In the figures, identical or equivalent components are marked with the same reference characters.

FIGS. 1 a to 1 e show a plug connector 1, which consists predominantly of a printed-circuit housing 2 with corresponding add-on parts or built-in parts, which are partly formed integrally with the printed-circuit housing 2.

The side of the interface connector 1 lying on the top in FIG. 1a serves for connection to a printed circuit board, wherein a support surface 3 of the printed circuit board

Interface housing 2 in a mounted position plan to rest flat on the circuit board.

On the opposite side of the interface connector 1, according to FIG. 1b, a plug connection 4 is integrally formed on the interface housing 2, in which a plug 50 according to FIGS. 2a to 2c can be accommodated for electrical connection of the plug 50 to the circuit board. For electrical contacting of electrical connections of the circuit board with the plug 50 are two through the interface connector. 1

extending, in particular straight, contacts 6, 6 'provided. The contacts 6, 6 'extend in an insertion direction S and protrude

pcb side a support plane formed by the support surface 3. On the other hand, the contacts 6, 6 'end within a receiving space 14 of the plug connection 4. The contacts 6, 6' are held in the interface housing 2 in a clamping manner by passage openings 15, 15 'shown in cross-section in FIG.

The plug 50 has a connector 4 corresponding to the connector

contoured mating face 52 with two plug contacts 53, 53 'for

electrical contacting of the contacts 6, 6 '. The plug contacts 53, 53 'are formed as contact springs. Furthermore, the plug 50

oppositely arranged latching arms 54, 54 'for latching with

corresponding latching arms 16, 16 'of the interface connector 1. The latching arms 54, 54 'are arranged in the receiving space 14.

For sealing the interface connector 1, in particular the

Plug connection 4, is provided on the plug 50, in particular on the mating face 52, a sealing lips 51, 51 'exhibiting sealing ring 55, wherein the sealing lips 51, 51' are arranged on the inner circumference of the sealing ring in the circumferential direction parallel to each other, namely transversely to

Plug-in direction S. The sealing lips 51, 51 'are in the assembled state of the plug 50 on the interface connector 1 on an outer periphery 13a of a peripheral wall 13 of the connector terminal 4. A reverse arrangement, that is, on the outer periphery 13a of the peripheral wall 13 arranged sealing lips, the invention conceivable. For latching and electrical connection of the interface connector 1 to the circuit board locking means 7, 8, 8 'are arranged in the form of locking arms on the opposite side to the connector 4, wherein the locking arms extend in the insertion direction S. The latching means 7 extends from a side edge 17 of the interface housing 2 of the support surface 3 in

Plug-in direction S. The latching means 7 is formed integrally with the interface housing 2. The locking means 7 has an outward, ie transversely to

Plug-in direction S from the side edge 17 outwardly projecting locking lug 7r, which for locking with a corresponding recess of the

PCB serves. The locking lug 7r accordingly points away from the contacts 6, 6 '.

On the opposite side of the contacts 6, 6 'to the locking means 7, the locking means 8, 8' are arranged in the form of two latching arms, both in

Plug-in direction S run. The locking means 8, 8 'each have latching lugs 8r, 8r', which are approximately at a center or in

Plug direction S extending longitudinal central axis of the interface housing 2 point. Thus, the locking lugs 7r, 8r, 8r 'all in different directions, but in particular to one side of the interface connector 1, and thus provide a secure locking forth.

The latching means 8, 8 'are arranged in a function space 5 surrounded by the support surface 3, while - as described above - the

Detent means 7 protrudes from the support surface 3 on the side edge 17.

The functional space 5 is delimited laterally by a peripheral shoulder 18 which at the same time delimits the bearing surface 3 with respect to the functional space 5.

The support surface 3 extends from the paragraph 18 to a

Outer edge 3a of the support surface. 3 In the functional space 5, a seal 9 is further provided which has two recesses 19, 19 'for the latching means 8, 8'. Furthermore, the seal 9 has a passage opening 11 for the passage of the contacts 6, 6 '.

The seal 9 furthermore has a sealing surface 10 arranged parallel to the bearing surface 3, which protrudes in the plug-in direction S in the non-mounted state relative to the bearing surface 3.

When mounting the seal 9 is compressed until the locking means 7, 8, 8 'engage in corresponding locking receptacles of the circuit board and the sealing surface 10 is aligned with the support surface 3.

During the compression of the seal 9, a circumferential compression gap 12 provided in the unassembled state between the shoulder 18 and the seal 9 is filled by the seal, wherein the volume of the seal 9 is dimensioned so that the seal 9 in the assembled state of the interface connector. 1 the compression gap 12 as completely as possible fills. At the same time, when compressing the

Seal 9 during assembly and the through hole 11 and the

Recesses 19, 19 'smaller.

It can be seen very well that in relation to the size of the interface connector 1 very large, effective sealing surface, which must consist not only of the sealing surface 10, but also from the opposite surface of the seal 9 and the side circumference of the seal 9, if they rests on the shoulder 18, an effective and safe sealing effect

guaranteed. The seal 9 has the additional function of protecting the locking means 8, 8 'and the contacts 6, 6' and also serves to dampen vibrations. There will be a very high density not only between the Plug and the interface connector 1, but also achieved between the interface connector 1 and the circuit board.

Due to the straight plug geometry, the plug 50 can be mounted simultaneously with the interface plug 1 and the printed circuit board in a continuous movement in the insertion direction S, so that the assembly of the plug 50 with the interface connector 1 and the circuit board is very simple. At the outer edge 3a and its plump support on the circuit board is also immediately recognizable whether the interface connector 1 has been properly mounted.
