Background

An electronic housing of an electronic device, which may be, for example, a measuring, control and regulation, interface module, power supply or overvoltage protection device, serves to receive and protect electrical and electronic components of the electronic device. Furthermore, the electronics housing serves to accommodate electrical terminals for connecting the conductors to the electronics housing or to electrical and electronic components arranged in the electronics housing, wherein the individual components are usually mounted on a circuit board, at which the conductors are connected by means of the terminals. In particular, when the electronic housing is designed to be fastened to a support rail, the electrical connection terminals are usually arranged at the upper corners of the electronic housing facing away from the support rail, specifically, recesses are formed in the upper corners of the electronic housing, in which the connection terminals are arranged or mounted, so that the conductor connections of the connection terminals can be used for connecting the conductors. In this way, when a plurality of electronic housings or electronic devices are mounted adjacent to one another on the support rail, the connection of the conductors on the connecting terminals is simplified,

in the case of electrical connection terminals, screw terminals or spring terminals in the form of tension spring terminals or clip spring terminals are used in particular as conductor connections. The clamping principle of the tension spring terminal is similar to the bolt technology. This is done in the tension spring terminal by the clamping foot of the tension spring having a receptacle, when the traction sleeve pulls the conductor against the conductive beam in the screw terminal by actuating the adjusting screw. In contrast, the resilient clamping feet in the clamping foot spring terminal urge the conductor against the conductor beam.

To actuate the tension spring terminal, an actuating tool, for example a screwdriver, is required, which can be inserted into the actuating opening in order to open the terminal. The top of the screwdriver thereby tensions the tension spring, thereby opening the clamping point. The conductor to be connected can thus be introduced through the receptacle in the clamping foot, and can thus be clamped, after the actuating tool has been pulled out, by the receptacle of the clamping foot along a conductor rail connected to the tension spring.

In contrast, the clip spring terminal has the advantage that a rigid conductor stripped of insulation or a flexible conductor with a connecting sleeve can be connected directly to the terminal without tools by inserting the conductor into the clamping region between the end of the clip leg and the conductive beam. Such terminals are therefore referred to as in-line terminals or push-on terminals (see brochure "Reihenklemmen CLIPLINE 12011" from Phoenix Contact GmbH & co. kg, page 17).

In order to provide different connection possibilities for the user, functionally identical electronic devices are provided with substantially identical housings having different electrical connection terminals. Since the connection terminals to which different conductor connections are connected usually have different terminal housings, the individual electronic housings must be designed at least partially differently in order to be able to receive and contact different electrical connection terminals. This leads to the need for a plurality of variants of electronic devices or electronic housings for functionally identical electronic devices, such as homogeneous power supplies or interface modules, which leads to an increase in documentation and in particular to an increase in inventory management.

SUMMERY OF THE UTILITY MODEL

An object of the present invention is to provide an electronic housing, which can avoid the aforesaid disadvantages. Wherein the shell variables should be reduced as much as possible when providing the customer with connection variables.

This object is achieved in the electronic housing described at the outset by the features of the invention, namely that a second conductor connection and a second conductor rail are arranged in the terminal housing of the connecting terminal, wherein the first conductor connection is designed as a screw connection and the second conductor connection is designed as a spring-loaded connection. Furthermore, a second conductor feedthrough is formed in the terminal housing of the connecting terminal on the side opposite the first conductor feedthrough, so that a conductor introduced through the second conductor feedthrough can be connected to the second conductor rail in an electrically conductive manner by means of a second conductor connection. The connection terminal and the electronics housing are designed in such a way that the connection terminal can be placed in a first position in a recess of the electronics housing or in a second position rotated by 180 °, wherein the conductor to be connected can be introduced into the first conductor feedthrough in the first position of the connection terminal and into the second conductor feedthrough in the second position of the connection terminal.

According to the utility model discloses an electronic housing thereby has electric binding post, it is a "combination terminal", has the conductor connecting piece that is used for connecting two kinds of differences of conductor. If the electrical connection terminals are arranged at corresponding positions in the recess of the electronics housing, the conductors can be connected to the connection terminals by means of a screw connection or by means of a spring-clamping connection. Even if the electrical connection terminal has two conductor connectors, one of the two conductor connectors can always be connected via the respective conductor leadthrough when the connection terminal is installed in the electronics housing. The electrical terminals are thus arranged in corresponding recesses in the electronics housing, for example during the assembly of the electronics housing, so that the provision of an electronics housing with a screw connection or an electronics housing with a spring-loaded connection is achieved.

In an advantageous embodiment of the electronic housing according to the invention, a cover is formed in the area of the recess of the connecting terminal of the electronic housing, so that the connecting terminal can be removed from the electronic housing or can be inserted into the electronic housing when the cover is opened. It is thereby achieved that the user can change the orientation of the electrical connection terminal in the electronics housing even after the electronics housing has been installed, so that the conductor connection for connecting the conductors can be replaced. The electronics housing thus has a swivel plug serving as a connection terminal with two different connection ports or connection modes.

