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

Embodiment Construction
[0024] As shown in Figure 2, the elastic washer of the impeller is formed by bending one side of the elastic rectangular conductive material strip to the opposite side to form a circular body. Several impellers are uniformly stamped on the rectangular conductive material strip, and each impeller is backed at the same angle. It protrudes outward toward the central axis of the annular body, one side of the impeller is connected to the rectangular conductive strip, and the remaining sides of the impeller are separated from the rectangular conductive strip.
[0025] Preferably, there are 6 groups of impellers, and the distance between the centers of two adjacent groups of impellers is 60°. Each group of impellers includes A rotating surface, B rotating surface, and C rotating surface sequentially connected to the rectangular conductive strip.
[0026] The surface of revolution A is a curved surface formed by rotating the straight generatrix A around the central axis of the circular...

The invention provides an impeller elastic washer and a high continuous small torsion coaxial connector including the washer, which realize high continuity of signal transmission and obtain relatively small torsion. The elastic washer of the impeller is formed by bending one side of the elastic rectangular conductive material strip to its opposite side to form a circular body. Several impellers are uniformly stamped on the rectangular conductive material strip, and each impeller faces away from the circular body at the same angle. The central axis of the impeller protrudes outward, one side of the impeller is connected with the rectangular conductive strip, and the other sides of the impeller are separated from the rectangular conductive strip. The coaxial connector includes a nut, a main body, a central post and the above-mentioned elastic washer of the impeller. The central post is located inside the nut and is stuck on the end surface of the front slot inside the nut. The main body is sleeved on the central post and the front end of the main body is pressed into the nut. The end face of the rear card slot, the impeller elastic washer is located between the front card slot and the rear card slot, and between the nut and the central column. The present invention improves the continuous performance of signal transmission, reduces the torsion force, and improves the production capacity.
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...
