The window 40 is also configured to allow information to be input by the user's touch. Here, as a method for implementing the touch screen function in the window 40, a contact type capacitance type and a pressure type resistance type can be used.
In general, a step is formed on a side surface of a window made of a synthetic resin material in which the function of the touch screen is not realized, through stepped processing. The window is coupled in the direction from the rear surface to the front side of the front case so that the window is prevented from being released to the outside by the step difference.
However, as will be described below, the window 40 in which the touch screen function related to the present invention is implemented is formed of a plurality of layers, and a flexible circuit board for electrically connecting to the inside of the first body 10 is also processed The stepped machining is not easy. The window 40 related to the present embodiment is coupled to the front case 11 in the direction from the front to the rear of the front case 11 and is seated in the window seating portion 42.

The base layer 43, the electrode layer 44 and the protection layer 45 may be formed of a transparent material having a whole surface and the protection layer 45 may be formed for design purposes, May not be identified to the user.
The coupling part 50 is for coupling the window 40 to the front case 11 of the first body 10 and electrically connecting the window 40 and the ground formed on the first body 10.
The fastening part 50 according to the present invention may be constructed such that the front case 11 and the window 40 are attached to each other by a bonding agent or an adhesive film although the window seating part 42 of the front case 11 and the window 40 can be bonded by an adhesive or an adhesive film. Make it structurally concatenated.
The fastening portion 50 is formed of a conductive material and is inserted into the base 43 to be in contact with and electrically connected to the electrode layer 44. The fastening portion 50 in this embodiment includes a female screw 51 having a screw hole formed therein. The female screw 51 is inserted into the base 43 and connected to the electrode layer 44 of the window 43.

[ The male screw passes through the insertion hole 18 in the direction from the rear to the front of the window 40 and is fastened to the female screw 51 to fasten the window 40 and the front case 11.
An electromagnetic interference (EMI) blocking material 47 may be applied to the window seating portion 42 to electrically connect the electrode layer of the window 40 to the ground of the first body 10. [ As the EMI shielding material 47, conductive paints such as nickel, copper, silver, graphite or the like and conductive paints obtained by mixing flakes with resins such as vinyl, acrylic, polyurethane, and epoxy are used.
A metal pattern 63 functioning as a ground may be formed on the printed circuit board 60 and a rib 46 contacting the metal pattern 63 may be formed on the rear surface of the front case 11. [ An EMI shielding material 47 for dissipating static electricity from the window seating portion 42 to the rear surface of the front case 11 and the ribs 46 can be applied.
The static electricity generated from the outside or inside of the terminal bodies 10 and 20 adversely affects the electronic components mounted inside the terminal bodies 10 and 20 such as malfunction in terms of hardware and software.
The fastening part 50 relating to the present invention is for physically tightening the window 40 and the first body 10 and minimizing the influence of static electricity on the electronic parts mounted on the first body 10 .
The static electricity is passed through the internal thread 51 of the conductive material connected to the electrode layer 44 of the window 40 and finally through the EMI shielding material 47. [ And is dispersed by the metal pattern 63 of the printed circuit board 60.
The method of dissipating the static electricity to the ground is not limited to the method according to the above embodiment, but various other methods are possible. For example, by fastening the fastening screw for fastening the front case 11 of the first body 10 to the rear case 12 and the printed circuit board 60 with the printed circuit board 60, The static electricity may be dissipated.
Meanwhile, when the first body 10 and the window 40 are adhered only by an adhesive agent, when the portable terminal is left at a high temperature, the adhesive force is weakened and the window 40 tends to be lifted. The fastening portion 50 according to the present invention can minimize the lifting of the window 40. [ That is, the window 40 and the first body 10 are structurally fastened (in the form of a screw connection) to minimize the effect of the portable terminal being affected by high temperatures.
The fastening force of the first body 10 and the window 40 can be further strengthened when the adhesive and the fastening portion 50 are used together for fastening the first body 10 and the window 40 together. In addition, the contact area by the adhesive due to the strengthening of the fastening force, that is, the width of the window seating part 42 can be reduced, and the size of the screen that the user can see on the display 61 can be relatively increased.
5 and 6 are sectional views of fastening portions for explaining another embodiment of the fastening portion 50 according to the present invention and another embodiment.
5 and 6 has the same structure and function as those of the previous embodiment, except that the fastening portion 50 has the structure in the manner of fastening the window 40 and the first body 10 Otherwise.
As shown in FIG. 5, the fastening portion 50 may be formed in the shape of a hook 53. That is, the window seating portion 42 of the front case 11 is formed with a locking protrusion 48 and a side surface of the locking hook 53 is formed with a locking groove 55 corresponding to the locking protrusion 48. The hooking hook 53 is engaged with the latching jaw 48 of the window seating portion 42 so that the window 40 and the front case 11 are engaged with each other.
6, the fastening part 50 includes a holder 54 having an insertion groove 56 into which the insertion protrusion 49 formed in the window seating part 42 is inserted. The window seating portion 42 of the front case 10 is formed with an insertion projection 49 protruding toward the holder 54 so as to correspond to the position of the holder 54 on the front surface thereof. The insertion groove 56 of the holder 54 is formed in the shape of a ring whose one surface is open. When the insertion protrusion 49 is inserted into the open portion of the holder 54, the holder 54 fixes the insertion protrusion 49. In this case, it is preferable that the insertion groove 56 of the holder 54 and the insertion projection 49 are fastened in a forced fit manner.
The latching hook 53 and the holder 54 described with reference to FIGS. 5 and 6 are also electrically connected to the electrode layer 44 of the window 40 to dissipate the static electricity when the static electricity is generated. The EMI shielding material 47 may be applied to the rear surface of the front case 11 of the first body 10 and the surface of the window seating portion 42 which is in contact with the hook 53 and the holder 54. [
The fastening portions 53 and 54 according to the embodiment of Figs. 5 and 6 have a simpler structure than that of the fastening by screws, and have the advantage of achieving the same effect as a single member.
