[0002] As a key electrical connection component, the conductive performance test of the connectors of the wiring harness is extremely important. At present, the commonly used detection method is to use a wiring harness tester to quickly test it. In order to adapt to connectors of different shapes and specifications, the tester is equipped with adapter plugs of various shapes. During the detection process, the operator must first select the adapter plug that matches the connector to be tested and connect it to the input port of the tester, and then plug the connectors into the adapter plug one by one to detect their conductive performance.

[0003] However, this method that relies on manual operation has some obvious shortcomings. First, the manual plugging and unplugging process is inefficient, especially the manual plugging and unplugging efficiency is low.

[0021] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0022] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0023] Reference Figures 1-3 The present embodiment provides a conductive performance detection device for a wiring harness connector, including a wiring harness detector 1, which is used to detect the wiring harness sequence, whether the wiring harness is conductive, and other functions of the wiring harness connector 3, and an adapter component 2 is arranged for automatically performing plug-in and unplug connection between the wiring harness connector 3 and the wiring harness detector 1. It includes a shell 21, and a conveyor belt 22 for transporting the wiring harness connector 3 is arranged in the shell 21. A camera 23 and an adapter plug 24 corresponding to the wiring harness connector 3 are also arranged in the shell 21. The adapter plug 24 is plugged into the input port 11 of the wiring harness detector 1 through an adapter line. The adapter plug 24 is driven to flip and retract through a power piece 25, and is used to adjust the front and back sides and plug into the wiring harness connector 3. At the same time, the power piece 25 also drives the conveyor belt 22 to transport step by step.

[0024] In this embodiment, the present invention is improved on the basis of the traditional wire harness tester 1, and a new arranging and switching component 2 is added to realize the automation and intelligence of the detection process. The device comprises a wire harness tester 1 and an arranging and switching component 2, wherein the wire harness tester 1 is responsible for detecting various conductive properties of the wire harness of the wire harness connector 3 and other functions; the arranging and switching component 2 realizes the automatic plug-in connection between the wire harness connector 3 and the wire harness tester 1 and the detection of the linear arrangement order inside the wire harness, and is specifically composed of a housing 21, a conveyor belt 22, a camera 23, a power part 25, etc., wherein the conveyor belt 22 is responsible for gradually conveying the wire harness connector 3 to a designated position for the convenience of subsequent detection operations; the camera 23 shoots the wire harness connector 3 to detect the wire core sequence and the front and back sides; the adapter plug 24 is connected to the input port 11 of the wire harness tester 1 through the adapter line; the power part 25 controls its flipping and extension, adjusts the front and back sides and accurately docks with the wire harness connector 3, and at the same time drives the conveyor belt 22 to transport in steps, coordinates the actions of various components, and ensures the automation and efficiency of the detection process.

[0025] The device realizes automatic identification and adjustment of the front and back sides of the wiring harness connector 3, avoids the errors and inefficiency problems that may be caused by manual operation, significantly improves the accuracy and reliability of detection, and through automatic plug-in connection, not only reduces labor costs, but also improves detection efficiency, and can quickly detect the conductive properties of the wiring harness connector 3, meeting the needs of large-scale and rapid detection on modern production lines. In addition, the device can effectively protect the wiring harness connector 3, avoid damage to the wiring harness connector 3 that may be caused by improper manual operation, thereby reducing production costs. The function of the camera 23 to shoot and detect the sequence of wire cores helps to discover possible wiring errors in the production process of the wiring harness connector 3, further improving the level of product quality control.

[0026] Among them, when designing a conductive performance detection device for a wiring harness connector, the electrical connection and unified control of electrical components such as the camera 23, the electric rotating rod 2583 and the electric telescopic cylinder 255 in the adapter component 2 with the wiring harness detector 1 are the key links to realize automated detection.

