Movable slotted wire harness removal pliers for reduced frictional resistance

Abstract

The invention discloses a movable trough-type wire harness removal pliers capable of reducing frictional resistance, which comprises two pliers body units arranged symmetrically; The third shaft section, the second shaft section, and the first shaft section; the second shaft section is provided with a ball bearing, and the ball bearing is in contact with the first shaft section; the balls of the ball bearing are exposed from the ball bearing and are in contact with the mobile bracket; The pliers body is connected with the first shaft section; the moving bracket is provided with a moving slot, the third shaft section of the installation shaft passes through the moving slot and is fixed by a lock nut, and the second shaft section can rotate in the moving slot. The invention can not only disassemble the wiring harness conveniently in a small space, but also reduce the torsional moment received by the joint of the wiring harness, and avoid the joints and corresponding interfaces of the wiring harness from being easily damaged due to the repeated large torsional moment on the joint of the wiring harness The problem.

Description

technical field [0001] The invention relates to a pair of pliers, in particular to a movable groove type wire harness removal pliers capable of reducing frictional resistance. Background technique [0002] In the development process of new energy vehicle chassis, many high and low voltage wiring harnesses are usually involved. This type of wire harness is usually hard, with a thick diameter, large bending radius, and large connector size. It also takes up a lot of space in the increasingly integrated car chassis, so it is quite inconvenient to install and remove the wire harness. Especially during disassembly, the disassembly space is small, the joint is not easy to disassemble, and the wiring harness is easy to be folded. The currently used tool for installing and disassembling the wire harness is a wire remover, which has two cross-hinged pliers arms, which are used to clamp the joints of the wire harness through the mutual rotation of the pliers arms, and then directly p...

Problems solved by technology

Although this structure is convenient to apply force in a place with small space, since the distance from the jaws of the pneumatic pressure clamp to the center of the prying (where the magnet is located) is constant, the harness connector is under pneumatic pressure through the pneumatic pressure clamp of the reference file. In the process of disassembling the connector by prying the connector with the pliers, in addition to the force in the plugging direction, the clamped connector also receives a large force in the non-plugging direction, forming a large torsional moment. The connectors and corresponding interfaces of the wiring harness Repeated plugging and unplugging under the action of such a large torsion torque is easy to cause damage to the harness connector and the corresponding interface

like figure 1 As shown, the force F in the figure is the force exerted by the folding wire pliers 15 on the joint 16 of the wire harness, which has a component F1 along the plugging direction of the joint and a component F2 perpendicular to the plugging direction. The distance of the rotation center is constant, and the component F2 of the force F is relatively large, so that the connector 16 of the wire harness is subject to a large torque, which is easy to cause damage to the wire harness connector 16 and the corresponding interface 17
