Abstract

Considerable difficulty has been encountered in correctly positioning and insulating the tuning fork contact in a female type connector. The particular type connector for which this insulator has been designed is adapted to plug onto a small diameter pin which is surrounded by an egg-crate type guiding and grounding structure.

Insulator and Pin Guide

Considerable difficulty has been encountered in correctly positioning and insulating the tuning fork contact in a female type connector. The particular type connector for which this insulator has been designed is adapted to plug onto a small diameter pin which is surrounded by an egg-crate type guiding and grounding structure.

The insulator 10 is made of a good insulative material such as polycarbonate. Referring to the diagram, the insulator 10 is shown in position in a connector. The outer shield 12 of the connector has appropriate openings 14 so that barbs 16 on the insulator 10 can protrude therethrough to hold the insulator tightly in position. Also, the top of the insulator 10 has inwardly extending barbs 18 which connect over a shelf 20 on the tuning fork contact 22 22 prevent the tuning fork from being displaced out of position when it is pushed onto the pin. The insulator 10 has a specially formed cavity 24 therein which locates the tuning fork contact 22 in the proper position for receiving the mating pin 26. The bottom of the insulator has a bevelled opening which guides the pin directly into the tuning fork contact. It is important that the insulator have a certain amount of flexibility so that it can be easily inserted into the shield 12 of the connector. However, the insulator also must be sufficiently stiff so that it does not snap out of Position during use.
