- FIG. 7 an individual perspective view from FIG. 6.
- Fig. 1 shows a schematic exploded view of the structure of a multi-pole contactor (in the present example, 3-pole or 4-pole with supply connection for the
- the housing 2 of the contactor is made up of three parts and consists of a base housing part 2a for receiving a magnetic drive, an upper housing part 2b which can be placed on the base housing part 2a and a housing cover 2c.
- the connection contacts 4 are shown on both sides, which serve for the connection of incoming and outgoing connection lines.
- the housing 2 can also be formed in two parts or even in one part.
- Parenthesized as alternative connections to the illustrated connection terminals 4a with spring-loaded connection are also connection terminals 4b with screw-type connection.
- connection terminals 4a with spring-type terminals are provided for the housing 2 shown.
- the illustrated cover part 2c is provided for the connection terminals 4a with a spring clamp connection and has a first row of openings 21 for the connection or access of first connection lines 410 with or to first connection means 41 of the connection contact 4a, a second row of (double) Openings 22 for the engagement of a tool (eg screwdriver) and a third row of openings 23 or an opening in the form of an opening slot for the connection of second connection lines 420 with additional second connection means 42 of the connection contact 4.

- the additional row of openings 23 (or the opening slot) provided according to the invention is closed in a preferred embodiment of the invention in the initial state via a cover part.
- the opening can be closed by a reclosable cover part via a snap connection or a film hinge.
- the opening 23 cannot be closed again by one or more separable housing area (s) outlined by predetermined breaking points, which housing area (s) forms the later access area to the second connection means 42. This ensures a particularly simple construction and avoids additional storage and administration costs for separate cover parts.
- connection contact 4a is formed with first connection means 41 in the form of spring clamp connections, while in the alternative embodiment screw clamp connections are arranged instead of the spring clamp connections. Both embodiments have in common the design according to the invention with additional second connection means 42.
- a connection contact 4 according to the invention is preferred by a tongue-like one
- Connection flag formed which is connected to the inside of the device on electrical device conductors is closed or, as in the present case, simply carries a fixed contact 43 as a contact carrier, which has the first connection means 41 (such as screw-type terminals or spring-type terminals) towards the outside of the device in a conventional manner and the second - preferably designed as a hole receptacle - in the area between these connection points Has connection means 42.
- first connection means 41 such as screw-type terminals or spring-type terminals
- the second connection means 42 are preferably spatially spaced from the first connection means 41 and are designed to be autonomous in their actuation or connection operation in such a way that when the first connection means 41 is wired, on the one hand the second connection means are freely accessible for further wiring and on the other hand for wiring of the second connection means 42, the first connection means 41 are not actuated (released and secured again).
- a contact element 6 designed as a plug contact serves in particular for contacting the second connection means 42.
- the corresponding contactor contact can be freely wired in a conventional manner by means of this connection element 6.
- dimensionally stable combined multiple plug contacts can also be preassembled, so that, for example, two adjacent contactors can be (pre) wired in a simple manner via dimensionally stable plug contact rows via the respective second connection means 42 in the form of a reversing circuit or a star-delta connection.
- Other applications such as the combination of a motor protection switch with one
- Contactors for a simple motor starter can be easily implemented with remotely positioned devices to be wired using pre-assembled multiple plug contacts that are connected via flexible free wiring. All of these applications can be wired in a particularly simple manner by the invention, without the standard connection point being "used up" or occupied in this way. In the case of further wiring, an already occupied connection point would not have to be loosened and further cables inserted and the connection point are secured again. This eliminates a common source of errors - connections that are already operational no longer have to be disconnected or additional cables have to be plugged in. In this way it is avoided that wiring that originally worked would become defective at once, perhaps because an already wired line It is also provided that the interface can also be used for a function check.
- FIG. 2a shows the two alternative embodiments of the contact contacts 4 of the contactor already shown in FIG. 1 with various first connection means 41 (screw-type or spring-type terminals) and a possible embodiment of the second connection means 42 in the form of a hole receptacle.
- first connection means 41 screw-type or spring-type terminals
- second connection means 42 in the form of a hole receptacle.
- other contacting or connection options are also conceivable, such as, for example, one or more groove-like recesses of the connection contact 4 or of the contact carrier (FIG. 2b) that are only on the edge.
- plug shapes as shown in FIGS. 4 and 5 are particularly suitable.
- the plug can advantageously be fixed in the hole receptacle via a non-positive or non-positive connection.
- the plug can have resilient projections projecting laterally from its contact body, which is in particular elongated and cuboid (Fig. 5).
- the plug contact it is also conceivable to design the plug contact as circular in cross section, so that it can be screwed into a correspondingly designed hole receptacle with its contacting body, which is likewise circular in cross section.
- the hole holder can be equipped with a finished thread or it can only be cut by screwing in the plug contact.
- Figure 3 shows the hole recording in an enlarged detail view.
- the hole receptacle is preferably designed in the form of a punched passage, so that contact tongue sections (8) directed upwards or downwards are formed around the hole receptacle, and this results in an enlargement of the contact area and thus an optimization of the contacting is ensured.
- FIG. 6 shows one half of a multi-pole circuit breaker.
- a connection contact 5, which is shown separately in FIG. 7, is mounted in a housing 2 for each switching pole.
- Each connection contact 5 carries a fixed contact 43 to the interior of the switching device, which interacts with an associated contact bridge, not shown.
- the connection contact 5 is in with a first connection means 41
- the first connection means 41 has a clamping screw 412, which is guided in a threaded bore 411 of the connection contact 5, and a clamping disk 413 mounted thereon. At least one first external electrical conductor can be connected via the first connection means 41. Beyond the threaded hole 411, ie closer to the outside of the circuit breaker, the connection contact 5 runs at a right angle to the front bent second connection means 52 in the form of a flat plug contact. A plug socket 7 in the form of a flat plug sleeve can be plugged onto this second connection means 52 in a non-positive and positive manner. The socket 7 is firmly connected to one end of a second external conductor 520.
- the second connection means 52 is formed in the center of the connection contact, ie it is in alignment with the axis
- the second connection means 52 is only so wide that first external conductors can be easily inserted into the clamping space of the first connection means 41 on both sides thereof. In this way, fork-like connecting elements can also advantageously be inserted into the terminal compartment, as are used in particular in three-phase busbar blocks.
