Abstract
The utility model relates to a key type switch, which is the wall type switch of the household appliance and comprises a shell body, an insulator, an electric conduction contact piece and a spring piece. The utility model is characterized in that the connection of a conducting wire does not use bolts to fasten, and the conducting wire is inserted between the electric conduction contact piece and the spring piece and can be automatically chucked. Mounting and dismounting are very convenient, connecting wire is firm, and the appearance is beautiful.
Description
The utility model relates to a kind of household electrical appliance switch, particularly is loaded on the piano key switch of wall.
The mode of connection of existing appliance switch all is with screw power line to be fastened on the wiring point, and the shortcoming of this mode of connection is: lead connects not firm, and is loosening easily, causes loose contact, even leads to the infringement to electrical equipment.In addition, existing switch case mostly is integral type, installs, dismantles inconvenience.
The purpose of this utility model provides a kind of novel piano key switch, and it adopts assembly type housing and card line pawl formula connecting line construction.
The purpose of this utility model is achieved in that it comprises housing, the switch insulation body, and conductive contact film is characterized in that: in the inner crawl space of switch insulation body, except that conductive contact film is housed, also adorned the spring leaf of the Ω shape of a band card line pawl.When the exposed part of lead inserts conductive contact film, the lead direction of insertion is pointed to consistent with an end of spring leaf, therefore insert very smoothly, and tightened, when lead is pulled outwardly by external force, because the outwards directed in opposite of travel direction and spring leaf one end, thereby lead is stuck, and is difficult for deviating from.
The said housing of the utility model is formed by outer shroud, center, keypad three part setting-ins.
The utility model is simple in structure, and the card line is firm, and dismounting is very convenient.
Details of the present utility model is provided by following examples and accompanying drawing thereof:
Fig. 1 is shell figure of the present utility model.
Fig. 2 is an internal structure schematic diagram of the present utility model.
Fig. 3 is the partial enlarged drawing of Fig. 2.
With reference to the accompanying drawings, housing of the present utility model is lifted mutually to close by outer shroud 8, center 7, key plate 6 and key 9 and forms.Switch insulation body 2 of the following connection of each key, center cavity one side of switch insulation body 2 is bumped into conductive contact film 3, spring leaf 4 has been installed at another angle of cavity, it becomes Ω shape, tip and conductive contact film 3 offset, be fixed with card line pawl 5 in the spring leaf outer end, the termination of card line pawl 5 is exposed switch insulation body 2 slightly.
When the exposed part of lead 1 when conductive contact film 3 inserts, lead points to along the tip of spring leaf 4 and enters, be not obstructed when therefore entering, after lead inserts, one end of conductive contact film 3 is done the time spent owing to elastic reaction blocks lead when lead is subjected to external pull, because an end of spring leaf 4 is opposite with the lead pull-out direction, thereby can not pull out, it is firm to reach connection.In the time of lead need being taken off, need only the termination of withstanding card line pawl 5, be about to spring leaf 4 and press, one end and lead are broken away from, just can take out lead with screw driver.
The utility model proves that through sampling test its performance adheres to specification, and can be made into simply connected, duplex, three sockets, and easy-to-connect is firm, and is durable in use, good looking appearance.
