Abstract

The present invention discloses an insulating sleeve structure for new energy vehicle battery assembling. The structure comprises: a first adapter, wherein the upper portion of the first adapter is circular and is provided with a square standard slot, and the lower portion of the first adapter is provided with a cross-shaped plug; a middle insulation connection body, wherein the outer surface of the middle insulation connection body is provided with a first cylindrical structure, the middle portion of the first cylindrical structure comprises a cross-shaped plug, and the external portion of the first cylindrical structure is provided with four grooves with inclination angles of 45 degrees; and a second adapter, wherein the outer surface of the upper half portion of the second adapter is provided with a second cylindrical structure, the external portion of the second cylindrical structure comprises four stand columns with inclination angels of 45 degrees, and the lower half portion of the second adapter is a standard square head. The insulating sleeve structure is simple and reasonable, and convenient to install and use. the middle insulation connection body only bears the pressureload and does not load the torsion load so as to ensure that the insulation sleeve can bear large torque load, the insulating sleeve structure is high in withstand voltage, long in service life, goodin insulation effect and safe and reliable.

Description

technical field [0001] The invention relates to the technical field of tightening tools, in particular to an insulating sleeve structure for new energy vehicle battery assembly. Background technique [0002] During the assembly process of new energy battery packs, many assembled DC battery packs are connected by bolts. During live assembly, according to the existing tightening process, the sleeve used between the tightening tool and the tightening drive device (manipulator tightening gun) passes through The internal metal parts are connected, and when the positive and negative poles of different polarity groups of battery branches or battery assemblies are tightened, a current circuit between electrodes is formed and short-circuited, making the battery pack scrapped or damaged. [0003] In order to solve the above problems, the insulating sleeve commonly used in the market is to wrap a layer of heat-shrinkable insulating material on the outer wall of the tightening tool or t...
