Description

Technical Field

[0001] This invention relates to the field of wire harness connector testing technology, and more specifically, to a modular and reconfigurable wire harness connector testing platform. Background Technology

[0002] A wire harness connector is a type of terminal. A connector, also known as a plug, consists of a plug and a socket. Connectors are relay stations for wire harnesses in a circuit. They are generally used for connections between wire harnesses and between wire harnesses and electrical components.

[0003] For example, CN105182098A discloses a universal test fixture for testing wire harnesses, including an installation and operation platform. The platform includes several test circuit boards for wire harnesses of different specifications. The circuits on the test circuit boards are identical. Corresponding mating connectors are integrated on the test circuit boards for the connectors at one end of the wire harnesses of different specifications. Two slide rails are arranged side by side on the installation and operation platform. A fault-proofing test device that mates with the plug-in connector at the other end of the wire harness under test is located at one end of the two slide rails. The test circuit boards are located between the two slide rails. The test circuit boards and the fault-proofing test device are electrically connected to a test machine for electrical testing of the wire harness under test. The fault-proofing test device includes a base with a row of pins that can meet the mating requirements of plug-in connectors of different specifications.

[0004] There are various specifications of wire harness connectors, and the test fixture mentioned above is equipped with a dedicated test circuit board for each different specification of wire harness. The problem is that only one circuit board is activated and used during testing, while the rest are idle. The utilization rate of the modules is low, and the same functional circuits are repeatedly manufactured, which doubles the material cost. Summary of the Invention

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

[0006] The purpose of this invention is to provide a modular reconfigurable wire harness connector testing platform. By setting multiple pins and sockets, different numbers and shapes of pins or sockets can be spliced ​​and combined to form a structure corresponding to the specifications of the wire harness connector, thereby improving the utilization rate of the module.

[0007] To achieve the above objectives, the present invention aims to provide a modular reconfigurable wire harness connector testing platform, including a testing host and an electrical connection device, wherein the electrical connection device includes a base and a reconfigurable body disposed on the base;

[0008] The base includes a base plate, a vertical plate, and an electrical connection module for mating wire harness connector plugs or sockets. The electrical connection module is also electrically connected to the test host.

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

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

[0011] As a further improvement to this technical solution, the electrical connection module includes multiple component housings and conductive components disposed within the component housings. The conductive components are pins or sockets that match the pins or sockets of the wire harness connector. The conductive components are electrically connected to the test host via wires. Two adjacent sides of the component housings are provided with second locking blocks, and the other two adjacent sides are provided with corresponding locking slots. The second locking blocks and locking slots are inserted and engaged.

[0012] Furthermore, the base also includes a placement rack fixedly installed on both sides of the upright plate, which is used to store component housings.

[0013] According to the specifications of the wire harness connector to be tested, remove the corresponding number of component housings from the placement rack, and make sure that the conductive parts match the pins or sockets of the wire harness connector. Then, arrange and combine multiple component housings according to the pin or socket positions of the wire harness connector. The corresponding second card block is inserted into the card slot of the adjacent component housing for pre-assembly, thereby obtaining an electrical connection module that matches the specifications of the wire harness connector.

[0014] As a further improvement to this technical solution, the upright plate is an "O"-shaped structural plate that is inserted and matched with the base platform at the bottom. The upright plate has plate grooves on the left and right sides. The placement frame includes a slide body and multiple grid plates that are equally spaced on the surface of the slide body. The spacing between adjacent grid 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 locking block is provided on the contact surface between the grid plate and the component shell, and the first locking block engages with the shell groove.

[0016] The component housing is secured within the space formed by adjacent grid panels to prevent accidental detachment of the component housing.

[0017] As a further improvement to this technical solution, the adjustment structure includes an adjustment knob and a first transmission rod meshing with the bottom end of the adjustment knob. The top end 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. The pre-pressing structure includes two first movable plates and a pre-pressing plate disposed on the side of the first movable plate near the adjustment knob. The two first movable plates are horizontally symmetrically disposed on the inner wall of the vertical plate and are horizontally slidably connected to the inner wall of the vertical plate. The first transmission rod is threadedly connected to the first movable plate. The pre-pressing plate is used to contact the electrical connection module.

[0018] Furthermore, the contact surface between the pre-pressure plate and the electrical connection module is provided with a soft pad to increase friction. Rotating the adjustment knob causes the adjustment knob to drive the first transmission rod to rotate. The rotation of the first transmission rod then drives the first movable plate to slide horizontally along the inner wall of the vertical plate towards the electrical connection module until the pre-pressure plates of the two first movable plates contact and clamp the electrical connection module. After that, the hand holding the electrical connection module is released, and the pre-pressure plate ensures friction with the electrical connection module through the soft pad.

