Description

Technical Field

[0001] This invention relates to the field of wire harness continuity testing, and more specifically to a rapid testing device for wire harness continuity testing. Background Technology

[0002] A wire harness is a circuit connection assembly formed by crimping contact terminals with wires and cables, and then insulating or molding them into a housing. It is the "neural network" for transmitting power and signals in various electrical systems, and its quality and reliability directly determine the operational safety and performance stability of the entire equipment.

[0003] In patent application CN218298315U, published on 2023-01-13 and entitled "A Novel Conductive Testing Platform for Automotive Wiring Harnesses," this application discloses a novel conductive testing platform for automotive wiring harnesses, relating to the field of conductive testing platform technology. It includes a support base, with a conductive testing platform body mounted on the top surface of the support base, and a guide frame mounted on the top surface of the conductive testing platform body. The use of a connecting mechanism in this invention allows for stable placement of the computer monitor, keyboard, and mouse. The guide plate can slide along the inner side of the guide frame to change the computer's position, facilitating use by staff during testing. The monitor angle can be adjusted, allowing for data observation from different testing positions. A rotating mechanism allows the seat to rotate outwards from under the conductive testing platform for staff to rest. When the seat is not in use, a torsion spring allows the rotating sleeve to rotate, resetting the seat and saving space by not occupying the side of the conductive testing platform, thus providing a convenient resting place for staff.

[0004] In existing wire harness continuity testing devices, including those mentioned above, the terminals of the wire harness to be tested must be plugged into the testing terminals of the device during use. To prevent accidental detachment during use, industrial wire harness terminals generally integrate a flexible snap-fit ​​structure to achieve mechanical locking with the mating terminals. However, this snap-fit ​​design brings significant drawbacks in batch testing scenarios: on the one hand, the locking and unlocking operations of the snap-fit ​​increase the number of insertion and removal steps, significantly reducing testing efficiency; on the other hand, if uneven force or angle deviation is applied during manual insertion and removal, it is very easy to cause the snap-fit ​​to deform or break, or even cause the terminal pins to bend and be damaged, which not only increases the scrap rate of wire harness production, but may also leave hidden quality hazards of poor contact.

[0005] Therefore, it is necessary to invent a rapid detection device for wire harness continuity testing to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a rapid testing device for wire harness continuity testing. Through a purely mechanical linkage structure, it realizes automatic pre-limiting of wire harness terminals, pre-opening of latches, and step-by-step delayed insertion and removal of terminals by first releasing the latches and then pulling out the terminals. This solves the problems in the prior art where latch-type wire harness terminals are prone to latch breakage due to gravity collisions, hard friction, and improper manual operation during the insertion and removal process, and the insertion and removal operation is cumbersome and the testing efficiency is low.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rapid testing device for wire harness continuity testing, comprising a testing cabinet, a testing panel mounted on one side of the upper part of the testing cabinet, power-conducting interfaces symmetrically mounted on the surface of the testing panel, and all power-conducting interfaces being electrically connected to internal components of the testing cabinet, a display screen mounted on the bottom of the testing cabinet, a fixing frame mounted above each of the two sets of power-conducting interfaces, a power-conducting pin mounted within each of the two sets of fixing frames, and the power-conducting pin being plugged into the power-conducting interface, a connecting frame disposed at the lower part of the fixing frame, limit holes being formed at the four corners of the upper part of the connecting frame, a compression frame disposed at the upper part of the fixing frame, and limit rods mounted at the four corners of the lower part of the compression frame, the limit rods being slidably connected to the corresponding limit holes for limiting.

[0008] As a preferred embodiment of the present invention, a connecting terminal is electrically connected above the power-on pin, and the connecting terminal is located within a fixed frame, with slots symmetrically opened on both sides of the connecting terminal.

[0009] As a preferred embodiment of the present invention, through slots are provided on both sides of the connecting frame, and connecting plates are slidably connected in both sets of through slots. Inserts are symmetrically installed on one side of the connecting plates, and the inserts on the two sets of connecting plates are arranged opposite to each other.

