Description
The utility model relates to the card plug-in type watt-hour meter of prepayment electric expense.
The card plug-in type watt-hour meter of existing prepayment electric expense, be with the design of the read-write interface of card form in watt-hour meter, the plug receptacle of its paying card is positioned at middle part, watt-hour meter front, and outside the watt-hour meter shell, adds dust cover again.Need take off dust cover earlier during use, insert the paying card again and connect read-write interface, after read-write finishes, extract card out, finish the operation of pre-payment electric weight.This watt-hour meter because the plug receptacle of card is located at the middle part in the watt-hour meter, is easily brought dust and other objectionable impuritiess into when inserting card.In addition, being provided with of dust cover increased running program, and also loses easily, and loses dustproof effect.
Given this, the purpose of this utility model is to provide a kind of simple in structure, card plug-in type pre payment watthour meter of being difficult for bringing into dust and other noxious materials when using.
Card plug-in type pre payment watthour meter of the present utility model (referring to accompanying drawing), comprise watt-hour meter (1) and the plug receptacle (9) of read-write interface (3) is arranged, it is characterized in that above-mentioned read-write interface stretches out watt-hour meter shell (2), above-mentioned plug receptacle has the coulisse (7) that is installed in the shell outside
Above-mentioned coulisse (7) is rectangular slab, its lateral cross section star
Shape.
Above-mentioned shell (2) is a watt-hour meter lower side shell, and read-write interface (3) is arranged on it, read-write switch (4), hummer hole (5).
The utlity model has following advantage.
One, the utility model is arranged on the card insert interface either party in the watt-hour meter outside, when particularly being arranged on the shell outside, below, make read-write interface towards the below, when pulling and pushing card, both made and brought materials such as dust into socket, dust etc. can not enter watt-hour meter yet, guarantee that its read-write portion and inner structure thereof are not contaminated.
Two, individual chute vane of the utility model is contained in the watt-hour meter shell, utilizes the watt-hour meter shell to constitute the card insert interface, and removes dust cover, its simple structure, and cost is low, and is easy to use.Because the interface gauge is little, can not influence the good looking appearance of watt-hour meter.
Below, use embodiment and accompanying drawing thereof again, the utility model is described in further detail.
