Description

BRACKET FOR FIXING A CONNECTOR ON AN ELECTRICAL BUSHING

The present invention relates to a bracket for fixing a connector to an electrical bushing, as well as an assembly comprising a connector, an electrical bushing and such a bracket.

PRIOR ART

The attachment of a connector to an electrical bushing is often carried out using a stirrup which has two legs. At one of the ends of each leg is made a hook which is fixed in a hooking hole provided on the electrical crossing.

The other two ends of the legs are connected by a crossbar which comes by compression above the connector in order to lock it on the electrical bushing.

Although such a stirrup is generally satisfactory, it happens that the legs are too rigid which makes it all the more difficult to lock the crossbar.

It is therefore necessary to find a solution that increases the elasticity of the stirrup while maintaining a sufficient level of tightening force.

An object of the present invention is to provide a bracket for fixing a connector on an electrical bushing which has a large mounting range.

To this end, a bracket is proposed for fixing a connector having an upper surface on an electrical bushing comprising hooking holes, said bracket being made of a wire and comprising:

- two legs, where one of the ends of each leg is provided with a hook intended to be introduced into a hooking hole, and

- a crossbar connecting the other two ends of the legs together, where said crossbar is provided to bear against the upper surface,

where each leg comprises a winding of the wire constituting it and extending over at least one turn.

With such an arrangement, the two windings constitute reserves of elasticity which facilitate the locking of the yoke on the connector.

According to a particular embodiment, each winding is at the junction between a leg and the crossbar.

According to a particular embodiment, each winding is along one leg.

According to a particular embodiment, the crossbar has a V-shaped bend, the point of which is provided to lodge in a recess in the upper surface.

According to a particular embodiment, the crossbar has a U-shaped fold, the bottom of which is intended to be clamped by any suitable means provided at the level of the upper surface.

According to a particular embodiment, the crossbar of the stirrup takes the form of an arc of a circle intended to be positioned on a part of a cylindrical shoulder of the upper surface.

The invention also proposes an assembly comprising a connector having an upper surface, an electrical bushing comprising hooking orifices and a bracket according to one of the preceding variants.

The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the attached drawings, among which:

is a side view of an assembly according to the invention with an angled connector and a bracket in the free position,

DETAILED DESCRIPTION OF EMBODIMENTS

Figs. 1 to 3 show an assembly 100 according to one embodiment of the invention which comprises a connector 102 which here is an angled connector, an electrical bushing 104 to which the connector 102 is connected, and a yoke 106.

The stirrup 106 consists of a rigid wire, such as a metal wire and more particularly a stainless steel wire of 2 to 3 mm in diameter for example. Preferably, the material constituting the metal wire has spring properties and according to a particular embodiment, the modulus of elasticity of the metal wire is between 180 and 220 GPa.

The electrical bushing 104 has at least two attachment holes 108 which are arranged on either side of the connector 102 when it is in place on the electrical bushing 104.

Stirrup 106 has two legs 110a-b. One of the ends of each leg 110a-b is provided with a hook 112 which is inserted into one of the attachment holes 108 to attach the bracket 106 to the electrical bushing 104.

The two other ends of the legs 110a-b are interconnected by a transverse bar 114 which comes by rotation (arrow 50) to rest on an upper surface 120 of the connector 102 to lock it onto the electrical bushing 104. The upper surface 120 is opposite the attachment holes 108.

The shows the assembly 100 in a free position in which the yoke 106, and more specifically the crossbar 114, is not yet against the upper surface 120 of the connector 102 and the latter is therefore free and can be separated from the bushing electrical 104.

The shows the assembly 100 in a locked position in which the yoke 106, and more specifically the crossbar 114, is against the upper surface 120 of the connector 102 and the latter is therefore no longer free and cannot be separated from the electrical crossing 104.

Each leg 110a-b comprises a winding 116a-b of the wire constituting it and extending over at least one turn. These windings 116a-b thus create a reserve of elasticity which facilitates the establishment of the crossbar 114 against the upper surface 120 of the connector 102. In addition, this reserve of elasticity makes it possible to compensate for the dimensional variations of the different parts of the assembly 100. In addition, the windings 116a-b facilitate the grip of the stirrup 106 during its installation or its removal.

In the embodiment of the invention shown in Figs. 1 to 3, each winding 116a-b is at the junction between a leg 110a-b and the crossbar 114. Each winding 116a-b is here in a plane containing the two legs 110a-b.

The shows variant embodiments, where the stirrup 406 has each winding 416a-b along a leg 410a-b, that is to say that a part of the leg 410a-b extends on both sides other side of winding 416a-b. Each winding 416a-b is here in a plane perpendicular to the plane containing the two legs 410a-b.

In the embodiment of the invention of Figs. 1 to 3, the connector 102 is an angled connector and the upper surface 120 here takes the form of a bridge fixed to the body of the connector 102.

The crossbar 114 has a V-shaped bend 122 whose tip 124 lodges in a recess 126 of the upper surface 120, here the bridge, in order to hold the stirrup 106 even better in the locked position.

As shown in , the crossbar 414 can take another shape and here it has a U-fold. In this embodiment, the additional locking can be achieved by a groove at the level of the upper surface 120 parallel to the bottom of the U or by any other means for enclosing the bottom of the U.

Of course, the shape of the crossbar 114, 414 is independent of the position of the windings 116a-b, 416a-b on the legs 110a-b, 410a-b.

In the embodiment of the invention shown in , connector 502 of assembly 500 is a straight connector and upper surface 520 has a cylindrical shoulder around connector 502 and crossbar 514 of yoke 506 takes the form of an arc of a circle which is positioned on a part of the cylindrical shoulder.

In the embodiment of the invention shown in , the windings 416a-b resume the positions presented in , but they could resume those of the .
