Definitions

  • the invention relates to a connection device, which is provided in particular for electrical equipment.
  • Electrical equipment may be ballasts for gas discharge lamps, in particular so-called series reactors, small transformers or the like. Occasionally, such, referred to as electrical equipment, devices must be preceded by devices that serve to protect the devices, to meet general safety conditions, for filtering or other purposes. In addition, such resources must be connected to an external network, including a connection device anyway is required.
  • an electrical connection terminal which serves as an electrical equipment connection means.
  • the terminal has a terminal housing with a temperature-sensitive element housed therein. This is attached to the underside of the terminal housing so that it is the first to be affected by a heating of a carrier sheet on which it is mounted.
  • the terminal housing contains three individual, juxtaposed terminal elements, two of which are connected to the electrical component. Each terminal element has two clamping screws each, two of which serve to fix connection wires of the component.
  • the thermally sensitive electrical component is located in a separate chamber and thus assumes its temperature.
  • the response speed in particular to rapid changes in temperature, depends on the quality of the heat transfer between the heat-transferring wall of the housing and the component.
  • connection device with increased reliability create.
  • connection device according to claim 1 This object is achieved with the connection device according to claim 1.
  • connection device has a housing in which the connection terminals and additionally at least one electrical component are accommodated.
  • the electrical component is connected via spring contacts with the terminals, wherein the spring contacts are not accessible from the outside. They are thus protected against external manipulation - by connecting and disconnecting individual wires from the terminals, the electrical contact between the spring contacts and the terminals can not be affected.
  • connection device also allows a particularly simple production. All you have to do is populate the housing with the terminals and the electrical component. This is a pure joining process in which the spring contacts make contact with the corresponding terminals. Special other measures are not to be taken.
  • a terminal is formed as a feed-through terminal, while the other two terminals are each connected to a terminal (spring contact) of the device, but not with each other.
  • These last two terminals are preferably arranged on a line, which is aligned parallel to the longitudinal axis of the other, having two terminal points, terminal.
  • the terminals are preferably designed as screw terminals. If necessary, however, they can also be designed as spring clips, as insulation displacement contacts or otherwise. Also mixed contact systems are possible in which both spring terminals and screw terminals are available.
  • the electrical component may be a PTC resistor which serves as a temperature-sensitive current limiting component.
  • the component can also be designed as a varistor, which derives overvoltages between the two mutually parallel terminals, which are then designed as pass-through terminals.
  • it can be designed as an interference suppression capacitor or as an otherwise electrical component.
  • it is a temperature-sensitive device, which is arranged between the terminals and the bottom-side wall of the housing in order to detect as quickly as possible the temperature of the carrier on which the connection device is mounted.
  • the component is pressed against the lower housing wall.
  • This can be done by a spring means integrated into the housing or by another spring means done.
  • the spring contacts also serve as spring means for pressing the component to the heat-transferring wall of the housing.
  • the component is preferably secured by latching means in the housing. It can then be inserted into a corresponding compartment of the same after insertion of the terminals in the housing, wherein the spring contacts, the necessary electrical connections automatically.
  • the two chambers are connected for the affected terminals with the receiving chamber for the electrical component.
  • the two receiving chambers for the terminals of the receiving chamber for the component separating wall may have a corresponding slot, which is penetrated by the spring contacts.
  • FIG. 1 is a ballast 1 for a fluorescent lamp illustrated.
  • the series reactor 1 is representative of various electrical equipment that can be electrically connected via a connection device 2 according to the invention.
  • the series reactor 1 comprises a carrier plate 3, which carries an iron core 4 with a winding 5 and the connection device 2.
  • connection device 2 has an existing example of plastic and thus electrically insulating housing 6, which is bolted to the support plate 3.
  • the housing 6 encloses receiving spaces 7, 8, 9, 11, in which, like the FIGS. 2 and 3 illustrate, terminals 12, 13, 14 and an electrical component 15 are arranged.
  • the terminals 12, 13, 14 are held by their clamping screws in their respective receiving spaces 7, 8, 9. In addition, they can sit frictionally in the housing 2.
  • the terminal 14 forms a feed-through terminal whose one clamping screw is used to connect a supply line and the other clamping screw for contacting a terminal of the winding 5. To connect the other terminal of the winding 5, the terminal 13 is used, while the terminal 12 is used to connect an outer line.
  • connection device 2 goes out FIG. 4 and FIG. 5 out.
  • the housing 6 has two juxtaposed, approximately cuboidal sections 16, 17, which are interconnected by two, a mounting hole 18 bounding webs 19, 21 are. From the top of the sections 16, 17 extend tubular extensions 22, 23, 24, 25 away, which, as usual with Luster terminals, are arranged in two parallel rows and accommodate clamping screws.
  • FIG. 4 illustrates the clamping screws 26, 27 of the terminals 12, 13.
