Similar to the sleeve body 6, the belt-like protrusion 11 is formed so as to be gradually lowered from the annular coupling portion 10 toward the tip.

Note that the number of the belt-like protrusions 11 may be only one, or it may not be formed entirely from the base portion to the rear end portion of the sleeve body 6 but may be provided only in a part. Further, the insertion hole 6a of the sleeve body 6 and the insertion hole 8a formed in the cylindrical fitting portion 8 on the front surface of the connector body 1 are formed with the same diameter on the connector center axis M, and the sleeve body 6 is a connector. It can also be formed integrally with the main body 1. The cylindrical fitting portion 8 may be formed integrally with the sleeve body 6 by being connected to the annular connecting portion 10 and is not limited to the embodiment.

As shown in the front view of FIG. 3A, the retainer 3 is formed in a substantially disk shape and is made of an elastic metal, for example, stainless steel for springs.
The retainer 3 is provided with a ring-shaped frame 3b having the same central axis as the central axis of the connector body 1, and projecting from the ring-shaped frame 3b toward the center line of the frame 3b. And a plurality of claw portions 3a.
The tip of the claw 3a has a trapezoidal shape in the embodiment of the present invention. However, if the cable can be easily inserted, the tip may be sharply sharpened, or the cable may be pulled out. In order to further increase the proof strength against the direction force, the inner diameter of the claw portion 3a is formed to be smaller than the outer diameter of the cable 7 to be attached, and the inner circumference is such that the tip thereof is in line contact with the cable 7.

Therefore, the frame body 3b is not deformed, the bending angle θ of the claw portion 3a of the retainer 3 is maintained, and the biting operation is performed satisfactorily.

When the stopper 3 is manufactured, it is manufactured by punching, and then the claw portion 3a is bent. The punching of the claw portion 3a is preferably performed from the front (left side in FIG. 3B). By doing so, an end portion (the inner peripheral end portion on the left side of FIG. 3B) of the claw portion 3a on the opposite side is formed at an acute angle so that the cable 7 can be securely bitten. Can be made. In FIG. 3, six claw portions 3a are formed, but the number can be easily changed by changing the width of the notches.

The retainer 3 formed in this manner is assembled to the connector body 1 after being secured to the retainer 4. The fixing tool 4 includes a fixing sleeve 14 that is locked to the connector body 1 and a fixing ring 15 that fixes the retaining tool 3 to the fixing sleeve 14, and the fixing sleeve 14 is a stepped part that latches the retaining tool 3 on the inner surface. 14a and a releaser insertion portion 14b. The fixing ring 15 is formed with the same diameter as that of the retainer 3. The retainer 3 is fixed to the retainer 4 by inserting the retainer 3 from the front surface of the fixed sleeve 14 to the locking position and inserting the fixing ring 15, and pressing the tip opening of the fixed sleeve 14 with a press or the like. Reduce diameter. Thus, the fixing ring 15 is prevented from coming off, and the stopper 3 is clamped and fixed in the fixing 4.
Then, the retainer 3 is assembled to the connector body 1 by press-fitting the retainer 4 to which the retainer 3 is fixed from the back of the connector body 1.

The releaser 5 includes a cylindrical sliding portion 5a that slides around the cable 7, and a hook-shaped operating portion 5b for operating the sliding portion 5a provided at the rear portion thereof. The sliding portion 5a has a length that reaches the retainer 3 from the back of the fixed sleeve 14, and the tip is in contact with the claw portion 3a of the retainer 3 as shown in the enlarged view of part A of FIG. The joint portion 5d is formed with a tapered surface and a sharp tip.

There is no.
The operation portion 5b is disposed behind the connector body 1, and the operation portion 5b is operated and pressed forward to slide the slide portion 5a, and the tip operation portion 5d pushes the claw portion 3a forward. . As a result, the diameter of the claw portion 3a is increased and the claw portion 3a is lifted from the cable 7. In this way, the cable 7 holding action by the stopper 3 is released, that is, the removal preventing action is released.

Next, the procedure for assembling the connector and attaching it to the cable will be described. In assembling the connector, first, an annular connecting portion 10 having a sleeve body 6 is inserted into and connected to the connector body 1 from the rear. At this time, the annular connecting portion 10 is fixed and integrated by press fitting or the like. And after fitting the nut body 2 to the cylindrical fitting part 8, the nut part 2 is rotatably connected to the connector main body 1 by expanding the diameter of the fitting part 8.
Thereafter, as described above, the retainer 3 held and fixed by the fixing sleeve 14 and the fixing ring 15 is inserted into the connector body 1, the retainer 3 is attached, and the releaser 5 is inserted to complete the connector. To do.

