Description

Cable

Technical field

The present invention relates to for example be used for the cable of power line and various holding wires etc., specifically, relate to the cable that is easy to determine off-position and the easy differentiation in cut-out back residue length.

Background technology

The various cables of electric wire and various holding wires etc. for example generally dispatch from the factory with the state that is wound on spool etc., extract out to cut off after the necessary length and use.These cables are also given the consumer in general snacks shop direct marketing except business is used.

Usually, when selling on a small quantity, often use ruler to measure to cut off behind the cable of consumer's amount of ordering and sell.But this method is cut off sale owing to will measure the back at every turn, cost formality and time.

Thereby, for example, the part of the cable shown in the patent documentation 1 (the open H11-306874 communique of Japan's special permission) has been proposed.As shown in Figure 4, the surface of this cable 1 is provided with mark 2 every one meter.The length mark 2b of position mark 2a that mark 2 is formed by wire and the record adjacent with the position mark 2a length till from beginning of cable 1 to position mark 2a forms.

Thereby, used how many cables to come into plain view up to now.Thereby, cut off cable by utilizing this mark 2, can not use ruler ground to cut off the cable of certain-length.

But this mark 2 is arranged for judgement from the length that beginning of cable 1 begins, and can produce following problem when above-mentioned cut-out is sold.That is, former cable serves as zero with the top of cable, increase gradually along the order numeral of end side according to 1m, 2m, 3m..., thereby, can't correctly hold cable and also what remain.

Thereby the snacks shop is carried out stock control or when making an inventory etc., can only be used the remaining cable length of hand measurement, or deduct the length that shows as length mark 2b and calculate remaining cable length from all cable length, and the result spends formality and time.Equally, when inquiring the stock, the consumer can't answer at once, and very inconvenient.

And each mark 2 only is arranged on a place, if the left side at for example position mark 2a cuts off cable 1 among Fig. 4, does not then have mark 2 at the top of residue cable, thereby when follow-up cut-out, may feel uneasy to whether having carried out cut-out in definite position before.

Summary of the invention

Thereby the present invention is in view of solving above-mentioned problem, and purpose provides not only can simply judge residue length, and the cable that can quantitatively cut off reliably.

In order to reach above-mentioned purpose, the present invention possesses the feature of the following stated.Be provided with at certain intervals along its length in the cable of the cut-out mark that cuts off usefulness at outer surface, it is characterized in that, the above-mentioned mark that respectively cuts off is arranged to the cut-out datum mark of the above-mentioned cable of clamping and is possessed Rack in the longitudinal direction.

Thereby, cut-out datum mark by being arranged to the clamping cable and possess symmetrical Rack cuts off cable cutting off datum mark, thereby, the two ends of the cable that cuts off all remain a part of cutting off mark, can easily differentiate near cutting off datum mark and cut off cable reliably.

As better form, above-mentioned cut-out mark preferably is made up of a pair of cut-out aid mark that with above-mentioned cut-out datum mark is the configuration of center and the left-right symmetric that possesses Rack.Thereby, by between the cut-out aid mark, cutting off cable, can stay the cut-out aid mark, can determine off-position simply.

As other forms, above-mentioned cut-out mark also can be made of 1 thick line that waits width that with above-mentioned cut-out datum mark is the center.Thereby,, can easily carry out determining of off-position by being 1 thick line at center to cut off datum mark.

As better form, the width of above-mentioned cut-out mark is preferably 1mm～10mm.Thereby, can stay the cut-out mark reliably at the two ends of the cable that cuts off.

That is, cut off mark width if not enough 1mm less than, be difficult to when then cutting off judge whether cut off aid mark can stay.On the contrary, width then is difficult to determine to cut off datum mark if surpass 10mm, and it is big that the error of shearing length becomes.

In addition, be preferably in above-mentioned respectively the cut-out surplus mark of demonstration from beginning of above-mentioned cable to the residue length of terminal also is set in the mark.Thereby,, can judge the residue length of cable by in cutting off mark, the surplus mark being set at a glance.

As better form, above-mentioned surplus mark preferably is arranged to the symmetrical a pair of of the above-mentioned cut-out mark of clamping.Thereby, stay the surplus mark at the two ends of the cable that cuts off, thereby can easily differentiate and whether cut off in the tram.

Embodiment

Then, with reference to drawing explanation embodiments of the invention.Fig. 1 is the perspective view and the part enlarged drawing of the cable of one embodiment of the invention.Fig. 2 be cable want portion's enlarged drawing.In addition, the invention is not restricted to this embodiment.

