Description
Technical Field
The utility model relates to the technical field of circuits, especially, relate to a single section welding point connecting circuit.
Background
Along with the development of electronic technology, the switch control circuit is more and more extensive in the application field of battery, and the kind is more and more, for example triode switch circuit, field effect transistor switch circuit, temperature switch circuit, touch switch circuit etc. control the break-make of electric current in BMS in order to reach the effect of protection circuit device and battery, improve the reliability of BMS function greatly.
In the prior art, the connection electrification of the battery pack and the BMS protection board is mostly carried out in a short nickel sheet welding mode, the electrification mode is not suitable for machine spot welding, and the manual welding also has the risk of causing damage to some components due to the fact that the electrification sequence is wrong.
Therefore, how to better connect the single-joint welding points is a technical problem which needs to be solved urgently by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a single section welding point connecting circuit to solve prior art's problem.
To achieve the above object, a first aspect of the present application provides a single-segment solder joint connection circuit, which includes:
the battery pack comprises a battery power supply input end, a component positive end, a welding point connecting piece, a battery pack and a BMS protection plate;
the battery power supply input end is connected with the battery pack, the positive terminal of the component is connected with the BMS protection board, and the welding point connecting piece is connected with the battery power supply input end and the positive terminal of the component;
the negative electrode of the battery pack is connected with the BMS protection board, and the battery pack and the BMS protection board are grounded.
Specifically, the following technical effects can be achieved:
according to the battery pack protection device, the battery power supply input end is connected with the battery pack, the positive terminal of the component is connected with the BMS protection board, and the welding point connecting piece is connected with the battery power supply input end and the positive terminal of the component; the negative pole and the BMS protection shield of battery package are connected, and the battery package can realize power automatic switch-over output with the BMS protection shield altogether, through the conduction characteristic of nimble short circuit point connection of utilizing, both reduced the risk of damaging components and parts, also reduced the cost.
Drawings
Fig. 1 is a schematic structural diagram of a single-node solder joint connection circuit provided in an embodiment of the present invention.
In the figure, 1 battery power input end, 2 component positive terminals, 3 welding point connecting pieces, 4 battery packs and 5 BMS protection plates.
Detailed Description
The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Examples
The application provides a single section welding point connecting circuit, as shown in fig. 1, this application single section welding point connecting circuit, include:
