an electrical connector for interconnecting a plurality of signals comprises an assembly of a plug and receptacle . the plug includes a housing member having a cavity at its forward end defined by a peripheral wall and a cavity wall , and a rear wall . the housing further includes contact receiving apertures extending between the cavity wall and the rear wall . an insert is locked in place in the forward cavity , the adjacent wall of the insert having standoff feet to define a gap between the cavity wall and insert wall . the insert has apertures in alignment with the apertures in the housing . the apertures within the insert include a shoulder facing the rear wall of the insert . a contact insertable into the apertures in the housing and insert has a lance which is locatable in the gap between the cavity wall and insert wall to lock the contact in place . the receptacle has a right - angled configuration having pins extending from a mounting face for interconnection to a printed circuit board . a second face is mountable to a bulkhead and has three rows of pins mounted in a cavity recessed from the second mounting face for interconnection to a matable plug having socket contacts . the contacts within the receptacle are disposed in three tiers , the contacts being bent around mandrels to form the right - angled bend . below the mandrels is a contact locating plate having contact receiving slots in line with the contacts . the upper and lower row of contacts are laterally aligned with each other and with a first contact receiving slot . the first slot has two widths , and has a rib extending down along the edges of the slot . when the contacts are placed in the slot , the ribs interferingly hold the contacts in place , the second row of terminals is also aligned with a contact receiving slot having ribs for interferingly locking the second row of terminals in place .
