Description

The invention relates to a plug module with a mounting plate. The invention also relates to the use of part of a mounting plate.

Electrical devices usually have a plug for connection to a power network, into which a line is plugged for operation and which is in contact with an electrical supply network. The plug is usually attached in an opening of a housing of the device, which is an opening in the housing. The components arranged in the housing are thus contacted with the power supply system via the plug. If the device is to be protected in the event of a fault in the device itself, the line or the supply network, a fuse is usually used. This is designed, for example, as a glass tube fuse and electrically connected downstream of the switch. If an electrical overcurrent occurs, the fuse trips, so that a current flow through the housing is interrupted. As a result, excessive damage to components located in the housing is prevented. The disadvantage here is that after the malfunction has been rectified, the fuse must also be replaced, for which the housing must be opened. This leads to an increased workload.

It is therefore also known to use a circuit breaker in addition to or instead of the fuse. It is therefore possible to reset the circuit breaker manually so that it does not have to be replaced after it has tripped. To further increase comfort, the circuit breaker is usually arranged in a further opening in the housing, so that it can be operated from outside the housing. In most cases, the circuit breaker is also designed as an on / off switch. It is thus possible to operate the device from outside the housing and, in particular, to interrupt a current supply. Therefore, comfort is increased.

To simplify assembly, the switch and the plug are usually provided by means of a common plug module. The plug module has a mounting plate with two receptacles, which are designed as cutouts. The plug is fastened in one of the receptacles and the switch in the other. It is thus possible to adapt the plug and the switch to different applications and, in particular, different supply networks. All that is required is to replace the plug or switch.

Since the plug, regardless of the plug module, is always mounted in a corresponding receptacle, this usually has fastening elements. This is also used to attach it to the mounting plate. To fasten the switch, latching hooks are usually used, which are connected to the switch. This means that assembly can be carried out without additional tools. A comparatively large number of manufacturing steps are required to assemble the plug module, which is why assembly time and manufacturing costs are increased.

Out U.S. 5,197,789 A a computer case is known. This has a receptacle for a plug.

In DE 10 2009 022 075 A1 a device installation device is specified, which is used to connect an electrical device to a power grid and has a connection unit for electrically connecting the device installation device to the power grid. The device installation device has a housing and a mounting frame, the mounting frame having at least one feed-through opening that is open on two sides. The connection unit, the mounting frame and the housing are designed such that they each form a single module.

The invention is based on the object of specifying a particularly suitable connector module and a particularly suitable use of a part of a mounting plate, advantageously simplifying manufacture and expediently reducing assembly time and / or manufacturing costs.

With regard to the plug module, this object is achieved according to the invention by the features of claim 1 and with regard to the use by the features of claim 8. Advantageous further developments and refinements are the subject of the subclaims.

The plug module is used in particular to connect to a housing of a device. The device is expediently energized by means of the plug module, that is to say in particular any components arranged within the housing. The plug-in module is suitable for this, in particular provided and set up. It is preferably possible to attach the plug module to the housing. The plug module expediently has fastening means or receptacles for fastening means suitable for this purpose. For example, the connector module has one hole or several holes or the like for receiving screws, in particular countersunk screws. The holes are preferably designed at least partially in the shape of a funnel. Thus, there is an essentially flat surface in the assembled state provided, so injuries or damage are avoided.

The plug module has a mounting plate, the mounting plate in particular comprising the corresponding receptacles for the fastening means. The mounting plate itself has a base plate which is preferably designed to be essentially flat. In particular, the possible fastening means or the possible receptacle for the fastening means are introduced into the base plate, which simplifies the connection of the plug module to the housing. In particular, the base plate rests at least partially on the housing in the assembled state and is stabilized by means of it.

The base plate comprises a receptacle, which is designed in particular as a recess. The receptacle is preferably closed all round, that is to say is expediently designed as a hole. A plug is fastened, in particular detachable, within the receptacle. The plug is here initially a separate component from the mounting plate, which is fastened to the mounting plate, namely preferably the base plate, to produce the plug module. It is thus possible to provide the plug module for different sales markets, the plug only being replaced. The mounting plate itself can be used for all sales markets or at least a large part of them and for different devices. The plug preferably has a number of contacts, for example two contacts, each of which carries a different electrical potential during operation. Particularly preferably, the plug has a total of three such contacts, of which one phase, another corresponds to the neutral conductor and the remaining ground (protective conductor) or is at least assigned. In particular, the connector is designed as a male connector, so that a connection with a corresponding line is simplified. For example, the plug is a so-called low-temperature device plug.

