Description

Technical Field

[0001] This utility model relates to the field of wire harness insertion and removal technology, and specifically to a support device for testing the insertion and removal life of wire harnesses. Background Technology

[0002] As a core connection component in electronic equipment, automotive, aerospace and other fields, the reliability of wire harnesses during insertion and removal directly determines the operational stability and service life of the entire device. In product development, mass production sampling inspection and quality traceability processes, wire harness insertion and removal life testing is a crucial step in evaluating its mechanical performance and connection reliability. This requires simulating repeated insertion and removal conditions in real-world usage scenarios to test key indicators such as the contact stability between the plug and socket, structural wear resistance, and fatigue life of elastic components.

[0003] Existing devices often use single rigid connectors with no effective elastic locking components. After insertion, the wire harness connectors are prone to loosening or shifting due to vibration during insertion and removal, leading to poor contact during testing. This not only affects the accuracy of electrical performance test data but may also cause interface wear due to connector movement, failing to accurately reflect the actual insertion and removal life of the wire harness. Furthermore, some devices do not perform graded, orderly, and fixed fixing of the test wire harnesses, which can easily lead to tangling and mutual interference when multiple wire harnesses are tested simultaneously, further exacerbating the instability of insertion and removal actions. To address these issues, a wire harness insertion and removal life testing support device is proposed. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a support device for testing the insertion and removal life of wire harnesses.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wire harness insertion and removal life test support device includes a base, a first profile frame fixedly connected to one side of the upper surface of the base, a second profile frame fixedly connected to the other side of the upper surface of the base, a controller fixedly connected to the top of the first profile frame, a self-insertion and removal detection locking mechanism provided on one side of the controller, a fixing box fixedly connected to the middle of the upper surface of the base, and a self-insertion and removal wire harness fixing mechanism provided on the front of the self-insertion and removal detection locking mechanism. The self-insertion detection and locking mechanism includes a panel, on the front of which are fixedly connected a plurality of detection ports, and on both sides of each detection port are fixedly connected a first elastic retaining plate, and on the top of the first elastic retaining plate are fixedly connected a first retaining ring.

[0006] The self-plugging wire harness fixing mechanism includes a connecting plate. A plurality of wire harness guide grooves are fixedly connected to the middle of the upper surface of the connecting plate. A plurality of wire harness fixing grooves are fixedly connected to the front of the connecting plate. A second spring retaining plate is fixedly connected to both sides of the wire harness fixing groove. A second retaining ring adapted to the first retaining ring is fixedly connected to the top of the second spring retaining plate. A plurality of limiting sleeves are fixedly connected to both sides of the connecting plate.

[0007] The beneficial effects of this utility model are as follows: the first elastic plate and the first retaining ring of the self-insertion and extraction detection locking mechanism, and the second spring plate and the second retaining ring of the self-insertion and extraction wire harness fixing mechanism are mutually adapted to each other. During insertion and extraction, the connection position of the wire harness and the detection socket can be firmly locked, avoiding loosening or displacement during the insertion and extraction process. At the same time, the wire harness guide groove can guide and straighten the wire harness segment that is not inserted into the detection socket. The wire harness fixing groove can fix the wire harness connector, prevent the wire harness from tangling or shifting, and greatly reduce the test error caused by the wire harness position deviation. The design of multiple detection sockets and corresponding wire harness fixing structures can carry out insertion and extraction life tests of multiple sets of wire harnesses at the same time, improving test efficiency. The elasticity of the elastic plate can not only ensure the locking effect, but also provide a buffer during insertion and extraction, avoiding damage to the interface and wire harness caused by rigid contact, and extending the service life of the testing device itself.

[0008] Furthermore, a motor is fixedly connected to one side of the inner wall of the fixed box, and a lead screw is driven to the output end of the motor. A lead screw protective sleeve is fitted on the outer surface of the lead screw.

[0009] The beneficial effects of the above solution are: the transmission combination of motor and lead screw replaces manual insertion and removal operation, which can realize the automated control of insertion and removal action. This not only reduces the intensity of manual labor, but also ensures the consistency of speed and force of each insertion and removal through the precise control of the motor, reducing human operation error.

