Abstract

A mobile gauge-check connecting terminal base relating to electrician apparatus, is essentially a connecting terminal socket for checking gauge, corresponding to the connecting terminal between a quasi-plug-in electric energy meter and a low-voltage current transformer. The socket is characterized in that all the plug holes are arranged in order in the rectangular plywood shell, while each plug hole is equipped with an elastic conductor sheet connected with a corresponding wire of a verification stand by a crimp and a connect screw. The connecting terminal base used as electric energy meter is equipped with 7-15 plug holes, and the connecting terminal base used as low-voltage current transformer is equipped with 2 plug holes. The character of the utility model is simple in use that plug-in and then extracting during checking takes place of the connecting wires before checking and disconnecting wires after checking, thereby decreasing the intensity and increasing the checking efficiency without accident.

Description

Plug formula instrument check terminal block

Technical field

The utility model relates to electrotechnical apparatus, mainly is a kind of instrument check binding post socket.

Background technology

Power supply department will constantly carry out the verification of electric energy meter and low-voltage current mutual inductor in carrying out the electric-power metering management process, be subjected to the restriction of equipment, table of every verification, the operations that must carry out wiring and take out stitches all, because of the table meter of verification every day is a lot, one of the repeatability of this dullness connects and one tears open, not only take the time but also influenced the efficient of work, add and constantly carry out wiring dry as dust and take out stitches have the situation of misoperation to occur unavoidably, cause the accident, or misunderstand reading, influence the accuracy of table.

The utility model content

The utility model promptly is to have proposed improvement at this problem, after binding post on the supporting electric energy meter summation current transformer has changed the moving contact plug-in type into by traditional compression joint type, binding post with the connection box of electric energy meter terminal summation current transformer of checking table, change corresponding with it plug formula checkout terminal stroma into, its purpose is: insert one by one and pull out and replace one to connect one and tear open, can reduce labor intensity, improve verification efficient, avoid accident to take place.Specific structural features of the present utility model is: the corresponding electric energy meter summation current transformer splicing ear of intending insertion, in each jack of the utility model bakelite body shell terminal block, be fixed with elastic conducting strip, this elastic conducting strip connects with the corresponding wiring of checking table by the crimping screw, and all jacks are arranged on it in order.

Description of drawings

Accompanying drawing 1 is the vertical profile structural representation of electrical energy meter calibration terminal block of the present utility model;

Accompanying drawing 2 is its cross-sectional structural representation;

Accompanying drawing 3 is the vertical profile structural representation of current transformer verification binding post of the present utility model;

Accompanying drawing 4 is its cross-sectional structural representation.

Among the figure, 1 is the housing of terminal block, and 2 is elastic conducting strip, and 3 are wiring crimping screw, and 4 for installing screw.

Embodiment

Basic principle of the present utility model is similar to common commercial power socket, with corresponding by the instrument terminal of verification, can remove loaded down with trivial details artificial wiring from, directly the moving plug of wiring is inserted during verification to get final product, and verification is intact extracts immediately.For the terminal block as electrical energy meter calibration, its jack is 7～15, shown in accompanying drawing 1 and accompanying drawing 2; For the terminal block as the current transformer verification, its jack is 2, and shown in accompanying drawing 3 and accompanying drawing 4, they are fixed on the checking table by screw 4.Grafting conducting strip 2 in the hole is elastic copper sheet, is locked in the bakelite shell body terminal base 1, and is fixing by crimping screw 3 when wiring in the checking table is connected.Key property of the present utility model is to use conveniently, insert and one pull out taking out stitches of another contact of contact after the wiring that replaces an original contact of a contact of elder generation and the verification with one, alleviate labour intensity greatly, verification efficient is improved, can avoid contingency to take place.

Claims

1, a kind of plug formula instrument check terminal block, the corresponding splicing ear of intending insertion, it is characterized in that: all jacks are ordered in the rectangular bakelite body shell, in each jack elastic conducting strip is housed, this elastic conducting strip connects with the corresponding wiring of checking table by the crimping screw.

2, plug formula instrument check terminal block according to claim 1 is characterized in that: as the terminal block of electrical energy meter calibration, its jack is 7～15.

3, plug formula instrument check terminal block according to claim 1 is characterized in that: as the terminal block of current transformer verification, its jack is 2.
