The shell 3 and the slip lid 2 of telephone set are made of plastics, and plastic material should be chosen that can slide between these two parts a kind of.In addition, two-part surface is polishing fully preferably, and housing parts 3 considers that Electromagnetic Compatibility should be able to plate metal, for example aluminizes.At last, these two parts should be stablized on mechanical performance.These performances can be obtained by the Merlon (PC) that employing is added with polytetrafluoroethylene (PTFE).Add this class material in order that make these two parts have " self-lubricating function ".

Can see from Fig. 1～3, telephone set 1, thereby shell 3 and slip lid 2, slightly bending, and shell 3 also has display part 4, for showing that for example called number, alphanumeric number, phone repertory, collection of letters situation and battery condition are used.

Slidably property between shell 3 and the slip lid 2 reaches in above-mentioned most preferred embodiment like this: respectively there is a sidewall 16 both sides of slip lid 2 (see figure 7)s, the top of sidewall 16 is flanges 17, the crank axle (not shown) of going for a stroll is slightly crooked, inwardly is parallel to the horizontal expansion of telephone set.Corresponding therewith, telephone outer shell 3 is formed with sweep corresponding guide rail 35.In other words, the displacement between slip lid 2 and the shell 3 is carried out along the figure arc.This can clearly be seen that from Fig. 1～3.Can also see that from Fig. 1～3 curved portions is less because slide institute along radius of a circle than the length of telephone set greatly due to.

In the position shown in the figure 1, slip lid 2 covers the whole operation face 5 of telephone set.Have when calling out, slip lid 2 can be slided into position shown in Figure 2 and respond, at this moment can touch first group of action button 6.In addition, have only slip lid 2 sliped off and could respond described calling, this is about to explanation after a while.In described most preferred embodiment, call out also and can be responded by means of volume button (last or following).Volume button is configured in a side of telephone set, and is not shown.

First group of action button 6 can comprise call response button, termination of a call button and the control telephone set repertory control button through programming repertory facility.Slip lid 2 slides into and just can touch last when further sliding behind the position shown in Figure 3 and organized button.Last group button mainly comprises the alphanumeric button of calling out or phone programming being used.

It can also be seen that from Fig. 1～3 slip lid 2 has a bump 39, have one or more eyelets that allow speech pass through above.Microphone 10 is contained in below the slip lid 2 interior bumps 39.

Fig. 4 shows the band microphone, how gentle matter printed circuit board (PCB) assembled before the slip lid 2 of packing into the member 34 that contacts conductor.Gentle matter printed circuit board (PCB) (PCB) 8 has two conduction printing system paths 15, and its length roughly is equivalent to the length of slip lid 2.When packing in the slip lid 2, PCB8 extends along the direction that telephone set slides.Microphone 10 is contained in the base of gentle matter PCB 8, is electrically connected with two conductive paths 15 through electrical filter 32.Rubber packing spare 33 loose grounds are enclosed within and play the mechanical protection effect on the microphone 10, and foamed plastics member 9 is contained in gentle matter PCB 8 rear sides and is protecting filter 32.Foamed plastics 9 has a flap valve around the deflection of the edge of PCB, is covered with the front of PCB.Like this, 9 deadenings of seal 33 and foamed plastics member.

Plastic plate 12 (for example Merlon) has two cannelures 13 for the side that back side guard plate 14 is covered scribbles binding agent on the plastic plate 12.When removing back side guard plate 14, plastic plate 14 can (as plywood) be attached on the gentle matter PCB, thereby can touch conductive path by groove 13.Plastic plate 12 is wideer than gentle matter PCB 8, thereby plastic plate 12 part that scribbles binding agent is outstanding along gentle matter PCB 8.The ledge of these band binding agents is used for installing element 34.

Then, load onto microphone seat 11, the microphone case 18 of microphone seat 11 is set on the microphone 10 that is in the microphone packing ring 33.Assembly that assembles or member 34 install to slip lid 2 and are formed with for holding the inboard of member 34 together with the recess 37 of microphone.Member 34 cover fits over together on the guide finger (not shown, but represent with chain-dotted line 36), thereby member 34 accurately is seated in the recess 37 of slip lid 2, and member 34 is fixed up.Fixing situation is such: microphone case 18 is packed into together with microphone seal 33 in the recess 37, and gentle matter PCB 8 adds with label 12 and adheres to recess 37 inner surfaces.Correct when in place, protectiveness label 12 and microphone seat 11 are ultrasonically welded to slip lid 2 some position that can directly engage, thereby have strengthened situation about adhering to.

