In particular, by disposing the locking body 17 so as to cover the sleeve body 6, by a coaxial cable insert operation, the sleeve member 6 enters between the inner insulator 7b and the outer conductor 7c of the coaxial cable 7, the protective coating Since 7d rises around the sleeve body 6 , the locking blade 18 surely bites into the protective coating 7d . Therefore, the rotation of the coaxial cable 7 can be reliably prevented. Further, since the latching body 17 has elasticity, the protective covering 7d is sandwiched between the sleeve body 6 from the inside and the latching body 17 from the outside, and is held more than in the first embodiment. The force is improved, and the rotation prevention function of the coaxial cable 7 can be maintained even if the protective coating 7d of the coaxial cable 7 is plastically deformed due to aging.

In each of the above embodiments, the rotation preventing means is the belt-like protrusion 11 provided on the sleeve body 6 , but as shown in FIG. 9, the protrusion pieces 12a and 12b are in contact with the annular connecting portion 10 with which the end of the coaxial cable 7 abuts. May be provided. In FIG. 9A, protrusion pieces 12a having a horizontally long and sharp tip are provided at two locations, and in FIG. 9B, needle-like protrusions 12b are provided. Even if the rotation preventing means is provided in such a shape, it is effective for preventing the rotation of the coaxial cable 7 . Further, it is more effective if the band-like protrusion 11 and the protrusion pieces 12a and 12b are provided together.
Further, in the second embodiment, the locking blades 18 are provided at four locations around the locking body 17, but even if provided at only two opposing locations, it is sufficiently effective to prevent rotation, and only at one location. Even if it exists, it is possible to exert the rotation stopping power. Furthermore, a larger ratio of the locking blade 18 to bite into the protective coating 7d is effective in preventing the rotation of the coaxial cable 7. However, if the ratio is too large, the protective coating 7d is cut and broken, so the thickness of the protective coating 7d. Is preferably 20% or less, and if it is less, 10% or more is preferable because the rotation-blocking action is weak.

Furthermore, as shown in FIG. 10, the sleeve body 6 of the second embodiment is preferably shaped to prevent the inserted coaxial cable 7 from coming off. Figure 10 is a side view of a sleeve member 6 includes an annular connecting portion 10, (a) the periphery of the sleeve body 6, locking which gave omission by forming an acute angle stop working tip toward the connector front A configuration in which a plurality of rings 34 are provided is shown, and (b) shows a configuration in which a net-like groove, that is, a so-called knurled groove 35 is provided around the sleeve body 6 to provide a retaining action. As described above, when the locking body 17 is provided, it is effective that the sleeve body 6 is not provided with the belt-like protrusion 11 as shown in FIG. In particular, in the case of the knurled groove 35, the coaxial cable 7 can also be prevented from rotating, and the oxide film adhering to the outer conductor 7c of the coaxial cable 7 can be removed, so that the electrical connection is ensured. Further, the retaining process can be applied to the sleeve body 6 of another embodiment.

Next, a third embodiment of the connector according to the present invention will be described with reference to FIG. FIG. 11 is a side view showing the main part in cross section. The difference from FIG. 1 is that the connecting means is a receptacle made of a bolt body 20 having a male thread. In addition, the same code | symbol is provided to the structural member similar to the said FIG. 1, and description is abbreviate | omitted.
In the bolt body 20, a central conductor (not shown) of the connector to be connected is inserted on the central axis M, and a communication hole 22 is formed which communicates with the insertion hole 6 a of the sleeve body 6 in the connector body 21. In the communication hole 22, a connection fitting 23 that connects the center conductor 7 a of the coaxial cable 7 mounted on the connector body 21 and the center conductor (not shown) of the connector to be connected is disposed. The connection fitting 23 is disposed in a resin holding cylinder 24, and the holding cylinder 24 is formed with an insertion hole 24a for inserting a central conductor on the front surface and the back surface.

In assembling this connector, the holding cylinder 24 first assembled with the connecting fitting 23 is inserted into the bolt body 20 from the rear side of the connector body 21, and then the annular connecting portion 10 having the sleeve body 6 is similarly inserted and press-fitted from the rear side. To do. In the same manner as in the first embodiment, the retainer 3, the releaser 5 and the like sandwiched between the fixed sleeve 14 and the fixed ring 15 are assembled.
The installation procedure of the coaxial cable 7 is the same as that of the first embodiment, and the coaxial cable 7 whose end is processed into a predetermined shape is inserted into the connector main body 21 to be securely attached, and tensile stress acts. There is no such thing as missing. The central conductor 7 a of the inserted coaxial cable 7 is inserted into the holding cylinder 24 and is sandwiched between the connecting fittings 23.
Thus, by forming the connecting means as a receptacle, the plugs as in the first embodiment can be connected, the connected central conductors are connected by the connecting fitting 23, and the external conductors are connected by the bolt body 20 The coaxial cables 7 can be well connected with each other. Then, as in the first embodiment, to thereby mounted robust coaxial cable 7 can be withdrawn coaxial cable 7 by operating the releaser 5.

