Definitions
- the invention is based on a device for shaking-resistant locking of a plug in its plug-in position within a device, in particular within a coupling actuator, with a housing having at least two housing shells according to the preamble of claim 1.
- a known clutch actuator for engaging and disengaging a vehicle clutch according to DE 197 01 739 AI is integrated in a double-shell housing, which consists of a lower housing shell and an upper housing shell, which can be pivoted relative to one another about a pivot axis, so that two flanges formed on each housing shell underneath Lay a gasket between each other.
- An electric motor for driving a tappet which is connected to a piston of a hydraulic master cylinder, is accommodated in the lower housing shell.
- electrical plug connections are necessary, which are realized, for example, by plugs arranged at the end of power cables, which are plugged into assigned sockets or slots on the electric motor.
- the device according to the invention for shake-proof locking of a plug in its plug-in position with the characterizing features of claim 1 has the advantage that further assembly of the device is ruled out if the plug is not in its final plug-in position, so that it is always correct Assembly of the connector is guaranteed. In addition, no additional parts are required, since the locking function is performed by the locking section of the locking element, which is present anyway.
- a particularly preferred development of the invention provides that a section of the plug is flush with an assigned section of the locking element and the locking element relative to the housing is locked into a locking position only when the plug has reached the fully inserted position.
- Position is movable, in which the portion of the plug is overlapped by the associated portion of the locking element to hold the plug in the plug position. Since locking is only possible with the correct plug position, incorrect plug positions of the plug are immediately apparent.
- the locking element is held in the locking position by the housing top shell fitted onto the housing bottom shell. Since the mounted upper housing shell prevents unlocking, the locking of the plug is self-locking and cannot be unintentionally released, which is an advantage particularly in the case of plug connections which are subjected to vibrations.
- the locking section also serves as a gripping section for actuating the locking element and has a flat shape. This results in an advantageous, because space-saving, functional combination is realized.
- Figure 1 is a plan view of a lower housing shell of a clutch actuator, in which an embodiment of an inventive device for shake-proof locking of a connector is integrated.
- Fig. 2 is an enlarged sectional view taken along the line II-II of Fig.l; 3 shows a cross-sectional view through the clutch actuator from FIG. 1, the device according to the invention being in an unlocked position;
- FIG. 4 shows a cross-sectional view through the clutch actuator of FIG. 1, the device according to the invention being in a locked position;
- the clutch actuator 1 for engaging and disengaging a vehicle clutch, an embodiment of a device 2 for shake-proof locking of a connector 3 is integrated in its inserted position.
- the clutch actuator 1 consists of a two-shell housing 4, of which only a lower housing shell 6 is shown in plan view in FIG. 1, in which an electric motor 8 with a crank mechanism 10 and a tappet 12 are received, which is connected to a hydraulic master cylinder 14.
- An outer flange 18 is formed on the lower housing shell 6 and the upper housing shell 16 shown in cross section in FIGS. 3 and 4, on which eyes 20 are formed with through bores or threaded bores around the two housing shells 6, 16 with a seal interposed to be able to screw.
- the function of such a clutch actuator 1 is e.g. from DE 197 01 739 AI well known, therefore no further explanations are given.
- a terminal strip 22 with slots is attached to it, onto which connectors 26 attached to the ends of the electrical lines 24 are attached (FIG. 1).
- a linear guide 28 locking element which in a preferred embodiment is a slide 30.
- the linear guide 28 of the slide 30 is realized in that, from a wall 32 of the lower housing shell 6, a pin 34 arranged adjacent to the connecting strip 22 projects vertically, for example, which engages in an elongated hole 36 of a guide section 38 of the slide 30, whereby the slide 30 becomes the plug 3 is occasionally movable away from it, preferably in a direction transverse to it.
- the pin 34 is held in the elongated hole 36 of the slider 30 by a spring washer 40 pressed on from the outside, as can best be seen from the enlarged cross-sectional view in FIG.
- FIG. 3 shows a broken, lateral cross-sectional view of the clutch actuator 1 in an assembled state before the two housing shells 6, 16 are joined, the plug 3 not being fully inserted into its assigned slot 22.
- FIG. 1 shows it in the correctly assembled state after joining the two housing shells 6, 16.
- the connector 3 is preferably on the head side with a
- the underside facing away from a bottom of the housing lower shell 6 represents, for example, a horizontal counter surface 44 for a hold-down surface 46 on the underside of the guide section 38 of the slider 30, with which it runs along a guide surface 48 formed on the housing lower shell 6 can slide.
- the guide surface 48 for the slide 30 preferably lies in one plane with the hold-down surface 46 of the slide 30.
- the plug 3 stood according to FIG. 4 the surface of the tongue 42 facing the bottom of the lower housing shell 6 rests on a stop surface 50 of the lower housing shell 6.
- the hold-down surface 46 on the slide 30 is only flush or coplanar with the counter surface 44 of the plug 3 when it is fully inserted (FIG. 4). Only in this case can the slider 30 be moved in the direction of the plug 3 and the hold-down surface 46 of the slider 30 overlap the counter surface 44 of the plug 3 in order to fix it to the terminal block 22.
- a flat gripping section 52 is formed on the guide section 38 of the slider 30 on the side facing away from the plug 3 in order to move the slider 30 by hand from the position shown in FIG. 3, in which the plug 3 is unlocked, into which the plug 3 to push the locking position according to Fig. 4. If, however, the plug 3 according to FIG. 3 is not inserted completely or in a tilted position into the assigned slot of the terminal block 22, the underside of its tongue 42 is spaced apart from the stop surface 50, as a result of which the tongue 42 of the plug 3 is the guide surface 48 for the slide 30 protrudes a bit and consequently prevents the slide 30 from moving in the direction of the plug 3.
- a lower edge 54 of the gripping section 52 of the slide 30 pointing towards the bottom of the lower housing shell 6 projects beyond the outer flange 18 of the lower housing shell 6 regardless of whether the locking position has been assumed or not.
- the projecting length of the gripping section 52, the relative position and the length of the elongated hole 36 of the slider 30 are selected such that the gripping section 52 laterally over the plug 3 in the unlocked or unlocked state formed by the outer flange 18 outer contour of the lower housing shell 6 also protrudes, so that in this case joining the two housing shells 6, 16 is impossible.
- the gripping section 52 also serves as a blocking section in order to prevent further assembly of the clutch actuator 1 when the plug 3 is not fully inserted into the slot 22.
- the hold-down surface 46 of the slider 30 can overlap the then counter-planar counter surface 44 of the plug 3 and the slider 30 can move into the locking position.
- the displacement of the slider 30 is determined, inter alia, by the length and the relative position of the elongated hole 36, these parameters being selected such that, when the slider 30 is in the locked position, its end face 56 preferably contacts a side face 58 of the plug 3 and the locking section 52 no longer covers the outer flange 18 of the lower housing shell 6.
- the locking section 52 is located within the circumferential line of the clutch actuator 1 specified by the outer contour. Relative to its vertical extent, an upper edge 60 of the locking section 52 is located below an upper wall 62 of the upper housing shell 16, so that the latter is open can add the lower housing shell 6.
- the housing upper shell 16 prevents the slide 30 from being released from the locked position by the distance between the free end 64 of the locking section 52 of the slide 30 and a side wall 66 of the upper housing shell 16 being less than the displacement path required for unlocking. In this way there is a self-locking lock of the plug 3, unlocking can only take place after dismantling the housing shells 6, 16.
- the device 2 according to the invention is not limited to the locking of a single plug 3, rather a plurality of plugs 26 can be locked by widening the slider 30 or by using a plurality of sliders 30.
