Definitions

  • the invention relates to a connector arrangement for connecting a display unit to a printed circuit board, in particular in a hand-held electronic device.
  • a passive display unit especially of the liquid crystal (LCD) type, in which a so-called light guide is provided for background lighting.
  • LCD liquid crystal
  • LCD display units are largely designed as LCD display units with a control circuit (LCD controller) placed on the glass body or the display glass (also referred to as “LCD panel”).
  • LCD controller control circuit
  • LCD panel display glass
  • Such an integral display unit must be electrically connected to the circuit board of the electronic device carrying the other electronic components.
  • the connection comprises a large number of individual connections and is therefore also referred to as a “multi-pole” electrical connection. It is known to establish this connection via a flexible line (“flexible line”, also abbreviated as “FPC”), which is soldered to the printed circuit board, glued with conductive adhesive or connected via a connector.
  • FPC flexible line
  • solddering and gluing are connection types that are complex in terms of production technology, over which the plug-type contact is to be preferred in principle.
  • a plug connection is carried out by hand by inserting the flexible line into the connector. This procedure is labor intensive and the connector suitable for manual assembly must be relatively large.
  • the flexible line for safe manual handling must be relatively long, which increases the material costs.
  • the invention is based on the object of providing such an improved connector arrangement.
  • the invention includes the essential idea that
  • connection element which has a plurality of (internal) first contact surfaces. It also includes the idea of the flexible line, known per se, which is firmly connected at a first end to the display unit — specifically its control unit (electrically) and mechanically — and a plurality of second ones at its second end Has contact surfaces, at this second end mechanically essentially rigidly connected to the display unit as a prefabricated assembly. According to a third essential aspect of the invention, this enables the second end stiffened by the connection to the display unit to be securely inserted into the connection element on the printed circuit board in an automated assembly process.
  • the display unit is a passive display unit with backlighting, in particular of the LCD type.
  • a display unit has a light guide element for backlighting that is mechanically firmly connected to it (for example by means of light-emitting diodes), and the second end of the flexible line is at least indirectly rigidly connected to this light guide element.
  • this rigid connection is established via a special carrier element which is firmly connected on the one hand to the light guide element and on the other hand to the second end of the flexible line. At least one of these fixed connections is designed as an adhesive connection in a cost-effective and technologically simple manner.
  • the connection between the carrier element and the light guide element is a positive connection, for example of the tongue and groove type.
  • the carrier element is preferably essentially plate-shaped. In this embodiment, perpendicular to the plate level, it has a bending elasticity that can be adjusted by the choice of material and dimensions, which helps to compensate for minor manufacturing tolerances in the components to be connected to one another or also a play in the handling device for assembly.
  • the flexible line is additionally mechanically connected to the glass body (LCD panel) of an LCD display device at or near its second end, again in particular by gluing.
  • the flexible line is expediently guided essentially S-shaped between its first end, which is mechanically and electrically connected to the display device, and its second end, which is inserted in the connecting element on the printed circuit board.
  • the electrical connections are largely mechanically relieved, and this course also helps to compensate for tolerances of the components or a play of the handling device.
  • the light guide element has a position and at least the lateral dimensions corresponding to the connecting element of the recess (socket strip). If the support element is positioned with the second end of the flexible line in this recess, the recess of the light guide element assumes the function of a guide for the second end of the flexible line towards the connection element and in the assembled state.
  • the light guide element expediently has a slight play compared to the connection element to compensate for the tolerances mentioned, the implementation of the first and / or second contact surfaces (preferably the first contact surfaces on the connection element) as spring elements being reliable under all practical circumstances electrical connection between the circuit board and the second end of the flexible line is ensured.
  • FIGS. 1 a and 1 b connector arrangements according to a first embodiment of the invention in the unassembled or in the assembled state, in schematic cross-sectional representations,
  • FIG. 2 shows a cross-sectional representation to explain a second embodiment of the invention (in the assembled state) and FIGS. 3a and 3b show schematic representations to explain a third embodiment in two greatly simplified cross-sectional representations.
  • Cross-sectional view of a portion of a mobile phone 100 namely a connector 110 for connecting an LCD display unit 120 to a circuit board 130.
  • the LCD display unit 120 comprises, in addition to the actual display element (LCD panel) 121, which essentially consists of two glass plates provided on the inside with conductor track coatings and a liquid crystal layer between them, a LCD control unit 122 and a so-called light guide 123, which together with LEDs is used for backlighting.
  • LCD panel essentially consists of two glass plates provided on the inside with conductor track coatings and a liquid crystal layer between them
  • a LCD control unit 122 essentially consists of two glass plates provided on the inside with conductor track coatings and a liquid crystal layer between them
  • a so-called light guide 123 which together with LEDs is used for backlighting.
  • an approximately U-shaped socket strip 131 is placed as a connection element, which has a plurality of serially arranged contact springs 131a in a plastic body 131b.
  • the connections between the contact springs 131a and conductor tracks on or in the printed circuit board (PCB Printed Circuit Board) 130 are not shown.
  • the connector 110 is designed as a flexible line or with a first end 110a on the LCP panel 121 mechanically attached and electrically connected to the LCD control unit 122.
  • a second end 110b is glued flat to a carrier plate 111, which in turn is glued to the latter in a recess area 123a of the light guide 123.
  • the support plate 111 is much thinner than the light guide 123, and its plate plane extends parallel to that of the light guide 123 and the LCD panel 121.
  • first and the second end 110a, 110b of the flexible line (the connector) 110 there is an essentially S-shaped course.

  • the thickness of the carrier plate 111 and the flexible line 110 together is less than the height of an interior 131c of the socket strip 131 which is U-shaped in cross section, but slightly larger than the free height up to the lower surface of the contact springs 131a.
  • the position of the “plug” formed from the carrier plate 111 and the second end 110b of the flexible line 110 in the vertical and lateral directions corresponds to the height of the interior 131c of the socket strip 131 above the surface of the printed circuit board 130 and to its lateral arrangement thereon.

  • the latter elastically print on corresponding contact surfaces 110c at the second end 110b of the connector 110. This ensures both a secure contact between the contact surfaces 131a, 110c as well as a non-positive connection between the socket strip 131 and the carrier plate connector 111/110.
  • the S-shaped course of the connector 110 offers the space required for pushing the connector strip 131 under the LCD panel 120 and ensures that the electrical contacts at both ends 110a, 110b of the connector 110 are mechanically relieved and slight manufacturing tolerances of the components are compensated for ,
  • FIG. 2 shows an embodiment slightly modified compared to FIGS. 1 a and 1 b, which results from the modified design of an LCD display unit 120.
  • a connector 110 ⁇ with a different shape is also provided, while the other components are unchanged and are therefore designated with the same reference numbers as m FIGS. 1 a and 1 b.
  • the LCD panel 121 ⁇ here has a projecting (not specifically designated) lower glass plate, the LCD drive unit 122 being attached to the surface (instead of the lower glass plate as in FIGS. 1 a and 1 b). Accordingly, the upper leg of the S-shaped course of the flexible line 110 is expanded in such a way that it encompasses the lower plate of the LCD panel 121 x . Since, moreover, the design and function of the connector arrangement coincide with that according to FIGS. 1 a and 1 b, the corresponding description is not repeated here.
  • FIGS. 3a and 3b show an arrangement, modified again compared to FIG. 2, of a printed circuit board 130 and an LCD display unit 120 "for a mobile phone 100" modified with regard to the design of a light guide 123 "and a carrier plate 111".
