[0021] The utility model is further described below in conjunction with the accompanying drawings: as shown in the figure, a leakage protection switch with temperature monitoring includes a shell 1, in which an action mechanism, a leakage protection module and a contact mechanism are arranged, the leakage module includes a circuit board 2, the contact mechanism includes a moving contact piece 3, and also includes a static contact piece 4, which is arranged in the shell and one end of which extends out of the shell; a wiring frame 42 is installed on the outer wall of the shell, and the static contact piece extends into the wiring frame for wiring; a temperature sensor 5 is arranged in the shell, connected to the circuit board signal, and has a temperature sensing piece 51 that partially extends out of the shell, a limiting groove 10 is provided on the shell, part of the temperature sensing piece is arranged in the limiting groove, the wiring frame is arranged on the outside of the temperature sensing piece, and the tail end of the temperature sensing piece is in contact with the static contact piece. The action mechanism and the leakage protection module (which can be a circuit board and a mutual inductor) can refer to the Chinese patents CN215988630U and CN216749753 U. A part of the static contact piece extends out of the shell and is arranged in the wiring frame for wiring. The principle is that the screw on the wiring frame rotates. Since the wiring frame is limited and can only move forward and backward, the wiring groove 101 formed by the static contact piece and the inner wall of the wiring frame will become smaller. It is a prior art and will not be repeated. The limit groove can be limited by the wiring frame. On the other hand, the limit groove has a channel 103 with four-sided limit at one end, which can play a better limiting effect.

[0022] In this embodiment, as shown in the figure, a fixing seat 11 is provided in the housing, and a through slot 111 is provided on the fixing seat for the stationary contact piece to extend out of the housing. The stationary contact piece is integrally formed into a wiring piece, and the structure is more compact.

[0023] In this embodiment, as shown in the figure, the fixing seat is provided with a straight groove 112 communicating with the limiting groove, part of the temperature sensing sheet is arranged in the straight groove, and the straight groove is communicated with the through groove.

[0024] In this embodiment, as shown in the figure, the straight groove and the limit groove are arranged vertically relative to each other. The corresponding temperature sensing piece also has a bent structure, so that the installation is more stable.

[0025] In this embodiment, as shown in the figure, the outer wall of the housing is provided with a wiring seat 13, the wiring seat is provided with an empty slot, and the wiring frame is provided in the empty slot. The wiring frame is provided with an empty slot, and the wiring frame moves forward and backward in the empty slot but cannot rotate, and a part of the limit slot passes through the outer wall of the wiring seat.

[0026] In this embodiment, as shown in the figure, a plurality of second wiring frames 61 are provided in the housing, and a guide groove 62 is provided in front of each second wiring frame, and the guide groove has at least one inclined surface 63 extending toward the second wiring frame, which plays a certain guiding role when wiring, and is more conducive to wiring.

[0027] In this embodiment, as shown in the figure, three second wiring frames are provided, at least two V-shaped bosses 14 are provided in the housing, and the bosses are provided between adjacent guide grooves. The guide grooves are formed between the bosses in the V shape, and the structure is relatively simple.
