Abstract: An electrical connector assembly includes a plug having a first mating portion defined by a multi-sided first confining wall, and a receptacle having a second mating portion defined by a multi-sided second confining wall. Each of the first and second confining walls has opposite first and second sides, a pair of opposite third sides respectively connected to two opposite ends of the first side, a pair of fourth sides respectively connected to two opposite ends of the second sides, and a pair of fifth sides each extending between and interconnecting one of the third sides and one of the fourth sides. The first side is longer than the second side. The width between the third sides is greater than that between the fourth sides. The fifth sides are angled away from each other while extending from the fourth sides to the third sides.

Abstract: An electrical connector includes an insulator housing that has a base portion, a mating portion, and two retaining extensions. A plurality of terminals extend in the mating portion. Each retaining extension includes a lower part formed with a retaining slot, a top retaining wall defining a top end of the retaining slot, and a bottom opening. A pair of board locking members have inserting portions disposed in the retaining slots, and locking pegs projecting downwardly from the inserting portions through the bottom openings. The inserting portions abut against the top retaining walls when the locking pegs are pushed upwardly by an external force.

Abstract: An electrical connector includes a first terminal module having a row of first terminals and an insulative first seat body molded over the first terminals, a second terminal module having a row of second terminals and an insulative second seat body molded over the second terminals, a coupling member disposed on and coupling the first and second seat bodies, an insulative housing having a sleeve portion receiving the first and second terminal modules, a retaining member disposed on the housing for positioning the first and second seat bodies to the housing, and a metal shield surrounding the sleeve portion.

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.

Abstract: A USB electrical connector includes an insulative seat body having a top wall and a protrusion projecting from the top wall, a plurality of terminals mounted on the seat body, and a metal shell snugly receiving the seat body and having a front open end, a top wall which has an opening interlocking with the protrusion, a slit that extends from the front open end to the opening, and two opposite resilient anchor plate portions that extend between the front open end and the opening on two opposite sides of the slit.

Abstract: An electrical connector is adapted for electrical connection with a plurality of electrical cables. The electrical connector includes a terminal seat, a positioning seat, and a plurality of clamping elements. The terminal seat includes an insulating body that is made of an insulating material, and a plurality of parallel terminals pins that are secured to the insulating body. Each of the terminal pins has front and rear ends that project respectively from front and rear side surfaces of the terminal seat. The positioning seat is located behind the terminal seat, and is made of an insulating material. A plurality of accommodating holes are formed through the positioning seat. The clamping elements are made of a conductive material, and are confined respectively within the accommodating holes in the positioning seat.

Abstract: An electrical connector includes a terminal holding frame, first and second sets of conductive terminals mounted respectively on upper and lower terminal holding plates of the terminal holding frame in a superposed relationship, and a first metal shield that encloses the terminal holding frame. The metal shield has a closed rear side to enhance electromagnetic shielding of the conductive terminals. In addition, a second metal shield encloses a partition plate between the upper and lower terminal holding plates of the terminal holding frame. The second metal shield is formed with a pair of resilient grounding strips disposed forwardly of the partition plate. When the electrical connector is installed in a housing of an electronic appliance, the resilient grounding strips abut against the housing for grounding purposes.

Abstract: A shielded receptacle connector includes a dielectric terminal mounting seat having a terminal aligning portion for mounting solder tail portions of a plurality of contact terminals and a mating portion for mounting contact portions of the contact terminals. The terminal aligning portion has a proximate end face and a distal end face relative to the mating portion, a pair of lateral walls extending between the proximate and distal end faces and opposite to each other in a transverse direction, and a pair of tongue engaging groove units formed in the lateral walls respectively and extending from the proximate end face towards the distal end face and crossing over at least one of the solder tail portions.

Abstract: An electrical connector includes a dielectric terminal mounting seat, a contact terminal set mounted in the terminal mounting seat, a metal shield enclosing the terminal mounting seat, and a dielectric casing enclosing the metal shield. The terminal mounting seat includes a base member and a cover member. The base member includes a bottom wall with front and rear portions. The contact terminal set is mounted on the bottom wall, and extends from the front portion to the rear portion. The base member further has a top side formed with an opening. The cover member is mounted movably on the base member so as to close the opening and so as to clamp the contact terminal set against the base member.

Abstract: An electrical connector is adapted for mounting on a printed circuit board having mounting holes with corresponding solder pads on a surface of the printed circuit board. The electrical connector includes a dielectric body and two conductive members mounted on the dielectric body. The dielectric body has top and bottom faces, two receiving holes extending from the top face to the bottom face, and two hollow protrusions formed respectively on the bottom face of the dielectric body in communication with the receiving holes and adapted to extend respectively into the mounting holes of the printed circuit board for preventing solder material from wicking into the receiving holes.
