Description
Technical field
A kind of electric energy meter table stern construction of the utility model, belongs to electric energy meter technical field.
Background technology
When connection passes in and out wire, electric energy meter tail and conductive contact and tight is usually taken in common electric energy meter on the market at present
Gu screw connects both, but is that point contacts with screw above wire, with being linear contact lay in wire guide below wire, damage
Electric energy meter be due to largely electric energy meter tail and wire loose contact heating scaling loss, caused to electric power enterprise economy very big
Loss.
According to investigations, cause electric energy meter generate heat scaling loss the reason for be：To wiring at connection box of electric energy meter terminal, table in batch meter
The disengaging linear diameter that case producer provides is thin, while mounting process of some workmens during electric energy meter is installed also is not advised
Model；In order to accelerate efficiency in construction, on request, two turnbuckle screws are required for tightening in electric energy meter, and worker but only tightens sometimes
One screw, it is easy to make binding post and poor wire connection, contact resistance rise, heating exception, the wiring of electric energy meter occur
It if terminal was chronically at heat anomaly, can decline the mechanical strength of terminal junction, and the outer of wire is made by heat transfer
Portion's insulating materials accelerated ageing, or even disaster hidden-trouble be present, ultimately result in electric energy meter and burn.
According to statistics, the electric energy meter for scaling loss of generating heat accounting in the abnormal electric energy meter of cancelling stocks is 72%, if electric power enterprise will be protected
The normal electricity consumption of client is demonstrate,proved, must just carry out upgrading to the table tail of electric energy meter, electric energy meter is the data acquisition of intelligent grid
Can end, intelligent electric meter be related to the economic benefit of intelligent grid by Effec-tive Function for a long time, should avoid to user and enterprise's band
Carry out economic loss.
Utility model content
The utility model overcomes the shortcomings of the prior art, and technical problem to be solved is：There is provided a kind of wire with
Electric energy meter connection terminal contact area is big and the electric energy meter stern construction of stable connection.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of electric energy meter table caudal knot
Structure, including：Electric energy meter tail binding post and lead wire terminal, the end extraction wire wiring end connector of the lead wire terminal,
Welded after terminating wire end connector grafting is entered into electric energy meter tail binding post, the two is fixed as one.
The terminating wire end connector is cylindrical structure.
The terminating wire end connector is hexagon column structure.
The conductor length that the lead wire terminal reverse extending goes out is 30-50 centimetres.
The electric energy meter tail binding post quantity is four, and two of which is power end, and the inlet wire connected in ammeter box is total
It is spaced apart, two other is load end, connects in ammeter box and divides family earth leakage protective device.
The utility model has the advantages that compared with prior art：The utility model is by setting lead wire terminal
Joint, it is welded as a whole after being inserted into the table tail binding post of electric energy meter, makes the two stable connection, without passes through stubborn spiral shell in table tail
The mode of silk makes the two fastening, simplifies mounting process, and the original point contact of the two is changed into linear contact lay and face contact, reduces
Contact resistance, make electric energy meter using safer, and improve the service efficiency and durability degree of equipment；A little it is in addition, this
Utility model can not destroy the terminal structure of existing electric energy meter, and in general internal diameter chi can be used in the binding post of electric energy meter tail
Very little, lead wire terminal joint dimension is adapted the steadiness that can ensure the two connection, and the utility model extends to all presence
At the binding post of loose contact electrical equipment, versatility is stronger.

Embodiment
, below will be to the utility model to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Technical scheme in embodiment is clearly and completely described, it is clear that described embodiment is a part of the present utility model
Embodiment, rather than whole embodiments；Based on the embodiment in the utility model, those of ordinary skill in the art are not making
Go out under the premise of creative work the every other embodiment obtained, belong to the scope of the utility model protection.
As shown in Figure 1：A kind of electric energy meter table stern construction of the utility model, including：Electric energy meter tail binding post 1 and lead
Line terminals 2, the end extraction wire wiring end connector 3 of the lead wire terminal 2, enter electricity by the grafting of terminating wire end connector 3
It can be welded after table table tail binding post 1, the two is fixed as one.Lead wire terminal 2 can be poured into by general electro-insulating rubber
Type, its processing technology is simple, and the terminating wire end connector 3 of extraction can increase the contact area of binding post and wire, and reduction connects
Get an electric shock and hinder, and possess good anticorrosive metal ability, the fever phenomenon caused by loose contact can be avoided.
As shown in Figure 2：The terminating wire end connector 3 is cylindrical structure.The first embodiment of the present utility model is
General connected structure, can be applied to general electric energy meter tail, electric energy meter tail binding post 1 with after the grafting of terminating wire end connector 3
It can ensure that loop is connected, to ensure stable connection, using welding manner by the two knot that is fixed as one after the two close connection
Structure, the method that the later stage can also be used casting to connect or crimp are connected, and electric energy meter is pacified with wire as overall in ammeter box
