A printed circuit board plug-in connection is provided for transmitting the highest possible currents between a printed circuit board and an electrical cable, the printed circuit board plug-in connection being manufactured as simply and economically as possible. For this purpose, a plug-in connection having a slotted pin contact is proposed. Said pin contact is arranged in an insulating body and can be inserted directly into a passage contact opening of a printed circuit board in order to establish electrical contact. The insulating body has detent arms, which releasably engage in detent openings of the printed circuit board in a locking manner at the same time. By means of dovetail connections, several insulating bodies can be fastened to each other, i.e., can be cascaded with each other. A strain relief element can also be fastened to an insulating body by means of the dovetail connection in order to provide strain relief for individual conductors of the cable.

A connector terminal including a cable fixing unit connected to a signal transmission cable, an upper contact-pressing unit configured to extend in one direction from the cable fixing unit, and a lower contact-pressing unit configured to extend from the cable fixing unit in parallel to the upper contact-pressing unit with a predetermined gap from the upper contact-pressing unit. At least one of the upper contact-pressing unit and the lower contact-pressing unit is provided to be elastically movable to increase or decrease the gap.

An electronic device includes a first connection module, a second connection module, and a positioning assembly. The positioning assembly includes a guide pin, a guide post, a guide bar, and an elastic component. The guide pin is fixed on a first surface of the first connection module, and the guide post is fixed on a second surface of the second module. The electronic device includes a positioning assembly which serves to position components during the installation of the electronic device. The positioning assembly provides space for positional adjustment to the first component and the second component and the elasticity of the elastic component avoids crushing or handling damage to the first component and the second component.

Disclosed is a coaxial cable male connector for transmitting super-high frequency signals, which is used in a coaxial cable connector for transmitting super-high frequency signals and is received in a connector socket mounted on a printed circuit board (PCB) to connect multiple coaxial cables to the PCB. The coaxial cable male connector includes: a single or multiple coaxial cables each including an inner conductor, an outer conductor, a dielectric, and a sheath, wherein the outer conductor, the dielectric, and the sheath are partially stripped to expose the inner conductor over a predetermined length, and a terminal of the exposed inner conductor is brought into electrical connect with a signal line terminal pad formed on the PCB; and a shielding can receiving the exposed inner conductors of the single or multiple coaxial cables, securing and protecting ends of the exposed inner conductors, and blocking electromagnetic waves generated from the inner conductors.

A connector is connected to a mating connector and includes at least one terminal, a housing and a retainer (90). The housing includes at least one fitting (72) and an exposed portion (80). The fitting (72) is fit into the mating connector and formed with a terminal accommodating portion for accommodating the terminal. The exposed portion (80) is exposed from the mating connector. The retainer (90) includes a locked portion and a locking protrusion (94). The locked portion is assembled with the exposed portion (80) and locked to a locking portion provided on the exposed portion (80), thereby fixing the retainer (90) to the housing. The locking protrusion (94) is assembled with the fitting (72) to project into the terminal accommodating portion and retains the terminal in the terminal accommodating portion.

A miniaturized card edge connector providing reliable operation. A connector may have a reinforcing member comprising a main body, a first connector engaging portion and a second connector engaging portion. The first connector engaging portion and the second connector engaging portion extend from the main body in a first vertical direction and are spaced apart in a transverse direction. The first connector engaging portion and the second connector engaging portion are configured to be engaged to both sides of a card slot of the electrical connector. The reinforcing member may effectively protect the insulating body of the electrical connector against deformation or even damage. The reinforcing member can strengthen the connection between the electrical connector and the circuit board to ensure their stable connection. Since the reinforcing member itself is multifunctional and is convenient for mounting, the assembly period may be shortened and the product cost may be lowered.

Looseness of two housings are suppressed. A connector includes a lower housing and an upper housing. The lower housing is provided with a locking portion. The upper housing is provided with an elastic locking piece that is hooked on the locking portion. The elastic locking piece has a cantilever shape, and restricts relative movement of the lower housing and the upper housing in a separation direction, which is a direction opposite to a coupling direction. The lower housing is provided with a protruding piece portion that protrude outward in a left-right direction. The upper housing is provided with a protruding piece restriction portion that restricts movement of the protruding piece portion. The protruding piece restriction portion is provided with an inclined surface that is inclined in an assembly direction to reduce a movable range of the protruding piece portion in a separation direction.
