Description

[0001] Power supply module and modular contact protection system

[0002] The invention relates to a power supply module and a modular contact protection system with a power supply module.

[0003] Busbars are installed in control cabinets, for example, to conduct or supply electrical current. To prevent accidental contact with conductive busbars, contact protection systems are typically used. These include covering the busbars, for example.

[0004] The current carried by the busbars must be supplied to or fed into the busbars.

[0005] Adapters for power supply are known from the prior art. These adapters are arranged on the cover of the contact protection device and electrically contact the busbar for power supply. A corresponding adapter is known, for example, from EP 0270 996 A2. With these known solutions, firstly, the entire cover cannot be installed, as the adapter supplying the power requires space on the cover. Secondly, the overall height of the contact protection system increases by at least the height of the adapter.

[0006] Another type of power supply is known from EP 3 926 774 A1. In this case, contact pins are inserted into the contact protection on the rear side, opposite the cover. The contact pins are inserted through the rear side into contact holes in the busbar. For this, the busbars must be perforated or slotted, which incurs costs and effort. Furthermore, the additional elements require additional space. Likewise, no device drawing power from the busbar can be mounted at locations where the busbar is contacted by the contact pins, since the contact hole in the busbar is occupied by the contact pin.

[0007] EP 2 863496 B1 shows contact elements designed as terminals that contact busbars covered with contact protection modules at their outer periphery. Therefore, the object of the present invention is to overcome these disadvantages. This object is achieved by a power supply module according to claim 1 and a modular contact protection system according to claim 12. The respective subclaims relate to advantageous embodiments.

[0008] One aspect of the invention relates to a power feed module for a contact protection system for contact-safe contacting of busbars, wherein the power feed module has a base made of electrically insulating material with receptacles for busbars and a cover made of electrically insulating material covering the base, characterized in that the receptacles each have a contact element, wherein the contact elements are designed to electrically contact busbars inserted into the receptacles at their outer circumference, wherein the contact elements are each electrically connected to a terminal for an electrical conductor.

[0009] Because the receptacles have contact elements and the busbar is contacted at its outer periphery, the busbar does not need to be perforated or slotted. In particular, the busbar can be free of contact holes for power supply or the like. Furthermore, the fact that the receptacles are arranged in the base allows for a low overall height. The power supply module according to the invention is also simple and straightforward in design and construction, and easy and cost-effective to manufacture.

[0010] The contact element can, for example, be a part or section of the receptacle, in particular an electrically conductive part or section.

[0011] The receptacles can be designed as electrically conductive terminals. The contact elements can be designed as electrically conductive terminals. The terminals can be configured to engage around the outer circumference of busbars inserted into the receptacles. The terminals can be configured to electrically contact the outer circumference of busbars inserted into the receptacles by clamping.

[0012] In some embodiments, a receptacle can be a terminal and / or terminal-shaped. The terminal can be electrically conductive. The terminals can be configured to electrically contact busbars inserted into the receptacles at their outer periphery by clamping them.

[0013] The terminals can provide good and secure contact.

[0014] In some embodiments, it may be provided that the busbar is not mechanically held or fixed by the receptacle and / or the terminal, but only electrically contacted. Mechanically securing or fixing the busbar can be achieved in other ways, for example, by separate holding elements in the base and / or in or through a contact protection housing described below.

[0015] The contact elements can be electrically connected to the connection for an electrical conductor via an electrical conductor track. The terminals can be electrically connected to the connection for an electrical conductor via an electrical conductor track.

[0016] In some embodiments, the power feed module may comprise a base made of electrically insulating material with receptacles for busbars and a cover made of electrically insulating material covering the base, wherein the receptacles may be designed as electrically conductive terminals which may be configured to electrically contact busbars inserted into the receptacles at their outer periphery, wherein the terminals may each be electrically connected to a terminal for an electrical conductor.

