Problems solved by technology
However, there is a big disadvantage that the screws may not be locked during the production process, or the screw self-locking function is not strong during the transportation process, causing the screws to loosen, resulting in poor contact between the power cord connector and the terminal block. This may cause electrical safety issues such as sparks and arcs during use.

This invention provides an air conditioner wiring board and an assembling method. The wiring board comprises a power line joint, a base, a strong current connecting piece, an inserting piece, a screw, a nut and a spring, wherein the strong current connecting piece and the inserting piece are arranged on the base, the inserting piece is arranged above the strong current connecting piece, the power line joint is arranged between the strong current connecting piece and the inserting piece, one end of the spring is connected with the inserting piece in an abutting mode, and the other end of the spring is connected with the base in the abutting mode. According to the wiring board, the spring can provide the spring force, and the spring force acts upon the inserting piece, so that the power line joint is in close contact with the wiring board; and by the aid of the wiring board, the safety and the reliability of the air conditioner can be improved, the after-sale failure rate can be reduced, and the maintenance cost can be reduced.
Description
technical field [0001] The invention relates to a wiring board, in particular to a wiring board for an air conditioner and an assembly method for the wiring board. Background technique [0002] One of the most important parts in the electrical box of the air conditioner is the terminal block, which is the hub that provides power for the normal operation of the whole machine. The function of supplying external power to the indoor and outdoor units of the air conditioner is realized through the wiring board. The problem that needs to be solved is how to fix the power cord with the terminal block. At present, the structure of most terminal boards is similar, and the way of fixing the power cord on the terminal board is also basically a single screw fixing method. [0003] Although the wiring board adopts a single screw fixing method, the structure is simple and the operation is convenient. However, there is a big disadvantage that the screws may not be locked during the prod...
