Abstract: A connector insulator for a female connector includes a plurality of U-shaped grounding terminal openings and signal terminal openings surrounded by the grounding terminal openings. A plurality of terminal modules corresponding to the grounding terminal openings and the signal terminal openings are fitted into a side of the connector insulator. Signal terminals and U-shaped grounding terminals of a male connector are fitted into the signal terminal openings and the grounding terminal openings to be electrically connected with signal pins and grounding pins of the terminal modules, respectively. Because the U-shaped grounding terminals surround the signal terminals so the connector insulator having the U-shaped grounding terminal openings provides an improved EMI shielding.

Abstract: A grounding terminal for electrical connector, which can reduce noise, includes a main body, a wing portion and a coupling portion. A connector insulator includes signal terminal openings and L-shaped or U-shaped grounding terminal openings. The wing portion and the coupling portion are extended from both lower side edges of the main body, respectively. Thus, the grounding terminal can be engaged with the L-shaped or U-shaped grounding terminal opening. Although the grounding terminal is not in U shape, the grounding terminal and the grounding terminal opening surround the signal terminals. Therefore, the grounding terminal still provides an EMI shielding similar to that of a conventional U-shaped grounding terminal.

Abstract: A terminal module for a female connector has a metal grounding member and an insulating terminal base to receive the grounding member. The grounding member includes an extension portion and a contact arm corresponding to the extension portion. The extension portion is extended from an edge of the grounding member and parallel to the edge of the grounding member. The contact arm is extended from a side surface of the grounding member and away from the extension portion. When a plurality of the terminals modules is fitted into a connector insulator of the female connector, the extension portions and the contact arms of the terminal modules are contacted with each other and are electrically connected in series.

Abstract: A female connector that is easy to be engaged with a male connector includes a connector insulator and a plurality of terminal modules inserted into the connector insulator. The terminal module includes grounding pins and fork-shaped signal pins. The signal pin has twisted pin arms and a raised arm portion. The connector insulator includes grounding terminal openings and signal terminal openings. The signal terminal opening includes a raised opening bottom, which has a slope portion and a raised portion. The twisted pin arms provide smooth surfaces to allow a signal terminal of a male connector being smoothly inserted between the pin arms. The raised arm portion, the slope portion and the raised portion allow the two pin arms keeping a distance away from each other.

Abstract: A circuit board type connector includes a connector socket and a connector plug. In the connector plug, a circuit board replaces wires or cables to transmit signals. The connector is provided with a clipping device to clip the circuit board and securely connect the connector plug with the connector socket. The clipping device includes a pair of clips, a supporting plate and a circuit board cover to securely hold the circuit board. The clip engages with a clip connection slot of the connector socket to securely connect the connector plug with the connector socket.

Abstract: A connector with a locking mechanism includes an insulating body, a plurality of terminals, a metallic casing and a pair of locking pieces. Both sides of the insulating body are provided with two accommodating troughs. The insulating body is provided with pivot shafts in the two accommodating troughs respectively. The terminals are provided in the insulating body. The metallic casing is provided on the insulating body. The two locking pieces are provided in the two accommodating troughs respectively. Each locking piece is provided with a pivot hole, and the pivot hole is fitted with the pivot shaft of the insulating body. The locking piece is formed with an elastic arm by extending from a wall surface of the pivot hole. The elastic arm abuts against the pivot shaft. Via this arrangement, the locking piece is simple in structure, and can be manufactured easily, thereby reducing production costs.

Abstract: A connector is assembled by providing a base and an earth terminal unit which is located to be aligned with the base and the earth terminal unit is pressed into the base to let a front end of the earth terminal unit contact an inside of the base. A casing is then provided to be in alignment with the base and then press the casing into the base. A signal terminal unit is then provided which is in alignment with the base. The signal terminal unit is then pressed into the base and a front end of the signal terminal unit contacts the inside of the base. By the method, the signal terminal unit is securely connected to the base.

Abstract: A connector includes a passage defined in a rear end thereof and a cover is pivotably connected to the connector. The cover includes a plurality of engaging teeth defined in an underside thereof and an axle passing through the engaging teeth. A terminal has a base from which a contact arm and a connection arm extend. The contact arm has a terminal contact end at a distal end thereof and the connection arm has a connection portion projecting from a distal end thereof. A notch is defined in the connection portion. A sharp plate extends from a top side of the connection arm. The terminal extends through the passage of the connector and the axle of the cover is engaged with the notch of the connection arm and the sharp plate is securely in contact with the inside of the passage of the connector.
