Abstract
Abstract A two-piece connector having a header, a receptacle, a first group of contacts incorporated in the header, and a second group of contacts incorporated in the receptacle. The header can be inserted into the receptacle. When the receptacle is inserted into the header, the contacts of the first group are electrically connected to those of the second group. Lock lever engaging bodies are formed on both sides of the header. Lock levers are provided on both sides of the receptacle. Each lock lever has a lift pawl and a lock pawl. These pawls can engage with the upper and lower surfaces of the lock lever engaging body corresponding to the lock lever. They are arranged such that the lock lever engaging body is located between them when the receptacle is inserted in the header. The header and the receptacle are designed so that no surface contacts occur between the lock levers and the lock lever engaging bodies once the header has been inserted into the receptacle, with the lock pawls set in a closed state.
