Definitions

  • the present invention concerns a connecting device for connecting at least one external electrical conductor to an electrical connecting system of a photovoltaic solar module, with a connector housing for arranging on the solar module, and contacts arranged in the connector housing for connection to the electrical conductor and to the electrical connecting system of the solar module.
  • the invention also concerns a solar module with such a connecting device, and a method of producing such a connecting device.
  • a photovoltaic solar module typically includes a panel-like layer arrangement with solar cells, which generate electrical energy by a photovoltaic effect, arranged between the layers.
  • a layer arrangement of such a solar module includes a planar, radiation-side layer, for example in the form of a glass cover with a low degree of absorption, and a planar second layer, which is arranged on the back of the solar module and, for example, implemented on the form of a back glass cover.
  • the solar cells are arranged between these layers in an appropriate intermediate space, and are connected to each other within the layer arrangement by an electrical connecting system.
  • Solar module embodiments in which the electrical connecting system of the solar cells is connected outwards, for example to a load, on the back of the solar module, facing away from the radiation side, by means of electrical conductors, for example in the form of connecting foils, are known.
  • These connecting foils are connected in a connecting device in the form of a connection box or junction box to one or more electrical conductors of a connecting line, also called a solar connecting line.
  • a connecting device has an intermediate connection arrangement arranged in a connector housing, with multiple contacts, to which on the one hand one or more connecting foils of the solar module and on the other hand one or more electrical conductors of the connecting cable are connected.
  • such a connecting device in the form of a junction box usually contains one or more diodes, which are provided to prevent equalising currents between solar cells in sunlight and solar cells in shade, which supply different solar currents and solar voltages. With the aid of such so-called bypass diodes, the module can continue to work, even in partial shade and with correspondingly reduced power.
  • such a connecting device in the form of a junction box includes four metallic modules in the form of so-called conductor rails, for example to connect two solar connecting cables to the electrical connecting system of a solar module. These metallic modules are usually inserted and fitted manually, individually and in succession into a housing lower part of the junction box. Following this operation, appropriate bypass diodes (three in this case) are also usually fitted manually.
  • the conductor rails are each provided with tension springs, by which the diode connecting wires are connected electrically and mechanically to the conductor rail body.
  • the two connecting wires of the diodes are thus connected electrically and mechanically to the conductor rails, with the aid of metal clamps in the form of tension springs, which are placed on the conductor rails by machine.
  • larger tension springs using which corresponding electrical conductors of outward-leading solar connecting cables are contacted, are fitted on a number of conductor rails, in this case, for example, two conductor rails.
  • the electrical connecting system of the solar module is connected to the conductor rails by means of foil conductors, the contacting being carried out by means of foil springs, by which the foil conductors of the solar cells are connected to corresponding conductor rails or contacts.
  • a plastics material cover is latched onto the metallic modules which are produced and contacted in this way, and which are usually inserted manually, individually and in succession into the housing lower part of the junction box.
  • the conductor rails are fitted with the additional large tension springs, which for example are in the centre of the housing, whereas conductor rails on the outside are fitted only with the tension springs which are necessary for connecting the diode connecting wires.

