DE202004002078U1 - Universal in-line electrical connector has a bayonet contacts with threaded connection or push-in latched connection - Google Patents

Abstract

The in-line electrical connector has a cable plug [30] that has a screw threaded section [32] that engages the internal thread of the socket [10]. Internally the plug and socket have bayonet type connections. Alternatively the connection may be made using latching features [20] formed on the socket to engage the contacts.

Description

The invention relates to a connector, in particular an M12 device connector, with a housing, which is provided with a thread and a locking bead around one complementary connectors to be attached to the housing by thread engagement or snap-in.

Such a connector is out the German patent application 101 21 675 known. It enables to accommodate two different types of complementary connectors, namely for one a screw connector part that is on the thread of the connector can be screwed on, as well as a snap connector part can snap into place.

Based on this known state of the Technology, the invention has for its object the connector to further develop the above-mentioned to that greater flexibility with regard the complementary Connector is given, which is inserted into it and attached to it can be.

For this purpose, the invention provides that this casing has part of a bayonet lock. The invention is based on the knowledge that in addition to the well-known thread and the well-known locking bead on the housing Requirements for A bayonet lock can be created so that a third type of complementary connector can be easily attached to the connector, namely by means of a bayonet lock. This bayonet lock draws is characterized by the fact that it can be made faster than a threaded connection, however higher Offers holding forces as a snap connection.

It is preferably provided that the one provided on the housing Part of the bayonet lock consists of a groove that one insertion and has a holding section running approximately at right angles thereto. The introductory section can preferably narrow towards the holding section. This makes it easier the insertion of the complementary Connector if the bayonet lock is to be formed.

According to the preferred embodiment of the Invention is provided that casing a sleeve-like Has section on which the part of the bayonet lock provided on the housing is formed, with the locking bead on the outside of the sleeve-like Section is arranged. The locking bead can be attached to the housing Part of the bayonet lock at the transition between the insertion section and cut the holding portion without affecting the functionality of the bayonet lock is affected. The thread is preferably arranged in the interior of the sleeve-like section.

The invention is described below a preferred embodiment described in the attached Drawings is shown. In these show:

1 in an exploded view a connector according to a first embodiment with a complementary connector;

2 a partially sectioned side view of the connector of 1 with inserted complementary connector;

3 in an exploded view a connector according to a second embodiment with a complementary connector;

4 in a partially sectioned side view of the connector from 3 with inserted complementary connector;

5 in an exploded view a connector according to a third embodiment with a complementary connector;

6 in a partially sectioned side view of the connector from 5 with inserted complementary connector; and

7 in an enlarged view, section VII of 5 ,

In 1 is a connector 10 shown, which is designed here as an M12 device connector. It has a housing 12 by means of which it can be attached to a device. The housing 12 is with a sleeve-like section 14 provided of a contact block 16 surrounds. The sleeve-like section 14 is with an internal thread 18 provided, by means of which a first type of complementary connector on the housing 12 of the connector 10 can be locked. The sleeve-like section 14 is also with a locking bead 20 provided, which extends in the circumferential direction around the outer surface of the sleeve-shaped section 14 extends. Behind the locking bead 20 is a circumferential deepening 21 intended. Finally, on the outside of the sleeve-shaped section 14 a groove 22 trained, which is part of a bayonet lock. The groove 22 consists of an insertion section 24 (see also 7 ), which is generally along the longitudinal direction of the connector 10 extends, and one to the import section 24 approximately vertical holding section 26 , The insertion section narrows towards the holding section. The locking bead 20 is relative to the groove 22 so arranged that this approximately in the area of the transition from the import section 24 to the holding section 26 is cut.

Various types of complementary connectors can be attached to the connector described. In 1 is a complementary connector 30 shown the one threaded sleeve 32 has in the internal thread 18 of the connector 10 can be screwed in (see 2 ). In this way, the complementary connector 30 firmly on the connector 10 be locked.

In 3 is a complementary connector the 40 shown of a snap band 42 having. This engages with a circumferential projection 44 in the behind the locking bead 20 lying depression 21 a (see 4 ). On the outside of the snap band 42 is a locking sleeve 46 slidably arranged in the in 4 shown position prevents the locking collar 42 elastically expands and the complementary connector 40 from the connector 10 can be solved.

In 5 is a complementary connector 50 shown with a bayonet latch 52 is provided, which in the groove 22 on the outside of the sleeve-like section 14 of the connector 10 can intervene.

It can be seen that on a single type of connector 10 three different types of complementary connectors can be reliably locked. In practice, it is therefore no longer necessary to have different embodiments of connectors ready to be mounted on a device. Instead, the connector described can be attached, which can then be connected to the different types of complementary connectors. In this way, the storage and variety of variants is reduced.
