Abstract

Claims (25)

1. A one-part male bayonet connector with which at least one first component and a second component are releasably connectable with each other in a non-destructive manner via an opening in each of the at least one first component and the second component, the bayonet connector having a T-like form in a lateral view, wherein

the bayonet connector comprises a head, a central shaft extending from there and two radially opposite thread webs extending from the central shaft and being configured rigidly, wherein each of the two thread webs comprises a fastening means of the bayonet connector facing the head, so that by means of a form-fit bayonet connection, the at least one first component and the second component are fastenable between a bottom side of the head and the fastening means of the thread webs such that the bottom side of the head is configured to be arranged at a side of the at least one first component facing away from the second component and the fastening means are configured to be arranged in recesses of the second component or at a side of the second component facing away from the at least one first component, wherein

the two thread webs define a right-handed thread or a left-handed thread and include a pitch angle a with respect to a plane that is normal to a central longitudinal axis of the central shaft in the range of 30°<α<50°, wherein

the fastening means of each thread web is a locking web or a semi-spherical like projection and

the two thread webs include a continuously decreasing radial extension in the direction facing away from the head of the shaft, so that the radial extension of the thread webs at the end of the shaft which faces away from the head has reduced to zero and, in an axial direction opposite of the head, the bayonet connector ends in a finder tip which is formed pointed, rounded, blunt or angular.

2. The bayonet connector according to claim 1 , in which the two thread webs define a steep thread so that the bayonet connector is completely fastenable with a rotation about its longitudinal axis by a rotation angle β of β<360°.

3. The bayonet connector according to claim 1 in which the two thread webs have a smaller radial extension than the head.

4. The bayonet connector according to claim 1 , which comprises at least one pre-positioning web which extends from a flange-like offset bottom side of the head in radial direction in order to be lockable at an opening edge of the first component.

5. The bayonet connector according to claim 1 which consists of plastic or metal.

6. A component composite of at least one first component and a second component and the bayonet connector according to claim 1 , in which the first component is arranged adjacent to the head of the bayonet connector and includes a first opening and the second component includes a key hole, so that the head rests at the first component, the central shaft with the thread webs passes through the first opening and the key hole and the thread webs are locked at the second component in a way facing away from the head.

7. A component composite of at least one first component and the bayonet connector according to claim 1 , in which the bayonet connector is releasably locked with a plurality of pre-positioning webs in the form of bumps of a flange-like projection at a bottom side of the head of the bayonet connector at an edge of a first opening of the first component.

8. A connection method for at least one first component with a first opening and a second component with a keyhole with the bayonet connector according to claim 1 which includes the following steps:

a. stack-like arranging of the first and the second component that the first opening and the keyhole are aligned with each other,

b. plugging the central shaft with the thread webs into the keyhole,

c. rotating the bayonet connector about its longitudinal axis within the first opening and the keyhole and

d. retaining, the first and the second component between the head and the thread webs of the bayonet connector.

9. The connection method according to claim 8 with the further step:

providing the first component with the first opening, in which the bayonet connector is pre-positioned via a pre-positioning web at the head of the bayonet connector, or

providing the first component with the first opening and the bayonet connector separate from each other and plugging the bayonet connector into the first opening in the stack-like arrangement out of the first and the second component.

10. The connection method according to claim 8 , in which each fastening means of the two thread webs includes a locking projection facing the head, which, when rotating the bayonet connector each lock into a recess or an opening at the second component.

11. The connection method according to claim 8 , in which the thread webs include ramp slopes facing the head, which, when rotating the bayonet connector about its longitudinal axis clamp the first and the second component between the head and the thread webs of the bayonet connector.

12. The connection method according to claim 8 with the further step:

before plugging the central shaft with the two thread webs into the keyhole searching of the keyhole with the finder tip of the central shaft and aligning the bayonet connector for screwing in.

13. The connection method according to claim 8 , with the further step:

when rotating the bayonet connector, screwing in the thread webs into the keyhole and drawing together the first and the second component via a screw connection between the thread webs and the keyhole.
