Embodiment
Embodiment 1
A kind of single-phase multifunctional electric energy meter connector as shown in figs. 1-7, including base table 1, are connected with upper cover on the base table 1
2 and it is connected with and renovates 3, described renovate is provided with lead sealing screw 4 and block 5 on 3,1 front portion of base table, which is plugged with, to be connect
Plug-in unit, the connector include bottom case 6, and plug-in type is provided with copper axis contact mounting blocks 7 on the bottom case 6, and copper shaft connects
7 plug-in type of contact mounting blocks is provided with copper axis contact 8, and 7 plug-in type of copper shaft contact mounting blocks is provided with limited block
9, slide bar 10 is offered on the limited block 9, slidably connects limit body 11 on the slide bar 10, on the limited block 9
Connector lid 12 is connected with, sliding slot 13 is offered on the bottom case 6, joystick key 14 is slidably connected in the sliding slot 13, it is described
L lines connector 15 and N lines connector 16 are installed in joystick key 14,4 openings 17, institute are equidistantly provided with the joystick key 14
State the left side of joystick key 14 and the left side of copper axis contact mounting blocks 7 and the torsional spring 18 of mutual cooperation is installed, copper shaft contact 8 wraps
Fixed copper axis 19 and active copper axis 20 are included, the fixed copper axis 19 and active copper axis 20 are wound with c-type spring 21, the active copper
20 external part of axis is located in opening 17.
Protrusion 22 is provided with the joystick key 14.
Entrance hole 23 matched with fixed copper axis 19 is offered on copper shaft contact mounting blocks 7.
In use, base table 1 is ammeter, copper axis contact 8 is allowed to be inserted into 1 wiring hole of base table, using one-touch operating-controlling mechanism
Action, first allow firewire (L lines) in-out end unicom and zero curve (N lines) in-out end unicom in connector before base table 1 is extracted, wink
Between after, base table 1 is powered down, and then can extract base table 1；When being inserted into ammeter, after the moment that ammeter is switched on, firewire
(L lines) in-out end and zero curve (N lines) in-out end are each cut off, and are so realized not have a power failure and are changed the purpose of table.During specific manipulation,
Joystick key 14 is used as driving link, and active copper axis 20 is driven member, and L lines connector 15 and N lines connector 16 are installed on joystick key 14
Above, combine as a whole.Joystick key 14 and torsional spring structure 18 are into damping slide block mechanism.When on the right side of the exposed protrusion of 14 right end of joystick key,
Ammeter is powered, and disengaging electric wire connecting component disconnects, and the c-type spring 21 on copper axis contact 8 is free state or slightly Pre strained state,
Its largest outside diameter, is complete interference fit with ammeter jack, limit body 11 carry out it is spacing, torsional spring 18 to joystick key 14 1 to
Right resistance, 14 position of joystick key are stabilized in the right；When joystick key 14 moves from right to left side, disengaging electric wire connection
Part is powered, and ammeter disconnects.L lines connector 15 and N lines connector 16 in joystick key 14 touch copper axis contact 8, and inlet-outlet line is connected,
Joystick key 14 continues to move to left, and active copper axis 20 will be forced to rotate, so as to produce the effect for turning round contracting to c-type spring 21, makes its outside diameter
Minimum is narrowed down to, the jack of ammeter is not contacted completely and makes ammeter no power.The whole process that joystick key 14 is moved to the left, torsional spring
18 all reverse by masterpiece, and button spring 18 has joystick key 14 power pushed away to the left, and it is constant to maintain the position of joystick key, so that
It ensure that the unicom stability of L inlet-outlet lines and N inlet-outlet lines.The protrusion 22 that ammeter is renovated in 3 pairs of joystick keys has position-limiting action, only
After the lead sealing screw 4 that ammeter is renovated on 3 is screwed off, joystick key 14 could be acted.
A kind of single-phase multifunctional electric energy meter connector of the present embodiment, effective bonding gap coordinates and interference fit, makes peace
Fill more convenient, and ammeter can be replaced in the case of not powering off, it is more convenient to use.
