ABSTRACT:

FIELD OF THE INVENTION
The invention relates to electrical connectors that are intended for the coupling of paired devices arranged in mutually opposed directions.
BACKGROUND OF THE INVENTION
An example of a connector for coupling devices arranged in mutually opposed directions can be found in Patent Disclosure Hei 9 (1997)-199241. The disclosed electrical connector is designed to join two flexible circuit boards arranged at opposite sides of the connector and to form an electrical connection between the flexible circuit boards. In order to accept the flexible circuit boards, the contacts embedded in the insulating housing of the electrical connector have female type contacting sections. The contacts have press-in lugs for the purposes of being embedded in the insulating housing. The press-in lugs that extend virtually parallel to the female-type contacting sections fit into special cavities provided in the insulating housing, thus securing the contacts in the insulating housing.
Due to the fact that in the electrical connector described in the above mentioned patent disclosure, the press-in lugs are arranged virtually parallel to the female-type contacting sections, the contact receiving cavities provided in the insulating housing are relatively large, resulting in relatively large overall dimensions of the electrical connector.
SUMMARY OF THE INVENTION
An object of the present invention is to offer an electrical connector for electrical coupling between devices that are arranged in mutually opposed directions and that is characterized by easy assembly operations and small overall dimensions.
Accordingly, the present invention provides an electrical connector having contacts that are fabricated from a metal sheet by punch cutting and have primary and secondary female type contacting sections extending in one plane in opposite directions, with said contacts being secured in the cavities provided in an insulating housing by pressing, and by the fact that the above mentioned contacts have a base section located at the midpoint between said primary and secondary female contacting sections that is pressed in the above mentioned cavities.
An electrical connector is further provided having primary and secondary female type contacts which each have two mutually opposed arms. One arm from the pair of arms of said primary female type contacting section has a relatively lower resilience.
An electrical connector is further provided having primary and secondary female type contacts wherein the primary female type contacting section joins the base section only at the side of one arm. A pair of spring-loaded arms of the secondary female type contacting section is of a symmetrical configuration extending in the longitudinal direction. Each of the spring-loaded arms of the secondary female type contacting section extend toward its free end approximately in a straight line.
An electrical connector is further provided wherein the carrier strip holding the primary and secondary female type contacts is joined to the contacts at the front ends of spring-loaded arms of the secondary female type contacting section, and this connection is cut off after said contacts are secured in the insulating housing.
An electrical connector is further provided having primary and secondary female type contacts mounted in cavities in an insulating housing, the housing having a receiving slot which intersects the cavities. The insulating housing has a through opening extending in the vertical direction at the location of front ends of arms of the secondary female type contacting section. Edges of said through openings have slanted surfaces.
