Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a device for stripping an electric wire, and more particularly to a device for stripping an electric wire in which a plurality of insulating coating layers and shield layers are collectively stripped at respective stripping dimensions. It is.

[0002]

[Prior art]

 The conventional wire sheath stripping device consists of a pair of upper and lower semi-circular rotary cutter blades arranged at an interval from the covered wire insertion port and the insertion port, and the covered wire insertion port is formed to be movable back and forth. The upper and lower pair of semicircular cutter blades are formed so as to be able to expand and contract the blade diameter to a required diameter by matching with a guillotine blade shape. The stripping of the jacket layer is performed by moving the sheathed wire insertion slot to the distance from the rotary cutter blade according to the sheath stripping length using a scale juxtaposed to the slot, moving and fixing the sheathed wire, and inserting the sheathed wire through the insertion slot. In addition, the outer diameter of the jacket layer was cut off by adjusting the blade diameter of a pair of semicircular cutter blades to the peeling diameter of the covered wire, rotating the cutter blade, and pulling out the covered wire after stopping rotation.

[0003]

[Problems to be solved by the invention]

 In the case of the above-described conventional electric wire stripping apparatus, the stripping of the coating layer of the coated electric wire can be performed only for each of the coating layers, and the coating stripping process is performed only for each coated electric wire. Could not be done. In addition, since the distance between the jacket wire and the cutter blade is determined by the scale, the peel size of the jacket layer could not be set with high accuracy and was liable to vary. Further, the peeling device has a complicated structure and is expensive.

[0004] Therefore, an object of the present invention is to provide a simple and inexpensive wire sheath peeling device capable of peeling a multi-layered sheath layer of a covered wire with high precision at each peeling dimension.

[0005]

[Means for Solving the Problems]

 The wire sheath peeling device of the present invention is a wire sheath peeling device for peeling a terminal sheath of a covered wire to a required dimension, and is provided so as to be capable of opening and closing freely with a gap having substantially the same dimension as the outer diameter of the covered wire. A pair of covered electric wire holding bases, and a pair of the bases facing each other, which are perpendicular to the opposing board surface and are parallel to the required separation length of each of the separated covering layers in accordance with the number of peeling covering layers of the covered electric wires. A cutter blade mounted in each of the slits; cutter blade vertical movement means for finely adjusting a blade height of each of the cutter blades protruding from the opposing board surface of the pair of substrates to a required height; Pressing means for pressing the respective cutter blades from the back portion, the pair of bases are slidably fitted to each other in the longitudinal direction of the cutter blades, and a plurality of layers of the coated electric wire are peeled at a time. It is characterized by the following.

[0006]

[Action]

 In the electric wire stripping apparatus of the present invention, a slit corresponding to the number of stripping coating layers perpendicular to the opposing panel surface is provided on each of the opposing panel surfaces of the pair of covered electric wire holding bases that are openably and closably opposed. A layer is provided in parallel with the required separation length of the layer, and a cutter blade for separation is attached to each slit. Since each slit is pre-processed at an interval corresponding to the peel length of each outer layer, the interval between each slit can be set with extremely high precision in accordance with the peel size of each outer layer. Therefore, each covering layer can be accurately peeled at a required size. The cutter blades mounted on each slit are held by finely adjustable cutter blade vertical movement means and pressing means that constantly presses the cutter blade from the back. The blade height of the blade can be set accurately according to the thickness of each peeling outer layer, resulting in insufficient peeling due to insufficient cutting of the cutter blade in the outer layer and poor damage to the outer layer due to excessive cutting. There is no. As the cutter blade vertical movement means and the pressing means, for example, holes or cuts are provided at both ends in the longitudinal direction of the cutter blade, and a screw having a tapered tip is screwed into each of the holes or cuts. The height is finely adjusted to the required thickness of the peeling coating layer, and the tapered screw is used to support the cutter blade up and down, and the blade is always pressed by springs from the backs at both ends in the longitudinal direction of the cutter blade. Holding means. In the peeling process of the sheath layer using the wire sheath peeling device having such a configuration, a pair of covered wire holding bases are opened, the covered wire is placed on one of the bases, and the other base is placed on the outer diameter of the covered wire. The sheathed wire rotates on each cutter blade by sliding the pair of fitted bases relatively in the longitudinal direction of the cutter blade, so that each sheath layer of the sheathed wire is Is cut into a ring-shaped notch having a predetermined depth by a corresponding cutter blade. Thereafter, by pulling out the covered electric wire from the base, the respective jacket layers are collectively peeled at a predetermined peeling dimension.

[0007] In the above-described electric wire stripping apparatus, a slit and a cutter blade for cutting the coated electric wire are provided in addition to the slits and the cutter blades for the electric wire stripping, and the slit for cutting the coated electric wire is provided. If the slits for the sheath stripping are arranged in parallel to the required separation length intervals with the reference line as the reference line, the lead length of the core wire can be processed at the same time, so that the exact core lead length is required. It is convenient in the case.

[0008] In the above-described electric wire sheath peeling apparatus, if the base is formed so that it can be divided into a plurality of blocks at each slit, the cutter blade can be easily mounted on each slit and the thickness can be changed. The use of the prepared block makes it easy to cope with the case where the peeling length of the jacket layer is different, which is effective in improving the efficiency of the jacket peeling.

In the above wire stripping apparatus, if a comb-shaped guide for guiding a large number of covered wires is provided outside both sides of the pair of substrates in the placement direction of the covered wire, a large number of the covered wires can be numbered. Since the sheaths can be peeled all at once by arranging them on the base in order, there is no confusion in the wire number order of each coated wire even after the sheath is peeled. For example, when stripping a large number of insulated wires of a cable, if the insulated wires are arranged and placed on the substrate in the wire number order by the comb-shaped guide, the wire number order will not be incorrect. It is effective because the sheath can be peeled off, and the occurrence of wiring miss in the connection processing of the cable after the sheath is stripped is eliminated.