A hollow cylindrical section is formed on the base plate, the cross section of which is in particular rectangular. The hollow cylindrical section is thus cuboid, for example. A switch is received by means of the hollow cylindrical section. In other words, the hollow cylindrical section is used to fasten the switch to the base plate. In particular, the switch is pushed into the hollow cylindrical section for assembly. At least the switch is at least partially surrounded by the hollow cylindrical section in the assembled state.

Due to the use of the hollow cylindrical section, the switch is connected to the base plate on the one hand, so that no further fastening means are required. In this case, the connection to the base plate takes place in particular by pushing the switch into the hollow cylindrical section, which is why assembly time is shortened and manufacture is simplified. On the other hand, the switch is protected from any damage by means of the hollow cylindrical section, which is why reliability is increased. In particular, the switch can also be designed in a comparatively filigree manner, which is why manufacturing costs are reduced.

The mounting plate is expediently designed in one piece, which is why manufacturing costs are reduced. The mounting plate is preferably made of a plastic, for example in a plastic injection molding process. A comparatively inexpensive production of the mounting plate is thus made possible. Since the hollow cylindrical section is designed to be comparatively large and robust, provision of a tool for this is simplified. Breaking off of individual areas of the mounting plates during demolding or other manufacturing steps is also essentially excluded, so that rejects are reduced. In particular, it is possible here to introduce different types of switches into the hollow-cylindrical section, so that a comparatively large number of different types of switches can be used. Thus, an area of application of the plug module is enlarged. As an alternative to this, the hollow cylindrical section is adapted to a specific type of switch. A comparatively secure connection of the switch to the mounting plate is thus possible.

For example, the course of the section is essentially parallel to the base plate. Here, for example, one side of the section is formed by means of the base plate itself. A space requirement is thus reduced. The course of the section perpendicular to the base plate is particularly preferred. Assembly of the switch is thus simplified.

The switch is, for example, an on / off switch. It is thus possible, by means of the plug module, to interrupt or set a current supply to the device on which it is mounted. Alternatively, the switch is a circuit breaker. The circuit breaker serves in particular to secure the device, in particular against an overload, such as an excessive electrical current or an excessive increase in the electrical current. Alternatively or in combination with this, the overload case comprises an excessive electrical voltage and / or an increase in the electrical voltage by more than a specific limit value. The circuit breaker preferably has a tripping device which, for example Is designed thermally and in particular comprises a bimetal. Alternatively, the release device is electrical, magnetic, hydraulic, or a combination thereof.

The switch is preferably suitable, in particular provided and set up, to carry a rated current that is between 0.1 A and 30 A or 50 A, for example. A nominal electrical voltage which is applied to the switch and which is carried in particular by means of the plug is suitably 110 V or 230 V and / or an electrical alternating current. The switch is preferably an on / off switch with integrated overcurrent protection. In other words, the switch performs both the function of the on / off switch and the function of the circuit breaker.

The switch is designed without a housing, at least in the area in which it is surrounded by the hollow cylindrical section. In this case, the hollow cylindrical section abuts the switch in a dust-tight manner. By means of the switch, in particular, a closure of the hollow cylindrical section is formed, so that the interior of the hollow cylindrical section is closed by means of the base which is formed by the switch. In summary, the section of the mounting plate serves at least partially as the housing of the switch and is used for the housing of the switch. Thus, initially no installation of a separate housing on the switch is required, which is why a work step is reduced. Rather, the section is connected to the switch as a housing.

In particular, the section engages corresponding fastening elements of the switch to which a housing of the switch is otherwise connected. A comparatively stable connection between the circuit breaker and the section is thus realized. For example, before mounting the switch on the mounting plate, the housing of the switch is removed and the switch is then inserted into the section. Particularly preferably, however, the switch is already manufactured without a housing and then inserted into the section. Thus, a number of required components is reduced, and therefore costs are reduced. This also reduces the number of work steps required, which is why assembly time is reduced and production is therefore simplified.

