Elastic contact part and electric connector employing same

Abstract

The invention relates to the field of electric connectors, in particular to an elastic contact part and an electric connector employing the same. The elastic contact part comprises a tail conductor, a contact part and an elastic part, wherein the elastic part is used for providing the contact part with elastic force; a contact pin extending along the axial direction is arranged at the front end of the tail conductor; the contact part comprises a contact part body; a contact end is arranged at the front end of the contact part body; a shrinking structure capable of extending along the axial direction of the contact pin and elastically shrinking along the radial direction of the contact pin is arranged at the rear part of the contact part body; and the shrinking structure and the contact pin are in elastic sliding contact. The contact pin extending along the axial direction is arranged at the front end of the tail conductor; and the shrinking structure capable of shrinking along the radial direction of the contact pin is arranged at the rear end of the contact part body; and the contact part sleeves the contact pin through the shrinking structure on the contact part body, so that the contact part and the contact pin are tightly laminated; and the electric connection reliability between the contact part and the contact pin is strengthened.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to an elastic contact piece and an electrical connector using the elastic contact piece. Background technique [0002] In the prior art, there is a type of elastic contact, which ensures the reliability of the electrical connection by setting a spring on the contact, for example, a telescopic electrical connection disclosed in a Chinese patent with the announcement number CN 202749553 U and the announcement date of 2013.02.20 The pin includes a moving contact, a tail contact and an outer shell. The moving contact is the contact piece, and the tail contact is the tail conductor. One end of the contact piece is placed in the cavity formed after the outer shell is connected to the tail conductor. In the body, the contact piece is slidingly fitted with the inner wall of the outer shell, and the inner cavity of the outer shell is provided with an elastic piece for providing elastic f...

The moving contact is the contact piece, and the tail contact is the tail conductor. One end of the contact piece is placed in the cavity formed after the outer shell is connected to the tail conductor. In the body, the contact piece is slidingly fitted with the inner wall of the outer shell, and the inner cavity of the outer shell is provided with an elastic piece for providing elastic force to the contact piece, that is, a spring, so that the contact piece can be in the inner cavity of the outer shell Axial movement, but during use, this gap will reduce the reliability of the electrical connection between the moving contact and the outer shell
