-shaped protrusion of the upper die is formed in the upper surface of the lower die, the V-shaped groove is formed by splicing the fixed die and the sliding die, a positioning groove and a positioning protrusion which are matched with each other are formed in the splicing face of the fixed die and the sliding die, a guide groove is formed in the V-shaped groove, and the groove surface of the guide groove is vertical. According to the head shrinkage tool of the ultra-small semi-hard cable, in the specific application, the process requirement of the head shrinkage of an outer conductor of the ultra-small semi-hard cable is met by adopting a punching head shrinkage mode, and the technical difficulty that large-size semi-hard cable head shrinkage equipment cannot adapt to the head shrinkage of the ultra-small semi-hard cable is solved.

Description

technical field [0001] The invention belongs to the technical field of cable production, and in particular relates to the technical field of cold processing for pressing a fine copper tube into a solid body with a smaller circumcircle radius. Background technique [0002] Ultra-small semi-rigid coaxial cable refers to the cable with the total outer diameter of the cable less than 1mm. The outer conductor uses a copper tube with an outer diameter of less than 1.4mm and a wall thickness of less than 0.13mm. It is the miniaturization and integration of electronic equipment to microsystems The development of globalization puts forward new requirements and development trends in the field of coaxial cables. The semi-rigid coaxial cable adopts the ideal coaxial cable structure, which makes the cable have outstanding electrical properties such as low attenuation, small standing wave, and good shielding performance. It is a widely used coaxial cable structure. [0003] Before the ca...

Problems solved by technology

[0007] The problem to be solved by the present invention is to overcome the problems existing in the prior art, and provide a shrinking tool suitable for ultra-small semi-rigid cables, so as to solve the problem that when the size of the cable is very small, it is difficult to implement the method of using the rigidity of the copper tube itself to push the feed , it is difficult to avoid the problem that the copper tube slips out of the mold during the compression process
