Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] like figure 1 and figure 2 As shown, a wire harness resistance testing device under a constant temperature state includes a transmission chain 1 and a wire harness clamping device 3 fixed on the transmission chain 1 at equal intervals. An inverted trapezoidal guide block 2 is arranged above the transmission chain 1. A resistance testing device 4 for pressing down is arranged above the inverted trapezoidal guide block 2 .

[0018] By setting an inverted trapezoidal guide block 2 above the transmission chain 1, the wire harness clamping device 3 is pressed down when passing through the inverted trapezoidal guide block 2, so that the lower end of the wire harness extends into the thermostatic box below (not shown in the figure) ), at the same time, it is possible to control the time when the wire harness extends into the incubator by selecting the inverted trap...

Abstract

The invention discloses a device for testing wiring harness resistance under constant temperature state. The device comprises a transmission chain and wiring harness clamping devices fixed on the transmission chain at equal intervals, wherein a reversed-ladder-shaped guiding block is arranged above the transmission chain, and a downward-pressing resistance testing device is arranged above the reversed-ladder-shaped guiding block. The device for testing wiring harness resistance under constant temperature state solves the problem that under constant temperature state, wiring harness resistance testing temperature is difficult to control, clamping difficult is large, efficiency is low and reliability is not high. The reversed-ladder-shaped guiding block is arranged above the transmission chain, so that the wiring harness clamping device can be pressed downwards when passing the reversed-ladder-shaped guiding block, the lower end of wiring harness can extend into an under thermostat, and time for the wiring harness to extend into the thermostat can be controlled by selecting the reversed-ladder-shaped guiding block with different lengths. The reversed-ladder-shaped guiding block can ensure that the wiring harness can stay more than 30s in the thermostat, full-automatic mechanical testing can be achieved, testing efficiency is improved, and testing quality is ensured.

Description

technical field [0001] The invention relates to a wire harness resistance testing device, in particular to a wire harness resistance testing device under a constant temperature state. Background technique [0002] In modern cars, there are a lot of car wiring harnesses, and the electronic control system is closely related to the wiring harnesses. The automobile wiring harness is the network main body of the automobile circuit, which connects the electrical and electronic components of the automobile and enables them to function. Without the wiring harness, there is no automobile circuit. [0003] In order to ensure the quality of the wire harness, it is essential to test the performance of the wire harness before leaving the factory. The wire harness resistance parameter in a constant temperature environment is an important parameter index of the wire harness. The existing testing devices are usually manually tested one by one, which is not only inefficient, but also low in...
