As shown in fig. 1, the present embodiment provides a bus bar testing tool, which includes a mounting base 10, two mounting members 20, and a pressure detection module. Two installed parts 20 are arranged on the installation seat 10 at intervals, the two installed parts 20 are used for respectively fixing two ends of the bus bar 100, the bus bar 100 is fixed in position through fixing the two ends of the bus bar 100, and dislocation of the bus bar 100 during testing is avoided. The bus bar 100 is provided with a mounting hole, and a fastener, which is a bolt in this embodiment, passes through the mounting hole and then is fixed to the mounting member 20. The pressure detection module is disposed between the mounting member 20 and the mounting base 10, and is used for sensing and displaying a force applied to the mounting member 20 when the bus bar 100 is fixed to the mounting member 20.

In this embodiment, when the bus bar 100 is fixed to the mounting member 20 by the bolts, the force applied to the bus bar 100 by the bolts is transmitted to the pressure detection module through the mounting member 20, and the force applied to the mounting member 20 is detected by the pressure detection module, so that the pressure applied to the bus bar 100 when the bus bar 100 is fixed by the bolts can be reflected to a certain extent, and the bus bar 100 is prevented from being deformed due to an excessively large force. Through the detection of pressure measurement module and demonstration power, can provide the additional action for when installing busbar 100, be favorable to in time knowing busbar 100's fixed firm degree.

In particular, the pressure detection module comprises a pressure sensor and a display 31. The pressure sensor is clamped between the mounting seat 10 and the mounting part 20, so that the force applied to the bus bar 100 can be transmitted to the pressure sensor through the mounting part 20 according to a certain proportion; the display 31 is electrically connected to the pressure sensor for displaying the value detected by the pressure sensor. In this embodiment, the force applied to the bus bar 100 when the bus bar is engaged with the bolt is reflected by the engagement of the pressure sensor and the display 31, so as to provide auxiliary guidance for fixing the bus bar 100 and prevent the bus bar 100 from bending due to an excessive force applied thereto, thereby ensuring the accuracy of the test result.

Alternatively, a plurality of pressure sensors may be provided, and the display 31 displays an average value of the plurality of pressure sensors to more accurately reflect the stress condition of the bus bar 100.

Optionally, the pressure detection module can also include a warning light, and the warning light can report to the police when the pressure sensor testing result surpasses or is close to the threshold value to make things convenient for operating personnel in time to adjust the elasticity degree of bolt.

To facilitate the fixing of the busbar 100, the mounting member 20 is provided with a threaded hole which is threadedly engaged with the bolt. Because the diameters of the bolts matched with the bus bars 100 of different types are different, in order to enable the test tool to be compatible with the bus bars 100 of different types, threaded holes with various apertures are formed in the mounting piece 20, and the threaded holes are used for being matched with the bolts to fix the bus bars 100 on the mounting piece 20.

Since the lengths of the different busbars 100 may vary, the positions of the threaded holes in the two mounting members 20 may vary when the different busbars 100 are secured in order to allow the busbars 100 to naturally flatten during testing.

In order to accommodate busbars 100 of different lengths, the mounting members 20 are provided with elongated slots 21, the elongated slots 21 extend in the arrangement direction of the two mounting members 20, and threaded holes are provided in the bottom surfaces of the elongated slots 21. When the bus bar 100 is fixed, the position of the bolt in the long groove 21 is adjusted according to the length of the bus bar 100, so that the test requirement is met.

In some embodiments, the inner wall of the elongated slot 21 may be threaded to mate with a bolt, thereby eliminating the need for a threaded hole.

In some embodiments, the elongated slot 21 may not be provided, and correspondingly, a plurality of threaded holes with the same diameter are provided and arranged along the arrangement direction of the two mounting members 20. When fixing the busbar 100, the threaded hole matching the aperture on each mount 20 can be selected according to the length of the busbar 100 to meet the test requirements.

Further, the mount 20 is provided in plural and detachably connected to the mount 10. All be provided with the screw hole on every installed part 20, can select suitable installed part 20 as required during test busbar 100 to satisfy the test demand better.

To better accommodate busbars 100 of different lengths, the mounting seat 10 comprises two seats 11 and an adjustment seat. Each support 11 is provided with a mounting part 20; the adjusting seat is arranged between the two supports 11 and is detachably connected with the two supports 11 respectively, and the adjusting seat comprises a plurality of seat bodies 12 which can be spliced, and the number of the spliced seat bodies 12 is adjustable so as to adjust the length of the adjusting seat. The length of the adjusting seat can be changed by selecting the number of the seat bodies 12 and splicing the seat bodies to form the adjusting seat, so that the distance between the two supports 11 can be adjusted, and the bus bars 100 with different lengths can be adapted.

When the bus bar test tool is used, firstly, the length of the adjusting seat is adjusted by adjusting the number of the seat bodies 12, so that the distance between the two support seats 11 is roughly adjusted. Then, the fixing position of the bus bar 100 is finely adjusted by adjusting the position of the bolt in the long groove 21, so that the bus bar 100 is naturally flattened.

In order to facilitate the splicing of the seat bodies 12, one end of each seat body 12 is provided with a fixture block 121, the other end of each seat body 12 is provided with a clamping groove, and the fixture block 121 on any one seat body 12 can be clamped into the clamping groove on the other seat body 12. When two adjacent seat bodies 12 are connected, the clamping block 121 is clamped into the clamping groove, so that the assembly is convenient.

Optionally, the clamping groove may be a through groove, so that the clamping block 121 can be clamped into the clamping groove from a penetrating direction of the through groove, and the operation is more convenient.

Optionally, the support 11 and the adjacent seat 12 can be detachably connected through the cooperation of the clamping groove and the clamping block 121, and can also be connected through a fastener such as a screw.

Optionally, the plurality of bodies 12 have at least two lengths. Through being equipped with the pedestal 12 of different length, can adjust the length of adjusting the seat on the basis that does not change the 12 quantity of use pedestals for adjust seat length adjustment more nimble, convenient.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention.
