Description

The invention relates to a multi-pole electrical connection system for a electrical device, in particular for a lamp.

Electric lights are usually via connecting or branch lines connected to an external supply line. The connecting cable is included via a multi-pole electrical connector to the supply line connected. The branch line is connected to the luminaire usually in that the external lines in a first operation must be passed through the housing wall of the luminaire housing and the line ends of the connection line or their conductor end sleeves on site connected to the connection terminal located inside the housing become. In practice, this means connecting the branch line to the lamp requires a lot of manual effort.

The German patent application DE 100 11 613 A1 shows a device for Installation and electrical connection of lights. Besides that actual lamp body a connection box for connecting the electrical Power supply provided, with the lamp body and connection box each at least one complementary electrical connection element include and are releasably connected to each other via a snap connection.

The invention has for its object a particularly simple and quick connection of an electrical device, especially a lamp to enable an electrical supply line. This task is accomplished by a Connection system according to claim 1 solved.

The connection system according to the invention has one with the electrical device connected lower connector part, which has a first conductor connection to Connecting a supply line, a second conductor connection to the Connecting a connecting line, a number of mounting elements for Holding the lower part of the connector on a mounting surface of the electrical device, and a third conductor connection with a number of plug elements for Formation of an electrical connection with a plug upper part for Connect a supply line, and a number of connections elements for forming a mechanical connection with a Plug upper part includes.

This connection concept is based on the consideration of an electrical device to be provided with a connection device in the form of a plug lower part, which allows the device to be connected to an electrical supply line both conventional wiring and modern To provide plug connection.

In the event that the device is connected using a conventional connection technology the supply line is to be connected is a first conductor connection provided that receives an incoming supply line. With this The first wire connection is internally wired to a second wire connection a connecting cable for connecting the lower part of the plug with the electrical Consumer, for example a lamp, can be connected.

In the event, however, that none for connecting the electrical device conventional connection technology is to be used is another Conductor connection provided for connecting a supply line. With help this third conductor connection, it is possible to pass through the lower part of the connector simple plug-in to connect electrically with a plug upper part, which is connected to a supply line. In this case, this indicates Connector base for mechanical connection with the Upper part of the plug. This third conductor connection is also internal to the second Wire connection wired so that an electrical connection is then between the supply line and the electrical consumer is ensured.

According to the teaching of claim 2, the first and / or the second comprises Conductor connection preferably plug elements. This is a particularly quick one and, especially when using a hide-proof connector system, error-free connection of the supply line guaranteed.

The connection of the supply line or the connecting line on However, the lower part of the plug can also be produced by conventional contacts be (claim 3). Is connected to the electrical consumer leading connecting cable to the lower part of the plug through a clamping contact, for example, spring clips or insulation displacement clips. This can also be done by using such clamping contacts Connect the connecting cable easily and yet safely.

The lower part of the plug is attached to the electrical device with the help of assembly elements held. It when the fixation of the lower connector part in the Inside the device housing. Plug elements of the lower part of the plug are thereby advantageously in a housing opening in the housing wall of the electrical device arranged such that they for the connector elements of the Plug upper part are freely accessible. The assembly elements are preferably thus designed to fix the lower part of the connector to a housing wall. In particular, the use of locking elements in the form of locking lugs advantageously such that the locking lugs as mounting elements on the lower connector part in engage the corresponding recesses on the housing wall (claim 4).

The plug elements of the third conductor connection are preferably plug sockets (Claim 5), so that a corresponding connector element on most light and flexible plug upper part simply into the plug lower part fixed to the device can be introduced.

To form an additional mechanical fuse, the connector upper part and lower part connecting elements. In a particularly advantageous Embodiment, a snap connection is formed. To this end is a corresponding recess on the lower part of the connector (claim 6) intended. However, there are also other snap or snap connections conceivable. Of course, others can additionally or alternatively mechanical fuses, for example screw connections, are used become. The connecting element of the plug upper part runs in Plug cross direction, so is, in particular in the longitudinal direction of the plug running supply line, a particularly simple and unobtrusive Assembly possible.

As an additional mechanical fuse, the lower part of the plug has one another embodiment of the invention, a receiving opening (claim 7). This serves to accommodate a corresponding connecting element of the Plug upper part and thus for the formation of a fuse and for training a mechanical guide for connecting the lower part of the plug and Plug top.

