Description

Area of utility model

The present utility model relates to a wire stripper.

Technical background

It is known from the prior art that wire strippers comprise a clamping part and a cutting part. When stripping a cable using stripping pliers, the cable sheath is clamped by the clamping part and cut off by the cutting part and then removed as a severed sheath piece, a notch produced by the clamping part remaining on the non-separated sheath. In this operating process, the clamping part is used to fasten and clamp the cable jacket and the cutting part is used to cut off the cable jacket and to remove the severed jacket section. For example from the Chinese Patent ZL200820134236.4 , the Chinese Patent specification ZL 200820137083.9 and the Chinese Patent ZL 201220255751.4 known wire strippers, the clamping part is arranged on the left side and the cutting part on the right side. When used as intended, the user holds the tool in his right hand and inserts the cable into the clamping part with his left hand, the cable then being moved from left to right until the point to be stripped is reached. Then the tool is squeezed together with the right hand in order to cut off the piece of jacket.

In addition, the guide ruler structure is provided in the right area of the wire stripper, which is also evidence of the cable movement from the left into the wire stripper. The guide ruler takes on the functions of guidance and distance measurement. In the revelations, for example, the Chinese Patent ZL 99208670.1 , the Chinese Patent specification ZL 200820137082.4 , the Chinese Patent specification ZL 201520842060.8 , the Chinese Patent ZL 201720198261.8 and the American U.S. Patent D771,458 S the guide ruler provided there is in the right area of the wire stripper.

All previously known wire strippers are designed in this way. The prior art is based on the design idea that to strip a cable with the aid of stripping pliers, a cutting process must be carried out using a cutter, with the pliers being pressed together after the cutter has been cut into the cable jacket so that the cutting part and the clamping part move away from each other Separate, thereby cutting and separating the cable jacket.

When using the existing wire stripping pliers, the clamping part leaves a notch on the cable sheath, since it always remains in contact with the cable sheath that is not to be separated during the separation of the cable jacket. In the case of a thin cable sheath or a large clamping force, there is a risk of breakage for the remaining cable sheath, which can impair the cable safety and lead to leakage currents. Ever since wire strippers were invented, those skilled in the art have been bothered with the above problems.

Disclosure of the utility model

The object of the present utility model is to provide stripping pliers in which, after a piece of cable jacket has been severed, no notch is left on the remaining cable jacket that could lead to the cable jacket breaking, in order to exclude potential safety risks.

Advantageous effects: Compared to the state of the art, the stripping pliers according to the exemplary embodiments of the present utility model do not leave a notch on the remaining cable sheath that could lead to the breaking of the cable sheath, which contributes to increasing the cable safety. When using the stripping pliers according to the present exemplary embodiment, a cable is inserted into the stripping pliers from the left-hand side and led out of the stripping pliers on the right-hand side. By squeezing the stripping pliers, the clamping part clamps the cable jacket and the cutting edge of the cutting part penetrates the cable jacket. Continued pressing together of the wire strippers causes the clamping part and the cutting part to move away from one another. The cutting edge of the cutting part creates a break point on the cable sheath and the clamping part moves with the clamped cable sheath in a direction pointing away from the cutting part until the cable sheath is separated from the cable. The clamping part holds the separated cable sheath and thus only creates a notch on the separated cable sheath, which has no negative effect on the cable safety. In addition, the cutting edge of the cutting part does not leave any notches on the remaining cable jacket.

Concrete embodiments

In the following, the configurations of the present utility model are described in more detail with reference to the accompanying drawings.

Out 1 shows a wire stripper according to an embodiment of the present utility model, which has a first base body 1 , a second base body 2 , a clamping part 3 and a cutting part 4th comprises, wherein the clamping part 3 with the first body 1 and the cutting part 4th with the second base body 2 is connected, while the first base body 1 and the second base body 2 are rotatably connected to each other. During use, the cable sheath that has been separated is held by the clamping part 3 clamped.

When using the stripping pliers according to the above embodiment, the working surface of the stripping pliers faces the user. As in 2 shown is a cable 5 inserted into the wire stripper from the left side and led out of the wire stripper on the right side. The clamping part is clamped by pressing the wire stripping pliers together 3 the cable jacket and the cutting edge of the cutting part 4th penetrates the cable jacket. By continuing to squeeze the stripping pliers, the first base body 1 and the second base body 2 rotated so that it is on the first base body 1 arranged clamping part 3 and that on the second Base body 2 arranged cutting part 4th move away from each other. How 3 and 4th can be seen, generates the cutting edge of the cutting part 4th a break on the cable jacket and the clamping part 3 moves with the clamped cable jacket into one of the cutting part 4th guiding direction until the cable jacket is separated from the cable. The clamping part holds 3 , as in 5 recognizable, the severed cable jacket 502 and thus only produced on the severed cable jacket 502 a notch. Since the through the clamping part 3 created notch is located on the severed cable jacket, the safety of the cable is not by the clamping part 3 created notch impaired. In the present embodiment, the separated cable sheath 502 on one of the cutting edge of the cutting part 4th facing end cut off, so that the cutting edge of the cutting part 4th no notch on the remaining cable jacket 501 leaves behind.

