  • Publication number: 20150087165
    Abstract: A receptacle connector includes an insulative housing, a number of contacts fixed to the insulative housing and a shell enclosing the insulative housing. The insulative housing includes a main portion, a mating portion and a fixing portion. The shell includes a first metallic shell and a second metallic shell fastened to the first metallic shell. The first metallic shell encloses the mating portion and cooperatively defines therebetween a mating space for receiving a plug connector. The second metallic shell defines a hollow space in which the first metallic shell is at least partly received. As a result, the first metallic shell and the second metallic shell have a strong structure which is stable for mating with the plug connector.

  • Patent number: 8932082
    Abstract: An electrical connector mountable on a printed circuit board includes an insulative housing and pairs of power contacts. Each power contact has a contacting portion, a tail portion and an intermediate portion interconnecting the contacting portion and the tail portion. The intermediate portion is provided with a retention element in a rear edge thereof extending towards an inside wall of a passageway defined through the insulative housing.