[0019] As a further improvement to this 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 engages with the end of the first transmission rod away from the adjustment knob. The two ends of the second movable plates are vertically slidably connected to the inner wall of the vertical plate.

[0020] As the adjustment knob is rotated, causing the first transmission rod to drive the first movable plate to slide horizontally along the inner wall of the vertical plate towards the electrical connection module, the first transmission rod simultaneously drives the second transmission rod to rotate. The second transmission rod then drives the two second movable plates to slide vertically along the inner wall of the vertical plate towards the electrical connection module. When the two pre-pressure 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 to this technical solution, a limiting rod is provided on the back side of the pre-pressure plate. One end of the limiting rod passes through the first movable plate and engages with it. A limiting spring is sleeved on the surface of the limiting rod. The pre-pressure plate is elastically connected to the first movable plate through the limiting spring. When the pre-pressure plate contacts the electrical connection module, the limiting rod can still slide horizontally, thereby facilitating the movement of the second movable plate to contact and fix the electrical connection module.

[0022] As a further improvement to this technical solution, the contact surface between the second movable plate and the electrical connection module is provided with a limiting groove for locking the housing groove, so as to prevent the electrical connection module from shifting.

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

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

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

[0026] 2. In this modular reconfigurable wire harness connector test platform, when the adjustment knob is rotated to cause the first transmission rod to drive the first movable plate to slide horizontally along the inner wall of the vertical plate towards the electrical connection module, the first transmission rod simultaneously drives the second transmission rod to rotate. The second transmission rod then drives the two second movable plates to slide vertically along the inner wall of the vertical plate towards the electrical connection module. When the two pre-pressure 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, the electrical connection module can be pressed together, squeezing multiple component shells into a stable whole, thereby avoiding the situation where one or more component shells become loose when connecting the wire harness connector.

Therefore, they should not be construed as limitations on this invention.

[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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] Please see Figure 1 , Figure 2 , Figure 6 As shown, the purpose of this embodiment is to provide a modular reconfigurable wire harness connector test platform, including a test host and an electrical connection device. The electrical connection device includes a base 1 and a reconfigurable body 2 disposed on the base 1.

[0043] The base 1 includes a base 11, a vertical plate 12, and an electrical connection module 14 for mating wire harness connector plugs or sockets. The electrical connection module 14 is also electrically connected to the test host.

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

[0045] After setting the electrical connection module 14 according to the specifications of the wire harness connector plug or socket (number and shape of plug or socket), the electrical connection module 14 is lifted and placed inside the upright plate 12. The adjustment structure is rotated, and the adjustment structure drives the pre-pressing structure 23 to slide horizontally from both sides to the middle along the inner wall of the upright plate 12. At the same time, the adjustment structure drives the pressing structure 24 to slide vertically from both sides to the middle along the inner wall of the upright 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, the wire harness connector is aligned with the electrical connection module 14 so that the pins or sockets of the wire harness connector are electrically connected to the electrical connection module 14. Finally, the test host performs performance testing on the wire harness connector.

[0046] The above structure is disclosed below:

[0047] Considering the different specifications of various wire harness connectors, namely the different numbers and shapes of pins or sockets, it is necessary to match the wire harness connectors to be tested before performance testing. Figure 2 , Figure 3 , Figure 4As shown, the electrical connection module 14 includes multiple component housings 141 and conductive elements 142 disposed within the component housings 141. The conductive elements 142 are pins or sockets that match the pins or sockets of the wire harness connector. The conductive elements 142 are electrically connected to the test host via wires. Two adjacent surfaces of the four surfaces of the component housings 141 are provided with second locking blocks 1411, and the other two adjacent surfaces of the four surfaces of the component housings 141 are correspondingly provided with locking slots. The second locking blocks 1411 are inserted and engaged with the locking slots. Furthermore, the base 1 also includes a placement rack 13 fixedly disposed on both sides of the upright plate 12. The placement rack 13 is used to store the component housings 141. According to the specifications of the wire harness connector to be tested, a corresponding number are removed from the placement rack 13. Furthermore, the conductive component 142 is matched with the pins or sockets of the wire harness connector. Then, multiple component shells 141 are arranged and combined according to the pin or socket positions of the wire harness connector. The corresponding second locking block 1411 is inserted into the slot of the adjacent component shell 141 for pre-assembly, thereby obtaining an electrical connection module 14 that matches the specifications of the wire harness connector. The advantage of the electrical connection module 14 obtained by this reconstruction method is that when testing different wire harness connectors, it is only necessary to select the corresponding component shell 141 according to the specifications of the wire harness connector and arrange the component shells 141 accordingly to obtain the electrical connection module 14 that matches the wire 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 upright plate 12 is an "O"-shaped structural plate that is inserted and fitted into the base platform 11 at the bottom. The upright plate 12 has grooves 121 on both its left and right sides. The placement rack 13 includes a slider body and multiple grating plates 131 evenly spaced on the surface of the slider body. The spacing between adjacent grating plates 131 matches the thickness of the component shell 141. Furthermore, a shell groove 1412 is formed in the center of the surface of the component shell 141. Correspondingly, a first locking block 132 is provided on the contact surface between the grating plate 131 and the component shell 141. The first locking block 132 engages with the shell... The slot 1412 engages with the component housing 141. Under normal circumstances, the component housing 141 is temporarily stored in the gap between the adjacent grid plates 131. When the component housing 141 is needed, it can be removed from the gap between the adjacent grid plates 131. The purpose of setting the first locking block 132 and the housing slot 1412 is to lock the component housing 141 in the space formed by the adjacent grid plates 131 while ensuring that the component housing 141 can move, so as to avoid the component housing 141 from accidentally falling off, and also to facilitate the management of multiple component housings 141.

