Abstract
The invention relates to an analog circuit box type plug-in system structure which is characterized in that a locking strip of an analog circuit box type plug-in is tightly pressed at the bottom of the slot of a slot board, so that the heat radiation plane of the analog circuit box type plug-in and the upper surface of a heat exchanger are tightly adhered to a contact plane. The analog circuit box type plug-in adopts the structure that the locking strip is fixed on one side wall of a box body through a screw; the heat radiation plane is arranged on the other opposite side wall; a floating type electric coupler arranged in a blind insertion manner is installed on one adjacent side; and a panel is arranged at the other adjacent side. According to the analog circuit box type plug-in system structure, the electric connector between the analog circuit box type plug-in and a mother board adopts the floating structure type, the locking strip installed on the analog circuit box type plug-in is tightly pressed at the bottom of the slot board, and the heat radiation plane tightly presses on the surface of an environment control system heat radiator (also called as cold plate). After the structure is adopted, the good single-side heat radiation is realized with a plug-pull function and an electromagnetic shielding function; and the analog circuit box type plug-in system structure can be applied to fields of military and civil products with higher requirements on both the electromagnetic shielding property and the single-side heat radiation of the plug-in.
Description
Technical field
The invention belongs to machinery, heat and three technical fields of electromagnetism, relate to one-sided good heat radiating and possess the electronic equipment of plug function and electro-magnetic screen function, be specifically related to a kind of analog circuit boxlike plug-in unit system configuration.
Background technology
Traditional analog circuit box structure by heat conduction and heat radiation has two kinds of versions: traditional boxlike fixed structure (schematic diagram is seen Fig. 1) and traditional boxlike dongle configuration (schematic diagram is seen Fig. 2).
Traditional boxlike fixed structure is easily realized one-sided good heat radiating, but it requires system that correspondingly " opening character " arranged.More when number of modules, and the width of each module is when wider again, if adopt traditional boxlike fixed structure, designed system is very heavy, and is not easy to maintenance.
Traditional good, compact conformation of boxlike dongle configuration maintenanceability, but it is by bilateral locking strip side pressure socket sidewalls (making the non-installed surface of box body guide rail be close to another socket sidewalls) heat to be conducted to subrack, and heat is taken away by free convection or forced convection in the subrack outside.The problem that exists is when environmental control system requires the one-sided heat radiation of plug-in unit, traditional boxlike dongle configuration and heat exchanger contact area little (one-sided), and contact heat resistance is large, and heat conduction efficiency is not high.
Electronic equipment is to high density, miniaturization development at present, and unit density of heat flow rate value constantly increases in the electronic equipment, and temperature is also more and more higher, and traditional box structure can't satisfy one-sided heat radiation and possess the plug functional design requirements.
Summary of the invention
The technical problem that solves
For fear of the deficiencies in the prior art part, the present invention proposes a kind of analog circuit boxlike plug-in unit system configuration, has proposed the one-sided side pressure scheme of locking strip, is used for solving one-sided good heat radiating and possessing plug function technical problem.
Technical scheme
A kind of analog circuit boxlike plug-in unit system configuration is characterized in that comprising analog circuit boxlike plug-in unit 7, slot board 15, heat exchanger 16 and motherboard 17; Described analog circuit boxlike plug-in unit 7 comprises locking strip 8, box body 9, pattern electric connector 11 and conductive seal pad 12 float; Locking strip 8 is fixed by screws on the sidewall of box body 9, and another relative sidewall is provided with radiating surface 14, and an adjacent side is installed the unsteady pattern electric connector 11 of blindmate, and opposite side is adjacent to be panel; Analog circuit boxlike plug-in unit 7 and slot board 15, the annexation of heat exchanger 16 and motherboard 17 is: the locking strip 8 of analog circuit boxlike plug-in unit 7 is pressed on the slot bottom of slot board 15, makes the radiating surface of analog circuit boxlike plug-in unit 7 and heat exchanger 16 upper surfaces be close to contact-making surface 20.
Between unsteady pattern electric connector 11 and box body 9, be provided with conductive seal pad 12.
Beneficial effect
A kind of analog circuit boxlike plug-in unit system configuration that the present invention proposes, for have plug functional simulation circuit module when relying on the one-sided side pressure socket sidewalls of locking strip structure contact area less, thereby the solution that causes the relatively poor problem of heat dispersion to propose.Electric connector is selected the floating structure pattern between analog circuit boxlike plug-in unit of the present invention and motherboard, and locking strip mounted thereto compresses the slot board bottom, and its radiating surface presses environmental control system heat exchanger (also claiming cold drawing) surface.This structure realizes one-sided good heat radiating and possesses plug function and electro-magnetic screen function.Can be applied to dual-use product scope that electromagnetic wave shielding and the one-sided thermal diffusivity of plug-in unit are all had relatively high expectations.
Compare with traditional analog module structure by heat conduction and heat radiation, boxlike dongle configuration of the present invention has following features:
1, contact with the heat exchanger large tracts of land of environmental control system, contact heat resistance is little, and heat conduction efficiency is high;
2, the analog circuit boxlike plug-in unit system configuration of the present invention's proposition has the plug function;
Though 3 and motherboard between electric connector select the floating structure pattern, because the conductive seal pad is installed, still have electro-magnetic screen function.
