Description
Denne oppfinnelse angår en elektrisk kontakt-innretning. Fra US-patent 3 356 987 er det kjent en elektrisk kontakt-innretning som omfatter en elektrisk klemme med en kontaktende og en presshylse for tilkobling til en elektrisk leder, hvor presshylsen blir opptatt i en metallhylse som strekker seg utenfor enden av presshylsen i retning bort fra kontaktenden av klemmen, hvilken metallhylse på sin side blir opptatt i.en ytre hylse av elektrisk isolerende materiale. This invention relates to an electrical contact device. From US patent 3 356 987 an electrical contact device is known which comprises an electrical clamp with a contact end and a press sleeve for connection to an electrical conductor, where the press sleeve is taken up in a metal sleeve which extends beyond the end of the press sleeve in the away direction from the contact end of the clamp, which metal sleeve is in turn absorbed in an outer sleeve of electrically insulating material.
For bruk av en slik kontaktinnretning blir et avisolert endeparti av lederen i en isolert elektrisk ledning innsatt i presshylsen på klemmen gjennom metallhylsen, med et isolert parti av lederen plassert i det parti av metallhylsen som strekker seg utenfor presshylsen. For the use of such a contact device, a stripped end portion of the conductor of an insulated electric wire is inserted into the crimp sleeve of the clamp through the metal sleeve, with an insulated portion of the conductor placed in the portion of the metal sleeve that extends beyond the crimp sleeve.
Presshylsen blir så presset fast på lederen gjennom den overliggende ytre isolerende hylse og metallhylsen, som begge derved blir permanent deformert ved pressingen, og det parti av metallhylsen som strekker seg utenfor presshylsen, blir presset omkring lederens isolasjon gjennom den overliggende ytre isolerende hylse som også blir permanent deformert ved denne pressing. The pressing sleeve is then pressed firmly onto the conductor through the overlying outer insulating sleeve and the metal sleeve, both of which are thereby permanently deformed by the pressing, and the part of the metal sleeve that extends outside the pressing sleeve is pressed around the conductor's insulation through the overlying outer insulating sleeve which also becomes permanently deformed by this pressing.
En slik elektrisk kontaktinnretning har fordeler ved at klemmen kan fremstilles av materiale som er forholdsvis tynt slik at de nødvendige fjæringsegenskaper sikres i dens kontaktende, mens metallhylsen tjener til å øke tykkelsen av metall ved presshylsen for derved å sikre pålitelig fastpressing av klemmen på lederen. Such an electrical contact device has advantages in that the clamp can be made of material that is relatively thin so that the necessary spring properties are ensured at its contact end, while the metal sleeve serves to increase the thickness of metal at the pressing sleeve to thereby ensure reliable pressing of the clamp onto the conductor.
Det oppstår imidlertid fremdeles vanskeligheter med slike kontaktinnretninger fordi hvis metallhylsen gjøres tilstrekke-lig tykk til .å sikre tilfredsstillende pressing av presshylsen, er den ofte for tykk til at en tilfredsstillende pressing av de. partier av denne som ligger over lederisolasjonen, kan ut-føres på lett og bekvem måte. However, difficulties still arise with such contact devices because if the metal sleeve is made sufficiently thick to ensure satisfactory pressing of the pressing sleeve, it is often too thick for satisfactory pressing of them. parts of this that lie above the conductor insulation can be carried out in an easy and convenient way.
Det er kjent lignende kontaktinnretninger ved hvilke metallhylsen er tildannet av metallplate og har en langsgående åpen søm, idet det tykkveggede parti av metallhylsen er dannet ved å folde et parti av metallplaten tilbake mot seg selv. Similar contact devices are known in which the metal sleeve is made of sheet metal and has a longitudinal open seam, the thick-walled part of the metal sleeve being formed by folding a section of the metal sheet back towards itself.
Det er imidlertid vanskelig å fremstille slike kjente kontaktinnretninger, og de er ikke alltid pålitelige under bruk fordi metallhylsen - i betraktning av den åpne søm, er utsatt However, it is difficult to produce such known contact devices, and they are not always reliable in use because the metal sleeve - in view of the open seam, is exposed
for å avslappes. to relax.
Videre skal det nevnes at tidligere kjent teknikk av interesse også fremgår av US-patent 2 958 723 og 3 521 224. Furthermore, it should be mentioned that prior art of interest also appears in US patents 2,958,723 and 3,521,224.
Det sistnevnte US-patent beskriver en metallpresshylse som er plassert innenfor en ytre isolerende hylse som ved sin frie ende har en isolerende plugg i aksiell avstand fra presshylsen. Det finnes imidlertid ingen mellomhylse av metall slik som i det foran nevnte US-patent 3 521 224. The latter US patent describes a metal press sleeve which is placed within an outer insulating sleeve which at its free end has an insulating plug at an axial distance from the press sleeve. However, there is no intermediate sleeve made of metal as in the aforementioned US patent 3,521,224.
Nærmere angivelse av den elektriske kontaktinnretning ifølge oppfinnelsen samt de nye og særegne trekk ved denne er opptatt i patentkravene. A more detailed description of the electrical contact device according to the invention as well as the new and distinctive features thereof are included in the patent claims.
Et eksempel på en elektrisk kontaktinnretning ifølge denne oppfinnelse skal i det følgende beskrives nærmere under henvis-ning til tegningene, hvor: Figur 1 er et sideriss, delvis i snitt, gjennom en metallhylse i kontaktinnretningen, An example of an electrical contact device according to this invention will be described in more detail below with reference to the drawings, where: Figure 1 is a side view, partially in section, through a metal sleeve in the contact device,
figur 2 er et snitt gjennom hylsen på figur 1 opptatt i Figure 2 is a section through the sleeve of Figure 1 taken up in
en ytre isolasjons-hylse på kontaktinnretningen, og an outer insulating sleeve on the contact device, and
figur 3 er et planriss av den komplette kontaktinnretning. figure 3 is a plan view of the complete contact device.
