Description

The invention relates to a socket with a socket housing, in which an insertion opening for insertion of a plug is formed in the socket and having a hinged at the socket lid, can be covered by the insertion. The hinging of the lid can be done on the socket housing, inserted into the socket housing contact carrier insert or any other fixable on the socket component. As a result of this articulation, the axis of rotation of the lid is at least fixed relative to the insertion. Furthermore, the socket has a locking mechanism with which the plugged into the socket lid in the socket is releasably locked. The socket is provided in particular for the electrical connection of a towing vehicle with a trailer and can due to the lock, which after the Standard ISO 11783-2 may be formed, in particular be designed for the connection of a tractor with an agricultural machine or also for the electrical connection of trucks and their trailers use. Especially in agriculture or construction used additional control devices increasingly require signals that are transmitted via a CAN bus connection between the agricultural machine and the tractor or tractor and trailer or construction equipment.

Especially are known for use in these areas sockets that the lock the inserted plug into the socket using a bayonet ring and so set the electrical connector between Socket and plug even in the tough conditions in safely guaranteed for agriculture or construction machinery becomes. However, the sockets with the bayonet lock are complex and in the case of agriculture or agriculture under construction regularly occurring pollution of the socket the connector is often not easy to solve. Furthermore, there are hardly any socket systems with bayonet locking known, which enable a CAN bus connection.

From the EP 1 492 203 A2 a generic socket is known in which a locking arm is hinged to the socket housing, which secures a plugged into the insertion of the socket plug. Laterally on one of the two locking arms, a latch is provided with a latching hook, which engages in a latching tab on the socket housing to secure the lock and can be released again by an unlocking. In this case, there is the disadvantage that the lock does not act on the lid in the closed state, so that the cover can be lifted from its closed position, for example during cleaning of the socket after contamination, so that moisture penetrates into the socket and the electrical circuit. This is especially true in the case of a frequently used cleaning with high-pressure cleaners. Other disadvantages of the connector described here are that the user must activate the lock separately after plugging the plug into the socket, so that this may also be forgotten. Furthermore, the lid does not close on its own and can be kept open in the open position by the locking mechanism. In addition, the locking hooks which produce the locking may break off when a high tensile force acts on the plug. For safety reasons, it is necessary that the latching solves when a certain tensile force is exceeded, in order to avoid damage to the electrical system in the event of an accident. However, it is advantageous if the socket itself is not damaged by this forced release.

priority The object of the invention is to propose a socket at the lid in its closed state, the insertion of the Socket reliably seals and, for example, too a high pressure cleaning of the socket allows without the moisture enters the electrical system. Other aspects the invention are that the locking of the plug in the Plugging into the insertion opening should be done automatically and a reliable emergency release of the Plug at a certain tensile force on the in the socket plugged in without damage to the socket becomes.

A reliable sealing of the insertion opening through the lid is inventively achieved in particular by the fact that the locking mechanism has a lock which locks the lid of the socket in the closed position. Thus, by providing a lock for locking the lid of the socket in the closed position, the lid is secured against unintentional opening, for example during cleaning by means of a high-pressure cleaner. Preferably, the same lock is also designed to lock a plug inserted into the socket, so that the lid and plugged into the socket with the same mechanism of the locking mechanism are locked. Further, an unlocking mechanism associated with the locking mechanism for unlocking the plug inserted into the socket is formed such that either the plug or the cover is unlocked by the same operation depending on the state of the socket. For this purpose, the unlocking mechanism preferably acts on the lock for both the opening of the lid and for removing the plug.

The Lock can be used as a movable, especially on the box body articulated element may be formed, which in a surrounding the insertion opening Range of the socket is swung. Preferably, it has a Part of the lid and the inserted plug form-fitting encompassing Edge on so as to lock the lid or the plug to reach. Thus, the lock engages directly to the locking part, d. H. the plug or the cover. The barrier So it is similar to a latch in the direction of the insertion slidable to form fit in a holding projection to engage the lid or on the plug. In contrast to The prior art thus finds no locking on a separate Locking element instead, but by engagement with the parts to be held yourself. By dispensing with the additional locking element on the box housing, the reliability of the Increased socket because no errors occur on these parts or they can break off.

