  • Patent number: 10770823
    Abstract: A safety shield assembly for a power receptacle and a power receptacle incorporating the same. The safety shield assembly includes a frame and a sliding block and a resilient member disposed in the frame. The frame has multiple openings corresponding to multiple socket holes of the power receptacle, a position limiting member configured to abut the sliding block, and a balancing support member. In its initial state, the resilient member urges the sliding block to a closed position to covers the openings. The sliding block has two inclined surfaces. When an inserted object pushes on only one of the two inclined surfaces, the position limiting member limits the sliding motion of the sliding block; when two inserted objects simultaneously push on both inclined surfaces, the sliding block is balanced on the balancing support member and is able to slides along the frame to expose the openings.

  • Patent number: 6932631
    Abstract: A socket protective cover capable of preventing single-opening insertions includes a housing, a sliding base and covers. The housing has insertion openings. The sliding base is capable of transverse displacement in the housing, and has restoring elasticity. The covers are also provided with restoring elasticity, and have blocking members for extending into the insertion openings of the housing. When the blocking members at the covers are not simultaneously pushed and departed from the insertion openings, the other blocking member not pushed away from the insertion opening remains in the insertion opening and blocks sideward movements of the sliding base, thereby forbidding an alien object from pushing away the blocking members and thus preventing the alien object from entering the socket.

  • Patent number: 6835076
    Abstract: An electrical connector assembly is provided that includes a first connector having a slidable cover and alignment post receiving sockets, a second connector constructed with alignment posts, and a flexible mounting bracket. The cover protects terminals mounted in the first connector from dirt and debris when the connector is in an unmated state. As the second connector is engaged with the first connector, angled surfaces on the alignment posts of the second connector cooperate with chamfered surfaces on the first connector to guide a misaligned second connector into the first connector. Angled surfaces on the alignment posts and cover cooperate to move the cover exposing the terminals on the first connector for electrical connection with terminals on the second connector.

  • Patent number: 6814594
    Abstract: The invention discloses a composite elastic member of socket protective safety cover, in that the composite elastic member is disposed in a socket safety protective cover, is capable of providing the protective cover with vertical restoring elasticity and horizontal elasticity, and forms fulcrums for swinging movements of the protective cover. The composite elastic member includes vertical elastic plates, a horizontal elastic plate and a fixing section. A highest point of each vertical elastic plate forms a support point. The horizontal elastic plate is located at a side of the vertical elastic plates, and has action directions perpendicular to those of the vertical elastic plates. The fixing section is located out of action ranges of the vertical elastic plates and the horizontal elastic plate, and is for fixing an entire structure to an external object.

  • Patent number: 6776630
    Abstract: A safety socket protective cover includes an outer housing, an inner housing, a sliding cover, an elastic support member and an elastic member. The sliding cover, the elastic support member and the elastic member are disposed at a gap between the outer housing and the inner housing. The sliding cover is provided with wedge members for corresponding with receptacles at the outer housing, wherein each wedge member has a passive inclined plane. The elastic support member has elastic restoring forces and is disposed below the sliding cover. The elastic member is pressed between the sliding cover and the outer housing. When the sliding cover receives abnormal forces, the wedge members block the receptacles at the outer housing due to unequal forces received, thereby preventing alien objects from entering the receptacles.

  • Publication number: 20030157820
    Abstract: A connector has a housing (10) with cavities (11) and a lock (17) in each cavity (11) for locking a terminal fitting (40). Each lock (17) has thin portions (17B) formed by partially cutting a surface thereof facing a deformation permitting space and a thick portion (17A) thicker than the thinner portions (17B). Deformation-preventing portions (32) are insertable into recesses formed by a difference in the thickness between the thick and thin portions (17A, 17B) to restrict resilient deformation of the locks (17). The connector can be made smaller because the locks (17) and the deformation-preventing portions (32) overlap along the thickness direction.

  • Patent number: 6547444
    Abstract: The invention is directed to techniques for controlling access to an optical interface using film having windowed sections and non-windowed sections. The windowed and non-windowed sections are selectively positioned over an optical interface location that holds the optical interface in order to protect the optical interface. Preferably, such positioning occurs in an automated manner such that a technician need not perform an extensive cleaning step each time fiber optic equipment requires handling, e.g., each time a fiber optic connector of a fiber optic component is unplugged and re-plugged. In one arrangement, an optical connector housing holds the optical interface in an optical interface location of the optical connector housing, and a film positioning assembly selectively positions windowed and non-windowed sections of film over the optical interface location in order to selectively expose and protect the optical interface.

  • Patent number: 6537089
    Abstract: An electrical outlet, used with a plug having live and neutral prongs of equal length, comprises support member having live and neutral apertures, and live and neutral receptacles for receiving the prongs. A blocking member lies between the support member and the receptacles, and moves between a closed position, in which it blocks the apertures, and an open position, it which it does not block these apertures, thus permitting the prongs to enter the receptacles. The blocking member is biased towards its closed position, but has a cam surface which contacts the entering neutral prong and moves the blocking member to its open position. The blocking member also has a recess so that, when the blocking member is in its closed position, a portion of the live prong can lie within the recess.
