A pluggable free-space photoelectric hybrid connector including a female connector and a male connector is provided. The female connector includes a first insulating substrate, metal elastic clips, a first circuit board, and a first optical communication module. An insertion cavity is formed at the front end of the first insulating substrate, and a first fiber mounting hole and first electrode mounting holes are formed at the rear end thereof. The metal elastic clips are mounted in the first electrode mounting holes respectively, where contact portions of at least one set of metal elastic clips are exposed from the top of the insertion cavity, and contact portions of at least another set of metal elastic clips are exposed from the bottom of the insertion cavity. The first circuit board is mounted at the rear end of the first insulating substrate and is electrically connected to the metal elastic clips.

Provided is a connector including a surrounding wall with an improved strength against an outward force. The connector of the invention includes a contact that contacts a counter contact of a counter connector, a housing to which the contact is fitted and attached, and a surrounding wall disposed to surround the housing. A gap is provided between the housing and the surrounding wall, and in a connector fitting state, the surrounding wall is in contact with a counter surrounding wall of the counter connector that has entered the gap. The surrounding wall is provided with a protrusion portion protruding outward in a second direction intersecting a first direction, and an end portion on a board side of the protrusion portion in the first direction is in contact with a board.

A power adapter assembly structure is disclosed and includes a housing, a circuit board, a socket and an elastic element. The circuit board including a first abutting surface and the socket including a second abutting surface are fastened in the housing. The elastic element connected between the circuit board and the socket includes a main body, a first hanging arm and a second hanging arm. The first hanging arm and the second hanging arm are disposed at two opposite ends of the main body, and constantly abuts the first abutting surface and the second abutting surface, respectively. A first gap is formed between the main body and the first abutting surface, and less than a first length of the first hanging arm. A second gap is formed between the main body and the second abutting surface, and less than a second length of the second hanging arm.

An apparatus for grounding a heatsink utilizing an EMC spring press-fit pin includes a printed circuit board, a logic chip, a heatsink, and a grounding member, where the grounding member includes an integrated spring and a first terminal pin at a first end of the grounding member. The logic chip is electrically coupled to the printed circuit board and the heatsink is disposed on a top surface of the logic chip. The first terminal pin at the first end of the grounding member is disposed in a plated-through hole of the printed circuit, where the grounding member is configured to electrically couple the heatsink to the printed circuit board.

An electrical connector includes an insulating body, a number of first conductive terminals and a number of second conductive terminals. The insulating body includes a mating slot for receiving a mating board. Each first conductive terminal includes a first extension arm having a first mating portion. Each second conductive terminal includes a second extension arm having a second mating portion. The first mating portion and the second mating portion are adapted to jointly clamp the mating board. Extension directions of the first extension arm and the second extension arm are opposite to each other. The first conductive terminals or the second conductive terminals include at least one radio frequency signal terminal for transmitting a radio frequency signal.

Apparatuses, systems, and methods for coupling a capacitor to a printed circuit board assembly. One example apparatus can include a number of capacitors and a connector coupled to the number of capacitors, the connector configured to removably couple the number of capacitors to a printed circuit board assembly of a solid state drive.

In some embodiments, an irrigation control device is provided that includes adjacent terminal connector rows having a ridge portion between the rows, where the ridge portion is configured to support and guide wires to electrical connection pads of one row, and to support these wires above wires retained in another row of electrical connection pads. In some embodiments, the ridge portion offsets the wires from the different rows in the horizontal plane.

A memory module testing system operating in a vibratory environment can retain a memory module in place in a memory socket using both socket latches and a retainer clip. The retainer clip can attach to a module support tower of the memory socket. The retainer clip can have a flexible multi-spring structure forming a three-axis vibration dampening system that can prevent the socket latches from opening while testing in the test environment. The retainer clip can secure the socket latches using an upper flange and a lower flange to prevent unintended motion of the socket latches. The retainer clip can be secured to the module support towers at the ends of the memory socket using clip arms and clip arm tips to attach to the module support towers.
