A kind of circuit board assemblies mounting structure
Technical field
The utility model relates to a kind of circuit board assemblies mounting structure, the particularly mounting structure of electric cooker circuit board assemblies, belongs to the improvement technology of circuit board assemblies mounting structure.
Background technology
At present, the circuit board assemblies mounting structure of commercially available electric cooker product as shown in Figure 1, comprise display panel 1, power panel 2, key support 3, some screws 4, some screws 6 and L shaped circuit board support 5, display panel 1 is fixed on one of them face of circuit board support 5 by screw 4, key support 3 by a plurality of buckle spiral-locks on display panel 1, power panel 2 is fixed on by screw 6 on another face of circuit board support 5, and display panel 1, power panel 2 and L shaped circuit board support 5 mutual group are dressed up circuit board assembly; Because the circuit board assembly overall volume of this structure is bigger than normal, the inner space that therefore takies pot body is more, has not only increased the cost of product, and comparatively complexity is installed, and production efficiency is not high.
Summary of the invention
The purpose of this utility model be to consider the problems referred to above and provide a kind of reasonable in design, simple and compact for structure, volume is small and exquisite, parts are few, install simple and easy quick, can increase substantially production efficiency and lower-cost circuit board assemblies mounting structure.
The technical solution of the utility model is: a kind of circuit board assemblies mounting structure, comprise display panel, power panel, key support, first securing member and second securing member, it is characterized in that described display panel is fixed on the key support by first securing member, power panel is positioned at the outside of display panel and is fixed on the key support by second securing member, and neither contact with each other yet different with the power panel setting height(from bottom) of display panel do not interfere with each other.
Described key support is inside and outside two-stage mounting structure, correspondence is installed in inboard display panel, key support is provided with two above low level screw posts, innerly on one lateral edges of key support be provided with two above low level buckles, correspondence is installed in the power panel in the outside, key support is provided with high-order screw post more than two, is provided with high-order buckle more than two with outer on the edge of low level buckle homonymy, and the periphery of key support is provided with two above installing holes.
Also be provided with the guide vane end stop that limits display panel and power panel in-plane displancement more than two on the outer rim of described key support.
Corresponding low level screw post is provided with two above installing holes on the described display panel, and a side of display panel is resisted against on the guide vane end stop, and opposite side is installed in the low level buckle, and first securing member passes installing hole display panel is fixed on the low level screw post.Corresponding high-order screw post is provided with two above installing holes on the described power panel, and a side of power panel is resisted against on the guide vane end stop, and opposite side is installed in the high-order buckle, and second securing member passes installing hole power panel is fixed on the high-order screw post.
The utility model because adopt display panel to be directly installed on the key support with power panel and setting height(from bottom) different neither contact with each other also do not interfere with each other and structure, the functional unification with key support and circuit board support of innovation, abandoned the structure that traditional separation is provided with fully, make circuit board assembly simple and compact for structure, not only reduce amount of parts, the corresponding product cost that reduced, and dwindled pot body volume inside greatly and taken, install simple and easy fast simultaneously, increased substantially production efficiency.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 2, the utility model circuit board assemblies mounting structure, comprise display panel 1, power panel 2, key support 3, first securing member 4 and second securing member 6, display panel 1 is fixed on the key support 3 by first securing member 4, power panel 2 is positioned at the outside of display panel 1 and is fixed on the key support 3 by second securing member 6, and neither contact with each other yet different with power panel 2 setting height(from bottom)s of display panel 1 do not interfere with each other.
As shown in Figure 3, described key support 3 is inside and outside two-stage mounting structure, correspondence is installed in inboard display panel 1, key support 3 is provided with three low level screw posts 33, one lateral edges of key support 3 is inner to be provided with two low level buckles 31, correspondence is installed in the power panel 2 in the outside, key support 3 is provided with three high-order screw posts 34, be provided with two high-order buckles 32 with outer on the edge of low level buckle 31 homonymies, the periphery of key support 3 is provided with three installing holes 36, also is provided with the guide vane end stop 35 of two restriction display panels 1 and power panel 2 in-plane displancements on the outer rim of key support 3.
Shown in Fig. 2,3, corresponding low level screw post 33 is provided with three installing holes 12 on the described display panel 1, one side of display panel 1 is resisted against on the guide vane end stop 35, and opposite side is installed in the low level buckle 31, and first securing member 4 passes installing hole 12 display panel 1 is fixed on the low level screw post 33.Corresponding high-order screw post 34 is provided with three installing holes 22 on the described power panel 2, and a side of power panel 2 is resisted against on the guide vane end stop 35, and opposite side is installed in the high-order buckle 34, and second securing member 6 passes installing hole 22 power panel 2 is fixed on the high-order screw post 34.
In the present embodiment, described first securing member 4 and second securing member 6 are respectively screw.High-order screw post 34 shafts of described key support 3 are longer, and the shaft of low level screw post 33 is shorter, by to the adjustment of length difference between shaft design, can make distance between display panel 1 and the power panel 2 reach the requirement of electric clearance.
