[0002] The wiring harness is a group of metal wires and cables tied together. It is used to connect signals and power between carrying equipment. It is the wiring component that connects various electrical devices in the automotive circuit. It consists of an insulating sheath, wiring terminals, wires, and insulating wrapping materials.

[0003] At present, when testing the air tightness of the wiring harness ends, the wiring harness ends are first placed in the lower mold, and then the upper mold and the lower mold are merged, and then the air tightness of the wiring harness ends is tested by inflation. During and after the test, the wiring harness ends need to be picked up and placed, and the lower mold is located at the bottom of the upper mold. In the case of loss of control of the hydraulic cylinder, the upper mold may be easily pressed down, causing damage to the staff.

[0004] Therefore, it is necessary to invent a wire harness airtight fixture to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire harness airtight fixture, comprising a testing platform, the top of the testing platform is connected to two fixed rods, the tops of the two fixed rods are commonly connected to a top plate, the top of the top plate is connected to a hydraulic cylinder, the bottom of the hydraulic cylinder is connected to a push plate, the surface of the push plate is provided with limiting holes corresponding to the fixed rods, the bottom of the push plate is connected to an upper mold, the left side of the upper mold is connected to a push rod, the other end of the push rod is connected to a pull rod, the other end of the pull rod is connected to a cross plate, the side wall of the cross plate is connected to a first spring, the other end of the first spring is connected to a lower mold, the bottom of the lower mold is connected to a slider, and the top of the testing platform is provided with a slide groove corresponding to the slider.

[0007] Preferably, the outer walls of the two fixing rods are each provided with a second spring, and the top end of the second spring abuts against the bottom end of the pushing plate.

[0008] Preferably, the side wall of the lower mold is connected to a limiting rod, the side walls of the pull rod and the cross plate are provided with limiting grooves corresponding to the limiting rod, and the first spring is located on the outside of the limiting rod.

[0009] Preferably, the bottom of the pull rod is connected with a stabilizing block, and the stabilizing block is slidably arranged with the top of the detection platform.

[0011] Technical effects and advantages of the utility model:

[0012] The push plate is pushed by using a hydraulic cylinder, and the push plate pushes the upper mold. When the upper mold is pressed down, the push rod is squeezed by the push rod, so that the pull rod moves to the left, and the pull rod pulls the cross plate. The cross plate pulls the lower mold through the first spring. The pulling force at this time is less than the elastic force of the first spring. The lower mold pulls the slider to make the slider slide in the slide groove. When the slider is against the leftmost side of the slide groove, the slider limits the lower mold. At this time, the lower mold is at the bottom of the upper mold, and the upper mold continues to be pressed down. At this time, the pull rod pulls the first spring, so the lower mold will not continue to shift. The upper mold and the lower mold are sealed, and the air tightness of the wiring harness head can be tested. Otherwise, the lower mold is pushed out to make the lower mold away from the upper mold, so that the wiring harness in the lower mold can be taken and placed, which can effectively improve the safety of the user.
