Abstract

The utility model discloses a misconnection preventing combined junction box for electric energy metering. The utility model comprises a box body and a box cover, wherein connecting terminals which are mutually insulated and separated are arranged in the box body; connecting sheets are arranged between corresponding connecting terminals; on the inner surface of the box cover, positions corresponding to the connecting sheets in the box body are downwards and convexly provided with blocks. The junction box of the utility model is used for reminding operating staffs to restore a normal connection mode after check or after meter changing operation to prevent misconnection; the utility model can effectively prevent the loss record or the error record of electricity dosage of users to avoid the economic loss of power supply departments.

Description

The anti-misconnection associating of electric energy metrical terminal box

Technical field the utility model relates to a kind of electric energy metrical associating terminal box, specifically can prevent from not recover behind the field-checking the anti-misconnection associating of the electric energy metrical terminal box of normal wiring state.

The structure of background technology electric energy metrical associating terminal box comprises box body and lid two parts, is provided with voltage terminal, electric current splicing ear and brace in the box body.When carrying out the electrical energy meter calibration execute-in-place, a part of brace need disconnect, and another part brace need be connected, and restores to the original state after verification is finished again.When changing table under the "on" position also is like this.Because the site operation personnel of power supply department sometimes unavoidably can be careless and inadvertent; operation is finished after regular meeting is forgotten brace is returned to the normal mode of connection, and the lid that just closes carries out lead sealing, so at once; user power utilization just can not go on record, thereby causes the power supply department economic loss.

The summary of the invention technical problem to be solved in the utility model is to propose a kind of anti-misconnection associating of the electric energy metrical terminal box that can remind operating personnel to recover the normal mode of connection in verification or after changing table handling.

For solving the problems of the technologies described above, the anti-misconnection associating of the utility model electric energy metrical terminal box comprises box body and lid, be provided with the connection terminal that mutually insulated separates in the described box body, be provided with brace between described respective terminal, on the inside surface of described lid, with described box body in the corresponding position of brace, convex with block downwards.

The utility model is owing to adopted above-mentioned technical pattern, operating personnel are when carrying out field-checking to electric energy meter, or under "on" position, carry out electric energy meter when changing, if do not recover former state after the mode of connection change to brace, when lid and box body are fixed, because the brace that the block in the lid can not resetted hinders, lid can not normally link to each other with box body.This just reminds operating personnel need check the mode of connection that box body is interior, in case misconnection.Have only brace is resetted, lid just can close.Therefore, it can prevent the error of omission or the incorrect posting of user's electricity consumption effectively, avoids the economic loss of power supply department.

Description of drawings is described in further detail the utility model below in conjunction with drawings and embodiments.

Fig. 1 is the structural representation of the anti-misconnection associating of the utility model electric energy metrical terminal box;

Fig. 2 is that the A-A of lid among Fig. 1 is to cut-open view.

Embodiment as shown in the figure, the anti-misconnection associating of electric energy metrical terminal box comprises box body 1 and lid 2, is provided with voltage terminal 3 and current terminal 4 that mutually insulated separates in the

box body

1,3,4 of each respective terminal are provided with brace 5.Lid 2 is transparent, on the inside surface of lid 2, with each brace 5 corresponding position, convex with block 6 downwards.The particular location of block 6 be brace 5 in verification or can run into it when changing table and during in its normal wiring not can with the position of its touching.Among Fig. 1,7 expression terminal screws, the lead sealing screw of 8 expression box bodys 1 and lid 2, the mounting hole of 9 expression box bodys 1.

Claims

1, the anti-misconnection associating of electric energy metrical terminal box, comprise box body and lid, be provided with the connection terminal that mutually insulated separates in the described box body, be provided with brace between described respective terminal, it is characterized in that, on the inside surface of described lid, with described box body in the corresponding position of brace, convex with block downwards.
