AI Technical Summary

Technical Problem

In the existing technology, cylindrical conductors A and B cannot be directly welded due to their different materials, and conventional plastic deformation crimping may damage the encapsulation of conductor A. The connection position is prone to loosening under high and low temperature cycles and vibration.

Method used

A double-threaded and tapered clamping electrical connector structure is adopted, including a connector middle body, a spindle, a locking component and an anti-loosening strip. The connection of conductors of different materials is achieved through the cooperation of nuts and inner and outer tapered tubes, and loosening is prevented through limiting sections and slit design.

Benefits of technology

It effectively achieves stable connection of conductors of different materials, avoiding loosening caused by high and low temperature cycles and vibration, and has a simple and practical structure.

Abstract

The application relates to the technical field of electric connectors, and particularly discloses a double-end thread and cone compression electric connector structure and an assembling method, which are used for the connection of two cylindrical conductors and comprise a connector middle body, shafts arranged on the two sides of the connector middle body and coaxially connected with the two cylindrical conductors respectively, and locking assemblies sleeved on the outer cylindrical surfaces of the shafts and used for locking the shafts and the cylindrical conductors; the locking assemblies are arranged in one-to-one correspondence with the cylindrical conductors; the locking assemblies comprise nuts sleeved on the outer cylindrical surfaces of the shafts, outer conical tubes which are sleeved on the outer cylindrical surfaces of the shafts, located on the sides of the nuts away from the connector middle body and cut into two halves, and inner conical tubes which are sleeved on the outer cylindrical surfaces of the shafts and matched with the outer conical tubes. The application can effectively realize the connection between cylindrical conductors made of different materials and avoid the loosening of the cylindrical conductors.
