Combined female contact element

Abstract

The invention discloses a combined female contact element, which comprises a head part and a tail end. The head part is a cylinder body, and a step hole, an assembly hole, a nick and a flange are arranged on the head part, wherein the nick is deformed to be wedged. A cylindrical head is arranged at the tail end. The cylindrical head of the tail end penetrates through the step hole of the head part, is spliced with the assembly hole, and is in interference fit with the assembly hole. An integrated contact element is divided into a contact element head part and a contact element tail end, the contact element head part is designed and manufactured in a standard way, the contact element tail end is in interference fit with the contact element head part through a standard cylindrical head, and the nick is axially reserved in the head part, so that the elastic performance and anti-fatigue performance of the contact element head part are improved, and the aims of interface standardization of a contact element of a connector, improvement in connection reliability and remarkable reduction in coating cost are fulfilled.

Description

technical field [0001] The invention relates to a contact piece in the technical field of electrical connectors, in particular to a combined female contact piece. Background technique [0002] The electrical connector realizes the connection or disconnection of the transmission signal through the contact or separation of the contact, and the contact is the core component of the electrical connector. In the prior art connector, the head and the tail end are designed as an integrated structure. Due to the different termination methods and installation dimensions of the tail end, the contact pieces of the electrical connector have different shapes and various specifications. At the same time, due to the structural design Missing, the contact piece of the cylindrical barrel in the prior art has a notch closed at both ends in the axial direction on the periphery of the cylindrical barrel, resulting in unsatisfactory elastic performance and fatigue resistance of the head of the co...

Problems solved by technology

In the prior art connector, the head and the tail end are designed as an integrated structure. Due to the different termination methods and installation dimensions of the tail end, the contact pieces of the electrical connector have different shapes and various specifications. At the same time, due to the structural design Missing, the contact piece of the cylindrical barrel in the prior art has a notch closed at both ends in the axial direction on the periphery of the cylindrical barrel, resulting in unsatisfactory elastic performance and fatigue resistance of the head of the contact piece, which makes the work of the connector Reliability is reduced. In addition, in order to prolong the service life of the contacts, it is necessary to coat the surface of the contacts with precious metals, resulting in a significant increase in the cost of coating precious metals; in short, it is not conducive to the standardization of the connector interface. high
