Definitions

  • the invention relates to an electrical terminal block with a terminal housing, with at least two conductor connection elements arranged therein and with two current bars.
  • the current bars each have a connection section, a first resilient contact section and a second resilient contact section.
  • the connection sections are each associated with a conductor connection element, the first contact sections together forming a first contact area and the second contact sections together forming a second contact area for receiving and contacting the plug of a test plug or a disconnect plug.
  • the first contact sections make contact when no plug is plugged in, so that the two conductor connection elements are electrically connected to one another via the two current bars, and the second contact sections are spaced apart from one another when no plug is plugged in.
  • the second contact area of the current bars is arranged in front of the first contact area of the current bars in the plug-in direction of the plug.
  • the two current bars each consist of two individual metal strips that are electrically connected to one another.
  • the two connection sections are each formed on a first metal strip and the contact sections are each formed together by a second metal strip.
  • the first metal strips have a stepped area with at least two steps at their end remote from the connection section, and the two second metal strips are fastened to two opposite steps of the stepped area of the first metal strips.
  • At least one first step and one second step are provided on the step-shaped area, and the first step is arranged behind the second step in the plug-in direction of the plug.
  • the invention also relates to a terminal block consisting of at least two terminal blocks arranged next to one another.
  • Electrical terminal blocks have been known for decades and are used by the millions when wiring electrical systems and devices.
  • the terminals are usually snapped onto mounting rails, which in turn are often arranged in large numbers in a control cabinet.
  • Feed-through terminal blocks with disconnection options are the standard in switching, measurement and control technology.
  • the possibility of separating realized in feed-through terminals of this type by forming a separating point in the current bar makes it possible to use different plugs with different functions into the terminal housing of the terminal block, which then contact the current bar at the point of separation.
  • test plugs can also be used as plugs, which can have special components and enable checking of the correct functioning of the circuit connected to the terminal block.
  • Terminal blocks with isolating points are used in particular to connect current transformers.
  • An important feature is that a connected current transformer is short-circuited when the secondary circuit is disconnected from the load.
  • Electrical terminal blocks which are generally disk-shaped, are often plugged together with several other electrical terminal blocks to form a terminal block and snapped onto a mounting rail or mounted in a wall cutout, for example a control cabinet.
  • the individual test plugs the width of which usually corresponds to the width of the terminal blocks, are connected to form a test plug block and placed together on a corresponding terminal block.
  • the requirement here is that the number of terminal blocks connected to one another and the number of test plugs combined to form a test plug block can be freely selected.
  • the test plugs combined into a test plug block should be actuated together as simply as possible, i. H. can be plugged together on the terminal block.
  • the electrically conductive connection in certain terminal blocks in a terminal block block is often to be interrupted first before the connection to the remaining terminal blocks is severed. It is known from the prior art that the switching operations of the time-staggered disconnection of the electrical connection are implemented by different plugs.
  • the DE 10 2012 017 429 A1 shows, for example, a test plug block in which the individual test plugs of the test plug block have contact plugs of different lengths.
  • the longer contact plugs of individual test plugs first enter the corresponding openings in the terminal housing of the terminal blocks and contact the first, leading contact area of the two current bars in the direction in which the test plug is plugged in. If the test plug block is pushed further onto the terminal block, the longer contact plugs dip into the second contact area, which opens this contact area so that the electrically conductive connection between the two current bars - and thus also between the two conductor connection elements connected to the current bars - is interrupted becomes.
  • the shorter contact plugs first make contact with the leading contact area in the terminal blocks before the shorter contact plugs also open the second contact area and the current flow of these terminal blocks is interrupted and possibly diverted via the test plugs .
  • An electrical terminal block as described above with a terminal housing, two conductor connection elements arranged therein and two current bars is from DE 10 2015 114 186 A1 known.
  • the two current bars each have a connection section and two resilient contact sections, each of which forms a contact area for receiving and contacting the plug of a test plug or a disconnect plug, the two contact sections being arranged one behind the other in the plug-in direction of the plug.
  • the two current bars each consist of two individual metal strips which are electrically connected to one another, in particular welded, soldered or riveted to one another.
  • test plug blocks or terminal block blocks known from the prior art is that for different switching operations plugs of different lengths must also be used. This makes it difficult to construct a test plug block suitable for the desired purpose, since there are countless ways of arranging the individual plugs.
  • first metal strips have a stepped area with at least two steps at their end remote from the connection section and that the two second metal strips have at two opposite steps of the stepped area of the first metal strips are attached.
  • At least one first step and one second step are provided on the step-shaped area, and the first step is arranged behind the second step in the plug-in direction of the plug.
  • the step-shaped area consequently extends in the direction of the plug-in direction of the plug.
  • the contact sections are either deeper in the housing or closer to the housing wall or closer to the insertion point of the connector.
