description

Field of the invention

The invention relates to a compact and simple

manufactured edge connector for a photovoltaic solar module.

Background of the invention

Photovoltaic solar modules are available in the meantime in a variety of designs on the market. In addition to the most commonly used framed glass-foil modules for rooftop or open space installation are those of particular interest, which are constructed in tile form and can be used in particular for the integration of buildings as façade or roof elements.

Such a tile or plate-shaped solar module typically comprises a sandwich-like, multilayered

Construction with a translucent top layer facing towards the light source (sun), a back cover plate, in a gap

arranged solar cells for generating electrical energy from sunlight and an outer frame on a

front edge of the solar module, which connects the cover layer and the cover circumferentially tightly together.

For electrical contacting of the solar cells with

Connecting leads and / or other solar modules typically become conductor-bounded conductor bands laterally led out of the gap or guided to the region of the front edge, so that they can be connected in each case with an edge connector. To avoid triggered by reverse currents

Damage to the solar modules, so-called hot spots, the

especially with shadowing and partial shading of individual solar modules of a photovoltaic generator

It is known, above all, for the framed glass-film modules and also for glass-film modules, bypass and / or stranded diodes, that is to say quite generally

Return current diodes, use, which have a passage and a reverse direction for the flow of current. The

Bypass diodes are typically housed in the rear-mounted junction box.

Due to the smallest possible spacing of the plurality of solar modules from each other, the arrangement of such a circuit in an edge connector but not readily possible.

General description of the invention

The invention has for its object to provide a

Edge connector to provide, which is compact in size and easy to install.

Another object of the invention is to

Provide photovoltaic solar module with two edge connectors, wherein the edge connectors are connected to each other via an edge connector line. The object of the invention is solved by the subject matter of the independent claims. Advantageous developments of the invention are defined in the subclaims. According to the invention, an edge connector comprises

dielectric edge connector housing with a lateral mounting tab. By means of the mounting bracket of the

Edge connector at a front edge of the

Solar module to be attached. Preferably, the

Edge connector on the side of the solar module in the area of

Attached external frame by the side mounting tab is glued directly during the lamination process in the laminate of the solar module, or by the side mounting tab in a gap, a slot or a

Opening the outer frame in particular between the

front cover layer and the back cover plate is inserted and glued there. But even with such a solar module without outer frame, in particular a frameless glass-glass module, the edge connector can be attached to the front edge of the solar module by the side mounting tab of the edge connector is glued directly during the lamination process in the laminate of the solar module, or by inserting the lateral mounting tab into the slot in the front edge between the front cover layer and the rear cover plate of the solar module. The

Attachment to a frameless glass-glass module is preferred for the mounting of the edge connector, since in this case no outer frame is present, which is only to prepare for the installation of the edge connector. The edge connector has a dielectric

Edge connector housing on which the electrical

accommodates conductive components of the edge connector and at the same time has a longitudinal mounting tab for attachment of the edge connector to the solar module. The

Edge connector housing may be made in one piece or in several pieces and / or by injection molding.

On the side of the edge connector is a first

Cable connector for releasably connecting the

Connecting cable arranged on the edge connector, by means of which an electrical connection of the connecting cable to the solar module can be produced. Opposite the first cable connector, a second cable connector is disposed on the edge connector and electrically connected to the first cable connector. To the second cable connector may be limited to the solar module edge connector line or a second

Connecting cable to be connected.

The opposite arrangement of the first and second cable connector, in particular on the opposite end faces of the edge connector allows the most compact and space-saving construction of the edge connector.

Disposed between the first and second cable connectors is a conductor band terminal which is electrically connected to the first and second cable connectors. The conductor strip connecting element provides the electrical

Connection of the edge connector with the solar cells of the solar module ago. On the module side, the solar module can have contact areas, to which in each case one on the edge connector

connected conductor strip can be connected. In other words, so can a pre-assembled

Edge connector, which already has a prior to installation in the solar module connected to the conductor strip connection element conductor strip, directly to the solar module

especially during the lamination process. Such a prefabricated edge connector is particularly preferred in the case of an overmolded

Edge connector.

Alternatively, the edge connector can also immediately upon installation to a protruding from the solar module

Conductor band to be connected.

The edge connector is constructed so compact that after mounting on a solar module substantially only a cylindrical or rod-shaped portion of the edge connector, comprising the first and second cable connector and the conductor strip connection element, emerges directly from the solar module. The connector housing accordingly comprises the oblong section arranged axially aligned on the end face of the solar module and the longitudinal section

Mounting tab, which protrudes in the mounted state in the solar module. This can be for the electrical

Installations required construction area can be reduced to a minimum and thus a larger number of

Solar modules are installed in a specified area. In addition, such a compact edge connector reduces the risk that the edge connector broken off when improper handling, so destroyed. Last but not least reduces the compact geometry of the

Edge connector also the production costs, since the

Edge connector housing over the prior art can be further reduced.