[0010] Furthermore, a connecting rod is sleeved on the outer surface of the lead screw, and a heat dissipation vent and a baffle are fixedly connected to the upper surface of the fixing box from left to right. The baffle is adapted to the connecting rod, and the connecting rod is connected to the self-plugging wire harness fixing mechanism.

[0011] The beneficial effects of the above solution are as follows: the connecting rod, as the connecting bridge between the lead screw and the actuator, realizes the precise conversion of linear motion through threaded transmission, ensuring the stroke accuracy of the insertion and removal action, and providing a guarantee for the accuracy of test data. The setting of the heat dissipation port solves the heat dissipation problem in the enclosed space of the fixed box, avoiding the performance degradation or damage of the motor due to overheating during long-term operation. The baffle not only realizes the auxiliary limit of the movement trajectory of the connecting rod, improving the stability of the insertion and removal action, but also prevents external foreign objects from entering the fixed box.

[0012] Furthermore, a number of limiting rods connected to the second profile frame are fixedly connected to the top of one side of the first profile frame, and the limiting rods are adapted to the limiting sleeves.

[0013] The beneficial effects of the above solution are: the limiting rod connects the double profile frame into an integral frame, which effectively improves the deformation resistance of the support structure, can resist the vibration and impact force generated by the operation of the drive mechanism during the test, reduces the impact of structural shaking on the test accuracy, and at the same time serves as the limiting mechanism of the limiting sleeve.

[0014] Furthermore, a control panel is fixedly connected to the center of the front of the first profile frame, and several wire harness guide channels adapted to the self-plugging wire harness fixing mechanism are fixedly connected to the center of the inner wall of the second profile frame.

[0015] The beneficial effects of the above solution are: the control panel allows operators to directly set parameters and control the operation on the front of the device; the wire harness guide channel and wire harness guide groove form a multi-level guide system, which effectively constrains the wire harness outside the test area, avoiding entanglement, offset or stress during the wire harness introduction process, and further improving the stability and data accuracy of the insertion and removal test.

[0023] Example 1 Figure 1 This utility model provides an overall structural diagram of a wire harness insertion and removal life testing support device. Figure 2 The enlarged structural diagram of the main body of this utility model shows that the device includes: a base 1, a first profile frame 2 fixedly connected to one side of the upper surface of the base 1, a second profile frame 3 fixedly connected to the other side of the upper surface of the base 1, a controller 4 fixedly connected to the top of the first profile frame 2, a self-insertion and removal detection locking mechanism 5 provided on one side of the controller 4, a fixing box 6 fixedly connected to the middle of the upper surface of the base 1, and a self-insertion and removal wire harness fixing mechanism 12 provided on the front of the self-insertion and removal detection locking mechanism 5. Figure 5 This is a structural diagram of the self-insertion and extraction detection and locking mechanism of this utility model, as shown below. Figure 5 As shown, the self-insertion detection and locking mechanism 5 includes a panel 501. Several detection ports 502 are fixedly connected to the front of the panel 501. First elastic locking plates 503 are fixedly connected to both sides of the detection ports 502. A first retaining ring 504 is fixedly connected to the top of the first elastic locking plates 503.

[0024] Figure 6 This is a structural diagram of the self-inserting and unplugging wire harness fixing mechanism of this utility model, as shown below. Figure 6 As shown, the self-inserting wire harness fixing mechanism 12 includes a connecting plate 1201. A plurality of wire harness guide grooves 1202 are fixedly connected to the middle of the upper surface of the connecting plate 1201. A plurality of wire harness fixing grooves 1203 are fixedly connected to the front of the connecting plate 1201. A second spring retaining plate 1204 is fixedly connected to both sides of the wire harness fixing groove 1203. A second retaining ring 1205 adapted to the first retaining ring 504 is fixedly connected to the top of the second spring retaining plate 1204. A plurality of limiting sleeves 1206 are fixedly connected to both sides of the connecting plate 1201.

