Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Reference Figure 1-6As shown, a data acquisition card that is easy to wire and maintain includes a housing 1, a main board 2, a terminal board 3, a clamping device 4, a first top plate 5, a second top plate 6, an end cover 7, and a baffle 8. The first top plate 5 and the end cover 7 are mounted on the housing 1 with screws. A notch 701 is provided on the end cover 7 near the clamping device 4, which is provided for the wires to pass through the data acquisition card body and connect to the terminals on the terminal board 3.

[0027] Specifically, the left and right side panels of the outer casing 1 have slots 101, and the motherboard 2 is placed in the slots 101. The motherboard 2 can be installed into the acquisition card body by pulling it out.

[0028] Specifically, the motherboard 2 and terminal board 3 have a first through hole 51. A support post 9 is provided between the motherboard 2 and terminal board 3. The support post 9 has a threaded through hole. The motherboard 2 and terminal board 3 are fixedly connected to both ends of the support post 9 by screws, thereby fixing the motherboard 2 and terminal board 3 together. During the assembly of the acquisition card, the motherboard 2 is pushed into the acquisition card body along the card slot 101, thereby pushing the motherboard 2 and terminal board 3 into the acquisition card body together, which is convenient for installation.

[0029] Furthermore, in another embodiment, the support column 9 may be a double-through hexagonal copper column or a double-through nylon column. The number of support columns 9 shall not be less than four.

[0030] Specifically, the mounting post 10 is fixedly connected to the upper surface of the bottom plate of the outer casing 1. The upper part of the mounting post 10 has an internal thread, and the main board 2 has a second through hole 52. A single-through hexagonal stud 11 passes through the second through hole 52 and is threadedly connected to the mounting post 10. The height of the mounting post 10 is equal to the distance between the bottom of the slot 101 and the upper surface of the bottom of the outer casing 1, which does not affect the pushing of the main board 2 and the terminal board 3 into the body of the acquisition card along the slot.

[0031] Specifically, the clamping device 4 includes a lower clamping plate 41, an upper clamping plate 42, and a fastening rod 43. The lower clamping plate 41 has a third through hole 53. A screw passes through the third through hole 53 and is threadedly connected to a single-through hexagonal stud 11, thereby fixing the lower clamping plate 41 inside the outer casing 1.

[0032] Specifically, the upper clamping plate 42 is movably connected to a fastening rod 43, which includes an end 431, a sliding rod 432, and a threaded rod 433. The end 431 is fixedly connected to one end of the sliding rod 432, and the other end of the sliding rod 432 is fixedly connected to one end of the threaded rod 433. A spring 434 is fitted onto the sliding rod 432. The upper clamping plate 42 has a fourth through hole 54 through which the sliding rod 432 passes and is movably connected to the upper clamping plate 42. The spring 434 is located between the end 431 and the upper clamping plate 42 and is in a compressed state. The lower clamping plate 41 has a threaded through hole 55, and the threaded rod 433 is threadedly connected to the lower clamping plate 41.

[0033] When securing the wire, the wire passes between the upper clamping plate 42 and the lower clamping plate 41. Press the fastening rod 43 downwards so that its lower end enters the threaded through hole 55. Tighten the end 431 to screw the fastening rod into the threaded through hole 55. The upper clamping plate 42 moves further downwards until it contacts the wire. Continue tightening the fastening rod 43 downwards, further compressing the spring 434 and pressing the upper clamping plate 42 tightly against the lower clamping plate 41. The pressure between the upper and lower clamping plates 42 and 41 secures the wire. The end 431 has anti-slip textures for easy manual tightening of the fastening rod 43.

[0034] When disassembling the wire, tighten the fastening rod 43 upwards to increase the gap between the upper clamping plate 42 and the lower clamping plate 41, thus allowing the wire to be disassembled. Alternatively, tighten the fastening rod 43 upwards to separate the threaded rod 433 from the lower clamping plate 41. Since the diameter of the threaded rod 433 is larger than the diameter of the fourth through hole 55, the fastening rod 43 will not fall off the upper clamping plate 42, preventing parts from being lost.

[0035] Specifically, an elastic protective layer 44 is provided on the opposite side of the upper clamping plate 42 and the lower clamping plate 41 to protect the wire from being crushed when it is fixed.

[0036] Specifically, the second top plate 6 is provided with a raised edge 12, the upper surface of which mates with the lower surface of the first top plate 5. After the data acquisition card body is installed, the end of the first top plate 5 closest to the second top plate 6 will press against the raised edge 12. The raised edge 12 eliminates the gap between the first top plate 5 and the second top plate 6 during installation, thereby preventing dust and other contaminants from entering the data acquisition card. The raised edge 12 also serves to fix one end of the second top plate 6 to the first top plate 5.

[0037] Specifically, the second top plate 6 is located directly above the terminal board 3, and the baffle 8 is fixedly installed at one end of the terminal board 3, and the baffle 8 is located below the raised edge 12. When it is necessary to repair the terminals or replace the wiring, only the second top plate 6 needs to be removed, thus exposing only the terminal board 3. In conjunction with the baffle 8 located below the raised edge 12, the motherboard 2 is effectively prevented from being exposed, preventing accidental damage to the motherboard 2 or the entry of debris into the acquisition card during terminal repair or wiring operations.

[0038] Specifically, the second top plate 6 is installed on the top of the outer casing 1 by hand screws 13. The second top plate 6 can be removed by hand screws 13 without the need for tools, making the operation convenient.

[0039] Furthermore, in another embodiment, the hand-tightening screw 13 can be a non-detachable press-fit screw to prevent the screw from being lost after the second top plate 6 is removed, and the number of hand-tightening screws 13 is 2.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
