Abstract
Abstract An improved shielded and insulated electrical connector for terminating shielded multiconductor cable is formed by a pair of mating metal shield members which engage a peripheral metal shell means on a standard connector and enclose the rear conductor exiting portion thereof. The shield members each include embossed strengthening means as well as interengaging side walls to completely enclose the rear of an electrical connector. At least one shield member is provided with at least one overmolding pressure relief means which opens at a predetermined pressure and allows a limited amount of overmolding insulating material to enter the cavity defined by the shield members while equalizing the inner and outer shield member pressures. The shield members also include gripping means which allow overmolding insulative material to enter and harden thereby becoming fixedly attached to the shield members to prevent withdrawal due to shrinking as the overmold insulative material cools. At least one of the shield members is preferably provided with continuity lances which positively engage the metal shell of the connector to assure good electrical contact therewith. The shield members include latching means and they are held together by a crimp ring which secures the cable shield thereto.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
155 words
A shielded electrical connector comprising an insulative housing having a front mating face, a rear conductor receiving face, and a plurality of terminals mounted therein, metal shell means mounted on the periphery of said housing between said faces, said shell means having an aperture therethrough, a pair of stamped and formed metal shields enclosing the rear conductor receiving face of the housing and a cavity extending rearward therefrom, said shields each having hooked tines which engage said shell means proximate said aperture as said shields are rotated about said tines and into engagement to form said cavity, at least one of said shields having protuberance means thereon which engages said shell means in interference so as to oppose rotation of said shields, by resilient engagement between said protuberance means and said shell means, thereby forming a stored energy preload condition assuring electrical continuity between said shell means and said shields when said shields are engaged.
Claim 2
Dependent Claim
155 words
A shielded electrical connector comprising an insulative housing having a front mating face, a rear conductor receiving face, and a plurality of terminals mounted therein, metal shell means mounted on the periphery of said housing between said faces, said shell means having an aperture therethrough, a pair of stamped and formed metal shields enclosing the rear conductor receiving face of the housing and a cavity extending rearward therefrom, said shields each having hooked tines which engage said shell means proximate said aperture as said shields are rotated about said tines and into engagement to form said cavity, at least one of said shields having protuberance means thereon which engages said shell means in interference so as to oppose rotation of said shields, by resilient engagement between said protuberance means and said shell means, thereby forming a stored energy preload condition assuring electrical continuity between said shell means and said shields when said shields are engaged.
Claim 3
Dependent Claim
23 words
A connector as in claim 1 wherein said aperture is profiled with recesses along the marginal edge thereof, said tines engaging said recesses.
Claim 4
Dependent Claim
18 words
A connector as in claim 1 wherein said protuberance means comprises at least one protuberance on each shield.
Claim 5
Dependent Claim
18 words
A connector as in claim 3 wherein said at least one protuberance lies between a pair of tines.
Claim 6
Dependent Claim
59 words
A connector as in claim 1 wherein said aperture is profiled with recesses along the marginal edges thereof, said tines engaging said recesses, said protuberance means comprising at least one protuberance on each shield, said at least one protuberance lying between a pair of tines and engaging said shell means proximate said aperture between a respective pair of recesses.
Claim 7
Dependent Claim
161 words
A shielded electrical connector comprising an insulative housing having a front mating face, a rear conductor receiving face, and a plurality of terminals mounted therein, metal shell means mounted on the periphery of said housing between said faces, said shell means having an aperture therethrough, said aperture being profiled with recesses along the marginal edges thereof, a pair of stamped and formed metal shields enclosing the rear conductor receiving face of the housing and a cavity extending rearward therefrom, said shields each having hooked tines which are received in respective ones of said recesses and engage said shell means as said shields are rotated about said tines and into engagement to form said cavity, each said shield engaging said shell means in resilient interference between each pair of recesses when said shields are engaged so as to oppose rotation of said shields, thus forming a stored energy preload condition, whereby electrical continuity between the shell means and the shields is assured.
Claim 8
Dependent Claim
161 words
A shielded electrical connector comprising an insulative housing having a front mating face, a rear conductor receiving face, and a plurality of terminals mounted therein, metal shell means mounted on the periphery of said housing between said faces, said shell means having an aperture therethrough, said aperture being profiled with recesses along the marginal edges thereof, a pair of stamped and formed metal shields enclosing the rear conductor receiving face of the housing and a cavity extending rearward therefrom, said shields each having hooked tines which are received in respective ones of said recesses and engage said shell means as said shields are rotated about said tines and into engagement to form said cavity, each said shield engaging said shell means in resilient interference between each pair of recesses when said shields are engaged so as to oppose rotation of said shields, thus forming a stored energy preload condition, whereby electrical continuity between the shell means and the shields is assured.
Claim 9
Dependent Claim
35 words
A shielded electrical connector as in claim 6 wherein each shield has a protuberance lying between each pair of tines, each said protuberance engaging said shell means in resilient interference between a pair of recesses.
