[0006] Furthermore, the wire bundling mechanism includes mounting blocks. The mounting blocks are respectively connected to the upper sides of the left and right parts of the wiring terminal. Rotating rods are rotatably connected to the mounting blocks. Torsion springs are connected between the rotating rods and the adjacent mounting blocks. A wire pressing column is connected between the rotating rods. A gasket is connected to the wiring terminal and is located below the wire passing holes.

[0007] Furthermore, a clamping mechanism is further included. The clamping mechanism includes guide frames. The guide frames are symmetrically arranged up and down and are respectively connected to the left and right parts of the wiring terminal. Elastic sheets are connected between the guide frames and the base.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] An expandable panel switch connection device, as Figures 1-4As shown in the figure, it includes a base 1. Installation holes 2 are opened on both the left and right sides in the middle of the base 1. Alignment holes 3 that are symmetric left and right are opened on both the upper and lower parts of the base 1. A wiring terminal 4 is connected to the rear side of the base 1. Seven wire passing holes 6 are opened on the wiring terminal 4. Seven fixing bolts 5 corresponding to the wire passing holes 6 are threadedly connected to the wiring terminal 4. A plurality of heat dissipation holes 7 that are symmetric up and down are opened on the wiring terminal 4. A wire bundling mechanism 8 is arranged at the rear side of the upper part of the base 1. The wire bundling mechanism 8 includes mounting blocks 81. Mounting blocks 81 are connected to the upper sides of both the left and right parts of the wiring terminal 4. Rotating rods 82 are rotatably connected to the mounting blocks 81. Torsion springs 84 are connected between the rotating rods 82 and the adjacent mounting blocks 81. A wire pressing column 83 is connected between the rotating rods 82. A gasket 85 is connected to the wiring terminal 4. The gasket 85 is located below the wire passing holes 6.

[0019] As Figure 1 , Figure 2 and Figure 4 shown in the figure, it further includes a clamping mechanism 9. The clamping mechanism 9 includes a guide frame 91. Guide frames 91 that are symmetric up and down are connected to both the left and right parts of the wiring terminal 4. Elastic pieces 92 are connected between the guide frames 91 and the base 1. The elastic pieces 92 are slidably connected to the adjacent guide frames 91.

[0020] It should be noted that a panel switch is a common electrical device used to control the on-off of a circuit and is widely used in residential, commercial, and industrial environments. The panel switch expansion device is located at the connection between the panel switch and the wall. It can flexibly add, remove, or change the number and type of switches. During the installation process, first, lift the wire pressing column 83 upward, driving the rotating rod 82 to rotate under the action of the torsion spring 84, facilitating the wire to pass through the wire passing hole 6. Then, rotate the fixing bolt 5 to loosen it, leaving a placement position for wire connection. Next, pass the wire through the wire passing hole 6, and then reset the wire pressing column 83 downward, and the torsion spring 84 resets, thereby limiting the wire. Then, rotate the fixing bolt 5 downward to further fix the wire, thereby avoiding the situation of wire loosening. The gasket 85 can reduce the wear between the wire and the wiring terminal 4 and can play a role in protecting the wire. After the wire is fixed on the wiring terminal 4, fix the base 1 on the wall. Pass the protrusions on both the left and right sides inside the wall through the elastic pieces 92. As the base 1 is continuously pushed inward, the elastic pieces 92 slide along the guide frame 91 and gradually tighten, thereby limiting the base 1. Then, use bolts to pass through the installation holes 2 to fix the base 1 to the wall, thus completing the fixed installation of the base 1 and the wall. Finally, calibrate and clamp the position of the panel through the alignment holes 3. The heat dissipation holes 7 can timely disperse the heat generated when the panel switch is powered on, avoiding damage to the panel switch due to excessive temperature.

[0021] Those skilled in the art should understand that the above embodiments do not limit the present utility model in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present utility model.
