Description

Technical Field

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

[0002] Wire harnesses are mainly used for electrical connections in electronic products, and are made by crimping or soldering cables and terminals together. After processing, wire harnesses need to undergo several tests, such as the appearance of the terminals and the connection strength between the terminals and cables, to determine whether the wire harness processing is qualified. Most current testing institutions are single-function, only able to test appearance or connection strength, which means that the entire testing process requires multiple testing institutions to cooperate, resulting in large equipment space occupation and the need to clamp wire harnesses back and forth, resulting in low overall testing efficiency. Utility Model Content

[0003] To address the technical problems in the prior art, this utility model provides a multifunctional inspection device for wire harnesses, including a clamp base and a visual inspection mechanism for inspecting the appearance of terminals. A terminal positioning mechanism for fixing terminals is mounted on the clamp base. The visual inspection mechanism is mounted on the clamp base and located at one end of the terminal positioning mechanism. The clamp base also includes a wire clamping mechanism, left and right terminal pressing mechanisms, and a thrust detection mechanism for fixing cables. The wire clamping mechanism is located at the end of the terminal positioning mechanism away from the visual inspection mechanism. The left and right terminal pressing mechanisms are located on both sides of the terminal positioning mechanism. Under the action of the left and right terminal pressing mechanisms, the terminals are in contact with the top of the clamp base. The thrust detection mechanism is mounted at the bottom of the clamp base and located between the left and right terminal pressing mechanisms and the wire clamping mechanism. Under the action of the thrust detection mechanism, the cables move away from the top of the clamp base.

[0004] Furthermore, the fixture base includes a fixed base plate, a fixed base, and multiple first fixed guide posts. The fixed base plate and the fixed base are spaced apart in a vertical direction. The fixed base is mounted above the fixed base plate via the multiple first fixed guide posts. The fixed base plate has a through mounting hole and two mounting slots, which are symmetrically distributed on both sides of the mounting hole. The terminal positioning mechanism is mounted in the mounting hole via a connecting plate, and the top of the terminal positioning mechanism extends out of the top of the fixed base. The left and right terminal pressing mechanisms are mounted on the fixed base plate, and the tops of the left and right terminal pressing mechanisms slide through the two mounting slots and extend out of the top of the fixed base. The fixed base plate has a connecting hole corresponding to the mounting hole. The top of the thrust detection mechanism slides through the connecting hole and the mounting hole and abuts against the cable.

[0005] Furthermore, the fixed base, the fixed base plate, and the connecting plate are each provided with a plurality of first positioning posts and first positioning holes, and the terminal positioning mechanism and the left and right pressing terminal mechanism are each provided with a plurality of second positioning holes and second positioning posts, wherein the first positioning posts and the first positioning holes are respectively matched with the second positioning holes and the second positioning posts.

[0006] Furthermore, the fixture base also includes two fixed pressure plates, which are fixedly installed on both sides of the fixed base. A limiting space is formed between the fixed pressure plates and the mounting groove, and the left and right pressure terminal mechanisms are slidably installed within the limiting space.

[0007] Furthermore, the terminal positioning mechanism includes a positioning block and a secondary positioning mechanism. The top of the positioning block is provided with a placement groove that mates with the terminal. Both the positioning block and the secondary positioning mechanism are bolted to the connecting plate. The two clamping ends of the secondary positioning mechanism are slidably connected to the two sides of the positioning block. The terminal is installed in the placement groove and is fixedly connected to the placement groove under the action of the two clamping ends.

[0008] Furthermore, the upper part of both sides of the positioning block is symmetrically provided with two limiting grooves that connect the placement slots, and the two clamping ends are slidably connected to the two limiting grooves respectively.

[0009] Beneficial effects:

