Description

Technical Field

[0001] The present invention relates to a basic element for an at least two-part overvoltage protection device, the basic element having a carrier rail receptacle for accommodating a potential-carrying carrier rail, a first receptacle for accommodating a first electrical conductor, a second receptacle for accommodating a second electrical conductor, and a protective element receptacle for accommodating an overvoltage protection element. Furthermore, the present invention relates to an overvoltage protection device having at least one basic element and at least one overvoltage protection element, the basic element having a carrier rail receptacle for accommodating a potential-carrying carrier rail, a first receptacle for accommodating a first electrical conductor, a second receptacle for accommodating a second electrical conductor, and a protective element receptacle for accommodating an overvoltage protection element. Background Art

[0002] The aforementioned basic elements of overvoltage protection devices and corresponding overvoltage protection devices have been known for many years and are used to protect electronic and electrical devices from overvoltages. Overvoltage protection devices can be used in various applications, with a distinction often being made between overvoltage protection devices for protecting power supply networks and overvoltage protection devices for protecting signal lines or low-voltage lines. For the present invention, the type of voltage to be transmitted by the overvoltage protection device is not important.

[0003] The voltage and / or current and / or electrical power to be transmitted by the overvoltage protection device is fed into the overvoltage protection device via a first receptacle for accommodating a first electrical conductor, i.e., fed from the unprotected side, and is fed out of the overvoltage protection device via a second receptacle for accommodating a second electrical conductor, i.e., to the side protected against overvoltage. The term "electrical conductor" is to be understood broadly here. As is known in the prior art, the first and second electrical conductors are respectively the ends of insulated or partially deinsulated metal conductors. Spring terminals or insulation displacement terminals, for example, are then provided in the first and second receptacles—i.e., as components of the base element—to secure and electrically contact the introduced ends of the metal conductors.

[0004] It is also known from the prior art that a base element can accommodate multiple first conductors via multiple first receptacles, and similarly, multiple second conductors via multiple second receptacles. Regardless of the number of first conductors and second conductors, an electrical connection element is implemented between the first receptacle and the second receptacle for transmitting an electrical signal (in the form of a voltage) from the first receptacle to the second receptacle.

[0005] This includes overvoltage protection devices and corresponding basic elements therefor, wherein an electrical carrier rail contact element is formed in the carrier rail receptacle for electrically contacting the carrier rail when the carrier rail is received by the carrier rail receptacle. The carrier rail is typically designed as a metal profile rail, often as a so-called "hat rail." If the carrier rail is provided with an electrical potential, this potential is usually the ground potential of the electrical system. This potential of the carrier rail is then often also used to implement overvoltage protection as dielectric strength protection between the signal conductor and ground.

[0006] The overvoltage protection element itself carries the electrical protective components required for overvoltage protection. To this end, when the overvoltage protection element is accommodated in the protection element receptacle, the electrical connection element and the electrical load rail contact element are at least indirectly electrically contacted via corresponding electrical contact elements of the overvoltage protection element. To limit overvoltages and dissipate surge currents, a low-impedance electrical connection is established between the electrical contact elements of the overvoltage protection element when an overvoltage occurs between them.

[0007] Multi-pole system cables or system lines are often used in control and signaling systems to route a number of different signals. It's easy to see that routing the individual signal conductors to the corresponding overvoltage protection devices and their base components is complex and error-prone. In addition to multi-pole system cables, multi-pole plug-in connector systems are also often available for disconnecting and connecting multi-pole cables, in which the connector components engage with each other in a form-fitting manner. Applications often involve existing systems, where retrofitted operating components, such as the overvoltage protection devices discussed here, need to be introduced into one or more signal paths. Depending on the application, it's preferable to not interfere with the existing wiring, also for formal licensing or safety reasons. For example, if a lightning protection device is to be installed to protect the insulation strength of an existing system, the existing cable routing must be retained as much as possible. Cable connections should not be opened or completely loosened and then reconnected in a different manner. Only minimal intervention is necessary in order not to jeopardize the existing approvals of the electrical installation. Summary of the Invention

[0008] The object of the present invention is therefore to specify a basic element for an overvoltage protection device and also a corresponding overvoltage protection device which can be easily installed, in particular in existing control and signaling systems.

[0009] The aforementioned object is primarily achieved in the basic element described at the outset by virtue of the fact that the first and second receptacles are designed to receive electrical connector components or adapter connector components for an electrical connector. These electrical connector components are often components of a multi-pole electrical connector, wherein the connector components then engage one another in a form-fitting manner. The first and second receptacles can also be designed to receive connector components of different connectors; they do not necessarily have to be receptacles of corresponding connector components.

