Abstract
Abstract A contact terminal for terminating a coaxial cable has a first conductor member with a U-shaped connection portion to receive the conductor core of the coaxial cable; and a second conductor member, electrically insulated from the first conductor member, also having a U-shaped connection portion to receive the conductor tube or screen of the coaxial cable. The second conductor member has a wider base portion than the base portion of the first conductor member. Both U-shaped connector portions are disposed in a line and opened in the same direction to permit the connection to be made merely by laying a partially stripped end of the coaxial cable into the opened connections and folding the opened legs of the first conductor member around the conductor core of the coaxial cable and the opened legs of the second conductor member around the conductor screen of the coaxial cable. The contact terminal may also include an additional clamp which clamps around the core insulating layer to provide further mechanical support.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
220 words
A contact terminal to form an electrical conection with a coaxial cable, said coaxial cable including a conducting core, a core insulating layer surrounding said conducting core, and a conducting shield surrounding said core insulating layer, said contact terminal comprising: a first internal contact member including a first open U-shaped portion having a first part with a base shaped as an internal radial swelling and a second part with a base having a dimension different from the dimension of the base of said first part; a second external contact member having a second open U-shaped portion; said second U-shaped portion being disposed behind said first U-shaped portion with said open U-shaped portions being toward the same side; and, insulating sleeve means disposed between said first and said second members for securing thereof together and preventing any relative displacement thereof, said insulating sleeve means comprising three coaxial portions, one of said coaxial portions being an extra-thickness portion between said said two other coaxial portions and thicker than said two other coaxial portions and assuming substantially the exact shape of said internal radial swelling of said first internal contact member, said one of said coaxial portions coinciding with the base of said first part and one of the other of said two coaxial portions coinciding with the base of said second part.
Claim 2
Dependent Claim
220 words
A contact terminal to form an electrical conection with a coaxial cable, said coaxial cable including a conducting core, a core insulating layer surrounding said conducting core, and a conducting shield surrounding said core insulating layer, said contact terminal comprising: a first internal contact member including a first open U-shaped portion having a first part with a base shaped as an internal radial swelling and a second part with a base having a dimension different from the dimension of the base of said first part; a second external contact member having a second open U-shaped portion; said second U-shaped portion being disposed behind said first U-shaped portion with said open U-shaped portions being toward the same side; and, insulating sleeve means disposed between said first and said second members for securing thereof together and preventing any relative displacement thereof, said insulating sleeve means comprising three coaxial portions, one of said coaxial portions being an extra-thickness portion between said said two other coaxial portions and thicker than said two other coaxial portions and assuming substantially the exact shape of said internal radial swelling of said first internal contact member, said one of said coaxial portions coinciding with the base of said first part and one of the other of said two coaxial portions coinciding with the base of said second part.
Claim 3
Dependent Claim
20 words
The contact terminal of claim 1 wherein said second U-shaped member has a base wider than said first U-shaped member.
Claim 4
Dependent Claim
22 words
A contact terminal according to claim 1, in which at least one said U-shaped portions is provided with an internal contact fork.
Claim 5
Dependent Claim
19 words
A contact terminal according to claim 3, in which at least one of said internal contact forks is self-stripping.
Claim 6
Dependent Claim
94 words
The contact terminal according to claim 2, further including a third U-shaped portion which is disposed between the two other U-shaped portions in line therewith, and open at the same side, the base portion of said third U-shaped portion being of a width which is less than the width of the base portion of the U-shaped portion of the second member and greater than or equal to the width of the base portion of the U-shaped portion of the first member, to permit a mechanical connection of the terminal to the core insulating layer.
Claim 7
Dependent Claim
129 words
A contact terminal according to claim 2, 3 or 4, wherein said terminal is in coaxial form, further comprising a central member an insulating sheath and a peripheral member, said central member surrounded by said peripheral member; said central member forming said first member with said first U-shaped portion forming one of the ends of a body whose other end forms a contact head, and the peripheral member forming said second member with said second U-shaped portion connected by an intermediate portion to a tubular body which encloses said insulating sheath, said insulating sheath surrounding the body of the central member and being extended by an insulating tongue portion which is housed between said second U-shaped portion of said peripheral member and said intermediate portion of said peripheral member.
Claim 8
Dependent Claim
126 words
A contact terminal according to claim 5, wherein said terminal is in coaxial form, further comprising a central member an insulating sheath and a peripheral member, said central member surrounded by said peripheral member; said central member forming said first member with said first U-shaped portion forming one of the ends of a body whose other end forms a contact head, and the peripheral member forming said second member with said second U-shaped portion connected by an intermediate portion to a tubular body which encloses said insulating sheath, said insulating sheath surrounding the body of the central member and being extended by an insulating tongue portion which is housed between said second U-shaped portion of said peripheral member and said intermediate portion of said peripheral member.
Claim 9
Dependent Claim
51 words
A contact terminal according to claim 7 wherein said third U-shaped portion is carried by the central member behind the U-shaped portion which has the narrower base portion, with respect to the body of said central member, said insulating tongue portion extending between said third U-shaped portion and said intermediate portion.
Claim 10
Dependent Claim
32 words
A contact terminal according to claim 7 wherein said third U-shaped portion is carried by the peripheral member between the U-shaped portion which has the wider base portion and said intermediate portion.
Claim 11
Dependent Claim
64 words
A contact terminal according to claim 7, 8 or 9, in which said intermediate portion comprises two side flank portions capable of being bent over and is also of U-shaped section so that, after connection of the coaxial cable, bending over of said side flank portions around the portions of the central member which is connected to the cable, provides protection for said portion.
Claim 12
Dependent Claim
72 words
The contact terminal according to claim 10, wherein the height of said side flank portions is such that they can be bent over towards each other, extending the tubular shape of the body of the peripheral member and defining an air pocket which serves as a dielectric around the part, which is not surrounded by the insulating tongue portion, of the portion of the central member which is connected to the cable.
Claim 13
Dependent Claim
64 words
A contact terminal according to claim 7 further comprising a carrier strip, said carrier strip mounting a plurality of said terminals at a given pitch, to form a continuous strip, which connection makes it possible easily to automate the formation of a crimped connection between a coaxial cable and each of the terminals, the carrier strip being sheared off when the connection is made.
Claim 14
Dependent Claim
34 words
A contact terminal as claimed in claim 1, including an external radial swelling forming part of said second external contact member for coinciding with said internal radial swelling of said first internal contact member.
