Definitions

  • This invention relates to an electrically conducting junction component for connecting a conductor of a printed circuit board (hereinafter: PCB) to an electrical lead of a separate electrical unit.
  • the junction component according to the invention may be used with advantage particularly in light sources, e.g. in discharge lamps including compact fluorescent lamps integral with an electronic ballast.
  • the electrical unit in this case is represented by the discharge tube.
  • the electric conductors coming from the electrodes have to be connected with the terminals of the ballast, i.e. of the PCB.
  • the terminals of the ballast i.e. of the PCB.
  • one electrode is placed at each end of a discharge tube and the electric arc works between these electrodes.
  • the electrical inleads of the electrodes have to be connected with the electronic unit, i.e. with the corresponding terminals of the PCB.
  • the task of the ballast is to start and to maintain the electric arc in the discharge tube.
  • the electronic components necessary for operating the discharge tube or at least most of them are placed on the PCB in a way known in itself.
  • the objective of the invention was to provide a junction component for connecting a PCB and a separate electrical unit, which, when making the connection between these, does not expose the place of electrical connection on the PCB to mechanical load.
  • the invention is based on the recognition that the sensitive part of the junction component can be relieved of mechanical load by such a junction component which has a slot for accepting the electrical lead of the electrical unit and which is provided with component parts, e.g. tabs bent out from its own plate material, supported by the rim of the PCB so that the load appearing during inserting the lead into the slot acts on the said tabs.
  • component parts e.g. tabs bent out from its own plate material
  • the objective set was, according to the invention, achieved by means of a junction component for connecting the electrical leads of a PCB and a separate electrical unit, which electrically conducting junction component is fixed on the PCB and has a slot suitable for accepting the leads protruding from the electrical unit.
  • This junction component is composed of a base part and a connection part, of which the base part is embedded in the PCB and is connected with the corresponding output of the printed circuit, and the electrical leads of the electrical unit are connected to the connection part of the junction component with the orientation of the electrical leads being, where the connection is made, substantially perpendicular to the plane of the PCB.
  • This junction component is characterized in that the direction in which the electrical lead is connected to the connection part is substantially parallel to the plane of the PCB, the base part is composed of a base plate and tab(s) bent out from it, which tab(s) protrudes (protrude) into hole(s) formed in the PCB, and is (are) embedded into it in a way providing electrical contact also with the PCB, the base plate joins the tab(s) with the connection part, and the connection part is formed so that its plane is substantially the same as or parallel to the plane of the base plate.
  • the connection part is placed at or adjacent to the edge of the PCB and the tab(s) passes (pass) through the PCB and is (are) fixed to it by means of soldering.
  • slots increasing the resilience of the connection part are formed in the base plate, adjacent to the connection part.
  • the junction component has also a clamping arm that protrudes from the plane of its base plate.
  • the invention also relates to a junction component for connecting a PCB and a separate electrical unit which electrically conducting junction component is fixed on the PCB and has a slot suitable for accepting the lead protruding from the electrical unit.
  • This junction component consists of a base part and a connection part, of which the base part is embedded in the PCB and is connected with the corresponding output of the printed circuit, and the electrical leads of the electrical unit are connected to the connection part with the orientation of the electrical leads being, where the connection is made, substantially perpendicular to the plane of the PCB.
  • connection part is represented by a clamping fork having resilient prongs, and protruding from the base plate of the base part and the prongs of the clamping fork are placed in substantially parallel direction to the PCB, and a slot is provided between them for accepting an electrical lead, the direction of which is substantially perpendicular to the PCB.
  • the clamping fork protrudes beyond the PCB at its edge and a cutout is provided in the PCB around the slot of the clamping fork.
  • the end portion of the slot for introducing the electric lead is formed as an outwardly broadening space bordered by slant guiding surfaces.
  • the inner end of the slot can preferably continue in a broadening hole.
  • notches narrowing the prongs of the clamping fork and increasing resilience are made on the outer side of the prongs of the clamping fork, adjacent to the base plate.
  • the junction component shown in Figs. 1 and 2 which may be made by means of slitting and cutting operations, has a base part 11 and a connection part 12.
  • the material of the junction component is a metal plate.
  • the base part 11 is in connection with PCB 13 shown partly in Figs. 1 and 2, and the connection part 12 is in connection with an electrical lead 10 being a part of an electrical unit, e.g. a discharge tube (not shown).
  • the end portion of the electrical lead 10 intended to make electrical connection is shown as dashed lines in Figs. 1 and 2.
  • connection part 12 has a clamping fork 2 which protrudes from and is in the plane of the rectangular base plate 1 of base part 11 and is also perpendicular to the longer side of the rectangle.
  • a slot 4 is placed between the prongs 3a, 3b of the said clamping fork 2 (Fig. 1).
