Abstract
The utility model discloses an instrument box structure in the type of an inner container. The instrument box structure in the type of the inner container includes an inverted-U-shaped shell, a U-shaped inner container, a front face board and a rear face board. A front face and a rear face of the U-shaped inner container are connected with the front face board and the rear face board fixedly. The bottom face of the U-shaped inner container is put into the inverted-U-shaped shell along two side edges of the bottom part of the inverted-U-shaped shell. The rear face board is connected with the shell fixedly. An L-shaped shielding separating board is arranged on the bottom face of the U-shaped inner container and divides the bottom face of the U-shaped inner container into two shielding areas. By adopting the structure of the inner container and arranging the shielding areas, electromagnetic interference between an inner main circuit board and a switch power source as well as between the internal and the external is avoided effectively, thereby realizing a good shielding effect and realizing comparatively high precision requirements for products. Besides, the instrument box structure in the type of the inner container facilitates the replacement of the front face board, the rear face board and the shell, especially the replacement of the front face board since front face boards are generally printed with product specification information of an instrument. And the universal inner container can match the front face boards of different specifications flexibly and conveniently, thereby realizing an aim of facilitating exchange and guaranteeing the timely delivery after the instrument is ordered.
Description
Technical field
The utility model relates to a kind of instrument box structure, especially relates to a kind of liner type instrument box structure.
Background technology
At present, most instruments or adopt simple sheet metal structural, by several independently the mode of metallic plate splicing form the outer cabinet of instrument, because of processing and rigging error, can there be inevitably the gap between each part, instrument internal is just passed through gap phase mutual interference with extraneous electromagnetic signal, causes instrument shield effectiveness variation, thereby can not reach higher shielding properties index; Or in order to satisfy the complicated structure of shield effectiveness employing, a kind of instrument is comprised of the dozens of parts possibly, causes apparatus installation and dismounting difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of liner type instrument box structure, thereby effectively avoids between instrument internal main circuit board and the Switching Power Supply and instrument internal and extraneous electromagnetic interference; In addition, because most of element is positioned in the inner bag, can change easily front and back panels and the housing of instrument.
The technical scheme that the utility model adopts is:
Comprise inverted U-shaped housing, U-shaped inner bag, front panel and rear board; Forward and backward of the U-shaped inner bag is fixedly connected with front panel, rear board respectively, packs into along the two bottom sides limit of inverted U-shaped housing in the inverted U-shaped housing in U-shaped inner bag bottom surface, and rear board is fixedly connected with housing.
Described U-shaped inner bag bottom surface is provided with L shaped shielded partitions, and U-shaped inner bag bottom surface is separated into two blind zones.
Described inverted U-shaped housing, U-shaped inner bag, front panel and rear panel material are metal material.
The useful effect that the utlity model has is:
The inner-tube structure that the utility model adopts, for block of metal material pressing and bending is made, and spot welding shielded partitions between main circuit board and Switching Power Supply, has good shield effectiveness, can effectively avoid between instrument internal main circuit board and the Switching Power Supply and instrument internal and extraneous electromagnetic interference, thereby make instrument reach good shield effectiveness, realized the degree of precision requirement of product.In addition, the liner type apparatus structure is convenient to the replacing of front and back panels and housing, the particularly replacing of front panel, because front panel is printed with the product type information of instrument more, and the general inner bag front panel of adapted different model flexibly and easily reaches convenient transposing, guarantees the in time purpose of delivery of instrument sales.
Description of drawings
Fig. 1 is structure exploded perspective view of the present utility model.
Fig. 2 is the outline drawing after the utility model assembling.
Among the figure: 1. front panel, 2.U shape inner bag, 3. shielded partitions, 4. rear board, 5. inverted U-shaped housing.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises inverted U-shaped housing 5, U-shaped inner bag 2, front panel 1 and rear board 4; Forward and backward of U-shaped inner bag 2 is fixedly connected with front panel 1, rear board 4 respectively, packs into along the two bottom sides limit of inverted U-shaped housing 5 in the inverted U-shaped housing 5 in U-shaped inner bag 2 bottom surfaces, and rear board 4 is fixedly connected with housing 5.
U-shaped inner bag 2 bottom surfaces are provided with L shaped shielded partitions 3, and U-shaped inner bag 2 bottom surfaces are separated into two blind zones.
Inverted U-shaped housing 5, U-shaped inner bag 2, front panel 1 and rear board 4 materials are metal material.
The both sides of U-shaped inner bag 2 are fixedly connected with front panel 1, rear board 4 by screw respectively.
Rear board 4 is fixedly connected with inverted U-shaped housing 5 by screw.
The both sides of inverted U-shaped housing 5 are provided with louvre, and the position of the electric component radiator fan of installing in the 2 liang of mother rib lateral rotundums in the position of louvre and U-shaped inner bag is corresponding.
Most of electric components such as main circuit board and Switching Power Supply are installed in U-shaped inner bag 2, the 3 pairs of main circuit board parts of shielded partitions and the Switching Power Supply that are welded in the U-shaped inner bag 2 by point partly shield, shielded partitions 3 has good shield effectiveness, can effectively avoid the electromagnetic interference between instrument internal main circuit board and the Switching Power Supply.
U-shaped inner bag 2 is made for block of metal material pressing and bending, bottom in two blind zones that shielded partitions 3 is separated is equipped with Self-Clinching Standoffs, the Self-Clinching Standoffs of two blind zones is respectively applied to fixedly main circuit board and Switching Power Supply, make main circuit board bottom leg leave base plate avoiding short circuit, and also can be dispelled the heat well in the bottom of Switching Power Supply.
Front panel 1 adopts metal weldedstructure, and the information such as product type of instrument have been printed in the front.
Rear board 4 adopts the metallic plate pressing and bending to make, and printed the information of switch, supply socket, each element of earthing rod.The elements such as switch, supply socket, earthing rod are installed on the rear board 4, when all elements and main circuit board with after Switching Power Supply is connected, be inserted in the back inverted U-shaped housing 5, with screw that rear board 4 and inverted U-shaped housing 5 is fixing with U-shaped inner bag 2 at last.
As shown in Figure 2, inverted U-shaped housing 5 adopts block of metal material pressing and bending to make, be installed in U-shaped inner bag 2 outsides, both sides and the end face of U-shaped inner bag 2 have been covered, add front and back panels to the shield effectiveness of the forward and backward both sides of the utility model casing and the U-shaped inner bag shield effectiveness to the utility model tank floor, thereby effectively stop casing instrument internal and extraneous electromagnetic interference.