[0010] However, in a preferred embodiment, the first and second receptacles are designed to accommodate corresponding electrical connector parts, i.e., electrical connector parts that engage with each other in a form-fitting manner, wherein these electrical connector parts naturally have plug contacts via which an electrical connection can be established. The corresponding connector parts are typically corresponding male / female electrical connector parts.

[0011] Therefore, electrical conductors in the form of connector parts of an electrical connector are no longer inserted directly into the first and second receptacles designed according to the present invention, but rather into multi-pole plug-in connector systems. The basic element of the overvoltage protection device according to the present invention and an overvoltage protection device equipped with such a basic element can therefore be easily integrated into the wiring of existing installations. To do this, the existing cabling must simply be interrupted at the appropriate locations by opening / separating the existing system plug-in connectors as required. The basic element according to the present invention is inserted by inserting the connector parts into the corresponding first and second receptacles of the basic element, thus closing the signal circuit. No intervention in the wiring (opening of screw contacts, spring contacts, or insulation displacement contacts) occurs.

[0012] As explained at the outset, there are many connectors that, for example, correspond to different standards or can be manufacturer-specific. To avoid having to design the base element individually for each different connector type, the present invention also provides that the first and second receptacles are configured to accommodate adapter connector components for electrical connectors. These adapter connector components are configured on one connection side so that they can be accommodated in the first and / or second receptacles of the base element. From the second connection side, the adapter connector components are configured so that they can accommodate the corresponding electrical connector components of the connector system used in the specific case. This allows a unified base element to be used for different devices with different connector systems.

[0013] In a particularly preferred embodiment of the base element, the base element comprises a housing, wherein the first and second receptacles are formed on opposite end faces of the housing, and the housing is open on the sides pointing in the direction of extension of the support rail. This makes it relatively easy to equip the housing with corresponding electrical components, such as, for example, electrical support rail contact elements and electrical connection elements for transmitting electrical signals from the first receptacle to the second receptacle. In this context, another advantageous embodiment provides that the base element comprises a closing element for closing the open sides of the housing. This allows for electrical insulation of the interior of the base element without sacrificing the advantage of easy access to the interior of the base element.

[0014] In another advantageous embodiment, the first receptacle and the second receptacle are multi-polar, in particular bi-polar, in design. Thus, a plurality of signal lines and signal voltages in the basic element can be provided with overvoltage protection.

[0015] Another preferred embodiment of the basic element provides for the receptacle of the overvoltage protection element to be multi-pole, in particular three-pole. At least one potential must be transmitted to the overvoltage protection element, between which overvoltages must be determined and dissipated. Therefore, at least two potentials are transmitted to the overvoltage protection element via the receptacle for the overvoltage protection element, i.e., at least two poles. A three-pole receptacle design is suitable, for example, if two signals are to be transmitted through the basic element and, in the process, the overvoltage must be dissipated to a grounded support rail.

[0016] The basic element according to the invention is particularly preferably used for dielectric strength protection, ie for protecting each individual signal line and grounding device, in particular a support rail.

[0017] The present invention also generally relates to an overvoltage protection device in which the described basic element and also the described overvoltage protection element are used. The present invention therefore generally relates to an overvoltage protection device having at least one base element and at least one overvoltage protection element, wherein the base element has a carrier rail receptacle for accommodating a potential-carrying carrier rail, a first receptacle for accommodating a first electrical conductor, a second receptacle for accommodating a second electrical conductor, and a protection element receptacle for accommodating the overvoltage protection element, wherein an electrical connection element for transmitting an electrical signal from the first receptacle to the second receptacle is implemented between the first receptacle and the second receptacle of the base element, wherein an electrical carrier rail contact element is formed in the carrier rail receptacle for electrically contacting the carrier rail when the carrier rail is accommodated by the carrier rail receptacle, wherein when the overvoltage protection element is accommodated in the protection element receptacle, the electrical connection element and the electrical carrier rail contact element are at least indirectly electrically contacted via corresponding electrical contact elements of the overvoltage protection element (and when an overvoltage occurs between the electrical contact elements in the overvoltage protection element, a low-impedance electrical connection is implemented between the electrical contact elements for dissipating the overvoltage), and wherein the first receptacle and the second receptacle are designed to accommodate an electrical connector part or an adapter connector part for the electrical connector part.

[0018] All previous explanations regarding the basic element and also regarding the overvoltage protection element also apply to the overvoltage protection device mentioned here.

