Abstract
An electrical connector includes an insulative housing, plural conductive terminals affixed to the insulative housing, and a shielding shell enclosing the insulative housing for forming a receiving room. The insulative housing includes a base portion and a tongue portion extending forwardly from the base portion. Each conductive terminal has a contacting portion disposed in the tongue portion. The shielding shell has a first wall, a second wall opposite to the first wall, and a pair of lateral walls connecting the first wall and the second wall. The thickness of the first wall is smaller than that of the lateral walls.
Claims18
An electrical connector comprising:
- an insulative housing comprising a base portion and a tongue portion extending forwardly from the base portion;
- a plurality of conductive terminals affixed to the insulative housing and each having a contacting portion disposed in the tongue portion;
- and
- a metallic shielding shell enclosing the insulative housing for forming a receiving room and having a first wall, a second wall opposite to the first wall, and a pair of lateral walls connecting the first wall and the second wall;
- wherein
- a thickness of the first wall is smaller than that of the lateral walls;
- and
- the base portion comprises a pair of resisting recesses located at a front end and a fixing slot communicating with the resisting recesses and extending laterally, the inner wall of the shielding shell comprises a pair of tubers resisting against the resisting recesses, the tongue portion comprises a stepped portion abutting with the base portion and a flat portion extending forwardly from the stepped portion, and the electrical connector further comprises a ground plate having a front covering portion exposed to the stepped portion and a rear covering portion attached to the fixing slot;
- and
- the insulative housing comprises a mounting portion located at a rear end of the base portion and having a fixing groove with an opening upwardly and a pair of resisting tubers located laterally besides the fixing groove in symmetry, the first wall comprises a pair of resisting protrusions extending obliquely in the receiving room, the resisting protrusions resist against the fixing groove and the resisting tubers, and the tubers resist against a front end of the rear covering portion extending to the fixing slot.

An electrical connector comprising:
- a tubular metallic shielding shell made by metal injection molding and forming therein a receiving room extending along a front-to-back direction by opposite top and bottom walls in a vertical direction perpendicular to the front-to-back direction, and two opposite lateral side walls, a thickness of the top wall being smaller than that of the side wall;
- a stationary tuber directly formed on an interior surface of the shielding shell by metal injection molding and extending into the receiving room, and a deflectable resisting protrusion directly formed on a rear end of the shielding shell by metal injection molding and located behind the tuber in the front-to-back direction;
- and
- a contact module including a plurality of conductive contacts fixed within an insulative housing, said housing including a base portion and a tongue portion extending forwardly from the base portion along the front-to-back direction, wherein
- said resisting protrusion is originally located at a first position to allow the contact module to be forwardly assembled into the receiving room from a rear side of the shielding shell until being confronted by the stationary tuber, and the resisting protrusion is successively deflected to a second position to prevent backward movement of the contact module with regard to the shielding shell so as to have the base portion of the housing sandwiched between the tuber and the resisting protrusion in the front-to-back direction for retaining the contact module within the shielding shell.

A method of making a low profile electrical connector, comprising steps of:
- providing a tuber metallic shielding shell by metal injection molding with opposite top and bottom walls in a vertical direction and a pair of opposite lateral side walls along a transverse direction perpendicular to said vertical direction to commonly form therein a receiving room extending along a front-to-back direction perpendicular to both said vertical direction and said transverse direction wherein a thickness of either the top wall or the bottom wall is smaller than those of the side walls, wherein said shielding shell unitarily forms an immoveable tuber extending into the receiving room, and a deflectable resisting protrusion located behind the tuber in the front-to-back direction;
- forming a contact module via insert molding with a plurality of conductive contacts fixed within an insulative housing, said housing including a base portion and a tongue portion forwardly extending from the base portion in the front-to-back direction;
- and
- forwardly assembling said contact module into the receiving room from a rear side of the shielding shell in said front-to-back direction until the base portion forwardly abuts against the tuber when the resisting protrusion is located at a first position, and successively deflecting the resisting protrusion toward a second position to prevent backward movement of the contact module with regard to the shielding shell in the front-to-back direction so as to have the base portion snugly sandwiched between the tuber and the resisting protrusion in the front-to-back direction.
