Abstract

The invention realizes a CATV repeater which has a reduced distance from a coaxial connector of a coaxial cable to a receptacle on a printed circuit board of an amplifier to prevent deterioration of the high frequency characteristic and besides facilitates connection and is tough against an outdoor environment. Receptacle 32 of amplification device 30 can be inserted into guide metal member 11 of body case 10, and the core of receptacle 32 is connected to core 21 of coaxial connector 20 of a coaxial cable by L-shaped connection pin 13. L-shaped connection pin 13 includes connection pin 13b having, at an end thereof, a cylindrical pin to be fitted with the receptacle of the amplifier and having, at the other end thereof, a U-shaped portion, and connection pin 13a having, at an end portion thereof, a hollow cylindrical portion with a pair of slits on the coaxial cable side and having, at the other end portion thereof, a cylindrical connection portion with ring-shaped projections with which the positioning of the U-shaped portion of connection pin 13b is set in a limited position.

Claims

1. A coaxial cable connection apparatus having a first receptacle in a body case of a CATV repeater for connection of a lead-in coaxial cable and a second receptacle for an amplifier removably mounted in the body case, the first and second receptacles being connected through an L-shaped connection pin, the L-shaped connection pin comprising:

a connection socket for receiving a core pin of the lead-in coaxial cable, said socket comprising a metallic hollow cylinder having at least a pair of slits therein so as to provide resiliency to the hollow cylinder and a cylindrical connection end spaced from said pair of slits, said connection end having pair of spaced apart fixing portions; and

a connection pin having a U-shaped connection end that is slidably connected orthogonally onto said cylindrical connection end of said connection socket between said fixing portions, and having a round rod at its other end for insertion into a core socket of the second receptacle;

said fixing portions being spaced apart a distance larger than a width of said U-shaped connection end so that said U-shaped connection end is laterally slidable on said cylindrical connection end between said fixing portions to change a position of said connection pin relative to said connection socket without breaking a connection therebetween.

2. The connection apparatus for a CATV repeater as set forth in claim 1, wherein each of said fixing portions is a ring-like projection.

3. The connection apparatus for a CATV repeater as set forth in claim 1, wherein said U-shaped connection end comprises a semicircularly folded metal ribbon with the ribbon surface width being greater than a thickness thereof, an interior surface of the width of said folded metal ribbon being in pressural contact with an exterior surface of said cylindrical connection end.

4. A coaxial cable connection apparatus comprising:

a cylindrical connection socket for receiving a core pin of a coaxial cable, said socket comprising an opening at one end for receiving the core pin and a pair of radially extended and spaced apart stops on an exterior surface thereof; and

a connection pin having a U-shaped connection end that is connected to and laterally slidable on the exterior surface of said cylindrical connection socket between said stops, and having a round rod at its other end for insertion into a core socket,

said stops being spaced apart a distance larger than a width of said U-shaped connection end so that said U-shaped connection end is laterally slidable on said cylindrical connection socket between said stops to change a position of said connection pin relative to said connection socket without breaking a connection therebetween.

5. The connector of claim 4, wherein said U-shaped connection end is a folded metal ribbon with a surface width greater than a thickness thereof, and wherein an interior surface of the width of said ribbon is in pressural contact with an exterior surface of said cylindrical connection socket.
