Definitions

  • connection terminal which is arranged in the interior of the housing and connected to it and which produces the electrical connection of an internal circuit with electrical lines, ie the phase conductor, the neutral conductor and the earth conductor.
  • connection terminal has a housing, in the interior of which contacts are arranged, electrically insulated from one another.
  • One of the contacts is provided for connecting the protective conductor and is connected to a plug contact protruding from the housing.
  • the housing has a flat base, which is provided for placement on a flat surface and on which locking pins are formed, the plug-in contact protrudes laterally out of the housing.
  • the plug-in contact is initially angled twice, so that it has a section lying in the plane of the bottom of the housing, which is angled again at its free end in such a way that it projects over the bottom of the housing in approximately parallel alignment with the locking pins.
  • the plug-in contact has a slot which divides the contact into two legs which are parallel to one another and have teeth on their outer sides.
  • the distance between the legs from the respective outer edges is significantly larger than the diameter of a hole provided in the relevant part to be connected.
  • the legs are therefore difficult to insert into the hole, which is why a relatively large pressing force is required. This must be applied to the housing by the operator who wants to make the electrical connection.
  • connection or connecting terminal for electrical devices which also has a plug-in contact for the electrical connection of metallic carrier or housing parts.
  • the connecting terminal has a housing with a receiving chamber in which a spring terminal contact for connecting a protective conductor is arranged.
  • the spring terminal contact is connected to a plug designed as a tab, which protrudes from the housing on one flat side.
  • the plug extends straight from the housing without bending path.
  • Two tongues, which extend to the housing and are mutually bent away from the plug and form an acute angle with it, are punched out of the plug.
  • the plug is provided for insertion into a rectangular opening in a sheet metal used as a support, which is to be connected to the protective conductor.
  • the rectangular opening is matched to the dimensions of the connector so that it sticks in the opening.
  • the resilient tongues prevent it from slipping out of the opening. When inserting the plug into the undersize opening, the entire force required for insertion must be applied by pressing on the housing.
  • connection element for connecting electrical equipment which also has a plug-in contact as a grounding lug for the protective conductor connection.
  • the connecting element has a housing, from which an insulation displacement contact bent from a sheet metal is received.
  • the housing is arranged on a carrier and connected to it.
  • the carrier conductors must be electrically connected to a protective conductor.
  • an insulation displacement contact is provided, which also has a spring clamp contact formed by two tongues lying opposite one another on a bottom section. This is opposite a bottom-side opening provided in the housing, which is penetrated by the insertion lug of an earthing strap.
  • the insertion flag is inserted between the resilient tongues or tabs provided on the insulation displacement contact and is held by these and electrically connected.
  • a widened part adjoins the insertion flag with two cut-out locking tabs, which are slightly bent out of the plane of the earthing lug. They serve to lock the earthing lug into a slot-like opening in a carrier part, for example a housing base to be connected.
  • connection element too, the force required to insert the earthing lug into the slot-like opening must be applied to the housing by pressure.
  • the earthing lug protrudes above the housing base, so that, for example, if there is not enough space below the housing base, a complete insertion of the earthing lug into the opening is hardly possible.
  • connection element which can be assembled with little force without tools or other aids.
  • the connecting element when placed on its carrier, has no protrusions.
  • the metallic tab passes through the carrier when it is opened and lies flat against the back of the carrier so that no part protrudes from the carrier.
  • the connecting element is particularly suitable for connecting a protective conductor to a housing or a housing part of an electrical equipment, such as, for example. a lamp or the like.
  • the connection element can then be arranged in an interior space enclosed by the housing, for example on a rear wall of the equipment. Because of the flat contact of the tab on the housing section in question, the risk of injury compared to connecting terminals which have parts which are away from the housing wall is significantly reduced.
  • the hook portion of the tab which lies flat against the relevant wall portion in the assembled state, additionally secures the connecting element on the carrier part.
  • the hook section of the tab engages behind the wall section and thereby holds the connecting element on the carrier.
  • the connecting element can be mounted on a housing wall, which lies flat against the wall to which the equipment is attached.
  • the tab can be closed, slotted or provided with fingers at its neck section. It can also be flat or curved. It is essential that it has cutting edges that cut into the edge of the opening into which it is to be inserted. A bend or curvature of the neck section with a radius lying in the plane of the contact surface increases the rigidity of the tab against bending and allows a certain elasticity with respect to the opening.
  • the lug which is angled at its free end and thereby forms a hook section, is designed in terms of its width and rigidity in such a way that it forms a lever which facilitates the insertion of the lug into the opening provided in the carrier.