På figure 1 er det vist en sømløs metallhylse 1 med sirku-lært tverrsnitt samt med et parti 2 som har forholdsvis tykk vegg og et parti 3 som har forholdsvis tynn vegg. En slik metallhylse kan fremstilles med konvensjonell metallbearbeidings-teknikk. Figure 1 shows a seamless metal sleeve 1 with a circular cross-section and with a part 2 which has a relatively thick wall and a part 3 which has a relatively thin wall. Such a metal sleeve can be produced with conventional metalworking techniques.
Mellom partiene 2 bg 3 er det tildannet et mellomparti 4 som utgjør et traktformet innløp 5 fra partiet 3 inn i partiet 2. Mellompartiet '4 danner også en skulder 6 som vender mot partiet 2. Between the parts 2 bg 3, an intermediate part 4 is formed which constitutes a funnel-shaped inlet 5 from the part 3 into the part 2. The intermediate part '4 also forms a shoulder 6 which faces the part 2.
Den frie ende 7 av partiet 3 er utvidet eller konisk i retning utad for å danne et traktformet innløp. The free end 7 of the portion 3 is widened or conical in the outward direction to form a funnel-shaped inlet.
På figur 2 er det vist hvordan metallhylsen 1 er opptatt Figure 2 shows how the metal sleeve 1 is occupied
i en ytre hylse 8 av elektrisk isolerende plastmateriale, hvilken ytre hylse 8 strekker seg'utenfor den frie ende 7 av partiet 3 av hylsen 1. in an outer sleeve 8 of electrically insulating plastic material, which outer sleeve 8 extends beyond the free end 7 of the part 3 of the sleeve 1.
Figur 3 viser den komplette kontaktinnretning som' omfatter en elektrisk klemme 9 med en kontakt-sokkel 'eller kontaktende 10 for samvirke med en flat stift (ikke vist) og en presshylse 11 av kjent form for tilkobling til en elektrisk leder. Presshylsen 11 blir opptatt i partiet 2 av metallhylsen 1- idet Figure 3 shows the complete contact device which comprises an electrical clamp 9 with a contact socket or contact end 10 for cooperation with a flat pin (not shown) and a press sleeve 11 of known form for connection to an electrical conductor. The pressing sleeve 11 is taken up in the part 2 of the metal sleeve 1
innføringen i denne er begrenset av skulderen 6. the introduction into this is limited by the shoulder 6.
For bruk av kontaktinnretningen blir isolasjonen 12 fjer-net fra et parti ved enden av en isolert elektrisk.leder 13, For use of the contact device, the insulation 12 is removed from a portion at the end of an insulated electrical conductor 13,
og endepartiet blir -,så innført i den frie ende av den ytre hylse 8 med enden av lederen 13 styrt inn i presshylsen 11 av. det traktformede innløp 5 i metallhylsen 1, hvilket innløp 5 også tjener til å begrense innføringen av lederen ved å komme i anlegg mot isolasjonen 12 på lederen med innløpet 5. Presshylsen 11 blir så presset mot lederen 13 gjennom den ytre hylse 8 og partiet 2 på metallhylsen 1, og partiet 3 på metallhylsen 1 kan presses inn mot isolasjonen 12 på lederen gjennom den ytre hylse 8 på i og for seg kjent måte. and the end portion is then introduced into the free end of the outer sleeve 8 with the end of the conductor 13 guided into the pressing sleeve 11 by. the funnel-shaped inlet 5 in the metal sleeve 1, which inlet 5 also serves to limit the introduction of the conductor by coming into contact with the insulation 12 of the conductor with the inlet 5. The pressing sleeve 11 is then pressed against the conductor 13 through the outer sleeve 8 and the part 2 on the metal sleeve 1, and the part 3 of the metal sleeve 1 can be pressed against the insulation 12 of the conductor through the outer sleeve 8 in a manner known per se.
Den forholdsvis store veggtykkelse i partiet 2 av metallhylsen 1 sikrer pålitelig fastpressing av kontaktinnretningen 1 på lederen 13 selv når materialet i klemmen 9 er forholdsvis tynt slik det kan være påkrevet for å sikre de nødvendige fjæringsegenskaper i kontakt-t eller sokkelenden 10 av denne, mens den forholdsvis tynne vegg i partiet 3 av metallhylsen 1 mulig-gjør lett fastpressing av dette parti på isolasjonen 12 på lederen. Videre vil fravær av en søm i metallhylsen 1 sikre at denne ikke avslappes etter pressingen, hvilket kunne skje hvis metallhylsen 1 hadde en langsgående åpen søm slik det forekom-mer i mange kjente kontaktinnretninger. The relatively large wall thickness in the part 2 of the metal sleeve 1 ensures reliable pressing of the contact device 1 on the conductor 13 even when the material in the clamp 9 is relatively thin as may be required to ensure the necessary spring properties in the contact t or the socket end 10 thereof, while the relatively thin wall in part 3 of the metal sleeve 1 enables easy pressing of this part onto the insulation 12 of the conductor. Furthermore, the absence of a seam in the metal sleeve 1 will ensure that it does not relax after pressing, which could happen if the metal sleeve 1 had a longitudinal open seam as occurs in many known contact devices.