[0027] Specifically, the electrical connection method between the electrical components and the wiring harness detector 1: The electrical components such as the camera 23, the electric rotating rod 2583, and the electric telescopic cylinder 255 in the sorting and transfer component 2 can be electrically connected to the wiring harness detector 1 wirelessly or by wire. (1) Wired connection: Usually, methods such as ribbon cables and cables are used to connect these electrical components to the control board or interface of the wiring harness detector 1. This connection method is stable and reliable, and can ensure the high-speed and accurate transmission of data and control signals. (2) Wireless connection: Using wireless communication technologies such as Bluetooth and Wi-Fi to achieve wireless connection between the electrical components and the wiring harness detector 1. This method can reduce the bondage of cables and improve the flexibility and maintainability of the equipment. Communication protocol: In order to ensure smooth and accurate communication between each electrical component and the wiring harness detector 1, a unified communication protocol needs to be adopted. Common communication protocols include wired communication protocols such as UART, SPI, and I2C, as well as wireless communication protocols such as the HCI protocol of Bluetooth and the 802.11 protocol of Wi-Fi. These protocols specify the data transmission format, rate, verification method, etc., ensuring that different devices can correctly understand and process the information sent by each other.

[0028] The wiring harness detector 1, as the core control unit of the entire detection device, is responsible for the unified control of each electrical component in the sorting and transfer component 2. It is usually equipped with control chips such as microprocessors or single-chip microcomputers, and runs a preset control program to achieve precise coordination and operation of each component. During the detection process, the wiring harness detector 1 orderly commands the work of each electrical component according to the preset control logic. For example, when a new wiring harness connector 3 needs to be detected, the detector first controls the conveyor belt 22 to transport the connector to the specified position, then controls the camera 23 to take a picture of the connector to obtain its image information, and then adjusts the angle of the adapter plug 24 through the electric rotating rod 2583 according to the shooting result to ensure that it is directly opposite to the front of the wiring harness connector 3. Finally, it controls the electric telescopic cylinder 255 to drive the adapter plug 24 to be inserted into the wiring harness connector 3, and monitors parameters such as electrical conductivity during the insertion process. To ensure the accuracy and reliability of the control, each electrical component is usually equipped with corresponding sensors to feedback its own status information to the wiring harness detector 1. For example, the electric rotating rod 2583 and the electric telescopic cylinder 255 can be equipped with encoders or position sensors to report their rotation angles and telescopic positions to the wiring harness detector 1 in real time. The wiring harness detector 1 adjusts the control instructions in a timely manner according to these feedback information to ensure the smooth progress of the entire detection process.

[0029] Through the above methods, the electrical components in the sorting and transfer component 2 and the wiring harness detector 1 have achieved a close electrical connection and unified control operation, so as to be able to efficiently and accurately complete the electrical conductivity detection task of the wiring harness connector 3.

[0030] Refer toFigures 3-5 The housing 21 is provided with a through T-shaped groove 211. The wire harness connector 3 is horizontally inserted into one end of the T-shaped groove 211. The upper surface of the conveyor belt 22 is located in the T-shaped groove 211 and contacts the lower surface of the wire harness connector 3.

[0031] It should be noted that the wire harness connector 3 can be horizontally inserted from the open end of the T-shaped groove 211 and moved along the direction of the T-shaped groove 211 until it reaches the detection position. The upper surface of the conveyor belt 22 is located inside this T-shaped groove 211 and directly contacts the lower surface of the wire harness connector 3. When the conveyor belt 22 is started, it will drive the wire harness connector 3 to move step by step along the direction of the T-shaped groove 211, accurately transporting the wire harness connector 3 to the detection area.

[0032] The advantages of such a setting are as follows: The wire harness connector 3 can be easily inserted from one end of the T-shaped groove 211 without complex alignment or installation steps, simplifying the operation process and improving the detection efficiency. The design of the T-shaped groove 211 provides stable support and guidance for the wire harness connector 3, ensuring that the wire harness connector 3 will not shift or shake during transportation, thus guaranteeing the accuracy of detection. The combination of the conveyor belt 22 and the T-shaped groove 211 enables the wire harness connector 3 to automatically step to the detection position, realizing the automation of the detection process, reducing manual intervention, and reducing the errors and risks brought by manual operation. The through design of the T-shaped groove 211 makes the structure of the detection device more compact, rationally utilizes space, and is convenient for arrangement and use on the production line.

[0033] The conveyor belt 22 includes a belt body 221 and two sets of driven wheels 222 located at both ends of the belt body 221. An active wheel ring 223 is arranged below the belt body 221. Two symmetric auxiliary wheels 224 are arranged inside the belt body 221 to press the belt body 221 against the outer wall of the active wheel ring 223. A ratchet ring 225 is arranged inside the active wheel ring 223. The inner wall of the ratchet ring 225 is provided with threads and is screwed with a rod body 256. One end of the rod body 256 (which consists of a smooth rod, a screw rod, and a smooth rod in sequence) is fixed to a fixed plate 254, and the output shaft of the electric telescopic cylinder 255 is connected to the fixed plate 254.

