Description

AGING SOCKET FOR A CATHODE RAY TUBE
The present invention relates to an aging socket, and more particularly to an aging socket having an improved enhanced electrode support to which a stem pin is connected so that whole construction thereof is simple and easily disassembled and assembled.
With operation of a manufactured cathode ray tube, very high voltage is applied to an electrode of a final accelerating electrode and a focus electrode of an electron gun. Deterioration of insulation between the electrodes of the electron gun can result in shorts therebetween so that inner circuits and various other components are destructed or destroyed. To prevent this problem by making an easy thermionic emission by increasing an activity of a cathode as a thermionic emission source of an electron gun, an aging processing is performed by burning foreign material in the cathode ray tube by applying voltage predetermined times higher than using voltage to respective electrodes and components to which a predetermined voltage is applied and increasing insulation by an electric polishing.
The aging processing is achieved by connecting an aging socket for applying a predetermined voltage to a stem pin of the cathode ray tube. Hereinafter, the construction of the conventional aging socket is described by referring Figure 1 of to the accompanying drawings.
FIG. 1 is an exploded perspective drawing showing the conventional aging socket. As shown in FIG. 1, the conventional aging socket 1 includes a front panel 10 formed with a plurality of stem pin passing holes 11 at a central portion corresponding to the respective stem pins (not shown) of the cathode ray tube, a connecting terminal plate 20 having a plurality of connecting terminals 21, to which a plurality of connecting pins 22 are fixed on front sides of the connecting terminals 21 and electric wires introduced from the exterior are connected to rear sides, a hollow socket cover 30 formed at a rear side with a wire introducing portion where the exterior wires are introduced, the front panel 10, the connecting terminal plate 20 and the socket cover 30 are assembled by fixing screws 40, and the stem pins are passed through the stem pin passing holes 11 of the front panel 10 so that the respective connecting terminal of the connecting plate 20 is connected to the stem pins one to one. In other words, the whole socket is constructed by assembling the front panel 10, the connecting terminal plate 20 and the socket 30, and the connecting terminal plate 20 is coupled with a plurality of connecting terminals 21 and connecting pins 22 as a construction connecting the stem pins.
However, according to the conventional aging socket 1 as described above, since the front panel 10 is separated from the connecting terminal plate 20, the complexity of the construction makes uneasy for manufacturing, disassembling and assembling. The connecting terminals 21 and connecting pins 22, and the structures for connecting the stem pins, are coupled each other so that the respective locations of the connecting pins 22 connected with the respective stem pins one to one can require one by one adjustment for coupling the connecting terminals 21 and the connecting pins 22. Moreover, several repetitions of the disassembly and the assembly make deformation of the connecting pins 22 likely, the deformation making the connecting pins lose elasticity or resulting in dislocation so that adjustment would be required again.
Moreover, since a number of components forming the socket are required, the manufacturing cost is high leading to increased product costs.
Therefore, it would be advantageous to provide an aging socket for a cathode ray tube having a similar - 3 - structure that is convenient for assembly and disassembly to avoid problems occurring even after repeated connection of the stem pins of the cathode ray tube.
According to the present invention there is provided an aging socket for a cathode ray tube in which a plurality of stem pins of the cathode ray tube can be connected, the aging socket including an electrode support having a stem pin connecting section formed with a plurality of stem pin connecting holes at a central portion so that respective stem pins of the cathode ray tube can be inserted into the stem pin connecting holes by corresponding thereto, a plurality of stem connecting pins connected to the respective stem pin holes at a rear side of the electrode support, and a socket cover connected to the electrode support having an external wire introducing section for receiving an external terminal wire.
The "rear side" of the electrode support is the opposite side of the electrode support to that into which the stem pins are inserted. In this way the stem pins are guided by the connecting holes through the electrode support and into contact with respective stem connecting pins on the opposite side of the electrode support.
A preferred embodiment will now be described by way of example only and with reference to the accompanying drawings, in which: FIG. 1 is an exploded perspective view showing a conventional aging socket; FIG. 2 is a perspective view showing an aging socket for a cathode ray tube according a preferred embodiment of the present invention; FIG. 3 is an exploded perspective view showing the aging socket according to the preferred embodiment of the present invention; FIG. 4 is a perspective view showing the electrode support of the aging socket for a cathode ray tube in 4 FIG. 3; FIG. 4A is a cross sectional view taken along line A-A; in FIG. 4; FIG. 5 is a side view showing a stem connecting pin of the aging socket for the cathode ray tube in FIG. 3; and FIG. 5A is a partial enlarged view showing an internal structure of the stem connecting pin taken along the line B-B' in FIG. 5.
Hereinafter a preferred aging socket 100 for a cathode ray tube according to the present invention in detail by referring to the accompanying drawings.
FIG. 2 is a perspective view showing the aging socket for a cathode ray tube according to the preferred embodiment of the present invention, and FIG. 3 is an exploded view the aging socket for a cathode ray tube according to the preferred embodiment of the present invention.
