Abstract
The utility model provides a kind of signal supervisory instrument of circuit board: comprise a hollow track, the mount pad that can slide along hollow track is housed on hollow track, the two bottom sides of mount pad is fixed with respectively sniffer and display device, and the circuit series connection of described sniffer and display device communicates.Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, work people far can be by mechanical operation, the qualification of the testing product of larger efficiency, reduce personnel's use amount, and machinery can be worked for a long time, adjustable sniffer also can detect multiple trouble spots, increases work efficiency.
Description
Technical field
The invention belongs to circuit board detecting field, especially relates to a kind of signal supervisory instrument of circuit board.
Background technology
Circuit board detecting field in existing technology, board circuit is often due to the short circuit of circuit and corresponding line fault and cisco unity malfunction, but frequent testing staff need to detect several fixing circuit point to such an extent as to work efficiency is low, and can not carry out for a long time work also becomes the biggest obstacle of testing staff's inspection product qualification.
Summary of the invention
The invention is for addressing the above problem the signal supervisory instrument that a kind of circuit board is provided: comprise a hollow track, the mount pad that can slide along hollow track is housed on described hollow track, the two bottom sides of described mount pad is fixed with respectively sniffer and display device, and described sniffer and display device series connection communicate.
Further; Described sniffer internal side wall is provided with the holder that can move up and down, on described holder, be fixed with the detector bar that can stretch out sniffer, the top of described detector bar is provided with detecting head, and described sniffer interior bottom portion is provided with sensing chip, on described sniffer, has power switch.
Further; Described display device is provided with display lamp.
Further; Described each sniffer all has a display device in contrast should.
Further; Described sniffer can be free to slide on mount pad.Can detect each signaling point of circuit board.
Advantage and good effect that the invention has are: owing to adopting technique scheme, work people far can be by mechanical operation, the qualification of the testing product of larger efficiency, reduce personnel's use amount, and machinery can be worked for a long time, adjustable sniffer also can detect multiple trouble spots, increases work efficiency.

Embodiment
As shown in Figure 1, the signal supervisory instrument of a kind of circuit board of the invention: comprise a hollow track 1, the mount pad 2 that can slide along hollow track is housed on described hollow track, the two bottom sides of described mount pad 2 is fixed with respectively sniffer 3 and display device 4, and the circuit series connection of described sniffer 3 and display device 4 communicates.Sniffer 3 internal side wall are provided with the holder 7 that can move up and down, and are fixed with the detector bar 6 that can stretch out sniffer 3 on described holder, and the top of described detector bar 6 is provided with detecting head 5, and described sniffer 3 interior bottom portion are provided with sensing chip 8.Display device 4 is provided with display lamp 9.Display lamp can be made a response to signal, so that staff observes.Each sniffer 3 all has a display device 4 in contrast should.Sniffer 3 can be free to slide on mount pad 2.Can detect each signaling point of circuit board.The course of work of this example: adjust the position of sniffer 3 in mount pad, the circuit board that then will overhaul is fixed on hollow track 1, circuit board is by the detecting head 5 on extruding sniffer 3, and then promotion detector bar moves down contact induction sheet 8, turn on the power switch 10, now sniffer 3 will form closed series circuit with display device 4 and circuit board, sensing chip passes to current signal in display device 4, display lamp 9 is reacted and will be lighted current signal, testing staff can according to circumstances judge, the position that simultaneously mount pad 2 can slidable adjustment need detect on hollow track 1.
Above the invention embodiment is had been described in detail, but described content is only for the preferred embodiment of the invention, can not be considered to the practical range for limiting the invention.All equalization variation and improvement etc. of doing according to the invention application range, within all should still belonging to the patent covering scope of the invention.
