Description

a wire stripper

technical field

The utility model relates to a wire stripper.

Background technique

In the prior art, a wire stripper includes a clamping part and a cutting part. When stripping the wire sheath with a wire stripper, the clamping part clamps the wire sheath, and the cutting part cuts the wire sheath and removes the stripped part. There will be clip marks of the clip on the wire sheath that has not been peeled off. During this action, the clamping part plays a role of fixing and clamping, and the shearing part cuts the wire sheath and removes the peeled wire sheath. For example, in the wire strippers disclosed in Chinese Patent No. ZL200820134236.4, Chinese Patent No. ZL 200820137083.9, and Chinese Patent No. ZL201220255751.4, the clamping part is arranged on the left side, and the cutting part is arranged on the right side. In normal use, hold the tool with the right hand, put the wire into the holding part with the left hand, thread the wire from left to right, adjust the stripping position, and then hold the tool with the right hand to peel off the wire skin.

In addition, setting the guide structure on the right side of the wire stripper also proves that the threading enters the wire stripper from the left. The guide ruler is used to guide the measurement distance. For example, in Chinese Patent No. ZL 99208670.1, Chinese Patent No. ZL 200820137082.4, Chinese Patent No. ZL 201520842060.8, Chinese Patent No. ZL 201720198261.8, and U.S. Patent No. US D771,458S, the guide rulers are located on the right side of the wire stripper. .

At present, all the wire strippers in the world use this structure. The design idea of the prior art is: to strip the wire sheath with a wire stripper, it is necessary to use a knife edge to cut, and after the knife edge sinks into the wire sheath, hold the pliers body to separate the cutting part and the clamping part. This realizes cutting and pulling off the thread skin.

In the existing wire stripping pliers, since the clamping part is always clamped with the unstripped wire sheath during the process of removing the wire sheath, the clamping part leaves an indentation on the wire sheath. If the sheath is thin or the clamping force is high, there is a risk that the sheath that has not been stripped will be pinched. This is not conducive to the safety of the cable, and there is a potential leakage hazard. After the utility model of the self-stripping pliers, the above-mentioned technical problems have always troubled those skilled in the art.

As shown in FIGS. 3 and 4 , the cutting edge of the shearing part 4 cuts a break on the wire sheath, and the clamping part 3 clamps the wire sheath and moves away from the shearing part 4 until the wire sheath is peeled off from the cable. At this time, as shown in FIG. 5 , the clamping part 3 clamps the stripped wire sheath 502 , and the indentation of the clamping part 3 on the cable is only located on the stripped wire sheath 502 . Since the indentation of the clamping part 3 is located on the peeled wire sheath, the indentation of the clamping part 3 will not affect the safety of the cable. In the present embodiment, the cut end of the stripped wire sheath 502 is at the wire sheath where the cutting edge of the shearing part 4 is located. In this way, the cutting edge of the cutting part 4 will not leave any cut on the remaining wire sheath 501 .

The design idea of the embodiment of the present invention is that, when peeling off the wire sheath, a cut is made on the surface of the wire sheath by the knife edge of the shearing part 4, the clamping part 3 clamps the stripped wire sheath 502, and the clamping part 3 and the shear The opposite movement of the cut parts 4 causes the thread sheath to be peeled off.

The embodiments of the present invention solve long-standing technical problems in the technical field. After the wire stripper is used in the utility model, when stripping the wire sheath, the shearing part cuts and strips the wire sheath, and the clamping part is clamped on the remaining sheath 501 . The clamping part leaves indentations on the cable sheath, which will damage the cable sheath, cause leakage, and affect the safety of the cable. In the wire stripper of this embodiment, the positions of the cutting part and the clamping part are changed, the clamping part is clamped on the stripped wire sheath, and the indentation left by the clamping part is located on the stripped wire sheath, which does not affect the stripped wire sheath. Cable safety.

As a preferred example, when the working surface of the wire stripper faces the user, the clamping part 3 is located on the right side of the cutting part 4 . The working surface of the wire stripper refers to the side on which the clamping part 3 and the cutting part 4 are arranged on the wire stripper. When the working surface faces the user, the gripping part 3 is located on the right side of the cutting part 4 . The cable 5 to be processed is inserted from the left side of the wire stripper and passed out from the right side of the wire stripper. Hold the wire stripper tightly, the cutting part 4 cuts the incision on the surface of the wire sheath, the clamping part 3 clamps the wire sheath, and the cutting part 4 and the clamping part 3 move opposite to each other. The wire sheath located on the right side of the cut incision of the shearing part 4 is peeled off under the action of the opposite force of the shearing part 4 and the clamping part 3 . The gripping portion 3 is always gripped with the peeled wire sheath 502 .

As a preferred example, the clamping part 3 includes an upper tooth part 301 and a lower tooth part 302 located below the upper tooth part 301 , and the upper tooth part 301 and the lower tooth part 302 are arranged opposite to each other. The upper tooth part 301 and the lower tooth part 302 are used to realize the clamping of the wire sheath.

As a preferred example, the R angle radius of the tooth tip portion in the clamping portion 3 is 0.01 to 5 mm. The R corner radius is the radius of the transition arc where the two straight lines meet. If the R angle radius of the tooth tip portion of the clamping portion 3 is less than 0.01 mm, the tooth tip portion is too sharp, and it is easy to cut too deep into the wire sheath and damage the wire. If the R angle radius of the tooth tip is greater than 5mm, then the tooth tip is too blunt to clamp the wire sheath, and it is easy to slip, making it impossible to strip the wire.

As a preferred example, the upper teeth portion 301 includes three teeth, and the lower teeth portion 302 includes four teeth. The clamping part 3 clamps the wire sheath. The upper tooth portion 301 includes three teeth, and the lower tooth portion 302 includes four teeth. The tooth structure can very well peel off various wire sheaths within the scope of wire stripping.

As a preferred example, in the clamping portion 3, the tooth pitch is 0.1 to 3 mm, and the tooth depth is 0.2 to 1.5 mm. If the distance between the tooth tips of the clamping part 3 is less than 0.1 mm, then the distance between the tooth tips is too narrow, it is not easy to cut into the wire sheath, it is easy to slip, and the wire cannot be stripped. If the distance between the tips of the teeth is greater than 3mm, the tips of the teeth are too long, resulting in an excessively long total distance between the tips of the teeth, which is inconvenient to be arranged on the cutter head. If the tooth depth is less than 0.2 mm, the tooth tip of the clamping part 3 is too shallow, it is not easy to cut into the wire sheath, it is easy to slip, and the wire cannot be stripped. If the tooth depth is greater than 1.5 mm, the clamping part 3 is likely to cut too deep into the wire sheath and damage the wire.

As a preferred example, the R angle radius of the tooth tip portion in the shearing portion 4 is 0.01 to 2 mm. If the R angle radius of the tooth tip portion of the shearing portion 4 is less than 0.01 mm, the tooth tip portion of the shearing portion 4 is too sharp, and it is easy to cut too deep into the wire skin and damage the wire. If the R angle radius of the tooth tip of the shearing part 4 is greater than 2 mm, the tooth tip of the shearing part 4 is too blunt and cannot penetrate deeply into the wire sheath, and it is easy to slip, so that the wire cannot be stripped.

The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited by the above-mentioned specific embodiments. The above specific embodiments and descriptions in the specification are only intended to further illustrate the principles of the present invention.
