Description

A kind of fixed telephone

Technical field

The utility model relates to a kind of telephone device, relates in particular to a kind of fixed telephone with independent receiver.

Background technology

It all is to adopt the hook switch mode basically that present common on the market fixed telephone is hung up mode: the hook switch mode is to adopt general dpdt double-pole double-throw (DPDT) or six pin biserial PCB terminals, as shown in Figure 1, on telephone set, place take-up button 102 of Position Design of receiver, when receiver is placed on assigned position, take-up button 102 is depressed, take-up button 102 pressing hook switch mechanisms 101 cause hook switch mechanism 101 and internal circuit to disconnect, thereby telephone set are hung up.When receiver is picked up, hook switch mechanism 101 stressed reducing, it can utilize the spring of self inside that take-up button 102 is lifted, and connects internal circuit, thereby realizes the connection of telephone set.

Adopt the telephone set of hook switch mode to have following defective: 1, very high to the quality requirement of hook switch, in case the elastic force of hook switch is bigger than normal, perhaps displacement can not reach requirement, and this kind mode will lose efficacy.2, relatively stricter for the height dimension required precision of take-up button, may or use wearing and tearing to cause hook switch not press tightly or lost efficacy because of mismachining tolerance in actual applications.3, must reach the purpose that hook switch and internal circuit are disconnected owing to depress the power of hook switch by the take-up button, require receiver must reach constant weight, otherwise can't hang up the telephone, this just need increase materials such as counterweight in handle, cause the increase of telephone set manufacturing cost.

The utility model content

The technical problem that the utility model solves is, a kind of fixed telephone is provided, the hook switch mode that overcomes existing control telephone set break-make to mechanical part make require high, and the defective of hook switch mechanism inefficacy easy to wear.

The technical solution adopted in the utility model is, described fixed telephone, comprise telephone body, receiver and conversation control circuit, described receiver is connected by cable or wireless device with described telephone body, the take-up button is arranged on the described telephone body, described conversation control circuit comprises phone connecting circuit, conducting resinl device, described conducting resinl device comprises covering the copper zone, be connected the conducting resinl of take-up button one end on the circuit board that is arranged on telephone set inside, connects with the telephone set battery after closing of the circuit circuit and the parallel connection of conducting resinl device.When receiver is depressed the take-up button, cover the copper zone on the conductive carbon point on the conducting resinl and the circuit board and fit, when picking up a receiver, conducting resinl is upspring automatically, makes to cover the disengaging of copper zone on conductive carbon point and the circuit board.

Adopt technique scheme, the utility model has following advantage at least:

Fixed telephone described in the utility model utilizes the copper zone of covering on conductive carbon point on the conducting resinl and the telephone set internal circuit board to fit and break away from, thereby has realized the disconnection and the connection of closing of the circuit circuit reliably.Simultaneously, the hook switch mode that has overcome existing control telephone set break-make is made the requirement height to mechanical part, and the defective of inefficacy easy to wear.For the hook switch mode, reduced the cost of telephone set to greatest extent at manufacture view, in addition, can make things convenient for follow-up design, debugging by adjusting its elastic force of Adjusting Shape of conducting resinl.

Embodiment

For further setting forth the utility model is to reach technological means and the effect that predetermined purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to the described fixed telephone that the utility model proposes, describe in detail as after.

In the concrete embodiment of the present utility model, the final assembly figure of fixed telephone as shown in Figure 2.Described fixed telephone comprises telephone body 201, receiver 202 and conversation control circuit.The internal structure of described fixed telephone has take-up button 301 as shown in Figure 3 and Figure 4 on the telephone body 201,

As shown in Figure 6, the conversation control circuit is made up of the operating circuit R of telephone set battery, closing of the circuit circuit, conducting resinl device K and other parts, in the conversation control circuit, connects with the telephone set battery after closing of the circuit circuit and the conducting resinl device K parallel connection.Conducting resinl device K comprises and is arranged on covering copper zone 401, be connected the conducting resinl 302 of take-up button 301 1 ends on the telephone set internal circuit board, can adopt flexible connection between conducting resinl 302 and the take-up button 301.

The center that faces a side of circuit board at conducting resinl 302 is provided with conductive carbon point 501, and as shown in Figure 5, conducting resinl 302 adopts silica gel to make, and is shaped as the regular shape that extends around the mind-set therefrom, such as being designed to horn shape.When hanging up 202 the time, receiver 202 is under the self gravitation effect, take-up button 301 is depressed, take-up button 301 produces deformation with conducting resinl 302 extruding, covering copper zone 401 on conductive carbon point 501 on the conducting resinl 302 and the circuit board fits, conducting resinl device K and telephone set cell circuit are connected, and are about to the closing of the circuit short circuit, thereby disconnect the closing of the circuit circuit; When picking up a receiver 202 the time, conducting resinl 302 is upspring automatically, the conductive carbon point 501 and the copper zone 401 of covering on the circuit board is broken away from, thereby the closing of the circuit circuit is connected.

The conducting resinl device is installed in fixed telephone, generally can be satisfied 300,000 times instructions for use.In order to make better the playing a role of conducting resinl, can in design, suitably adjust the thickness and the angle of inclination of conducting resinl, make the elastic force appropriateness of required pressure and conducting resinl, because the conducting resinl employing has plastic silica gel and makes, and the length of take-up button is scalable also, has made things convenient for the follow-up design of telephone set, debugging.

Explanation by embodiment, can be to reach technological means and the effect that predetermined purpose takes to be able to more deeply and concrete understanding to the utility model, yet appended diagram only provide with reference to the usefulness of explanation, be not to be used for the utility model is limited.
