Abstract:
A wireless transmission system used for a self-locking lock box has a first transmission unit received in a first insert hole of a door frame, and a self-locking lock box secured at a door plank. The self-locking lock box is provided therein with a square bolt able to eject out of the lock box, and the square bolt is connected with a control pin and has its front end fixed with a second transmission unit. By so designing, when a user closes the door plank, the control pin will be pressed by the door frame and release the square bolt to make the square bolt eject out of the self-locking lock box and get into the first insert hole of the door frame, thus enabling the first transmission unit to approach the second transmission unit for elevating transmission efficiency.
Abstract:
A board-to-board connector assembly includes a receptacle connector and a plug connector. The receptacle connector has a receptacle housing, a plurality of first terminals disposed in the receptacle housing, and at least one first fixing member mounted to the receptacle housing. The first fixing member has a first base portion, an elastic portion bending toward one side and then extending downward from a top of the first base portion. An outside portion of the elastic portion defines a fixing cavity opposite to the first base portion. The plug connector has a plug housing mated with the receptacle housing, a plurality of second terminals disposed in the plug housing and contacting the corresponding first terminals, and at least one second fixing member mounted in the plug housing and defining at least one fixing portion which is buckled into the fixing cavity of the corresponding first fixing member.
Abstract:
An audio jack connector for receiving a mating audio plug has an insulating housing having a rectangular base. The base defines a front end and a top surface. A passageway is formed at the front end of the base and extends into the base for receiving the audio plug. The top surface of the base has a receiving recess adjacent to the front end. A plurality of terminals is received in the insulating housing and projects into the passageway. A protecting plate is swingably mounted in the receiving recess of the insulating housing. The protecting plate has a base plate, with a shape substantially same as a cross-section of the passageway. The base plate stands across a front end of the passageway for shutting the passageway, and is pushed by the inserted audio plug to swing upwards and received in the receiving recess. A shielding shell covers the insulating housing.
Abstract:
A fluorescent tube has a seat, a circuit board, multiple light-emitting-diodes (LED), a lampshade and two electrical terminal. The seat has two ends and a mounting surface. The circuit board is mounted on the mounting surface and has top surface. The LED is mounted on the top surface of the circuit board. The lampshade is transparent and is mounted on the seat, covers the circuit board and has an inner surface and a lens. The inner surface is opposite to the mounting surface of the seat. The lens is formed on the inner surface and faces the LEDs to guide the light of the LEDs. The electrical terminals are respectively mounted on the ends of the seat. Because the fluorescent tube does not have any reflection board, the manufacturing time and cost of the fluorescent tube decrease.
Abstract:
A board-to-board connector adapted for being soldered to a printed circuit board includes an insulating housing, two soldering members and a plurality of electrical terminals. The insulating housing has a base board and four sidewalls extending downward from the base board. Two ends of a top of the base board respectively define two fixing slots spaced away from each other. Each of the soldering members has a soldering plate disposed on the top of the base board for being soldered to the printed circuit board. Two opposite ends of the soldering plate bend downward and then extend to form a pair of fixing portions respectively fastened in the corresponding fixing slots. The electrical terminals are disposed in the insulating housing and located between the two soldering members for being soldered to the printed circuit board.
Abstract:
A board-to-board connector includes a socket and a plug. The socket has a dielectric housing and a plurality of receiving terminals received in the dielectric housing. The dielectric housing defines a recess and a plurality of sidewalls surrounding the recess. At least one of the sidewalls defines at least one fixing groove connecting to the recess and passing through a top portion of the sidewall. A central portion of two opposing sides of the fixing groove protrudes towards each other to form two facing fixing projections to make the central portion of the fixing groove narrower than two ends thereof. The plug engages into the recess of the socket. The plug has a dielectric body and a plurality of inserting terminals received in the dielectric body. The dielectric body protrudes sideward to form at least one locating lump corresponding to the fixing groove. The locating lump passes from between the two fixing projections by extrusion therebetween and then is blocked by the two fixing projections.
Abstract:
A card connector includes an insulating housing and an upper cover coupling with the insulating housing. The insulating housing includes a bottom wall, two sidewalls and a back wall, all the walls forming a receiving space therebetween to receive one of a variety of memory cards. One side of the receiving space defines a sliding groove and the other side defines a terminal cavity. Contacts which are divided into two groups are received in the insulating housing respectively. An ejecting apparatus is arranged in the sliding groove. An elastic terminal, located in the terminal cavity, has a base portion. An elastic arm connects with the base portion and continuously protrudes toward the inside bottom wall to form a contacting portion.
Abstract:
A battery connector with retaining board includes an insulating housing and a plurality of terminals received in the insulating housing. Each terminal includes a connecting portion, a contacting portion and a soldering portion. The insulating housing has a vertical cooperating wall. A top wall and a retaining board backward extend from the backside of the vertical cooperating wall, thereby a retaining space is formed therebetween. The backside of the cooperating wall defines a contacting side formed between the top wall and the retaining board. A printed circuit board is retained in the retaining space and one end of the printed circuit board is depressed against the contacting side of the insulating housing whereby a firmly engagement is between the printed circuit board and the battery connector. Therefore, an electrical connection therebetween is stable.