  • the width e of slot 4 is preferably smaller than the diameter d of the lead 10, and the slot 4 broadens in the region of its outside end.
  • the space 14 having increasing width outwards is bordered by the inner slant guiding surfaces 15 of the prongs 3a, 3b (Fig. 1).
  • the inner end of the slot 4 leads into hole 5.
  • Semicircular-shaped notches 6 are placed on the outer side of the prongs 3a, 3b, adjacent to the base plate 1. Starting from these notches 6, slits 7 are placed which increase the resilience of the connection part 12 and protrude into the base plate 1 and are perpendicular to its longitudinal direction. These slits 7 together with the said hole 5 make it easier for the prongs 3a, 3b of the clamping fork 2 to move apart from each other to a small extent, i.e. to be deformed resiliently, when the lead 10 is pushed into the slot 4 during connecting. Notches 6 play a role primarily in the assembling and manufacturing process.
  • Tabs 8a, 8b and 8c of the same height m (Fig. 2) starting and bent out in the same direction from and perpendicular to the plane of the base plate 1 of the base part 11 belong to the base part 11.
  • the tabs 8a and 8b are placed at the opposite sides of the clamping fork 2 at the outer sides of said slits 7.
  • the tab 8c is placed in line with the clamping fork 2 but on that side of the base plate 1 which is opposite to the clamping fork 2.
  • the junction component is symmetrical to the geometrical center plane X which is perpendicular to the base plate 1 and passes through the slot 4 and is denoted by a dash-dot line.
  • the height m depends on the thickness of the sheet material of the junction component, and it should also fit to the sheet thickness f of the PCB 13 (Fig. 2). This is necessary because the junction component is fixed to the PCB 13 by the tabs 8a, 8b and 8c of the base part 11. Each of the tabs 8a, 8b, 8c being parallel to each other is passed through a through opening 17 formed in the PCB 13, and the ends of the tabs slightly protruding from the PCB 13 are fixed to the PCB 13 by solder 13a. In case of the example according to Figs. 1 and 2, the junction component is countersunk into the PCB 13 in the way that the connection part 12 does not protrude in lateral direction from the PCB 13.
  • the embodiment of the junction component seen in Fig. 3 corresponds to that according to Figs. 1 and 2, therefore the reference numbers of these latter ones are used to denote the identical construction parts.
  • the solution seen in Fig. 3 differs from that illustrated in Figs. 1 and 2 in that the junction component is not countersunk into the PCB 13, but the clamping fork 2 of the connection part 12 protrudes outwards from the edge of the PCB 13.
  • the base plate 1 of the base part 11 and the clamping fork 2 of the connection part 12 are parallel to the plane of the PCB 13 in this case as well.
  • connection of the base part 11 to the PCB 13 is made in the way that only the tab 8c is passed through and fixed to the PCB 13 (the opening for this and the solder on the other side of the PCB 13 are not shown in Fig. 3 for better overview), while the tabs 8a and 8b fit to the edge of the PCB 13.
  • the mechanical loads occurring when the lead 10 is inserted into the slot 4 of the clamping fork 2 are taken up by the tabs 8a-8c in this case as well.
  • the embodiment of the junction component seen in Fig. 4 differs from those according to Figs. 1 through 3 as follows: it has only two tabs 8a, 8b perpendicular to the base plate 1 of the base part 11, which tabs 8a, 8b protrude from this base plate 1 in one direction and are placed at a spacing h one below or above the other. Also, an arm 9 protrudes in the direction opposite to the tabs 8a, 8b, which arm 9 is provided for the purposes of the manufacturing process: controlled by the manufacturing program, the junction component is gripped, moved and embedded into the PCB 13 by an automatic equipment (not shown). In Fig. 4, the PCB is not shown and construction components described previously are denoted by the reference numbers already used. Connection of the junction component according to Fig.
  • junction component relieves the sensitive and delicate electrical contact points on the PCB of the mechanical loads occurring during the assembly of the PCB with a separate electrical unit, e.g. in manufacturing light sources, such as compact fluorescent lamps, integral with an electronic ballast. This results in the lengthening of lifetime of the product.
  • junction component according to the invention the operation of making the electrical contact will be significantly simplified: soldering the leads of the electrical unit or a more complicated contact making is not needed.
  • the operation for making a mechanical (snap-in) joint will automatically ensure that the electrical connection is performed. Assembling can be well automated.
  • the junction component is small-sized, thus requires small room and can be used for operating units of practically any shape, position, number and size.
  • the same junction component can be used for PCBs of different shape, number and position.
  • the electrical connection is of excellent safety (the force needed to maintain the contact is provided by resilient deformation and the direction of electric lead is perpendicular to the printed-circuit board), in addition the possibility to collide with certain mounts will be reduced.
