Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a coaxial cable stripper, and in particular, in order to connect a coaxial cable to another device, the coating at the cable end is removed by a specified size. The present invention relates to a coaxial cable stripper used for

[Prior Art] Conventionally, a coaxial cable stripper has been used to treat a coating 100A at a terminal portion of a coated cable 100 as shown in Fig. 4A as shown in Fig. 4B. 5A
FIG. 5 and FIG. 5B show in principle an example of a conventional commercially available coaxial cable stripper. The stripper 101 of this example is composed of both a male member 102 and a female member 103 whose cable holding portions mesh with each other, and 102A denotes a male member 102.
The cable holding portion 103 A is a cable holding portion of the female member 103. Further, 102B is a blade for cutting the coating attached to the male member 102, and 103B is a blade attached to the female member 103.

Therefore, in the stripper 101 configured as described above, the fifth
As shown in FIG. A, a facing force in the direction of arrow A is applied to both the male member 102 and the female member 103, and as shown in FIG. 5B, both cable holding portions 102A and 103A are kept in a superposed state, The covered cable 100 is held between them. Thus, both blades 102B and 103B are made to bite into the covering portion 100A of the covered cable 100, and the entire stripper 101 is rotated around the covered cable 100 as shown by an arrow B to remove the covered portion 100A. A notch can be formed at the boundary between the to-be-processed part and the subsequent part.

Therefore, thereafter, for example, by operating the stripper 101 in a direction perpendicular to the paper surface while holding the coated cable 100, the coated portion 100A at the tip can be removed by pulling it out. When removing the coating laminated in multiple stages, the cable holders 102A and 103A
The diameter and depth of the blades and the relative positions of the blades 102B and 103B are different from each other in the cable holding portion which is formed by changing the cut position of the cable, and then the same operation is sequentially repeated. The state shown in (B) can be set.

6A and 6B show another conventional example. This example is also another example of a coaxial cable stripper that is generally commercially available, and its principle configuration is shown. In these drawings, 201 is a stripper, 202 is a main body member thereof, 203 is an actuating member which is combined with the main body member 202 and operates in the direction of arrow C, and 202A and 203A are respective cable holding portions. In the case of this example, the blade 202B is attached only to the side of the main body member 202, and the blade 202B is composed of a plurality of blades that are arranged at a predetermined interval in a direction perpendicular to the paper surface.

Further, the degree of cutting edge of the blades 202B (only one of which is shown here) in the cable holding portion 202A is changed for each blade, and as shown in FIG. When the cable 100 is held between the operating member 203 and the operating member 203, the cutting amount is different for each blade, and the cable 100 is deeply cut as it goes to the tip portion.

Therefore, in the stripper 201 configured as described above, the portion to be processed of the coated cable 100 is positioned on the cable holding portion 202A of the main body member 202, and the force in the direction of arrow C is applied to the actuating member 203 to generate the sixth portion 6B. Blade 20 as shown
By making a cut in the cable covering 100A by 2B and subsequently rotating the entire stripper 201 in the direction of arrow D, a cuttable cut can be made in the covering 100A. Therefore, after that, the cut-off covering portion may be pulled out from the cable 100.

[Problems to be solved by the invention] However, in the conventional coaxial cable stripper as described above, in both cases, relative cutting is always performed at the same position of the blade, so stress is concentrated on the blade edge and the blade is chipped. ,
That is, blade spillage is likely to occur. In addition, since there is a slight difference in the coating thickness of the cable depending on the manufacturer, it is difficult to adjust the depth of cut, and the cable is clamped between the cable holding portions separated over the two members. A slight deviation occurs in the cutting method due to the holding amount.

The stripper 101 shown in particular by Figures 5A and 5B.
In this case, since it is not configured to perform the stepwise cutting of the coating at multiple points at one time, it is necessary to adjust the specified length along the cable to be cut at each time, which is troublesome. It takes.

The purpose of the present invention is to focus on the above-mentioned conventional problems,
In order to solve the problem, it is an object of the present invention to provide a coaxial cable stripper which can surely and accurately process the covering portion of a terminal without causing a blade spill.

[Means for Solving the Problems] In order to achieve such an object, the present invention has a blade for forming a notch in a covering portion along a circumferential direction of a coaxial cable, and a notch formed by the blade. A coaxial cable stripper capable of removing the coating along the strip, a rotatable circular blade, a cable holding portion for holding the coaxial cable, and means for press-contacting the circular blade to the coaxial cable held by the cable holding portion. It is characterized in that a circular blade is rolled along the circumference of the coaxial cable to perform push-cutting.

