[0020] The utility model will be further described below in conjunction with the accompanying drawings of the specification.

[0021] The utility model provides the following technical solutions:

[0022] As attached Figure 1-6 As shown, the utility model discloses a terminal 6 installation structure, including a base 1 and a protective cover 2, at least one terminal installation groove 3 is provided on the base 1, a terminal positioning hole 4 is provided on the bottom groove wall of the terminal installation groove 3, a nut column 5 is arranged in the terminal positioning hole 4, the nut column 5 extends into the terminal positioning hole 4 and is fixed with the base 1, a terminal 6 is arranged in the terminal installation groove 3, a connecting hole 7 corresponding to the nut column 5 is arranged on the terminal 6, a connecting piece 8 is arranged in the connecting hole 7, and the connecting piece 8 extends into the nut column 5 through the connecting hole 7 and is connected with the nut column 5. Specifically, in this design, by providing a base 1 for installing a large-volume terminal 6, and providing a terminal installation groove 3 for positioning the terminal 6 on the base 1, the installation position of the terminal 6 is fixed, and the shaking and displacement of the terminal 6 during the installation process are avoided. At the same time, the terminal positioning hole 4 provided on the bottom groove wall of the terminal installation groove 3 enables the terminal 6 to be accurately aligned with the nut column 5 during installation, thereby improving the installation accuracy and efficiency. Furthermore, the nut column 5 in the present design is inserted into the terminal positioning hole 4 and fixed to the base 1, thereby ensuring the stability and firmness of the nut column 5, so that the terminal 6 is not easy to fall off or loosen after installation. In addition, the setting of the nut column 5 also facilitates the installation and removal of the connector 8, and improves the maintainability and replaceability of the terminal 6.

[0023] Further, the nut column 5 is arranged in a tubular structure, and the nut column 5 has an external clamping portion 9 and an internal threaded portion 10. The external clamping portion 9 is composed of a plurality of protrusions 11 protruding from the outer surface of the nut column 5. The protrusions 11 are arranged radially at equal intervals with the central axis of the nut column 5 as the center. The hole wall of the terminal positioning hole 4 is concave to form a slot 12 corresponding to the external clamping portion 9. The external clamping portion 9 extends into the slot 12 and is clamped and fixed with the base 1. One end of the connector 8 extends into the internal threaded portion 10 and is threadedly connected with the nut column 5. Specifically, in this embodiment, the nut column 5 adopts a tubular structure design, which not only improves its structural strength, but also makes the installation process easier. The external clamping portion 9 of the nut column 5 is composed of a plurality of protrusions 11, and these protrusions 11 are arranged radially at equal intervals with the central axis of the nut column 5 as the center. This design not only ensures the stable connection between the nut column 5 and the base 1, but also avoids possible misalignment or deviation during the installation process. At the same time, the recessed slot 12 formed on the hole wall of the terminal positioning hole 4 perfectly matches the external clamping portion 9, so that the nut column 5 can accurately extend into the slot 12 and be clamped and fixed with the base 1, thereby ensuring the installation stability and reliability of the terminal 6. The internal threaded portion 10 of the nut column 5 is designed so that the connector 8 can be conveniently threadedly connected thereto. One end of the connector 8 extends into the internal threaded portion 10 and is tightly connected to the nut column 5. This connection method is both firm and reliable, and can effectively prevent the terminal 6 from falling off or loosening during installation. At the same time, the setting of the internal threaded portion 10 also facilitates the disassembly and replacement of the connector 8, and improves the maintainability and replaceability of the terminal 6.

[0024] Furthermore, the internal threaded portion 10 is an internal thread formed on the inner wall of the nut column 5, and the connecting member 8 is a screw, which extends into the interior of the nut column 5 and is threadedly connected to the nut column 5. Specifically, in this embodiment, the internal threaded portion 10 adopts an internal thread design formed on the inner wall of the nut column 5, and this design makes the connection between the nut column 5 and the connecting member 8 tighter and more stable. The connecting member 8 adopts a screw, one end of which extends into the interior of the nut column 5 and is threadedly connected to the internal threaded portion 10. This connection method is not only simple and easy, but also has high connection strength and reliability.

[0025] Furthermore, a snap-on structure is provided between the protective cover 2 and the base 1, and the snap-on structure includes an arc-shaped snap-on end 13 provided on the base 1 and a snap-on portion 14 provided on the protective cover 2, and the protective cover 2 snaps with the arc-shaped snap-on end 13 on the base 1 through the snap-on portion 14, and the protective cover 2 protects the wiring terminals 6 in the terminal installation groove 3. Specifically, in the present embodiment, the protective cover 2 and the base 1 are connected by a snap-on structure, and this connection method is not only convenient and fast, but also has good stability. The snap-on structure includes an arc-shaped snap-on end 13 provided on the base 1 and a snap-on portion 14 provided on the protective cover 2, and the protective cover 2 snaps with the arc-shaped snap-on end 13 on the base 1 through the snap-on portion 14, thereby realizing a tight connection between the protective cover 2 and the base 1. This design enables the protective cover 2 to be easily opened or closed, and is convenient for users to maintain and replace the wiring terminals 6 in the terminal installation groove 3. At the same time, the provision of the protective cover 2 can also effectively prevent dust, moisture and other debris from entering the terminal installation groove 3, thereby providing good protection for the wiring terminal 6 and ensuring the performance and life of the wiring terminal 6.

[0026] Furthermore, the lower part of the arc-shaped buckle end 13 is concave to form a buckle groove 15, and the buckle portion 14 extends into the buckle groove 15 to be buckled with the base 1.

[0027] Furthermore, two symmetrical terminal installation grooves 3 are provided on the base 1, and a base positioning portion 16 is formed between the terminal installation grooves 3, and a positioning hole 17 penetrating the base 1 is provided on the base positioning portion 16. Specifically, in this embodiment, an arc-shaped buckle end 13 is also provided on the base positioning portion 16 to increase the connection strength between the base 1 and the protective cover 2, and the provision of the positioning hole 17 can facilitate the installation of the base 1 on the electrical appliance.