[0049] After configuring the electrical connection module 14 to match the wire harness connector specifications, it is necessary to press the electrical connection module 14 together to ensure that the multiple component housings 141 within the electrical connection module 14 form a stable whole. This prevents the component housings 141 from becoming loose when the pins or sockets of the electrical connection module 14 contact the wire harness connector. Figure 6 , Figure 7 As shown, the adjustment structure includes an adjustment knob 21 and a first transmission rod 22 meshing 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 disposed on the side of the first movable plate 231 near the adjustment knob 21. The two first movable plates 231 are horizontally symmetrically disposed 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... The end passes through the first movable plate 231 and is threadedly connected to it. The pre-pressure plate 232 is used to contact the electrical connection module 14. The contact surface between the pre-pressure plate 232 and the electrical connection module 14 is provided with a soft pad to increase friction. With one hand, place the set electrical connection module 14 in the center of the "O"-shaped area of ​​the upright plate 12, and then with the other hand, turn the adjustment knob 21. This causes the adjustment knob 21 to drive the first transmission rod 22 to rotate. The rotation of the first transmission rod 22 then drives the first movable plate 231 to slide horizontally along the inner wall of the upright plate 12 toward the electrical connection module 14. Figure 9 As shown by the middle arrow a, after the pre-pressure plates 232 of the two first movable plates 231 contact and clamp the electrical connection module 14, the hand holding the electrical connection module 14 is released. The pre-pressure plates 232 ensure friction on the electrical connection module 14 through the set soft pads to prevent the electrical connection module 14 from sliding.

[0050] During the process of the first movable plate 231 sliding and clamping the electrical connection module 14, as described above, 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 upright plate 12, and the top end of the second transmission rod 241 engages with the end of the first transmission rod 22 away from the adjusting knob 21. The two ends of the second movable plates 242 are vertically slidably connected to the inner wall of the upright plate 12. When the adjusting knob 21 is rotated, causing the first transmission rod 22 to drive the first movable plate 231 to slide horizontally along the inner wall of the upright plate 12 toward the electrical connection module 14, the first transmission rod 22 simultaneously drives the second transmission rod 241 to rotate. The second transmission rod 241 then drives the two second movable plates 242 to slide vertically along the inner wall of the upright plate 12 toward the electrical connection module 14, as shown. Figure 9As shown by the middle arrow b, when the two pre-pressure 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 the lateral and longitudinal directions, the electrical connection module 14 can be pressed together, and multiple component shells 141 are squeezed into a stable whole, thereby avoiding the loosening of one or more component shells 141 when connecting the wire harness connector.

[0051] It is worth noting that, in addition to the differences in the number and shape of pins or sockets, different wire harness connectors also differ in port shape. When testing a wire harness connector with a flat port shape, such as an HDMI cable interface, during the fixing of the electrical connection module 14 with the corresponding flat shape, a situation may occur where the preload plate 232 has already 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-pressure plate 232. One end of the limiting rod 233 passes through the first movable plate 231 and engages with it. A limiting spring 234 is sleeved on the surface of the limiting rod 233. The pre-pressure plate 232 is elastically connected to the first movable plate 231 through the limiting spring 234. By setting the elastic connection, the first movable plate 231 obtains a certain amount of movement space. That is, when fixing the flat and elongated electrical connection module 14, even when the pre-pressure plate 232 contacts the electrical connection module 14, the limiting rod 233 can still slide horizontally, which facilitates the movement of the second movable plate 242 to contact and fix the electrical connection module 14. Furthermore, the contact surface between the second movable plate 242 and the electrical connection module 14 is provided with a limiting groove 2421 for locking the housing groove 1412. Thus, when the wire harness connector is electrically connected to the electrical connection module 14, displacement of the electrical connection module 14 can be avoided, ensuring the connection effect between the wire harness connector and the electrical connection module 14.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
