Abstract
The invention discloses a lead release force testing mould and method. The lead release force testing mould comprises a stainless steel three-dimensional plate which is 90mm long, 80mm wide and 5mm high, wherein the plate is provided with a through hole in the middle along the longitudinal direction, the diameter of the through hole is more than that of a conductor by 0.15mm, and the through hole is provided with a circular nest-shaped groove with depth of 2mm in one surface of the plate. During testing, an insulation part is stripped from one end of a sample to ensure that the length of a residual insulation part is (50+1) mm so that the exposed conductor end penetrates through one surface with the circular nest-shaped groove, then a conductor is fixed at the upper end of a tensile machine clamp, the stainless steel plate is fixed at the lower end of the tensile machine clamp, a tensile machine speed is set according to a specified stripping speed, and a tensile machine is switched on to start the stripping; when an insulation layer of a lead at the lower end of the stainless steel plate is separated from the plate, insulation stripping is completed, and a maximal force displayed on the tensile machine is a stripping force. The lead release force testing mould has the advantages of simple structure, easy availability of materials, and convenience in processing; the testing method has the advantages of simple step and convenience in operation.
Description
Technical field
The present invention relates to wire and detect, specifically a kind of wire stripping power testing mould and method of testing.
Background technology
Large commercial aircraft wire, because environment for use is harsh, higher to safety requirements, so manufacturer's standard is strict.Conventionally according to standard A S22759, carry out the test of large commercial aircraft wire in the world, wherein need be to the wire peel test force that insulate by standard.
Although standard A S22759 has stipulated the parameter that requires of insulation peeling force, the description without specific experiment with mould and equipment, in industry also without special-purpose assorted testing mould and equipment and relevant test method, the accurate test lead peeling force that insulate.
Summary of the invention
The object of this invention is to provide a kind of testing apparatus of simple in structure, easy processing and more easy method of testing accordingly.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: a kind of peel test force mould, and it includes sheet material, it is characterized in that: described sheet material is stainless steel cube, the middle part of described sheet material has through hole, and described through-hole surfaces is provided with round shape nest groove.
Described board dimension is long 90mm, wide 80mm, high 5mm;
Described through-hole diameter is conductor diameter+0.15mm.
Described round shape nest groove depth 2mm.
A method of testing for peeling force, is characterized in that:
Comprise the steps:
(1) by sheet material with the facing down of circle shape nest groove, be fixed on puller system lower end;
(2) sample conductor one end is divested to insulation course, makes long (50+1) mm of residue insulation, by exposed conductor end from there being the one side of round shape nest groove to penetrate the through hole of sheet material, pass sheet material after conductor be fixed on clamp of tensile machine upper end;
(3) with the peeling rate stipulated, set puller system speed, start puller system, peel off beginning, when sheet material conducting wire at lower end insulation course departs from sheet material, complete insulating stripping from, the maximum, force showing on puller system had been both peeling force.
This invention beneficial effect is as follows: mould structure is simple, and material is common, easy to process; Through hole one side, with circle shape nest groove, can make insulation course extruding stressed evenly when peeling off, and improves the accuracy of test; Method of testing step is simple and easy, convenient operation.
