Description

Technical Field

[0001] The utility model relates to the field of instantaneous break detection devices, in particular to an automobile wiring harness instantaneous break detection device. Background Art

[0002] An automotive wiring harness is a component that is formed by crimping contact terminals (connectors) made of copper material with wires and cables, and then plastic-pressing an insulator or adding a metal shell to the outside to form a connecting circuit.

[0003] During the automotive wiring harness production process, transient disconnect detection is required. A transient disconnect detection device typically applies a certain current or voltage to the harness under test and monitors the current and voltage changes at the harness endpoints. When a transient disconnect occurs in a dynamic environment such as vibration, the device detects this change and uses an internal algorithm to calculate the location and time of the disconnect. Detecting transient disconnects in automotive wiring harnesses is crucial to ensuring their reliability and safety.

[0004] Existing automotive wiring harness instantaneous break detection devices are mostly placed on a desktop when in use. Since the instantaneous break detection device is a precision electronic instrument, when it is moved, the speed of descent is too fast, which will increase its vibration amplitude and cause damage to internal parts. It must be handled with care, making it inconvenient to move.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0009] Furthermore, four fixed tubes are provided, and the fixed tubes are distributed in a rectangular array at the bottom of the instantaneous interrupter.

[0010] Furthermore, the piston is slidably mounted in the inner cavity of the suction cup.

[0023] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0024] like Figures 1 to 5 As shown, the utility model is a vehicle wiring harness instantaneous break detection device, comprising: an instantaneous break instrument 1, a vibration plate 13, a protection mechanism for protecting the instantaneous break instrument 1 when not in use, and a buffer mechanism for buffering the instantaneous break instrument 1 when placed.

[0025] When performing a momentary disconnection test on an automobile wiring harness, the wire connections of the two automobile wiring harnesses are placed on a vibration disk 13 for vibration. At the same time, the other ends of the two automobile wiring harnesses are connected to a momentary disconnection meter 1. The momentary disconnection meter 1 detects the current and voltage changes at the wire connections of the two automobile wiring harnesses. When the automobile wiring harness suffers a momentary power outage in a dynamic environment such as vibration, the momentary disconnection meter 1 will capture this change and calculate the location and time of the momentary disconnection through an internal algorithm.

[0026] The buffer mechanism includes: a fixed tube 8 fixedly installed at the bottom of the instantaneous interrupter 1, four fixed tubes 8 are provided, and several fixed tubes 8 are distributed in a rectangular array at the bottom of the instantaneous interrupter 1, a suction cup 9 movably installed in the inner cavity of the fixed tube 8, a fixed rod 10 fixedly installed on the inner wall of the fixed tube 8, a piston 11 fixedly installed at one end of the fixed rod 10, the piston 11 is slidably installed in the inner cavity of the suction cup 9, and a reset spring 12 drives the suction cup 9 to reset, one end of the reset spring 12 is fixedly connected to the inner wall of the fixed tube 8, and the other end of the reset spring 12 is fixedly connected to the suction cup 9.

[0027] When the instantaneous interrupter 1 is placed on the table, the suction cup 9 is first subjected to force, and the return spring 12 connected to the suction cup 9 undergoes elastic deformation, reducing the impact force, thereby providing a buffering protection for the instantaneous interrupter 1, avoiding the problem that the instantaneous interrupter 1 descends too fast when being moved, which increases its vibration amplitude and causes damage to internal parts.

[0028] Since the instantaneous interrupter 1 moves downward, it can drive the fixed tube 8 to move downward, and the fixed tube 8 drives the fixed rod 10 to move downward, and the fixed rod 10 drives the piston 11 to move downward, so that the air in the suction cup 9 can be squeezed out, so that the suction cup 9 is tightly adsorbed on the desktop, which plays a role in fixing the instantaneous interrupter 1, thereby preventing the instantaneous interrupter 1 from sliding during use and improving the stability of the instantaneous interrupter 1.

[0029] In the present application, the setting of the buffer mechanism can, on the one hand, play a role of buffering protection for the instantaneous interrupter 1, thereby preventing the instantaneous interrupter 1 from descending too fast when being moved, which would increase its vibration amplitude and cause damage to internal parts; on the other hand, it plays a role of fixing the instantaneous interrupter 1, thereby preventing the instantaneous interrupter 1 from sliding during use, thereby improving the stability of the instantaneous interrupter 1.

[0030] The protective mechanism includes: a protective cover 2 hingedly mounted on the instantaneous interrupter 1, a torsion spring installed at the hinge between the protective cover 2 and the instantaneous interrupter 1, and a fixing component for fixing the protective cover 2 after it is opened, and the fixing component includes: a connecting plate 3 fixedly mounted on the protective cover 2, a fixing frame 4 fixedly mounted on the instantaneous interrupter 1, a movable rod 5 installed on the fixing frame 4, a connecting block 6 fixedly mounted on one end of the movable rod 5, and a linkage spring 7 sleeved on the movable rod 5, one end of the linkage spring 7 being fixedly connected to the fixing frame 4, and the other end of the linkage spring 7 being fixedly connected to the connecting block 6.

[0031] By setting the protective cover 2, the operating surface of the instantaneous interrupter 1 can be covered when the instantaneous interrupter 1 is not in use, thereby playing a role in dust protection. When in use, first pull the connecting block 6, and the connecting block 6 drives the movable rod 5 to move, thereby driving the linkage spring 7 to stretch. At this time, the protective cover 2 is opened, so that the protective cover 2 rotates at its hinge with the instantaneous interrupter 1. At this time, the connecting plate 3 rotates with the rotation of the protective cover 2. When the connecting plate 3 rotates to the inside of the fixing frame 4 and is located below the movable rod 5, by loosening the connecting block 6, the movable rod 5 can be driven to reset by the elastic force of the linkage spring 7, thereby limiting the connecting plate 3, and then fixing the opened protective cover 2, which makes it convenient to use the instantaneous interrupter 1.

[0032] Working principle: During use, when the instantaneous interrupter 1 is placed on the desktop, the suction cup 9 is first subjected to force, and the return spring 12 connected to the suction cup 9 undergoes elastic deformation to reduce the impact force, thereby playing a buffering and protective role for the instantaneous interrupter 1, and avoiding the problem that the instantaneous interrupter 1 descends too fast when being moved, which will increase its vibration amplitude and cause damage to internal parts; since the instantaneous interrupter 1 moves downward, it can drive the fixed tube 8 to move downward, and the fixed rod 10 drives the piston 11 to move downward, thereby squeezing out the air in the suction cup 9, so that the suction cup 9 is tightly adsorbed on the desktop, which plays a fixing role for the instantaneous interrupter 1, thereby avoiding the instantaneous interrupter 1 from sliding during use, and improving the stability of the instantaneous interrupter 1.
