Coaxial cable connector plug
First Claim
1. A coaxial cable connector plug for electrically connecting a coaxial cable including a center conductor, an inner insulation covering said center conductor, and an outer conductor, to a connector receptacle having a receptacle opening, said connector plug comprising:
- a connection member including a contact portion being electrically connected to said center conductor of said coaxial cable, and a pin portion being electrically connected to said contact portion and being adapted to be electrically connected to said connector receptacle;
said contact portion and said pin portion of said connection member being integrally made of a single metallic plate, said contact portion being formed at one longitudinal end of said metallic plate and said pin portion being formed at the other longitudinal end of said metallic plate, an engaging portion being further formed in said connection member at a position intermediate said contact portion and said pin portion and protruding in a direction orthogonal to the longitudinal direction of said connection member;
said engaging portion comprising two layered engaging pieces facing each other and formed by folding said single metallic plate;
an inner casing made of an insulating material and receiving said contact portion of said connection member, said inner casing comprising first and second portions, said first portion including a first aperture for guiding said center conductor of said coaxial cable into the inside of said inner casing, at least one of said first portion and said second portion having a groove formed therein, said groove receiving said engaging portion of said connection member, and a second aperture formed in said second portion, said pin portion extending through said second aperture and outside said inner casing;
a shield casing made of a conductive material for covering said inner casing, said shield casing having openings formed at both ends thereof, one opening of said shield casing being adapted to receive said inner insulation of said coaxial cable; and
connecting/fixing means for electrically connecting and fixing said outer conductor of said coaxial cable to said shield casing.

Abstract
A coaxial cable is electrically connected to a connector receptacle by means of a coaxial cable connector plug. The coaxial cable connector plug comprises a clip which acts as an elastic pressure contact connected to a central conductor of the coaxial cable, and a plug pin electrically connected to the clip and adapted to be inserted into a receptacle opening of the connector receptacle. The clip and the plug pin are integrally formed in a single metallic plate. The clip is formed by folding the metallic plate at one end portion, while the plug pin is formed at the other end portion of the metallic plate by curling the same, with engaging portions being formed at the joint portion of the clip and the plug pin and protruding in the direction orthogonal to the longitudinal direction. The clip is housed in an insulating inner casing, while the pin is guided outward extending therefrom. The inner casing is covered with a shield casing. The inner casing is formed with an aperture for insertion of a center conductor of a coaxial cable at the position corresponding to the clip and the shield casing is formed with an aperture for insertion of an inner insulation of the coaxial cable at the corresponding portion. An outer conductor of the coaxial cable is pressure fixed to the side surface of the shield casing.
