Detailed Embodiments

[0017] The following further describes the detailed embodiments of the present utility model with reference to the drawings.

[0018] As Figures 1-5As shown in the figure, a single-phase electric meter power connection device includes a wire fixing part and a connecting part. The wire fixing part is electrically connected to the connecting part. The wire fixing part is connected to wire 1, and the connecting part is connected to the single-phase electric meter. The wire fixing part includes four wire fixing modules. Each wire fixing module includes an installation block 2. An installation groove is formed on the outer surface of the installation block 2. A first U-shaped card slot 3 is arranged inside the installation groove. A notch is formed on the outer surface of the first U-shaped card slot 3. A moving groove communicating with the installation groove is formed inside the installation block 2. A second U-shaped card slot 4 is slidably connected inside the moving groove. The second U-shaped card slot 4 is slidably connected to the first U-shaped card slot 3 through the notch. A bolt 5 is threadedly connected to the installation block 2. One end of the bolt 5 is located inside the moving groove and is rotatably connected to the second U-shaped card slot 4. The wire fixing part further includes a bundling cavity 6. A flip-up cover 7 is arranged on the bundling cavity 6. The cover 7 is buckled with the installation block 2. The connecting part includes connecting cavities 8 with the same number as the wire fixing modules. A wiring terminal 9 is arranged inside the connecting cavity 8. A through groove 15 is formed on the outer surface of the connecting cavity 8. A pressing plate 10 is slidably connected inside the through groove 15. The pressing plate 10 is fixedly connected to the wiring terminal 9. The first U-shaped card slot 3 is electrically connected to the wiring terminal 9.

[0019] Both the first U-shaped card slot 3 and the second U-shaped card slot 4 are made of metal materials, which can be copper, aluminum, other conductive metals or alloys. The wiring terminal 9 is a mass-produced metal prefabricated part, which is commonly used for the connection between two contacts.

[0020] When fixing wire 1 into the first U-shaped card slot 3, first rotate the bolt 5 to move the second U-shaped card slot 4 out of the first U-shaped card slot 3. After the second U-shaped card slot 4 is moved out of the first U-shaped card slot 3, strip the rubber outer layer at one end of wire 1, and then place the part of wire 1 with the rubber outer layer at the bottom of the first U-shaped card slot 3. Then rotate the bolt 5 to push the second U-shaped card slot 4 to move in the moving groove. The second U-shaped card slot 4 enters the notch of the first U-shaped card slot 3 and clamps wire 1. At this time, the part of wire 1 with the rubber outer layer is located between the first U-shaped card slot 3 and the second U-shaped card slot 4. Then pull wire 1 outwards from the installation block 2, so that the part of wire 1 with the rubber outer layer stripped at one end enters the inside of the installation block 2 from the outside of the installation block 2 and moves between the first U-shaped card slot 3 and the second U-shaped card slot 4. When the movement of wire 1 is completed, continue to rotate the bolt 5. Through the dislocation of the first U-shaped card slot 3 and the second U-shaped card slot 4, wire 1 is squeezed in the first U-shaped card slot 3 and the second U-shaped card slot 4, thus completing the fixation of wire 1.

[0021] After fixing the four wires 1 to the four mounting blocks 2 respectively, the device needs to be connected to a single-phase electricity meter. Specifically, during the connection, through the pressure plate 10, the terminal 9 fixedly connected to the pressure plate 10 is slid out from the connection cavity 8. Each time, only the terminal 9 that needs to be connected currently is pushed out from the connection cavity 8. After completing the connection of this terminal 9, then the next terminal 9 is pushed out from the connection cavity 8 to prevent other unconnected terminals 9 from obstructing the terminal 9 being connected.

[0022] The convergence cavity 6 has a relatively large cavity. The first U-shaped card slot 3 is electrically connected to the terminal 9 through a wire, and the wire is stored in the convergence cavity 6. When the terminal 9 extends outwards from the connection cavity 8, the wire can enter the connection cavity 8 along with the terminal 9.

[0023] Furthermore, the pressure plate 10 is in frictional contact with the outer surface of the connection cavity 8. After the terminal 9 is pushed out from the connection cavity 8 through the pressure plate 10, due to the frictional force between the pressure plate 10 and the surface of the connection cavity 8, the position of the terminal 9 can be maintained at the same position, and at this time, there is no need to control the position of the pressure plate 10 anymore.

[0024] Furthermore, side plates 11 are symmetrically arranged on the upper surface of the installation slot. The two ends of the opening of the first U-shaped card slot 3 are respectively abutted against the side plates 11. The side plates 11 can improve the stability of the first U-shaped card slot 3 and prevent the first U-shaped card slot 3 from falling out from the opening of the installation slot. When installing the first U-shaped card slot 3, it is only necessary to push the first U-shaped card slot 3 into the installation slot from the side. The two sides of the first U-shaped card slot 3 are inclined outwards. Therefore, after the first U-shaped card slot 3 enters the installation slot, the two sides of the first U-shaped card slot 3 bend inwards, so that a relatively large frictional force is generated between the first U-shaped card slot 3 and the installation slot, and the first U-shaped card slot 3 can be stably installed in the installation slot. A contact for wire connection is arranged at the bottom of the installation slot, and the first U-shaped card slot 3 is welded to the contact by welding, so that the first U-shaped card slot 3 and the terminal 9 can be electrically connected through a wire.

[0025] Furthermore, it further includes a receiving groove 12, and the receiving groove 12 is connected to the installation slot in a through manner. When the part of the wire 1 with the rubber outer layer peeled off enters between the first U-shaped card slot 3 and the second U-shaped card slot 4, by continuously rotating the bolt 5, the second U-shaped card slot 4 continuously squeezes the wire 1 in the first U-shaped card slot 3. The exposed part of the wire 1 enters the receiving groove 12 under the extrusion of the second U-shaped card slot 4. At this time, the deformation of the wire 1 is relatively large, which means that the frictional force between the wire 1 and the first U-shaped card slot 3 and the second U-shaped card slot 4 is further increased, thereby improving the connection stability between the wire 1 and the first U-shaped card slot 3 and the second U-shaped card slot 4.

[0026] Further, one end of the housing 7 is rotatably connected to the converging cavity 6. On the outer surface of the other end of the housing 7, engaging tooth plates 13 are symmetrically arranged. On the outer surface of the mounting block 2, engaging slots 14 are formed to cooperate with the engaging tooth plates 13. The housing 7 can provide protection for the device. Before installing the wire 1 onto the mounting block 2, the housing 7 needs to be opened. After completing the installation of the wire 1, the housing 7 is buckled onto the mounting block 2. The engaging tooth plates 13 are made of plastic and can enter into the engaging slots 14 through their deformation, thereby fixing the housing 7 onto the mounting block 2.

[0027] The device can first fix the wire 1 into the first U-shaped card slot 3 and the second U-shaped card slot 4 inside the mounting block 2. Since the power connection device is not connected to the single-phase electricity meter and can move freely, the convenience of connecting the wire 1 to the power connection device is greatly improved. When connecting the power connection device to the single-phase electricity meter, since standard wiring terminals 9 are used, there is no need to perform operations such as twisting the exposed wire 1 first. The wiring terminals 9 can be directly connected to the single-phase electricity meter, improving the convenience of connecting to the single-phase electricity meter and reducing the operation difficulty of connecting to the single-phase electricity meter, making it convenient to use.
