Definitions

  • the present invention relates to electrical connectors comprising several contact elements (pins or sockets) intended to be coupled to a complementary connector.
  • the invention relates more particularly to electrical connectors of the type comprising a front insulator having passages for receiving parallel contact elements and provided with a shoulder limiting the advancement (or recoil) of the contact, a plate intended for s press against the insulation and provided with means such as tabs or fingers intended to lock the contacts in place by pressing said tabs against a shoulder formed on the contacts and turned towards the rear (or the front), and a pass wires, the plate resting against the front insulation.
  • the existing connectors of the type defined above are provided to allow individual disassembly of the contacts.
  • This disassembly requires the insertion of a tubular tool either from the front or from the rear of the connector, to spread the locking tabs of the shoulder provided on the contact.
  • This solution which may be of interest in connectors with a large number of signal transmission contacts, has serious drawbacks in many other cases. For example, in connectors that can be repaired by unqualified personnel without equipment, used in large numbers in the automotive industry or similar activities, it is desirable that the contacts can be removed without the need for having of a specific tool.
  • the invention proposes in particular a connector of the type defined above comprising a sleeve movable relative to the front insulator between a position for blocking the grommet and the plate for which the fingers are in abutment against the shoulder and a withdrawal position for which the fingers release the contacts.
  • this result is achieved by providing the front insulator, the plate and / or the locking ring with means which retain them one on the other when the locking ring is brought into the position where it releases the fingers.
  • Such a solution is particularly advantageous in the case of connectors intended to be mounted where a component escaping from the connector risks being housed in a part where it will be difficult to recover and where it can cause breakdowns.
  • the cooperating connectors shown in FIGS. 1 to 4 can be used in particular in automobile construction. They constitute one a plug 10 and the other a receptacle 10a each having two male contact elements or pins 12 and two female contact elements or sockets 14.
  • the components of the plug and the receptacle are identical, if this is only one of the connectors only (the plug in the illustrated case) comprises a ring 16 for locking two connectors one on the other which will be discussed below. Consequently, only sheet 10 will be described in detail.
  • This sheet includes a front insulator 18 pierced by four parallel passages for receiving contacts 12 and 14.
  • Each passage has a first shoulder 20 directed towards the rear, intended to serve as a stop for a corresponding shoulder provided on the contact and therefore to be fixed the position of the latter.
  • a recess formed in the front insulator 18, delimited by a shoulder 22, is provided to receive a contact retention plate 24.
  • This plate has locking fingers directed towards the front 25. In the embodiment of FIGS. 1 to 4, they have, when they are free, the shape shown in FIG. 2 and delimit a passage large enough for a bulge contact limited by the second shoulder can pass through it.
  • the plate 24 has external hooking hooks 26 whose role will appear later. These hooks pass through a grommet 28.
  • This plate has a central part 30 which is inserted into a central hole in the front insulation 18.
  • In the front flange 31 of the grommet are passages for the hooks 26.
  • the peripheral part and the central part of the grommet 28 have radial abutment surfaces intended to seal the rear part (and thereby to avoid losses by tracking).
  • the front insulator has tapered passages which push the locking fingers 25 inward during locking. In this position the locking fingers are in a position such that they cannot flex and therefore retain the contact shoulder for sure.
  • the locking fingers can be formed by splitting cylindrical extensions of the wafer 24, as in the case described in the French patent application mentioned above.
  • the connector according to the invention there can be no fault in retaining the contacts as a result of a loss of elasticity of the locking fingers, since they are kept bent by the conical passages.
  • Means are provided for keeping the plate 24 attached to the front insulator. They comprise, in the embodiment shown in Figures 3 and 4, a retaining notch 40 formed on the front insulator and preventing the insulator 18 and the plate 24 from moving axially apart from each other beyond the stop position of the notch against an elastic finger 50 formed on the plate 24.
  • the mechanical assembly intended to retain the front insulation 18, the plate 24 and the grommet 28 in the arrangement shown in FIG. 1, comprises a sleeve 32 having a rear narrowing of support against the grommet son 28 and an external bearing shoulder of a locking ring 36 having a thread intended to be screwed onto a corresponding thread 38 of the front insulator.
  • This ring has two axial grooves in which snap two diametrically opposite pins 37 of the front insulation 18.
  • Additional means are provided to prevent the sleeve 32 from completely separating from the ring 36 and from the plate 24. They include: - On the one hand, the windows made in the sleeve 32 and intended to receive the hooks 26 which then prevent the sleeve from moving back beyond the position shown in FIG. 2; - On the other hand two or four notches 33 formed at the rear of the sleeve 32, visible on the base 10a (shown in Figure 1 cut along a plane at 45 ° to the cutting plane of the plug 10).
  • the grommet 28 generally made of flexible elastomer, has not been inserted between the hooks 26, the latter can bend. It is therefore possible to pass the front edge of the windows of the sleeve 32 over. Once this engagement made and the grommet in place, the different parts remain attached to each other and only the contacts can be removed from the rear.
  • the locking ring 16 may, for reasons of simplicity, be constituted by a simple molded part made of flexible elastomer having a rear internal groove trapping a circular rib 42 of the front insulation of the plug 10. An internal front groove of this ring is cleaned so as to snap onto the rib 42 of the insulation before the base , by simple push.
  • the flexible blocking ring fulfills a triple function of locking, sealing and retention.
  • its rear part may include a step in which the front of the sleeve 36 engages when the latter is screwed in fully (FIG. 1).
  • the release of the contacts 12 and 14 during disassembly is conditioned by the maintenance of the elasticity of the fingers 25. This condition is no longer necessary in the variant embodiment shown in FIG. 5.
  • the fingers 46 for locking the contact elements 12 and 14 have at rest a shape such that they define a lower passage in the cross section of the bulging of the contact elements and they must move apart to allow insertion or extraction thereof. This spacing is prohibited, when the plug (or the base) is assembled, by the wall of a cylindrical recess 48 provided in the front insulator.
  • the fingers have a terminal thickening so as to slide on the barrel of the contact elements and to undergo no deformation and no permanent bending stress.
  • the thickenings have an internal chamfer facilitating the insertion and extraction of the contact elements. They are bent only temporarily, during the insertion or extraction of the contact elements, so that no permanent deformation by fatigue can hinder disassembly.
