Spiral spring type socket

Abstract

The invention discloses a spiral spring type socket, and belongs to the field of electric connectors. A specific technical scheme is as follows: the spiral spring type socket comprises an insulating outer sleeve, an inner sleeve and a plurality of wire springs; the inner sleeve is of a vertically-through cylindrical structure; a plurality of groups of through holes are formed in the side wall of the inner sleeve from top to bottom; each group comprises two layers of through holes which are formed in a staggered manner; each layer of through holes are uniformly distributed on the same horizontal plane; each wire spring sequentially penetrates through the same group of through holes along the circumferential direction of the inner sleeve and is connected end to end to form a wire spring wirering; the inner sleeve provided with the wire spring wire ring is arranged inside the insulating outer sleeve, the inner sleeve is fixedly connected with the insulating outer sleeve, and the inner sleeve and the plurality of wire springs are made of conductive materials. The multi-layer wire spring wire spiral layout is adopted, so that the plug force change of a jack in the operation process ismore stable, an impact peak value is reduced, and the wear degree of a contact pin and the jack is reduced.

Description

technical field [0001] The invention belongs to the field of electrical connectors, and in particular relates to a helical wire spring socket. Background technique [0002] Various electrical connectors are widely used in various electrical circuits. The number of electrical connectors used on an aircraft can range from hundreds to thousands, involving tens of thousands of circuits. In addition to meeting the electromagnetic performance requirements, electrical connectors should also ensure reliable contact and easy maintenance in harsh environments. The reliability of a single electrical connector directly affects the normal operation of the circuit system and involves the safety of the entire host. At present, in electrical connector products, wire spring sockets are widely used because of their high stability and high reliability. The traditional wire spring socket has the following characteristics: multiple elastic metal wires are arranged in the socket according to t...

Problems solved by technology

However, in actual use, there will be a large peak in the insertion force that pushes the pin into the jack; and when the pin is stably connected to the jack, there is an objective error in the manufacture of the jack, which makes the pin and the jack The effective contact area between them does not meet the design requirements, resulting in the problem that the connector in the working state suddenly loosens when it is affected by external factors such as shock and vibration.