  • the invention concerns a connecting device according to the features of Claim 1.
  • the invention also concerns a solar module with such a connecting device, according to the features of Claim 14.
  • the invention also concerns a method of producing a connecting device, according to the features of Claim 15.
  • the connecting device for connecting at least one external electrical conductor to an electrical connecting system of a photovoltaic solar module has a connector housing for arranging on the solar module, and at least one first contact which is arranged in the connector housing, with a first contact region for contacting the electrical conductor, and with a second contact region for connection to the electrical connecting system of the solar module, and also at least one second contact which is arranged in the connector housing, with a contact region for connection to the electrical connecting system of the solar module.
  • the first contact and the second contact each have at least one pluggable connecting mechanism.
  • At least one intermediate connecting arrangement for electrical connection of the first contact and second contact has a first contact portion, which is connected to the connecting mechanism of the first contact, and a second contact portion, which is connected to the connecting mechanism of the second contact.
  • the first and second contact portions are connected to each other via a separate electrical connecting element, which is contacted with the first and second contact portions.
  • the contact portions can be, for example, metal components which are extracted from a metal component such as a pressed screen (lead frame) and bent or otherwise formed as required, and which on the one hand are pluggable with the appropriate connecting mechanism of the first and second contacts, and on the other hand have connecting regions which are connected to the separate electrical connecting element.
  • the invention makes it possible to produce a connecting device for connecting an electrical connecting system of a photovoltaic solar module to, for example, a connecting cable, comparatively simply and inexpensively.
  • a further advantage of the invention is that if necessary the intermediate connecting arrangement, which is connected by means of the contact portions and via pluggable connecting mechanisms to the appropriate contacts, can be extracted as a functional unit from the connector housing, so that, for example, a defective intermediate connecting arrangement can be extracted from the connector housing and replaced by a functioning intermediate connecting arrangement.
  • the electrical connecting element is implemented as a diode component, which in particular is provided with diode connecting wires which lead out of the diode component on both sides, or as a short-circuit connection, in particular in the form of a wire.
  • the diode component is contacted with the first and second contact portions on the diode connecting wires, whereas in the case of a short-circuit connection the shorting jumper is contacted with the first and second contact portions, in particular, in the form of a wire.
  • the intermediate connecting arrangement has an electrically non-conducting fixing device, to which the first and second contact portions are fixed. In this way the stability of the intermediate connecting arrangement, and consequently of the functional unit formed by the first and second contact portions and the electrical connecting element, can be improved.

  • the stability of the intermediate connecting arrangement can be increased with a simultaneous saving in the use of material.
  • at least one of the first and second contact portions, preferably both, are locked on the fixing device, extrusion-coated by the fixing device or cast together with the fixing device.

  • a contact connection region is formed in the form of a leg, and is used to contact a diode connecting wire of a diode component to be contacted, or a wire of a shorting jumper.
  • Such formed contact connection regions are, for example, arranged on both sides of a contact portion, so the contact portion can be connected on both sides to an adjacent contact portion, via a diode component or a shorting jumper.
  • the contact connection region is formed for electrical contacting and mechanical fixing of the diode component or short-circuit connection, in particular for crimping the diode component or short-circuit connection to the contact connection region.
  • the contact connection region has V-shaped sections, to which the diode component or short-circuit connection can be crimped.
  • the contact connection region is in such a form, and arranged in such a way, that a diode connecting wire which is contacted with the contact connection region leads essentially straight out of the diode component, and is connected to the contact connection region.
  • the diode connecting wires of a diode component can essentially lead in a straight line, so that it is not necessary to angle them before contacting. This considerably reduces the danger of mechanical damage to the diodes in the assembly process.
  • the invention also makes it possible to place largely uniform contacts in the connector housing, so that the multiplicity of variants of contacts to be placed in the connector housing can be reduced.
  • a separate connecting contact element can be provided, and is used to connect the appropriate contact region of this contact to the electrical conductor of the connecting cable.
  • the connecting contact element is connected at a first end via a separable plug- and-socket connection to the appropriate contact region of the contact, whereas at another end it is formed for connection to the electrical conductor.
  • a contact can be extended modularly by means of the connecting contact element.
  • the pluggable connecting mechanisms of the first and second contacts are in such a form, and arranged in such a way, that each plug- and-socket connection is pluggable with the first contact portion and with the second contact portion in an approximately perpendicular direction to a base plane of the connector housing.
  • the intermediate connecting arrangement can comparatively easily be placed from above into the connector housing, or if required extracted from the connector housing from above.
  • the first and second contact portions are angled from a plane which runs approximately parallel to the base plane of the connector housing into an approximately perpendicular direction to the base plane of the connector housing. In the angled regions, the contact portions can be connected to the appropriate pluggable connecting mechanism of the contacts in the connector housing.
  • An embodiment of a method of producing a connecting device according to the principles of this invention as described above has, in particular, the following steps:
  • the first and second contacts, and other contacts if any, are arranged in the connector housing.
  • the contact portions of the intermediate connecting arrangement are produced from a metal component, the contact portions being formed so that they are in continuous form over any connections of the metal component.
  • at least one electrical connecting element for example in the form of a diode component or a shorting jumper, is arranged between a first and a second of the contact portions which are arranged adjacently to each other, and combined with the first and second contact portions into a functional unit.
  • at least some of the connections of the metal component between a number of contact portions are removed, to extract the functional unit.

