A connector for use in connecting a communication element to a transmission line in a wired pipe segment includes a first female end adapted to surround and make electrical contact with a coupler connection that extends away from a communication element of the coupler; a second female end adapted to receive an inner conductor of a coaxial cable; and an inner connection element formed on an inner surface of the connector adapted to electrically connect the coupler connection and the inner conductor, the inner connection element formed such that it does not completely surround at least one of the inner conductor and the coupler connection.

A multipurpose wire connection device includes a base plate, a conductive plate, a wire fixation screw, a fireproof box, a support, and a dustpan-shaped housing. The support is disposed on the base plate. The fireproof box includes a rear panel, a bottom panel, two side panels, and an inserted plate. The wire fixation screw is mounted on the conductive plate. The housing is fixed on the bottom plate by a housing fixing screw. The multipurpose wire connection device prevents sparking and red burning of a ground screw when lightning current passes therein, due to corroded contact in long-term exposure to wind and rain. It avoids fire and explosion accidents. It avoids screw corrosion and facilitates ground resistance measurement. The multipurpose wire connection device can also be used for electrical relay, division, and branching. It prevents fire, explosion, rain intrusion, and rust development. It is easy to disassemble.

A cartridge includes an outer case, partially filled with electrically insulating gel, and at least one electrically conductive track submerged in the insulating gel. Connection sets including at least one connector half and such a cartridge are also disclosed.

A heat sink assembly includes a casing having an opening, a main board accommodated in the casing, a heat sink mounted on the main board, an electrical connector mounted on the main board and exposed in the opening, a mating connector located outside the casing and connected to the electrical connector through the opening in a plugging manner, and a heat conductor, disposed inside the casing. The mating connector has a chip that is electrically connected to the electrical connector. One end of the heat conductor is connected to the heat sink, and the other end of the heat conductor is thermally connected to the electrical connector or the mating connector, so that heat generated by the chip during working can be transferred to the heat sink through the heat conductor, thereby reducing a temperature of the mating connector.

An electric hermetic compressor includes a hermetic terminal with terminal pins for electrical connection of a motor inside a hermetic housing. The hermetic terminal forms a cavity, and the compressor further includes a non-conductive sealing element, which defines an enclosed space in the cavity.

Disclosed herein is a connector for electrically connecting a feedthrough of a vacuum tool to a high voltage power source, the connector comprising: a connector wire assembly configured to be in electrical connection with a high voltage power source; and a connector insulator comprising a channel configured to extend into the connector insulator and to receive a feedthrough pin so as to electrically connect the connector wire assembly with the feedthrough pin; wherein the connector insulator is configured to engage with the feedthrough so that a boundary surface of the connector insulator extends substantially bi-directionally in the direction of the longitudinal axis of the channel.

A system for sealing a terminated solar cable, the system including: a solar cable; a connector terminating the solar cable, the connector including a locking feature; and a plug including a locking feature. When the locking feature of the plug engages the locking feature of the connector to lock the plug and the connector in a locked state, the solar cable is sealed to provide safety from voltage and protection from dust and liquid.
