Definitions

  • the invention relates to a holding frame for a connector for receiving several contact inserts, with two opposite side parts and two opposite end parts, the two end parts being arranged perpendicular to the side parts, with at least one elastic tab being provided on each of the two side parts and with the tabs each have a latching means for fixing a latching projection of a contact insert inserted into the holding frame, at least one end part consisting at least partially of an electrically conductive material and having a PE connection.
  • Such holding frames are used to accommodate a plurality of contact inserts which can be inserted into the holding frame and which consist of an insulating body with a rectangular cross section, in which different contact elements can be arranged. Because the contact inserts can be inserted individually into the holding frame, it is possible to equip a holding frame with different contact inserts, depending on the intended use.
  • the holding frame with the contact inserts is thus constructed in a modular manner, so that the contact inserts are also referred to as contact insert modules or contact modules.
  • the fully equipped holding frame, in which the respective contact inserts are inserted can be inserted into a housing part of a plug connector and fastened therein, the plug connector being used for fastening with a corresponding mating plug connector.
  • holding frame Various types of holding frame are known from practice, which allow a modular insertion of individual contact inserts.
  • holding frames that consist of two articulated frame halves, the contact inserts being inserted into corresponding recesses in the holding frame when the holding frame is open and being positively held in their position when the holding frame is closed.
  • holding frames that have a fixed base frame in which the individual contact inserts are also inserted into corresponding recesses in a first step.
  • a fastening bracket is fixed to the base frame in a second step.
  • the mounting bracket engages over projections that are formed on the end faces of the contact inserts and engage in corresponding recesses on the upper edge of the base frame.
  • a holding frame for a connector which is formed in one piece and consists of a plastic material.
  • the two opposing side walls of the holding frame have a plurality of elastic wall segments separated by slots, in each of which a window-like opening is formed.
  • a contact insert with its locking projections formed on the end faces can be pushed between two opposing wall segments until the two locking projections lock into the opposing window-like openings.
  • the disadvantage here is that the holding frame is made entirely of plastic, so that it is not suitable for protective grounding when the holding frame is installed in a metallic connector housing.
  • the DE 10 2015 103 563 A1 discloses a holding frame made of an electrically conductive material, which consists of a rigid, rectangular base frame with two side parts and two end parts, with upwardly open recesses formed on the upper edge of the side parts, which are laterally bounded by webs that extend parallel to the direction of insertion of a Extend contact insert.
  • a plurality of resilient tabs separated from one another by slots are attached to the two side parts, for which purpose the lower sections of the slots are bent over by 180 ° around the lower edge of the corresponding side wall of the base frame.
  • the tabs each have a holding tongue in their bent-over section, which engages in a corresponding holding opening in the side part.
  • a recess is formed in each of the tabs, the tabs being arranged on the side parts in such a way that the recesses in the tabs and the recesses in the side parts are aligned with one another.
  • the upper edge of the recesses is delimited in each case by a bracket section on which an inwardly protruding locking lug is formed.
  • the latch protrudes into the respective recess of a side part, so that the latching projection of a contact insert inserted in the holding frame is overlapped by the latch formed on the tab.
  • the lower edge of the locking projection lies on the lower edge of the recess of the side part, while the side edges of the locking projection are held by the webs laterally delimiting the recess.
  • the tabs are preferably made of a resilient sheet metal, so that the tabs have corresponding resilient properties that allow the contact inserts to be inserted between two opposing tabs until the latching projections formed on the contact inserts are overlapped by the inwardly protruding latches formed on the tabs thereby be fixed in the holding frame.
  • the front parts which consist of an electrically conductive material, in particular sheet metal, each have a flange section on which a PE connection is formed.
  • the PE connection has a screw connection so that a protective conductor can be electrically connected to the connection contact of the PE connection with the aid of the screw connection.
  • a holding frame designed in this way enables the contact inserts to be fastened in the holding frame in a simple and, at the same time, secure manner, and individual contact inserts can also be exchanged without any problems.
  • the assembly is somewhat complex, especially if a protective conductor is to be connected in confined spaces.
  • the present invention is therefore based on the object of providing a holding frame that is as simple as possible to manufacture and that enables the simplest possible assembly.
  • the PE connection has a screwless connection device and a metallic connection contact which is electrically conductively connected to the connection device. Because the at least one PE connection in the holding frame according to the invention does not have a screw connection but a screwless connection device, the effort involved in connecting a protective conductor is reduced. This also simplifies the assembly of the holding frame, which is associated with a shortening of the assembly times for the individual holding frames.
  • a screwless connection device a cutting connection can be provided, for example, in which the end of an insulated conductor be inserted between two opposing cutting edges of a metallic connection element.
  • the screwless connection device is designed as a spring-loaded terminal connection which has a clamping spring and a contact piece.
  • a loop-shaped tension spring can be used as the clamping spring, with the aid of which a conductor arranged in an opening in the clamping leg of the tension spring is clamped against a busbar piece.
  • a leg spring is used as the clamping spring, which has a clamping leg and a retaining leg, which are connected to one another via a spring arch.
