Abstract

A small high-reliability wire spring hole fisheye crimping type jack comprises a front sleeve, a rear sleeve and a jack pipe. A crimping annular groove is formed in the middle of the outer circular surface of the jack pipe, one end of the outer circular surface of the jack pipe is inserted into the inner pipe wall of the front sleeve, and the other end of the outer circular surface of the jack pipe is inserted into the inner pipe wall of the rear sleeve; orifices of the front sleeve and the rear sleeve, which are positioned in the crimping ring groove, are crimped with the crimping ring groove; and a fisheye structure is arranged at one end, far away from the jack pipe, of the rear sleeve. According to the invention, through a crimping mode, the plugging and pulling-out force of the jack is increased, the processing size precision requirement of the jack is reduced, and the yield is improved; by arranging the wire spring wire in the jack tube, the reliability of electrical connection between the jack and the pin is enhanced, so that the jack has the characteristics of high vibration level, long plugging life, flexible plugging force, reliable contact part and small contact resistance. The structure is compact, and the high-density requirement of the jack is met; and fisheye crimping is adopted, so that the problem of impedance mismatching at the via hole is solved.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a small and highly reliable wire spring hole fish-eye crimping socket. Background technique [0002] In order to achieve high-speed, high-density, miniaturized, and high-reliability connectors, a small and highly reliable socket contact is required, which is characterized by a smaller outer diameter, higher reliability, and fisheye crimping at the end (for To achieve high-speed transmission, there will be problems such as impedance mismatch when welding at the end. At present, only the fish-eye crimping termination method) can be used to integrate the jack contact. However, the current domestic and foreign contact jacks have the following characteristics: Large-diameter contact pieces (low reliability), end welding (unable to achieve high-speed transmission), there is no jack that integrates the three characteristics of small outer diameter, high reliability, and end fisheye c...
