Abstract

A closure device for connecting two parts is provided. The closure device includes a connector, a housing which includes a connector receptacle, into which the connector can be inserted in a closing direction for closing the closure device, a slide shiftably arranged at the housing, which for opening the closure device is shiftable along an opening direction different from the closing direction, a detent spring element which in a closed position of the closure device latchingly holds the connector at the housing and for opening the closure device can be moved out of engagement with the connector by shifting the slide in the opening direction, in order to release the connector from the housing, so that in an open position of the closure device the connector is separated from the housing, and at least one guide element which guides the connector on insertion into the connector receptacle for closing the closure device along the closing direction into the closed position and supports the connector against tilting relative to the closing direction when the slide is shifted for opening the closure device.

First claim

The invention claimed is:

1. A closure device for connecting two parts, comprising:
a connector,
a housing which comprises a connector receptacle, into which the connector is insertable in a closing direction for closing the closure device,
a slide shiftably arranged at the housing, which for opening the closure device is shiftable along an opening direction different from the closing direction,
a detent spring element which in a closed position of the closure device latchingly holds the connector at the housing and for opening the closure device can be moved out of engagement with the connector by shifting the slide in the opening direction, in order to release the connector from the housing, so that in an open position of the closure device the connector is separated from the housing, and
at least one guide element which guides the connector on insertion into the connector receptacle for closing the closure device along the closing direction into the closed position and supports the connector against tilting relative to the closing direction when the slide is shifted for opening the closure device,
wherein the connector and the slide each comprise at least one magnet, and
wherein in the closed position the at least one magnet of the connector and the at least one magnet of the slide oppose each other in a magnetically attracting manner and on opening are shifted with respect to each other along the opening direction such that a force of magnetic repulsion is exerted on the connector relative to the housing against the closing direction,
wherein the detent spring element is formed by a ring which is arranged on the slide and comprises a circumferential opening circumferentially interrupting a perimeter of the ring, and
wherein the connector comprises a pin insertable into the connector receptacle, the detent spring element circumferentially enclosing and elastically receiving the pin within an inner bore in the closed position of the closure device such that the detent spring element is in positive locking engagement with the pin, wherein, by shifting the slide in the opening direction, the detent spring element is moved with respect to the pin such that the pin passes through said opening of the detent spring element for releasing the positive locking engagement between the detent spring element and the pin.

2. The closure device according to claim 1 , wherein the at least one guide element is arranged at the connector receptacle.

3. The closure device according to claim 1 , wherein the connector receptacle is formed by a recess at the housing.

4. The closure device according to claim 1 , wherein the at least one guide element is formed by a surface portion at the connector receptacle of the housing, which extends along the closing direction and in the closed position fully is in contact with the connector.

5. The closure device according to claim 1 , wherein the at least one guide element is arranged at the housing such that the guide element supports the connector relative to the housing when a load acts on the connector in the opening direction.

6. The closure device according to claim 1 , wherein at the pin a first latching portion is arranged, which in the closed position latchingly is in engagement with a second latching portion at the housing or the slide.

7. The closure device according to claim 6 , wherein in the closed position the pin rests against the at least one guide element.

8. The closure device according to claim 6 , wherein the first latching portion is arranged at the pin circumferentially around the closing direction.

9. The closure device according to claim 1 , wherein the detent spring element is spring-elastic in a direction transverse to the closing direction such that on closing of the closure device the detent spring element can be spread in the direction transverse to the closing direction.

10. The closure device according to claim 9 , wherein by shifting the slide in the opening direction, the detent spring element is brought out of engagement with the pin of the connector.

11. The closure device according to claim 9 , wherein when shifting the slide in the opening direction, the detent spring element is shifted together with the slide.

12. The closure device according to claim 1 , wherein the detent spring element is formed integrally with the slide.

13. The closure device according to claim 1 , wherein in the closed position the connector is rotationally movably held at the housing around the closing direction.

14. The closure device according to claim 1 , wherein in the direction of a position in which the connector is mechanically connectable with the housing for closing the closure device, the slide is mechanically, pneumatically or magnetically biased with respect to the housing.
