Description
Technical field
This utility model is related to a kind of fixture, the rectangular cell fixture of more particularly to a kind of charge-discharge test.
Technical background
Due to electric automobile fast development, electrokinetic cell is extensively applied therewith, and its test process is dashed forward to radiating, safety requirements
Go out.Existing charge-discharge test rectangular cell fixture has compact conformation causes radiating effect difference and both positive and negative polarity wiring same
The problem of side easily short circuit.
Utility model content
Problem to be solved in the utility model is the deficiency existed for existing charge-discharge test rectangular cell fixture, is carried
For a kind of good heat dissipation effect, have short circuit protection, simple structure rectangular cell fixture.
For achieving the above object, this utility model is adopted the following technical scheme that：
A kind of rectangular cell fixture of charge-discharge test, the rectangular cell fixture include train wheel bridge, lower plate and
If the bolt stem being connected between train wheel bridge, lower plate, shown train wheel bridge both sides are provided with for testing the pole piece of wiring, are prevented
The short circuit of battery the two poles of the earth, is evenly arranged with the connecting hole of some connections bolt on the train wheel bridge, lower plate.
Preferably, the groove for determining rectangular cell position, limit are provided with the lower plate along its length between two parties
The slip of battery processed.
Preferably, the groove of the lower plate and train wheel bridge middle position are correspondingly arranged on connecting hole, the company
Connect and be connected between hole for isolating the bolt of adjacent cell, for ensureing that adjacent cell is not contacted.
Preferably, described connecting hole includes some counterbores being uniformly arranged on the train wheel bridge and corresponding
The through hole being arranged on the lower plate.
Preferably, the pole piece is connected with train wheel bridge by cementing, process is simple low cost.
This utility model is had the advantage that with effect：Due to the jig Design using many cells in column, each list
The area of dissipation of body is big, good heat dissipation effect；The pole piece of test wiring is distributed in train wheel bridge both sides, and battery can be avoided to test
Wiring short circuit in journey；Bolt hole between adjacent cell position can ensure that adjacent cell is not contacted, simple effective.

Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the utility model is elaborated.
A kind of deficiency of this utility model for the rectangular cell fixture presence of existing charge-discharge test, there is provided charge and discharge
The rectangular cell fixture of electrical testing.
Shown in Fig. 1, a kind of rectangular cell fixture of charge-discharge test, the rectangular cell fixture include train wheel bridge 1, under
Clamping plate 2 and 5 bolts 4 being connected between train wheel bridge 1, lower plate 2,1 both sides of shown train wheel bridge are provided with and connect for test
4 pole pieces 3 of line, prevent the short circuit of battery the two poles of the earth, the 5 connections bolt 4 are evenly arranged with the train wheel bridge 1, lower plate 2
Connecting hole.
Described connecting hole include some counterbores 5 being uniformly arranged on the train wheel bridge 1 and it is corresponding be arranged on it is described
Through hole 6 on lower plate 2.
The number of pole piece 3 is but is not limited to 4, as long as disclosure satisfy that the cell quantity of test, that is to say, that
During the cell that test is more than 2, need to increase pole piece number.The distribution of pole piece is to prevent the positive and negative extremely short of rectangular cell
Connect and be evenly distributed on train wheel bridge both sides.
Shown in Fig. 2, the number of the counterbore 5 of train wheel bridge 1 is but is not limited to 5, and the length and width of train wheel bridge 1 are both needed to according to being tested
Rectangular cell size design, the selection of material species is but is not limited to bakelite；Train wheel bridge 1 with 3 connected mode of pole piece be but
It is not limited to be glued, it is contemplated that process costs problem, connected mode are preferably glued.
Shown in Fig. 3, the number of the through hole 6 of lower plate 2 is but is not limited to 5, and the selection of material species is but is not limited to phenolic aldehyde modeling
Material.Lower plate 2 is provided with groove 7 along its length between two parties, and its width and depth are determined all in accordance with rectangular cell to be tested, limit
The slip of battery processed.
According to the height of the rectangular cell tested, the selected length for obtaining bolt 4 determines that the effect of bolt 4 is in charge and discharge
Enough pretightning forces are provided for battery during electrical testing, it is to avoid battery and 3 loose contact of pole piece.
Shown in Fig. 4, the bottom of the first square battery 8 and the second square battery 9 is embedded in the groove 7 of lower plate 1, square
The both positive and negative polarity of battery top is contacted with the pole piece 3 on train wheel bridge 1, produces enough pretightning forces by each bolt 4, makes two squares
The both positive and negative polarity of battery respectively with 3 reliable contacts of pole piece, they are limited by a bolt 4 between two pieces of batteries and are contacted with each other.
Preferred embodiment of the present utility model is these are only, is not used to limit this utility model.For the skill of this area
For art personnel, this utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle within, made
Any modification, equivalent substitution and improvements etc., should be included within protection domain of the present utility model.
