Process and result.
Therefore, it is necessary to a kind of high resistive fuse detection device of precision is provided to solve the above problems.
【Utility model content】
The main purpose of the utility model is that providing a kind of precision high resistive fuse detection device, can ensure
The continuity of detection process and the precision of testing result.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of high resistive fuse detection dress of precision
It puts, including actuator, by the voussoir that actuator driving moves up and down, with the voussoir realization is coordinated to open with closing
A pair of of conducting clamp assemblies of conjunction, the conducting clamp assemblies include the fixed pin for being symmetricly set on both sides below the voussoir
Axis, the connecting rod being arranged on the fixed pin shaft, the insulated heat block for being fixed on the connecting rod lower end, be fixed on it is described insulation every
Two pieces of steel discs of heat block lower surface, two connecting rods are linked together in upper end by elastic component, two pieces of steel disc difference
It is contacted with two stems in fuse, the width of the steel disc is at least five times of stem width, under the voussoir is
The structure for holding the small upper end width of width big.
Further, the fixed pin shaft is arranged on fixed block, and the fixed pin shaft is connected with the middle part of the connecting rod.
Further, the upper end of the connecting rod is provided with shaft, is provided in the shaft and is contacted with the wedge surface

【Specific embodiment】
Embodiment：
Fig. 1-Fig. 2 is refer to, the present embodiment is the high resistive fuse detection device 100 of precision, including actuator
1st, driven moving part 1 drives the voussoir 2 to move up and down, a pair of of the conducting clamping group opened with being closed is realized with the cooperation of voussoir 2
Part, the conducting clamp assemblies include being symmetricly set on the fixed pin shaft 3 of 2 lower section both sides of voussoir, be arranged on fixed pin shaft 3