If the terminal is in the factory state of the electronic housing, for example in the first position of the electronic housing, in this state the first conductor lead openings in the terminal housing can be connected by means of the recesses in the electronic housing, so that the conductors can be connected by means of a spring-clamping connection. The user can also open the cover on the electronics housing, remove the electrical terminals, rotate them 180 ° and place them in a second rotated position in the electronics housing. The second conductor lead-through hole in the terminal housing can be connected with the conductor by means of a spring-clamped connection through a recess in the electronics housing. The electrical connection terminal thus has two different connection openings in two opposite directions, wherein one or the other connection opening can be used to connect an electrical conductor from the outside, depending on which of the two possible positions of the electronic housing the connection terminal is arranged in.

According to a preferred embodiment of the present invention, the protector plate is connected to the electronic housing by a hinge in one piece, so that the protector plate is not lost. The hinge is preferably configured as a film hinge, so that the hinge is only pivoted from its first closed position into its second open position. In order to make the cover as simple as possible to use, the cover and the hinge are preferably arranged on the upper side of the electronics housing. If the hinge is in its first closed position, it is preferably locked with the electronics enclosure, thereby ensuring that the bezel is in the closed position. Furthermore, a locking element can be formed between the cover and the electronics housing, which can only be opened by means of a special tool or a key, so that the opening of the cover can only be carried out by authorized persons.

In particular, there are different possibilities of forming the first conductor connection and the second conductor connection. In this case, even if the electrical terminal can have a plurality of first conductor connections and a plurality of second conductor connections, only one first conductor connection and one second conductor connection will be described in the following, so that the terminal is not a single-pole terminal but rather a multi-pole terminal. The individual first connection terminals and the individual second connection terminals are preferably each identically formed.

According to a first embodiment, the first conductor connection piece, which is designed as a screw connection, has an adjusting screw and a pulling sleeve, which can be actuated by means of the adjusting screw. Wherein a section of the first power rail is arranged in a receiving chamber of the traction sleeve, so that the position of the traction sleeve relative to the power rail can be changed by adjusting the adjusting screw. The conductor inserted into the receiving space of the pulling sleeve through the first conductor passage can be clamped by the pulling sleeve against a section of the first power rail, so that an electrically conductive connection is established between the conductor and the power rail. In this embodiment, the first conductor connection is a conventional screw connection, as is the principle that has been applied to electrical connection terminals for the last decades.

The second conductor connecting element, which is designed as a spring-clamped connection, has an annular tension spring according to one embodiment of the invention, wherein the tension spring and a section of the conductor rail form a tension spring terminal. The annular tension spring has a clamping leg and a supporting leg with a receptacle, which are approximately perpendicular to each other and are connected to each other by an arc-shaped back. The section of the conductor rail assigned to the tension spring passes through the receptacle in the clamping foot, so that a conductor inserted into the receptacle through the second conductor lead opening can be clamped against the conductor rail by the clamping foot or the lower edge of the receptacle. In this embodiment, the second conductor connection is a conventional tension spring, which has to be opened by means of a tool in order to be able to introduce the conductor to be connected into the receptacle of the clamping point via the clamping foot.

According to an alternative preferred embodiment of the invention, the second conductor connection part is a clamping foot spring having a clamping foot and a supporting foot, wherein the free end of the clamping foot or the clamping foot and the section of the conductor rail form a clamping point for the conductor passing through the second conductor pin opening. The clamping spring can be designed in a U-or V-shape, wherein the support leg can rest against a corresponding device wall or device projection in the terminal housing. The clamping spring can also have a nearly closed shape, wherein an angled fastening foot is also connected to the support foot. The fastening foot can have an opening through which a portion of the conductor rail extends, wherein the end of the angled fastening foot preferably rests on the conductor rail, so that the clamping foot spring is fastened to the conductor rail in a self-supporting manner.

If the second conductor connection piece is designed as a leg spring, the electrical connection terminal has a screw terminal and a leg spring terminal, so that the rigid conductor can be simply inserted into the leg spring terminal without the need for a handling tool. In order to be able to connect the flexible conductor to the leg spring terminal and to be able to remove the connected rigid or flexible conductor from the connection terminal if required, according to a further preferred embodiment of the invention, an actuating opening for actuating a tool or an actuating handle is formed in the terminal housing. The clamping point is opened by moving the clamping foot against the spring force of the clamping foot spring by means of an actuating tool inserted into the actuating opening, for example the head of a screwdriver, or by means of an actuating handle pushed toward the inside of the housing, so that the connected conductor is sufficiently soft to be removed from the clamping foot spring or the flexible conductor can be inserted into the clamping point.