  • the clamping leg of the clamping spring forms with the contact piece a clamping point for the protective conductor to be connected by the stripped end of the protective conductor being pressed by the clamping leg against the contact piece, which is electrically connected to the connection contact.
  • the advantage of a spring-loaded terminal connection with a leg spring as the clamping spring is that no additional assembly step is required to connect a rigid conductor.
  • the end of a rigid conductor can simply be inserted into the terminal point, since the clamping leg is deflected from the end of the rigid conductor when it is inserted. If the protective conductor to be connected is plugged into the terminal point, it is securely held by the end of the terminal leg running obliquely to the direction of insertion of the conductor, so that the conductor is prevented from being unintentionally pulled out of the terminal point.
  • the design of the PE connection as a spring-loaded terminal connection can be implemented in a particularly simple manner in that the contact piece, against which the conductor to be connected is pressed by the clamping leg of the clamping spring, is designed in one piece with the front part. If the front part consists, for example, of sheet metal, in particular a steel sheet or a sheet made of a copper material, the contact piece can simply be punched free from the front part and bent. If, on the other hand, the end part is designed as a die-cast part, in particular as a zinc die-cast part or as an aluminum die-cast part, then the contact piece is preferably molded directly onto the end part in the die-casting process.
  • a housing part is arranged at least on the end part that has a PE connection.
  • the housing part can be attached to the front part, preferably by means of corresponding latching elements.
  • the housing part which consists of an insulating material, has a conductor entry opening for inserting the protective conductor to be connected and, moreover, preferably also an actuation opening for opening the terminal point.
  • a protective conductor is not only pressed against the contact piece by the clamping leg, whereby an electrically conductive connection is established between the free end of the protective conductor and the contact piece, but the protective conductor is also protected against an unwanted one by the free end of the clamping leg Prevented pulling out of the clamping point.
  • the clamping leg of the clamping spring In order to deliberately release a connected conductor from the clamping point or the spring-loaded terminal connection, the clamping leg of the clamping spring must be deflected against its spring force.
  • a corresponding actuating tool for example the end of a screwdriver, can be inserted through the actuating opening into the housing part, the actuating opening being arranged in relation to the clamping spring in such a way that the clamping leg is deflected against its spring force when the actuating tool is inserted and is thus lifted off the connected conductor.
  • an actuating element is arranged in the actuating opening for opening the clamping point, which actuating element can be brought from a first position in which the clamping point is closed into a second position in which the clamping point is open. In the second position of the actuating element, the clamping leg of the clamping spring is deflected by the actuating element against its spring force.
  • the actuation element can be, for example, a pivotably mounted actuation lever or an actuation lever arranged displaceably in the actuation opening.
  • not only the contact piece for the clamping point, but also a fastening element for the clamping spring and preferably also a stop element for the clamping leg of the clamping spring is formed on the end part, which has a PE connection.
  • the formation of a corresponding fastening element ensures secure positioning and holding of the clamping spring, in which case corresponding contact sections for the clamping spring can also be formed in the housing so that the clamping spring is safely and functionally supported and positioned by the end part and the housing part.
  • the formation of an additional stop element on the front part has the advantage that the clamping leg of the clamping spring is thereby protected against excessive deflection, which could damage the clamping spring or impair the spring properties.
  • the holding frame according to the invention can in principle have a one-piece base frame which is formed by the two side parts and the two front parts.
  • a base frame is then preferably designed as a die-cast part, for example as a zinc die-cast part or an aluminum die-cast part.
  • the two side parts and the two end parts are initially designed or manufactured as separate components before the two side parts are firmly connected to the two end parts, in particular welded, soldered, riveted or stamped together.
  • the individual components that is to say the side parts and the front parts, are preferably made of sheet metal, for example a sheet steel or a sheet made of a copper material.
  • the side parts and the front parts preferably have interlocking contours at the connection points, so that the side parts and the front parts can first be put together or plugged together before they are permanently connected to one another at the connection points by welding, soldering, riveting or stamping.
  • the design of interlocking contours has the additional advantage that, in addition to a force fit or material fit, a form fit is also generated at the connection points.
  • the formation of the holding frame from several separate components also has the advantage that, in this way, different holding frames can be produced in a simple manner, which are provided for receiving different numbers of contact inserts.
  • a holding frame which is intended to hold six contact inserts
  • only different, correspondingly longer side parts then have to be used compared to a holding frame which is intended to hold four contact inserts, while the same end faces can be used for both holding frames.
  • the individual side parts can preferably be made from an endless punched strip that is punched for different lengths depending on the size of the holding frame to be manufactured.
  • the tabs on the side parts each have a locking means.
  • the latching means can be, for example, recesses or latching windows in the tabs.
  • two holding elements are formed as latching means on the upper region of the tabs in the insertion direction E of a contact insert, the holding elements extending perpendicular to the insertion direction E in the opposite direction outward from the upper region of the tab.
