[0028] The present utility model will be further described below in conjunction with the embodiments shown in the drawings.

[0029] Embodiment 1: As shown in the appendix Figure 1 A portable electrical harness testing device for functionally detecting an electrical harness 14 includes a portable box 1, a testing body 2, and a power supply system 3.

[0030] The portable box 1 is generally rectangular in shape and may include a testing box for arranging the testing body 2 and a power supply box for arranging the power supply system 3, and the testing box and the power supply box are detachably connected.

[0031] On the portable box body 1, that is, on the upper surface of the test box body, a cavity for inserting the electrical wire harness 14 is provided. The test body 2 includes a locking mechanism 4, test probes 5, and a main control chip 6.

[0032] The locking mechanism 4 is arranged on the portable box body 1, that is, on the test box body, and is located on the side of the cavity. It is used to lock or unlock the electrical wire harness 14 inserted into the cavity. Therefore, the locking mechanism 4 has a locking state for locking the electrical wire harness 14 and an unlocking state for unlocking the electrical wire harness 14. As shown in the appendix Figure 2 to the appendix Figure 9As shown, the locking mechanism 4 includes a housing 7, a locking member 8, and a driving member 9, and also includes a first spring and a second spring (the first spring and the second spring are not shown in the figure). The housing 7 is connected to the portable box body 1 by a plurality of bolts 13, including a part for accommodating the locking member 8 and a part for accommodating the driving member 9. The locking member 8 is slidably connected to the housing 7, and one end of the locking member 8 forms a locking tongue 12 that can extend outside the housing 7 to lock the electrical wire harness 14. In this embodiment, the sliding direction of the locking member 8 is arranged in the horizontal direction, and the housing 7 is provided with a window for the locking tongue 12 to extend out, and this window corresponds to the upper part of the cavity side. The driving member 9 is also slidably connected to the housing 7 and is docked with the locking member 8, so that the driving member 9 can drive the locking member 8 to slide. In this embodiment, the sliding direction of the driving member 9 is arranged in the vertical direction, that is, the sliding direction of the locking member 8 is perpendicular to the sliding direction of the driving member 9. A driving hole is provided on the upper surface of the housing 7, and the driving member 9 is inserted through the driving hole. One end of the driving member 9, that is, the upper end, is located outside the housing 7, and the other end of the driving member 9, that is, the lower end, is located inside the housing 7. One end of the driving member 9 that is docked with the locking member 8, that is, the lower end of the driving member 9, is provided with a driving rod 10. In this embodiment, the lower end of the driving member 9 forms two connecting plates that are respectively arranged on both sides of the sliding direction of the locking member 8. Mounting holes are correspondingly provided on the connecting plates, and the driving rod 10 is inserted into the mounting holes and fixedly installed at the lower end of the driving member 9. A driving inclined surface 11 is provided on the locking member 8 and is inclined to its sliding direction. In this embodiment, the middle part of the locking member 8 is hollowed out and a slope is formed on one side of the hollowed-out part, and the inclination angle of this slope is about 45°. The driving rod 10 is in contact with the driving inclined surface 11, and can be in sliding contact or rolling contact. The first spring is used to realize the sliding reset of the locking member 8. The telescopic direction of the first spring is along the sliding direction of the locking member 8, that is, the horizontal direction, and the first spring is arranged between the housing 7 and the locking member 8. A first groove can be provided along the sliding direction at the other end of the locking member 8 that does not have the locking tongue 12, and a first protrusion is provided at the bottom of the first groove. One end of the first spring is sleeved on the first protrusion and then connected to the bottom of the first groove, so as to be connected to the locking member 8, and the other end of the first spring is fixed on the side wall of the housing 7 corresponding to the first groove. The second spring is used to realize the sliding reset of the driving member 9. The telescopic direction of the second spring is along the sliding direction of the driving member 9, that is, the vertical direction, and the second spring is arranged between the housing 7 and the driving member 9, and is arranged at one end of the driving member 9 located outside the housing 7. A second groove can be provided along the sliding direction at the top of the driving member 9, and a second protrusion is provided at the bottom of the second groove. At the same time, a positioning protrusion corresponding to the second groove is provided on the upper surface of the housing 7, and a positioning groove corresponding to the second protrusion is provided at the center of the positioning protrusion. One end of the second spring is sleeved on the second protrusion and then connected to the bottom of the second groove, and the other end of the second spring is fixed on the positioning protrusion.The lock tongue 12 has a triangular cross section and has an inclined surface facing the insertion direction of the electrical harness 14 , that is, the upper surface of the lock tongue 12 forms an inclined surface.