  • the first metal strips and the second metal strips overlap.
  • the first metal strips and the second metal strips overlap in the full length of the C-back of the second metal strips or the first metal strips even protrude over the second metal strips.
  • the second metal strips are attached to the last step, the maximum length of the current bar is reached. The minimum length of the current bars is achieved when the second metal strips are arranged at the first step of the stepped area of the first metal strips.
  • the terminal housing is preferably designed in such a way that the second metal strips can be attached to any step of the step-shaped area.
  • the terminal housing offers enough space that the second metal strips do not protrude from the terminal housing.
  • the current bars are shorter or longer overall.
  • the opposing contact sections are each fastened on the same steps, so that the contact sections are arranged mirror-symmetrically to one another overall.
  • the formation of the second contact area on the current bar ensures that an inserted plug of a test or isolating plug first contacts the second contact sections before the electrical contact of the two current bars is separated in the first contact area by the insertion of the plug.
  • an advantageous embodiment of the electrical terminal block provides that the second metal strips are in the form of C-shaped contact springs, which are fastened with their C-backs to a step of the stepped area of the first metal strips.
  • the two mutually facing contact sections of the two contact springs serve as a kind of insertion funnel for the plug of the test or isolating plug to be inserted, so that the risk of tilting is minimized and the plug is guided into the contact area at the same time. Due to the configuration and bending of the second metal strip to form contact springs with two legs, the contact force acting on an inserted plug by the contact springs can be easily adapted to the respective requirements.
  • the stepped areas of the first two metal strips are mirror-symmetrical and the remaining part first metal strips are configured congruently to each other. Due to the mirror-symmetrical arrangement of the stepped areas, they are arranged in an approximately V-shape with respect to one another. The distance between the opposite steps of the two connecting sections increases as the number of steps increases. The spacing between the first steps is less than the spacing between the second steps because the steps are further outwardly oriented by the step projections. Due to the stepped projections, a defined area is specified for the contact sections, to which the contact sections can be attached.
  • the first metal strips are slightly angled at the transition to the stepped area, so that the opposite steps of the stepped areas are all approximately the same distance from one another.
  • two spring elements are arranged in the terminal housing, each of which has a resilient contact section, that the contact sections of the two spring elements together form a further contact area for the plug, which in the plug-in direction of the plug is in front of the second contact area of the current bar is arranged, and that at least one of the spring elements has a receptacle for one leg of a jumper, one spring element being electrically conductively connected to a current bar via the plug when the plug of a test plug or a disconnect plug is plugged into the terminal block.
  • two leading spring elements are arranged in the terminal housing of the electrical terminal block, so that when the plug of a test or isolating plug is plugged in, it is first contacted by the contact sections of the spring elements before the plug hits the contact sections of the current bar and also makes contact with them. Before the plug of a test or isolating plug thus separates the contact between the contact sections of the two current bars, electrical contact is made between the plug and the additional spring elements. An electrically conductive connection is then established between a respective spring element and the associated current bar via the plug of a test or isolating plug inserted into the terminal block.
  • a further embodiment of the invention provides that a recess is formed in at least one of the spring elements as a receptacle for inserting a leg of a jumper.
  • the spring elements can be approximately S-shaped overall, with the connecting sections also being used to securely fix and hold the spring elements in the terminal housing.
  • the production of the spring elements can be further simplified if a recess is punched out of the corresponding spring element, in particular its connecting section, as a receptacle for inserting a leg of a plug-in bridge.
  • the spring elements can then be manufactured particularly easily as stamped and bent parts.
  • the terminal housing has at least one plug-in opening for inserting the leg of a plug-in bridge into the receptacle of a spring element, with the plug-in opening being accessible from a first side, the operator side.
  • terminal blocks or a terminal block consisting of a plurality of terminal blocks arranged next to one another are usually snapped onto a mounting rail which is fastened in a control cabinet.
  • such a terminal block can also be used directly in a corresponding opening in a cabinet wall.
  • the orientation of the terminal blocks is always the same, so that the terminal blocks are arranged with their operating side facing the cabinet opening or with the operating side protruding from the opening in a cabinet wall.
  • the plug-in opening is therefore accessible from the operating side for easier operation.
  • an opening for inserting the plug of a test plug or a disconnect plug into the contact areas is formed in the terminal housing, wherein the opening is accessible from a first side, the operator side.
  • a further embodiment of the invention provides that at least one of the first metal strips has a bridge recess and at least one corresponding bridge shaft formed in the terminal housing for receiving a leg of a stretching bridge.
  • the additional jumper shaft for accommodating the leg of a jumper can be arranged on the side of the housing. If the bridge recesses are provided on the two first metal strips, they can be offset from one another. Correspondingly, the bridge shafts can also be offset from one another in the terminal housing, so that no obstructions occur when two plug-in bridges are inserted. In the staggered arrangement, the jumpers can also be inserted into the center of the terminal housing without any problems.