For example, it is possible here to operate the switch by means of corresponding electrical signals. The switch can preferably be actuated by means of an operating unit which is designed, for example, as a lever, in particular as a rocker arm, as a rocker or as a slide switch. Operation is thus simplified. Safety is also increased due to the possibility of manual operation. For example, in the intended state, the hollow cylindrical section is outside of the possible housing of the device. Manual actuation of the switch is thus essentially always possible. In the intended state, however, the hollow cylindrical section and the switch are particularly preferably located within the housing of any device on which the plug module is mounted. The switch is thus protected by the housing of the device.

The hollow cylindrical section is preferably closed by means of the base plate, which thus forms a cover of the section and is in particular arranged perpendicular to the course of the section. The base plate suitably has an opening which extends into the section. The opening is in particular smaller than the cross section of the section, so that there is a circumferential edge that serves as a projection. Any operating unit of the switch is arranged within the opening. It is thus possible to operate the switch from the side of the base plate opposite the section. Due to the reduced size of the opening compared to the section, there is a stop for the switch, so that excessive insertion of the switch into the section is prevented. For mounting, the switch is inserted into the section from the side of the section opposite the base plate. In an alternative to this, the opening is the same as the cross section of the section, so that the switch can be inserted from this side, that is, through the opening. This means that the switch can also be installed subsequently after the connector module has already been installed on the housing of the device.

For example, the base plate is flat on the side opposite the section, so that a space requirement is reduced. Particularly preferably, however, a flank is formed on the base plate on the side opposite the section and is arranged perpendicular to the base plate. For example, the flank is designed to be essentially rectangular. The flank prevents another object from approaching the base plate, so that there is always a minimum distance that corresponds to the flank. Because of the flank, it is thus prevented that the plug module or any device is approached excessively close to another object, such as a wall or the like, by means of which the operating unit would otherwise be actuated. Unintentional operation of the switch is thus prevented by means of the flank, which is why safety is increased.

For example, there is a further edge or several further edges, so that one Stability is increased. In particular, this prevents the plug module from tilting with respect to any further object. The operating unit is preferably arranged between the two flanks, which increases safety. The flanks are suitably essentially structurally identical to one another, which is why production is simplified.

If the control unit is not present, the flank is preferably still present, in particular if the base plate has the opening within which a component of the switch is arranged. For example, a signaling device is arranged in the opening, by means of which a switching state of the switch is signaled. This component of the switch is also protected by means of the edge. The use of the edge is therefore independent of the operating unit and also independent of any signaling device.

For example, the switch is fastened in the recess by means of gluing, which is why the expenditure of time is reduced. As an alternative to this, it is fastened by means of screws or clips, for example. However, the switch is particularly preferably in engagement with the section. For this purpose, the section expediently has a recess which is preferably located in a region of the section that is spaced from the base plate. The distance between this section and the base plate is preferably greater than 2/3 of the length of the section. In particular, the switch has a retaining lug which rests within the recess in the assembled state. In other words, the section and the switch are preferably locked together. The retaining lug itself is expediently designed to be elastically resilient or at least connected, for example molded, to an elastically resilient area of the switch. The retaining lug is expediently beveled so that it is easier to introduce the switch into the section, and the retaining lug preferably protrudes beyond the section. When the switch is inserted, the retaining lug is bent inwards until it is in the area of the recess. There, due to the elastic properties, the retaining lug is again moved outwards so that it lies in the recess. This prevents further movement of the switch with respect to the section, and the switch lies relatively securely within the section.

For assembly, it is only necessary to only introduce the switch into the section. No additional fastening means are required either, which is why manufacturing costs are reduced overall and assembly is simplified. The recess suitably has a plurality of recesses, expediently two recesses, which are located on opposite sides of the section. In this case, the switch expediently comprises a number of retaining lugs that corresponds to the number of recesses, with one retaining lug expediently in each case in each of the recesses in the assembled state. Because of the multiple retaining lugs / recesses, the connection of the switch to the section is improved, and detachment is prevented. Since the retaining lug is tied to the switch, it is only necessary to replace the switch if it is damaged. The mounting plate with the plug attached can continue to be used. In an alternative embodiment, the retaining lug is attached to the section or the base plate, and the switch has the recess.

