Description

  The present invention relates to an improved structure of a coaxial cable connector capable of increasing the coupling tightness of a coaxial cable, and more particularly to a cable having a signal transmission function, for example, a coaxial cable or a similar structure.

  In general, a cable television (CATV) system or a joint antenna television system is connected to a distributor via a trunk line, and is further output from the distributor to a branch line to be connected to a user terminal and transmitted from the television system. It has become a mechanism to receive. In the trunk line, a coaxial connector is coupled to a terminal of a coaxial cable, and the trunk line is arranged in the distributor by the coaxial connector.

  As shown in FIG. 6, the conventional coaxial connector is an F-type coaxial cable connector, and includes a sandwiching sleeve A1, a columnar member B arranged coaxially in the sleeve A1, an O-shaped ring C, and a columnar shape. A connector main body A including a nut D disposed around the member B is included. The free end of the coaxial cable 80 is inserted into the terminal A2 of the connector main body A, the insulator 82 and the core conductor 81 are positioned in the columnar member B, and the braided wire 83 and the sheath 84 are arranged outside the columnar member B. Between the sleeve 84 and the holding sleeve A1, and a pressure is applied to the holding sleeve A1 with a presser so that the sheath 84 of the coaxial cable 80 is sealed.

  However, when such a connector is coupled to the coaxial cable, it is necessary to tightly couple the holding sleeve A1 and the coaxial cable with the holding device. However, when the holding device is used, the sleeve A1 and the coaxial cable are used. The closeness between the two and the 80 must be well confirmed, and if the applied pressure is only a little, it leads to the disadvantage that the connection becomes tight.

  The present invention has been made in view of the above points, and provides an improved structure of a coaxial cable connector capable of achieving both close coupling and convenient operation of the coaxial cable and the connector.

  A main object of the present invention is to provide an improved structure of a coaxial cable connector that has few parts, is easy to operate, and can achieve a tight coupling density.

  To achieve the above object, an improved structure of a coaxial cable connector according to the present invention includes a connector head and a sleeve member coupled to the connector head. The sleeve member includes a shaft tube, a sleeve, and a metal sleeve, the shaft tube is inserted into the sleeve, and a locking portion, a cushion portion, and a receiving portion are sequentially formed at the other end of the sleeve, A stepped portion is formed at a connecting portion between the locking portion and the cushion portion, the metal sleeve is inserted into the locking portion, and one end of the metal sleeve is brought into contact with the stepped portion, thereby being coaxial. After the cable is inserted from the rear side of the sleeve member, the insulating layer at the tip of the coaxial cable is matched with the edge of the shaft tube, and pressure is applied to the sleeve member with a tool, so that the metal sleeve is moved forward. The latching portion is ruptured and separated from the sleeve, and is further clamped by the restriction of the metal sleeve while being pushed forward continuously along the top surface of the cushion portion. The Deployment unit let me pressed downward, increasing the tightness of the coupling between the coaxial cable and the connector.

The improved structure of the coaxial cable connector according to the present invention has the following advantages.
(1) With a simple component, the coupling operation becomes very convenient, and when the sleeve member and the coaxial cable are coupled, they can be coupled closely.
(2) Due to the special design of the cushion portion and the receiving portion of the sleeve, when the locking portion is torn and pressed, the operation is convenient by dispersing the force due to deformation.
(3) The special design of the stepped portion of the sleeve makes it easy to control the tearing of the locking portion of the sleeve in accordance with the operation of the physical principles of physics, achieve the intended purpose, and is easy to implement. is there.