It was already mentioned at the outset that in addition to the first conductor connection piece and the second conductor connection piece, a first conductor rail and a second conductor rail are arranged in the terminal housing of the terminal. It is basically possible to have two conductor tracks separated from one another, so that only one conductive connection is allocated in each case. The two conductor rails are preferably connected to one another, so that the two conductor rails together with the connecting section form a common metal part. The metal part can here be stamped and bent out of a flat metal workpiece only, so that the final shape is obtained. The two power rails are preferably designed in an axially symmetrical manner to one another, wherein the connecting means is located between the two power rails.

In order to be able to connect the conductors both electrically at the connection terminals or conductor rails and also to electronic components, for example circuit boards arranged in an electronic housing, the two conductor rails can have a respective contact section each and a common contact section together. In particular, one or more contact sections can be designed as connection pins or as elastic contact prongs which can be inserted into corresponding contact holes in the circuit board. Alternatively, the contact sections can also be designed as contact springs which, in the mounted state of the electrical connection terminal, are in contact with corresponding contact surfaces, for example with a section of a conductive beam arranged in the housing of the electronic component or with contact surfaces on the circuit board.

The advantage of the pluggable contact portion is clearly that the removal and insertion of the electrical connection terminals into the electronics housing can be carried out particularly easily. Furthermore, if the two conductive tracks are also arranged axisymmetrically to one another, the two conductive tracks preferably have the same contact section. In this way, two identical contact openings for the two conductive sections are formed in the electronic housing or in the circuit board arranged in the electronic housing, so that the two contact sections can be inserted into the two contact openings by means of the two contact sections, regardless of whether the electrical connection terminals are in their first or second position.

Detailed Description

Fig. 2 and 4 show a part of a preferred embodiment of an electronic housing 1 according to the invention, namely the upper right-hand part of the electronic housing 1 with electrical connection terminals 2, which are arranged in recesses 3 in the electronic housing 1. The left part of the electronics housing 1, which is not shown here, can be formed in substantially the same manner, as the right part of the electronics housing 1 shown in the figures, in particular also with corresponding electrical connection terminals 2. Furthermore, terminals of other configurations or no terminals may also be arranged in the left part of the electronics housing 1.

In contrast, fig. 1 shows two electronic devices 4 ', 4 ″ each having an electronic housing 1 ', 1 ″ and an electrical connection terminal 2 ', 2 ″ as are known from the prior art. The two electronic housings 1 ', 1 ″ each have a mounting foot 5, by means of which the electronic devices 4', 4 ″ can be fastened to the support rail 6. Corresponding mounting feet according to fig. 2 to 4 for fastening to the support rail 6 can also be provided on the electronic housing 1 according to the invention.

As can be seen from fig. 1, the connection terminals 2 ', 2 "are arranged at the upper corners of the electronics housing 1', 1" relative to the support rail 6. The connecting terminal 2' is designed as a clamping spring terminal and the connecting terminal 2 ″ is designed as a screw terminal. The conductor connection is thus formed as a clamping spring in the terminal 2' and as a screw connection in the terminal 2 ″. It can also be seen that the electronic device 4 also has different outer dimensions due to the different housing shapes of the connection terminals 2', 2 ". For two functionally identical electronic devices 4, both device types must therefore be provided, which leads both to increased costs for documentation and to increased inventory management.

In contrast, the electrical connection terminal 2 in the electronic housing 1 according to the invention shown in fig. 2 to 4 has both a screw connection and a spring-loaded connection. For this purpose, a first conductor connection 8 and a first conductor rail 9 are initially arranged in the terminal housing 7 of the connection terminal 2, wherein a first conductor connection opening 10 is formed in the terminal housing 7, through which the conductor to be connected is introduced and is electrically conductively connected to the first conductor rail 9 by means of the first conductor connection 8. The electrical connecting terminal 2 also has a second conductor connection 11 and a second conductor rail 12. The first conductor connection 8 is configured as a screw connection and the second conductor connection 11 is configured as a spring-loaded connection. A second conductor lead hole 13 is also formed in the terminal housing 7 on the side opposite to the first conductor lead hole 10, and a second conductor connecting piece 11 can be connected thereto through the second conductor lead hole.

As can be seen from a comparison of fig. 2 and 3, the electrical connection terminal 2 can be placed in a first position (fig. 2) or in a second position (fig. 3) rotated by 180 ° in the recess 3 of the electronics housing 1. In a first position of the connection terminal 2, the conductor to be connected can be inserted into the first conductor passage 10, and in a second position of the connection terminal 2, the second conductor passage 13 can be connected via the recess 3 of the electronics housing 1, so that the conductor can be connected to the second conductor connecting piece 11. Even in the case of an electronic housing 1 according to the invention with an electrical connection terminal 2, in which the connection terminal is formed in the form of a "combination terminal", i.e. two different conductor connections 8,11 are provided, depending on the installation position of the connection terminal 2 in the electronic housing 1, only the first conductor connection 8 or only the second conductor connection 11 can be used for the connection of the conductors. The respective further conductor connection 11,8 and the connection opening, to be precise the conductor feed-through openings 13,10 and the conductor connection 11,8, are then directed towards the interior of the electronic housing 1 and are thus not available for connection of the conductors at this location.

