Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness sheath detection, and in particular relates to a wire harness sheath detection jig. Background Art

[0002] Wire harness sheath is a component used to protect wire harnesses. It has the functions of mechanical protection, environmental protection and electrical insulation. Its material is mostly rubber sheath or plastic sheath. It is used in the automotive industry, electronic and electrical industry and industrial automation field. In order to ensure the quality of wire harness sheath, its air tightness needs to be tested during its production.

[0003] At present, when testing the air tightness of wire harness sheaths, most of the methods used are to let air into the wire harness sheaths and then place the wire harness sheaths in water to observe whether bubbles emerge. For example, patent application number 202322167097.2 discloses an air tightness testing device for automobile wire harness sheaths. This patent inserts the wire harness sheath into the placement hole, then plugs the through hole above the wire harness sheath with a plug, and installs a frame plate on the upper end of the pad so that the upper and lower parts of the wire harness sheath are separated, thereby simulating the wire harness sheaths used in automobiles. Water is added to immerse the upper part of the wire harness sheath in water to detect whether water leaks to the bottom of the frame plate. However, using this method, on the one hand, different sizes of plugs are needed to seal the through holes of wire harness sheaths of different diameters, which is more troublesome to operate. On the other hand, since the size of the placement hole is fixed, wire harness sheaths of different diameters will become loose after being inserted into the placement hole, and the stability in use is poor.

When in use, it is only necessary to connect the two ends of the wire harness sheath to the two wire harness sheath connectors. It is more convenient to use and suitable for the installation of wire harness sheaths of different diameters. The operation is simpler. By setting a limiting mechanism, the wire harness sheath installed on the wire harness sheath connector can be fixed to avoid the wire harness sheath from loosening during detection, thereby improving the stability of use.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0012] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

Therefore, they cannot be understood as limitations on the present invention. Example

[0014] See attached Figure 1-2 As shown, a wire harness sheath detection fixture includes a base 1; two left-right symmetrical vertical plates 2 are fixed on the upper side of the base 1, and a wire harness sheath connector 3 is fixed on the inner side of the vertical plates 2. The inner ends of the wire harness sheath connectors 3 are tapered structures that gradually shrink from the outside to the inside, and the insides of the wire harness sheath connectors 3 are provided with air ducts. An exhaust pump 4 connected to the air duct of the wire harness sheath connector 3 is installed on the left side of the left end vertical plate 2, and an exhaust pipe 5 is installed at the exhaust port of the exhaust pump 4. The right side of the right end vertical plate 2 is provided with an exhaust pipe 5. It is equipped with an intake pump 6 connected to the air duct of the wiring harness sheath connector 3, and an intake pipe 7 is installed at the air inlet of the intake pump 6. A limiting mechanism 8 is provided on the inner side of the vertical plate 2. By setting the wiring harness sheath connector 3 with an air duct in the middle, and the inner ends of the wiring harness sheath connector 3 are all tapered structures that gradually shrink from the outside to the inside, when in use, it is only necessary to connect the two ends of the wiring harness sheath to the two wiring harness sheath connectors 3, which is more convenient to use, suitable for the installation of wiring harness sheaths of different diameters, and simpler to operate.

[0015] The limiting mechanism 8 includes a hydraulic cylinder 81, a fixing rod 82 and a pressure ring 83. The inner side of the vertical plate 2 is provided with a hydraulic cylinder 81 located directly below the wire harness sheath connector 3. The telescopic end of the hydraulic cylinder 81 is fixed with a fixing rod 82, and the upper end of the fixing rod 82 is fixed with a pressure ring 83. The pressure ring 83 and the tapered portion of the wire harness sheath connector 3 are located in the same horizontal plane. By setting the limiting mechanism 8, the wire harness sheath installed on the wire harness sheath connector 3 can be fixed to avoid the wire harness sheath from loosening during detection, thereby improving the stability of use.

[0016] Working principle: The two ends of the wiring harness sheath to be tested are respectively sleeved on the wiring harness sheath connector 3. Since the wiring harness sheath connector 3 is provided with an air duct inside, and the inner end of the wiring harness sheath connector 3 is a tapered structure that gradually shrinks from the outside to the inside, when in use, it is only necessary to connect the two ends of the wiring harness sheath to the two wiring harness sheath connectors 3. It is more convenient to use and suitable for the installation of wiring harness sheaths of different diameters. The operation is simpler. The hydraulic cylinder 81 contracts, thereby driving the pressure ring 83 to move through the fixing rod 82, and the wiring harness sheath is further fixed to the tapered part of the wiring harness sheath connector 3 through the pressure ring 83 to avoid loosening of the wiring harness sheath during detection and improve the stability of use. The air intake pump 6 is turned on and the exhaust pump 4 is turned off. After a certain amount of external air is introduced into the wiring harness sheath, the air intake pump 6 is turned off, and then the entire fixture is placed in the water tank to observe whether there are bubbles. If there are bubbles, it proves that the air tightness of the wiring harness sheath is unqualified.
