Description

The invention relates to a connector, in particular for connecting electrical cables and / or electrical components in sanitary engineering via a second connector. The connector has an electrically conductive male contact and an electrically conductive female contact.

The connector may be used to interconnect electrical cables with each other or a cable with an electrical component or two electrical components. For this purpose, a correspondingly designed second connector can be used in particular with the same contour.

When used in sanitary engineering special measures with regard to waterproofness are required. For example, the connector may be used to connect a cable to an electromagnetic fluid valve. Here, a connector is attached to the cable and a connector with the electrical component, so that then the two connectors can be connected to each other by plugging.

The fact that the connector has a male contact and a female contact, the connection is reverse polarity, since each of the male contact of a connector is inserted into the female contact of the other connector.

The invention has for its object to simplify the handling of a connector.

The invention solves the problem with the features of claim 1. Advantageous developments are part of the dependent claims.

In the connector according to the invention, the male contact and the female contact are arranged side by side in an electrically insulating housing. This eliminates the otherwise necessary during assembly isolation measures that would have to be done after connecting the connector. In addition, the connectors are thus well protected against external influences. This is particularly advantageous for connections in sanitary engineering.

Preferably, a first portion of the housing forms a mechanical connector and a second portion of the housing a mechanical socket, wherein the mechanical connector and the mechanical jack are configured and arranged such that the mechanical connector in the mechanical socket of a second, identical connector can be inserted. As a result, the handling can be facilitated during assembly, since the fitter can connect the polarity reversal in a simple manner with each other without visual contact, the two connectors.

Preferably, the male contact is arranged in the mechanical socket, wherein the female contact can be arranged in the mechanical connector. Through this sequence, a special tightness of the plug can be achieved.

In particular, in the case in which the connector is to be used in sanitary engineering, sealing means for sealing between the mechanical socket and the mechanical connector of a second, identical connector in the inserted state are useful. This can prevent liquids from getting into the connector.

The sealing means may comprise at least one outer bulge of the mechanical connector and / or an inner bulge of the mechanical socket. As a result, in the inserted state, a clamping between the mechanical connector and the mechanical socket can be achieved, which can serve as a seal at the same time as a seal. Preferably, the bulge extends annular, in particular rib-shaped, around the mechanical connector. About the number of bulges of the degree of sealing can be increased. By means of three sealing ribs already a good tightness can be achieved.

In order to further increase the safety when handling the connector, in particular with regard to the polarity reversal, the end face of the mechanical connector and the end face of the mechanical socket can be offset from each other, in particular by at least 1 mm, preferably at least 2 mm.

The front side of the mechanical connector and the front side of the mechanical socket can lie in different planes, which in particular have a distance of at least 1 mm, preferably at least 2 mm.

In this way it can be achieved that the short-circuit safety is increased when the connector comes into contact with the front side, for example with a conductive object or a conductive liquid.

The security can be further increased by the fact that the contacts are completely in the housing. In particular, the male contact can be completely in the mechanical socket. Furthermore, the female contact may be completely in the mechanical connector.

The handling can also be facilitated by the fact that the housing has a grip area with indentations and / or bulges. By the inputs and / or bulges the grip can be increased.

The handling can be further improved by the housing having a gripping area with two parallel, planar side walls which are connected to one another via curved side walls. By this flattening of the housing can be improved by feeling the connector without visual contact necessary for the preparation of the connector orientation of the connector. Furthermore, a logo or other labels can be arranged on one or both of the flat side walls.

An advantageous embodiment of the invention will be described with reference to 1 to 5 described. Show it:

1 a connector on a cable in a perspective view;

2 the connector after 1 in a plan view;

3 the connector after 1 in a side view;

4 a section of the connector after 1 in a sectional view; and

5 the connector after 1 in a front view.

The 1 to 5 show a reverse polarity protected electrical connector 1 that stuck with a cable 2 connected with twin strand. Other shapes such as round cables or single stranded wires can also be connected. The connector 1 with the housing 3 has a grip area A and a plug-in area B.

In grip area A, the connector points 1 on the housing 3 indentations 11 so that the connector can be well connected to or disconnected from a second connector. The grip area A also has two plane parallel side walls 14 on, according to 5 over two curved side walls 13 connected to each other. The flat side walls 14 can be used to apply a company logo or other lettering 17 serve. Furthermore, by this configuration of the handle portion A, the orientation of the connector 1 before connecting to a second connector 1 be simplified.

In the plug-in area B, the housing has 3 of the connector 1 a mechanical socket and an adjacent mechanical connector 4 on. The mechanical socket 5 and the mechanical connector 4 are configured and arranged so that they are identical to a second connector 1 can be connected. Here is the mechanical connector 4 a connector 1 in the mechanical socket 5 of the second connector 1 plugged in.

For the preparation of the electrical connection, the two-pole connector 1 according to 4 electrically conductive contacts 6 and 7 on. The electrical connector contact 7 is designed as a pin connector, which in a closed sleeve as an electrical socket contact 6 is pluggable.

The plug contact 7 is completely inside the mechanical socket 5 arranged. The electrical socket contact 6 is completely inside the mechanical connector 4 arranged. Because both contacts 6 and 7 completely in the case 3 Safety can be increased.

In the connected state of two connectors 1 is in each case the electrical plug contact 7 in the electrical socket contact 6 the other connector 1 plugged in. The plug contact 7 has a rejuvenation at its end 10 on, in a simple way in a widening 9 of the electrical socket contact 6 is insertable.

Inside the case 3 , which may be made of electrically insulating plastic, for example, are connecting elements 12 arranged that the electrical contacts 6 and 7 with the cable 2 connect.

In the connected state of two connectors are two different types of connectors, namely a mechanical connector and an electrical connector.

To achieve a sufficient tightness against, for example, liquids, the mechanical connector 4 three rib-shaped bulges 8th on, in the connected state of two connectors 1 thus between the mechanical socket 5 and the mechanical connector 4 lie. Through the ring around the center axis M of the mechanical connector 4 extending bulges 8th becomes a press fit between mechanical connector 4 and mechanical socket 5 reached. About the three annular sealing ribs 8th Thus, a radial seal between the mechanical socket takes place 5 and the mechanical connector 4 ,

The face 15 the mechanical socket 5 is opposite the face 16 of the mechanical connector 4 arranged offset by at least 1 mm. The face 15 which lies in the plane E and the end face 16 , which lies in the plane F, have a distance d of at least 1 mm. As a result, the security can be increased. The short-circuit safety is further increased by the fact that the electrical contacts 6 and 7 with their free ends 9 and 10 staggered against each other.

The electrical connector 1 is reverse polarity protected because it connects to a second connector 1 only in one way is possible. Because of the connector 1 with a second, identical connector 1 is connectable, also creates a logistics advantage, since no distinction is made between separate connector parts and socket parts. Due to the reverse polarity protection, a uniform cable color can also be used.

The connector according to the invention 1 can z. B. on cables 2 or electrical components, in particular solenoid valves are arranged.
