Yet because the electronic industry competition is day by day fierce, conventional battery lug and battery protecting apparatus solder technology are time-consuming, taking a lot of work causes manufacturing cost to increase, and has not met demand now, and necessity of improvement is arranged in fact.
Therefore, how to solve above-mentioned the problems of the prior art and defective, be the inventor and desire most ardently the direction place that research improves with the relevant manufacturer that is engaged in the industry.
Summary of the invention
The inventor is because above-mentioned defective, so collect related data, via assessing in many ways and consider, and to engage in the industry accumulation many years of experience, via constantly studying and revising, designs patent of the present invention at last.
Main purpose of the present invention is to provide a kind of more cheap battery pole ear of man-hour and cost and welding method of battery protecting apparatus of saving.
In order to achieve the above object, the welding method of battery pole ear of the present invention and battery protecting apparatus comprises:
An one protective device link and a battery pole ear are provided;
Place a conductor and be connected in the one side of this protective device link and this battery pole ear; And
The one side of this protective device link and this battery pole ear is carried out a spot welding processing procedure, make this protective device link be connected in this battery pole ear.
In a preferred embodiment, the one side of this protective device link and this battery pole ear is carried out a spot welding processing procedure, further comprise: the one side that this protective device link and this battery pole ear is placed with this conductor is carried out a spot welding processing procedure.
In a preferred embodiment, this protective device link is copper or nickel.
In a preferred embodiment, this battery pole ear is an aluminium.
In a preferred embodiment, this conductor is copper or copper alloy.
Welding method according to aforementioned battery pole ear and battery protecting apparatus; The present invention utilizes conductor to substitute nickel strap as the bridge between protective device link and the battery pole ear; The two procedures that makes script need simultaneously is reduced to only wants one procedure promptly to accomplish the be connected operation of protective device link with battery pole ear; Therefore, the present invention can effectively save processing procedure, man-hour, further reaches the effect that reduces cost.

The specific embodiment
For reaching above-mentioned purpose and effect, technological means that the present invention adopts and structure, conjunction with figs. just preferred embodiment of the present invention explains that in detail its characteristic and function are following, understands fully being easy to:
See also Fig. 3, Fig. 4 and shown in Figure 5, be respectively flow chart, the enforcement sketch map of preferred embodiment of the present invention, find out that by knowing among the figure welding method of battery pole ear of the present invention and battery protecting apparatus comprises:
101 provide a protective device link and a battery pole ear;
102 place the one side that a conductor is connected in this protective device link and this battery pole ear; And
The one side of 103 pairs of these protective device links and this battery pole ear is carried out a spot welding processing procedure, makes this protective device link be connected in this battery pole ear.
In this step 101; Like Fig. 4; In present embodiment; This protective device link 21 is connected to the battery protecting apparatus (not shown), and this battery protecting apparatus possibly be breaker (Breaker) or self-resetting type electric current fuse (PTC), and this battery pole ear 22 is connected to the lithium polymer battery (not shown).Preferably, this protective device link 21 is copper or nickel, and this battery pole ear 22 is an aluminium.
In this step 102, in present embodiment, this conductor 23 is positioned over the bottom surface of this protective device link 21 and this battery pole ear 22, and preferably, this conductor 23 is copper or copper alloy.
