Abstract

Abstract A one-piece metal cable guide member for guiding an undersize cable into a shielded plug housing which has a cable supporting base (18), cable locators (24, 25) upstanding from the base (18) in spaced apart relation to locate between them an insulated conductor row (42) and cable sheath (41) and shielding flanges (26) upstanding from the base (18) to extend along a rear end between opposite side edges of the base (18) and the cable locators (24, 25). The cable guide member is inserted front end leading into the mouth (31) of the plug cavity guiding the conductors (41) into pathways communicating with the mouth with the shielding flanges (26) completely closing and thereby shielding the mouth (31) on each side of the cable. The cable shield (43) is pressed against the base (18) which connects directly with flaps (36) extending into the mouth from the housing shield (35).

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 234 words
An electrical plug assembly comprising an insulated housing having a cable-receiving mouth opening to a rear end of the housing and communicating internally of the housing with a row of conductor-receiving pathways extending to a front end of the housing in alignment with respective terminals, a shield member of conductive material extending around the housing forwardly from the rear end to provide a substantially continuous shield around the mouth; a one-piece cable guide member of conductive material having front and rear ends between which extends a cable supporting base, cable locators upstanding from the base in spaced apart relation to locate between them an insulated conductor row and cable sheath extending between front and rear ends of the cable guide member and, shielding flanges upstanding from the base to extend along the rear end between opposite side edges of the base and the cable locators; whereby on loading a shielded cable into the guide member with an outer insulation sheath stripped cut back from a front end to expose the row of insulated conductors free of the shield with the cable located between the cable locators, the cable guide member can be inserted, front end leading, into the mouth, drawer fashion, as a sliding fit, guiding the conductors into respective ones of said pathways with the shield flanges completely closing the mouth on each side of the cable and electrically connected to the shield.
Claim 2
Dependent Claim 234 words
An electrical plug assembly comprising an insulated housing having a cable-receiving mouth opening to a rear end of the housing and communicating internally of the housing with a row of conductor-receiving pathways extending to a front end of the housing in alignment with respective terminals, a shield member of conductive material extending around the housing forwardly from the rear end to provide a substantially continuous shield around the mouth; a one-piece cable guide member of conductive material having front and rear ends between which extends a cable supporting base, cable locators upstanding from the base in spaced apart relation to locate between them an insulated conductor row and cable sheath extending between front and rear ends of the cable guide member and, shielding flanges upstanding from the base to extend along the rear end between opposite side edges of the base and the cable locators; whereby on loading a shielded cable into the guide member with an outer insulation sheath stripped cut back from a front end to expose the row of insulated conductors free of the shield with the cable located between the cable locators, the cable guide member can be inserted, front end leading, into the mouth, drawer fashion, as a sliding fit, guiding the conductors into respective ones of said pathways with the shield flanges completely closing the mouth on each side of the cable and electrically connected to the shield.
Claim 3
Dependent Claim 21 words
An electrical plug assembly according to claim 1 in which the cable guide member is stamped and formed from sheet metal.
Claim 4
Dependent Claim 47 words
An electrical plug assembly according to claim 1 in which the cable guide member is provided with means upstanding from the general plane of the base to engage the leading end of the cable sheath to limit forward movement of the cable when loaded onto the base.
Claim 5
Dependent Claim 38 words
An electrical plug assembly according to claim 3 in which the base is stepped up towards the front end to provide a platform supporting the insulated conductor array centrally of the cable, the step providing the limiting means.
Claim 6
Dependent Claim 51 words
An electrical plug assembly according to claim 4 in which the cable locators comprise a first pair of flanges upstanding from the platform for receiving the insulated conductor array between them and a second pair of flanges upstanding from the base adjacent the rear for receiving the cable sheath between them.
Claim 7
Dependent Claim 33 words
An electrical plug assembly according to claim 5 in which the sheath locators comprise a pair of resilient sheath clamping arms extending forwardly cantilever fashion from root ends integral with the shield flanges.
Claim 8
Dependent Claim 61 words
An electrical plug assembly according to claim 1 in which the shield member includes resilient flaps extend forwardly into the mouth cantilever fashion across a floor of the housing and are engageable with the base of the cable guide member when the cable guide member is inserted into the housing to effect the electrical connection to the flanges through the base.
Claim 9
Dependent Claim 40 words
An electrical plug assembly according to claim 7 in which a locking protuberance extends downwardly from the base of the cable guide member for engagement with forward free ends of the flaps to lock the shield member in the housing.
Claim 10
Dependent Claim 57 words
An electrical plug assembly according to claim 7 in which a strain relief member is depressable into the mouth into engagement with the cable sheath with the cable shield sandwiched between the base of the cable guide member and the flaps thereby to press the cable shield, the cable guide member and the flaps against each other.
Claim 11
Dependent Claim 99 words
A cable guide member for an electrical plug assembly according to claim 1 which cable guide member is stamped and formed from a single piece of sheet metal and has front and rear ends between which extends a cable supporting base, cable locators upstanding from the base in spaced apart relation to located between them an insulated conductor row and sheath of a cable extending between front and rear ends of the cable guide member and, shielding flanges upstanding from the base to extend along the rear end between opposite side edges of the base and the cable locators.
Claim 12
Dependent Claim 38 words
A cable guide member according to claim 10 in which the base is stepped up towards the front end to provide a platform supporting the insulated conductor array centrally of the cable, the step providing the limiting means.
Claim 13
Dependent Claim 50 words
A cable guide member according to claim 11 in which the cable locators comprise a first pair of flanges upstanding from the platform for receiving the insulated conductor array between them and second pair of flanges upstanding from the base adjacent the rear for receiving the cable sheath between them.
Claim 14
Dependent Claim 33 words
A cable guide member according to claim 11 in which the sheath locators comprise a pair of resilient sheath clamping arms extending forwardly cantilever fashion from root ends integral with the shield flanges.
