Specific implementation mode
In order to illustrate more clearly of the utility model embodiment and technical solution in the prior art, attached drawing will be compareed below
Illustrate specific embodiment of the present utility model.It should be evident that the accompanying drawings in the following description is only the one of the utility model
A little embodiments for those of ordinary skill in the art without creative efforts, can also be according to these
Attached drawing obtains other attached drawings, and obtains other embodiments.In addition, it is opposite between only indicating each component to be related to belonging to for orientation
Position relationship, rather than absolute positional relation.
It please refers to Fig.1, Fig. 2, Fig. 3.A kind of device for the test of cable conductors adhesive force of the utility model embodiment,
Including：Puller system 1 and the jig 2 for being installed on the puller system 1；The jig 2 includes a fixed cylinder 21, is opened inside fixed cylinder 21
Equipped with one housing the inner cavity 211 of insulating layer 31, and connect with 21 end of fixed cylinder and there is a stop part for detaching hole 223
22, hole 223 is detached with so that conductor 32 is pulled out inner cavity 211 from insulating layer 31, and stop part 22 is to backstop insulating layer 31 by interior
Chamber 211 is pulled out.By stop part 22 to the backstop of cable insulation layer 31, cable conductors 32 can be detached by detaching hole 223
Mode carry out the adhesive force between validity test cable conductors 32 and cable insulation layer 31, to the judgement of cable quality and comment
Valence.
The material of jig 2 is all made of 40Cr, has the characteristics that high rigidity, is unlikely to deform.
Inner cavity 211 can more effectively ensure that cable is straight, it is ensured that cable is not bent, and inner conductor 32 is avoided to detach
When influenced by the cause not of uniform size of 31 frictional force of cable insulation layer, cause surveyed adhesive force bigger than normal than actual numerical value or inclined
Small, data are inaccurate.
Stop part 22 includes stopping seat 221 and backstop 222.Backstop 222 to act as cable in backstop inner cavity 211 exhausted
Edge layer 31 prevents cable insulation layer 31 and follows cable conductors 32 to move together because of the pull of cable conductors 32, while also rising
The effect reinforced is arrived, because during conductor 32 detaches, cable insulation layer 31 can directly act on backstop 222, produce
Raw prodigious pressure can firmly complete cable insulation layer 31 and line by being applied in combination for stopping seat 221 and stop part 22
The separation of cable conductor 32, stopping seat 221 offer to install the location hole of backstop 222, detach hole 223 and be opened in backstop
222, backstop 222 is "convex" shaped, and the part of protrusion can just house in the location hole of stopping seat 221, centainly
The cable insulation layer 31 during cable conductors 32 detach is avoided in degree to be subjected to displacement and shake, and cannot really be reflected
Adhesive force between cable insulation layer 31 and cable conductors 32.
Stopping seat 221 is cylindrical shape, and stopping seat 221 is equipped with the screw thread that can be spirally connected with 21 open end of fixed cylinder.By stopping seat
221 be set as cylindric purpose be can preferably be fixedly connected, stopping seat 221 and fixed cylinder 21 are cylindrical shape, are passed through
Screw thread is spirally connected.Since the mode being spirally connected can not only make connection more firm, while it being also easier to dismounting, installation, not only band
Carry out stability, and embodies good convenience；The connection type of stopping seat 221 and fixed cylinder 21 is not only limited only to
It being spirally connected, can also be connect stopping seat 221 with fixed cylinder 21 by way of clamping, stopping seat 221 is equipped with buckle protrusion, Gu
There is buckle on safety barrel 21, can also reach the effect that is spirally connected by buckling protrusion and being used cooperatively for buckle.
Fixed cylinder 21 is the cavity of one end open, can preferably carry out loading cable to be measured from open section, convenient and efficient,
It also further ensures that cable can keep straight form in the cavity simultaneously, will not be led by environmental factors or cable
The pull of body 32 and deform.
The corresponding other end in 21 open end of fixed cylinder is equipped with interconnecting piece 212.Interconnecting piece 212 is 21 integral type knot of fixed cylinder
Structure act as to be connected to fixed cylinder 21 on 1 pedestal of puller system, and when cable conductors 32 detach, and ensures fixed cylinder 21
Stablize motionless, it is ensured that not the detaching and move with cable conductors 32 of cable insulation layer 31.
Interconnecting piece 212 is equipped with the pin hole 213 passed through for bolt 214, and cylinder is fixed for more convenient in purpose
21 installation, while also ensure that the stability of fixed cylinder 21 well.
Puller system 1 further includes the pulling force fixture 11 that can lock extraction cable conductors 32, pulling force fixture 11 is used for lock wire
Cable conductor 32, and cable conductors 32 are pulled out into cable insulation layer 31.
The cable that one end exposes outside conductor 32, length of cable 400mm are provided, the conductor 32 that stripping insulation layer 31 exposes is grown
Degree is 100mm long, and the section on cable need to handle smooth, avoid influence of the section injustice to adhesive force test result, and will
The cable is placed in the inner cavity 211 of the jig 2, and unstripped 31 end of insulating layer of cable is put into inner cavity 211, cable stripping insulation layer
The conductor 32 that 31 ends are exposed by detaching hole 223 on backstop 222, then by stopping seat 221 and fixed cylinder 21 by screw thread into
Row is spirally connected.
The jig 2 for being built-in with cable is mounted on puller system 1, passes through the interconnecting piece 212 and pulling force in fixed cylinder 21
Machine 1 is attached, specific to be realized by being used cooperatively for bolt 214 and pin hole 213；And cable is made to expose outside conductor 32
End be clamped by machine drawing power 1, after clamping conductor 32 and cable should avoid as possible bending the phenomenon that exist, ensure the true of test result
Reality.
Puller system 1 is finally opened, pulling force fixture 11 drives the conductor 32 of clamping to move upwards, the unstripped insulating layer of cable 31
End is fixed in fixed cylinder 21 so that puller system 1 pulls the conductor 32 of the cable to be detached with insulating layer 31, reads puller system 1
The registration of upper display, obtains test result.
The utility model tests the cable of different model, and fixed cylinder 21 is determined according to the concrete condition of cable
Size and detach hole 223 open up size and location.The jig 2 of plurality of specifications customized can be shifted to an earlier date according to cable model, surveyed
It carries out using with changing according to actual needs when examination.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the scope of protection of the utility model.
