Definitions

  • the invention relates to a contact spring bushing according to the preamble of patent claim 1.
  • a plug-in contact spring punched out of flat material is known from DE-OS 36 36 711.
  • This plug contact spring consists of a connecting part for electrical jumper wires and a plug part for receiving a pin-like mating connector.
  • the plug part is designed such that the bending arms, each carrying a contact spring, are bent over the high edge when plugged in.
  • the connecting part in this plug-in contact spring is designed such that the electrical jumper wires must be pretreated for contacting, at least the insulation having to be removed. It is not specified in detail how the jumper wires are attached to the connector.
  • a method for producing a clamping device for connecting electrical lines by cutting the insulation is known from DE-AS 15 90 699. These are specially shaped insulation displacement clamps which are stamped in such a way that a slot is formed into which a wire to be contacted is clamped. This creates a high pressure so that a perfect electrical connection is guaranteed.
  • the insulation displacement connection is described, which has the advantage that the insulation of wires does not have to be removed beforehand. None is said about the way in which a plug connection can be implemented.
  • An electrical contact device with a rigid auxiliary spring is known from US Pat. No. 4,583,812. It is a contact socket, the spring pressure of which is reinforced by an additional auxiliary spring.
  • This auxiliary spring is a separate part, which is shown individually in Figure 1. It is pushed onto the contacting springs and is designed so that it adapts to the shape of the body of the contact device. This requires an additional, relatively complicated assembly process, in which auxiliary springs and contact springs are mechanically connected and fixed to one another, so that a good and durable connection is created between the two parts. For this, special notches are provided on the body of the contact device and retaining tongues on the auxiliary spring.
  • the object of the invention is to present a contact spring book which can be produced from one part and does not require any pretreatment of the connecting wires to be contacted.
  • the contact spring bushing should be such that it can be produced without assembly work and can be inserted into an associated insulating housing, with no additional fastening parts being required. No additional tools should be required for contacting connecting wires.
  • the actual contact springs 4 are spoon-shaped and are enclosed by compression springs 3, which increases the contact pressure.
  • These compression springs 3 are connected by strips 10 to the socket body 1, as is clearly shown in FIG. 2. As part of the bending processes necessary for the manufacture of the contact spring bushing, these strips 10 are pressed together in a meandering shape 11, so that the compression springs 3 come to rest on the contact springs 4. In a subsequent bending process, the compression springs 3 are pressed against the contact springs 4 pressed.
  • the shaft 5 of the socket body 1 has insulation displacement clamps 6 which are bent vertically out of the plane by a bending process.
  • the connecting wire to be contacted is inserted into these insulation displacement terminals without removing the insulation. However, this only happens when the contact spring bushing has been inserted into the insulating housing 8.
  • hooks 7 are provided, which are bent obliquely out of the plane and are used for strain relief of the connecting wire.
  • FIG. 5 A perspective sectional drawing of a housing 8 for receiving the socket body 1 is shown in FIG. 5.
  • the socket body 1 is inserted from below into the housing 8, with barbs 17 located on the socket body 1 being hooked into notches 18.
  • the shaft 5 of the socket body 1 is then located in the upper part of the housing 8.
  • detents 12 are attached, which are intended for the contacting tool 9.
  • This contacting tool 9 is produced together with the housing 8 in one operation and in one piece. It is connected to the housing 8 by webs 14 designed as predetermined breaking points.
  • the contacting tool 9 has slots 16 which are arranged such that they are located above the insulation displacement contacts 6.
  • housings are predominantly made in one piece, as shown in FIG. 6.
  • cable cores can be introduced in pairs in one operation into a housing 8 of this type, which is equipped with socket bodies and consists of two chambers.
  • the manufacturing processes for producing the contact spring bushing can be carried out both for the socket body 1 and for the housing 8 by automatically controlled machines. Automatically operating machines are also provided for inserting the socket body 1 into the housing 8 and for contacting the connecting wires.
