Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of polyethylene insulation instrument signal cable, comprises sheath, the total screen of proof copper-wire braided, proof copper-wire braided sub-shield, insulating barrier, conductor and polyester film belt, and the total screen of described proof copper-wire braided is sleeved on sheath inside; Described proof copper-wire braided sub-shield is distributed in the inside of the total screen of proof copper-wire braided symmetrically; Described insulating barrier is arranged in proof copper-wire braided sub-shield; Described conductor is arranged in insulating barrier; Described polyester film belt is filled in the inside of the total screen of proof copper-wire braided, is provided with buffering and leads core body between described proof copper-wire braided sub-shield; Described buffering is led core body lateral surface and is provided with symmetrically card recess, and the quantity of described card recess is three; Described proof copper-wire braided sub-shield is all connected in card recess, utilizes card recess constraint proof copper-wire braided sub-shield, thereby has effectively avoided proof copper-wire braided sub-shield to twist in the total screen of proof copper-wire braided, can improve the cable molding degree of packing afterwards; The middle part that described buffering is led core body is provided with three dashpots symmetrically, the center that described buffering is led core body is provided with circular cushion hole, described three dashpots all communicate with circular cushion hole, adopt three dashpots all can strengthen the effect of buffering with circular cushion hole.What the inside of traditional insulation instrument signal cable adopted is the structural design contacting between proof copper-wire braided sub-shield, not only toughness is poor, and bending or pull while drawing in daily use procedure, between proof copper-wire braided sub-shield, can rub, and along with the prolongation wearing and tearing of time are more serious, cause the wearing and tearing of proof copper-wire braided sub-shield to be broken, adopt buffering to lead core body, can or pull in bending while drawing, utilize proof copper-wire braided sub-shield extruding buffering to lead core body, thereby realize the effect of buffer protection, thereby adapt to extraneous action, can be to insulating barrier, conductor damages.
The described curved structure of card recess, the arc radius of card recess equates with the exradius of proof copper-wire braided sub-shield, thereby can be by proof copper-wire braided sub-shield being stuck between card recess and the total screen of proof copper-wire braided tightly, and contact fully with proof copper-wire braided sub-shield, bending or pull and be pulled through in journey, utilize proof copper-wire braided sub-shield extruding card recess, and then realize the object of buffering.
Described buffering is led core body and is made up of the elastomeric material of good toughness, thereby in the time of proof copper-wire braided sub-shield extruding card recess, guarantees that card recess can bear the extruding force of proof copper-wire braided sub-shield, can not damage the surface of proof copper-wire braided sub-shield.
The invention has the beneficial effects as follows: the present invention has the advantages such as low cost of manufacture, reasonable in design and long service life; adopt buffering to lead core body; can strengthen toughness can be bending or pull and play buffer protection function while drawing; solve the large drawback of deterioration existing while contacting between the proof copper-wire braided sub-shield of traditional instrument signal cable; effectively prevent that instrument signal cable is actual bending or pull while drawing the phenomenon of fracture occurs, thereby can guarantee that instrument normally works.
