Abstract
An electrical connector includes a dielectric housing and a number of contacts. One side of the dielectric housing defines a number of passageways for receiving the contacts. The contact includes a retention portion to secure the contact in the dielectric housing. The retention portion defines at least one through hole in the center. The housing is stamped and a corresponding number of projecting portions are extruded into the through holes after the contacts are inserted into the housing, thereby securing the contacts in the housing.
Claims11
An electrical connector for connecting an electrical device to a printed circuit board, comprising:
- a dielectric housing defining a plurality of passageways;
- a plurality of contacts received in the passageways, each of the contacts forming a retention portion for securing the contact in the housing, the retention portion defining at least one through holes in the center thereof;
- wherein the housing defines an outside the adjacent to the passageways, on which the housing is conveniently stamped on to extrude parts of the housing to form at least one projecting portion inside the passageway, the at least one projecting portion mating into the at least one through hole to secure the contact in the housing.
A method for making an electrical connector for connecting an electrical device to a printed circuit board, comprising:
- providing a dielectric housing having an outside face and a plurality of passageways arranged adjacent to the outside face, each of the passageways defining a mating surface generally parallel to the outside face;
- providing a plurality of contacts, each of the contact forming a retention portion, the retention portion defining a retention face for engaging with the mating surface and at least one through hole in the center of the retention face;
- inserting the contacts into the housing till the retention portion fits in the passageway;
- and
- stamping a line of dents on the outside face to extrude parts of the housing into the through holes to form projecting portions inside the passageways, wherein the projecting portions mate into the through holes, thereby securing of the contact in the housing.
An electrical connector for connecting an electrical device to a printed second cross-sectional dimension larger than the first cross-sectional dimension and the straight retention portion defining a third cross-sectional dimension smaller than the first dimension so that the contact is inserted into the corresponding passageway in a lengthwise direction defining by the passageway from the retention portion rather than the contact portion, the retention portion defining at least one through holes in a thickness direction thereof;
- wherein the housing is punched to form at least one projecting portion inside the passageway from one side of the passageway, the at least one projecting portion mating into the at least one through hole to secure the contact in the housing without movement along said lengthwise direction under a condition that the projection portion defines two opposite ends along said thickness direction, and the projecting portion is integrally formed with the housing at only one of said two opposite ends.
