Description

Technical Field

[0001] This utility model relates to the field of wire harness testing technology, and in particular to a testing fixture and wire harness testing equipment. Background Technology

[0002] In the field of medical device technology, the operating and control ends of equipment are typically connected via wiring harnesses. Specifically, a wiring harness usually has two connectors: one for connecting the operating end and the other for connecting the control end, enabling communication between the two. The wiring harness requires performance testing before being put into use.

[0003] In existing technologies, wire harness testing equipment is used to perform performance tests on wire harnesses. This equipment includes a test socket with jacks that mate with the wire harness plugs. However, for certain plugs, which typically have multiple connection terminals arranged irregularly, manual insertion into the test socket is required during testing. This manual insertion method, requiring alignment of each connection terminal and plug, results in low testing efficiency and high labor intensity.

[0004] Therefore, there is an urgent need for a testing fixture and wire harness testing equipment to solve the above problems. Utility Model Content

[0011] A test socket is disposed opposite to the plug positioning carrier in a first direction, and the test socket has a socket.

[0012] A first driving component is used to drive the test socket and / or the plug positioning carrier to move in the first direction, so that the test socket and the plug positioning carrier move closer to each other or further apart.

[0015] In one embodiment, the centering clamping assembly further includes a connector, two clamping members are spaced apart and both are connected to the connector, and the second driving assembly is driven to be connected to the connector.

[0016] In one embodiment, the second driving component includes a first driving member, the output of which is connected to the connector;

[0017] Alternatively, the second driving component includes a second driving member and two elastic members. The test fixture also includes a support base. The plug positioning carrier is disposed on the support base. A sliding groove is formed on the connector. The output end of the second driving member is disposed in the sliding groove. The two elastic members correspond one-to-one with the two clamping members. One end of each elastic member abuts against the support base, and the other end of the elastic member abuts against the corresponding clamping member. The direction in which the second driving member drives the clamping member to move is opposite to the direction in which the elastic members drive the clamping member to move.

[0018] In one embodiment, the top surfaces of the two clamping members of the centering clamping assembly located at the clamping position are flush with the top surface of the plug positioning carrier.

[0019] And / or, the top surfaces of the two clamping members of the centering clamping assembly located at the clamping position are both located between the top surface of the plug positioning carrier and the bottom surface of the preliminary positioning groove;

[0020] And / or, the top surfaces of the two clamping members of the centering clamping assembly located in the released position are flush with the bottom surface of the initial positioning groove.

[0021] In one embodiment, the through hole is located at one end of the plug positioning carrier facing the test socket.

The centering clamping component can further adjust the position of the plug and control the plug to remain in the test position. The first driving component can drive the test socket and the plug positioning carrier to move closer to each other so that the terminals on the plug at the test position can be inserted into the socket of the test socket. In this process, the step requiring manual intervention is to place the plug into the preliminary positioning groove. The centering of the plug is achieved by the centering clamping component, and the insertion of the plug into the test socket is achieved by the first driving component. Compared with the manual insertion method, it has higher insertion efficiency. In addition, by setting the centering clamping component, the insertion accuracy can also be improved, so that the terminals can be smoothly inserted into the socket, reducing the intensity of manual labor and improving the testing efficiency.

[0045] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] Firstly, this embodiment provides a testing fixture for testing wire harnesses, reducing manual steps, improving testing efficiency, and reducing labor intensity.

[0047] The wire harness has at least one plug; for example, the structure of the plug can be seen in [reference needed]. Figure 6 The plug 1 has a cable end 13 and a plug end disposed opposite each other, wherein the cable end is connected to a cable, and the plug end is provided with a terminal 11. The main body of the plug has a protrusion 12.

[0048] like Figures 1 to 6 As shown, the test fixture 10 includes a plug positioning carrier 100, a centering clamping assembly 200, a test female connector 300, and a first drive assembly 400. The plug positioning carrier 100, the test female connector 300, and the first drive assembly 400 are all mounted on a platform. In some optional embodiments, the test fixture 10 further includes a support base 600, on which the plug positioning carrier 100, the test female connector 300, and the first drive assembly 400 are all mounted.