[0033] There are multiple test probes 5, which are arranged in a row in the portable box 1, that is, the test box, and correspond to the cavity. When the electrical harness 14 is inserted into the cavity and locked by the locking mechanism 4, the electrical harness 14 is connected to the upper end of the test probe 5, and the lower end of the test probe 5 is connected to the main control chip 6, thereby constructing a test loop.

[0034] The main control chip 6 is disposed in the portable box 1, namely the test box, and is used for controlling the implementation of functional testing and wireless networking communication.

[0035] The power supply system 3 is disposed in the portable box 1 , that is, in the power supply box, and the power supply system 3 is connected to the main control chip 6 .

[0036] As attached Figure 2 To Attachment Figure 5 As shown, the locking state of the locking mechanism 4 is its normal state, and the locking mechanism 4 is also in the locking state when the electrical wiring harness 14 is not inserted into the cavity. Compared with the state in which the electrical wiring harness 14 is inserted into the cavity and locked by the locking mechanism 4, the lock tongue 12 of the locking member 8 does not contact the electrical wiring harness 14 when the electrical wiring harness 14 is not inserted into the cavity. When the locking mechanism 4 is in the locked state, the driving member 9 is located at the upper limit position in the vertical direction, and the locking member 8 is located at the extension limit position in the horizontal direction. At this time, the driving rod 10 at the lower end of the driving member 9 is located near the upper end of the driving inclined surface 11 in the locking member 8. When the electrical wiring harness 14 is inserted into the cavity from top to bottom, it first contacts the inclined surface of the lock tongue 12 on the locking member 8, thereby pushing the lock tongue 12 to retract into the housing 7 and compressing the first spring, and the electrical wiring harness 14 passes over the lock tongue 12 and is inserted into the cavity. During this process, the lock tongue 12 of the locking member 8 is always in contact with the electrical wiring harness 14, so that after the electrical wiring harness 14 is inserted into place, its position can be locked by the lock tongue 12. The insertion locking of the electrical harness 14 can also be achieved by operating the driving member 9, that is, pressing the driving member 9 to slide downward and compress the second spring, and then the driving rod 10 pushes the driving inclined surface 11 to drive the locking member 8 to retract into the housing 7 and compress the first spring. When the driving member 9 is pressed to reach the lower limit position, as shown in the attached Figure 6 To Attachment Figure 9As shown, the locking mechanism 4 enters the unlocked state. At this time, the locking member 8 is at the retraction limit position in the horizontal direction, and the driving rod 10 at the lower end of the driving member 9 is near the lower end of the driving inclined surface 11 in the locking member 8. The locking tongue 12 leaves above the cavity, so the electrical harness 14 can be inserted. After the insertion, stop pressing the driving member 9, then under the action of the first spring and the second spring, the locking member 8 and the driving member 9 reset, thereby locking the position of the electrical harness 14 through the locking tongue 12. When the test of the electrical harness 14 is completed, press the driving member 9 to drive the locking member 8 to unlock the electrical harness 14, so that the electrical harness 14 can be taken out of the cavity.

[0037] Based on the above portable electrical harness testing device, a portable electrical harness testing system can be constructed. The portable electrical harness testing system includes the aforementioned portable electrical harness testing device and a remote testing platform that is wirelessly networked with the portable electrical harness testing device.

[0038] The above portable electrical harness testing device can solve the spatial limitation during the test of the electrical harness 14. It is easy to carry, convenient to install and use, and can achieve rapid testing. Regardless of the specifications of the electrical harness 14 itself, as long as it meets the networking conditions, rapid testing can be carried out. When the electrical harness 14 changes, only the test body 2 part needs to be replaced to continue the test.

[0039] The above embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
