A direct-current power jack includes an insulative housing, a hole defined in a front face of the housing for insertion of a complementary power plug thereinto, a ground contact, a center contact, two switch contacts, two conductive contacts, and a joining member. When the plug is inserted into the power jack, the plug electrically connects firstly with the ground contact. The plug then electrically connects with the center contact. The plug then pushes the first switch contact to cause the first conductive contact to electrically connect with the joining member, and then pushes the second switch contact to cause the second conductive contact to electrically connect with the joining member. An electrical circuit electrically connecting with the power jack includes a ground circuit, a resistor, a capacitor and a load. The power jack prevents in-rush current sparking when it is engaged with the plug.

Anti-spark power jack

An electrical connector assembly ( ) includes an insulative housing ( ) defining a plurality of terminal receiving channels ( ) therein. A plurality of terminals ( ) is respectively secured within the terminal receiving channels of the insulative housing. A shield ( ) generally encloses the insulative housing. A locking device ( ) is formed on each of two opposite side faces of the shield, each locking device including a pair of first locking legs ( ) and a pair of second locking legs ( ). The first locking legs and the second locking legs are arranged in opposite sequence on the two opposite side faces of the shield. The first locking legs and the second locking legs each form a protrusion ( or ) projecting outwardly, each protrusion of the first legs being spaced a first distance below a lower side face of the shield and each protrusion of the second legs being spaced a second distance below the lower side face of the shield, the second distance being larger than the first distance.

Electrical connector assembly

An electrical connector assembly ( ) comprises an insulative housing ( ), a plurality of terminals ( ) within the housing and a shield ( ) covering the housing. The shield comprises a first part ( ), a second part ( ) and a third part ( ). A pair of hooks ( ) extends downwardly and forwardly from a front and lower end of the first part. A pair of ears ( ) is formed on opposite ends of a front edge of a top face of the second part and engages with the hooks. A spacing slot ( ) and a hole ( ) are defined in the housing. A pair of latches ( ) separately extend from the top and a lower face of the second part and engage respectively with the spacing slot and the hole.

Electrical connector assembly with improved shielding structure

An electrical connector includes an insulative housing, a number of contacts, a pair of fixing screws, and a first and second types of fixing devices. The housing forms a number of passageways for receiving corresponding contacts therein. The first and second types of fixing devices each comprise at least a pair of boardlocks for extending through corresponding holes in the housing and into a circuit board. Thus, the electrical connector can be securely mounted on the circuit board.

Electrical connector

An electrical connector according to the present invention comprises a dielectric housing, a plurality of terminals, a front shell and a rear shell. The dielectric housing has an upper portion, a pair of lateral faces, a central portion, and a projecting portion extending forward from a front end of the central portion. Each terminal comprises a contacting portion for being received in the projecting portion of the dielectric housing and a soldering tail for being connected to a printed circuit board. The front shell has a front wall with a front section projecting forwardly therefrom for receiving a mating plug therein. A pair of lateral walls and a pair of retention arms rearwardly extend from, respectively, side edges of the front wall and from a top edge of the front wall. The lateral walls and retention walls have latches, apertures and cutouts for engaging with the dielectric housing and the rear shell. The rear shell comprises a top wall, two side wall and a rear wall, a latching hole being defined in each side wall for interconnection with the front shell, three latching legs depending from the sides of the rear shell for securely mounting the electrical connector to a printed circuit board.
