Referring to
Hereinafter, although in the present example the input button 20 is a side key is, in other implementations the input button 20 may be a front key or a back key. Accordingly, it should be understood that the side key is described on the behalf of various input buttons 20.
In some aspects, when the input button 20 is a side key, the button hole 14 may be a key hole. Accordingly, it is to be understood that the terms “key hole” and “button hole” may be used interchangeably.
In some aspects, the switch 30 may include a touch panel, a pressure sensor, and/or any other suitable type of component that is capable of detecting user input. In the present example, the switch 30 is a dome type switch.
In some aspects, the housing 10 may include a wall 12 and the button hole 14 may be formed at the wall 12 and thus. Although in this example, the wall 12 is a sidewall, in other implementations the wall 12 may be, a front wall, a rear wall, and/or any other suitable type of wall.
In some aspects, a receiving slot 16 receiving the switch 30 and a pressing element 40 may be formed at the inner side of the sidewall 12, and the key hole 14 may be formed of a through hole opened from the receiving slot toward the sidewall 12. Additionally, the key hole 14 may be sized such that a fine gap is formed between the key hole 14 and the side key 20 so as to smoothly push the side key 20 while the side key 20 is inserted into the key hole 14.
The switch 30 may include a dome part 32 and an electrical terminal part 34 for delivering a signal that is generated when the dome part 32 is pressed. The electronic terminal part 34 may deliver the signal to a control unit (not shown) that is part of the electronic device. In some implementations, the dome part 32 may include domes 32A and 32B.
The side key 20 may have a protrusion part 22. The protrusion part 22 may be formed at the center of a surface facing the interior of the electronic device.
The side key 20 may be manufactured by coupling a key cap 20A with a base member, as shown in
An elastic hook 24 may be formed at each of the length direction both end parts of the side key 20. The elastic hook 24 may have a wedge shape narrowing from the key hole 14 toward the receiving slot 16.
When the side key 20 has such an elastic hook 24, it may be inserted into the key hole 14 by pressing the side key 20 against the key hole 14 in the direction from the outside of the housing 10 toward the receiving slot 16. Accordingly, the elastic hook 24 may permit the side key 20 to be easily inserted into the key hole 20. In some aspects, both ends of the pressing element 40 may be fixed in the receiving slot 16.
The pressing element 40 may have a support part 42 formed at a position corresponding to the protrusion part 22 of the side key 20 and a pressing projection 44 formed at each side.
The pressing projection 44 may have a convex shape that is oriented toward the dome part 32. On the other hand, a surface facing the side key 20 of the pressings projection 44 may have a concave shape.
Moreover, the pressing element 40 may be formed of an elastic material and it may be manufactured through injection molding. For example, the pressing element 40 may be formed of a polycarbonate material or a polycarbonate material and a urethane material. Additionally or alternatively, the pressing element 40 may be formed of a metallic material such as stainless steel (SUS), and/or any suitable type of material.
In operation, the side key 20 may perform a seesaw movement as a result of the protrusion part 22 being present. Thus, the protrusion part 22 of the side key 20 may function as a fulcrum in close contact with the support part 42 of the pressing element 40. Through this, the length direction both end parts of the side key 20 may selectively press both end parts of the pressing element 40.
With reference to
Moreover, a reinforcing rib 46 reinforcing the rigidity of the pressing projection 44 may be formed at a surface facing the sidewall 12 of the housing 10. The reinforcing rib 46 may prevent the pressing projection 44 from being damaged or its elasticity from being lowered due to repeated pressing the side key 20. The reinforcing rib 46 may be formed along a direction connecting the first end part 40A and the second end part 40B.
Although one reinforcing rib 46 is formed at each pressing projection 44 as shown in
In some aspects, a rotation center projection 48 protruding toward the sidewall 12 may be formed at the first end part 40A. In some implementations, the surface of the rotation center projection 48 may be curved.
Referring to
In some aspects, both end parts 16 of the pressing element 40 may be fixed at the receiving slot 16 (see
In some aspects, with reference to
As shown in
Moreover, the position of the first end part 40A of the pressing projection 44 is constrained between the dome part 32 and the sidewall 12. When the second end part 40B of the pressing projection 44 moves toward the left side in the receiving groove 18, with reference to
In some aspects, when the side key 20 is pressed, the part 40B may rotate and contact the sidewall 12 of the pressing element 40. Since the pressing element 40 is interposed between the side key 20 and the switch 30, when the second end part 40B is rotated, the dome part 32 may be actuated by the pressing projection 44.
In some aspects, when the key 20 is pressed, it may move along an axis A. However, when the dome part 32 is actuated as a result of the pressing of the key 20, the dome part 32 may move along the axis B. In the present example, the axes A and B are parallel to one another. In some aspects, this arrangement may drastically reduce situations in which the side key 20 is pressed several times in error or situations in which the dome part 32 is not actuated when the side key 20 is pressed.
In some implementations, when the key 20 is in a released state, the position of the first end part 40A of the pressing projection 44 may be constrained between the sidewall 12 and the dome part 32. More particularly, the second end part 40B of the pressing projection 44 may press the side key 20 outwardly (e.g., away from the housing of the electronic device) toward the outside of the housing to hold the side key 20 firmly in place and prevent it from Jittering (or rattling) while the side key 20 is in a released state.
Referring to
Moreover, referring to
Once electrical terminal part 34 is seated on the seating base 19, the first contact point 36 formed at the electrical terminal part 34 may contact a second contact point CP exposed toward the seating base 19 (see
Accordingly, when the dome part 32 is actuated, a signal may flow through the first contact point 36 formed at the electrical terminal part 34 and the second contact point CP connected to the first contact point 36. The signal may be inputted to a control unit (not shown) installed at the electronic device through a PCB P where the second contact point CP is installed.
In some aspects, the edge of the electrical terminal part 34 formed at the switch 30 may be sealed to the seating base 19 (see
