Abstract

A connector including a plastic body, a steel case housing a front part of the plastic body, an insertion body assembled to a rear end of the plastic body with insertion terminals on the plastic body separately located in terminal slots on the insertion body. Two cables including many conductors are symmetrically connected to upper and lower sides of the insertion body with bared front ends of the conductors separately located in the terminal slots on the insertion terminals. Two covers with forward projected pressing ribs are firmly covered onto the cables with the pressing ribs located in the terminal slots of the insertion body above the bared front ends of the conductors and the insertion terminals to tightly press them together. The covers and their pressing ribs are fixedly connected to the insertion body and the terminal slots by means of radio heating, so that each bared front end of the conductor is located in one terminal slot to tightly contact with only one insertion terminal without the risk of short circuit.

Claims

1. An electrical connector comprising a plastic body, a steel case housing a front part of said plastic body, an insertion body assembled to a rear end of said plastic body, two covers, and two interconnecting cables symmetrically connected to upper and lower sides of said insertion body at a rear portion thereof;

said plastic body being provided at a front surface with upper and lower rows of alternately arranged insertion terminals and at two lateral sides with two rearward extended side walls that are formed at respective inner surface with a guiding rail having a retaining hole provided at a predetermined suitable position, and two vertically extended insertion slots being symmetrically provided at inner surfaces of said two side walls at the respective predetermined positions;

said insertion body being provided at top and bottom front surfaces with two rows of terminal slots corresponding to said insertion terminals on said plastic body and at two lateral sides of said insertion body with protrusions corresponding to said retaining holes in said guiding rails of said plastic body;

said insertion body also being provided between adjacent rear ends of said terminal slots with partitioning ribs, two transverse receiving recesses being separately provided on upper and lower surfaces of said insertion body to divide said partitioning ribs into discontinued front and rear sections;

each of said interconnecting cables including a plurality of conductors that are arranged corresponding to said insertion terminals and fixed in place by clamping said conductors between two transversely extended clamping pieces, such that bared front ends of said conductors forward project from a front side of said clamping pieces, and said clamping pieces being suitable for positioned in said receiving recesses of said insertion body with said bared front ends of said conductors located in corresponding terminal slots on rear ends of said insertion terminals in the same said terminal slots; and

said two covers being symmetrically formed and having at each lateral end a centered projection corresponding to said vertical insertion slot in said plastic body and each of said covers having a front edge including a plurality of forward projected pressing ribs corresponding to said terminal slots on said insertion body;

said insertion body being inserted into said plastic body with rear ends of said insertion terminals located in said terminal slots between front sections of two adjacent partitioning ribs, said clamping pieces with conductors clamped therebetween being set in said receiving recesses on said insertion body with said conductors separately located between two adjacent partitioning ribs and said bared front ends of said conductors located on and contacting with rear ends of said insertion terminals correspondingly located in said terminal slots, said two covers being located onto said clamping pieces with said lateral projections aligning with said vertical insertion slots on said plastic body and being received said recesses of said insertion body and said pressing ribs forward projected from said covers located in said terminal slots above said bared fronts of said conductors and said insertion terminals to tightly press said conductors together, and rear edges of said covers being firmly connected to rear sections of said partitioning ribs and said pressing ribs to said front sections of said partitioning ribs at two sides of said terminal slots by means of radio heating;

whereby each bared front end of said conductors is located in one said terminal slot to tightly contact with only one said insertion terminal to free said connector from short circuits at contact points.
