  • the invention relates to a base for a relay, a support body for guide elements of such a base and a method to manufacture a base for a relay with the features the preamble of the independent claims.
  • Relays are electrical components that depend on one Input current one or more output circuits closed or be opened.
  • the input and the output circuit are galvanically isolated from each other.
  • Relay used in base, which in turn with electrical Lines of an input or an output circuit connected are.
  • the relays usually have contact pins that with Contacts in the base can be brought into electrical contact.
  • Known bases are typically approximately cuboid and have connection points for electrical on two sides Lines on. The connection between the contacts for the Contact pins and the connection points are made via electrical Connections individually inserted into the housing of the base are.
  • connection points connecting cables often on two opposite sides of the base must be connected and therefore partly in the cross from one side of the base must be led to the other side of the base.

  • the upper housing part 14 is provided with openings 19 through which contact pins of the relay are feasible and with below of the openings 19 arranged contacts 3 (see Figure 2) in Can be brought in contact.
  • the housing 2 is on one side 5 of the Provide contacts 3 with steps 7.
  • connection points 4 for connecting the base 1 to electrical Lines provided.
  • the upper housing part 14 has openings 15 to insert the cables into the connection points 4.
  • the Housing upper part 14 also has openings 18 through which Screws 16 (see Figure 2) for attaching the cables to the Connection points 4 designed as cable clamps can be actuated can.
  • the contacts 3 below the openings 19 and the connection points 4 are by guide elements 6 (see Figures 3 to 4 and Figure 6) connected to each other.
  • connection points 4 on the same side 5 of the contacts 3 are arranged, all electrical contact connections on the side 5 of the base 1. Connections on both sides or routing cables over the central area 8 of the base, in which the relay is to be used is not required there.
  • connection points 4 Due to the arrangement of the connection points 4 in stages 7 several rows of connection points can be provided one above the other his.
  • the width B can thereby according to the embodiment in Figure 1, where three rows of three connection points 4 are reduced by a factor of one to three.
  • connection points 24 are attached, which are connected to contacts 23 are connected.
  • the connection points 24 are used for connection the excitation circuit of a relay, i.e. e.g. the coil.
  • the 2 shows the base 1 from FIG. 1 with the upper housing part removed 14 shown.
  • a Carrying body 10 used in the lower part 13 of the housing 2 .
  • the support body 10 carries the electrical Guide elements 6 (see Figure 3), which on the support body arranged contacts 3 with the likewise on the supporting body 10 connect the arranged connection points 4.
  • the connection points 4 are with the guide elements 6 integrated in the support body 10 by means of protruding from the support body 10 further guide elements 17 connected.
  • On the guide elements 17 are as cable clamps trained connection points 4 arranged.
  • the in the Connection points 4 used cables are with a screw or a drawbar 16 clamped.
  • the support body 10 is with the contacts 3 and the connection points 4 prefabricated and then in the lower part 13 of the housing used. This enables a particularly simple one and quick assembly.
