DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a first embodiment of a connector for a coaxial cable (hereinafter simply referred to as a connector) according to the present invention, an explanatory view showing the main part of the connector mounted on the coaxial cable 7 in section, and A partially enlarged view is shown.
In FIG. 1, reference numeral 1 denotes a cable mounting means inside, a cylindrical connector body that is externally fitted to a coaxial cable (hereinafter simply referred to as a cable), and 2 a nut as a connection means for connecting to a connection object such as a receptacle. Is the body. The cable mounting means includes a retainer 3 for preventing the attached cable from being pulled out, a fixing member 4 for fixing the retainer 3, a releaser 5 for releasing the retaining action of the retainer 3, and an internal insulation of the cable 7 to be mounted. It consists of a sleeve body 6 inserted between the body 7b and the outer conductor 7c, and will be described below with the left direction in the figure as the front. Reference numeral 7a denotes a central conductor of the cable, and 7d denotes a protective coating.

The connector main body 1 has a cable insertion port at the rear, and a small-diameter cylindrical fitting portion 8 for attaching the nut body 2 to the front is formed to protrude, and the cable 7 to be attached is attached to the cylindrical fitting portion 8. An insertion hole 8a is formed through which the internal insulator 7b and the central conductor 7a are inserted. The nut body 2 is internally threaded, 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 to the front surface of the connector body 1. Yes. The cylindrical fitting portion 8 is expanded in diameter at the tip after fitting with the nut body 2, and the nut body 2 does not fall off.

FIG. 2 shows a perspective view of the sleeve body 6 as seen from the rear. As shown in FIG. 2, the sleeve body 6 is integrally formed on the back portion of the annular connecting portion 10 for connecting to the connector main body 1, and is formed in a conical shape with a gradually decreasing thickness and a thin tip at the rear end portion. ing. However, the insertion hole 6a is formed with the same diameter. This facilitates insertion between the inner insulator 7b and the outer conductor 7c of the cable 7.
A plurality of linear band-like protrusions 11 as rotation preventing means are formed on the side surface of the sleeve body 6 from the annular connecting portion 10 to the rear end portion. 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 present invention is not particularly limited to the embodiment, for example, knurling may be used instead of the belt-like protrusions.
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.

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 includes a ring-shaped locking portion 3b having the same central axis as the central axis of the connector body 1, and an inner side of the ring-shaped locking portion 3b directed toward the center line of the locking portion 3b. And a plurality of claw portions 3a projecting.
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. It may be formed by providing a radius that matches the diameter of the cable, and is not particularly limited, and may have an optimum shape for a predetermined holding force required to hold the cable.

Further, as shown in the end view of the line BB in FIG. 3 (b), the claw portion 3a is formed to be bent in the inner direction of the connector body 1 at the front of the connector with a bending angle θ of about 45 °, for example. The stopper 3 as a whole may have a substantially conical shape constricted forward.
By bending in this way, the diameter of the claw portion 3a is easily expanded during the cable insertion operation, so that the insertion operation can be carried out smoothly. Even if it is formed in this way, when a tensile stress is applied to the inserted cable, the claw portion 3a surely bites into the cable, so that it does not fall out.
Further, the locking portion 3b of the retainer 3 is formed with a predetermined plane portion in the outer peripheral direction, and the fixing member 4 of the retainer 3 is disposed inside the connector body 1 in which the plane portion 3b is disposed. Since the stepped portion 14a of the fixing sleeve 14 and the end face of the fixing ring 15 are formed so that the movement of the locking portion 3b in the front-rear direction is limited, Since the stop portion 3b does not warp in the forward or backward direction, the locking portion 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. .
In addition, when the locking portion 3b is sandwiched between the step portion 14a of the fixing sleeve 14 and the end surface of the fixing ring 15, the fixing sleeve and the fixing ring are fixed so that they are in close contact with each other, thereby This not only restricts the movement in the front-rear direction, but also prevents the retainer from rotating, and is not only strong against the pulling force against the coaxial cable but also against the rotational force applied to the coaxial cable. Highly reliable mounting.

