Embodiment 1

[0033] see figure 1 and figure 2 , a sudden jump temperature controller, including: fixed contact 6, moving contact 5, reed 7, guide frame 3, ceramic rod 4, disc 2, housing 9 and cover 1; fixed contact 6 Fixed on the housing 9; the reed 7 has a fixed end and a movable end, the fixed end of the reed 7 is fixed on the housing 9; the moving contact 5 is fixed on the movable end of the reed 7; the guide frame 3 has Guide hole, the guide frame 3 is located above the housing 9; the disc 2 is located above the guide frame 3; the ceramic rod 4 passes through the guide hole of the guide frame 3 and is placed between the reed 7 and the disc 2; the cover 1 is located on the Above the guide frame 3, an activity space for the disc 2 is formed between the cover 1 and the guide frame 3, and the cover 1 encapsulates the guide frame 3 and the housing 9 together; the guide frame 3 and the housing 9 are provided with Chamfer 10; There is a gap 11 between the guide frame 3 and the housing 9; T...

Embodiment 2

[0043] The only difference between this embodiment and Embodiment 1 is that: the jump-type thermostat also includes two terminals 13; the two terminals 13 are fixedly installed on the housing 9, and the two terminals 13 are connected to the fixed contact 6 and the The reed 7 is electrically connected.

[0044]As a commonly used electrical component, the jump thermostat has a wide range of uses, and the connection form with other electrical equipment is not limited to only one. In order to facilitate connection with other electrical equipment, in this embodiment, preferably, two terminals 13 are provided to electrically connect with the fixed contact 6 and the reed 7 respectively. Other electrical devices only need to be electrically connected to the terminal 13, and then they can be connected to the fixed contact 6 and the reed 7 through the terminal 13 to form an electrical circuit.

Embodiment 3

[0046] A packaging method for a snap thermostat, comprising the following steps:

[0047] 1) Fix the fixed contact, reed and moving contact in the housing, the chamfer of the housing is arranged opposite to the chamfer of the guide frame, place the disc on the guide frame, and the ceramic rod is against the reed and disc Between the pieces, the cover is set on the guide frame, and there is a rod adjustment gap between the shell and the guide frame;

[0048] 2) On the outside of the cover, the position where the adjustment rod gap is located is pressurized in the radial direction, and the limit groove of the cover is processed, and the limit groove closely fits the chamfer on the guide frame and the housing;

[0049] 3) Continuously apply pressure in the axial direction between the cover and the housing, so that the gap between the adjusting rod is gradually reduced, and the limit groove is gradually deformed under pressure until the fixed contact and the moving contact are ful...

Abstract

The invention provides a novel kick type temperature controller and a packaging method thereof. The novel kick type temperature controller comprises a fixed contact, a moving contact, a reed, a guide body, a ceramic rod, a disc, a housing and a capping. The fixed contact is fixed on the housing; the fixation end of the reed is fixed on the housing; the moving contact is fixed at the movable end of the reed; the guide body is disposed above the housing; the disc is disposed above the guide body; the ceramic rod abuts against the portion between the reed and the disc; the capping is disposed above the guide body in a covering mode; the capping packages the guide body and the housing together; the guide body and the housing are provided with a chamfering; an adjusting rod gap is arranged between the guide body and the housing; the chamfering and the adjusting rod gap form an adjusting rod groove; the capping is provided with a limiting groove; and the limiting groove is closely attached to the chamfering on the guide body and the housing. According to the invention, the adjusting rod gap of the novel kick type temperature controller is adjusted during packaging, so that the working reliability is guaranteed, the structure is simple, the packing is convenient, the parts are simple, no material is wasted, and the cost is low.

Description

technical field [0001] The invention relates to the field of electrical safety components, in particular to a jump-type temperature controller and a packaging method thereof. Background technique [0002] The jump thermostat is a safety component widely used in electrical appliances, and is used for overheating and power-off protection of electrical appliances. The main action parts of the sudden jump thermostat include: fixed contact, moving contact, reed, ceramic rod, guide frame, disc, shell and cover. The fixed contact is fixed on the shell, and the moving contact is installed on the reed. The ceramic rod passes through the guide frame and rests between the reed and the disc. The cover is riveted together with the housing and the guide frame. [0003] Under normal conditions, the fixed contact is in contact with the moving contact, and is connected with the reed to form a circuit. When the working environment temperature exceeds the preset value, the disc suddenly ju...
