Electrical connector having a lever mating assist with blocking system
View Patent ↗An electrical plug-in connector with a casing, with a lever rotatably mounted on the casing. The lever has a guideway provided for guiding a guide element of a second casing, with the guide element being guided in the guideway upon rotation of the lever and the second casing being pulled from a pre-assembly position with regard to the casing into an end position. The casing has a flexible blocking element, an insertion space for introducing the guide element into the guideway being provided, the blocking element having an actuating surface, the actuating surface in a rest position of the blocking element projecting into the insertion space. The lever has a blocking surface, the blocking element having a second blocking surface, with, in a rest position of the lever and in a rest position of the blocking element, the second blocking surface of the blocking element being associated with the blocking surface of the lever and blocking a movement of the lever from the rest position into an end position.
1. An electrical plug-in connector with a casing, with a lever rotatably mounted on the casing, the lever having a guideway, the guideway being provided for guiding a guide element of a second casing, with the guide element being guided in the guideway upon rotation of the lever and the second casing being pulled from a pre-assembly position with regard to the casing into an end position, the casing having a flexible blocking element, an insertion space for introducing the guide element into the guideway being provided, the blocking element having an actuating surface, the actuating surface in a rest position of the blocking element projecting into the insertion space, the lever having a blocking surface, the blocking element having a second blocking surface, with, in a rest position of the lever and in a rest position of the blocking element, the second blocking surface of the blocking element being associated with the blocking surface of the lever and blocking a movement of the lever from the rest position into an end position, the blocking element being formed such that the guide element upon introduction of the second casing into the pre-assembly position in relation to the casing being guided into the insertion space and in so doing the guide element acting on the actuating surface such that the blocking element is moved into a release position, so that the position of the second blocking surface of the blocking element relative to the blocking surface of the lever is changed such that the lever is released for a movement into the end position.
2. A plug-in connector according to claim 1 , wherein the lever is arranged between an inner region of the casing and the blocking element, the insertion space being provided between the inner region of the casing and the lever, the blocking element being guided past the blocking surface of the lever, and the actuating surface being arranged between the lever and the inner region of the casing in the rest position of the blocking element and the lever.
3. A plug-in connector according to claim 2 , further comprising a casing wall having on the inner side a first guide contour in the form of a partial circle, the lever having a second guide contour in the form of a partial circle, the first and the second guide contour being associated with each other and the first guide contour guiding the second guide contour on at least one partial circular path.
4. A plug-in connector according to claim 3 , wherein the lever has on an outer side a recess in which the blocking element is arranged upon the movement of the lever from the latching position into the end position.
5. A plug-in connector according to claim 4 , wherein the blocking element adjoins the second blocking surface having a sliding surface which is arranged inclined, the sliding surface and the second blocking surface being arranged such that in the rest position of the blocking element and of the lever the second blocking surface of the blocking element is associated with the blocking surface of the lever, and in the release position of the blocking element the sliding surface being associated with the blocking surface of the lever, so that the lever can be moved with low force from the latching position into the end position, the blocking surface of the lever sliding across the sliding surface and pushing the blocking element away from the blocking surface of the lever.
6. A plug-in connector according to claim 1 , wherein the blocking element being designed as part of a flexible outer wall of the casing.
7. A plug-in connector according to claim 1 , wherein the actuating surface of the blocking element is arranged inclined to the direction of movement of the guide element upon introduction into the insertion space, which facilitates deflection of the blocking element by the guide element.
8. A plug-in connector according to claim 1 , wherein the lever has a latch recess, the blocking surface being formed on an inner side of the latch recess, and the blocking element in the rest position being guided through the latch recess.
9. A plug-in connector according to claim 1 , further comprising a safety catch being movably mounted on the casing, the safety catch being movable into a blocking position, the safety catch in the blocking position holding the lever securely in the end position.
10. A plug-in connector according to claim 9 , wherein the safety catch is displaceably mounted on the casing via a sliding guide and having a projection which holds the lever securely in the end position.