Another beneficial influence on the

Production processes lies in the preferably selected rounded, edgeless geometry of the edge connector which, even with the use of thinner solar modules in relation to the size of the edge connector, which can be achieved in particular by the use of thinner glasses, protects the laminator membranes in the lamination process.

The conductor strip connecting element of the edge connector preferably comprises an electrically conductive sleeve, for example a metal sleeve. The electrically conductive sleeve of the conductor strip connection element preferably connects the oppositely arranged first and second

Cable connector directly electrically to each other, so that no further electrical components between the cable connectors and the conductor strip connection element must be arranged. The electrically conductive sleeve thus preferably extends within the edge connector housing from the first cable connector to the second cable connector in a direction along one edge of the first cable connector

photovoltaic solar module is aligned and connects directly the first cable connector of the edge connector with the second cable connector of the same edge connector. This can further reduce production costs. Preferably, the conductor strip emerging from the solar module or projecting from the edge connector into the solar module is electrically connected to the electrically conductive sleeve

contacted. For contacting the conductor strip with the electrically conductive sleeve, the conductor strip is wrapped in one embodiment around the sleeve and preferably welded to the sleeve.

In other words, in the edge connector housing a continuous metal sleeve can be arranged, which is exactly one conductor band of the photovoltaic solar module with both the first cable connector and with the second

Cable connector directly electrically connects without other electrical components, such as in particular

Semiconductor devices in which edge connectors are needed. The edge connector thus connects by means of this metal conductor connection element exactly one and not both of the electrical poles of the photovoltaic

Solar module with the cable connectors of the edge connector.

The first and second cable connectors are preferably configured distinguishable from one another, so that a faulty connection and / or polarity reversal of lines can be avoided. A distinguishable embodiment may have two mutually paarbare versions or even several embodiments, if a higher degree of distinctness of the cable connector is desired.

In one embodiment of the invention, the first and second cable connectors inside

Berührsicherungshülse a contact point for electrical contact with a line to be connected, in particular the connection line and / or the edge connector line. The contact point can therefore be carried out safe to touch, since they are of the

Berührsicherungshülse is housed.

Furthermore, the Berührsicherungshülse may have a sealing element, so that the contact point is made waterproof in the connected state of the cable connector. Preferably, the first and / or second cable connector is designed as a connector. The to be connected

Lines, e.g. the connection line or the

Edge connector lead, have in this case to paarbare connector.

The mounting tab of the edge connector may have openings or openings to increase the adhesive force of the lamination or sealing compound used in the assembly of the edge connector, so that the surface of the

Mounting tab does not form a closed surface and the spaces in the openings of the mounting bracket with

Lamination or sealant can be filled, whereby the bond, the front-side cover layer with the

back cover also connects in the area of the mounting bracket. Preferably, the lamination or sealing material is used for bonding the edge connector, which is also used to connect the front and the back

Covering layer is used, in particular, the

Edge connector in the context of the lamination process of the solar module adhesively connected to the solar module, so that when mounting the edge connector, an additional step can be saved. An inventive photovoltaic solar module for

Generation of electric power from sunlight includes a first and a second on the solar module

mounted edge connector to connect a first and second electrical power supply line to the solar module.

The edge connectors of the solar module each have a dielectric edge connector housing with a

longitudinal mounting tab on, so that the

Edge connector at a front edge of the

Solar module can be fastened. Both are preferred

Edge connector arranged on the same side of the solar module.

In other words, two mutually spatially spaced edge connectors, each with a separate edge connector housing are arranged on the photovoltaic solar module, so that an electrical pole of the photovoltaic solar module can be connected to each of the edge connector. The two edge connectors of the photovoltaic solar module are thus designed as a single pole. Each edge connector of the solar module each comprises a first cable connector for connecting the first or

second strand connection line with the solar module, which is mounted laterally on the edge connector. A second cable connector is respectively attached to the edge connector opposite the respective first cable connector and electrically connected to the respective first cable connector. By means of each second Cable connector can be mounted on the solar module limited edge connector cable. Between the first and second cable connector of each

Edge connector is a conductor strip connection element arranged for electrical connection with a respectively emerging from the solar module or already

prefabricated on the conductor strip connection element mounted conductor strip.

