Description

The The invention relates to a two-part connector device with a first body and a second body the preamble of claim 1.

A connector device of this kind is made EP 0 570 650 as a detachable, electrical connector with contact pins in a first insulating body and mating associated contact sockets in a second insulating known. In the first insulating body, the contact pins are completely sunk in a blind hole. On the second insulating body, the contact bushes are laterally completely surrounded by a molded insulating jacket which completely fills the blind hole to the associated pin during assembly of the connector. Preferably, at least one circumferential groove or adapted at least one sealing groove is arranged on the outside of the insulating jacket and on the inside of the blind hole, such that when joining the connector, the sealing bead can engage in the associated groove.

at Such training may be under the action of a force, for example a tensile force, the connector unintentional or uncontrolled solved and disconnected, d. H. uncoupled. Depending on the application, there may be various disadvantages or damage occurs.

Of the Invention is based on the object, a connector device to provide the type mentioned, which avoids the disadvantages mentioned, in particular a secure, detachable connection of two Body allowed.

The The object is achieved by the training features of claim 1 solved. Further developments emerge the dependent claims.

• – Erstens ein Verschieben, d. h. Aufschieben, in axialer Richtung (Fügerichtung) und
• – Zweitens ein Verdrehen in Umfangsrichtung

beide sicher zusammengefügt werden. Dabei sind beide Körper formschlüssig in Eingriff. Insbesondere durch das Verdrehen in Umfangsrichtung ist eine sichere Verbindung geschaffen worden, die bei „bloßer" Einwirkung einer Kraft, beispielsweise einer Zugkraft, – bedingt durch den Formschluss – nicht lösbar ist. Vielmehr können erst durch bewusstes Einleiten der entsprechenden Gegenbewegungen bei Bedarf die beiden Körper kontrolliert wieder getrennt, d. h. abgekuppelt, werden.A first advantage is due to the fact that the connector device comprises two preferably substantially cylindrical body, preferably insulator, which by

• - First, a move, ie pushing, in the axial direction (joining direction) and
• - Second, a twisting in the circumferential direction

both are securely joined together. Both bodies are positively engaged. In particular, by twisting in the circumferential direction a secure connection has been created, which is not solvable in the "mere" action of a force, such as a tensile force, - due to the positive connection - Rather, only by deliberately initiating the corresponding countermovements if necessary, the two bodies controlled separately, ie uncoupled, be.

When second advantage can be listed that the first Body has circumferentially at least one sealing element against the one stop surface of the second body positioned when joining in the joining direction can be. As a result, the connector device (in the coupled Condition) against the ingress of moisture, for example water, Dirt, other impurities etc. safely protected.

Farther can be shown as a third advantage that at least one the body, preferably both bodies, circumferentially at least each have a recessed grip. Preferred may the recessed grips diametrically opposite, d. H. in the circumferential direction arranged on each body offset by 180 ° be. This allows the connector manually with little effort or assembled or solved by means of tools become.

One fourth advantage is that the connector device relatively simple, preferably made of an electrically non-conductive Material, is formed and with little effort, for example made of plastic by injection molding, can be produced.

The Invention is intended to be closer to an embodiment be explained. Here are shown schematically:

1 a connector device having substantially the first body,

2 the second body of the connector device in side view,

3 a front view of 2 ,

The connector device comprises a first and a second body 1 . 2 , where the first body 1 preferably a centrally arranged contact socket 4 and the second body 2 preferably a centrally arranged contact pin 3 exhibit. Contact socket 4 and contact pin 3 are on the line side at one end, each with a corresponding cable 12 connected and are in the assembled state of the body 1 . 2 in contactable engagement. The body 1 . 2 each carry a screw cap at these ends 15 for fixing the cables 12 , Furthermore, the body can 1 . 2 Strain reliefs for the inserted cables 12 exhibit. The body 1 . 2 are preferably insulating body and made of a plastic. 1 essentially shows the first body 1 , where the second body 2 in assembled position of body 1 . 2 is merely indicated for the sake of clarity.

