Abstract

The present disclosure discloses a plug connector including an insulating housing, a number of plug terminals and a cable. The insulating housing includes a width direction extending along a left-and-right direction. The plug terminals are retained by the insulating housing and arranged in two rows in the width direction of the insulative housing. The plug terminals of each row are arranged in an upper-and-lower direction and spaced away from each other in the upper-and-lower direction. Each plug terminal extends along a front-and-back direction. The cable includes a number of core wires correspondingly and electrically connected with the plug terminals. A connector assembly including the plug connector and the mated socket connector is also disclosed in the present disclosure.

First claim

a plurality of plug terminals retained by the insulating housing and arranged in two rows in the width direction of the insulative housing, the plug terminals of each row being arranged in an upper-and-lower direction and spaced away from each other in the upper-and-lower direction, each plug terminal extending along a front-and-back direction, wherein each plug terminal comprises a retaining arm fixed in the passage and a contacting arm extending forward from the retaining arm into the receiving space;
a cable comprising a plurality of core wires correspondingly and electrically connected with the plug terminals; and
a securing assembly which encloses the first insulating body, the plug terminals and the core wires, wherein the securing assembly comprises a left plate and a right plate respectively and oppositely located beside the first insulating body, the second insulating body and the third insulating body are exposed outside of the securing assembly, each of the left plate and the right plate comprises a plurality of receiving holes correspondingly engaging with the protrusions, each of the left plate and the right plate comprises a plastic piece and a metal piece, the metal piece comprises a base portion and a plurality of first fastening portions, the base portion is embedded in the plastic piece, the first fastening portions laterally and outwardly bend from the upper and lower ends of the base portion, the receiving holes are formed on the first fastening portions.

2. The plug connector according to claim 1 , wherein the second insulating body and the left plate are located at the same left side of the first insulating body, the second insulating body is positioned at the front of the left plate, the third insulating body and the right plate are located at the same right side of the first insulating body, the third insulating body is positioned at the front of the right plate.

3. The plug connector according to claim 1 , wherein the protrusions are non-circular protrusions and the receiving holes are non-circular holes, each of the left plate and the right plate comprises a first front end and a second back end, due to cooperation between the non-circular protrusions and the non-circular holes, the first front ends and the second back ends are capable of being installed on the first insulating body synchronously.

4. The plug connector according to claim 1 , wherein the protrusions are cylinders and the receiving holes are round holes, each of the left plate and the right plate comprises a first front end and a second back end, due to cooperation between the cylinders and the round holes, the first front ends are firstly installed on a front part of the first insulating body, the second back ends are capable of being rotated and then installed on a back part of the first insulating body subsequently.

5. The plug connector according to claim 1 , wherein the plastic piece comprises an inner side facing to the first insulating body, the inner side forms a plurality of grooves extending along the front-and-back direction, the core wires are accommodated in the grooves.

6. The plug connector according to claim 5 , wherein each groove comprises a shrink end, each plug terminal comprises a tail portion laterally bending from a rear end of the retaining arm, the first insulating body comprises a plurality of lumps which are symmetrically positioned on the left and right surfaces of the first insulating body, a front part of each core wire is fixed with the shrink end, a middle part of each core wire is snapped with the tail portion, a rear part of each core wire is fixed by the adjacent two lumps.

7. A plug connector, comprising:
an insulating housing which has a width direction extending along a left-and-right direction, wherein the insulating housing comprises a first insulating body, a second insulating body and a third insulating body, the first insulating body comprises two opposite vertically-extending surfaces, each vertically-extending surface includes a plurality of passages, the second insulating body and the third insulating body are arranged face to face along the left-and-right direction for defining a receiving space therebetween;
a plurality of plug terminals retained by the insulating housing and arranged in two rows in the width direction of the insulative housing, the plug terminals of each row being arranged in an upper-and-lower direction and spaced away from each other in the upper-and-lower direction, each plug terminal extending along a front-and-back direction, wherein each plug terminal comprises a retaining arm fixed in the passage and a contacting arm extending forward from the retaining arm into the receiving space;
a cable comprising a plurality of core wires correspondingly and electrically connected with the plug terminals;
a securing assembly which encloses the first insulating body, the plug terminals and the core wires; and
a butting assembly, an outer shell and a latch; wherein the butting assembly wraps the second insulating body and the third insulating body, the outer shell wraps the securing assembly, the latch pivotally connects to the butting assembly and is movable on the outer shell.

8. The plug connector according to claim 7 , further comprising a pin member; wherein the butting assembly comprises a flexible beam and a first securing portion at a free end of the flexible beam, the first securing portion comprises a first hole, the latch comprises a second securing portion, the second securing portion comprises a second hole, the pin member passes through the first hole and the second hole.

9. The plug connector according to claim 8 , further comprising a pair of blocks; wherein the blocks are spaced away from a top surface of the outer shell in the upper-and-lower direction, the outer shell supports the latch and the blocks press against the latch.

10. The plug connector according to claim 9 , wherein the blocks are spaced from each other in the left-and-right direction and an interspace is formed between the block, the latch comprises a neck portion which has a width smaller than the interspace for facilitating assembling the latch in the upper-and-lower direction.