The edge connector line of the solar module has in one embodiment, a bypass diode and is connected to the respective second cable connectors of the edge connector, so that the solar module on the

Edge connector lead in case of failure, such as caused by shading, or generally in reverse currents, is electrically bypassed. The arrangement of the bypass diode in the edge connector line proves to be extremely advantageous because the

Edge connector lead in case of failure of the bypass diode is easily replaceable. Furthermore, on the

Edge connector cable with bypass diode can be omitted if it is to be expected that with the bypass diode

fused solar panel does not like faults

shadowing in particular will be affected. In other words, the bypass diode is outside the

Edge connector housing and as part of

Edge connector line arranged.

According to the invention is also a system of a variety of solar modules for building a

Photovoltaic generator, wherein the solar modules comprise a first and a second edge connector to a first or to connect the second electrical line connection line with the respective solar module. First and second edge connectors are preferably fastened to the peripheral frame of the respective solar module.

The edge connectors of the respective solar module have a dielectric edge connector housing with a lateral mounting tab, so that the edge connectors can be fastened to an end edge of the solar module.

Preferably, both edge connectors are arranged on the same front edge of the solar module.

Each edge connector of the solar module comprises a first cable connector for connecting the first and second strand connection line to the solar module, which is mounted laterally on the edge connector. A second

Cable connector is attached to the edge connector opposite the first cable connector and electrically connected to the first cable connector. By means of the second cable connector can be mounted on the solar module limited edge connector cable. Between the first and second cable connector of the edge connector, a conductor strip connecting element is arranged for electrical connection to the conductor strip.

Each solar module of the system from a variety of

Solar modules can be equipped with an edge connector cable with a bypass diode. Accordingly, the respective second cable connector of the edge connector of a solar module is prepared to the detachable

Connect edge connector line thereto, so that the respective solar module via the edge connector line in Error case, or generally at return currents, is electrically bypassed. Preferred is in the system of a

Variety of solar modules at least a part of the solar modules equipped with the edge connector line, especially in the part in which shadowing can be expected. Thus, the mostly expensive bypass diodes in the

Detailed description of the figures

Figure 1 shows an edge connector 2 according to the invention for attachment to a photovoltaic solar module, which a first cable connector 4, a second

Cable connector 6 and an edge connector housing 8 with a mounting bracket 10 has. The edge connector 2 can be fixed to the solar module 16 by means of the mounting tab 10, which is insertable into an end edge 14 (see FIG. 8) of a solar module 16. The

Mounting tab 10 is particularly designed in one piece and has bulges at the edges, so that it extends further into the laminate of the solar module without having a larger entrance surface in the solar module. The mounting bracket 10 can be glued into the solar module 16, wherein to increase the adhesion holes 11 are provided in the mounting bracket 10. The protruding from the solar module 16 part of the edge connector 2 is in the embodiment shown elongated or rod-shaped and / or rounded or edgeless. The from the solar module 16

Bypass diode 32 may include. The second cable connector 6 comprises, in the embodiment shown, an oblong, the cable contact enclosing Berührsicherungshülse 29, which accommodates the cable contact, so that it can not or only very hard to touch even when not plugged. On the Berührsicherungshülse 29 of the second cable connector 6, a sealing ring 7 is in the example shown outside the center, which closes the cable contact in the inserted state watertight and thus protects the cable connector from penetrating dust, dirt and water. In the embodiment shown, the first contact (26, see Fig. 4) of the first cable connector 4 as a male cable connector, so as a plug, and the second contact (28, see Fig. 2) of the second cable connector 6 as a female cable connector, ie as Bushing, executed.

The first cable connector 4 is disposed opposite to the second cable connector 6, in particular as shown in Fig. 1 axially aligned opposite. in the

mounted state, the first cable connector 4 and the second cable connector 6 are therefore arranged adjacent to parallel to the front edge of the solar module 16, to which the edge connector 2 is attached to the solar module. First cable connector 4 and second cable connector 6 are preferably linearly linear, extending along an axis parallel to the front edge of the

Extend solar module.

In addition, the inventive compactness of the structure of the edge connector 2 can be further increased by the fact that the bypass diode 32 outside the

Edge connector housing 8 is arranged. Such

Arrangement of the bypass diode 32 outside the

Edge connector housing 8 allows next to the small Type of interchangeability of the bypass diode 32 in a maintenance case.

photovoltaic solar module 16 is mounted. The

Mounting tab 10 of the edge connector 2 is between the front-side cover layer 18 (see Fig. 8) and the

back cover plate 20 (see Fig. 8) of the solar module 16 inserted so that it is not visible in a plan or possibly through a glass surface through.

A conductor strip 22 of the solar module 16 is led out laterally out of the solar module 16 and attached to the edge connector 2. In the case of a prefabricated

Edge connector 2, the conductor strip 22 is already part of the edge connector 2 and is together with the

Edge connector 2 attached to the solar module, in particular contacted to contact areas of the solar module. For this purpose, the conductor strip 22 of the prefabricated edge connector 2 in the lamination process of the solar module 16 with a

Conductor or the flexible flat conductor band of the

Solar module 16 contacted, e.g. welded or soldered.

