Integrated hyperbolical spring-bearing receptacle contact component and its technological process

Abstract

The invention discloses a kind of integral hyperbolic spring socket contact component, which belongs to electric connector contact component. Comparing with the current technology, the invention has following merit and active effect: it uses single leave rotary hyperbolic contact mode, it contacts with the pins with multiaspect envelope, the dynamic contact resistance is stable, it has characters of impact resisting, anti-vibration, bearing large current, soft plug, and contact resistance is small. Because the two ends of the entire metal piece are connected together in parallel and bear the current, thus the current bearing ability is upgraded greatly, and it can carries on hot plug. Because the component is only made up of a layer of thin wall bushing, it is simple, the volume of contact component can be reduced, the contact is more reliable, reduces the consumption of copper.

Description

Technical field [0001] The invention belongs to an electric connector contact piece, in particular to an integrated hyperboloid strip spring socket contact piece. Background technique [0002] At present, the existing electrical connector contacts with good reliability and stability have single-leaf rotary hyperboloid wire spring jacks, which are evenly enveloped by a group of elastic metal wires arranged in a single-leaf rotary hyperboloid structure. On the surface of the pin inserted into it, it is a multi-line envelope contact. The socket contact with this wire spring structure is composed of four parts: an inner sleeve, an outer sleeve, a rear sleeve, and an elastic metal wire. A group of elastic metal wires arranged in a single-leaf rotary hyperboloid are coaxially installed in the inner sleeve, and each The two ends of a metal wire extend out of the two ports of the inner casing, and are bent back along the outer cylindrical surface of the inner casing. The bending pa...

Problems solved by technology

[0003] This kind of wire spring structure has the following disadvantages: (1) the contact resistance of the sleeve method is large, and the tensile force is poor, and the front and rear sleeves are easily separated from the pressure point by the tension, resulting in connection failures and accidents; If there are too many, the volume cannot be further reduced, which is not conducive to the development of miniaturization and densification; (3) the processing technology is complicated and the precision requirements are high, resulting in low product qualification rate and high cost; (4) it is impossible for the elastic metal wire to It is very thick, making it difficult for each wire to withstand the impact of a large current; (5) The phenomenon of broken wires during use cannot be solved

When the pin is inserted into the crown band, the elastic metal strip is in contact with the surface of the pin at the waist circle. Because of structural limitations, it cannot be evenly wrapped on the surface of the pin like the wire spring wire in the wire spring structure. The elastic metal strip does not form a single-leaf hyperboloid of revolution, and its contact performance cannot be compared with the multi-line envelope contact method of the single-leaf hyperboloid of revolution
