Abstract

A coaxial electrical connector comprises an outer contact assembly including a crimping and sealing ferrule that is disposed onto an outer insulating jacket of a multiple outer conductor coaxial cable and includes an inner annular recess in which is disposed a sealing member; a strain relief section of the ferrule is crimpable onto the outer jacket and an outer conductor of the multiple outer conductors of the cable is disposed on a ferrule element. A center contact is crimpable onto a center conductor of the cable and is insertable into a bore of an inner dielectric member of an inner contact assembly and secured therein, whereafter an inner conductor of the multiple outer conductors of the cable is crimpable onto an inner contact of the inner contact assembly thereby forming a terminated inner contact assembly. The terminated inner contact assembly is then positioned into a bore of an outer dielectric member of the outer contact assembly and secured therein when a crimping ferrule section of the outer contact assembly is crimped onto the ferrule element with the outer conductor of the outer conductors electrically connected therebetween.

Claims

1. A coaxial electrical connector for termination onto a center conductor and multiple outer conductors of a coaxial cable, comprising:

center contact means electrically connectable with the center conductor;

ferrule element means disposable between an outer dielectric sheath and an outer conductor of the multiple outer conductors;

inner contact assembly means including inner contact means having inner dielectric means secured therein and ferrule section means along which an inner conductor of the multiple outer conductors is to be positioned, said inner dielectric means having a bore in which said center contact means is to be disposed, crimping member means for crimping the inner conductor to said ferrule section means;

outer contact assembly means including outer contact means having ferrule member means, outer dielectric means secured within said outer contact means, said outer contact means being positionable onto said inner contact assembly means with said outer dielectric means engaging said inner contact means and said ferrule member means being crimpable onto said ferrule element means thereby crimping the outer conductor therebetween, and wherein said outer contact means further includes a strain relief ferrule section disposed beyond said sealing section with respect to said outer contact means and said ferrule member means and crimpable onto an outer jacket of the cable; and

sealing section means as part of said outer contact means including sealing means disposed therewithin and sealingly engageable with the outer jacket of the cable.

2. A coaxial electrical connector as set forth in claim 1, wherein a securing barb on said center contact means secures the center contact means in the bore of said inner dielectric means.

3. A coaxial electrical connector as set forth in claim 1, wherein a gold-plated ring member is press-fitted into a recess in a front surface of said outer contact means to secure said outer dielectric means in said outer contact means and electrically connects with a complementary gold-plated ring member when said coaxial electrical connector is electrically connected with a complementary coaxial electrical connector.

4. A coaxial electrical connector for termination onto a center conductor and multiple outer conductors of a coaxial cable, comprising:

a center contact disposable over the center conductor and crimpable thereover;

an outer contact assembly including a distal outer contact member, an outer dielectric member secured within said outer contact member, a ferrule member joined to said outer contact member, a sealing portion joined to the ferrule member, and a proximal strain relief ferrule section joined to the sealing portion and crimpable onto an outer jacket of the cable, the sealing portion overfitting a portion of said outer jacket and having sealing means therewithin for sealing engaging said outer jacket;

a ferrule element disposable between an outer dielectric sheath and an outer conductor of the multiple outer conductors, said ferrule member of said outer contact assembly being crimpable over said ferrule element with the outer conductor captured therebetween;

an inner contact assembly including an inner contact member, an inner dielectric member secured therein and having a bore through which said center contact extends, and a ferrule section along which an inner conductor of said multiple outer conductors is to be positioned; and

a crimping member disposed coaxially with said inner contact assembly ferrule section and crimpable thereto with said inner conductor captured therebetween.
