Definitions

  • the invention relates to a connector, in particular hermaphrodite connector, with a housing and elongated contacts inserted therein, which have a connection end and a plug end facing the plug face of the housing, the housing engaging over the connection end of the contacts and providing at least one strain relief clamp for connection cables (see FR-A-2337951).
  • Such connectors are known in practice as charging connectors. They are used to transmit high current between the charging station and the battery of battery-operated vehicles, and between the battery and engine of such a vehicle.
  • connectors which consist of two housing halves screwed together, the contacts being inserted into one housing half for assembly of the connectors, after which the other housing half is then placed over it and screwed to the first housing half.
  • connector housings are also known, in which the contacts can be inserted in the direction of their longitudinal extent, locking pins or clips inserted into the housing transversely to the plugging direction then having to be used in order to lock the contacts in the plugging direction. This is not always easy because the contacts can twist around their longitudinal axis and are only held in position by the locking pins.
  • these housings also consist of two together screwed housing halves.
  • the assembly of the connectors described above takes place in two stages.
  • the first stage the pre-assembly, at least the housing halves have to be screwed together, but it is also useful in the known connectors to use the contacts and the fastening elements so that the fastening elements, which are relatively small, are not lost when the connectors are shipped.
  • the second assembly stage which the customer, d. H. at the vehicle manufacturer, the connectors must then be partially taken apart again, after which the contacts are connected to the ends of the connecting cables and inserted back into the housing.
  • work has to be carried out twice, which increases the cost of using such connectors. If you want to avoid this duplication of work, the customer receives a large number of components, some of which are small, which he does not know exactly how to assemble. This also causes delays that make the use of such connectors more expensive.
  • At least one stop shoulder is formed on the contacts between their plug end and their connection end that the housing is divided transversely to the direction of insertion and a frame with the plug-in face, in which the contacts are inserted with their plug-in end from the side facing away from the plug-in face until the abutment shoulder rests against the frame, and two cover halves articulated and closable on the side of the frame facing away from the plug-in face via a cover hinge each has, which cover the connection ends of the contacts in the closed state, and that the lid hinges each have at least one pull tab and one pressure tab which are attached to the side of the cover facing the frame, the pull tab being held on the side of the frame facing away from the mating face , while the pressure tab on the side of the contact shoulder facing away from the frame engages behind.
  • the housing can then be constructed in three parts, whereby the two cover halves can be identical, so that only two injection molding tools are required if the housing is produced by injection molding, as usual.
  • the free end of the pressure tabs is adapted to the peripheral shape of the contacts and rests on the contacts in the closed state of the cover halves. This has the advantage that the pressure straps press the housing halves with the pull straps into the locking recesses in the frame, so that the hinges are braced.
  • the pressure tabs point obliquely to the contacts in the direction of insertion and are designed to be elastically bendable, so that the contacts between the cover halves and the frame are fixed in position, and the hinges are elastically tensioned.
  • the webs laterally frame the lid halves, since then lateral forces that, for. B. can occur when a connector falls down, do not attack directly on the cover halves.
  • catches of the webs are designed as catch recesses, while the counter catches are designed as catch wedges which engage in the catch recesses, it can always be seen from the outside whether the cover halves are correctly engaged or not.
  • the strain relief clamp for the connecting cables consists of two halves, one half being articulated on the rear of a cover half facing away from the frame via an elastically bendable tabs.
  • the two cover halves are also held in the closed state of the connector by the strain relief clamp, the halves of which are usually held together by screws.
  • the latching connection between the cover halves and the lateral webs is therefore essentially only an assembly aid, which is no longer absolutely necessary when the connector is in use.
  • the bendable tab is designed as a strip of the cover surface which is laterally delimited by slots and which extends from approximately the middle of the cover surface to the rear of a cover half. This relatively long tab enables the halves of the strain relief clamp to adapt to both relatively thick and relatively thin cables.
  • each half of a strain relief clamp can have at least four holes for fastening screws each, which are connected to the four holes in the other half of the clamp are aligned, with two diagonally opposite holes each having a smaller diameter than the other two holes.
  • the strain relief clamps can be connected in this way with self-tapping screws, the threaded parts of which cut into the holes of smaller diameter. Since a total of four holes are provided, each half of the clamp has two large holes that are aligned with two small holes on the other half of the clamp. In this way, the fastening screws can always be screwed into the strain relief clamp from one side, which in turn simplifies assembly.
  • the lateral webs of the frame extend as far as between the halves of the strain relief clamp and each have two bores which are aligned with the bores of the clamp halves.
  • the covers are additionally fastened to the side webs of the frame, so that the hinge for the cover halves is also relieved.
  • Hermaphrodite contacts having circular disk segments are formed if triangular cover surfaces are formed on the free-ending edge of the mating face of the frame, which cover the end faces of the mating ends of the hermaphrodite contacts inserted in the connector, and if on the base surface of the mating face from which the mating ends of the contacts emerge until to the free-ended edge of the mating face elevations are formed, which are arranged in front of the open flanks of the mating contacts as contact protection, it is impossible to reach fingers with live parts in the mating face of the connector when the connectors are not plugged together.