[Operation] According to the present invention, first, the depth of the cutting edge inserted into the cable holding portion through the slit is adjusted to a predetermined amount by the cutting depth adjusting means, and then the coaxial cable is inserted into the cable holding portion. It keeps the cutting edge of the circular blade in the cover of the cable via the pressure contact means, and rolls the circular blade around the cable to push it off.By using the blade edge of the circular blade evenly, It is possible to suppress blade spillage and abrasion as in the past.

[Embodiment] An embodiment of the present invention will be specifically described below with reference to the drawings.

1A to 1C show an embodiment of the present invention. In these drawings, 1 is a stripper thereof, 2 and 3 are main members and actuating members constituting the stripper 1 , 4 is a support pin for swingably supporting the actuating member 3 with respect to the main member 2, and 5 is a main member. The compression spring is interposed between the protrusion 2A of the second member 2 and the protrusion 3A of the actuating member 3. Reference numeral 6 denotes a cable holding tube provided so as to penetrate the main body member 2, and the cable holding tube 6 has a plurality of slits (3 rows in this example) 7A to 7C are shown in FIG. 1B or FIG. 1C. Is cut like this. Reference numeral 8 denotes an operation hole which is provided at an end of the main body member 2 so that a human finger can be inserted to perform a covering portion cutting process described later.

9A to 9C are circular blades provided on the actuating member 3 and rotatably supported around the support shaft 10. The circular blades have different radii, and the circular blades are arranged so as to keep a predetermined interval. As a result, the cutting edges of the blades 9A to 9C are kept inserted into the slits 7A to 7C provided at the corresponding positions as shown in FIG. 1B. Reference numeral 11 denotes a blade tip adjusting device attached to the operating member 3, and includes a boss 11A with a screw hole fixed to the operating member 3 and an adjusting screw screwed into the screw hole of the boss 11A.
11B and the tip portion 11C of the adjusting screw 11B by rotating the adjusting screw 11B with a screwdriver or the like.
Abutting on the outer circumference of the cable holding tube 6, and thus the circular blade 9A
It is possible to adjust the depth of cut of the cable covering portion 100A by 9C. Reference numeral 12 is a handle provided on one end of the operating member 3.

In the state before the operation of the coaxial cable stripper 1 configured in this way, as shown in FIG.
Since the actuating member 3 is biased by the spring force to rotate around the support pin 4 in the counterclockwise direction,
The tip portion 11C of the adjusting screw is kept in contact with the outer peripheral portion of the cable holding tube 6.

Therefore, when the terminal treatment of the cable 100 is performed, first, the slits of the circular blades 9A to 9C are cut by the cutting edge adjusting device 11.
After adjusting the depth to be inserted into the cable holding pipe 6 via 7A to 7C, press the handhold 12 and hold the cutting edge of each circular blade 9A to 9C as shown in FIG. The cable 100 may be inserted into the holding tube 6 and positioned at a predetermined position where a cut is made, without being pulled away from the inside.

The principle of the terminal processing operation thereafter will be described with reference to FIGS. 3A and 3B. That is, FIG. 3A is a principle view corresponding to FIG. 2 shown above, and in this state, by releasing the hand from the hand-holding portion 12 shown in FIG. It can be rotated to the state shown in FIG. 3B. At this time, after the circular blades 9A to 9C contact the outer peripheral portion of the cable 100, the circular blades 9A to 9C rotate by themselves in accordance with the above-described rotation, and bite into the cable covering portion 100A in a push-cut state, The state shown in FIG. 3B is obtained.

Therefore, after this, it is sufficient to rotate the entire stripper 1 in the direction of the arrow F around it while holding the cable 100 firmly. With the above operation, in the case of this example, the predetermined intervals are maintained at three positions. Since it is possible to form notches with different depths in the cable, either pull out the cable 100 from the holding tube 6 after that, or return it to the state shown in Fig. 3A and pull out the cable 100 by hand. It is sufficient to remove the coating portion 100A in which the notch is formed.

[Advantage of the Invention] As described above, according to the present invention, a rotatable circular blade, a coaxial cable can be inserted, a cable holding portion having a circumferential slit at a predetermined position, and a cable. The coaxial cable inserted into the holding part is equipped with pressure contact means for cutting the blade edge of the circular blade through the slit, and the coaxial cable held in the cable holding portion is cut into the circular blade edge. By rolling the circular blade along the circumference of the coaxial cable so that the incision is formed in the coating by the press cutting, the cutting edge of the entire circumference of the circular blade is used in the form of the press cutting. Not only can blade spillage and blade wear be suppressed, but the cable holding part and pressure contact means can securely hold the cable in place, and the cutting depth can be subtly delicate. It is possible to adjust the depth to a depth corresponding to the thickness of the covering portion which varies depending on the cable manufacturer.

In addition, in the above-described embodiment, the case of the stripper capable of forming the notches over three steps has been described, but it goes without saying that the number of such notches is not limited to three.
