Abstract
The utility model relates to a magnetic induction switch of a telephone set, and the utility model is used for controlling the telephone start and the shutdown of the telephone. The utility model is composed of a magnetron and a permanent magnet block, and the magnetron and the permanent magnet block are respectively arranged on a telephone base and a telephone cover; when the telephone cover and the telephone base are closed, the position of the permanent magnet block on the telephone cover faces rightly with the position of the magnetron on the telephone base, and the magnetron is made to be in the action range of the magnetic field force of the permanent magnet; the magnetron is the sensor in the CPU of the telephone, and the magnetron is used for controlling the height of the electric potential of foot input. The utility model can be arranged on the telephones with various forms, and compared with mechanical buttons, the magnetron has sensitive response; The utility model has the advantages of no mechanical wearing and reliable working performance.
Description
The utility model relates to the startup and shutdown device of telephone set, is meant a kind of magnetic induction switch of telephone set particularly.
Telephone set as communication tool is used widely by people at present, the switch of telephone set was touch-tone in the past, promptly on telephone keyboard, be provided with special on ﹠ off switch, press this key closing of the circuit, click again and close, easier for the operation that makes telephone set afterwards, people design push switch, promptly establish a micromachine push-button switch on telephone base, when telephone set cover and support folding fastener fashionable, button is depressed, and telephone set is closed, and when cover when support is opened, button is upspring by himself spring, telephone set is connected, thereby the action of the start that will touch the button is integrated with the action of opening cover, has simplified operation.But it is on the folding telephone set that is connected with support each other that this switch can only be used in cover, and for being the telephone set that is slidingly connected each other, present widely used cover and support just be not suitable for, because the telephone set that is slidingly connected, cover is moving near level on support, cover can't be with the button down of push-button switch, the button that protrudes of can being upspring on the contrary blocks, and can't fasten with support.
The purpose of this utility model provides a kind of magnetic induction switch of telephone set, and it both can be installed in cover is on the collapsible telephone set that is connected with support, and can be installed in cover and support again and be on the telephone set that slidingtype is connected, thereby applied widely.
The purpose of this utility model is achieved in that
A kind of magnetic induction switch of telephone set, be used to control the startup and shutdown of telephone set, it is characterized in that: this switch is made up of a magnetron and a permanent-magnet block, described magnetron is installed on the support of telephone set, described permanent-magnet block is installed on the cover, and when cover and support closure, the position of the magnetron on the position of the permanent-magnet block on the described cover and the described support aligns, this magnetron is in the magnetic field force sphere of action of this permanent-magnet block, described magnetron is the transducer of the central processor CPU of telephone set, is used for the height of Controlled CPU input pin current potential.
Described magnetron can be a tongue tube.
Positive beneficial effect of the present utility model is:
Magnetic induction switch of the present utility model is that magnetron and permanent magnet are installed in respectively on support and the cover, utilize magnetic field force to control the connection and the shutoff of telephone set network by magnetron, and do not need connection and the shutoff of using mechanical button to control telephone set network, therefore, this switch is applied widely, can be installed in cover and support is on the telephone set that folds mutually, and can be installed in cover and support again is on the telephone set that slides mutually.And magnetron is sensitiveer than the mechanical button reaction, does not have the machinery shake, does not have mechanical wear, and service behaviour is more reliable.
Now in conjunction with the accompanying drawings the utility model is further described as follows with preferred embodiment:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the schematic diagram when cover and support are closed among Fig. 1;
Fig. 4 is the circuit theory diagrams of the utility model one embodiment, the fundamental diagram when being the mutual closure state of cover and support;
Fig. 5 is a cover and support state fundamental diagram when opening each other;
Referring to Fig. 1, Fig. 2, telephone set includes cover 1 and support 2, be slidingly connected mutually between cover 1 and the support 2, permanent-magnet block 101 is installed on the cover 1, magnetron 201 is installed, referring to Fig. 3, after cover 1 and support 2 fasten on the support 2, magnetron 201 positions of installing on permanent-magnet block of installing on the cover 1 101 and the support 2 align up and down, and magnetron 201 is in the magnetic field force sphere of action of permanent-magnet block 101.
Operation principle is as follows:
Fig. 4 shows the utility model one embodiment, and its magnetron can adopt tongue tube 3, and tongue tube 3 has two tongues 301,302, and tongue 301,302 usefulness electric conducting materials are made, and tongue 301,302 self all has certain elasticity.Tongue tube 3 is divided into open type, two kinds of closed types, the open type tongue tube promptly be when magnet when the tongue tube, tongue 301,302 closure that is magnetized, when magnet during away from tongue tube, tongue 301,302 leaves mutually by self elasticity, and the mutual action of the tongue of normally closed dry reed pipe is just in time opposite with said process.In the present embodiment, tongue tube adopts open type, as shown in Figure 4, when magnet 101 during near tongue tube 3, just the position of magnet on cover 1 101 and tongue tube 3 is to timing, two tongue contacts 301,302 in the tongue tube 3 are closed each other, and making CPU input pin 1N is high potential, thereby make the phone shutdown.Referring to Fig. 5, when magnet 101 during away from tongue tube 3, just the magnet 101 on the cover 1 not with 3 pairs of timings of tongue tube, two tongue contacts 301,302 of tongue tube 3 are left each other, the input pin 1N of CPU is an electronegative potential, makes the phone start, if the input pin 1N of CPU is defined as the electronegative potential shutdown, the high potential start only needs tongue tube among Fig. 43 and resistance R are got final product change place.
Claims (2)
1. the magnetic induction switch of a telephone set, be used to control the startup and shutdown of telephone set, it is characterized in that: this switch is made up of a magnetron and a permanent-magnet block, described magnetron is installed on the support of telephone set, described permanent-magnet block is installed on the cover, and when cover and support closure, the position of the magnetron on the position of the permanent-magnet block on the described cover and the described support aligns, this magnetron is in the magnetic field force sphere of action of this permanent-magnet block, described magnetron is the transducer of the central processor CPU of telephone set, is used for the height of Controlled CPU input pin current potential.
