In the Figures 1 - 3 is the reference numeral 1 a total of a connector which is not part of the invention is referred to, which consists of a first connector part 2 and a second connector part 3, wherein the two connector parts 2 and 3 can be secured by locking slide 4 in the coupled state against unintentional release.

In the illustrated embodiment, it is at the first connector part 2 to a so-called socket and the second connector part 3 to a so-called plug or pin part, in which case the first connector part 2, ie the socket part, a guide housing 5 with a guide channel 5a Recording and sliding guide of only one locking slide 4 are formed.

In the second connector part 3, ie in the pin part, are still to be described constructive measures taken to fix the relative to the connector part 2 movable locking slide 4 in a locking position can. These measures include an insertion channel or guide channel 10 for the locking slide 4. It should be expressly noted at this point that here, of course, a reversal is possible, d. h., That the locking slide 4 is guided in corresponding guide channels of the pin member 3 and the socket part 2 has corresponding configurations for the locking of the locking slide 4.

The connector is designed as a printed circuit board connector for contacting a printed circuit board 25.

For this purpose, a connector part 3 is arranged on the printed circuit board 25. It has four arranged in a row pin contacts 26 which are designed to be angled with one of its ends soldered to the circuit board 25, where they contact tracks, and with its other end a part of the mating contacts of the mating face of the second connector part 3 Form coupling with the mating face of the other connector part 2.

On the first connector part 2, however, socket contacts (not visible here) are arranged, which contact the contacts 26 of the second connector part 3 in the assembled state and which are provided with terminals 27, here by way of example screw, for connecting outgoing conductor (not shown here). Also, the terminals 27 are arranged in a row.

The connector parts each have a housing 28, 29, wherein the only one (shown and preferred) or the two or more (not shown) locks - especially the locking slide 4 and the corresponding guide channel 5 - not laterally outside next to the row of the coupling contacts is / are arranged but in the row between each two of the contacts to be coupled together of the two connector parts 26 and 27th

This arrangement will be particularly good from the Fig. 1a and 1b clear. Here is the number of contacts to be joined together the mating faces of the two connector parts 2, 3 straight. It is four by way of example. In this case, it makes sense to arrange the lock with its elements 4 and 5 centrally in the row of contacts from the contacts 26, so that on both sides towards the same - here two - the contacts are arranged.

In this case, the number of locks or the locking slide 4 and guide channels 5a, 10 can be reduced to only a single one of these elements, since the lock is arranged optimized so that it optimally absorbs forces that can act on the connector ,

This is not part of the invention. It is optimized by the invention.

According to this invention, further functional elements are arranged in the region of the locking.

With regard to the measure to associate the locking slide further functional elements, it should be noted that a locking of the two connector parts 2 and 3 relative to each other may optionally be performed with two or more locking slides 4. In this case, only one or more or all or all locking slides can be assigned to these further functional elements, in particular contacts. However, this further embodiment can also be applied if two locking slides are arranged laterally next to the row of contacts to be connected to the connector parts.

In the Figures 1-3 is denoted by the reference numeral 6, the coupling plane between the two connector parts 2 and 3 and their mating faces.

As can be clearly seen from the drawings, the guide channels 5a and 10 run perpendicular to the said coupling plane 6, so that correspondingly the locking slide or slides 4 are displaceable perpendicular to the coupling plane 6.

Each locking slide 4 is provided at its end facing the second connector part 3 with a provided with a locking cam 7, resilient tongue 8. The locking projection 7 is seen to the free end face of the tongue 8 with an obliquely sloping inlet bevel 9.

The resilient tongue 8 with the locking cam 7 is the insertion channel 10 of the second connector part 3 opposite, through which the locking cam 7 and a part of the resilient tongue 8 for the purpose of locking the two connector parts 2 and 3 in the second connector part 3 can be inserted until the Latching cams 7, the guide channel 5 end surrounding the end face 11 engages behind. This position is clear Figure 1d ,

The resilient tongue 8 is formed on an actuating bracket 12 of the locking slide 4, wherein the actuating bracket 12 is outside the respective guide channel 5 of the first connector part 2 and is provided for ease of operation on its side facing away from the guide channel 5 top, for example, with ribs 13. As an alternative to these ribs, other means for improving the operation may also be provided here, for example molded knobs or the like.

By pressing the operating bar 12, the resilient tongue 8 can be pressed with the locking cam 7 so far down that the locking cam 7 is brought out of its locking position out into a position in accordance with a pushing back of the locking slide 4 in the release position Figure 1c allows this backward displacement is carried out by simultaneous pressure on the actuating bracket 12, as well as a shift. By shifting back then the complete locking slide 4 can again in its release position according to Figure 1c to be brought.

