Description

Technical Field

[0001] The utility model relates to the technical field of wire harness conduction testing, in particular to a wire harness conduction testing device with a self-locking function. Background Technique

[0002] The wire harness conduction detection test is an inspection item to ensure the quality and reliability of the wire harness. Through the conduction table, unqualified products such as open circuits, short circuits, and misalignments in the wire harness can be detected, and the test is an important line of defense for quality assurance.

[0003] Currently, for the device used for wire harness conduction testing, the airtightness test of the wire harness is often carried out by means of externally wrapping and sealing the plugs and the wire core ends at both ends of the wire harness. However, simply placing the wire harness on the conduction testing device cannot ensure the accurate and tight insertion of the externally wrapped test end to the plug and the wire core. In addition, when encountering a wire harness that fails the test, some conduction testing devices do not have a self-locking function, resulting in that the operator can easily take out and classify the unqualified wire harness like other qualified wire harnesses, reducing the use effect of the conduction testing device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wire harness conduction testing device with a self-locking function, which solves the technical problems proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A wire harness conduction testing device with a self-locking function, including a testing instrument, one side of the testing instrument is connected with a bottom frame plate placed flat on the testing table, the center of the vertical surface on one side of the bottom frame plate is fixedly installed with a first hydraulic cylinder, the output end of the first hydraulic cylinder is fixedly connected with a horizontal pushing plate, symmetric plug outer wrapping sealing parts and wire core outer wrapping sealing parts for airtightness testing are fixedly installed on one side surface of the horizontal pushing plate, symmetric first placement seats and second placement seats are fixedly installed on the upper surface of the other side of the bottom frame plate, plugs and wire core heads that are externally wrapped and connected by the plug outer wrapping sealing parts and the wire core outer wrapping sealing parts are respectively inserted and placed in the first placement seats and the second placement seats, a wire harness is fixedly connected between the plug and the wire core head, a vertical frame is fixedly connected to the other side of the bottom frame plate, a second hydraulic cylinder is fixedly installed on the lower surface of the vertical frame, the output end of the second hydraulic cylinder is fixedly connected with a vertical pushing plate, and a first upper clamping seat and a second upper clamping seat that are clamped and abutted against the first placement seat and the second placement seat and provide self-locking are fixedly installed on the lower surface of the vertical pushing plate.

[0006] Optionally, one ends of the plug and the wire core head close to the first hydraulic cylinder are respectively inserted and connected to the internal test ends of the plug outer wrapping sealing part and the wire core outer wrapping sealing part.

[0007] Optionally, a through groove is formed through the surface of the chassis plate close to the first hydraulic cylinder. A set of symmetric sliding grooves are formed on the inner walls on both sides of the through groove. A sliding member is slidably connected in the sliding groove, and both of the two sliding members are fixedly connected to the lower surface of the horizontal pushing plate.

[0008] Optionally, a connecting movable plate is fixedly connected between the sliding members.

[0009] Optionally, a fixing rod is fixedly connected between the inner walls on the other two sides of the through groove, and the center of the connecting movable plate is sleeved and slid on the outside of the fixing rod.

Then, start the second hydraulic cylinder. The output end of the second hydraulic cylinder pushes the vertical pushing plate to displace downward. The vertical pushing plate drives the first upper clamping seat and the second upper clamping seat until they are clamped on the upper surfaces of the first placement seat and the second placement seat, so as to ensure the stability of the plug and the wire core head placed in the interiors of the first placement seat and the second placement seat. Subsequently, start the first hydraulic cylinder. The output end of the first hydraulic cylinder pushes the plug outer wrapping sealing member and the wire core outer wrapping sealing member of the horizontal pushing plate to be close to and inserted and connected in an outer wrapping manner outside the plug and the wire core head. Start the testing instrument to conduct an airtightness test on the wire harness. Finally, if an unqualified wire harness is encountered, the first hydraulic cylinder and the second hydraulic cylinder will enter a self-locking state; if a qualified wire harness is encountered, the first hydraulic cylinder and the second hydraulic cylinder will be automatically started to enable the plug and the wire core head to be taken out, thereby improving the use effect of the conduction testing device.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention. Embodiment

