  • Publication number: 20250027597
    Abstract: The present application provides a height-adjustable mount, comprising a first frame assembly, a second frame assembly, a rotation assembly, and a balance assembly. The first frame assembly includes a first frame and a middle connecting plate connected to the first frame. The first frame assembly is slidably disposed relative to the second frame assembly. Two rotation assemblies are symmetrically disposed along the first direction, and each rotation assembly includes a first rotating member and a second rotating member. The balance assembly includes two elastic arrangements symmetrically disposed along the first direction. Wherein the rotation assemblies enable the first frame to move up and down relative to the second frame and stop at any position under the action of an external force, and the elastic force generated by the elastic arrangement, the first elastic member and the second elastic member is used to counteract the gravity of the load of the first frame.

  • Patent number: 7090535
    Abstract: An electrical connector (100) mounted on a mother printed circuit board includes an insulative housing (1) defining a plug-receiving cavity (10), a conductive outer shield (2) enclosing the insulative housing, a terminal module (3) and a daughter circuit board (4) assembled into the plug-receiving cavity of the housing, and a connecting module (6) electrically connecting with the daughter circuit board. The connecting module includes a pair of first connecting contacts (61) for contacting with the daughter circuit board, a pair of second connecting contacts (62) for contacting with the mother printed circuit board and mode choke coils (65) for connecting with the first and the second connecting contacts. The electrical connector further includes a dielectric block (7) positioned between the second connecting contacts and the daughter circuit board.

  • Patent number: 6935900
    Abstract: A modular jack (100) includes an insulative housing (2) with a plug-receiving cavity (24), an anti-mismating member (3) and a terminal module (4) received in the housing, and a metal shell (6) shielding the housing. The anti-mismating member (3) is formed by one metal sheet and includes a pair of cantilevered branch portions (32) extending forwardly into the plug-receiving cavity. Each branch portion includes a stopping tab (33) projecting upright from an inner side thereof and a guiding portion (34) extending upwardly from an outer side thereof. Each stopping tab has an engaging surface (331) facing forwardly. Each guiding portion has an inclined guiding surface (341) in front of the engaging surface.

  • Patent number: 6918794
    Abstract: A modular jack (100) includes an insulative housing (1) having a plug-receiving cavity (10), a number of conductive terminals (322) and an anti-mismating member (2) received in the housing (1) and a metal shell (4) shielding the housing (1). The anti-mismating member (2) includes a metal main portion (21) having a horizontal spring arm (212) and an insulative portion (22). The insulative portion (22) is located at a free end of the spring arm (212) and includes a sliding surface (222) and a stop surface (221) attached to an inner side of the sliding surface (222) at a free end thereof. When an undersized plug is inserted into the cavity (10), the leading edge of the undersized plug contacts the stop surface (222), preventing full insertion of the undersized plug into the cavity (10). When a mating plug is inserted into the cavity (10), the leading edge of the mating plug contacts the more forwardly-positioned sliding surface (222) before reaching the stop surface (221).

  • Publication number: 20050101189
    Abstract: An electrical connector (100) mounted on a main printed circuit board includes a dielectric housing (1) defining a receiving cavity (10) and an insert module (2) received in the housing. The insert module includes an insulative base (21) defining a groove (20), an internal circuit board (220) fixed in the groove and a number of conductive terminals (23) mounted on the base. Each terminal includes a body portion (230) fixed in the base, a contacting portion (231) extending upwardly and rearwardly from the body portion and exposed in the receiving cavity, and a mounting portion (232) extending rearwardly from the body portion for mounting on the internal circuit board.