According to one Another preferred embodiment of the invention the lock as a multi-arm strap, especially as two-armed Bracket, be formed, which is movable on the socket housing set, in particular hinged, is and from different directions can be moved to the insertion. By the Move in the direction of the insertion come the hanger arms in engagement with the parts of the lid or plug to be held, For example, provided thereon retaining projections, the embraced by an edge on the lock form-fitting become.

at two-armed ironing the arms are upholstered on the insertion preferably opposite each other arranged and movable towards each other. In this arrangement will achieved a particularly reliable locking effect. simultaneously can by the opposite direction of movement of the hanger arms a defined emergency or forced release are provided, without causing any damage to the socket or the Locking mechanism comes. This is special achieve good, if the direction of movement is substantially radial is, with deviations from the radial direction of movement, for example due to a pivoting movement of the bail arms occur if this can be a possibly even common pivot axis are pivotally fixed to the socket housing. Preferably is the lock, for example, through the socket housing as an abutment attacking springs or the like. A clamping force generating Elements biased in the locking direction to after insertion of the plug and after closing the lid one automatically to reach into effect locking.

It is particularly advantageous if the hanger arms equal or are mirror images of a common and Linkage are fixed to the socket housing. So will ensure that the strength and motion conditions the arms are as similar as possible, to achieve a uniform locking.

According to the invention the lock of the locking mechanism biased in the locking direction be around the plugged into the socket and the closed Automatically lock the lid in its respective end position. This has the advantage that - depending on the action of the user - the Plug automatically locked after insertion and thus secured is. Even the lid locks automatically in the closed position, so that the electrical circuit from water ingress or pollution is protected without the locking by the user must be activated separately. This becomes common in practice to forget. It is also conceivable that the lid or in the insertion Inserted plug trigger the locking mechanism, in particular when they reach their final positions. In particular, can be advantageous also be a combination of these elements.

Further It is advantageous if the socket has a release mechanism with an actuating element and a relative thereto movable Entriege ment element having, wherein the unlocking element acts on the lock. In particular, the unlocking causes on actuation the actuator a movement of the lock or bail arms from its locking position to a release position. By doing the actuator and the unlocking relative can be moved to each other, in the context of locking and unlocking different movements are realized that it allow the end and locking mechanism constructed from the same components and comfortable handling with automatic locking of the plug in the plug-in position and the lid in the closed position allows.

Preferably, the unlocking element provided in the unlocking mechanism has an unlocking position in which the catch, for example the bar or strikers, is held in a release position in which the insertion of the plug without actuation of the actuating element of the unlocking mechanism is possible. Unlocked position means that the unlocking is held without external force in the unlocked position, without the actuator must be kept. Here by a two-hand operation is possible in which the lid of the socket is held open with one hand and plugged with the other hand of the plug into the insertion of the socket. When the lid is open or kept open, an actuation of the unlocking mechanism for holding the lid is no longer necessary.

According to one preferred embodiment of the release mechanism are as Actuating a lever and unlocking provided a cam drum, the cam drum and the lever are mounted coaxially on a pin pivotally. Preferably have the lever and the cam drum stop surfaces for action on top of each other, so that basically relative to each other movable elements can interact and in certain relative arrangements to each other an element at a Movement moves the other element.

In Further development of the invention, the unlocking, in particular the above-described cam drum, a ramp having, which with a guide portion of the lock cooperates, wherein the bevel the guide section the lock moves in the direction of movement of the lock. In this movement So the lock is between its locking position and its unlocked position postponed.

Around not just an automatic locking of the plug in the inserted State to reach, but also the socket after pulling out the plug from the insertion automatically close and to lock, the lid according to the invention, for example biased by a pivot spring in the closing direction be. Preferably, the closing force of the lid is sized in that a projection formed on the cover abuts on the Entriegelungselement in the locking position of this first leads to a release position to the locking element to get past the closed position and the lock cause the lid by the unlocking element due its own spring bias back into the locking position is returned. The applied through the lid Closing force must therefore be greater than the restoring force of the lock. Because the closing force of the Lids so a significant force required, can for Reduction of the closing speed of an open Lid when releasing a ratchet on the hinge of the lid be formed, the movement inhibiting with the socket housing cooperates and accidentally letting go of the lid in the open position on the one hand a loud ratcheting noise causes and on the other hand gives the possibility of a finger to move away fast enough so that he is not between the edge of Insertion and the lid is clamped. Should the fingers are still trapped, due to the reduced momentum, with which the lid closes, the probability significantly reduced for an injury.