In the locked state, at least one stop cam 17 adjacent to the actuating bow 12 and located at the end of the locking slide 4 facing away from the coupling plane 6 bears against the boundary wall 16.

In this case, the displacement of the locking slide 4 is determined by the length of the boundary wall 16, abut the alternately the bracket portion 12a and the stop cam 17.

The locking slide 4 may expediently be provided in the region opposite the boundary wall 16 with a stop cam 17, which then abuts in the locked state on one of the boundary wall 16 opposite side wall 18 of the guide housing 5.

In the locked state, the locking slide 4 preferably ends flush with the end faces of the guide housing 5.

In its central region of the locking slide 4 is preferably provided with a running in the direction of displacement through hole 20.

This through-hole 20 can be used for an optional locking screw or alternatively here for another electrical functional element such as a contact 21, which contacts another functional element such as a mating contact 22 on the other connector part when pushing together or plugging the two connector parts.

The contacts 21, 22 may be formed as a female contact and as a pin contact or as hermaphrodites contact pair not shown here, of which the female contact exemplifies the contact 21 and the pin contact exemplifies the mating contact 22 on the other connector part ( Fig. 1 )

The functional elements may also be the elements 23, 24 of a reed contact, consisting of magnetically actuated contacts, for example, on the circuit board or in the space of a flange and a permanent magnet in the movable part of the locking device or vice versa ( Fig. 2 ).

Alternatively, it is also conceivable to use as a functional element a plunger on the locking slide 4 or the locking slide itself as a plunger to two contacts such as sheets or pins 14, 15 close to the corresponding connector part 3 ( Fig. 3 )

The locking slide has the advantage that the locking state is visually recognizable from the position of the locking slide 4.

The other functional elements, which are integrated in the lock, in particular also allow electrical monitoring of the locking function by a higher-level control and monitoring system. It is also conceivable to change the state visually or acoustically, e.g. with a LED directly on the connector. It is advantageous that may be waived by the other contacts, if necessary, to separate further cable connections, since the connector further integrated contacts, e.g. for control purposes.

It is also conceivable, e.g. by using a plurality of at least one contact chamber with at least two electrically separate auxiliary contacts to use the at least one or the other (auxiliary) contacts for other purposes, such as control contacts or as contacts for a data or supply line, for. a bus, which also includes the other to be connected to the connector parts (if necessary, further connections to the circuit board or to the outside are formed on the connector parts, which can be designed in any technique such as push-in or the like.).

The locking slide 4 is here exemplified in one piece from a resilient material, preferably made of plastic.

To Fig. 4 is denoted by the reference numeral 1 turn the connector, which consists of the first connector part 2 and the second connector part 3, wherein the two connector parts 2 and 3 can be secured by a locking device 4 in the coupled state against unintentional release.

The locking device 4 of Fig. 4 also secures in a locked position ( Fig. 4c ) the two interconnected connector parts 2, 3 against unintentional release and is movable in a holding device of the second connector part 3. The holding device is designed as a latching edge 30 in the insertion channel 10. The locking device 4 is preferably displaceable relative to this connector part 2 on the first connector part preferably between two of the contacts but arranged pivotably on this connector part. In turn, it has a tongue 8, at the free end of a latching hook or locking cam 7 is formed, which in turn preferably also has an inlet slope 9.

The tongue 8 is further connected in a spaced-apart from the latching hook region via a web 31 with the second connector part 2. To the tongue 8, an actuating bracket 12 is further formed, which is configured and arranged so that by pressing the operating bar 12 perpendicular to the insertion direction X, the tongue 8 with the latching hook / cam 7 is substantially perpendicular to the insertion direction X movable or pivotable ,

When pushing together the two connector parts 2, 3 ( Fig. 4a ) the inlet bevel 9 first touches the latching edge 30, as a result of which the tongue 8 is deflected ( Fig. 4d ), until the locking cam 7, the latching edge 30 finally engages latching further pushing the two connector parts 2, 3. In this position, the two connector parts 2, 3 are secured against unintentional pulling apart ( Fig. 4c ).

By pressure on the operating bar 12 can (corresponding to Fig. 4b ) the tongue 8 with the locking cam 7 are pivoted out of the locking position, so that the two connector parts 2, 3 can be pulled apart again.

The other optional functions of the preceding figures can also be realized in this embodiment.
