It is arranged in proof copper-wire braided sub-shield；Described conductor is arranged in insulating barrier；Described mylar belt is filled out
Fill the inside at the total screen layer of proof copper-wire braided；It is provided with between described proof copper-wire braided sub-shield and toughness reinforcing leads core body.
The inside of traditional insulation instrument signal cable uses the structure contacted between proof copper-wire braided sub-shield
Design, not only toughness is poor, and when bend during daily use or pull draw time, proof copper-wire braided divides
Can rub between screen layer, and prolongation abrasion over time is more seriously, causes proof copper-wire braided to divide
Screen layer abrasion ruptures, and uses toughness reinforcing core body of leading, it is possible to strengthens the toughness of cable, solves traditional
The drawback that when contacting between proof copper-wire braided sub-shield, the deterioration of existence is big, effectively prevents instrument from believing
Number cable bends or pulls the phenomenon that fracture occurs when drawing during actual use, thus the cable extended
Service life.
Described toughness reinforcing core body lateral surface of leading is provided with card recess symmetrically, the described curved structure of card recess,
The arc radius of card recess is equal with the exradius of proof copper-wire braided sub-shield, and the quantity of card recess is at least
Two；Described proof copper-wire braided sub-shield is all connected in card recess；The described toughness reinforcing inner side leading core body
Middle part is provided with ductile buffer groove symmetrically.Utilize card recess to fetter proof copper-wire braided sub-shield, thus avoid
Proof copper-wire braided sub-shield twists in the total screen layer of proof copper-wire braided, can improve the consolidation after cable molding
Degree；When during actually used, appearance bends or pulls and draws, it is possible to increased by the extruding of proof copper-wire braided sub-shield
Tough core body of leading, and then inward compression ductile buffer groove, improve the toughness of cable, be effectively prevented electricity
The skin breakage of cable or internal break, it is ensured that the normal use of instrument.
The quantity of described ductile buffer groove is equal with the quantity of card recess, the curved structure of ductile buffer groove,
Using arcuate structure can match with card recess, when there is extruding, ductile buffer groove is compressed, thus
Play the effect of buffer protection, enhance the toughness of cable to a certain extent.
The invention has the beneficial effects as follows: the present invention has reasonable in design, low cost of manufacture, service life
The advantages such as length and good toughness, use toughness reinforcing core body of leading, it is possible to strengthen the toughness of cable, solve traditional
The drawback that when contacting between proof copper-wire braided sub-shield, the deterioration of existence is big, effectively prevents instrument from believing
Number cable bends or pulls the phenomenon that fracture occurs when drawing during actual use, thus the cable extended
Service life, can ensure that instrument normally works.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the internal structure schematic diagram of the present invention；
Fig. 2 is the toughness reinforcing structural representation leading core body of the present invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect,
Below the present invention is expanded on further.
As shown in Figure 1 to Figure 2, a kind of insulation instrument signal cable, including sheath 1, the total screen layer of proof copper-wire braided
2, proof copper-wire braided sub-shield 6, insulating barrier 4, conductor 3 and mylar belt 5, described proof copper-wire braided always shields
Cover layer 2 and be sleeved on sheath 1 inside；Described proof copper-wire braided sub-shield 6 is uniformly and symmetrically distributed always shields at proof copper-wire braided
Cover the inside of layer 2；Described insulating barrier 4 is arranged in proof copper-wire braided sub-shield 6；Described conductor 3 is arranged on absolutely
In edge layer 4；Described mylar belt 5 is filled in the inside of the total screen layer of proof copper-wire braided 2；Described proof copper-wire braided
It is provided with between sub-shield 6 and toughness reinforcing leads core body 7.The inside of traditional insulation instrument signal cable uses copper
The structure design contacted between silk woven separated-shielding layer 6, not only toughness is poor, and when in daily use
During bend or pull when drawing, can rub between proof copper-wire braided sub-shield 6, and prolongation over time
Abrasion is more serious, causes proof copper-wire braided sub-shield 6 abrasion to rupture, and uses toughness reinforcing core body 7 of leading, energy
Enough strengthen the toughness of cable, solve the mill existed when contacting between traditional proof copper-wire braided sub-shield 6
The big drawback of loss, effectively prevents instrument signal cable from bending or pulling when drawing during actual use
The phenomenon of generation fracture, thus the service life of the cable extended.
