Electrical connector

A plug connector 1 and a receptacle connector 5 are provided with two poles of power plug contacts 30, 30 and power receptacle contacts 70, 70, respectively, at end portions of their housings 10 and 50 on the right and left sides of signal contacts 20, 60, and 60'. The right and left end portions of the housings 10 and 50 are provided with connector securing metal parts 40 and 80 made of a conductive material, which cover the power contacts 30 and 70, respectively, whereby the connectors can be attached to circuit boards. When both connectors 1 and 5 mate together, the connector securing metal parts 40 and 80, the power contacts 30 and 70, the contacts 60, 60', and 20 are successively connected to each other.

Electrical connector with shielded power contacts

An electrical connector assembly comprises a plug connector half 1 and receptacle connector halves 5 and 9, including a receptacle connector half 5 with power transmission contacts and a receptacle connector half 9 without any power transmission contact. These receptacle connector halves are alternatively used in correspondence with the application. The receptacle connector half 5 with power transmission contacts is provided with two polar receptacle contacts 70 for power transmission in a receptacle housing 50. These receptacle contacts 70 for power transmission are brought into contact with plug contacts 30 for power transmission when the plug connector half 1 and the receptacle connector half 5 are intermated. On the other hand, the receptacle connector half 9 without any power transmission contacts is provided with accommodation spaces 57 in a receptacle housing 50'. These accommodation spaces accommodate said plug contacts 30 for power transmission when the plug connector half 1 and the receptacle connector half 9 are intermated.

Connector assembly with alternate housings with and without power

An electrical connector has an insulative housing, a fixture, and a shield. The fixture is used for fixing this insulative housing on a circuit board, and the shield is to cover the insulative housing. The insulative housing, which is made of an electrically insulating material, comprises a main body and an engaging portion, which protrudes forward from the main body to engage with a matable connector. The insulative housing also comprises fixture retaining slots, which extend through the main body in the vertical or to-and-fro direction at the lateral ends of the main body of the housing. Into each of these fixture retaining slots, a fixture, which is made of an electrically conductive metallic material, is press-fit to fix the insulative housing onto a circuit board. The shield, which is made of an electrically conductive metallic material, comprises a peripheral portion and contact portions in a one-piece body. The peripheral portion covers the perimeter of the engaging portion of the insulative housing, and each of the contact portions extends into a respective fixture retaining slot. With this construction, each fixture is retained in contact with a respective contact portion in a respective fixture retaining slot grounding the shield when the electrical connector is mounted on a circuit board with the fixtures being surface-mounted onto grounding pathways on the circuit board.
