Abstract
An electronic device and a key coupling unit therefor are disclosed. The key coupling unit includes a key configured in a specific shape, a key guide frame configured to guide pressing of the key, and a key circuit board configured to input a signal corresponding to the pressing of the key. The key coupling unit is fixed in a settling area of a bracket. A bumper is formed to protrude from the lower part of the key circuit board. A pressing part is formed in the bracket to face the bumper of the key circuit board. A command signal of a corresponding key is transmitted to the key circuit board by converting to an electric signal if the bumper presses the pressing part. The bumper and the pressing part are located by moving in a lateral direction from the center of the settling area of the bracket.
Claims16
A key coupling unit for an electronic device, the key coupling unit comprising:
- a key configured in a specific shape;
- a key guide frame configured to guide pressing of the key;
- and
- a key circuit board configured to input a signal corresponding to the pressing of the key,
- wherein the key coupling unit is fixed in a settling area of a bracket, the settling area is formed by recessing the bracket along a pressing direction of the key, a bumper is formed to protrude from a lower part of the key circuit board, a pressing part is formed in the bracket to face the bumper, a command signal of a corresponding key is transmitted to the key circuit board by converting to an electric signal if the bumper presses the pressing part, and the bumper and the pressing part are laterally offset from a center of the settling area of the bracket,
- wherein the key guide frame further comprises a pair of support frames, each of which protrudes from a respective end of the key guide frame, and
- wherein a first distance from a center of the bumper to an end of one of the support frames and a second distance from the center of the bumper to another end of the key guide frame have a difference as much as an extruded length of the support frames.
An electronic device comprising:
- a key coupling unit including a key configured in a specific shape, a key guide frame configured to guide pressing of the key, and a key circuit board configured to input a signal corresponding to the pressing of the key;
- a bracket having a settling area for fixing the key coupling unit;
- and
- a window configured to support the key guide frame of the key coupling unit and to expose the key guide frame through an opening,
- wherein the settling area is formed by recessing the bracket along a pressing direction of the key,
- wherein a bumper is formed to protrude from a lower part of the key circuit board, a pressing part is formed in the bracket to face the bumper, a command signal of a corresponding key is transmitted to the key circuit board by converting to an electric signal if the bumper presses the pressing part, and the bumper and the pressing part are laterally offset from a center of the settling area of the bracket,
- wherein the key guide frame further comprises a pair of support frames, each of which protrudes from a respective end of the key guide frame, and
- wherein a first distance from a center of the bumper to an end of one of the support frames and a second distance from the center of the bumper to another end of the key guide frame have a difference as much as an extruded length of the support frame.
