Abstract

A coaxial cable connector having a stopper in a main body for supporting the circumference of the coaxial cable and preventing the coaxial cable from falling out. The stopper is a ring-shaped fastening portion provided in the main body and whose central axis is the same as that of the main body, and a supporting portion which protrudes from the fastening portion in the direction of the central axis of the main body. A rotation-stopping means constituted by a strip-shaped projection is provided on at least an inner surface of the main body to engage the circumference of the coaxial cable. When an end of the coaxial cable is inserted into the main body from behind, the stopper prevents the fall-out of the coaxial cable because the supporting portion supports the circumference of the coaxial cable, and the strip-shaped projection prevents rotation of the coaxial cable.

Claims

1. A coaxial cable connector comprising:

a sleeve having an inserting portion to be inserted into between an inner insulator and an outer conductor of the coaxial cable;

a cylindrical main body provided at the periphery of the inserting portion;

connecting means provided rotatably in front of the sleeve for being connected with the outer conductor of a connecting object, and

a stopper provided in the main body for supporting the circumference of the coaxial cable in order to prevent the fall-out of the coaxial cable,

wherein the stopper is constituted by a ring-shaped fastening portion that is internally provided in the main body so that its central axis is the same as that of the main body, and a supporting portion that is protruded from the fastening portion towards the central axis of the main body,

wherein rotation-stopping means is provided on at least an inner surface of the main body, the rotation-stopping means is constituted by a strip-shaped projection which is longitudinally formed so as to bite into the circumference of the inserted coaxial cable, wherein when an end of the coaxial cable is inserted into the main body of the connector from backward, the stopper prevents the fall-out of the coaxial cable because the supporting portion supports the circumference of the coaxial cable, and the strip-shaped projection prevents rotation of the coaxial cable.

2. The coaxial cable connector according to claim 1, wherein said supporting portion of said stopper is formed such that said distal end thereof is coaxially aligned and in contact with the inserted coaxial cable.

3. The coaxial cable connector according to claim 1, further comprising:

a releaser for releasing the locking force of said stopper that is exerted on the inserted coaxial cable, said releaser including a cylindrical sliding portion for covering the coaxial cable and an operating portion for operating the sliding portion, wherein a distal end of said sliding portion of said releaser abuts the supporting portion of said stopper and pushes said supporting portion up by sliding the sliding portion forward to release the inserted coaxial cable.

4. The coaxial cable connector according to claim 1, further comprising fastening means for fastening the stopper in the main body and preventing the axial movement with respect to the main body and rotation around the axis.

5. The coaxial cable connector according to claim 1, wherein said connecting means comprises a nut female-screwed on an inner surface, and a cylindrical fitting portion on which said nut is fit which protrudes in front of said sleeve in order to support a rear portion of the nut in a rotatable manner;

wherein a through hole is provided in said cylindrical fitting portion through which the inner insulator and a central conductor of the inserted coaxial cable penetrate in series with a through hole of said sleeve; and

wherein the central conductor of the inserted coaxial cable protrudes from a through hole arranged on the central axis of said nut.

6. A coaxial cable connector comprising:

a cylindrical main body into which a coaxial cable is inserted, and

connecting means provided in a front portion of said main body to connect said main body with a connecting object,

wherein said main body includes a sleeve penetrating between an inner insulator and an outer conductor of the inserted coaxial cable and a stopper for preventing the inserted coaxial cable from falling out;

wherein said stopper is formed in a substantially conical shape, wherein an inner diameter of said stopper is smaller than an outer diameter of the inserted cable, wherein an inner peripheral portion of a distal end of said stopper comprises a supporting portion for supporting the circumference of the coaxial cable, and an outer peripheral portion of said distal end of said stopper comprises a fastening portion to fasten said stopper within said main body of said connector, and wherein at least said supporting portion of said stopper has an elastic property in a diameter direction of said stopper;

wherein said supporting portion supports the coaxial cable and prevents the coaxial cable from falling out when an end of the coaxial cable is inserted into the main body of the connector from a rear portion of said connector,

wherein the coaxial cable connector includes rotation-stopping means to prevent rotation of the inserted coaxial cable, said rotation-stopping means being provided perpendicular to a rotation direction of the inserted coaxial cable,

wherein said rotation-stopping means comprises a strip-shaped projection longitudinally formed along a side surface of said sleeve.

7. A coaxial cable connector comprising:

a cylindrical main body into which a coaxial cable is inserted, said main body including a sleeve penetrating between an inner insulator and an outer conductor of the inserted coaxial cable, and a stopper for preventing the inserted coaxial cable from falling out;

connecting means provided in a front portion of said main body to connect said main body with a connecting object; and

rotation-stopping means to prevent rotation of the inserted coaxial cable, said rotation-stopping means comprising a strip-shaped projection longitudinally formed along the side surface of said sleeve;

wherein said stopper is formed in a substantially conical shape, wherein an inner peripheral portion of a distal end of said stopper comprises a supporting portion for supporting the circumference of the coaxial cable, and an outer peripheral portion of said distal end of said stopper comprises a fastening portion to fasten said stopper within said main body of said connector, and wherein at least said supporting portion of said stopper has an elastic property in a diameter direction of said stopper; and

wherein said supporting portion supports the circumference of the coaxial cable and prevents the coaxial cable from falling out when an end of the coaxial cable is inserted into the main body of the connector from a rear portion of said connector.