[0017] The base and / or the cover can be an injection-molded part. The base can be a single piece. The cover can be a single piece. This allows the power supply module to be manufactured simply, cost-effectively, and easily.

[0018] In some embodiments, the power feed module can be configured such that at least three power busbars can be accommodated in the power feed module. The power feed module can be configured to feed a respective electrical current to at least three power busbars. In some embodiments, the respective fed-in electrical current can each have a different phase. Thus, for example, a three-phase alternating current can be transported or can be fed in by the power feed module by means of three power busbars. The connections can be arranged in a connection block on an outer side of the base. In some embodiments, the connections can each be electrically connected to one of the contact elements and / or one of the terminals via an electrical conductor track.

[0019] The base can have additional receptacles for busbars. It can be provided that each of the receptacles having respective contact elements is aligned with at least one of the additional receptacles in a busbar extension direction. In some embodiments, each of the receptacles designed as electrically conductive terminals can be aligned with at least one of the additional receptacles in a busbar extension direction. In some embodiments, the additional receptacles can be configured to mechanically hold and / or fix the busbars. In some other embodiments, however, the additional receptacles can also not mechanically hold and / or fix the busbars.

[0020] The power feed module can have passage channels for busbars extending between opposite end faces of the power feed module for passing busbars through the power feed module. This allows a busbar to extend completely and / or continuously through the power feed module.

[0021] Each of the receptacles containing the respective contact elements can be aligned with one of the through-channels by its through-section for a busbar. In some embodiments, for example, when a receptacle is designed as a terminal, each of the electrically conductive terminals can be aligned with one of the through-channels by its through-section for a busbar.

[0022] The cover can have a cover plate with a number of rows of regularly spaced through slots corresponding to the number of busbars to be contacted. The cover plate can, for example, be or have a flat cover plate. This allows the cover and / or the cover plate to be built over. For example, electrical devices can be mounted on or on the cover and / or the cover plate. It can be provided that electrical devices mounted on or on the cover and / or the cover plate can electrically contact one or more busbars, for example to draw power from the respective busbars.

[0023] The cover covering the base can have a mounting side with regularly spaced through slots. A single- or multi-pole busbar adapter can be mounted on the mounting side for electrically connecting busbars that can be accommodated in the receptacles.

[0024] The single- or multi-pole busbar adapter can pass through the cover's through-slots with at least one contact element for each busbar to be electrically contacted. The multi-pole busbar adapter can have a number of contact elements that can correspond to the number of busbars to be contacted. For example, the busbar adapter can have three or more contact elements. The contact element can contact a respective busbar if busbars are accommodated in the power feed-in module.

[0025] The busbar adapter can pass through the through-slots in the cover with hook-shaped retaining feet. The busbar adapter can have hook-shaped retaining feet. The hook-shaped retaining feet can be designed to engage behind busbars accommodated in the receptacles. In some embodiments, the retaining feet can fix and / or fasten the busbar adapter. Alternatively or additionally, in some embodiments, a retaining foot can electrically contact a busbar, so that current can be conducted to or from the busbar adapter through the retaining foot.

[0026] The terminal block can be fastened to the outside of the base via a detachable connection. The base preferably has fastening means for the detachable connection of the terminal block to the outside of the base on at least one of two opposite outer sides, particularly preferably on opposite long sides with respect to a busbar extension direction of the busbars of the base. The terminal block can be mounted on one of the opposite long sides of the base. This allows optional power supply from one of the two opposite long sides. For example, the power feed module can be mounted in a switch cabinet housing with horizontally extending receptacles or power busbars accommodated therein. For example, the power supply to the power feed module can then be effected perpendicular to the horizontal direction, i.e. from above or below.

