An electric terminal block having a block housing, two conductor connection elements, two current bars, and two additional current bar pieces. Each current bar has a connection portion, and first and second contact portions, each connection portion being paired with a conductor connection element. To obtain a reliable switching sequence when plugging and unplugging an operating or test plug, the terminal housing is equipped with two spring elements, each of which has a connection portion and an elastic contact portion; each of the spring elements is electrically connected to one of the current bar pieces; the contact portions together form a second contact region for receiving the plug, and being mutually spaced when the plug is not plugged in. The contact region of the spring elements is arranged in front of the contact region of the current bars in the plug-in direction of the plug.

An electric terminal block having a terminal housing, two conductor connection elements in the housing, and two current bars. Each current bar has a connection portion and a resilient contact portion. Each connection portion is paired with a respective conductor connection element, and the contact portions together form a contact region for receiving and contacting the plug of a test plug or disconnecting plug. The contact portions contact each other when no plug is plugged in such that the two conductor connection elements are electrically connected together via the two current bars. A transverse connection between two conductor connection elements of two adjacent terminal blocks is produced automatically when a test plug or disconnecting plug is plugged onto the terminal blocks. The terminal housing has two spring elements that have a resilient contact portion; the contact portions of the spring elements together form an additional contact region for the plug.

The present invention provides a receptacle connector including: a grounding portion configured to ground a connection object; and a ground connection terminal that is configured to be switchably held in a first state in which the ground connection terminal is electrically separated from the grounding portion, or in a second state in which the ground connection terminal is electrically brought into conduction with the grounding portion. The ground connection terminal is switched between the first state and the second state in operative association with interlining of the plug connector and the fitting portion. In the first state, the grounding terminal and the grounding portion are electrically separated. In the second state, the grounding terminal and the grounding portion are electrically brought into conduction with each other through the ground connection terminal.

A barrel terminal has one end for inserting a mating member and the other end for connecting a cable. The barrel terminal includes a contact portion, a connecting portion, and a buffer portion connecting the contact portion and the connecting portion. The contact portion has multiple contact elastic pieces, and the contact elastic pieces are used for electrically contacting the mating member. The connecting portion is used for connecting the cable. The buffer portion has multiple absorption portions. The absorption portions absorb the deformation stress of the connecting portion to prevent the stress from being transferred to the contact portion, to avoid the deformation of the contact elastic pieces, so as not to cause the reduction of the contact area between the contact elastic pieces and the abutment terminal, and to prevent reduction of a clamping force of the barrel terminal to the mating member.

A connector is arranged in a hole portion of a retaining member and is fitted as a floating connector to a mating connector. For example, the connector includes a plurality of abutment portions, which are brought into abutment against the hole portion when the connector is arranged in the hole portion, and a plurality of biasing portions, which are configured to bias the plurality of abutment portions in respective abutment directions relative to a main outer surface portion of a shell. The plurality of abutment portions include a first abutment portion and a second abutment portion which are formed in an opposite side over a main plane being a plane which includes a main center line and is perpendicular to the main outer surface portion, and a third abutment portion which is formed at a position forming a triangle with the first abutment portion and the second abutment portion.

The present application discloses an AC power socket, including a socket body having a first pin and a second pin extending in the same direction; and a fixing structure configured to connect the socket body with a circuit board in a snap-fit manner so as to fix the socket body with the circuit board. The AC power socket is connected with the circuit board in a snap-fit manner before being welded thereto. Therefore, there is no need to manually place a weight on the AC power socket at the time of welding, which can prevent the floating of the AC power socket. Meanwhile, after the welding the snap-fit connection can enhance the relative securable stability between the AC power socket and the circuit board, and reduce the breakage rate of the tin-soldered surface as a result of repeated plug-in and plug-out.

Circuits, methods, and apparatus that may provide audio jacks capable of providing a sufficient retention force to avoid some inadvertent extractions of an audio plug. Examples may also provide audio jacks that may be readily assembled. Other examples may provide other types of connectors. These audio jacks or other connectors may provide contact structures having one or more contacts, each having a contact support to increase contact retention force. Different materials may be used to form the contacts and the contact supports. In this way, contacts may be formed using a highly conductive material, while the contact supports may be formed of a material having good spring characteristics. While such a contact may not be able to provide an adequate retention force on its own, the use of a contact support may sufficiently increase the retention force to prevent accidental extractions of an audio plug or other connector.

A shockproof electrical socket is connected to a plug comprising a first latch and a second latch. The socket comprises a shell, a first elastic sheet, a second elastic sheet, a first elastic contact mechanism configured to connect the first elastic sheet and the first latch, and a second elastic contact mechanism configured to connect the second elastic sheet and the second latch. The first elastic contact mechanism comprises a first insulation block connected to the shell through a first elastic piece. The first elastic sheet is connected to the shell through a second elastic piece. The second elastic contact mechanism comprises a second insulation block connected to the shell through a third elastic piece. The second elastic sheet is connected to the shell through a fourth elastic piece.

The present invention relates to an electrical plug connector for a safety restraint system, preferably for an airbag ignition system. The plug connector includes at least two contact terminals assigned to the plug connector and a shorting clip that is configured to short-circuit the at least two contact terminals in an uncoupled or incorrectly coupled condition of the plug connector. The shorting clip includes at least two contact blades. Each contact blade is electrically connected with one of the at least two contact terminals. Each of the contact blades includes at least one cutting edge. The cutting edges contact each other such that one edge cuts the other when the plug connector is in an uncoupled or incorrectly coupled condition.
