Abstract
An electronic shield box comprises a box cover and a box bottom, wherein a circuit board is contained in the mounting box which is provided with a communication end for electrically connecting an external circuit with the circuit board. The electronic shield box is characterized in that a rotary connecting shaft is arranged between the box cover and the box bottom, the communication end which is a slot on the connecting shaft is arranged on the connecting shaft and used for containing an interface end of the circuit board, and support posts are arranged at the box bottom for supporting the circuit board. The electronic shield box is simple in structure, practical and resistant to electromagnetic interference, mechanical damage and the like.
Description
Technical field
The utility model relates to circuit board mounting structure, and it can avoid extraneous infringement.
Background technology
Printed circuit board (PCB) is very common in the modern electronic product, and fitting printed circuit board in electronic instrument or equipment is generally with screw or socket and track-type facilities installation.Adopt the screw fitting printed circuit board, install, dismantle all inconveniences, and circuit board needs fixing threaded hole accordingly, this design to circuit board, making and follow-up normal use have all proposed restriction, can't reduce cost, improve the efficient of electrical work.And adopt the general operation of socket fitting printed circuit board convenient, but the bigger printed circuit board (PCB) of single-block area is installed in the electronic equipment casing, then, can only adopt screw to fix because the restriction of the space structure of casing itself generally is difficult to adopt socket and track-type facilities to be installed.Such erecting device is installed, the dismounting circuit board is all inconvenient.
Simultaneously, prior art as shown in Figure 1, electronic component 12 open grounds are arranged on the circuit board body 11, can often run into the problem of electromagnetic interference in the circuit board use of this structure, the occasion of some accurate purposes particularly, the influence of electromagnetic interference is more obvious.Therefore press for the needs that a kind of energy shield electromagnetic interference circuit board satisfy reality.Simultaneously circuit board in the installation process, owing to need the plug debugging, therefore may exist electronic component to suffer extraneous collision at the scene, for example collision of adjacent circuit plate, and perhaps circuit board is installed the collision of casing.More than these machineries, electronics infringement all may cause expendable infringement between electronic component and the circuit board, influence is worked normally.
The utility model content
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of electronic shield case, it has at the bottom of case lid and the case, described circuit board is contained in the described install bin, described install bin has the communication terminal that external circuit is linked to each other with described circuit board electrical equipment, it is characterized in that: have the axle of being rotatably connected between at the bottom of described case lid and the case, described communication terminal is located on the described connecting axle; Described communication terminal is the slot of being located on the described connecting axle, to hold the interface end of described circuit board; Has pillar at the bottom of the described case, to support described circuit board.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: electronic shield case outer setting of the present utility model has install bin, and is preferably made by metal material, thereby can shield the electromagnetic interference of big portion outside.This programme is simple in structure, practical, can avoid the dual infringement of electronics and machinery.

Fig. 2 is the schematic perspective view of install bin of the present utility model;
Fig. 3 is the part schematic diagram of decomposition of the present utility model;
Fig. 4 is the schematic diagram under the closed state of the present utility model;
Fig. 5 is the cutaway view of safety circuit plate of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As Fig. 2 and shown in Figure 4, the utility model provides a kind of electronic shield case 1, it has at the bottom of case lid 7 and the case 2, described circuit board is contained in the described install bin, described install bin 1 has the communication terminal that external circuit is linked to each other with described circuit board electrical equipment, have the axle 3 that is rotatably connected between at the bottom of described case lid and the case, described communication terminal is located on the described connecting axle 3; In addition, in the utility model, also have pillar 4, to support described circuit board, described pillar has three at least, and is triangularly arranged.
An improvement of this practical information as shown in Figure 3, described communication terminal are the slot of being located on the described connecting axle 5, to hold the interface end of described circuit board.
Be illustrated in figure 5 as an improvement of the present utility model, the metal cover 30 that comprises circuit board body 10, electronic component 20, makes by metal material, and it has the insulation outer cover; Described electronic component 20 is arranged on the circuit board body 10; Described metal cover 30 covers electronic component 20.In addition, the inside of described metal cover 30 is provided with pillar 40, is used for supporting electronic component 200, and described pillar 40 is connected described electronic component 20 with metal cover 30 insulation.Because the utilization of technique scheme, the utility model compared with prior art has following advantage: circuit board of the present utility model, outer setting at electronic component has capping, and described capping is made by metal material, thereby can shield the electromagnetic interference of big portion outside.The inside of capping simultaneously is provided with pillar, can support electronic component, and this programme is simple in structure, practical.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection range of accompanying Claim of the present invention.
