Abstract
Abstract A hybrid filter header is disclosed for use in electro-explosive devices to assure shorting of the contacts in a disconnected condition thereby avoiding accidental detonation of the explosive device. The subject hybrid filter header is mounted in a receptacle member of a connector and includes at least two pin contacts, each mounted in a respective filter sleeve and secured in a ground plane adopted to be forced fitted into the receptacle housing. The terminals are encompassed between a pair of locking spring members that effect shorting of the terminals to the ground plane in a disconnected condition. The mating plug member includes an insulated portion which spreads the spring members to disengage them from the terminals and to engage therewith in a locking relationship to hold the connector members together.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
157 words
A hybrid filtered header for an electrical connector providing RFI/EMI filtering and grounding protection to associated circuitry, said header comprising: a ground plane adapted to be received in an aperture of one of a mating pair of connector members; at least one filtered terminal mounted in said ground plane, said filtered terminal including a cylindrical filter sleeve electrically connected to said ground plane by its outer diameter and a terminal member electrically connected to the inner diameter of said filter sleeve; a spring member having one end electrically connected to said ground plane with a resilient arm extending therefrom in cantilever fashion, said arm being biased so that the free end thereof normally engages said filtered terminal shorting it to ground; and a profiled projection of insulative material on a mating connector, said projection having a forwardly directed profile adapted to cam said spring member arm away from an associated terminal upon mating of said connector members.
Claim 2
Dependent Claim
157 words
A hybrid filtered header for an electrical connector providing RFI/EMI filtering and grounding protection to associated circuitry, said header comprising: a ground plane adapted to be received in an aperture of one of a mating pair of connector members; at least one filtered terminal mounted in said ground plane, said filtered terminal including a cylindrical filter sleeve electrically connected to said ground plane by its outer diameter and a terminal member electrically connected to the inner diameter of said filter sleeve; a spring member having one end electrically connected to said ground plane with a resilient arm extending therefrom in cantilever fashion, said arm being biased so that the free end thereof normally engages said filtered terminal shorting it to ground; and a profiled projection of insulative material on a mating connector, said projection having a forwardly directed profile adapted to cam said spring member arm away from an associated terminal upon mating of said connector members.
Claim 3
Dependent Claim
36 words
A hybrid filtered header according to claim 1 further comprising: at least one latching detent in said profiled projection adapted to latchingly engage with said arm of said spring member to lock said connector members together.
Claim 4
Dependent Claim
69 words
A hybrid filtered header according to claim 1 wherein said at least one filtered terminal comprises: a pair of filtered terminals secured to said ground plane in parallel spaced relation; said spring member arm having a transverse flange on the free end thereof, said flange engaging both said filtered terminals in the normal position; and said profiled projection lying intermediate of said filtered terminals and acting on said flange.
Claim 5
Dependent Claim
56 words
A hybrid filtered header according to claim 3 wherein said spring member comprises: a pair of substantially parallel resilient arms extending from said ground plane in cantilever fashion, each said arm having a transverse flange on the free end thereof, said arms lying on opposite sides of said terminals with said flanges normally contacting said terminals.
Claim 6
Dependent Claim
28 words
A hybrid filtered header according to claim 1 wherein said ground plane is mounted in a receptacle member of a connector, and said terminal members are pin contacts.
Claim 7
Dependent Claim
72 words
A hybrid filtered header according to claim 1 wherein said spring member comprises: a base portion secured to said ground plane; a pair of resilient arms extending from said base portion in cantilever fashion in substantially parallel relation, each said arm having a transverse flange on a free end thereof, said flanges normally engaging said filtered terminals and latchingly engaging said profiled projection in a fully mated condition of said connector members.