[0034] The belt body 221 is the main part of the conveyor belt 22, which is used to carry the wiring harness connector 3. Its upper surface is in contact with the lower surface of the wiring harness connector 3, providing a platform for supporting and transporting the wiring harness connector 3. The driven wheels 222 are two sets of wheels located at both ends of the belt body 221, which mainly play the role of guiding and supporting the belt body 221, ensuring that the belt body 221 remains stable and flat during operation, and ensuring that the upper surface of the belt body 221 is in contact with the lower surface of the wiring harness connector 3, preventing the belt body 221 from shifting or loosening. The driving wheel ring 223 is set at the lower outer side of the belt body 221, and is the power source of the conveyor belt 22. The rotation of the driving wheel ring 223 will drive the belt body 221 to move, thereby realizing the step-by-step transportation of the wiring harness connector 3. The auxiliary wheels 224 are two wheels symmetrically arranged inside the belt body 221, and are used to press the belt body 221 against the outer wall of the driving wheel ring 223. Their function is to increase the friction between the belt body 221 and the driving wheel ring 223, ensuring that the driving wheel ring 223 can effectively drive the belt body 221 to move. At the same time, it also helps to maintain the tension of the belt body 221 and improve the stability of transportation.

[0035] The ratchet ring 225 is arranged inside the driving wheel ring 223, and its inner wall is provided with threads. The ratchet ring 225 cooperates with the rod body 256 to realize the control and adjustment of the rotation of the driving wheel ring 223. The rod body 256 is composed of three parts, namely, a polished rod, a screw rod, and a polished rod arranged in sequence. One end of the rod body 256 is fixed to the fixing plate 254. The rod body 256 is screwed to the ratchet ring 225 through threads. When the rod body 256 moves inside the ratchet ring 225, the ratchet ring 225 can be driven to rotate as needed, thereby controlling the rotation of the driving wheel ring 223. The specific diameter of the light rod part is smaller than that of the screw part, and it does not drive the ratchet ring 225 to rotate. It is mainly used to keep the ratchet ring 225 and the driving wheel ring 223 stationary at certain stages, so that the conveyor belt 22 is immobile, and a stable environment is provided for the plugging and separation of the wiring harness connector 3 and the adapter plug 24. The screw part drives the ratchet ring 225 to rotate, but due to the special design of the ratchet ring 225, its forward movement will cause the ratchet ring 225 to idle, and the driving wheel ring 223 will not rotate, thereby realizing the immobility of the conveyor belt 22, and the backward movement will cause the ratchet ring 225 to rotate, and the driving wheel ring 223 will rotate, thereby realizing the stepping movement of the conveyor belt 22. This design can accurately control the movement state of the conveyor belt 22 and meet the precise requirements for the position of the wiring harness connector 3 during the detection process. The electric telescopic cylinder 255 is used as a power source, and its output shaft is connected to the fixed plate 254. The telescopic action of the electric telescopic cylinder 255 will drive the fixed plate 254 and the rod body 256 connected thereto to move forward and backward.

[0036] Working principle and advantages: When it is necessary to detect the wire harness connector 3, the output shaft of the electric telescopic cylinder 255 extends or contracts, driving the fixed plate 254 and the rod body 256 to move within the driving wheel ring 223. According to the position and state of the rod body 256 within the ratchet ring 225, precise control of the rotation of the driving wheel ring 223 can be achieved: (1) The stage when the conveyor belt 22 is stationary: During the detection process, when it is necessary for the wire harness connector 3 to remain stationary for operations such as photographing and plugging, the smooth rod portion of the rod body 256 contacts the ratchet ring 225 without driving the ratchet ring 225 to rotate. The driving wheel ring 223 is stationary, and the conveyor belt 22 is not moving, ensuring the stable position of the wire harness connector 3 and improving the accuracy of detection. (2) The stage when the conveyor belt 22 makes a step: When a detection cycle is completed and it is necessary to transport the next wire harness connector 3 to the detection position, the electric telescopic cylinder 255 drives the rod body 256 to move, causing the screw portion to contact and drive the ratchet ring 225 to rotate. However, due to the special design of the ratchet ring 225, when the rod body 256 moves forward, the driving wheel does not rotate and the conveyor belt 22 does not move; when the rod body 256 moves backward, the driving wheel ring 223 rotates and the conveyor belt 22 moves to achieve precise step control. Subsequently, when the rod body 256 moves again to the point where the smooth rod portion contacts the ratchet ring 225, the conveyor belt 22 continues to remain stationary, preparing for the next detection cycle.

