Description

The invention relates to a device for producing and releasing an electrical connector, the first and the second connector part to be connected in forced operation relative to each other and slid together device parts when merging together and separated from each other in their separation movement, in particular for electrically contacting circuits of a Insertion device with circuits of a receiving this device frame.

For devices of this type, it is already known to mount the two connector parts so that they are inevitably connected together when merging their equipment parts when the two parts of the device reach an end position. An example of this application of connectors is the circuit card, which is inserted into a device frame and engages in reaching its end position with a mounted on her connector part in a mounted on the device frame connector part. Another example is a plug-in device with a housing which is inserted into the device frame and is also electrically connected when reaching an end position on the two parts of a connector with circuits in the device frame.

As long as sufficient space is available in the direction of the depth of the equipment frame on both supports, the plug connection can be realized in the back of the device frame, ie, the two connector parts are then at the front end in the insertion direction of the one carrier, so z. As a circuit board, and mounted in the back of the device frame. However, there are also applications, in particular in box-like plug-in modules and the device frame receiving them, in which the position of the connector in the manner described above is undesirable because of limited space and aspired small depth and ease of handling of a device. This applies z. B. for plug-in devices that need not only be accessible for maintenance purposes, but their use must be possible even if they are outside their equipment frame.

Such devices are z. B. banknote containers that are inserted in cash and / or cash dispensing machines, but must be removed regularly for emptying or refilling. Their front and back surfaces must be accessible and removable for trigger mechanisms. An electrical connector is undesirable in these areas, and they have therefore arranged on a side of the housing or on the inside of the insertion opening of the machine frame.

In the frequent use of a module, ie when making and separating the connector and the handling of plug-in devices, a lateral arrangement of the connector is a hindrance, since their two elements protrude laterally and thereby cause an increased space requirement, which serves only the connector and the leadership properties affected the two parts of the device during forced operation.

From the document US 5,622,511 A For example, a housing for a floating connector is known which can be used in conjunction with a standard connector. The housing has two alignment pins that align with the connector of the standard connector with a complementary connector. The standard connector and housing are located on the back of a device.

The object of the invention is to provide a device for producing a plug connection, which allows a safe contact without impairing the leadership properties of the two parts of the device during their sliding movement with the least possible space and ensures obstacle-free handling of a device to be contacted.

The invention solves this problem with the features specified in the patent claim 1. Other features that favor this solution are given in the dependent claims.

By the invention, a connector is realized in the lateral region of the device parts to be electrically connected to each other, not their relative sliding movement disturbs because one of the connector parts is sunk in its device part and the other connector part is moved out of the range of motion on its device part when both parts of the device are in the state of sliding movement.

In the separated state of the two parts of the device is a connector part of its wearer from the side, ie it protrudes into the range of movement of the two parts of the device and is thereby in its connecting position. Become the two parts of the device now brought together and pushed the second part of the device in the first, the first connector part is temporarily moved out of its connection position and allows unimpeded sliding movement of the two parts relative to each other until it slides further into the recess of the second device part by the spring force dips and then facing the second connector part again, so that it is plugged together by further sliding movement with the second connector part.

When disconnecting the two parts of the device, the connector is first released again, as long as the recess of the second part of the device is still in the range of the movably mounted first connector part. Upon further separation movement, the recess is moved out of this area, and the second device part then acts again on the movable holder of the first connector part and moves it out of the recess, so that both parts of the unit can be freely separated from each other.

The invention avoids an arrangement of the connector parts in areas where they can affect the handling of a plug-in device. Since the one connector part can be moved out of the region of the positive guide, while the other connector part is arranged in a recess, the entire device can be arranged in the region of one longitudinal side of the two device parts, without disturbing their mutual guidance. This creates a space requirement only by the recess on one of the two parts of the device, which is dimensioned so that they can accommodate both connector parts and their separation movement allows.

In Fig. 1A to D the various positions are shown, the two can take in forced operation relative to each other movable device parts, each carrying a connector part. As a connector parts each have a connector strip and a female connector may be provided, as they are known for the electrical wiring of devices.