[0049] For example, such as Figure 1 As shown, the plug positioning carrier 100 is provided with a preliminary positioning groove 110 for accommodating the plug 1. The preliminary positioning groove 110 can be used to perform preliminary positioning of the plug 1. For example, the shape of the preliminary positioning groove 110 is approximately the same as the shape of the plug 1. In order to facilitate the insertion of the plug 1 into the preliminary positioning groove 110, the width of the preliminary positioning groove 110 is slightly larger than the width of the plug 1, which causes the plug 1 to have a misalignment problem with the test socket 300.

[0050] In this embodiment, the centering clamping assembly 200 is movably connected to the plug positioning carrier 100. That is, the centering clamping assembly 200 is movable relative to the plug positioning carrier 100, and it has a clamping position and a released position relative to the plug positioning carrier 100. When the centering clamping assembly 200 is in the clamping position, it clamps the plug 1 in the preliminary positioning groove 110, holding the plug 1 in the test position, thereby enabling alignment with the test socket 300. When the centering clamping assembly 200 is in the released position, it no longer clamps the plug 1. Figure 2 As shown, the test socket 300 is positioned opposite the plug positioning carrier 100 in the first direction X, as follows: Figure 4As shown, the test socket 300 has a socket 310 for inserting the terminals 11 of the plug 1 to achieve electrical connection between the test socket 300 and the plug 1. In this embodiment, there can be multiple sockets 310, which can be arranged regularly or irregularly, and the positions of the sockets 310 match the positions of the terminals 11 on the plug 1, so that the terminals 11 on the plug 1 can be inserted into the sockets 310 one by one.

[0051] In this embodiment, the first driving component 400 is used to drive the test socket 300 and / or the plug positioning carrier 100 to move in the first direction X, so that the test socket 300 and the plug positioning carrier 100 move closer to each other or further apart. When the test socket 300 and the plug positioning carrier 100 move closer to each other, the terminal 11 of the plug 1 located at the test position can be inserted into the socket 310; when the test socket 300 and the plug positioning carrier 100 move further apart, the terminal 11 can be pulled out of the socket 310.

[0052] In some optional embodiments, the first driving component 400 may include a driving element whose output end is connected to the test socket 300 or the plug positioning carrier 100, and is used to drive the test socket 300 to move closer to or away from the plug positioning carrier 100, or to drive the plug positioning carrier 100 to move closer to or away from the test socket 300. Figure 2 The first drive assembly 400 includes a drive member, and the output end of the drive member is connected to the test socket 300. In other embodiments, the first drive assembly 400 includes two drive members, which are respectively connected to the test socket 300 and the plug positioning carrier 100, and are used to drive the test socket 300 and the plug positioning carrier 100 to move closer to or further away from each other.

[0053] Optionally, in order to improve the stability of the movement of the test socket 300 or the plug positioning carrier 100 and to ensure that the test socket 300 and the plug positioning carrier 100 move in the first direction X, the test fixture 10 also includes a slide rail slider assembly (not shown in the figure), wherein the slide rail of the slide rail slider assembly is disposed on the support base 600, and the slider is connected to the test socket 300 or the plug positioning carrier 100.

[0054] When using the test fixture provided in this embodiment, the centering clamping assembly 200 is first controlled to be in the released position, and then the plug 1 of the cable is placed into the preliminary positioning slot 110 for preliminary positioning. Afterwards, the centering clamping assembly 200 is controlled to move from the released position to the clamping position. As the centering clamping assembly 200 moves to the clamping position, the position of the plug 1 can be adjusted again, so that the plug 1 can be located in the test position, and the centering clamping assembly 200 can clamp the plug 1 located in the test position. The terminal 11 of the plug 1 located in the test position can be smoothly inserted into the socket 310 of the test female connector 300. Next, the first drive assembly 400 drives the test female connector 300 and the plug positioning carrier 100 to move closer to each other in the first direction X, so that the terminal 11 can be inserted into the socket 310. At this time, the wire harness can be subjected to performance testing.

