Devices and methods for a sealed electrical connector are described herein. Some embodiments include a spring connecting a first PCB to a second PCB, wherein the spring includes a first end portion in contact with the first PCB, a second end portion in contact with the second PCB, and a middle portion extending between the first end portion and the second end portion, a spacer surrounding the middle portion of the spring, a first seal seated in a first groove of the spacer and in contact with the first PCB, and a second seal seated in a second groove of the spacer and in contact with the second PCB.

A connector includes a housing to be assembled to a wall portion of a box-shaped body, a bus bar having a fastened portion disposed inside the wall portion and is to be connected to a terminal fitting by fastening using a bolt, and a nut held by the housing with a gap between the nut and the fastened portion into which the terminal fitting is capable of being inserted and engaged with the bolt to fasten the fastened portion and the terminal fitting inserted into the gap together.

An electronic assembly is provided and includes a host circuit board having an upper surface and board contacts on the upper surface. The upper surface has a mounting area. The electronic assembly includes a socket connector mounted to the host circuit board at the mounting area. The socket connector includes a socket housing holding a plurality of socket contacts. Each socket contact has an upper contact portion and a lower contact portion. The lower contact portion is electrically connected to the corresponding board contact of the host circuit board. The socket contact is compressible between the upper contact portion and the lower contact portion. The socket housing includes coolant channels configured to receive coolant. The electronic assembly includes an electronic package coupled to the socket connector. The electronic package has a lower surface and package contacts on the lower surface. The package contacts are electrically connected to the upper contact portions of the socket contacts.

A connector includes a terminal fitting, a housing that houses the terminal fitting at a housing complete position, and a terminal retaining member that, at an assembling complete position to the housing, retains the terminal fitting remaining at the housing complete position. The terminal fitting includes a penetration hole. The terminal retaining member includes a retaining protrusion that is, at the assembling complete position, inserted into the penetration hole at the housing complete position, and retains the terminal fitting while the terminal fitting remains at that position. The penetration hole is formed to have a left-right asymmetric shape including a first hole part on the left side and a second hole part having a shape different from a shape of the first hole part and arranged on the right side of the first hole part.

A waterproof power plug includes a mounting frame, first and second conductive terminals, a fuse, and a fuse cover which are mounted inside the mounting frame. The fuse is electrically connected to the second conductive terminal. The mounting frame is provided with a mounting groove for exposing the fuse, and the fuse cover is mounted in the mounting groove to cover or expose the fuse. The power plug further includes a housing opened with a window for slidably operating the fuse cover, and a waterproof cover is mounted in the window. Therefore, the fuse cover is arranged on the mounting groove and the waterproof cover is further covered on the fuse cover, which provides multiple waterproof protections. The power plug has a good sealing performance and waterproof performance, which also helps to improve the overall waterproof performance and work safety of the string light with the power plug.

An adapter may be configured to connect a battery and an electrical device to each other. The adapter may include a control board; a battery-side terminal mounted on a first surface of the control board and configured to be electrically connectable to the battery; and a device-side terminal mounted on a second surface of the control board and configured to be electrically connectable to the electrical device, the second surface being opposite from the first surface.

A plug for use in an electrical connector system includes a handle body assembly comprising a handle body and a flange disposed on an end of the handle body. The flange defines a plurality of openings. A sleeve assembly includes a sleeve and a flange disposed on an end of the sleeve. The flange on the sleeve defines a plurality of openings. The openings in the flange on the handle body are aligned with the openings in the flange on the sleeve. A contact assembly is disposed, at least partially, in the sleeve of the sleeve assembly. The contact assembly includes a contact holder and a plurality of contacts coupled to the contact holder. Fasteners extend through the aligned openings in the flanges to secure the handle body assembly to the sleeve assembly.

An electrical connector including an insulating body, multiple terminals, a shell, and a sealing adhesive is provided. The terminals are disposed in the insulating body. The shell is assembled to the insulating body. The shell has an insulative exterior shell, surrounding the insulating body and the terminals. Portions of the insulating body and the terminals protruding from a front side of the insulative exterior shell are configured to be connected to another electrical connector. The sealing adhesive is filled between the shell and the insulating body and located at a rear side of the insulative exterior shell.

An object of the present invention is to provide an electronic control unit that curbs overflow of a sealant at a three-way junction of the sealant in the vicinity of a connector. The electronic control unit includes a first seal part 51 that seals between a base member 40 and a cover member 30, a second seal part 52 that seals between the base member 40 and a connector housing 20, and a third seal part 53 that is connected to the first seal part 51 and the second seal part 52 and seals between the cover member 30 and the connector housing 20. In a part (three-way junction) where the first seal part 51, the second seal part 52, and the third seal part 53 intersect, a space part 41JA1 that is connected to the recessed part 41 and recessed further from a surface forming the recessed part 41 is formed.

A connector frame for a connector assembly for an electric connection of a device in a connector-to-counter-connector configuration, including: at least one connector frame opening, in which the connector frame opening is configured to receive at least one terminal connector frame and/or at least one terminal connector by a form-fit and/or force-fit connection.
