Abstract
The utility model provides an elastic lead, which comprises an insulating casing and a copper wire. The copper wire is arranged in the insulating casing in a sine curve form, and the insulating casing is an elastic rubber casing. The elastic lead can not only conduct circuits safely and effectively, but extend and retract optionally on the premise of not changing self resistance, thereby meeting requirements of different electrical engineering and electric power tests.
Description
Technical field
The utility model relates to a kind of electric wire, especially a kind of elastic wire that can arbitrarily stretch and shorten.
Background technology
Present lead is made up of insulation crust and copper cash, and the length of copper cash and insulation crust is all fixed, and it is non-stretchable, and in some electricians, power test process, usually to use the lead of certain-length, after test is finished, because the length of test lead is often in an awkward position., can't be used for other electric power facilities safely, so just directly abandoned under a lot of situation, this has just caused the waste of lead.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of elastic wire, this elastic wire is turning circuit safely and effectively not only, and can be arbitrarily flexible under the situation that does not change self-resistance, to satisfy the demand of various different electricians, power test.
The technical scheme that its technical problem that solves the utility model adopts is: this elastic wire comprises insulation shell and copper cash, and copper cash is the sine curve shape and is arranged in the insulation shell, and described insulation shell is the elastic caoutchouc shell.
As preferably, described insulation shell cross section is circular, and its diameter is not less than 5mm.
As preferably, the coefficient of elasticity of described insulation shell is less than 10N/m.
The beneficial effects of the utility model are: this elastic wire can be according to various electrician, the power test demand optionally stretches, and conduction test circuit, and under the little situation of stretch range, copper cash in the lead is owing to be the setting of sine curve shape, the electromagnetic radiation so two adjacent copper cash can also be cancelled out each other, this helps improving the accuracy of cranking test, this elastic wire is turning circuit safely and effectively not only, and can be arbitrarily flexible under the situation that does not change self-resistance, to satisfy various different electricians, the demand of power test has reduced the waste of lead.
Description of drawings
Fig. 1 is the vertical section figure of this elastic wire.
Among the figure: 1, insulation shell; 2, copper cash.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
As shown in Figure 1, this elastic wire comprises insulation shell 1 and copper cash 2, and described copper cash 2 is the sine curve shape and is arranged in the insulation shell 1, and described insulation shell 1 is the elastic caoutchouc shell.
Above-mentioned elastic wire, described insulation shell 1 cross section are circular, and its diameter is not less than 5mm.
Above-mentioned elastic wire, the coefficient of elasticity of described insulation shell 1 is less than 10N/m.
Above-mentioned elastic wire can optionally stretch according to various electrician, power test demand, and conduction test circuit, and under the little situation of stretch range, copper cash 2 in the lead is owing to be the setting of sine curve shape, the electromagnetic radiation so two adjacent copper cash can also be cancelled out each other, this helps improving the accuracy of cranking test, this elastic wire is turning circuit safely and effectively not only, and can be arbitrarily flexible under the situation that does not change self-resistance, to satisfy the demand of various different electricians, power test, reduced the waste of lead.
Claims (3)