As shown in FIGs. 2 and 3, the aging socket 100 for the cathode ray tube includes an electrode support 110 having a stem pin connecting section 112 formed with a plurality of stem pin connecting holes 111 at a central portion so that respective stem pins 201 of the cathode ray tube are inserted into the stem pin connecting holes 2 5 111 by corresponding thereto, a plurality of stem connecting pins 120 connected to the respective stem pin holes 111 at a rear side of the electrode support 110, and a socket cover 130 connected to the electrode support 110 having an external wire introducing section 131 in which an external terminal wire is introduced, and assembled by fastening a plurality of fastening bolts 140 passing through at least two fastening holes 141 formed at an outer peripheral of the electrode support. The components of the aging socket may be manufactured from synthetic resin so that the aging socket can be modified in a variety shape.
Hereinafter, the electrode support 110 and the stem - 5 connecting pin 120 of the aging socket 100 described above are described in detail by referring to the accompanying drawings.
FIG. 4 is a perspective view showing the electrode support of the aging socket for the cathode ray tube, and FIG. 4A is a cross sectional view taken along the line A-A' in FIG. 4.
As shown in FIGs. 4 and 4A, the electrode support has a cylindrical body 113, at least two screw fastening holes 141 perforated on outer peripheral from front side of the cylindrical body 113 to rear side thereof, a plurality of stem connecting pin guides 114 extended in a radial direction between a plurality of stem connecting holes 111 formed on the rear side of the cylindrical body 113, and a plurality of installing recess 115 for the stem connecting pin formed between the plurality of the guides 114 and having a shape corresponding to the shape of the stem connecting pins (See FIGS. 2 and 5). Connecting pin separating prevention protrusions 116 and 116' are formed on both upper sides of the stem connecting installing recess 115.
The stem connecting pins 120 are described in detail hereinafter by referring the accompanying drawings.
FIG. 5 is a side view showing the stem connecting pins of the aging socket of the cathode ray tube in FIG. 3, and FIG. 5A is a partial enlarged view showing the internal shape of the stem connecting pins taken along the line B-B' in FIG. 5.
As shown in FIG. 5, the stem connecting pins 120 are cylindrical and bended to a L-shape. The bended horizontal shaft forms an external wire connecting terminal shaft 122 having a cutaway surface 121, which is a surface is cut away at its end portion. The cutaway surface is preferably formed by cutting only one side for decreasing manufacturing process and preventing - 6 waste of material, while hollow vertical shaft receives an elastic coil 124 therein to form a stem connecting shaft 123.
Hereinafter, the operation of the aging socket 100 for the cathode ray tube according to the present invention will be described. The reference numerals are described by referring FIGs. 2 through 5A.
A plurality of stem pins 201 are respectively inserted into the stem pin connecting holes 111 formed on the stem pin connecting section 112 of the aging socket 100, and the external terminal wire (not shown) introduced through the external wire introducing section 131 of the socket cover 130 is connected to the external wire connecting terminal shaft 122. By doing this, a predetermined voltage can be applied so that an aging processing can be performed. Meanwhile, replacement and/or repair of the components such as the stem connecting pins 120 of the aging socket can be simply and easily performed by releasing the fastening bolts 140 in front of the electrode support 110.
Moreover, the connecting terminals and the connecting pins are integrated into the stem connecting pins 120 rather than connecting the separated connecting pins 22 (See FIG 1) to the front end of the connecting terminals 21 (See FIG. 1) as in the conventional art without any change of the function and operation, and the conventional front panel 10 (See FIG. 1) and the connecting terminal plate 20 (See FIG. 1) are also integrated into the electrode support 110 without change of the function and operation so that the construction is more simple.
In addition, the stem connecting pin installing recesses 115 formed within the stem connecting guides 114 are shaped to correspond to the stem connecting pins 120 for connecting the stem connecting pins 120 to the electrode support 110 so that the stem connecting pins are securely connected. By doing this, it can be prevented from foreign material invading around the stem connecting pins 120. Moreover, the connecting pin separating prevention protrusions 116 and 116' are formed on both upper sides of the stem connecting installing recess 115 so that separation of the stem connecting pins 120 can be prevented.
Since the elastic coil 124 having elastic force is inserted inside the stem connecting pins 120, the connected stem pins 201 can be fixed at a predetermined pressure. The cutaway surface is formed only one side of the external wire connecting terminal shaft 122, so that the cost for manufacturing and material can be minimized.
Therefore, according to the preferred aging socket for the cathode ray tube of the present invention, the structure of the aging socket 100 is so simple that the assembly and disassembly of the aging socket is convenient, and all the problems such as deformation of the connecting pins and the connecting terminals of the conventional aging socket occurred at the repetition of the assembly of the stem pins 201 of the cathode ray tube can be solved so that it can be achieved more enhanced effect.
Moreover, since the cutaway surface 121 is formed only on one side of the external wire connecting terminal shaft 122 of the stem connecting pins 120, the cost for the manufacturing and the material can be minimized so that manufacturing cost of the aging socket can be saved.
The present invention has been described in detail.
However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the scope of the invention will become apparent to those skilled in the art from this
detailed description. - 8
