Abstract
The utility model belongs to the technical field of battery connecting tools, and particularly relates to a battery connecting sheet. The battery connecting sheet is characterized by comprising a body in a hollow square shape, wherein a strip-shaped gap is reserved in the upper end of the body; a plurality of welding points are uniformly arranged at both sides of the gap; a plurality of ridges are uniformly arranged on the periphery of the body; one side of the body is fixedly connected with a strip-shaped nickel strap. The battery connecting sheet disclosed by the utility model is simple in structure and convenient to use and enhances the welding strength and prevents the phenomenon of false welding from being generated by releasing a part of welder tension when welded with a battery cover cap and a steel shell bottom. According to the utility model, the area of the nickel strap positioned in a welding point place is enlarged, so that the relative density of the welding points is reduced, and the arc chamfer of a peripheral sheet enhances the safety of the battery after the battery is welded; the integral design of the nickel strap reduces the repeated welding of the nickel strap on the battery and ensures the property of the battery.
Description
(1) technical field
The utility model relates to a kind of cell connector, belongs to battery fastening means technical field.
(2) background technology
Current some batteries are when series and parallel connects combination, need to there is a kind of conductor that these cells are coupled together, current battery combination adopts the welding connecting mode of nickel strap mostly, during use, according to required size, carry out cutting, nickel strap mostly is rectangle, then according to series-parallel mode, nickel strap is stacked up, after stacking up, particularly negative pole causes leakage negative pole burn-through possibly owing to repeatedly repeating welding.The contact area of the local nickel strap of solder joint and battery is little, and solder joint density is large during multiple welding, and the performance of battery is also had a certain impact.Meanwhile, the nickel strap of institute's cutting is integrated type structure, and tension force during welding cannot discharge, and causes rosin joint, thereby affects the performance of battery combination.
(3) summary of the invention
The utility model, in order to make up the defect of prior art, provides a kind of simple in structure, easy to use and can keep the cell connector of battery combination performance.
The utility model is achieved by the following technical solution:
A cell connector, is characterized in that: comprise the body that is " returning " font, body upper end has the gap of strip, and both sides, gap are evenly provided with some solder joints, and body periphery is evenly arranged several tongues, and body one side is fixedly connected with the nickel strap of strip.
Wherein:
Described tongue is equipped with R3 chamfering.
Described body thickness is 0.1-0.5mm, and material is pure nickel, nickel plating or corronil composite band.
The beneficial effects of the utility model are: simple in structure, easy to use; During with battery cap and box hat bottom welding, can release portion welding machine tension force, thus increase weld strength, avoid occurring rosin joint phenomenon; The nickel strap area change in solder joint place, has reduced the relative density of solder joint, and the circular arc chamfering of all sheets has also increased the fail safe after welding battery simultaneously; The integrity design of nickel strap has reduced the repeat welding of nickel strap to battery, has guaranteed the performance of battery.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
In figure: 1, body; 2, gap; 3, solder joint; 4, tongue; 5, nickel strap; 6, chamfering; 7, chamfering.
Embodiment
Accompanying drawing is specific embodiment of the utility model.
The utility model cell connector as shown in Figure 1, comprise the body 1 that is " returning " font, body 1 upper end has the gap 2 of strip, 2 both sides, gap are evenly provided with some solder joints 3, body 1 periphery is evenly arranged several tongues 4, and body 1 one sides are fixedly connected with the nickel strap 5 of strip, and tongue 4 is equipped with R3 chamfering 6, body 1 thickness is 0.1-0.5mm, and material is pure nickel, nickel plating or corronil composite band.
During use, body 1 is placed on the connection in series-parallel cylindrical lithium battery arranging and welds and produce solder joint 3 by electric welding machine, when welding, weld tension force and discharge by the strip gap 2 on body 1, firm welding, battery composite structure is stable.Due to the protrusion nickel strap 5 on body 1, in the increase of when welding bonding area, increased the conductivity of battery.The nickel strap 5 of drawing on body 1 has facilitated the welding of winding displacement in battery pack; The chamfering 6 protection connection lines of the tongue 4 that body 1 periphery is evenly arranged simultaneously, battery combination performance is further enhanced.
Claims (3)
1. a cell connector, it is characterized in that: comprise the body (1) that is " returning " font, body (1) upper end has the gap (2) of strip, both sides, gap (2) are evenly provided with some solder joints (3), body (1) periphery is evenly arranged several tongues (4), and body (1) one side is fixedly connected with the nickel strap (5) of strip.
2. cell connector according to claim 1, is characterized in that described tongue (4) is equipped with R3 chamfering (6).
3. cell connector according to claim 1, is characterized in that described body (1) thickness is 0.1-0.5mm, and material is pure nickel, nickel plating or corronil composite band.
