Description

The invention relates to a multipolar, in particular three-pole, electrical connector system.

Such connector systems are used in particular in the industrial and commercial electrical installation area to the electrical supply network, for. an office, shop or exhibition stand on the basis of plug-in connections simple, fast and flexible to implement. Connector systems often consist in the manner of a modular system of a variety of combinable modules for the electrical connection of free lines, realization of electrical network nodes or branch points, for connecting a supply line to an electrical device, or the like. Each module comprises at least one plug part or a complementary to this socket part, via which the module can be combined with another module for the realization of the connector.

Such a connector system is known, for example, from EP 0 471 943 A1.

A connector system is subject to a variety of partly conflicting requirements in terms of its practicality. In particular, the connector system should have a high degree of prefabrication in the sense of a rational production, ie enable comparatively few individual parts to realize as many modules as possible for different purposes. It should be easy and safe to install at the same time. Trained by means of the connector system connectors should continue to be secured against unintentional or unauthorized release of the connector, the installer on the other hand, however, allow an unobtrusive release of the connector. The latter is particularly important in order to be able to quickly dismantle trade fair stands and other mobile installations.

The object of the invention is to provide a multipole electrical connector system that is particularly suitable, particularly flexible and that can be produced efficiently, against the background of the above-mentioned requirements.

This object is solved independently by the features of claims 1 and 9.

According to claim 1, the connector system according to the invention comprises a socket part and a corresponding plug part and a mounting frame which is adapted to receive the socket part or the plug part and to support in a mounting opening of a wall, that the plug or book part of an outer side of the wall is accessible to the formation of a plug connection. The wall is in particular the housing wall of an electrical device. The plug or socket module thus forms with the mounting frame, in which it is received, a device connection module, via which an electrical supply line to the device can be connected. The connector system according to the invention further comprises locking means which releasably lock the socket part with the plug part in the assembled position, wherein the mounting frame is provided with an opening aid, by which the latching means can be unlocked under the action of an actuating force directed from the outside through the mounting opening.

The invention is based on the recognition that in a connector system of the type mentioned above, a mounting frame of the above type to achieve a high degree of prefabrication is advantageous, especially since the plug part or socket part with which the mounting frame can be fitted, even without the latter as part of a free Ladder connection is used. It was recognized, however, when using the male or female part in the mounting frame for Securing the connector provided locking means are completely or partially covered by the mounting frame, so that these locking means would no longer or only with difficulty be accessible for unlocking. By provided on the mounting frame opening aid this problem is overcome. Characterized in that the opening aid is designed such that it allows unlocking of the latching means by an externally acting actuating force, it is achieved that in the mounting position of the device connection, in which the mounting frame with the plug or socket part received therein in a housing wall of a device is fastened, the locking means can be unlocked without opening of the device even if the male or female part, and thus in particular the locking means, are arranged inside the device.

In a preferred embodiment, the latching means comprise a latching hook and a corresponding latching opening, wherein the latching hook are mounted on the plug or socket part, and the latching opening on the other part such that in the assembled state of the socket part with the plug part of the latching hook in the latching opening is locked. In order to enable a simple unlocking of the locking means, the latching opening is in this case open to the outside of the other part, so that is accessible to solve the latching connection of the latching hook through the latching opening therethrough.

As manufacturing technically easy to implement and easy to handle, an opening aid has been found in the form of a reversing lever. The lever is formed on the mounting frame, that it is accessible through a guide channel of the mounting frame for an actuating force exercising actuating tool, in particular a screwdriver and under the action of the actuating force is deflected so that he, when the female part and the plug part in zusammengestecktem state are held in the mounting frame, the locking means unlocked.

Due to the design of the mounting frame, the socket part and the plug part as optional and interchangeable parts can be combined with one another achieved particularly high degree of prefabrication of the connector system. In terms of a particularly simple assembly, the socket part or plug part can be advantageously fixed by a snap connection to the mounting frame.

