Description
Technical field
The present invention relates to communication test technical field, in particular to a kind of telecommunication circuit tests shielded box.
Background technique
Electromagnetic wave is one of most common carrier in the communication technology, but electromagnetic wave is ubiquitous, therefore section communication electricity
The plate extraneous electromagnetic interference that needs to forgo when test in road could be completed to test, and obtain normal experimental data.And due to
The diversity of circuit board, therefore complicated connect wires road and measurement circuit are stored in shielded box, and shielded box is all using metal
It is made, can not see internal situation, resulting in wiring very difficulty in this way, (according to windowpane, glass can not stop electricity
Magnetic wave).
Summary of the invention
The technical problem to be solved in the present invention is to provide one kind to realize visual lead on the basis of not influencing shield effectiveness
Believe circuit test shielded box.
The technical solution of the present invention is as follows:
A kind of telecommunication circuit test shielded box, including cabinet made of metal, the cabinet is interior to be used for equipped with fixing clamp
Clamping circuit board, cabinet side set Packed chamber door, are provided at least one on the either side or chamber door of the cabinet
Window, the window are inlaid with shield glass；The shield glass includes canned paragraphs and filled section, sets cavity in the canned paragraphs
Mercury is stored, hollow interlayer is set in filled section and is connected to the cavity, and the hollow interlayer total volume is less than total volume of hollow.
Further, the side of cabinet and chamber door are provided with window.
Further, shield glass uses tempered glass.
Further, in cabinet two sides, arrangement is a pair of or multipair for fixing clamp setting.
Further, the hollow interlayer thickness of filled section is not less than 0.5mm.
Further, hollow interlayer thickness in filled section is between 0.6-0.8mm.
Further, the cavity of canned paragraphs uses square cavity.
Further, chamber door is connect using hinged or inserting with cabinet
The invention has the beneficial effects that:
The special window structure of the present invention, can be convenient operator before circuit board testing see internal feelings clearly
Condition, convenient for wiring and the tested circuit board of installation etc., test, which starts to overturn cabinet, to utilize mercury that cabinet is thoroughly close
Envelope completes electromagnetic shielding.

Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
It is as shown in Figs 1-4:
A kind of telecommunication circuit test shielded box, including cabinet made of metal 1, the interior fixing clamp 5 that is equipped with of cabinet 1 are used
In clamping circuit board 6,1 side of cabinet sets Packed chamber door 2, be provided on the either side or chamber door 2 of the cabinet 1 to
A few window 3, the window 3 are inlaid with shield glass 4；The shield glass 4 includes canned paragraphs 42 and filled section 41, described
Cavity storage mercury is set in canned paragraphs 42, is set hollow interlayer in filled section 41 and is connected to the cavity, and the hollow interlayer is total
Volume is less than total volume of hollow.For omnibearing observation, in the case where not influencing internal circuit arrangement, the side of cabinet 1 and
Chamber door 2 is provided with window 3.Since mercury belongs to toxic volatile materials, for the sake of safety, shield glass 4 uses tempering glass
Glass.And the case where in view of possible muti-piece circuit synchronization test, for the setting of fixing clamp 5 in 1 two sides of cabinet, arrangement is a pair of or more
It is right.In order to ensure the effect of shielding, the hollow interlayer thickness of filled section 41 is not less than 0.5mm, preferably between 0.6-0.8mm.
While in order to reduce the thickness of canned paragraphs 42, the cavity of canned paragraphs 42 uses square cavity.Chamber door 2 of the present invention using hinged or
Inserting is connect with cabinet 1, remaining existing sealing means can also be used.It is tested as needed as internal measurement circuit
Circuit board line arrange or determine, it is different because of circuit board herein, repeat no more.
Mercury and lead are electromagnetism and the strongest substance of radiation shielding capability, but mercury is liquid at normal temperature, the present invention
It is fed into 4 canned paragraphs 42 of shield glass (priming by vacuum), when cabinet handstand (canned paragraphs 42 are located below), the equal position of mercury
In in canned paragraphs 42, the filled section 41 of shield glass 4 be it is transparent, experimenter can from window inner case, convenient for surveying
The installation and wiring for trying circuit board, are installed and are fixed circuit board using fixing clamp, shut chamber door later, then fall cabinet
It is vertical, since hollow interlayer total volume is less than total volume of hollow, so the mercury in cavity can fill hollow clamping completely, make cabinet
1 forms closed electromagnetic shielding environment.It is proposed that being not easy to since its structure is special for moving for laboratory test
Dynamic test.
In conjunction with attached drawing, the embodiments of the present invention are described in detail above, but the present invention is not limited to described implementations
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