According to the invention the release mechanism having a driver, which upon actuation of the actuator to engage is formed the lid or the plug. This will be at unlocking the lid or plugged into the socket Plug automatically pushed out of its disfigurement, allowing handling is made easier and safer. This driver can when closing the lid and / or when plugging a plug for actuation be formed of the locking mechanism to an automatic To achieve locking.

Further is advantageous according to the invention, in the lid to provide a lid seal, which with a the insertion surrounding wall or a seal arranged thereon. The wall or the seal disposed thereon may be on its outside have a tapered sealing surface. In the Cover gasket is then one to the chamfer of the sealing surface adapted, also bevelled sealing surface provided which may preferably also have sealing lips. At a special advantageous embodiment, the chamfer is such chosen that by the rotation about the pivot axis defined movement of the lid the sealing surface of the lid seal, optionally with the sealing lips, at least approximately tangential to the sealing surface of the wall or of it arranged seal engages. This will be a high Sealing effect even with a certain play in the lock with almost constant contact pressure over a certain opening range achieved a certain play in the lid closure and the Locking allows. This aspect of the invention may also be according to the invention at sockets without the above-described locking the lid the socket can be used as this type of cover gasket the tightness of the insertion increased overall and small tolerances in the closed position of the lid balances that biased both in a closing direction Cover as well as in the previously described lock, preferred Of course, in the combination, too.

According to a preferred embodiment of the invention, a separate contact carrier insert can be inserted into the socket, so that the contact region of the contact carrier insert is arranged in the insertion opening of the socket. In this case, the contact carrier insert can be both conventional Strom- or power supply terminals as well as a bus connection, for example for a CAN bus have. On the side opposite the side intended for connection to the plug, the socket can also have two connection areas, for example plug connections, one of which serves the power supply and analog switching connection to a vehicle electrical system and a second connection to a bus system. Of course, the socket according to the invention can also be realized with a one-piece in the socket formed, for example, injected as part of the injection molding process into the socket contact carrier insert.

Around the detachable from the socket housing contact carrier insert can be easily set in the socket, the contact carrier insert according to the invention be latched into the socket, for which preferably at the peripheral edge of the contact carrier insert Latching tabs are provided in the recesses on the wall and / or an inner wall of the wall area surrounding the insertion opening of the socket housing.

In 1 is a power outlet 1 with a socket housing 2 shown in the one insertion 3 , in 1 through a lid 4 covered, is formed. The lid 4 is over a spiral pencil 5 on the socket housing 2 hinged, wherein on the spiral pin 5 a thigh spring 6 for the lid 4 is set, which the lid 4 biased towards its closed position.

The socket also has a locking mechanism 7 on, in the presentation of the 1 through two each on one side of the lid 4 arranged guard 8th of the socket housing 2 is covered and will be described in detail later. The guard 8th serve to mechanical influences on the locking mechanism 7 intercept.

The proposed outlet 1 serves the electrical connection between a towing vehicle and a trailer, the socket typi is mounted on the towing vehicle and a plug of the electrical system of the trailer in the socket 1 is inserted. The illustrated form of the socket is intended in particular for use on work vehicles, for example in agriculture or construction, in which it is important to the outlet 1 and in particular the locking mechanism 7 Protect against mechanical influences that may cause malfunctions.

The locking mechanism 7 serves both the locking of one in the insertion 3 the socket 1 plugged in 9 who in 1 but not shown. At the same time serves the locking mechanism 7 the locking of the lid 4 in the closed position, as in 1 shown.

For unlocking is on the socket housing 2 the socket 1 a release mechanism 10 set of which in 1 only one as an actuator 11 trained lever is shown.

