US Patent 7500887 Connector and method of assembling it

A connector housing assembly (10) is formed by assembling a first housing (11) and a second housing (40) individually formed by molds that are opened in forward and backward directions, and an accommodation space (70) for accommodating a retainer (60) is defined between the first housing (11) and the second housing (40). It is sufficient for the molds for forming the connector housing assembly (10) to include only the molds that are opened in forward and backward directions to form the two housings (11, 40), and a mold that is opened in a direction normal to forward and backward directions is not necessary. Thus, space required for the molds for forming the connector housing assembly (10) can be small.
