Abstract

The invention discloses a kick temperature controller which comprises an aluminum cover (1), a dual-metal disk (2), a guide frame (3), a fixed contact (5), a movable contact (6), a terminal (7), an elastic sheet (9), a fixed connecting plate (10) and a shell (11), wherein the elastic sheet is riveted with the shell through a short rivet (12), the fixed connecting plate is riveted with the shell through a support platform by using a long rivet (13), the fixed contact is riveted with the fixed connecting plate, the movable contact is riveted with the elastic sheet, and a lug boss (8) used for locating the elastic sheet is formed in an inner cavity of the shell. The kick temperature controller has the advantages of simple manufacture method, less consumed materials, easy installation and capability of greatly prolonging the service life.

Description

A kind of Kick type temperature controller

Technical field

The present invention relates to a kind of thermostat, is a kind of Kick type temperature controller specifically, and it can solve fixed contact preferably and contact the problem that the center aligns with moving contact.

Background technology

At present, the housing of Kick type temperature controller has two big types, bakelite and pottery.The effect of housing is mainly installed and is decided fishplate bar, shell fragment and leading-out terminal, decides fishplate bar riveted joint fixed contact, shell fragment riveted joint moving contact; For easy for installation and housing tolerance requirement; Housing with decide fishplate bar, shell fragment cooperates that certain clearance is all arranged, ceramic shell is because technological problems in addition, the gap is big more a lot of than bakelite; This gap causes fixed contact and moving contact off-centring, influences the useful life of Kick type temperature controller.In order to address this problem; It is spacing to shell fragment to take to add the monolateral spacing way of boss at present; But boss also will leave reasonable clearance; And boss and shell fragment gap also can be followed housing tolerance and changed greatly, and therefore, present shell structure form and localization method can not fixed, the moving contact contact off-centring problems of fine solution Kick type temperature controller.

Summary of the invention

The purpose of this invention is to provide a kind of Kick type temperature controller that solves fixed contact and moving contact off-centring phenomenon, this Kick type temperature controller manufacturing approach is simple, and is few with material, install easily, and the useful life that can significantly improve thermostat.

A kind of Kick type temperature controller provided by the invention; Include aluminium lid, bimetal disk, leading truck, fixed contact, moving contact, terminal, shell fragment, decide fishplate bar and housing; Shell fragment and housing are riveted by short rivet, decide fishplate bar through supporting station and housing by long rivet, fixed contact and decide fishplate bar and rivet; Moving contact and shell fragment riveted joint, the housing inner chamber is formed with the boss that shell fragment is positioned.

The cross section of boss dashes the circular hole that the socket boss is arranged for circular or the square housing intracavity bottom center that is positioned at, shell fragment bottom correspondence position.Perhaps, boss is one to have the fixture block on slope, is positioned at housing inner chamber supporting station bottom corresponding on short rivet and the long rivet center line, and the shell fragment relevant position has the groove of clamping boss.

Decide fishplate bar and want big near the outer rim radius ratio of long rivet one end away from the other end of long rivet, terminal has two, and one is connected with short rivet, and another is connected with long rivet.

The localization method of Kick type temperature controller of the present invention contact except that deciding fishplate bar five metals mould, can utilize existing mould, equipment, technology fully, does not increase operation, and is simple.

Fig. 2 is the vertical view before Fig. 1 does not encapsulate.

Fig. 3 is the installation diagram of the another kind of execution mode of invention.

Fig. 4 is the vertical view before Fig. 3 does not encapsulate.

Embodiment

Embodiment one

See figures.1.and.2, a kind of Kick type temperature controller provided by the invention has aluminium lid 1, bimetal disk 2, leading truck 3, fixed contact 5, moving contact 6, terminal 7, shell fragment 9, decides fishplate bar 10 and housing 11.

Housing 11 utilizes existing housing mould to revise, and molds a boss 8 at housing 11 intracavity bottom centers, boss 8 the first half chamferings, so that the bottom correspondence position is inserted in towards round-meshed shell fragment 9, the boss height should not influence shell fragment 9 work.Boss 8 is owing in the housing center, have only very little mould manufacturing tolerance, and the tolerance that production technology causes is percentagewised also very little to the center, and therefore, boss 8 positioning accuracies are higher.

With decide fishplate bar 10 near the outer rim radial design of long rivet one end for bigger than the other end away from long rivet, like Fig. 2, the radius ratio A of B place place is big, also reach preferably fixed contact with afterbody and locate than weak point, thereby economical with materials.Fixed contact 5 is riveted with deciding fishplate bar 10, moving contact 6 and shell fragment 9 riveted joints.Shell fragment 9 is manual at present, the automatic general shell fragment of Kick type temperature controller, and bottom has circular hole, and therefore, shell fragment does not need other processing, can use ready-made general part.

Terminal 7 has two, and one is connected with short rivet 12, and another is connected with long rivet 13.During installation; Terminal 7, housing 11, shell fragment 9 are put into semi-automatic short rivet machine mould successively, and short rivet 12 is just accomplished riveted joint by semi-automatic rivet driver, and shell fragment 9 is by boss 8, short rivet 12 two points location; Because boss 8 manufacturing tolerances are less, so the positioning accuracy of shell fragment is high.Install and decide fishplate bar 10, with terminal 7, the riveting shell fragment housing, decide fishplate bar 10 and put into semi-automatic long rivet driver mould successively, long rivet 13 is just riveted by semi-automatic rivet driver completion.After accomplishing rivet, load onto leading truck 3, join push rod 4, put into bimetal disk 2, aluminium lid 1 successively, accomplish last encapsulation by sealing machine.

Embodiment two

With reference to Fig. 3 and Fig. 4, be with embodiment one difference:

Housing 11; Utilize existing housing mould to revise; Decide fishplate bar 10 supporting stations bottoms corresponding to moulding one boss 8 on short rivet 12 and long rivet 13 center lines at housing 11 inner chambers; Boss 8 is one to have the fixture block on slope, and the ramp height of fixture block, gradient, bottom protrusion distance should not influence shell fragment work.Corresponding boss 8 places, shell fragment 9 bottoms open a groove, and boss 8 is bumped into the groove certain depth, makes boss 8 in the tolerance variation scope, and to the groove location, all the other are the same with embodiment 1, thereby guarantee that shell fragment has high orientation precision all the time.

Embodiment one and two housing can be bakelite or ceramic shell.
