Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, the present invention provides an embodiment of a connecting strip for forming an angle terminal lead-acid battery, which includes a connecting strip composed of two connecting blocks 1 and a middle connecting rod 3.

Two

connecting blocks

1 and 3 appearances of intermediate junction pole are a rectangular shape structure, and two connecting blocks 1 are equipped with respectively and match connecting hole 2 that corresponds with positive, negative angle type terminal 4 structure, and two connecting blocks 1 are connected through intermediate junction pole 3, and two connecting blocks 1 are central symmetry shape, and two connecting hole 2 widths of connecting block 1 are than the intermediate junction pole width.

The two connecting blocks 1 and the middle connecting rod 3 are made of lead-antimony alloy, and after the lead-antimony alloy is molten, the lead-antimony alloy is molded through gravity casting of a mold with a corresponding structure. The outer demoulding inclination of the two connecting blocks 1 and the middle connecting rod 3 is 5 degrees, the inner hole demoulding inclination of the connecting hole 2 is 3 degrees, and the connecting strips can be conveniently and smoothly demoulded after casting and forming.

About the less 3mm of 4 total heights of angle type terminals of 1 thickness of two connecting blocks, because 2 hole drawing of patterns inclinations of connecting hole are 3, connecting block 1 is connected the back with

angle type terminal

4, 1 bottoms of connecting block can not with 4 bottom parallel and level of angle type terminal, make 1 bottoms of connecting block have no support, closely cooperate with angle type terminal 4 through self gravity, connect more firmly.

Connecting holes 2 of the two connecting blocks 1 penetrate through the connecting blocks 1, and the length and width of the inner parts of the connecting holes 2 are matched with the structural size of the angle-shaped terminal 4.

When the lead-acid storage battery terminal is welded, the angle-shaped terminal 4, a battery pole and a lead ring are welded to form a positive terminal and a negative terminal, so that the top of the lead ring is a lead plane, and an original angle-shaped terminal structure is arranged beside the lead ring. In order to avoid connecting block 1 and angle type terminal 4 to be connected the back, the terminal top plane of angle type terminal 4 interferes with the connecting hole 2 bottom and leads to being connected not hard uply, do to excavate the processing in connecting hole 2 bottom, form the groove of dodging of excavating, the width of dodging the groove is unanimous with the plumbous planar width in top of angle type terminal 4, and the degree of depth is 6mm to this realizes that connecting hole 2 and angle type terminal 4 closely cooperate.

The length of the middle connecting rod 3 corresponds to the distance between the batteries when the batteries are formed, and the distance between the batteries after the 2 batteries are connected in series through the connecting strips is ensured to meet the requirements of manufacturers.

Because the internal structure of the connecting hole 2 corresponds to the structure of the angle-shaped terminal 4, when the battery is connected, the connecting holes 2 of the two connecting blocks 1 are only needed to be respectively buckled on the positive and negative terminals of the 2 batteries, and the connecting holes 2 can be tightly matched with the terminals, so that the purposes of convenient production and operation and high efficiency are achieved.

The connecting strip is lead-antimony alloy, and the reaction between the lead-antimony alloy and acid mist formed in the formation process is slow, so that the connecting strip can be used for a long time.

The invention principle and design idea of the connecting strip comprise the following contents:

A. the whole connecting strip is of a long strip-shaped structure, and the two connecting blocks 1 are provided with the connecting holes 2 matched with the size of the battery terminal, so that the connecting strip is connected with the battery terminal.

B. These two connecting blocks 1 are connected through middle connecting rod 3, and two connecting blocks 1 are central symmetry shape, and connecting hole 1 width is wider than middle connecting rod 3.

C. In order to enable the connecting strip to be resistant to corrosion and used for a long time in an acid mist environment, the connecting strip is made of lead-antimony alloy, and when the connecting strip cannot be used, the connecting strip can be melted again and then cast into the connecting strip, so that cyclic utilization is realized.

D. The connecting strip is formed by gravity casting, and the external demoulding inclination of the connecting strip is set to be 5 degrees and the internal hole demoulding inclination is set to be 3 degrees so as to facilitate demoulding after casting and forming.

E. About 1 thickness of connecting block is about 3mm less than angle type terminal overall height, because 2 hole drawing of patterns inclinations of connecting hole are 3, connecting block 1 is connected back connecting strip bottom with the terminal and can not with angle type terminal bottom parallel and level, makes the connecting strip bottom not have the support, closely cooperates with the terminal through self gravity, connects more firmly.

F. Connecting holes 2 at two ends of the connecting block 1 penetrate through the connecting strip, and the length and the width of each connecting hole 2 are consistent with those of the angle-shaped terminal, so that the connecting holes 2 and the terminals can be tightly matched.

G. In order to solve the problem that the connection between the connecting hole and the terminal is loosened due to the interference between the bottom of the connecting hole 2 and the plane of the terminal, the bottom of the connecting hole 2 is hollowed, the hollowed width is consistent with the width of the plane of the terminal, and the hollowed depth is 6mm.
