Abstract: A receptacle for an electrical connector includes a metal housing body, a plastic main body positioned in the metal housing body, and flat terminals. The plastic main body incorporates with the metal housing body to form an accommodating space for being plugged into by a plug. First and second tongue parts disposed on the plastic main body are respectively close to upper and lower sides of the metal housing body. Each flat terminal includes a fixing part, a contacting part formed in a flat shape, and a soldering part. The contacting parts are respectively disposed on first and second tongue parts and respectively are exposed to the accommodating space in downward and upward directions. A tongue of a plastic body of the receptacle, i.e. first and second tongue parts, and the flat terminals are thus minimally damaged, to prevent the expensive cost of repairing a damaged receptacle.

Abstract: A micro radio-frequency connector includes an isolated body, a resilient terminal and an external terminal. The isolated body includes an accommodating slot and an inserting hole connected to the accommodating slot. The accommodating slot includes an upper inner wall and a lower inner wall opposite to each other. The resilient terminal is disposed inside the accommodating slot, and includes a fixing section, two resilient arms and a first contacting section. The fixing section is fixed to the accommodating slot. An end of the resilient arm is connected to the fixing section and contacts against the lower inner wall, the other end of the resilient arm is a free end to be separated from the lower inner wall while an external force is not applied to the first contacting section and further to contact against the lower inner wall while the external force is applied to the first contacting section.

Abstract: An optical fiber connector includes a ferrule, a fastening tube, and a cover plate. The ferrule includes a through hole and a breach. Front and rear parts of the through hole respectively include a pre-embedded optical fiber and a field optical fiber. A joint of the two optical fibers is located at the breach. A part of the through hole is exposed in the breach. The fastening tube includes a ferrule accommodating portion accommodating a part of the ferrule on which the breach is disposed, and an opening disposed thereon. The opening connects the ferrule accommodating portion, and is positionally corresponding to the breach. The cover plate passes through the opening, is disposed in the breach, and presses the joint. The ferrule is easily machined and can adopt a material hardly influenced by environment temperature. The joint is fixed, and an amount of joint loss is stable.

Abstract: A switching device of electrical plug connector includes a plug body, a circuit board and a switching member. The plug body includes a connecting shell and an inserting space. The circuit board is disposed at the plug body and connected to a plurality of conductive plates. The switching member is connected to the circuit board and includes a transmission bar, a contact plate and an elastic member. The transmission bar passes through the circuit board; one end of the transmission bar is disposed in the inserting space. The contact plate is disposed adjacent to the conductive plates and connected to another end of the transmission bar. The elastic member sleeves on the transmission bar. When an electrical receptacle connector inserts into the connecting shell, one end of the transmission bar is abutted to drive another end of the transmission bar moving, thereby connecting the contact plate with the conductive plates.

Abstract: A quick lock connector assembly has a female connector and a male connector. The female connector has a first insulative housing, multiple first terminals, an outer casing and a locking lever. The locking lever is mounted pivotally on the outer casing and has two locking pins. The male connector is engaged detachably with the female connector and has a second insulative housing and multiple second terminals. The second insulative housing has two locking recesses selectively engaged respectively with the locking pins. The locking lever is able to quickly lock the male connector on the female connector.

Abstract: An electrical connector plug has resilient contact terminals for electrical connection to an electrical connector socket. The electrical connector plug has an electrically conductive housing, and a dielectric shell and resilient contact terminals are mounted in the electrically conductive housing. The dielectric shell has a base portion and a front edge portion extending from the base portion. Two groups of resilient contact terminals are mounted on the dielectric shell and axially symmetrical to each other in the longitudinal direction, with each of the resilient contact terminals having a flat section and an upwardly protruding contact section. A metallic shield frame surrounds the front edge portion and is electrically connected to the electrically conductive housing, with the metallic shield frame having a front section and two lateral protective sections. The lateral protective sections have a height no less than that of the upwardly protruding contact sections.

Abstract: A connector socket has an insulation body having thereon multiple terminals, a metal body having a receiving hole defined to receive therein the insulation body, spring clips formed on side faces thereof and having protrusions formed on the spring clips for extension and accommodation in the windows of the connector plug so as to enhance engagement with the connector plug and a protection casing for receiving therein the metal body and the insulation body to block electromagnetic interference to/from the terminals.

Abstract: A connector receptacle includes an insulation body defining a plurality of terminal slots formed thereon, multiple terminals securely received in the plurality of terminal slots of the insulation body and a metal shell which covers the insulation body and includes an upper metal shell and a lower metal shell wherein the lower metal shell is connected to the upper metal shell via a connection portion which is formed on corresponding sides of the upper metal shell and of the lower metal shell.
