Description
Päällystettyjen ilmajohtojen liitinCoated overhead line connector
Keksinnön kohteena on päällystettyjen ilmajohtojen liitin, johon kuuluu kaksi runko-osaa, ylempi runko-osa ja alempi runko-osa, kontaktihampaat kum-5 massakin runko-osassa, kiristysruuvi runko-osien ja niiden kontaktihampai-den siirtämiseksi toisiaan kohti ja murtokohdalla varustettu momentinsiirto-mutteri, joka on sisäkierteellään tartunnassa kiristysruuvin ulkokierteeseen ylemmän runko-osan yläpuolella.The invention relates to a connector for coated overhead lines comprising two frame members, an upper frame member and a lower frame member, contact teeth on each of the frame members, a clamping screw for displacing the frame members and their contact teeth to one another, and a torque point a nut that engages with the inner thread above the upper body of the clamping screw.
10 Tällainen liitin tunnetaan hakijan patenttijulkaisusta FI-102120. Tässä ja muissa vastaavissa liittimissä on ongelmana liittimen käsittelyyn liittyvät hankaluudet asennuksen yhteydessä. Liittimen ulkopinta on liukas varsinkin sateella ja talvella, jolloin liittimestä on vaikea saada pitävää otetta, jotta johti-met saadaan paikalleen liittimeen.Such a connector is known from Applicant's Patent Publication FI-102120. This and other similar connectors have a problem with the connector handling difficulties during installation. The outer surface of the connector is slippery, especially in rain and winter, where it is difficult to get a firm grip on the connector to insert the wires into the connector.

Keksinnön tarkoituksena on saada aikaan alussa mainittua tyyppiä oleva liitin, jossa edellä mainittua käsittelyyn liittyvää ongelmaa on helpotettu.It is an object of the invention to provide a connector of the type mentioned at the outset, in which the above handling problem is alleviated.
Tämä tarkoitus saavutetaan keksinnöllä oheisessa patenttivaatimuksessa 1 20 esitettyjen tunnusmerkkien perusteella. Kun kontakti ha m päiden vesitiivis kiinnityselastomeeri ulottuu runko-osien ulkosivuille, se lisää tartunta kitkaa ja liittimestä saadaan parempi ote. Erillisiä tartuntakitkaa lisääviä elementtejä ei tarvitse tehdä vaan kontakti ha m päiden kiinnityselastomeeri toimii kahdessa 0 tehtävässä.This object is achieved by the invention on the basis of the features set forth in the appended claim 1 20. When the waterproof contact elastomer of the contact ends extends to the outside of the body members, it increases adhesion friction and provides a better grip on the connector. There is no need to make separate adhesion-enhancing elements, but the contact elastic bonding elastomer functions in two 0 functions.

Kuvio 1 esittää keksinnön mukaisen liittimen pystyleikkausta kohtisuorassa suunnassa liitettäviin johtimiin nähden;Fig. 1 is a vertical sectional view of a connector according to the invention, perpendicular to the conductors to be connected;
Kuvio 2 esittää saman liittimen pystyleikkausta liitettävien johtimien suun-5 nassa jaFigure 2 shows a vertical section through the same connector in the direction of the conductors to be connected and
Kuvio 3 esittää samaa liitintä päätysivulta nähtynä liitettävien johtimien suunnassa katsottuna.Figure 3 shows the same connector as seen from the end side, in the direction of the conductors to be connected.
10 Esitettyyn liittimeen kuuluu kaksi runko-osaa, nimittäin ylempi runko-osa 1 ja alempi runko-osa 2. Kummassakin runko-osassa on kontakti hampaat 3, jotka tukeutuvat runko-osien kovaa muovia olevaan materiaaliin. Kontaktihampaita 3 ympäröi pehmyt muovi, erityisesti elastomeeri 8, jolla kontaktihampaat on vesitiiviisti kiinnitetty runko-osiin. Nämä edullisesti elastomeeria olevat peh-15 mytmuoviosat 8 ulottuvat runko-osien ulkosivuille, jolloin käsittelyä helpottava tartuntakitka lisääntyy. Nämä pehmytmuoviosat 8 on jo lähtökohtaisesti, eli ennen liittimen kiinnitystä johtimeen, muotoiltu ulottumaan runko-osien 1, 2 ulkosivupinnoille tartuntakitkan lisäämiseksi. Elastomeeri 8 on väriltään runko-osien 1 ja 2 väristä olennaisesti poikkeavaa ja myös mustasta olennai-20 sesti poikkeavaa, esimerkiksi sinistä tai vaalean harmaata. Värivalintoja voidaan käyttää myös erilaisiin liitintyyppien koodaustarkoituksiin. Elastomeeri 8 on varustettu riittävällä UV-suojalla. Elastomeerin aiheuttama tartunta-apu ja poikkeava väritys helpottavat asennusta.10 The connector shown comprises two body members, namely an upper body member 1 and a lower body member 2. Each body member has contact teeth 3 which are supported by a material of hard plastic material of the body members. The contact teeth 3 are surrounded by a soft plastic material, in particular an elastomer 8, by means of which the contact teeth are watertightly attached to the body members. These preferably elastomeric soft plastic parts 8 extend to the outer sides of the body parts, thereby increasing the friction friction for ease of handling. These soft plastic parts 8 are already, by definition, prior to attaching the connector to the conductor, designed to extend to the outer side surfaces of the body parts 1, 2 to increase the frictional adhesion. Elastomer 8 is substantially different in color from body parts 1 and 2 and also substantially different in color from black, for example blue or light gray. Color choices can also be used for various coding purposes for connector types. Elastomer 8 is provided with adequate UV protection. Elastomeric adhesion aids and abnormal coloring make installation easier.

