A board end connector and a connector assembly. The board end connector comprises a board end insulating body, a terminal module, and a housing. The board end insulating body comprises a board end plugging surface and a plugging slot. The plugging slot is disposed on the board end plugging surface and comprises two interference sidewalls which are oppositely disposed. The terminal module is disposed in the board end insulating body. The housing is disposed on one side of the board end insulating body. A plugging bump member is provided on one side of the housing. The plugging bump member is disposed in the plugging slot. An interfering bump is provided on at least one side of the plugging bump member. The interfering bump interferes with at least one of the two interference sidewalls to increase the holding force between the housing and the board end insulating body.

An electrical connector includes a connector housing configured for mating with a corresponding counter-connector. Further, the electrical connector has an electrical contacting means arranged in the connector housing and configured for electrically contacting with the electrical conductor. The electrical contacting means is further configured for establishing an electrical contact with the counter-connector. Moreover, the electrical connector includes an insulative sleeve attachable to the electrical contacting means. The insulative sleeve is shaped to prevent a finger of a human from touching the electrical contacting means.

A connector plug, abutting structure of the same, and electrical connection mechanism having the same are provided. The connector plug includes a connection body and an outer casing member. The outer casing member is disposed outside the connection body and includes an inner casing, an outer casing movably fitted to the inner casing from outside, and a resilient component acting between the inner casing and the outer casing. At least one hook hole is disposed at the front end of the outer casing. At least one engaging arm is disposed on the inner casing and extends forward to form a hook portion. At least one engaging hole is disposed on a receptacle. When a plug is plugged into the receptacle, the hook portion becomes engaged with the engaging hole to achieve connection.

A cable connector includes a case, a fastener and an unlocking member. At least one side of the case has a texture area with a guide surface which is a smooth surface. The fastener is attached on the case and extended with a flexible arm. Part of the flexible arm is attached to the guide surface. The unlocking member includes a handle and a pushing block connected to the handle. The pushing block is sandwiched between the case and the flexible arm. When the unlocking member is pulled, the pushing block moves along the guide surface to separate the flexible arm from the case. When the unlocking member is released, the pushing block is pressed by the flexible arm to slide and return along the guide surface. The pushing block may return to original position without elasticity of a spring to simplify the structure and save the costs.

An electrical connector may include an insulating body and a housing. The housing may include walls defining an assembly space and surrounding external surfaces of the insulating body. The walls of the housing may include front and rear walls facing front and rear external surfaces of the insulating body, respectively. Portions of the front and rear walls of the housing may be spaced apart respectively from the front and rear external surfaces of the insulating body to form first and second docking slots in the assembly space. The front wall of the housing may include front docking holes in communication with the first docking slot, and the rear wall of the housing may include rear docking holes in communication with the second docking slot. The sizes and positions of the docking slots and the docking holes may be configured to enable a mating connector to be connected reversibly or irreversibly.

A high-voltage plug assembly includes a stationary first plug and a second plug that is movable along a connecting direction of the plugs. The plugs have mutually complementary plug contact elements. The second plug further has connection lines connected to its plug contact elements. An outlet direction of the connection lines extends perpendicular to the connecting direction. The second plug further has a position-securing element (PSE) that is displaceable along a displacement direction perpendicular to the connecting direction and that mechanically locks the plugs together when the plugs are connected while the PSE is displaced to a slide position. The PSE includes pairs of pins whose longitudinal axes are oriented in the PSE displacement direction and which are situated in pairs one behind the other in the PSE displacement direction. In the slide position in which the plugs are locked together, the pins respectively engage recesses of the plugs.

A board end connector and a connector assembly are provided. The board end connector comprises a board end connector body and a board end housing. The board end housing comprises a board end accommodating part and a buckling slot. Wherein the board end accommodating part accommodates the board end connector body. An end surface of the board end accommodating part in the first direction comprises a board end opening. The buckling slot is disposed at one side of the board end accommodating part. A buckling bump is provided in the buckling slot. A sidewall of the buckling bump in a second direction orthogonal to the first direction and away from the board end accommodating part comprises a board end buckling part. The board end buckling part comprises a retaining opening and a buckling elastic piece.

An electronic device and an input/output connector are disclosed. The device may include the input/output connector, which may include a housing including an opening, a cover that covers at least a portion of the opening, the cover connected to the housing by a hinge, and forming an external appearance of the electronic device together with the housing, an elastic body connected to the housing and the cover, and an insertion hole formed by the housing and the cover, into which a cable terminal is insertable for connection with an external device, wherein a size of the insertion hole is changeable according to the rotation of the cover.
