Description

[Detailed description of the invention] (a) Technical field of the invention The invention relates to an improvement of a coaxial cable connector used for connections between communication devices and electronic devices, or between an antenna and a device using a coaxial cable. .

(b) Conventional technology and problems Conventionally, this type of coaxial cable connector
As shown in the figure, a cylindrical main body 1 having an internal conductor connection terminal 3 supported by an insulator 2 at the center;
A coaxial cable consisting of a cylindrical body 4 equipped with a cable fixing means 5 that is fitted and integrated with one end of the cylindrical main body 1, and in which an outer conductor 7 made of, for example, a braided wire, an insulating layer 8 and an inner conductor 9 are exposed in this order in advance. 6 was inserted into the cylindrical body 4, and the internal conductor 9 of the cable 6 was connected to one end of the internal conductor connecting terminal 3 in the cylindrical main body 1 by soldering. After that, the cylindrical body 4 is fitted to one end side of the cylindrical main body 1 as shown in the figure, and is integrated with screws, and the jacket of the cable 6 and the exposed external conductor 7 are
The portions are fixed by means of fixing means 5 screwed by connection fixing fittings 10.

However, in the connection structure between the coaxial cable 6 and the connector as shown in Fig. 1, the connection strength between the internal conductor 9 of the coaxial cable 6 and the connection terminal 3 on the connector side depends only on the strength of soldering. Since there is no protection against the fact that the internal conductor 9 is likely to be cut or bent at the base of the soldering part during handling, reliability against such problems is poor, and it is inconvenient that special tools must be used for soldering. There is. Furthermore, when soldering, the heating temperature deforms or melts the resin insulating layer 8 made of polyethylene, nylon, etc. that covers the internal conductor 9, resulting in unstable electrical characteristics. Ta.

(c) Purpose of the invention The present invention was devised in view of the above-mentioned drawbacks of the conventional technology, and it is possible to easily connect a coaxial cable to a connector by not using soldering and by using a simple connecting component structure that is less likely to break. It is an object of the present invention to provide a highly reliable coaxial cable connector that can be connected.

(d) Structure of the invention According to the invention, this purpose is to provide an insulating layer at the terminal part of a coaxial cable having an outer conductor between a central inner conductor, an insulating layer covering the inner conductor, and an outer covering layer. A two-part tapered conductor connector with a built-in engaging claw that is fixed by being broken and connected to the internal conductor, and a locking pin implanted on the outer periphery, and the conductor connector is inserted into one end for connection. Preferably, an internal conductor connector is provided with a tapered connection hole having a locking groove on its inner wall surface and a protruding terminal at the other end; This is achieved by providing a coaxial cable connector characterized by comprising a conductive cylindrical body having a means for fixing the coaxial cable and an open end at the other end.

(e) Embodiments of the invention Preferred embodiments of the invention will be described in detail below with reference to the drawings.

FIGS. 2 and 3 are a partially cutaway top view and a sectional view of a main part of an embodiment of the coaxial cable connector according to the present invention. As shown in these two figures, the coaxial cable connector of the present invention includes a tapered conductor connector 21 that connects and fixes the terminal internal conductor 33 of the coaxial cable 30, and a tapered conductor connector 21 that is fitted into one end. Tapered connection hole 2 with a locking groove (not shown) on the inner surface for connection
3, and a conductive flange-shaped cylindrical main body 26 in which an internal conductor connector 22 integrally provided with a protruding terminal 24 at the other end is disposed through an insulator 25 made of Teflon or the like. Note that the cylindrical main body 26
The coaxial cable 30 is fixed on one end side from above the jacket 31, and is provided with a fixing means consisting of a fixing part 27 that is conductively connected to the exposed external conductor 32 portion and a fixing fitting 28 that is fixed with a screw 29, and the other end side is open. It is at the edge. Further, the tapered conductor connector 21
As shown in FIG. 4, it consists of two connecting conductor pieces 21a and 21b divided into two, and is fixed to the outer peripheral surface of one of the connecting conductor pieces 21a and 21b, for example, 21a. A pin 21d is implanted, and an engaging pawl 21c is attached to the inner surface of the cable fixation, which breaks the insulating layer 33 of the coaxial cable and connects it to the internal conductor 34 by crimping. Further, both the connecting conductor pieces 21a and 2
The cable fixing inner surface of 1b is provided with an uneven surface to prevent slipping.

However, in order to connect the coaxial cable 30 using the connector of the present invention configured as described above, first, the outer sheath 31 at the terminal of the cable 30 and the outer conductor 32 made of a braided wire are stripped to an appropriate length. After processing, the two-part tapered conductor connector 2 is attached to the terminal portion of the cable 30 where the insulating layer 33 is exposed.
1 with screws 21e, and the tapered conductor connector 21 is connected to the internal conductor 34 and the engaging claw 21.
Connect and fix via c. Next, the tapered conductor connector 21 fixed to the end of the coaxial cable 30 in this manner is inserted into the tapered connection hole 23 of the internal conductor connector 22 provided in the cylindrical main body 26 into a locking groove (not shown). After fitting by inserting the locking pin 21d, turning the conductor connector 21 slightly clockwise, for example, and locking it with the locking pin 21d, and connecting both 21 and 23 by fitting, The boundary between the jacket 31 of the coaxial cable 30 and the outer conductor 32 is fixed to the fixing part 27 of the cylindrical main body 26 with a screw 29 using a fixing fitting 28 as shown in the figure.
The electrical connection between the main body 26 and the cylindrical main body 26 and the fixing of the connector to the coaxial cable 30 are simultaneously performed.

(f) Effect of the invention As is clear from the above explanation, according to the structure of the coaxial cable connector of the invention, only the outer sheath and outer conductor at the terminal part of the coaxial cable connected to the connector can be made to a predetermined length. Only step stripping is required, and the electrical connection and mechanical fixation between the coaxial cable and the connector can be easily performed using a commonly used screwdriver without the need for soldering. This has the advantage that the connection work can be made more efficient. Also, since the internal conductor is fixed inside the tapered connector together with the insulating layer,
The strength of the connection between the internal conductor and the connector side is compensated, there is no disconnection as in the conventional case, and reliability is improved, making it extremely practical when applied to connectors for various coaxial cables.