[0010] 1. In this utility model, by setting up a visual inspection mechanism, a terminal positioning mechanism, a wire clamping mechanism, a left and right terminal pressing mechanism, and a thrust detection mechanism, the appearance and connection strength of the wire harness can be inspected simultaneously. Moreover, the integrated design makes the equipment occupy little space, and the inspection can be completed in one clamping, which improves the inspection efficiency. The specific working process is as follows: after the equipment is powered on, each mechanism is in the initial state. At this time, the thrust detection mechanism is in the descending state, the left and right terminal pressing mechanism is in the ascending state, the visual inspection mechanism is in the ascending state, and the terminal positioning mechanism and the wire clamping mechanism are both in the open state. When the equipment is started, the terminal positioning mechanism clamps the terminal, limiting its horizontal displacement. The vision inspection mechanism descends to inspect and judge the appearance of the terminal, including the presence of loose wires and surface color. After inspection, the vision inspection mechanism rises. If the judgment is NG, an alarm is triggered; if the judgment is OK, the next process is automatically initiated. When the vision inspection mechanism judges it as OK, the left and right terminal pressing mechanisms descend to press the terminal, limiting its vertical displacement. At the same time, the wire clamping mechanism clamps the cable, and the thrust detection mechanism rises to push the cable according to the set thrust. Simultaneously, the judgment result is output as OK or NG. If the set thrust cannot push the cable away, it is judged as OK; if the set thrust pushes the cable away, it is judged as NG. After the thrust detection mechanism outputs the result, all mechanisms automatically reset, waiting for the next round of inspection.

[0011] 2. In this utility model, the first positioning post and the first positioning hole, as well as the matching second positioning hole and the second positioning post, enable convenient and quick installation and fixing of various mechanisms, improving installation efficiency. At the same time, the foolproof design can avoid assembly errors and facilitate bolt connection without the need for multiple people to cooperate. The limiting space formed by the fixed pressure plate and the fixed base facilitates the installation of the left and right pressure terminal mechanisms while preventing them from falling out of the mounting groove during movement, ensuring their linear movement.

[0012] 3. In this utility model, the positioning block and secondary positioning mechanism facilitate the positioning and fixing of the terminal. Combined with the sliding connection between the two clamping ends and the two sides of the positioning block, it can meet the fixing of terminals of different sizes. The setting of the limiting groove can prevent the clamping ends from disengaging from the limiting groove. Attached Figure Description

[0030] This utility model provides a multifunctional detection device for wire harnesses, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the device includes a clamp base 1 and a visual inspection mechanism 2 for inspecting the appearance of terminals. A terminal positioning mechanism 3 for fixing terminals is mounted on the clamp base 1. The visual inspection mechanism 2 is mounted on the clamp base 1 and located at one end of the terminal positioning mechanism 3. The visual inspection mechanism 2 includes a camera, a lens, a light source, a mounting bracket, and a lifting and adjusting assembly. The mounting bracket is fixedly mounted on the clamp base 1. The camera is movably connected to the mounting bracket via the lifting and adjusting assembly. The lens is connected to the camera, and the light source is arranged around the lens directly below it. The lifting and adjusting assembly can adjust the lens's position (up, down, left, right) to ensure accurate inspection results. The clamp base 1 also includes a wire clamping mechanism 4, a left and right terminal pressing mechanism 5, and a thrust detection mechanism 6 for fixing cables. The wire clamping mechanism 4 is located at the end of the terminal positioning mechanism 3 furthest from the visual inspection mechanism 2. The left and right terminal pressing mechanisms 5 are located on both sides of the terminal positioning mechanism 3. The terminal is pressed against the top of the clamp base 1 by the left and right terminal pressing mechanisms 5. The thrust detection mechanism 6 is mounted on the clamp base 1. The base 1 is located at the bottom and between the left and right terminal pressing mechanisms 5 and the wire clamping mechanism 4. The cable moves away from the top of the clamp base 1 under the action of the thrust detection mechanism 6. The clamp base 1 includes a fixed base plate 11, a fixed base 12 and multiple first fixed guide posts 13. The fixed base plate 11 and the fixed base 12 are arranged at intervals in the vertical direction. The fixed base 12 is installed above the fixed base plate 11 through multiple first fixed guide posts 13. The fixed base 12 has a through mounting hole and two mounting slots. The two mounting slots are symmetrically distributed on both sides of the mounting hole. The terminal positioning mechanism 3 is installed in the mounting hole through the connecting plate 7, and the top of the terminal positioning mechanism 3 extends out of the top of the fixed base 12. The left and right terminal pressing mechanisms 5 are installed on the fixed base plate 11. The top of the left and right terminal pressing mechanisms 5 slides through the two mounting slots and extends out of the top of the fixed base 12. The fixed base plate 11 has a connecting hole corresponding to the mounting hole. The top of the thrust detection mechanism 6 slides through the connecting hole and the mounting hole and abuts against the cable.

