Description

Technical Field

[0001] This utility model belongs to the field of moving contact technology, and in particular relates to a quick replacement device for moving contacts. Background Technology

[0002] Moving contacts are an indispensable component in socket manufacturing. In switch and socket production, when an electrical appliance is plugged into the corresponding two-hole or three-hole socket inside the switch and socket, the moving contact inside the switch and socket will move, causing its silver contact at the end to contact the corresponding power-carrying rod, thus connecting the electrical appliance to the power supply.

[0003] During continuous use of the socket, the moving contact becomes a relatively easy-to-wear component due to its constant movement. The connection between the moving contact and the inside of the socket is usually a fixed connection. Therefore, it is inconvenient to replace the moving contact when it is severely worn. Hence, a quick replacement device for the moving contact is proposed. Utility Model Content

[0004] This utility model provides a quick replacement device for moving contacts to solve the problem mentioned in the background art that, when using the currently common quick replacement devices for moving contacts on the market, the moving contacts are easily worn out due to continuous movement during the uninterrupted use of the socket. The connection between the moving contact and the inside of the socket is usually a fixed connection, so it is inconvenient to replace the moving contact when it is severely worn.

[0005] This utility model is implemented as follows: a quick-change device for the moving contact includes a connecting base, inside which four sets of connecting frames are installed. Inside each connecting frame is a placement groove 1. Inside the placement groove 1 is a connecting plate 1 movably connected. The bottom end of the connecting plate 1 is fixedly connected to the moving contact. Inside the connecting frame is a placement groove 2. Inside the placement groove 2 is an auxiliary block fixedly connected. Inside the auxiliary block is a connecting foot movably connected. The top end of the connecting plate 1 is fixedly connected to a snap-fit ​​block.

[0006] By referring to the above technical solution, the connection between the connecting frame and the connecting plate is made easy to connect and easy to disassemble and replace.

[0007] Preferably, a connecting rod extends through the top of the connecting frame, and the outer side of the connecting rod penetrates the interior of the auxiliary block.

[0008] Preferably, a movable column is fixedly connected to the end of the connecting rod inside the auxiliary block, and a spring is sleeved on the outside of the connecting rod.

[0009] Preferably, the inner shape of the snap-fit ​​block corresponds to the outer shape of the connecting foot, and the inner side of the snap-fit ​​block snaps into the outer side of the connecting foot.

[0010] Referring to the above technical solution, the connecting pins provide a limit for the locking block.

[0011] Preferably, a second spring is fixedly connected to the side wall of the connecting foot, and the end of the second spring away from the connecting foot is fixedly connected to the inner side wall of the auxiliary block.

[0012] Preferably, a linkage rod is rotatably connected to one side of the movable column, and the end of the linkage rod away from the movable column is rotatably connected to the end of the connecting foot. A second connecting plate is fixedly connected inside the auxiliary block, and the connecting foot is rotatably connected to one side of the second connecting plate.

[0013] Based on the above technical solution, the movement of the linkage rod was achieved by the movable column assisting in the movement of the movable column.

[0014] Preferably, the top end of spring one is fixedly connected to the top end of placement groove two, and the bottom end of spring one is fixedly connected to the top end of movable column.

[0015] Based on the above technical solution, the movable rebound of the spring-auxiliary connecting rod was achieved.

[0025] This utility model embodiment provides a quick replacement device for the moving contact, such as... Figure 1-4 As shown:

[0026] Reference Figure 1 and Figure 2 The quick-change device for the moving contact includes a connecting base 1. Four sets of connecting frames 2 are installed inside the connecting base 1. The connecting frames 2 have a placement slot 3 inside, which provides space for the placement slot 3. A connecting plate 5 is movably connected inside the placement slot 3. The bottom end of the connecting plate 5 is fixedly connected to the moving contact 4. The connecting plate 5 assists in the connection between the moving contact 4 and the connecting frame 2. A second placement slot 6 is opened inside the connecting frame 2. An auxiliary block 7 is fixedly connected inside the second placement slot 6, which provides space for the auxiliary block 7.

[0027] Reference Figure 3 and Figure 4The auxiliary block 7 has an internally connected connecting foot 10, which is L-shaped. A locking block 9 is fixedly connected to the top of the connecting plate 5, and the connecting foot 10 provides a limit for the locking block 9. A connecting rod 8 passes through the top of the connecting frame 2, and its outer side penetrates the interior of the auxiliary block 7. A movable column 13 is fixedly connected to the end of the connecting rod 8 inside the auxiliary block 7. A spring 14 is sleeved on the outer side of the connecting rod 8, assisting in the movement and rebound of the connecting rod 8. The inner shape of the locking block 9 corresponds to the outer shape of the connecting foot 10, and the inner side of the locking block 9 engages with the outer side of the connecting foot 10. A second spring 15 is fixedly connected to the side wall of the connecting foot 10, assisting in the movement and support of the connecting foot 10. The end of the second spring 15 away from the connecting foot 10 is fixedly connected to the inner side wall of the auxiliary block 7. A linkage rod 11 is rotatably connected to one side of the movable column 13, and the end of the linkage rod 11 away from the movable column 13 is rotatably connected to the end of the connecting foot 10. The auxiliary block 7 is internally fixedly connected to a connecting plate 2 12. The connecting foot 10 is rotatably connected to one side of the connecting plate 2 12. The top of the spring 14 is fixedly connected to the top of the placement groove 2 6, and the bottom of the spring 14 is fixedly connected to the top of the movable column 13. The connecting plate 5 at the top of the moving contact 4 is inserted into the placement groove 3. When the moving contact 4 needs to be disassembled and replaced due to continuous use, simply push the connecting rod 8. The connecting rod 8 drives the movable column 13 to move. At this time, the linkage rod 11 rotates, which in turn drives the end of the connecting foot 10 to rotate, shortening the distance between the two sets of connecting feet 10. This provides space for the locking block 9 to disengage from the limit of the connecting foot 10. The connecting plate 2 12 provides connection support for the rotation of the connecting foot 10, improving the stability of the device. When the connecting foot 10 moves, the spring 2 15 provides movement support and rebound for the connecting foot 10, ensuring the stability of the movement of the connecting foot 10, thereby improving the replacement rate of the moving contact 4.

[0028] Working principle: First, when using this quick-change device for moving contacts, the connecting plate 5 at the top of the moving contact 4 is inserted into the placement slot 3. When the moving contact 4 needs to be disassembled and replaced due to continuous use, simply push the connecting rod 8. The connecting rod 8 drives the movable column 13 to move, and the linkage rod 11 rotates, which in turn drives the end of the connecting foot 10 to rotate, shortening the distance between the two sets of connecting feet 10. This provides space for the locking block 9 to disengage from the limit of the connecting foot 10. The connecting plate 12 provides connection support for the rotation of the connecting foot 10, improving the stability of the device.

[0029] Secondly, when the connecting foot 10 moves, the second spring 15 provides support and rebound for the connecting foot 10, ensuring the stability of the connecting foot 10's movement, thereby improving the replacement rate of the moving contact 4 and finally completing the work.
