  • Coaxial cable terminal
    Patent number: 7896695
    Abstract: A coaxial cable terminal includes an insulating shell and a connection terminal. An interior of the insulating shell is hollow and is thus formed with a holding space. Two ends of the insulating shell are provided respectively with an opening. The connection terminal is accommodated in the holding space and is extended toward one end to form at least two leaves. Each leaf is first bent inward with an abutting section and a tail end of the abutting section is then bent outward to extend with a contact section. A bonding end is formed between the abutting section and the contact section. When a coaxial cable terminal is inserted, the coaxial cable terminal is clamped by the bonding end and is bonded by elastic abutting of the abutting section. Therefore, the present invention can be compatible with the coaxial cables of various apertures and will not be elastically fatigue easily.

  • Gas discharge lamp
    Patent number: 7893618
    Abstract: The gas discharge lamp contains a lamp body and an UV unit. The UV unit contains a separate airtight chamber wrapping around at least a neck member of the lamp body and covering at least a part of a Mo tinsel inside the neck member. The airtight chamber is filled with one or more gases capable of being ionized, and is wound by a conductor whose one end is connected to a conduction wire extended out of one of the neck members. When the gas discharge lamp is turned on, the gases in the airtight chamber are ionized to produce an UV light to penetrate the discharge chamber. The gas discharge lamp therefore could have a lower starting voltage and an improved starting efficiency. Additionally, as the airtight chamber provides a heat insulation effect, the temperature-induced stress is thereby reduced.

  • Electrical connector for flat conductor
    Patent number: 7887351
    Abstract: An electrical connector for a flat conductor that has a novel positioning and retaining structure is disclosed. The electrical connector comprises a housing, a pressure member and a plurality of conductive terminals spaced with a certain interval and planted onto the housing. The electrical connector is characterized in a pair of prominences internally molded at two sides of a lower surface of the pressure member, and another pair of protrusions internally molded at two inner lateral walls of the housing near a front edge of the housing, namely the edge receiving the flat conductor. Thereby, when the flat conductor is inserted into the electrical connector, the flat conductor is firstly positioned by the protrusions of the housing, and then when the pressure member is closed to the housing, the flat conductor is engaged with the prominences of the pressure member.

  • Knife sharpening bar
    Patent number: 7887397
    Abstract: A knife sharpening bar includes a handle that carries a support bar. A flexible tube is tightly fit over the support bar. A hollow ceramic bar is then fit over the flexible tube with an inside surface of the ceramic bar tightly engaging the flexible tube so that the flexible tube provides a cushioning support between the support bar and the ceramic bar, which protects the ceramic bar from directly bearing any external impact applied to the knife sharpening bar. An internally-threaded cap engages an externally-threaded free end of the support bar and abuts against the ceramic bar to thereby secure the ceramic bar in position on the support bar. Collars or other buffering members can be positioned at opposite ends of the ceramic bar.