[0025] The base 1 serves as the supporting foundation for the entire device. A symmetrical support structure is formed by the first profile frame 2 and the second profile frame 3 fixed to both sides of its upper surface, providing a mounting carrier for other components. The controller 4 fixed to the top of the first profile frame 2 serves as the mounting base for the device's control core. A self-insertion / extraction detection and locking mechanism 5 on one side provides an installation position for the wire harness insertion / extraction docking end. The panel 501 in this mechanism fixes several detection ports 502 for mating with the plugs of the wire harness to be tested. The fixing box 6 in the middle of the base 1 provides a closed and stable enclosure for the subsequent installation of the drive mechanism. In the space, when preparing for testing, the plug of the wire harness to be tested can be initially aligned with the test socket 502. The first elastic clamping plates 503 on both sides of the test socket 502 can generate clamping force when the plug is inserted due to their own elastic deformation ability. The first retaining ring 504 at the top provides a structural basis for subsequent locking and positioning. The self-inserting wire harness fixing mechanism 12 fixed at the top of the connecting rod 9 serves as the mounting carrier for the wire harness to be tested. The connecting plate 1201 provides a mounting base for each component. Before testing, the wire harness to be tested is placed in the wire harness guide groove 1202 on the upper surface of the connecting plate 1201. The wire guide groove 1202 guides and constrains the wire portion, preventing tangling or misalignment during insertion and removal. The plug portion of the wire harness is fixed in the wire harness fixing groove 1203 on the front of the connecting plate 1201, achieving a stable connection between the plug and the mechanism. When the connecting rod 9 drives the connecting plate 1201 to move linearly, the connecting plate 1201 drives the fixed wire harness plug to engage with the detection socket 502, completing the life test. The second spring clamps 1204 on both sides of the wire harness fixing groove 1203, relying on their own spring elasticity, clamp the wire harness plug after it is placed in the fixing groove. The tension securely clamps the plug in the fixing slot. When the wire harness plug mates with the detection socket 502, the second retaining ring 1205 on the top of the second spring retaining plate 1204 and the first retaining ring 504 on the top of the first elastic retaining plate 503 engage with each other, achieving locking and positioning after the plug mates with the detection socket 502, ensuring the stability of the mating point during insertion and removal. Several limiting sleeves 1206 on both sides of the connecting plate 1201 can cooperate with other limiting structures of the device to further restrict the movement trajectory of the connecting plate 1201 when it moves linearly, preventing the connecting plate 1201 from shifting laterally.

[0026] Example 2 like Figure 3 and Figure 4 As shown, a motor 7 is fixedly connected to one side of the inner wall of the fixed box 6, and a lead screw 8 is driven to the output end of the motor 7. A lead screw protective sleeve is fitted on the outer surface of the lead screw 8.

[0027] The motor 7, which is fixed to one side of the inner wall of the fixed box 6, serves as the power source for the insertion and removal action. The output end of the motor 7 is connected to the lead screw 8. When the controller 4 issues the insertion and removal test command, the motor 7 receives the signal and drives the lead screw 8 to perform forward and reverse rotation. The lead screw protective sleeve on the outer surface of the lead screw 8 can isolate external dust and impurities from entering the lead screw transmission pair during the rotation of the lead screw 8, thus preventing foreign objects from affecting the transmission accuracy.

[0028] A connecting rod 9 is fitted on the outer surface of the lead screw 8. A heat dissipation vent 10 and a baffle 11 are fixedly connected from left to right on the upper surface of the fixing box 6. The baffle 11 is adapted to the connecting rod 9. The connecting rod 9 is connected to the self-plugging wire harness fixing mechanism 12.

