Abstract
The invention discloses a grounding structure which comprises a housing and a metal support positioned in the housing, and at least one guide groove block connected with the metal support is further arranged in the housing; a heat radiation hole and a guide groove with a built-in fixing clamp are arranged on the guide groove block, and the guide groove penetrates the upper surface of the guide groove block along the axial direction of the guide groove block; a U-shaped clamping piece is arranged on the fixing clamp, two arms of the clamping piece are in shaped like arcs and protrude oppositely inwards, and the bottom part of the clamping piece is jointed with the metal support; and the metal support is jointed with the end of the guide groove block, and two ends of the metal support are fixed on the inner sides of the housing of a device. The grounding structure is simple, and can avoid the situation of leftward and rightward deviation of installation of a circuit board caused by deviation of the welding assembly process of the guide groove of the circuit board, lead the heat radiation performance to be good and lead the grounding performance to be stable.
Description
Technical field
The present invention relates to a kind of ground structure, refer to a kind of ground structure of industrial control equipment especially.
Background technology
General industrial control appliance product, its circuit board pushes by the guide-track groove that is dispersed in device interior, tightens the installation nut on the circuit board then, and it is fully contacted with aluminum strip, and then fuse with device housings, be connected with the earth by earthing of casing terminal at last.
This ground structure, when circuit board is pushed by guide-track groove, can make about circuit board because of the deviation of guide-track groove welding assembly technology and be offset, if this equipment has a plurality of circuit boards to need parallel arranged, then can cause deviation to cause that other circuit boards can not fit into the situation of equipment together because of a guide-track groove.
Simultaneously, the installation nut on the circuit board also can transport, assemble improper or the engineering site environmental impact because of equipment, and produces the phenomenon of loose or dislocation, causes circuit board not form effective general safety ground connection with the equipment miscellaneous part.
Summary of the invention
Technical problem to be solved by this invention be avoid general circuit plate guide groove because of welding assembly technology deviation circuit board is installed about skew, and the general circuit plate because of hold-down nut loosening can not with the equipment abundant ground connection that fuses.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of ground structure, comprise shell and the metallic support that is positioned at shell, and also be provided with at least one guide groove piece that links to each other with metallic support in the shell; Described guide groove piece is provided with the guide groove of louvre and built-in geometrical clamp, and guide groove runs through guide groove piece upper surface along guide groove piece axial direction; Described geometrical clamp is provided with U type intermediate plate, and intermediate plate two arms are arc and relatively to inner process, fits with metallic support in the intermediate plate bottom; Fit in described metallic support and guide groove piece termination, and the device housings inboard is fixed at two ends.
During use, can select the guide groove piece of suitable dimension for use, make its discharging arranged side by side, circuit board is pushed along guide groove, circuit board accurately can be located according to the width of equipment; Louvre on the guide groove piece helps heat radiation; Two arms to inner process on the U type intermediate plate can tightly be clamped the bonding jumper at circuit board two ends, simultaneously, bottom with intermediate plate props up the metallic support that device interior is used for fixing the guide groove piece, and then is connected as a single entity with device housings, is connected with the earth by earthing of casing terminal at last.
Be the further grounding function of reinforcement equipment, described metallic support is a T type sheet metal, and guide groove piece termination also is provided with the slot with the T type afterbody coupling of metallic support, and slot communicates with guide groove and is positioned at below the guide groove; Also be provided with a contact chip on the described geometrical clamp, it links to each other with intermediate plate bottom and is positioned at the intermediate plate bottom, and described contact chip also is an arc and to lower process, the applying of the T type afterbody of contact chip prominence and metallic support.Arc contact chip to lower process can fully prop up metallic support, has guaranteed that the electric conductivity between metallic support and the intermediate plate is stable.
Advantage of the present invention is: simple in structure, and avoided general circuit plate guide groove to make the situation that is offset about the circuit board installation, perfect heat-dissipating, ground connection stable performance because of welding assembly technology deviation.
