Abstract

The utility model provides a prevent electrically welding spark sensor cable, includes insulation core, isolation layer, oversheath, the outer cladding of isolation layer have the oversheath, be equipped with the cable core that forms by 2~20 insulation core transposition in the isolation layer, insulation core form by inner conductor and the insulating layer of cladding outside the inner conductor, the oversheath outward still the cladding have the close aramid fiber silk of knitting. The utility model discloses an advantage and beneficial effect: the cable can use under high temperature for a long time, prevention splash electric spark that can be fine has good compliance to the injury of cable simultaneously, be convenient for the cable frequent crooked, remove the operation, this cable design is reasonable, has good compliance, bendability, environmental protection, prevents the electric spark characteristic, the feature of environmental protection of cable can not cause the corruption to precision equipment, has guaranteed the personal safety, can not cause the pollution to the atmospheric environment simultaneously, can satisfy installation, the operation requirement of the processing of machine -building trade and robot.

Description

A kind of anti-electric welding spark sensor cable

Technical field

The utility model belongs to sensor cable field, particularly a kind of softness, environmental protection, anti-electric welding spark sensor cable using in machine industry and processing of robots field.

Background technology

Along with social development, especially reaching its maturity of sensor industry development, also progressively increases progressively for the cable demand of sensor field. In the field of machine industry and processing of robots, especially having under electric welding spark use occasion, even if adopt cross-linking radiation protective cover material cable surface also can sustain damage unavoidably, cannot meet the requirements such as high temperature resistant, anti-electric welding spark, environmental protection and softness.

Summary of the invention

Problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of can meet machine industry and the instructions for use of processing of robots field are provided, there is the sensor cable of good flexibility, high temperature resistant, anti-electric welding spark, long service life.

The utility model solves its technical problem and takes following technical scheme to realize:

A kind of anti-electric welding spark sensor cable, comprise insulated wire cores, separation layer, oversheath, it is characterized in that: described separation layer is coated with oversheath, in separation layer, be provided with by 2 ~ 20 stranded cable cores that form of insulated wire cores, described insulated wire cores is made up of inner wire and the insulating barrier being coated on outside inner wire, and described oversheath is also coated with the close aramid fiber yarn of knitting outward.

Further, the incorgruous strand of bare copper wire interlayer that it is 0.1mm by multiply diameter that described inner wire adopts is made to stranded, and this structure makes this sensor cable have good flexibility and bendability.

Further, described oversheath adopts irradiation cross-linking flame-retardant polyurethane material, make the Limit of Long-Term operating temperature of conventional polyurethanes cable be increased to 100 DEG C by 80 DEG C, and there is more excellent resistance to bend(ing) and wearability compared with traditional cable, simultaneously greatly improve cable the heat endurance of 200 DEG C, strengthened the ability of the resistance to electric welding spark of cable.

Further, the outer painting of described insulated wire cores is shaped with separation layer, and this separation layer can be avoided adhesion between solid wire, when cable moving, between each insulated single wire, can relatively produce slip, has played the effect that strengthens cable flexibility, and cable is improved compared with common cable flexibility.

The utility model compared with prior art has significant advantage and beneficial effect: aramid fiber yarn can use continuously under 205 DEG C of conditions, not melting under hot conditions, and this Materials Fracture intensity is high, well chemical resistance, cable can at high temperature use for a long time. Aramid fiber is high flexibility macromolecule in addition, and the well injury of pre-antispray electric spark to cable of close volume one deck aramid fiber yarn has good flexibility simultaneously, is convenient to frequent bending, the move operation of cable; This cable design is reasonable, has good flexibility, bendability, environmental protection, anti-electric spark character; The feature of environmental protection of cable can not cause corrosion to precision equipment, has ensured personal safety, can not pollute atmospheric environment simultaneously, can meet installation, the instructions for use of machine industry and processing of robots.

Fig. 1 is structural representation of the present utility model;

Wherein 1, inner wire, 2, insulating barrier, 3, separation layer, 4, oversheath, 5, aramid fiber yarn.

Detailed description of the invention

Below in conjunction with accompanying drawing and preferred embodiment, to the detailed description of the invention providing according to the utility model, structure, feature and effect thereof, be described in detail as follows.

The anti-electric welding spark sensor of one cable as shown in Figure 1, comprise insulated wire cores, separation layer 3, oversheath 4, described separation layer 3 is coated with oversheath 4, in separation layer, be provided with by 2 ~ 20 insulated wire cores with the stranded cable core forming of the certain ratio pitch of stranded cable external diameter rule, described insulated wire cores is made up of inner wire 1 and the insulating barrier 2 being coated on outside inner wire, and described oversheath is also coated with the close aramid fiber yarn 5 of knitting outward.

Described inner wire 1 adopts the incorgruous stranded ultra-fine bare copper wire of multilayer to make, and this structure makes this sensor cable have good flexibility and bendability.

Described oversheath 4 adopts irradiation cross-linking flame-retardant polyurethane material, make the Limit of Long-Term operating temperature of conventional polyurethanes cable be increased to 100 DEG C by 80 DEG C, and there is more excellent resistance to bend(ing) and wearability compared with traditional cable, simultaneously greatly improve cable the heat endurance of 200 DEG C, strengthened the ability of the resistance to electric welding spark of cable.

The outer painting of described insulated wire cores is shaped with separation layer, and this separation layer can be avoided adhesion between solid wire, when cable moving, between each insulated single wire, can relatively produce slip, played the effect that strengthens cable flexibility, and cable is improved compared with common cable flexibility.

Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model. All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
