Abstract
The invention provides a terminal button box for preventing weak current connecting pieces from rotating, which ensures that the weak current connecting pieces cannot rotate along with screws when fixed and is more convenient to install. The terminal button box comprises the weak current connecting pieces and a terminal button box body, wherein the terminal button box body is provided with a plurality of grooves; each weak current connecting piece is connected to the bottom surface of each groove through screws; and at least one lug boss which is in basic contact with the weak current connecting piece in the groove is arranged on the bottom surface of each groove.
Description
Technical field
The present invention relates to a kind of connection box of electric energy meter terminal box, especially electric energy meter anti-transition of the ramp box of forming by perpendicular type weak current connecting and terminal box body.
Background technology
Electric energy meter is the metering outfit of metering electric energy, the ramp box is the important component part of electric energy meter, light current terminal on the terminal box is as error-detecting, 485 communications, day timing output usefulness, for the ease of measurement centre of electric company calibration, on pulse output end and 485 lead-out terminals, connect copper sheet (weak current connecting) in succession.Referring to Fig. 1-3, terminal box body 4 has a plurality of grooves 1, and each right angle weak current connecting 2 is connected on the bottom surface 11 of each groove by screw 3.According to the requirement of national grid, the width of each groove is incomplete same, and what have is wide, and what have is narrow.But when producing, for the convenience of producing, the width of each weak current connecting generally equates.This has just brought a problem, and by tightening (or unclamping) screw 3 fixedly during weak current connecting 2, weak current connecting follows screw to change, and can not very easily weak current connecting be in place, and often needs manual adjustment, has influenced work efficiency greatly; Electric company installs collection at the scene needs when copying loose 485 terminal screws carry out wiring, and adjacent like this weak current connecting rotates because of meeting and two braces often occur and run into and form short circuit together, causes the difficulty of debugging.Therefore, there is certain limitation in existing terminal box at installation brace and the on-the-spot collection of installing when copying.
Summary of the invention
When the purpose of this invention is to provide a kind of fixedly weak current connecting, weak current connecting can be along with screw turns, and the terminal box that preventing weak current connecting more easily rotates is not installed.
The terminal box that preventing weak current connecting of the present invention rotates comprises weak current connecting, terminal box body; The terminal box body has a plurality of grooves, and each weak current connecting is connected the bottom surface of each groove by screw; At least have on each groove floor with this groove in a boss contacting substantially of a side of weak current connecting.
Beneficial effect of the present invention: because boss contacts substantially with a side of weak current connecting, so when tightening screw, weak current connecting can not rotate on the bottom surface of groove with screw, can very easily weak current connecting be in place, need not manual adjustment, improved work efficiency; Electric company installs collection at the scene needs when copying loose 485 terminal screws carry out wiring, and adjacent like this weak current connecting can be because of not rotating, and adjacent two braces can not occur and run into together phenomenon, and debugging is convenient.As for saying, basic contact is meant that gap between weak current connecting side and the boss relative with it is less than 0.5mm.Such gap is arranged, and is in order easily weak current connecting to be put in the groove.Theoretically, a contacts side surfaces of boss and weak current connecting also is fully feasible.
Above-mentioned terminal box, for weak current connecting is reliably located, have on each groove floor with this groove in two boss contacting substantially of weak current connecting two sides.Preferably the width of each weak current connecting equates, conformity of production is good like this, can enhance productivity, and weak current connecting is narrower with respect to existing weak current connecting width, has saved copper material, has reduced cost.

Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
The terminal box that preventing weak current connecting shown in Fig. 4-6 rotates comprises right angle weak current connecting 2, terminal box body 4, screw 3.Terminal box body 4 has a plurality of grooves 1, and each weak current connecting is connected on the bottom surface 11 of each groove by screw.On the groove floor of a groove 12, have with this groove in a boss 5 contacting substantially of a side of weak current connecting, have on the groove floor of other groove 13 with this groove in two boss 6,7 of contacting substantially of weak current connecting two sides.The width of each weak current connecting 2 equates.Be placed on weak current connecting between the boss 6,7 or between the side 121 of boss 5 and groove 12, when twisting screw, because the barrier effect of the barrier effect of boss 6,7 or boss 5, side 121, use electric tool fixedly during weak current connecting weak current connecting spinned about no longer, it is easier that weak current connecting is installed, and improved throughput rate greatly.
Width X between the boss 6,7, perhaps the width Y between boss 5, the side 121 all than the big 0.5mm of weak current connecting width W, is convenient to place brace.
After adopting such structure, because the weak current connecting unification is a size, the processing weak current connecting only needs a mould, has reduced equipment cost, has improved working (machining) efficiency; The width of brace has reduced, and copper material consumption has reduced, and cost has also reduced.
Claims (4)
1. the terminal box of preventing weak current connecting rotation comprises weak current connecting, terminal box body; The terminal box body has a plurality of grooves, and each weak current connecting is connected the bottom surface of each groove by screw; It is characterized in that: have at least on each groove floor with this groove in a boss contacting substantially of a side of weak current connecting.
