Definitions

  • the invention relates to an incandescent lamp socket with a touch-safe voltage supply, which socket has a center contact and a side contact, which can be moved relative to one another by screwing in an incandescent lamp, and a switch contact arrangement which is held in the open position by spring force when the incandescent lamp is unscrewed and relative to one another when the incandescent lamp is screwed in is movable and can be brought into a closed position.
  • a light bulb screw socket which has a socket held in the socket housing and a threaded basket that can be moved relative to the socket by screwing in the light bulb.
  • the foot contact and an intermediate contact, to which a wire of the supply line can be attached, is attached to the socket.
  • An insulating plate with a contact bridge is attached to the threaded basket, so that the contact bridge can be brought into contact with the foot contact and the intermediate contact in order to close the current path.
  • CH-A-248108 describes an incandescent lamp socket equipped with a touch protection, which has a fixed foot contact and a movable contact part which is guided over an insulating piece on the foot contact.
  • an incandescent lamp holder in which a plate with contact pieces, which can be moved by screwing an incandescent lamp in the direction of the socket, is used to produce the electrical connection for the threaded basket and the foot contact.
  • US-A-2306741 describes an incandescent lamp socket in which the foot contact is displaced when an incandescent lamp is screwed in.
  • the foot contact is designed on the one hand as a movable contact part and on the other hand is provided with a insulating piece in order to establish the electrical connection to the threaded basket.
  • incandescent lamp sockets have the common disadvantage that their switching contact arrangement has only one isolating distance and the contact is made only by a switching movement.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating an incandescent lamp socket in which each contact arrangement has two isolating paths and in which the contact between the connection terminals and the side contact or the center contact is effected by two separate switching movements.
  • a lamp holder with Edison thread which essentially has an upper part 1, a threaded basket 2, which forms the side contact 6, a lower part 3 and a body 5 with a center contact 7, which is clamped between the upper and lower part .

  • the intermediate contact part 36 is strip-shaped.
  • a contact nipple 41, 42 is provided in each of the end sections and protrudes from one side of the strip.
  • the intermediate contact part 36 is attached with the other side to the base surface of the recess 40 by a pin 43 such that the end section provided with the contact nipple 41 forms a movable section which can be pivoted by an external force to the contact nipple 41, 38 of the To bring intermediate contact part 36 and the fixed contact part 35 into contact with each other.
  • a bore 44 is provided, into which an actuating part 45 projects for pivoting the end section.
  • the other end section with the contact nipple 42 forms a fixed section due to the position of the attachment point of the intermediate contact part 36.
  • the movable contact part 37 is also strip-shaped.
  • a contact nipple 46 is arranged on the movable contact part 37 at one end and a holding rod 47 is fastened at one end at the other end.
  • the holding rod 47 is axially displaceably arranged in a hole 48 in the body 5 such that the contact nipples 42, 46 of the intermediate contact part 36 and the movable contact part 37 can be brought into contact with one another.
  • a further hole 49 is provided in the body 5, in which a second holding rod 50 is arranged to be axially displaceable.
  • Analogous to the first one Holding rod 47 has an actuating part 51 attached to one end of second holding rod 50.
  • a ring 54 is fastened to the other ends of the holding rods 47 and 50.
  • the ring 54 consists of a wire with a round cross section and has an inner diameter which is slightly larger than the core diameter of the thread on the lamp base.
  • the ring 54 is designed and fastened to the holding rods 47 and 50 in such a way that it forms a left-hand thread that can be brought into engagement with the thread on the lamp base.
  • the threaded basket 2 can also be fastened to the holding rods 47, 50.
  • the center contact 7 also has a fixed contact part 55, an intermediate contact part 56 and a movable contact part 57.
  • the fixed contact part 55 is fastened to the body 5 in a manner analogous to the side contact 6 by a part (not shown) designed as a fastening and connecting element, so that it projects into the recess 40 and is provided with a contact nipple 58.
  • the intermediate contact part 56 is strip-shaped and is fastened by a pin 59 to a projection 60 which is provided in the recess 40.
  • contact nipples 61, 62 are provided which protrude from one side of the strip.
  • the intermediate contact part 56 is fastened to the projection 60 such that the end section provided with the contact nipple 61 forms a movable section which can be pivoted by the external force in order to bring the contact nipples 61, 58 of the intermediate contact part 56 and the fixed contact part 55 into contact with one another and which rests on the actuating part 51.
  • the other end section with the contact nipple 62 forms a fixed section analogously to the side contact 6.
  • the movable contact part 57 consists of a contact pin 63 and a contact nipple 64 formed integrally therewith at one end of the contact pin 63.
  • the contact pin 63 is arranged axially displaceably in a bore 65.
  • a cylindrical recess 66 is provided which is arranged coaxially to the bore 65.
  • a compression spring 67 is arranged, which on the one hand rests on the contact surface formed by the recess 66 and on the other hand rests on the underside of the contact nipple 64.
  • the compression spring 67 presses the contact nipple 64 into an initial position, which is determined by the actuating part 45.
  • a further cylindrical recess 68 is provided in the side of the body 5 facing the lower part 3, which is formed coaxially to the bore 65.
  • the actuating part 45 is fastened to the pin 63 and lies against the surface formed by the recess 68.
  • the actuating part 45 is made of insulating material and has a cylindrical extension 69 which projects through the bore 44 in the intermediate contact part 36 of the side contact 6, as a result of which the movable contact part 57 of the center contact 7 is insulated from the intermediate contact part 36 of the side contact 6.
  • the switching arrangements are actuated by screwing in the lamp.
  • the contact plate on the lamp presses against the movable contact part 57 of the center contact 7 and displaces it against the force of the compression spring 67.
  • the displacement of the movable contact part 57 brings the contact pin 63 into contact with the contact nipple 62 on the intermediate contact part 56 of the center contact 7 at the same time, the movable section of the intermediate contact part 36 of the side contact 6 is pivoted by the actuating part 45, so that the intermediate contact part 36 and the fixed contact part 35 are brought into contact with one another.
  • a separating path is closed in each switching contact arrangement.
  • the ring 54 is gripped by the thread on the lamp base when the lamp is screwed in and is rotated upward by the rotation of the lamp against the force of the compression springs 52, i. H. pulled away from the body 5.
  • the movable contact part 37 and the intermediate contact part 36 of the side contact 6 are brought into contact with one another and at the same time the movable section of the intermediate contact part 56 and the fixed contact part 55 of the center contact 7 are brought into contact with one another by the actuating part 51 on the holding rod 50.
  • the other isolating path in each switching contact arrangement is closed and the incandescent lamp lights up.
  • the forces acting on the side contact 6 and the center contact 7 are directed in opposite directions in order to close the switch contact arrangement. It is pointed out that the force acting on the side contact 6 can have the same direction as the force acting on the center contact 7. To achieve this, only different elements of the switching arrangement have to be designed and arranged differently, which is within the knowledge of the average person skilled in the art.
