Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Example (b):

as shown in fig. 1-3, the three-phase key-free uninterrupted meter-changing device comprises a plug-in main body 1, wherein a base 2 in which seven binding posts 14 are inserted is arranged on one side of the plug-in main body 1, two adjacent binding posts 14 are respectively connected with an incoming line and an outgoing line, the base 2 is connected with the plug-in main body 1 through screws, and the outer side of the base 2 is hinged with a flip cover 3.

Three conducting strips 21 are arranged in the base 2, each conducting strip 21 corresponds to two adjacent binding posts 14 which are respectively connected with an incoming line and an outgoing line, one side of each conducting strip 21 is in matched contact with the binding post 14, the other side of each conducting strip 21 is connected with the splicing main body 1 through a spring 22, and a push rod 23 which is in linkage fit with the flip cover 3 is further arranged on each conducting strip 21; the push rod 23 is made of a non-conductive material. The conducting strip 21 is provided with two arc-shaped grooves 211 matched with the outer surface of the binding post 14. The design of the arc-shaped slot 211 enables the conducting strip 21 to be more attached to the terminal 14, so that the work is more stable and reliable. The flip 3 is provided with a pressing block 32 which presses the push rod 23.

The plug main body 1 is provided with a mounting seat 13 for fixing the spring 22, and the spring 22 extends into the mounting seat 13 to be connected with the plug main body 1, so that the compression and recovery stability of the spring 22 is better.

When the electric meter is normally metered, the flip cover 3 is closed on the base 2, the push rod 23 is pressed by the flip cover 3, the spring 22 is in a compressed state, and the conducting strip 21 is separated from the binding post 14; when the ammeter needs to be changed, the flip cover 3 is turned outwards, the flip cover 3 does not abut against the push rod 23 any more, the conducting strip 21 is in contact with the wiring terminal 14 under the elastic action of the spring 22, short circuit between the wiring terminal 14 for incoming wire and the wiring terminal 14 for outgoing wire is realized, and a current closed loop of an electricity utilization place is formed. At the moment, the ammeter is replaced, and the electricity utilization place can still be electrified normally to work, so that the ammeter can be replaced without power outage. After the ammeter is replaced, the flip cover 3 is closed, the flip cover 3 abuts against the pressing push rod 23 again, the push rod 23 pushes the spring 22 to be compressed, the conducting strip 21 is separated from the binding post 14, and the new ammeter recovers normal metering and normal electricity utilization in an electricity utilization place.

The two sides of the plug main body 1 are provided with sliding strips 11, and the two sides of the base 2 are provided with sliding chutes 24 which are in sliding fit with the sliding strips 11. One side of the base 2 facing the plug main body 1 is provided with a first hook 25, and the plug main body 1 is provided with a first bayonet 12 which is matched and clamped with the first hook 25.
