Abstract

This article describes a socket for small, cylindrical components (such as light-emitting diodes or phototransistors) not equipped with wire leads. Referring to the drawing, component 10 represents a common photosensitive device. The component has a cylindrical stem 12 (which is the cathode), a photoactive region 16, and a flange 14 which serves as the anode. The socket is an extension of a coaxial cable having a core conductor 18 and a conductor 20 separated by an insulating layer 22. The cable has an outer sheath 24 of insulation. The socket includes an annular conductor 26 which is crimped and perhaps soldered to core conductor 18 at a region 28. The inside diameter of the uncrimped region of conductor 26 is a tight fit with stem 12 of component 10.

Coaxial Socket for Lead-Free Components

This article describes a socket for small, cylindrical components (such as light- emitting diodes or phototransistors) not equipped with wire leads. Referring to the drawing, component 10 represents a common photosensitive device. The component has a cylindrical stem 12 (which is the cathode), a photoactive region 16, and a flange 14 which serves as the anode. The socket is an extension of a coaxial cable having a core conductor 18 and a conductor 20 separated by an insulating layer 22. The cable has an outer sheath 24 of insulation. The socket includes an annular conductor 26 which is crimped and perhaps soldered to core conductor 18 at a region 28. The inside diameter of the uncrimped region of conductor 26 is a tight fit with stem 12 of component 10. The cable's outer conductor 20 is flared at region 30 to receive the inner end of a second socket conductor 32. Conductor 32 may support a mounting ring 34 which provides a seat for flange 14. The spacing between the conductors 26 and 32 of the socket is maintained by an intervening layer 36 of insulating material.