For example, the inside of the section is flat, so that tilting or catching of the switch when it is inserted into the section is prevented. Particularly preferably, however, a web is arranged on the inside of the section which extends from the base plate along the course of the section. Here, the distance extends, for example, over the entire length of the section. Particularly preferably, however, the web extends only over a fraction of the length of the section and thus not over its entire length. In particular, the web always rests on the base plate and is thus spaced from any opening in the section.

For example, the end of the web opposite the base plate is of blunt design and is preferably used to limit the insertion of the switch into the section. In other words, a stop is formed by means of the web. In an alternative embodiment, the web is beveled at its end opposite the base plate, for example over its entire course or particularly preferably only over part of it. The bevel is used for centering and Positioning of the switch within the section, so assembly is simplified. In particular, the switch is held in a non-positive manner between the web and further components of the section in the assembled state by means of the web, so that a position of the switch with respect to the section is stabilized.

The mounting plate preferably comprises several such webs, for example all of them being blunt or all of them beveled. Particularly preferably, some of the webs are designed to be blunt and some of the webs are beveled. However, at least some of the webs or at least one of the webs serves to limit the insertion of the switch into the section. Another of the webs or the further webs serve in particular to position the switch within the section, that is to say in particular to center it.

In an alternative to this, the webs are or the web is spaced from the base plate, but nevertheless extends along the course of the section. In this case, the web is expediently located in the half of the section facing the base plate. This makes it easier to insert the plug.

For example, the sides of the section are designed to be essentially continuous. Particularly preferably, however, the side of the section facing the plug is cut out. Here, the recess on the side serves to accommodate a connection of the plug. For example, the recess is made essentially centrally in the side. Particularly preferably, however, only the edge of the side is cut out so that the cutout is open at the side. In the assembled state, the connection of the switch is expediently arranged within the recess. This connection is preferably electrically contacted with the plug, for example by means of a suitable line. Due to the recess, the space required for the line is reduced and damage to the line is essentially excluded. Assembly is also simplified.

For example, the plug is glued to the base plate. Alternatively, it is fastened using screws. The plug is particularly preferably latched to the base plate. In this case, the receptacle expediently has a step against which a collar of the plug rests in the assembled state. Because of the step, a flat surface of the connector and base plate assembly is realized. In particular, the collar is arranged on an operating side of the plug, and the plug is inserted into the receptacle with the side opposite the collar first. For example, individual latching hooks or the like are molded onto the base plate, by means of which the plug is attached. However, the individual latching elements, such as latching hooks, are particularly preferably arranged on the plug itself, so that production of the mounting plate is simplified. Resilient latching hooks and / or spring arms with latching elements attached thereto are preferably connected to the plug, the spring arms / resilient latching hooks being created, for example, by means of a sheet metal. When the plug is pushed into the receptacle, these are elastically deformed by means of the receptacle until further obstruction and deformation of this is prevented due to the complete insertion of the plug into the receptacles by means of the base plate. As a result, the latching hooks / latching elements spring outwards so that the plug cannot be removed from the receptacle.

The mounting plate is part of a plug module and has a base plate with a receptacle. The receptacle is used to attach a plug, which is received in particular by the receptacle in this case. In this case, the plug is suitably arranged at least partially within the receptacle. Furthermore, the mounting plate has a hollow cylindrical section which is arranged perpendicular to the base plate and is molded thereon. The section serves to accommodate a switch, and when the switch is received by the section, the switch is at least partially surrounded on the circumference by means of the section.

A hollow cylindrical section formed on a base plate of a mounting plate is used as the housing of a switch. In particular, the switch does not include a separate housing, but this is at least partially formed in particular by means of the hollow cylindrical section. In other words, the switch has no housing. For example, the switch only has a cover or the like, by means of which the section is closed in the assembled state. The mounting plate itself is part of a plug module, which in particular includes the switch. The mounting plate is expediently designed in one piece and is preferably made from a plastic in a plastic injection molding process. The base plate expediently additionally comprises a receptacle within which a plug is arranged. The plug is fastened inside the receptacle in the assembled state.

