Abstract
Abstract An electrical split sleeve socket contact (10) is disclosed including a plurality of tines (26) formed by slots (30) axially extending from the front of a contact sleeve (12) in which an increased contact pressure is achieved by an axially extending central rib (44) and inwardly crimped sides (46) of each of the contact tines (26) to provide three line contact of each tine with the pin contact (22) and increase the flexural rigidity of each of the tines (26) (FIG. 3).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
184 words
In combination with a split sleeve socket contact of the type adapted to be mated with a pin contact and including a generally cylindrical contact sleeve being formed with a series of axially extending slots extending in from a front end of the contact sleeve to form a corresponding series of tines, and a surrounding hood sleeve, with the entire length of each of said tines being spaced from the inside of said hood sleeve, both with and without said pin contact inserted to enable radial separation of each tine upon insertion of a pin contact, the improvement wherein each of said tines is configured with an inwardly protruding axial rib extending to the front end thereof and a pair of radially inwardly crimped sides establishing three lines of contact with said pin contact upon insertion thereof; said tines being configured so that all portions thereof are moved radially outward upon insertion of said pin contact while maintaining said three lines of contact therewith, whereby said flexural rigidity of said tines and contact pressure is improved by said rib and said three line contact.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
55 words
The split sleeve socket contact according to claim 1 wherein each of said radially inwardly crimped sides extends rearwardly of said contact sleeve and wherein said contact sleeve is further formed with a transverse relief slot located at the end of each of said slots to thereby accomodate radially inward crimping of said tine sides.
Claim 4
Dependent Claim
29 words
The split sleeve socket contact according to claim 1 wherein said radially inwardly crimped sides are formed at a localized region at the front end of said contact sleeve.
Claim 5
Dependent Claim
30 words
The split sleeve socket contact according to claim 1 wherein a pair of axially extending slots are formed in said contact sleeve to form a corresponding pair of opposed tines.
Claim 6
Dependent Claim
48 words
The split sleeve socket contact according to claim 1 wherein said contact sleeve is formed with a generally cylindrical body section to the rear of said tines, said body section telescopically receiving said hood thereover, and said hood being crimped to said body section of said contact sleeve.