In order to realize a space-saving and safe device connection, the female part or plug part is preferably fixable in the mounting frame, that the female part or plug part with a mating side, approximately flush with an outer side of the mounting frame, and thus in the assembled position completely or at least largely in Device interior is arranged. In this case, the "side" of the plug part or socket part is designated as "plug-in side", to which the respective corresponding part is intentionally coupled for the purpose of realizing the plug connection.

A preferred embodiment of the mounting frame, in which this on an outer side a support collar for support on the edge of the mounting hole, and the support collar opposite a number of spring arms for clamping the mounting frame in the mounting hole, is for a simple and mechanically stable attachment of the mounting frame in a mounting opening of the wall advantageous.

According to claim 9, the connector system according to the invention comprises a socket part and a corresponding plug part and a first housing half and a second housing half. The housing halves are in this case fastened to the socket part or to the plug part in such a way that they complement one another to form a substantially closed insulating housing which surrounds a conductor connection side of the socket part or plug part. In this case, at least one of the housing halves has an axle-like joint projection, with which the housing half can be snapped into a corresponding joint receptacle of the socket part or plug part, so that the housing half is reversible relative to the socket part or plug part in an open position in which the housing half the conductor connection side of the socket part or plug parts releases, and in a closed position in which the housing half surrounds the conductor connection side of the female part or plug part, is pivotable.

Preferably, the plug part, the female part, the mounting frame and the two housing halves are formed as components of the same modular connector system, so that selectively and against each other interchangeable plug part or the female part both used in the mounting frame and can be combined with the housing halves to a free Leiterabschluss.

Figures 1 to 3 show in perspective individual parts of a multi-pin connector system 1. The illustrated connector system 1 is designed in three poles. However, within the framework of the design principle described, modifications are also provided with deviations in the number of poles, in particular with two or five poles. The connector system shown serves in particular a simplified structure of electrical supply networks in industrial, commercial and building installation area, in particular for the realization of a room lighting system, the power supply of a booth or the like.

The connector system 1 comprises according to FIG. 1, a female part 2 made of an insulating material, in particular plastic. The female part 2 has guide channels 3 for receiving one connecting element 4 each. Each connection element 4 is provided with a socket contact 5 facing in the installed position of a plug-in side 6 of the socket part 2. Opposite to the socket contact 5, the connecting element 4 carries a clamping contact 7, which faces in the installed position of a conductor connection side 8 of the female part 2 and to which an electrical conductor is klemmkontaktierbar under actuation of a corresponding clamping screw 9.

The female part 2 is provided with three molded and projecting to the mating side 6 protective sleeves 10, each of which surrounds the female contact 5 of the associated connection element 4 safe from contact. The protective sleeves 10 are encoded by appropriate unbalanced shape such that only one with the female part 2 uniquely corresponding male part in a unique position contacting the protective sleeves 10 can be pushed. The principle of such coding is disclosed per se in EP 0 471 943 A1.

At a small distance from the protective sleeves 10, a latching hook 11 is integrally formed on the mating side 6 of the female part 2, which projects freely parallel to the protective sleeves 10 to the mating side 6 and for releasable locking of the female part 2 with a corresponding connector part 12 (FIG. 2). serves.

In Fig. 1 also shown two housing halves 15 and 16, which can be attached to the female part 2 and can be combined to a the conductor connection side 8 of the female part 2 and thus an optionally realized there conductor connection against contact, damage, etc. protective housing.

Each housing half 15, 16 has at an insertion end on an axis-like hinge projection 17. Each hinge projection 17 can be snapped into a corresponding joint receptacle 18 of the socket part 2, so that the corresponding Housing half 15 and 16 is pivotally fixed to the socket part 2. As a result, the housing halves 15 and 16 can be pivoted into a folded-open position (into a position shown in more detail in FIG. 6), in which the conductor connection side 8 of the socket part 2 is freely accessible for connection to an electrical line. After the line has been connected, the housing halves 15 and 16 can then be pivoted into a closed position (shown in more detail in FIG. 5), in which the housing halves 15 and 16 are combined together with the socket part 2 to form a closed housing.

