A wire connection terminal structure includes a seat body and a conductive clip disposed therein. One end of the seat body has an extending side and a recessed side and a slope formed between the extending side and the recessed side. The conductive clip has a holding mouth. The slope is formed with a wire plug-in opening aligned with the holding mouth. A wire plug-in protection wall is formed on an edge of the recessed side. The wire plug-in protection wall protrudes in a direction as an extending direction of the extending side. The slope and the wire plug-in protection wall define a recessed configuration on the end of the seat body. The wire plug-in protection wall on the outer edge of the wire plug-in opening provides a shielding and guidance effect so that the conductive wire can be easily aimed at and plugged into the wire plug-in opening.

A connection arrangement for connecting an electrical conductor includes: a housing; a busbar; a clamping spring including a clamping leg transferrable into a clamping position and into a release position; a conductor connection space formed between a section of the busbar and the clamping leg of the clamping spring; a displaceably arranged guide element, which is in operative connection with the clamping leg of the clamping spring, the clamping leg being holdable in the release position by the guide element; a release element, which, in the release position of the clamping leg of the clamping spring, is in engagement with the guide element, the release element during insertion of the conductor to be connected into the conductor connection space being actuatable thereby such that the release element comes out of engagement with the guide element and the guide element is displaceable by a spring force of the clamping leg.

The invention relates to a push-in clamp retainer for an electric connector element with a lead wire receptacle which is at least partly encircled by a surrounding wall. In a lateral direction, a push-in clamp assembly includes such a push-in clamp retainer and a separate spring member having a first end and second end, The invention also relates to an electric connector element having a spring release member and a push-in clamp assembly. The invention involves the implementation of at least one receiving member into at least one contraction of the push-in clamp retainer, combining such a push-in clamp retainer with a spring member to form the push-in clamp assembly, and adding a spring release member to the push-in clamp assembly to obtain the electric connector element.

A conductor terminal includes a rubber shell, control pieces, and clamping springs. A connecting section is formed in a height direction of each of the clamping springs. Each connecting section is connected between a highest position and a lowest position of each of the clamping springs. A total length of each connecting section is greater than a distance between the highest position and the lowest position of each of the clamping springs, making each connecting section more extended and disposed within the entire clamping spring. Moreover, the conductor terminal is flattened, which increases the size in the plug-in direction and significantly reduces the overall height, making the wiring connection more efficient and tighter. In this way, the conductor terminal is narrowed, and the conductor terminal product is made lighter and thinner.

A contact spring assembly for the self-locking contacting of a wire of an electrical conductor is provided that includes a support wall made of a conductive material; a contact spring which has a base leg held stationary with respect to the support wall and has a clamping leg that is connected to the base leg by a curve portion and forms, together with the support wall, an insertion receptacle for the wire of the conductor, the insertion receptacle being tapered in the insertion direction, and the clamping leg having at its free end a gripping edge for the wire; anda release element guided for translation relative to the support wall in the insertion direction and having an actuation arm, the free end of which, in a release position, acts on a stop formed by a curved portion of the clamping leg and holds the clamping leg, against the spring force, in a position in which the clamping leg is bent back against the base leg; wherein the clamping leg has, in a portion adjoining the stop, a bend point which is curved in the direction opposite the direction of curvature of the curve portion and which is followed, toward the stop, by an additional bend point curved in the same direction.

A wire clip electrical connector, comprising a connector body, an elastic clip piece and an elastic conductive piece disposed in the connector body, and a push rod slidingly matched with the connector body. A wire insertion hole is formed in the connector body, and an elastic clip piece and an elastic conductive piece are located on two sides of the wire insertion hole, and the push rod is provided with a spring piece pressing structure and a stopping structure. According to the above design, the wire is inserted into the wire insertion hole, and the push rod slides relative to the connector body, and the elastic pressing structure on the elastic bar acts on the wire elastic piece, and the wire elastic piece presses the wire on the elastic conductive piece, and the stopping structure restricts the decoupling to achieve a stable connection between the electrical connector and the wire.

A current bar for a connection arrangement for connecting an electrical conductor includes: a clamping portion, against which the electrical conductor inserted into the connection arrangement in an insertion direction is clampable. The clamping portion has a first function zone, a second function zone, and a third function zone. In an embodiment, viewed in the insertion direction, the second function zone is formed below the first function zone, and the third function zone is formed below the second function zone.

A conductor connection terminal with a spring-force clamping connection, which has a busbar and a clamping spring for connecting an electrical conductor to the busbar by the clamping spring. An actuator acts on an actuation section of the clamping spring for displacing a clamping leg of the clamping spring from a clamping position to an open position. The actuator has a first pusher section with a first actuation contour and a second pusher section with a second actuation contour. The actuator displaces the clamping leg by a first displacement distance through interaction of the first actuation contour with the first effective contour when the actuator is displaced by a first actuation distance, and displace the clamping leg of the clamping spring by a second displacement distance through interaction of the second actuation contour with the second effective contour when the actuator is displaced by a second actuation distance.
