Description

A magnetic switch technical field:

The invention relates to the technical field of switch control mounting, and particularly relates to a magnetic switch which can be used for products such as books, greeting cards, bags, boxes and the like. ·

BACKGROUND OF THE INVENTION - Control switch devices are widely used in people's daily life. The usual control switch device uses a mechanical contact method to connect the lines, and the deformation of the contact point in the control device is controlled by an artificial external force to make it in the line. The connection contacts are connected. Since such switches require artificial application of external forces, they are often limited in their use. Many people are now designing new control switch devices to solve such problems, most of which take advantage of the characteristics of magnetic tools. For example, the Chinese patent specification with the patent number: 88205007. 9 discloses a "button type magnetic switch", which eliminates the structure of the current common switch device using a spring, which uses the principle of a permanent magnet to realize the circuit guide. The electromagnetic sheets can be in contact with the respective contacts, and finally the switching or switching of the lines is realized.

On the other hand, with the development of electronic technology, many products are equipped with electronic devices such as electronic books, electronic greeting cards, and electronic school bags. All of these electronic products require the use of switches, but the traditional switch is difficult to implement the automatic start function, which requires manual start-up, which is inconvenient for use.

SUMMARY OF THE INVENTION - It is an object of the present invention to overcome the shortcomings of the above-mentioned products and to provide a magnetic switch that is convenient to use. This switch uses a magnetic force to achieve an automatic opening circuit.

The invention is realized by the following technical solutions: the switch comprises two units respectively placed on different parts of the carrier body, and the two units are attracted to each other by the suction force generated by the self-magnetic material to electrically connect the circuit. That is, the circuit is turned on in a contact state by two mutually attractable units. The conduction mode in the technical solution adopts two modes. One of the modes is as follows: One of the two units in the switch includes a conductive member and a magnet, the magnet is fixed to the carrier by a conductive member, and the conductive member is connected to one electrode of the circuit; the other unit also includes a conductive member magnet The magnet is fixed to the carrier by a conductive member, and the conductive member is connected to the other electrode of the circuit; the two units are magnetically attracted to contact by the self magnet, so that the conductive members on the two units form an electrically conductive contact. In this mode, the two units use the same structure and are respectively connected to one of the electrodes in the circuit. When the two are in contact, the circuit is turned on.

Another conduction mode is: one of the two units includes a conductive member and a magnet, the magnet is fixed on the carrier by a conductive member; and the other unit includes two electrode blocks that are spaced apart from each other. The electrode blocks made of the magnet attracting material are respectively connected to the two electrodes in the circuit; when the two units are attracted by magnetic attraction, the conductive members on one of the units simultaneously contact the two electrode blocks on the other unit, so that the two The electrode blocks form an electrically conductive contact. In this mode, one of the cells passes through two electrode blocks as two electrodes in the circuit, and the other unit acts as a conductor connecting the two electrode blocks, thereby achieving circuit conduction.

The carrier is an article on which the present invention is mounted, for example, a printed matter having a plurality of pages, and two of the switches are respectively fixed on two adjacent pages of the printed matter. When the user flips the page, the switch is also triggered.

The invention utilizes the mutual attraction characteristics of the magnetic force to control the line switch. When in use, the two units in the switch are in contact and the lines are connected; when the two units are separated, the circuit is disconnected. The invention has simple structure and convenient use, and can be especially applied to products with multiple pages such as an e-book or an e-card. At the same time, it is also possible to automatically trigger the circuit by opening and closing the opening at the opening of the product such as a bag, a box or the like having an electronic circuit. In addition, since the present invention utilizes a magnetic force to activate the line switch, it can be concealed and mounted inside the product. BRIEF DESCRIPTION OF THE DRAWINGS:

Referring to Fig. 1, the carrier 1 in this embodiment is a foldable greeting card. The two units 21, 22 of the switch 2 are respectively arranged on the two folding faces 11, 12 of the greeting card.

One of the two units 21 of the above switch 2 includes a conductive member 211 and a magnet 212 which is fixed to the carrier 1 by a conductive member, and the conductive member is connected to one electrode of the circuit. The conductive member 211 forms a sandwich housing in which the magnet 212 is sandwiched. Similarly, the other unit 22 also includes a conductive member 221 magnet 222 which is fixed to the carrier 1 by a conductive member 221 and which is connected to the other electrode of the circuit. When the two units 21, 22 of the switch 2 are close together, they are brought into contact by magnetic attraction, and the conductive members 211 on the two units 21, 22 form an electrically conductive contact. The circuit is triggered.

FIG. 1 is a schematic view of the embodiment. In actual production, most of the two units 21 and 22 of the switch can be disposed in the interlayer of the greeting card pages 11 and 12, and only the conductive members 211 and 221 are exposed on the surface of the greeting card. Forming a conductive contact. In this way, the switch can be concealed in the carrier 1 without affecting the aesthetics of the product.

See Figure 2, which is a circuit diagram of a specific application of the present embodiment 1. The circuit 3 is in an electronic greeting card Sound circuit. After the two folded faces 11 and 12 of the greeting card are opened, the two conductive members are separated, and the switch 2 is in an open state. At this time, after receiving the signal, the control chip 31 will trigger the horn 32 to sound and the illuminator 33 to emit light. When the greeting card is folded, the two conductive members are in contact, and the switch 2 is in a closed state. At this time, the control chip 31 receives the signal and issues a control command to stop the horn 32 from sounding and the illuminator 33 to be extinguished.

Referring to Figures 3 and 4, in the present embodiment, one of the two units of the switch 2 includes a conductive member 211 and a magnet 212 fixed to the page of the greeting card by the conductive member 211; the other unit 22 includes Two mutually spaced electrode blocks 223, 224. The electrode blocks 223, 224 are generally made of a material that can be attracted by a magnet. The two electrode blocks 223, 224 are respectively connected to the two electrodes in the circuit; the two units 21, 22 are attracted by magnetic attraction, wherein the conductive member 211 on the unit 21 simultaneously contacts the two electrode blocks 223, 224 on the other unit 22. The two electrode blocks 223, 224 are brought into electrical contact.

The two electrodes of the switch in this embodiment are disposed in one of the units 22. The two electrode blocks 223, 224 of their own are turned on by the conductive member 211 in the other unit 21.
