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

The invention is to provide a sudden-skipping temperature controller reliable in electrical connection and an assembly method thereof, so as to improve the reliability of the electrical connection between the movable contact points and wiring terminals as well as stationary contact points and the wiring terminals. According to the sudden-skipping temperature controller reliable in electrical connection, a stationary contact sheet and a first wiring terminal are tightly pressed at the inner and outer sides of a housing through a first rivet; and a spring piece and a second wiring terminal in a movable contact point assembly are tightly pressed at the inner and outer sides of the housing through a second rivet. The key point lies in that the rivet passing direction of at least one of the first rivet and the second rivet is from the outer side of the housing to the inner side of the housing; and the second rivet is in interference fit with a spring piece installation hole in the movable contact point assembly and / or the first rivet is in interference fit with a fixation connection plate installation hole. Under the premise of convenient assembling, the method helps to improve the electrical connection reliability of the spring piece and the wiring terminal as well as a fixation connection plate and the wiring terminal, thereby enabling the sudden-skipping temperature controller to work more reliably and improving the service life of the sudden-skipping temperature controller.

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 ...
