An electrical conductor connection element has a contact carrier, at least one first contact element and at least one second contact element. An electrical conductor can be connected to and contacted with the conductor connection element on the first contact element. The second contact element is connected to the first contact element and guided on the outside of the contact carrier. The conductor connection element furthermore has a separation point which serves to separate the electrical connection of the first contact element to the second contact element.

The invention relates to a switch spring arrangement in a card reader, comprising a contact carrier which is integrated into the card reader and includes a plurality of pockets, open on one side, for accommodating holding elements of a spring contact element, and a spring contact element that has two mounting arms to be secured in the contact carrier as well as a spring arm which can be actuated by a card and is placed between the mounting arms.

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.

Various embodiments include a plug receptacle for an electrical plug-in connection for receiving a plug with electrical plug conductor comprising a contact region for electrical connection to the plug receptacle comprising: a housing with an insertion region into which the plug can be releasably inserted; an electrical plug receptacle conductor rigidly arranged in the housing; and an electrical connecting conductor floating in the housing configured to electrically connect the plug receptacle conductor to the plug conductor. The electrical connecting conductor exerts a connecting force onto the contact region of the plug conductor once inserted into the plug receptacle. The connecting force runs substantially orthogonally in relation to said contact region.

A plug electrical connector including an insulator, a plurality of elastic terminals, at least one shielding spring, and an outer shell is provided. The elastic terminals are disposed in the insulator and arranged along an axial direction. The elastic terminals includes at least one grounding terminal arranged at a first position or a last position of the elastic terminals. The shielding spring is assembled to an exterior surface of the insulator. A portion of the shielding spring on the axial direction is disposed on a deformable path of the grounding terminal. The insulator, the elastic terminals, and the shielding spring are accommodated in the outer shell.

A shielded coaxial connector including a central conductor and a waveguide to shield the central conductor from RF signals.

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.

A bread board includes a first layer, a second layer, and connectors. The first layer includes a plurality of first regions each including at least one terminal detacher which is electrically connected to a terminal, and the terminal detachers contained in an identical one first region from among the plurality of first regions are mutually electrically connected, but are electrically insulated from the terminal detachers contained in other first regions. The second layer includes a plurality of second regions and forms a multilayer structure with the first layer. Each of the connectors electrically connects the second region of the second layer and a predetermined first region of the first layer, and the plurality of first regions which are mutually insulated are electrically connected through the connector and the second region.

An electrical connector includes an insulating housing and a clamping terminal. The insulating housing has a first side wall and a second side wall opposite to the first side wall. The insulating housing has a mating cavity opening forwardly along a front-to-back direction. The first side wall and the second side wall are disposed around the mating cavity. The clamping terminal has a main body and a resilient clamping arm extending along a transverse direction perpendicular to the front-to-back direction from the main body. The clamping arm has a contacting portion exposed in the mating cavity. The first side wall has an assembling slot, and the second side wall has a movable slot. The main body is received in the assembly slot, and a head portion of the clamping arm is movable in the movable slot.

The invention concerns a method for locating a fault affecting an electrical appliance that comprises a communication interface and a female electrical connector, the female electrical connector comprising at least one conductive element mounted movable between an active position and a rest position, the female electrical connector comprising test means connected to the conductive element when same is in the rest position; the locating method comprising: a disconnection step; a test step consisting of testing the communication interface by cooperating with the test means of the female electrical connector; a locating step consisting of locating the fault in the electrical appliance or in an external element.