  • a connector 1 which has a housing 2 and elongated hermaphrodite contacts 3 inserted therein.
  • this connector is shown with a view of the mating face 4. It can also be seen there that the hermaphrodite contacts in cross section have the shape of two opposing circular segments, the plug end 5 facing the plug face 4 being covered by triangular cover surfaces 6. In addition to the free flanks 7 of the plug ends 5, up to the end edge of the mating face 4, elevations 8 in the form of pins or the like are provided, which, together with the cover surfaces 6, ensure protection against contact and make it impossible to touch the contacts 3.
  • the housing 2 of a connector consists of a frame 9, into which the hermaphrodite contacts 3 are inserted from the side opposite the plug face 4, and of two cover halves 10 and 11, which form the connection ends 12 of the hermaphrodite contacts 3 cover and on the back of which the corresponding halves 14 and 15 of a strain relief clamp 13 are attached.
  • the lid halves 10 and 11 are hinged to the frame 9.
  • the hinges comprise a pull tab 16, the free end of which is provided with a locking wedge 17 which engages behind an opening 18 in the frame 9 from the inside, as can be seen particularly well from the upper half in FIG. 4.
  • the hinges comprise a pressure tab 18 which engages behind an abutment shoulder 20 of the hermaphrodite contacts 3, with which the hermaphrodite contacts 3 are also supported with respect to the frame 9. This can be seen particularly well from FIG. 2.
  • the hermaphrodite contacts 3 are axially caught with their contact shoulder 20 between a contact surface of the frame 9 and between the ends of the pressure tabs 19 when the cover halves 10 and 11 are in the closed state shown in FIG. 2.
  • the pressure tabs 19 point obliquely forward from the cover halves 10 and 11 in the direction of insertion of the hermaphrodite contacts 3 and are designed to be flexible.
  • the free ends of the pressure tabs are adapted to the outer contour of the hermaphrodite contacts and lie on the outer contour of the hermaphrodite contacts 3.
  • two lateral webs 21 which extend to the rear are formed on the rear side of the frame 9 facing away from the plug face 4.
  • the webs have a vertical section in about the first two thirds and a horizontal section 23 in the last third.
  • latching openings 24 are provided which cooperate with corresponding latching wedges 25 arranged laterally on the outer sides of the lid halves when the lid halves are closed (see FIG. 5).
  • the clamp halves 14 and 15 of the strain relief clamp 13 are arranged on the back of the cover halves 10 and 11, respectively.
  • the clamp halves are fastened to the cover half 10 or 11 via a tab 26 which lies in the cover surface of a cover half and extends to approximately the middle of the cover half.
  • the tab 26 is formed in that the cover is slotted into the side of the tab 26 up to approximately the center of the cover.
  • the clamp halves 14 and 15 are relatively rigid in themselves and have bores 27 and 28 at their ends.
  • the holes 27 and 28 lie side by side so that they form the corners of a square.
  • the bores 27 have a larger diameter than the bores 28, two bores of the same diameter each lying diagonally opposite one another.
  • the clamp halves 14 and 15 are fastened by so-called self-tapping screws, which can be inserted through the bores 27 of larger diameter and cut their threads into the edge of the bores 28 of smaller diameter.
  • bores 29 are provided which are aligned with the bores 27 and 28 of the cover halves when the cover halves 10 and 11 are attached to the frame 9.
  • a frame 9 (see FIG. 6) and two cover halves 10 and 11 (see FIG. 7), as well as two hermaphrodite contacts 3 and two self-tapping screws are required.
  • the two cover halves 10 and 11 if necessary at all, are hung with their pull tabs 16 in the openings 18 of the associated frame 9.
  • the connector thus prepared then arrives at the customer.
  • the customer connects the two hermaphrodite contacts 3 with the ends of the associated connecting cables, which z. B. can happen by squeezing the terminal ends 12.
  • the hermaphrodite contacts 3 are then inserted with half-opened cover halves (see FIG. 4 below) in push-through openings in the frame, the elastic pressure tabs 19 being able to deflect up and down until the hermaphrodite contacts with their contact shoulders 20 after passing the pressure tabs 19 on the frame 9 concerns.
  • the hermaphrodite contact must pass a narrow point in the through-opening adapted to the shape of the profile cross section, as a result of which the hermaphrodite contact is automatically aligned in its correct position.
  • the pressure tabs 19 then engage behind the contact shoulders 20.
  • the cover halves can then simply be pressed together, the lateral locking wedges 25 engaging in the locking openings 24 on the lateral webs of the frame 9, so that the two cover halves 10 and 11 snap shut.
  • the cover surfaces 6 and the elevations 8 do not interfere when plugged together, but they offer effective protection against accidental contact with the contacts.
