Definitions

  • the present invention relates to a press contact for low-current plugs for their solder-free wiring of electrical conductors, in which a cutting-like contact piece penetrates the insulation of a conductor under pressure and presses into the conductor wire in a contact-producing manner.
  • Press contacts for solder-free wiring have been shown to be relatively rational in production, in which a cutting-like contact piece cuts through the insulation of a conductor and presses slightly into it under pressure Penetrates conductor material making an electrical contact.
  • Such a press contact is known from document EP-A-0 145 315.
  • a disadvantage here has been shown to support the cutting-like contact piece and conductor directly on the plastic of the plug, which is not very suitable for absorbing the necessary pressing pressure, so that contact defects are the rule with such plugs.
  • highly conductive precious metals such as silver or gold are used, which has a further expensive effect.
  • the relatively sensitive counter-spring contacts interacting with the cutting-like contact pieces have to be arranged in the socket of the installation and can be damaged there when the installation is created.
  • a longitudinally slotted conductor guide sleeve is formed on a spring contact, through the slot of which a contact blade penetrates into a conductor inserted into the guide sleeve, the contact blade protruding from a slot edge of the guide sleeve via an articulated notch.
  • the contact blade on the conductor side and near the joint notch has a support cam intended for pressurizing the conductor lying in the guide sleeve.
  • the guide sleeve is assigned a conductor stop on the contact side.
  • the present invention relates to the use of a plurality of press contacts according to the invention in a low-current connector, each of which extends in an elongated chamber of the connector housing, the contact blades penetrating corresponding slots in the housing and protruding from the latter to such an extent that they are used for the wiring necessary pressing pressure can be generated.
  • a rational wire connection can be achieved in that the guide sleeves of the press contacts used in the chambers of the connector housing are assigned a distributor piece for automatically distributing the conductors of a multiple cable over the guide sleeves.
  • the press contact 1 as shown in FIGS. 1 to 3 consists for example of nickel silver or the like.Contact materials and comprises a so-called spring contact 8, the contact arms of which are preloaded against one another and which is suitable for receiving a mating connector pin, which is known per se and no further explanations are required here.
  • a longitudinally slotted conductor guide sleeve 13 for the pluggable reception of a conductor 5 is formed on the spring contact 8.
  • a contact cutting edge can pass through the slot 14 of the sleeve 13 9 penetrate the conductor 5 with suitable knife tips 11.
  • This contact cutting edge 9 is in this case formed on a joint notch 12 projecting upward from a slot edge 15 of the guide sleeve 13 in the illustration. By generating a pressing pressure on the contact cutting edge 9, it can be brought from the open contact position shown in FIG. 1 to the contact producing position shown in FIG. 2.
  • the contact cutting edge 9 pivots about a support cam 10, which is located on the conductor side near the joint notch 12 on the contact cutting edge 9 and finds its abutment on the conductor 5.
  • This support cam 10 also forms an effective strain relief, such that a cable pull cannot affect the contact point between the conductor and the contact blade.
  • the guide sleeve 13 is assigned a conductor stop 16 on the contact side, which is supported on the press contact body via a web 17, as is particularly shown in FIG. 3 in more detail.
  • Fig. 4 now shows a low-current connector with a plurality, here four in a row next to each other, according to the invention Press contacts 1.
  • Such a low-current connector according to FIG. 4 is only mentioned, for example, and can be constructed in a very varied manner with more or less such press contacts in a single-row arrangement or with several contact levels. The principle according to the invention remains unaffected.
  • the press contacts 1 each extend in an elongated chamber 20 of the plug housing 2, the contact blades 9 then penetrating respective slots 21 in the housing 2 and thus protruding from the latter to such an extent that the necessary for the wiring Press pressure can be generated.
  • the housing surface can be a stop for the press handle (not shown) and can form a measure of the depth of penetration of the knife tips 11 into the conductor wire 6 of the conductor 5 through the insulation 7.
  • the guide sleeves 13 of the press contacts 1 used in the chambers 20 of the connector housing 2 can be assigned a distributor piece 3, which automatically distributes the exposed conductor ends 5 of a multiple cable 4 to the associated guide sleeves 13.
  • a low-current plug thus results from the above for multiple contacts, which can be manufactured very efficiently and which has an absolutely safe and permanent contact between the conductor and the spring contact.