[0010] As a preferred embodiment of the present invention, each of the two sets of connecting plates is symmetrically equipped with a compression block on the side away from the insert, and the compression block is in contact with the inner wall of the corresponding fixing frame.

[0011] As a preferred embodiment of the present invention, guide rods are installed on the inner walls of both sets of through grooves, and the two sets of guide rods are connected through the corresponding connecting plates. A spring is sleeved on each set of guide rods, and the two ends of the spring are respectively attached to the connecting plate and the inner wall of the through groove.

[0012] As a preferred embodiment of the present invention, a positioning hole is symmetrically provided on the inner wall of the fixed frame, and the positioning hole and the corresponding extrusion block are at the same vertical and horizontal position.

[0013] As a preferred embodiment of the present invention, handles are installed above both sets of extrusion frames, and through holes are symmetrically opened on both sides of the extrusion frames. A connecting rod is connected through the through hole, and an extrusion plate is installed at one end of the connecting rod, and the extrusion plate is located on the inner wall of the extrusion frame.

[0014] As a preferred embodiment of the present invention, a second extrusion block is installed at the other end of the connecting rod, and the second extrusion block is slidably connected to the through hole.

[0015] As a preferred embodiment of the present invention, a second spring is sleeved on the connecting rod, and the two ends of the second spring are respectively attached to the inner wall of the through hole and the second extrusion block.

[0016] As a preferred embodiment of the present invention, a second positioning hole is symmetrically provided on the upper part of the inner wall of the fixed frame, and a third positioning hole is symmetrically provided on the lower part of the inner wall of the fixed frame. The second positioning hole is engaged with the second pressing block, and the third positioning hole is at the same vertical and horizontal position as the second positioning hole.

[0017] Compared with the prior art, the technical effects and advantages provided by the present invention in the above technical solution are as follows: During the placement phase, the extended insert forms a stable pre-limiting position to support the bottom of the terminal, preventing the terminal from falling prematurely due to gravity and colliding with the connecting terminal and causing damage. During the insertion phase, the extrusion plate pre-opens the elastic clips on both sides of the terminal simultaneously, completely eliminating hard friction and scratch damage between the clips and the connecting terminal slot during insertion. During the removal phase, the extrusion plate first completely disengages the clips from the slot, and then the insert is inserted into the connection gap to assist in separation, allowing the two to perform step-by-step delayed actions. This fundamentally solves the problems of terminal deformation, clip breakage, and pin bending caused by uneven force and angle deviation during traditional manual insertion and removal, significantly reducing the scrap rate in the wire harness inspection process. During operation, the entire process of wire harness pre-positioning, automatic insertion, locking detection, and rapid unlocking can be completed by simply pulling the handle with one hand, without the need for additional tools or complex operations, thus increasing testing efficiency. Furthermore, the modular design integrating the fixed frame and energized pins allows for rapid replacement of test fixtures for different wire harness specifications within seconds, eliminating the need for rewiring or equipment debugging, perfectly adapting to the current flexible production model of multiple varieties and small batches. In addition, the precise coaxial positioning and dual locking structure of the mechanical linkage ensure consistent and reliable contact depth between the wire harness terminals and the connecting terminals, effectively avoiding false detections and missed detections caused by poor connections or poor contact, thus improving the consistency and reliability of test results.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] This invention provides, for example Figures 1-11The diagram shows a rapid testing device for wire harness continuity testing, comprising a testing cabinet 101, a testing panel 102 mounted on one side of the top of the testing cabinet 101, power interfaces 103 symmetrically mounted on the surface of the testing panel 102, and each power interface 103 electrically connected to the internal components of the testing cabinet 101, a display screen 104 mounted on the bottom of the testing cabinet 101, a fixing frame 201 mounted above each of the two sets of power interfaces 103, a power pin 202 mounted inside each of the two sets of fixing frames 201, and the power pin 202 plugged into the power interface 103, a connecting frame 301 disposed at the lower inside of the fixing frame 201, a limit hole 309 provided at each of the four upper corners of the connecting frame 301, a compression frame 401 disposed at the upper inside of the fixing frame 201, a limit rod 403 mounted at each of the four lower corners of the compression frame 401, and the limit rod 403 slidingly connected to the corresponding limit hole 309.

