The aperture in hole 221, less than the aperture of described connection jack 211, is suitable to and institute with being connected between jack 211 formation at plug wire hole 221
State the step surface 4 that tubular junction 12 end face offsets.When assembling inserting terminal, tubular junction 12 is inserted fixing end 21
Offset in connecting jack 211 and with step surface 4 and i.e. represent that grafting puts in place, thus avoid because tubular junction 12 grafting is not in place
And cause connecting insecure problem, the most also can be further ensured that between connection jack 211 inwall and tubular junction 12 outer wall
There are enough contacts area, thus avoid causing the problem of temperature rise because effective contact area is little as far as possible, use this structure,
When assembling inserting terminal, it is possible to wedge shape cylinder 3 is loaded by the plug wire end of plug wire hole 221.
In the present embodiment, described tagblock 2 lateral part is provided with and is suitable to electrically connect with the movable contact on automatic short circuit device
Stationary contact 23, when carrying out the operation of continuous charged renewal electric energy meter by automatic short circuit device, by stationary contact 23 and automatic short circuit
The movable contact of device contacts thus by two inserting terminals electrical connections of homophase, to avoid the power failure when changing ammeter, this is quiet
Contact 23 can use silver contact.
Further, described tagblock 2 sidepiece forms and is suitable to and the short circuit hole of the electric conductor grafting on manual short-circuit device
24, when manually short-circuit device carries out continuous charged renewal electric energy meter, homophase two grafting is inserted at the two ends of described electric conductor
In the short circuit hole 24 of terminal.
Inserting plug wire hole 221 for beneficially wire in the present embodiment, therefore the outer end at described plug wire hole 221 is provided with slotting
Enter end and be provided with chamfering.
Further, as it is shown in figure 5, the circumferentially-spaced of described Plug Division 11 is provided with vertically to away from described tubulose
Connecting portion 12 one end extend conducting strip 13, the lateral surface of conducting strip 13 is conducting surface 131, the end of each conducting strip 13 have to
The guide part 14 of direction, plug connector 1 axis bending, uses this structure to ensure that the radial expansion bullet that Plug Division 11 is bigger
Property, thus time Plug Division 11 with on electric energy meter during the grafting of electric current terminal hole more smooth and easy, and can guarantee that conducting surface 131 and current terminal
Sub-aperture inwall effectively contacts, and arranging guide part 14 is to insert current terminal sub-aperture for the ease of Plug Division 11.
In practice, positioning when installing for the ease of this inserting terminal, the lateral part of described tagblock 2 forms beneficially
The detent being located, as accommodation, it is possible to arranges positioning boss on tagblock 2 and positions it, is installing this grafting
During terminal, positioning boss corresponding with in electric energy meter torr to detent on it or positioning boss or detent are coordinated.
