Opfindelsen angår et elektrisk værktøj såsom en boremaskine med et hus, en deri soitrbyggeelement løsbart anbragt stator og en ved huset løsbart anbragt håndtagsdel med elektriske byggeelementer og knivkontakter til etablering af en elek-5 trisk forbindelse med husets elektriske byggeelementer, hvorhos kontakterne mellem håndtagsdelen og byggeelementerne af huset ved fjernelse af håndtagsdelen automatisk brydes og ved fastgørelse af håndtagsdelen automatisk sluttes.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an electric tool such as a drill with a housing, a stator removably disposed therein and a handle member detachably disposed at the housing with electrical construction elements and knife contacts for establishing an electrical connection with the electrical construction elements of the housing, wherein the contacts between the handle element and the building element of the housing when removing the handle part is automatically broken and when fastening the handle part is automatically closed.
Fra U.S.A. patentskrift nr. 3.588.411 kendes en håndborema-10 skine med et hus og en løsbart monteret håndtagsdel med knivkontakter. Ved frigørelse af håndtagsdelen bliver kontakterne mellem håndtagsdelen og huset automatisk afbrudt. Statoren vil imidlertid kun kunne udskiftes med besvær.From usa. U.S. Patent No. 3,588,411 discloses a hand drill with a housing and a detachably mounted handle portion with knife contacts. When the handle part is released, the contacts between the handle part and the housing are automatically disconnected. However, the stator can only be replaced with difficulty.
Ifølge opfindelsen er statoren udstyret med kontakter, der 15 samvirker med knivkontakterne, og som ved fjernelse af statoren automatisk bryder den elektriske forbindelse mellem byggeelementerne og håndtagsdelen og ved indsætning af statoren automatisk slutter denne.According to the invention, the stator is provided with contacts which cooperate with the knife contacts and which, when removing the stator, automatically breaks the electrical connection between the building elements and the handle part and when inserting the stator it automatically terminates.
Derved lettes udskiftningen af statoren.This facilitates the replacement of the stator.
20 Opfindelsen skal nærmere forklares i det følgende under henvisning til tegningen, hvor fig. 1 viser et elektrisk værktøj ifølge opfindelsen, fig. 2, en del af det i fig. 1 viste værktøj i stort målforhold, og 25 fig. 3, den i fig. 2 viste del, set i snit efter linien III-III.The invention will be explained in more detail below with reference to the drawing, in which 1 shows an electrical tool according to the invention; FIG. 2, part of the embodiment of FIG. 1 in large scale, and FIG. 3, the one shown in FIG. 2 in section along line III-III.

Det i fig. 1 viste elektriske værktøj 1 har en håndtagsdel 2. Håndtagsdelen består af to i hovedsagen symmetriske halvdele, som er løsbart forbundet til hinanden. Værktøjet har desuden en holder 3 til et arbejdsorgan 4, såsom 5 et bor eller en mejsel. Håndtagsdelen 2 er ved hjælp af skruer 5, 6, 7 løsbart forbundet til værktøjets hus la - se fig. 3. I dette hus la er der endvidere et ikke vist gear og en elektromotor, hvoraf der i fig. 1 er vist en stator 9 med et isolerende hus 8 og en rotor 10.The FIG. 1 electrical tool 1 has a handle portion 2. The handle portion consists of two substantially symmetrical halves which are detachably connected to each other. In addition, the tool has a holder 3 for a working member 4, such as 5 a drill or a chisel. The handle part 2 is releasably connected to the housing of the tool by means of screws 5, 6, 7 - see fig. 3. In this housing 1a there is furthermore a gear not shown and an electric motor, of which in FIG. 1, a stator 9 is shown with an insulating housing 8 and a rotor 10.
10 I fig. 1 er der desuden vist nogle elektriske byggeelementer.10 In FIG. 1, some electrical building elements are also shown.
Byggeelementerne strømforsynes fra et kabel 11, som kan sluttes til lysnettet. Byggeelementerne omfatter en trykafbryder 12 og en kondensator 13. Til fiksering af de respektive forbindelsesledere har trykafbryderne 12 nogle kontaktskruer 12a.The building elements are powered from a cable 11, which can be connected to the mains. The building elements comprise a pressure switch 12 and a capacitor 13. For fixing the respective connection conductors, the pressure switch 12 has some contact screws 12a.
15 I håndtagsdelen kan der eventuelt anbringes flere byggeelementer alt efter bestemmelserne i det land, hvori værktøjet skal anvendes.15 In the handle part, several building elements may be placed according to the regulations of the country in which the tool is to be used.
De elektriske ledere, som er ført ud til grænsefladen mellem håndtagsdelen 2 og værktøjets hus la, er tilsluttet kontakt-20 elementer, som automatisk tilvejebringer en elektrisk forbindelse ved tilkobling af håndtagsdelen. I fig. 1 er ledere 14, 15, 16 fra kondensatoren 13 ført ud til bøjleformede kontaktelementer 17, 18, 19 - se fig. 3 - hvilke kontaktelementer på sin side er fastgjort til en holder 20, som f. eks. kan udgø-25 res af isolerende materiale. Til fastholdelse af holderen 20 er håndtagsdelen 2 forsynet med kulisser 2a, 2b, mellem hvilke holderen 20 kan forskydes, når håndtagsdelen 2 er i åben tilstand.The electrical conductors which are extended to the interface between the handle part 2 and the tool housing 1a are connected to contact elements which automatically provide an electrical connection when the handle part is connected. In FIG. 1, conductors 14, 15, 16 from capacitor 13 are output to shackle contact elements 17, 18, 19 - see FIG. 3 - which contact elements are in turn attached to a holder 20, which can, for example, be made of insulating material. For holding the holder 20, the handle part 2 is provided with backdrops 2a, 2b, between which the holder 20 can be displaced when the handle part 2 is open.
Modkontakterne til de bøjleformede kontaktelementer 17, 18, 19 30 udgøres af små pladeformede kontaktelementer 21, 22, 23, som fastholdes i statorens hus 8. Kontaktelementerne 21, 22, 23 er via ledere 24, 25, 26 sluttet til statorens 9 vikling.The counter contacts of the shackle contact elements 17, 18, 19 30 are constituted by small plate-shaped contact elements 21, 22, 23 which are held in the stator housing 8. The contact elements 21, 22, 23 are connected to the winding of the stator 9 via conductors 24, 25, 26.