[0027] At least the base and preferably the cover covering the base can be designed in several parts with respect to a busbar extension direction of the busbars. A plurality of base modules forming the base can be provided, which can be arranged in series with one another via complementary series connectors. Each of the base modules can have a number of receptacles corresponding to the number of current busbars to be accommodated. If the plurality of base modules are arranged in series with one another, the receptacles of the two base modules can be aligned in pairs and thus each form a continuous receptacle for busbars. Each base module can have some of the connections for an electrical conductor and a corresponding number of contact elements. For example, for a four-pole power feed-in module, two connections and correspondingly two contact elements connected via an electrical conductor can be arranged orbe included therein. When the two two-pole base modules are connected side by side, a four-pole base is provided for a four-pole power feed-in module.

[0028] The base can have at least one through-channel on at least one of its two opposite longitudinal sides with respect to a busbar extension direction of the busbars. Electrical conductor tracks can extend through this through-channel, with which the contact elements are each electrically connected to one of the terminals for an electrical conductor. The conductor tracks can be designed as flat bars, particularly for high currents. In one embodiment, the flat bars are designed identically to the busbars accommodated in the receptacles, at least with regard to their cross-section.

[0029] The conductor tracks can extend perpendicular to the longitudinal direction of the busbars from the base through the at least one through-channel into the terminal block. The conductor tracks can preferably be designed as flat bars. The conductor track preferably extends with one of its two opposite ends out of the base or a base module of the base, while the other end is received in the base or base module. The base or base module can, in the manner described above, have a through-channel extending perpendicular to the longitudinal direction of the busbars on opposite long sides. The conductors can optionally protrude from the base or base module via one of their two opposite ends through one through-channel or the other through-channel, and accordingly to one or the other of the two opposite long sides.The terminal block can be arranged on the side where the conductor track protrudes from the base or base module. The terminal block can be secured to the outside of the base via fastening means for detachably connecting the terminal block, in particular optionally on the side of the two opposite longitudinal sides where the conductor track protrudes from the base.

[0030] The power feed-in module, in particular the base of the power feed-in module, can have two base modules, each having four receptacles. One receptacle of one base module and one receptacle of the other base module can be aligned with each other. This creates four continuous receptacles for busbars. Each base module can have two contact elements in different receptacles. In this way, one contact element can be provided for each of the four continuous receptacles. Instead of four receptacles, any other number of receptacles can be provided, corresponding to the required number of poles of the busbar system, for example, three receptacles or five receptacles.

[0031] A further aspect of the invention relates to a modular contact protection system for contact-safe contacting of busbars, wherein the contact protection system comprises a power feed module according to the invention and at least one contact protection housing made of electrically insulating material with busbar receptacles for busbars. The contact protection housing comprises a housing base having the busbar receptacles and a housing cover with a mounting side that closes the busbar receptacles and can be optionally removed from the base.

[0032] The housing cover can have a flat cover plate with a number of rows of regularly spaced through slots corresponding to the number of busbars to be contacted. The housing cover can be built over with electrical devices, for example busbar adapters. Both the power feed module and the at least one contact protection housing can have a series connector on at least one of their two opposite end faces, via which the power feed module and the at least one contact protection housing can be detachably connected to one another. The contact protection system can have a series connector. A series connector or the series connector can be arranged between the power feed module and the contact protection housing. A series connector or the series connector can be detachably connected to the power feed module and to the contact protection housing.

[0033] The power feed module and the at least one contact protection housing can each have passage channels for busbars extending between their respective opposite end faces for guiding busbars through the power feed module and the at least one contact protection housing. Each passage channel of the power feed module can open into a passage channel of the contact protection housing.

[0034] At least one straight busbar can extend uninterruptedly through the interconnecting passage channels between the power feed module and the at least one contact protection housing.

[0056] In some embodiments, the power feed module 200 may include at least one bus bar 100 received in a receptacle 220. In some embodiments, the power feed module 200 may include at least three bus bars 100 received in respective receptacles 220.

[0057] The power feed module 200 and / or the base 210 can have one or more through-channels 260 for busbars 100. The through-channels 260 can extend in one or the busbar extension direction L. It can be provided that when a busbar 100 is accommodated in a receptacle 200, the busbar 100 can be arranged or accommodated in a corresponding through-channel 260.

