Abstract
The normally closed dry reed pipe includes two reeds of ferromagnetic material packed inside a shell, and two pins connected to the reeds for leading them outside. The two reeds are parallel in the same direction and contact normally. When set in longitudinal magnetic field, the dry reed pipe has its two reeds equally magnetized, repulsed mutually and separated. The present invention may be used in circuit needing normally closed switch to simplify circuit and facilitate use.
Description
Technical field
The present invention relates to switch, particularly to the improvement of dry-reed tube switch.
Background technology
Tongue tube has a wide range of applications in electronic circuit, household electrical appliance, automation field.It is the reed of being made by two ferromagnetic materials that are encapsulated in the shell, and is connected with reed and its pin of drawing from shell is formed.Under the action of a magnetic field, the mutual adhesive of reed, the break-make of realization circuit.Existing tongue tube is a closure when external magnetic field is arranged, and disconnects during no magnetic field, is open type, when circuit design needs normally closed switch, itself can't realize, can only cause the circuit complexity by the conversion of circuit, uses inconvenience.
Summary of the invention
The object of the invention is to provide a kind of normally closed dry reed pipe, with convenient use at circuit.
The solution of the present invention is: normally closed dry reed pipe comprises the reeds that two ferromagnetic materials that are encapsulated in the shell are made, and is connected with reed and with its pin of drawing from shell, wherein, two reed cocurrent and parallels are provided with, Elastic Contact, and pin is drawn at an end of shell.
Advantage of the present invention is: because two reed cocurrent and parallels are provided with, when it was in longitudinally in the external magnetic field, the magnetization polarity of reed was identical, two mutually exclusive, disconnections of reed, when no magnetic field, reed has been realized normally off owing to Elastic Contact is communicated with.
Description of drawings
The invention will be further described with embodiment with reference to the accompanying drawings below.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the view in magnetic field.
1 reed, 2 shells, 3 pins, 4 magnet among the figure.
Embodiment
As shown in Figure 1, normally closed dry reed pipe comprises the reed 1 that two ferromagnetic materials that are encapsulated in the shell 2 are made, and be connected with reed 1 and its pin of from shell 2, drawing 3, it is characterized in that: two reed 1 cocurrent and parallel settings, Elastic Contact, pin 3 is drawn at an end of shell 2.
When no external magnetic field, because elasticity, two reeds 1 contact with each other, and be closure state this moment.
As shown in Figure 2, when placing magnet 4 at an end of tongue tube, when making it place longitudinally magnetic field, promptly the trend of the magnetic line of force is parallel to reed, this moment since the magnetization polarity of two reeds 1 identical, mutually exclusive, disconnect, reach the purpose of open circuit.
Design thus, tongue tube has been realized normally closed, when needing the circuit design of normally closed switch, can simplify circuit, has made things convenient for use.