According to the teaching of claim 8, the plug base is finally with one Plug upper part connected. The connection is made by a number of connecting elements (Claim 9). Will advantageously be a snap connection is a locking hook on the connector upper part (Claim 10) provided. If other connections are to be trained, can also use snap, snap or screw elements become. As an additional mechanical fuse, the upper part of the plug has a another embodiment of the invention a running in the mounting direction Guide pin on (claim 11) in a corresponding receiving opening of the lower part of the connector in the final assembly position forms a press fit. The The guide pin serves both to guide the upper part of the connector during assembly as well as the formation of a safe mechanical Connection in final assembly position. The mechanical connection between The upper and lower part of the plug can be designed to be detachable or non-detachable. In the case of a permanent connection, the mechanical structure of the Connection system, since no opening mechanisms are provided have to.

In the simplest case, the upper part of the plug consists of a simple cover, the after the connector elements of the third conductor connection of the lower connector part lock outside (claim 12). Such coverage is advantageously always present when the electrical device on the first conductor connection is to be connected to a supply line since in In this case the third conductor connection does not have to be used. Will, as in Claim 13 proposed, but used a plug top that itself has a further conductor connection, this is a particularly advantageous one Implementation of the invention realized. After that it is possible to have a spatially of the separate connection module in the form of the electrical device to be connected to provide a connector upper part. This connector top can independent of the electrical device in advance of the installation Supply line can be connected. The same applies to that in the device provided lower part of the connector. This can also be done before the actual Installation must be connected to the device's internal connection line. To the The electrical device must then be connected to the supply line The upper part of the plug can only be inserted into the lower part of the plug. With the The electrical connection between the upper part of the connector and is inserted Lower part of the connector and thus between the supply line and the connecting line manufactured. At the same time, the connector upper part and the connector lower part become mechanical connected to each other so that a secure contact is guaranteed.

A major advantage of this embodiment is that the electrical device no longer connected to a supply line must be opened. Damage or similar are in this way by effectively avoided from the start. The manual effort when connecting the electrical device is extremely small. In particular, it is when connecting advantageous from luminaires that no complex overhead installation is required is the weight of the lamp during the entire period of Then must be worn. Instead, it can Pre-assembled connector upper part easily and quickly into the one to be connected Device existing plug base can be inserted. By the The principle of insertion of the upper part of the plug into a lower part of the plug according to the invention a particularly simple and extremely quick installation is guaranteed. Because of these advantages, there is a significant reduction in assembly costs possible.

The plug upper part is advantageously designed such that the fourth Conductor connection the connection of the supply line in the longitudinal direction of the plug allows. This results in an extremely low overall height of the connection system reached. It is therefore particularly suitable for use in tight assembly rooms or for an unobtrusive installation, for example on ceilings suitable.

The fourth conductor connection of the Plug upper part preferably plug contacts (claim 14). This will enables particularly simple, fast, yet safe wiring. For this purpose, a connector system is preferably used which is confusion-free Connection ensures. The conductor connection can be one simple plug connector (claim 15) or a plug distributor (claim 16) include, so that the supply line both as a simple connecting line and connected as a branch line, for example in the case of a lighting strip can be.

Of course, the supply line on the upper part of the connector can also be opened conventional way. The conductor connection points to this Clamping and / or screwing contacts (claim 17). Especially The supply line is easily connected when insulation displacement contacts are used (claim 18). The individual heads of The supply line can then simply be stripped into the appropriate insulation displacement clamps.

The upper and lower part of the plug each have at least one, but preferably several connector elements to form the electrical connection between Plug top and bottom part on. Is a plug socket on the lower part of the plug provided, the upper connector part has a corresponding connector element Plug pin on (claim 19). If the plug pin runs in the transverse direction of the plug, see above is, in particular in the case of a supply line running in the longitudinal direction of the plug, a particularly simple and unobtrusive assembly possible.

According to the teaching of claim 20, it is also advantageous if on A cover is provided on the upper part of the plug so that it is on the upper part of the plug results in a kind of housing. On the one hand, the cover serves as protection against environmental influences. On the other hand, the cover serves as strain relief, since it is the through a line opening in the housing supply line in the closed state fixed.
