High-current clamp device

Abstract

The invention relates to a high-current clamp device. The high-current clamp device comprises an injection molded part, at least one current sheet and at least one voltage sheet; the mounting surfaceof the injection molded part is divided into a current sheet mounting area and a voltage sheet mounting area which are located side by side; a side surface of the injection molded part is provided with binding posts; the outer ends of the binding posts are electrically connected with external devices; the inner ends of the binding posts extend to the current sheet mounting area and the voltage sheet mounting area respectively and are in contact connection with corresponding current sheets and corresponding voltage sheets; after being stacked and laminated, the current sheets are horizontally fixed to the current sheet mounting area of the injection molded part through corresponding bolts; and after being stacked and laminated, the voltage sheets are horizontally fixed to the voltage sheetmounting area of the injection molded part through corresponding bolts. According to the high-current clamp device of the invention, the over-current capacity of the clamp device can be increased or decreased by increasing or decreasing the current sheets; and reliable connection between battery lugs and charging and discharging power sources can be realized under a condition that the surfaces ofbattery pole sheets are not damaged with clamping facilitated.

Description

technical field [0001] The invention relates to a large current clamp device. Background technique [0002] The high-current fixture is an important basic component in the formation and capacity separation equipment of polymer power batteries, but the existing fixtures have disadvantages such as inconvenient change of type and cost-effective damage to the surface of the battery tab. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a high-current fixture device suitable for charging and discharging various types of soft-packed polymer power batteries, which is convenient for replacement operation, high in crimping reliability, and low in contact resistance. [0004] The high-current fixture device of the present invention is characterized in that it includes an injection molded part, at least one current plate and at least one voltage plate, and the installation surface of the injection molded part is divided into a sid...
