Definitions
- the invention relates to a device for connecting a first and a second electrical line with a plug element assigned to the first line and having a plug pin and with a plug element assigned to the second line and electrically contacting the plug pin in a pin receptacle.
- the plug and socket elements have to be fixed in an electrically contacting manner on the electrical lines assigned to them, which creates additional contact points which represent a potential source of interference, in particular under difficult operating conditions such as vibrations or aggressive atmospheres.
- constructive precautions must be taken so that both the plug and the socket element are safe to touch, particularly in the area of the contact points.
- the socket element is also time-consuming and costly to manufacture. From DE-GM 1 809 183 a device according to the preamble of claim 1 for the low currents in the field of electrical communication and measurement technology is known. The device is electrically connected to connecting lines by means of solder connections formed by the device, similarly to DE 20 41 065 B2.
- DE-GM 1 933 165 shows a one-piece contact spring with two spring halves which are punched out of a metal sheet and then folded together. The electrical connection to a connecting line also takes place via a soldering end formed by the contact spring.
- DE 79 15 670 U1 shows an electrical conductor track with a base area, to which at least one finger area, an intermediate coupling and a connecting part are connected.
- the invention is based on the problem of providing a device for plug-in connection which overcomes the disadvantages of the prior art and in particular has as few fault-prone contact points as possible and thereby guarantees protection against contact, in particular in the area of the contact points, despite simple manufacture.
- the socket element has a sheet metal strip forming the second line, which is shaped and in particular bent at its end transversely to its longitudinal direction to form the pin receptacle, that the plug pin can be inserted into the pin receptacle in the longitudinal direction of the metal strip.
- the second line and the socket element are made in one piece, and there is no contact point between the second line and the socket element.
- the pin receptacle has a right angle with the longitudinal axis of the sheet metal strip
- Cross-section has a shape which essentially corresponds to the corresponding cross-section of the plug pin.
- the connector pin is, for example, circular cylindrical and, like the pin receptacle, is designed for a current carrying capacity of 1 to 1000 A, preferably 50 to 200 A.
- the sheet metal strip is preferably made of copper or a copper alloy and preferably has a sheet thickness between 0.5 and 2 mm.
- the pin receptacle Due to the formation of the pin receptacle by bending the sheet metal strip transversely to its longitudinal direction, the pin receptacle has a high degree of flexural rigidity, in particular in the direction of insertion of the plug pin.
- the longitudinal direction of the sheet metal strip is essentially parallel to the direction of insertion of the plug pin and the sheet metal strip is at least partially bent around the central axis of the device in the area of the pin receptacle.
- the bushing element can be designed as a built-in socket which is fixed to a housing or is formed in one piece by it, and the opening on the housing which is to be provided for the sheet metal strip or the second line can be implemented in a simple manner.
- the sheet metal strip forms outside the bushing or
- a plurality of sheet metal strips, each of which forms a pin receptacle for a socket element can also form a layer of an overall multi-layer circuit board, the individual layers being electrically insulated from one another.
- the electrical and / or electronic components applied to the circuit board can be electrically connected to one or more of the layers and thus to one or more of the pin receptacles.
- the socket element is formed from two or more sheet metal strips increases the contact reliability and the current carrying capacity of the pin receptacle.
- the bending radius of the individual sheet metal strips is preferably essentially identical and in particular smaller than the radius of the plug pin. This advantageously results in at least two contact points or lines per sheet metal strip.
- the sheet metal strip in the area of the pin receptacle can have a plurality of point, line or area-like contact points which are preferably integrally formed in one piece and contact the plug pin.
- the at least two sheet metal strips are formed in one piece, there is no need for an electrical connection point which is fundamentally susceptible to faults.
- these can preferably be mechanically and optionally also electrically connected to one another outside the bushing area.
- This connection is preferably undetachable, for example by riveting, soldering, welding, in particular spot welding, or by flanging formed sheet metal tabs. It is of course also possible to screw, hook or latch the sheet metal strips.
- This enables an electrical connection of, for example, two sub-lines of the second line through the plug connection device. So much for the junction of the at least two metal strips only provides a mechanical connection, there is an electrical connection of the at least two metal strips when the plug element is inserted.
- the sheet metal strip or sheets in the area of the pin receptacle is or are comprised of a force-storing securing element, for example one or more clamping rings which exert a spring force in the radial direction on the sheet metal strips, further increases the contact reliability and current carrying capacity of the pin receptacle.
- a force-storing securing element for example one or more clamping rings which exert a spring force in the radial direction on the sheet metal strips
- the pin receptacle is arranged in a preferably electrically insulating socket housing, which overlaps the end of the pin receptacle leaving an opening for the passage of the plug pin, the socket element is safe to touch.
- the opening for the passage of the plug pin is preferably only slightly larger than the plug pin and its shape is adapted to the shape of the plug pin.
- the pin receptacle is arranged within the socket element and, in particular, set back so far relative to the opening that a test finger specified according to the safety regulations does not come into contact with the pin receptacle when it is inserted into the opening.
- the socket housing has locking means cooperating with the plug element
- the plug connection is simple and in particular can be produced without a special assembly tool, as a result of which the risk of unintentional contact with the plug pin and / or the pin receptacle is excluded.
- the connector pin is arranged in a connector housing projecting in the direction of insertion so that a test finger prescribed according to the safety regulations does not come into contact with the connector pin when inserted into the connector opening, the protection against contact is also with regard to the connector element
- the plug pin has an electrically insulating end section, which is preferably realized by an electrically insulating terminating element attached to the end of the plug pin.
- an electrically insulating terminating element attached to the end of the plug pin.

- the plug pin 4 is arranged in a plug housing 28 which projects beyond it in the plug direction 26.
- FIG. 2 shows a side view II-II of the device of FIG. 1.
- the locking lugs 32 Arranged on the socket element 12 on opposite sides with respect to the central axis 16 are two latching lugs 32 which, with latching tongues 34 integrally formed on the plug housing 28, enable a releasably latchable connection between the plug housing 28 and the socket element 12.
- the locking lugs 32 each have a run-on bevel 32a which, together with a chamfer 34a provided on the locking tongues 34, simplifies the engagement.
- the locking tongues 34 are formed in one piece with the plug housing 28 and can be actuated on their actuating lever 34b or pivotable about the articulation 34c formed in one piece with the plug housing 28.
- the pin receptacle 10 is arranged in a socket housing 36 and is gripped at the end thereof by leaving an opening 36 a for the passage of the plug pin 4.
