Description

The invention relates to a connector according to the preamble of claim 1 and an arrangement for electrically connecting two electrical devices by means of such a connector according to claim 8.

In the automotive industry, it has been customary for quite some time to integrate control devices for the engine or transmission into the motor vehicle assembly to be controlled, that is to say the engine or transmission. Above all, the gearbox control units form a very compact unit as a local control unit. Compared to the conventional use of external ECUs, this arrangement has enormous advantages in terms of quality, cost, weight and functionality. In particular, this results in a significant reduction of connectors and cables.

The integration of the control unit in the transmission makes high demands on its thermal and mechanical strength. The functionality must be guaranteed over a wide temperature range (about -40 ° C to 150 ° C) as well as mechanical vibrations (up to about 40g). Since the control unit is surrounded by transmission oil, it must also be media-tight, in particular oil-tight.

1. a) Sensorcluster und ECU als eine Einheit in einem Steuergerät integriert sind, oder
2. b) bei beiden Geräten männliche Stecker herausgehen, die mit einem Kabelbaum verbunden werden, an deren Enden jeweils ein weiblicher Stecker angebracht ist.

When two electrical devices with housing, in particular a control unit (ECU) and a sensor cluster unit, are to be electrically connected to each other on site, both housing having laxative male connectors, this usually happens by

1. a) sensor cluster and ECU are integrated as a unit in a control unit, or
2. b) go out on both devices male connector, which are connected to a harness, at the ends of each a female connector is attached.

The above standard is not a solution if a control unit is to be plugged directly into a sensor cluster and no additional wiring harness is to be used. Another problem is the additional tolerances caused by the connection, for example screwing the ECU to the sensor cluster.

The ECU and sensor cluster are to be electrically connected without integrating both devices into a common controller and without using a wiring harness.

Integrated controllers have the disadvantage that the entire electronics are exposed to difficult environmental conditions, especially high temperatures.

Connection with a wiring harness has the disadvantage that the wiring harness has additional space and is sometimes accessible in the vehicle.

The additional plug-in tolerances are to be overcome, which are caused by the screwing of ECU on the sensor cluster.

It is therefore an object of the present invention to provide a connector that reliably removably electrically connects two male connectors with tolerance compensation.

As a result, in particular manufacturing tolerances can be absorbed in these dimensions.

In a connector according to claim 3, the contact spring unit consists of a rod-shaped, elastically deformable spring connection, wherein in each case at the end of the spring connection, a contact opening is arranged. Each contact opening is arranged in a separate block, wherein the blocks in the region of the center of the spring connection to each other an axial distance, in particular in the range of at least 2.0 mm, and to the inside of the Housing have a radial distance, in particular in the range of 0.5 - 1.0 mm. As a result, advantageously additional manufacturing tolerances can be absorbed.

As a result, when guiding the two plugs, in particular, a directed guidance during compression of the contact spring unit is ensured.

In a connector according to claim 5, the locking pin is arranged circumferentially at the contact opening. Likewise, the locking lug in the associated block is arranged circumferentially. This ensures in particular when producing the connection between the two male connectors and the connector, the locking pin rests securely on the latching lug.

In a connector according to claim 6, the connector and the connector are locked together in the established connection between the two male connectors and the connector. For this purpose, mutually matched locking devices are provided on the individual parts.

In a connector according to claim 7, the plug are sealed against each other when established connection between the two male connectors and the connector. Advantageously, the seals are designed as separate Einlegdichtungen or molded onto one or both plugs.

Another object of the invention is to electrically connect two electrical devices, each with a male connector with tolerance compensation with each other.

This further object is achieved by an arrangement with the features of claim 8.
