Description

Be used for outside short circuit test fixture of battery

Technical Field

The utility model relates to a battery test technical field, more specifically are a be used for outside short circuit test fixture of battery.

Background

A battery refers to a device that converts chemical energy into electrical energy in a portion of the space of a cup, tank, or other container or composite container that holds an electrolyte solution and metal electrodes to produce an electrical current. Has a positive electrode and a negative electrode. The battery is used as an energy source, can obtain current with stable voltage and current, stable power supply for a long time and little influence from the outside, has simple structure, convenient carrying, simple and easy charging and discharging operation, stable and reliable performance and no influence from the outside climate and temperature, and plays a great role in various aspects of modern social life

At present, the existing battery external short circuit testing device has the following problems: the method is characterized in that the short circuit is directly carried out through the clamp attached to the external short circuit box, the method only can carry out short circuit on samples one by one for the battery, generally, the number of samples with the external short circuit is large, the time spent on the samples is long, and when the samples can only carry out short circuit one by one, a large amount of time spent on the short circuit is spent. For this reason, a new scheme needs to be designed to give improvements.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a be used for outside short circuit test fixture of battery has solved the problem that proposes in the background art, satisfies the in-service use demand.

In order to achieve the above object, the utility model provides a following technical scheme: a test fixture for external shorting of a battery, comprising: insulating plank, copper and switch, ten mounting grooves have been seted up on the insulating plank surface, the copper is installed in the mounting groove, fixed screw has been seted up on the copper surface, the switch sets up at the copper top, copper top surface one side is fixed with the wiring board, the vertical terminal that is fixed with in wiring board surface, switch and terminal connection.

As a preferred embodiment of the utility model, fixed screw is provided with nine altogether, just the switch adopts fixed screw of bolt cooperation and copper fixed connection.

As a preferred embodiment of the present invention, the resistance value at both ends of the terminal is 80 ± 20m Ω.

As a preferred embodiment of the utility model, insulated wood's length is 370mm, wide 100mm, high 10mm to 370mm, the width of mounting groove is 30mm, two be provided with the protruding piece between the mounting groove and separate through the protruding piece.

Compared with the prior art, the beneficial effects of the utility model are as follows:

this battery test fixture erects simply, and is easy and simple to handle, and life is relatively poor, can accelerate the short circuit speed, saves engineer's time, makes the test can a plurality of samples carry out the short circuit simultaneously, avoids manual compressing tightly, reduces the survey error to can improve production efficiency, reduce operating personnel's intensity of labour, promote the case progress, bring the benefit for the service customer.

Fig. 1 is a structural diagram of a clamp for testing external short circuit of a battery according to the present invention;

FIG. 2 is a structural diagram of the insulating wood board of the present invention;

fig. 3 is a structural diagram of the copper plate of the present invention.

In the figure, an insulating wood board 1; a mounting groove 2; a copper plate 3; a wiring board 4; a binding post 5; a switch 6; a bump 7; switch fixing screw hole 8.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a test fixture for external shorting of a battery, comprising: insulating wood 1, copper 3 and switch 6, ten mounting grooves 2 have been seted up on insulating wood 1 surface, copper 3 is installed in mounting groove 2, fixed screw 8 has been seted up on 3 surfaces of copper, switch 6 sets up at copper 3 tops, 3 top surface one sides of copper are fixed with

wiring board

4, 4 vertical fixed surface of wiring board have terminal 5, switch 6 is connected with terminal 5, separate into ten mounting grooves 2 with insulating wood 1 top, install copper 3 in every mounting groove 2, switch 6 and terminal 5, the two poles of the earth of power adopt the wire connection on terminal 5, open the short circuit through switch 6, can carry out the short circuit to ten external power sources simultaneously, improve the work efficiency of short circuit.

In a further improvement, as shown in fig. 3: fixed screw 8 is provided with nine altogether, and switch 6 adopts the fixed screw 8 of bolt cooperation and copper 3 fixed connection, uses through fixed screw 8 and bolt cooperation and can fix switch 6, and it is comparatively convenient to install.

Further improved, as shown in fig. 1: the resistance value across the post 5 is 80 ± 20m Ω within the allowable range of the conditions of the regulations.