[0055] The test fixture 10 provided in this embodiment allows the plug 1 to be mounted on the plug positioning carrier 100 and initially positioned by the initial positioning groove 110. The centering clamping component 200 can further adjust the position of the plug 1 and control the plug 1 to remain in the test position. The first driving component 400 can drive the test socket 300 and the plug positioning carrier 100 to move closer to each other, so that the terminal 11 on the plug 1 in the test position can be inserted into the socket 310 of the test socket 300. In this process, the step requiring manual intervention is to place the plug 1 into the initial positioning groove 110, and the centering of the plug 1 is achieved by the centering clamping component 200. The insertion of the plug 1 into the test socket 300 is achieved by the first driving component 400. Compared with the manual insertion method, it has higher insertion efficiency. Furthermore, by setting the centering clamping component 200, the insertion accuracy can also be improved, so that the terminal 11 can be smoothly inserted into the socket 310, reducing the intensity of manual labor and improving the testing efficiency.

[0056] To further reduce the number of steps requiring manual intervention, in some possible implementations, such as Figure 1 As shown, the test fixture 10 also includes a second drive assembly 500. The second drive assembly 500 is connected to the centering clamping assembly 200 and is used to drive the centering clamping assembly 200 to move in the second direction Z, allowing the centering clamping assembly 200 to move between a clamping position and a releasing position. The second direction Z is perpendicular to the first direction X. For example, the second direction Z can be a vertical direction, the thickness direction of the plug 1 located in the preliminary positioning groove 110 is the second direction Z, the length direction of the plug 1 is the first direction X, and the width direction of the plug 1 is the third direction Y. By setting the second drive assembly 500, the centering clamping assembly 200 can move in the second direction Z under the drive of the second drive assembly 500, thereby moving from the clamping position to the releasing position and from the releasing position to the clamping position.

[0057] The specific structure of the centering clamping component 200 can be varied, for example, such as Figure 2 As shown, the centering clamping assembly 200 includes two clamping members 210. The two clamping members 210 are arranged opposite each other in the third direction Y to clamp the plug 1 in the width direction. The second drive assembly 500 is drivenly connected to the two clamping members 210 and can drive the two clamping members 210 to move in the second direction Z. The plug positioning carrier 100 is provided with two through holes 120 along the second direction Z. The two clamping members 210 correspond one-to-one with the two through holes 120. The clamping members 210 are movably inserted through the corresponding through holes 120, so that the clamping members 210 can move relative to the plug positioning carrier 100 in the second direction Z, thereby realizing movement between the clamping position and the releasing position. Both through holes 120 are connected to the preliminary positioning groove 110, and both clamping members 210 are provided to protrude from the groove sidewall of the preliminary positioning groove 110, so that the two clamping members 210 can cooperate with each other to adjust the centering of the plug 1 in the preliminary positioning groove 110 and clamp the plug 1.

[0058] By providing two clamping members 210, it is easy to adjust the alignment of the plug 1, so that the terminals 11 of the plug 1 can be smoothly inserted into the socket 310 of the test socket 300. The clamping member 210 is movably inserted into the through hole 120 of the plug positioning carrier 100, so that the through hole 120 can guide the movement of the clamping member 210 in the second direction Z, ensuring that the clamping member 210 can move in the second direction Z, thereby ensuring the effect of the clamping member 210 in adjusting the alignment of the plug 1. In some optional embodiments, the part of the clamping member 210 that contacts the plug 1 is made of a material with low hardness to avoid scratching or abrading the plug 1. For example, the material of the part of the clamping member 210 that contacts the plug 1 can be plastic, silicone, rubber, etc., and this embodiment does not limit this.

[0059] To reduce the number of drive components in the second drive assembly 500, for example, such as Figure 3 As shown, the centering clamping assembly 200 also includes a connector 220. Two clamping members 210 are spaced apart in the third direction Y and both are connected to the connector 220. The second driving assembly 500 is driven and connected to the connector 220. Thus, the second driving assembly 500 can have only one driving member, which can drive both clamping members 210, reducing the number of parts in the test fixture 10 and lowering structural complexity.

[0060] In one embodiment, such as Figure 1As shown, the second drive assembly 500 includes a first drive member 510, the output end of which is connected to the connector 220. Thus, the second drive assembly 500 includes only one first drive member 510, and the centering clamping assembly 200 is driven by this first drive member 510 to move from the clamping position to the releasing position and from the releasing position to the clamping position.

