Abstract: The invention relates to a fastener. The fastener includes: a lower fastening base, in which a pivoting plate is disposed upward on a back end of the lower fastening base and concavely disposed with a limiting groove, an upper fastening plate, disposed on the lower fastening base in a covering manner, in which a back end of the upper fastening plate has at least one pivoting portion pivotally connected to the pivoting plate, a limiting portion, extending backward from the upper fastening plate and penetrating the limiting groove correspondingly, at least one stop block, convexly extending from the limiting portion and located behind the pivoting plate, and a fixing part, disposed on a frond end of the lower fastening base and used for fixing the upper fastening plate to the lower fastening base.

Abstract: An electrical connector includes a body having a plurality of receiving slots, a plurality of terminals respectively accommodated in the receiving slots, each terminal having a stopping portion, and a cover, slideably covered on the body, and having a plurality of pressed surfaces respectively corresponding to the stopping portions. When the cover slides along a first direction relative to the body, the stopping portion limits upward displacement of the pressed surface, so as to limit upward warping of the cover, thereby ensuring good contact between the terminal and a mating element.

Abstract: An electrical connector is used for electrically connecting a chip module and includes: an insulating body, having a plurality of receiving slots; and a plurality of terminals, disposed in the receiving slots and each having a base plate, a contact arm and at least one extending arm, in which the base plate is fixed in the receiving slot, the contact arm is located on one side of the base plate and has a contact portion conducting the chip module, the contact portion is higher than the base plate and is exposed outside the receiving slot, and the extending arm is in a bent shape and has a lower end connected to the contact arm and an upper end connected to the base plate.

Abstract: An electrical connector with a plurality of solder balls arranged therein. In one embodiment, the electrical connector includes: an insulating body, wherein a plurality of receiving slots are formed through the insulating body, and at least one side surface of each receiving slot forms a stop wall; and a plurality of conductive terminals, received in the receiving slots. Each conductive terminal has a base, at least one fixing portion extends downwards from the base, and a soldering portion is bent laterally and extends from the fixing portion. The soldering portion includes a soldering arm and a hook portion bent and extending from a lower end of the soldering arm towards the stop wall. The solder ball is clamped between the soldering portion and the stop wall. The hook portion has at least one retaining point urging against a lower hemispherical surface of the solder ball.

Abstract: A shielded connector. In one embodiment, the shielded connector includes: a seat, including an insulating body with a plurality of through slots and a plurality of positioning slots, in which a shielding body is disposed in the through slot and no shielding body is disposed in the positioning slot, at least one conductive body connected to the shielding bodies, and at least one lead-out portion electrically connecting the conductive body to a motherboard; and a plurality of conductive terminals, each including a contact portion, a body portion extending from the contact portion, and a connecting portion, in which the body portion includes a positioning section extending from the contact portion and in interference fit with the positioning slot, and a conducting section extending from the positioning section into the through slot and not in interference fit with the through slot.

Abstract: This invention relates to a “bicycle structure with concealable brake”, comprising a brake and a frame. The frame is a front fork having a positioning hole positioned on the joint of two fork portions for the brake to be pivotally disposed therein. In addition, the positions near the upper ends of the two fork portions on the front fork of said bicycle set two containing holes for respectively containing two brake pads of the brake; moreover, the activation of a brake cable of the brake enables the two brake pads to respectively extend out of the containing holes and clip a bicycle rim.