The first body 1 has a waistband at the free end 5 and this covenant 5 has at least one substantially angled guide 6 ; 6.1 . 6.2 on. The second body 2 has at its free end on an inner wall 13 at least one guide element 10 on.

In assembled position, the inner wall surrounds 13 (Body 2 ) the covenant 5 (Body 1 ) and the guide element 10 and the leadership 6 ; 6.1 . 6.2 form a positive connection.

The leadership 6 at the federal government 5 is essentially in the axial direction of the first body 1 by means of a longitudinal guide 6.1 and in addition to an circumferentially angled circumferential guide 6.2 educated.

The relative position of the axis of the longitudinal guide 6.1 crosses the axis of the first body 1 at an acute angle. The relative position of the axis of the circumferential guide 6.2 crosses the axis of the first body 1 preferably at substantially right angles. In this case, the longitudinal guide 6.1 straight or as in 1 shown curved on the waistband 5 be arranged. At its end, the circumferential guide 6.2 for the guide element 10 a lock 7 , For example, a recess, have. The longitudinal guide 6.1 starts at the free end of the covenant 5 ,

The guide element 10 may be in simple training ever a bolt, a pin or a nose, etc., on the inner wall 13 are arranged and in assembled position the body 1 . 2 with the leadership 6 ; 6.1 . 6.2 passably engaged (positive connection). In a development, the guide element 10 the wall thickness of the second body 2 penetrate, as in 3 is shown.

In another training, the body can 1 several circumferentially offset guides arranged 6 ; 6.1 . 6.2 exhibit and the body 2 has correspondingly more on the inner wall 13 circumferentially offset arranged guide elements 10 on.

3 shows an example of training with two diametrically offset by 180 ° arranged guide elements 10 ,

The Bund 5 of the first body 1 carries at least one sealing element 8th and the inner wall 13 of the second body 2 has an inside stop surface 11 on. Each sealing element 8th can in a circumferentially arranged groove of the Federal 5 be included. Preferably, the federal government 5 one on the body 1 arranged positioning surface 16 for a sealing element 8th on.

In training according to 1 are two sealing elements 8th parallel on the waistband 5 of the body 1 arranged. This is the first sealing element 8th at the positioning surface 16 on and on the second sealing element 8th lies in the assembled position of the two bodies 1 . 2 the stop surface 11 at. The stop surface 11 surrounds the waistband 5 and is against the second sealing element 8th adjoining positionable.

In a first training is the leadership 6 ; 6.1 . 6.2 in the wall thickness of the covenant 5 integrated as a groove. In a second training, the leadership 6 ; 6.1 . 6.2 the wall thickness of the covenant 5 penetrate, ie the leadership 6 ; 6.1 . 6.2 is designed as a slot and the guide element 10 grabs the slot.

The Bund 5 , the inner wall 13 and the stop surface 11 are adapted to each other. Preference is given to waistband 5 , Inner wall 13 and stop surface 11 as well as the sealing elements 8th each cylindrical.

At least one of the bodies 1 or 2 , preferably both bodies 1 . 2 , can circumferentially at least one recessed grip 9 exhibit. Preferably, the recessed grips 9 lying diametrically opposite, ie offset in the circumferential direction, for example, each 180 °, on each body 1 . 2 be arranged. As a result, the connector can be assembled or released manually or by means of tools with little effort.

The mode of action is as follows. For example, the second body 2 in joining direction 14 on the first body 1 postponed. A guide element 10 engages at the beginning of the covenant 5 in the longitudinal guide 6.1 (the leadership 6 ) and is further displaced in the axial direction. The leadership 6 Angled, the circumferential guidance 6.2 starts and the second body 2 is in the circumferential direction (the circumferential guide 6.2 following) until reaching the end position, for example, the lock 7 , twisted. Both are bodies 1 . 2 securely assembled to a connector device and remain positively engaged.

By initiating the corresponding countermovements, if necessary, the two bodies 1 . 2 be separated again, ie uncoupled.
