[0002] Terminal blocks usually refer to connector components used to connect wires, cables or other devices in electronic or electrical equipment. Their main function is to provide a safe and reliable electrical connection.

[0003] Since exposed terminals are easily accumulated with dirt or invaded by liquid, thus affecting the stability and reliability of the electrical connection, and terminals are susceptible to mechanical damage or collision with external objects, resulting in poor contact or even short circuit, protective covers can usually be used to effectively protect the terminals.

[0004] The protective cover needs to be set up to facilitate the staff to carry out circuit maintenance on the internal wiring terminals. A flip-up design can be adopted. When maintenance is needed, the cover plate on the protective cover is flipped open; after the maintenance work is completed, the cover plate is closed. After the cover plate is closed, it needs to be further locked to prevent the cover plate from accidentally opening due to gravity or other factors. If the cover plate is accidentally opened, the internal wiring terminals will be contaminated by dust or moisture, affecting the stability of the circuit.

[0005] Therefore, in order to solve the above technical problems, we propose a terminal protection device. Utility Model Content

[0040] Among them, Figure 1 As shown, the slide groove 101a-3 is configured to be arc-shaped.

[0041] Preferably, a limiting groove 101a-31 is provided at the end of the sliding groove 101a-3, and a limiting ring 202b-1 is provided at one end of the sliding shaft 202b.

[0042] Preferably, the locking member 203 includes a handle 203a movably disposed outside the cover body 101a.

[0043] Preferably, a convex ring 203a-1 is provided on the outer wall of the handle 203a, and the convex ring 203a-1 is movably matched with the limiting groove 101a-31.

[0044] Preferably, a slider 203a - 2 is provided on the outer wall of the handle 203a , and the slider 203a - 2 is movably matched with the sliding shaft 202b .

[0045] The setting of the handle 203a can facilitate the pulling operation of the staff; when the staff needs to inspect the terminal J inside the cover body 101a, the handle 203a can be pulled outward to make the convex ring 203a-1 disengage from the limit groove 101a-31, and the position lock of the cover plate 102a is released, and then the staff can pull the pull plate 102a-1 outward, and the guide member 202 moves in the slide groove 101a-3, thereby driving the second connecting rod 201b and the first connecting rod 201a to move, so that the cover plate 102a is unlocked. 02a is opened, and the staff can operate the internal wiring terminal J; after the operation is completed, the cover plate 102a can be pushed to close it. After the guide member 202 moves to the corresponding position in the slide groove 101a-3, the handle 203a is pushed, and the slider 203a-2 moves on the guide member 202, so that the convex ring 203a-1 is stuck in the limit groove 101a-31, thereby preventing the guide member 202 from moving and locking the guide member 202, thereby further fixing the position of the cover plate 102.

[0046] In summary, by setting the locking member 203, when the staff opens the cover plate 102a and completes the operation on the internal terminal J, the cover plate 102a can be closed. At this time, the sliding shaft 202b moves in the sliding groove 101a-3. When the guide member 202 moves to the corresponding position, the handle 203a is pressed to make the convex ring 203a-1 snap into the limiting groove 101a-31, thereby achieving further stabilization of the cover plate 102a after closing.
