"Intermediate body for fastening line insulators ¹¹

For the fastening of overhead lines, insulators made of ceramic materials are usually used for their part again attached to the carrier hook by means of an insulating and elastic medium · In recent times is one went over to using intermediate bodies made of plastics, which in specially built forms on the The end of the carrier hook prepared for this purpose can be sprayed on in one or two separate operations · As special Plastics such as polyethylene or nylon have proven suitable for this purpose.

The disadvantages inherent in this method lie Clearly obvious · The production in one-piece molds is practically not feasible because of the high pressures involved in the injection molding process always cause a strong deformation of centrally located, single-stringed metal parts, which should only be encased by injection molding compounds · The

Manufacture in two separate molds, where each mold has its own only half of the intermediate body is produced, is absolutely reliable in terms of shape and hold, but requires a much higher expenditure of costs, material and working time «

The innovation now aims to create an intermediate body that is manufactured independently of the carrier hook can be and due to its properties without further aids by simply pressing on the carrier hook can be securely attached. The innovation is essentially that on the inside of the one-sided open Hollow body one or more pairs of symmetrically distributed, diametrically opposite ribs run helically with the same or different pitch.

In Fig.1 the intermediate body is shown in view and in Fig.2 in cross section. The outside of the intermediate body is, as Fig »1 shows, provided with a sharp thread, the pitch of which is that of the round thread in the Inside the isolator. The peak height is however larger by a certain amount. When unscrewing of the insulator on the intermediate body, the thread tip of the intermediate body is so strongly squeezed that not only the cavities of the round thread are filled, but also the desired reliable press fit is achieved will.

On the inside there are one or more pairs of fine ribs 1, 2, 3 and 1 ^T , 2 », J 'in the form of helical lines, with the screw connection of two B

To simplify the illustration, the slope of the rib is assumed to be the same, but if necessary it can be changed so that in each pair one type of rib has an infinitely large and the other an infinitely small slope, so that a network of orthogonally intersecting Ribs results. Due to the intended, customary roughening of the hook end, the ribs 1, 2, 3 and 1 », 2f, 3r are completely squeezed when pressed onto the same and also provide the desired, secure press fit here. An additional increase in this pressure occurs when the insulator is screwed onto the intermediate body.In order to ensure the correct position of the intermediate body on the carrier hook, the cavity 6 of the intermediate body is closed off at the top by the wall 4, which is a certain amount lower than the upper end of the intermediate body. The resulting free space is intended to accommodate the edge deformed by unscrewing the insulator and to create a kind of stress compensation. Furthermore, to avoid overvoltages in the insulator, the lower edge of the intermediate body can have one or more axially parallel or inclined slots of a certain length.
