Description

Technical Field

[0001] The present invention relates to the technical field of wire harness connector testing, in particular to a modular reconfigurable wire harness connector testing platform. Background Art

[0002] A wiring harness connector is a type of terminal. A connector is also called a plug-in connector. It consists of a plug and a socket. A connector is a relay station for wiring harnesses in a circuit. Connectors are generally used to connect wiring harnesses and wiring harnesses, or wiring harnesses and electrical components.

[0003] For example, CN105182098A involves a universal test fixture for detecting wiring harnesses, which includes an installation operation platform, which includes several detection circuit boards for wiring harnesses of different specifications. The circuits on the detection circuit boards are the same, and the connectors at one end of the detection circuit boards for wiring harnesses of different specifications are integrated with corresponding docking connectors. Two slide rails are arranged in parallel on the installation operation platform, and an error-proofing test device that is connected to the jack connector at the other end of the wiring harness to be tested is arranged at one end of the two slide rails. The detection circuit board is arranged between the two slide rails. The detection circuit board and the error-proofing test device are electrically connected to a test machine for performing electrical testing on the wiring harness to be tested. The error-proofing test device includes a base, and the base is provided with a row of pins that can meet the docking requirements of jack connectors of different specifications.

[0004] There are many specifications of wiring harness connectors, and the above-mentioned test fixture is equipped with a dedicated detection circuit board corresponding to the different specifications of the wiring harness. The problem is that only one circuit board is activated and used during the test, and the rest are idle. The utilization rate of the module is low, and the same functional circuit is repeatedly manufactured, which doubles the material cost. Summary of the Invention

[0005] The purpose of the present invention is to avoid the problem of low module utilization caused by providing circuit boards corresponding to wiring harness connectors of different specifications in the prior art.

[0006] The purpose of the present invention is to provide a modular reconfigurable wiring harness connector test platform. By providing a plurality of pins and jacks, when in use, pins or jacks of different numbers and shapes are spliced ​​and combined according to the specifications of the wiring harness connector to form a structure corresponding to the specifications of the wiring harness connector, thereby improving the utilization rate of the module.

[0007] To achieve the above object, the present invention provides a modular reconfigurable wiring harness connector test platform, comprising a test host and an electrical connection device, wherein the electrical connection device comprises a base and a reconfigurable body disposed on the base;

[0008] The base includes a bottom platform, a vertical plate and an electrical connection module for matching the wiring harness connector plug or jack, and the electrical connection module is also electrically connected to the test host;

[0009] The reconstructed body includes an adjustment structure and a pre-pressing structure and a pressing structure that are transmission-connected to the adjustment structure. The adjustment structure is rotationally connected to the top of the vertical plate, the pre-pressing structure is horizontally slidingly connected to the inner wall of the vertical plate, and the pressing structure is vertically slidingly connected to the inner wall of the vertical plate.

[0010] After setting the electrical connection module according to the specifications of the wiring harness connector plug or socket, rotate the adjustment structure, and the adjustment structure drives the pre-stressing structure to slide horizontally from both sides to the middle along the inner wall of the vertical plate. At the same time, the adjustment structure drives the pressing structure to slide vertically from both sides to the middle along the inner wall of the vertical plate until the pre-stressing structure and the pressing structure fix the electrical connection module. Align the wiring harness connector with the electrical connection module so that the pins or sockets of the wiring harness connector are electrically connected to the electrical connection module. Finally, the test host performs a performance test on the wiring harness connector.

[0011] As a further improvement of the present technical solution, the electrical connection module includes multiple component shells and conductive parts arranged in the component shells. The conductive parts are sockets or pins that match the pins or sockets of the wiring harness connector. The conductive parts are electrically connected to the test host through wires. Two adjacent surfaces of the component shells are provided with second card blocks, and the other two adjacent surfaces are correspondingly provided with card slots. The second card block is plugged into the card slot.

