Definitions
- the invention is based on an industrial connector with an electrical fuse holder according to the preamble of independent claim 1.
- An electrical fuse holder is to be understood as a holder device for electrical fuses.
- the electrical fuses can in particular be overcurrent protection devices, such as fuses, for example.
- Such connectors are required to transmit energy, especially electrical energy, signals and / or data to devices such as work machines, switch cabinets or similar devices, particularly in an industrial environment.
- a specialist is often required to locate the corresponding source of error in a control cabinet, for example.
- fault localization can take a lot of time due to the need for increasingly complex control cabinets.
- systems in the field of information technology could be intentionally overused for a short time in order to absorb or enable power peaks. It can therefore make sense to have an affected energy line replaced by less qualified personnel first in order to save and / or bridge time.
- the replaced, defective energy line can then be checked centrally by a specialist, for example, in order to exclude the energy line as a source of error or to eliminate a defect that has occurred.
- the object of the invention is to offer an industrial connector which makes the maintenance of a system, in particular an industrial system, simpler and more maintenance-friendly and thus in particular reduces the potential risk for less experienced maintenance personnel.
- the industrial connector according to the invention is composed of an upper housing section for receiving a conductor and a lower housing section, which can be detachably connected to it, for receiving at least one contact carrier.
- the contact carrier makes at least one contact.
- the contact is intended to establish a connection with a corresponding mating contact for the transmission of at least electrical energy and / or electrical signals / data.
- At least one fuse holder for receiving at least one electrical fuse is arranged inside the industrial connector.
- the upper housing section here means the section of the industrial connector which is able to accommodate conductors and lines.
- cables for the transmission of electrical energy are meant as conductors.
- other conductors can be used, for example for fluids.
- fuse holder in this context means a device for Including an electrical fuse for an electrically conductive connection with at least one electrical conductor meant.
- the fuse holder creates an electrical connection between the contact inserted in the contact carrier and a conductor inserted into the upper housing section through an inserted fuse.
- the current strength and / or the voltage of the electrical conductor attached to the fuse holder is then protected by an inserted fuse.
- So-called fuses are preferably used as fuses, which, if the current intensity is too high, burn through for a certain time and thereby protect subsequent components from damage.
- the fuse holder advantageously holds two fuses.
- the fuse holder preferably holds three fuses.
- several fuse holders can be used, the fuse holders holding any number of fuses. Three fuse holders are preferably used, each of which holds a fuse.
- the industrial connector can have means for fixing the inserted cable, for example a cable screw connection.
- the industrial connector is inter alia through a corresponding plug-in opening and in particular by a corresponding so-called "plug face" for plugging with a corresponding mating connector, e.g. B. for signal and / or energy transmission, provided.
- the industrial connector can also have a separate so-called “holder frame” and / or a similarly acting holding mechanism firmly integrated into the industrial connector, as well as several insulating bodies arranged therein in the form of so-called “connector modules”.
- the industrial connector can at least partially consist of metal and for high currents and / or voltages be designed, so z. B.
- the industrial connector can have at least one PE (“Protection Earth”) contact, for example in the form of a PE screw or a plug contact.
- PE Processing Earth
- the industrial connector has a carrier element which receives the fuse holder and wherein the carrier element is connected to one of the two housing sections.
- the carrier element is connected to the lower housing section.
- it can also be useful to make the carrier element connectable to the upper housing section.
- the fuse holder it is recommended to releasably connect the fuse holder to a carrier element.
- excellent accessibility to the contacts used in the contact carrier can be guaranteed during an assembly process of the industrial connector.
- a connection from the contacts to the fuse holder can be easily established. Because through this embodiment, a contact connected to a conductor can initially can be inserted into the contact carrier, the contact carrier can be introduced into the lower housing section and then the conductor can be connected to the fuse holder before it is detachably connected to the carrier element.
- Another embodiment provides for the carrier element to be detachably connected to the upper housing section or the lower housing section. This increases the ease of assembly and further simplifies maintenance.
- a fuse holder according to the invention can be firmly connected to a carrier element. Nevertheless, an assembly similar to the previous description is simplified, since first contacts can be inserted into the contact carrier in order to then connect conductors connected to the contacts to the fuse holder and then to fasten the fuse holder to a housing section.
- a corresponding industrial connector can be used in a variety of ways in this way, since it can be used as a regular industrial connector.
- the releasably connectable carrier element is omitted if there is no longer a need for an electrical fuse for the current-carrying conductors.
- a conceivable embodiment recommends connecting the carrier element and the fuse holder each with at least one corresponding connecting element.
