AI Technical Summary

Problems solved by technology

These traditional processing methods use imported equipment. First, the imported equipment is expensive, the processing procedure is complicated, and the processing efficiency is low. Second, the multi-tooth key angle control is inaccurate, resulting in inaccurate multi-head tooth insertion.

Embodiment Construction

[0020] Below in conjunction with accompanying drawing, processing method of the present invention will be further described.

[0021] Take the processing of the tooth key, keyway and concealed convex key of the bayonet type electrical connector headstock and tailstock shown in the drawings as an example, where φA is 23mm, φB is 28mm, and φC is 20mm. The processing steps are:

[0022] 1. Fix the metal pipe with an outer diameter of φ40mm and an inner diameter of φ20mm on the lathe for central reaming, expand the inner diameter to φ22mm, and finish the inner wall to φ23±0.03mm;

[0023] 2. Take off the rough-processed metal tube, put it on the die mandrel with the shape of a hidden convex key, and fix it in the tooling of the punching machine, start the punching machine, and squeeze the outer wall of the metal tube inward through the punch to form a dark convex Key, that is, the dark convex key on the inner wall of the headstock or tailstock, such as figure 1 shown in the dark ...

Abstract

A method for machining the tooth key, key slot and hidden convex key of pin-type electric connector includes such steps as broaching a metal tube, turning its inner surface, punching on the external surface to form a hidden convex key, using it as locating reference, turning external surface of head, using multi-angle female die to cut it to form a multi-angle tooth key, turning another end of metal tube, turning spiral threading, turning internal surface, and using multi-angle male die to cut the internal surface to form multi-angle key slot.

Description

technical field [0001] The invention relates to a processing method for a tooth key, a keyway and a recessed convex key in an electrical connector, in particular to a processing method for a bayonet-type electrical connector with a multi-angle splined key and a keyway precisely matched therewith and an inner cavity convex key. Background technique [0002] Whether it is strong electricity or weak electricity, as long as electricity is used, there are electrical connectors. Since the use of electricity is directly related to our own safety, people have higher and higher requirements for the safety and defense performance of electrical connectors. In the prior art, multi-angle splines and keyways are invented to control the docking angle of connectors, and hidden convex keys control their own docking direction, thus endowing electrical connectors with blind insertion, similar to the function of mis-insertion between connectors. The key control docking in electrical connectors...
