Description

Technical Field

[0001] The utility model relates to the technical field of wire harness detection, in particular to a wire harness waterproofness detection test box. Background Art

[0002] The wiring harness is an essential part for signal transmission of electrical equipment. It is generally composed of connectors and wires. Since the wires are made of rubber, their waterproofness is relatively stable. However, connectors are needed to connect the two wiring harnesses. Since there is a gap between the connectors of the two wiring harnesses, their sealing performance needs to be tested to ensure better waterproofness.

[0003] Existing testing methods for wiring harness waterproofness generally use a test chamber. After the two wiring harness connectors are plugged in, they are placed inside the test chamber. Water is then sprayed on the two connector ends to determine waterproofness based on whether the wiring harness is short-circuited. If the two wiring harnesses are short-circuited, the closed circuit of the wiring harness stops working. However, in actual testing, it was found that the spraying water can only spray the surfaces of the two connectors, and the two sides and bottom surfaces of the two connectors cannot be effectively sprayed with water, which can lead to errors in the waterproofness test of the wiring harness connectors. Moreover, common test chambers cannot recycle and reuse the water after testing, which is not energy-saving and environmentally friendly. To this end, a test chamber for wiring harness waterproofness testing is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised by the background technology in the prior art, and to propose a wire harness waterproofness detection test box.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A wiring harness waterproofness detection test box comprises an upper box body and a lower box body, both sides of the upper box body and both sides of the lower box body are provided with threading holes, and both sides of the upper box body and both sides of the lower box body are provided with lifting mechanisms; the interior of the upper box body and the interior of the lower box body are respectively provided with an upper spray plate and a lower spray plate, the upper spray plate and the upper box body, as well as the lower spray plate and the lower box body are fixedly connected by fixing rods, the upper spray plate and the lower spray plate both adopt a hollow structure, and the inner side walls of the upper spray plate and the lower spray plate are provided with a plurality of evenly distributed spray holes, a water lifting pump is fixedly provided inside the lower box body, and the output end of the water lifting pump is fixedly provided with a lifting pipe connected to the upper spray plate and the lower spray plate.

[0007] Preferably, rubber protective pads are fixedly provided inside the two threading openings, and a wiring harness is passed through the inside of the rubber protective pads. The connectors of the two wiring harnesses are plugged into each other and form a closed loop with the external powered equipment.

[0008] Preferably, the upper spray plate and the lower spray plate are respectively located on the upper and lower sides of the two wiring harness connectors, and both the upper spray plate and the lower spray plate are arc-shaped plates.

[0009] Preferably, the lifting mechanism includes an electric push rod, and the side walls of the upper box body and the side walls of the lower box body are fixedly provided with mounting seats, and the electric push rod is fixedly installed between the two mounting seats.

[0010] Preferably, a transparent glass observation window is fixedly embedded on the top of the upper box body.

[0011] Preferably, the lifting pipe is a PVC hose, and the lifting pipe has two branch pipes.

[0012] Compared with the existing technology, the utility model provides a wiring harness waterproofness detection test box, which has the following beneficial effects:

[0013] 1. The wiring harness waterproof test box is equipped with an upper spray plate, a lower spray plate, a spray hole, a water pump and a lifting pipe. When the lifting pump is turned on, the water inside the lower box body can be sucked into the lifting pipe, and then discharged into the interior of the upper spray plate and the interior of the lower spray plate respectively. Then it is sprayed out through multiple spray holes and sprayed around the two wiring connectors, so that both connectors can be fully sprayed. If the two wiring harnesses are short-circuited, the closed loop of the wiring harness stops working. At this time, it means that the waterproofness of the connectors of the two wiring harnesses is not good. On the contrary, it means that the waterproofness of the connectors of the two wiring harnesses is good, thereby improving the detection accuracy of the wiring harness waterproofness. The water after spraying will be automatically collected in the interior of the lower box body, thereby realizing the recycling of water.

[0014] 2. The wiring harness waterproofness test box controls the electric push rod set between the upper box and the lower box to extend and push the upper box upward, so that the upper box and the lower box are separated. At this time, the two connected wiring harnesses can be placed in the threading port and the upper and lower spray plates, making it easier for the test personnel to complete the test operation.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can perform a comprehensive spray test on the connectors of the wiring harness, so that the connectors of the wiring harness can be accurately tested for waterproofness. At the same time, it has the function of recycling water sources, which meets the requirements of energy conservation and environmental protection. In addition, the entire test operation is convenient and the detection efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS
