Definitions
- the present invention relates, in general, to a high voltage assembly comprising separable elements and more particularly to such a high voltage assembly in which the continuity of electrical insulation between the separable elements is ensured by means of an element in insulating, elastically deformable material.
- the electrical connection is conventionally carried out by means of paired electrical contacts maintained in rigid insulating blocks, themselves arranged in metal envelopes allowing a secure mechanical assembly of the connection elements, for example at additional threading and tapping means on enclosures or a bayonet device.
- This sealing problem is particularly important when the high-voltage assembly is in a rotating system, for example the sheaths of certain X-ray radiography devices. It is then necessary to provide complex sealing means such as bellows rings to prevent leakage of oil or grease at the interface between the separable elements, in particular under the effect of temperature when the assembly is used to compensate for the variation in volume.
- the object of the present invention is therefore to produce a high-voltage assembly comprising separable elements, in which it is not necessary to use oil or grease to ensure the continuity of electrical insulation between the separable elements from the whole.
- the invention also aims to provide a high voltage assembly comprising separable elements which can be easily assembled during manufacture or installation and disassembled after use or for intervention.
- a high voltage assembly comprising at least two separable elements, each of the separable elements comprising at least one electrical contact having a transverse end face, said contacts of a separable element being electrically connected to said contact of the other of the separable elements when the separable elements are combined, in which the continuity of the electrical insulation around the contacts is achieved by means an insulating element of electrically insulating and elastically deformable material, deformed by compression, when the separable elements are connected to each other.
- the deformable insulation element ensuring the continuity of the electrical insulation is an elastically deformable joint, made of insulating material, disposed between the end transverse faces of rigid blocks of insulating material so as to surround the (or) electrical contact (s).
- the seal is deformed by compression between the end transverse faces of the rigid blocks of insulating material, to achieve continuity of electrical insulation of the high-voltage assembly, when the separable elements are combined.
- the elastically deformable joint can be made of any flexible, elastically deformable insulating material, having suitable electrical insulation characteristics and a hardness suitable for being able to be compressed between the blocks of material insulating from separable elements and being sufficiently deformed to fill perfectly, at the compressed state, the space between the rigid insulating blocks around the contacts.
- the flexible insulating joint adapts perfectly to the end transverse faces of the rigid insulating blocks and thus remedies any surface imperfections of these end transverse faces.
- the flexible, elastically deformable seal is made of a suitable elastomeric material, such as a silicone elastomer.
- the Shore A hardness of the flexible insulating material of the joint is generally between 10 and 50, preferably between 10 and 30.
- the pressure exerted by the separable elements on the flexible insulating joint must be sufficient to achieve the desired electrical insulation. Obviously, this pressure will depend on the hardness (flexibility) and the nature of the gasket material and the high operating voltage of the assembly.
- the flexible insulating joint may be a removable joint, that is to say it constitutes a separate element from the separable elements.
- this joint can also be secured to a transverse end face of a rigid insulating block, for example, by fixing using an adhesive suitable for said face.
- the end transverse faces of the rigid blocks made of insulating material for separable elements have a convex shape where the flexible joint has a biconvex shape, so that when the separable elements of the assembly meet, it forms temporarily annular wedge-shaped spaces between the flexible joint and the end transverse faces of the rigid insulating blocks of the elements, allowing air to escape from the interface between the two separable elements, until these spaces have completely disappeared when the two separable elements have reached their final coupling position and the flexible joint compressed under the effect of the pressure exerted by the rigid blocks of insulating material occupies the entire space between the blocks of insulating material of the two separable elements.
- This produces a high-voltage assembly comprising separable elements which, when these are joined together, have excellent continuity of electrical insulation.
- the convexity of the terminal transverse faces of the insulating blocks or of the flexible removable joint must be such that the wedge-shaped spaces created during the joining of the separable elements are only a few degrees to allow the air to escape and thus avoid that air is trapped at the interfaces between the separable elements and the seal, and to ensure that the insulating flexible seal leaves no air gap remaining when the separable elements are in their final meeting position.
- the convexity is such that the angle of the wedge-shaped spaces is generally between 1 and 5 °.
- a high voltage connector which comprises two separable elements.
