Abstract

This invention discloses a connector, including a base and an upper cover connected to the base. A conductive connecting core is disposed on the base, with an upper connecting end and a lower connecting end formed at its upper and lower ends, respectively. Correspondingly, a connecting window is provided on the upper cover for inserting a cable. The conductive connecting core includes a hollow core body, with two extended edges pressed into the upper and lower ends of the core body to increase the contact area of ​​the core body. A threaded connector is disposed inside the core body. This application makes the threaded connector and the core body into two independent structures. First, the threaded connector is placed in the core body, and then the two ends of the core body are flattened. This ensures that the two ends of the core body have a sufficiently large contact area, while avoiding excess material waste in the middle section of the core body. Furthermore, it avoids quality problems such as burrs caused by directly tapping the core body.

Description

Technical Field

[0001] This invention relates to the field of cable connector technology, specifically to a connector and its manufacturing method. Background Technology

[0002] Cable connectors are used to connect segmented bypass cables to quickly extend or shorten their length. A cable connector includes a copper conductive core, which is a key component. Existing copper conductive cores require threaded sections at both ends for connecting the cables. Both ends of the core must have sufficient cross-sectional area to ensure adequate contact with the cables. Current manufacturing processes use a monolithic copper cylindrical core, with direct tapping at both ends to create the threaded sections. This process easily creates burrs on the threads, affecting product quality. Furthermore, the required contact area at both ends of the core is equal to its cross-sectional area. If a larger contact area is needed at both ends, identical cross-sectional areas are required, leading to a waste of raw materials due to the larger cross-sectional area in the middle section.