At the corners of the square in the basic form of socket housing mounting holes 12 for screwing the socket 1 provided on a mounting surface, not shown.

2 shows the socket 1 from the back, which is fixed on the mounting surface. From the the insertion opening 3 having front of the socket are merely a protective bar 8th and the lever 11 the unlocking mechanism 10 to recognize. In the interior of the socket 1 is between the mounting holes 12 a contact carrier insert 13 taken, the one in 2 not shown contact attachment 14 has, in the insertion 3 of the socket housing 2 is arranged. On the other hand, it can be seen at the back of the contact carrier insert 13 trained plug connections 15 which is the electrical connection of the socket 1 serve to the electrical system of the vehicle. In the case shown are a round connector 15 for connection to the conventional electrical system and a rectangular connector 15 intended for connection to a CAN bus system.

The contact carrier insert 13 is as in the socket housing 2 insertable plate 16 formed, the latching tabs on their side surfaces 17 that has latching recesses 18 of the socket housing 2 for fixing the contact carrier insert 13 in the socket 1 engage. The preferably on several sides of contact carrier insert 13 and socket housing 2 trained locking connection allows easy installation of the contact carrier insert 13 in the socket 1 and allows, if necessary, a release of these two parts.

3 shows essential parts of the socket 1 in an exploded view. In particular, those not previously described in detail to the locking mechanism 7 and the unlocking mechanism 10 belonging elements are shown, which are explained below.

The locking mechanism 7 points as a lock 19 two brackets or bracket arms, which are constructed in mirror image to each other and the insertion 3 of the box housing 2 largely enclose. At mutually facing ends, the bracket 19 interlocking hinge tabs 20 on, by means of a tension pin 21 such on the socket housing 2 be set that the approximately half-round trained hanger 19 the insertion opening 3 enclose and at the hinge straps 20 opposite edges trained edges 22 by turning the temples 19 around the dowel pin 21 in the direction of the insertion opening 3 displaceable or from the insertion opening 3 are wegbewegbar. The movement of the lock 19 in the area of the edges 22 , which is the locking of the plug 9 or the lid 4 serve, is substantially radially to the insertion 3 , To the locks 19 in a locking direction, ie in the direction of the insertion opening 3 to harness are at the straps 19 compression springs 23 arranged in the installed state on inner surfaces of the guard 8th repel.

At the hinge lugs 20 opposite end of the hanger 19 is also a guide section 24 provided in the form of guide pins, with the unlocking mechanism 10 interacts with the hangers 19 from its locking position against the force of the compression spring 23 to move.

The unlocking element 10 points to this next to the trained as a lever actuator 11 a relatively movable unlocking element 25 in the form of a cam drum, which together on one on the box body 2 stored pen 26 are rotatably and relatively fixed to each other movable. By a thigh spring 27 that too on the pin 26 is stored, is the lever 11 in one direction, in the illustration according to 1 the upward direction, biased. The relative to each other on the pen 26 freely movable mounted actuator 11 and unlocking element 25 show in 6 clearly recognizable stop surfaces 28 on, in a certain relative position of actuator 11 and unlocking element 25 cause a movement of the actuator 11 on the unlocking element 25 is transmitted. As a result, move on the unlocking 25 trained ramps 29 connected to the guide sections or guide pins 24 the coat hanger 19 cooperate, and so a locking and unlocking of lids 4 or plug 9 cause.

This function of the locking mechanism 7 and the unlocking mechanism 10 will be described in detail below.

To show the 4 and 5 the socket 1 in supervision, being in 4 a locked and in 5 an unlocked position of the locks or stirrups 19 is shown. For the sake of clarity, the socket housing 2 hidden in the illustrations.

In 4 you recognize the lid 4 with a holding projection formed on its edge 30 , The encompassing edge 22 the coat hanger 19 surrounds the retaining projection 30 and holds the lid 4 therefore warped in its closed position. In this position are the guide pins 24 the coat hanger 19 through the ramp 29 serving as unlocking cam barrel 25 not pressed outwards.

