Definitions

  • the invention relates to a connecting terminal for electrical conductors, having a contact element substantially in the form of a U-profile, provided for the purpose of electrically contacting the conductor, having a substantially U-shaped clamping spring, in the form of a leaf spring, which keeps the conductor in electrical and mechanical connection with the contact element, and having an insulating housing which accommodates the contact element and the clamping spring, said housing having an insertion side, a mounting side, a top side, a bottom side, and at the insertion side at least one insertion opening for the conductor, said contact element having a first profile section possessing substantially a L-shape with a first and a second limb and with a plug-in opening which is aligned with respect to the insertion opening, and with a second, substantially flat profile section, whereby the clamping spring has a support limb being connected to the second profile section of the contact element, and a clamping limb which is configured to be positioned with its free end against a conductor inserted into the plug-in opening
  • EP 1 217 692 B1 shows a connecting terminal for electrical conductors, having a contact element provided for the purpose of carrying electrical power, a clamping spring, which keeps the conductor in electrical and mechanical connection with the contact element, whose material is different from the material of the contact element and which is in the form of a leaf spring, and an insulating housing, which accommodates the contact element and the clamping spring, having an insertion opening for the conductor, the contact element having a first profile section having a plug-in opening which is aligned with respect to the insertion opening and a second profile section which is bent back at an angle from the first profile section in the plug-in direction of the conductor, and the clamping spring being connected at one end to the first profile section of the contact element, and it being possible for the clamping spring to be positioned with the other end against the conductor to be connected to the terminal in order to press it against the second profile section, whereby the clamping spring extends, next to one end which is connected to the contact element on the front side (in the plug-in direction of
  • the object of the present invention is to provide an improved connecting terminal, which can be made very compact and where the clamping spring is protected against overstretching when releasing the conductor.
  • connection terminal with the features as pointed out in claim 1.
  • the clamping spring is accommodated within the U-profile of the contact element, and the U-shape of the clamping spring opens towards the mounting side of the housing, and an arrester bar extends from the inner wall of the mounting side into the open space between the support limb and the clamping limb of the clamping spring to serve as a dead stop for the bending movement of the clamping limb when releasing the conductor from the first limb.
  • an internal dead stop for safeguarding the clamping spring against overload or overstretching when pressed in the opening direction for releasing the conductor is achieved by the invention in a very simple and cost effective way, as according to the invention the dead stop is integrated into the housing wall.
  • Housings for a connection terminal according to the invention are most frequently made by injection moulding of insulating plastic material, and so the dead stop for overload protection of the clamping spring can advantageously be manufactured in the same injection moulding process as the housing parts.
  • the arrester bar is integrally shaped to the inner wall of the mounting side and extends substantially parallel to the bottom side, heading towards the insertion side. This allows for a space-saving arrangement of the clamping element within the housing, nonetheless giving easy access for a conductor to be inserted, and so this solution is particularly useful for designing small and compact connecting terminals.
  • a supporting wall is integrally shaped to the inner wall of the mounting side or to the lower side of the arrester bar which faces the second profile section of the contact element, leaving a slot between said second profile section of the contact element and the supporting wall, the slot thickness being adapted to the thickness of the support limb of the clamping spring, whereby the support wall presses onto the support limb of the contact spring to support its fixation to the second profile section of the contact element.
  • the housing is composed of a base part and a cover part, which are held together by a snap action mechanism, whereby the cover part is forming the mounting side and the base part is forming the insertion side.
  • the support limb of the clamping spring is fixed to the second profile section by a latching mechanism comprising a latching recess in the second profile section and a latching tongue formed in the support limb of the clamping spring by slot-like recesses and resiliently projecting out of the plane of the support limb.
  • a conductor guiding tube is formed to the insertion side of the housing, the inner side of the conductor guiding tube establishing a guiding channel for the conductor, the channel being aligned with the insertion opening and the plug-in opening.
  • the plug-in opening is formed in the transition edge between the first and second limb of the first profile section.
