A plug connector has a main body, an actuating element, and a contact carrier accommodated in the main body. By pulling on the actuating element against the plugging direction of the plug connector, a locking connection to a mating plug connector can be released and the plug connector can be removed from the mating plug connector. The spring strength of locking arms that enable the locking connection to a mating plug connector can be adjusted by the actuating element. As a result of a spring strength reduced in such a way, the locking connection can be released.

An electronic device includes a printed circuit board and a card holder. The card holder is configured to hold a function card, and the printed circuit board is provided with a groove. The card holder is disposed in the groove. A bottom surface of the groove is provided with n metal solder pads and n printed wires. The n metal solder pads are electrically connected to the n printed wires in a one-to-one correspondence. N terminals in a one-to-one correspondence to the n metal solder pads are disposed on the card holder. Each terminal is provided with a first contact and a second contact. The first contact is connected to and in contact with one of the n metal solder pads. The second contact is configured to connect to and be in contact with a metal contact of the function card placed in the card holder.

An electric compressor includes a terminal structure. The terminal structure may include a busbar assembly electrically connected to an inverter and a terminal electrically connected to a motor part. The terminal structure may include at least one electrical connection member. Contact plates may be electrically connected to each end of the electric connection member. The busbar assembly for electrically connecting the terminal and the inverter device may include a plurality of busbars having a large surface area. When high current is applied to the electric compressor, as the surface area of respective members brought into contact with each other for electric connection increases, contact heat resistance decreases, which makes it possible to apply a high current without increasing the size of the terminal.

A coupling system and related methods are disclosed. The system has a first plug detachably coupled to a first housing, and a first socket detachably coupled to a second housing. The first socket is configured to receive the first plug. The system is movable between a first configuration wherein the first and second housings are not engaged and a second configuration wherein the first and second housings are engaged and the first plug and the first socket are coupled together.

A plug connector includes a housing holding plug connector contacts and a latch assembly. The latch assembly includes a latch with a latch beam movable between a latched position and an unlatched position and an actuator for moving the latch. The latch assembly includes a pull tab extending from the rear of the housing having first and second attachment members. The first attachment member is coupled to the actuator proximate to a first end of the housing and is movable in a rearward pulling direction to move the actuator and actuate the latch to the unlatched position. The first attachment member pulls the first end of the housing to unmate the housing from the mating connector. The second attachment member is coupled to a second end of the housing to pull the second end of the housing and unmate the housing from the mating connector.

A cable connector, especially an IDC (Insulation Displacement Connector) connector, has an insulating body and an abutment bridge. The insulating body includes a housing and locking elements integrally manufactured with the housing. The locking elements include a lever and a bearing axle. The lever is doubly connected to the housing. A bearing axle of the locking element is designed to be inserted into a bearing recess of the abutment bridge.

A female terminal includes a housing main body, a sealing member mounted to the fitting protrusion of the housing main body and sealing between the fitting protrusion and the fitted hood portion of a male housing, and a lock arm including a cantilever-shaped elastic arm portion extending from an outer peripheral surface of the housing main body to a fitting side with the male housing and having a locking portion engaged with and/or disengaged from a locking protrusion formed on the male housing. A protective wall integrally provided at a base of the elastic arm portion is formed on an outer surface of the housing main body, and is provided over the housing main body at a position in the housing main body facing a gap between the hood portion and the housing main body when the fitting protrusion of the housing main body is fitted to the hood portion.

Electrical connector apparatus can have at least two pins, at least one side slot, and at least one latch, facilitating a secure physical connection and a secure electrical connection with a printed circuit board or other unit. The electrical connector apparatus can be a non-staggered dual row surface mount terminal connector.
