Abstract An electrical socket contact forms an electrical contact portion in a compact size to which a mating contact is inserted and connected. A concave portion is formed opposite to a resilient tongue in the transverse direction of a side end of the short rectangularly tubular electrical contact portion provided the resilient tongue for electrical contact within the electrical contact portion. A folded portion extending from a side free end of the electrical contact portion is also provided which engages the concave portion.

Claim 1
Independent Claim
92 words
An electrical socket contact comprising: a short rectangularly tubular electrical contact portion including a top-wall portion having a side-end portion, and a side-wall portion having a free-end portion abutting said side-end portion of said top-wall portion; a resilient tongue for electrical contact provided within said electrical contact portion; a concave portion formed opposite to said resilient tongue in the transverse direction of said side-end portion of said top-wall portion; and a folded portion extending from said free-end portion of said side-wall portion of said electrical contact portion, and engaging said concave portion.
Claim 2
Dependent Claim
92 words
An electrical socket contact comprising: a short rectangularly tubular electrical contact portion including a top-wall portion having a side-end portion, and a side-wall portion having a free-end portion abutting said side-end portion of said top-wall portion; a resilient tongue for electrical contact provided within said electrical contact portion; a concave portion formed opposite to said resilient tongue in the transverse direction of said side-end portion of said top-wall portion; and a folded portion extending from said free-end portion of said side-wall portion of said electrical contact portion, and engaging said concave portion.
Claim 3
Dependent Claim
116 words
An electrical socket contact comprising: a short rectangularly tubular electrical contact portion formed of electrically conductive materials, including a top-wall portion having a side-end portion, a bottom-wall portion and two side-wall portions, wherein one of said two side-wall portions has a free-end portion abutting said side-end portion of said top-wall portion; a resilient tongue for electrical contact provided within said electrical contact portion; a concave portion formed opposite to said resilient tongue in the transverse direction of said side-end portion of said top-wall portion; and a folded portion, corresponding to said concave portion, extending in the transverse direction of said free-end portion of said side-wall portion of said electrical contact portion and engaging said concave portion.
