To help maintain and improve signal integrity, a connector housing can include one or more of the following: asymmetric keying features, asymmetric alignment features, and alternating stitched electrical contacts.

An electrical connector assembly includes a receptacle housing having a retaining device with a coupling hook portion and a plug housing configured to be mated and locked with the receptacle housing. The plug housing has a lever movable from a first position in which the plug housing and the receptacle housing are unlocked to a second position in which the plug housing is locked with the receptacle housing. The lever is rotatably mounted about a shaft arranged in and passing through the plug housing. The coupling hook portion is configured to engage with the shaft and, in the second position, the shaft is in abutment with the coupling hook portion to positively lock the plug housing and the receptacle housing together.

The present invention discloses a terminal stand that includes a base body, a movable part, a metal elastic part, a first signal element and a second signal element. The base body includes a first receiving slot and a second receiving slot. The metal elastic part is disposed in the first receiving slot. One end of the metal elastic member includes two first abutments. The first signal element is disposed in a second receiving slot. One end of the first signal element includes a first contact portion and a second abutment. The second signal element is disposed in the second receiving slot. When the movable member is pressed, the movable member drives the two first abutments to move, and the abutment drives the second abutment to move, with the first contact portion leaving the second contact portion, and the signal circuit is in an off-state state.
