Description

Technical Field

[0001] The utility model relates to the technical field of connecting wire harnesses, in particular to a vehicle-mounted connecting wire harness with a self-detection function. Background Art

[0002] The automotive wiring harness is the network body of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the connection terminal (connector) made of copper material, which is crimped with the wires and cables, and then the insulator is plastic-pressed on the outside or an external metal shell is added. The wiring harness is bundled to form a component connecting the circuit. The existing automotive wiring harnesses are mostly connected through the connection terminals, and connected to the equipment through the buckles on the connection terminals. When the car is driving on a bumpy road, the vibration amplitude is large, and the connection terminals will loosen or even fall off, causing the wiring harness to be disconnected. The traditional automotive wiring harness is only connected by buckles and does not have a self-detection function. When the connection terminal is loose and falls off, it cannot provide feedback in time. After the wiring harness works at high intensity, the temperature of the wiring harness rises sharply, and an early warning cannot be issued in time, posing a safety hazard. For this reason, we propose an on-board connection wiring harness with a self-detection function. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are: the vehicle-mounted connection harness with self-detection function has the following advantages:

[0015] 1. Insert all the plugs into the socket, and rotate the knob forward ninety degrees. As the knob deflects, the lower end of the knob presses the rear end of the extrusion block, causing the extrusion block to move forward, and the second spring is compressed. As the extrusion block moves forward, the inclined surface 1 at the front end of the extrusion block continuously squeezes the inclined surface 2 at the middle of the inner end of the connecting block, causing the two connecting blocks to move outward synchronously, and the locking block and the limit column also move outward synchronously. The first spring is compressed. At this time, the locking block and the limit column protrude from the mounting block and enter the corresponding locking port at the device socket, and the wiring harness is fixed. At the same time, as the knob deflects, the upper end of the knob slowly contacts the front end of the anti-loosening ring, pressing the anti-loosening ring to move backward, and the reed undergoes elastic deformation until the knob deflects to a suitable position. The upper end of the knob is aligned with the groove, the spring leaf rebounds without force, and moves forward with the anti-loosening ring. At the same time, the groove clamps the knob to prevent the knob from shaking and causing the wiring harness to loosen. When the wiring harness needs to be disassembled for inspection, just deflect the knob backward ninety degrees, the knob presses the anti-loosening ring to move backward, and the spring leaf undergoes elastic deformation until the upper end of the knob leaves the inside of the groove. At this time, the knob loses restriction. At the same time, the lower end of the knob leaves the rear end of the extrusion block, and spring two drives the extrusion block backward without force. Inclined surface one leaves the surface of inclined surface two, and spring one drives the connecting block back to its original position without force. The locking block and the limit column also return to the inside of the mounting block synchronously. At this time, the wiring harness loses restriction and can be easily pulled out. It can be quickly installed and disassembled, which is convenient for inspection.

[0016] 2. When the wiring harness becomes loose, as the plug loosens backward, the distance between the mounting block and the surface of the equipment becomes larger, and spring three expands without force, driving the pressure ring and the connecting leg forward, and contact head one contacts the surface of contact head two. At this time, the circuit forms a path, and the external controller issues an early warning. When the temperature of the wiring harness is too high, the temperature sensor converts the temperature into an electrical signal and sends it to the external sensor. The external sensor issues an early warning, which can effectively avoid safety hazards caused by wiring harness failure. There is also a high temperature and loose loosening early warning mechanism. When the wiring harness is abnormal, it can be detected and reminded in time, which greatly reduces the occurrence of safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The working principle of a vehicle-mounted connection harness with a self-detection function provided by the utility model is as follows: when connecting the harness, the plug 2 is inserted into the socket of the device. As the plug 2 is inserted, the front end of the pressure ring 51 contacts the surface of the device. As the plug 2 continues to be inserted, the pressure ring 51 moves backward with the connecting leg 53, and the spring three 54 is compressed by force, and the contact one 55 leaves the surface of the contact head two 56. At this time, the plug 2 is fully inserted into the socket, and the knob 49 is rotated forward ninety degrees. As the knob 49 deviates, the lower end of the knob 49 presses the rear end of the extrusion block 463, so that the extrusion block 463 moves forward, and the spring two 462 is compressed by force. As the extrusion block 463 moves forward, the extrusion block 463 moves forward. The inclined surface 1 at the end continuously squeezes the inclined surface 2 at the middle of the inner end of the connecting block 42, so that the two connecting blocks 42 move outward synchronously, and the locking block 43 and the limiting column 44 also move outward synchronously, and the spring 1 45 is compressed by force. At this time, the locking block 43 and the limiting column 44 protrude out of the mounting block 1 and enter the corresponding locking hole at the device socket, and the wiring harness is fixed. At the same time, with the deflection of the knob 49, the upper end of the knob 49 slowly contacts the front end of the anti-loosening ring 471, pressing the anti-loosening ring 471 to move backward, and the spring leaf 472 undergoes elastic deformation until the knob 49 deflects to the appropriate position, and the upper end of the knob 49 is aligned with the groove 473. The spring leaf 472 rebounds without force, and moves the anti-loosening ring 471 forward. At the same time, the groove 47 3. Lock the knob 49 to prevent the knob 49 from shaking and causing the wiring harness to loosen. When the wiring harness loosens after the car has gone through a strong bump, as the plug 2 loosens backward, the distance between the mounting block 1 and the surface of the equipment increases, and the spring 3 54 expands without force, driving the pressure ring 51 and the connecting leg 53 to move forward, and the contact head 1 55 contacts the surface of the contact head 2 56. At this time, the circuit forms a path, and the external controller issues an early warning. When the temperature of the wiring harness is too high, the temperature sensor 6 converts the temperature into an electrical signal and sends it to the external sensor. The external sensor issues an early warning, which can effectively avoid safety hazards caused by wiring harness failure. When the wiring harness needs to be disassembled for maintenance, it is only necessary to deflect the knob backward by ninety degrees, and the knob 49 presses the anti-loosening ring 4 71 moves backward, and the spring sheet 472 undergoes elastic deformation until the upper end of the knob 49 leaves the inside of the groove 473. At this time, the knob loses its restriction. At the same time, the lower end of the knob 49 leaves the rear end of the extrusion block 463, and the spring second 462 drives the extrusion block 463 to move backward without force. The inclined surface one leaves the surface of the inclined surface two, and the spring one 45 drives the connecting block 42 back to its original position without force. The locking block 43 and the limiting column 44 also synchronously return to the inside of the mounting block 1. At this time, the wiring harness loses its restriction and can be easily pulled out. It can be quickly installed and disassembled, which is convenient for maintenance. A high temperature and loose movement falling-off warning mechanism is also provided. When an abnormal situation occurs in the wiring harness, it can be detected and reminded in time, which greatly reduces the occurrence of safety hazards.
