Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Detailed description, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole enforcement Example.Based on the embodiment in the utility model, those of ordinary skill in the art institute on the premise of not making creative work The every other embodiment obtaining, broadly falls into the scope of the utility model protection.
In conjunction with shown in Fig. 1 to Fig. 3, sealing test box, including main part the 1st, hide in main part 1 top end opening lid the 2nd, And the securing member 3 being connected between main part 1 and lid 2.
Main part 1 includes body the 100th, from the first installation portion 101 of body outward and convexedly stretch on body 100 The test department 102 of side, the top depression of test department 102 is formed with the test cavity 103 accommodating device under test, and test department caves in There is detecting probe 7 in 103.
Its bottom edge outward of lid 2 has the second installation portion 201, on the second installation portion 201 and the first installation portion 101 Under be oppositely arranged.
It is provided with the first sealing ring 4 between the contact surface of lid 2 and body 100.
The bottom up depression of lid 2 is formed with the dented space 202 coordinating with test department, the top limit of test department 102 It is provided with the second sealing ring 5 between the inwall of edge and lid 2.
In this technical scheme, main part is protruding upward, seal box lid bottom notch, and male-female allows device to the greatest extent may be used Can be above seal box lid so that measuring distance shortens, and significantly facilitates instrument near device detection.
In this technical scheme, between lid and main part, realize that Double seal ring seals, by close in test department top edge The extruding of seal and lid inwall constitutes first and seals, and compresses composition the by the first installation portion and the second installation portion plane contact Two roads seal.Outside, including first sealing ring, two seals circle is internal also has cavity to second sealing ring, can remain one Part inert gas.Advantage is: even if second sealing ring has a small amount of water Oxygen permeation, only can allow in two seals circle cavity Inert atmosphere water oxygen content is slightly higher, but concentration is very low, then the sealing through first sealing ring, walks around two seals The water Oxygen permeation of circle is very little.
It should be noted that the first sealing ring can be fixed on the first installation portion, it is also possible to be fixed on the second installation portion On;Second sealing ring is preferably fixed to test department tip edge, but also can be arranged at the inwall of lid.
Will be readily apparent, sealing ring together also can be only set between lid and main part, it is also possible to arrange 2 roads with On.
Offering optical transmission window 203 on lid 2, this optical transmission window 203 is corresponding with test cavity 103, and optical transmission window 203 hides It is stamped transparent panel 204.
In this technical scheme, lid reserves optical transmission window, and optical transmission window inlays quartz glass.Quartz glass transmission region Scope is very wide, all can reach more than 90% from ultraviolet to infrared light transmission rate.Can conveniently allow light arrive test cavity, irradiate To the photosensitive region of device, convenient test device electrical property under light illumination.If the device inside sealing test box is luminous, can With from the injection of the light inlet window registered permanent residence, it is achieved the luminous measurement to device.
Securing member 3 is connected between the first installation portion 101 and the second installation portion 201.Securing member 3 includes the screw matching 301 and nut 302, one end of screw 301 is rotationally connected with the second installation portion 201, and nut 302 rotates in the other end of screw simultaneously Can moving axially along screw 301, the marginal trough of the first installation portion 101 be formed be available for screw enter draw-in groove 1011.
In another technical scheme, one end of screw is rotationally connected with the first installation portion, and the second installation portion cooperatively forms There is draw-in groove.
In this technical scheme, screw is rotated by axle and is fixed on the second installation portion, and hand nutting coordinates, can be very It is locked into easily on the first installation portion.Locking and fairly simple being easily suitable in glove box, both hands operate with gloves.Locking Tightness is adjustable, and reliable lock consolidates.
Test cavity 103 periphery is vertically arranged with multiple spacing probe 6, and the plurality of spacing probe 6 is distributed in device under test Surrounding, spacing probe 6 vertical direction is resiliently displaceable, and to convexedly stretch in test chamber external on the top of spacing probe 6, spacing probe Top shape have device under test feather edge to be supported and spacing inclined plane 601.
Preferably, spacing probe 6 fits in the inwall of test cavity.
In this technical scheme, probe is not when lid presses to main part, and end of probe stretches out table on test cavity Face 1mm length, tests the preferably rectangular cavity of cavity, 2 spacing probes of its each edge, altogether stretches out 8 probes, and device is put Put in the square frame that 8 spacing probes surround, even if in operation, handshaking, do not interfere with the position that device is placed yet Put.When lid presses to main part, with quartz glass plate and test department top edge Distance Shortened, spacing probe is made at pressure Using lower retraction, probe is elastic retracts, and final probe reaches approximately the same plane with test department top surface, and the protrusion of 1mm disappears Removing, now device has been successfully entered in test cavity, and spacing probe achieves limit function.
On the one hand it should be noted that described inclined plane can be a plane or an arc, it is in order to to be measured Device carries out guiding slip and realizes to it spacing;On the other hand upon completion of the assays, by supporting role by device under test from Test cavity ejects, it is simple to taking of device under test is put.
It is provided with detecting probe 7 in test chamber body.
In this technical scheme, measurement probe is in free state when lid does not press to main part, measures probe Probe and test department upper surface in a plane.Device under test is placed above at measurement probe, allows the electricity of device under test Pole contacts with measurement probe, now owing to thickness (taking 1mm here) its upper surface of device under test is higher than test department upper surface 1mm, when lid presses to main part, with quartz glass plate and test department top edge Distance Shortened, quartz glass plate or lid Internal wall promotes the upper surface of device under test, finally allows its upper surface and test department upper surface in same level, and measurement is visited Pin decrement is 1mm, makes measurement probe reliable and stable with the electrical contact of device electrode.
Upwards caving in and be formed with a wire connection cavity 104 in the bottom of main part 1, the opening of wire connection cavity 104 is sealed with lower cover 8, connects It is provided with printed circuit board (PCB) 9 in line cavity 104.It is provided with sealing ring 10 between the contact surface of lower cover 8 and main part 1.
In this technical scheme, printed circuit board (PCB) is responsible for the electrical connection of detecting probe 7 and aviation plug 11, printed circuit Plate also is responsible for being welded and fixed spacing probe 6.In order to air-tightness is more preferable, generally after probe is fixing and circuit connection is intact, make Fill up whole sealing test box main body wiring cavity with sealing casting glue, the air-tightness of sealing test box can be greatly increased.
Being embedded with aviation plug 11 in main body 1, this aviation plug 11 is connected to printed circuit board (PCB) 9.
In this technical scheme, aviation plug is embedded in above main part, can allow the connection of testing cassete and external circuit Simply, compact, reliably, sturdy and durable.
