Abstract: A fastener is made of a plastic material by integrated injection molding and has a locking portion and an installation portion, wherein the locking portion has two arm levers extended and arranged at a predetermined interval, and at least a concave buckle corresponding to another is respectively protruded from inner sides of the two arm levers. The installation portion has a cap connected to the two arm levers. A channel passing between the two arm levers is disposed to the cap, and at least an elastic hook plate is disposed at a bottom of the cap. While in use, the locking portion is stretched into the fastener insertion hole preset at the side of the notch of the board insertion slot. The elastic hook plate at the bottom of the cap is mutually buckled with the buckle hole of an inner wall of the fastener insertion hole.

Abstract: A card connector is adapted for being mounted to a circuit board defining a mounting cavity. The card connector includes an insulating housing defining a receiving room passing through a top and a front thereof, a plurality of electrical terminals disposed in the insulating housing and electrically projecting upward into the receiving room, a shielding shell enclosing the insulating housing, and a plurality of fastening blocks. A pair of side walls is formed at two opposite sides of the receiving room. The fastening blocks are apart secured to outsides of the side walls. The card connector is mounted in the mounting cavity of the circuit board, and the fastening blocks are fixed on the circuit board around the mounting cavity. Because the fastening blocks are not easily deformed, the card connector can be firmly fixed in the circuit board and avoids being slanted downward in use.

Abstract: An electrical connector adapted for electrically connecting with an electronic element includes an insulating housing and a plurality of terminals. The insulating housing defines a plurality of terminal grooves penetrating through a top face thereof. A plurality of convex blocks protrudes upward and is arranged regularly on the top face of the insulating housing. The terminals are received in the terminal grooves of the insulating housing. Each terminal has a contact portion projecting upward beyond the top face of the insulating housing from the terminal grooves for contacting with the electronic element. Tops of the contact portions are further higher than a plane determined by peaks of the convex blocks to ensure the contact portions of the terminals can be pressed down by the electronic element until the convex blocks resist against the electronic element.

Abstract: A card connector includes an insulating housing, a plurality of terminals, an ejection mechanism, a locking element and a shielding shell. The terminals are received in the insulating housing. The ejection mechanism is assembled in the insulating housing, and includes a sliding block, an elastic element and a guide pin. The sliding block includes a base block. A rear of the one side of the base block defines an inserting slot. The locking element has an inserting piece inserted into the inserting slot to make the locking element slide along with the sliding block, an elastic portion extending forward from one end of the inserting piece to be slidably disposed in the insulating housing, and a locking portion arced upward from a free end of the elastic portion to project beyond the top of the insulating housing. The shielding shell is covered on the insulating housing.

Abstract: A card connector for receiving a card includes an insulating housing having a base board and an extending portion protruded rearward from one end of a rear of the base board. One side of the base board defines a sliding recess of which a bottom wall defines a guiding slot extending along an insertion direction of the card. The sliding recess is further spread rearward into the extending portion. An ejecting device for ejecting the card out of the card connector includes a slider slidably disposed in the sliding recess. A guiding portion is protruded on a bottom of the slider and received in the guiding slot for guiding the movement of the slider. A cover has a base plate covered on the base board and an extending plate extended rearward from one end of a rear of the base plate to be covered on the extending portion.

Abstract: A connector has a top housing, a bottom housing coupled with the top housing, a plurality of terminals mounted in the top housing. The terminal has a base slice. The base slice is bent perpendicularly to form a first holding slice which has lateral sides extended outward to form a pair of fixing slices. The top housing is recessed to form a plurality of receiving passages. The receiving passage has a bottom thereof recessed to form a pair of fixing recesses. The terminal is received in the receiving passage. The fixing slices are received in the fixing recesses, which prevents the soldering slice to be knocked while assembling the bottom housing to the top housing.

Abstract: A card connector includes an insulating housing which defines a first inserting groove and two soldering openings opened behind the first inserting groove with top ends thereof communicating with the first inserting groove. A plurality of first signal terminals is disposed in the base portion and each has a contacting portion exposed in the first inserting groove and a soldering tail projecting in the soldering opening. A main shell enclosing the insulating housing has a base plate covered on the first inserting groove, and a monitoring gap opened in a rear of the base plate and facing the soldering openings. An auxiliary shell, enclosing the soldering openings after the soldering tails are soldered to a printed circuit board, has a top shielding plate mated with the monitoring gap to cover tops of the soldering openings, and a rear shielding plate covering rears of the soldering openings.

Abstract: A connector has a top housing, a plurality of terminals mounted in the top housing. The top housing forms a plurality of receiving passages therethrough. Two sides of a bottom of the receiving passage are recessed outward to form two pairs of fixing recesses. One end of the receiving passage has a top portion protruding inward to form a resting portion. The terminal has a holding slice having lateral sides extended outward to form two pairs of fixing slices. The holding slice connects with an elastic arm of substantially inverted-V shape with an opening facing to the holding slice. The holding slice is located at a bottom of the receiving passage with the fixing slice received in the holding recess for fix the terminal in the top housing. The elastic arm rests against the resting portion for preventing the deformation of the terminal by the pulling of the terminal.
