Abstract: A communication box includes a box body and a box lid. The box body has an accommodation space therein. The box lid includes a lid body and two engaging members. Upper and lower ends of the two engaging members are detachably connected to the box body. The two engaging members are respectively and pivotally connected two opposing sides of the lid body, so that the two engaging members are rotatable relative to the lid body. Compared the conventional communication box, the communication box of the present invention can be opened in different ways. Through one of the two engaging members, either side of the box lid can be opened. Alternatively, the box lid can be detached from the box body through disengagement of the two engaging members. The present invention can be used in different occasions and is convenient for operation, without limitation of space.

Abstract: A filter adapted to DSL loop customer service end includes filter circuit, transistor control circuit, and a capacitor connected in parallel to a line, the transistor control circuit and the capacitor respectively connected to the filter circuit; the transistor control circuit is electrically connected to the capacitor; the transistor control circuit controls on and off of telecommunication signals; whereas there is no current flows through a telephone line when the telephone set is in on-hook status, the transistor control circuit is not conducted through under on-hook status so to stop the telecommunication signals from flowing through, thus to warrant that the telecommunication signals in the talking line will not shunt to a line in hook-on status for upgrading signal quality in talking mode.

Abstract: A press cord reel box is comprised of an upper casing, a press spring, a push button, a revolving cylinder, a wiring material, and a lower casing characterized in that through changed location of a pivot for the push button to press and supporting the push button by the turning axle from the lower casing, the present invention effectively prevents the push button from collapsing after longer period of repeated press; and that the purpose of product quality assurance is achieve; and that a longer service life is provided; furthermore, all structural members are reasonably disposed in the present invention to achieve simple, compact, and smaller sized assembly to provide powerful utility.

Abstract: A communication adapter for wall-mounting panel to provide better fastness, easy structure, lower production costs and powerful utility includes a casing comprised of an upper lid and a lower lid, a circuit board in the casing, plug and socket connecting to the circuit board, and locking hole on the lower lid to secure the upper lid to the lower lid with a locking pin; a locking tongue being disposed to the lower lid and a hole on the upper lid to allow pulling the locking tongue.

Abstract: A fastening mechanism formed on a rear of a box-shaped communication device includes upper and lower openings, and upper and lower latches each extended from an edge of the opening and substantially covered the opening, the latch having a hole therethrough. Inserting either bar projected from a member into the hole and lifting the communication device to flexibly deform the latches will secure the communication device to the member. There are further provided two positioning blocks formed on an inner surface of the communication device abutted two upper corners of the upper latch, another two positioning blocks formed on the inner surface of the communication device abutted two lower corners of the lower latch, and two lateral grooves formed within the communication device for permitting the positioning blocks to urge thereon.

Abstract: A universal power adapter to allow only the plug desired to stick out smoothly in a simple construction and allowing convenient operation is comprised of a lid, a base, a rotary switch, and multiple plugs; multiple channels being disposed on the external wall of the base, a standardized plug being inserted to each channel; a rotary switch containing a bar sliding block and a braking pushbutton; the bar sliding block containing a bar slide and a gap; the pushbutton being inserted into the gap; a protruding block and a slot below being disposed to the top of the plug; the slot receiving the insertion end of the braking pushbutton; and the pushbutton sliding in the channel on the external wall of the base; and the protruding block of each plug being inserted into the bar slide of the bar sliding block to slide against the protruding block.

Abstract: The present invention relates to a switcher of networks telephone and traditional telephone, which includes a sound A/D (Analog/Digital) converter with a computer connecting port that may be wire or wireless interface, said converter is connected to a switch that has a commutating circuit, and said commutating circuit connects with a speaker and a call-in alarm device, and a converter adapter, a traditional telephone port and a LAN or Ethernet port, and a handset port; by means of shifting networks telephone and traditional telephone, sharing a common microphone to send information facilitates to the consumers, meanwhile the consumers are able to handle efficiently the telephone peripheral devices, and saving consuming cost; the simplified structure and high practicality are the features of the present invention.

Abstract: The present invention provides a composite wall outlet comprised of a connector, an anchor plate and a cover plate matching on said anchor plate, wherein said anchor plate and said cover plate have a housing hole respectively for mating said connector in between said anchor plate and said cover plate, said anchor plate has location holes; the vital feature of the present invention is that the connector connects to the housing holes of the anchor plate and the cover plate in jack-socket connection, meanwhile the location holes of the anchor plate fasten the cover plate tightly for facilitating to the user mounting or dismounting, and efficiently protecting the parts from damaging; the structure of the present invention is simple and easy to operation with high practicality.

Abstract: A signal wiring elastic rewinding device comprised of a case, a reel, a spring component, a lock button, and signal wiring. The case consists of an upper case half and a lower case half that are assembled together. A plug receptacle and an opening are formed in the lateral end at the upper section and, furthermore, a containment recess is formed at the lower section of the opening and an opening is formed in another lateral end at the lower section of the case. This provides for winding the signal wiring around the reel such that after the reel is installed on a projecting shaft inside the case, the ends of signal wiring extend respectively from the two lateral openings.

Abstract: A communications cable coiling box, composed of a casing including a coiling disk, a communications cable, a flexible member, and a mechanical switch. The communications cable is folded and coiled into a lateral side of the coiling disk and an external ring and the coil disk is disposed behind an axle inside the casing, with the flexible member in the circular convex ring on the other side and coupled to the axle. The communications cable can be pulled from the openings on the lateral sides of the casing, and the flexible member and the mechanical switch control the rewinding of the coiling disk to roll up the cable. This structure allows the cable to be pulled out freely to an appropriate length for use, or attains a fast rolling of the cable by the movement of such mechanical switch and the flexible member.

Abstract: A signal adapting socket, more particularly an adapting socket for the extension of telephone lines, has an adapting socket and two guiders. The adapting socket is a rectangular plate having a plurality of grooves. Metallic wires are inlaid into the grooves connecting the ends of the adapting socket, with the metallic wires bent relative to the upper side of the adapting socket. The guiders have rectangular shapes with two bottom guiding protrusions in the interior. The two guiders are separately installed at each end of the adapting socket with the metallic wires in the spaces between each isolating bracket.
