Abstract: A multi-pin electrical connector is adapted for surface mounting on a printed circuit board. The connector includes a header or housing having a plurality of pin-receiving through holes. A plurality of terminal pins are received in the holes of the header, with portions adapted for surface mounting on circuit traces on the printed circuit board. The terminal pins have spaced enlargements located on opposite sides of the header to retain the pins in the holes. The enlargements are spaced along the pins a distance greater than the thickness of the header about the holes whereby the pins can float in the holes to accommodate any non-uniform spacing between the header and the printed circuit board and ensure contact of the terminal pin portions with the circuit traces on the printed circuit board.

Abstract: A unitarily molded environmentally protective backshell is provided with a unitary ratcheted tie strap for strain relief connection of a cable to the backshell. The backshell comprises a base for receiving an electrical connector therein and a cover hingedly connected to the base for environmentally protecting the electrical connector therein. Resilient latches lockingly retain the cover to the base. The interengagement of the cover with the base prevents outward bowing of the base side walls. The ratcheted tie strap lockingly engages a deflectable ratchet trigger which also is unitary to the base. The trigger is angularly aligned to walls of a tie strap receiving aperture and is dimensioned to exert a biasing force against the tie strap thereby preventing loosening of the strain relief connection.