[0031] In this embodiment, by setting up the visual inspection mechanism 2, the terminal positioning mechanism 3, the wire clamping mechanism 4, the left and right terminal pressing mechanism 5 and the thrust detection mechanism 6, the appearance and connection strength of the wire harness can be inspected simultaneously. Moreover, the integrated design makes the equipment occupy little space, and the inspection can be completed in one clamping, thus improving the inspection efficiency.

[0032] like Figures 1 to 4As shown, the specific working process is as follows: After the equipment is powered on, each mechanism is in its initial state. At this time, the thrust detection mechanism 6 is in a descending state, the left and right terminal pressing mechanism 5 is in an ascending state, the vision inspection mechanism 2 is in an ascending state, and the terminal positioning mechanism 3 and the wire clamping mechanism 4 are both in an open state. When the equipment starts, the terminal positioning mechanism 3 clamps the terminal, limiting the horizontal displacement of the terminal. The vision inspection mechanism 2 descends to inspect and judge the appearance of the terminal, including whether there are loose wires, surface color, etc. After inspection, the vision inspection mechanism 2 rises. If the judgment is NG, an alarm is triggered. If the judgment is OK, the next process is automatically performed. When the vision inspection mechanism 2 judges OK, the left and right terminal pressing mechanism 5 descends to press the terminal, limiting the vertical displacement of the terminal. At the same time, the wire clamping mechanism 4 clamps the cable. The thrust detection mechanism 6 rises and pushes the cable according to the set thrust. At the same time, the judgment result is output as OK or NG. If the set thrust cannot push the cable open, the judgment is OK. If the set thrust pushes the cable open, the judgment is NG. After the thrust detection mechanism 6 outputs the result, each mechanism automatically resets and waits for the next round of inspection.

[0033] In this utility model, preferably, such as Figure 1 , Figure 3 and Figure 4 As shown, the left and right terminal pressing mechanism 5 includes two pressing components symmetrically arranged on the left and right sides. The two pressing components are located on both sides of the terminal positioning mechanism 3. The pressing components include a lifting cylinder 51, a lifting slider 52, a telescopic cylinder 53, and left and right sliders 54. The lifting cylinder 51 is fixedly installed on the fixed base plate 11 through a cylinder pad 55. The telescopic end of the lifting cylinder 51 is fixedly connected to the lifting slider 52. The lifting slider 52 is slidably installed in the mounting groove, and its top extends out of the fixed base 12. The lifting slider 52 moves up and down under the drive of the lifting cylinder 51. The top of the lifting slider 52 has a horizontal first sliding groove 521. The left and right sliders 54 are slidably installed in the first sliding groove 521. This ensures the linear movement of the left and right sliders 54 and prevents them from detaching from the lifting slider 52. The telescopic cylinder 53 is fixedly installed on the fixed base 12, and the telescopic end of the telescopic cylinder 53 is fixedly connected to the left and right sliders 54 through the first adapter plate 56. The two left and right sliders 54 move towards each other or away from each other under the drive of the two telescopic cylinders 53. The ends of the two left and right sliders 54 that are close to each other extend into the mounting hole and are located above the terminal or retract into the fixed base 12. In specific use, firstly, the telescopic cylinder 53 drives the left and right sliders 54 to extend into the mounting hole, and then the lifting cylinder 51 drives the lifting slider 52 to move down, so that the two left and right sliders 54 respectively abut against the top sides of the terminal and tightly fix the terminal on the terminal positioning mechanism 3.

[0034] In this embodiment, the lifting cylinder 51, the lifting slider 52, the telescopic cylinder 53, and the left and right sliders 54 are arranged to facilitate the fixing or disassembly of the terminals, while ensuring the firmness of the clamping.

[0035] In this utility model, preferably, such as Figure 3 and Figure 4 As shown, the clamping assembly further includes a first guide cover plate 57, on which a guide groove 571 is provided. The first guide cover plate 57 is fixedly installed on the lifting slider 52 by screws. The first adapter plate 56 slides through the guide groove 571 and is fixedly connected to the left and right sliders 54. The clamping assembly further includes a height adjustment mechanism 58, which includes a fixing block 581, an adjusting sleeve 582, and an adjusting screw 583. The fixing block 581 is fixedly installed on the end of the lifting slider 52 near the top by screws. The bottom of the fixing block 581 contacts the top of the fixed base 12. The fixing block 581 has a vertical through hole. The adjusting sleeve 582 is fixedly installed in the through hole. The adjusting screw 583 is threadedly connected to the adjusting sleeve 582. Under the action of thread engagement, the bottom of the adjusting screw 583 extends out of the bottom of the fixing block 581 and abuts against the fixed base 12.