At the in Fig.1A to D schematically shown arrangement is a rack 10 and a slide-in therein slide 20. This may be a circuit card or circuit board in the simplest case, on which electrical circuits and components are arranged in an insertion end position with other circuits in the frame frame 10th are electrically connected via a plug connection. The application of the invention to be described here relates to the use in a box-shaped plug-in device, in particular a banknote box. In this banknote container preferably at least one electric drive and / or at least one sensor is arranged, which is electrically connected via the plug connection parts to a control circuit arranged outside the value note container. Alternatively or additionally, at least one sensor can be arranged in the banknote box, which is connected via the plug connection parts to a control circuit arranged outside the banknote counter.

In Fig. 1A to D the rack 10 and the plug-in unit 20 are each shown in a view from above, wherein the device frame 10 is shown in a horizontal section. Fig. 1A shows a first position in which the plug-in device 20 is already inserted from the left into the equipment frame 10 so far that it meets with its front side edge on a pivot arm 11 which is pivotally mounted at 12 in the frame frame 10.

The pivot arm 11 carries at its free end a plug connection part 13 in an angled position such that it is aligned in the illustrated position of the pivot arm 11 on a further connector part 21 which is secured in a lateral recess 22 of the plug-in device 20 and the counterpart to the Plug connection part 13 is.

The plug-in device 20 strikes with its front side edge on a control edge 14 of the pivot arm 11 and pivots it on further sliding movement against the force of a leaf spring 15 out of the range of motion. The leaf spring 15 is articulated at 16 in a manner to be described with the pivot arm 11 and fixed at 17 to the device frame 10 fixed.

During the movement of the pivot arm 11 as a result of the further sliding movement of the plug-in device 20 in the direction of the arrow, the leaf spring 15 is deflected so far that it finally in Fig. 1B shown position, in which he swivel arm 11 with the connector part 13 practically completely out of the range of movement of the two parts of the device 10 and 20 for the connector parts 13 and 21 is moved out. The front edge of the recess 22 of the plug-in device 20 is located in this position just before the free end of the pivot arm 11 so that it can not change its position until reaching this position of the plug-in device 20.

With continued sliding movement of the plug-in device 20 in the illustrated arrow direction, the pivot arm 11 can engage by the force of the leaf spring 15 in the recess 22 of the plug-in device 20 and thus brings the held him connector part 13 back into the connecting position in which he the connector part 21 of the plug-in device 20 faces and the in Fig. 1C is shown.

Fig. 1D shows finally the end position of the plug-in device 20, in which the two plug connection parts 13 and 21 are connected to each other and the plug-in device 20 is fully inserted into the machine frame 10. When the plug-in unit 20 from this position in the in Fig.1D shown arrow direction is pulled to the left from the machine frame 10, so meets the leading edge 23 of the recess 22 on the leaf spring 15, which now forms an obliquely to the sliding path control surface and is moved out of the range of movement of the insertion device 20. This will restore the in 1B shown position of the swing arm 11 reaches, in which he does not hinder the sliding movement.

From the movement sequences described above, it can be seen that the recess 22 must have a length in the sliding direction, which corresponds at least to the length of the mated connector parts 13 and 21 plus their mutual distance immediately after the release of the connector. Its depth is determined by the thickness of the plug connection parts 13 and 21.

In Fig. 2 is the in Fig. 1 shown only schematically device in a practical embodiment. This device belongs to a banknote container 20, which is inserted into the device frame 10 of an output device, which is only partially shown. The pivot arm 11 has at its end mounted a slot 12 which is guided on a mounted in the device frame 10 pin 12a, which in turn is held in a mounted in the apparatus frame 10 bearing bracket 12b. The pivot arm 11 has at its other end a hinge axis 16 to which one end of the leaf spring 15 is fixed, so that here a hinge connection between the leaf spring 15 and the pivot arm 11 is formed. The leaf spring 15 is attached to the machine frame 10 with its other end 17 by two screws 17 a. If this arrangement by the sliding movement of the banknote box 20 when displayed in Fig. 2 is pressed down, so the associated extension of the existing of the pivot arm 11 and the leaf spring 15 mechanism through the slot 12 of the pivot arm 11 is possible.