- a positive connection between the fuse holder and the carrier element is particularly preferred.
- a standardized rail a so-called “top-hat rail”
- top-hat rail By using a top-hat rail, it is possible to use fuse holders that are usually used in control cabinets. Such a configuration enables a particularly high number of variants.
- Such a modularity can have an advantageous effect, especially if the requirements for the lines to be protected differ.
- the state of at least one inserted electrical fuse can be read through a viewing opening in the upper housing section and / or the lower housing section.
- a viewing window is designed to enable a visual inspection of the electrical fuse.
- the state of at least one electrical fuse that has been used is represented by at least one signal.
- the state of an electrical fuse used is preferably displayed by a light source.
- a light-emitting diode (LED) is particularly preferably designed as the lighting means.
- a light-emitting diode can advantageously be arranged on the fuse holder through a viewing window. Nevertheless, the state of the electrical fuse received by the fuse holder can be recognized from outside the industrial connector. In the event of a defect, the maintenance personnel deployed can recognize at first glance a cable with an industrial connector according to the invention that is to be replaced.
- the industrial connector can also have a locking mechanism, e.g. B. in the form of a locking bracket or two push buttons o. ⁇ .
- a locking mechanism e.g. B. in the form of a locking bracket or two push buttons o. ⁇ .
- the push buttons may have the advantage of simplified operation, since only the two push buttons have to be moved towards each other for locking, ie they can advantageously be pressed together by the user with one hand.
- the locking bracket may have the advantage that it automatically presses the industrial connector and the mating connector against one another in a sealing manner when locking, without the need for a special mechanism.
- a locking can also be automated, for example by means of a corresponding electromechanical device. In this way, for example, "pulling under load" can also be prevented.
- FIG. 1 shows an illustration of an industrial connector according to the invention
- FIG. 2 shows a perspective view of a partially disassembled industrial connector according to the invention
- FIG. 3 shows a perspective view of a fuse holder with a lower housing section and a carrier element arranged thereon;
- FIG. 4 shows a perspective view of a fuse holder and a carrier element arranged thereon with a lower housing section.
- FIG. 1 shows an industrial connector 1 according to the invention.
- the upper housing section 2 is provided with a cable attachment 12.
- the cable attachment 12 shown is a screwed cable connection through which a cable is passed screw the cap jammed and thus secure it against being pulled out.
- a sight glass 13 can be seen, which protects a viewing opening 10 against the ingress of foreign bodies.
- the upper housing section 2 is detachably connected to the lower housing section 3.
- a flat tool is required, for example a slotted screwdriver, in order to release a latch between the upper housing section 2 and the lower housing section 3.
- a simple, tool-free opening of the industrial connector 1 is to be prevented by this design.
- an industrial connector 1 is shown in a partially disassembled view. More precisely, in the embodiment shown, the upper housing section 2 has been detached from the lower housing section 3. As a result, the fuse holder 6 arranged on a carrier element 8 comes to light. Furthermore, electrical fuses 7 inserted in the fuse holder 6 can be seen. It goes without saying to a person skilled in the art that instead of the illustrated fuse holder 6 with Next, contact carriers 4 and 4 ′ inserted in the lower housing section 3 as well as contacts 5 located therein can be seen. The contacts 5 ‘used in the contact carrier 4‘ are arranged within the insulating, cylindrical extensions.
- a connecting element 9 is integrally formed on the carrier element 8.
- a connection element 9 is shown in the form of a flood rail, as a result of which a fuse holder 6 can be used as a known component from a switch cabinet.
- a standardized top hat rail can be attached to the carrier element 8, for example by means of a screw or rivet connection, as a connecting element.
- a stop 14 is provided in order to be able to lay electrical conductors cleanly past the fuse holder 6, a stop 14 is provided. This stop 14 simplifies the positioning of the fuse holder 6 on the carrier element 8, so that further lines can simply be laid past the fuse holder. This design can be particularly advantageous when using a PE conductor.
- the lower housing section 3 is detachably connected to the carrier element 8 in this example. However, a one-piece design is also conceivable.
- a lighting means 11 arranged on the fuse holder 6 is also shown.
- the lighting means 11 is positioned in such a way that, when the industrial plug connector 1 is assembled, the lighting means 11 can be recognized through the viewing opening 10 and the inspection glass 13 of the upper housing section 2.
- Latching elements 15 used can also be seen in this illustration. These latching elements 15 are brought into engagement with the lower housing section 3, so that the carrier element 8 and the fuse holder 6 attached to it are simply connected to the lower housing section 3.