  • the invention relates to a terminal block with at least two terminal blocks arranged next to one another, according to patent claim 10.
  • the terminal block according to the invention is characterized in that the terminal blocks are configured according to the invention.
  • the second metal strips of at least one terminal block are attached to a different step of the stepped region of the first metal strips than the second metal strips of the other terminal block.
  • the terminal block can be adapted to the desired purpose from the outset and the contact sections can be attached to the first metal strip in a specific position in the housing. Contacts that are arranged on the last step of the stepped area are contacted first when a test plug is inserted, since the contacts are arranged closer to the insertion opening of the plug in the terminal housing. Correspondingly, contacts of the contact sections are not contacted until later, when they are arranged on one of the first steps. The individual switching processes are consequently no longer solved by different plugs, but by the different arrangement of the contact sections within the terminal housing. The risk of incorrect contacting due to an incorrectly selected test plug is eliminated as the same test plug can be used for each terminal block or a test plug block with the same test plugs can be used for each terminal block.
  • an alternative embodiment of the terminal block provides that the second metal strips of the terminal blocks are each attached to the same step of the stepped area of the first metal strips. Identical terminal blocks are therefore arranged in the terminal block.
  • the contact sections are all arranged on the same level, so that a test plug block or different test plugs can still be used on the one hand if this meets the user's requirements.
  • identical switching operations are also possible with identical test plugs, since the test plugs contact the contact sections at the same time when they are inserted.
  • Fig. 1a shows an inventive electrical terminal 1.
  • the terminal 1 has a terminal housing 2 made of plastic. Inside the terminal housing 2, two conductor connection elements 3, 3' are arranged, which are screw terminals in the present case.
  • connection elements 3, 3' can also be used as conductor connection elements 3, 3'.
  • the current bars 4, 4' are each designed in two parts, with a connection section 5, 5' for connecting the current bars 4, 4' to the conductor connection elements 3, 3' having a screw terminal.
  • a first contact section 6, 6' and a second contact section 7, 7' are formed on the current bars.
  • the first contact section has a first contact area 8 and the second contact section 7, 7' has a second contact area 9, which can be contacted by a plug 10, not shown here.
  • connection sections are formed on a first metal strip 11, 11' and the contact sections 6, 6', 7, 7' on a second metal strip 12, 12'.
  • the first contact sections 6, 6′ of the two current bars 4, 4′ are formed and arranged opposite one another on the second metal strips 12, 12′ that together they form the first contact area 8 for the plug 10 of a test or isolating plug, not shown here.
  • the first contact sections 6, 6' touch so that they are electrically connected to one another when no plug 10 is plugged into the terminal block 1.
  • the second contact sections 7, 7' are also oriented opposite one another and together form the second contact area 9.
  • the second contact sections 7, 7' do not touch.
  • the end of the first metal strips facing away from the contact sections 6, 6′, 7, 7′ is connected to the connection section 5, 5′ with the screw terminals.
  • the first metal strips 11, 11' have a stepped area 14, 14'.
  • three stages are provided. From the Fig. 1a , 1b and 1c It can be seen that the second metal strips 12, 12', which are designed in the form of a contact spring 16, can be arranged at different stages 14 and can therefore be located at different positions in the terminal housing 2.
  • the contact sections 6, 6', 7, 7' formed on the second metal strips 12, 12' can thus be moved deeper in the terminal housing 2 or closer in the direction of the end face of the terminal housing 2, in particular in the insertion direction E of a plug 10 (not shown here).
  • the steps are arranged one behind the other in the insertion direction E, with a first step 17 being arranged behind a second step 18 and the second step 18 being arranged behind a third step 19 .
  • two spring elements 20, 20' are arranged in the terminal housing.
  • the spring elements 20, 20 ' are in the basic state of the terminal block 1 according to 1 , ie when the plug 10 is not plugged in, it is not electrically conductively connected to the current bars 4, 4'.
  • the two spring elements 20, 20' each have a resilient contact section 21, 21', with the spring elements 20, 20' being arranged mirror-symmetrically to one another in such a way that the contact sections 21, 21' have a further contact area 22 for a plug 10 of a test plug or a form the disconnect plug.
  • the contact sections 21, 21' can be at a distance from one another, so that they do not make contact. In principle, however, the contact sections 21, 21' can also be designed and be arranged so that the contact portions 21, 21 'contact when no plug 10 is inserted.
  • the spring elements 20, 20' are used to create a cross link between two terminal blocks 1 in a simple manner.
  • a recess is formed in at least one of the two spring elements 20, 20' as a receptacle 23 for one leg of a jumper.
