Abstract

An electrical cable connector comprising an insulating housing, a plurality of conductive contacts arranged on the insulating housing to be connected respectively with cables, and a resilient shell member attached to the insulating housing, wherein the resilient shell member includes a concealing portion for concealing a portion of the insulating housing on which the conductive contacts are arranged, a strip-shaped portion surrounding partially the insulating housing so as to cause an inner surface portion thereof to come into resilient contact with an outer surface portion of a mating connecting device, a pair of extended strip-shaped portions each extending to be bent from one of end portions of the strip-shaped portion so as to have a free end portion, and a pair of holding portions extending from the concealing portion for positioning respectively the extended strip-shaped portions from the outside thereof.

Claims

1. An electrical cable connector comprising;

an insulating housing provided to be fitted to a mate insulating housing of a mate electrical connector fixed to a parts-mounting surface of a circuit board,

a plurality of conductive contacts arranged on the insulating housing, each of which is provided with a cable connecting portion to be connected with a cable and a contact-connecting portion operative to be put in contact with a corresponding one of mate conductive contacts arranged on the mate insulating housing of the mate electrical connector to be connected to the circuit board, and

a resilient shell member attached to the insulating housing for engaging resiliently with the mate electrical connector when the electrical cable connector is coupled with the mate electrical connector, wherein

the resilient shell member includes a concealing portion for concealing a portion of the insulating housing on which the conductive contacts are arranged,

a strip-shaped portion linked with the concealing portion to surround partially the insulating housing for causing an inner surface portion thereof to come into resilient contact with an outer surface portion of the mate electrical connector,

a pair of extended strip-shaped portions each extending to be bent from one of end portions of the strip-shaped portion so as to have a free end portion and a pair of holding portions each extending from the concealing portion for positioning the extended strip-shaped portion from the outside of the same, and the strip-shaped portion and the extended strip-shaped portions constitute a spring member, and

the insulating housing accompanied with an inner shell member has a top board portion on which a plurality of openings in which contact-connecting portions of the plurality of conductive contacts are arranged respectively are arranged and a cable supporting portion which is reinforced with the inner shell member.

2. An electrical cable connector according to claim 1, wherein each of the holding portions has a constraining portion extending along an outer surface of the extended strip-shaped portion from the concealing portion and a covering portion elongating to be bent from the constraining portion for covering the extended strip-shaped portions.

3. An electrical cable connector according to claim 1, wherein the resilient shell member constitutes a single member with the strip-shaped portion which surrounds partially the insulating housing so that the end portions of the strip-shaped portion face each other with a predetermined space therebetween and the extended strip-shaped portions extend to be bent respectively from the end portions of the strip-shaped portion so as to be opposite to each other.

4. An electrical cable connector according to claim 3, wherein the cable connecting portion of each of the conductive contacts is exposed outward on the insulating housing in a space between the extended strip- shaped portions of the resilient shell member opposite to each other.

5. An electrical cable connector according to claim 1, wherein the resilient shell member constitutes first and second shell components attached to the insulating housing and each of the first and second shell components is provided with a part of the strip-shaped portion and the extended strip-shaped portion, so that the part of the strip-shaped portion of the first shell component and the part of the strip-shaped portion of the second shell component face each other with the insulating housing therebetween and the extended strip-shaped portion of the first shell component and the extended strip-shaped portion of the second shell component are opposite to each other with a predetermined space therebetween.

6. An electrical cable connector according to claim 5, wherein the extended strip-shaped portion of the first shell component and the extended strip-shaped portion of the second shell component are operative to cause the free end portions provided respectively on the extended strip-shaped portions to be opposite to each other.
