Voice prompting.
The jack assemblies 33 of the utility model include combination hub 25, connector 26, pressing plate 27 and lead sealing lid 28, the combination hub
Be equipped on 25 with the connector 26 of ammeter box grafting (connector 26 of the present embodiment be four), offer on combination hub 25 slotting
Hole 32, the quantity of jack 32 is identical as the quantity for patching column 3 and corresponds；Patch the insertion when not powering off displacement ammeter of column 3
In the jack 32, and abutted with connector 26.One end of lead sealing lid 28 is articulated on combination hub 25, and the other end is free end,
Off working state covers in jack 32, and is sealed by lead sealing 29.It is offered on combination hub 25 with rotation latch hook in hook-shaped one
Hold corresponding hook groove 31, the present embodiment symmetrically opens up on the combination hub 25 of 28 left and right sides of lead sealing lid there are two hook groove 31, when
After continued power ammeter displacement apparatus 34 and combination hub 25, rotation latch hook is gone in hook groove 31 in hook-shaped one end, hooks hook groove
31.Lead sealing lid 28 is located at before combination hub 25, and combination hub circuit board 30, combination hub circuit board are equipped with behind combination hub 25
There is switch and LED light, which connect for normally-closed contact relay, respectively with power supply and LED light on 30；When installation ammeter 35
Afterwards, ammeter 35 touches the feeler lever 36 on combination hub 25, disconnects switch, and LED light is extinguished.
The working principle of the utility model are as follows:
As shown in Fig. 6~15, in off working state, by the physical location of ammeter box, the connector 26 on combination hub 25
With ammeter box grafting, and ammeter 35 is loaded onto, connected the line；At this moment, ammeter 35 touches feeler lever 36, on combination hub circuit board 30
LED light is extinguished, and indicates that the utility model is connected with circuit.Lead sealing lid 28 is closed, and is sealed by lead sealing 29.Continued power ammeter is set
The column 3 that patches of changing device 34 is retracted in shell.
When work, remove lead sealing 29, lead sealing lid 28 rotated down, make combination hub 25 be in can working condition, at this moment
Continued power ammeter displacement apparatus 34 can be used.Two promotion keys 6 are pushed into shell respectively, by respectively another
Hold the jacking block 9 of connection, conduction element 2 that will patch column 3 and be pushed outwardly；During promotion, the edge of conduction element 2 and left and right lock
The location contacts that spring 8,10 is bent, the position of bending is pushed out；When position of the conduction element 2 more than bending, left and right snap 8,
10 rely on the elastic reset of itself, and the position of bending is supported on the edge of 2 lower surface of conduction element, makes to patch column 3 and interior insulation
Sheath 18 is locked, cannot withdraw, and continued power ammeter displacement apparatus 34 enters working condition, and inside and outside insulating sheath 18,17 can be prevented
Only the hand misconnection of operator, which contacts, patches column 3.The insertion of column 3 is patched by four of continued power ammeter displacement apparatus 34 again to patch
In four jacks 32 of seat 25, after continued power ammeter displacement apparatus 34 is connected with circuit, loudspeaker 23 issues voice prompting
" circuit has turned on, and can carry out tearing table work open ".
After the completion of above-mentioned work, hook key 12 is pushed away, its band moveable lock hook pull-push piece 13 is made to overcome latch hook reset spring 15
Elastic force effect push out, and then the rotation latch hook 11 of the left and right sides is driven to rotate respectively, makes to rotate latch hook 11 in hook-shaped
One end and hook groove 31 are mutually locked, can carry out the work of disassembly ammeter 35.At this point, the other end of pull-push piece snap 19 is by latch hook
It is released in the aperture of 13 other end of pull-push piece, is connected to the end of 13 other end of latch hook pull-push piece.
After tearing table open, continued power ammeter displacement apparatus 34 plays conducting in circuit, is attempted by circuit, until ammeter
35 have overhauled, and reinstall to that circuit is each, and continued power ammeter displacement apparatus 34 can just remove.
After ammeter, which has overhauled, reinstalls ammeter box, when needing to remove continued power ammeter displacement apparatus 34, press
Latch hook release tab 21 presses the other end of pull-push piece snap 19, elastic force of the latch hook pull-push piece 13 in latch hook reset spring 15
Effect is lower to be resetted, and the other end of pull-push piece snap 19 is inserted into again again in the aperture of 13 other end of latch hook pull-push piece, and latch hook unlock is pressed
Key 21 also resets under the action of latch hook unlocks spring 22.At this moment, continued power ammeter displacement apparatus 34 is in combination hub 25
Disassembly status can pull up continued power ammeter displacement apparatus 34.The continued power ammeter displacement apparatus 34 that will be removed, with double
Hand pulls out release tab 7 respectively, and the position for bending left and right snap 8,10 is abutted with the disengaging of conduction element 2, and conduction element 2 exists
It is resetted under the action of reset spring 5, continued power ammeter displacement apparatus 34 is made to restore off working state.Then lead sealing lid 28 to
Lead sealing 29 is loaded onto upper rotation, and power supply system enters normal operating conditions.
