[0002] Terminal blocks are key components in electrical equipment used to connect cables to internal circuits, and are widely used in various electronic, power, and communication devices. Terminal blocks typically consist of a plastic housing, a conductor, and fastening screws for securing the cable connection.

[0003] In existing technologies, to facilitate the use of tools to tighten the fastening screws, the fastening screws and conductive pins of terminal blocks are usually exposed. However, because terminal blocks are exposed to the external environment for extended periods, dust, insects, and debris can fall into the terminal blocks, leading to poor dust protection, poor contact, and consequently affecting circuit stability and even causing electrical faults. Furthermore, the exposed screws and conductive metal parts may pose a risk of electric shock to users or operators. To improve dust protection, existing technologies often hinge dust covers to the housing. However, rotating the dust cover requires more space to open and close, which can be limiting due to space constraints. Utility Model Content

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0040] Example 1:

[0041] This embodiment provides a universal terminal block, including:

[0042] The outer casing 1 has a mounting port 6 on one side in the Z-axis direction and first wiring holes 7 on both sides in the X-axis direction.

[0043] Cover plate 2 is provided on the mounting port 6. A sliding groove 8 is provided on the inner side of cover plate 2. Multiple strip holes 9 are also provided on cover plate 2. Multiple through holes 10 are also provided on cover plate 2.

[0044] Conductor 3 is disposed inside housing 1. Conductor 3 is provided with a second wiring hole 11. The first wiring hole 7 is directly opposite the second wiring hole 11. One side of the conductor 3 along the Z-axis is provided with a plurality of threaded holes 12 connected to the second wiring hole 11. The threaded holes 12 are directly opposite the through hole 10.

[0045] Multiple fastening screws 4 are threaded onto threaded holes 12;

[0046] Dust cover 5 is slidably mounted on slide groove 8. Push rod 13 is provided on the outside of dust cover 5. Push rod 13 passes through strip hole 9 and extends to the outside of cover plate 2.

[0047] The through hole 10 is located on the sliding path of the dust cover 5, and the dust cover 5 is used to open and close the through hole 10.

[0048] In this technical solution, the outer casing 1 can be made of plastic, such as PVC, PE, and PP, and the plastic casing can serve as insulation. The outer casing 1 has a receiving groove for mounting the conductor 3, and the mounting port 6 of the outer casing 1 communicates with the receiving groove.

[0049] A base can be provided on the side of the outer casing 1 away from the mounting port 6. The base is used to mount the outer casing 1 on the fixed surface. The base can be provided with screw holes for mounting screws, or it can be provided with slots for mounting on a guide rail.

[0050] The conductor 3 can be a conductive metal, such as aluminum, which has excellent conductivity. The conductor 3 passes through the mounting port 6 and is installed into the receiving groove. The conductor 3 can also pass through a second wiring hole 11, which is directly opposite the first wiring hole 7, along the X-axis, with the end of the wire inserted into the second wiring hole 11.

[0051] A hexagonal groove can be formed on the fastening screw 4. By using a tool to pass through the through hole 10 on the cover plate 2 and insert it into the hexagonal groove, the fastening screw 4 can be rotated, for example, by turning the fastening screw 4 with a screwdriver, thereby fixing the end of the wire into the second wiring hole 11 and realizing circuit conduction. The wire can be removed by turning the fastening screw 4 in the opposite direction.

[0052] There can be two first wiring holes 7, and one second wiring hole 11 that passes through the conductor 3 (not shown in the figure). There can be two fastening screws 4. The number of through holes 10 and the number of dust covers 5 correspond to the number of fastening screws 4. The two fastening screws 4 fasten the ends of the two wires respectively.

[0053] The cover plate 2 is also made of plastic. The diameter of the through hole 10 on the cover plate 2 is smaller than the diameter of the fastening screw 4 to prevent excessive tightening that could cause the fastening screw 4 to come out. The strip hole 9 can be set along the X-axis. By pushing the push rod 13 with a finger, the push rod 13 moves within the strip hole 9, thereby allowing the dust cover 5 to slide within the groove 8 on the inner side of the cover plate 2. When it is necessary to insert a tool into the through hole 10 to tighten the fastening screw 4, push the dust cover 5 to keep the through hole 10 open. After wiring or disconnection is completed, push the dust cover 5 in the opposite direction to keep the through hole 10 closed, preventing dust, insects, and debris from falling onto the conductor 3 and the fastening screw 4, thus achieving a dustproof effect.

[0054] In summary, by pushing the push rod 13, the dust cover 5 slides inside the cover plate 2, and the through hole 10 on the cover plate 2 is closed to prevent dust from entering the outer casing 1. Pushing the push rod 13 in the opposite direction opens the through hole 10 on the cover plate 2, which facilitates wiring. This achieves quick and convenient operation when opening and closing, a compact structure, small space occupation, and the dust cover 5 is not easy to fall off or be lost.

[0055] Furthermore, the dust cover 5 is provided with a clearance notch 32 for avoiding the through hole 10. Inclined surfaces 34 are provided on both sides of the clearance notch 32 on the dust cover 5. Multiple sliders 33 are symmetrically arranged at the bottom of the cover plate 2. A sliding groove 8 is formed between the cover plate 2 and the multiple sliders 33. Inclined surfaces 34 are also provided around the sliders 33.

[0056] In this technical solution, such as Figure 2-4 As shown, symmetrical reinforcing ribs are provided on the inner side of the cover plate 2 to improve the structural strength of the cover plate 2. The slider 33 can be set on the reinforcing ribs, the slide groove 8 is formed between the slider 33 and the cover plate 2, and the dust cover 5 is inserted into the slide groove 8 and can slide within the slide groove 8.

[0057] An inclined surface 34 is provided on both sides of the slider 33 and the clearance notch 32 to allow the dust cover 5 to be pushed smoothly and avoid jamming.

[0058] The dust cover 5 can be a thin sheet structure with flexibility. When the dust cover 5 is inserted into the groove 8 from one side of the cover plate 2 in the X-axis direction, the push rod 13 can be installed into the strip hole 9 without interference.
