Definitions

  • the invention relates to an electrical connector with at least two connector pins, which are fastened in a bridge made of mechanically strong insulating material and to whose connecting ends projecting through the bridge are connected with stranded conductors of a connecting line, in which on the side of the connecting ends of the connector pins a cap made of insulating material is attached, the cross section of which corresponds to the cross section of the breaks and which surrounds the connection ends of the plug pins, leaving an opening for the connecting line from the outside, and in which the bridge, the cap and the end of the connecting line are made of an insulating material, are surrounded by injection molded connector body (GB-A-2 095 924).
  • the invention further relates to a method for producing such a connector.
  • Such plugs are available in two or more poles in a wide variety of forms on the market today. They should be able to be mass-produced as simply as possible, but at the same time it must be ensured that the electrical connection between the plug pins and the stranded conductors of the connecting line is flawless. These connection points are particularly problematic because they have to be and remain flawless not only in electrical but also in mechanical terms.
  • the connector according to the document GB-A-2 095 924 mentioned at the outset is designed as an angled connector which is molded onto a connecting line with stranded conductors.
  • a cap made of insulating material is arranged which has a recess on the side through which the connecting line connected to the plug can pass when the cap is placed in a mounted position on a bridge of the plug holding the plug pins.
  • GB-A-1 595 783 discloses a plug which has a housing-like cover which can be moved on the connecting line for a part of the contact points of the plug.
  • the invention has for its object to provide a connector with associated manufacturing process in which it is ensured in a simple manner and with no significant additional outlay of material that even in automatic production individual wires from stranded conductors connected to the connector pins do not protrude sideways and that the connection points between stranded conductors and Plug pins are strain relieved.
  • the attachment of the cap which surrounds both the connecting ends of the plug pins and the ends of the stranded conductors fixed to the same from the outside, ensures that individual wires of the stranded conductors cannot protrude sideways. This applies regardless of how the stranded conductors are connected to the connector pins. Individual wires of the stranded wire, which are not detected, for example when crimping or welding, and therefore initially protrude sideways, are gripped by the cap before the plug body is sprayed and bent back in the direction of the connecting ends of the plug pins. This ensures in a simple manner that there are no individual wires on the surface of the same in the finished connector body.
  • the cap is particularly easy to assemble as a prefabricated component.
  • FIG. 1 An embodiment of the subject of the invention is shown in the drawings.
  • the embodiment shows a two-pin connector.
  • the invention can also be used for plugs with more than two plug pins.
  • the shorter word "line” is used for the sake of simplicity.
  • connection ends 4 and 5 of the connector pins 2 and 3 protrude through the bridge 1.
  • they are designed as sleeves.
  • the ends of two stripped stranded conductors 6 and 7 are inserted into the connection ends 4 and 5, as can be seen in FIG. 2.
  • Terminal ends 4, 5 and stranded conductors 6, 7 are connected to one another, for example, by squeezing.
  • the two stranded conductors 6 and 7 are the electrical conductors of two wires 8 and 9 of a line 10, at the end of which a plug is to be attached.
  • the plug body 11 to be produced by injection molding is indicated by dashed lines in FIG. 1.
  • a cap 13 made of insulating material is attached, which is shown in FIGS. 4 and 5 in its assembled position.
  • the cap 13 includes the connection ends 4 and 5 from the outside. It is closed on the side facing away from the bridge 1 except for an opening 14 for the passage for the line 10.
  • the cap 13 can preferably rest against the bridge 1 in its end position. It can also lie close to the line 10 in the area of the opening 14.
  • the procedure for producing the plug according to FIG. 5 is as follows: A cap 13 is first pushed onto the end of a line 10. Then the jacket of line 10 is removed to expose wires 8 and 9. The wires are then stripped so that their stranded conductors 6 and 7 are exposed. Then the stranded conductors 6 and 7 are electrically conductively connected to the connection ends 4 and 5 of the plug pins. This is achieved, for example, by squeezing the connection ends 4 and 5 with the stranded conductors 6 and 7 located therein. In order to ensure that no individual wires 12 protrude outwards in the finished plug after the cap 13 has been applied, it is necessary that the axial length of the connection ends 4 and 5 corresponds at least to the exposed length of the stranded conductors 6 and 7.
  • the cap 13 is pushed onto the structure prepared in this way by sliding on the line 10 until it abuts the bridge 1.
  • the cap 13 encompasses the connection ends 4 and 5 from the outside and bends any protruding individual wires 12 in the direction of the connection ends 4 and 5. If the connection ends 4 and 5 have the minimum length specified above, then no individual wire can protrude outwards.
  • the line end thus completed is placed in an injection mold, in which the plug body 11 is injected.
  • the cap 13 has a cross-sectional shape which corresponds to the cross-section of the bridge 1. It is meant to mean that the cap 13 does not protrude substantially sideways beyond the profile of the bridge 1, however the bridge 1 looks.
  • the cap 13 is preferably made in one piece. However, it can also consist, for example, of two half-shells which are assembled before the cap 13 is installed. When the cap 13 is pushed onto the connection ends 4 and 5, it is necessary for the cap 13 to be displaced as a one-piece component.
  • the cap 13 can rest against the bridge 1 in its end position. In this end position, it can also be fixed by latching elements on bridge 1.
  • the cap 13 has two opposing, hook-shaped webs 16 which, in the end position of the cap 13, grip around the bridge 1 and thus bring about a locking of the two parts.
  • the webs 16 form axial extensions of the cap 13. They can be provided with a bevel on the inside for easier pushing on. In principle, more than two webs 16 can also be attached to the cap 13.
  • the cap 13 also has an inward-pointing spout 15. In this way, in the assembled position, it simultaneously relieves the strain on the connection points between the connection ends 4 and 5 of the connector pins 2 and 3 and the stranded conductors 6 and 7 are used.
  • the wires 8 and 9 are appropriately preformed before the cap 13 is slid on, specifically in the direction of the bridge 1.
  • the grommet 15 presses on the wires 8 and 9 and takes the same as far as is apparent from Fig. 5.
  • the cores are then bent approximately in an S-shape and the connection points are effectively protected against tensile loads which can occur by pulling on the line 10.
  • a two-wire line 10 is shown with a jacket surrounding the two wires 8 and 9.
  • the connector can also be connected to cables with more than two wires. It is also possible to use a so-called flat cable, in which two or more wires without a jacket lie side by side. With this type of line, the stripping process is not necessary.