The embodiment of the present utility model is based on the design idea that when stripping a cable, the cutting edge of the cutting part 4th on the surface of the cable jacket creates a break and the clamping part 3 the severed cable jacket 502 holds clamped to then by means of a movement of the clamping part 3 and the cutting part 4th away from each other to achieve a separation of the cable jacket.

With the embodiment of the present utility model, the problem that has long existed in this field is solved. Ever since wire strippers were invented, when stripping a cable with the aid of wire strippers, the cutting part is used to cut and sever the cable jacket and the clamping part grips the remaining cable jacket 501 so that a notch remains on the cable jacket, which could lead to the cable jacket breaking through and the associated leakage currents and thereby impair the safety of the cable. In the stripping pliers according to the present embodiment, the position of the cutting part and the clamping part is changed, that is, the clamping part engages the separated cable sheath from now on, so that the notch left by the clamping part lies on the separated cable sheath, which has no negative effect on the cable safety Has.

In a preferred embodiment, the clamping part is 3 when the working surface of the wire stripper faces the user, to the right of the cutting part 4th arranged. The working surface of the wire stripper is that surface of the wire stripper on which the clamping part is located 3 and the cutting part 4th are located. When the work surface is facing the user, the clamping part lies 3 to the right of the cutting part 4th . The cable to be processed becomes 5 inserted into the wire stripper from the left side and led out of the wire stripper on the right side. The cutting part is created by squeezing the wire strippers 4th a break and the clamping part on the surface of the cable jacket 3 clamps the cable jacket, causing a movement of the cutting part 4th and the clamping part 3 away from each other. In doing so, the one to the right of the will be cut through 4th The cable sheath generated by the breakage caused by the opposing forces of the cutting part 4th and the clamping part 3 severed. In the meantime the clamping part engages 3 always on the separated cable jacket 502 on.

In a preferred embodiment, the clamping part comprises 3 an upper toothing 301 and one below the upper toothing 301 located lower teeth 302 , with the upper teeth 301 and the lower teeth 302 are arranged opposite one another. With the upper teeth 301 and the lower teeth 302 the cable jacket is clamped.

In a preferred embodiment, the tooth tip of the clamping part 3 , as in 6th shown has an R angle radius of 0.1-5 mm. The R angle radius is the radius of a transition arc at the intersection of two straight lines. Is the R angle radius of the tooth tip of the clamping part 3 less than 0.1 mm, a tooth tip that is too sharp is to be expected, which could easily cut too deeply into the cable sheath and thereby damage the conductor. On the other hand, an R angle radius of the tooth tip of more than 5 mm would in turn lead to a tooth tip that is too blunt, with which the cable sheath cannot be clamped and thus cannot be separated.

In a preferred embodiment, the upper toothing comprises 301 three teeth and the lower toothing 302 four teeth. The clamping part 3 serves to clamp the cable jacket. This includes the upper toothing 301 three teeth and the lower toothing 302 four teeth. With such a toothed structure, different cable sheaths can be severed very well in the respective stripping area.

In a preferred embodiment, the clamping part 3 a tooth pitch of 0.1-3 mm and a tooth depth of 0.1-2 mm. When the tooth tips of the clamping part 3 If the distance from one another is too small of less than 0.1 mm, a slip is often to be expected, ie the clamping part cannot simply cut into the cable sheath and thus cannot successfully separate the cable sheath from the cable. Is the distance between the tooth tips larger than 3 mm, this means tooth tips that are too long and thus too great a total extension of the tooth tips, which makes the arrangement on the pliers head difficult. When the clamping part 3 If the tooth tip has too small a tooth depth of less than 0.1 mm, slip is often to be expected, ie the clamping part cannot simply cut into the cable sheath and thus cannot successfully separate the cable sheath from the cable. If the tooth depth were greater than 2 mm, the clamping part would 3 Slightly cut too deep into the cable sheath and thereby damage the conductor.

In a preferred embodiment, the tooth tip of the cutting part 4th an R-angle radius of 0.01-1 mm. Is the R angle radius of the tooth tip of the cutting part 4th less than 0.01 mm, the tooth tip of the cutting part is too sharp 4th to be expected, which could easily cut too deeply into the cable sheath and thereby damage the conductor. In contrast, an R angle radius would be the tooth tip of the cutting part 4th of greater than 1 mm in turn leads to a tooth tip of the cutting part that is too blunt 4th lead, with which a slip is often to be expected, ie the cutting part cannot cut deeply into the cable sheath and thus cannot successfully sever the cable sheath from the cable.

So far, principles, features and advantages of the present utility model have been presented and described. It will be clear to those skilled in the art that the above specific exemplary embodiments do not constitute a restriction of the present utility model, but merely serve to explain the principles of the present utility model in more detail. Various changes and modifications are possible within the scope of the present utility model, which fall within the scope of protection of the present utility model.