FIG. 12 shows still another embodiment of the connector of the present invention. In the configuration of FIG. 10, the bolt body as the connecting means has the same shape as the connector main body 21, and the coaxial cable 7 can be directly attached. In addition, the same code | symbol is provided to the same component as FIG. 10, and description is abbreviate | omitted.
As shown in FIG. 12, a connector fitting 25 is arranged in which a connecting metal fitting 23 for connecting the central conductors 7a, 7a is arranged at the center, and the connector main body 21 shown in FIG. The whole is formed integrally. In the connector cylinder 25, the sleeve body 6, the retainer 3 and the releaser 5 described above are assembled symmetrically on the left and right.

As described above, the stopper 3 is arranged at a position overlapping the sleeve body 6 , so that even if the diameter of the coaxial cable 7 is reduced, the cable protective covering of the portion that is held by the stopper 3 is retained. The inner diameter of 7d is expanded to a constant diameter by the sleeve body 6 , and the diameter of the protective coating 7d at the portion where the retainer 3 bites does not change. For this reason, the protective coating 7d can always be satisfactorily held, and even if the diameter of the coaxial cable 7 varies, the removal force (tensile stress) of the coaxial cable 7 can be maintained at, for example, 245 N or more and does not easily come off. Further, the length of the connector main body can be shortened by overlapping the stopper 3 and the sleeve body 6 .
Further, as shown in FIG. 14 (b), the annular protrusion 37 formed on the sleeve body 6 spreads the protective covering 7d behind and immediately after the claw portion 3a by the retainer 3, so that the occlusal force is increased. It improves and becomes difficult to come off.

Further, the cross-sectional view shown in FIG. 15 shows a modified example of the connector shown in FIG. 13, and the sleeve body 6 is gradually thinned and thinned toward the rear end as in the first embodiment. It is formed in a shape.
Thus, without providing the annular projection, by disposing the stopper 3 omission to overlap with the sleeve body 6, it is possible to stabilize the bitten force by stopper 3 omission also vary the diameter of the coaxial cable 7 it can.

16 and 17 show a fifth embodiment of the connector of the present invention. Figure 16 is a state of inserting the coaxial cable 7, FIG. 17 shows a state before the cable insertion, the above embodiment, the positional relationship between the rotation preventing means is greatly changed, the mounting structure and the releaser 5 of stopper 3 missing It has been simplified. In addition, the same code | symbol is provided to the structural member similar to the said FIG. 1, and description is abbreviate | omitted.
Internal When according to this embodiment, the annular connecting portion 10 for coupling the connector body 41, which over the rear end of the back, formed integrally with the conical to gradually thin and tip thickness is thinner In addition, a sleeve body 6 having an insertion hole 6a is formed in a projecting manner, and a small-diameter cylindrical fitting portion 16 for projecting a nut body 2 connected from the front portion of the annular connecting portion 10 is formed in a projecting manner. ing. The annular connecting portion 10 is press-fitted and fixed from the front side of the connector main body 41.
Further, the cylindrical fitting portion 16 has an insertion hole through which the inner insulator 7b and the center conductor 7a of the coaxial cable 7 to be attached are inserted, and the inner diameter of the insertion hole 6a formed in the sleeve body 6 is the same. It is installed. The nut body 2 is internally threaded and has a connecting hole 2a for inserting and fitting the cylindrical fitting portion 8 of the connector body 1 at the rear, and is rotatably connected by the cylindrical fitting portion 16. Has been. In addition, after the cylindrical fitting part 16 is fitted with the nut body 2, the tip part 16b is expanded in diameter, and the nut body 2 does not fall off.

The cable insertion port 43 has a stepped portion 43a formed inside the opening. The step 43a has a circumferential diameter that is large enough to allow the frame 3b of the retainer 3 to be inscribed therein, and is placed so that the frame 3b of the retainer 3 contacts the step 43a. After being placed, the distal end portion 43b of the cable insertion port 43 is attached by being reduced in diameter by a spatula or curling.
As the method of attaching the stopper 3 omission, after placing the stopper 3 missing the stepped portion 43a, it may be configured so as to cover the lid to the connector body 41 so as to cover the stepped portion 43a.

