Abstract: An electrical connector assembly includes a high density plug connector 2 that is mated to a high density receptacle connector 4, each of which can be attached to wires 76. The plug connector includes male terminals 18 held in cavities 10 by resilient latches 12. The plug connector also includes a combination terminal guide and terminal position assurance member 26 which both guides and aligns male terminals 18 during mating and engages the resilient latches 12 to be sure that all of the terminals 18 are properly inserted in the plug connector housing 4. The male TPA guide member 26 is mounted on the plug connector housing mating face 6 and includes a front panel 28 with openings 30 for guiding the male terminals 18 during mating. Projections 32 extend from the panel 28 and function as terminal position assurance members.

Abstract: A seal (10) for use with an electrical connector includes an array of sealing units (20) each including a funnel-shaped section (22), an annular recess (24), an annular projection (26), and a box shaped recess (28). Adjacent to the sealing units are respective relaxation cores (30) for allowing the seal material to flow and fill in the relaxation cores thereby relieving the sealing units of stress and preventing tearing or cutting of the seal as the electrical contact (40) is inserted through the sealing unit (20). An interface angle (22c) is advantageously formed in a steep fashion so that the corners of the electrical contact (40) do not cut or tear the seal material.

Abstract: An electrical connector 6 includes a wire restraint arm 20 extending from one side of a connector body 8. Wires 2 connected to terminals 4 in this connector 6 are positioned on an exposed concave or V-shaped surface of this wire restraint arm 20. The wire restraint arm 20 provides both strain relief and isolates the terminals 4 from external vibration or motion of the wires 2. A central wire restraint section 32 is located between an inner lip 28 and an outer lip 30 that are wider and taller than the central section 32 to form a gap 26 at least partially surrounding the central section. A conventional wire tie 50 is held in this gap with the wire tie encircling both the wire bundle and the central wire restraint section 32. Ribs 40, 42, and 44 located on the central section 32 and the lips 28, 30 grip the wire insulation, and wires on the exterior of the wire bundle engage either the ribs or the cable tie. Wire bundles of different sizes can be accommodated.
