Description
The utility model relates to a kind of ammeter (being watt-hour meter) install bin, is specifically related to a kind of anti-electricity-theft ammeter install bin.
Ammeter install bin of the prior art mainly is made up of base, installing plate and lid, and base cooperates the tank shell that constitutes ammeter box, installing plate to be located in the case shell and is fixed on the base with lid, and ammeter is fixed on the installing plate and adopts lead to carry out respective electrical and connects.Though this ammeter install bin is simple in structure, cheap, opportunity is arranged on the structure power stealing person.Power stealing person often opens the ammeter terminal box, directly from the end of incoming cables power taking, makes ammeter lose the metering effect, has caused the power supply department economic loss.
The purpose of this utility model provides a kind of anti-electricity-theft ammeter box.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti-electricity-theft ammeter box, comprise base, lid and installing plate, base and the case shell that covers the formation ammeter box, installing plate is located in the case shell, installing plate is provided with at least one ammeter installation position, each below, ammeter installation position, be close to ammeter terminal box port and be provided with one anti-electricity-theft, anti-electricity-theft is embedded with " L " shape contact rod, its quantity and ammeter advance, the outlet number equates, one end of contact rod from anti-electricity-theft end face protrude upward and the position corresponding one by one with the terminal box port of ammeter, the other end of contact rod stretches out from the installing plate back side and is electrically connected with corresponding junction block, is alternate between the contact rod and column distribution; Base is provided with the location structure of installing plate, is provided with at least one pair of fastener structure between the installing plate back side and the base, and installing plate is being located after fastener structure is locked on the base on the base.
In the technique scheme, described anti-electricity-theft can be adopted from fastening the fixedlying connected in the installing plate back side with installing plate, also can be made into one with installing plate with anti-electricity-theft.Described fastener structure can also can be single hook fastener for the double hook fastener.The installing plate of described each top, ammeter installation position is provided with vertical chute, and chute is provided with ammeter securing member is installed, and described chute-type ammeter is installed securing member and anti-electricity-theft formation cassette ammeter mounting structure on installing plate.Have wiring hole on the described installing plate, be fixed with ammeter inlet wire junction block on the base, wiring hole is provided with the transition busbar over against the junction block setting in the wiring hole, one end of transition busbar is connected with the ammeter inlet wire contact rod at the installing plate back side, and the other end is connected with junction block through screw.The position of described wiring hole is located at the best in the installing plate zone that the ammeter back side hides.Described junction block can be the convex junction block, and the convex busbar is housed on the convex junction block, and its boss is over against wiring hole and have screw.The xsect that described contact rod protrudes upward end from anti-electricity-theft end face can be semicircle or circle lacks.
In the technique scheme, described ammeter can be that single-phase ammeter also can be a three-phase kilowatt-hour meter.Described " ammeter installation position " is meant the relative position of ammeter on installing plate.Described " installing plate is provided with at least one ammeter installation position ", its connotation is: a cover watt-hour meter device can be installed in the anti-electricity-theft ammeter box, two cover watt-hour meter devices also can be installed simultaneously, in addition more.Described " ammeter into and out of the line number " refers to three kinds of situations: 1. single-phase ammeter is two to advance two and go out; 2. the three-phase kilowatt-hour meter of three-wire system is three to advance three and go out; 3. the three-phase kilowatt-hour meter of four-wire system is four to advance four and go out.Described " anti-electricity-theft end face " is meant anti-electricity-theft up one side under installment state.Described fastener structure is meant the syndeton that two objects (next is moving part for quiet generalized case) lock mutually by fastener.Described double hook fastener is meant the equal buckle of quiet, moving part.Described single hook fastener is meant a buckle in quiet or the moving part.
Of the present utility model installing and using is: elder generation is fixed on base on the metope and connects power supply on junction block, the installing plate that will install appliance controling element more is locked on the base in location on the base and by fastener structure, at this moment by wiring hole the transition busbar is screwed on junction block, then the terminal box port of ammeter being aimed at contact rod inserts, tighten ammeter hook and terminals screw, bonnet covers and gets final product.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Since the utility model be close to ammeter terminal box port and be provided with one anti-electricity-theft, and anti-electricity-theft be fastening or be made as one with installing plate by the installing plate back side, so just thoroughly having blocked ammeter advances wire hole, and after ammeter is installed, can't pull down anti-electricity-theft again in the installing plate front, therefore have power-steeling preventing effect and practical value preferably, also further embodied the novelty and the creativeness of technical conceive.
2. owing to be connected by fastener structure between base described in the utility model and the installing plate and pin,, just can't pull down, so more guarantee anti-electricity-theft safety, further improve anti-electricity-theft reliability in case installing plate is locked on the base by fastener.
3. this anti-electricity-theft ammeter box simple installation.Base fixing on the wall after, as long as external power supply is connected on the junction block in the base, again the transition busbar in the wiring hole is screwed on junction block, just finished ammeter box power supply and installment work.Compared with prior art improved the installment work efficient of ammeter box greatly.
4. because the utility model is provided with the chute-type ammeter above each ammeter installation position securing member is installed, it has constituted cassette ammeter mounting structure with anti-electricity-theft on installing plate, and it is more easy to make ammeter that adjusting is installed.