[0058] The passage channel 260 can be arranged and / or extend such that a busbar 100 can be or can be passed through the power feed module 200. In some embodiments, one or the passage channel can extend between opposite end faces of the power feed module 200.

[0078] 200. The power feed module 200 may have one, several, or all features and / or advantages of a power feed module 200 described above and / or shown in Figures 1 to 5.

[0079] The contact protection system 1 can be a modular contact protection system 1. In particular, it can be provided that the contact protection system 1 can have more than one contact protection housing 2 and / or more than one power feed module 200. The contact protection system 1 can have at least one contact protection housing 2. For example, in the busbar extension direction L, a power feed module 200 can be arranged in front of or behind a contact protection housing 2. For example, in the busbar extension direction L, a power feed module 200 can be arranged between two contact protection housings 2.

[0080] The touch protection system 1 may include at least one busbar 100. In some embodiments, the touch protection system 1 may include at least three busbars 100.

The touch protection housing 2 and / or the housing base can have one or more spacer webs 11. The lower parts 10 can be connected to one another via one or more spacer webs 11. The lower parts 10 are connected to one another on their opposite longitudinal sides via the spacer web 11 at a distance d. In some embodiments, the housing base can be formed from one or more lower parts and / or one or more spacer webs 11. Alternatively, in some embodiments, the housing base can be formed in one piece.

[0083] The contact protection housing 2 has at least one busbar receptacle 3. It can be provided that the number of busbar receptacles 3 can correspond to the number of busbars 100 accommodated and / or receivable in the contact protection housing 2. The busbar receptacle 3 can be configured to accommodate one busbar 100. The contact protection housing 2 has a housing cover 4. The housing cover 4 can be detachably secured and / or fastened to the housing base and / or one or more lower parts 10. For example, the housing cover 4 can be hinged to the lower parts 10 and / or the housing base at an upper longitudinal edge of the housing cover 4, parallel to the direction L of extension of the busbar, and can be screwed to the lower part(s) 10 and / or the housing base with threaded screws 19 at a lower longitudinal edge opposite the upper longitudinal edge.Alternatively, in some embodiments, it may be provided that the housing cover 4 can be screwed, for example, both on the upper longitudinal edge and on the other lower longitudinal edge with threaded screws 19 to or with one or more sub-parts 10 and / or the housing base.

[0084] It can be provided that the busbar receptacle 3 can be arranged such that, when the busbar 100 is accommodated in the busbar receptacle 3, the busbar 100 can be or become contacted by the housing cover 4. It can be provided that the busbar receptacle 3 can be arranged such that, when the busbar 100 is accommodated in the busbar receptacle 3, the busbar 100 can be or become fixed in the busbar receptacle 3 by the housing cover 4.

[0085] The housing cover 4 can form or have a mounting side 5. The mounting side 5 can be flat. On the mounting side 5, an electrical device, for example a busbar adapter 7 with an adapter housing 8, can be or be placed variably on the contact protection 1 in the direction L of the busbar extension, and / or can be or be mounted variably on or on the housing cover 4.

[0086] The housing cover 4 can have through-slots 14. The through-slots 14 can be separated from one another by separating webs 15. The separating webs 15, which can separate adjacent through-slots 14 in the busbar extension direction L, can be thin, since they do not have to absorb any loads. In some embodiments, a fine grid and thus a highly variable arrangement of an electrical device, e.g., a busbar adapter 7, can be achieved on or at the housing cover 4 and / or the mounting side 5.

[0087] The through-slots 14 can enable contacting of the busbars 100 accommodated in the contact protection housing 2. It can be provided that the clear opening of the through-slots 14 only partially overlaps with the respectively assigned busbars 100. This can ensure that the electrical device, e.g. the busbar adapter 7, can be placed onto the housing cover 4 via L-shaped holding feet 9 (see e.g. Figure 8) initially along the upper stop of the through-slots 14.