  • the hook section engaging behind the carrier is inserted through the hole provided in the carrier and, when the tab is pivoted, lies against the back of the latter.
  • the corresponding contact point defines the pivot axis about which the tab with the housing, which is connected to it, approaches the carrier is pivoted.
  • the distance between the neck section and the hook section is relatively small, while the lever as a whole is relatively long. This is formed by the tab and extended by the housing holding it.
  • connection element can be placed on the carrier without tools or other aids so that the tab with its neck portion is seated in the intended position in the opening. After hooking the hook section into the opening and pivoting the housing towards the carrier, the neck section pulls smoothly into the opening even if it has a clear excess. This ensures reliable electrical contact with the carrier formed, for example, by a sheet metal. Lacquer or oxide layers are easily penetrated. There are no additional fasteners such as screws, rivets or the like, as well as additional operations for contacting the carrier.
  • the tab can be produced inexpensively as a stamped / bent part, and the neck section and the hook section can each be essentially straight sections of a sheet metal tab. These are preferably angled at least 90 ° to one another. This forms an angle between the neck portion and the hook portion, which is at most 90 °. This preferably acute angle causes the tab to have its free end, i.e. with its hook section abuts the back of the carrier before the housing abuts the carrier with its contact surface. This ensures that the neck section is drawn into the opening under leverage and that the hook section rests with its tip on the carrier when the connecting element is installed.
  • the bracket itself is electrically connected by means of the tab, with the neck section into the opening is pressed in and is held there in the press fit.
  • the neck section then has edges which cut into the wall of the opening. This ensures safe electrical contact.
  • the tab may bend slightly when inserted into the opening, as a result of which an adaptation to supports with different wall thicknesses is possible.
  • the free end of the hook section is arranged at a distance from a plane which is defined by the contact surface of the housing . This distance is at most as large as the wall thickness of the carrier on which the connection element is to be arranged.
  • the hook section can be easily inserted into the opening if the width of the neck section is greater than the width of the hook section.
  • the length of the hook section should exceed half the width of the neck section.
  • the tab can be levered into circular holes so that no openings with special shapes are required.
  • a versatile design results when the tab is forked, so that the hook section and the neck section have a continuous, one-sided edge-open slot, which is suitable for forming an insulation displacement contact with a line.
  • the slot is preferably narrower in the area of the neck section than in the area of the hook section. This makes it possible to additionally and independently connect a conductor that is connected to other elements is. These can be, for example, parts or assemblies provided on the equipment, which are mounted in isolation but nevertheless have to be grounded. This also makes it possible to provide a non-electrically conductive support for the connection element and to bring about the desired contacting with a conductor inserted in the slot.
  • the insulation displacement connection between the conductor and the tab is created when the tab is inserted into the opening of the carrier part by the lever action of the tab which is supported on the carrier part by the hook section. This is possible without the aid of tools with low operating forces and can therefore be carried out manually. It does not matter whether the cable is stripped or not before insertion. In addition, a continuous line can be connected, which leads to another connection on both sides. If necessary, several lines can also be connected.
  • a particularly firm fit of the tab in the opening, which is secured against subsequent loosening, is achieved if the neck section has an abutment shoulder which lies essentially in the plane defined by the abutment surface. While the tab lies on one side with its contact shoulders on the carrier, it lies on the other side with the hook section.
  • a fastening means which allows the housing to be brought to the carrier in a pivoting movement is, for example, a latching body arranged on the contact surface of the housing. This allows, as long as it is not yet locked with corresponding openings provided in the carrier, the pivoting movement required for inserting the tab into the opening and does not require any kind of additional movement of the housing for fastening the same to the carrier.
  • other connecting devices such as screws, clamping brackets or the like can also be used as fastening means.
  • the housing is preferably formed by two housing parts which are positively connected to one another.
  • the positive connection can be a snap or snap connection, which leads to particularly simple assembly processes. However, other types of connections are also possible.
  • the connecting element can advantageously be used for connecting different parts which are at different potentials if the housing has at least one connecting means for connecting to further similar housings.
  • the connecting means preferably acts positively.
  • a connecting element can then be assembled from individual housings and can be used to connect the protective conductor, phase conductor, neutral conductor and, if necessary, other conductors to the electrical equipment in question.
  • the connecting means are, for example, grooves formed on the housings and corresponding ribs which can be inserted into the grooves and which are preferably provided with latching means.
  • the housings can thus be connected to one another in a simple manner by inserting the ribs into the corresponding grooves and shifting them to their latching position.
