Abstract: An audio jack is embedded in an open mounting slot of a printed circuit board (PCB). The open mounting slot has two opposite inside surfaces. The audio jack has an insulative housing and two sets of terminals. The total thickness of the PCB with the audio jack embedded therein is less than a sum of the thicknesses of the PCB and the audio jack so that the PCB with the audio jack may be applied conveniently to compact electronic devices.

Abstract: A coaxial connector has a hollow shell, an insulative housing, a contact terminal and a stopper. The hollow shell has at least one engaging hole. The insulative housing is mounted in the hollow shell and has at least one hook protruding through the engaging hole to securely connect the insulative housing to the hollow shell. The contact terminal is mounted in the insulative housing and has a body portion and a soldering portion extending out of the insulative housing. The stopper is mounted on the body portion and engaged with the insulative housing to avoid a disconnection between the contact terminal and the insulative housing.

Abstract: An optical fiber socket includes a hollow insulative housing, two openings in a bottom face of the insulative housing for receiving two optical fiber plugs and two illuminating elements accommodated inside the insulative housing for connection with the optical fiber plugs. The insulative housing has a first baffle and a second baffle to divide the insulative housing into a first receiving space for receiving therein one illuminating element, a second receiving space for receiving therein the other illuminating element. Terminals are provided to engage with the illuminating element in the first receiving space and have elongated ends extending out of the insulative housing thereof such that two optical fiber plugs in connection to the insulative housing are able to complete information input/output.

Abstract: An audio jack including an insulative housing, conductive terminals and a shielding shell is provided. Stripped protrusions are disposed on the two side surfaces of the insulative housing. Trenches are disposed on the two side surfaces of the insulative housing. A notch is formed on each side surface of the shielding shell, and a depressed protrusion is disposed on each side surface of the shielding shell. At least two pins are disposed on each side surface, and between the pins a U-shaped hook is formed by bending inward. A back wing is coplanar with the top surface of the shielding shell and is bent along the top surface to form a back cover. A pair of opposite side ears perpendicular to the back wing joint the depressed protrusions.

Abstract: An audio jack for a mobile communications device electrically connected with a first female connector of a charger and a second female connector of a headset thereby is provided. The audio jack includes an insulative housing, a recharging/signal transmitting unit, a first conductive terminal, and an audio terminal, wherein the recharging/signal transmitting unit includes a second conductive terminal and a central terminal. The insulative housing for accommodating all the terminals is formed with a first opening and a second opening communicated therewith for the central terminal. The recharging/signal transmitting unit and the first conductive terminal form means for recharging the charger when the first female connector of the charger is inserted into the first opening; while the recharging/transmitting unit and the audio terminal form means for transmitting audio signals for the headset when the second female connector of the headset is inserted into the first opening.

Abstract: A connector for a battery has an insulative housing and a plurality of terminals. The insulative housing has a plurality of cavities and each cavity has a front opening and two inner sidewalls. Each inner sidewall has a rear mounting slot and a front mounting slot. The terminals correspond respectively to and are mounted respectively in the cavities and each terminal has an arm portion, a body portion and a soldering portion. The arm portion is resilient. The body portion is mounted in a corresponding cavity, is formed on the arm portion and having two wing portions mounted respectively in the rear mounting slots. The soldering portion is formed on the body portion and has two hook portions mounted respectively in the front mounting slots in the corresponding cavity. The terminal is mounted stably and securely in the corresponding cavity.

Abstract: An electrical connector includes an insulated housing having a top wall formed with a top opening, a first terminal having a first solder tail projecting outwardly from the housing and a first contact part in contact with the housing, and a second terminal having a second solder tail projecting outwardly from the housing and a spring arm connected to and extending above the second solder tail. The spring arm has a second contact part disposed below and aligned with the first contact part, and a U-shaped bent portion projecting into the top opening. The second contact part is movable between a first position, in which the second contact part is urged by the spring arm to make contact with the first contact part, and a second position, in which the second contact part is moved away from the first contact part when the U-shaped bent portion is pressed downwardly.