Docking apparatus 20 shown in Fig. 6 is got the position shown in Figure 10 in the most preferred embodiment of telephone set of the present invention.Docking apparatus 20 has two piston shoes 21 to slide along corresponding conductive path 15 when slip lid 2 slides, thereby also guarantees good electrical connection although slide.We find, even slip lid 2 also can transmit the signal of telecommunication when sliding almost silently.

Docking apparatus 20 has a microswitch driver 29 in piston shoes 21 sides.Slip lid is in when closing the position, and drive pin 38 cooperatings on microswitch driver 29 and the slip lid 2 press down microswitch driver 29, engages with another contact portion 31, thereby circuit pathways is connected.Like this, because the microswitch closure, thereby when can detect slip lid 2 places in the position shown in the figure 1.When the current path in the microswitch interrupted, need not other button of actuating just can responding call.Then, the making current path just can finished call.Microswitch has the contact arm 30 of two machine PCB that answer the call, and each piston shoes 21 then has only a contact arm 30.

The rebound performance of piston shoes 21 has compensated the variation of spacing between slip lid 2 and the shell 3.Piston shoes 21 and microswitch driver 29 are configured to and patch spring, and the palladium-nickel alloy that plates 20 micron thickness is covered with the hard gold of 2 micron thickness again.Conductive path 15 (slip film) is coated with the hard gold of 5 micron thickness.The resistance to wear and the reliability that are electrically connected have been guaranteed like this.

As can see from Figure 8, the both sides, rear section of shell 3 are equipped with hole 27 for each base portion part 26 of holding when assembling with clamping elastic component 25.Here the top of shell 3 removal.The arm end 24 of each elastic component 25 stretches out by a hole of shell 3, enters in the guide rail 35, and described member is as in the recess 19 on the elastic protrusion embedding flange 17.Like this, projection 24 and three recesses 19 have been determined three positions shown in Fig. 1,2 and 3.Certainly can also between these three positions, decide other position in addition, but three positions when sliding, slip lid detect easily.Projection 24 and three recesses 19 have been determined three positions shown in Fig. 1,2 and 3.Certainly can also between these three positions, decide other position in addition, but three positions when sliding, slip lid detect easily.Cooperating between projection 24 and three recesses 19, itself be not sufficient to prevent that slip lid 2 from extracting out from shell 3.Therefore be equipped with crossette or scotch 23 for guide rail 35, by with slip lid 2 on locking cooperating of boss prevent that slip lid and shell from separating fully.

But for safety, make slip lid 2 possess certain elasticity, do not cause slip lid 2 strains when making its sufficient to guarantee slip lid 2 and its sidewall 16 is deviate from from the guide rail on the telephone outer shell 3 together with slide rail part 17 with respect to telephone outer shell 3 distortion.Therefore, scotch 23 is formed with spigot surface, makes slip lid 2 be not difficult once more in place together with locking boss 22.

Telephone set is equipped with the timer (not shown) of band time-delay, in order to make the time that the response of calling out is postponed to be equivalent to several seconds when the responding call by slip lid 2.Can make user's this calling of interruption/termination before conversation like this.

Fig. 9 shows slip lid 2 and is in that treating once more inwardly slides and makes it and slide into position on the scotch 23.Can see that each internal part (button, PCB, docking apparatus etc.) is not packed in the telephone outer shell 3 as yet.Lining pin 28 is supported slip lid by the time spent of doing of telephone set front upward pressure.This is avoided separating because of pressurized.

Figure 10 shows the position of docking apparatus 20 under operating surface 5.Except that not being with slip lid 2, the telephone set of Figure 10 is not also mixed button, PCB etc.

Slip lid 2 is flange and be equipped with the discrete guide finger that embeds shell 3 guide rails and replace flange 17 continuously also.In addition, also guide rail can be located on the slip lid 2.

For the profile with the soft slyness of telephone set more clearly shows, some accompanying drawing has added some auxilliary moving-wire bars.In the above-mentioned most preferred embodiment of telephone set of the present invention, conductive path is placed on the slip lid, also should be all right but be located on the telephone outer shell, and at this moment docking apparatus is contained in the slip lid.In the case, conductive path just came out when slip lid unloaded, and this brings some shortcoming.

The present invention includes specification of the present invention obviously or the new feature that forms of comprehensive disclosed each combination of features, whether do not have this new feature relevant with the present invention or can not reduce the order of severity of above-mentioned any or all of problem.

From above-mentioned explanation, obviously the experts in present technique field know, can carry out various modifications to the foregoing description without departing from the scope of the invention.