  • the tabs are arranged on the side parts in such a way that in each case one tab is arranged at least with its upper area between two locking projections, so that the holding elements at least partially overlap the locking projections of the contact inserts when the contact inserts are inserted into the holding frame.
  • Such a holding frame then also differs from the holding frame known from the prior art in that two holding elements are formed as latching means on the individual tabs, the two holding elements interacting with two latching projections of the contact inserts.
  • the individual tabs have only one latching means, so that each tab also only interacts with one latching projection of a contact insert, regardless of whether the latching means is designed as a latching window or as a latching lug.
  • the two latching projections which are at least partially overlapped by the two retaining elements of a tab, can either be formed on two contact inserts, which are arranged next to one another in the retaining frame, or on a contact insert, which then has a double width.
  • a latching projection formed on its end face is overlapped by at least one holding element of a bracket. If the contact insert is located between two tabs, its latching projection is overlapped by one holding element of the two tabs, that is to say by a total of two holding elements.
  • the holding elements preferably have a length perpendicular to the insertion direction E of the contact inserts, which is only slightly less than the corresponding extension of a latching projection of a contact insert, so that only a small amount of space remains between two holding elements of two adjacent tabs that jointly overlap a latching projection.
  • the holding elements of the tabs are preferably designed or arranged in such a way that they form an insertion bevel for a latching projection of a contact insert.
  • Such an insertion bevel can be implemented, for example, in that the holding elements are arranged at a small angle to the insertion direction E or to the longitudinal extension of the tabs on the upper region of the tabs. The holding elements are thus slightly inclined with respect to the insertion direction E.
  • more than one tab for example two, three, four, five or even more tabs, are provided on both side parts.
  • the at least one tab is preferably designed in one piece with the respective side part, so that fastening of the tabs to the side parts is not necessary, which means that a corresponding work step can be omitted.
  • the tabs are then preferably formed on the upper edge of the side parts.
  • the respective side part and the tabs formed thereon are then essentially flat, which is advantageous due to the generally limited installation space for a holding frame in a housing part of a connector.
  • two shoulders are formed on the tabs, each of which is located at a distance below a holding element.
  • the distance between a shoulder and the opposing holding element is selected so that the latching projection of a contact insert inserted in the holding frame rests on the shoulder and thereby is at the same time partially overlapped by the holding element.
  • shoulders are formed on the tabs, which serve to support the latching projections of the contact inserts, the extension of the tabs can be selected to be relatively large.
  • the brackets in the holding frame are designed as separate components or in one piece with the side parts
  • the brackets of one side part preferably have a different width in their upper area than the brackets of the other side part.
  • the formation of, at least in the upper area, tabs of different widths on the two opposite side parts means that the distance between two adjacent tabs in the upper area on the two side parts is also different. In this way, a coding can be created for the individual slots which only enables the contact inserts to be inserted in exactly one orientation if the latching projections provided on the contact inserts also have a different width on the two end faces.
  • FIGs 1 and 6th show two different design variants of a holding frame 1 according to the invention, each in a perspective view, obliquely from above, the side of the holding frame 1 from which a contact insert 2 is inserted into the holding frame 1 in the insertion direction E is referred to as "top".

  • the holding elements 23 are bent away from the tabs 5, 5 ′ in such a way that the holding elements 23 run somewhat inclined to the insertion direction E.
  • a contact insert 2 can thus simply be inserted between two mutually opposite tabs 5, 5 ', the tabs 5, 5' somewhat are deflected outward when the locking projections 6 slide along the holding elements 23.
  • the tabs 5, 5 ' are formed in one piece with the side parts 3, 3'.
  • the tabs 5, 5 ' are integrally formed on the upper edge 25 of the sides 3, 3', the tabs 5, 5 'extending from the upper edge 25 opposite to the insertion direction E.
  • two shoulders 26 are formed on each of the tabs 5, 5 ′, each of which is located somewhat below a holding element 23.
  • the free distance between the shoulders 26 and the holding elements 23 is adapted to the corresponding height of the latching projections 6 of the contact inserts 2.
  • the latching projections 6 rest on the shoulders 26 of the tabs 5, 5 ′ and are at the same time partially overlapped by the holding elements 23.
  • the two end parts 4, 4 'of the holding frame 1 are of identical design. This simplifies the production of the holding frame 1.
  • the two opposite side parts 3, 3 ' differ in that the tab 5 of one side part 3 is wider in its upper area 24 than the tab 5' of the other side part 3 '. This leads to the fact that the distance between the tab 5 of one side part 3 and the two front parts 4, 4 'is less than the distance between the tab 5' of the other side part 3 'and the front parts 4, 4'.
  • This allows coding for the individual slots so that the contact inserts 2 can only be inserted in exactly one orientation if the latching projections 6 provided on the contact inserts 2 are also of different widths on the two end faces.
  • the side parts 3, 3 'on the one hand and the tabs 5, 5' on the other hand can also have a different elasticity when the tabs 5, 5 'and the side parts 3, 3' are formed integrally with one another or the separate tabs 5, 5 ' consist of the same material as the side parts 3, 3 '.
