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.