5 now shows the unlocked state of the locking mechanism 7 in which the retaining projections 30 of the lid 4 not by the encompassing edges 22 being held. These were the hangers 19 in the area of the encompassing edges 22 through the unlocking mechanism 10 essentially moved radially outward by the stirrups 19 by the hinge straps 20 with the dowel pin 21 formed hinges were moved away from each other. This movement was made by operating the lever 11 achieved that the cure ventrommel 25 has moved so that the guide pins 24 the coat hanger 19 by running along the ramp 29 moved away from each other.

With reference to the 6 to 13 Below is the course of movement when plugging a plug 9 into the socket 1 starting from a locked lid 4 up to an inserted plug 9 described ( 6 to 12 ), in which 14 then the first step in pulling out the plug 9 from the socket 1 shows.

6 shows that through the hanger 19 in its closed position locked lid 4 in the side view, again with the connector housing 2 - As in the following figures - is hidden for clarity. For this purpose, the edge shown in this illustration engages only from behind 22 the retaining projection 30 of the lid 4 , In this position is the lever 11 the unlocking mechanism 10 , biased by the leg spring 27 , pushed up, leaving the stop surfaces 28 of the lever 11 and the barrel drum 25 spaced apart from each other. The curve drum 25 is in its one end position in which the guide pin 24 of the temple 19 through the ramp 29 not against the force of the compression spring 23 is pushed out of its locked position.

To unlock the lid 4 becomes the lever 11 against the biasing force of the leg spring 27 , ie in the illustration according to 7 pressed down, leaving the stop surfaces 28 of the lever 11 and the barrel drum 25 abut each other. This turns the cam drum 25 moved, so that the ramp 29 relative to the guide pin 24 of the temple 19 moved and the strap 19 doing so against the restoring force of the compression spring 23 pushes outward. There is the encompassing edge 22 of the temple 19 the retaining projection 30 of the lid 4 free. The latter is according to the three-dimensional view 8th to clearly recognize which in 7 described state corresponds.

As 9 shows, simultaneously pushes in the area of a lid projection 31 in the area of the unlocking device 10 from the inside of the lid 4 in the direction of the socket housing 2 extends, trained driver 32 the cam drum 25 on this lid projection 31 on, leaving the lid 4 slightly raised against its spring force. Lifting the lid 4 is synonymous with a direct comparison of 6 and 7 to recognize.

The the operating lever 11 downward pressing opening movement is now continued until the guide pin 24 of the temple 19 the ramp 29 leaves and in a flat section 33 the cam drum 25 is applied, which is perpendicular to the direction of movement of the guide pin 24 of the temple 19 is aligned. This position is in 10 shown.

During the opening movement of the lock 19 in which the guide pin 24 over the ramp 29 runs, the spring force of the compression spring extends 23 off to the cam drum without operating the lever 11 to turn back to their original position and to cause a re-locking of the lid, if, for example, the actuator 11 is released.

When the guide pin 24 however, in the area of the flat section 33 the cam drum 25 which is perpendicular to the direction of movement of the guide pin 24 is arranged, the lock is 19 held in a release position. Therefore, the unlocking element remains without external force 25 (respectively the curve drum 25 ) in an unlocked position.

At this stage, however, the Be actuating element released as long as the lid 4 with the lid projection 31 still on the driver 32 the cam drum 25 rests, due to the bias of the lid 4 as external force the cam drum 25 turned back, and the socket 1 go in their in 6 illustrated closed position on.

Will the lid 4 however, open before the lever 11 is released, the cam drum remains 25 in its unlocked position, in which the bracket 19 occupies a release position. The actuator 11 is due to the spring preload of the leg spring 27 then led back to his free position. This position is in 11 shown, with the lid 4 against the closing force of the leg spring 6 must be kept open manually.

As long as the lid 4 is stopped, a plug can 9 in the insertion opening 3 the socket 1 with the contacts 34 be inserted. When inserting the plug 9 pushes this with its outer edge, such as a bayonet ring or the like projection on the driver 32 the cam drum 25 , as in 12 shown. This turns the cam drum 25 from its unlocked position, in which the guide pin 24 at the flat section 33 abuts, moves away, leaving the guide pin 24 along the ramp 29 slides back so that the lock or the hanger 19 in the direction of the inserted plug 9 moved and locked this.

