Definitions

  • the invention relates to a fully insulated connector with the features specified in the preamble of claim 1.
  • plugs have at least one plug pin, which is optionally attached in an insulated holding body.
  • a grip body made of insulating material is injection molded around the part of the plug pins on the connection side and, if appropriate, the holding body.
  • So-called European plugs with two parallel or slightly tapered plug pins are widely used, for example.
  • the connecting ends of the plug pins, which are surrounded by the handle body in the finished state, are sleeve-like and each have a receiving channel running in their longitudinal direction for inserting and crimping the strands of a stripped connecting line.
  • connection between a plug pin and a connecting line is shown in US Pat. No. 2,297,785.
  • the receiving channel for inserting and crimping the connecting line is divided in the insertion direction one after the other into an outer envelope area of larger cross-sectional width for receiving the insulated connecting line and an adjoining inner, narrowed contact area of smaller cross-sectional width for receiving only the stripped wire end of the connecting line.
  • the crimping takes place both in the envelope and in the contact area of the connector pin, which makes it particularly intimate and resistant to tension Connection between the connecting line and the connector pin is achieved.
  • connection lines which are stripped at their ends, are inserted into the receiving channels of the plug pin connection ends.
  • the connection ends are then squeezed together by means of a pressing device, as a result of which the connection lines are each crimped with the plug pins, that is to say fixed to them.
  • the handle body is overmolded.
  • the present invention seeks to provide a connector in which the Conventional connection between the connecting line and the plug pin is improved in terms of safety technology, so that the source of danger described is basically eliminated purely by design measures. A complex test and the investment of appropriate test equipment can be omitted.
  • At least the envelope region has a length which is the same size as or greater than the stripping length of the stranded end of the connecting line. If the end of the stranded wire is now inserted into the receiving channel with a projecting stranded wire, the wire is bent in the opposite direction to the insertion direction, but after the insertion movement has been completed, it lies within its entire length within the envelope area and cannot therefore protrude from the receiving channel. This basically eliminates the risk that a stranded wire can penetrate to the surface of the handle body.
  • connection end according to the invention can be used advantageously not only with plug pins but also with plug sockets or other electrical connection elements.
  • the connecting line By adapting the inner diameter of the contact area of the receiving channel to the wire diameter of the connecting line, particularly good contact is ensured in the contact area, since the wire bears almost all around on the inner wall contact surface of the receiving channel. Since at the same time the length of the contact area is equal to or greater than the stripping length of the strand end, the connecting line can run into the receiving channel with the full length of its stripped strand end be inserted. So that the connecting cable lies cleanly in the receiving channel, reliable contact, firm mounting and maximum security is ensured that no stranded wire passes through to the surface of the subsequently molded handle body.
  • an annular stop surface is formed for the edge edge of the insulation sleeve of the connecting line on the strand end.
  • the reaching of the insertion end position is indicated by a clear resistance, which is advantageous with regard to the mechanical production of the connector.
  • the machine part causing the insertion movement of the connecting line can be controlled via the mechanical resistance. Due to the funnel-like design of the diameter step, the strand can slide freely into the contact area of the receiving channel, whereby a disturbance of the strand structure itself is already avoided.
  • the known double crimping of the connecting line with the plug pin in its contact and envelope area also enables a particularly firm connection between the connecting line and the plug pin in the subject matter of the invention.
  • the elastic insulating material of the insulating sleeve nestles at the second crimping point in the envelope area formally against the squeezed inner wall of the receiving channel, thereby ensuring a particularly intimate connection between the connecting line and the receiving bore.
  • the achievable deduction value is thus significantly improved, which improves the longevity and reliability of the connector according to the invention.
  • the European plug is present as a plug bridge 1, as shown in FIG. 1.
  • the plug bridge 1 consists of a vertical U-shaped holding body 2 and the two metal plug pins 3.
  • the holding body 2 is made in one piece from a sprayable plastic material and holds the plug pins 3 in a form-fitting manner parallel to one another in its two U-legs 4.
  • the web-like U-base 5 defines the distance between the two connector pins 3.
  • the insertion ends 7 of the connector pins 3 located at the front in the insertion direction 6 project coaxially from the U-legs 4 of the holding body 2 and can be inserted into the insertion openings of a socket (not shown).
  • the sleeve-like connecting ends 8 of the plug pins 3 are each provided in their longitudinal direction with a receiving channel 9, into each of which the wire 10 of a stripped connecting line 11 is inserted.
  • a firm connection between the strand 10 and the plug pin 3 is ensured by crimping (not shown), which essentially corresponds to a squeezing of the sleeve-like connection end 8 with the strand 10.
  • FIG. 2 shows how the connecting line 11 is inserted into the receiving channel 9 in addition to the strand 10 with the edge region 12 of its insulation sleeve 13 on the connection side.
  • the periphery of the edge region 12 lies flat against the inner wall 14 of the receiving channel 9.
  • the receiving channel 9 is enlarged in depth. It extends into the part of the connector pins 3 surrounded by the holding body 2, 2 '. This makes it possible for a predetermined sleeve length 16 and stripping length 17 of the stranded end 24 of the connecting line 11 to insert the edge region 12 of the connecting line 11 into the receiving channel 9.
  • a preferred embodiment is not shown, in which only the sleeve length 16 is increased, which likewise enables the edge region 12 of the insulation sleeve 13 to be inserted.
  • the receiving channel 9 is divided into two areas in order to increase the insulation security and for optimum contact and anchoring of the connecting line 11 on the plug pin 3. These are the contact area 18 which is on the inside with respect to the insertion direction 6 and which corresponds to the diameter of the stranded wire diameter 22 and the outer, radially widened sleeve area 19 which corresponds to the diameter of the outer diameter 23 of the connecting line 11 with the insulation sleeve 13.
  • the lengths of the contact 18 and sleeve area 19 are each greater than the stripping length 17 of the strand end 24 of the connecting line.
  • a protruding stranded wire 15 (exaggerated in FIG. 2) is always bent backwards parallel to the longitudinal direction of the plug pin and is basically within the envelope region 19. You can not protrude radially in the direction of the surface of the handle body 21 shown in dashed lines, which is injected after crimping the connecting lines 11 with the connector pins 3 around the entire assembly for handle-side full insulation of the connector.
  • the diameter step 20 between the contact area 18 and the cladding area 19 is funnel-shaped.
  • the diameter step 20 is at the same time an end stop for the front edge of the insulation sleeve 13 and thus for the insertion movement of the connecting line 11 in the case of machine production.
