Further, said interface connector comprises signal input port, signal output port or communication interface.
Further, be provided with power module in the said cabinet, because electrical specification; Power module is always isolated with main circuit board, and therefore, said power module is arranged in the protuberance that does not cave in the middle of the rear panel of said cabinet; The area of dissipation of power supply increases greatly, helps power supply heat sinking.
Further, the rear panel of said cabinet is X type structure, so that device structure is more firm.
Further, the rear panel of the cabinet of the said X of being type structure is provided with a lockhole, with fixing cabinet easily, guarantees the equipment property safety.
The utility model is compared with existing product, has following actively useful effect:
1, the utility model makes interface module be integrated on the main circuit board, helps the assembling of circuit design and structure.
2, the utility model is directly drawn the interface splicing ear from circuit main board, saves the complicated circuitry cabling, reduces the phase mutual interference between circuit.
3, the utility model significantly reduces circuit module, has reduced design and production cost, and the device structure size decreases is more suitable for desktop application simultaneously.
4, the utility model makes the distribution of instrument internal part compacter, reduces overall volume, and improves efficiency of assembling effectively, and through verification experimental verification, the reliable installation degree meets the demands.
5, the utility model rear panel is the design of X type, makes structure compactness, safety and firmness more.
6, the utility model makes mould structure simpler, has further reduced cost.
