Abstract

Provided is a telescopic spring type test wire, comprising a housing, a spring, a positioning shaft, a telescopic chuck, a lead and a static chuck. The utility model is characterized in that the lead in the shape of a flat band comprises a metallic inner core and an insulated housing; one end of the lead is connected to the spring which is disposed in the middle of the inner housing, and after the lead coils around the spring for a plurality of circles, the other end of the lead extends outside of the housing through a lead outlet opening and is connected to the telescopic chuck; the static chuck is connected to the spring by lead through another lead outlet opening; the positioning shaft is disposed near the lead outlet opening of the telescopic chuck in the housing so as to reduce the telescopic resistance of the lead. Being capable of conducting stretching and indentation according to different power test situations, the test wire has advantages of meeting the demand of various power test, and greatly saving test cost.

Description

Coil tension spring formula test wire

Affiliated technical field

The utility model relates to a kind of electric wire, especially a kind of coil tension spring formula test wire.

Background technology

In the work about electric power field, often need carry out power test to various electric power facilities, and generally all need the service test lead in the test, because electric power facility is of a great variety, test situation also has nothing in common with each other, so whenever carry out a test, all need to prepare the test lead of one section appropriate length, this waste to lead is very big.

Summary of the invention

At the problems referred to above, the purpose of this utility model is to provide a kind of coil tension spring formula test wire, and this test wire can stretch and indentation at different power test situations, can satisfy the demand of various power tests, saves experimentation cost again greatly.

The technical scheme that its technical matters that solves the utility model adopts is: this coil tension spring formula test wire comprises housing, clockwork spring, locating shaft, flexible chuck, lead, quiet chuck, described lead is the bandlet shape, comprise metal inner core and insulation crust, this lead one end links to each other with the described clockwork spring that is arranged on described enclosure interior central authorities, lead is after multi-turn is walked around in the clockwork spring periphery, the other end stretches out outside the housing by a Tu Xiankou of housing, and links to each other with described flexible chuck, and described quiet chuck is linked to each other with described clockwork spring by behind another Tu Xiankou of described housing by lead, described enclosure interior the telescopic clamp head end tell the line mouth near a described locating shaft is set, to reduce the flexible resistance of described lead.

The beneficial effects of the utility model are: this coil tension spring formula test wire is under non-working condition, clockwork spring is automatically with lead harvest one volume, be convenient for carrying, when needs use, can be according to various test situation, pull out the lead of appropriate length, and with quiet chuck and telescopic clamp head-clamp on testing equipment, can conveniently test, and because the actual access guide passage length in this test wire is constant, so in different tests, the resistance value of this test wire is constant, calculate also very favourable to test for data.

Description of drawings

Accompanying drawing is the structural drawing of this coil tension spring formula test wire.

In the accompanying drawing: 1, housing; 2, clockwork spring; 3, locating shaft; 4, flexible chuck; 5, lead; 6, Tu Xiankou; 7, quiet chuck.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified:

In the accompanying drawing illustrated embodiment, this coil tension spring formula test wire comprises housing 1, clockwork spring 2, locating shaft 3, flexible chuck 4, lead 5, quiet chuck 7, described lead 5 is the bandlet shape, comprise metal inner core and insulation crust, these lead 5 one ends link to each other with the described clockwork spring 2 that is arranged on described housing 1 central interior, and lead 5 is after multi-turn is walked around in clockwork spring 2 peripheries, and the other end by housing 1 tells line mouth 6 and stretches out outside the housing 1, and link to each other with described flexible chuck 4, described quiet chuck 7 is told line mouth 6 backs by lead by another of described housing 1 and is linked to each other with described clockwork spring 2, described housing 1 inside chuck 4 ends that stretch tell line mouth 6 near a described locating shaft 3 is set, to reduce the flexible resistance of described lead 5.

Above-mentioned coil tension spring formula test wire, the metal inner core of described lead 5 is the copper inner core, is of a size of 0.8mm*6.1mm, its unit line length resistance equates with the 2.5mm copper cash.

Above-mentioned coil tension spring formula test wire, described shell 1 is the plastic insulation shell.

Above-mentioned coil tension spring formula test wire, described lead 5 and described clockwork spring 2 riveted joints.

Above-mentioned coil tension spring formula test wire, under non-working condition, clockwork spring 2 is automatically with lead 5 harvests one volume, be convenient for carrying, when needs use, can pull out the lead 5 of appropriate length according to various test situation, and quiet chuck 7 and flexible chuck 4 be sandwiched on the testing equipment, can conveniently test, and because the actual access guide passage length in this test wire is constant, so in different tests, the resistance value of this test wire is constant, calculates also very favourable to test for data.
