Description

The present invention relates to an electrical connection element with an integrated fastening element for fastening the connection element on or on a support, in particular a mounting wall or the like.

State of the art

In the prior art, different fastening means and fasteners, in particular cable clamps or the like, are known.

From the DE 100 06 211 A1 is a molding, encapsulated electronic component is known, which is embedded in a molded body, which consists of a solid, thermoplastic, processed under low pressure conditions hotmelt molding compound based on polyamide and on which at least one locking lug is integrally formed.

From the DE 196 49 780 A1 a waterproof cable connector for use in the area of excessive ambient temperatures is known, with a split guide body with insertion side integrated sealing elements, wherein the free space is filled by an injection-moldable plastic compound.

From the DE 197 37 909 A1 a device for fastening a push-button switch with a housing is known, wherein a fastening member is provided with a pin and facing away from the housing end of the pin one or more spring elements extending toward the housing.

From the US 2009/0307883 A1 is a holding element with a fastening body known from the side lugs extend away.

From the US 2005/0242247 A1 Cable holding devices are known which have a retaining pin for insertion into a retaining plate, wherein the retaining pin has fir-tree-like retaining elements.

From the DE 92 17 344 U1 is a branch connection for electrical. Cables with a contact element known, wherein on the contact element crimp connecting means are formed for a line to be picked off.

The DE 41 10 769 A1 discloses a connection means with a two-piece plastic body for the attachment of mostly flat bodies with different dimensions for extremely flat fasteners.

The field of application of this connection clamps is preferably in electrical or telecommunications equipment.

The DE 100 11 552 A1 discloses another fastening system for mounting electrical wires, especially cables.

To fix the cable, a cable with a suitable cross-section is received in a receiving space formed between the cable clamp and the housing wall. In this case, the cable, but not the cable-mounted connection element is mounted directly on the wall directly.

The DE 36 24 993 A1 discloses a fastener for wall mounting installation material. Such a wall mounting can be done in different ways. In addition to a holding member, which serves to receive the installation material, the known fastening element additionally has a receiving plate for connection to a web feed nailer.

A disadvantage of the known fasteners that this directly the cable and not the connecting element, such. B. a connector, which is mounted on the cable set. For this purpose, each connecting element additionally requires a cable clamp, so that in a train on the cable, the cable does not slip out of its mounted position of the connecting element.

A further disadvantage of the known fastening elements is that prior to or at the same time a wall mounting of the installation material must first be done on the wall, so that the use of the known fasteners is regular, time-consuming and correspondingly costly.

Object of the present invention

The invention is based on the technical problem of generally being able to fasten a connecting element and especially a plug connector independently of external and additional fastening devices to a mounting carrier, in particular a mounting wall.

This task should be solved on the condition that no additional mounting material is needed and special tools are unnecessary. It should therefore be provided as simple as possible to be mounted solution.

Technical solution

This technical problem is solved according to the invention with an electrical connection element according to claim 1.

In one embodiment, an electrical connector is provided integrally with a fastener, preferably with an integral dowel-like attachment pin.

In one embodiment, a fastening pin is formed with radially encircling lamellar spring elements, which are laterally flattened in a particularly advantageous embodiment.

The inventive design, the electrical connection element or the fastening part according to the invention, such. As a Y-housing, are anchored by means of the mounting pin in a simple manner in a borehole and put under tension by means of the spring blades. Alternatively, the fixing pin can be inserted directly into a mounting hole and fixed to this.

Connecting elements according to the present invention relate to all cable-side connecting elements, in which a cable is either connected directly to contacts for plug-in mounting or in the cable directly to each other or their free cable ends are to be brought into electrical contact.

A typical example of a cable connection of several cables is a Y-distributor, in which a cable input is converted on one side into a two-sided cable outlet.

As an alternative to a single fastening pin, mutually spaced, a plurality of identically formed fastening pins can be integrated on the connector.

An embodiment of a connector according to the invention with integrated fastener is shown in the following drawings and explained in more detail. Show it:

1 a perspective view of a first connector (Y-distributor) with an integrated fastener;

2 a side view of the Y-distributor, according to 1 ,

1 shows a perspective view of an electrical connection element 1 in which the electrical connection element 1 as Y-distributor 2 is trained. The Y-distributor 2 includes a housing 3 , The Y-distributor is designed so that a cable input 15 and two cable outlets 20a . 20b are provided. The housing consists of a housing lower part 4 and an upper housing part 5 , preferably designed as a plastic housing. The lower housing part 4 is with the upper housing part 5 by means of locking means 6 releasably connected.

This ensures that the electrical connection element 1 can be opened in the assembled state and a mounting connection within the housing can be performed at any time.

Advantageous is the housing 3 formed as a one-sided circumferentially sealed housing.

The cable glands 7 are also advantageous as sealed cable outlets for cables 8th educated. For mounting the cables 8th through the cable glands 7 passed through and by means of suitable connection technology inside the housing 3 electrically brought into contact with each other.

The fastening element according to the invention 9 is integral to the housing base 4 arranged. Unless the case 3 was produced as a plastic molding by injection molding process, the fastener can in a single injection process 9 integral with the lower housing part 4 be formed.

Advantageously, this can also be done in the 2-component injection molding process, since then the mechanical properties of the fastener 9 can be customized according to the requirements. The fastener 9 is in a preferred embodiment, as in 1 and 2 shown, designed as a fastening pin. At the attachment pin is at the end of an insertion 11 , which is tapered with a mushroom-shaped hat for better insertion into a mounting hole.

The fixing pin 9 is preferably arranged as a substantially cylindrical pin formed on one of the side surface via a laterally flattened attachment portion 12 features.

All around the attachment pin 9 are slats 10 educated. The slats 10 are as spring plates substantially as a plurality of juxtaposed spaced apart spring blades 10 educated. The spring blades 10 can in a separate injection molding process from one of the mounting pin 9 different material to be molded on this.

The Y-distributor 2 can also be designed as a connector.