[0019] A particularly advantageous overvoltage protection device is distinguished by the fact that multiple base elements are aligned side by side along the extension direction of the support rail, and that the first and / or second receptacles arranged side by side are provided with an integral connector component and / or an integral adapter connector component that can be inserted integrally into the first and / or second receptacles arranged side by side. The connector component or adapter connector component has the advantageous property that it can be used with multiple base elements arranged side by side. The connector component or adapter connector component is therefore typically multi-pole. The adapter connector component can therefore also accommodate multi-pole connector components of the type of connector being used in the installation. Thus, a modular overvoltage protection device can be constructed using multiple base elements of the same type, with the integral connector component and / or integral adapter connector component being inserted into the first and / or second receptacles arranged side by side of the overvoltage protection device. When a connector part or an adapter connector part is said to be integral, this does not mean that the connector part or the adapter connector part consists of a single structural element, but only that the connector part or the adapter connector part is the only element that can be manipulated by itself and can be inserted or removed as a whole.

[0020] In a very particularly preferred embodiment, five base elements are arranged next to one another and are designed to accommodate a ten-pole connector part or adapter connector part.

[0021] According to another embodiment, the adapter connector part is designed as a plug connector on the side facing away from the first or second receptacle. In particular, the plug connector on the side facing away from the first or second receptacle is a different type of plug connector than the plug connector on the side of the adapter connector part facing the first or second receptacle. The adapter connector part thus establishes a match between two different types of plug connectors. The side facing the first or second receptacle can then, for example, be a manufacturer-specific connection for the base element or the corresponding overvoltage protection device, while the side facing away from the first or second receptacle can be another plug connector, such as a conventional mounting plug connector. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In detail, there are now several possibilities for improving and designing the basic element according to the invention for an overvoltage protection device and a corresponding overvoltage protection device according to the independent claims. This is illustrated in conjunction with the illustrations in the following figures. In the figures:

[0031] In all Figures 1 to 8 , a basic element 1 or parts of a basic element 1 for a two-part overvoltage protection device 2 is shown. The basic element 1 has a carrier rail receptacle 3 for accommodating a potential-carrying carrier rail 4. Each basic element 1 comprises a first receptacle 5 for accommodating a first electrical conductor 6 and a second receptacle 7 for accommodating a second electrical conductor 8.

[0032] The figures do not show a basic element as known from the prior art. In the prior art, the first and second electrical conductors are typically the ends of metal wires, either with or without insulation removed, with the first and second receptacles often comprising spring terminals or insulation displacement terminals. This is solved in a completely different way in the illustrated basic element 1, as will be explained below.

[0033] All basic elements 1 have a protection element receptacle 9 for accommodating an overvoltage protection element 10 .

[0034] Depend on Figure 1 、 7As is apparent from Figures 8 and 9 , electrical connection elements 11 , 11 a, 11 b are implemented between the first receptacle 5 and the second receptacle 7 for transmitting electrical signals from the first receptacle 5 to the second receptacle 7 .

[0035] exist Figure 1 , 5, 7 and 8, it can be seen that an electric bearing rail contact element 12 is constructed in the bearing rail receiving portion 3 for electrically contacting the bearing rail 4 when the bearing rail 4 is received by the bearing rail receiving portion 3. Therefore, the potential of the bearing rail 4 can be tapped by the bearing rail contact element 12. The overvoltage protection element 10 is responsible for conducting away the detected overvoltage. For this purpose, when the overvoltage protection element 10 is received in the protection element receiving portion 9, the electrical connection elements 11, 11a, 11b and the electric bearing rail contact element 12 are contacted by the corresponding electrical contact elements 13, 14 of the overvoltage protection element 10, which Figure 1 When an overvoltage occurs between the electrical contact elements 13 , 14 in the overvoltage protection element 10 , a low-impedance electrical connection 15 is created between the electrical contact elements 13 , 14 via the gas arrester, and the overvoltage is dissipated.