  • a particularly simple type of connection between the tab and the contact means arranged in the housing is obtained if the contact means has a spring-clamp contact which is designed in such a way that it holds and electrically contacts a connecting shaft provided on the contact body, when the contact body with its connecting shaft is inserted into the housing.
  • This spring-clamp contact can be made by simply cutting out corresponding contact tabs from the contact means. E.g. two opposing contact tabs can be between their clamp the free ends of the inserted shaft between them.
  • a connection element 1 shown in FIG. 1 has an insulating material housing 4 which is divided into two parts 2, 3 and which contains in its interior a contact 5 which will be explained in detail later (FIG. 5).
  • the insulating material housing 4 provided for mounting on a carrier 7, for example, shown in FIG. 2, starting from an approximately cuboid basic shape, has a U-shaped edge 8 facing the carrier 7, which defines a flat contact surface 9. This is arranged essentially parallel to a housing base 11 which springs back with respect to it.
  • a fastening projection 12 which extends away from the housing base 11 and is formed in one piece with the part 2 of the insulating material housing 4, is provided as the fastening means for holding the insulating material housing 4 on the carrier 7.
  • the latching projection 12 has two legs 13, 14 which extend at a distance parallel to one another and at right angles from the housing base 11 and which, at a short distance from a plane defined by the contact surface 9, each form an outwardly projecting shoulder 16, 17, from which starting Guide legs 18, 19 to run at an acute angle to each other, which are connected at the end via a web.
  • the locking projection is designed to be resilient. The legs 13, 14 can spring towards each other.
  • the parts 2, 3 of the insulating material housing 4 also have connection openings through which lines (not shown) can be connected to the contact 5 arranged in the interior of the insulating material housing 4.
  • the part 3, as can be seen from FIG. 1, is provided on its end face 21 with two spaced-apart cable entry openings 22, 23, to which spring-clamp contacts explained later in connection with the contact 5 are assigned.
  • both parts 2, 3 of the insulating material housing 4 define a slot 25 in which an insulation displacement contact is held so as to be isolated from the outside.
  • the part 2 of the insulating material housing 4 On its end face 26, which is opposite the end face 21 and arranged parallel to it, the part 2 of the insulating material housing 4 has an insertion opening 27, which can be seen, for example, from FIG 29 is.
  • the tab 28 is held firmly on the insulating material housing 4 and is designed to be rigid.
  • the tab 28 is a stamped sheet metal bent part which, following the insertion lug 29, as can be seen in FIG. 1, has a contact or neck section 31 which extends essentially at right angles to the housing base 11 and to the plane defined by the contact surface 9.
  • the neck portion 31 is a substantially flat, i.e. plate-shaped area of the tab 28 with a relatively large width, which is slightly smaller than the width of the insulating material housing 4. Approximately at the height of the plane defined by the contact surface 9, the width of the neck portion 31 increases in steps, whereby contact shoulders 32, 33 are formed on both sides are.
  • the neck section 31 with parallel flanks merges with a bending line 34 into a hook section 36, which includes an acute angle with the neck section, which is between 60 ° and just under 90 °. In the specific case it is 75 °.
  • the tab 28 tapers. This means that it no longer has parallel flanks but with flanks 38, 39 that converge at an acute angle is provided.
  • the neck section 31 is dimensioned in length such that the bending line 34, seen from the insulating material housing 4, lies beyond the plane defined by the contact surface 9. This means that the neck section 31 projects beyond the contact surface 9, but the hook section 36, starting from the bending line 34 lying at a distance from the plane of the contact surface 9, runs at an acute angle to the plane without, however, reaching the free end 41 thereof .
  • the distance between the free end 41 of the hook section and the plane defined by the contact surface 9 corresponds approximately to the wall thickness of the support 7 shown in FIG. 2.
  • the length of the hook section 36 in the tab 28 corresponds essentially to the width of the neck section 31.
  • the lower limit for the dimensioning of the length of the hook section 36 is half the width of the neck section 31.
  • Both the hook section 36 pointing away from the insulating material housing 4 and the neck section 31 lying essentially at right angles to the housing base 11 are penetrated by a slot 42 which is open at the edge and extends clearly from the free end 41 of the tab 28 to the contact shoulders 32, 33 .
  • the slot 42 ends essentially at the level of the housing base 11, the distance between the housing base 11 and the contact shoulders 32, 33 being greater than the width of the slot 42.
  • the length of the slot measured from the contact shoulders 32, 33 in the direction of the housing base 11, is greater than the width of the slot 42.