Further, a plurality of linear belt-like protrusions 45 are formed as rotation preventing means from the front to the rear of the housing space of the coaxial cable 7 formed on the connector main body 41 from the inner surface of the connector main body 41 toward the central axis direction. ing. For example, the belt-like protrusion 45 is formed in a quadrangular or triangular shape in cross section, and in the embodiment of the present application, the front side is formed so as to be gradually lowered toward the tip.
Thus, since the band-like protrusion 45 is formed inside the connector main body 41, the sleeve body 6 enters between the inner insulator 7b and the outer conductor 7c of the coaxial cable 7 by the coaxial cable insertion operation, and the protective coating 7d. Rises around the sleeve body 6 so that the belt-like protrusion 45 surely bites into the protective coating 7d . That is, according to this embodiment, the protective coating 7d are mounted state of the coaxial cable 7, while being bitten by the claw portions 3a of the stopper 3 exits at the rear end of the connector body 41, the distal end portion of the coaxial cable 7 It is sandwiched between the sleeve body 6 from the inside and the belt-like protrusion 45 from the outside, so that it has an excellent holding force and can reliably prevent the coaxial cable 7 from rotating.
In this embodiment, members such as the locking member 17 and the releaser 5 as in the embodiments already described are not required, so that the material cost and assembly process can be reduced, and the product cost can be reduced. Therefore, it is possible to provide a structure suitable for a coaxial cable connector that requires the above.
In any of the above embodiments, the connector bodies 1, 21, 34, 41 or the connector cylinder 25 have a cylindrical shape, but other shapes, for example, a hexagonal prism shape may be used. Further, the connecting means may have a shape other than the plug or the receptacle structure, and if the cable mounting means in the connector body is configured as described above, the disconnecting action can be satisfactorily exhibited.
Needless to say, the method of forming the band-like protrusion 45 inside the connector main body 41 as in the fifth embodiment may be used in combination with other examples.

FIG. 18 shows an example of an electronic device box (hereinafter simply referred to as a box) according to the present invention. 18 is a cross-sectional explanatory view, 27 is a box, 28 is a circuit board assembled in the box, and 29 is a connector for connecting the coaxial cable 7 . In addition, the same code | symbol is provided to the structural member similar to the said FIG. 1, and description is abbreviate | omitted.

The box 27 is composed of a main body 27a and a cover plate 27b, both of which are made of metal and are formed so that the internal space is electromagnetically shielded. And the connector 29 which connects the coaxial cable 7 is formed in the main body 27a side surface. The connector 29 is configured by projecting a cylindrical connector main body 30 and providing the same cable mounting means as in FIG.
On the other hand, the wall surface of the main body 27 a corresponding to the tip of the connector 29 is formed with a connection hole 31 through which the central conductor 7 a and the inner insulator 7 b of the connected coaxial cable 7 are inserted into the box body 27, and is inserted into the connector main body 30. The central conductor 7a of the coaxial cable 7 is projected into the internal space. Then, the connecting metal fitting 32 for connecting the central conductor 7a is assembled on the circuit board 28 arranged in the box 27 in accordance with the position of the central conductor 7a on the central axis M of the inserted coaxial cable 7. Connection means is configured on the circuit board 28.

In this way, by providing the box with the same cable mounting means as the connector, the mounted coaxial cable 7 does not come off even if a tensile stress is applied by the action of the stopper 3 and is robust. Can be installed. Nevertheless, if the releaser 5 is operated, the removal preventing action by the retainer 3 can be released and can be removed, so that work such as cable replacement can be easily performed. In addition, since the end of the coaxial cable 7 is processed into a predetermined shape and inserted into the connector body, the attachment to the box is completed, so there is no need to separately attach a connector to the coaxial cable 7 and a simple configuration. Can be connected.
Further, since the stopper 3 as a whole has elasticity in the radial direction, the coaxial cable 7 can be inserted smoothly, and the rotation of the coaxial cable 7 can be prevented by the belt-like protrusions formed on the sleeve body 6. Can maintain a secure connection.
Furthermore, the releaser 5 has a simple structure and shape, and the configuration of the cable mounting means does not become complicated.

In this embodiment of the electronic device box, the connector main body 30 protrudes outward from the box 27. However, the cable mounting means is protruded into the inner space of the box 27 in the opposite direction. It may be formed in the body. By doing so, the internal space is narrowed, but the exposed portion of the cable connection portion can be shortened, the connection portion can be strengthened, and the appearance can be improved. Further, although the connecting means is assembled on the circuit board, the connecting bracket 32 may be provided on the connector body 30 side.
A connector having a configuration as in the fourth embodiment shown in FIGS. 13 to 15, that is, a configuration in which the retainer 3 is arranged so as to overlap the sleeve body 6 is also suitable for the electronic device box, and is a coaxial cable. Even if there is variation in the diameter of 7, the stopper 3 can hold the connected coaxial cable 7 well and maintain the removal force at a predetermined value or more, and also against the force in the rotational direction. It has excellent durability and can contribute to shortening the connector body.
Furthermore, the structure of the fifth embodiment shown in FIGS. 16 and 17, that is, a connector having a structure in which a band-like protrusion 45 is formed inside the connector body and the retainer 3 is fixed by curling or the like, is also inexpensive. It is suitable for the target electronic device box.
In addition, in the embodiment, an example in which the releaser 5 is provided in order to have a release function has been shown. However, if the releaser 5 is used in a portion where the release function is not required, it is naturally unnecessary to provide the releaser 5 and the releaser 5 is mounted. Thus, not only is the coaxial cable 7 difficult to be removed, but a connector that is robust against the rotation of the coaxial cable 7 can be constructed at a lower cost.
