BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to portable telephone sets and data communication adaptors and, more particularly to a portable telephone set and a data communication adaptor used to build a mobile communication system that includes an information processing device.
Recently, portable telephone sets are being used not only for telephone communication but also used in combination with an information processing device for mobile communication. Accordingly, it is required that a portable telephone set be useful to build a mobile communication system.
2. Description of the Related Art
FIGS. 1A and 1B show a portable telephone set 10 according to the related art and how a mobile communication system is built using the portable telephone set 10.
The portable telephone set 10 has a connector 10a at the bottom thereof connectable to a connector of a cable.
FIG. 1A shows a mobile communication system 30 using an information processing device 20 not having a built-in data communication adaptor. The mobile communication system 30 is built using the information processing device 20, a cable 40 with connectors and a data communication adaptor 50. A connector 40a at an end of the cable 40 is connected to the connector 10a of the portable telephone set 10. A connector 40b at the other end of the cable 40 is connected to a connector 50a at an end of the data communication adaptor 50. The data communication adaptor 50 is inserted into a data communication adaptor accommodating unit 20a of the information processing device 20. A connector 50b at the other end of the data communication adaptor 50 is connected to a connector 20b at the rear end of the data communication adaptor accommodating unit 20a. 
Normally, the data communication adaptor 50 is inserted into the data communication adaptor 20a of the information processing device 20.
FIG. 1B shows how a mobile communication system 30A is built using an information processing device 20A having a built-in data communication adaptor. The information processing device 20A has a built-in data communication adaptor 60. The mobile communication system 30A is built using the information processing device 20A, the cable 40 with the connectors. The connector 40a at an end of the cable 40 is connected to the connector 10a of the portable telephone set 10 and the connector 40b at the other end is connected to a connector 60a of the data communication adaptor 60 built into the information processing device 20A.
A user who intends to perform mobile communication carries the portable telephone set 10 with himself or herself. In addition, the user carries the information processing device 20 (20A) and the cable 40 in, for example, a bag. If the cable 40 connected to the information processing device 20 (20A) is accommodated in the bag, a intensive force is applied to the joint between the cable 40 and the information processing device 20 (20A), causing the joint to be damaged. For this reason, the cable 40 is disconnected from the information processing device 20 (20A) while being carried.
Therefore, the user may leave the cable 40 behind at home since it is comparatively small. If the cable 40 is lost, mobile communication is impossible.
Another inconvenience is that, since the cable 40 should be connected to the portable telephone set 10 as well as to the information processing device 20 (20A), it takes time to build a mobile communication system.

In a portable telephone set in which a flipper is removable, the telephone set main body connector 118 is provided at the end of the flipper. In a portable telephone set in which a flipper is not removable, the telephone set main body connector 118 may be provided in the telephone set main body. That is, the connector 118 may constitute a part of the portable telephone set.
[Data Communication Adaptor 190 According to the Fifth Embodiment]
The data communication adaptor 190 shown in FIG. 14A has a construction as shown in FIGS. 16–20C.
The data communication adaptor 190 functions as a PCMCIA card. As shown in FIG. 18, the data communication adaptor 190 comprises a main body 191 and metal shield covers 192 and 193 that cover the upper and lower surfaces of the main body 191, respectively.
As shown in FIG. 19, the main body 191 is constructed such that a printed circuit module 195 is combined with a frame 194. The printed circuit module 195 is constructed such that a plurality of electronic parts 195b are mounted on the upper and lower surfaces of a printed circuit board 195a. The connector 122 connected to a portable telephone set is attached to the X2 end of the printed circuit board 195a and the connector 162 connected to the mobile information processing device is attached to the X1 end of the printed circuit board 195a. The frame 194 is configured to adapt for the printed circuit module 195. At the X2 end, the frame 194 is provided with arm portions 194a and 194b projecting in the X2 direction at the Y1 end and the Y2 end, respectively. A connector accommodating portion 194c accommodating the connector 122 is formed between the arm portions 194a and 194b. A incision 194d extending in the Z1–Z2 direction is provided between the arm portion 194a and the connector accommodating portion 194c, and a incision 194e also extending in the Z1–Z2 direction is provided between the arm portion 194b and the connector accommodating portion 194c. 
As shown in FIG. 20A, the shield cover 192 is provided with bent portions 192a and 192b at the Y1 and Y2 ends, respectively. The bent portions 192a and 192b are configured to be engageable with grooves 194f and 194g, respectively, provided at the Y1 and Y2 ends of the frame 194, respectively. The shield cover 193 is provided with bent portions 193a and 193b at the Y1 and Y2 ends, respectively. The bent portions 193a and 193b are also configured to be engageable with the grooves 194f and 194g, respectively, provided at the Y1 and Y2 ends of the frame 194, respectively. The shield covers 192 and 193 are electrically connected to the ground of the printed circuit module 195 and hermetically seal the printed circuit module 195.
The Z1 and Z2 ends of the incisions 194d and 194e are covered by respective portions of the shield covers 192 and 193. As shown in FIGS. 20A and 20B, the incision 194d and the shield covers 192 and 193 form the hole 190a. As shown in FIGS. 20A and 20C, the incision 194e and the shield covers 192 and 193 form the hole 190b. Each of the holes 190a and 190b has a relatively large depth A. The Z1 and Z2 end walls of the holes 190a and 190b have a relatively high mechanical strength since they are formed by respective portions of the shield covers 192 and 193. The holes 190a and 190b constitute a mechanical supporting mechanism as claimed.
