[0020] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 、 Figure 2 As shown, the portable electrical isolator includes an end shell 1, which is fixedly arranged on both sides of the disconnector. A plurality of assembly grooves 2 are provided on the surface of the end shell 1, and an extension groove 21 is provided on the edge of the assembly groove 2. The extension groove 21 passes through the edge of the end shell 1. The terminal pieces 3 of the disconnector are aligned with the assembly grooves 2 one by one. The terminal pieces 3 extend and fit on one side of the assembly groove 2. An extrusion assembly is provided on the other side of the assembly groove 2. A connecting plate 7 is located at the bottom of the end shell 1 to connect the various extrusion assemblies. One end of the connecting plate 7 is bent upward at a right angle. A stud 71 is threaded through the bent portion of the connecting plate 7 and is rotatably connected to the end shell 1.

[0022] The conductor piece 6 is fixed at the line end of the distribution equipment. When assembling the line, the conductor piece 6 of each aligned line is inserted into the aligned assembly slot 2, the line passes through the extension slot 21, the conductor piece 6 is aligned with the terminal piece 3, and the rotating stud 71 pushes the connecting plate 7 to move, so that the extrusion components in each assembly slot 2 move laterally synchronously. The extrusion component squeezes the conductor piece 6 and the terminal piece 3 to fit together, realizing rapid assembly and connection of the line.

[0023] like Figure 3 As shown, the extrusion assembly includes a push block 5 and an extrusion block 4. Both the push block 5 and the extrusion block 4 slide in the assembly groove 2. The extrusion block 4 is close to the terminal piece 3. The bottom of the push block 5 is connected to the connecting plate 7. The extrusion block 4 is connected to the push block 5 through a spring.

[0024] The rotating stud 71 pushes the connecting plate 7 to drive the push block 5 to move laterally. The push block 5 pushes the extrusion block 4 toward the conductor piece 6 through the spring. The conductor piece 6 squeezes the extrusion block 4 to fit the terminal piece 3, and the spring between the extrusion block 4 and the push block 5 is used to elastically clamp the conductor piece 6 and the terminal piece 3 to prevent the conductor piece 6 from being excessively squeezed and deformed.

[0025] A flexible insulating layer 42 is provided on one side of the extrusion block 4 opposite to the conductor sheet 6 . The flexible insulating layer 42 can be made of rubber material, so that the extrusion block 4 is in flexible contact with the conductor sheet 6 , further protecting the conductor sheet 6 from deformation under pressure.

[0026] like Figure 2 、 Figure 3 As shown, the conductor sheet 6 is a right-angled sheet. The side of the conductor sheet 6 connected to the circuit contacts the inner wall of the assembly slot 2, so that the conductor sheet 6 will not be pulled out along the direction of the circuit. The extrusion block 4 is fixed with an auxiliary pressure block 41. When the extrusion block 4 squeezes the conductor sheet 6, the auxiliary pressure block 41 squeezes the circuit in the extension slot 21, thereby improving the stability of the circuit assembly connection.

[0027] The terminal piece 3 and the conductor piece 6 are in a continuously curved shape with matching shapes, which increases the contact area of ​​the terminal piece 3 and the conductor piece 6, improves the conductivity, and reduces the heat generated at the contact part. In addition, the terminal piece 3 and the conductor piece 6 have a biting effect when they are attached, which improves the connection stability between the terminal piece 3 and the conductor piece 6.

[0028] like Figure 1 、 Figure 4 As shown, the top of the assembly slot 2 is provided with a cover plate 8, which is connected to the push block 5. When the push block 5 and the extrusion block 4 move laterally to extrude the conductor piece 6 and fit the terminal piece 3, the cover plate 8 moves to block the top of the assembly slot 2, which is used to provide dustproof protection for the connecting part and also improve the protection effect of the connecting part against leakage.

[0029] like Figure 4As shown, both ends of the push block 5 are fixedly connected to the connecting plate 7 and the cover plate 8 by screws, which facilitates the processing and assembly of the device.

[0030] 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.
