a connecting rod 8 is connected to the middle of the bottom surface of the connecting piece 6, the connecting rod 8 and the connecting piece 6 are perpendicular to each other, a slot for the connecting rod 8 to enter and move is formed in the base 1, the bottom of the slot is communicated with an accommodating cavity, a moving contact 11 and a static contact 12 are installed in the accommodating cavity, the static contact 12 is located below the moving contact 11, a platform support 9 is fixedly connected to the moving contact 11, a spring 10 is sleeved on the platform support 9, and the spring 10 is fixedly connected with the base 1;
the moving contact 11 and the static contact 12 are both electrically connected with the monitoring device 15;
the connecting portion 602 of the connecting piece 6 is connected with the second terminal 3, the first compression screw 4 is screwed to compress the first end of the connecting piece 6, and when the second compression screw 5 is screwed to compress the connecting portion 602 of the connecting piece 6, the connecting rod 8 is pressed downwards to the platform support 9, so that the movable contact 11 moves downwards and is communicated with the fixed contact 12.
It should be noted that the monitoring device 15 described in this embodiment is a device in the prior art, and may be an LED display device, that is, when the movable contact 11 and the static contact 12 are conducted, the monitoring device 15 may emit red light, that is, it is described that the protection pressing plate is in an "in-place" state, when the movable contact 11 and the static contact 12 are not conducted, the monitoring device 15 does not emit light, and the worker may determine that the protection pressing plate is in an "exit" state
Through the design, as shown in fig. 4, only when the connecting portion 602 of the connecting piece 6 is connected to the second terminal 3 and the first compression screw 4 compresses the first end of the connecting piece 6, and the second compression screw 5 compresses the connecting portion 602, the connecting rod 8 is pressed downwards to press the platform pillar 9, so that the movable contact 11 moves downwards to be communicated with the static contact 12, and then the monitoring device 15 is operated to send a signal of putting in place, and a worker can judge whether the protection pressing plate is put in place only according to the signal of putting in place, thereby avoiding judgment errors caused by visual observation of the worker, and improving the operation safety of a power grid;
as shown in fig. 4, when the first compression screw 4 does not compress the first end of the connecting piece 6, and the second compression screw 5 does not compress the connecting portion 602 of the connecting piece 6, because the spring 10 is connected to the platform support 9, the acting force of the spring 10 is used to keep the platform at a higher position inside the accommodating cavity without being pressed by the connecting rod 8, so that the movable contact 11 and the fixed contact 12 are in a disconnected state, and therefore, the monitoring device 15 cannot operate.
As shown in fig. 5, when the first compression screw 4 does not compress the first end of the connecting piece 6, and the second compression screw 5 compresses the connecting portion 602 of the connecting piece 6, the platform support 9 cannot drive the moving contact 11 to be conducted with the static contact 12 due to insufficient pressure generated by the connecting rod 8 on the platform support 9, and therefore the monitoring device 15 cannot operate.
Furthermore, an operating handle 7 is fixedly mounted on the connecting piece 6, and the operating handle 7 is fixed in the middle of the top surface of the connecting piece 6.
It should be noted that the design of the operating handle 7 can facilitate the worker to rotate the connecting piece 6.
Further, the slot is an arc slot.
It should be noted that, the shape of the slot needs to be designed according to the movement track of the connecting rod 8, and since the connecting piece 6 is connected to the connecting portion 602 and the second terminal 3 only after rotating a preset angle, the movement track of the connecting rod 8 forms an arc, and therefore, the shape of the slot needs to be designed into an arc shape, so that the connecting rod 8 can enter and exit.
Further, the platform column 9 includes a hat-shaped platform and a column body;
the top surface of the hat-shaped platform is a curved surface, the bottom surface of the hat-shaped platform is a plane, and the top end of the strut body is fixedly installed at the center of the bottom surface of the hat-shaped platform.
Further, the spring 10 is sleeved on the pillar body, and the spring 10 is fixedly connected with the base 1.
Further, the bottom of the first terminal 2 and the bottom of the second terminal 3 both penetrate through the base 1;
the bottom of the first binding post 2 and the bottom of the second binding post 3 are both connected with two binding screws 13 and a connecting wire 14, and the connecting wire 14 is located between the two binding screws 13.
Further, the connecting portion 602 is a semicircular notch;
the diameter of the semicircular gap is matched with that of the second binding post 3.
It should be noted that, with the above-described design, the connection portion 602 can be fitted into the second post 3.
Furthermore, a metal screw is arranged at the top of the first binding post 2 and the top of the second binding post 3, the metal screws are used for connecting the first compression screw 4 and the second compression screw 5 in a threaded manner, the first end of the connecting piece 6 is sleeved on the metal screw of the first binding post 2, and the connecting part 602 of the connecting piece 6 can be embedded into the metal screw of the second binding post 3.
It should be noted that the first terminal 2 and the second terminal 3 are both parts of a conventional common plate, and the specific structure thereof is not shown in detail in the drawings.
The working principle of the protective pressing plate in the embodiment is as follows:
when the worker unscrews the first compression screw 4 and the second compression screw 5, and the operation handle 7 on the connecting piece 6 is held by the hand to enable the connecting part 602 of the connecting piece 6 to be inserted into the second binding post 3 in a poking mode, the connecting rod 8 perpendicular to the connecting piece 6 reaches the tail end of the groove along the groove (the shape groove) of the base 1, at the moment, the bottom of the connecting rod 8 is right opposite to the position right above the platform pillar 9 inside the base 1, and at the moment, the connecting piece 6 is ensured to be placed in place.
When the first compression screw 4 is screwed down, the first end of the connecting piece 6 moves down to the right position to drive the connecting rod 8 to move down, but because the connecting part 602 is not compressed by the second compression screw 5 yet, the two ends of the connecting piece 6 are unbalanced, the connecting rod 8 on the connecting piece 6 is not in the middle of the top surface of the hat-shaped platform in the platform pillar 9 and slides to the side of the second compression screw 5 which is not screwed down, the situation that the downward pressing stroke of the connecting rod 8 to the platform pillar 9 is insufficient occurs, and the movable contact 11 and the static contact 12 cannot be communicated. Only when the second hold-down screw 5 is also tightened, the connecting rod 8 returns to the position right above the hat-shaped platform in the platform pillar 9 again, the downward pressing stroke of the connecting rod 8 to the platform pillar 9 is in place, the moving contact 11 and the static contact 12 are conducted, the monitoring device 15 can know that the protection pressing plate is put in place, and otherwise, the condition that other moving contacts 11 and static contacts 12 are not conducted is monitored to be in an exit state.
The above is to the utility model provides a protection clamp plate has carried out the detailed introduction, to the general technical personnel in this field, the foundation the utility model discloses the thought of embodiment all has the change part on concrete implementation and application scope, to sum up, this description content should not be understood as right the utility model discloses a restriction.
