Other embodiments and many of the advantages mentioned become apparent in view of the drawings. The elements shown in the drawings are not necessarily shown true to scale in relation to one another.

(11) In the figures of the drawing, identical, functionally identical and identically acting elements, features and components are respectively provided with the same reference symbolsunless stated otherwise.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

(12) The drawings are described below in an interrelated and comprehensive manner.

(13) FIG. 1 shows a perspective view of an electrical connector 100 according to the invention during closing. The connectors 100 has a first connector portion 101, a second connector portion 201 and a locking mechanism (107, 109, 207).

(14) The first connector portion 101 can be mounted, for example, on a printed circuit board. The second connector portion has a printed circuit board 209 which serves as a data memory. For the purpose of power and data transmission between the two connector portions 101, 201, said connector portions have contact elements 103, 203.

(15) The connector 100 is of self-locating design. For this purpose, the connector portions 101, 201 each have a magnet 105, 205.

(16) In FIG. 1, the connector is closed in direction ()z. However, the connector cannot be opened in direction +z.

(17) FIG. 2 shows an electrical connectors 100 according to FIG. 1 in a closed state. Said FIG. 2 shows that the electrical connectors 100 has a particularly compact form and also a homogeneous geometry. Therefore, only the housings 115, 215 of the two connector portions 101, 201 and also possible printed circuit board or cable connections of the connector portions are accessible in the closed state. The smooth, planar condition prevents dirt or germs accumulating on the surface of the connector. In addition, the connector is particularly easy to clean and to sterilize. Therefore, the compact form is particularly advantageous in respect of hygiene.

(18) In FIG. 2, the second connector portion 201 can be connected to a cable by means of a cable connection (not illustrated) for power and data transmission.

(19) FIG. 3 illustrates the first connector portion 101a in a diagrammatic perspective view. The connector portion 101a comprises an electrical contact element 103 with a plurality of stamped contact strips 111. A magnet 105 (not illustrated) is located beneath the contact element 103 and is concealed by it.

(20) The connector portion 101a in FIG. 3 comprises a locking element 107a which is of substantially rigid design. The locking element 107 has a groove 117 through which a latching element of a second connector portion can be pushed out (and pushed in). FIG. 3 shows that the locking element 107a is bounded by a recess of the housing 115. The boundary lends the locking element 107a a degree of rigidity and prevents expansion of the locking element 107a. The locking element 107a has beveled side faces 119 at its top side. Owing to an action of force or pressure from above, the beveled side faces give way downward to a certain extent. The side faces on the inner side of the groove 117 are of right-angled design in such a way that a latching element of a second connector portion tilts with the locking element 107a when pulled from above or in the z-direction.

(21) Furthermore, the connector portion 101a in FIG. 3 has a plurality of guide elements 113. The guide elements 113 guide the first and, respectively, the second connector portion during opening of the connectors. Therefore, the guide elements 113 prevent tilting during opening of the second connector portion in the locking element 117 by virtue of the latching element of the second connector portion being guided laterally or in the y-direction out of the locking element 107a owing to an action of force by the guide elements 113 during opening.

(22) FIG. 4 shows the connector 100 during opening by way of a user moving the first connector portion 101 in the Y-direction, away from the second connector portion 201.

(23) FIGS. 5 and 6 each show a second connector portion 201a, b with electrical contact elements 203. In FIG. 5, the electrical contact elements 203 are designed as contact pins 211. In FIG. 6, the electrical contact element 203 are designed as stamped, bent contacts 212. A C-shaped latching element 207a is formed around the contact elements 211, 212. A semicircular magnet 205 is arranged beneath the latching element 207a.

(24) It has already been explained above with reference to FIG. 3 that the locking element 107a of the connector portion 101a in FIG. 3 is of substantially rigid design. Accordingly, the C-shaped latching element 207a can be deformed in a spring-elastic manner the way the a connection can be established not only by laterally inserting the second connector portion into the first connector portion, but rather also by said connector portions being plug-connected from above or below. For this purpose, the C-shaped latching element 207a is sprung at the rear in such a way that it can deform inward owing to an action of force from above. Therefore, the latching element 207a forms a spring.

(25) Springing of the latching element 207a at the rear is not illustrated in FIGS. 5 and 6. Expedient springing at the rear can be performed by a flexible fastening in front of a hollow space or, for example, in front of a compressible elastomeric foam.

(26) In order to facilitate plug-connection of the connector, the latching element 207a has beveled surfaces at its top side which is directed toward the interface. In order to prevent a connector from being released on account of being pulled, the latching element 207a is of right-angled design at its bottom side.

(27) The two connector portions 201a, b are compatible with a first connector portion 101a, for example according to FIG. 3. Accordingly, the connector portions 201a, b have guide elements 213 which correspond to the guide elements 113.

(28) It goes without saying that the selection of contact elements is not restricted to a specific embodiment according to the invention or to the first or second connector portion, but rather can be combined in any desired manner.

(29) FIGS. 7 and 8 show a further alternative embodiment of the present invention. A first connector portion 101c and also a second connector portion 201b are illustrated in each of FIGS. 7 and 8. The connector portions 101c and 201c differ from the connector portions 101a, 201a owing to their latching element 207c and locking element 107c.

(30) FIGS. 7 and 8 show that the locking element 107c is partially arranged in a recess 119. Therefore, the locking element 107c can expand owing to an action of force from above by the latching element 207c during the process of plug-connecting the connector. In order to facilitate expansion of the locking element 107c, the locking element 107c and also the latching element 207c have beveled surfaces on their top side.

(31) Owing to the adequate spring-elastic properties of the locking element 107c, the latching element 207c is of substantially rigid design and designed without spring-elastic properties.

(32) In FIGS. 7 and 8, the locking element 107c has a C-shaped main structure. Further elements which are in the form of an arc of a circle are arranged on the inside of the C-shaped main structure. Even though this is not illustrated in the figures, it is conceivable to provide the elements which are in the form of an arc of a circle with springs from behind, similarly to the manner which has been described in FIGS. 5 and 6 with respect to the C-shaped latching element 207a.

(33) FIG. 7 additionally shows that the semicircular magnet 205 is strengthened by a magnetic disk 206.

(34) Although the present invention has been fully described above with reference to preferred exemplary embodiments, it is not limited thereto but rather can be modified in a variety of ways.
