Abstract

The utility model discloses a telephone which can realize on-hook function without mechanical linkage, which takes a magnetic-control switch instead of a traditional fork spring switch; a magnet (6) is arranged on one end of a handle (3); a dry reed pipe (8), corresponding to a magnet (6), is arranged inside a handle seat (5) of a base (1); the handle (3) rises and falls on the handle seat (5) to close and cut a dry reed pipe (8), thus to realize the telephone on-hook function. Because the switch does not have mechanical linkage system and failure rate is low, the lifetime of the telephone is lengthened, design freedom of the telephone is added, and process is simplified.

Description

Telephone

The utility model relates to the telecommunication technology field, especially a kind of telephone set of not controlling the dislodging machine by mechanical interlock.

According to the technical standard of the national Ministry of Posts and Telecommunications about the telephone set aspect, telephone set enters public telephone network as telecommunication terminal equipment, dislodging machine, ring must can be realized under no supplemental powered situation, send and talked about and basic function such as the number of sending out function that the machine function of wherein seting out is correctly to realize the prerequisite of all the other functions.The dislodging machine function of traditional telephone set is to utilize handle rising and falling on the handle set of telephone base, and mechanical switch---switch hook is realized by mechanical interlock control.This switch hook is easy to generate fault owing to use frequently, and when using moist material to enter telephone set from the opening of switch hook easily inner and cause the electrical property fault, thereby reduced the reliability of telephone set, influenced the life-span of telephone set.Someone attempts to replace switch hook with optoelectronic switch, but this method must be supplemental powered, thereby has lost feasibility.

Task of the present utility model provides does not a kind ofly control dislodging machine function by the mode of mechanical interlock control mechanical switch, under no any supplemental powered situation, still can be by handle rising and falling on the Telephone handset seat machine function that realizes seting out, to reach the reliability that both improves telephone set, the purpose that prolongs its life-span again.

In order to finish above-mentioned task, the technical solution adopted in the utility model is: replace switch hook to realize dislodging machine function with magnetic control system switch.This telephone set by base (1) and be loaded in it and the control circuit board of electronic component is housed, the button (2) that the handle (3) of receiver (4) and Electret condenser microphone (7) is housed and is contained in base (1) upper surface is formed, link to each other with the control circuit that is contained in base (1) with the talking and receiving circuit of elastic wire (9) handle (3).The feature of this telephone set is in the handle set of base (1) (5) inboard tongue tube (8) to be housed, at handle (3) magnetic circuit is housed---magnet (6), magnet (6) present position was corresponding when the installation site of tongue tube (8) was placed on the handle set (5) with handle (3); Like this, when handle (3) near or when leaving handle set (5) on the base (1), i.e. the disconnection or the closure of may command tongue tube (8) are through the conversion of the control circuit machine function of can seting out in fact.

Because the utility model adopts magnetic switch to replace switch hook, thereby failure rate is low, and the reliability of telephone set is improved greatly, has prolonged the life-span of telephone set; Because of its switch does not have mechanical linkage, increased the very big degree of freedom for the indoor design and the appearance design of telephone set, can simplify production technology, enhance productivity.

Fig. 1 is the front view of the utility model telephone set;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the circuit theory diagrams of the utility model telephone set.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Be welded on electronic component on the control circuit board and be installed in base (1) inner chamber by shown in Figure 3, button (2) is installed in Telephone set (1) upper surface by the telephone set routine.

By shown in Figure 2 with magnetic switch---tongue tube (8) is installed in the telephone set base (1) near the inner surface of handle set (5), and its position is corresponding with the position of installation magnet (6) in the handle (3); Magnet (6) is installed in the handle (3), Electret condenser microphone (7) is installed in an end of handle (3), receiver (4) is installed in the other end of handle (3), and the control circuit talking and receiving circuit of handle (3) is interior with being contained in base (1) with elastic wire (9) links to each other.

SW1 shown in Figure 3 is a magnetic switch---tongue tube (8), when the external magnetic field of no suitable intensity (200～1500 Gauss) is normally closed as the time spent, when handle (3) is placed on the handle set (5), owing to be contained in the magnet of handle (3) one ends---magnet (6) is near tongue tube (8), its the action of a magnetic field makes tongue tube (8) be in off-state, triode Q2, Q5, Q1 all end at this moment, and telephone set is in hook state; When handle (3) leaves base (1), that is handle (3) is when leaving handle set (5), the action of a magnetic field that does not have suitable intensity (200～1500 Gauss) owing to magnet this moment (6) and the distance that is in the tongue tube (8) on the handle set (5) greatly, make tongue tube be in closure state, that is SW1 connects, make triode Q2 conducting, and then Q5, Q1 conducting, make telephone set realize handoff functionality.

Remaining circuit as shown in Figure 3 partly is prior art, is omitted at this.

Claims

1, a kind of telephone set, it comprises:

Support (1), in the control circuit board of electronic component is housed, to realize that telephone set send words, is subjected to words, dislodging machine, ringer function;
