Abstract

Abstract A miniature bulkhead connector (10) is disclosed having a novel anti-rotational mechanism for preventing rotation of the center conductor (90) during mating with a mating connector. The connector includes a metal housing (14) arranged to be mounted to a bulkhead (20) and an insulating insert (40) in a cavity (38) within the housing. The insert (40) has a central hole (54) therethrough on the longitudinal axis (43) of the insert. A series of ribs (62) are formed on the interior surface of the central hole (54) parallel with the axis and are arranged to form channels (64) between adjacent ribs. the channels (64) are sized to receive edges (94) that project from opposite sides of the contact (56). The edges (94) slide into the channels (64) allowing the contact to freely move along the longitudinal axis (43) but will not permit relative rotation thereof. Since there are a number of channels, there is a similar number of angular positions from which the contact may be inserted into the insulating insert.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 85 words
An electrical connector comprising: (a) a housing having a cavity therein; (b) an insulating insert in said cavity, said insert having a longitudinal axis and an opening therethrough substantially coaxial with said axis; and (c) a contact adapted to be connected to the conductor of a cable, said contact arranged to be received within said opening in any of a plurality of angular positions, wherein said contact is inhibited from rotational movement with respect to said insert yet free to move axially along said axis.
Claim 2
Dependent Claim 85 words
An electrical connector comprising: (a) a housing having a cavity therein; (b) an insulating insert in said cavity, said insert having a longitudinal axis and an opening therethrough substantially coaxial with said axis; and (c) a contact adapted to be connected to the conductor of a cable, said contact arranged to be received within said opening in any of a plurality of angular positions, wherein said contact is inhibited from rotational movement with respect to said insert yet free to move axially along said axis.
Claim 3
Dependent Claim 30 words
The connector according to claim 1 wherein said housing includes a projection extending into said cavity and engages said insert and prevents rotational movement thereof with respect to said housing.
Claim 4
Dependent Claim 70 words
The connector according to claim 2 wherein said opening of said insert includes a plurality of angularly spaced ribs extending radially into said opening substantially parallel with said axis, thereby forming a plurality of channels, one channel being between each pair of adjacent ribs, and said contact includes a first edge portion that extends within one of said channels thereby effecting said rotational coupling of said contact to said insert.
Claim 5
Dependent Claim 27 words
The connector according to claim 3 wherein said contact includes a second edge portion that extends within another one of said channels substantially opposite said one channel.
Claim 6
Dependent Claim 35 words
The connector according to claim 4 wherein said first and second edge portions extend into their respective channels with sufficient clearance to effect said free axial movement of said contact with respect to said housing.
Claim 7
Dependent Claim 45 words
The connector according to claim 3 wherein said contact includes a contact portion for electrically engaging a mating contact and a crimping portion for crimping onto said conductor of said cable, wherein said first edge portion is between said contact portion and said crimping portion.
Claim 8
Dependent Claim 13 words
The connector according to claim 3 wherein said connector is a coaxial connector.
