[0018] The effect achieved by the above components is: by setting the ball bearing to rotate with the screwdriver, the friction between the screwdriver and the rectangular plate is reduced, making it easier for the screwdriver to rotate or move.

[0019] In summary, the beneficial effects of this utility model are as follows: When the screwdriver is inserted into the pre-drilled hole of the protective cover, it presses against the guide groove of the rectangular plate. The two rectangular plates move away from each other, the spring on the pad deforms, and a gap is formed between the two rectangular plates. The screwdriver passes through the gap between the two rectangular plates and rotates the bolt. After the operator removes the screwdriver, the two rectangular plates move closer together under the action of the spring's return force, and finally the two rectangular plates stick together, achieving the effect of covering the pre-drilled hole. The two rectangular plates set by the protective device effectively cover the pre-drilled hole on the protective cover, preventing foreign objects from entering the inside of the terminal block through the pre-drilled hole and thus avoiding the possibility of an increased electric shock accident.

[0022] Reference Figure 1-6As shown, this embodiment discloses a terminal block with a covered head, including a base 1, which is detachably installed inside a mechanical device and provides overall support. Several square nuts are installed inside the base 1; conductive plates 2 are installed inside the base 1 and can transmit current; bolts 3 are located inside the base 1 and can fix cables using the square nuts; a protective cover 4 is detachably installed on one side of the base 1, and the protective cover 4 has a pre-drilled hole 5 corresponding to the bolt 3 (the pre-drilled hole 5 can be circular, rectangular, or elliptical). When the terminal block needs to be used, the operator moves the cable, with one end of the cable above the conductive plate 2. Then, the operator uses a screwdriver through the pre-drilled hole 5 of the protective cover 4 and rotates the bolt 3. The square nuts increase the torque between the bolt and the base 1, facilitating the bolt 3 to fix the cable. The bolt 3 and the conductive plate 2 together compress the cable, achieving the effect of fixing the cable and completing the cable connection.

[0023] Reference Figure 1-6 As shown, the protective cover 4 is provided with a protective device 6 at the reserved hole 5. The protective device 6 includes two rectangular plates 63, which are slidably connected to the surface of the protective cover 4. The two rectangular plates 63 can cover the reserved hole 5 of the protective cover 4. A spring 62 is fixedly connected to one side of the rectangular plate 63, and a pad 61 is fixedly connected to the other end of the spring 62. The pad 61 is fixedly connected to the protective cover 4. A guide groove 64 is opened on one side of the rectangular plate 63. When the screwdriver is inserted into the pre-drilled hole 5 of the protective cover 4, the screwdriver presses against the guide groove 64 of the rectangular plate 63, and the two rectangular plates 63 move away from each other. The spring 62 on the pad 61 deforms, and a gap is formed between the two rectangular plates 63. The screwdriver passes through the gap between the two rectangular plates 63 and rotates the bolt 3. Afterwards, the operator removes the screwdriver. Under the action of the spring 62's return force, the two rectangular plates 63 move closer to each other and finally stick together, achieving the effect of covering the pre-drilled hole 5. The two rectangular plates 63 set by the protective device 6 achieve the effect of covering the pre-drilled hole 5 on the protective cover 4, preventing foreign objects from entering the inside of the terminal block through the pre-drilled hole 5 and exacerbating the electric shock accident.

[0024] Reference Figure 1-6As shown, a telescopic rod 68 is fixedly connected to one side of the pad 61, with one end of the telescopic rod 68 fixedly connected to the rectangular plate 63. The telescopic rod 68 restricts the movement direction of the rectangular plate 63, preventing it from wobbling. The guide groove 64 has a funnel-shaped cross-section, with its tip away from the pre-drilled hole 5. The funnel-shaped guide groove 64 facilitates guiding the screwdriver to the center of the pre-drilled hole 5, positioning the screwdriver directly above the bolt 3 for easy rotation. Two symmetrical side plates 65 are fixedly connected to one side of one of the rectangular plates 63, and a storage groove 66 is provided on the other rectangular plate 63 corresponding to the side plate 65, with the dimensions of the side plate 65 matching the dimensions of the storage groove 66. The two side plates 65 limit the screwdriver's movement, preventing it from tilting and ensuring it rotates perpendicularly onto the bolt 3.

[0025] Reference Figure 1-6 As shown, protective pads 69, which are rubber pads, are fixedly connected to the sides of the two rectangular plates 63 that are close to each other. The protective pads 69 protect the two rectangular plates 63 from collision and damage. Two ball bearings 67 are located inside the rectangular plates 63, directly below the storage slot 66. The ball bearings 67 rotate with the screwdriver, reducing friction between the screwdriver and the rectangular plates 63, thus facilitating the screwdriver's rotation and movement.

[0026] Working principle: When the terminal block needs to be used, the operator moves the cable, with one end of the cable positioned above the conductive plate 2. Then, the operator moves the screwdriver, inserting it into the pre-drilled hole 5 of the protective cover 4. The screwdriver presses against the guide groove 64 of the rectangular plate 63, guiding the screwdriver to the center of the pre-drilled hole 5. The two rectangular plates 63 move away from each other, causing the spring 62 on the pad 61 to deform, creating a gap between the two rectangular plates 63. The screwdriver passes through this gap, and the two side plates 65 on the rectangular plates 63 limit the screwdriver's movement. The screwdriver rotates with the ball bearings 67 of the rectangular plate 63, thereby reducing... The friction between the small screwdriver and the rectangular plate 63 causes the screwdriver to rotate the bolt 3. The bolt 3 and the conductive plate 2 together press the cable, achieving the effect of fixing the cable and completing the cable connection. Finally, the operator removes the screwdriver. Under the action of the spring 62's return force, the two rectangular plates 63 move closer to each other. Ultimately, the two rectangular plates 63 are attached together with the help of the protective pad 69, achieving the effect of covering the reserved hole 5. The two rectangular plates 63 set by the protective device 6 achieve the effect of covering the reserved hole 5 on the protective cover 4, preventing foreign objects from entering the inside of the terminal block through the reserved hole 5 and exacerbating the electric shock accident.