The illustrated in Fig. 2, corresponding to the female part 2 plug part 12 receives three connection elements 20. Each connection element 20 is provided with a pin contact 21, which faces in the installed position of a plug-in side 22 of the plug part 12. The pin contact 21 respectively opposite end of each connection element 20 is provided with a (corresponding to the clamping contact 7) terminal contact 23. Each clamping contact 23 is in turn actuated by a clamping screw 24. The protruding in the installed position on the plug-in side 22 from the plug part 12 pin contacts 21 are surrounded by a plug side 22 toward open protective frame 25 which is integrally molded to the plug part 12 and acts as a contact protection against contact of the pin contacts 21.

When plugging the connector part 12 on the corresponding female part 2 surrounds (as can be seen in particular in Figs. 7 and 8), the protective frame 25, the protective sleeves 10 of the female part 2. In order to cooperate with the shape coding of the protective sleeves 10, the mating of the female part 2 with the Plug part 12 allow only in a unique position, the protective frame 25 is also provided with a corresponding shape coding.

The protective frame 25 is further provided with a detent opening 26 which serves as a repository for the latching hook 11 of the female part 2. The detent opening 26 is in this case accessible from the outside to the latching hook 11 by means of a suitable tool, in particular a screwdriver, to solve the male part 12 deflect from the socket part 2 inwards and thereby unlock it.

The plug part 12 is like the socket part 2 provided with joint receptacles 18, so that the housing halves 15 and 16 are fastened to the socket part 2 as well as to the plug part 12 as well.

In combination with a pair of housing halves 15 and 16, the female part 2 and the plug part 12 form a touch-safe conductor termination. A with each corresponding housing halves 15 and 16 provided and mated plug-socket pair is shown in Fig. 7. By means of such a plug and socket pair, in particular two free electrical lines can be contacted easily and safely electrically.

At the housing halves 15 and 16 in this case a particularly simple and quick to use and effective train protection is formed for a line end. The design and function of this strain relief can be seen in particular in a combined view of Figures 1, 4 and 5. The strain relief comprises an arc-shaped contour which is referred to below as a half clamp 30 and which is integrally formed on the side of the housing half 16 facing away from the joint projection 17 in the interior of the same. At each transverse end of the half clamp 30 in this case a threaded hole 31 for receiving a clamping screw 32 is arranged.

A corresponding with the half clamp 30 second half clamp 35 is initially integrally integrated in the housing half 15. The half clamp 35 is in the form of a tab which has two passages 36 for receiving a respective clamping screw 32 and which is connected to the housing half 15 only via four discrete injection points 37 (FIGS. 8 and 9). The injection points 37 are each mounted on each side of each bushing 36 and dimensioned so weak in terms of their material thickness that they act as predetermined breaking points.

To actuate the strain relief is after connection of a conductor to the female part 2 and the plug part 12, the associated with this housing halves 15 and 16 folded into the closed position. After locking the housing halves 15 and 16, the clamping screws 32 are screwed into the corresponding threaded holes 31, whereby the half-clamps 30 and 35 close yoke to the connected line and clamp them between them , By tightening the clamping screws 32, the half clamp 35 is increasingly braced relative to the housing half 15 until the injection points 37 break as intended. The half clamp 35 is now mechanically decoupled from the housing half 15, so that the housing halves 15 and 16 can be unfolded without affecting the strain relief.

As an alternative to the housing halves 15 and 16, a mounting frame 40 shown in FIG. 3 can be connected to the socket part 2 or the plug part 12. The mounting frame 40 serves for substantially flush mounting of the socket part 2 or plug part 12 on a mounting opening formed in a wall 41, so that the socket part 2 or plug part 12 from the wall outside by the respective corresponding part 2 or 12 can be contacted. The wall 41 is, for example, the wall of a device housing or a fairing.

The mounting frame 40 is provided with a support collar 42, by means of which the mounting frame 40 is supported in the assembled position on the outside of the wall 41 on the edge of the mounting hole. The mounting frame 40 further comprises four spring arms 43, which are adapted to spread from the inside against the wall 41 and thus to fix the mounting frame 40 in the mounting opening.

