Specific embodiment
The technical solution of the utility model is described further below in conjunction with attached drawing.
As shown in Figures 1 to 5, the grafting closing device for battery testing of the utility model includes cylinder 1, movable plate
2, plug assembly 3, guide pin 4, positioning plate 5, cylinder 1 are fixed on positioning plate 5, and movable plate 2 is fixedly connected on the piston of cylinder 1
On bar.Movable plate 2 is square shape cavity structure in the utility model, and plug assembly 3 is fixed on square shape cavity structure lower part, this
Sample is convenient for fixing the installation of 3 conducting wire of plug assembly.In the utility model, 2 lower part of movable plate be arranged guide pin 4, guide pin 4 with
The location hole of battery modules is correspondingly arranged, it is ensured that 31 insertion position of probe is accurate.
As shown in figure 3, the plug assembly 3 of the utility model includes 33,4, line 4 probes 31, plugboard 32 and measurement spies
Needle 31 and measurement line 33 are mounted on plugboard 32, and every group of battery modules test includes 4 probes 31 in this way.In test, often
One electrode of group battery modules can using two detections measurement, so as to prejudge every group of battery modules battery electrode column and
Voltage between busbar connector, and then the case where can quickly judge whether there is rosin joint.
As shown in Figure 4 and Figure 5, the probe 31 of the utility model includes 311, conductive column 312, probe set 313, spring of probe
314, snap ring 315, conductive column 312 are movably connected in probe set 313 by spring 314, and snap ring is arranged in 313 top of probe set
315, snap ring 315 prevents conductive column 312 from skidding off out of probe set 313, and 312 upper and lower ends of conductive column stretch out probe set 313, conductive
312 lower part of column setting probe 311, probe 311 is connect preferably by the mode of threaded connection with conductive column 312, because using