[0036] In this embodiment, the first guide cover plate 57 can limit the left and right sliders 54 to prevent them from disengaging from the first slide groove 521, and guide the first adapter plate 56 to further ensure the linear movement of the left and right sliders 54. The height adjustment mechanism 58, which includes a fixing block 581, an adjusting sleeve 582 and an adjusting screw 583, can adjust the height of the left and right sliders 54 relative to the fixed base 12 to meet the installation and fixing of terminals of different thicknesses.

[0037] In this utility model, preferably, such as Figure 1 , Figure 5 and Figure 6As shown, the thrust detection mechanism 6 includes a fixed plate 61, a motor assembly 62, a lead screw module 63, a sliding assembly 64, and a top wire block 65. The fixed plate 61 is fixedly mounted on the fixture base 1 by bolts. The motor assembly 62 is fixedly mounted on the fixed plate 61, and the output shaft of the motor assembly 62 is connected to the lead screw module 63 via a coupling 8. The motor assembly 62 includes a motor 621 and a reducer 622. The motor 621 and the reducer 622 are connected by a flange and fixedly mounted on the fixed plate 61. The output shaft of the motor 621 is connected to the output shaft of the reducer 622 and is connected to the lead screw module 63 via the coupling 8. The sliding assembly 64 is slidably connected to the fixed plate 61 and, on the lead screw module 65, the top wire block 65. Driven by the rod module 63 and the motor assembly 62, the screw module 63 reciprocates along its axial direction. The screw module 63 specifically includes two mounting blocks, a screw, and a rotating block. The two mounting blocks are spaced apart and mounted on the fixed plate 61. The screw is rotatably connected to the two mounting blocks via bearings. The two mounting blocks are located at the ends of the screw near both ends. The rotating block has an internal thread and engages with the external thread on the screw via the internal thread. The sliding assembly 64 is fixedly connected to the rotating block by screws. The top wire block 65 is connected to the end of the sliding assembly 64 by screws. The end of the top wire block 65 away from the sliding assembly 64 has an arc-shaped groove. The cable is placed in the arc-shaped groove. This design prevents the cable from detaching from the top wire block 65.

[0038] In this embodiment, by setting up the fixed plate 61, motor assembly 62, lead screw module 63, sliding assembly 64 and top wire block 65, the motor assembly 62 can drive the top wire block 65 to move up and down along the axis of the lead screw module 63, thereby applying force to the cable and facilitating the detection of the connection strength between the cable and the terminal.

[0039] In this utility model, preferably, such as Figure 1 , Figure 5 and Figure 6As shown, the thrust detection mechanism 6 also includes a pressure sensor 66, which is fixedly installed on the end of the sliding assembly 64 and located between the top wire block 65 and the sliding assembly 64. The side of the pressure sensor 66 away from the sliding assembly 64 contacts the top wire block 65. There is a gap between the top wire block 65 and the sliding assembly 64. Under the action of external force, the top wire block 65 will move closer to the sliding assembly 64, thereby squeezing the pressure sensor 66. Specifically, when the top wire block 65 abuts against the cable, the cable presses against the top wire block 66. The reaction force of the wire block 65 will cause the top wire block 65 to move downward, thereby squeezing the pressure sensor 66 and causing it to generate a reading. The reading of the pressure sensor 66 can accurately measure the actual thrust of the thrust detection mechanism 6 on the cable. During detection, the output force of the motor assembly 62 is adjusted so that the reading of the pressure sensor 66 is equal to the set thrust, thus ensuring the accuracy of the detection result. The sliding assembly 64 has a first fixing groove at its end, and the top wire block 65 has a second fixing groove. The pressure sensor 66 is installed in the first fixing groove and the second fixing groove.

[0040] In this embodiment, the pressure sensor 66 enables accurate measurement of the actual thrust applied to the cable by the thrust detection mechanism 6, thereby ensuring the accuracy of the connection strength detection. The first and second fixing slots facilitate the installation and fixation of the pressure sensor 66, preventing its displacement. Furthermore, they ensure that the pressure sensor 66 is not damaged by excessive thrust while detecting the thrust. Specifically, since the fixing structure of the pressure sensor 66 is located within the first and second fixing slots, when an external force exceeding the pressure sensor 66's capacity occurs, the ends of the top wire block 65 and the sliding assembly 64 will form a hard limit to protect the pressure sensor 66.