[0061] In other embodiments, such as Figure 3 As shown, the second drive assembly 500 includes a second drive member 520 and two elastic members 530. The plug positioning carrier 100 is mounted on the support base 600. A sliding groove 230 is provided on the connector 220. The output end of the second drive member 520 is disposed within the sliding groove 230, allowing it to slide relative to the other end within the groove to drive the two clamping members 210 from a released position to a clamping position. The two elastic members 530 correspond one-to-one with the two clamping members 210. One end of each elastic member 530 abuts against the support base 600, and the other end of each elastic member 530 abuts against the corresponding clamping member 210. The elastic members 530 extend along the second direction Z and can drive the clamping members 210 to move in the second direction Z, from the clamping position to the released position. In this embodiment, the direction in which the second driving member 520 drives the clamping member 210 to move is opposite to the direction in which the elastic member 530 drives the clamping member 210 to move. The second direction Z is the vertical direction. When the clamping member 210 is in the released position, the second driving member 520 does not apply force to the connecting member 220, and the clamping member 210 squeezes the elastic member 530. When the clamping member 210 needs to move from the released position to the clamping position, the output end of the second driving member 520 moves along the second direction Z toward the plug positioning carrier 100, abuts against the inner wall of the sliding groove 230, and drives the connecting member 220 to move upward. The clamping member 210 moves to the clamping position. At this time, the elastic member 530 is in a stretched state. When the clamping member 210 moves from the clamping state to the released state, the output end of the second driving member 520 retracts downward along the second direction Z. Under the action of its own weight and the rebound force of the elastic member 530, the clamping member 210 moves to the released position.

[0062] Furthermore, the support base 600 includes two support columns (not shown in the figure) arranged opposite each other in the third direction Y, and each support column has a groove 610 on its side wall, and the end of the elastic member 530 abuts against the bottom wall of the groove 610.

[0063] It should be noted that the driving components in this embodiment can all be linear drive components such as cylinders and linear motors, and this embodiment does not limit them.

[0064] Exemplarily, in one embodiment, such as Figure 1As shown, when the centering clamping assembly 200 is in the clamping position, the top surfaces of both clamping members 210 are flush with the top surface of the plug positioning carrier 100, so as to observe whether the clamping members 210 extend, and thus determine whether the clamping members 210 have centered and adjusted the plug 1.

[0065] In other embodiments, the top surfaces of the two clamping members 210 may also be located between the top surface of the plug positioning carrier 100 and the bottom surface of the initial positioning groove 110. That is, the top surface of the clamping member 210 is located below the top surface of the plug positioning carrier 100, as long as it can clamp the plug 1.

[0066] Optionally, such as Figure 4 As shown, when the centering clamping assembly 200 is in the released position, the top surfaces of both clamping members 210 are flush with the bottom surface of the preliminary positioning groove 110. In this way, when the plug 1 is placed in the preliminary positioning groove 110, the plug 1 will not be unable to be supported on the bottom surface of the preliminary positioning groove 110 due to the support of the clamping members 210. This facilitates the centering adjustment of the plug 1 in the third direction Y when the clamping members 210 extend, ensuring the smooth operation of the centering adjustment.

[0067] To further improve the adjustment effect of the centering clamping assembly 200 on the plug 1, in this embodiment, the through hole 120 is provided at one end of the plug positioning carrier 100 facing the test socket 300. That is, the clamping member 210 is provided near the end of the plug positioning carrier 100 facing the test socket 300, so that the centering clamping assembly 200 can adjust the terminal end of the plug 1, so that the position of the terminal end can meet the requirement of inserting the terminal 11 into the socket 310 of the test socket 300, so that the terminal 11 can be successfully inserted into the socket 310 of the test socket 300.

[0068] like Figure 6 As shown, a protrusion 12 is provided on one surface of the plug 1 in the thickness direction. In order to ensure that the surface of the plug 1 in the thickness direction can contact the bottom surface of the initial positioning groove 110 in a face-to-face manner, for example, as shown... Figure 2 As shown, the bottom surface of the initial positioning groove 110 is provided with a clearance hole 130. The clearance hole 130 is used to avoid the protrusion 12 on the side wall of the plug 1. That is, the protrusion 12 is located in the clearance hole 130, so that the plug 1 can be stably located in the initial positioning groove 110.