- a first of the separable elements consists of a hollow frustoconical envelope, open at one end, of rigid insulating material, provided in its bottom wall with one or more electrical contacts, for example female contacts.
- the second separable element comprises a frustoconical block of electrically insulating, solid material, elastically deformable by compression and the front face of which is intended to abut against the bottom wall of the frustoconical envelope and comprises one or more electrical contacts, for example male contacts, intended to be connected with the female contact (s) of the first separable element.
- the angle at the top of the rigid frustoconical envelope of the first separable element is slightly greater than the angle at the top of the frustoconical insulation block of the second separable element, so that, when the two separable elements are simply nested one inside the other, that is to say without compression being exerted on the deformable insulation block of the second separable element, there is a small angular annular space, for example from 1 to 5 °, between the inner side wall of the rigid frustoconical envelope and the outer side wall of the frustoconical block of elastically deformable insulating material.
- the height of the elastically deformable insulating block is slightly greater, for example from 1 to 5 mm, than the depth of the interior volume of the hollow rigid frustoconical envelope.
- the elastically deformable insulating block when the second separable element of the high-voltage connector is fitted into the first separable element, then compressed, for example by means of a tightening nut provided on the second separable element and cooperating with an additional thread provided on the support in which is adapted the first separable element, the elastically deformable insulating block, is deformed so that the elastically deformable material completely fills the interior volume of the hollow frustoconical envelope, coming into close contact and without discontinuity with the internal walls of this envelope .
- the air is expelled and evacuated as the compression deformation of the block of elastically deformable insulating material up to that the block of elastically deformable insulating material completely fills the interior volume of the frustoconical envelope when the tightening nut is screwed into its final position.
- This ensures continuous electrical insulation, without the risk of the presence of air included and without the need to use an insulating oil or grease.
- the elastically deformable insulating block regains its initial shape and dimension.
- the insulating block of the second separable element is preferably made of a suitable elastomer, such as a silicone elastomer.
- This material generally has a Shore A hardness of between 10 and 50, preferably between 10 and 30.
- the pressure exerted on the block of elastically deformable insulating material must be such that it allows a reduction in the height of the block to the value of the depth of the internal volume of the rigid frustoconical envelope. Obviously, this additional height of the insulating block of elastically deformable material must be such that the block, when it is completely deformed by compression, completely fills the interior volume of the hollow, rigid frustoconical envelope.
- the electrical contact (s) of the second separable element are generally arranged in recesses formed in the front face of the block of elastically deformable insulating material so that these contacts do not project outside this front face of the insulating block.
- these recesses are shaped and dimensioned to receive the complementary electrical contacts of the first separable element. This avoids any risk of deterioration of the electrical contacts of the second separable element when handling the conoector.
- the electrical contacts arranged in the recesses of the insulating block of material elastically deformable are male contacts, and more preferably male contacts laterally forming a contact spring intended to be introduced into complementary female contacts carried by the bottom wall of the hollow rigid frustoconical envelope of the first separable element.

- the angle thus obtained is generally a few degrees.
- the convexity of the terminal transverse faces 4a, 4b of the rigid blocks 3a, 3b must be such that annular wedge-shaped spaces are formed, but must not be so large that it would no longer be possible to make them disappear.
- These annular spaces by compression of the flexible seal 6 when the separable elements 1a, 1b meet.
- the value of the angle ⁇ will obviously also depend on the hardness of the insulating material of the joint 6. In general, this angle ⁇ will be between 1 and 5 °.
- annular space is thus formed in the form of a wedge widening towards the periphery of the rigid blocks 3a and 3b of the separable elements between the convex terminal transverse surfaces 4a and 4b of these blocks and the transverse surfaces of the joint removable in elastically deformable insulating material of annular shape, this space reducing to finally completely disappear under the effect of the compression of the removable annular seal 6 when the separable elements are brought together in their final position.
- the air is expelled from the interfaces between the convex transverse end faces 4a and 4b of the rigid insulation blocks of the separable elements and the seal 6 and is not trapped between the terminal transverse faces of the rigid blocks of the separable elements and the transverse faces of the removable seal, for example in the event of existing defects in the end transverse faces of the rigid insulating blocks of the separable elements.
