Filter electrical connector and grounding spring leaf thereof

Abstract

The invention discloses a filter electrical connector and a grounding spring leaf thereof. The outer electrodes of a plate capacitor of the filter electrical connector are conductively connected with a connector shell by the grounding spring leaf. The grounding spring leaf comprises an annular or C-shaped banded spring leaf body surrounding the four side faces of the plate capacitor. Elastically extendable / retractable elastic wall parts are integrally formed on the outer walls of the four side faces of the spring leaf body, and are tightly pressed against the connector shell. The outer electrodes are arranged on the end face of at least one end of the plate capacitor. Turned-over edges extended into a space enclosed by the spring leaf body are integrally formed at one or two of the top and bottom ends of the spring leaf body in an axial direction, are in corresponding hooking fit with the end face, with the outer electrodes, of the plate capacitor and are conductively attached to the outer electrodes on the end face. In the grounding spring leaf provided by the invention, the turned-over edges can be ensured to be hooked with the lateral surface of the plate capacitor and attachedto the outer electrodes of the plate capacitor in assembly, and the elastic wall parts elastically contact with the shell, thereby realizing reliable connection between the plate capacitor and the shell.

Description

technical field [0001] The invention relates to the technical field of electrical connectors. Background technique [0002] In the existing filter electrical connectors using plate capacitors, the external electrodes of the plate capacitors and the shell of the filter electrical connector need to be grounded through conductive contact, and the plate capacitors also need to be fixed in the shell. In the existing structure, welding or conductive adhesive bonding is generally used to realize the connection between the plate capacitor and the shell, which is inconvenient to operate and difficult to ensure consistent quality. C-shaped shrapnel, but the shrapnel is not easy to form a whole with the plate capacitor, the assembly operation is still inconvenient, and the inner ring of the shrapnel is difficult to contact with the outer electrode of the plate capacitor. [0003] In addition, the plate capacitor of the existing filter electrical connector is provided with a contact as...

In the existing structure, welding or conductive adhesive bonding is generally used to realize the connection between the plate capacitor and the shell, which is inconvenient to operate and difficult to ensure consistent quality. C-shaped shrapnel, but the shrapnel is not easy to form a whole with the plate capacitor, the assembly operation is still inconvenient, and the inner ring of the shrapnel is difficult to contact with the outer electrode of the plate capacitor.

[0003] In addition, the plate capacitor of the existing filter electrical connector is provided with a contact assembly hole for the contact to penetrate and make conductive contact. The contact is divided into two types: pin contact and jack contact. The existing jack contact Due to the central jack, the diameter of the contact piece is relatively large, resulting in a relatively large diameter of the contact installation hole in the corresponding plate capacitor. , will not be able to be fabricated due to the proximity of adjacent contact mounting holes
