In many electronic products (for example mobile phone), need to be equipped with battery, battery is connected through electrode terminal with needs between the product body, flows to the product body with the electric weight with battery.Form stable electrical the contact between electrode terminal and the battery in order to make, the electrode terminal that is adopted in the product body usually is the elastic electrode terminal, through the elastic force of elastic electrode terminal self, makes itself and the electrode of battery form stable electrical the contact.See shown in Figure 1; This is present common a kind of elastic electrode terminal; It comprises: egative film 21; Extending shape along egative film 21 left and right sides has stator 22,23, and turnup extends to form a crooked arm of force 24 backward along egative film 21 front sides, and the end of the arm of force 24 is the contact point 25 with battery (or other electrical products).Wherein the contact point 25 of the arm of force is positioned at the top of egative film 21.

There is following defective in the electrode terminal of this structure:

1, terminal structure is complicated, not only processing trouble, and inconvenient during assembling.

2, the terminal arm of force of this flexible terminal is shorter, and through after the life test to product, serious sinking can appear in the contact point 25 of terminal; Its life-span is reduced widely, and this situation why occurring is because the arm of force of this terminal is shorter; And main elastic deformation concentrates on the bend of the arm of force 24 and egative film 21, and after the electrode of products such as contact point 25 and battery contacted, contact point 25 moved downwards under pressure; The elastic deformation internal stress of the arm of force 24 will mainly concentrate on above-mentioned bend this moment; Long slightly when service time, irreversible deformation will take place in this bend, causes the product distortion; The arm of force 24 can't restore to the original state, and sinking just appears in contact point 25.

3, behind this flexible terminal finished product, need use special CAP as auxiliary suction means in process of production, this just influences production cost of products and production efficiency.

The utility model content:

The utility model technical problem to be solved is to overcome the deficiency of prior art, provides a kind of simple in structure, and the elastic electrode terminal of long service life.

In order to solve the problems of the technologies described above; The utility model has adopted following technical proposals: this elastic electrode terminal comprises the integrated base and the terminal arm of force; Described base is a plane lamellar body, along extending to form the described terminal arm of force on the side screw of base.

Furthermore, in the technique scheme, the terminal position of the described terminal arm of force is formed with lug boss.

Furthermore, in the technique scheme, the described terminal arm of force is the moulding that narrows down gradually by base to its end.

Furthermore, in the technique scheme, described terminal arm of force surface is to the center inclined position.

Furthermore; In the technique scheme; The described terminal arm of force comprises: by first kink of base one lateral buckling extension, by second kink of first kink bending extension and the 3rd kink that is extended by the bending of second kink, wherein said boss is in the binding site place of second kink and the 3rd kink.

Furthermore, in the technique scheme, the described terminal arm of force can adopt slick and sly crooked curved surface.

Furthermore, in the technique scheme, described base comprises main body and extension, and this extension is the plane that is formed by main body one side spiral extension, and the described terminal arm of force is by extending to form on the terminal screw of extension.

Furthermore, in the technique scheme, described main body has an automatic adsorption plane of drawing.

The utility model compared with prior art, it has following beneficial effect:

1, the utility model terminal arm of force adopts rotary structure, and it can effectively increase the length of the terminal arm of force, when terminal is worked; The internal stress that the terminal arm of force produces because of compressive deformation will be distributed in the whole long arm of force; And the deformation position that stress is concentrated can not appear in the utility model, and the stress on the whole like this terminal arm of force on the single point will reduce, and can make product smoothly through life test; Unusual situation can not occur testing, increase the useful life of terminal greatly.

2, after the utility model is made moulding, after plating, can directly roll over the strip packing, need not anchor clamps, reduce production cost.

3, the base of the terminal of the utility model is the class wafer body on a plane, helps inhaling the part operation in the automated production automatically, can enhance productivity.

4, the utility model simple in structure, be convenient to machine-shaping.
