A keystone jack assembly includes a jack housing, a piercing contact housing disposed on the jack housing, a plurality of piercing contacts mounted on the piercing contact housing, a wire cap movably disposed on the piercing contact housing and a cover pivotally connected to the jack housing. The wire cap includes a cap main body, at least one first guiding portion, at least one second guiding portion and a third guiding portion. The cover includes two covering parts, and each covering part includes a main body, at least one first contact portion, at least one second contact portion and a third contact portion. The first contact portion abuts against the first guiding portion, the second contact portion abuts against the second guiding portion and the third contact portion abuts against the third guiding portion in order as the two covering parts pivots toward each other.

An electrical connector includes an insulative housing, a plurality of slit type passageways, a plurality of blade type contacts retained with the corresponding slit type passageways, respectively, and a plurality of wires having the inner conductors soldered upon the tails of the contacts behind the rear face of the housing. The rear face forms a plurality of standoffs on which the front ends of the exposed inner conductor abut, respectively. A waterproof glue plate fills the back space of the housing behind the rear face to enclose the exposed inner conductors and the corresponding tails and seal the rear face of the housing.

A connector body includes a mating guide part having a mating recess, a reinforcing bracket includes a body part attached to the outer side of an end wall part of the mating guide part, an end wall cover part connected to an upper end of the body part and covers an upper side and an inner side of the end wall part, and a contact arm connected to a lower end of the end wall cover part, the contact arm includes a bottom surface part extending along a bottom surface of the mating recess and an upright part extending upward from a tip of the bottom surface part, and the upright part includes a contact projection near a tip thereof, the contact projection extending toward the center in the width direction of the connector body.

A connector includes: half body parts each including a connector body, and a plurality of terminals attached to the body; end parts formed on both ends of the body formed by allowing the bodies to abut each other; and reinforcing brackets attached to the respective end parts. Each of the bodies is a member integrated with the terminals by primary insert molding, and includes a protrusion extending in the longitudinal direction and holding the terminals, and an embedded part connected to both ends in the longitudinal direction of the protrusion. The end part includes a covering part covering at least the embedded part of each of the bodies, and the covering part is a member integrated with the embedded part and the bracket by secondary insert molding. The connector allows for the spacing between protrusions to be narrowed, simplifying manufacturing, reducing size, and improving reliability.

A connector including a female connector and a male connector is provided. The female connector has a female terminal, a female terminal accommodation portion, and a female-side finger-touch prevention portion. The female-side finger-touch prevention portion is arranged in an entrance of the female terminal accommodation portion, and is configured to generate a force for biasing toward a center of the opening in a state where the opening is enlarged in diameter with insertion of the male terminal. The male connector has a male terminal including a recess in an intermediate portion of an electrical contact portion. The recess of the male terminal is formed in a portion where the opening of the female-side finger-touch prevention portion can be fitted into the recess at a position before the male terminal contacts the female terminal and where the opening can be remove from the recess at a position after the male terminal contacts the female terminal.

In a low-height connector combination, a duplex electrical connection socket includes: an insulation base having a tongue, and a metal housing formed with a connection slot. Heights of spaces of the connection surfaces are smaller than a large space of a standard socket having a minimum height and greater than a small space of the standard socket. A duplex electrical connection plug includes an insulation base, a metal housing and a fitting portion having two contact interface substrates and a fitting space. Heights of the contact interface substrates are smaller than a contact interface substrate of a standard plug having a minimum height and greater than the small space. The fitting portion can be bidirectionally inserted into the connection slot. Each of two fitting gaps of the fitting portion between the contact interface substrates and the connection surfaces of the tongue is smaller than 0.15 mm to form tight fitting.

The present invention provides for an analog audio patchbay comprising a first plurality of connectors capable of receiving a plurality analog electronic signals, a second plurality of connectors capable of transmitting a plurality of analog electronic signals, and a circuit board extending from the first plurality to the second plurality

An electrical outlet has a female member with at least two electrically conductive contact sleeves for the reception of the pins on a plug inserted in the female member and a connecting means for connection of the electrical outlet to a mains supply. The female member is movable relative to the connecting means between a first mode, in which the contact sleeves are electrically disconnected from the mains supply, and a second mode, in which contact sleeves are electrically connected to a mains supply. The connecting means include a connection ring and a mounting plate. The connecting means further include connection plates, whose number corresponds to the number of contact sleeves on the female member, wherein each contact sleeve is brought in or out of contact with a connection plate by movement of the female member.