[0023] By integrating the fixing frame 201 with the power-on pin 202 and using a modular connection method where the power-on pin 202 is plugged into the power-on interface 103 on the detection panel 102, the replacement of test fixtures for wire harnesses of different specifications is realized. The limiting sliding structure of the limiting rod 403 and the limiting hole 309 ensures that the extrusion frame 401 and the connecting frame 301 maintain precise coaxiality during up and down movement, avoiding damage to the wire harness terminals or poor contact due to misalignment, thus improving the overall operational stability and testing reliability of the device. In addition, the terminals inside the extrusion frame 401 are used to hold and place the wire harness.

[0024] Furthermore, in the above structure, a connecting terminal 203 is electrically connected above the power-on pin 202, and the connecting terminal 203 is located inside the fixed frame 201. Slots 204 are symmetrically opened on both sides of the connecting terminal 203.

[0025] The connecting terminal 203 can be engaged with the latches on both sides of the wire harness terminal, and the slot 204 engages with the latches of the wire harness terminal to ensure the stability of the overall connection, thereby ensuring the normal operation of the test.

[0026] Furthermore, in the above structure, through slots 302 are provided on both sides of the connecting frame 301, and connecting plates 303 are slidably connected in both sets of through slots 302. Inserts 304 are symmetrically installed on one side of the connecting plate 303, and the inserts 304 on the two sets of connecting plates 303 are arranged opposite to each other, and the inserts 304 are located in the connecting frame 301.

[0027] The opposing inserts 304 slide synchronously within the connecting frame 301 via the connecting plate 303, allowing the inserts 304 to be inserted into the connection gap between the wire harness terminal and the connecting terminal 203. The through slot 302 provides a stable sliding track for the connecting plate 303, ensuring the linearity and consistency of the movement of the inserts 304.

[0028] Furthermore, in the above structure, each of the two sets of connecting plates 303 is symmetrically equipped with a compression block 305 on the side away from the insert 304, and the compression block 305 is in contact with the inner wall of the corresponding fixing frame 201.

[0029] By fitting the extrusion block 305 to the inner wall of the fixing frame 201, the downward linear movement of the extrusion frame 401 is converted into the horizontal movement of the connecting plate 303 towards the center. The operator only needs to press down on the extrusion frame 401 to move the extrusion block 305 into the positioning hole 308, which will simultaneously drive the two side inserts 304 to retract and completely retract from the connecting frame 301, so that the wire harness terminals can be inserted into the connecting terminal 203. When the inserts 304 are extended, they will limit the bottom of the wire harness terminals placed in the extrusion frame 401, which can prevent the wire harness terminals from falling down along the connecting frame 301.

[0030] Furthermore, in the above structure, guide rods 306 are installed on the inner walls of both sets of through grooves 302, and the two sets of guide rods 306 are connected through to the corresponding connecting plates 303. Springs 307 are sleeved on both sets of guide rods 306, and the two ends of the springs 307 are respectively attached to the connecting plate 303 and the inner wall of the through groove 302.

[0031] The guide rod 306 further enhances the stability of the sliding of the connecting plate 303, preventing the connecting plate 303 from deflecting or jamming during movement, and ensuring the synchronization and reliability of the insert 304. Spring 307 provides power to the connecting plate 303. When the detection moves downward, the pressing block 305 coincides with the positioning hole 308, and the pressing block 305 loses the pressing force of the inner wall of the fixing frame 201. Spring 307 can then push the connecting plate 303 to automatically reset to both sides, and the insert 304 moves synchronously to achieve the limiting of contact with the wire harness terminal. As the pressing frame 401 continues to move, the position of the connecting frame 301 is limited. However, due to the sliding of the limiting hole 309 and the release of the limiting at the bottom of the wire harness terminal, the pressing frame 401 can continue to move downward to complete the insertion of the wire harness terminal and the connecting terminal 203.

