Abstract

The utility model discloses a novel wire stripper used for stripping insulation material of an electrical wire head, particularly for separating two wires of a bifilar parallel shield sleeve wire and stripping the insulation material of an electrical wire head in one step. The utility model is characterized in that the wire stripper is provided with an upper base body and a lower base body; a wire casing is respectively arranged at the symmetric positions of the two base bodies; a line dividing blade is arranged closely to the front end of the wire casing of the base body; an elastic force rotating wire stripping blade device is arranged closely to the back end of the wire casing of the base body. When the electric wire is propelled, the electric wire head causes the wire stripping blade rotated backwards to be rushed out; thus, the electric wire head enters the rear face of the wire stripping blade. When the electric wire is pulled out, the elastic force rotating wire stripping blade device causes the blade to clamp the insulation material of the electric wire head; when the electric wire is pulled out, the insulation material can be stripped.

Description

Wire strippers

The utility model wire stripper is used to divest the insulating material of electric wire the end of a thread, as plastics, rubber etc.; Can separate two lines and divest that the end of a thread insulating material is disposable to be finished for bifilar parallel RVV especially.

The main tool that divests the insulating material of electric wire the end of a thread at present is electrician's knife and pincers class etc., with these instruments divest be not easily, very quick, and damage wire core easily, particularly divest bifilar parallel RVV.

The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of operation extremely easy (pull out promptly after the reeve and finish) is provided, extremely fast, does not damage the high-quality wire stripper of wire core.

This novel wire stripper, it is characterized in that: have two matrixes up and down, symmetric position at them respectively has a wire casing, straight-through before and after the wire casing, the lower substrate wire casing is darker, electric wire import department is called front end, and the other end is called the rear end, near the matrix line front of the slot separated time blade is being housed, the edge of a knife is towards front end, bifilar parallel RVV is carried out separated time, inoperative to single strand wire, do not influence its turnover yet, near being housed on the matrix wire casing rear end, two symmetrical elastic force rotating the wire stripping blade device, when electric wire was pushed into, lead made the wire stripping blade backward directions rotate and be washed open, made lead enter wire stripping blade face afterwards; When electric wire was drawn out, this elastic force rotated wire stripping blade device and makes insulating material on the blade chucking lead, was resisted against keeping out on the face of matrix then and stopped operating, being drawn out and insulating material is divested with electric wire.

Performance of the present utility model now by an example, describes with reference to the following drawings.

Fig. 1 is the structure principle chart of this wire stripper.

Fig. 2 is the wire stripping blade schematic diagram.

In Fig. 1～2:

4--spring 5--gear 6--separated time blade

Keep out face 8--lower substrate 9--wire casing before the 7--

10--spring groove 11--rotor unfilled corner fulcrum

Have wire casing ［ 9 ］ on the symmetric position of last lower substrate, near wire casing ［ 9 ］ front position separated time blade ［ 6 ］ is installed, the edge of a knife is towards front end.In this example, the both sides symmetric position is opened an identical groove near wire casing ［ 9 ］ front end, separated time blade ［ 6 ］ promptly is placed in this groove, after last lower substrate associating, make separated time blade ［ 6 ］ location, two symmetrical elastic force rotation wire stripping blade devices are being housed near wire casing ［ 9 ］ back-end location, this device is by wire stripping blade ［ 1 ］, rotor ［ 3 ］, rotor axis ［ 2 ］ and spring ［ 4 ］ are formed, wire stripping blade ［ 1 ］ is fixed on the rotor ［ 3 ］, rotor axis ［ 2 ］ is contained in by the rotor center axis hole in two dead eyes of lower substrate and locatees, spring ［ 4 ］ leans against the interior bottom of groove ［ 10 ］ of lower substrate ［ 8 ］, the other end is butted on the unfilled corner fulcrum ［ 11 ］ of rotor, so when not using, make elastic force rotate the wire stripping blade device abut against lower substrate ［ 8 ］ before keep out on the face ［ 7 ］, two wire stripping blades ［ 1 ］ at this moment just in time relatively in line, when back pulling out electric wire, make the insulating material on wire stripping blade ［ 1 ］ the chucking electric wire, the diameter of the semicircle edge of a knife of the size of wire casing ［ 9 ］ and wire stripping blade ［ 1 ］ can be decided with the wire core thickness, and last lower substrate can be unified into an integral body by screw etc.

Its course of action is as follows:

In bifilar parallel RVV when incoming line is pushed into, separated time blade ［ 6 ］ will be among two lines between the position cutting open, then inoperative to single cord, also do not influence the turnover of electric wire, electric wire continues to be pushed into, when arriving at wire stripping blade ［ 1 ］, because the effect of thrust, rotor ［ 3 ］, wire stripping blade ［ 1 ］ backward directions are rotated, and lead then enters the back of wire stripping blade ［ 1 ］, and at this moment spring is compressed.When back pulling out electric wire, because the effect of spring ［ 4 ］, make the insulating material on wire stripping blade ［ 1 ］ the chucking electric wire, blade also forward direction rotates, this elastic force rotate punck-down block be resisted against lower substrate ［ 8 ］ before keep out on the face ［ 7 ］, so along with being drawn out of electric wire, wire stripping blade ［ 1 ］ is about to insulating material and divests.

Because the size of wire casing ［ 9 ］ and wire stripping blade ［ 1 ］, separated time blade ［ 6 ］ fixed-site,, and avoided the situation of damage wire core so separated time and wire stripping quality are very desirable.

Make when promoting two wire stripping blades ［ 1 ］ at electric wire blade ［ 1 ］ rotate identical angle, can be by the fixing a pair of gear ［ 5 ］ in lower substrate ［ 8 ］ limit outside rotor ［ 3 ］, reason owing to the gears engaged rotation like this, then the angle of two rotor rotation is identical, make two wire stripping blades ［ 1 ］ can be stuck in position mutually neat on the lead, and laborsaving when pulling out electric wire.