[0041] In this utility model, preferably, such as Figure 1 , Figure 5 and Figure 6 As shown, the thrust detection mechanism 6 also includes a photoelectric sensor 67, which is fixedly installed on the fixed plate 61 and located on one side of the lead screw. The photoelectric sensor 67 includes two first sensing blocks spaced apart. A second sensing block is fixedly installed on the side of the sliding assembly 64. The second sensing block slides with the sliding assembly 64. When the second sensing block contacts the first sensing block, the motor assembly 62 stops rotating, thereby limiting the displacement of the top wire block 65 and preventing damage to the wiring harness and the thrust detection mechanism 6.

[0042] In this embodiment, the displacement of the top wire block 65 can be limited by the photoelectric sensor 67, thus preventing damage to the wire harness and the thrust detection mechanism 6 due to excessive displacement.

[0043] In this utility model, preferably, such as Figure 5 and Figure 6 As shown, the sliding assembly 64 includes an adjusting block group 641, a second adapter plate 642, and a guide rail 643. The adjusting block group 641 is fixedly connected to the rotating block by screws. The guide rail 643 is fixedly installed on the fixing plate 61 and located on the other side of the lead screw. A guide block is slidably installed on the guide rail 643. The guide block is fixedly connected to the adjusting block group 641 through the second adapter plate 642. The adjusting block group 641 includes a first movable block and a second movable block. The first movable block is fixedly connected to the rotating block by screws. One side of the first movable block is fixedly connected to the second adapter plate 642 by screws, and the other side is fixedly connected to the second sensing block by screws. The top of the first movable block is provided with a groove perpendicular to the axis of the lead screw. The second movable block is slidably installed in the groove and locked by screws. The second movable block slides relatively closer to or further away from the second adapter plate 642 along the direction of the groove.

[0044] In this embodiment, by adjusting the block group 641, the second adapter plate 642 and the guide rail 643, the top wire block 65 can be ensured to slide linearly; by adjusting the first movable block, the second movable block and the sliding connection between the two, the offset distance of the first movable block relative to the lead screw axis can be appropriately adjusted, thereby ensuring the smooth sliding of the guide block and the guide rail 643, and also ensuring the effective contact between the second sensing block and the first sensing block.

[0045] In this utility model, preferably, such as Figure 1 , Figure 7 and Figure 8As shown, the wire clamping mechanism 4 includes a mounting plate 41, two opposing wire clamping blocks 42, two third adapter plates 43, a transmission assembly 44, and a connecting cylinder 45. The mounting plate 41 is fixedly connected to the end of the fixed base 12 away from the visual inspection mechanism 2 via a fixed support plate 46 and a fixed adapter plate 47. The wire clamping blocks 42 are slidably connected to the top of the mounting plate 41 via the third adapter plates 43. A clamping space for clamping cables is formed between the two wire clamping blocks 42. Each opposing side of the wire clamping blocks 42 is provided with a flexible rubber layer 9. The flexible rubber layer 9 can protect the cable and prevent damage to the outer sheath. The connecting cylinder 45 is fixedly connected to the bottom of the mounting plate 41 via multiple second fixed guide posts 48. The telescopic end of the connecting cylinder 45 is connected to the two third adapter plates 43 via the transmission assembly 44. The two third adapter plates 43 are connected to the connecting cylinder 45. Driven by the transmission assembly 44, the wires slide towards or away from each other. The transmission assembly 44 includes a connecting column 441, a wire clamping push block 442, and two wire clamping sliders 443. The telescopic end of the connecting cylinder 45 is connected to the wire clamping push block 442 through the connecting column 441. The wire clamping push block 442 has symmetrically inclined T-shaped grooves on both sides. The top of the mounting plate 41 has a second groove. The two wire clamping sliders 443 are arranged opposite each other and are slidably installed in the second groove. The opposite side of the two wire clamping sliders 443 is provided with an inclined T-shaped slider, and the inclination direction of the T-shaped slider is the same as the inclination direction of the T-shaped groove. The two T-shaped sliders are slidably installed in the two T-shaped grooves. The two wire clamping sliders 443 clamp or open the cable under the action of the wire clamping push block 442 and the connecting cylinder 45. The top width of the wire clamping push block 442 is greater than the bottom width.

