Abstract
In making an electrical contact assembly of type having a louvered contact element, a terminal member is formed in first and second separable parts defining respective contact element retention surfaces. The contact element is formed into cylindrical configuration and is applied to the first terminal member part with one contact finger set thereof engaging the same, and is advanced into engagement with the retention surface thereof while common force is applied to the other contact finger set. The second terminal member part is then secured to the first part with the contact element engaging its retention surface. Assembly tools facilitate such common force application to the contact element.
Claims10
A method for making a contact assembly of type having a cylindrical terminal member and a contact element coaxially disposed relative to said terminal member and retained thereby, said contact element comprising a strip member with first and second contact finger sets extending respectively angularly outwardly of opposite surfaces of said strip member, said method comprising the steps of:
- a. forming said terminal member in first and second releasably engageable parts, forming a contact element retention surface on each such part and forming a contact element support surface on at least said first part;
- b. shaping said contact element into cyindrical configuration;
- c. applying such cylindrically shaped contact element to said terminal member first part with said first contact finger set in engagement with said support surface and, while applying common force to the fingers of said second contact finger set selected to be no greater than the force applied to said second contact finger set by a further terminal member engaging said first-mentioned terminal member in circuit connection use of said contact assembly, advancing said contact element strip member into engagement with said retention surface of said terminal member first part;
- and then
- d. engaging said terminal member second part with said terminal member first part in a manner providing engagement of said strip member with said retention surface of said terminal member second part.
A kit of parts for assembling an electrical terminal member, said kit comprising in first part a contact element comprising a strip member having first and second contact finger sets extending respectively angularly outwardly of opposite surfaces of said strip member, and in second part an assemby tool for applying said contact element to a terminal member having first and second separable parts defining contact element retention surfaces and a cylindrical contact element support surface therebetween, said assembly tool comprising a cylindrical body adapted to apply circumferential force to said contact element uniformly thereof, said circumferential force being substantially the same as that applied by a further terminal member when in mating engagement with said first mentioned terminal member, and said tool body further adapted to place said contact element in engagement with said retention surface of said terminal member first part.