To improve the adhesive force of the edge connector 10 holes are used in the mounting bracket, which allows direct contact of the present on the front cover layer 18 lamination or sealant with that which is located on the back cover plate 20.

Figure 8 shows a side view of the on the solar module 16 between the front-side cover layer 18 and the

rear cover plate 20 attached

The electrically conductive sleeve 24 extends within the edge connector housing 8 between the first and second plug contact elements 26, 28. The solar cells of the solar module 16 are also arranged between the layers 18, 20, so that they are protected from environmental influences. The edge connector 2 is advantageously just so wide that it is substantially adapted to the thickness of the solar module 16 and this only slightly exceeds or even falls below. This allows an additional height only for the electrical installation of the solar modules 16

be avoided. FIG. 9 shows a plan view of an embodiment of an edge connector 2, wherein the dielectric edge connector housing 8 has been omitted for a better overview. A first contact 26, arranged in the first cable connector 4, provides the electrical contact of the edge connector 2 with a first connecting line 24a or a

Generator line 24b ago. A second contact 28, arranged in the second cable connector 6, if necessary, establishes contact with an edge connector line 12. The

between the first contact 26 and the second contact 28 arranged conductor strip connection element 30 provides the electrical contact of the edge connector 2 with the

Conductor band 22 ago, and thus also the electrical contact of the first connecting line 24a and the

Generator line 24 b with the solar module 16.

The first contact 26 is thus preferably axial

opposite to the second contact 28 of the

Cable connector 2, wherein between the first contact 26 and the second contact 28, the

Conductor strip connection element 30 is arranged. The

Conductor strip 22 occurs perpendicular to the end edge of the solar module 16, and as shown in Fig. 9 is preferred Also perpendicular to the axis, which is formed by the first contact 26 and the second contact 28, from the

Solar module 16 out and attached to the conductor strip connection element 30, i. especially entangled, laid and / or welded.

Edge connector 2 can therefore be punched in one piece

and / or shaped. In the event that a molded edge connector housing 8 (for example, Fig. 2 and 4) is to be used, the edge connector 2 shown in FIG 9 shows in particular the complete of the spray mass

enclosing part of the edge connector.

Figure 10 shows an end view of a

Edge connector 2 of FIG. 9 and illustrates the

Compactness of the edge connector 2, in particular in the direction corresponding to the thickness of the solar module.

FIG. 11 shows a plan view of an embodiment of a photovoltaic solar module 16 with a first one

Edge connector 2a and a second edge connector 2b, which are arranged on an end edge 14 of the solar module 16. The attachment of the edge connector 2a, 2b to the solar module 16 takes place by means of a gluing of the mounting tab 10 of the edge connector housing 8 between the front-side cover layer 18 and the back side

Cover plate 20. To improve the adhesion of the

Edge connector 2 to the solar module 16 are, as well as in Figures 1, 2, in the mounting bracket 10th

Holes 11 present, which allows a direct contact of the present at the front-side cover layer 18 lamination or sealant with that part which is located on the rear cover plate 20. To the first cable connector 4 of the first edge connector 2a, the first strand line 24a is connected and contacted to the first contact 26 of the first edge connector 2a. To the first cable connector 4 of the second edge connector 2b, a second strand line 24c is connected.

The solar module 16 has two conductor strips 22, wherein in each case an edge connector 2a, 2b contacts a conductor strip 22. This ensures that the first connecting line 24a or the second connecting line 24c in each case only contacted with a conductor strip 22 of the solar module 16, so that the solar module 16 is always traversed by the current flow. The edge connectors 2a, 2b are thus single-pole edge connectors. A reverse current diode is shown in the embodiment of FIG.

Figure 12 shows an edge connector lead 12 for connecting the second cable connector 6 of the first edge connector 2a to the second cable connector 6 of the second one

Edge connector 2b, which comprises a reverse current diode 32, so that the solar module 16 in the fault or reverse current case can be electrically bypassed by the return current diode 32 of the edge connector line 12. The edge connector line 12 is connected by means of the line connector 6a, 6b to the respective second cable connector 6 of the edge connector 2a, 2b

connected. The integration of the bypass diode 32 in the circuit of the solar module 16 may damage this Solar module 16 then prevent when reverse currents occur. However, when planning the installation of the

Solar module, or the planning of a photovoltaic generator, are excluded that return currents can occur in the solar module, in some solar modules or in all solar modules, the edge connector line 12 can be saved. The edge connector lead 12 may also allow for cost effective replacement of a defective reverse current diode.
