Description

A kind of electromagnetic shielding box
Technical field
This utility model belongs to shielded box field, is specifically related to a kind of electromagnetic shielding box.
Background technology
The development of electronic technology has driven the continuous expansion of electronic industry, various electronic equipments especially essence point electronic equipment, is affected the biggest by electromagnetic environment;Electromagnetic interference (Electromagnetic Interference, EMI) it is interference cable signal and reduces the electronic noise of signal integrity, along with mankind's footprint is entered into ocean perilous peak, electromagnetic interference has penetrated into every nook and cranny, the world;The electromagnetic interference shield in field is also a problem faced by we often need.
Utility model content
Technical problem to be solved in the utility model is: for the electromagnetic interference in field, it is provided that the electromagnetic shielding box of a kind of applicable wild environment.
Technical solution adopted in the utility model is:
A kind of electromagnetic shielding box, including lid, base plate, support;Wherein lid is the metal case not having bottom surface, and box body cross section is rectangular;Lid top is provided with handle, and the left and right side of lid is respectively provided with fan mouth, and fan mouth installs fan, and one is used for air intake, and one is used for air draft, and closes with gauze screen, arranges rain cover outside gauze screen;Lower edge, lid side arranges groove;Base plate is rectangular metal plate, hinge be connected with edge under lid one side, and base plate arranges wire harness hole, and base plate four circle Monday arranges the tongue of the fit depressions with lid;After lid closes with base plate, snap close lock.
Further, the edge, the left and right sides of described base plate arranges base plate screw, and support is right angle spider form, a right-angle side arranges the support screw corresponding with base plate screw, is attached by bolt.
Further, the fan mouth of described lid left and right sides is not on a same horizontal plane.
Further, using groove to match with tongue between lid with base plate at Guan Bi, described depth of groove is more than the tongue degree of depth, during cooperation, pads conductive rubber in groove.
Further, the top end face of described lid is " roof " shape structure.
The beneficial effects of the utility model are: the shielded box of a kind of simple in construction, may be used for field complex environment.Fan can make described electromagnetic shielding box produce good heat radiation, and described box body is whole as lid, when raising, can be convenient carry out associative operation;Lid and base plate use tongue and groove to be attached, and sealing effectiveness is excellent;Cover with the rain cover that opening direction is downward outside fan, the wind and rain being possible to prevent in wild environment.
Further, when fan is not at same level, have more preferable radiating effect;Arrange supporting structure to facilitate and install in the wild, it is possible to prevent the invasion and attack of strong wind;Tongue and groove arranges conductive rubber, adds sealing effectiveness;" roof " shape structure of top cover, can facilitate the excretion of rainwater, reduce the hydrops of rainwater, dew simultaneously, prevent the corrosion that hydrops causes.

Fig. 1 is the broken away view of described a kind of electromagnetic shielding box;
Fig. 2 is the groove connection section detail view of described a kind of electromagnetic shielding box;
Fig. 3 is the Guan Bi schematic diagram of described a kind of electromagnetic shielding box;
In figure, 1-lid, 2-base plate, 3-support, 11-handle, 12-fan mouth, 13-fan, 14-gauze screen, 15-groove, 16-conductive rubber, 17-snap close, 18-rain cover, 21-hinge, 22-wire harness hole, 23-base plate screw, 24-tongue, 31-support screw.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.
A kind of electromagnetic shielding box as shown in Figure 1, Figure 2, Figure 3 shows, including lid 1, base plate 2, support 3;Wherein lid 1 is the metal case not having bottom surface, and box body cross section is rectangular, and box body top end face is in " roof " shape structure, it is possible to effectively drain rainwater and dew, prevents the accumulation of rain and dew.Lid 1 top is provided with handle 11, and the left and right side of lid 1 is respectively provided with fan mouth 12, and fan mouth 12 installs fan 13, one is used for air intake, and one is used for air draft, and two fan mouths 12 are not in same level, one side on the upper side, a partial below, be conducive to preferably heat radiation;And close with gauze screen 14, rain cover 18 is set outside gauze screen 14;Lower edge, lid 1 side arranges groove 15;Base plate 2 is rectangular metal plate, it is connected with edge under lid 1 one side by hinge 21, wire harness hole 22 is set on base plate 2, base plate 2 four circle Monday arranges the tongue 24 matched with the groove 15 of lid 1, groove 15 degree of depth is more than the height of tongue 24, when groove 15 coordinates with tongue 24, it is encased inside with conductive rubber 16, by increasing capacitance it is possible to increase the sealing of electromagnetic shielding box.After lid 1 closes with base plate 2, snap close 17 lock.When needs are fixed on field, it is possible to use support 3, being connected with base plate screw 23 and support screw 31, support 3 can be fixed on the fixed support in field, carries out the fixing of field easily.
Described a kind of electromagnetic shielding box, compared with tradition shielded box, has the technical characteristic of multinomial adaptation wild environment, is the electromagnetic shielding box in the field of a kind of practicality.