[0012] Furthermore, the base also includes a placement rack fixedly arranged on both sides of the vertical plate, and the placement rack is used to store the component shell.

[0013] According to the specifications of the wiring harness connector to be tested, remove the corresponding number of component shells whose conductive parts match the pins or sockets of the wiring harness connector from the placement rack, then arrange and combine multiple component shells according to the positions of the pins or sockets of the wiring harness connector, and insert the corresponding second card blocks into the card slots of adjacent component shells for pre-splicing, so as to obtain an electrical connection module that matches the specifications of the wiring harness connector.

[0014] As a further improvement of the present technical solution, the vertical plate is an "O"-shaped structural plate whose bottom is plugged into the base, and plate grooves are provided on the left and right sides of the vertical plate. The placement rack includes a slide body and a plurality of grille plates arranged at equal intervals on the surface of the slide body, and the spacing between adjacent grille plates matches the thickness of the component shell.

[0015] Furthermore, a shell groove is provided in the middle of the surface of the component shell, and correspondingly, a first clamping block is provided on the contact surface between the grid plate and the component shell, and the first clamping block is engaged with the shell groove.

[0016] The component shell is stuck in the space formed by the adjacent grid plates to prevent the component shell from accidentally falling off.

[0017] As a further improvement of the present technical solution, the adjustment structure includes an adjustment knob and a first transmission rod engaged with the bottom end of the adjustment knob, the top of the adjustment knob passes through the outer wall of the vertical plate and is rotatably connected to the vertical plate, the first transmission rod is rotatably connected to the vertical plate, and the pre-stressing structure includes two first movable plates and a pre-stressing plate arranged on the side of the first movable plate close to the adjustment knob. The two first movable plates are horizontally symmetrically arranged on the inner wall of the vertical plate and are horizontally slidingly connected to the inner wall of the vertical plate. The first transmission rod is threadedly connected to the first movable plate, and the pre-stressing plate is used to contact the electrical connection module.

[0018] Furthermore, the contact surface between the pre-stressing plate and the electrical connection module is provided with a soft pad for increasing friction. By turning the adjusting knob, the adjusting knob drives the first transmission rod to rotate, and the rotation of the first transmission rod drives the first movable plate to slide horizontally along the inner wall of the vertical plate toward the electrical connection module until the pre-stressing plates of the two first movable plates contact and clamp the electrical connection module. Then, the hand holding the electrical connection module is released, and the pre-stressing plate ensures friction on the electrical connection module through the provided soft pad.

[0019] As a further improvement of the present technical solution, the pressing structure includes a second transmission rod and two second movable plates threadedly connected to the second transmission rod. The second transmission rod is rotatably connected to both sides of the inner wall of the vertical plate, and the top end of the second transmission rod is engaged with the end of the first transmission rod away from the adjustment knob, and the two ends of the second movable plate are vertically slidably connected to the inner wall of the vertical plate.

[0020] In the process of turning the adjusting knob so that the first transmission rod drives the first movable plate to slide horizontally along the inner wall of the vertical plate toward the electrical connection module, the first transmission rod synchronously drives the second transmission rod to rotate, and the second transmission rod then drives the two second movable plates to slide vertically along the inner wall of the vertical plate toward the electrical connection module. When the two pre-pressing plates contact and clamp the electrical connection module, the two second movable plates also contact and clamp the electrical connection module.

[0021] As a further improvement of the present technical solution, a limiting rod is provided on the back side of the pre-stressing plate, one end of the limiting rod passes through the first movable plate and is engaged with the first movable plate, a limiting spring is sleeved on the surface of the limiting rod, and the pre-stressing plate is elastically connected to the first movable plate through the provided limiting spring. When the pre-stressing plate contacts the electrical connection module, the limiting rod can still slide horizontally, thereby facilitating the second movable plate to move and contact the fixed electrical connection module.

