Abstract
The utility model discloses a can accurate shell structure who injects circuit board position, including procapsid and back casing, procapsid and back casing lock joint together, accommodation space is formed between the two, preceding shells inner wall on be equipped with the rib more than two or two, rib more than two or two relative and establish, forms the space that the circuit board was impressed between the rib more than two or two. Because the utility model discloses being equipped with on the casing inside wall and further being provided with rib structure tiny, that play further limiting displacement on simple limit structure's the basis, the rib is the minimum edge space that can not arrange components and parts in busy line edge, and other spaces on can not the busy line board make the utility model has the advantages of simple structure, convenient assembling can gain the effect high to circuit board positioning accuracy.
Description
Technical field
This utility model relates to a kind of electric equipment, particularly relates to a kind of shell structure that can accurately limit wiring board position.
Background technology
In existing electrical equipment, when circuit board module is laid in the housing, generally there is following several method: use screws to pin circuit board module；Wiring board is caught on the snap fit on housing；Circuit board module is directly placed in housing by modes such as the simple position limiting structure of case inside wall are limited.The subject matter existed is: when fixing with screw, wiring board must leaving hole, the surrounding in hole can not arrange components and parts, and it is unfavorable that wiring board is pursued compact size by this；Adopt this structure of snap fit, then mould structure is complicated, relatively costly；Utilizing on case inside wall spacing, owing to needing to leave, appropriate gap carries out wiring board puts into installation, will appear from gap, if element is obviously unfavorable when need to have a higher relative position requirement with other part on housing on wiring board.
Summary of the invention
The purpose of this utility model is in that the shell structure that can accurately limit wiring board position providing a kind of simple in construction, easy to assembly, assembly precision is high.
For achieving the above object, technical solution of the present utility model is:
This utility model is a kind of shell structure that can accurately limit wiring board position, including procapsid and back casing；Described procapsid and back casing snap together, and form accommodation space between；Described procapsid inwall is provided with two or more rib, and two or more ribs set relatively, forms the space of wiring board press-in between two or more ribs.
Described rib has two, it is rectangular in shape, the right-angle side of two ribs sets and is perpendicular to the internal face of procapsid relatively, the dual-side of wiring board acts against on the right-angle side of two ribs respectively, distance between wiring board dual-side is more than the distance between the right-angle side of two ribs so that wiring board and two ribs form interference fit.
After adopting such scheme, it is further provided with tiny, to play further position-limiting action bead structures owing to this utility model is provided with on the basis of simple position limiting structure on case inside wall, rib is the rim space that can not arrange components and parts that busy line edge is minimum, will not other space on busy line plate so that this utility model has simple in construction, easy to assembly and can obtain the effect that wiring board positioning precision is high.
Below in conjunction with the drawings and specific embodiments, this utility model is further described.

Detailed description of the invention
As shown in Figure 1-Figure 3, this utility model is a kind of shell structure that can accurately limit wiring board position, including procapsid 1 and back casing 2.
Described procapsid 1 snaps together with back casing 2, forms accommodation space between.
Described procapsid 1 inwall is provided with two ribs 11,12(as shown in Figure 4), it is rectangular in shape, the right-angle side 111,121 of two ribs 11,12 sets and is perpendicular to the internal face of procapsid 1 relatively.The space of wiring board 10 press-in is formed between the right-angle side 111,121 of two ribs 11,12.
During assembling, the dual-side of wiring board 10 acts against on the right-angle side 111,121 of two ribs 11,12 respectively, distance between wiring board 10 dual-side is more than the distance between the right-angle side 111,121 of two ribs 11,12 so that wiring board 10 and two ribs 11,12 form interference fit.
Structural principle of the present utility model:
The utility model proposes the limiting structure of another uniqueness, requirement feature according to product, wiring board 10 size of components small size is light, but require wiring board 10 high in housing (being made up of procapsid 1 and back casing 2) inner position precision and position is fixed, the part relative position being matched therewith is fixed, and is namely further provided with tiny rib 11,12 spacing further on the simple position limiting structure on procapsid 1 medial wall.Due to the small-sized of rib 11,12 and the lower section being arranged on procapsid 1 inwall position limiting structure, wiring board 10 assembly can put into housing easily.Rib 11,12 is just touched when wiring board 10 is in place soon, owing to rib 11,12 is small-sized and only small with wiring board 10 interference fit partial volume, under the pressure being subject to wiring board 10, the rib 11,12 of plastics can deform, and is filled with the gap of wiring board 10 assembly and inner walls.So wiring board 10 assembly is in place afterwards and basic gapless between rib 11,12, limits wiring board 10 assembly well but wiring board 10 will not be caused very big stress, can accurately wiring board 10 be carried out spacing.Owing to case material is thermoplastic, rib 11,12 is squeezed deformation without producing plastics smalls.
It should be noted that the shape of rib can also be rectangle, other shape such as square, its number also can be determined according to needs.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence namely made according to this utility model claim and description changes and modifies, and all should still belong in the scope that this utility model patent contains.
