Definitions

  • the invention relates to a multi-pole terminal according to the preamble of claim 1.
  • the connector is usually used to connect printed circuit boards.
  • the connecting terminal with a base surface of the housing is placed on the printed circuit board and solder pins which are led out of the base surface are inserted into the printed circuit board and soldered to the latter.
  • each row of the clamping poles has its own housing.
  • the housings of both rows are identical. The terminal poles are inserted into the housing from the front in the direction of insertion of the conductor wires.
  • the housing of the second row of the clamping poles sits on a spacer block, which is arranged in the insertion direction behind the housing of the first row and supports the housing of the second row. Bores are provided in the spacer block, into which the solder pins of the clamping poles of the second row are inserted, so that the spacer block holds and positions these solder pins.
  • the additional spacer block makes the known connection terminal expensive in terms of material.
  • the use of two separate housings for the two rows of terminal poles and the use of the additional spacer block also make the assembly of the known terminal complex.
  • the invention is based on the problem of creating a multi-pole connecting terminal with two rows of clamping poles arranged in a step-like manner, which requires little material and enables simple assembly.
  • connection terminal only a single, one-piece housing is provided. No additional measure is therefore necessary to avoid the the terminal poles of the to hold and position the second row receiving housing part.
  • the terminal rows of the first row are inserted into the housing from the front in the direction of insertion of the conductor wires.
  • the terminal row of the second row is inserted into the housing from the rear in the opposite direction. It is therefore not necessary to separate the two housing parts, which accommodate the first and the second row of clamping poles, for inserting the clamping poles.
  • clamp receptacles are provided on the housing, which fix the solder pins when the terminal poles are inserted.
  • the clamping receptacles formed in one piece on the housing make additional measures for holding and positioning the soldering pins superfluous.
  • the connecting terminal according to the invention thus requires a single, one-piece housing, into which both rows of the terminal poles are inserted, the solder pins of the terminal poles of the upper second row also being inevitably fixed.
  • the terminal therefore requires little plastic material for the housing and assembly is considerably simplified.
  • a particularly cost-effective design results if the housing has a recess behind the first row and under the second row of the terminal poles, into which only spring tongues project as clamping receptacles for the soldering pins of the terminal poles of the second row.
  • the spring tongues are expediently arranged in the base surface of the housing.
  • the spring tongues are therefore at a maximum distance from the housing part which receives the upper row of the clamping poles, which results in a particularly stable fixation of the solder pins.
  • the soldering pins are positioned directly in the base surface, so that there is a precise alignment with the contact holes in the circuit board.
  • the connecting terminal shown in the exemplary embodiment has a first row of nine clamping poles arranged next to one another and a second row of eight clamping poles arranged next to one another.
  • the second row of terminal poles is offset from the first row like a staircase arranged.
  • the connection terminal is used for the electrical connection of a circuit board, for which purpose the connection terminal is placed on the circuit board.
  • the solder pins of the clamping poles are inserted into holes in the circuit board and soldered to the conductor tracks.
  • the connecting terminal has a housing 10 made of plastic, which consists in one piece of two housing parts 10a for the first row of terminal poles and 10b for the second row of terminal poles.
  • the two housing parts 10a and 10b are arranged in a step-like manner, so that the second housing part 10b is offset backwards and upwards relative to the first housing part 10a.
  • the first housing part 10a has nine receiving chambers 12 arranged in a row next to one another, which are designed as blind holes that are open towards the front. From the top of the housing part 10a each lead holes 14 into the receiving chambers 12. In the lower bottom surface of the receiving chambers 12, an axially extending slot 16 is provided to the front, so that the receiving chambers 12 along this slot 16 against the lower base surface 18 of the Housing 10 are open.
  • clamping poles are used in each case for connecting conductor wires.
  • the clamping poles consist of a metallic clamping body 20 with an insertion opening 22, a wire protection 24 and a clamping screw 26 which is screwed into a threaded bore of the clamping body 20.
