High density sealed electrical connector with multiple shielding strain relief devices

摘要

An electrical connector system includes mating pin and socket connectors each designed for increased contact density to improve performance of high-speed data transfer. The connectors include features for retaining a plurality of pin or socket contacts in a ganged, co-aligned configuration and for shielding groups of contacts from one another to reduce interference and crosstalk. The connectors further include features for providing strain relief to the internal wires and/or cables. One of the connectors may include a plug insert with cantilevered fingers extending therefrom that contact a conductive surface of the mating connector to provide a mechanical connection and a low-impedance pathway between the mating connectors for grounding and shielding. The connectors are designed to be readily assembled and disassembled for repair or rework without the use of special tools.

主权项

1. An electrical connector, comprising:
an electrically conductive plug insert having a plurality of contact-receiving cavities extending in an axial direction through the plug insert, each of the cavities having a front opening at a front face and a rear opening at a rear face of the plug insert; a plurality of electrically insulating sheaths, each sheath carrying a pair of electrical contacts in a spaced-apart relation such that each electrical contact is in alignment with one of a pair of contact apertures in a front wall of the sheath, each sheath sized for insertion into one of the contact-receiving cavities of the plug insert so as to position the contact apertures of the sheath in alignment with the front opening at the front face of the contact-receiving cavity; a plurality of electrically conductive shield ferrules each having a front end, a rear end opposite the front end, a flexible skirt at the rear end, and multiple recesses arranged around an inner surface of the shield ferrule adjacent the front end, each recess receiving and retaining at least a portion of one of the sheaths such that each of the shield ferrules retains multiple sheaths; and an electrically conductive shield housing having a base portion and a head portion, the shield housing having a plurality of cylindrically-shaped barrels extending in the axial direction from an exterior surface of the head portion, the housing further including a plurality of ferrule-receiving cavities extending in the axial direction through the shield housing, each cavity having a rear opening on a rear face of the base portion and a front opening at a front end of each of the barrels, wherein the rear opening of the cavity receives and retains the flexible skirt of the shield ferrule.
