Abstract

The utility model relates to a socket with an inserting type of an electric energy meter, which is characterized in that a socket plate is respectively provided with at least three main socket: a phase wire input main socket, a zero wire input and out main socket and a phase wire output main socket; each of the main sockets are respectively electrically connected with at least three binding posts arranged on a base under the socket plate. The utility model causes the operation of timekeeping of a changing meter on the spot to be carried out by one person and the type of dismounting and connecting wires on the spot to be changed into a simple inserting and pulling type to operate, which greatly enhances the work efficiency.

Description

Plug-in type electric energy table socket

The utility model relates to a kind of socket of ammeter.

In the prior art, AC energy meter all has the link box without exception, need carry out wiring at the scene and just can put into operation and measure.The type has following shortcoming: since such electric energy meter at the scene wiring just can come into operation, and environmental baseline poor, various interference in working-yard is many, so labour intensity is big, easily wrong line and cause the metering misalignment.Regulation according to " measurement Law ", the charge electric energy table belongs to the compulsory verification measuring apparatus, single-phase AC electric energy table was examined and determine once in per 5 years by turns, because " hot line job " in the lead rotation schedule genus " electric power safety rules " torn, connect at the scene open, must two people carry out wherein people monitoring simultaneously, one man operation is to guarantee personal safety, therefore this operation is time-consuming, and efficient is low, and bigger danger is arranged again.All table wiring in casees all are exposed to the outside, stealing easily, steal table.Owing to need wiring at the scene, must leave enough big operating space between the electric energy meter in the table case of place, cause supporting gauging table casing long-pending excessive, difficulty is installed in the bottom of residential building passageway.

The purpose of this utility model is to provide a kind of plug-in type electric energy table socket that can carry out socket connection with electric energy meter.

The technical solution of the utility model is: a kind of plug-in type electric energy table socket, be respectively equipped with at least three baseplugs on the socket, be respectively phase line input, zero line input and output, phase line output baseplug, described each baseplug respectively with the base of socket below at least three binding posts being provided be electrically connected separately.

The utility model compared with prior art has following advantage:

Because socket adopts the isolation full-closed structure of insulation, thereby has guaranteed that human body can not touch wherein any current-carrying part, makes on-the-spot rotation schedule timing, only need personnel, and the scene is disconnected line change simple plug-in operation into, work efficiency greatly improves.All wiring all can be arranged behind plate in the table case, and the electricity filching behavior by the reconfiguration line can't be carried out.Factory installs all case internal wirings when producing electric energy meter metering bamboo mat, and the strictness of batch production is checked, and has guaranteed the correctness of wiring.Because plug-in type electric energy table does not need the scene to disconnect line, the original operating space of electric energy meter can be saved, and the electric energy meter casing is long-pending to be dwindled greatly thereby make, and originally the situation of electric energy meter case installation difficulty was changed greatly on the bottom of residential building passage.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is the structural representation of the utility model when being connected with the plug-type ammeter;

Accompanying drawing 2 is the vertical view of the plug-type ammeter of accompanying drawing 1 after pulling out; Wherein:

[1]. auxilliary socket; [2]. auxilliary plug; [3]. socket; [4]. ammeter; [5]. lock body; [6]. locking bar; [7]. dead bolt; [8]. lockhole; [9]. main plug; [10]. jump ring; [11]. baseplug; [12]. binding post; [13]. base;

Embodiment: referring to accompanying drawing 1 and accompanying drawing 2, a kind of plug-in type electric energy table socket, socket [3] is provided with and is respectively equipped with phase line input, zero line input, zero line output, phase line output four baseplugs [11], described each baseplug [11] is electrically connected with corresponding four binding posts [12] on the base [13] of socket [3] below respectively, and described binding post [12] is used to connect power lead.Also be provided with on the described socket [3] as check meter two auxilliary sockets [1] of interface of computing machine, described each auxilliary socket [1] is electrically connected with corresponding two other binding post [12] on the base [13] of socket [3] below respectively, and this binding post [12] can be connected with the computing machine meter copying device when needed.The outside of two contact chips of described baseplug [11] is clamped by jump ring [10], described jump ring [10] is selected annular spring for use, block two outsides of two contact chips by the peristome of annular spring [10], in order to strengthen the elasticity of baseplug [11], make the main plug [9] of contact chip and insertion keep excellent contact, avoid owing to the loose contact of ammeter master plug [9] with baseplug [11] causes generating heat.The both sides of described socket [3] are connected with lock body [5], being provided with in the described lock body [5] can be with respect to the locking bar [6] of lock body [5] rotation, the xsect of described locking bar [6] is a triangle, vertically be provided with the dead bolt [7] in the lockhole [8] that is used to insert electric energy meter on the described locking bar [6], after electric energy meter master plug [9] and auxilliary plug [2] insert corresponding socket respectively, with the endoporus of special use is that the instrument of triangular-section is inserted in the interior rotating rod lock of locking bar [6] [6], make in the lockhole [8] on dead bolt [7] the insertion electric energy meter on the locking bar [6], locking receptacles plate [3] and ammeter [4] have prevented that the behavior of stealing table and power stealing from taking place.The outside of described each baseplug [11] is provided with the electric arc division board, guarantees the contact interpolar fault that is not short-circuited.