  • the accommodating receiving chambers 7, 8 are separated from each other by a partition wall 28 and electrically insulated. In addition, they are from the receiving space 9 ( FIG. 5 ) electrically isolated.
  • the receiving space 11 is disposed below the receiving spaces 7, 8 and separated therefrom by a bottom 29. This one takes off as if FIG. 8 shows, not the entire base of the receiving spaces 7, 8, but leaves, quite the opposite, a slot 31 through which the receiving spaces 7, 8 are connected to the receiving space 11.
  • the electrical component 15 is preferably approximately cuboid and is located with its flat bottom 32 against a thin lower housing wall 33, which closes the housing 6 downwards.
  • the housing wall 33 is in the assembled state of the connection device 2 areally on the support plate 3.
  • the lateral forces 34, 35, 36, 37 act with regard to the support of the forces exerted by a clamping screw which passes through the fastening bore 18.
  • FIG. 5 and 6 which terminate the receiving space 11 laterally, or extend below the receiving space 9 away from its bottom on the support plate 3.
  • the receiving space 11 is a flat, cuboid-shaped space, which is open below the receiving space 7 to an end face, like the FIGS. 4 and 5 illustrate. Towards the opposite side of the receiving space 11 is also open, as FIG. 6 illustrated, wherein lateral projections 38, 39 narrow the opening. If necessary, the case can be completely closed here as well FIG. 4 shows.
  • a locking means 41 which is formed by one or more, formed on the housing wall 33 locking lugs 42, 43, such as FIG. 4 combined with FIG. 7 illustrated.
  • the locking lugs 42, 43 each have an oblique ramp shape toward the outside, while they drop steeply towards the inside. As a result of the inherent elasticity of the housing wall 33, they can yield resiliently when the component 15 is pushed into the receiving space 11.
  • the device 11 is for example a thermal switch or a combined current-sensitive thermal switch. This can for example be designed in the form of a PTC element, which is preheated by current flow and high impedance when reaching a transition temperature.
  • the device 15 connects the two terminals 12, 13 electrically.
  • it has at least two spring contacts 44, 45 which are obliquely upwardly away from the upper side 46 or the end faces 47, 48 of the component 15.
  • the spring contacts 44, 45 are slightly curved, with the top 46 include an acute angle. They can be directed towards each other or even directed.
  • the spring contacts 44, 45 are preferably protected against corrosion, for example by a silver coating.
  • the base material may be spring steel.
  • the terminals 12, 13 are also preferably protected against corrosion with the same material (eg silver).
  • the on their preferably planar underside abutting spring contacts 44, 45 thus provide a secure electrical contact.
  • they load the device 15 in the direction of the housing wall 33 and thus form a spring means, which contributes to the planar contact of the underside 32 on the housing wall 33.
  • connection device 2 is mounted as follows:
  • connection terminals 12, 13, 14 are first inserted into their receiving spaces 7, 8, 9 or, if they have a certain excess, pressed.
  • the receiving space 9 may be provided with ribs 51, which narrow it and cause a press fit of the respective terminal 14.
  • Such projections, ribs or the like may also be provided in the other receiving spaces 7, 8.
  • the component 15 is now inserted into the receiving space 11. For this it is only in the longitudinal direction (in FIG. 4 from right to left), wherein its spring contact 44 through the slot 31, according to FIG. 8 , running. Thus, both spring contacts each reach its associated terminal 12 and 13.
  • the spring contacts 44, 45 may be arranged at diagonally opposite points of the device 15, so that the device 15 in two possible positions in the receiving space 11 can be used. This is the bottom 29, like FIG. 8 illustrated, preferably shortened so that it leaves the receiving space 8 downwards, ie towards the receiving space 11 substantially free. If, on the other hand, a directional confusion of the component 15 is to be avoided, the bottom 29 can be lengthened accordingly, whereby a correspondingly polarized component can then only be introduced into the accommodating space 11 in one insertion direction.
  • connection device can be produced efficiently and automatically. This applies in particular with regard to the screwless connection technology between the component 15 and the connection terminals 12, 13. This results in a compact design of the connection device 2. In addition, a total of only two-pole design results in contrast to previously known three-pole versions, the assembly confusion not excluded ,
  • an electrical component 15 accommodated therein is connected via screwless contacts, for example spring contacts 44, 45, to two connection terminals 12, 13 which are otherwise electrically separate from one another.
  • screwless contacts for example spring contacts 44, 45
  • connection terminals 12, 13 which are otherwise electrically separate from one another.
  • the spring contacts 44, 45 can simultaneously effect an improvement of the heat transfer to the component 15, if this is designed as a temperature sensor. This is achieved by the spring contacts 44, 45 pressing the component 15 against an underside housing wall 33 of the housing 6.