Fig. 2 shows the position of equipment frame 10 and banknote container 20, in which the connector with the Connector parts 13 and 21 is made. The length of the recess 22 is dimensioned so that a movement of the banknote box 20 to the left is possible to first disconnect the connector. Thereafter, a guide projection 18 made of a slidable material located at the free end of the swing arm 11 abuts the right end of the recess in the area 23, which forms a concavo-convex guide surface for the guide projection. This is performed without substantial resistance so that the entire pivot bracket with the pivot arm 11 and the leaf spring 15 is moved out of the range of movement of the banknote box 20.

In Fig. 3 In perspective, a banknote container 200 is partially shown, which has on its longitudinal side a recess 220 in which a connector part 210 is arranged, the contact elements are aligned in the longitudinal direction of the banknote box 200. The connector part 210 is mounted in a holder 212, the outside of which lies in the sidewall plane of the banknote box 200. The bottom 211 of the recess 220 on both sides of the holder 212 via inclined surfaces 213 in the longitudinal side of the banknote box 200 via. The right edge 230 of the recess 220 is similar to FIG Fig. 2 shown arched formed to facilitate the sliding of a holder, not shown here for a second connector part.

Fig. 4 shows the view of a mounted in the wall of a device frame 100 plug part 130. Its holder corresponds to the in Fig. 1 and Fig. 2 shown principle. The plug part 130 is screwed to a support 131 with a hinge part 180, the bearing journal 161 and 162 with an upper pivot arm 111 and a lower pivot arm 112 is pivotally connected. The screwing of the carrier 131 with the hinge part 180 also serves to hold the ends 153 and 154 of two leaf spring arms 151, 152 of a Blattfeder150, the other end 170 is fastened with screws 171 and 172 on the wall of the machine frame 100.

In Fig. 5 is the in Fig. 4 shown arrangement in perspective without the wall of the device frame 100 shown. It can be seen that the carrier 131 is attached to the connector part 130 to a fork-like support whose forked parts are formed by the two pivot arms 111 and 112 and by the two leaf spring arms 151 and 152, the ends 153 and 154 between the support 131 and the hinge part 180 are held by the screw. The hinge part 180 connects the pivot arms 111 and 112 with the two leaf spring arms 151 and 152 on the pivot pins 161 and 162 (FIGS. Fig. 4 ) And thus creates a rigid structure for supporting the connector part 130. On its sliding side of the joint part 180 has a rounded sliding surface 181, which slides over in conjunction with Fig. 2 described edge 23 of the recess of a plug-in device 20 facilitates.

The two pivot arms 111 and 112 have their in Fig. 5 front ends each have a slot 120 which is guided on a pin 121 and 122, which belongs to a bearing angle 123. This one is in the in Fig. 5 Attached not shown wall of a device frame.

If the in Fig. 5 The mechanism shown in the side wall of a device frame is fixed, the contact elements of the connector part 130 are aligned in the longitudinal direction of the side wall, so that an electrical contact with a connector part 210 of the in Fig. 3 shown type can be produced when the in Fig. 3 shown banknote container 200 is inserted into the machine frame.

An embodiment of the invention has been described above, in which a movable connector part is mounted on the wall of a device frame and the other connector part is mounted in a stationary device stationary. It is also possible to mount the one connector part in the plug-in device with a movable holder described type and to attach the other connector part to the device frame in a fixed position.

Instead of a leaf spring, another spring, such as a coil spring or a plate spring for resilient biasing of the movable connector part can be provided. In this case, at the free end of the swivel mount an additional mechanical connection with the supporting element, ie z. B. with the wall of a device frame, may not be required, which depends on the shape of the spring used.