To insure locking of the data communication adaptor 190, the arm portions 194a and 194b for locking of the data communication adaptor 190 are provided with recesses 194a1 and 194b1, respectively, at the inner surfaces thereof and also provided with rib portions 194a2 and 194b2, respectively, extending in the X1–X2 direction.
The data communication adaptor 190 is provided with the connector 122 at the X2 end thereof and the connector 162 at the X1 end thereof.
In order to perform mobile communication, the data communication adaptor 190 is connected to the flipper joint plate 117 of the telephone set main body 110 such that the connector 122 is connected to the telephone set main body connector 118. Subsequently, the data communication adaptor 190 connected to the telephone set main body 110 is inserted into the data communication adaptor accommodating unit 171A such that the connector 162 is connected to the connector 172 for connection with the mobile information processing device 170A. Thus, the mobile communication system 140B is built. The end of each of the shield covers 192 and 193 is electrically connected to the ground terminal (not shown) exposed in the data communication adaptor accommodating unit 171A of the mobile information processing device 170A.
As shown in FIG. 15, while mobile communication is being performed by the mobile communication system 140B, the telephone set main body 110 is located adjacent to the mobile information processing device 170A so that a predetermined moment M that acts to bend a joint between the connector 122 and the telephone set main body connector 118 is exerted on the joint. The moment M is given by (W, which is a sum of the weight of the telephone set main body 110, the force exerted on the telephone set main body 110 for operation thereof, an external force exerted on the telephone set main body 110)×(L which is the length of an arm extending from the joint between the connector 122 and the telephone set main body 118 to the center of gravity of the telephone set main body 110). The mechanical supporting mechanism as mentioned above bears the moment M so that a bending force is prevented from being exerted on the joint between the connector 122 and the telephone set main body connector 118.
A description will now be given of how the holes 190a and 190b provide a mechanical support.
When the mobile communication system 140B has been built as shown in FIG. 14B, the arm portion 230d is inserted into the hole 190a by the distance A so as to come into contact with the rear end thereof, and the arm portion 230e is inserted into the hole 190b by the distance A so as to come into contact with the rear end thereof, as shown in FIGS. 21A, 21B and 21C. FIGS. 21A, 21B and 21C also show that the rib portion 194a2 is engaged with the slit 230d1, the rib portion 194b2 is engaged with the slit 230e1, the recess 194a1 is engaged with the locking pawl 232, and the recess 194b1 is engaged with the locking pawl 233.
The moment M is born such that, as shown in FIG. 21C, an edge 193c of the shield cover 193 facing an exit of the hole 190a bears a base 230d2 of the arm portion 230d and an edge 192c of the shield cover 192 facing a rear end of the hole 190a bears an end 230d3 of the arm portion 230d, and, as shown in FIG. 21B, an edge 193d facing an exit of the hole 190b bears a base 230e2 of the arm portion 230e and an edge 192d facing a rear end of the hole 190b bears an end 230e3 of the arm portion 230e. In this way, the arm portions 230d and 230e are supported at two locations at the Y1 and Y2 ends, respectively.
As shown in FIG. 21A, the moment M is also born by the engagement of the rib portions 194a2 and 194b2 with the slits 230d1 and 230e1, respectively.
The metal shield covers 192 and 193 with which the arm portions 230d and 230e come into contact are known to have a relatively large rigidity. The distance B in the Z1–Z2 direction of the holes 190a and 190b is substantially identical to the thickness C of the data communication adaptor 190. Thus, the thickness of the arm portions 230d and 230e is relatively large. Accordingly, the mechanical support provided by the holes 190a and 190b is sufficient to bear the moment M. Thus, the joint between the connector 122 and the telephone set main body connector 118 is free from a bending force. Thus, the connection between the connector 122 and the telephone set main body connector 118 is prevented from being loosened. It is unlikely that the connector 122 and the telephone set main body connector 118 are bent while the connection is established or that terminals of the connector 122 or the telephone set main body connector 118 are damaged. Thus, the life of the connectors 122 and 118 is prevented from being excessively reduced.
[Variation of the Telephone Set Main Body]
FIG. 22A shows a telephone set main body 110A which is a variation of the telephone set main body 110 of FIG. 3. The telephone set main body 110A comprises the liquid crystal display unit 112, the operation buttons 113 and the antenna 114. A connector 350 is provided at the lower end of the telephone set main body 110A.
A connection adaptor 351 is used for the telephone set main body 110A. The connection adaptor 351 comprises the hinge mechanism 115 and the flipper joint plate 117. A connector 352 is provided on the upper end of the connection adaptor 351.
The connection adaptor 351 is used to connect the data communication adaptor 190 to the telephone set main body 110A.
The data communication adaptor 190 is connected to the telephone set main body 110A such that the connector 352 is connected to the connector 350 so that the connection adaptor 351 is electrically and mechanically connected to the lower end of the telephone set main body 110A. The data communication adaptor 190 is then connected to the flipper joint plate 117 of the connection adaptor 351. Thus, a data communication system as shown in FIG. 22B results. The mechanical supporting mechanism is operated as described already.
The present invention is not limited to the above described embodiments, and variations and modifications may be made without departing from the scope of the present invention.
