Abstract: A wire tightening apparatus includes a housing having a ratchet gear formed in its inner periphery in a circumferential direction. A winding member is rotatably inserted into the housing, with a wire being wound therearound. A support part radially protrudes from the upper portion of a coupling shaft coupled to the housing. An intermediate member includes an engagement restriction part that is engaged with the ratchet gear and is restricted from rotating. The intermediate member has a resilient coupling hole in its center, with a resilience restriction part on the periphery thereof. The engagement restriction part is provided on an end of a blade extending from a body and having a resilient support force. The resilience restriction part is elevated by an external force coupled to the upper portion of the winding member and is supported by the outer periphery of the support part in lifted and lowered states.

Abstract: In order to significantly improve productivity and durability by simplifying a configuration, the present invention provides a wire tightening apparatus comprising: a housing having a ratchet type of gear formed in the inner periphery thereof in a circumferential direction; a winding member inserted into the housing so as to be rotatable, a wire being selectively wound therearound; a support part radially protruding from the upper portion of a coupling shaft of which the lower portion is coupled to the housing; and an intermediate member that includes an engagement restriction part selectively engaged with the ratchet type of gear and restricted from rotating in a direction, and has a resilient coupling hole formed in the center thereof, the periphery of which a resilience restriction part is formed on, wherein the engagement restriction part is provided on an end portion of a blade part extending from a body part and having a resilient support force, and the resilience restriction part is elevated by an exte

Abstract: A wire clamping device that has a simple configuration and is operated in a simple manner so as to improve convenience of use and product productivity and durability including: a housing provided with a ratchet-type gear on the inner circumference thereof and having a cylindrical inner surface; a reel axially coupled to the inside of the housing; an elevating cam having a slide protrusion-formed in the lower portion thereof, an outer circumferential cam groove formed on the outer circumference thereof, and an inner circumferential cam groove formed on the inner circumference thereof; a cam driving unit in which a cam protruding part is formed; a cam base having a guide cam and a ratchet coupling; and a rotating cover coupled to the upper part of the cam driving unit so as to be rotated in an integral manner.

Abstract: The present invention provides a wire clamping device that has a simple configuration and is operated in a simple manner so as to improve convenience of use and product productivity and durability.

Abstract: Disclosed is a handset for a communication terminal that minimizes background noise, thereby increasing the clarity of transmitted voice communication. The terminal includes a handset, an acoustic signal path on the handset, a unidirectional condenser microphone within the handset, a microphone holder to secure the microphone within the handset, and a housing to encase the microphone. The microphone is arranged to receive an acoustic signal traveling through the acoustic signal path and within the housing.
