Description
Technical field
The utility model is related to a kind of ammeter box, and in particular to a kind of single-phase four ammeter boxes.
Background technology
Single-phase electricity electricity box are a kind of household electricity ammeter boxes, but traditional household electric electricity box can not in the case of darkness
The quick reading that carries out is, it is necessary to optional equipment lighting device.
Utility model content
The purpose of this utility model is that there is provided single-phase four ammeter boxes of one kind, Neng Goushi for deficiency of the prior art
Existing plug-in card illumination.
To achieve the above object, the utility model discloses following technical scheme：
A kind of single-phase four ammeter boxes, including casing and transparent case lid, glass box are covered provided with plug-in card hole, and transparent case lid exists
Plug-in card hole inwall is provided with normally-closed contact, and in the case where electric card is inserted, normally-closed contact disconnects, and box house is provided with indicator lamp and photograph
Bright lamp, indicator lamp is connected with illuminating lamp, and illuminating lamp is in parallel with normally-closed contact, in the case where normally-closed contact disconnects, and illuminating lamp leads to
Electroluminescence, in the case where normally-closed contact is closed, illuminating lamp short circuit, only indicator lamp light.
Further, the illuminating lamp is arranged on the top of box house.
A kind of single-phase four ammeter boxes, have the advantages that disclosed in the utility model：
The utility model using normally-closed contact at plug-in card hole due to controlling circuit, and user inserts when needing to check reading
Enter electric card, normally-closed contact disconnects, illuminating lamp electrified light emitting is extracted after electric card, normally-closed contact closure, illuminating lamp short circuit is only indicated
Lamp lights, and is easy to user's reading under subdued light conditions.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the circuit diagram of indicator lamp illuminating lamp,
Wherein：
The transparent case lids of 1-, 2- normally-closed contacts, 3- plug-in cards hole, 4- indicator lamps, 5- illuminating lamps, 6- casings, L1- indicator lamps, L2-
Illuminating lamp, R1- resistance, K1- switches, K2- normally closed switch.
Embodiment
The technical scheme in the utility model embodiment will be clearly and completely described below, it is clear that described
Embodiment is only a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
Core of the present utility model is to provide a kind of single-phase four ammeter boxes, can realize that plug-in card is illuminated.
Refer to Fig. 1.
A kind of single-phase four ammeter boxes, including casing 6 and transparent case lid 1, transparent case lid 1 are provided with plug-in card hole 3, glass box
Lid 1 is provided with normally-closed contact 2 in the inwall of plug-in card hole 3, and in the case where electric card is inserted, normally-closed contact 2 disconnects, and the inside of casing 6 is provided with finger
Show lamp 4 and illuminating lamp 5, indicator lamp 4 is connected with illuminating lamp 5, and illuminating lamp 5 is in parallel with normally-closed contact 2, disconnected in normally-closed contact 2
In the case of, the electrified light emitting of illuminating lamp 5, in the case where normally-closed contact 2 is closed, the short circuit of illuminating lamp 5, only indicator lamp 4 light.
In a kind of embodiment of the present utility model, the illuminating lamp 5 is arranged on the top inside casing 6.
See Fig. 2.Indicator lamp L1 and resistance R1, switch K1, illuminating lamp L2 are sequentially connected in series in Fig. 2, normally closed switch K2 and illumination
Lamp L2 is in parallel, in the case where normally closed switch K2 is closed, and only indicator lamp L1 lights, when user inserts electric card, normally closed switch K2
Disconnect, illuminating lamp L2 connects luminous.
Compared to the content introduced in background technology, the utility model using normally-closed contact 2 at plug-in card hole 3 due to controlling electricity
Road, user inserts electric card when needing to check reading, and normally-closed contact 2 disconnects, the electrified light emitting of illuminating lamp 5, extracts after electric card, often
Closed contact 2 is closed, and the short circuit of illuminating lamp 5, only indicator lamp light, and are easy to user's reading under subdued light conditions.
Described above is only preferred embodiment of the present utility model, rather than its limitations；Although it should be pointed out that with reference to upper
Each embodiment is stated the utility model is described in detail, it will be understood by those within the art that, it still can be with
Technical scheme described in the various embodiments described above is modified, or which part or all technical characteristic are equally replaced
Change；And these modifications and replacement, the essence of corresponding technical scheme is departed from each embodiment technical scheme of the utility model
Scope.
