Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a wiring terminal and an air conditioner. Background Art

[0002] As an accessory product for achieving electrical connection, terminal blocks are widely used in various electrical equipment. Terminal blocks in the prior art usually include a base, a conductive plate disposed on the base, and a wire terminal. The two edges of the base are formed with ribs extending upward from the plane of the base. Due to the interference of the ribs, the installation direction of the wire terminal is parallel to the ribs. In practical applications, when it is necessary to install wire terminals with the same orientation in two adjacent fixed positions, the usual practice is to lengthen the conductive plate of the terminal block to increase the distance between the two adjacent fixed positions, such as Figure 1-2 As shown, this causes the wiring terminal to occupy a large space and is not suitable for occasions with a small space structure. Therefore, it is necessary to improve the existing wiring terminal. Summary of the invention

[0040] In the wiring terminal of the present invention, the two edges of the base 3 extend upward to form retaining edges 30. When the wire terminal 2 is installed on the base 3, in order to avoid interference between the wire terminal 2 and the retaining edges 30, the installation direction of the wire terminal 2 is parallel to the retaining edges 30. In order to install wire terminals 2 with the same orientation between adjacent fixed positions and meet the installation space requirements of the wiring terminals, the wiring terminal of the present invention is provided with a plurality of mounting surfaces parallel to the surface of the base 3 and not coplanar with each other on the conductive plate 1, and connecting through holes for installing the wire terminals 2 are provided on the mounting surfaces. With this technical solution, the connecting through holes on each mounting surface on the conductive plate 1 are staggered in space, thereby making full use of the space perpendicular to the plane of the base 3, thereby achieving the installation of wire terminals 2 with the same orientation on adjacent connecting through holes without increasing the plane distance between adjacent connecting through holes, saving installation space, and being suitable for occasions with small spatial structures.

[0041] In an optional embodiment, the conductive plate 1 is integrally formed.

[0045] In this embodiment, the connection through hole located on the first upper mounting plate 11 near the first wall plate 12 completely overlaps with the connection through hole located on the second upper mounting plate 21 near the end of the second conductive plate 20. Through the above arrangement, the two conductive plates 1 can be fastened while fixing the wire terminal 2, thereby improving the installation reliability of the conductive plate 1 on the base 3.

[0046] Figure 5 The structure schematic diagram of the conductive plate 1 of the preferred embodiment of the present invention is shown, wherein the length of the first upper mounting plate 11 is shorter than that of the second upper mounting plate 21. Specifically, the free end of the first upper mounting plate 11 extends toward the second conductive plate 20, and the free end of the first upper mounting plate 11 exceeds the connecting through hole provided on the second upper mounting plate 21 and close to the end of the second conductive plate 20, and does not interfere with other connecting through holes on the second upper mounting plate 21. The upper surface of the first upper mounting plate 11 abuts against the lower surface of the second upper mounting plate 21. Preferably, the first upper mounting plate 11 is provided with a connecting through hole, and the second upper mounting plate 21 is provided with two connecting through holes, and the connecting through hole located on the first upper mounting plate 11 completely overlaps with the connecting through hole located on the second upper mounting plate 21 close to the end of the second conductive plate 20; the first lower mounting plate 13 and the second lower mounting plate 23 are respectively provided with a connecting through hole.

In this embodiment, by providing a base 3 adapted to the structure of the conductive plate 1, the conductive plate 1 can be matched with the base 3, and the conductive plate 1 is fixedly mounted on the base 3.

In this embodiment, the first upper mounting plate 11 and the second upper mounting plate 21 are of equal length, and accordingly, the upper end surface of the base 3 is planar, and the upper end surface of the base 3 abuts against the lower surface of the first upper mounting plate 11.

[0049] In this embodiment, the lead terminal 2 includes a first end surface 210 and a second end surface 220. In a preferred embodiment, Figure 6 As shown, a wire terminal 2 is installed at each connecting through hole, and the second end surface 220 of the wire terminal 2 abuts against the mounting surface 100 of the conductive plate 1. In another preferred embodiment, as shown in FIG. Figure 7 As shown, two wire terminals 2 are installed at each connecting through hole, and the second end faces 220 of the two wire terminals 2 are abutted against each other and fixed to the mounting surface 100 of the conductive plate 1 .

[0052] In this embodiment, at the abutment between the first upper mounting plate 11 and the second upper mounting plate 21, the screw 50 sequentially passes through the wire terminal 2, the connecting through hole located on the second upper mounting plate 21, the connecting through hole located on the first upper mounting plate 11, and the nut 40, and then extends into the countersunk hole 32, thereby fixing the wire terminal 2, the first conductive plate 10 and the second conductive plate 20 to the base 3 while fastening the first conductive plate 10 and the second conductive plate 20.

[0053] Preferably, in this embodiment, after the screw assembly is installed in place, the height of the portion of the screw assembly extending from the upper surface of the first lower mounting plate 13 is lower than the height of the first wall plate 12, and the height of the portion of the screw assembly extending from the upper surface of the second lower mounting plate 23 is lower than the height of the second wall plate 22.