[0032] Furthermore, in the above structure, positioning holes 308 are symmetrically provided on the inner wall of the fixed frame 201, and the positioning holes 308 and the corresponding pressing blocks 305 are in the same vertical and horizontal position.

[0033] The positioning hole 308 allows the extrusion block 305 to have space for lateral movement during its up-and-down motion, ensuring that the insert 304 can move laterally.

[0034] Furthermore, in the above structure, handles 402 are installed above both sets of extrusion frames 401, and through holes 404 are symmetrically opened on both sides of the extrusion frame 401. A connecting rod 405 is connected through the through hole 404, and an extrusion plate 406 is installed at one end of the connecting rod 405, and the extrusion plate 406 is located on the inner wall of the extrusion frame 401.

[0035] The handle 402 allows the extrusion frame 401 to move downwards easily, while the connecting rod 405 allows the extrusion plate 406 to move within the connecting frame 301 or be hidden on the inner wall of the extrusion frame 401.

[0036] Furthermore, in the above structure, a compression block 407 is installed at the other end of the connecting rod 405, and the compression block 407 is slidably connected to the through hole 404.

[0037] By limiting and sliding the extrusion block 407 with the through hole 404, the extrusion block 407 can be effectively limited.

[0038] Furthermore, in the above structure, a second spring 408 is sleeved on the connecting rod 405, and the two ends of the second spring 408 are respectively attached to the inner wall of the through hole 404 and the second extrusion block 407.

[0039] Spring 2 408 can provide a restoring force to the pressing block 2 407, so that when it slides to the position where the positioning hole 2 409 and the positioning hole 3 410 coincide, the pressing block 2 407 can be engaged with them. Conversely, it is squeezed by the inner wall of the fixed frame 201, causing the pressing block 2 407 to move.

[0040] Furthermore, in the above structure, positioning holes 2 409 are symmetrically provided on the upper part of the inner wall of the fixed frame 201, and positioning holes 3 410 are symmetrically provided on the lower part of the inner wall of the fixed frame 201. Positioning holes 2 409 are engaged with pressing blocks 2 407, and positioning holes 3 410 and positioning holes 2 409 are in the same vertical and horizontal position.

[0041] By setting positioning hole 2 409 and positioning hole 3 410, sufficient space is reserved for the movement of extrusion block 2 407, so that extrusion plate 406 can move within extrusion frame 401, thereby extruding the buckles on both sides of the wire harness terminal, so that the buckles can disengage from the buckle slot 204, ensuring that the wire harness terminal can be smoothly disengaged from the connecting terminal 203, and vice versa, ensuring that the two can be smoothly engaged, thereby avoiding damage to the terminal itself during the insertion process.

[0042] like Figures 1-11As shown, the device is initially in the waiting position. At this time, the extrusion frame 401 is located at the top inside the fixed frame 201. The second extrusion block 407, under the elastic force of the second spring 408, is inserted into the positioning hole 409 on the upper part of the inner wall of the fixed frame 201, thus achieving the pre-positioning of the extrusion frame 401. At the same time, the first extrusion block 305 is tightly fitted to the inner wall of the fixed frame 201, overcoming the elastic force of the first spring 307 and pushing the connecting plate 303 to move towards the center, so that the two sets of opposing inserts 304 extend into the interior of the connecting frame 301, forming a horizontal limiting surface. The extrusion plate 406, under the action of the second spring 408, retracts to the inner wall of the extrusion frame 401, forming an open placement space inside the extrusion frame 401.

[0043] The operator places the terminal of the wire harness to be tested into the crimping frame 401 from above. At this time, the protruding insert 304 precisely supports the bottom of the wire harness terminal, forming a reliable pre-limiting position, effectively preventing the wire harness terminal from falling down along the connecting frame 301 during placement. This pre-limiting structure requires no manual adjustment; the wire harness terminal is automatically positioned after placement, greatly improving clamping efficiency.

