Description

GERMAN

The invention relates to connectors for electrical components and relates to training the foot end of such components. In particular, it is used in electron tubes.

If a radio intended for use at high altitudes is not pressure-tight, what is very costly exists as a result of the reduced atmospheric pressure at relatively low voltage has a tendency to develop spray discharge; this can affect the normal Have a very disruptive effect on the operation of the device.

With plug connections for components and especially for electron tubes it was found that such Spray discharges preferably at the base end of the components between the lead-in wires or pens are created.

Although it is already known, an insulating washer provided with holes over the miniature tubes To push the ends of the lead wires before they are bent over to make connections will. However, this known measure is not used to avoid particularly at great heights occurring spray discharges ,, but is intended to break off the wires just below their melting point prevent into the tube socket. It is known that the thin lead wires become brittle at the melting point due to the high temperatures. Since the well-known insulating washer in miniature tubes for the To provide wires with a mechanically strong hold, they must have a relatively high stiffness. Therefore can the disc material also does not have any protection against spray discharges that completely tightly encloses the individual wires Offer. It is true that this known arrangement is used to avoid spray discharges already provided, the remaining spaces with an easily deformable fabric of high Melting point, like silicone grease, to be filled in. The use of insulating greases for plug connections is associated with considerable disadvantages; because once is not guaranteed and also not it can be checked whether every spray connection is actually blocked and at the often relatively high temperatures and the vibrations to which such devices are subjected, also reliably prevented remain. In addition, it can not always be avoided that the grease also the pins with a thin insulating layer and impairs the contact closure.

The purpose of the invention is to create a plug connection for electrical components in order to avoid such spray discharges to avoid.

has been named as the inventor

Has wires or pins is according to the invention each insertion wire or pin from a ring of resilient, non-hygroscopic insulating material, such as natural or synthetic rubber, a synthetic silicone compound or a resilient plastic, and each ring is designed so that when the component is in its holder or cap is inserted, is compressed between them.

To enable compression, the rings are preferably curved in shape. Either individual rings may be disposed around each insertion wire or pin, or alternatively may A plate of insulating material also extends over the surface of the component foot, and the rings can be formed by protrusions protruding from this plate, the elevations being openings for the Have insertion wires or pins ..

Preferably the rings are made from a synthetic silicone compound. You can optionally also from natural or synthetic rubber or from a flexible plastic one Be material. It is important, however, that they are made of a non-hygroscopic material, i.e. H. that they cannot absorb moisture.

In the case of a tube in which the lower end of the tube casing is inserted into a socket from the Pins protrude for insertion into a socket, rings can be both between the tube casing and the base as well as between the base

and a version that supports it, so that spray discharge between the insertion wires or pins at all points outside the tubular envelope is avoided.

To hold the tube or other components in the socket, per se known flexible Tensioning means can be provided which ensure that the insulating rings are kept constantly under compressive stress and, moreover, that vibration does not loosen the pins in the socket holder.

An advantage of the device according to the invention is to be seen in the fact that the need for pressure-tight Manufacture of the devices is avoided.

The invention is explained in more detail using schematic drawings of two exemplary embodiments.

Fig. 1 is an external view of an electron tube embodying the invention;

FIG. 2 shows a modified embodiment in which the tube shown in FIG. 1 is inserted into a base is used, which in turn is connected to a socket. The tube is shown in external view, while the base and socket are shown in section; and

Figure 3 is a top plan view of the base shown in Figure 2 with the tube removed.

In Fig. 1, the reference numeral 1 designates the tube casing, while with 2 the pins for the direct insertion into a socket are designated. According to the invention are around the pins 2 rings 3 preferably made of synthetic silicone type rubber are arranged on the Place where they come out of the foot end of the tube casing 1. It can thus be seen that the rings 3 are compressed between the base of the tube and the surface of the socket when the tube is inserted into the socket and the deformation caused thereby effectively seals the open parts of the pins.

In the modified arrangement shown in FIG. 2, the tubular casing 1 is provided with a base 4, and the normal or shortened plug pins 2 are attached to contact pins 5 on the socket

are attached and are inserted into socket contacts 6 of a version 7. The tube pins 2 are again provided with rings 3. In a similar way, 4 rings 8 are arranged on the inner surface of the base, have the arched shape with a protruding part 9 which is against the ring 3 lays and can be compressed to thereby form a completely secure seal. Additionally Rings 10 are provided around the pins 5 at the point where they protrude from the surface of the base 4. The rings press against the surface 11 of the socket 7 and are thereby compressed. The tube base is also provided in a manner known per se with a pin 12 provided in the middle provided, which sits in a corresponding pin opening in the socket. Around the tube in the socket to hold, clamping means known per se can be provided.
