Description

Wiring harness self-test amplifier device Technical Field

[0001] The utility model belongs to the technical field of wire harness self-inspection, and relates to a wire harness self-inspection amplification device. Background Art

[0002] The wiring harness is the overall service equipment for a certain group of load sources, such as relay lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship between traffic volume, call loss and wiring harness capacity. In modern cars, the electronic control system is closely related to the wiring harness. Someone once made a vivid metaphor: the microcomputer is equivalent to the human brain, the sensor is equivalent to the sensory organ, the actuator is equivalent to the motor tube, and the wiring harness is the nerve and blood vessel. From the functional point of view, the automotive wiring harness is divided into two types: power lines that carry power to drive the actuator (actuator) and signal lines that transmit sensor input instructions. According to the different structures, it is divided into full utilization wiring harness, partial utilization wiring harness and link system; according to the different service methods, it is divided into loss-controlled wiring harness and waiting-controlled wiring harness (see random service system); according to the different number of load sources served, it is divided into unlimited load source wiring harness and limited load source wiring harness.

[0003] After the production of existing wiring harnesses is completed, the wiring harness heads need to be inspected, mainly to detect wiring problems in the wiring harness heads to prevent the wires and connectors inside the wiring harness from being fully connected. The main detection method is for a staff member to stand in front of the detection device and clamp the wiring harness in the fixture on the machine. After the wiring harness is fixed, a frame equipped with a light ring is aligned with the wiring harness for inspection. However, due to the different sizes and types of wiring harnesses, magnifying glasses of different magnifications are required for observation and detection. Since the frame is fixed and cannot be adjusted at will, when detecting the wiring harness head, the position of the frame cannot be moved, so it cannot meet the staff's needs of using magnifying glasses of different magnifications for observation, which greatly reduces the work efficiency of the detection line speed.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] As shown in Figures 1-5, a wiring harness self-inspection and amplification device includes a main body 1, a base 2 is provided at the bottom of the main body 1, a support frame 3 is fixedly installed on the rear outer wall of the base 2, a mirror frame 4 is provided on the top of the support frame 3, a connecting seat 5 is installed on the upper part of the mirror frame 4, a connecting rod 51 is installed on the upper outer wall of the connecting seat 5, a lower mirror shell 41 and an upper mirror shell 42 are installed inside the mirror frame 4, a notch 43 penetrating the outer wall is provided on one side of the lower mirror shell 41, a light ring 421 is installed on the inner edge of the upper mirror shell 42, a slide rail 6 with a circular outer profile is installed on the inner wall of the lower mirror shell 41, a plurality of limit blocks 61 are installed in the middle of the slide rail 6, a spring 62 is installed on the outer wall of one side of the limit block 61, a fixing frame 7 is movably installed on the slide rail 6, and a slider 71 is installed on the outer wall of one side of the fixing frame 7.

[0027] In this embodiment, wires and buttons are installed on both sides of the connecting base 5. The buttons are used to control the opening and closing of the light ring 421, and the wires provide power to the light ring 421.

[0028] As shown in Figures 3 and 4 , the fixed frame 7 has a circular outline. A concave, annular inner groove 73 is defined on the outer wall of the fixed frame 7. A tooth block 72 is positioned on one side of the inner groove 73. The tooth blocks 72 and slider 71 are located on either side of the fixed frame 7. The inner groove 73 is centrally located between the outer wall of the fixed frame 7. A circular hollow is defined between the lower and upper mirror housings 41 and 42. A roller 8 is mounted in the notch 43. A gear 81 is coaxially mounted on the roller 8. The roller 8 is rotatably mounted to the inner wall of the lower mirror housing 41 via a slide rod. A portion of the roller 8 protrudes from the notch 43, exposed to the outside, while the remaining portion is embedded in the inner groove 73. A gap exists between the roller 8 and the inner wall of the inner groove 73. The tooth block 72 and the gear 81 installed on the fixing frame 7 are meshed with each other. A magnifying glass 9 is installed in the fixing frame 7, and a high-power lens 91 is installed inside the magnifying glass 9.

