Abstract
Abstract A plug connection arrangement or electrical connector includes at least one plug element with an electrical contact member to produce an electrical connection of a cable with a complementary contact member and a connection housing with at least one plug-holding fixture with the complementary contact member. An electrical shielding of the connection housing has a flexible shield contact spring extending into the plug-holding fixture and pre-biased for contacting the complementing contact member of the plug-holding fixture. A coaxial insulating body surrounds the contact member of the plug element in a contact-proof and shock-proof manner. A groove extends in the plug element exterior surface in a longitudinal direction, and holds the contact spring end part upon the insertion of the plug element into the plug-holding fixture.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
182 words
An electrical connector, comprising: at least one plug element, connectable to a cable, having a plug electrical contact member and a tubular insulating body surrounding and extending coaxially relative to said plug contact member, said insulating body being open at one end thereof to provide access to said plug contact member; a connection housing including at least one plug-holding fixture for receiving said plug element, said plug-holding fixture having a contact member mateable with said plug contact member and extendable through said open end of said insulating body; electrical shielding coupled to said connection housing, said electrical shielding having a flexible shield contact spring extending into said plug-holding fixture, said shield contact spring having an end part pre-biased to contact said housing contact member; and a groove extending in an exterior surface of said insulating body parallel to a longitudinal axis thereof, said groove having a width adapted to a breadth of said shield contact spring to receive said end part as said end part is disconnected from said housing contact member upon insertion of said plug element into said plug-holding fixture.
Claim 2
Dependent Claim
182 words
An electrical connector, comprising: at least one plug element, connectable to a cable, having a plug electrical contact member and a tubular insulating body surrounding and extending coaxially relative to said plug contact member, said insulating body being open at one end thereof to provide access to said plug contact member; a connection housing including at least one plug-holding fixture for receiving said plug element, said plug-holding fixture having a contact member mateable with said plug contact member and extendable through said open end of said insulating body; electrical shielding coupled to said connection housing, said electrical shielding having a flexible shield contact spring extending into said plug-holding fixture, said shield contact spring having an end part pre-biased to contact said housing contact member; and a groove extending in an exterior surface of said insulating body parallel to a longitudinal axis thereof, said groove having a width adapted to a breadth of said shield contact spring to receive said end part as said end part is disconnected from said housing contact member upon insertion of said plug element into said plug-holding fixture.
Claim 3
Dependent Claim
41 words
An electrical connector according to claim 1 wherein said electrical shielding is located on a wall of said connection housing; and said shield contact spring extends through a passage in said connection housing from said electrical shielding into said plug-holding fixture.
Claim 4
Dependent Claim
22 words
An electrical connector according to claim 2 wherein said shield contact spring is unitarily formed as one piece with said electrical shielding.
Claim 5
Dependent Claim
22 words
An electrical connector according to claim 1 wherein said shield contact spring is unitarily formed as one piece with said electrical shielding.
Claim 6
Dependent Claim
20 words
An electrical connector according to claim 1 wherein said electrical shielding and said contact spring are made of spring plate.
Claim 7
Dependent Claim
20 words
An electrical connector according to claim 2 wherein said electrical shielding and said contact spring are made of spring plate.
Claim 8
Dependent Claim
41 words
An electrical connector according to claim 1 wherein said plug element comprises a shield contact connectable to shielding of a cable, said shield contact lying exposed at a base of said groove and being electrically connectable with said shield contact spring.
Claim 9
Dependent Claim
65 words
An electrical connector according to claim 7 wherein said shield contact comprise a metal tube which can surround an exterior of the cable; and said tubular insulating body comprises an interior insulating tube and an exterior insulating tube having on opposite sides of said metal tube, said exterior insulating tube having said groove in which said metal tube lies exposed for engaging said contact spring.
Claim 10
Dependent Claim
43 words
An electrical connector according to claim 8 wherein said metal tube comprises a catch projection located in said groove of said exterior insulating tube and cooperating with said contact spring to form a releasable catch between said plug element and said plug-holding fixture.
Claim 11
Dependent Claim
62 words
An electrical connector according to claim 1 wherein said plug element comprises a cross piece projecting laterally outwardly; said connection housing comprises a mating formation in which said cross piece can be received in an access area of said plug-holding fixture to set and hold said plug element in a proper orientation upon insertion of said plug element in said plug-holding fixture.
Claim 12
Dependent Claim
27 words
An electrical connector according to claim 10 wherein said plug element is joined in a plug set to other plug elements by cross pieces extending laterally therebetween.
