General jack contact element

Abstract

The invention discloses a general jack contact element consisting of a jacket, a contact ring arranged in the jacket, and a pin connected with the lower end of the jacket. A locating slot is arranged at the upper end of the pin, the contact ring is a cylindrical part formed by rolling and combining two pairs of parallel elastic arms, the size of the upper end of the contact ring is larger than that of the lower end of the contact ring, the upper end of the contact ring is in interference fit with the jacket, locating teeth used for realizing the peripheral location of the contact ring are arranged at the lower end of the contact ring and are clamped in the locating slot. The general jack contact element is simple in structure, reasonable in design and reliable in contact, can better realize the plugging match with a square contact pin and a circular contract pin, and has stronger novelty and practicability.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, and in particular relates to a universal jack contact. Background technique [0002] There are many types of connector contacts, and the commonly used ones are cylindrical contacts, stranded wire elastic pin contacts, wire spring socket contacts, crown spring socket contacts and reed socket contacts. Among these contacts, the wire spring socket contact, the crown spring socket contact and the stranded elastic pin contact are simply supported beam mechanical models, which have high contact reliability; the reed socket contact It is a cantilever beam mechanical model, and the contact reliability is low. In addition, the reed socket contacts are stamped and are only suitable for mating with square pin contacts. The existence of these factors has affected the promotion and use of this type of contact to a certain extent. Contents of the invention [0003] The technical problem to b...

Problems solved by technology

Among these contacts, the wire spring socket contact, the crown spring socket contact and the stranded elastic pin contact are simply supported beam mechanical models, which have high contact reliability; the reed socket contact It is a mechanical model of a cantilever beam, and the contact reliability is low

In addition, the reed socket contacts are punched and are only suitable for mating with square pin contacts.

The existence of these factors has affected the promotion and use of such contacts to a certain extent.
