Elektrodenansc Pla for high-voltage clamping -

- rectifier . H, 21,

The price increase relates particularly to electrode connections for 3-light judges, which are rod-shaped E.g. for! TV sets with high .voltage.

Rectifiers of this type, mostly with at both ends Xcontact caps are provided, especially for high voltages of about 2o.coo volts, are well suited to replace the rectifier tubes previously used.

The installation of this atabiform rectifier for such high Voltage brings with it problems, primarily with the risk of spray discharges at the electrode connections 'are connected, so that arrangements of the known type for rod-shaped rectifiers have not yet provided sufficient security could ^ ·

The innovation also has the goal of a particularly safe and compact design and execution of the connecting parts for To enable rod-shaped rectifier, at the same time in particular also the risk of spray discharge due to a novel Training of the parts is to be counteracted.

The electrode connections for high-voltage rectifiers according to the innovation, especially for rod-shaped rectifiers, are primarily characterized in that the connection parts (3) inserted in cup-like insulating caps (1) Are tubular so that they cause an enclosure of the ends of the rectifier rod in addition to the contact.

In a preferred embodiment, the contact-making connection parts are designed as metallic sleeves (3-4), e.g. Sheet metal sleeves, formed, which have inwardly reaching contact ribs (a).

The tubular connecting parts (3) iron a further one ! '. feature according to local deformations, e.g. a bead or indentations, on, which are used to attach the connector (3) in the associated insulating housing (insulating cap 1).

.'Die essentially cup-like insulating caps (1) are designed in an advantageous embodiment so that, in addition to the connecting part (3), the connecting line (od, cable 7) is embedded _{on the or in the itantel of the insulating cap (l r 6)} .

The execution can advantageously take place according to the exemplary embodiment, with further features also based on the innovation the figures are explained,

Pig »1 and Fig.la show the lower electrode connection as a cross-sectional drawing from the side and (la) as a top view.

Fig. 2 shows the upper connection,

Fig. 3 shows an embodiment with a cover as a section. The contact sleeve 3 is at the bottom of the cup-like housing, which is designed as an insulating cap 1, is used, with a bead serving as a fastening means Instead of the continuous bead, local indentations can be provided, which approaches in the jacket of the insulating cap 1 opposite.

The inwardly reaching contact ribs (a) on the dumbbell of the contact sleeve 3 can, for example, at three or four places of the jacket, be produced by embossing, so that in the

Cooperation with the sheet metal sleeve 3 is a resilient concern with secure contact on the uncapping of the rectifier rod is achieved.

The contact sleeve 3 ″ also causes an almost complete enclosure the end caps and the rod ends, which counteracts the risk of spray discharge in the area of the connections.

Anate parts of the contact ribs (a) can contact means of a similar type, such as contact tongues, contact springs and contact inserts come into use.

Vie from the figure Fi3. 1 you will see the connection cable 7 connected to the contact sleeve 3 e.g. by soldering, where the soldering can be carried out before inserting the sleeve into the insulating cap. The connection cable 7 is in a special cable guide that is embedded in the jacket of the insulating cap (6), particularly protected. At tight Embedding is also a protection against twisting and a Strain relief achieved.

Fig. La shows the insulating cap 1 as a top view, in which the insulated cable guide (6) as Lantel of the cap, the advantageous has a connection ^ slot inwardly shown is.

Pig »2 shows the somewhat smaller insulating cap 2 for the upper connection, the contact sleeve 4 is inserted in the same // iron » At the upper end of the cable entry (od. Ilippel 5) is arranged, so that a relief of the upper solder point of the Connection cable 8 is achieved with tight guidance in the channel.

The attachment of the lower connection tab 11 can e.g. be carried out on the transformer, whereby other forms of the bracket (e.g. as a sliding mandrel) are also possible »

In another version according to the innovation ! Fig. 3, the insulating cap has a lower cover 10, which is e.g. fastened to the edge of the jacket by means of a clamp fastener is.

In this version, the end of the cable with the soldering point is accessible from the outside.

With an extremely compact shape of the electrode connections according to the innovation, the execution has important economic and technical advantages. Apart from the two contact sleeves, no further shielding parts are required, so that the protection against spraying is essentially due to the advantageous design of the contact parts.
