Description
Technical field
This utility model belongs to cable low-temperature impact test device field, more particularly, to a kind of cable low-temperature impact test device.
Background technology
Along with the development of ICT, the consumption that makes of cable (cable, optical cable) also rapidly increases.In order to control the quality of cable products, domestic and international specifications of cables all defines multinomial method of testing, and low-temperature impact test is also wherein important one.
TIA/EIA-455-25CS-2002 is the standard for cable impact test method that ANSI issues.In many international standards, cable low-temperature impact test all quotes the method described by this standard.With reference to Fig. 1, jump bit 101 is walked around a pulley 103 mainly through a stay cord 102 and is connected with pivoted arm 104.Jump bit 101 is guided by a guide hole and remains vertically oriented motion.Pivoted arm 104 can freely-movable, and driven rotation by drive rod, when pivoted arm 104 direction overlaps with stay cord, weight now position is the highest, when pivoted arm 104 somewhat continues this uneven point of deviation, due to pivoted arm 104 can freely-movable, jump bit 101 freely falling body falls down, impact lower section chopping block 105 on sample 106.Therefore, drive rod rotates one week, and sample 106 is carried out one-shot by jump bit 101, and jump bit 101 impact distance is determined by pivoted arm 104 length, and test low temperature environment is by whole case control.This apparatus structure is complicated, it is desirable to be able to the motor of stable operation under low temperature state, and general low-temperature test is required at low temperatures (such as-30 DEG C) maintenance more than 4 hours, and the lubrication of motor and whole actuating device is proposed significantly high requirement.It addition, when jump bit 101 freely falling body impacts, its momentum also can be produced certain impact by the freely-movable of stay cord 102 and pivoted arm 104, thus reducing the accuracy of test.
GB GB/T2951.14-2008 also specify the low-temperature impact test method of cable, with reference to Fig. 2, its test parameters is different from above-mentioned Unite States Standard, impacts mode also less consistent, but ultimate principle is still under cryogenic, use jump bit 201 freely falling body that cable surface is impacted.Whole assay device need to be put in high-low temperature test chamber and test.Its jump bit 201 is intermediate throughholes column pouring weight, one cross section of middle fixed placement is the guide rod of triangle, and medium height position is provided with horizontal platform, can move up and down adjustment shock height, equipped with a J type fixture on platform, it is used for fixing and discharges jump bit 201.The principle of the low-temperature impact test device of current domestic a lot of manufacturer production be substantially Fig. 2, or only facilitate the folding of control J-shaped chuck outside high-low temperature chamber plus circuit or machine control unit.This apparatus structure is relatively easy, but its J type switch needs operator's Non-follow control, and this is accomplished by operator and enters high/low temperature circulating box.This may require that whole sweat box has enough volumes and operator wears antifreezing protection clothes and tests on the one hand, opens thermocycling chamber door on the other hand, whole test environment temperature can be produced certain fluctuation thus affecting result of the test under low-temperature condition.Moreover, this design can only impact sample once every time, if needing repeat impact, then needs operator manually to be mentioned by jump bit 201 and puts back to original position.At present a lot of manufacturers control the folding of J-shaped chuck plus circuit or machine control unit outside high-low temperature chamber, but multiple shock test still needs operator to open chamber door that jump bit 201 is resetted.
