[0002] This type of electrical connector connects cables, typically connecting and securing a flexible metal conduit or metal armored cable or metal armored cable with a sheath to an electrical panel or electrical equipment. The cables include a flexible metal conduit or metal armored cable or metal armored cable with a sheath.

[0003] Metal armored cables have cables inside, and flexible metal conduits can also be used to hold cables. The above only allow cables or wires to penetrate into electrical equipment or electrical panels. Metal armored cables and flexible metal conduits are not allowed to penetrate into electrical equipment or electrical panels, otherwise it will bring certain safety hazards and damage.

[0004] Existing electrical connectors have the following installation methods: the first is a single specification, with a one-to-one correspondence between the outer diameters of conduits or cables. However, due to the tolerances in the production of cables and electrical connectors, it may not be possible to simultaneously mate with conduits or cables from different manufacturers. The second is a single specification with different reducers, which can accommodate conduits or cables of various outer diameters. However, if the connector is installed facing upward, the reducer must first be inserted into the electrical connector and held down, and then the corresponding conduit or cable must be installed onto the electrical connector using another tool. All of the above structures suffer from poor adaptability, multiple steps, and long assembly time. Utility Model Content

[0005] Therefore, it is necessary to provide an electrical connector for multiple wire diameters to solve the problems of poor adaptability, multiple operation steps and long assembly time in the existing electrical connector structure.

[0053] See also Figure 5As a preferred embodiment of the present application, a quick-connect extension 31 is provided on one side of the fixed pressure plate 30. The quick-connect extension 31 has an arc-shaped structure. The fixed pressure plate 30 contacts the assembly opening 13 of the clamping plate 12 through the quick-connect extension 31. A rotation point is formed at the contact area between the quick-connect extension 31 and the assembly opening 13 of the clamping plate 12, and a cable clamping area is formed in the area between the fixed pressure plate 30 and the clamping plate 12. During assembly, the arc-shaped quick-connect extension 31 is inserted into the assembly opening 13 of the clamping plate 12 to achieve a detachable connection between one side of the fixed pressure plate 30 and the other side of the clamping plate 12. By making the quick-connect extension 31 of the fixed pressure plate 30 an arc-shaped structure, the assembly area of ​​the fixed pressure plate 30 is stabilized after the arc-shaped structure is installed in the assembly opening 13. When the locking member 40 locks the first locking area 14 and the second locking area 32, the quick-connect extension 31 of the fixed pressure plate 30 is prevented from disengaging from the assembly opening 13 when the fixed pressure plate 30 rotates.

[0054] As a preferred embodiment of the present application, a quick-connect extension 31 is provided on one side of the fixed pressure plate 30. The fixed pressure plate 30 contacts the assembly opening 13 of the clamping plate 12 via the quick-connect extension 31. The quick-connect extension 31 of the fixed pressure plate 30 is arranged at an angle to the fixed pressure plate 30, and the contact area between the quick-connect extension 31 and the assembly opening 13 of the clamping plate 12 forms a rotation point.

During assembly, the quick-connect extension 31, which is arranged at an angle to the fixed pressure plate 30, is connected to the assembly opening 13 of the clamping plate 12, thereby achieving a detachable connection between one side of the fixed pressure plate 30 and the other side of the clamping plate 12. By arranging the quick-connect extension 31 of the fixed pressure plate 30 at an angle to the fixed pressure plate 30, the quick-connect extension 31 of the fixed pressure plate 30 is prevented from disengaging from the assembly opening when the fixed pressure plate 30 rotates while the locking member 40 locks the first locking area 14 and the second locking area 32.

[0055] As a preferred embodiment of the present application, the clamping plate 12 of the body 10 is an arc-shaped structure. By making the clamping plate 12 into an arc-shaped structure, the contact area with the cable is increased when fixing the cable, and the adaptability to cables of different sizes is improved.

[0056] See also Figure 5 As a preferred embodiment of the present application, the fixed pressure plate 30 is an arc-shaped structure. By making the fixed pressure plate 30 into an arc-shaped structure, the fixed pressure plate 30 as a clamping and fixing structure increases the contact area with the cable, thereby improving the stability of the cable clamping assembly.

[0057] According to the above structure, during the factory assembly process of the multi-wire electrical connector, the fixed pressure plate 30 is inserted into the assembly opening 13 on one side of the clamping plate 12 via the quick-connect extension 31, so that the fixed pressure plate 30 can be rotated along the contact area of ​​the assembly opening 13 via the quick-connect extension 31.
