Patent number: 5167531Abstract: A rightangle board mount electrical connector of high contact density includes a diecast metal housing having a front wall and rearwardly projecting side walls. The front wall has upper and lower through openings therein each receiving a drawn metal shell which in turn receives an insulating header having cavities containing mating portions of electrical terminals. Each terminal has projecting obliquely and rearwardly from the respective header a terminal leg terminating in a soldering tail. The terminal legs are so dimensioned that the solder tails are arranged in four rows for insertion through holes in a spacer plate. A shield can be inserted downwardly between the housing side walls for retention in the housing. A downwardly inclined rearwall of the shield covers the terminal legs for complete shielding of the terminals. In use of the connector the housing is grounded to a circuit board in which the connector is mounted and the shield is similarly grounded.Type: GrantFiled: March 18, 1992Date of Patent: December 1, 1992Assignee: AMP IncorporatedInventors: John L.

Patent number: 5123859Abstract: A stackable connector (20) formed by positioning connector housings (22,24) back-to-back and securing them together with terminating covers (26,28). Opposing terminating covers (26,28) have leg means (86,88,90,92) that complement leg means on the other terminating cover to substantially fill apertures (52). Either a short segment of cable or conductors of a cable are terminated on corresponding ones of contacts in the two housings (22,24). The terminating covers (26,28) are secured to housings (22,24) in a pretermination position in which corners (98,100) of leg means (86,88,90,92) engage side walls (126) of apertures (52) in a first interference fit. As termination of the conductors is completed, leg means (86,88,90,92) of terminating cover (86) enter apertures (104,106,108,110) on terminating cover (28) and engage a protrusion (112,114,116,118) in a second interference fit.Type: GrantFiled: August 22, 1991Date of Patent: June 23, 1992Assignee: AMP IncorporatedInventors: Wayne S.

Patent number: 4960390Abstract: There is disclosed a connector (20) for terminating to a plurality of conductors (64). The connector includes a housing (24) having conductor terminating contacts (26) secured therein and defining an axis. First and second terminating covers (28,30) are adapted to be secured to the housing (24) from opposed directions, transverse to the axis of the contacts in a terminating position in which the conductors (64) are terminated to respective ones of the contacts (26), with the terminated conductors extending rearwardly of the housing (24) substantially parallel to the axis. A strain relief member (22) adapted to be secured to the housing (24) includes a transverse member (126) and cover retention means (138,140). The transverse member (126) intersects the rearwardly extending conductors (64) when the strain relief member (22) is secured to a housing (24) terminated to conductors (64) and causes the conductors to extend transverse to the contact axis to pass beyond the transverse member (126).Type: GrantFiled: January 29, 1990Date of Patent: October 2, 1990Assignee: AMP IncorporatedInventors: Wayne S.
