Definitions

  • the present invention relates to electrical connectors and their assembly process.
  • the cylindrical electrical connectors generally comprise an envelope in which is housed a stack of parts having aligned passages for receiving contact pins.
  • the stack may have a retaining element and be sealed in the envelope with a resin before the insertion of the contact pins in their passages.
  • the disadvantage of this assembly process is that the resin can penetrate into the passages provided for the pins and partially seal them making it difficult or impossible to insert the pins.
  • such a connector comprises a casing in which is housed a stack of parts having aligned passages intended to receive contact pins, the stack comprising at least one washer forming a pin retaining element and an insert separated from the 'envelope by a space.
  • the stack is held in the envelope by a deformable laminated material which surrounds the interlayer and the washer and which fills the space between them and the envelope.
  • the laminated material is a porous tape to be wrapped around a sleeve. Two more sleeves are required to assemble and to prevent the ribbon from crumpling. The device allowing the assembly therefore comprises three sleeves and the process is ultimately quite long to implement.
  • the invention proposes an electrical connector in which the retention element is sufficiently rigid so that the assembly requires only a single sleeve. This result can be obtained thanks to a particular design of the parts to be assembled.
  • the subject of the invention is therefore an electrical connector comprising a casing and an insulating body allowing the housing of at least one electrical contact, the insulating body being in abutment on an interior shoulder of the casing, the interior of the casing and the insulating body being of generally cylindrical shapes, the fixing of the insulating body in the envelope being ensured by the deformation, in the space separating them, of a retention element. It is characterized in that the interior of the envelope and the insulating body also have chamfered surfaces, the retention element coming, after deformation, to fill at least the space between said chamfered surfaces to oppose the separation of the insulating body and the envelope.
  • the retention element can be in the form of a band or in the form of a ring.
  • the retention element can be associated with a material such as resin making it possible to increase the tightness of the connector.
  • a material such as resin making it possible to increase the tightness of the connector.
  • the retention element being provided with lateral slots, making it possible moreover to remove the play between the parts to be assembled, these slots can be filled with resin.
  • This resin can be introduced in one form or another before the positioning of the retention element.
  • the retention element will preferably be metallic. Aluminum lends itself particularly well to the function devolved to the retention element.
  • Step a) can be preceded by a preliminary step consisting in introducing a preform of a material such as resin.
  • FIG. 1 represents a retention element used by the assembly method according to the patent cited above.
  • This element consists of a strip 1 of laminated material.
  • the laminate consists of a porous ribbon such as a phosphor bronze lattice, a woven or nonwoven glass fiber ribbon.
  • This tape can be serrated as shown in Figure 1 and is impregnated with a thermosetting material such as an unpolymerized epoxy resin.
  • Figures 2 and 3 relate to the method of assembling an electrical connector according to the cited prior art.
  • the assembly is carried out as follows. We start by winding the ribbon 1 around a stack constituting an insulating body and comprising an insert 2, a retaining washer 3, a ring 4 and a seal 5.
  • the insert 2 is sealed with the washer 3.
  • the seal 5 and ring 4 can be glued to this set.
  • the insulating body is pierced, in the axis of the seals 14, with aligned passages to receive contact pins.
  • the laminate 1 is deformed using appropriate tools.
  • This tool comprises three coaxial sleeves: an inner sleeve 6, an intermediate sleeve 7 and an outer sleeve 8.
  • the insulating body is first placed in the inner sleeve 6, the end of the sleeve coming into abutment on the shoulder 9 of the washer 3. With the outer sleeve 8 raised, as shown in solid lines in FIG. 2, the laminate 1 is wound around the inner sleeve 6 so that an edge of the strip is located near the shoulder 10 of the insert 2. The outer sleeve 8 is then pushed to cover the tape 1 and take the position shown in dotted lines in FIG. 2. The cylindrical envelope 11 is then threaded onto the insulating body by pushing the outer sleeve 8 until the inner shoulder 12 of the envelope comes into abutment with the shoulder 13 of the interlayer 2. The outer sleeve 8 prevents the ribbon 1 from twisting or wrinkling during installation of the envelope.