This encompasses the edge 22 of the temple 19 one on the plug 9 trained retaining projection 35 so that the plug is now securely locked, as in 13 shown. The relative position of locking mechanism 7 and unlocking mechanism 10 corresponds to the representation in 6 , where instead of the lid 4 now the plug 9 through the encompassing edge 22 is held.

Because the encompassing edge 22 , as in 13 is clearly visible, has a phase angle, is at a correspondingly high pull on the plug of the bracket 19 from its locked position against the clamping force of the compression spring 23 pressed so that the desired emergency or forced release takes place in this way, without causing damage to the locking mechanism 7 comes.

14 shows as with a pressure on the actuator 11 To release the connector, the cam drum 25 is moved, so the driver 32 presses against the bottom of the plug, at the same time the locks 19 be moved in the manner already described to the outside. This will cause the plug 9 in the socket 1 solved and can be deducted.

15 now represents an error case in which the plug 9 from the socket 1 is pulled out before the locks 19 can lock it. An analogous condition occurs when the cam drum 25 is rotated back from its unlocked position by an external force. In this case, the locks return 19 back to its locked position and the lid 4 can not return to its closed position.

Therefore, it is provided that the restoring force of the lid 4 through the thigh spring 6 is greater than the biasing force of the bracket 19 through the compression spring 23 so that the lid 4 the hills 19 pushes to the side to return to the closed position. For this, the lid 4 be beveled or chamfered at its lower peripheral edge, so that the bracket 19 easier to be pushed apart.

Regarding 16 and 17 Now, another, even independent aspect of the invention will be described, which relates to the formation of the seal between the insertion 3 and the lid 4 is directed.

These are in the lid 4 a lid seal 36 and on one the insertion opening 3 surrounding inner wall 37 of the socket housing 2 a seal 38 reared. The seal 38 serves both the sealing against the lid 4 as well as the seal against an inserted plug 9 , such as in 12 and 13 to recognize.

The sealing between the seal 38 and the lid gasket 36 will be referred to below 16 and 17 explained in more detail.

The on the inner wall 37 mounted seal 38 has a tapered sealing surface 39 on top, with a bevelled sealing surface 40 the lid seal 36 cooperates, taking on the beveled sealing surface 40 the lid seal 36 additional sealing lips 41 can be provided.

16 shows a completely closed lid 4 so that the lid seal 36 and the seal 38 abut each other at their sealing surfaces and achieved a sealing effect. Due to the tapered sealing surfaces is how 17 to be taken during the closing movement of the lid 4 a substantially tangential approach of the lid seal 36 to the seal 38 achieved, so even with not completely closed lid 4 a sufficiently high sealing force between the two tapered sealing surfaces 39 . 40 is generated, so that here a reliable seal achievable is.

This sealing effect is achieved regardless of whether the lid 4 additionally by the locking mechanism 7 is locked.

16 and 17 show a further inventive feature of the socket 1 which may also be provided independently of the provision of the lock described. In the area of the spiral pin 5 formed axis of rotation of the lid 4 this has a peripheral edge with individual ratchets 42 on that on a radius with respect to the axis of rotation 5 are formed on the circumference of the lid. Due to the different pressure angles of the individual ratchets 42 not shown projections of the socket 1 , in particular of the socket housing 2 , is the power of ratchets 42 on the lid 4 when closing larger than when opening. Despite the movement inhibition in the closing direction, which has an effect on the momentum during closing, but not on the closing force, the lid is therefore easy to open.

These ratchets 42 engage the projections of the socket housing, not shown 2 on, wherein the engagement force is not strong enough, the restoring force of the leg spring 6 to keep. It delays the shooting of the lid 4 However, and takes the closing movement the momentum. At the same time a ratchet noise sounds typical for ratchets. This will cause an accidental release of the lid 4 on the one hand on the closing of the lid 4 attention is drawn and on the other hand enough time remains to the finger from the lid 4 take away and avoid pinching the finger. If the finger is still pinched, the reduced momentum on closing reduces the risk of injury.
