In addition to the antenna for talking and the like, a broadcast signal reception antenna 116 may be additionally disposed on the side of the terminal body. The antenna 116, which forms part of the broadcast receiving module 111 (see FIG. 1), can be installed to be able to be drawn out from the terminal body.

A power supply unit 190 for supplying power to the portable terminal 100 is mounted on the terminal body. The power supply unit 190 may be built in the terminal body or may be detachable from the outside of the terminal body. A rear cover 104 mounted on the rear case 102 of the terminal body for preventing detachment of the power supply unit 190 and protecting the power supply unit 190 from the outside is further provided .

The rear cover 104 may partially cover the rear case 102 or cover the entire rear case 102 as shown in FIG. 2B. And an opening for exposing the camera 125 or the sound output unit 154 to the outside when covering the front surface of the rear case 102.

4 is a cross-sectional perspective view showing a structure for electrically connecting an antenna 116 as an external electronic device and a printed circuit board 210 inside the mobile terminal 100. The case 103, the printed circuit board 210, A contactor 220, an external electronic device 116, and a metal rod 240 are shown.

2A and 2B, the case 103 protects the electronic components mounted in the case 103. The front case 101 and the mobile terminal 100 constitute the front surface of the mobile terminal 100, And a rear case 102 constituting a rear surface of the rear case 102.

Recently, a mobile terminal 100 with a waterproof function has been introduced, and a sealing member such as a gasket may be provided at a coupling portion between the front case 101 and the rear case 102 so that water can not penetrate into the inside thereof . A gasket may be provided to prevent water from penetrating into a portion exposed to the outside through the opening of the case 103, such as a camera or a button, in addition to the joining portion of the front case 101 and the rear case 102.

The printed circuit board 210 is a plate-shaped member which is disposed inside the case 103 and has a predetermined circuit pattern. An electronic component is mounted on the printed circuit board 210 to exchange signals between the electronic components through the circuit pattern.

The external electronic device 116 is an electronic device coupled to the outside of the case 103 and is electrically connected to the internal printed circuit board 210 and the electronic component through the case 103. It is convenient to use the device in the case of a device which is detachably attached or shipped to the user outside the case 103, rather than being disposed inside the case 103. An example of an external electronic device is an antenna 116 that is elongated and contracted in the longitudinal direction and needs to be pulled out repeatedly.

Particularly, in the case of the mobile terminal 100 having the above-described gasket and having a waterproof function, the necessity of such an external electronic device is increased. When the antenna is mounted so as to be pulled out from the inside of the case, there is a problem that the pulling-out is difficult due to the frictional force of the gasket, the gasket is worn, and the waterproof function is deteriorated.

2B, the electronic device repeatedly in and out like the antenna is coupled to the outside of the case 103 and passes through the case 103 through the metal rod 240, And is connected to the printed circuit board 210 or the electronic component.

The metal rod 240 is a member that is electrically connected to the external electronic device at one side and the other side is connected to the printed circuit board 210 through the case 103. Through the case 103, And a gasket (245) disposed between the metal rod (240) and the case (103) to prevent water from penetrating into the inner space.

3, a metal pad 21 is provided on the printed circuit board 15 for connection between the metal rod 40 and the printed circuit board 15, And the end of the rod 240 is in contact.

However, in such a connection method, there is a problem that the metal rod 40 and the metal pad 21 are separated from each other due to an external impact and the connection is broken. Further, since the space inside the case 103 is further required by the thickness of the metal pad 21, the efficiency in terms of utilization of the internal space of the case 103 is reduced.

In order to solve such a problem, in the present invention, a through hole is formed in the printed circuit board 210, and the contact is connected to the metal rod 240 using the contactor 220 disposed on the side wall of the through hole. This connection structure does not need to have the metal pads 21 above the printed circuit board 210, so that the thickness can be reduced and contact along the periphery of the metal rod 240 increases the reliability of the connection.

5 is a perspective view illustrating the contactor 220. The contactor 220 includes a contact portion 221 formed on the inner side of the through hole along the side wall of the through hole and a contact portion 221 extending from the contact portion 221 to the printed circuit board 210, And an engaging portion 223 that extends further to the surface of the engaging portion 223.

The contact portion 221 is formed along the side wall at the inside of the through hole and is substantially in contact with the metal rod 240 to be electrically connected. The contact portion 221 may be closely attached to the side wall of the through hole, but may protrude toward the center of the through hole rather than the side wall to match the size of the metal rod 240, as shown in FIG.

The shape of the contact portion 221 may change when the metal rod 240 is inserted, and the size of the ring may vary. That is, when the contact portion 221 is formed in the shape of a leaf spring, the metal rod 240 can be stably coupled to the metal rod 240 due to its elasticity while changing its shape upon insertion.

5 is a perspective view showing the shape of the contactor 220 of the present invention, and the leaf spring structure is disclosed. And a cutout portion 225 formed parallel to the depth direction of the through hole. The cutout portion 225 divides the contact portion 221 into a plurality of pieces. The shape of the contact portion 221 divided by the cutout portion 225 is changed when a force is applied to each piece, unlike the case of a single member. That is, each cut-out portion 225 functions as a leaf spring.

The piece divided by the cutout 225 changes its shape to correspond to the metal rod 240 when the metal rod 240 is inserted and is fastened to the metal rod 240. The metal rod 240 inserted by the elasticity of the leaf spring does not easily fall out and the contact structure is not separated by an external impact.

Further, since the metal rod 240 is coupled with the contactor 220 along the circumference of the metal rod 240, the contact area is wider than that of the conventional metal pad 21, and the reliability of connection is high.

The engaging portion 223 is configured to stably fix the contactor 220 to the printed circuit board 210 and extends from the end of the contact portion 221 to the surface of the printed circuit board 210, And is fixed to the surface of the substrate 210. The contactor 220 is coupled to the printed circuit board 210 without being detached by the coupling portion 223.

The engaging portion 223 may be inclined toward the through-hole to guide the metal rod 240 to be inserted into the contact portion 221.

The electronic connection between the external electronic device 116 disposed outside the case 103 of the mobile terminal and the printed circuit board 210 disposed on the inside is performed on the printed circuit board The thickness of the electrical connection structure between the external electronic device and the printed circuit board 210 can be reduced by the contactor 220 and the metal rod 240 passing through the printed circuit board 210.

The inner space can be further utilized, and the thickness can be reduced, so that the mobile terminal can be implemented more slimly.