  • a contact recess providing access for a tool to the clamping limb of the clamping spring for the purpose of pressing the clamping limb towards the support limb for releasing the conductor.
  • a housing recess aligned with the contact recess providing access for a tool to the clamping limb of the clamping spring.
  • the distribution unit 1 has a substructure 7 in form of a mounting plate. There are two locations with means for installing a top hat rail 32, also called a DIN hat rail, to the substructure 7. Instead of the top hat rail 32 shown any other kind of profiled rails allowed in the various technical standards that are applied in different countries throughout the world for electrical distribution boards may be applied.
  • the top hat rail serves for mounting electrical installation devices, such as miniature circuit breakers (MCM), residual current circuit breakers (RCCB), contactor devices, overvoltage protection devices or the like.
  • MCM miniature circuit breakers
  • RRCB residual current circuit breakers
  • contactor devices such as an MCB device 33 is mounted to the top hat rail 32.
  • the distribution unit 1 shown in figure 1 two such top hat rails can be installed in parallel and at a distance apart from each other, although only one of them, the one close to the topside edge 34 of the mounting plate 7 of distribution unit 1 is shown.
  • the distribution unit 1 is further comprising a terminal block arrangement, in particular for connecting protective earth conductors and neutral conductors (PE/N terminal).
  • the terminal block arrangement is located at the topside edge of the mounting plate 7.
  • the terminal block arrangement has a mounting strip 2 and connecting terminal modules 3, only one module 3 shown in exemplary mode in figure 1 , that can be fitted to the mounting strip 2 next to one another in a row.
  • the terminal block arrangement usually has a conductor rail and a number of connection elements for the purpose of connecting conductors to the conductor rail.
  • Each of the modules 3 has at least one of the connection elements.
  • the modules 3 have an insulating housing 4 and a conductor rail section (not shown here in figure 1 ) which is arranged within the housing 4.
  • the conductor rail sections are forming the conductor rail, and the terminal block arrangement has links for the purpose of electrically connecting the conductor rail sections of modules which are fitted next to one another on the mounting strip.
  • the distribution unit 1 has a first and a second support 5, 6 for the mounting strip 2 being disposed at a spacing from one another on the substructure 7. Located next to the first and second supports 5, 6, there are additional first and second supports 5', 6', situated a small distance below the first and second supports 5, 6. The height above the mounting plate 7 of the first and a second supports 5, 6 is larger than the height above the mounting plate 7 of the additional first and second supports 5', 6'. So the additional first and second supports 5', 6' allow for fixing the mounting strip 2 close to the mounting plate 7, and the first and second supports 5, 6 allow for mounting the mounting strip 2 at a certain distance above the mounting plate 7.
  • Figure 1 shows the situation where a first mounting strip 2' is fixed to the additional first and second supports 5', 6', a second mounting strip 2 is shown in a position before fixing to the supports, the arrows indicating the direction of insertion to the supports 5, 6.
  • the mounting strip 2 is being secured to the supports 5, 6, whereby for this purpose the mounting strip 2 has coupling parts 8, 9 being formed at its opposing narrow ends.
  • Each of the coupling parts 8, 9 have a latch that can be released by pressing it in direction towards the free end of the mounting strip 2 by a tool or by a finger. The latch biases into a retaining position.
  • the mounting strip 2 is formed as an elongated cube-shaped rod.
  • the rod has two rectangular broad long-edged plates 11, 12 which are connected by two rectangular narrow short-edged plates 13, 14.
  • the long edges of the broad long-edged plates 11, 12 and the narrow edges of the narrow short-edged plates 13, 14 define two narrow long-edged side sections 17, 18.
  • Each of the housings 4 and the mounting strip 2 have devices for the purpose of plugging the modules 3 to the mounting strip 2, transversely with respect to the longitudinal direction of the mounting strip 2.
  • Said devices on the side of the mounting strip 2 are formed as projecting bars 20, oriented transversely with respect to the longitudinal direction of the mounting strip 2, arranged in parallel to each other, formed to the outside of one of its rectangular broad long-edged plates 11, 12.
