Abstract

The utility model relates to an antistatic protection control cable for the electronic production equipment, comprising a cable core, an outer insulation layer of the cable core, a wire braid and an outer protection layer. The cable core is is composed of a plurality of strands of FEP poly perfluoroethylene signal conductors and a plurality of cotton fiber threads which make the cable core become tensile. The outer insulation layer of the cable core is the PTFE thin film insulation layer which winds the cable core. The wire braid is an electromagnetic shielding lay of the cable and adopts stainless steel wires to knit and winds tightly the outer insulation layer of the cable core. The outer protective coating is an antistatic and corrosion resistant insulation layer with a smooth appearance, and the material is the antistatic silicone rubber. The outer protective coating is coated by the wire braid. The control cable of the utility model not only has favorable heat resistance and corrosion resistance, but also has favorable electromagnetic interference resistance performance and the antistatic. In addition, the dust cannot stick to the surface of the antistatic protection control cable for electronic production equipment, and the antistatic protection control cable for electronic production equipment is widely used in electron manufacturing equipment which has high requirements on the antistatic performance.

Description

A kind of electronic production equipment is with antistatic defense controls cable

Technical field:

The utility model relates to a kind of electronic production equipment with antistatic defense controls cable, especially can be used as the equipment cable that electronic devices and components manufacturing site location antistatic dust protection is had relatively high expectations, as welding or sealing-off equipment.

Background technology:

At present, requiring the electronic devices and components manufacturing site location of antistatic dust protection, all devices, equipment is for preventing electrostatic effect, all solve by the mode that makes its metal shell good earth, but Equipment Control cable, then there are not electromagnetic shielding and anti-static precautions, the exterior protection layer is the ordinary rubber layer, when this electric control cable places outside the equipment or is connected between the equipment, particularly direct at the equipment that is connected, frequent contact electronic devices and components occasion, as welding or sealing-off equipment, cable is easily because cable inside energising work or external electrical field effect or be stained with adhesive tape static dust and make the appearance static electrification, jeopardize electronic devices and components in one's power, simultaneously, cable heat-resisting, corrosion resistant performance is also poor.

Summary of the invention:

Problem according to above-mentioned existence, the purpose of this utility model is to provide a kind of novel electron production equipment control cable, except that possessing existing performance of general control cable and attribute, other makes this kind cable possess electromagnetic shielding, antistatic, the function that is not covered with dust and outer corrosion resistant performance.

For achieving the above object, the utility model control cable comprises: cable core, cable core external insulation layer, wire braid and external protection coating;

Described cable core is by multiply FEP polyfluorinated ethylene signal conductor and many cotton fiber lines of cable core tension are formed, described cable core external insulation layer is the PTFE thin dielectric film, twine described cable core,, described wire sheathing is closely compiled around described cable core external insulation layer by special process; Described external protection coating adopts antistatic corrosion resistance insulating material to make, and the described wire sheathing that closely is covered especially makes its outer surface be made into smooth shape, just makes the utility model;

As a kind of improvement of the present utility model, described control cable is closely compiled around its cable core external insulation layer by wire sheathing, can make cable possess electromagnetic shielding action, makes described control cable not cause its appearance static electrification because of inside energising work;

As another kind of improvement the of the present utility model, described control cable external protection coating adopts the insulating material of antistatic corrosion resistance, and its appearance is made into smooth shape, can make its surface not because of the external electrical field effect or be stained with the dust static electrification of adhesive tape static;

The antistatic performance of the utility model control cable can make it when on the sealing-off equipment that is used in the precise electronic chip especially, and the probability that chip is smashed owing to electrostatic interaction greatly reduces, less than ten thousand/.

FEP polyfluorinated ethylene signal conductor 1, cable core external insulation layer 2, metal wire knitted 3, external protection coating 4; Cotton fiber line 5;

Embodiment:

In order to further specify above-mentioned purpose of the present utility model, structure and effect, embodiment of the present utility model is described below in conjunction with accompanying drawing;

Fig. 1 is the structural diagrams of the utility model control electric wire, and Fig. 2 is the cross section diagram of the utility model control cable line;

Comprise: FEP polyfluorinated ethylene signal conductor 1, cable core external insulation layer 2, dense metal wire knitted 3, external protection coating 4, cotton fiber line 5;

The cable core of forming described cable by many cotton fiber lines 5 of multiply FEP polyfluorinated ethylene signal conductor 1 and tension; Closely twine with the PTFE insulation film in described cable core outside, the winding layer that constitutes is described cable core external insulation layer 2, described cable core external insulation layer 2 outside closely volumes around the stainless steel wire wire sheathing, both be described dense wire sheathing 3, dense wire sheathing 3 makes cable possess the effect of electromagnetic shielding; Adopt the described stainless steel wire wire sheathing of the tight lining of silicon rubber of corrosion resistance, antistatic, just constitute external protection coating 4,, guarantee that the appearance of described external protection coating 4 is smooth shape, just made originally the utility model control cable by special process;

The utility model control cable, under above-mentioned structure, feature and material use, especially volume around stainless copper wire wire braid form antistatic silicon rubber overcoat antistatic that electro-magnetic screen layer, appearance be smooth shape, be difficult under the protection condition of sticking dust, just the utility model control cable possesses good antistatic performance.

The utility model control cable can be widely used in the electronic devices and components manufacturing site location, in the demanding equipment of antistatic.