[0046] In this embodiment, the mounting plate 41, two opposing wire clamping blocks 42, two third adapter plates 43, a transmission assembly 44, and a connecting cylinder 45 enable rapid clamping and opening of the cable, facilitating cable fixation and disassembly. The connecting post 441, wire clamping push block 442, two wire clamping sliders 443, and T-shaped grooves and sliders allow the connecting cylinder 45 to extend and retract, driving the two wire clamping sliders 443 to slide left and right to clamp and open the cable. This allows for easy adjustment of the clamping force, ensuring a secure clamping, and accommodates cables of different sizes. Furthermore, it features a self-locking function; when the connecting cylinder 45 is de-energized, the two wire clamping sliders 443 remain in a fixed position and do not slide freely. The wire clamping push block 442's top width is greater than its bottom width, ensuring that the connecting cylinder 45 is in a clamping state when extended upwards and in an open state when retracted, significantly increasing the upper limit of the clamping force and further ensuring a secure clamping.

[0047] In this utility model, preferably, such as Figure 1 , Figure 7 and Figure 8 As shown, the wire clamping mechanism 4 also includes four second guide covers 49, which are symmetrically installed on the top of the mounting plate 41 and located above the wire clamping slider 443. Two second guide covers 49 on the same side are spaced apart. The third adapter plate 43 is slidably installed on the top of the two second guide covers 49 and extends from between the two guide plates to be fixedly connected to the wire clamping slider 443. The wire clamping mechanism 4 also includes a dust cover 49a, which is fixedly installed on the top of the mounting plate 41 and located between the four second guide covers 49. The top of the dust cover 49a is flush with the top of the third adapter plate 43. This arrangement can appropriately limit the sliding of the two wire clamping blocks 42 to prevent damage to the cable due to excessive clamping force.

[0048] In this embodiment, the four second guide covers 49 can slide and limit the third adapter plate 43, ensuring that the wire clamping slider 443 slides horizontally and linearly along the second slide groove; the dust cover 49a can prevent dust and debris from entering the second slide groove, ensuring that the wire clamping slider 443 slides smoothly.

[0049] In this utility model, preferably, such as Figures 1 to 4 As shown, the fixed base 12, the fixed base plate 11 and the connecting plate 7 are each provided with a plurality of first positioning posts and first positioning holes, and the terminal positioning mechanism 3 and the left and right pressing terminal mechanism 5 are each provided with a plurality of second positioning holes and second positioning posts. The first positioning posts and the first positioning holes are respectively matched with the second positioning holes and the second positioning posts.

[0050] In this embodiment, the first positioning post and the first positioning hole, as well as the matching second positioning hole and the second positioning post, enable convenient and quick installation and fixing of various mechanisms, improving installation efficiency. At the same time, the foolproof design can prevent assembly errors, and bolt connections can be easily made without the need for multiple people to cooperate.

[0051] In this utility model, preferably, such as Figure 1 , Figure 3 and Figure 4 As shown, the clamp base 1 also includes two fixed pressure plates 14, which are fixedly installed on both sides of the fixed base 12. A limiting space is formed between the fixed pressure plates 14 and the mounting groove, and the left and right pressure terminal mechanisms 5 are slidably installed in the limiting space.

[0052] In this embodiment, by setting the limiting space formed by the fixed pressure plate 14 and the fixed base 12, it is possible to facilitate the installation of the left and right pressure terminal mechanisms 5 while preventing them from falling out of the mounting groove during movement, thus ensuring their linear movement.

[0053] In this utility model, preferably, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the terminal positioning mechanism 3 includes a positioning block 31 and a secondary positioning mechanism 32. The top of the positioning block 31 is provided with a placement groove that cooperates with the terminal. The positioning block 31 and the secondary positioning mechanism 32 are both installed on the connecting plate 7 by bolts. The two clamping ends of the secondary positioning mechanism 32 are slidably connected to the two sides of the positioning block 31. The terminal is installed in the placement groove and is fixedly connected to the placement groove under the action of the two clamping ends. The upper part of both sides of the positioning block 31 is symmetrically provided with two limiting grooves that communicate with the placement groove. The two clamping ends are slidably connected to the two limiting grooves respectively.

[0054] In this embodiment, the positioning block 31 and the secondary positioning mechanism 32 facilitate the positioning and fixing of the terminal. The two clamping ends are slidably connected to both sides of the positioning block 31, which can meet the fixing of terminals of different sizes. The setting of the limiting groove can prevent the clamping ends from disengaging from the limiting groove.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
