Abstract: A connector that is configured to mate with different mating connectors by virtue of having different removably assembled interchangeable front housing portions includes a rear housing portion that includes a plurality of rear contacts. When the connector is to mate with a particular mating connector, a particular front housing portion of the connector that corresponds to the particular mating connector is selected from a plurality of available different front housing portions. The particular front housing portion is removably assembled to the rear housing portion, so that a plurality of front contacts of the particular front housing portion makes solderless physical and electrical contact with the plurality of rear contacts of the rear housing portion. The plurality of front contacts of the front housing portion are adapted to mate with corresponding contacts of the particular mating connector.

Abstract: In a specific embodiment, a connector 100 is disclosed. The connector 100 comprises an insulative housing 102 defining a rear opening 108 for receiving a plurality of electrical wires 110 and a front opening 106 and a circuit board 104 disposed in the housing 102 and comprising a mating section 112 for mating with a corresponding mating section of a mating connector. The mating section 112 protrudes outwardly from the front opening 106 and terminates at a front edge 118 disposed between opposing side edges 114,116 of the mating section 112. The connector 100 further comprises opposing side arms 128,130 extending forwardly from opposing lateral sides 124,126 of the front opening 106 along, adjacent and beyond corresponding side edges 114,116 of the mating section 112 with a maximum separation between each side edge 114,116 and the corresponding side arm 128,130 being sufficiently small so that when the connector 100 mates with a mating connector, no portion of the mating connector can be inserted between the side edge 114,116 and the corresponding side arm 128,130. Other exemplary embodiments are also disclosed.
