Abstract

A locking electrical connector assembly for locking together a plug and a header. The assembly includes a plug having a plug body, a first electrical contact located the plug body capable of receiving a wire, an opening in the plug body capable of receiving a second electrical contact from a header where the second electrical contact makes electrical connection to the first electrical contact, a first interlocking portion provided on a first side of the plug body for interlocking with a corresponding first interlocking portion of the header, and a second interlocking portion located on a second side opposite from the first side for interlocking with a corresponding second interlocking portion of the header. The header includes a first surface having the corresponding first interlocking portion for interlocking with the first interlocking portion of the plug, a second surface having the corresponding second interlocking portion for interlocking with the second interlocking portion of the plug, and a third surface integrated with the first and the second surfaces having an opening for housing the second electrical contact.
