Description

Title of the invention: BRACKET FOR FIXING A CONNECTOR TO AN ELECTRICAL CROSSING Technical field

[0001] The present invention relates to a bracket for fixing a connector to an electrical feedthrough, as well as an assembly comprising a connector, an electrical feedthrough and such a bracket. STATE OF THE PRIOR ART

[0002] The fixing of a connector on an electrical crossing is often carried out using a stirrup which has two legs. At one end of each leg is made a hook which is fixed in a hooking hole provided on the electrical crossing.

[0003] The other two ends of the legs are connected by a crossbar which is compressed above the connector in order to lock it onto the electrical feedthrough.

[0004] Although such a stirrup is generally satisfactory, the legs can sometimes be too rigid, which makes locking the crossbar even more difficult.

[0005] It is therefore necessary to find a solution which increases the elasticity of the caliper whilst maintaining a sufficient level of clamping force. Statement of the invention

[0006] An object of the present invention is to provide a bracket for fixing a connector to an electrical feedthrough which has a large mounting range.

[0007] For this purpose, a bracket is proposed for fixing a connector having an upper surface on an electrical feedthrough comprising attachment holes, said bracket being made of a wire and comprising:

[0008] - two legs, where one end of each leg is provided with a hook intended to be inserted into a hanging hole, and

[0009] - a crossbar connecting the other two ends of the legs, where said crossbar is intended to rest on the upper surface,

[0010] where each leg comprises a winding of the wire constituting it and extending over at least minus one turn.

[0011] With such an arrangement, the two windings constitute reserves of elasticity which facilitate the locking of the stirrup on the connector.

[0012] According to a particular embodiment, each winding is at the junction between a leg and the crossbar.

[0013] According to a particular embodiment, each winding is along a leg.

[0014] According to a particular embodiment, the crossbar has a V-shaped fold whose tip is designed to fit into a recess in the upper surface.

[0015] According to a particular embodiment, the crossbar has a U-shaped fold whose bottom is designed to be gripped by any suitable means provided at the level of the upper surface.

[0016] 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.

[0017] The invention also proposes an assembly comprising a connector having an upper surface, an electrical feedthrough comprising attachment holes and a bracket according to one of the preceding variants. Brief description of the drawings

[0024] DETAILED DESCRIPTION OF EMBODIMENTS

[0025] Figs. 1 to 3 show an assembly 100 according to an embodiment of the invention which comprises a connector 102 which is here an angled connector, an electrical feedthrough 104 to which the connector 102 is connected, and a bracket 106.

[0026] The stirrup 106 is made 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.

[0027] The electrical feedthrough 104 comprises at least two attachment orifices 108 which are arranged on either side of the connector 102 when it is in place on the electrical feedthrough 104.

[0028] The stirrup 106 comprises two legs 110a-b. One end of each leg HOa-b is provided with a hook 112 which is inserted into one of the hooking holes 108 to fix the stirrup 106 to the electrical feedthrough 104.

[0029] The two other ends of the legs 110a-b are connected to each other by a transverse bar 114 which comes to bear by rotation (arrow 50) on an upper surface 120 of the connector 102 to lock it on the electrical feedthrough 104. The upper surface 120 is opposite the hooking orifices 108.

[0030] [Fig. 2] shows the assembly 100 in a free position in which the stirrup 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 electrical feedthrough 104.

[0031] [Fig. 3] shows the assembly 100 in a locked position in which the stirrup 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 feedthrough 104.

[0032] 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 positioning of the transverse bar 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 gripping of the stirrup 106 when it is being positioned or removed.

[0033] 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.

[0034] [Fig. 4] shows alternative 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 either side of the winding 416a-b. Each winding 416a-b is here in a plane perpendicular to the plane containing the two legs 410a-b.

[0035] 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.

[0036] The transverse bar 114 has a V-shaped fold 122 whose tip 124 fits into a recess 126 of the upper surface 120, here the bridge, in order to keep the stirrup 106 even better in the locked position.

[0037] As shown in [fig.4], the transverse bar 414 can take another shape and here it has a U-shaped 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 making it possible to grip the bottom of the U.

[0038] Of course, the shape of the crossbar 114, 414 is independent of the position of the windings 116a-b, 416a-b on the legs HOa-b, 410a-b.

[0039] In the embodiment of the invention shown in [fig.5], the connector 502 of the assembly 500 is a straight connector and the upper surface 520 has a cylindrical shoulder around the connector 502 and the crossbar 514 of the stirrup 506 takes the form of an arc of a circle which is positioned on a portion of the cylindrical shoulder.

[0040] In the embodiment of the invention shown in [fig.5], the windings 416a-b take up the positions shown in [fig.4], but they could take up those of [fig.l].