[0037] The advantage of this structural design of the conveyor belt 22 is that it can achieve precise step control and stable stillness of the conveyor belt 22, meeting the strict requirements for position and motion state during the detection process of the wire harness connector 3, improving the efficiency and accuracy of detection. At the same time, through the cooperation of the electric telescopic cylinder 255 and the rod body 256, automatic control of the driving wheel ring 223 and the conveyor belt 22 is achieved, reducing manual intervention and lowering the operation difficulty and error rate.

[0038] In order to adapt to different models of wire harness connectors 3, a variety of different models of adapter plugs 24 are designed. Each model of adapter plug 24 corresponds one-to-one with a specific wire harness connector 3, which means that different adapter plugs 24 will vary in shape, size, pin arrangement, etc. to precisely match the interface specifications of various wire harness connectors 3.

[0039] The adapter plug 24 is installed in the ring 251 of the power component 25. Two tightening bolts 252 are symmetrically arranged on the wall of the ring 251. The function of these two bolts is to squeeze the adapter plug 24, thereby firmly locking it within the ring 251 to ensure that the adapter plug 24 can stably dock and be plugged and unplugged with the wire harness connector 3 during the detection process.

[0040] Operation process of replacing the adapter plug 24: When it is necessary to detect a new wire harness connector 3 each time, first select a corresponding one from the alternative adapter plugs 24 according to the model of the wire harness connector 3. At the same time, ensure that the sorting adapter part 2 is in the initial position, that is, the electric telescopic cylinder 255 retracts to the shortest, and the ring 251 moves to the initial position of the guiding groove 258 of the semi-circular tube 257, so as to facilitate the replacement operation of the adapter plug 24. Manually loosen the two fastening bolts 252 symmetrically arranged on both sides of the ring 251, rotate the bolts counterclockwise to loosen them, so as to release the locking force on the old adapter plug 24. Take out the old adapter plug 24 from the ring 251, and then put the newly selected corresponding model adapter plug 24 into the ring 251. During the placement process, pay attention to the correct installation direction and position of the adapter plug 24 to ensure that it is at the center inside the ring 251. Tighten the two fastening bolts 252 again to squeeze and lock the adapter plug 24. This step requires tightening the bolts according to certain torque requirements to ensure that the adapter plug 24 is firmly fixed in the ring 251 and will not loosen or fall off during the subsequent detection process. After completing the above steps, the new adapter plug 24 is successfully installed in the sorting adapter part 2, preparing for the detection of the wire harness connector 3 next. Through the above steps, the adapter plug 24 can be replaced quickly and accurately to meet the detection requirements of different models of wire harness connectors 3, improving the versatility and detection efficiency of the detection equipment.

[0041] A bearing 253 is sleeved on the outer wall of the ring 251. A fixed plate 254 is arranged at the lower end of the bearing 253. An electric telescopic cylinder 255 is arranged in the housing 21, and the output shaft of the electric telescopic cylinder 255 is connected to the fixed plate 254.

[0042] The ring 251 is used to install the adapter plug 24. A bearing 253 is sleeved on its outer wall. The bearing 253 is matched with the ring 251 to rotate, so that the ring 251 can not only move back and forth telescopically driven by the electric telescopic cylinder 255, but also perform linear or flipping operations along with the semi-circular tube 257, enabling the ring 251 to be more smooth and stable during the movement process. An electric telescopic cylinder 255 is arranged inside the housing 21, and its output shaft is connected to the fixed plate 254. The electric telescopic cylinder 255 is a device that can convert electrical energy into mechanical energy, and drives the fixed plate 254 and the components connected thereto to perform corresponding movements through the telescopic action of the output shaft.

