The utility model provides a circuit breaker welded structure and protection shield make things convenient for the welding of circuit breaker, reduce the welding cost of circuit breaker simultaneously.
Description
Technical Field
The utility model relates to an electronic product protection technical field, specifically speaking relates to a circuit breaker welded structure and protection shield.
Background
At present, if a Breaker (Breaker) is applied to protection in the existing electronic product, one end point of the strip Breaker is welded on a positive electrode lug of a battery cell, and the other end point is welded on a circuit board.
The method must ensure that the size after spot welding is controlled within a range, so a special spot welding jig needs to be designed, and the complexity and the cost of the jig are increased; on the other hand, in order to reasonably use the Breaker, the nickel strips with different shapes and lengths need to be subjected to spot welding on the basis of the Breaker, so that the cost of a spot welding process and the cost of the nickel strips are increased; on the other hand, short circuit between two tabs of the battery cell is easily caused in the Breaker placing and welding process; on the last hand, Breaker in the finished battery needs to be packaged with the battery core into a whole, which causes certain difficulty in subsequent bad analysis.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a circuit breaker welded structure and protection shield make things convenient for the welding of circuit breaker, reduce the welding cost of circuit breaker simultaneously.
The utility model discloses a technical scheme that circuit breaker welded structure and protection shield adopted is:
the circuit breaker welding structure comprises a circuit board, wherein the circuit board is provided with a first bonding pad, the first bonding pad is used for electrically connecting an electric core, the circuit breaker welding structure further comprises a second bonding pad, the second bonding pad is electrically connected with the first bonding pad, and the second bonding pad is used for electrically connecting a circuit breaker.
Preferably, the circuit board is provided with a groove, and the second pad is fixed to a side edge of the groove.
Preferably, the size of the groove is matched with the size of the circuit breaker.
Preferably, the groove penetrates through the top surface and the bottom surface of the circuit board.
Preferably, the groove is formed in the side edge of the circuit board.
Preferably, the second pad is an L-shaped nickel plate.
A protection board comprises a circuit breaker, wherein the circuit breaker is welded on the circuit board.
The utility model discloses a circuit breaker welded structure and protection shield's beneficial effect is: and welding the circuit breaker on the second welding disc, and then welding the battery cell on the first welding disc, wherein the first welding disc is electrically connected with the second welding disc, which is equivalent to welding the circuit breaker on the battery cell. Because the circuit breaker is directly welded on the second bonding pad on the circuit board, a welding jig is saved, the welding times of the circuit breaker are reduced, and the welding cost is reduced. Meanwhile, the circuit breaker and the battery cell are separately welded on the circuit board, so that unsafe factors causing short circuit of the battery cell in the spot welding process are avoided, and the follow-up repair measurement of the circuit breaker is more convenient.
Drawings
Fig. 1 is a schematic structural diagram of the welding structure of the circuit breaker of the present invention.
Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1, the welding structure of the circuit breaker includes a circuit board 10, where the circuit board 10 is provided with a first pad 12, the first pad 12 is used to electrically connect to a battery cell 20, and further includes a second pad 14, the second pad 14 is electrically connected to the first pad 12, and the second pad 14 is used to electrically connect to a circuit breaker 30.
And welding the circuit breaker on the second welding disc, and then welding the battery cell on the first welding disc, wherein the first welding disc is electrically connected with the second welding disc, which is equivalent to welding the circuit breaker on the battery cell. Because the circuit breaker is directly welded on the second bonding pad on the circuit board, a welding jig is omitted, the welding times of the circuit breaker are reduced, the welding cost is reduced, and the service life of the circuit breaker can be prolonged due to fewer welding times. Meanwhile, the circuit breaker and the battery cell are separately welded on the circuit board, so that unsafe factors causing short circuit of the battery cell in the spot welding process are avoided, and the follow-up repair measurement of the circuit breaker is more convenient.
Specifically, there are two first pads 12 corresponding to the positive tab 22 and the negative tab of the battery cell 20, and there are two second pads 14, where one second pad 14 is electrically connected to the first pad 12 corresponding to the positive tab of the battery cell, and the circuit breaker is soldered to the two second pads. The second bonding pad is an L-shaped nickel sheet.
Further, the circuit board is provided with a groove 16, the size of the groove is matched with that of the circuit breaker, and the two second welding discs are fixed on two sides of the groove respectively. Before the circuit breaker is welded, the groove can be used for positioning the circuit breaker, so that subsequent welding is facilitated.
Furthermore, the groove is arranged on the side edge of the circuit board and penetrates through the top surface and the bottom surface of the circuit board. Make things convenient for getting of circuit breaker like this to put, go the back in the circuit breaker welding simultaneously, can not influence the overall dimension of circuit board.
A protection board comprises a circuit breaker, wherein the circuit breaker is welded on the circuit board.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