[0069] In some alternative embodiments, the cable end 13 of the plug 1 is typically connected to a cable. To ensure that the plug 1 lies flat in the initial positioning groove 110 and that the cable end 13 does not tilt up, please refer to [the following text is incomplete and requires further context]. Figure 2The plug positioning carrier 100 is provided with a cable groove 140 that connects to the preliminary positioning groove 110. The cable groove 140 is disposed on the top surface of the plug positioning carrier 100 and extends to the surface of the plug positioning carrier 100 facing away from the test socket 300. The cable groove 140 is used to position the cable end 13 of the plug 1, preventing the cable end 13 from moving during the test. In this embodiment, the shape of the cable groove 140 is the same as the shape of the cable end 13 to firmly limit the cable end 13. For example, along the direction of the plug positioning carrier 100 facing away from the test socket 300, the width of the cable groove 140 gradually decreases to match the gradually decreasing width of the cable end 13.

[0070] To ensure that the position of plug 1 in the second direction Z meets the requirements, in one embodiment, the test fixture 10 further includes a clamping drive (not shown in the figure) and a pressing end (not shown in the figure) connected to the clamping drive. The clamping drive drives the pressing end to move in the second direction Z, pressing plug 1 into the preliminary positioning groove 110 in the second direction Z. This ensures the uniqueness of the plug 1's position in the second direction Z, thereby ensuring that the position of plug 1 meets the requirements. This allows the terminals 11 on plug 1 to be inserted into the corresponding sockets 310, further improving the automation and efficiency of the test fixture 10. For example, the clamping drive can be a cylinder or similar component, and the pressing end can be made of a softer material, such as silicone, rubber, or plastic, to prevent the pressing end from damaging plug 1.

[0071] It is understood that in other embodiments, the test fixture 10 may not include a clamping drive, but instead the plug 1 may be manually pressed to limit the position of the plug 1 in the second direction Z. This embodiment does not limit this.

[0072] The test fixture 10 provided in this embodiment has a simple structure, is easy to operate, and has high reliability.

[0073] Secondly, this embodiment also provides a wire harness testing device with high testing efficiency.

[0074] like Figure 7 As shown, the wire harness testing equipment includes the test fixture 10 as described in the first aspect. The wire harness testing equipment also includes a tester 20, which is electrically connected to the test socket 300 for testing the wire harness.

[0075] Wire harness testing equipment includes Figure 1 Taking the test fixture 10 shown as an example, the method of using the wire harness testing equipment provided in this embodiment is as follows:

[0076] The first drive unit 510 is controlled to move, causing the two clamping members 210 to move downwards until the centering clamping assembly 200 moves from the clamping position to the released position. At this time, the test fixture 10 is in the position of Figure 4The state shown is as follows. Next, the plug 1 is placed in the initial positioning groove 110, and the cable end 13 of the plug 1 is positioned in the cable groove 140, with the protrusion 12 of the plug 1 placed in the clearance hole 130. At this time, if the terminals 11 of the plug 1 are irregularly arranged, it is necessary to determine whether the plug 1 is facing upwards. If not, the orientation of the plug 1 needs to be adjusted to ensure that the terminals 11 can be inserted into the corresponding sockets 310.

[0077] Next, the first drive component 510 is activated, causing the two clamping components 210 to move upwards until the centering clamping assembly 200 is in the clamping position. During the upward movement of the clamping components 210, the position of the plug 1 in the third direction Y is adjusted by pushing the two sidewalls in the width direction of the plug 1, so that the plug 1 is in the test position. During this process, the plug 1 can be manually pressed into the preliminary positioning groove 110 to limit the plug 1 in the second direction Z. Next, the first drive component 400 is activated to drive the test socket 300 to move closer to the plug positioning carrier 100 until the terminal 11 is inserted into the socket 310 and properly connected. Afterwards, the wire harness is tested by the testing machine 20.

[0078] After the test is completed, the test socket 300 is first moved away from the plug positioning carrier 100 by the first drive component 400 until the terminal 11 exits the socket 310. Then the plug 1 can be directly pulled out of the preliminary positioning groove 110, that is, a force greater than that of the two clamping members 210 is applied to the plug 1. Alternatively, the centering clamping component 200 can be moved to the release position by the first drive component 510, and then the plug 1 can be pulled out of the preliminary positioning groove 110 to complete the wire harness test.
