Definitions

  • the invention is based on an insulating body, in particular for a heavy-duty plug connector, according to the preamble of independent claim 1.
  • the invention is based on a kit with such an insulating body and at least one screw contact and at least one contact screw and at least one crimp contact.
  • the invention is based on a connector module.
  • the invention is based on a modular connector system.
  • the invention is based on a contact insert.
  • the invention is based on a connector.
  • Such insulators are required in order to receive electrical plug contacts electrically isolated from one another and from their surroundings, in particular electrically isolated from a surrounding metallic connector housing, in through openings provided for this purpose, namely so-called contact chambers, and with a sufficient holding force which at least withstands the insertion forces that occur during the plugging process to fix in it.
  • an electrically conductive connection on the cable connection side of the plug contacts with an electrical conductor each and their plug-in electrical connection with mating plug contacts of a mating connector should be made possible.
  • Such an insulating body can be part of a contact insert, which is usually provided to be installed directly in a connector housing.
  • the contact insert can then, for example, have the insulating body with two grounding elements and plug contacts inserted into the insulating body.
  • Such an insulating body can, however, also be part of a connector module.
  • Such connector modules are used in corresponding holding frames, which are sometimes also referred to as hinged frames, module frames, modular frames or modular connector frames. These holding frames are used to accommodate several connector modules of the same type and / or different from one another and to secure them securely to a surface and / or a device wall and / or to install them in a connector housing, in particular in a metallic heavy-duty connector housing.
  • Connector modules are therefore required together with the said holding frame as part of a modular connector system in order to flexibly adapt a connector, in particular a heavy industrial connector, to certain requirements with regard to signal and energy transmission, for example.
  • the connector modules can have latching means, in particular latching lugs, on the narrow sides of their substantially cuboidal insulating body, for fastening in corresponding receptacles, e.g. B.
  • latching means in particular latching lugs
  • the holding frame can have locking windows, the holding frame.
  • the locking lugs of the two opposite narrow sides can differ, for. B. be of different widths, and the corresponding locking window on two opposite side parts of the holding frame can correspond to this shape, so that the correct alignment, namely the so-called "polarization" of the connector modules in the modular connector frame is guaranteed.
  • Connector modules can have various types of plug contacts and fix them within their insulating bodies.
  • the function of a connector that has a modular connector system is therefore very flexible. It can, depending on the design and the type of their contacts, for.
  • electrical contacts that are suitable for the transmission of electrical energy that is, z. B. are designed for particularly high electrical voltages and / or for particularly high electrical current transmission, be part of such a modular connector system. Therefore, the connector with its housing and its grounding, as well as the air and creepage distances made possible by its design, should meet the requirements of a heavy-duty connector.
  • hinged frames are often used as holding frames for modular connector systems. These hinged frames are made of formed two frame halves which are hinged together. Said latching windows are provided in the side parts of the frame halves, into which the latching lugs dip when the connector modules are inserted into the holding frame. To insert the connector modules, the holding frame is unfolded, ie opened, with the frame halves around the joints only being opened so far that the connector modules can be inserted. The frame halves are then capped together, ie the holding frame is closed, the latching lugs reaching the latching window and a secure, form-fitting hold of the connector modules in the holding frame. Recently, particularly advantageous hinged frames have also become known which lock in the open state as well as in the closed state in order to facilitate operation.
  • one-piece plastic frames can also be used as holding frames for certain applications and protective earthing classes. H. perpendicular to the frame plane, permitted, in which they are nevertheless kept stable in the frame plane.
  • the desired elasticity of the various areas can be achieved in particular by means of the material thickness in the corresponding areas.
  • modular connector frames can be used, each with a rigid base frame, the base frame ideally considered rigid and z. B. are made by zinc die casting, and each with one or more flexible cheek parts, z. B. stamped and bent parts made of resilient sheet metal are provided.
  • Such modular connector frames have the advantage that the connector modules can be inserted into the modular connector frame with little effort and that they are made of metal at the same time in order to enable protective grounding (PE).
  • the document DE 102018 118774 A1 discloses a plug connector which essentially consists of an insulating body and at least one contact element.
  • the contact element is fastened directly in the insulating body, the insulating body at the same time forming the connector housing of the connector.
  • the connector is therefore particularly simple and can be assembled quickly.
  • the connector has a very robust design and is suitable for industrial use, especially in harsh environments.
  • the document discloses both designs that are suitable for the use of screw contacts and designs that are suitable for the use of crimp contacts.
  • the use of a retaining plate is disclosed for fixing the contact elements.
  • a disadvantage of this prior art is that insulating bodies which already exist on the market and which are provided for receiving screw contacts cannot accommodate crimp contacts and cannot fix them with sufficient holding force.
  • Another disadvantage is that different insulating bodies have to be designed and manufactured for crimp contacts and screw contacts, which is costly and does not correspond to the principle of ergonomic mass production and ergonomic component and spare parts storage. This creates unnecessary manufacturing and storage costs and the associated costs.
  • the German Patent and Trademark Office researched the following prior art in the priority application for the present application: DE 102018 106880 A1, DE 102013019695 A1, US 2018/0294597 A1 and CN 207559 104 U.
  • the object of the invention is to provide an insulating body that can accommodate electrical plug-in contacts both in the form of screw contacts and in the form of crimp contacts and fixes them in a sufficiently stable manner, in particular for use in a heavy-duty connector, to absorb the insertion forces occurring during the plugging process.
  • the electrical plug contacts can be pin contacts as well as socket contacts.
  • An insulating body has a contact carrier and a holding plate that can be locked with it.
  • the contact carrier has two mutually opposite longitudinal sides, oriented in a longitudinal direction of the insulating body, and two mutually opposite narrow sides oriented perpendicular thereto.
  • the insulating body has a cable connection and a plug side perpendicular to the long and narrow sides.
  • the contact carrier has contact chambers which run in the plugging direction and connect the cable connection side with the plugging side.
  • a first group of contact chambers is arranged in the vicinity of one of the longitudinal sides and a second group of contact chambers is arranged in the vicinity of the other longitudinal side.
  • the contact chambers of the first group and the contact chambers of the second group are arranged offset from one another in the said longitudinal direction. This is advantageous in order to provide sufficient installation space in the contact carrier for the screw connection mechanism described below:
  • the contact chambers are designed to be cylindrical at their plug-in end. At their end on the cable connection side, the contact chambers each have, in addition to their cylindrical shape, a laterally adjoining screw connection receptacle. This screw connection receptacle points in the direction of the respective opposite longitudinal side. Furthermore, the screw connection receptacle for fixing and contacting on the cable connection side of a screw contact arranged or to be arranged in the contact chamber is opened by means of a contact screw through a screw feedthrough running in the direction of said opposite longitudinal side to this opposite longitudinal side.
  • the holding plate has an essentially rectangular base plate, on which two side plates, which are opposite one another and point in a common direction, are formed on the longitudinal side.
  • latching elements for said latching of the holding plate on the contact carrier are arranged.
  • these locking elements can be locking tabs which have an inwardly angled or bent locking section at their free end and which are used for locking with the contact carrier, in particular at an edge of its cable connection side.
  • the base plate of the retaining plate comes to rest on the cable connection side of the contact carrier. Furthermore, in the Base plate arranged contact bushings, which are arranged in the locked state over a contact chamber. In this locked state, the base plate engages with a locking arm arranged on its contact bushings in the screw connection receptacle of the respective contact chamber of the contact carrier in order to fix a crimp contact introduced or to be introduced into the contact chamber.
  • this insulating body can be used both in combination with screw contacts and in combination with crimp contacts. This can take place particularly advantageously in the form of a modular system, which saves storage and positioning costs on the manufacturer side and at least storage costs on the customer side.
  • the retaining plate according to the invention has to be snapped onto a contact carrier which is suitable for receiving screw contacts in order to enable it to receive crimp contacts. From the manufacturer's point of view, it is particularly advantageous that the contact carrier can be a product that already exists on the market, which is retrofitted with the holding plate for receiving crimp contacts, that is, this additional application is enriched by the holding plate.
  • two naturally different contact carriers belonging to a plug-in system namely a pin contact carrier for receiving pin contacts and a socket contact carrier that can be plugged in therewith for receiving socket contacts, can be made capable of receiving crimp contacts by just one type of retaining plate.
  • This is particularly advantageous because it only keeps holding plates of one design for the entire plug-in system will need. Due to structural differences between the pin and socket contact carriers, however, it can also make sense to design the retaining plate in two variants, i.e. in one design for the pin contact carrier and in another design for the socket contact carrier. For example, these two designs of the holding plate can be designed mirror-inverted to one another.
  • pin and socket contacts relate to the design of the plug-in area of the respective plug-in contact.
  • the term “crimp and screw contacts”, on the other hand, relates to the cable connection area and the type of connection of an electrical conductor.
  • a crimp contact can therefore be designed as a pin or socket contact.
  • a screw contact can also be designed as both a pin and a socket contact.

