Abstract

Insulative base 1 drawing A, holds and electrically shields an assembly of pin-type connector contacts 2. The latter engage in plug-in connections with corresponding socket type contacts 3. Orifices 4 in base receive keyed ends 5 of contacts 2 in snug force fits. This orients the laterally extended contact-making tips 6 of contacts 2 at specific angles relative to receiving grooves 7 of respective contacts 3. Consequently, contacts 2 are torsionally stressed, drawings B and C, is rotational direction 8 in the process of making connection with contacts 3. Longitudinal stem sections 9 of contacts 2 are made torsionally resilient so that the torsional stress of engagement operates to secure contact pressure between tips 6 of contacts 2 and inner surfaces 10 of grooves 7 of respective contacts 3.

Base for Holding Torque Pin Connectors

Insulative base 1 drawing A, holds and electrically shields an assembly of pin-type connector contacts 2. The latter engage in plug-in connections with corresponding socket type contacts 3. Orifices 4 in base receive keyed ends 5 of contacts 2 in snug force fits. This orients the laterally extended contact-making tips 6 of contacts 2 at specific angles relative to receiving grooves 7 of respective contacts 3. Consequently, contacts 2 are torsionally stressed, drawings B and C, is rotational direction 8 in the process of making connection with contacts 3. Longitudinal stem sections 9 of contacts 2 are made torsionally resilient so that the torsional stress of engagement operates to secure contact pressure between tips 6 of contacts 2 and inner surfaces 10 of grooves 7 of respective contacts 3.

Contacts 2 are mounted in close proximity in compartments 11 of base 1. Hence shielding is usually required between adjacent tips 6 to prevent signal cross talk between adjacent contacts 2. For this purpose, insulative extensions 12 of base 1, which form compartments 11, are lined with shield layer 14 of conductive material. This layer forms a noise shield extending continuously over edges 15 of extensions 12. Within all but a few of compartments 11, layer 14 provides a partial enclosure surrounding essentially only tips 6 of respective contacts 2 and the complete receiving contact 3.

In the few excepted compartments 11, layer 14 is extended to orifices 4 thus contacting ends 5 of contacts 2 in such compartments and through respective contacts 3 making contact with an internal shielding layer 17 in multilayer printed circuit board 18. The latter holds in contacts 3 through connecting apertures 19. Thus, integrated circuit chips the like can be mounted on base 1, attached by solder to ends of c...
