A resilient strip (4), deformable by the pin, is arranged in the mouth region of the hook which cooperates with the pin. The strip is pref. formed integrally with the mouth of the hook. It is pref. convex and attached in the region of a limb (11) of the hook at the base of the mouth. Pref. the end of the hook distal from the mouth is rotatable and can be locked in different rotational positions and is located on a mounting block (2) by a locating pin (15). ADVANTAGE - Enables simpler and more logical handling esp. for unlocking.

Description

The present invention relates to a device for releasable locking of connector parts, cable strain relief or the like according to the generic term of claim 1.

Such a device is known from European patent application 03 34 973 device known in the example of two nested connectors derteile is interlocked by the fact that on a connector partially formed transverse to the direction of insertion elastically spread as wings Locking elements are provided which have locking holes in the locking pin the other connector part.

Basically, this type of locking has proven itself.

However, regarding the handling when loosening the connector tion, i.e. problems arise when pulling the two connector parts apart ben, since practically both locking elements are spread as far at the same time must be released.

Since both hands are usually required to spread the locking elements, must pull out the corresponding connector at the same time another person, which naturally ent optimal handling ent opposed.

The present invention is therefore based on the object, a Vorrich tion of the generic type to create the simpler and more rational Handling, especially when unlatching allows.

This object is achieved by the in the characterizing part of Features mentioned claim 1 solved.

Contrary to the known device, each locking element now comes through a pivoting in the longitudinal direction of the connector is engaged or is released from the locked position.

Because when using two locking elements each can be pivoted individually can be unlocked very easily.

According to an advantageous embodiment of the invention, the rest hook in disengaged position by appropriate locking means in ver different positions are locked, which means the handling of the device even more relieved.

The locking spring strip is expediently convex and on the one hand firmly on the mouth of the hook leg and on the other hand in the area of the mouth opening placed.

When the locking hook is swung over the locking pin, the locking spring last elastically deformed until the locking pin on the base of the mouth has reached its final position.

In a manner known per se, the locking hook on a mounting bracket gela gert, which in turn is connected on the one hand to a connector part can be and on the other hand to be attached to a mounting rail.  

The use of the device is not limited to the locking of Connector parts, but makes sense wherever parts on which u. U. relatively large forces act so that they should be fixed can be easily removed from this fixed position.

For example, such a device can also be used for cable strain relief are used, which are to be held in a certain position, whereby then the mounting brackets on both sides of the cable strain reliefs the locking hooks are pivotally fixed, firmly connected to mounting rails will.

Further advantageous embodiments of the invention are in the subclaims Chen marked.

An embodiment of the invention is described below with reference to the beige added drawings.

Show it:

Fig. 1 shows a device according to the invention in perspective view,

Fig. 2 shows the device in the use position in a side view;

Fig. 3 is a plan view of the device according to FIG. 2.

In the figures, a device for releasably latching Steckverbin derteile or, as shown in FIGS . 2 and 3, of Kabelzugentlastun conditions 16 is shown.

The device consists of a locking element which is designed as a pivotable locking hook 1 , which cooperates with a locking pin 15 which is connected to the part to be held, in the present case the cable strain relief 16 .

In the mouth region of the latching hook 1, in which the locking pin 15 rests in use Stel lung, a detent spring bar 4 is arranged, which is deformed at about pivoting of the latching hook 1 to the locking pin 15 therethrough.

In the position of use shown in FIG. 2, the detent spring bar 4 holds the detent pin 15 practically on the base of the mouth. The locking spring strip 4 is convex in shape and fixed to a hook leg 11 of the locking hook 1 in the area of the jaw base.

A provided with a foot part 10 , by means of which it can be firmly placed on a mounting rail 17 , mounting bracket 2 has a molded Lagerzap fen 12 .

On this, the locking hook 1 is pivotally mounted in the position of use, the locking hook 1 having a bearing opening 5 through which the Lagerzap fen 12 is guided.

On the end face of the journal 12 there are three teeth 9 projecting radially outwards, two of which are at the same angle to the third, while these two are at an angle to one another which is different from the other two angles.

The locking hook 1 has in the region of its bearing opening 5 corresponding teeth 9 adapted tooth openings 6 , so that it in a certain Stel development, in which it projects in the direction of the foot part 10 , pin 12 can be plugged onto the bearing.

In principle, the teeth 9 and the tooth openings 6 represent a code, since the latching hook 1 can only be plugged onto the bearing pin 12 in one position. Due to the described angular arrangement of the teeth 9 and the Zahnöffnun gene 6 there is the possibility to use the locking hook on the left and right side.

To the latching hook 1 to keep in non-use position into a locked position, being prevented by the remaining hook 1 Untitled uninten detached from the journal 12, are both provided on the mounting bracket 2 and also on the latching hook 1 locking means.

In the present embodiment, the latching hook 1 in correspondingly extending from its outer contour, extending on both sides of circumferential ribs 7, through which the bearing hole 5 protrude on both sides in the rest area having exist. The mounting bracket 2 is provided with the associated web 7 corresponding slots 13 , 14 , corresponding to the respective locking position of the web 7 engages in one of the slots 13 , 14 .

Since both the mounting bracket 2 and the locking hook 1 are usually made of a plastic, due to the inherent elasticity of the locking hook 1 it can be released from the locking device and pivoted into the required position.

For better handling, the locking hook 1 is also provided with a corrugation 18 at a suitable point.

The foot part is screwed to a clamping jaw 19 , which engages behind a mounting rail 17 and fixes the mounting bracket 2 together with the connected latching hook 1 on the mounting rail 17 .
