Definitions

  • the invention is based on a plug device with an electrical connector with a contact carrier made of insulating material, which has at least one row of mutually closed, parallel contact chambers, in each of which a flat plug sleeve is arranged, which has a fastening section for a stripped end of an electrical line , has a middle section, a contact section with a contact part and a waist section lying between the fastening section and the middle section.
  • Connectors of the above type are widely known. They comprise a contact carrier and a plurality of contact chambers arranged in parallel and in series, so-called flat plug sleeves being arranged in the contact chambers.
  • This' Flachsteckhulsen have a plurality of functional sections, namely a section Befest Trentsab- to which a stripped wire or an electrical managerial device can be attached by so-called crimping and can be electrically connected with a flat plug sleeve and a central section and a contact section, the contact section being intended to receive a pin which is arranged in a mating connector, so that an electrical connection is established between the connector and the mating connector can be.
  • the tab connector itself is arranged in a contact chamber within the connector in such a way that it is held or fixed in this chamber. It is known from the prior art that a fixation of the tab receptacles can be brought about within the chamber by bringing about a locking in the region of the waist section.
  • the tab connector has a very small distance from the contact chamber wall.
  • a locking slide is known from DE 372 56 88 A, which clamps the tabs inside the contact chamber like a waist.
  • the aforementioned locking takes over the task of absorbing or dissipating the forces occurring on the contact section during the insertion process of the connector on the mating connector, so that almost no forces act on the fastening section or on the waist section.
  • the decoupling of the vibration loads occurring during use of the plug or the mating plug is carried out within the contact part by means of an elastic design, in particular by suitable shaping of the central section.
  • a disadvantage of the previously known fixings or locks is that, in particular when the clamp connection is not fully implemented or when the connection is loose, in particular between a spring element and a contact part, for example caused by shaking movements, inadmissibly high forces occur, which individual elements, in particular the connection between the spring element and the contact part but also the central section is subject to excessive stress, so that its function is not guaranteed.
  • the object of the invention is to provide a simple and secure connection against shaking movement of a flat connector sleeve with a 25 mating connector within a contact chamber.
  • the solution to the problem is that a spring box is arranged on the flat plug sleeve on the side pointing towards the mating plug, which extends over part of the contact part and bears against it, the contact part and spring box being adjacent to a ner positive connection have at least one non-positive connection in the form of a welded connection.
  • a so-called spring cage is pushed onto a configuration of a flat plug sleeve known from the prior art in the region of the contact part and the central section.
  • This spring basket is primarily a stamped part that is additionally bent.
  • the spring cage is attached by means of a suitable fit and held by so-called beads on the blade receptacle. Additional bending processes mean that the spring cage is positively connected to the part of the flat receptacle.
  • the spring cage preferably extends exclusively in the contact area of the flat plug sleeves. It is also conceivable that the spring cage also extends up to the waist section of the flat receptacle.
  • the spring cage itself also has biting devices that point outwards. These are used so that the spring cage can grip in a contact chamber of a connector.
  • the spring cage is additionally connected in a force-locking manner in addition to the positive connection as described.
  • This non-positive connection is established, for example, by a
  • connection between the spring cage and the remaining part of the flat receptacle reached. It is preferably provided that the connection is generated by means of a laser welding point.
  • the laser welding point is advantageously arranged such that it is arranged in the region of the maximum forces that occur. This is the area where the spring cage ends and where the tab receptacle has a waist-like design.
  • Figure 1 shows a multi-pin electrical connector of a connector partially in longitudinal section.
  • Fig. 2 shows a perspective view of a flat plug sleeve together with a spring basket
  • Fig. 3 is a side view, partially a sectional view of the tab receptacles shown in Fig. 2.
  • the connector 1 shown in FIG. 1 has a connector housing 2 and a cover 3 coupled to the connector housing 2.
  • the plug housing 2 comprises a contact carrier 4 which is divided into a plurality of contact chambers 5 arranged parallel to one another and next to one another. Within these contact chambers 5, flat receptacles 6 are provided, which are connected to a wire harness, not shown in the drawing.
  • FIG. 2 such a flat plug sleeve 6 is shown, which can be arranged within such a contact chamber 5.
  • Fig. 3 a sectional view of such a flat plug sleeve 6 is shown together with a spring cage 17.
  • the flat plug sleeve 6 is subdivided into several areas, namely a fastening section 7, a central section 8 and a contact section 9 with a contact part 16.
  • a waist section 10 is provided on the flat plug sleeve between the fastening section 7 and the central section 8.
  • the preferably meandering or wave-shaped tab receptacle 6 provides in the fastening section 7 that a stripped cable or an electrical line between parts of the fastening section 7 and clamping elements 11 is crimped.
  • the tab receptacle runs in a waist-like manner, so that the central section 8 is of a width similar to that of the fastening section 7.
  • the middle section 8 then overflows into a contact section 9 which is designed such that Flachfederarmrome duck can receive a pin 18 of the mating connector 19, so that the electrical contact between connector 1 and mating connector 19 is made.
  • the spring cage 17, which is produced in a punched shape, is designed in such a way that, in the assembled state, it encompasses at least the contact section 9 of the flat plug sleeves 6 and forms a positive connection with the flat plug sleeves at defined points (beads). This means that in order to mount the spring cage 17 on the contact part 16 of the contact section 9, the spring cage 17 can simply be pushed on until the corresponding beads form a connection with one another.
  • a non-positive connection in addition to this positive connection, a non-positive connection can also be established, in which a laser welding point (welded connection 15) is set in particular on the flat side of the spring cage 17 in the region of the contact part 16 such that “ a non-positive connection between the spring cage 17 and the remaining part of the flat receptacle 6 is made.
  • a laser welding point welded connection 15

Abstract

Dispositif enfichable doté d'un connecteur électrique enfichable dans lequel se trouvent des fiches femelles plates situées dans des chambres de contact, lesdites fiches femelles plates formant avec des connecteurs mâles une connexion électrique. Pour protéger lesdites fiches femelles plates contre des défaillances provoquées par des sollicitations vibratoires élevées ou d'autres forces, ledit dispositif comporte dans la zone de la partie de contact (16) de la fiche plate (6) une cage (17) à ressort qui possède, outre des connexions par liaison de forme telles que par exemple des nervures, une connexion par liaison de force avec l'autre partie de la fiche plate (6). Cette connexion par liaison de force est réalisée sous forme de connexion soudée (15), en particulier de soudure par point au laser.