[0029] The connecting rod 9, sleeved on the outer surface of the lead screw 8, forms a threaded transmission engagement with the lead screw 8. When the lead screw 8 rotates forward and backward under the drive of the motor 7, the connecting rod 9 converts the rotational motion of the lead screw 8 into its own linear reciprocating motion along the axis of the lead screw 8, thereby driving the top connected component to perform insertion and removal actions. The heat dissipation vent 10 on the upper surface of the fixed box 6 is connected to the internal space of the fixed box 6. The heat generated during the operation of the motor 7 can be quickly dissipated to the outside through the heat dissipation vent 10, preventing the temperature inside the fixed box 6 from being too high and affecting the performance of the motor 7 and transmission components. The baffle 11 on the upper surface of the fixed box 6 is adapted to the connecting rod 9. When the connecting rod 9 moves linearly, the baffle 11 can assist in limiting the movement trajectory of the connecting rod 9, while preventing external foreign objects from entering the interior from the opening on the upper surface of the fixed box 6.

[0030] Several limiting rods 13, which are connected to the second profile frame 3, are fixedly connected to the top of one side of the first profile frame 2. The limiting rods 13 are adapted to the limiting sleeves 1206.

[0031] Several limiting rods 13 fixed to the top of one side of the first profile frame 2 are fixedly connected to the second profile frame 3, so that the originally independent first profile frame 2 and second profile frame 3 form an integral frame structure through the limiting rods 13. During the operation of the device, the limiting rods 13 can transmit the force between the two profile frames, avoid the tilting or shaking of a single profile frame due to uneven force, and limit the position of the self-inserting wire harness fixing mechanism 12 to prevent displacement.

[0032] A control panel 14 is fixedly connected to the center of the front of the first profile frame 2, and several wire harness guide channels 15 adapted to the self-plugging wire harness fixing mechanism 12 are fixedly connected to the center of the inner wall of the second profile frame 3.

[0033] The control panel 14 in the center of the front of the first profile frame 2 is electrically connected to the controller 4. The operator can input test parameters through the control panel 14 and issue control commands such as start and stop. The control panel 14 can also display test progress, fault information and other data. Several wire harness guide channels 15 in the middle of the inner wall of the second profile frame 3 are adapted to the self-inserting wire harness fixing mechanism 12. After the test wire harness is introduced from one side of the device, it passes through the wire harness guide channel 15 and then enters the wire harness guide groove 1202. The wire harness guide channel 15 guides and constrains the wire harness before it enters the test area.

[0034] Working principle: One end of the wire harness to be tested is passed through the wire harness guide channel 15 on the inner wall of the second profile frame 3. After being guided and constrained, the wire portion of the wire harness is embedded into the wire harness guide groove 1202 of the connecting plate 1201 in the self-inserting wire harness fixing mechanism 12. Then, the wire harness plug is aligned and placed into the wire harness fixing groove 1203 on the front of the connecting plate 1201. At this time, the second spring clips 1204 on both sides of the wire harness fixing groove 1203 generate clamping force due to elastic deformation, which initially fixes the plug. At the same time, the limiting sleeves 1206 on both sides of the connecting plate 1201 are correspondingly matched with the limiting rods 13 of the first profile frame 2, completing the pre-positioning of the actuator.

[0035] The controller 4 sends a start command through the control panel 14, which drives the motor 7 inside the fixed box 6 to start. The output end of the motor 7 drives the lead screw 8 to rotate in the forward direction. The lead screw 8 drives the connecting rod 9 sleeved on the outer surface to move along the axis of the lead screw 8 towards the self-insertion detection and locking mechanism 5 through thread transmission. The connecting plate 1201 simultaneously drives the wire harness plug to approach the detection socket 502. When the wire harness plug is inserted into the detection socket 502, the first elastic locking plate 503 on both sides of the detection socket 502 fits with the second spring locking plate 1204 on both sides of the wire harness fixing groove 1203. The first locking ring 504 and the second locking ring 1205 automatically engage, realizing the locking and positioning of the plug and the detection socket 502, and preventing loosening during insertion and removal. The controller 4 simultaneously detects the docking status and starts after confirming that the docking is qualified.

[0036] When the number of insertion and removal cycles recorded by the controller 4 reaches the preset value, a stop command is issued, the motor 7 stops running, the lead screw 8 drives the connecting rod 9 and the self-insertion and removal wire harness fixing mechanism 12 to return to the initial position, and the first retaining ring 504 and the second retaining ring 1205 remain separated.