For fastening the socket part 2 or plug part 12 to the mounting frame 40, the latter comprises two latching hooks 44 and three fork-like latching elements (hereinafter referred to as locking forks 45). If the socket part 2 or the plug part 12 is pushed onto the mounting frame 40 (as shown in FIGS. 9 and 10), the latching hooks 44 engage in corresponding slots 46 which are provided on both sides of the latching hook 11 or the latching opening 26 on the socket part 2 or Plug part 12 are formed, and lock behind it. As a reversion for each latching fork 45 is a mushroom-like projection 48 is provided on a bottom 47 (Fig. 10) of the female part 2 and male part 3, the stem is embraced by the respective corresponding locking fork 45 form fit.

The projections 48 serve simultaneously as a connection mark. Each projection 48 corresponds in this case to a corresponding housing opening 49 (FIG. 1), which the respective projection 48 passes through when the housing is closed in such a way that it terminates approximately flush with the housing wall. In this way, it is achieved in a particularly simple and expedient manner that a marking mounted on the projection 48 is visible both when the housing is open and when the housing is closed.

In order to enable easy unlocking of the socket part 2 and the plug part 12 even when the socket part 2 or the plug part 12 is used in combination with the mounting frame 40, an opening aid 50 is provided on the mounting frame 40. By this opening aid 50 in particular the problem is solved that the latching opening 26 is generally not or only very difficult to access when the connector system 1 is used together with the mounting frame 40, in particular when the socket part 2 and the plug part 12 in the area Wall 41 are coupled.

The opening aid 50 comprises a deflection lever 51, which is formed on the support collar 42 of the mounting frame 40 and from there to the inside, that projects away from the support collar 42. The reversing lever 51 is formed substantially L-shaped or T-shaped and ends freiendseitig in a stop plate 52 which acts as an abutment for a release tool, in particular a screwdriver 52. To operate the opening aid 50 is the screwdriver 52, as shown in FIGS. 11 and 12, from the outside, ie by the support collar 42 of the mounting frame 40 and optionally through the wall 41, attached. For a secure guidance of the screwdriver 52, the mounting frame 40 has a corresponding guide channel 53, which opens in the region of the support collar 42. The tip of the introduced into the guide channel 53 screwdriver 52 abuts the stop plate 52 of the reversing lever 51 as intended, so that when pressure is exerted on the screwdriver 53 of the lever 51 is deflected according to the registered in Fig. 12 direction portion 55 downward. In this case, the deflection lever 51 abuts against the latching hook 11, which in turn is unlocked.

The integration of the opening aid 50 on the mounting frame 40 has the particular advantage that the opening aid 50 functions independently of whether the mounting frame 40 is connected to the socket part 2 or the plug part 12. By the guide channel 53 in this case a defined force acting direction is enforced, which allow a safe and easy unlocking of the plug part 12 of the female part 2 even in confined spaces.

The integration of the opening aid 50 on the mounting frame 40 has the particular advantage that the opening aid 50 functions independently of whether the mounting frame 40 is connected to the socket part 2 or the plug part 12.

13 and 14 show modified embodiments of the connector system 1. Thus, as shown in FIG. 13, the latching hook 11 of the female part 2, deviating from the illustration of FIG. 5, provided with a longitudinal slot 56. This longitudinal slot 56 corresponds to a spring tab or rib which is mounted in the region of the latching opening 26 on the protective frame 25 of the plug part 12 such that upon mating of plug and socket part 12, and 2, the spring tab is lifted by the latching hook and with the pivoting of the latching hook 11 engages in the latching opening 26 at the same time in the longitudinal slot 56 of the latching hook 11. In this embodiment, the tensile strength of the connector is improved. Referring to FIG. 14, instead of the three shown in FIG Resting forks 48 two locking arms 57 are provided, each with a closed recess or bore a corresponding projection 48 of the female part 2 or plug part 12 form-fitting enclose, when this part 2 or 12 is inserted into the mounting frame 40. This variation of the mounting frame 40 serves for improved retention of the socket part 2 or plug part 12 in the mounting frame 40.
