Abstract
A novel circuit board structure is provided with a box cover and a box base and is accommodated in a mounting box. The mounting box is provided with a communication terminal which connects an external circuit and circuit board electrical appliances. The novel circuit board structure is characterized in that a rotary connecting shaft is arranged between the box cover and the box base, and the communication terminal is arranged on the connecting shaft. The circuit board comprises a circuit board body, electronic components and a metal cover, wherein the electronic components are arranged on the circuit board body, the metal cover covers the electronic components, a post for supporting the electronic components is arranged inside the metal cover, and the electronic components are in insulation connection with the metal cover through the post. The novel circuit board structure is simple in structure, practical and capable of resisting disturbance and damage of electromagnet, machines 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 new-type circuit plate structure, it has at the bottom of lid and the box, described circuit board is contained in the described mounting box, described mounting box 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 lid and the box, described communication terminal is located on the described connecting axle; Described circuit board comprises circuit board body, electronic component and metal cover; Described electronic component is arranged on the circuit board body; Described metal cover covers electronic component; The inside of described metal cover is provided with the pillar that supports described electronic component, and described pillar is connected described electronic component with the metal cover insulation.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: new-type circuit plate structure outer setting of the present utility model has mounting box, 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.
Description of drawings
Fig. 1 is the schematic diagram of existing traditional circuit plate structure;
Fig. 2 is the schematic perspective view of mounting box of the present utility model;
Fig. 3 is the part schematic diagram of decomposition of the present utility model;
Fig. 4 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 shown in Figure 2, the utility model provides a kind of new-type circuit plate structure 1, it has at the bottom of lid 7 and the box 2, described circuit board is contained in the described mounting box, described mounting box 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 lid and the box, described communication terminal is located on the described connecting axle 3.In addition, in the utility model, have pillar 4 at the bottom of the described box, described pillar 4 has three and be triangularly arranged at least, to support described circuit board.
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 4 as an improvement of the present utility model, comprise circuit board body 10, electronic component 20, by the metal cover 30 that metal material is made, preferably 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; 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.