  • the contact carrier can also be used in combination with the retaining plate and crimp contacts.
  • the crimp contacts are usually pre-assembled, that is to say pressed onto electrical conductors, in particular on strands, of an in particular multi-core electrical cable, ie. H. crimped. In the pre-assembled state, they can be guided through the contact guides of the said baseplate locked to the contact carrier and thus inserted into the contact chamber of the contact carrier from the direction on the cable connection side. They have a retaining collar with which they hit a feed stop of the contact chamber when inserted, which prevents further insertion in the direction of the plug-in side. They are held against forces acting in the direction of the plug-in side, in particular by an inner collar acting as a feed stop on the inside, that is to say a tapering of the contact chamber.
  • the retaining plate can lock with their retaining collar on said locking arm of the retaining plate. In the direction of the cable connection side, they are held by the locking arm on which they are locked.
  • the locking arm allows, according to the principle of a barb, to insert the crimp contact from the direction of the cable connection side, but prevents the crimp contact from moving out in the opposite direction towards the cable connection side, e.g. B. when high insertion forces occur or, for example, due to high cable tensile forces.

  • a latching lug for latching in latching windows of a holding frame can be formed on each of the two narrow sides of its contact carrier. Due to the ability of the insulating body to accommodate and fix both crimp and screw contacts, the modular connector system can then also be expanded to include this option with little production, storage and material expenditure.
