Abstract: A small form-factor pluggable (SFP) connector structure is disclosed. The SFP connector structure comprises an insulating body, a plurality of first terminals, a plurality of second terminals, and a metal cover. Two card entry slots are formed vertically on the insulating body. Dovetail structures are formed on the sides of the insulating body. The first and second terminals are disposed on the insulating body and extend into the card entry slots. The metal cover is over the insulating body. Thus, the SFP connectors can be connected in parallel without tolerance variation, hence achieving better alignment. A SFP connector assembly is also disclosed.

Abstract: The present invention provides a printed board connector reinforced with a circuit board, and the printed board connector includes an insulating casing, a plurality of signal modules, and a plurality of metal shielding elements. The insulating casing includes a rib. The rib extends a plurality of insulating shielding walls downwardly and the signal modules are received between the insulating shielding walls and are tightly mounted in the rib. The metal shielding elements are received between the insulating shielding walls and are tightly mounted in the rib and the signal modules. When a user presses the printed circuit connector to connect with a circuit board, the rib guides and positions the signal modules and the metal shielding elements, moreover, the rib enhances the strength of the assembling with the circuit board.

Abstract: A power source terminal structure includes an insertion terminal and a docking terminal. The insertion terminal has a main body and a contacting portion. The contacting portion is formed by extending from one end of the main body. The contacting portion is provided with a first protrusion. The docking terminal has a base and two elastic arms. The two elastic arms clamp the main body. The base is provided with a second protrusion opposite perpendicular to the first protrusion. The second protrusion contacts the first protrusion. Via this arrangement, the contact area between the insertion terminal and the docking terminal can be increased, and the reliability of the connector for transmitting the electric current and signals can be increased. Thus, the electric current is more stable.

Abstract: A locking handle for fixing a motherboard of a framework includes a locking part, a shell, an elastic part, and a fixing part. The locking part has an extending portion. The extending portion is projecting from the other side of the main portion. The extending portion has a stopping portion. The shell has an accommodating space inside. The shell is assembled with the extending portion slidingly. A hook and A hole are formed at a side of the shell. The hole is through the accommodating space. A grip is integrally formed at an end of the shell. The elastic part is disposed in the accommodating space. The elastic part is compressed between the fixing part and the stopping portion. The operation is easier. Moreover, the cost of manufacturing is saved.

Abstract: A connector housing for a small and portable transmitting-receiving module includes an upper housing and a lower housing. The upper housing has a top board, two side walls and a rear cover. The lower edge of the two side walls has a first wedging plate, first convex blocks, and first indentations. The lower housing has a bottom board, and the bottom board has a second wedging plate, second convex blocks, and second indentations. The second wedging plate is wedging the two side walls. The first wedging plate is wedging the bottom board. The second convex blocks are plugged into the first indentations. The first convex blocks are plugged into the second indentations. Thereby, the structure of the connector housing is stronger compared to the prior art. The housing is not easily deformed. Its structure is simple, and the manufacturing cost is reduced.

Abstract: A press-fit power connector includes a female terminal base, a plurality of female power terminals and a plurality of female signal terminals. The female power terminals and the female signal terminals are mounted on the female terminal base. Each female power terminal has a terminal contacting portion, a fixing portion, and a pin portion. The terminal contacting portion has an end hole and a clamp slot on one end, and the end hole connects with the clamp slot. The fixing portion is formed by extending the other end of the terminal contacting portion and has at least one borehole. The pin portion is formed by bending and extending one end of the fixing portion which is far away from the terminal contacting portion and has an eye of needle. Based on the above structure, the present invention can improve the yield of products and reduces manufacturing costs.

Abstract: An improved pluggable insulated terminal block includes a terminal block and a plurality of terminal-protecting pieces. The terminal block comprises a first cover, a second cover and a plurality of terminals. An inner wall of the first cover is provided with a plurality of first terminal holders. An inner wall of the second cover is provided with a plurality of second terminal holders. Each terminal penetrates through one of the first terminal holders and one of the second terminal holders. The first cover is connected with the second cover. The terminal-protecting pieces are provided between the first terminal holders and the second terminal holders. The terminal-protecting pieces are arranged on the terminals. The two ends of each terminal extend beyond the terminal-protecting piece. Via this arrangement, the terminals will not be pushed inside the terminal block, when the terminals are inserted into a circuit board.

Abstract: A locking device for a panel is provided for a single board computer for fixing onto the chassis of an industrial personal computer. The locking device includes a handle, a locking element, a first spring, a seat and a second spring. The handle has a concave groove at the front-end thereof for receiving the locking element. The first spring is placed in an inner of the locking element for abutting against an inner portion of the handle. The pin penetrates through the seat and the handle and fixes them together. The second spring is mounted on the pin and has an end hooked to the locking element. The locking element has a pressing portion. When the pressing portion is pressed, the handle and the locking element move back together through the pin as an axis.

Abstract: A protection cover integrally formed of plastic by molding ejection is provided. An elastic locking structure is disposed at two sides of the protection cover. An abutting portions having a ‘<’-shaped part and a ‘>’-shaped part is formed on the locking structure to abut against the outer edge wall of the connector so that the protection cover and the connector can be firmly connected together. Reinforcement portions are formed at the inner top face and the link positions at two inner sides of the protection cover.

Abstract: An improved connector protection cover integrally formed of plastic by molding ejection is provided. An elastic locking structure is disposed at two sides of the protection cover. An abutting portions having a ‘<’-shaped part and a ‘>’-shaped part is formed on the locking structure to abut against the outer edge wall of the connector so that the protection cover and the connector can be firmly connected together. It is not necessary to use a professional tool like a screwdriver to separate the protection cover from the connector. Scrapes on the surface of the connector can also be avoided. Moreover, reinforcement portions are formed at the inner top face and the link positions at two inner sides of the protection cover to prevent the protection cover from crushing terminals in the connector due to stacking of the connectors during transportation.

Abstract: This invention provides a combined base frame for supporting and fixing a CPU heat sink. The base frame has a left-side frame body and a right-side frame body. The buckling pieces are integrally formed under the base frame. The base frame can be efficiently mounted on a circuit board by the engagement between the left-side frame body and a right-side frame body. When an operator needs to install a CPU onto the circuit board, the base frame can be disassembled in a short time.

Abstract: A CPU cooling device with a mounting mechanism has at least one pair of wedge members. The wedge member has a positioning end for passing through a through hole of a vertical plate, a protruding block, a snapping plate for retaining a fixing frame by means of engagement of a distal snapping end on the snapping plate and a flange of the fixing frame, and an embedding plate for locking a radiator by inserting the embedding plate into a groove on a ledge of the radiator.