  • slot 42 in the region of the neck portion 31 and in particular in the area between the contact shoulders 32, 33 and the housing base 11 located portion of the tab 28 has a substantially constant width and is thus limited parallel flanks, its width is greater in the region of the hook portion 36.
  • the slot 42 is designed to widen towards the end 41, the flanks of the slot 42 being at an acute angle to one another in this area.
  • the slot 42 is an insulation displacement slot for connecting a line 43 as required, which is indicated by dash-dotted lines in FIG. 2.
  • the line 43 can end at the tab 28 as shown or be continued.
  • two or more lines can be inserted into the slot 42 and thus connected to the tab 28.
  • connection element 1 described so far is attached to the carrier 7 as follows:
  • the carrier 7 is first provided with two spaced-apart openings 45, 46, the center distance of which corresponds to the center distance between the neck portion 31 of the tab 28 and the locking projection 12.
  • the openings 45, 46 are each round, the diameter of the opening 45 being slightly smaller than the width of the neck section 36.
  • the diameter of the opening 46 also provided in the thin-walled, plate-shaped section of the carrier 7 is smaller than the distance of the farthest outwardly projecting sections of the shoulders 16, 17 from each other, so that the locking projection 12 can only be inserted into the opening 46 with elastic bending of the legs 13, 14.
  • the tab 28 protruding from the insulating material housing 4 is inserted with its hook section 36 into the opening 45.
  • the hook section 36 has a width which decreases towards the end 41 and which is smaller than the diameter of the opening 45 over the entire hook section 36. As a result, the hook section 36 can be easily inserted into the opening 45. As shown in FIG. 2, the hook section 36 engages behind the carrier 7. The width of the neck section 31 exceeds the diameter of the opening 45 at the latest, starting from the transition point 37, so that the tab 28 sits with its neck section 31 above the carrier 7 .
  • the lever formed by the tab 28 and the insulating material housing 4 is symbolically indicated in FIG. 2 by a dash-dotted line 48. It can be seen that the distance from the end 41 to the neck portion 31 is substantially less than the distance from the end 41 to the housing-side end of the lever indicated by the dash-dotted line 48. This distance ratio means that a force indicated on the part 3 of the insulating material housing 4, for example in the direction of an arrow 49, is transmitted to the neck section 31 in a considerably increased manner by lever action.
  • the neck portion 31 thereby becomes as soon as the end 41 of the tab 28 abuts the carrier 7 finds, with leverage and destruction at the opening 45, any existing lacquer layers are pressed into the opening 45, for which purpose only a small force which can be easily applied by hand is to be exerted on the insulating material housing 4.

  • the tab 28 is also, as can be seen from FIG. 3, with its end 41 on the back of the carrier 7 without parts of the tab 28 sticking out of the carrier 7. If the tab 28 is designed in such a way that the distance of the end 41 from the plane defined by the contact surface 9 is at a distance which is less than the wall thickness of the carrier 7, the end 41 also bears against the carrier 7 with prestress, whereby the contact point formed between the neck portion 31 and the carrier 7 is additionally mechanically protected.
  • the locking projection 12 sits in the opening 46, the shoulders 16, 17 engaging behind the carrier 7 and securing the insulating material housing 4 thereon.

  • the line 43 slides easily into the slot 42 which widens towards the end 41 in a funnel shape. Because the slot 42 in the region of the neck section 31 is narrower than the diameter of the line 43, the line clamps firmly into the slot at the bending line 34 at the latest . From here on, line 43 cannot penetrate slot 42 without resistance.
  • the neck portion 31 By pivoting the connecting element 1 to the carrier 7 in the manner described above, the neck portion 31 is now inserted into the opening 45, the neck portion 31 forming an insulation displacement contact with the line 43.
  • the neck section receives the line 43 with its slot, the line 43 being permanently deformed in this area and forming an insulation displacement contact with the tab 28. This is, also because of its gas tightness, a permanent and reliable electrical contact. The forces required to establish the connection are low due to the leverage effect. The insulation displacement contact can thus be made by hand without additional tools.
  • the insulating material housing 4, which acts as a lever, and the tab 28 held thereon itself represent a tool for generating the force which is required to achieve the To produce insulation displacement connection both between the tab 28 and the carrier 7 and between the tab 28 and the line 43 connected as required.

  • the insulating housing 4, ie the parts 2, 3 are made of a plastically deformable plastic that holds the pressed-in tab. The result is a mechanically stable connection between the tab 28 and the insulating material housing 4, which in particular absorbs the lever forces which arise when the tab 28 is inserted into the opening 45 without loosening.