  • the intermediate sleeve 7 is pushed forward in the space between the envelope 11 and the inner sleeve 6.
  • the ribbon 1 is deformed by filling all the possible space as shown in Figure 3.
  • the inner sleeve 6 is raised over a short distance, as shown in Figure 3, then we continue pushing the intermediate sleeve 7 to creep the laminate 1 around the shoulder 9 of the washer 3. In this way, the laminate maintains the stack in the envelope because of the filling of the groove 14 of the envelope 11 After polymerization of the resin by baking, the connector is then ready to receive its contacts.
  • the invention overcomes these drawbacks by the use of a more rigid retention element and a single sleeve, this being made possible by a particular design of the different parts of the connector.
  • FIG. 4 represents an electrical connector according to the invention during the assembly of its different parts.
  • the insulating body designated by the general reference 20 and the casing 21.
  • the casing has an internal shoulder 22 for receiving the insulating body as for the connector described above.
  • An essential characteristic of the envelope and of the insulating body is the presence of chamfered surfaces, respectively 23 for the envelope and 24 for the insulating body. These surfaces are shown in Figure 4, parallel to each other and located on the same level. This is not an obligation and other arrangements are possible as will be seen below.
  • the retention element 25 is made of a sufficiently rigid material so as not to require any particular precaution for its installation. In particular, left to itself it does not wrinkle when placed in the space between the envelope and the insulating body.
  • the retention element can be metallic, for example aluminum or copper. It can be in the form of a band which is wound up to introduce it into the space in question, or in the form of a ring or a split ring. The latter form facilitates its introduction.
  • the preform 26 can be in the form of a split washer 26 as shown in Figure 5.
  • the slot 28 is advantageously made at an angle so that, when it is crushed, there is actually a resin seal all over the periphery concerned.
  • the retention element 25 introduced between the insulating body 20 and the casing 21 remains blocked approximately at the place where it has been shown in FIG. 4 due to the chamfered surface 24.
  • a pusher in the form of a hollow cylinder exerting pressure in the direction indicated by the arrow, the element 25 will be put in place.
  • FIG. 6 shows the deformation taken by the element 25 during its positioning when it reaches the height of the chamfered surfaces 23 and 24.
  • FIG. 7 shows the retention element 25 in place, the pusher being removed.
  • the preform 26 has also been deformed and provides sealing to the connector.
  • the retention of the insulating body is effectively ensured by the surfaces 23 and 24 which prevent any movement of the element 25 and therefore of the insulating body 20.
  • the surface 24 also makes it possible to firmly hold the body 20 on the shoulder during pressing.
  • chamfered surfaces are of course possible without departing from the scope of the invention. These surfaces can be parallel to each other or not. They can even be tilted in opposite directions. The important thing is that they oppose efforts tending to separate the insulating body from the envelope.
  • FIG. 8 shows an example of a retention element 25 before it is mounted.
  • This element is in the form of a metal strip, for example aluminum.
  • slits 30 were made perpendicular to one of its edges. These slots facilitate the deformation of the retention element under the effect of pressure. It is then advantageous to arrange the slots according to a determined pitch, adapted to the diameters of the parts to be assembled. This will remove the play between the parts to be joined and will contribute to the centering of the insulating body 20 in the casing 21 as shown in figure 9. It is also possible to fill the resin slots for the use already mentioned.
  • the resin preform of FIGS. 5 to 7 can be integrated into the retention element, either as in the case of FIG. 8, or by coating or gluing. Thus there will be a minimum of parts to be assembled by a limited tool.
  • the retaining element may have a profiled section ensuring the function of blocking wedge for the insulating body and to eliminate the play existing between the parts to be joined.
  • the retention element (band or ring) can be placed on a press using a tubular plunger, the stroke of which is adjusted in advance.
  • the invention lends itself particularly well to the automation of the assembly process.
  • the retention element can also be made of plastic or any other deformable material with equivalent mechanical characteristics.