  • the connecting contact element has a shape (shown in Fig. 1OA without a tension spring) which for example is suitable for arrangement of a tension spring 25 according to Fig. 1OB, similar to the contact region 51 of the contact element 20 according to Fig. 8.
  • Fig. 11 shows how the two outer contacts 21 and 24 can each be extended by a connecting contact element 70, by the contact blade 62 of the connecting contact element 70 being connected to the Faston connection 61 of the contact 20 in its contact region 51.
  • Fig. 7 shows a detailed representation of the embodiment of the connecting device according to Fig. 2, showing in more detail how the contact portions 41 to 44 of the functional unit 4 are pluggably connected to the corresponding contacts 21 to 24.
  • Fig. 7 shows how the contact portion 41 is introduced into the Faston connection 61 of the contact 21.
  • the plug-and-socket connection of the contact portions 41 to 44 to the contacts 21 to 24 can be closed, and separated again, in an approximately perpendicular direction to the base plane of the housing floor 15 of the connector housing 10.
  • the contact portions 41 to 44 are angled from a plane which is approximately parallel to the base plane of the housing floor 15, as is illustrated in the cross-section of Fig. 7 on the basis of the contact portion 41 , for connection to the corresponding contact in an approximately perpendicular direction to the base plane of the housing floor 15.
  • the region of the contact portions 41 to 44 which is parallel to the housing floor 15, rests on the region (for example in the contact region 51) of a corresponding one of the contacts 21 to 24, which region is also parallel to the housing floor 15.
  • the Faston connection 61 is in such a form that the locking elements 14 can engage in a projecting region of the Faston connection, to lock the functional unit 4 in the connector housing 10. This is shown, in particular, in Fig. 7, according to which the locking elements 14 engage on the convex contact regions of the Faston connections.
  • Figs. 2 and 7 show an embodiment in which the diodes of the functional unit 4 face the connecting ducts 11 for the electrical conductors of the connecting cable(s) 2.
  • the diodes are arranged on the opposite side, and therefore face the housing opening 12 for the foil conductors of the solar module.
  • the functional unit 4 without design changes being necessary, is rotated by 180° around the vertical axis, the contacts 21 to 24 being previously connected to the corresponding connecting foils of the solar panel.
  • the contacts 20 or 21 to 24 can, for example, be produced as punched bent parts in a long or short version, and in principle used variably and/or combined with each other as required.
  • the long version is described in more detail, for example, in Fig. 8, whereas the short version can be according to Fig. 9A or Fig. 9B.
  • suitable connecting mechanisms such as socket contours (for example to form a Faston connection, as described) or pin contours can be formed, to produce a corresponding plug- and-socket connection to the functional unit 4.
  • the affected defective diode can be located and separated out on site.
  • a repair set consisting of the corresponding diode and two tension springs can be made available.
  • the two tension springs are mounted on the contact portions, which are implemented as flat plugs (opposite side of the plug contour). Using them, the replacement diode can be reconnected electrically and mechanically to the contact portions which were previously connected to the defective diode.
  • the whole functional unit 4 can very quickly be removed from the connector housing 10 and replaced with another functional unit, without the electrical conductors having to be separated from connecting cables, or the foil conductors of the solar panel within the connector housing having to be separated electrically or mechanically from the contacts of the connector housing. Instead, a defective functional unit which has been removed can be repaired in a workshop, irrespective of time and place.
  • Advantages of the invention are thus clearly reduced costs for production of the functional unit or intermediate connecting arrangement compared with the connection technology described in the introduction, and also a component reduction by the omission of tension springs for fixing the diodes and the associated protective covers, simplification of the design of metal components for producing the contacts of the connector housing and producing the contact portions of the functional unit, a saving of material and not least a saving of assembly costs. Also, in the case of a diode defect, the speed of on-site servicing can be increased. In particular, a cost reduction is possible by metal components of a very simple form and by very good use of the material of a metal strip.
