Abstract
The utility model discloses a thermodynamic over-current relay locking structure, comprising an upper shell, a lower shell, and cover boards arranged at the rear sides of the upper shell and the lower shell, wherein more than one neck and locating slot are arranged at the bottom surface of the upper shell; corresponding quantity of strip grabs and locating bumps are arranged at the top surface of the lower shell; the upper shell is pushed into the lower shell in a parallel manner, so that the necks of the upper shell and the strip grabs of the lower shell are locked and fixed with one another, and the locating slots of the upper shell and the locating bumps of the lower shell are mutually assembled; and the necks of the upper shell and the corresponding grabs of the lower shell form a buckled T-shaped structure. According to the thermodynamic over-current relay locking structure, a modular design is adopted, therefore, the thermodynamic over-current relay locking structure can be applicable to different models, and has the advantages of being convenient to assemble and dismantle, and the like.
Description
Technical field
The utility model discloses the moving overcurrent relay snap-in structure of a kind of heat, divides by International Patent Classification (IPC) (IPC) to belong to relay system technology for making field, and this snap-in structure is suitable for assembling different types.
Background technology
The moving overcurrent relay 10 of present heat mainly comprises a housing 11 and cover plate 12, as shown in Figure 1, this housing 11 is to cooperate the internal mechanical element and design integrated hollow structure, mechanical organ wherein comprises contact terminal, alloy sheets, start connecting rod, interlock plate and calandria etc., and described cover plate 12 covers and is fixed in housing 11 posterior dorsals; Since housing 11 be one-body molded among hollow structure, when above-mentioned mechanical organ is installed, need take a long time just with the certain hyte dress of one, in addition, when in the housing 11 component wear being arranged, because can't singlely changing, will cause the moving overcurrent relay 10 of heat to need integral body to abandon, thereby the increase cost, and cause user's inconvenience.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of heat rational in infrastructure, adaptable to move the overcurrent relay snap-in structure, and this engaging mode can be assembled in different types, effectively the saving group immediately between, and part is oversimplified.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of heat is moved the overcurrent relay snap-in structure, comprises that upper shell and lower house and one are installed on the cover plate of upper shell and lower house rear side,
Upper shell, it is the hollow housing of inner installing relay assembly, this upper shell bottom surface is provided with an above draw-in groove and location notch, and fixes with the lower house end face;
Lower house, its end face is provided with strip grab and the positioning convex of respective amount, described upper shell is pushed into lower house with parallel mode, so that the strip grab of the draw-in groove of upper shell and lower house is fixed mutually, and makes the mutual assembly of positioning convex of location notch and the lower house of upper shell.
Further, described upper shell is provided with two parallel draw-in grooves, and the strip grab assembly that two draw-in grooves are corresponding with lower house forms the T shape structure of mutual buckle.
Further, the initial contact-making surface that engages with upper shell of the positioning convex of described lower house is the inclined-plane.
This upper shell was pushed into lower house with parallel mode when the utility model mainly was to assemble, so that the mutual assembly of the grab of the draw-in groove of upper shell and lower house, and make the location notch of upper shell and the location grab of lower house cooperatively interact fixing, can finish the assembly operation of upper and lower casing, therefore when upper shell or lower house break down, only need to change out of order upper shell or lower house, so then can effectively reduce maintenance time and maintenance cost; In addition, because the utility model adopts modular design, therefore applicable to different types, have the advantages such as assembling, convenient disassembly.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: see also Fig. 2 to Fig. 4, a kind of heat is moved the overcurrent relay snap-in structure, comprises that upper shell 20 and lower house 21 and are installed on the cover plate 22 of upper shell and lower house rear side;
As shown in Figures 3 and 4, this upper shell 20 was pushed into lower house 21 with parallel mode when the utility model mainly was to assemble, so that the groove 30 of upper shell 20 and the strip barb 32 mutual assembly of lower house 21, and the location notch 31 of upper shell 20 and the positioning convex 33 of lower house 21 are interfixed, can finish the assembly operation of upper shell 20 and lower house 21, cover plate 22 is installed and fixed to upper shell 20 and lower house 21 rear sides more at last, can finish the assembling of this creation.Therefore, when the upper shell 20 of the moving overcurrent relay of heat or lower house 21 fault, only need to change upper shell 20 or the lower house 21 of fault, so then do not need the moving overcurrent relay of whole heat is abandoned, reduce maintenance time and maintenance cost.
The moving overcurrent relay snap-in structure of the utility model heat adopts modular design, therefore applicable to the moving overcurrent relay assembling of dissimilar heat.
The above record, only for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do all belong to the claim that this creation is advocated, and are not limited to those disclosed embodiments.
Claims (3)
1. a heat is moved the overcurrent relay snap-in structure, comprises that upper shell and lower house and one are installed on the cover plate of upper shell and lower house rear side, is characterized in that:
Upper shell, it is the hollow housing of inner installing relay assembly, this upper shell bottom surface is provided with an above draw-in groove and location notch, and fixes with the lower house end face;
Lower house, its end face is provided with strip grab and the positioning convex of respective amount, described upper shell is pushed into lower house with parallel mode, so that the strip grab of the draw-in groove of upper shell and lower house is fixed mutually, and makes the mutual assembly of positioning convex of location notch and the lower house of upper shell.