  • a solder pin 28 is formed on the underside of the clamping body 20.
  • the clamping body 20 of the clamping poles is inserted into the receiving chambers 12 from the front, the soldering pin 28 being inserted the slot 16 passes through and protrudes from the base surface 18 of the housing 10.
  • the clamping screw 26 is inserted into the respective bore 14 and screwed into the clamping body 20.
  • the housing 10 In the second housing part 10b, eight receiving chambers 30 are formed side by side in a row.
  • the receiving chambers 30 penetrate the housing 10 completely in the insertion direction from the front to the rear. From the top of the second housing part 10b, bores 32 lead vertically downward into the receiving chambers 30.
  • Behind the first housing part 10a and below the second housing part 10b, the housing 10 has a recess 34.
  • In the lower bottom surface of the receiving chambers 30 there are slots 36 which are open towards the rear of the housing 10.
  • the slots 36 represent an open connection between the receiving chamber 30 and the recess 34.
  • Clamping receptacles are provided on the vertical rear surface of the first housing part 10a, each consisting of a pair of spring tongues 38 integrally molded onto the housing part 10a.
  • the spring tongues 38 protrude perpendicularly from the rear wall of the first housing part 10a into the recess 34 and lie flush in the lower base surface 18 of the housing 10.
  • Each pair of spring tongues 38 includes between them a receiving slot 40 which, in the vertical projection, matches the Slit 36 coincides in a receiving chamber 30.
  • the receiving slots 40 are open towards the rear of the housing 10 and widen in a funnel shape at their open end. In the vertical projection below the inner end of the slots 36, the receiving slots 40 each have an enlarged one Snap-in receptacle 42.
  • Clamping poles are inserted into the receiving chambers 30 of the second housing part 10b, which coincide with the clamping poles of the first row, but have a longer soldering pin 44.
  • the clamping bodies 20 of the clamping poles of the second row are inserted into the receiving chambers 30 from the rear of the second housing part 10b, the soldering pins 44 reaching through the slots 36 and projecting into the cutout 34.
  • the free lower ends of the soldering pins 44 enter the receiving slots 40 of the spring tongues 38.
  • the clamping bodies 20 are completely inserted into their end position in which the soldering pins 44 rest against the inner end of the slots 36, then the lower ends of the soldering pins 44 into the respective latching receptacle 42 of the receiving slot 40 of the spring tongues 38.
  • the diameter of the soldering pins 44 is somewhat larger than the width of the receiving slots 40, so that the soldering pins 44 spread the spring tongues 38 slightly elastically apart when inserted into the receiving slots 40 until the solder pins 44 get into the extended locking receptacles 42.
  • the width of the latching receptacles 42 corresponds to the diameter of the soldering pins 44, so that the soldering pins 44 are held in position in the latching receptacles and the spring tongues 38 spring back into their tension-free position.
  • the solder pins 44 are so long that they protrude beyond the base surface 18 of the housing 10 formed by the spring tongues 38 by the same length as the solder pins 28 of the clamping poles of the first row.
  • clamping screws 26 are inserted from above through the bores 32, which pass through the wire protection 24 and are screwed into the threaded bore of the clamping body 20.
  • Conductor wires can be inserted from the front into the insertion openings 22 of the clamping bodies 20 of the clamping poles of the first and the second row and clamped by means of the clamping screws 26 and the wire protection 24.
  • the connection terminal is placed with the base surface 18 on a printed circuit board, the solder pins 28 and 44 being guided through bores in the printed circuit board and being soldered to conductor tracks on the printed circuit board.
  • the eight clamping poles of the second row are each offset by half a grid spacing from the nine clamping poles of the first row, so that the solder pins 28 and 44 protrude from the base surface 18 in a zigzag arrangement. This achieves a larger mutual distance between the soldering pins 28 and 44 and thus a larger leakage current path.
