Embodiment

Following structure drawings and Examples are further described the utility model.

As shown in Figure 4.

It links to each other a kind of modular unit box structure with lid 7 (as Fig. 2) and forms by having box body 6 (as Fig. 1) at the bottom of the box, on the downside of box body 6, be provided with plug breach 2 and mistake proofing pin-and-hole 5, respectively be provided with the installation groove 1 of an installation elasticity carrying handle 8 in the upper surface both sides of box body 6, on two the side tops adjacent mounting flange 4 is installed respectively with upper surface, captive screw 12 is installed on the mounting flange 4, on parallel with direction of insertion at box body one or two sides guided way 3 is installed.On the inner surface of lid 7, be provided with along what its circumferential perimeter was arranged and be used to insert the medial flange that plays the shield gasket effect 9 in the box body 6.Described elasticity carrying handle 8 is journaled on the bearing pin 10, and torsion spring 11 is installed on the bearing pin 10, and an end of torsion spring 11 and the side of box body 6 offset, and another side and elasticity carrying handle 8 offset.

For the ease of producing in batches, reduce cost, box body 6 of the present utility model adopts the metal crimp foundry goods to make.Box body 6 designs have carrying handle that structural elements such as groove 1, plug breach 2, guided way 3, mounting flange 4, mistake proofing pin-and-hole 5 are installed.It is the position that elasticity carrying handle 8 is installed that groove 1 is installed, and the mounting flange 4 of the both sides captive screw 12 of can packing into after unit box of the present utility model inserts motherboard, plays the effect of fixed bin body simultaneously; Plug breach 2 is reserved the position to the external connector of printed board in the box body, and its openings of sizes is decided according to the selected plug of plate; Guided way 3 be box body in installation process be fixed on supporting bracket 13 (see figure 3)s on locator slide cooperated the guide-localization effect; Mistake proofing pin-and-hole 5 is in case stop element box insertion motherboard wrong plug position is used, and the position, hole of different types of unit box has nothing in common with each other, and is corresponding with the position, hole of motherboard after pin is gone in riveting, improves the fault-tolerant ability that unit box uses.The three-dimensional exploded view of unit box as shown in Figure 4.

The utility model unit lid 7 equally also adopts the metal crimp foundry goods to make.Lid design in unit has screw to immerse oneself in concave plane 14 and medial flange 9, and its outline drawing as shown in Figure 2.Concave plane 14 is to be convenient to make trip bolt to screw in the surface that head of screw behind the screw is not higher than box body 6, plays and saves installing space and beauty function.After unit lid 7 and unit box body 6 fasten, medial flange 9 has overlapping preferably coincideing with unit box body 6 inboards, and unit lid 7 has all been done the electric conductive oxidation surface treatment with unit box body 6, therefore the shield gasket effect is played in inner printed board, if further improve the effectiveness of frame ground and overlap joint, the required annexes of electromagnetic shielding such as shielding finger can also be installed easily on the medial flange 9.Therefore, the utility model has the effect of good electromagnetic shielding.

Elasticity carrying handle 8 of the present utility model has two, is positioned at the centre of both sides, unit box body 6 top mounting flange 4, and it is installed on the box body 6 by bearing pin 10 and torsion spring 11, and torsion spring 11 plays plug power-assisted and elastic reset effect.Its schematic diagram as shown in Figure 3.Wherein torsion spring 11 embeds in the installation groove 1 of carrying handle 8 and box body 6, by bearing pin 10 fixing and supports.Carrying handle was in initial bit after unit box was installed in the electronic equipment, and this moment, carrying handle outline and box body outline coincide, and the plug of unit box is just inserting in the socket of motherboard (big base plate).When box body need rise when pulling out, at first unscrew out the captive screw of fastening unit box, rotate elasticity carrying handle 8 then, be rotation axis with bearing pin 10, under the effect of lever principle, box body 6 has upwards slided and has pulled out.This moment, the limitation of movement of box body 6 can only move up and down by vertical direction, protects the spininess plug not impaired by vertical plug automatically because the guided way 3 of unit box is in the locator slide.Taken into full account man-machine factor in the carrying handle configuration design, making has living space between carrying handle and the box body allows finger insert, institute so that whole to pull out process very light, just make that also the utility model often need in the equipment of quick maintain and replace modular cartridge to be specially adapted to.

On the mounting flange 4 of the present utility model many captive screw 12 are installed, guarantee the intensity and the ease of use of installing.Be respectively equipped with 4 captive screw 12 at unit box top corner location, be used for and supporting bracket 13 fixed bin bodies.Every installing hole of unit lid 7 also is respectively equipped with captive screw 15, is used for fixing lid 7 and box body 6.Captive screw also makes unit box be not easy to lose securing member, handled easily user simultaneously in debugging at ordinary times, keeping in repair.

As shown in Figure 1, 2, the utility model makes standardised generic production to realize owing to adopt the manufacturing process of being convenient to produce in enormous quantities.At present because the develop rapidly of radio communication, product design based on bus architecture is more and more, emerge a large amount of motherboard plug-in card class formation electronic communication equipments, and improving constantly along with device integration, electromagnetic interference problem between the equipment, between the device interior integrated circuit board is also more and more serious, and the utility model can solve these contradiction.Fit electric conductivity preferred metal material that adopts itself, ground connection is provided with the slit that flange can reduce box body as much as possible by the unit lid preferably, reduces the electromagnetic leakage between each plate and crosstalks mutually.By the jamproof design of rational printed board circuit, make modular cartridge that good Electro Magnetic Compatibility can be arranged again, satisfy the requirement of the anti-electromagnetic interference of equipment.Because part is few, good assembling process, installation process are very simple.Printed wiring board can be fastening with unit box by screw; Snap in carrying handle and the unit box body groove by direction changeing a spring during assembling of elasticity carrying handle, screwing in bearing pin can fix; The installation of captive screw is as long as screw in corresponding installing hole respectively by kind; Anti-plug mispointing pin also only needs a riveting to go into box body to get final product.Labeling can also be printed or paste in the table plane on box body in addition, can identify management easy to use to unit box.Can greatly reduce the mixed and disorderly situation of electronic communication equipment internal wiring in the past so that device interior is neatly unified.Therefore the utility model can be widely used in the communication electronic equipment that standardization and generalization have relatively high expectations.