Kun riittävä kiristysvoima on saavutettu johtimien o liittämiseksi, mutteri 5 katkeaa murtokohdasta 6. Mutterin 5 paikalleen jäävä oö g 30 alempi osa voidaan tarvittaessa kiertää irti liittimen avaamiseksi, kun suoja- o holkki 13 on ensin poistettu mutterin 5 alaosan päältä. Mutterin 5 ja runko- 3 osan 1 välissä voi olla sopiva tukilevy, joka sallii ylemmän runko-osan 1 kallistelun suhteessa kiristysruuviin 4.> - 5 is engaged by its internal thread to the outer thread of the clamping screw 4 | above frame 1. When sufficient clamping force has been achieved to connect the conductors, the nut 5 breaks at the point of breaking 6. The lower portion of the nut 30 remaining in place may be unscrewed if necessary to open the connector after the protective sleeve 13 is first removed from the lower portion of the nut 5. A suitable support plate may be provided between the nut 5 and the frame 3 portion 1 to allow the upper frame portion 1 to tilt relative to the clamping screw 4.
Alemmassa runko-osassa 2 on siihen kiinni valettuna sisäkierteellä varustettu 5 torni 7, joka tarttuu kiristysruuvin 4 ulkokierteeseen. Tartuntamatka ulottuu olennaisen matkan alemman runko-osan 2 kontaktihampaiden 3 yläpuolelle. Tämä tornin 7 avulla lisätty tartuntamatka on suurempi kuin kiristysruuvin 4 halkaisija, edullisesti suurempi kuin liittimellä liitettävän johdon halkaisija, jolloin torni 7 ulottuu vähintään ylemmän runko-osan 1 kontaktihampaiden 3 10 tasolle, kun johdot on liittimellä liitetty. Edullisesti tornin 7 yläpää ulottuu käytössä ylemmän runko-osan 1 ohjaukseen, mikä tukevoittaa rakennetta. Tornin 7 ansiosta kiristyskuorma jakautuu alemmassa runko-osassa 2 pitkälle kierrematkalle, jolloin runkoon kohdistuva jännitys saadaan isommalle alueelle koko runkoon, eikä kontaktihampaiden 3 alapuolella jouduta alarungon 2 15 liialliseen mitoitukseen. Tämän seurauksena voidaan haluttaessa jättää kiristysruuvin 4 kanta 11 kokonaan pois, jolloin saavutetaan kustannussäästöä ja/tai kannaton kiristysruuvi voidaan tehdä paremmasta ja kalliimmasta materiaalista kuten ruostumattomasta teräksestä. Käytettäessä alarungon 2 alapuolella hahloavaimen tartuntamuotoilua 12, saadaan kierretartuntaa edel-20 leen pidennetyksi. Kierrereikä voi päättyä tartuntamuotoilun 12 sisään niin, että sen alapinta on umpinainen.The lower frame part 2 has a tower 7 with an internal thread molding thereon, which engages the outer thread of the clamping screw 4. The engagement distance extends substantially above the contact teeth 3 of the lower body portion 2. This gripping distance added by the tower 7 is larger than the diameter of the clamping screw 4, preferably larger than the diameter of the cable to be connected by the connector, whereby the tower 7 extends at least to the level of the contact teeth 3 10 of the upper frame part 1 when the cables are connected. Preferably, the upper end of the tower 7, in use, extends to the guide of the upper frame part 1, which strengthens the structure. Thanks to the tower 7, the tensioning load is distributed over the longitudinal thread in the lower frame part 2, whereby the tension on the frame is extended to a larger area throughout the frame, without under-dimensioning the lower frame 2 below the contact teeth 3. As a result, if desired, the head 11 of the clamping screw 4 can be completely omitted, whereby cost savings can be achieved and / or the unprofitable clamping screw can be made of a better and more expensive material such as stainless steel. By using the slot key gripping design 12 below the lower body 2, the thread engagement is further extended. The threaded hole may end within the gripping mold 12 so that its underside is closed.
