In the utility model, cooperated using the through-hole on the limit hole and limit plate on supporting plate, so that one end of battery core can
It is fixed in limiting slot with passing through through slot, and the tab of the battery core can be passed through by limiting the through-hole of trench bottom, so that
The battery core enters suspended state, and the battery core of suspended state is not only convenient for connecting test fixture and has good heat dissipation effect,
And it can effectively improve the reliability of test data, while avoiding causing battery core short circuit wind because explosion-proof tank inner wall insulation layer is worn
Danger.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of test fixture suitable for large capacity cylindrical electrical core structural schematic diagram.
Specific embodiment
In the following, the technical solution of the utility model is described in detail by specific embodiment.
As shown in FIG. 1, FIG. 1 is the utility model proposes a kind of test fixture suitable for large capacity cylindrical electrical core knot
Structure schematic diagram.
Referring to Fig.1, the utility model proposes a kind of test fixture suitable for large capacity cylindrical electrical core, comprising: supporting plate
1, limit plate 2 and pedestal 3, in which:
Supporting plate 1 is located at the top of pedestal 3 and fixed by support frame 4 and pedestal 3, and the lower surface of supporting plate 1 is upper with pedestal 3
It is reserved with spacing between surface, supporting plate 1 is equipped with the limiting slot being recessed from its upper surface to its lower surface direction, and limiting slot
Bottom is equipped with the through-hole passed through for tab.Limit plate 2 is located at the top of supporting plate 1 and connect with support frame 4, the following table of limit plate 2
Spacing is reserved between face and the upper surface of supporting plate 1, limit plate 2 is equipped with through slot up and down, and through slot is on supporting plate 1
Orthographic projection is Chong Die with limiting slot.
What the utility model used: so that one end of battery core is passed through through slot and protrude into limiting slot, to utilize limiting slot and through slot
Cooperation makes the battery core keep vertical suspended state, and the tab of the battery core can extend into support across the through-hole of limit trench bottom
Then the tooling is put into explosion-proof tank by the lower section of plate 1, so that the battery core will not be contacted with the inner wall of explosion-proof tank, finally
The tab of the battery core is clamped using the test fixture in test equipment to carry out test jobs.
From the foregoing, it will be observed that the utility model is cooperated using the through-hole on the limit hole and limit plate 2 on supporting plate 1, so that battery core
One end can pass through through slot be fixed in limiting slot, and the tab of the battery core can by limit trench bottom through-hole pass through,
So that the battery core enters suspended state, and the battery core of suspended state is not only convenient for connecting test fixture and has good dissipate
Thermal effect, and can effectively improve the reliability of test data, while avoiding causing electricity because explosion-proof tank inner wall insulation layer is worn
