Embodiment 1

[0020] Such as figure 2 As shown, the jump-type thermostat with reliable electrical connection in this embodiment includes a housing 1, an aluminum cover 2, a guide frame 3, a bimetallic disc 4, an action rod 5, a connecting plate 6, and a static contact 7 The static contact piece, the movable contact assembly composed of the movable contact 8 and the shrapnel 9, the first rivet 10, the second rivet 11, the first connecting terminal 12, and the second connecting terminal 13, the operating rod 5 is installed on In the guide frame 3, the end of the action rod 5 is facing the shrapnel 9; the bimetal disc 4 is located between the aluminum cover 2 and the action rod 5; the static contact piece and the first terminal 12 are pressed by the first rivet 10 Close to the inner and outer sides of the housing 1, the shrapnel 9 and the second terminal 13 in the movable contact assembly are pressed tightly on the inner and outer sides of the housing 1 by the second rivet 11; the key is that...

Embodiment 2

[0026] In the step of installing the movable contact assembly and the second terminal 13 in this embodiment, after the head of the second rivet 11 is attached to the second terminal 13, the periphery of the mounting hole of the second terminal 13 is punched, so that The installation hole of the second connection terminal 13 is made to interfere with the body of the second rivet 11 , so as to ensure reliable connection between the second connection terminal 13 and the second rivet 11 .

[0027] In the step of installing the static contact piece and the first terminal 12 in this embodiment, after the head of the first rivet 10 is attached to the first terminal 12, the periphery of the mounting hole of the first terminal 12 is punched, so that The installation hole of the first connection terminal 12 is interference-fitted with the body of the first rivet 10 , so as to ensure reliable connection between the first connection terminal 12 and the first rivet 10 .

Abstract

A thermostat with a reliable electrical connection and an assembly method therefor, which are intended to improve the reliability of electrical connections of a movable contact (8), a stationary contact (7) and a connection terminal. In the thermostat with a reliable electrical connection, a stationary contact piece and a first connection terminal (12) compress the inner and outer sides of a housing (1) via a first rivet (10); a shrapnel (9) in a movable contact component and a second connection terminal (13) compress the inner and outer sides of the housing (1) via a second rivet (11). At least one of the first rivet (10) and the second rivet (11) has a nailing direction which is from the outer side of the housing to the inner side of the housing. The second rivet (11) is in an interference fit with the installation hole of the shrapnel (9) in a movable contact component and / or the first rivet (10) is in an interference fit with the installation hole of a fixed joint board (6). In the premise of convenient assembly, the reliability of electrical connections between the shrapnel and the connection terminal and between the fixed joint board and the connection terminal is improved, the working of the thermostat is more reliable and its service life is also prolonged.

Description

technical field [0001] The invention belongs to the technical field of home appliances, and in particular relates to a jump-type thermostat with reliable electrical connection and an assembly method thereof. Background technique [0002] The jump type thermostat used in the existing household appliances is mainly used for temperature control, overheat protection, etc., such as figure 1 As shown, the connection between the moving contact, the static contact assembly and the wiring terminal of the sudden jump thermostat product is to make the shell elastically deformed and tightened by the riveting pressure of the rivet respectively. The nail head hinders the expansion of the nail body and the interference fit with the shrapnel and the fixed plate. If the interference fit is reassembled in advance, because the thickness of the shrapnel is only about 0.2, it is easy to loosen during the assembly process. Therefore, after long-term repeated hot and cold work, This tension will ...
