The first and second connectors 250 and 280 are electrically connected to the printed circuit board 240 or the flexible printed circuit board 270 by lead wires 251 and 281. The lead wires 251 and 281 may be mounted by connecting terminals of the printed circuit board 240 or the flexible printed circuit board 270 and soldering or SMT (Surface Mounting Technology), for example.

The first and second connectors 250 and 280 are engaged with each other. Connection pins 252 and 282 are formed on the surfaces of the first and second connectors 250 and 280 which are engaged with each other to electrically connect the first and second connectors 250 and 280. For ease of assembly, the insertion force required when the first and second connectors 250 and 280 are coupled is weak, and the pressing force required to separate the first and second connectors 250 and 280 is designed to be strong .

A reinforcing plate 290 is mounted on one surface of the flexible printed circuit board 270, that is, on the opposite surface of the surface on which the second connector 280 is mounted. The reinforcing plate 290 has a predetermined thickness to reinforce the strength of the mounting surface 271 of the second connector 280. The reinforcing plate 290 may be formed of, for example, PC (Poly Carbonate) or STS (Stainless Steel).

The reinforcing plate 290 is disposed to reinforce the strength of the mounting surface 271 so that the coupling between the flexible printed circuit board 270 and the second connector 280 is separated by the flow of the flexible printed circuit board 270 Can be solved. In addition, since the insertion force is distributed to the reinforcing plate 290, breakage of the flexible printed circuit board 270 and the second connector 280 due to the concentration of force can be prevented.

Since the lead wire 281 and the electric circuit are disposed around the second connector 280, the width of the mounting surface 271 of the second connector 280 and the reinforcing plate 290 covering the same is wider than that of the second connector 280 . When an external force due to an impact or the like is applied to the end portion of the reinforcing plate 290, the reinforcing plate 290 may be heard and the second connector 280 may be detached from the first connector 250.

The support portion 260 is formed to protrude from the first connector 250 toward the end of the reinforcing plate 290 to support the end portion of the reinforcing plate 290. By supporting the reinforcing plate 290 by the supporting portion 260, the flow of the reinforcing plate 290 is restricted, and the detachment of the connector due to the external force can be prevented.

The support portions 260 are formed to protrude toward the reinforcing plate 290 on both sides in the width direction and / or the longitudinal direction of the first connector 250. The first connector 250 and the support portion 260 may be formed to completely cover the second connector 280 when the first and second connectors 250 and 280 are coupled to each other. According to the above-described structure, the joint portions of the first and second connectors 250 and 280 are shielded, and connection failure and malfunction due to penetration of foreign matter can be prevented.

The end of the support portion 260 may be formed to be in surface contact with one surface of the reinforcing plate 290 or the mounting surface 271. The support portion 260 may be formed on a surface on which the lead wire is disposed so as to cover the lead wire of the first connector 250. [ The width of the support portion 260 may be equal to or wider than the width of the reinforcing plate 290 and the lead wire. According to the above structure, the support portion 260 supports both ends of the reinforcing plate 290, and the flow of the reinforcing plate 290 can be restricted even if an external force is applied to the end portions of the reinforcing plate 290.

Further, since the support portion 260 is disposed so as to cover the lead wire of the first connector 250, the mounting area of the connector is not affected, so that the prevention of the detachment of the connector and the mounting efficiency can all be satisfied.

Figs. 7 and 8 are sectional views respectively showing another example of the connector shown in Fig.

Referring to FIGS. 7 and 8, the mobile terminal according to the present embodiment has the same configuration as the mobile terminal 100 described above except for the support portion 260. Therefore, the following description will focus on another example of the support portion 260. FIG.

Referring to FIG. 7, the support portion 260 'includes an inclined portion 261' and a reinforcement portion 262 '.

The inclined portion 261 'is formed so as to project obliquely toward the end of the reinforcing plate 290 in the first connector 250. The inclined portion 261 'may be formed to extend from the reinforcing portion 262' or protrude directly from the side of the first connector 250, as shown in FIG.

The reinforcing portion 262 'extends from the inclined portion 261' and is made thicker than the inclined portion 261 'to reinforce the strength of the supporting portion 260'. The reinforcing portion 262 'may protrude from the side surface of the first connector 250 or extend from the inclined portion 261' as shown in the figure.

The lead wire 251 may be disposed on the bottom surface of the reinforcing portion 262 '. When the first connector 250 and the support portion 260 'are integrally formed and the lead wire 251 is injection-molded on the bottom surface of the reinforcing portion 262', the assembling convenience of the first connector 250 is improved .

8, the support portion 260 '' may be formed to protrude to a predetermined height with a step around the first connector 250. The support portion 260 '' may be formed to completely cover one side of the reinforcement plate 290 .

The lead wire 251 may be disposed on the bottom surface of the support portion 260 ", as described above with reference to Figure 7. The support portion 260 "is formed only of the reinforcement portion without the inclined portion, The manufacturing process of the first connector 250 is simplified and the assembling convenience can be improved. In addition, when the contact area between the support portion 260 '' and the reinforcing plate 290 is larger than that of the first connector 250 ' The reinforcing plate 290 can be stably supported, and the connector can be prevented from being separated from the external force.

The mobile terminal described above is not limited to the configuration and method of the embodiments described above, but the embodiments may be configured by selectively combining all or a part of the embodiments so that various modifications may be made.
