[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamper for a cable, which is fixed to an end of a bundle of a plurality of wires.

[0002]

2. Description of the Related Art Conventionally, a clamper fitting of this kind of cable is
A ring-shaped member made of a copper alloy or an aluminum alloy is generally used. When this ring-shaped clamper is fixed to an end of a cable, for example, as shown in FIGS. After the end of the cable 12 is inserted through the cable, the outer periphery of the ring 11 is crushed by caulking of the exclusive presses 13a and 13b so that the core wire 12a is not broken.
1a is formed, and the protrusion 11a serves as a stopper and a stopper when the cable 12 is attached to a connector or the like.

[0003]

[Problems to be Solved by the Invention] However, when the conventional ring-shaped clamper is fixed to the end of the cable, it takes time to pass the ends of the cable one by one through the ring, and the cable is required for mass production. It is necessary to determine the position and height of the caulking jig according to the number of core wires and the diameter of the jig, and set the jig in a dedicated press machine. Also, if the ring according to the thickness of the cable is not properly selected, the core wire may be broken by caulking work.Therefore, prepare a large number of ring-shaped clamper fittings corresponding to the thickness of the cable. There is a problem that inventory management is troublesome and cost increases.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems, and to provide a clamper fitting for an electric cable in which a clamper formed by pressing a steel plate material can be more easily fixed around the end of the cable. To get.

[0005]

In order to achieve this object, a clamper for a cable according to the present invention is provided with a plurality of cable restraining pieces alternately protruding on the left and right sides of the cable holding section. Pressing the clamper metal with the anti-rotation pieces protruding to the left and right by stamping steel plate material, bending the central part of the cable holding part of the clamper metal into a U shape, and raising the cable restraining pieces to the left and right, The right and left detent pieces are bent outward, and a mountain-shaped bead portion for pushing the side surface of the cable is protruded inward at the center of the cable holding portion.

[0006]

In the clamper of the present invention, the end of a predetermined cable is set in the U-shaped cable holding portion of the clamper, and the cable holding pieces raised on the left and right of the cable holding portion are set. The cable is bent from the left and right sides and wrapped around the outer periphery of the cable, and a part of the cable is bent by the bead portion of the cable holder, so that the clamper can be fixed so as not to come off from the cable end. Therefore, it is not necessary to prepare a clamper fitting corresponding to the thickness of the cable, and mass production can be performed without fear that the core wire is broken during the caulking operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a top view showing a state in which a clamper of an electric cable according to the present invention is press-formed, and FIG. 2 is a development view of the clamper which is stamped from a steel plate by pressing. In the figure, reference numeral 1 denotes a steel plate material having an appropriate strength, and reference numeral 2 denotes a clamper metal stamped from the steel plate material 1 by press working in a first step. A large number of the clamper fittings 2 are formed in a chain on the carrier portion 1a left on one end side of the steel sheet material 1.

[0009] The clamper fitting 2 is firstly moved from the steel plate material 1.
As shown in FIG. 2, a plurality of cable restraining pieces 4 are alternately provided on the left and right sides of the cable holding section 3 while being punched out by the press working in the process. The anti-rotation piece 5 is protruded. A bent piece 4a bent slightly inward is formed at the front end of the cable holding piece 4 and a thin reinforcing bead 6 is attached to the cable holding piece 4 from the cable holding section 3.
Are formed so as to protrude from the upper surface in the figure.

Further, as shown in FIG. 1, FIG. 3, and FIG. 4, the clamper fitting 2 punched by the press working in the first step is used to press the cable holding part 3 by the press forming in the second step.
The central part of the cable is bent into a U-shape, and the cable restraining pieces
And the left and right detent pieces 5 are bent outward. At the same time, the cable holder 3 is bent in a U-shape during the press forming in the second step, and the cable holder 3 is simultaneously bent.
A mountain-shaped bead portion 7 for pushing the side surface of the cable is protruded inward at the center of the cable.

Next, a description will be given of a case where the clamper 2 is fixed to the end of the cable 10 based on the embodiment of the present invention configured as described above. First, as shown in FIG. 4, an end of a predetermined cable 10 is set in a cable holding portion 3 of the clamper 2 which is curved in a U-shape. Then, the cable holding pieces 4, 4 raised to the left and right of the cable holding section 3 are bent from the left and right sides so that the bent pieces 4 a bite into the cable 10, and as shown in FIGS. And wrap it around the outer periphery. At this time, a part of the cable 10 is bent so that the bead portion 7 of the cable holding portion 3 bites, so that the clamper 2 can be fixed to the end of the cable 10 without coming off. Further, after the clamper fitting 2 is fixed to the end of the cable 10, the carrier 1 a in which a large number of the clamper fittings 2 are formed in a chain is sequentially moved to fix the clamper fitting 2 to the end of the cable 10. Can be performed continuously. In addition,
The operation of fixing the clamper fitting 2 to the electric cable 10 can be performed continuously by moving the clamper fitting 2 by a plurality of pieces. After the clamper 2 is fixed to the end of the cable 10, the clamper 2 is cut from the carrier 1a.

FIG. 7 is a sectional view showing a state in which the cable 10 to which the clamper fitting 2 according to the present invention is fixed is attached to the connector case 8 or the like.
The locking piece 5 is locked on the side wall of the fitting portion 8a of the connector case 8, or fitted into a locking groove or the like (not shown) of the fitting portion 8a to stop the rotation.

[0013]

[Effect of the Invention] As described in detail above, the clamper fitting of the cable according to the present invention includes a plurality of cable restraining pieces that are alternately protruded on the left and right sides of the cable holding section, and the left and right of the middle of the cable holding section. The clamper bracket consisting of the protruding detent pieces is punched out of a steel plate, the central part of the cable holding part is bent into a U-shape, and the cable restraining pieces are raised to the left and right, and the left and right detent pieces are set outside. The bead is shaped like a ridge, and the mountain-shaped bead that pushes the side of the cable into the center of the cable holding part protrudes inward.It is applicable even if the thickness of the cable is slightly changed, Inventory management is easy. Also,
There is no need to determine the position and height of the caulking jig according to the number and diameter of the core wires of the cable, or to set up the end of the cable through the clamper metal fittings. Since mass production is possible without worrying that the core wire is broken during the operation, a significant cost reduction can be achieved.