[0029] Specifically, through the mutual engagement of the gear 81 and the tooth block 72, when the finger moves the roller 8, since the gear 81 and the roller 8 are coaxially mounted on the outer wall of the lower mirror housing 41 through the slide rod, and there is a gap between the roller 8 and the inner wall of the inner groove 73, the rotation of the roller 8 will not hinder the fixed frame 7. Therefore, when the roller 8 is swung, the fixed frame 7 is driven by the gear 81 to make a circular motion along the slide rail 6 through the slider 71, so the magnifying glass 9 and the high-power lens 91 installed on the fixed frame 7 rotate accordingly, and the position of the high-power lens 91 relative to the human body changes, meeting the needs of the staff to use magnifying glasses 9 of different magnifications for observation.

[0030] As shown in Figures 2 and 3 , the fixing frame 7 is slidably mounted within the slide rail 6 via a slider 71. The spring 62 and the outer wall of the slider 71 are interconnected. The lower mirror housing 41 is provided with a plurality of threaded holes, through which the lower and upper mirror housings 41 and 42 are fixedly connected. A display 21 is mounted on the outer wall of the front face of the base 2. Clamps 22 are symmetrically mounted on the upper outer wall of the base 2. A serrated felt layer is provided on the outer wall corresponding to the clamps 22.

[0031] Specifically, the display 21 controls the clamp 22 to fix the middle wire harness on the machine base 2. A serrated felt layer is provided on the outer wall of the clamp 22. The serrations with the felt layer can effectively increase the friction between the wire harness and the clamp 22. At the same time, the felt layer can effectively prevent the clamp 22 from damaging the outer shell of the wire harness.

[0032] As shown in FIG1 , the support frame 3 has a U-shaped opening at the top, with clip ears 33 symmetrically mounted within the U-shaped opening. A rotating wheel 31 is mounted on the outer wall of one side of the U-shaped opening. A pin 32 is fixedly mounted on one side of the rotating wheel 31. The pin 32 extends through the outer wall of the U-shaped opening, with the end of the pin 32 abutting against the outer wall of the clip ear 33. The mirror frame 4 is mounted on the support frame 3 via a connecting rod 51 provided at the top, with the clip ears 33 inserted into the clip ears 33.

[0033] Specifically, the clamping ear 33 has a certain deformation function, so when the rotating wheel 31 is rotated, the pin 32 moves toward the inside of the U-shaped opening, so that the end of the pin 32 rests against the outer wall of the clamping ear 33, and the clamping ear 33 clamps the connecting rod 51, thereby fixing the connecting rod 51 to install the mirror frame 4 on the support frame 3.

[0034] The working principle of this utility model is:

[0035] Place the finished wire harness in the middle of the clamp 22, operate the display 21 to adjust the clamp 22 to fix the wire harness on the machine base 2, and be careful to prevent excessive support from damaging the wire harness in the middle.

[0036] By rotating the wheel 31, the pin 32 moves toward the inside of the U-shaped opening, so that the end of the pin 32 abuts against the outer wall of the clamping ear 33, and the clamping ear 33 clamps the connecting rod 51, thereby fixing the connecting rod 51 to install the frame 4 on the support frame 3. At the same time, the wheel 31 is rotated appropriately according to needs, and the position of the clamping ear 33 supporting the connecting rod 51 is appropriately adjusted to adjust the height of the frame 4.

[0037] Press the button on the right side of the connecting seat 5 to turn on the light ring 421 to provide sufficient lighting conditions for detecting the wiring harness. When the finger moves the roller 8, since the gear 81 and the roller 8 are coaxially installed on the outer wall of the lower mirror shell 41 through the slide rod, and there is a gap between the roller 8 and the inner wall of the inner groove 73, the rotation of the roller 8 will not hinder the fixed frame 7. Therefore, when the roller 8 is fluctuated, the gear 81 drives the fixed frame 7 to make a circular motion along the slide rail 6 through the slider 71, so the magnifying glass 9 and the high-power mirror 91 installed on the fixed frame 7 rotate accordingly, and the position of the high-power mirror 91 relative to the human body changes, meeting the needs of the staff to use magnifying glasses of different magnifications to observe 9.

[0038] When the fixing frame 7 moves along the slide rail 6, the internal spring 62 is deformed and generates elastic force. Since the two ends of the spring 62 are respectively connected to the slider 71 and the limit block 61, when the inspection is completed, the finger releases the roller 8, and then under the action of the deformation force of the spring 62, the fixing frame 7 returns to its original position along the slide rail 6. At the same time, the spring 62 can also play a buffering role for the fixing frame 7.

[0039] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them with similar methods, without departing from the spirit of the present invention.
