Impeller elastic washer and high-continuity small-torsion coaxial connector containing same

Abstract

The invention provides an impeller elastic washer and a high-continuity small-torsion coaxial connector containing the same. According to the invention, small torsion is acquired while realizing high continuity in signal transmission. The impeller elastic washer is characterized in that one side of a rectangular conductive material band is bent towards the opposite side thereof to form a circular body, a plurality of impellers are uniformly punched on the rectangular conductive material band, each impeller protrudes outward in a mode of backing against a center axis of the circular body by the same angle, one side of the impeller is connected with the rectangular conductive material band, and the remaining sides of the impeller are separated from the rectangular conductive material band. The coaxial connector comprises a nut, a main body, a center column and the impeller elastic washer, wherein the center column is located inside the nut and clamped at the end face of a front clamping slot inside the nut, the main body is arranged on the center column in a sleeved mode, the front end of the main body is laminated in the end face of a rear clamping slot inside the nut, and the impeller elastic washer is located between the front clamping slot and the rear clamping slot and between the nut and the center column. According to the invention, the continuity performance of data transmission is improved, the torsion is reduced, and the productivity is improved.

Description

technical field [0001] The invention belongs to the field of coaxial connectors, and in particular relates to an impeller elastic washer and a high continuous small torsion coaxial connector including the washer. Background technique [0002] Radio frequency coaxial connectors (hereinafter referred to as RF connectors) are generally considered to be a component attached to a cable or installed on an instrument, as a component for electrical connection or separation of a transmission line. It belongs to audio and video products. Simply put, it mainly acts as a bridge, so it has high requirements for the continuity of signal transmission, especially in harsh conditions such as violent storms. However, products with high signal transmission continuity basically have a relatively large torque, and the nut head of the connector does not rotate smoothly, which affects the user's use. However, products whose nut heads are easy to rotate have poor signal transmission continuity, d...

AI Technical Summary

Problems solved by technology

During the twisting rotation of the nut, the contact point on the washer encounters high resistance and even jams

At the same time, this method has high requirements on the precision of product parts and connector assembly equipment, and the assembly process is strict. If there is a slight deviation, the entire set of parts will be discarded, and the connector assembly equipment will be repaired.

Therefore, in the process of production and processing, product quality and production efficiency cannot be guaranteed