[0022] As a further improvement of the present technical solution, a limiting groove for locking the shell groove is provided on the contact surface between the second movable plate and the electrical connection module to prevent the electrical connection module from being displaced.

[0023] In the present invention, multiple component shells are arranged and combined according to the specifications of the wiring harness connector to be tested to obtain an electrical connection module that matches the specifications of the wiring harness connector. The testing host then performs a performance test on the wiring harness connector, and the modular utilization rate of the component shells is high.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In the modular reconfigurable wiring harness connector test platform, according to the specifications of the wiring harness connector to be tested, a corresponding number of component shells with conductive parts matching the pins or sockets of the wiring harness connector are removed from the placement rack, and then multiple component shells are arranged and combined according to the positions of the pins or sockets of the wiring harness connector, and the corresponding second card blocks are inserted into the card slots of adjacent component shells for pre-splicing, so as to obtain an electrical connection module that matches the specifications of the wiring harness connector. When testing different wiring harness connectors, it is only necessary to select the corresponding component shell according to the specifications of the wiring harness connector, and arrange and combine the component shells accordingly to obtain an electrical connection module that matches the wiring harness connector. The modular utilization rate of the component shell is high and the material cost is low.

[0026] 2. In the modular reconfigurable wiring harness connector test platform, in the process of turning the adjustment knob to make the first transmission rod drive the first movable plate to slide horizontally along the inner wall of the vertical plate toward the electrical connection module, the first transmission rod synchronously drives the second transmission rod to rotate, and the second transmission rod then drives the two second movable plates to slide vertically along the inner wall of the vertical plate toward the electrical connection module. When the two pre-compression plates contact and clamp the electrical connection module, the two second movable plates also contact and clamp the electrical connection module. Under the clamping action in two directions, namely horizontal and vertical directions, the electrical connection module can be pressed together, and multiple component shells can be squeezed into a stable whole, thereby avoiding the loosening of single or multiple component shells when connecting the wiring harness connector.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0042] See also Figure 1 、 Figure 2 、 Figure 6 As shown, the purpose of this embodiment is to provide a modular reconfigurable harness connector test platform, including a test host and an electrical connection device, the electrical connection device including a base 1 and a reconfigurable body 2 provided on the base 1;

[0043] The base 1 includes a bottom platform 11, a vertical plate 12 and an electrical connection module 14 for matching the plug or jack of the wiring harness connector. The electrical connection module 14 is also electrically connected to the test host.

[0044] The reconstruction body 2 includes an adjustment structure and a pre-pressing structure 23 and a pressing structure 24 that are transmission-connected to the adjustment structure. The adjustment structure is rotationally connected to the top of the vertical plate 12, the pre-pressing structure 23 is horizontally slidingly connected to the inner wall of the vertical plate 12, and the pressing structure 24 is vertically slidingly connected to the inner wall of the vertical plate 12.

[0045] After setting the electrical connection module 14 according to the specifications of the wiring harness connector plug or socket (the number and shape of the plug or jack), lift the electrical connection module 14 and place it in the vertical plate 12, and rotate the adjustment structure. The adjustment structure drives the pre-pressing structure 23 to slide horizontally from both sides to the middle along the inner wall of the vertical plate 12. The adjustment structure also drives the pressing structure 24 to slide vertically from both sides to the middle along the inner wall of the vertical plate 12 until the pre-pressing structure 23 and the pressing structure 24 fix the electrical connection module 14 to ensure the stability of the electrical connection module 14. Then, align the wiring harness connector with the electrical connection module 14 so that the pins or jacks of the wiring harness connector are electrically connected to the electrical connection module 14. Finally, the test host performs a performance test on the wiring harness connector.

