The present invention relates to a connector composed of support means made of an insulating material which ensures electrical connection between various parts of a cathode ray tube and a printed circuit and annularly surrounds contact means for various connections.

Electrical means in contact with the base of the cathode ray tube are protected inside the connector, while not in the case of the contact outlet to be connected to the printed circuit. These contact outlets are on the outside of the connector if they penetrate the precision holes provided in the printed circuit.

As is known, these contact means consist of brittle conductors. It is therefore inevitable to carefully protect the connectors when they are packed and until they are inserted into the printed circuit to avoid messing up their shape during storage and transport.

In order to avoid anticipated breakage, certain types of packing are currently in use but in the end this leads to an increase in cost. Even in this case, it is difficult to conclude that the desired protection has been sufficiently achieved.

The present invention eliminates many of the deficiencies described above by the inventive arrangement of the various components of the connector. They are then packaged without requiring any special precautions to be taken during storage and transport, while at the same time optimal positioning on the printed circuit can be obtained by hand or by machine.

In the present invention, the connector is made of two parts of insulating material. One part is a connection holder casing, and the other part forms a base plate of the same shape as the casing.

The baseplate includes the same number of housings as the contact outlets. The baseplate serves to protect and guide the contact outlets inserted into the housing of the baseplate.

The baseplate and the contact holder casing form a connector and can be joined by sliding the two parts together. When inserted into the printed circuit, the contact outlets protrude to predetermined lengths through the respective housings in the base plate.

This result is obtained by the interaction of the guide means, the support and locking means in the casing with the printed circuit hole.

Advantages and characteristics of the present invention include the average voltage connection between the cathode ray tube and the corresponding printed circuit, as well as the first, second and third views of partial views of embodiments of the connector according to the present invention at different positions relative to the printed circuit. It will be more clearly understood with reference to FIG. 4, which shows a perspective view of the finished cathode wire and connector to ensure a high voltage connection.

Reference figures 1 in FIGS. 1, 2 and 3 are casings with an appropriate number of electrical contacts. One of the electrical contacts is shown by reference numeral 2. Of course, these electrical contacts can be provided with conventional sparkgaps of a type well known to users. The spark gap is not included in the ball invention. The baseplate is indicated by the reference number 3. The printed circuit is indicated by the reference numeral 4.

One of the support and locking means corresponding to the connector is shown in three different positions on three figures. On the other hand, the means comprises an elastic strip 5 of insulating material, for example plastic. One end of the strip is integrally connected with the casing 1. The other end which becomes the free end forms the inclined surface 6. The strip 5 has a stop member 7 and a shoulder 8 formed behind the inclined surface 6. The means also includes a wife housing 9 integral with the baseplate 3 such that portions 10, 10 protrude inwards and the strip can slide.

Two or preferably three support and locking means can be arranged in the same way on the outer circumferential surface of the connector as just described. The support and locking means may be of a different shape than the given example.

1 is a partial side view of the connector 1-3 at the last stage of manufacture ready for storage, transfer and handling. This figure is shown in connection with the corresponding printed circuit 4 to be connected. In this position, the contact outlet 12 is inserted into the hole 11 of the electrical contact protective housing 11 on the base plate 3. The casing 1 is locked and elastically supported along the shoulder 8 of the strip 5 by the protrusion 10 while the base plate 3 is attached to the protrusion 10 of the housing 9 which is integral with the base plate. Is fixed by.

In the second, the pressure applied perpendicularly to the casing reacts to the printed circuit 4 and moves the strip 5 laterally by the inclined surface 6 to the rim hole 14 in the printed circuit 4. This movement, in turn, moves the stop member 7 of the strip 5 laterally away from the projection 10 inside the housing 9 which is integral with the base plate 3. In this state, the base plate 3 is completely free to translate vertically to the printed circuit 4 in the casing 1 direction.

FIG. 3 shows the final step of applying the total pressure on the casing perpendicular to the printed circuit 4 to position and fix the connector on the printed circuit 4 and at the same time confirm the support and locking operation of the strip. On the other hand, the base plate 3 which is in contact with the printed circuit 4 is translated in the casing direction perpendicular to the printed circuit, and the contact outlet 12 passes through the hole of the base plate 3. The contact outlet then penetrates through the hole 13 of the printed circuit and protrudes onto the printed surface on the welding side and is soldered in a conventional manner and attached to the printed circuit.

It can be seen from the above description that the protection conditions required for the contact outlet 12 are fully implemented until the last minute in a simple and efficient manner.

4 is a perspective view of a finished connector consistent with the present invention. This connector ensures medium and high voltage connections in the G3 printed circuit range. The reference numerals in FIG. 4 are the same as the reference numerals in FIGS. It can be seen that not only the casing 1 but also the baseplate 3, the elastic strip 5, and the housing 9 integral with the baseplate are shown.

Reference numeral 15 is a passage of a cathode ray tube pin formed in the casing and a hole 16 is a passage for a high voltage connection cable in the G3 printed circuit range.

Of course, variations in the number or form and location of the guide assemblies or components used for support and locking purposes do not depart from the scope of the invention.

In particular, the present invention is applied to a connector which secures a connection between a portion of a cathode ray tube and a printed circuit as described above. Nevertheless, it can also be used for other connectors where efficient protection of the contact outlet is required.

Finally, in order to ensure the protection of the contact outlets during storage, transport and handling as described above, the present invention is suitable for direct contact and selection of connectors into printed circuits by means of handling equipment attached to the automatic mounting assembly line for components. The distribution and safe handling of the shaped connector can be envisioned.
