The terminal tension tester
Technical field
The utility model relates to a kind of test fixture, is specially a kind of terminal tension tester.
Background technology
Terminal and electric wire ways of connecting generally are welding or compress electric wire through pressure with terminal; When electric wire with after terminal is connected; Usually all need test whether firmly or whether rosin joint of connection; But this test does not have special-purpose instrument, generally all is to test through the mode that stretches by hand, does not connect reliably as long as do not come off after stretching promptly to be judged as.Therefore but such stretching is a loaded down with trivial details job for operating personnel, and the defensive position that repeatedly stretches can pain, and influence is worked normally, designs a kind of frock that can calibrating terminal degree of being connected firmly and is very important.
The utility model content
To the problem that exists in the prior art, the purpose of the utility model is to provide a kind of technical scheme of terminal tension tester.
Described terminal tension tester; Comprise base, be arranged on locating support and fixed support, pull bar, counterweight and test block on the base; Said pull bar is arranged on locating support and the fixed support, and pull bar one end can rotate around fixed support, and the pull bar other end is movably arranged on the locating support; Said test block is set in place in the pull bar of fixed support one side terminal, and said counterweight is set in place in the pull bar of locating support one side terminal.
Described terminal tension tester, said locating support is provided with the stopper slot of positioning tie bar.
Described terminal tension tester, said pull bar is rotatably assorted through straight pin and fixed support.
Described terminal tension tester, said locating support all links to each other with base through hexagon socket head cap screw with fixed support.
The utility model is simple in structure, is skillfully constructed, when needs calibrating terminal pulling force; Only need terminal be hung on the test block; Firmly toward drop-down, if counterweight can be pulled up and terminal does not come off with lead, i.e. judgement meets the requirements then; And can change counterweight according to the requirement of varying strength, laborsaving saving time.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1-base, 2-fixed support, 3-locating support, 4-counterweight, 5-pull bar, 6-straight pin, 7-test block.
Embodiment
Below in conjunction with Figure of description the utility model is further specified:
The terminal tension tester; Comprise base 1, be arranged on locating support 3 and fixed support 2, pull bar 5, counterweight 4 and test block 7 on the base 1, wherein, pull bar 5 is arranged on locating support 3 and the fixed support 2; Pull bar 5 one ends can rotate around fixed support 2; Pull bar 5 other ends are movably arranged on the locating support 3, and test block 7 is set in place in the pull bar of fixed support 2 one sides terminal, and counterweight 4 is set in place in the pull bar of locating support 3 one sides terminal.When test, terminal is hung on the test block to drop-down, pull bar can rotate around fixed support, and the pull bar that is positioned at the locating support side can perk, and after resetting, pull bar then falls in the stopper slot on the locating support.
In the utility model; Locating support all links to each other with base through hexagon socket head cap screw with fixed support, and pull bar is rotatably assorted through straight pin and fixed support, and aforesaid way is not limited in the connection between these parts; As long as can realize its effect, other connected modes all can.
The utility model is simple in structure, is skillfully constructed, when needs calibrating terminal pulling force; Only need terminal be hung on the test block; Firmly toward drop-down, if counterweight can be pulled up and terminal does not come off with lead, i.e. judgement meets the requirements then; And can change counterweight according to the requirement of varying strength, laborsaving saving time.