[0046] The above structure is disclosed below:

[0047] Considering that different wiring harness connectors have different specifications, that is, the number and shape of pins or sockets of different wiring harness connectors are different, it is necessary to match the wiring harness connector to be tested before performing performance testing, such as Figure 2 、 Figure 3 、 Figure 4As shown, the electrical connection module 14 includes a plurality of component shells 141 and a conductive member 142 arranged in the component shell 141. The conductive member 142 is a socket or pin that matches the pin or socket of the wiring harness connector. The conductive member 142 is electrically connected to the test host through a wire. Two adjacent surfaces of the four surfaces of the component shell 141 are provided with a second card block 1411, and the other two adjacent surfaces of the four surfaces of the component shell 141 are correspondingly provided with a card slot. The second card block 1411 is plugged into the card slot. In addition, the base 1 also includes a placement rack 13 fixedly arranged on both sides of the vertical plate 12. The placement rack 13 is used to store the component shell 141. According to the specifications of the wiring harness connector to be tested, a corresponding number of components are removed from the placement rack 13. And the conductive part 142 is a component shell 141 that matches the pin or socket of the wiring harness connector, and then multiple component shells 141 are arranged and combined according to the pin or socket positions of the wiring harness connector, and the corresponding second card block 1411 is inserted into the card slot of the adjacent component shell 141 for pre-splicing, so as to obtain an electrical connection module 14 that matches the specifications of the wiring harness connector. The electrical connection module 14 obtained according to this reconstruction method has the advantage that when testing different wiring harness connectors, it is only necessary to select the corresponding component shell 141 according to the specifications of the wiring harness connector, and the component shell 141 is arranged and combined accordingly to obtain the electrical connection module 14 that matches the wiring harness connector. The modular utilization rate of the component shell 141 is high and the material cost is low.

[0048] Among them, such as Figure 2 、 Figure 4 、 Figure 5 As shown, the vertical plate 12 is an "O"-shaped structural plate whose bottom is plugged into the base 11. Plate grooves 121 are provided on the left and right sides of the vertical plate 12. The placement rack 13 includes a slide body and a plurality of grid plates 131 arranged at equal intervals on the surface of the slide body. The spacing between adjacent grid plates 131 matches the thickness of the component shell 141. Further, a shell groove 1412 is provided in the middle of the surface of the component shell 141. Correspondingly, a first block 132 is provided on the contact surface between the grid plate 131 and the component shell 141. The first block 132 is connected to the shell The slot 1412 is snap-fitted. Under normal circumstances, the component shell 141 is temporarily stored in the gap between the adjacent grid plates 131. When taking the component shell 141, the component shell 141 can be taken out from the gap between the adjacent grid plates 131. The purpose of setting the first snap-fitting block 132 and the shell slot 1412 is to clamp the component shell 141 in the space formed by the adjacent grid plates 131 while ensuring that the component shell 141 is movable, so as to avoid accidental falling off of the component shell 141 and facilitate the management of multiple component shells 141.

[0049] After setting the electrical connection module 14 that matches the specifications of the wiring harness connector, it is necessary to press the electrical connection module 14 to ensure that the multiple component shells 141 in the electrical connection module 14 can form a stable whole, so as to avoid the loosening of the component shells 141 in the electrical connection module 14 when the pins or sockets of the electrical connection module 14 contact the wiring harness connector. Figure 6 、 Figure 7 As shown, the adjustment structure includes an adjustment knob 21 and a first transmission rod 22 engaged with the bottom end of the adjustment knob 21. The top end of the adjustment knob 21 passes through the outer wall of the vertical plate 12 and is rotatably connected to the vertical plate 12. The first transmission rod 22 is located inside the vertical plate 12 and is rotatably connected to the vertical plate 12. The pre-pressing structure 23 includes two first movable plates 231 and a pre-pressing plate 232 arranged on the side of the first movable plate 231 close to the adjustment knob 21. The two first movable plates 231 are horizontally symmetrically arranged on the inner wall of the vertical plate 12 and are horizontally slidably connected to the inner wall of the vertical plate 12. The first transmission rod 22 is located inside the vertical plate 12 and is rotatably connected to the vertical plate 12. The end passes through the first movable plate 231 and is threadedly connected to the first movable plate 231. The pre-pressing plate 232 is used to contact the electrical connection module 14. The contact surface between the pre-pressing plate 232 and the electrical connection module 14 is provided with a soft pad for increasing friction. With one hand, the set electrical connection module 14 is placed in the middle of the "O"-shaped area of ​​the vertical plate 12, and then the other hand turns the adjusting knob 21, so that the adjusting knob 21 drives the first transmission rod 22 to rotate. The rotation of the first transmission rod 22 drives the first movable plate 231 to slide horizontally along the inner wall of the vertical plate 12 toward the electrical connection module 14. Figure 9 As shown by the middle arrow a, until the pre-compression plates 232 of the two first movable plates 231 contact and clamp the electrical connection module 14, release the hand holding the electrical connection module 14. The pre-compression plates 232 ensure friction on the electrical connection module 14 through the provided soft pads to prevent the electrical connection module 14 from sliding.

