Abstract: An electronic device, which may be a USB device, includes a body part that is removably connected to a cap. The body part includes a connector for plugging the device into a host computing device. The cap includes a lever part and a main part. The lever part of the cap is attached to the main part and pivots at least partially around a pivot axis. The lever part includes an anchor part on one side of the pivot axis and an unlock part on the other side of the pivot axis. The anchor part includes a hook that engages a cavity in the body part when the cap is connected to the body part. Depressing the unlock part of the cap causes the lever to pivot around the pivot axis thereby disengaging the hook from the first cavity, and thereby releasing the cap from the body part.

Abstract: An electrical plug includes a first insulating body, a first prong extending from one end of the first insulating body, a second insulating body, and a second prong extending from one end of the second insulating body. The first insulating body and the second insulating body are separably held together so as to enable the first prong and the second prong to fit into the electrical outlets of various specifications.

Abstract: The present electrical connector assembly includes an outer shell capable of receiving at least one electrical contact module. The outer shell works in cooperation with an improved contact module retaining device which secures the electrical contact module within the shell. The combination of the outer shell with the contact module retaining device protects the critical elements of the retaining device from exterior environments, does not interfere with insertion of the module into the shell, and provides for a precise alignment of the module during and after insertion of the module into the shell. In particular, the outer shell is comprised of two half shells which are open during attachment of a contact module retaining device to each of the half shells. The two half shells are joined to form a connector housing after attachment of the module retaining device.

Abstract: A relay terminal includes a plurality of relays, a connector for entering control signals to control the relays and outputting contact inputs from their relay contacts, and a terminal block corresponding to the input and output signals of the relays, which are held as a single unit. The holding construction of the plurality of relays and the terminal block employs a two step overlapping holding construction in which the relays are held in an upper step and the terminal block is held in a lower step, resulting in a reduction in the width of the relay terminal and an increase in a package density when the relay terminal is mounted on a vertical installation wall within a control panel.

Abstract: An electrical connector is provided with a housing, female contacts, retainer clips, and contact spacers. The contact spacers surround the female contacts, have cantilevered flared legs, and have a top shelf. The legs are deflected when the spacer and female contact are inserted into the housing to form a friction grip between the spacer and the housing and, between the spacer and the female contact. The top shelf has an aperture to limit the size of male contacts to be passed therethrough and, support the bottom of the retainer clips.

Abstract: A tubular enclosure for a power connector attached to a power supply line, whereby the enclosure can be moved along the line to a position enclosing the power connector; the enclosure serves as a lock-out device to prevent the connection of the power connector to a power source by unauthorized or untrained persons. In a preferred form of the invention the enclosure is permanently retained on the power line so that it is readily available for use when needed for the lock-out function.

Abstract: The circuits contained in an electrical connection box provided near an instrument panel of a car can be separated into a plurality of separately formed connection blocks. The connection blocks each have terminals in which a plurality of conductors are press-fitted so that the connection blocks are electrically connected through the conductors and the terminals. The relative positions of the connection blocks are then adjusted so that the shapes of the connection blocks and conductors conform to the shape of the instrument panel. Thus, the connection box is close to the objects with which it is to be connected, the capacity of accommodating more fuses, circuits, etc., is increased, and electrical wires are shortened. Additionally, it is easy to adjust the connection box for various types of cars and specifications.