The invention also relates to a device with a housing and with a plug module which has a mounting plate. The mounting plate comprises a base plate with a receptacle into which a plug is attached. A hollow cylindrical section arranged perpendicular to the base plate is formed on the base plate, by means of which a switch is received and at least partially surrounded on the circumference. The plug module is preferably introduced into the housing of the device and thus in particular forms part of a side of the housing. The base plate is preferably located outside the housing and is attached to it, preferably by means of screws. A plurality of electrical / electronic components, which are expediently interconnected to form a circuit, are expediently arranged within the housing. The individual components are supplied with current in particular by means of the plug module, preferably by means of the plug. The current supply is expediently interruptible and thus adjustable by means of the switch.

The developments and advantages explained in connection with the plug module are to be transferred accordingly to the mounting plate / use as well as among each other and vice versa.

Corresponding parts are provided with the same reference symbols in all figures.

In 1 is schematically a device 2 with a housing 4th shown. The case 4th is made of a metal, and within it is a component 6th arranged, which comprises a plurality of electrical and / or electronic components. These are suitably interconnected to provide a specific function. The device also has 2 a connector module 8th on that in a side wall of the housing 4th is introduced. The connector module 8th has a plug 10 on, in one line 12 is plugged in when in operation. The administration 12 is electrically connected to a supply network, not shown, by means of which an alternating voltage of 230 V is provided.

The plug 10 assigns multiple pins 14th on, being one of the pins 14th electrically directly with the component 6th connected is. Another of the pins 14th is with a connector 16 a switch 18th connected, which is also part of the connector module 8th is. Another of the connectors 16 is electrically directly connected to the component 6th connected. A large part of the switch is located here 18th inside the case 4th , and only one control unit 20th of the switch 18th protrudes into an outside area around the housing 4th so that actuation by a user is possible. By pressing the switch 18th it is possible to have a current flow from the plug 10 to the component 6th to prevent or create. The desk 18th itself is an on / off switch with integrated overcurrent protection so that the switch 18th also acts as a circuit breaker.

In 2 is the perspective of the plug module 18th on the part that is outside the housing in the assembled state 4th located, and in 3 shown in an exploded view. The connector module 8th has a mounting plate 22nd which is made in one piece from a plastic in a plastic injection molding process. The mounting plate 22nd has an essentially flat base plate 24 one hole at each opposite end 26th for receiving countersunk screws. Hence the holes 26th designed essentially funnel-shaped. The connector module is attached using the countersunk screws 8th on the housing 4th .

The base plate 24 has a rectangular receptacle 28 on that one stage 30th includes, which is designed circumferentially. In the assembled state is in the recording 28 The plug 10 arranged, of a circumferential collar 32 having who at the stage 30th is applied. This is done by means of the 30th excessive insertion of the connector 10 in the recording 28 prevented. The plug 10 has a pot-shaped house 34 on that on the collar 32 is tied and by inclusion 28 reaches through. Inside the house 34 are three contacts 36 arranged, which are designed as a knife contact, and which through the pot bottom of the house 34 reach through and one of the pins 14th form. At the house 34 are as in 4th in a rear view of the connector module 8th shown, several snap arms 38 tied up to the locking of the connector 10 with the base plate 24 to serve. The snap arms 38 represent locking hooks and thus locking elements. Consequently, the connector is in the assembled state 10 with the base plate 24 latched.

At the base plate 24 is on the the outside of the case 4th opposite side a hollow cylindrical section 40 molded. The course of the section 40 is perpendicular to the base plate 24 , and the section 40 is by means of the base plate 24 locked. The base plate 24 shows a breakthrough in this area 42 on, which is thus in the section 40 reaches in. Here is the breakthrough 42 smaller than the cross section of the section 40 . When assembled is within the section 40 the desk 18th arranged, the control unit 20th within the breakthrough 42 is arranged. In other words, the section takes 40 the switch 18th and surrounds it on the circumference. Using the switch 18th is the section 40 on the breakthrough 42 opposite sides sealed, so that foreign particles can enter the section 40 is avoided.

The control unit 20th is designed as a rocker and is used to electrically isolate two of the connections 16 , in which a contact bridge 44 is spent accordingly. The desk 18th has a total of four such connections 16 so that by means of the switch 18th two separate circuits can be switched. Two of the connections each 16 is one of the contact bridges 44 too ordered.