As can be seen in particular from fig. 4, the cover 14 is formed in the region of the recess 3 of the electronics housing 1, so that the terminal 2 can be simply removed from the electronics housing 1 or placed in the electronics housing 1 when the cover 14 is opened. The cover 14 is connected integrally to the electronic housing 1 by means of a hinge 15, so that the cover 14 is not lost in the open, upwardly pivoted position. In the closed state of the cover 14, the cover is locked to the electronic housing 1 by means of corresponding locking tabs or locking hooks, so that the connection terminals 2 in the electronic housing 1 are fixed in their position. In order to allow the cover plate 14 to be easily attached, the cover plate 14 and the hinge 15 are arranged on the upper side 16 of the electronic enclosure 1, so that the cover plate 14 is rotated upward to open, as shown in fig. 4.

In the exemplary embodiment shown in fig. 2 to 4, the first conductor connection 8, which is designed as a screw terminal, has an adjusting screw 17 and a pulling sleeve 18. Furthermore, a section 19 of the first power rail 9 is arranged in the receiving space 20 of the traction sleeve 18, so that the first power rail 9 with the section 19 extends through the receiving space 20 of the traction sleeve 18. If the pulling sleeve 18 is moved upward relative to the section 19 of the first power rail 19 by pulling the adjusting screw 17, the conductor inserted into the receiving space 20 of the pulling sleeve 18 through the first conductor feed-through opening 10 can be clamped by the pulling sleeve 18 relative to the section 19 of the first power rail 9.

A clamping leg spring 21 is arranged as the second conductor connection 11 in the terminal housing 7 of the connection terminal 2, wherein the clamping leg spring 21 has a clamping leg 22 and a support leg 23. The free end of the clamping foot 22 and a section 24 of the second conductor rail 12 form a clamping point 25 for a conductor inserted through the second conductor feedthrough 13. In addition to the clamping leg 22 and the supporting leg 23, the clamping leg spring 21 also has a fastening leg 26, which is connected to the supporting leg 23 and is thereby bent approximately at right angles. As can be seen in particular from fig. 2b and 3b, the fastening foot 26 has an opening through which the section 24 of the second conductor rail 12 extends. Since the fastening foot 26 is bent back on itself into an L-shape, the free end of the fastening foot 26 lies on the section 24 of the power rail 12, so that the clamping foot spring 21 is fastened to the power rail 12 via the end of the fastening foot 26 and the free end of the clamping foot 22.

In order to open the clamping point 25, so that both flexible conductors can be inserted into the clamping point 25 and connected conductors can be removed from the clamping point 25, an actuating opening 27 is formed in the terminal housing 7, in which an actuating handle 28 is arranged. If the actuating handle 28 is moved or pressed from the upper position shown in the figures into the terminal housing 7, the end 29 of the actuating handle 28 projecting into the terminal housing 7 moves the clamping foot 22 against the spring force of the clamping foot spring 21, so that the clamping point 25 is opened. The connected conductor can thus be simply removed from the clamping point 25.

In order to also be able to electrically conductively connect the conductors connected to the connecting terminals 2 to an electronic component, for example a circuit board 30, which is arranged in the electronic housing 2, the two conductor rails 9,12 each have a contact section 31,32, which is designed as a resilient contact hook. The contact sections 31,32 are formed here for insertion or press-fitting into corresponding contact holes 33,34 in a circuit board 30 arranged in the electronic housing 1. By virtue of the two conductor rails 9,12 being designed and arranged axially symmetrically to one another, the two contact sections 31,32 can be inserted into the contact holes 33,34 in the circuit board 30, whether the connecting terminal 2 is in its first position (fig. 2) or in its second position (fig. 3) rotated by 180 ° about a transverse axis. It is basically sufficient if the electrical connection to the inserted contact sections 31,32 is made only via the first front contact hole 33, since the conductors are also connected only to the respective conductor tracks 9, 12; in the arrangement according to fig. 2, the contact section 31 is connected to the conductor rail 9, and in the arrangement according to fig. 3, the contact section 32 is connected to the conductor rail 12.

In the exemplary embodiment shown, the two conductor rails 9,12 are connected to one another by a connecting region 35, so that the two conductor rails 9,12 and the connecting region 35 form a common metal part which can be produced simply from a flat metal strip by stamping and bending.