[0043] Refer to Figures 3-6, a semi-circular tube 257 is provided inside the housing 21. The semi-circular tube 257 is sleeved on the upper surface of the ring 251. A guiding groove 258 is provided on the inner wall of the semi-circular tube 257, and a convex block 259 is provided on the outer wall of the ring 251. The convex block 259 slides along the guiding groove 258 to control whether the adapter plug 24 flips. The guiding groove 258 is divided into a straight groove 2581 and an arc groove 2582. The arc groove 2582 spans the inner wall of the semi-circular tube 257 and its two ends are located on the same horizontal plane and are arranged in a staggered manner. The entrance of the arc groove 2582 is connected to the straight groove 2581, and an electric rotating rod 2583 is provided at the entrance. Both ends of the arc groove 2582 have a straight part.

[0044] Inside the housing 21, a semi-circular tube 257 is provided. The semi-circular tube 257 is sleeved on the upper surface of the ring 251. There is a certain gap between the inner wall of the semi-circular tube 257 and the outer wall of the ring 251 to allow the ring 251 to perform movements such as sliding and rotating within the semi-circular tube 257. A guiding groove 258 is provided on the inner wall of the semi-circular tube 257, and a convex block 259 is provided on the outer wall of the ring 251. The shape and size of the convex block 259 match the guiding groove 258 and can slide along the guiding groove 258. This design enables the ring 251 driven by the electric telescopic cylinder 255 to move linearly and also be restricted and guided by the guiding groove 258, thereby achieving precise control of the movement trajectory of the adapter plug 24.

[0045] The guiding groove 258 is divided into two types: a straight groove 2581 and an arc groove 2582. The straight groove 2581 is in a straight shape, and the width of the groove is slightly larger than the width of the convex block 259 to ensure that the convex block 259 can slide smoothly in the groove and at the same time provide sufficient support and guiding function. The straight groove 2581 usually runs through the semi-circular tube 257 and is used to guide the ring 251 and the convex block 259 thereon to move linearly. When the electric telescopic cylinder 255 drives the ring 251 to move forward, the convex block 259 first enters the straight groove 2581 and slides along the straight groove 2581, causing the ring 251 and the adapter plug 24 to move in a straight line direction, achieving alignment and insertion with the wire harness connector 3 without flipping.

[0046] The arc groove 2582 is arc-shaped with a central angle of 180 degrees to achieve a complete flip of the adapter plug 24. The entrance of the arc groove 2582 is set at any position in the first half of the straight groove 2581 and is connected to it. The end of the arc groove 2582 is also connected to a section of the straight groove 2581 for the smooth insertion of the flipped adapter plug 24. The main function of the arc groove 2582 is to guide the ring 251 and the convex block 259 thereon to perform an arc movement when the adapter plug 24 needs to flip, so that the adapter plug 24 can achieve a 180-degree flip to meet the reverse insertion requirement of the wire harness connector 3.

[0047] Electric rotating rods 2583 are provided at both the front and rear entrances of the arc-shaped groove 2582 to control the switching of the guiding groove 258. When the adapter plug 24 needs to be flipped, the electric rotating rod 2583 rotates to block the straight groove 2581 and open the arc-shaped groove 2582, enabling the bump 259 to smoothly enter the arc-shaped groove 2582, thereby realizing the flipping action of the adapter plug 24.

[0048] Through the telescopic action of the electric telescopic cylinder 255, the circular ring 251 is driven to slide along the guiding groove 258 of the semi-circular tube 257. The sliding trajectory of the bump 259 in the guiding groove 258 determines the movement mode of the adapter plug 24. The straight groove 2581 is used for straight plugging, and the arc-shaped groove 2582 is used for flipping plugging, achieving automatic adaptation and precise docking of different front and back side wire harness connectors 3. This structural design enables the detection device to automatically identify the front and back sides of the wire harness connector 3, and through the cooperation of the guiding groove 258 and the bump 259, automatically adjust the position and angle of the adapter plug 24 without manual intervention, improving the automation level and flexibility of the detection process. The precise cooperation of the guiding groove 258 and the bump 259 ensures the stability and accuracy of the adapter plug 24 during movement, avoiding poor plugging or detection errors caused by position deviation, and improving the reliability of the detection results. Through the ingenious design and cooperation of components such as the semi-circular tube 257, the guiding groove 258, the bump 259, and the electric rotating rod 2583, the detection device realizes the automatic identification of the front and back sides of the wire harness connector 3 and the automatic flipping and plugging of the adapter plug 24, improving the detection efficiency and accuracy, reducing the complexity and error rate of manual operation, and providing an efficient and reliable solution for the conductive performance detection of the wire harness connector 3.

