Abstract: A cable connector for decreasing signal return loss includes a front cap, a base, and a connecting terminal. A first hole is formed on the front cap, and a second hole is formed on the base. A second front side of the base connects to a first back side of the front cap. The connecting terminal includes an elastic clamping part, a wire connection part, and a lead part. A back side of the clamping part is a free end, and a front side of the clamping part is connected to the wire connection part. The lead part is mounted in front of the wire connection part. The connecting terminal is mounted in the base, and the lead part pierces the front cap covering the connecting terminal through the first hole. The present invention prevents capacitance in the cable connector, and improves electric signal transmission efficiency.

Abstract: A cable connection element for reducing signal transmission loss includes a front clad, a base and a connection terminal. The connection terminal has a first core-holding portion formed on a front end thereof, a second core-holding portion formed on a rear end thereof, a core-clamping portion formed between the first and second core-holding portions, and a pin formed on a rear end of the second core-holding portion. The second core-holding portion is fixed inside the base. The front clad is connected with the base to enclose the first core-holding portion therein. When a core of a cable penetrates the front clad, the core is held by the core-clamping portion and is electrically connected therewith, such that signals from the core can be transmitted to the pin through the core-clamping portion and the second core-holding portion. Accordingly, signal transmission loss arising from capacitance effect can be improved.

Abstract: Radio frequency subscriber drop units include a housing having an input port and an output port and a printed circuit board mounted in an interior of the housing. The printed circuit board includes a dielectric layer, a wiring layer that includes conductive wirings that comprise at least part of a communications path between the input port and the output port that is on a first face of the dielectric layer, and a ground plane layer that includes a conductive ground plane that is on a second face of the dielectric layer.

Abstract: A signal leakage proof housing for signal distributors includes a metal case and a metal cover plate. The metal case includes a plurality of signal connection terminals and a circumferential side wall having a top surface. The top surface includes a plurality of fixing protrusions arranged at intervals on and around the top surface and at least one rib on and around the top surface. The metal cover plate includes a bottom surface which includes a plurality of fixing holes on and around the bottom surface. When the metal case and the metal cover plate are assembled together, the plurality of fixing protrusions respectively pass through the corresponding plurality of fixing holes and fix with each other and each one of the at least one rib is in direct contact with the bottom surface of the metal cover plate to achieve the objective of preventing electromagnetic signal leakage.

Abstract: Subscriber drop units include a housing having a top wall that has an exterior surface and an interior surface and a plurality of sidewalls that extend downwardly from the top wall, the top wall and the sidewalls defining an interior cavity. An input port and at least one output port extend through the housing. A printed circuit board is mounted within the interior cavity.

Abstract: A television signal splitter casing has a body and a cover. The body is hollow and has a front, an opening and a groove. The opening is defined in the front and has an annular edge. The groove is formed in the annular edge of the opening and has an inner surface and multiple saw-teeth. The saw-teeth are formed on the inner surface of the groove. The cover is mounted securely on the opening of the body and has a brim. The brim is mounted in the groove of the body. The saw-teeth of the groove tightly bite and securely hold the brim. Therefore, the cover is mounted on the body without any soldering process so that the fabricating cost of the television signal splitter casing is low.

Abstract: A waterproof splitter box includes a hollow casing with threaded sleeves integrally extending out of the hollow casing, plastic inserts each securely received in a corresponding one of the threaded sleeves, rubber plugs each having a top portion, a mediate portion and a bottom portion which is received in a corresponding one of the plastic inserts, connecting blades each extending into a corresponding one of the plastic inserts and out of the rubber plug which is received in the plastic insert and signal wires each extending and connecting to a corresponding one of the connecting blades for transmitting a signal. The engagement between the connecting blade and the rubber plug prevents moisture from entering the hollow casing so that the transmitted signal is steady.

Abstract: A signal distributor includes a main body, a screw and a clamp attached to the screw. The main body has a ground outlet formed with a threaded hole, an orifice laterally extending through the threaded hole, and a pair of grooves axially and diametrically defined in an inner periphery of the threaded hole. The screw has a head, a threaded shank engagable with the threaded hole and a flanged neck formed between the head and the threaded shank. The clamp has a strip deformable to be held in the flanged neck, two extensions extending downwardly from an under face of the strip and movable in the groove, and a contact connected to distal ends of the extensions. The contact defines a substantially V-shaped slot in an under face thereof to engage a ground wire to be held in the orifice.