The mounting operation of the cable 7 is performed as follows. The end of the cable 7 to be inserted first is processed. Specifically, as shown in FIG. 1 (or FIG. 4 described later), the inner insulator 7b and the protective coating 7d are cut out so that the center conductor 7a and the inner insulator 7b are exposed to a predetermined length, The conductor 7c is rolled up on the protective coating 7d. Thereafter, the cable 7 may be inserted into the connector body 1 from the rear.
FIG. 4 is a side explanatory view showing a state before the cable is inserted, and FIG. 5 is a side explanatory view showing the state in the middle of the cable insertion. FIG. The cable 7 is inserted up to a predetermined position where the protective coating 7d contacts the back of the front surface of the connector main body 1, more precisely, the annular connecting portion 10. By doing so, the sleeve body 6 is inserted between the inner insulator 7b and the outer conductor 7c, and the outer conductor 7c and the connector body 1 are reliably electrically connected via the sleeve body 6. Due to the action of the band-like protrusions 11 formed around the body 6, the cable 7 does not easily rotate even when rotational stress is applied, and a good connection state can be maintained.
And the nail | claw part 3a acts so that the cable 7 may be pinched reliably as mentioned above. Furthermore, the tip of the center conductor 7a protrudes to the tip of the nut body 2, and the center conductor of the cable 7 is disposed on the center axis (M) of the nut body 2 to obtain the center conductor of the connecting means.

In FIGS. 4 and 5, 7e indicates an aluminum foil. The outer conductor of the coaxial cable is generally composed of a net-like conductor (the outer conductor 7c described above) and an aluminum foil 7e provided on the inner side thereof. At the time of partial processing, the sleeve body 6 is inserted between the aluminum foil 7e and the net-like conductor (the above-described external conductor 7c) while keeping the aluminum foil 7e along the inner insulator 7b without turning.

As described above, the coaxial cable attached to the connector does not come off even when a tensile stress is applied due to the action of the stopper, and can be firmly attached. Nevertheless, by operating the releaser, it is possible to easily remove it by releasing the removal preventing action by the retainer, so that work such as cable replacement can be easily performed. Furthermore, if the end portion of the coaxial cable is processed into a predetermined shape and inserted into the connector body 1, the connector mounting is completed and the connector portion is completed, so that the connector mounting is easy. Also, since the removed connector can be reused, there is no waste.
Further, the retainer can smoothly insert the cable, and can prevent rotation of the attached cable without providing a separate rotation prevention means by the band-shaped protrusion formed on the sleeve body, and can maintain a good connection state.
Furthermore, the releaser has a simple structure and shape, does not complicate the connector configuration, and can be connected to a receptacle terminal of an electronic device or the like by using a connecting means as a plug.

Next, a second embodiment of the connector according to the present invention will be described with reference to FIGS. FIGS. 6 and 7 are side views of the connector with the main part shown in cross section. FIG. 6 shows a state where a coaxial cable is connected, and FIG. 7 shows a state before the coaxial cable is connected. The difference from FIG. 1 is that a dedicated locking body 17 is provided as a rotation preventing means in the connector body 1, FIG. 8 shows the locking body 17, and FIG. Side view, (b) shows a front view of the locking body. In addition, the same code | symbol is provided to the structural member similar to the said FIG. 1, and description is abbreviate | omitted.
Hereinafter, the locking body 17 will be described. As shown in FIG. 7, the locking body 17 is formed in a cylindrical shape having the same length as the sleeve body 6. Then, as shown in FIG. 8, the slit 17a is provided so that the diameter can be changed, and the whole is formed to have elasticity in the radial direction using stainless steel for springs. Is formed.

Reference numeral 17b denotes an opening punched out to form the locking blade 18. The locking blade 18 is formed to be bent inward on one side of the opening 17b, and is a connector central axis M as a central axis. It is formed in a strip shape in parallel with. Further, the front end portion that bites into the coaxial cable 7 is formed at an acute angle when punching out, so that the tip portion can easily bite into the protective coating 7 d of the coaxial cable 7. Further, the amount of protrusion of the locking blade 18 is set so that the gap between the sleeve body 6 when assembled to the connector body 1 is a predetermined amount smaller than the thickness of the protective coating 7d of the coaxial cable 7 to be inserted. However, the rear end portion 17c on the coaxial cable 7 insertion side is expanded so that the coaxial cable 7 can be easily inserted.

Inserted.
Thus, the coaxial cable inserted by the locking body does not rotate. In particular, by disposing the locking body so as to cover the sleeve body, the coaxial body insertion operation causes the sleeve body to enter between the inner insulator and the outer conductor, and the protective coating rises around the sleeve body. , The locking blade securely bites into the protective coating. Therefore, the rotation of the coaxial cable can be reliably prevented. Further, since the latching body has elasticity, the protective covering is sandwiched between the sleeve body 6 from the inside and the latching body 17 from the outside, and the holding force is greater than that of the first embodiment. In addition to the improvement, even if the protective coating of the coaxial cable is plastically deformed due to aging, the rotation prevention function of the coaxial cable can be maintained.

In each of the above embodiments, the rotation-preventing means is provided as the belt-like protrusion 11 provided on the sleeve body.
