Description

Technical Field

[0001] The utility model relates to a mid-circuit relay with adjustable pins, belonging to the technical field of mid-circuit relays. Background Art

[0002] A mid-circuit relay is an electrical component that plays a control and protection role in the circuit. It converts small current signals into large current signals, or converts low voltage signals into high voltage signals to meet the needs of different devices. It provides isolation between different circuits to prevent interference and fault propagation between circuits. The on and off of the circuit can be controlled by controlling the on and off of the relay, thereby realizing remote control of the equipment.

[0003] According to the authorized patent CN202122756012.5, the utility model is equipped with a series of structures to enable the device to adjust the current transmission direction of the second pin during use, so that the device can meet various installation and use requirements, reduce the limitations of the device, and improve the protection effect of the relay body without affecting the heat dissipation of the relay body.

[0004] However, this patent only implements the regulation of pin current. However, due to the different positions and lengths of external wires, it is sometimes impossible to make contact with the pins, which in turn leads to the inability to connect with the relay. At the same time, when the relay is not in use, the pins will be exposed on the outside of the device, and there is no protective device on the outside of the device, so the pins are easily damaged by collision. Utility Model Content

[0010] Furthermore, the connecting plate is slidably connected to the outer side of the relay body through a sliding frame, and the retracting rod is rotatably connected between the two stabilizing plates.

Since the bottom of the nylon rope is fixedly connected to the outside of the connecting plate, the connecting plate can drive the pin plate to move outside the relay body.

At this time, the protective plate can be limited, thereby achieving the effect of protecting the pin plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1, please refer to Figures 1-6 , the utility model provides a technical solution:

[0027] A pin-adjustable mid-circuit relay comprises a relay body 1, an inner wall of the relay body 1 being provided with a movable groove 2, an interior of the movable groove 2 being slidably connected to a sliding frame 3, an interior of the sliding frame 3 being installed with a signal line 4, an outer side of the sliding frame 3 being fixedly connected to a connecting plate 5, an outer side of the connecting plate 5 being fixedly connected to a pin plate 6, an outer side of the relay body 1 being fixedly connected to a stabilizing plate 7, an outer side of the stabilizing plate 7 being fixedly connected to a movable tube 8, an inner side of the movable tube 8 being rotatably connected to a rotating rod 9, an outer side of the rotating rod 9 being fixedly connected to a retracting rod 10, an outer side of the retracting rod 10 being wrapped with a nylon rope 11, an outer side of the movable tube 8 being fixedly connected to a connecting plate 12, an outer side of the connecting plate 12 being fixedly connected to a rubber ring 13, an inner side of the rubber ring 13 being movably connected to a clamping rod 14, and a positioning hole 15 being provided in the inner wall of the movable tube 8.

[0028] Specifically, such as Figure 1 As shown, one end of the signal line 4 is fixedly connected to the inside of the relay body 1, and the other end of the signal line 4 is fixedly connected to the outside of the pin plate 6. The connecting plate 5 is slidably connected to the outside of the relay body 1 through the sliding frame 3. The retracting rod 10 is rotatably connected between the two stabilizing plates 7. The bottom of the nylon rope 11 is fixedly connected to the top of the connecting plate 5. The positioning holes 15 are evenly distributed in the inner wall of the movable tube 8, and one end of the clamping rod 14 is clamped inside the positioning hole 15.

[0029] In this embodiment: by providing a relay body 1, the pin plate 6 is electrically connected to the relay body 1 through the signal line 4. When the position of the pin plate 6 needs to be adjusted, the clamping rod 14 is first moved inside the rubber ring 13 so that the bottom of the clamping rod 14 is moved out of the positioning hole 15 inside the movable tube 8. At this time, the rotating rod 9 is rotated to drive the retracting rod 10 to rotate between the two stable plates 7, thereby driving the nylon rope 11 to tighten or loosen. Since the bottom of the nylon rope 11 is fixedly connected to the outside of the connecting plate 5, the connecting plate 5 can drive the pin plate 6 to move outside the relay body 1. When it moves to the appropriate position, the clamping rod 14 is moved inside the rubber ring 13 so that one end of the clamping rod 14 enters the inside of the positioning hole 15 again, thereby achieving the effect of being able to adjust the position of the pin plate 6.

[0030] Example 2, please refer to Figure 1 、 Figure 2 and Figure 6 The difference between this embodiment and embodiment 1 is that: a fixed plate 16 is fixedly connected to the outer side of the relay body 1, a rotating rod 17 is rotatably connected between the fixed plates 16, a protective plate 18 is fixedly connected to the outer side of the rotating rod 17, and a groove 19 is formed inside the protective plate 18; an extension plate 20 is fixedly connected to the outer side of the relay body 1, a guide tube 21 is fixedly connected to the outer side of the extension plate 20, an insertion rod 22 is movably connected to the interior of the guide tube 21, and a compression spring 23 is fixedly connected to the outer side of the insertion rod 22.

[0031] Specifically, such as Figure 1-6 As shown, the protective plate 18 is movably connected to the outside of the relay body 1 through the rotating rod 17, the extension plate 20 is symmetrically distributed on the outside of the relay body 1, and the end of the compression spring 23 away from the insertion rod 22 is fixedly connected to the outside of the conduit 21, and the outer diameter of the insertion rod 22 is smaller than the inner diameter of the groove 19.

[0032] In this embodiment: by providing a relay body 1, a fixed plate 16 is fixedly connected to the outside of the relay body 1. When the pin plate 6 needs to be protected, the protective plate 18 is first driven to rotate on the outside of the relay body 1 by the rotating rod 17. At this time, the protective plate 18 will rotate to the outside of the pin plate 6. The insertion rod 22 inside the conduit 21 moves inside the conduit 21 under the action of the compression spring 23, so that the insertion rod 22 enters the groove 19 inside the protective plate 18. At this time, the protective plate 18 can be limited, thereby achieving the effect of protecting the pin plate 6.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
