Abstract
Abstract A contact for a connector, which includes two opposed contact elements for receiving therebetween a male contact of a mating connector. Each the contact element is provided with one or more protrusions on an opposed surface for embracing the male contact. Protrusions of the two opposed contact elements extend to that portions of the opposed contact elements which are devoid of the protrusions so as to overlap each other before the male contact is inserted between the contact elements. With this arrangement, even if the male contact is very thin, pressing force required to securely pressing the male contact by the contact elements is certainly obtained. The contact and the male contact are securely contacted without any torsional force and other forces which would otherwise be caused on these contacts.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
A contact for a connector, said contact including two opposed contact elements for receiving a male contact of a mating connector inserted therebetween in a direction of insertion; each said contact element having a width and being provided with at least one protrusions for embracing said male contact, said protrusion of each of said two opposed contact elements extending to portions of said respective opposing contact elements devoid of said protrusions to overlap each other before said male contact is inserted therebetween, the sum of the total number of said protrusions on both said elements combined being at least three; and each of said protrusions being symmetrically arranged across said widths of said opposed elements on a perpendicular axis to said direction of insertion.
Claim 2
Dependent Claim
124 words
A contact for a connector, said contact including two opposed contact elements for receiving a male contact of a mating connector inserted therebetween in a direction of insertion; each said contact element having a width and being provided with at least one protrusions for embracing said male contact, said protrusion of each of said two opposed contact elements extending to portions of said respective opposing contact elements devoid of said protrusions to overlap each other before said male contact is inserted therebetween, the sum of the total number of said protrusions on both said elements combined being at least three; and each of said protrusions being symmetrically arranged across said widths of said opposed elements on a perpendicular axis to said direction of insertion.
Claim 3
Dependent Claim
32 words
A contact for a connector as set forth in claim 1, wherein each said protrusion has a U-shaped cross-section in a plane substantially perpendicular to an inserting direction of said male contact.
Claim 4
Dependent Claim
34 words
A contact for a connector as set forth in claim 1, wherein each said protrusion is formed by bending the contact element along lines substantially perpendicular to an inserting direction of said male contact.
Claim 5
Dependent Claim
42 words
A contact for a connector as set forth in claim 1, wherein said protrusions are substantially aligned with each other in a direction substantially perpendicular to an inserting direction of said male contact on the opposed surface of each said contact element.
Claim 6
Dependent Claim
31 words
A contact for a connector as set forth in claim 1, wherein sum of numbers of said protrusions of said two opposed contact elements is an odd number more than three.
Claim 7
Dependent Claim
16 words
The connector defined in claim 1 wherein each of said protrusions is symmetrical about an axis.
Claim 8
Dependent Claim
18 words
The connector defined in claim 6 wherein said axes are perpendicular to said width of said connector elements.