  • Said devices on the side of the insulating housing are formed as at least one slot 21 (see fig. 2 ) oriented transversely with respect to the longitudinal direction of the mounting strip 2 and adapted for positive locking of the bar 2 into the slot 21 when plugging the module housing 4 to the mounting strip 2.
  • Each housing 4 has a mounting wall 45 and at least one receiving slot 21 in the mounting side 45.
  • the mounting wall 45 has an insertion edge 42 and that the receiving slot 21 has an insertion opening 43 at the insertion edge 42, extending from the insertion edge 42 upwards towards a second edge 44 of the housing 4 located opposite the insertion edge 42.
  • the receiving slot 21 extends about half the way up from the insertion edge 42 to the second edge.
  • the insertion opening 43 is a little wider than the receiving slot 21, facilitating the pushing of the module housing 4 to the connection bars.
  • the mounting strip 2 has a number of connection bars 20 projecting from one of its two rectangular broad long-edged front plates 11 and oriented transversely with respect to the longitudinal direction of the mounting strip 2. So the receiving slot 21 and the connection bars 20 are forming the mutual connection devices.
  • the connection bar 20 has a T-shaped cross-section, with a first plate-like limb 40 arising from the broad long-edged front plate 11, and with a second plate-like limb 41 formed at the free end of and perpendicular to the first limb 40.
  • connection bars 20 are all oriented in parallel and transversely with respect to the longitudinal direction of the mounting strip 2. They are arranged by being spaced apart in equal distances, forming a kind of raster. In figure 1 one sees a raster of sixteen connection bars 20, in figure 2 and 3a one sees a detail with six resp. seven of these connection bars 20.
  • the housing 4 of the module 3 has four receiving slots 21, all of said receiving slots 21 being arranged in a mutually spaced manner, spaced apart in the same equal distances as the connection bars 20. So the raster of the receiving slots 21 in the module housing 4 fits to the raster of the connection bars 20 at the mounting strip 2. This design allows for an exact positioning of the module housings 4, in a rastered, grid-like spacing along the longitudinal extension of the mounting strip 2.
  • connection bar 20 and the receiving slot 21 are adapted for a gliding cooperation when the connection bar 20 is inserted into the receiving slot 21 at the insertion opening 43.
  • Figures 3a and 3b show an embodiment where there is an alternative or additional means for fixing the module housing 4 to the mounting strip 2.
  • a resilient fixation arm 52 biases into a retaining position.
  • the resilient fixation arm is formed in the mounting wall 45 of the module housing 4 by slot-like recesses 53, 54, 55.
  • the fixation arm has a latching member 56here in the form of a latching nose, protruding out of the mounting wall 45.
  • recesses 57 formed, one of these is indicated in figure 4 .
  • each of the recesses 57 is located between two neighbouring connection bars 21, as also each resilient fixation arm 52 is located between two neighbouring insertion slots 21. It is not required to have as many resilient fixation arms as recesses. It may be sufficient for small housings to have as little as one resilient fixation are. In the embodiment of figure 3a there are only two resilient fixation arms, one to the left, one to the right, none in the centre. Each resilient fixation arm 52 is adapted for a resiliently latching engagement with a corresponding recess 57.
  • the free end of the resilient fixation arm 52 has a pushing member 58 at its end for pushing the end portion of the resilient fixation arm 52 towards the inside of the housing 4.
  • the latching member 56 can be released by pushing on the pushing member 58 and so pressing the fixation arm 52 towards the inside of the housing 4 for releasing the latching engagement.
  • the pushing member 58 exceeds the upper surface of the mounting strip 2 when the module is fixed to the mounting strip. So the pushing member 58 is accessible for a manual pushing operation, by finger or by a tool, even when the housing 4 is fixed to the mounting strip. So it is possible to release an individual housing out of a combination of housings arranged in a row and fixed to a mounting strip, even from within the combination.
