Specific embodiment

To explain the technical content, the achieved purpose and the effect of the present invention in detail, below in conjunction with embodiment and cooperate attached Figure is explained.

Please refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the shielded box of high-low temperature chamber of the invention with monitoring temperature, including screen Cover case ontology 1, communication link 2 and tightening device 3；

The shielded box ontology 1 includes case lid 11 and cabinet 12；11 side of case lid is articulated with cabinet 12, case lid 11 Top is equipped with temperature display 111, and the temperature display 111 is electrically connected with temperature sensor 113, the temperature sensor 113 are set in 12 inner cavity of cabinet, and 11 bottom of case lid and 12 inner wall of cabinet are provided with and inhale wave layer 13, the shielded box sheet The opposite two sides of body 1 are provided with elastic component 14, and the elastic component 14 is used for the unlatching of power-assisted case lid 11；

The communication link 2 include Interface filters 21, PIN circumscription sockets 22, USB circumscription socket 23, outside SMA Connector 24, PIN inner joint 25, USB inner joint 26 and SMA female connector 27；

The Interface filters 21 are set in the one side wall of cabinet 12, and the filter is located at the side of 12 inner wall of cabinet It is provided with PIN inner joints 25, USB inner joint 26 and SMA female connector 27, the filter is located at the side of 12 outer wall of cabinet It is provided with PIN circumscription sockets 22, USB circumscription socket 23 and SMA outconnector 24, the PIN inner joint 25 connects PIN head Circumscription socket 22, the USB inner joint 26 connect USB circumscription socket 23, and the SMA female connector 27 connects SMA outconnector 24；

The tightening device 3 is used for locking case lid 11 and cabinet 12 when case lid 11 and the closure of cabinet 12.

The working principle of the shielded box with monitoring temperature is used in above-mentioned high-low temperature chamber are as follows: in use, by shielded box ontology 1 Case lid 11 open, PCB to be measured is put into cabinet 12, by the line of PCB respectively with PIN inner joints 25, USB inner joint 26, SMA female connector 27 connects, and temperature display 111 and temperature sensor 113 is opened, temperature display 111 is shown currently Temperature in shielded box ontology 1；

The hatch door of high-low temperature chamber equipment is opened, temperature parameter is set, the shielded box ontology 1 equipped with PCB to be measured is put into In high-low temperature chamber equipment, instrument and computer and shielded box ontology 1 are passed through into PIN circumscription sockets 22, USB circumscription socket 23, SMA Outconnector 24 connects, and the case lid 11 of shielded box ontology 1 is in the open state at this time, and high-low temperature chamber equipment hatch door is closed, is opened High-low temperature chamber heating mode is moved, is started to warm up inside high-low temperature chamber, when high-low temperature chamber internal temperature reaches preset testing standard When value, whether temperature of the observation shielded box ontology 1 under 11 opening state of case lid be consistent with the internal temperature of high-low temperature chamber setting, If consistent, first step test can be started；

After the completion of first step test, the hatch door of high-low temperature chamber is opened, case lid 11 is closed into merga pass tightening device 3 and is locked Case lid 11 and cabinet 12, after being closed shielded box ontology 1, operator is exited rapidly, closes high-low temperature chamber hatch door, in order to avoid temperature flow Lose serious, the internal temperature for observing current shielded box ontology 1 after closing high-low temperature chamber equipment hatch door and temperature inside high-low temperature chamber Whether degree is consistent with parameter setting temperature, if inconsistent, waits a moment, to current 1 internal temperature of shielded box ontology and height Incubator internal temperature reaches consistent with parameter setting temperature, then carries out second step test；

End to be tested opens the hatch door of high-low temperature chamber equipment, by PIN circumscription sockets 22, USB circumscription socket 23, SMA The connection of outconnector 24 disconnects, and shielded box is taken out, and opens case lid 11, and the line of PCB to be measured is disconnected, and takes out, tests Finish.

Seen from the above description, the beneficial effects of the present invention are: high-low temperature chamber provided by the invention band monitoring temperatures Shielded box can be used in the limited inner space of high-low temperature chamber compared to traditional shielded box, mainboard to be measured is existed It simulates and carries out equipment test in high and low temperature environment, to substantially increase the accuracy of mainboard test, and subsidiary temperature sense dress It sets, delicate structure is light, and isolation is high.

Further, the tightening device 3 includes clinching 31, withholds bar 32, handle 33 and hasp 34, and the hasp 34 is solid Surely it is connected to the outer wall of cabinet 12, the handle 33 and the clinching 31 are rotationally connected with 11 top of case lid, the handle 33 One end be fixedly connected with and withhold bar 32, one end of the clinching 31 is equipped with guide groove 311, it is described withhold bar 32 and be arranged in lead Into through slot 311, the other end and hasp 34 of the clinching 31 are fastened, and the handle 33 drives 31 turns of clinching by withholding bar 32 It is dynamic to realize the fastening between clinching 31 and hasp 34 with separate.

Seen from the above description, by the setting of tightening device, when case lid closes, by lower handle one end, it is located at handle The bar of withholding of the other end drives one end of clinching to move upwards, until the clinching other end and hasp fasten, case lid and cabinet at this time In closed state.

Further, the elastic component 14 is nitrogen gas spring, is set on the cabinet 12 in the one side wall hinged with case lid 11 There is first connecting portion 141, the separate roof with 12 hinged place of cabinet is equipped with second connecting portion 142 on the case lid 11, described One end of nitrogen gas spring is rotationally connected with first connecting portion 141, and the other end is rotationally connected with second connecting portion 142.
