Spring-wrapped jack contact member

Abstract

A spring-wrapped jack contact member includes a cylindrical jack and a contact ring. The sidewall of the jack is provided with a window. The contact ring wraps the window on the outer wall of the jack. The contact ring is provided with a contact spring. The contact spring is bent towards the inside of the jack and protrudes into the jack through the window. The contact ring wraps a contact section so as to achieve a wide insertion force range, a low process requirement, high contact reliability. Further, the spring-wrapped jack contact member is simple in structure, small in size, practical and convenient, and can economically meet the requirement of a situation for a long mechanical life and large-scale vibration.

Description

technical field [0001] The invention belongs to the field of electrical connectors, and in particular relates to a spring-wrap socket contact. Background technique [0002] Invention patent ZL201210273857.1 discloses an existing crown spring socket contact, its structure is as follows Figure 11 As shown, it is composed of a tubular socket 1, a crown spring contact ring 2 and a pin 3. One end of the crown spring contact ring 2 is provided with a slot and a contact strip, which is axially placed inside the tubular socket 1 and slotted The parts are fixed by pressure riveting, welding and other methods. Since the crown spring contact ring 2 is fixed inside the tubular socket 1, the insertion force and separation force of this structural form are inevitably limited by the size of the pre-deformation and greatly affected by the machining accuracy. If the deformation range is small, then If the pressure is small, the contact is unreliable; if the deformation is large, the pressu...

Problems solved by technology

Since the crown spring contact ring 2 is fixed inside the tubular socket 1, the insertion force and separation force of this structural form are inevitably limited by the size of the pre-deformation and greatly affected by the machining accuracy. If the deformation range is small, then The pressure is small and the contact is unreliable; if the deformation is large, the pressure will be large and the insertion force will be large, not only the connector is difficult to butt, but also the deformation will cause plastic degeneration, resulting in unreliable contact

Therefore, this type of socket contact is not only difficult to manufacture, but also has low contact reliability and relatively high manufacturing costs. It cannot be widely used in occasions that require economical, high mechanical life, and large-scale vibration.
