Definitions

  • the present invention relates to a cathode ray tube or CRT socket comprising a housing, a focus connection contact and a focus spark-gap contact along with other necessary contacts together built in the housing.
  • Figs. 8(a) and 8(b) and 9 show a soldering type CRT socket
  • Figs. 10(a), 10(b) and 11 show a press contact or snap-in type CRT socket.
  • Either type of CRT socket comprises a housing 5 or 15, a focus connection con­tact 1 or 11 and a focus spark-gap contact 2 or 12 along with other necessary contacts (not shown) all together built in the housing.
  • the focus connection contact 1 or 11 is connected to the focus spark-gap contact 2 or 12 and a high-voltage lead con­ductor 4 or 14.
  • the terminal extension 1a of the focus connection contact 1 is laid on the terminal extension 2a of the focus spark-gap contact 2 with their apertures 3 registering in alignment.
  • the core conductor end 4a of the high-voltage lead conductor 4 is inserted in the register­ing apertures 3, and then the core conductor end 4a is soldered to the terminal extensions 1a and 2a of the contacts 1 and 2, as seen from Figs. 8 and 9.
  • the terminal extension 11b of the focus connection con­tact 11 has a folded end
  • the terminal piece 12b of the focus spark-gap contact 12 has a counter wall.
  • These contacts 11 and 12 are arranged with the folded end of the focus connection con­tact 11 pushed resiliently against the counter wall of the focus spark-gap contact 12.
  • the core conductor end 14a of the high-­voltage lead conductor 14 is press-fitted between the folded end of the focus connection contact 11 and the counter wall of the focus spark-gap contact 12.
  • a spark-gap electrode is indicated at 2c and 12c.
  • each different type CRT socket requires a focus connection contact and a focus spark-gap con­tact, which are designed to be exclusively used for the par­ticular type.
  • the object of the present invention is to provide a CRT socket structure which permits the common use of the focus connection contact in the soldering and snap-in types, thereby reducing the number of the kinds of the parts in making these different type CRT sockets.
  • a CRT socket comprises a housing, a focus connection contact and a focus spark-gap contact, these contacts along with other neces­sary contacts being built in the housing, said focus connection contact having a press contact terminal, and said focus spark-gap contact having a first terminal to be press-fitted in the press contact of said focus connection contact and a second terminal to be connected to a high-voltage lead conductor.
  • the second terminal of the focus spark-gap contact has an aperture to catch the stripped end of the high-voltage lead conductor for soldering the high-voltage lead conductor to the focus spark-gap contact.
  • the second terminal of the focus spark-gap contact has a folded catch end for permitting the press-contact of the high-voltage lead conductor in the focus spark-gap contact.
  • the focus connection contact can be commonly used in either type, soldering or snap-in type CRT socket.
  • Figs. 1(a), 1(b), 3, 4 and 5 show a CRT socket according to one aspect of the present invention in which a focus spark-gap contact is designed for soldering a high voltage lead conductor to the contact.
  • the CRT socket has a focus connection contact 21 and a focus spark-gap contact 22, which are built in a housing 25 along with other necessary con­tacts.
  • the focus connection contact 21 has a split tubulate ter­minal at one end and a press contact terminal 21c at the other end of the contact.
  • the press contact terminal 21c is formed by the inversed "U"-shaped end of the elongated contact strip in­tegrally connected to the split tubulate terminal at one end of the contact 21.
  • the inversed "U"-shaped end 21c has a slit 21d made at its bent portion.
  • the focus spark-gap contact 22 has a first, lateral terminal elongation 22d to be connected to the press contact terminal 21c of the focus connection contact 21 and a second, longitudinal terminal elongation 22e to be connected to a high voltage lead conductor 4 by soldering.
  • the second ter­minal elongation 22e has an aperture 22f to catch the core con­ductor end 4a of a high voltage lead conductor 4. As shown in Figs.
  • the focus connection contact 21 is connected to the focus spark-gap contact 22 by pushing the first terminal elongation 22d of the focus spark-gap contact 22 in the slit 21d of the inversed "U"-shaped end 21c of the focus connection con­tact 21, and the focus spark-gap contact 22 is connected to a high-voltage lead conductor 4 by inserting its core conductor and 4a in the aperture 22f of the first terminal elongation 22e of the focus spark-gap contact 22.
  • Figs. 6(a), 6(b), and 7 show a CRT socket according to another aspect of the present invention in which a focus spark-­gap contact is designed to permit press-contacting of a high voltage lead conductor to the contact.
  • the same reference numerals as used in Figs. 1 to 5, are used in Figs. 6 and 7 to indicated the same parts of the CRT socket.
  • the CRT socket uses the same focus connection contact 21 as used in the soldering type of Figs 3 to 5.
  • the focus spark-gap contact 32 has a first, lateral terminal elongation 32d to be connected to the press contact terminal 21c of the focus connection contact 21 and a second, longitudinal terminal elongation 32g to permit a high voltage lead conductor 4 to press-contact to the contact 32.
  • the second terminal elongation 32g has a stationary contact part 32g1 and a movable contact part 32g2. These parts are formed by bend­ing and folding the lateral projection of the second terminal elongation 32g, as best shown in Fig. 6. Thus, the movable con­tact part 32g2 pushes itself against the stationary contact part 32g1 resiliently.
  • the focus spark-gap contact 32 is connected to a high-voltage lead conductor 4 by pushing its core conductor end 4a between the stationary and movable contact parts 32g1 and 32g2.
  • the spark-gap electrodes are indi­cated at 22c and 32c.
  • the housing 35 is open upward at a place in which a spark electrode is contained.
  • the housing 35 has a press-fit closure 31 to close its opening.
  • the press-fit closure 31 has an aperture to allow the press contact elongation 32g of the focus spark-gap contact 32 to pass through.
  • the press-­fit closure 31 has a press-fit cap 37 hinged at 38 to the top of the press-fit closure 31 for closing the aperture of the press-­fit closure.
  • An upright enclosure 36 is fixed to the top of the press-fit closure body 33, and the stationary contact part 32g1 is held by the upright enclosure will to prevent the stationary contact part 32g1 from bending outwards.
  • the press-fit cap 37 has a push projection 30 integrally connected to its inside ceil­ing, and the movable contact part 32g2 is pushed against the sta­tionary contact part 32g1 by the push projection 30 of the press-­fit cap 37, thereby firmly holding the core conductor 4a of the high voltage lead conductor 4.
  • the press-fit cap 37 is closed with its front edge caught by a guide ridge 39 which is integrally connected to the top of the press-fit closure 31, the opposite side projections (not shown) of the press-fit closure body 33 will be put in engagement with the counter recesses of the press-fit cap 37, thus locking the press-fit cap 37.
  • a focus connection con­tact having a press-contact terminal can be mated with a focus spark-gap contact having a lateral extension by press-fitting the lateral extension of the focus spark-gap contact in the press-­contact terminal of the focus connection contact, whether the CRT socket is of the soldering type or of the snap-in type.
  • the use of such a compatible focus connection contact permits reduction of the number of the kinds of required parts by one in making CRT sockets.