[0049] Refer to Figures 1-6 , the operation process of the detection device: I. Preparation work Select and install the adapter plug 24: According to the type of the wire harness connector 3, select the corresponding adapter plug 24 and install it into the sorting and transferring component 2.

[0050] Initialize the electric telescopic cylinder 255: Retract the electric telescopic cylinder 255 to the shortest length and move the circular ring 251 to the initial position of the guiding groove 258 of the semi-circular tube 257.

[0051] Fix the adapter plug 24: Manually loosen the two tightening bolts 252 on both sides of the circular ring 251, replace the corresponding adapter plug 24 and tighten the bolts again to lock it, completing the replacement and installation of the adapter plug 24.

[0052] II. Detection process Insert the wire harness connector 3: Insert the wire harness connectors 3 one by one from the entrance at one end of the T-shaped groove 211. After the wire harness connector 3 enters the T-shaped groove 211, it is driven by the internal conveyor belt 22 for step-by-step movement.

[0053] Shooting and information processing: When the wire harness connector 3 is transported by the conveyor belt 22 to the position aligned with the camera 23, the camera 23 takes a picture of it to obtain the image information of the wire harness connector 3, and this information is sent to the wire harness detector 1. The wire harness detector 1 determines whether the core order of the wire harness connector 3 is correct, as well as information such as the front and back of the wire harness connector 3.

[0054] Controlling the movement of the adapter plug 24: The wire harness detector 1 controls whether the electric rotating rod 2583 rotates according to the front and back information of the wire harness connector 3, realizes the switching of the guiding groove 258, and further flips and switches the adapter plug 24.

[0055] Front-side insertion: When the wire harness connector 3 is on the front side, the electric rotating rod 2583 does not rotate, and the electric telescopic cylinder 255 drives the ring 251 to move forward through the fixed plate 254 and the bearing 253. During the forward movement of the ring 251, the convex block 259 on the ring 251 moves along the straight groove 2581 of the guiding groove 258, so that the adapter plug 24 is stably inserted into the wire harness connector 3.

[0056] Back-side insertion: When the wire harness connector 3 is on the back side, the electric rotating rod 2583 rotates, and the electric telescopic cylinder 255 drives the ring 251 to move forward through the fixed plate 254 and the bearing 253. During the forward movement of the ring 251, the straight groove 2581 in the blocking guiding groove 258 is blocked and the arc groove 2582 is opened. The convex block 259 on the ring 251 moves along the arc groove 2582, so that the ring 251 makes a 180-degree flip along the arc groove 2582 during the forward movement, realizing the flipping of the adapter plug 24, and then it is inserted into the wire harness connector 3.

[0057] Keeping the conveyor belt 22 stationary: During the forward movement of the adapter plug 24, the rod 256 (composed of three parts: a smooth rod, a screw rod, and a smooth rod) in front of the fixed plate 254 moves forward inside the inner wall of the ratchet ring 225. The smooth rod part does not drive the ratchet ring 225 to rotate, and the screw rod part drives the ratchet ring 225 to rotate, but due to the setting of the ratchet ring 225, it rotates idly, the driving wheel ring 223 does not rotate, and the conveyor belt 22 does not move. The conveyor belt 22 does not move throughout the process.

[0058] III. Reset after detection Retracting and resetting: After the insertion detection is completed, the electric telescopic cylinder 255 contracts, driving the ring 251 and the adapter plug 24 to retract and reset.

[0059] Transport belt 22 step-by-step transfer: At this time, the polished rod on the rod body 256 contacts the ratchet ring 225 until the adapter plug 24 is completely separated from the wire harness connector 3. Subsequently, the screw part on the rod body 256 contacts the ratchet ring 225 and drives the ratchet ring 225 to rotate. The ratchet ring 225 drives the driving wheel ring 223 to rotate, and the driving wheel ring 223 drives the transport belt 22 to rotate, realizing a step-by-step standard pitch transfer of the wire harness connector 3 on the transport belt 22.

[0060] Reset completed: Subsequently, another polished rod part contacts the ratchet ring 225, the transport belt 22 does not move, and the adapter plug 24 is completely reset along the arc-shaped groove 2582, preparing for the next detection.

[0061] Finally, it should be pointed out that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