[0044] The operator holds the handle 402 and presses the compression frame 401 downwards evenly. When the compression frame 401 begins to move downwards, the compression block 407 first comes out of the positioning hole 409 and is squeezed by the inclined surface of the inner wall of the fixed frame 201. It overcomes the elastic force of the spring 408 and moves towards the middle. Through the connecting rod 405, it pushes the compression plates 406 on both sides to extend towards the middle simultaneously, pre-compressing the elastic buckles on both sides of the wire harness terminal, causing the buckles to retract towards the terminal, preparing for subsequent insertion and avoiding damage caused by hard friction between the buckles and the connecting terminal 203 during the insertion process. As the compression frame 401 continues to move downwards, it pushes the connecting frame 301 below to move downwards through the wire harness terminal that is snapped inwards. When the connecting frame 301 moves to the testing station, the first pressing block 305 is aligned with the first positioning hole 308 on the inner wall of the fixed frame 201. At this time, the first pressing block 305 loses the pressing force of the inner wall of the fixed frame 201, and the first spring 307 quickly pushes the connecting plate 303 to reset to both sides, causing the insert 304 to retract synchronously into the through groove 302, completely releasing the limit on the bottom of the wire harness terminal. Due to the lower limit contact, the limit rod 403 slides to the bottom in the limit hole 309 of the connecting frame 301, allowing the pressing frame 401 to move a distance, thereby realizing the insertion of the wire harness terminal into the connecting terminal 203. At the same time, the buckles on both sides of the terminal are inserted into the slot 204, and as the pressing frame 401 is inserted and pushed forward, the second pressing block 407 coincides with the third positioning hole 410, thereby making the buckles on both sides of the terminal engage with the slot 204.

[0045] After the device is locked, the detection circuit inside the detection cabinet 101 sends detection electrical signals sequentially to each core wire of the wire harness under test through the power interface 103, power pin 202, and connection terminal 203 on the detection panel 102, and receives return signals. The detection cabinet 101 automatically analyzes parameters such as signal continuity and resistance to determine whether the wire harness has faults such as open circuit, short circuit, incorrect connection, or loose connection, and displays the detection results, fault location, and fault type in real time on the display screen 104 at the bottom for the operator to view.

[0046] After the inspection is completed, the operator holds handle 402 and pulls the compression frame 401 upward. As the compression frame 401 begins to move upward, the compression block 407 first disengages from the positioning hole 410 and is then squeezed by the inclined surface of the inner wall of the fixing frame 201, pushing the compression plate 406 to extend towards the center and squeezing the elastic clips on both sides of the wire harness terminal, causing them to automatically disengage from the slots 204 of the connecting terminal 203. As the compression frame 401 continues to move upward, the clips completely disengage from the slots 204. Furthermore, due to the delayed pulling between the compression frame 401 and the connecting frame 301, as the compression frame 401 continues to move upward... The connecting frame 301 moves upward, and the pressing block 305 comes out of the positioning hole 308. It is pressed again by the inner wall of the fixing frame 201, pushing the connecting plate 303 to move towards the middle. This causes the insert 304 to extend back into the connecting frame 301, so that it can be inserted into the gap between the wire harness terminal and the connecting terminal 203. This prevents the wire harness terminal from accidentally falling off during the unlocking process and ensures that the wire harness terminal can be smoothly pulled out from the connecting terminal 203. In addition, the delayed pulling between the pressing frame 401 and the connecting frame 301 can ensure that the buckle starts to pull the wire harness terminal upward only after the unlocking is completed, avoiding damage to the wire harness terminal.

[0047] When the extrusion frame 401 returns to the uppermost waiting position, the second extrusion block 407, under the elastic force of the second spring 408, re-engages into the second positioning hole 409, and the extrusion plate 406 simultaneously retracts to the inner wall of the extrusion frame 401, restoring the device to its initial waiting state. The operator can then easily remove the tested wire harness and prepare for the next inspection.

[0048] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