[0050] In the process of the first movable plate 231 slidingly clamping the electrical connection module 14, as shown in FIG. Figure 6 、 Figure 8 As shown, the pressing structure 24 includes a second transmission rod 241 and two second movable plates 242 threadedly connected to the second transmission rod 241, the second transmission rod 241 is rotatably connected to both sides of the inner wall of the vertical plate 12, and the top of the second transmission rod 241 is engaged with the end of the first transmission rod 22 away from the adjusting knob 21, and the two ends of the second movable plates 242 are vertically slidably connected to the inner wall of the vertical plate 12. When the adjusting knob 21 is rotated to make the first transmission rod 22 drive the first movable plate 231 to slide horizontally along the inner wall of the vertical plate 12 toward the electrical connection module 14, the first transmission rod 22 synchronously drives the second transmission rod 241 to rotate, and the second transmission rod 241 further drives the two second movable plates 242 to slide vertically along the inner wall of the vertical plate 12 toward the electrical connection module 14, as shown in FIG. Figure 9As shown by the middle arrow b, when the two pre-compression plates 232 contact and clamp the electrical connection module 14, the two second movable plates 242 also contact and clamp the electrical connection module 14. Under the clamping action in two directions, namely horizontally and longitudinally, the electrical connection module 14 can be pressed together, and the multiple component shells 141 can be squeezed to form a stable whole, thereby avoiding the situation where a single or multiple component shells 141 become loose when connecting the wiring harness connector.

[0051] It is worth noting that in addition to the number and shape of pins or sockets, the specifications of different wiring harness connectors also have different port shapes. When testing a wiring harness connector with a flat port shape such as an HDMI cable interface, when fixing the electrical connection module 14 with a corresponding flat shape, the pre-pressing plate 232 may have contacted and clamped the electrical connection module 14, while the second movable plate 242 has not yet contacted the electrical connection module 14. Therefore, if Figure 7 As shown, a limiting rod 233 is provided on the back side of the pre-stressing plate 232, and one end of the limiting rod 233 passes through the first movable plate 231 and is engaged with the first movable plate 231, and a limiting spring 234 is sleeved on the surface of the limiting rod 233, and the pre-stressing plate 232 is elastically connected to the first movable plate 231 through the provided limiting spring 234. By setting the elastic connection, the first movable plate 231 obtains a certain movable space, that is, when the elongated electrical connection module 14 is fixed, even when the pre-stressing plate 232 contacts the electrical connection module 14, the limiting rod 233 can still slide horizontally, thereby facilitating the second movable plate 242 to move and contact the fixed electrical connection module 14, and the contact surface of the second movable plate 242 and the electrical connection module 14 is provided with a limiting groove 2421 for clamping the shell groove 1412, so that when the wiring harness connector is electrically connected to the electrical connection module 14, the electrical connection module 14 can be prevented from being displaced, thereby ensuring the connection effect between the wiring harness connector and the electrical connection module 14.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
