Abstract: A jig for precisely orientating a CPU over a socket of a connector comprises a frame, a limiting portion, an elastic portion and a positioning portion. The frame has an opening. The limiting portion and the elastic portion are formed on the frame. When the CPU is received in the opening, the limiting portion contacts a non-contact surface of the CPU, and the elastic portion presses the sides of the CPU. The positioning portion is formed on the frame and limits the movement of the frame relative to the socket when the CPU is received in the opening and the frame is put on the socket. Therefore, the CPU is precisely positioned over a transmission section of the socket, and a contact surface of the CPU contacts the transmission section of the socket.

Abstract: A card edge connector is provided, and comprises a first insulating housing, a second insulating housing, a pair of latches and a plurality of conductive terminals. The first insulating housing comprises a first elongated base and a pair of supporting beams. Each of the supporting beams comprises a first sliding portion. The second insulating housing comprises a pair of second sliding portions and a second elongated base with a slot and a guiding block. The second sliding portions connect with the first sliding portions. The latches are pivotally connected to the supporting beams respectively. The conductive terminals, comprising a guiding portion and a contact portion, are disposed in and through the first elongated base. When an electronic card is inserted into the slot, the relative sliding between the guiding block and the guiding portion determines if the contact portion is in contact with the electronic card inserted in the slot.

Abstract: An electric connector combination, the combination comprises an insulation main body, a first electric connector, a second electric connector, two signal displays, a rear lid and an obscuring housing; wherein the upper portion of the insulation main body can be used as a pin seat of the first electric connector, and the lower portion of the insulation main body can be used as a fixing seat of the second electric connector. In this mode, composing elements can be reduced and further lower the cost of mould making.

Abstract: The present invention relates to a memory card connector comprising an insulation base seat, a shielding shell, a plurality of conductive terminals, a detecting means, a writing-protection detecting, and a card advancing/withdrawing mechanism. The card advancing/withdrawing mechanism has an integral connecting arm, and therefore made simple constituent parts and low manufacturing cost. The present invention is applicable to memory card automatic locating and withdrawing.

Abstract: A socket has a housing for memory card such as MS card (Memory Stick Card), SD card (Secure Digital Memory Card) and MMC card (Multi Media Card), SM card (Smart Media Card). The housing is integrally formed to have a SD contact, a SD card detect contact, a SD write protect contact, a SM contact, a SM card detect contact and a SM write protect contact. Furthermore, arrangement of the different contacts enables the operator to withdraw the memory cards which are securely inserted into the socket easily to ensure the completeness and accuracy of read/write action.

Abstract: A memory module connector for horizontal insertion is disclosed. The device is formed by a long and narrow connector body, which has a horizontally directed connector slot on the lengthwise section, and the connector body has multiple terminal posts having a right-angle bent in the middle section to form an inverted “L” shape structure. One end of each terminal post is lined on the inner wall of the connector slot with a matching pair on opposing slot walls, and the other end of each terminal sticks out from the bottom of the connector body and penetrates the corresponding position on the motherboard. According to the connector design of the present invention, memory module can be inserted into the motherboard in horizontal direction, allowing for close fitting in enclosure with height or thickness limitations.

Abstract: A zero insertion force connector basing on surface contact is described, comprising a connector base having multiple connecting terminals installed thereon in array form, a sliding cover, and a clamping lever for securing the sliding cover in position. The connector is characterized in that each connecting terminal is appropriately bent at the lower end to form a contact plate, so that when the connector is placed on a substrate, each connecting terminal is matched by a corresponding solder pad leading to the internal circuit inside the substrate, and with only a small amount of applied force to join the connecting terminals onto the substrate by soldering, the connector can thus be mounted onto the substrate with reliability.

Abstract: An electrical connector for electrically connecting a CPU to a main board includes a base covered with a cover. The cover has a periphery defining an indentation therein and is formed with two pairs of tabs extending towards the base. The cover and the base are connected in a manner of allowing the cover to be movable on the base. A rotor is situated between the cover and the base near the periphery of the cover. The rotor has a middle portion and a pair of radial cams. The middle portion is provided with a slot and positioned in the indentation of the cover, and the cams have a profile designed to engage with the tabs of the cover. Therefore, the cover can be moved relative to the base when the rotor is turned by any tool extending into the slot of the middle portion.

Abstract: A connector assembly for a memory module includes a body having two standing pivot seats and two fasteners pivotally connected to the two pivot seats respectively. Each standing pivot seat has two recessed guides and two through pivot holes communicating with two recessed guides. Each fastener has a front and rear wall. Each front and rear wall has a protruding detent and a pivot pin. The protruding detents and the pivot pins correspond to the two recessed guides respectively. The pivot pins are inserted into the two through pivot holes when the fastener is mounted in the standing pivot seat so the fastener can pivot in the standing pivot seat to easily mount the memory module. In addition, the protruding detents press against the two recessed guides to hold the position of the fastener in the standing pivot seat, so the fastener can securely hold the memory module.

Abstract: A clamp assembly for an AGP display interface card includes a connector and a seat extending from one end of a socket in which an AGP display interface card is mounted. The connector is securely connected to the seat and includes a latch and a resilient look to clamp a hook on the AGP display interface card. The latch holds the hook in the connector, and the resilient loop presses against the hook to keep the hook pressed against the latch when the AGP display interface card is mounted in the socket. Therefore the AGP display interface card is stably mounted in the socket and is easily removed from the socket by releasing the connector.