[0019] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a wire harness conduction test device with a self-locking function, including a test instrument 1. One side of the test instrument 1 is connected to a chassis plate 2 placed flat on the test bench. The center of the vertical surface on one side of the chassis plate 2 is fixedly installed with a first hydraulic cylinder 3. The output end of the first hydraulic cylinder 3 is fixedly connected to a horizontal push plate 4. On one side surface of the horizontal push plate 4, symmetric plug outer sealing members 5 and wire core outer sealing members 6 for airtightness testing are fixedly installed. On the upper surface of the other side of the chassis plate 2, symmetric first placement seats 12 and second placement seats 13 are fixedly installed. Inside the first placement seat 12 and the second placement seat 13, a plug 14 and a wire core head 15 that are externally connected by the plug outer sealing member 5 and the wire core outer sealing member 6 are respectively inserted and placed. One ends of the plug 14 and the wire core head 15 close to the first hydraulic cylinder 3 are respectively inserted and connected to the internal test ends of the plug outer sealing member 5 and the wire core outer sealing member 6. A wire harness 16 is fixedly connected between the plug 14 and the wire core head 15. The other side of the chassis plate 2 is fixedly connected to a vertical frame 17. The lower surface of the vertical frame 17 is fixedly installed with a second hydraulic cylinder 18. The output end of the second hydraulic cylinder 18 is fixedly connected to a vertical push plate 19. On the lower surface of the vertical push plate 19, a first upper clamping seat 20 and a second upper clamping seat 21 that are clamped and abutted against the first placement seat 12 and the second placement seat 13 and provide self-locking are fixedly installed.

[0020] More specifically, in this embodiment, first, the operator can respectively insert and place the plug 14 of the wire harness 16 and the core head 15 into the inside of the first placement seat 12 and the second placement seat 13. Then, start the second hydraulic cylinder 18. The output end of the second hydraulic cylinder 18 pushes the vertical push plate 19 to displace downward. The vertical push plate 19 drives the first upper clamping seat 20 and the second upper clamping seat 21 until they are clamped against the upper surfaces of the first placement seat 12 and the second placement seat 13, so as to ensure the stability of the plug 14 and the core head 15 placed inside the first placement seat 12 and the second placement seat 13. Subsequently, start the first hydraulic cylinder 3. The output end of the first hydraulic cylinder 3 pushes the plug outer sealing member 5 and the core outer sealing member 6 of the cross push plate 4 to approach and be inserted and connected in an outer wrapping manner outside the plug 14 and the core head 15. Start the test instrument 1 to perform an airtightness test on the wire harness 16. Finally, if the unqualified wire harness 16 is encountered, the first hydraulic cylinder 3 and the second hydraulic cylinder 18 will enter the self-locking state; if the qualified wire harness 16 is encountered, the first hydraulic cylinder 3 and the second hydraulic cylinder 18 will be automatically started, so that the plug 14 and the core head 15 can be taken out, thereby improving the use effect of the conduction test device.

[0021] Furthermore, on one side surface of the first placement seat 12 and the second placement seat 13, bottom clamping plates 22 with different heights are fixedly connected. On one side surface of the first upper clamping seat 20 and the second upper clamping seat 21, upper cover plates 23 with different heights are fixedly connected. The bottom clamping plates 22 and the upper cover plates 23 are respectively clamped against the upper and lower surfaces of the plug outer sealing member 5 and the core outer sealing member 6.

[0022] It should be noted that when the output end of the first hydraulic cylinder 3 pushes the plug outer sealing member 5 and the core outer sealing member 6 of the cross push plate 4 to approach and be inserted and connected in an outer wrapping manner outside the plug 14 and the core head 15, the connecting ends of the plug outer sealing member 5 and the core outer sealing member 6 will be stably inserted into the insertion groove formed by the bottom clamping plate 22 and the upper cover plate 23.

[0023] Embodiment 2, on the basis of the above embodiment:

[0024] Further, a through groove 7 is penetrated through the surface of the bottom frame plate 2 close to the first hydraulic cylinder 3. A group of symmetric sliding grooves 8 are opened on the inner walls of both sides of the through groove 7. A sliding member 9 is slidably connected in the sliding groove 8, and both sliding members 9 are fixedly connected to the lower surface of the cross push plate 4. A connecting movable plate 10 is fixedly connected between the sliding members 9. A fixing rod 11 is fixedly connected between the inner walls of the other two sides of the through groove 7, and the center of the connecting movable plate 10 is sleeved and slid on the outside of the fixing rod 11.

[0025] More specifically, in this embodiment, when the horizontal pushing plate 4 is driven by the first hydraulic cylinder 3, it will also synchronously drive the sliding member 9 and the connecting movable plate 10 to perform sliding displacement. The sliding member 9 slides inside the sliding groove 8, and the connecting movable plate 10 is sleeved and slides outside the fixed rod 11, so as to ensure the accurate stability of the plug outer sealing member 5 and the wire core outer sealing member 6 being externally inserted and connected to the plug 14 and the wire core head 15 from multiple aspects.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
