Abstract: A connector assembly includes first and second connectors. Each connector includes a plurality of terminals A1 through An, n is an integer≥2, sequentially arranged in a row. The connector assembly also includes a flat cable that includes a plurality of electrical conductors electrically connecting the terminals of the first and second connectors. For each i from 1 to n, terminal Ai of the first connector is electrically connected, via a different electrical conductor of the cable, to the terminal Ai of the second connector. The cable includes a bend greater than about 150° around at least two fold lines that extend across the entire width of the cable. Each of the first and second connectors is configured to mate with the same mating connector, such that when each of the first and second connectors mates with the same mating connector in a same plan view, the An terminals are both either on a left or a right side of the A1 terminals.

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.

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.

Abstract: An electrically conductive contact of an electrical connector includes an L-shaped main body comprising first and second legs connected at a junction. The first leg is configured to make physical and electrical contact with a first electric conductor. The contact includes an elongated resiliently flexible arm extending from an end of the second leg toward the junction and making an acute angle with the second leg at the end of the second leg. The flexible arm is configured to make solderless contact with a second electric conductor by pressing against the second electric conductor and resiliently flexing toward the second leg.
