Abstract
Various methods and techniques for making barrel terminals are disclosed, all of which are based upon the initial formation of the terminal contactor strips as an integral flat sheet metal blank produced by a conventional stamping operation. The contactor strips may thus be maintained in a predetermined relationship with each other and manipulated as a unit through successive assembly steps well adapted to be performed by automated tooling. Several contactor strip blank configurations are disclosed, together with assembly methods for forming and assembling the blanks into completed barrel terminals.
Claims11
The method of making a barrel terminal comprising the steps of:
- A. forming a flat sheet metal blank with a plurality of elongate strips integrally connected in spaced parallel relationship to each other by at least one connecting web extending transversely of said strips adjacent one end of said strips,
- B. positioning said strips within a hollow cylindrical sleeve with said strips lying against the inner surface of said sleeve in parallel relationship to the axis of said sleeve and with end portions of said strips projecting axially from at least one end of said sleeve,
- C. angularly displacing the end portions of said strips at said one end of said sleeve relative to said sleeve about the sleeve axis while holding the strips at the opposite end of said sleeve in fixed relationship to said sleeve, and
- D. fixedly securing the angularly displaced end portions to said sleeve at said one end thereof.
A barrel terminal comprising a hollow cylindrical sleeve, a plurality of elongate contactor strips located within said sleeve and extending in straight line paths between respective first circumferential locations on said sleeve adjacent a first end of said sleeve to respective corresponding second circumferential locations on said sleeve adjacent the opposite end of said sleeve, each first circumferential location on said sleeve bing angularly displaced about the axis of said sleeve from its corresponding second circumferential location, first means fixedly securing said strips in mechanical and electrical contact with said sleeve at said first locations, and second means fixedly securing said strips in mechanical and electrical contact with said sleeve at said second locations, at least one of said first and said second means comprising reversly bent tab portions integrally connected to said strips and lying in face-to-face engagement with the exterior of said sleeve at circumferentially spaced locations, at one end of said sleeve and an annular collar fixedly clamping said tab portions against the exterior of said sleeve.
