Abstract
An electrical connector includes an insulative housing having a first insulator integrally formed with the contacts via an insert-molding process, and a second insulator, i.e., the cover, overmolded upon the first insulator wherein an internal cavity is formed within the housing and between the first insulator and the second insulator in the transverse direction, through which a sliding block presses the first insulator in position in the transverse direction during overmolding the second insulator.
Claims11
An electrical connector comprising:
- a contact module including a plurality of contacts integrally formed within an inner insulator via an insert-molding process, said contacts being arranged in one row along a longitudinal direction, each of said contacts including an upper contacting section, a lower tail section and a middle retaining section therebetween in a vertical direction perpendicular to the longitudinal direction wherein the contacting section is planar and immovable, and directly exposed to an exterior outside of the electrical connector in a transverse direction perpendicular to both the longitudinal direction and the vertical direction;
- and
- an outer insulator applied upon the contact module via a single overmolding process to retain the contact module circumferentially along all the vertical direction, the longitudinal direction and the transverse direction, except a bottom end of the contact module which is adapted to face downward, in the vertical direction, toward a printed circuit board on which the electrical connector is adapted to be mounted, and the contacting sections which are exposed to said exterior in the transverse direction;
- wherein
- an internal cavity is formed between the inner insulator and the outer insulator in the transverse direction and downward faces toward said exterior in the vertical direction to be adapted to face downwardly toward the printed circuit board in the vertical direction;
- wherein
- said internal cavity is configured to be adapted to receive, during said overmolding process, a metallic sliding block, which is not a part of the electrical connector while being adapted to press the inner insulator in said transverse direction;
- wherein
- the outer insulator is inherently adhered and attached upon the inner insulator due to the overmolding process.

A method of making an electrical connector, comprising steps of:
- providing a contact module with a plurality of contacts integrally formed within an inner insulator via an insert-molding process, wherein said contacts are arranged in one row along a longitudinal direction, each of said contacts includes an upper contacting section, a lower tail section and a middle retaining section therebetween in a vertical direction perpendicular to said longitudinal direction, and the contacting section is exposed toward an exterior in a transverse direction perpendicular to both longitudinal direction and the vertical direction;
- applying an outer insulator upon the inner insulator via an overmolding process to enclose said contact module to form the complete electrical connector wherein the outer insulator forms two opposite mating surfaces in the transverse direction and said contacting sections of all the contacts are exposed to the exterior on only one of said two opposite mating surfaces;
- and forming an internal cavity by removing a metallic sliding block from the connector after the overmolding process;
- wherein
- said internal cavity communicates with the exterior only downwardly in the vertical direction, and the inner insulator is located between the internal cavity and said only one of said two opposite mating surfaces in the transverse direction;
- wherein
- the outer insulator is inherently adhered and attached upon the inner insulator due to the overmolding process.