Among the present invention, cable is meant the wire rod with the crust lining such as the heart yearn of for example electric wire and various holding wires etc., more particularly, except sound equipment with various line cables, speaker cables, vision cable, various feed cable, digital audio cable, the optical cable, also comprise various electric wiring classes of automobile etc. etc.In addition, the essential structure of cable and internal structure are arbitrarily.

This cable 10 has not shown heart yearn in inside, by the lining cable of heart yearn with plastic crust lining constituted, with the state keeping of winding reel R.In addition, among this embodiment, cable 10 is the state of winding reel R, but not necessarily must be with the state keeping of winding reel R.

At the outer surface of cable 10, with predetermined distance L the cut-out mark 20 that cuts off usefulness is set along its length, in this example 1 meter interval.50 centimetres or 20 centimetres etc. also can be suitably set in the demonstration of this cut-out mark 20 at interval for.In addition, except cut-out mark 20 of the present invention, also can print electric capacity, the manufacturing model of lining material and power line, the various information of goods name etc. in the cable 10.

Cut off mark 20 and show with predetermined distance, as the part enlarged drawing of Fig. 1 and shown in Figure 2, each cuts off mark 20 and comprises along a pair of cut-out aid mark 21,22 with Rack x and subtend configuration of the length direction of cable 10.

In this example, each width x that cuts off 21,22 of aid marks is 4mm, cut off aid mark 21,22 be preferably disposed on the cut-out datum mark P that shows by rice be the center etc. on the position of width.In addition, each cuts off 21,22 of aid marks the 3rd aid mark that datum mark P is cut off in expression also can be set.

In this example, the width x that cuts off aid mark 21,22 sets 4mm for, is preferably in the above 10mm of 1mm following (and it is following to be preferably in the above 8mm of 3mm).That is, width x if not enough 1mm less than, then during cable cutting, be difficult to judge whether cut off aid mark can stay.On the contrary, width x then is difficult to determine to cut off datum mark P if surpass 10mm, and shearing length might produce error.

Each cuts off aid mark the 21, the 22nd, is disposed in parallel to each other by straight line with the length direction quadrature of cable 10 to form, in addition, also can be point-like or shape of stripes etc., be configured to a pair ofly that its shape can be arbitrarily as long as can cut off aid marks 21,22 with 2.

And cutting off mark 2 and can be to cut off datum mark P be that the center possesses Rack, and example also can be to be the wide thick line of wide width at center to cut off datum mark P as shown in Figure 3A.That is, in this cable 10, form by the rectangular-shaped cut-out mark 20 that possesses Rack x (width x is 4mm in this example) in the longitudinal direction.In addition, line width x also is preferably in the above 10mm of 1mm following (and it is following to be preferably in the above 8mm of 3mm).

Thereby at the two ends of the cable 10 that cuts off, whether the part of thick line by remaining cut-out aid mark 21,22, can be judged at a glance and cut off at the assigned position of allowing during by severing.

In addition, as additive method, shown in Fig. 3 B, also have not to be with thick line but to form the method for cutting off mark 20 with rhombus.Thereby, can cut off cable 10 in more accurate position with the diagonal of rhombus as imaginary cut-out datum line P.

Referring again to Fig. 2, cut off and to be provided with surplus mark a, a that has put down in writing from the beginning 1a of cable to the residue length of terminal in the mark 20.Surplus mark a, a are arranged to adjacent with each cut-out aid mark 21,22 respectively, and be more little the closer to end side numerical value.Among Fig. 2, dispose surplus mark a respectively on the right side of left side that cuts off aid mark 21 and cut-out aid mark 22.

Thereby, cut off cable 10 by the space (serving as 33 meters of residue in this example) that cuts off 21,22 of aid marks with each as cutting off datum mark, owing to stay cut-out aid mark 22 and a surplus mark a at the end of this cable 10 10a, not only can easily judge the residue length of cable 10, and can understand by cutting off aid mark 22 and cut off cable 10 in the permissible range position of regulation.

Equally, owing to also stay cut-out aid mark 21 and another surplus mark a at the end 10b of the cable 10 that cuts off side (being the left side among Fig. 2), thereby can easily differentiate in regulation permissible range position and cut off.In addition, owing to the surplus mark a that has stayed in the end of not shown opposition side when last time cutting off, thereby can obtain from the total length of the cable 10 that cuts off here.

Among this embodiment, the surface printing that cuts off mark 20 and surplus mark a, a and be at cable 10 forms, but, for example also can prepare cable 10 respectively and record the strip of paper used for sealing that cuts off mark 20 and residue mark a, a, strip of paper used for sealing is pasted on the cable 10 with predetermined distance, and these various variation also are that the present invention comprises.
