Description

A kind of novel standard cabinet

Technical field

The utility model is related to electronics, technical field of communication equipment, more particularly to a kind of novel standard cabinet.

Background technology

Cabinet refers to one kind in electronics, communication equipment, and the dress of support, decoration, protective effect can be played to component It sets, forms an intensive entirety；Its solid shell protects the component in it, and energy is against pressure, protecting against shock, prevents Dirt, and it can also put anti-electromagnetic interference, the function of radiation to good use, play a part of to shield electromagnetic radiation.

Existing metal plate standard PC case technical solution mainly has following two situation：One is " three-piece " metal plate Standard Machines Case, this cabinet are mainly made of pedestal, upper cover front cover three parts；Another kind is " five face of pedestal is plus lid " metal plate Standard Machine Case, the pedestal and upper cover that this cabinet is mainly enclosed by five bread form.And all there are some disadvantages in both cabinets：For " three Part set " metal plate standard PC case, a kind of most commonly used cabinet of the metal plate standard PC case of this form, due to its Assembly part compared with More, joint surface is more, not only wastes assembly work, it is often more important that these joint gaps are easy leakage electromagnetic wave, the electricity of cabinet Magnetic is compatible with（EMC）Performance is bad；For " five face of pedestal is plus lid " metal plate standard PC case, circuit board can not be made（PCBA）Terminal Directly expose simultaneously from the front and back of cabinet.Because if so that circuit board from size（PCBA）Terminal slave The front and back of case is directly exposed simultaneously, then can not be assembled because of interference.Therefore, the Sheet-metal machine box of this form is only fitted The case where for only needing single side directly to expose terminal.

Utility model content

Based on this, the purpose of the utility model is to overcome at least one deficiencies of the prior art, provide a kind of novel mark Quasi- cabinet；Joint gap is being reduced, the electromagnetic compatibility of cabinet is improved（EMC）While performance, needs can be installed before cabinet Face and the circuit board for directly exposing terminal simultaneously below.

In order to achieve the above objectives, the technical solution adopted in the utility model is：

A kind of novel standard cabinet is provided, cabinet is hexahedron, and the cabinet includes pedestal and upper protecgulum；Pedestal includes four A face, respectively bottom surface, back, the left side, the right side；Upper protecgulum includes two faces, respectively above, front；Behind pedestal, on Through-hole is offered before protecgulum respectively.

In said program, after cabinet is divided into pedestal and upper protecgulum, the joint gap of cabinet entirety tails off；With preferable Electromagnetic compatibility（EMC）Performance, simultaneously as gone forward on lid and bottom seat before cabinet with being located at below, i.e., before cabinet with It can relatively move below, therefore, mounting circuit boards（PCBA）When, the terminal of circuit board can be from the logical of the front and back of cabinet The case where directly exposing simultaneously in hole, be applicable in terminal from the front and back of cabinet while directly exposing, being also suitable only needs The case where wanting single side directly to expose terminal；Simultaneously as installation joint surface is less, easy for installation, when assembly, can save working hour.

Further, the upper protecgulum is integrally formed, and does not have seam between front above.Integrally formed upper protecgulum is not It is only easy to process, while the joint gap of finished product cabinet can be reduced, improve the electromagnetic compatibility of cabinet（EMC）Performance.

Further, the junction above and front is equipped with indicator light.Indicator light is before cabinet and upper Face so that no matter the case where cabinet, which is rack installation, either hangs wall installation, and user can easily see indicator light display, Since upper protecgulum is integrally formed, the fastness that heat emission hole does not interfere with junction is opened up with the junction of front above, and It is easy to process.

Further, the cabinet is provided with hangers, and cabinet can be installed on by hangers in rack.

Further, the hangers is both sides or two sides behind elongation moulding before cabinet.By both sides before cabinet or The hangers of two sides behind elongation moulding when being installed on cabinet in rack, is connected firmly, while can save the installation step of hangers Suddenly.

Further, the hangers is removably installed in both sides or two sides behind before cabinet.In the present solution, working as cabinet For rear outlet when, hangers can be mounted on cabinet before both sides；And when cabinet is preceding outlet, it, will after lower hangers can also be dismantled It is mounted on cabinet two sides behind；It is that can facilitate realization " rear outlet " according to the concrete condition of installation environment or realize " preceding outlet ".

Further, the cabinet is Sheet-metal machine box, is process by Metal plate.Metal plate（Steel plate, aluminium sheet, copper Plate etc.）It can play electromagnetic shielding, and Same Part consistency of thickness is light-weight, intensity is high, processing performance is good.

Further, the pedestal and upper protecgulum are connected by screw.Pedestal and upper protecgulum are connected and fixed by screw, It avoids pedestal and upper protecgulum junction gap excessive, causes serious electromagnetic exposure.

Compared with prior art, the utility model has the beneficial effects that：

1. circuit board（PCBA）Terminal can from the front and back of cabinet simultaneously directly expose, use is more convenient.

2. joint gap is few, electromagnetic compatibility is improved（EMC）Performance.

3. convenient for assembly, assembly work is saved.

4. hangers not only may be mounted at before cabinet（Outlet afterwards）, and may be mounted at behind cabinet（Before go out Line）.In this way, can facilitate realization " rear outlet " according to the concrete condition of installation environment or realize " preceding outlet ".

No matter 5, cabinet is that wall installation is either hung in rack installation, user can easily see the feelings that indicator light is shown Condition.
