Asymmetric shielding triangular spring

Abstract

An asymmetric shielding triangular spring is in a closed ring shape, and an inner hole of the spring is a cable assembly hole. The spring is an inclined elastic piece formed by winding a metal wire, the projection of the section of the spring is an asymmetric triangle, each section of the spring is in an inclined state at a certain angle, and a contact point between the spring and the cable is inclined and floats. Each section of the triangular spring is in an inclined state at a specific angle, the cable insertion force is smooth, and the triangular spring is wide in adaptation range and high in compatibility for shielding cables of different specifications. Each section of the triangular spring is inclined at a specific angle, so that the contact area between the triangular spring and a shielding layer of a shielding cable is large, the contact is sufficient and reliable, and the triangular spring is matched with a corresponding metal shell for assembly, so that the spring has the capability of bearing 20KA lightning stroke surge besides a common electromagnetic shielding function.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors and cable joints, and in particular relates to an asymmetric shielding triangular spring. Background technique [0002] With the accelerated popularization of 5G communication technology, the application of power connectors used in communication base stations in the telecommunications industry to supply power to each module of the base station is also becoming more and more popular. Coupled with the development of the integration technology of each module of the 5G base station, higher requirements are put forward for the input power of the module power supply, which promotes the power connector to be miniaturized, high-power, with shielding efficiency, strong versatility, low cost, and high reliability. And the direction such as simple structure develops. [0003] The patent CN208461128U explains the triangular spring used for the traditional cable joint, which only has the functio...

Problems solved by technology

In engineering applications, this method leads to excessive cable insertion force, time-consuming and labor-intensive installation, and poor operability; and because cables with larger outer diameters require greater elastic deformation at each section of the spring during insertion, resulting in Insertion is very difficult; when the wire diameter continues to increase, each section of the spring will undergo plastic deformation during cable insertion, resulting in failure of the triangular spring

Therefore, the triangular spring described in the patent CN 208461128U has a narrow cable adaptation range and low versatility, and can only be used for cables with specifications within a specific narrow range.
