Abstract: A power plug adapted for being assembled by a jig which defines a plurality of receiving holes therein and an engaging portion formed on each of the receiving hole, includes a main body defining a passageway and having a basic portion, a terminal received in the passageway and having a soldering piece extending out from the main body, a fixing element inserted into the passageway, a shell and a holding element. The basic portion defines a positioning portion on an outer surface thereof. The shell surrounds the main body and the basic portion extends out of the shell. The holding element has a surrounding portion clasping the shell. When the power plug is disposed in the receiving hole of the jig, the positioning portion is engaged with the engaging portion for preventing the power plug rotating in the receiving hole.

Abstract: An electrical connector adapted for being electrically connected with a PCB stably, includes an insulating housing defining a plurality of terminal passageways for receiving terminals and at least one through-hole located at one side of the terminal passageways. The insulating housing has two opposite holding blocks which defines two guiding recesses facing each other for locating the PCB. A shell encircles the insulating housing and defines at least one pressing slice passing through the through-hole and pressing against one surface of the PCB. Each of the terminals has a soldering portion exposed out of the terminal passageway and pressing against the other surface of the PCB.

Abstract: An electrical connector adapted for receiving a first electronic card and a second electronic card has a first connector element that includes a first base having a first body, and a set of first terminals received in the first base. Two lateral walls and two holding walls extending upwards and downwards from two opposite sides of the first body to form a first receiving space and a receiving chamber therebetween respectively. The first receiving space, with a first insertion opening defined, is adapted for receiving the first electronic card. A second connector element removably received in the receiving chamber includes a second base, a set of second terminals mounted in the second base and a second shell. The second shell is engaged with the second base to form a second receiving space, with a second insertion opening defined opposite to the first insertion opening, for receiving the second electronic card.

Abstract: A coaxial cable connector includes an insulating housing, a terminal received in the insulating housing and a shell surrounding the insulating housing. The insulating housing has an extending portion and an erect flat portion extending from the extending portion. The extending portion has a bottom wall and two sidewalls. The sidewalls respectively protrude toward each other to form a protruding lump. Two opposite sides of the erect flat portion respectively protrude outward to form a wedge portion. When the flat portion is bent to cover the terminal, the wedge portions are held by the protruding lumps to assure the terminal be held in the insulating housing tightly.

Abstract: A microphone connector includes an insulation housing and an electrical contact. The insulation housing has an insertion passage arranged at a top surface thereon, a receiving space arranged at a bottom surface thereon and communicated with the insertion passage and grooves passing through opposite sidewalls of the insulation housing. The electrical contact includes a body portion arranged up on the sidewalls, a soldering portion arranged at one end of the body portion, at least two opposite arms arranged at the other end of the body portion and received in the corresponding grooves respectively and elastic connection portions respectively arranged at the side arms and received in the receiving space. While a terminal of a microphone inserts into the insertion passage and electronically couples to the elastic connection portions to form multi-conductive areas, signal is transmitted between the microphone and the microphone connector stably through the multi-conductive areas.

Abstract: A coaxial connector adapted to be assembled to a coaxial cable includes a conductor shell, a dielectric housing and a connection terminal. The conductor shell has a sleeve portion. The dielectric housing has a base portion received in the sleeve portion of the conductor shell. A terminal groove is defined in the base portion. The connection terminal received in the terminal groove has a connection portion and a contact portion adapted for connecting a mating extending downward from the connection portion. A locking arm is bent upward and extending along the extending direction of the connection portion from an end thereof, a free end of the locking arm protrudes toward the connection portion to form a fixing tooth for griping an inner conductor of the coaxial cable arranged between the connection portion and the locking arm.

Abstract: A plug connector includes an insulating housing, a plurality of terminals, a rear lid and a cover. The insulating housing has a base portion and a tongue portion extending forward from the base portion and defines a plurality of receiving slots for receiving the respective terminals. Each of the terminals has a soldering section stretching out from the rear of the base portion. The rear lid has a prop section and a support section protruding rearward from the rear of the prop section. The prop section is propped against the rear of the base portion of the insulating housing and defines a plurality of channels passing therethrough. The soldering sections of the terminals pass through the corresponding channels and are supported by the support section to be soldered with cables. The cover wraps the insulating housing and the rear lid.

Abstract: A memory card connector includes an insulating housing, an auxiliary member and an ejecting device used for withdrawing a memory card from the memory card connector. The insulating housing has a base. Two sidewalls and a rear wall extend upwards from edges of the base. A plurality of terminal cavities are defined in the insulating housing for receiving a plurality of electric terminals. A cover is coupled with the insulating housing. One side of the insulating housing defines an accommodating cavity. A preventing member is formed at the inside of the accommodating cavity. The auxiliary member is received in the accommodating cavity and slides between the sidewall and the preventing member. The auxiliary member includes at least one elastic member and a cooperative member. The elastic member is located between and against the sidewall and the cooperative member. Hence, the cooperative member is blocked by the preventing member.
