Abstract

The utility model belongs to the technical field of power supplies for electricity meters, and relates to an electric supply device for an electricity meter. A battery case capable of flatly containing a lithium battery is arranged on the upper lateral side of a power supply box in a hollow rectangular box structure. A conductive connecting pole plate is arranged on a concave structure on the upper side of one end of the power supply box, the inner end of the connecting pole plate is communicated with a battery electrode, and the outer end of the connecting pole plate is provided with a platy L-shaped hooked pin in an electrically communicated manner. Four inserting pins identical in structure are arranged at four end corners of the bottom face of the power supply box respectively and inserted into corresponding jacks of the electricity meter. Two welding pins identical in structure are arranged at the end, away from the connecting pole plate, of the bottom face of the power supply box. The power supply box is flatly placed in an electricity meter shell, and each pin is firmly inserted into the corresponding jack. The electric supply device for the electricity meter is simple in integral structure, convenient in use, flexible in circuit incoming, high in safety, reliability and stability, low in electricity consumption and long in service life, and can substitute an existing power supply device for the electricity meter.

Description

A kind of ammeter is used supply unit

Technical field:

The utility model belongs to the power technique fields that the voltameter scale is used, and relates to improving equipment on battery case that a kind of ammeter uses and battery profile and the size, and particularly a kind of ammeter is used supply unit.

Background technology:

At present,, in the ammeter that user's voltameter scale of electric power is used reserve battery must be installed according to national grid technology and policy document regulation, in order under the situation of cutting off the power supply in powers failure, tripping operation etc. as the standby power supply of ammeter.Existing ammeter standby power supply has various version, mainly is divided into two big types, and one type belongs to dry battery power, another kind of power supply or the charge type power supply that belongs to lithium battery or voltage stabilizing rectification; The ammeter power supply of dry cell class needs the battery case in discharge pond and the mainboard that docks with meter circuit; The conventional battery groove is connected with metering ammeter battery with 2 insertion pins through 2 bumps with mainboard; The safe reliability of this syndeton is relatively poor; Resistivity is higher, and circuit stable bad especially causes 2 to insert pins and come off in transportation easily; So battery is the lithium battery or the dry cell of 2 separations, installation and removal are not convenient.End is got up, and existing ammeter is used direct supply, its complex structure, and safe reliability is poor, and serviceable life is short, and power consumption is big, and range of application is little, and financial cost is high.

Summary of the invention:

The goal of the invention of the utility model is to overcome the shortcoming that prior art exists; Solve the convenience that battery case and fastness, stability and battery that mainboard, battery are connected with battery case in the ammeter power supply are installed, the stability and the safe reliability of the contour structures through the improvement battery case and the use mounting means realization ammeter direct supply of battery.

To achieve these goals; The utility model selects to use the lithium battery of two one through the improvement to the battery case contour structures, insertion pin, scolding tin pin and the hook pin of design battery case; Battery case is connected with mainboard with a hook pin through four insertion pins, two scolding tin pins; Many two are inserted pins and a hook pin on original battery case basis, and it is more solid and reliable that battery case is connected with mainboard, and use the lithium battery of two one; Be convenient to installation and removal, battery is more stable with contacting of battery case.

The agent structure of the utility model comprises battery, inserts pin, welding pin, hook pin, battery case, power supply box body and is connected plate; The power supply box body upper side of hollow type rectangular box structure digs and is shaped on the battery case that can smoothly put into lithium battery; The recessed formula structure of one end upside of power supply box body is shaped on the connection plate of conduction; The medial extremity that connects plate is communicated with the electrode of battery, and the outboard end general formula that is electrically connected is shaped on the hook pin of tabular L type; The place, four end angles of the bottom side of power supply box body is shaped on isostructural four respectively and inserts pin, is used for being inserted in the corresponding jack of ammeter; Be shaped on the welding pin that is used for source of welding current lead-in wire of two same structures on the bottom side of power supply box body away from the vertical structure in end that connects plate; Smooth being positioned in the ammeter housing and with the corresponding socket on each pin alignment ammeter of power supply box body firmly inserted.

The utility model compared with prior art; Through contour structures that improves battery case and the lithium battery that uses two one; In the long-term use of ammeter, battery case and mainboard, battery and battery case be connected firm, stable more, can not use or exterior vibration comes off because of not long-term; Under special circumstances, for ammeter reliable and stable power supply is provided; Its one-piece construction is simple, and is easy to install, and place in circuit is flexible, and safe reliability is good, and circuit stability is high, and power consumption is few, long service life, the supply unit that uses in the alternative existing ammeter.

Description of drawings:

The agent structure principle schematic of Fig. 1 the utility model.

Embodiment:

Below through embodiment and combine accompanying drawing to be described further.

Embodiment:

The agent structure of the utility model comprises battery 1, inserts pin 2, welding pin 3, hook pin 4, battery case 5, power supply box body 6 and is connected plate 7; Power supply box body 6 upper sides of hollow type rectangular parallelepiped box structure dig and are shaped on the battery case 5 that can smoothly put into lithium battery; The recessed formula structure of one end upside of power supply box body 6 is shaped on the connection plate 7 of conduction; The medial extremity that connects plate 7 is communicated with the electrode of battery 1, and the outboard end general formula that is electrically connected is shaped on the hook pin 4 of tabular L type; The place, four end angles of the bottom side of power supply box body 6 is shaped on isostructural four respectively and inserts pin 2, is used for being inserted in the corresponding jack of ammeter; Be shaped on the welding pin 3 that is used for source of welding current lead-in wire of two same structures on the bottom side of power supply box body 6 away from the vertical structure in end that connects plate 7; During use, both can with the 6 smooth placements of power supply box body and with the corresponding socket insertion on each pin alignment ammeter.