[0036] A particularity of the illustrated basic element 1 and also of the overvoltage protection device 2 is that the first receptacle 5 and the second receptacle 7 are designed to receive electrical connector parts 16a, 16b or adapter connector parts 17a, 17b for the electrical connector parts 16a, 16b. Figure 1 Schematically illustrates an application scenario in which the first and second electrical conductors 6 and 8 are in the form of connector parts 16a and 16b. The connector parts 16a and 16b are corresponding electrical connector parts 16a and 16b with plug contacts, that is, they engage with each other in a form-fitting manner. These are corresponding male and female electrical connector parts 16a and 16b. The first receptacle 5 is designed so that it can easily accommodate the electrical connector part 16a, and the second receptacle 7 is designed so that it can easily accommodate the electrical connector part 16b. Therefore, it is no longer necessary or desirable to insert the electrical conductors 6 and 8 in the form of pure wires into the first and second receptacles 5 and 7. Rather, the first and second receptacles 5 and 7 are adapted to accommodate the connector parts 16a and 16b, as are found, for example, in plug-in connector systems for electrical devices, particularly control and signaling systems.

[0037] exist Figures 2 to 7 1 and 2 show a base element 1, wherein the first receiving portion 5 and the second receiving portion 7 of the base element are configured to receive adapter connector parts 17a, 17b for electrical connector parts 16a, 16b. Figure 2 and Figure 3 . The adapter connector parts 17a, 17b are, of course, designed accordingly for the respective first receptacle 5 or second receptacle 7 on the side facing away from the first receptacle 5 or second receptacle 7. However, on the side facing away from the first receptacle 5 or second receptacle 7, the adapter connector parts 17a, 17b are designed differently, namely for a type of plug-in connector already installed in the device into which the overvoltage protection device 2 or the associated base element 1 is to be embedded. This makes it very simple to use one and the same overvoltage protection device 2 or the corresponding base element 1 for completely different connection situations and plug-in connector types, without having to adapt the first receptacle 5 or second receptacle 7 to the given conditions of the respective electrical device in each case. The adapter connector parts 17a, 17b used only need to be adapted to the manufacturer-specific first receptacle 5 or second receptacle 7 on their side facing the base element 1.

[0038] It can be seen in the figures that the basic element 1 has a housing 18. The housing 18 is an insulating material housing. The first receptacle 5 and the second receptacle 7 are formed on opposite end faces of the housing 18. Figure 2 and Figure 7 As can be seen in FIG, the housing 18 is designed to be open on the sides pointing in the extension direction of the support rail 4. When it is said that "certain sides point in the extension direction", this refers to the surface normals on these respective sides. By making the housing 18 open on the respective sides, the required electrical components can be introduced very easily into the interior space of the housing 18. Figure 3 , 5 and 6 that the open sides of the housing 18 of the basic element 1 are closed by closure elements 19. Consequently, electrically conductive components in the interior of the housing 18 are no longer accessible without problems.

[0039] exist Figures 2 to 7In all the exemplary embodiments, the first receptacle 5 and the second receptacle 7 are multi-pole, that is, two-pole. This allows two signal lines to be monitored for overvoltage in the base element 1 or in the overvoltage protection device 2 comprising the base element 1 and the overvoltage protection element 10. Furthermore, it can be seen that the protection element receptacle 9 of the overvoltage protection element 10 is multi-pole, in this case three-pole, in the base element 1. Two poles of the protection element receptacle 9 are used to transmit the signal transmitted via the two-pole first receptacle 5 and second receptacle 7 to the overvoltage protection element 10, while the other poles are used to transmit the potential carried by the support rail 4 to the overvoltage protection element 10. In the exemplary embodiment shown, the first receptacle 5 and the second receptacle 7 have a first separation width, which in the particular embodiment shown is 7 mm. The protection element receptacle 9 in the base element 1 has a second separation width, different from the first separation width. In the present case, the separation width of the protection element receptacle 9 is 5.15 mm.

[0040] exist Figures 2 to 4 The overvoltage protection device 2 shown in FIG. is distinguished by the fact that multiple basic elements 1 are arranged aligned side by side along the extension direction of the support rail 4. The multiple basic elements 1 are thus arranged parallel to one another on the support rail 4. Consequently, the first receptacles 5 of the multiple basic elements 1 and the multiple second receptacles 7 of the multiple basic elements 1 are also arranged side by side. These side-by-side first receptacles 5 and side-by-side second receptacles 7 are provided with integral adapter connector parts 17a, 17b that can be inserted integrally into the side-by-side first receptacles 5 and / or side-by-side second receptacles 7. The integral adapter connector parts 17a, 17b can therefore be handled as a single unit and do not consist of multiple loose, unconnected parts, although they do have multiple components, such as electrical contact elements held in the housings of the adapter connector parts 17a, 17b. This modular combination of a plurality of basic and individual base elements 1 with respectively associated overvoltage protection elements 10 makes it possible to very easily connect a large number of multi-pole connector parts 16a, 16b by means of corresponding adapter connector parts 17a, 17b.