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 has a substantially cylindrical shape that slides around the cable 7, and as shown in FIG. 6, the first sliding portion 51a and the second sliding portion whose outer shape is halved in the central axis direction. The sliding part 51 which consists of the moving part 51b is comprised, both are connected by the two hinge-shaped connection parts 53 formed continuously, and are integrally formed with the synthetic resin. At the rear part of the sliding part 51, a hook-like operation part 55 for operating the sliding part 51 is formed integrally with the sliding part 51. As described above, since the first sliding portion 51a and the second sliding portion 51b are integrally formed via the hinge-like connecting portion 53, the assembly operation is performed by bending the hinge-like connecting portion 53 to be the first. It is only necessary to match the sliding portion 51a and the second sliding portion 51b, and there is no operation to join a plurality of members. Therefore, it can be set in a connector before the coaxial cable is attached, Even after the coaxial cable is mounted, it can be easily mounted so as to slide around the coaxial cable 7.
In addition, as a material of the synthetic resin, polyethylene or polypropylene which is relatively flexible and easily forms a hinge-like connecting portion is suitable.

Since the outer diameter of the sliding portion 51 is formed so as to be slightly smaller than the inner diameter of the releaser insertion portion 14b when attached to the cable 7, the sliding portion 51 is fixed while sliding around the cable 7. The sleeve 14 is inserted into the releaser insertion hole 14b. The sliding portion 51 has a length that reaches the stopper 3 from the back of the fixed sleeve 14, and the tip abuts against the claw portion 3a of the stopper 3 as shown in the enlarged view of part A of FIG. The engaging portion 5d is formed with a tapered surface and a sharp tip. A step portion 5c is formed on the outer periphery of the sliding portion 51 so as to be engaged with a locking protrusion 14c formed on the releaser insertion portion 14b of the fixed sleeve 14, and the sliding portion 51 is connected to the hinge-like connecting portion 53. Therefore, the force that the first sliding portion and the second sliding portion try to open outwardly acts, and as a result, the releaser 5 inserted into the releaser insertion portion 14 has a force. The step portion 5c is fitted with the locking projection 14c and temporarily fixed so as not to easily fall.
Further, since the operation unit 55 is disposed behind the connector main body 1, when the operation unit 55 is operated and pressed forward, the sliding unit 51 slides, and the tip operation unit 5d is moved to the claw portion 3a. Press 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 and the retainer 3 is mounted, and the connector is completed. The connector thus completed may or may not have the releaser 5 attached to the fixed sleeve 14 in advance.
In the embodiment of the present invention, the connecting means 2 is shown as being pivotally attached to the cylindrical fitting portion 8 formed in the connector body 1. However, the cylindrical fitting portion is provided on the front side of the sleeve body 6. It may be provided and configured to be pivotally attached to the cylindrical fitting portion.

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 inside thereof. At the time of end processing, the sleeve body 6 is inserted between the aluminum foil 7e and the net-like conductor (the above-described external conductor 7c) while the aluminum foil 7e is not stretched and is kept along the inner insulator 7b.

As described above, the coaxial cable attached to the connector does not come off even when a tensile stress is applied by the action of the stopper 3 and can be firmly attached. Nevertheless, by operating the releaser 5, the removal preventing action by the retainer 3 can be released and easily removed, so that work such as cable replacement can be easily performed. Further, if the end portion of the coaxial cable is processed into a predetermined shape and inserted into the connector body, 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.
Furthermore, since the releaser 5 according to the present invention is formed integrally with the sliding portions 51a and 51b connected via the hinge-like connecting portion 53, the assembling work is a bending operation centered on the hinge-like connecting portion 53. Can be assembled easily. In addition, with this configuration, even after the coaxial cable 7 is attached to the connector, it can be easily slidably mounted around the coaxial cable, so there is a change in wiring and a mistake in the coaxial cable installation. Even if this happens, the coaxial cable can be removed.
Furthermore, since the releaser can be installed even after the cable is installed, the releaser can be temporarily attached to the connector in advance, or shipped separately as an accessory. In case of shipping as a low-priced bulk product, it can be purchased separately as a single unit, so that it can be handled by a general user or by a contractor. It is possible to provide an electronic device equipped with a coaxial cable connector and a coaxial cable connector represented by a branch / distributor.

Note that the present invention is not limited to the above-described embodiment, and the configuration of each part can be appropriately changed and implemented without departing from the spirit of the present invention.
