A contact clamp for connecting a stripped conductor end that is insertable into the contact clamp from an insertion end, comprising: a retaining frame with a contact portion, to which the conductor end is electrically connectable; a clamping spring comprising a clamping leg and an actuating leg and being configured in the form of a rocker lever which is pivotally mounted in the retaining frame and can be pivoted back and forth between an open pivotal position (Fig. 1) and a closed pivotal position (Fig. 2); wherein, when in the closed pivotal position, the clamping leg clamps the conductor end against the contact portion, when the conductor end is inserted to the target contact position (FIG. 11) in the contact clamp, in order to establish the electrical contact between the conductor end and the contact portion, wherein, when in the open pivotal position, the clamping leg is pivoted away from the contact portion so as to clear the contact area in the contact clamp, so that in the open pivotal position the conductor end can be freely inserted into the contact clamp on the one hand, and on the other it is released so that it can be removed from the contact clamp; and wherein latching means (80a, 80b, 34a, 34b) are provided between the clamp spring and the retaining frame, and wherein in the closed pivotal position the clamp spring is latched on the retaining frame; characterized in that in the closed, latched pivotal position, the clamping leg extends at an angle (γ) relative to the contact portion, as seen in the insertion direction of the conductor end; and the clamping leg is of resiliently movable nature such that when in its closed, latched pivotal position, the conductor end can be introduced into the contact clamp to the target contact position by urging the clamping leg to resiliently open. a retaining frame with a contact portion, to which the conductor end is electrically connectable; a clamping spring comprising a clamping leg and an actuating leg and being configured in the form of a rocker lever which is pivotally mounted in the retaining frame and can be pivoted back and forth between an open pivotal position (Fig. 1) and a closed pivotal position (Fig. 2); wherein, when in the closed pivotal position, the clamping leg clamps the conductor end against the contact portion, when the conductor end is inserted to the target contact position (FIG. 11) in the contact clamp, in order to establish the electrical contact between the conductor end and the contact portion, wherein, when in the open pivotal position, the clamping leg is pivoted away from the contact portion so as to clear the contact area in the contact clamp, so that in the open pivotal position the conductor end can be freely inserted into the contact clamp on the one hand, and on the other it is released so that it can be removed from the contact clamp; and wherein latching means (80a, 80b, 34a, 34b) are provided between the clamp spring and the retaining frame, and wherein in the closed pivotal position the clamp spring is latched on the retaining frame; wherein, when in the closed pivotal position, the clamping leg clamps the conductor end against the contact portion, when the conductor end is inserted to the target contact position (FIG. 11) in the contact clamp, in order to establish the electrical contact between the conductor end and the contact portion, wherein, when in the open pivotal position, the clamping leg is pivoted away from the contact portion so as to clear the contact area in the contact clamp, so that in the open pivotal position the conductor end can be freely inserted into the contact clamp on the one hand, and on the other it is released so that it can be removed from the contact clamp; and wherein latching means (80a, 80b, 34a, 34b) are provided between the clamp spring and the retaining frame, and wherein in the closed pivotal position the clamp spring is latched on the retaining frame; in the closed, latched pivotal position, the clamping leg extends at an angle (γ) relative to the contact portion, as seen in the insertion direction of the conductor end; and the clamping leg is of resiliently movable nature such that when in its closed, latched pivotal position, the conductor end can be introduced into the contact clamp to the target contact position by urging the clamping leg to resiliently open.