The desk 18th itself is designed without a housing and only has a bottom 46 on, which is at least partially made of a plastic. Thus, the individual components of the switch are located 18th , so in particular the contact bridge 44 and a trip device comprising a bimetal trip such as a bimetal snap disk or a bimetal strip, free and the section 40 is called the housing of the switch 18th used. Thus, a weight is reduced. Also, there is initially no provision of a housing for the plug during assembly 18th required as well as appropriate assembly so that manufacturing steps can be saved.

By means of the soil 46 , also known as the base or lower part, is the section 40 on the breakthrough 42 opposite side closed. Through the ground 46 Two of the connections protrude here 16 . The remaining connections 16 are in another recess 48 the connector 10 facing side 50 of the section arranged. In other words it is the connector 10 facing side 50 of the section 40 to accommodate two of the connections 16 of the switch 18th left out. The further recess 48 is in one edge of the section 40 introduced so that it is partially open. This is a positioning of the connections 16 in the further recess 48 facilitated. For mounting the switch 18th this will be of the breakthrough 42 opposite side in the section 40 introduced. Here are the connections 16 into the further recess 48 introduced the limitation of a stop for the connections 16 forms. The one in the other recess 48 arranged connections 16 are by means of a line not shown with at least one of the pins 14th of the plug 10 electrically contacted. Because of the arrangement, only a comparatively short electrical line is required, which simplifies assembly.

On the floor 46 there is also a retaining lug on two opposite sides 52 integrally formed on that of the base plate 24 facing sides are beveled, and which are designed to protrude laterally and elastically deformable. The section 40 has a recess on two opposite sides 54 on, within each of which one of the retaining lugs in the assembled state 52 is arranged. When inserting the retaining lugs 52 in the section 40 these are bent inwards. Then when the holding noses 52 to the respective assigned recess 54 reach, they are in turn moved outwards due to the elastic deformation, so that they are in the respective recess 54 lie in. Thus there is another movement of the switch 18th regarding the section 40 prevented. By (manual) bending of the retaining lugs 52 inwards it is possible to use the switch 18th again from the section 40 to remove.

On the inside 56 of the section 40 are like in the 3 , 5 and 6th shown several webs 58 integrally formed, which is parallel to the course of the section 40 extend over a fraction of its length. Here is part of the webs 58 in contact with the base plate 24 and are on that of the base plate 42 opposite end designed blunt. This prevents excessive insertion of the switch 18th in the section 40 prevented, and the switch is in the assembled state 18th at each end. Thus, on the one hand, the soil is tight 46 at the section 40 realized. On the other hand, an unintentional operation of the operating unit is avoided in this way 20th prevented. In addition, the pressure on the holding lugs is relieved 54 acting forces. Part of the webs 58 is like that 3 and 5 shown on the the baseplate 24 beveled opposite side. These webs 58 are from the base plate 24 spaced and beveled on the opposite side. By means of these webs 58 the switch is centered 18th within the section 40 so that the switch 18th at the desired position within the section 40 is located. This puts a strain on the holding lugs 52 decreased. Furthermore, in this way, foreign particles can penetrate the individual components of the switch 18th how to the contact bridges 44 , avoided.

The mounting plate 24 has two flanks 60 on, which is perpendicular to the base plate 24 are arranged and formed on this. Here are the two flanks 60 on the the section 40 opposite side, and the breakthrough 42 is arranged between these, as in 7th shown. The bridges 60 are designed essentially rectangular and have a height that is greater than the maximum distance between the operating unit 20th from the base plate 24 is. By means of the flanks 60 ensures that no other object is closer to the base 24 than the control unit 20th survives over this. This is an unintentional actuation of the control unit 20th prevented due to the further object.

In 8th is an alternative embodiment of the mounting plate 22nd shown, which corresponds essentially to the previous embodiment. Only the two flanks 60 are omitted, so the mounting plate 22nd then when the plug 10 in the recording 28 is used, is essentially flat. Only through the breakthrough 42 outstanding control unit 20th stands over in this case.

In summary, is a mounting plate 22nd already in the housing of the switch 18th integrated. A housing is thus saved in the manufacture of the switch 18th . There is also an assembly step in the manufacture of the connector module 8th less available.
