Description
Technical field
The utility model belongs to the electric energy meter structure design field, is specifically related to a kind of electrical energy meter lead sealing structure.
Background technology
In order to prevent that electric energy meter from arbitrarily being opened, usually all can in addition lead sealing on electric energy meter.
Disclose a kind of novel plastic lead seal among the patent documentation CN202205398U, this plastic lead seal is provided with the cooperation boss, and described cooperation boss is located at the below of plastic lead seal upper surface, and cooperates the outside dimension of boss greater than the outside dimension of plastic lead seal.After electric energy meter base and table cover are connected by the lead sealing screw plastic lead seal is located at the top of lead sealing screw and it is installed in the lead seal hole of table cover by the interference fit mounting means.Simultaneously be equipped with the hole by also finding out accurately in table cover and lead sealing screw in the accompanying drawing 3 in this patent documentation, pass the hole realization of the hole of table cover and lead sealing screw to the secondary lead sealing of electric energy meter with the lead sealing line after power office's calibration is finished.
A kind of electrical energy meter lead sealing structure is disclosed among the patent documentation CN201035051Y, it comprises lead sealing screw and instrument lid, above the lead sealing screw, be provided with lead sealing lid (being equivalent to the plastic lead seal among the patent documentation CN202205398U), described lead sealing covers and is provided with Elastic buckle, and correspondingly instrument covers and is provided with just in time the boss that fastens with buckle.Simultaneously be equipped with the hole by also finding out accurately in the accompanying drawing 2 in this patent documentation at instrument lid and lead sealing screw, employing lead sealing line passed the hole realization of the hole of instrument lid and lead sealing screw to the secondary lead sealing of electric energy meter after power office's calibration was finished.
Technical scheme in above-mentioned two patent documentations is substantially identical, they when carrying out the secondary lead sealing, if in the situation that the lead sealing screw urgent, the hole of lead sealing screw is higher than the position in the hole that is arranged on table cover, then can't wear the lead sealing line; If in the situation that the lead sealing screw is urgent, the hole that is arranged on the lead sealing screw is lower than the position that is arranged on the hole on the table cover, then when carrying out the secondary lead sealing, need to return the part screw thread of lead sealing screw, the hole that makes the lead sealing screw aims at the hole on the table cover so that wear the lead sealing line, both reduced the sealing that work efficiency has also affected watchcase simultaneously and return the part screw thread; Thereby as to adopt in above-mentioned two patent documentations lead seal structure to security sealing for electric energy meter, for easily passing the sealing that does not affect watchcase for the lead sealing line, just must guarantee hole on the lead sealing screw and the alignment setting of the hole on the table cover when the lead sealing screw is urgent, yet this point is difficult to but in practical operation reach fully.
The utility model content
For the defective that exists in two patent documentations in the background technology, the utility model aims to provide and a kind ofly easily carries out the secondary lead sealing, and the electrical energy meter lead sealing structure that can not impact tightness of case.
The technical scheme that realizes the utility model purpose is:
A kind of electrical energy meter lead sealing structure, the base and the table cover that consist of meter shell of electric energy meter are connected by screw; Described screw is located in the lead seal hole of described table cover, is provided with the lead sealing lid in the described lead seal hole above described screw; Described lead sealing covers the through wires hole that is provided with perforation, and the sidewall of described lead seal hole is provided with cable-through hole, and the lead sealing line passes described cable-through hole and is connected through wires hole the lead sealing lid is connected with table cover.
In the technique scheme, described lead sealing lid also with described table cover clamping.
In the technique scheme, the lateral wall of described lead sealing lid is provided with Ka Tai/draw-in groove, and lead seal hole and the Ka Tai/draw-in groove of described table cover are provided with draw-in groove/Ka Tai over against the position; Described card decometer is located in the corresponding draw-in groove.
In the technique scheme, the outside dimension of described lead sealing lid is not less than the internal diameter size of the lead seal hole of described table cover.
The utlity model has positive effect:
(1) lead seal structure in the utility model is tightened first screw when operation, then the lead sealing capping plug is entered in the lead seal hole as a lead sealing, again lead sealing lid and table cover are connected to realize secondary lead sealing to electric energy meter by the lead sealing line, owing to being like that with lead sealing line connection lead seal screw and table cover in the utility model with lead sealing line connection lead seal lid and table cover and among non-patent literature CN202205398U and the patent documentation CN201035051Y, hole therefore need not align on the lead sealing screw and the hole on the table cover, just there is not the situation that to return lead sealing bolt portion screw thread yet, therefore can the sealing of watchcase do not impacted.
(2) lead sealing in the utility model lid also with described table cover clamping; Adopt clamping can further guarantee the reliability that the lead sealing lid is installed.
