Definitions

  • the invention relates to a mask frame suspension element. perforated with a cathode ray tube and in particular with a television tube colors.
  • the color television tubes with shadow mask have a glass envelope in which are fixed metal parts, one of which consists of the shadow mask attached to a frame and another by a magnetic shielding placed inside the glass envelope.
  • the glass envelope consists of two parts, a slab comprising the screen on which the image is formed and a cone on which are fixed the electron guns and the deflection coils of the electron beams of the cathode ray tube.
  • the shadow mask is made from a thin metal strip in which holes of small dimensions and of suitable shape are made by chemical machining.
  • the metal bands used are generally low carbon steel or iron-nickel alloy such as Invar.
  • the mask perforated is shaped by hot or cold stamping, so that have a peripheral rim along which a metal frame is welded.
  • the assembly consisting of the frame and the mask is fixed inside the glass slab, by means of suspension devices fixed on the frame and coming to engage on pins sealed in the glass of the slab.
  • the internal shielding of the tube can be fixed either on the mask frame perforated, either on the fixing pins sealed in the glass of the slab.
  • cathode ray tubes of different types which are distinguish in particular by the type of mask or the type of frame used or by the method of hanging the frame inside the glass envelope of the tube.
  • the suspension of the shadow mask, through its frame, to the interior of the glass envelope of the tube must allow filling several functions.
  • this suspension must make it possible to control the relative movements of the glass screen and the shadow mask which are caused in particular by the expansion of the perforated mask which heats up under the impact of the electron beam, so as to maintain the purity of colors of the image formed on the screen.
  • the hanging devices must hold the mask perforated in position inside the glass envelope, even when the tube with cathode rays receives a shock, and protect the shadow mask against external mechanical stresses.
  • suspension systems must make it possible to disassemble or to move the shadow mask during the manufacture of the spoke tube cathodic, then put it back inside the glass envelope, as many times as it may be necessary.
  • the thick frames known from the prior art often have an excessive weight which can be for example of the order of or greater than 2 kg, in the case of so-called "stretched mask” technologies, the shadow mask being tensioned on the frame, the rigidity of which must be sufficient to resist the stresses resulting from the tensioning of the mask.
  • the mask frame suspension elements perforated must be fixed to the mask frame by one or more strong welds, to obtain a satisfactory fixing.
  • the object of the invention is therefore to propose a suspension element of a perforated mask frame inside a slab of a ray tube cathodics comprising a plate crossed by an engagement opening of the suspension element on a pin integral with the slab of the tube to cathode rays and means for fixing the suspension element to a frame wall that can be attached to the seamless mask frame resistant.
  • the suspension element generally designated by the reference 55 includes an amount 56 on which is produced or added a spring 57 projecting from an internal side of the upright 56, a hooking plate 58 connected to the upper edge of the upright, in an inclined arrangement relative to the upright and two fixing tabs 59a and 59b connected to the lower edge of the upright, substantially perpendicular to the upright and having at their end a lug, 59'a and 59'b respectively.
  • the amount includes, depending on its upper edge, two attachment tabs 60a and 60b.
  • the suspension element 55 can be fixed by clipping onto a wall 62 of a mask frame 61 constituting a corner area of the mask, as shown in Figure 1.
  • the mask frame is shown with its sides vertical and its edge for fixing the shadow mask, in its part superior.
  • the hooking lugs 60a and 60b are engaged on the edge top of the corner wall 62 of the mask so that the post 56 comes to bear on the corner wall 62 via the spring 57.
  • the tabs 59a and 59b are slid under the lower edge 63 of the frame 61 opposite the rim on which the shadow mask is fixed.
  • the spring is compressed and the tabs are moved 59a and 59b under the lower rim 63 of the mask until the pins 59'a and 59'b engage in openings provided in a desired position through the rim 63.
  • the pins 59'a and 59'b of the tongues 59a and 59b could, alternatively, come to engage, in the position of fixing of the suspension element 55, on the inner edge of the rim 63.
  • the the suspension element 55 is fixed to the frame 61 by clipping, the spring 57 being compressed against the corner wall 62 of the frame and exerting a tensile force on the tongues 59a and 59b including the pins 59'a and 59'b are engaged in openings or against the internal edge of the ledge 63.
  • the suspension element which is also hung on the upper edge of the frame by the legs 60a and 60b is perfectly fixed on the frame. Eventually, the fixing of the suspension element can be completed by a laser or electric welding point.
  • the attachment plate 58 is crossed by an opening 64 which is engaged on an anchor pin 65 sealed in an internal part of the slab cathode ray tube, near a corner of the slab.
  • the suspension element 55 can be obtained by cutting and folding a thin metal blade, as shown in the figure 3 where the cutting lines of the metal strip have been shown in solid lines and the dotted fold lines.
  • the suspension element 55 could also be produced in several parts assembled together by welding.
  • All these steels and alloys have been retained because they have a high elastic limit and that they keep their elasticity following the treatments necessary heat, during the production of color television tubes.
  • the alloys used must preferably be non-magnetic.
  • Suspension elements such as element 55 shown in the Figures 1 and 2 have the advantage of being able to be fixed on a frame of shadow mask without the need for a welded connection resistant. Therefore, the suspension elements can be easily disassembled so well that it is possible in the event that during manufacture of the frame, a check shows that the frame is not in conformity, to recover the frame and / or suspension elements. In addition, seamless fixing of the suspension element on a rigid and light frame avoids deforming the frame when fixing the element.
  • suspension element as described above is of a simple and inexpensive production and can be set up and fixed to the frame mask quickly and easily.
  • the suspension element according to the invention can comprise a single tab and a single hooking tab on the shadow mask frame or more than two legs and more than two hooking tabs.
