[0023] Example 1
[0024] like Figure 1-8As shown, this embodiment provides a contactor visual protection device, including an upper protective plate 1, a lower protective plate 3, and a visible protective plate 2; the visible protective plate 2 is made of polycarbonate material;
[0025] The contactor 7 is fixed on the first mounting plate 6, and its copper busbars are exposed and visible, posing a safety hazard. The upper protective plate 1 and the lower protective plate 3 are fixedly installed on the first mounting plate 6. The upper protective plate 1 and the lower protective plate 3 are respectively located around the energized copper busbars at the upper and lower ends of the contactor 7, preventing personnel from touching the energized copper busbars of the contactor 7 and also preventing materials from falling onto the contactor 7. One side of the visible protective plate 2 is inserted into the upper protective plate 1, and the other side is fixedly connected to the lower protective plate 3. Its overall structure protects the contactor 7.
[0026] The lower guard plate 3 and the visible guard plate 2 are connected to form an L-shaped connecting plate 12. A pin 9 is installed on the L-shaped connecting plate. A locking nut 8 is installed on the side of the visible guard plate 2 on the pin 9. The pin 9 forms a groove structure 13 on the side of the L-shaped connecting plate. It also includes a screw 11. A second mounting plate 14 is fixed on the lower guard plate 3. The screw 11 is installed on the second mounting plate, and the other end is located in the groove structure. A spring 10 is sleeved on the screw 11. One end of the spring 10 is limited by the second mounting plate, and the other end is limited by the boss 15 in the groove structure.
[0027] Specifically, one end of the upper guard plate 1 forms a U-shaped bend 16, and one end of the visible guard plate 2 is inserted into the U-shaped bend.
[0028] The upper guard plate 1 and the lower guard plate 3 are provided with wire protection sleeves 5, and the contactor 7 wiring passes through the wire protection sleeves 5.
[0029] The upper guard plate 1 and the lower guard plate 3 are both installed on the first mounting plate 6 by bolts.
[0030] like Figure 7 As shown, the upper part of the visible protective plate 2 is inserted into the U-shaped bend 16 of the upper protective plate 1, which achieves a quick connection and fixation function; as Figure 6 , 8 As shown, the lower part of the visible guard plate 2 engages with the pin 9 on the lower guard plate 3, and is locked in place by the locking nut 8, thus achieving a reliable connection between the visible guard plate 2 and the lower guard plate 3;
[0031] like Figures 3 to 5 As shown, the cable sheath 5 is clipped onto the upper sheath 1 and the lower sheath 3, and the contactor 7 wiring passes through the cable sheath 5, thus achieving the protection and sealing of the cable.
[0032] like Figure 6 , 8As shown, the lower guard plate 3 is equipped with pins 9, springs 10, and screws 11, which work together to achieve a telescopic fixing point. Under vibration conditions, it plays a role in buffering and shock absorption for the visible guard plate 2, so that the contactor protection level meets the requirements of the electrical industry.
[0033] The above embodiments have provided a detailed description of the present invention, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made in accordance with the claims of the present invention should still fall within the patent coverage of the present invention.
