Abstract

For connecting a coaxial cable to a tap box housing a highfrequency circuit, a first connector element comprising an outer conductor is secured to the box and is provided with a center contact which is secured at one end to the circuit, the other end being a socket with a conical bore. A second connector element is secured to the face end of the first element and includes an outer cylindrical member secured to the outer conductor of the cable and having centrally located spring fingers through which the inner conductor of the cable extends, the spring fingers being forced to grip the center conductor where the spring fingers enter the conical bore when the two connector elements are assembled.

Claims

1. A coaxial line terminal adapter element for detachable connection of a receptacle, comprising:

a hollow conductor body member having a cylindrical bore therethrough, means in said bore for conductively securing the body member to the end portion of an outer conductor of a coaxial line, insulating means mounted within the bore, a collet having an unobstructed opening therethrough for receiving the inner conductor of the line supported by said insulating means centrally of the bore, the collet being longitudinally slotted to provide a socket having a plurality of fingers between which the central conductor of the coaxial line slidably extends when the outer conductor of the coaxial line is disposed in the body member, a ferrule member supporting the insulating means and slidably mounted within the cylindrical bore, means within the bore providing radially inwardly extending circumferential ledge means, the means for securing the body member to the outer conductor of the cable comprising a resilient split sleeve coaxial with the bore and disposed between the ledge means and an inner end wall provided on the ferrule member, said ledge means and said inner end wall being provided with camming means to cause radial compression of the sleeve in response to relative axial movement of the ferrule and ledge means toward each other, said receptacle being provided with engaging means for detachably engaging the body member, said receptacle having bearing means for bearing against and moving the ferrule member axially against the split sleeve, said receptacle provided with a bore therethrough, and insulating means provided within the receptacle bore for supporting a conductive socket member concentrically therewithin, said socket member including an opening to receive the spring fingers therein.

2. A coaxial line terminal adapter element for detachable connection of a receptacle, comprising:

a hollow conductor body member having a cylindrical bore therethrough, means in said bore for conductively securing the body member to the end portion of an outer conductor of a coaxial line, insulating means mounted within the bore, a collet having an unobstructed opening therethrough for receiving the inner conductor of the line supported by said insulating means centrally of the bore, the collet being longitudinally slotted to provide a socket having a plurality of fingers between which the central conductor of the coaxial line slidably extends when the outer conductor of the coaxial line is disposed in the body member, a ferrule member supporting the insulating means and slidably mounted within the cylindrical bore, means within the bore providing radially inwardly extending circumferential ledge means, the means for securing the body member to the outer conductor of the cable comprising a resilient split sleeve coaxial with the bore and disposed between the ledge means and an inner end wall provided on the ferrule member, said ledge means and said inner end wall being provided with camming means to cause radial compression of the sleeve in response to relative axial movement of the ferrule and ledge means toward each other, said receptacle being provided with engaging means for detachably engaging the body member, said receptacle having bearing Means for bearing against and moving the ferrule member axially against the split sleeve, a socket member supported in the receptacle and provided with an opening which is substantially conical and divergent toward one end of said socket.

3. A coaxial line terminal adapter element for detachable connection of a receptacle, comprising:

a hollow conductor body member having a cylindrical bore therethrough, means in said bore for conductively securing the body member to the end portion of an outer conductor of a coaxial line, insulating means mounted within the bore, a collet having an unobstructed opening therethrough for receiving the inner conductor of the line supported by said insulating means centrally of the bore, the collet being longitudinally slotted to provide a socket having a plurality of fingers between which the central conductor of the coaxial line slidably extends when the outer conductor of the coaxial line is disposed in the body member, a ferrule member supporting the insulating means and slidably mounted within the cylindrical bore, means within the bore providing radially inwardly extending circumferential ledge means, the means for securing the body member to the outer conductor of the cable comprising a resilient split sleeve coaxial with the bore and disposed between the ledge means and an inner end wall provided on the ferrule member, said ledge means and said inner end wall being provided with camming means to cause radial compression of the sleeve in response to relative axial movement of the ferrule and ledge means toward each other, said receptacle being provided with engaging means for detachably engaging the body member, said receptacle having bearing means for bearing against and moving the ferrule member axially against the split sleeve, the insulating means supporting the socket comprises a centrally apertured bead extending across the bore, and the socket having a portion thereof extending through the apertured bead with the socket extending from the apertured bead and provided with radially extending projecting means respectively abutting opposed surfaces of the bead for captivating the socket against axial movement.

4. The structure as recited in claim 1, wherein one end of said receptacle is provided with means for detachably connecting the receptacle to a housing for a circuit board.
