Definitions
- the invention relates to a single-pole circuit breaker with a housing in which a fixed and a movable contact are arranged, which are connected to terminals, the movable contact being arranged on a switching bridge which is movably mounted in the housing and which has a switching button via an intermediate lever is connected, and wherein the intermediate lever slides along when actuating the switch button with one end on a control link with two end stops on the switch button.
- the invention further relates to a single-pole circuit breaker with a housing in which a fixed and a movable contact are arranged, which are connected to connecting terminals, the movable contact being arranged on a switching bridge which is movably mounted in the housing and which is connected to a switching button via a Intermediate lever is connected, and wherein the intermediate lever slides with one end on a control link with two end stops on the switching bridge when the switch button is actuated.
- Switches in which an intermediate lever slides between a switch button and a switching bridge in a control link on the switching button or on the switching bridge are known from GB 1 552 180 A and GB 2 157 499 A.
- the object of the invention is to provide a circuit breaker in which the described welding of the contacts is prevented as far as possible.
- the invention takes advantage of the fact that the shorter the switch-on process, the smaller the melting of the contacts and subsequent welding of the same, i.e. the faster the contacts close.
- the control link which is arranged either on the switching bridge or preferably on the switching button, the intermediate lever can move freely along the control link from a certain switching path when it is switched on, without being tied to the movement of the switching button, as a result of which the contacts are unimpeded can close very quickly.
- the intermediate lever When the switch is closed, the intermediate lever bears against this contact surface until the contacts are almost closed and then slides off and on the control link freely until the contacts are closed. Due to the very short distance between the two contacts at the time the intermediate lever slides off the contact surface, the impact speed of the movable contact on the fixed contact is so low that the described multiple lifting of the movable contact from the fixed contact is practically full ⁇ can be avoided at all times, but still so large that the contacts cannot be welded together.
- a stop is arranged on the switch button, which stops the intermediate lever during the switch-on movement in the ON position.
- the stop on the switch button moves the intermediate lever along the control link, in particular pushes it away from the contact surface when the distance between the two contacts has reached a predetermined value, so that the point in time when the intermediate lever slides off the contact surface ie At what distance between the two contacts this occurs, is not influenced by manufacturing inaccuracies or signs of wear on the contact surface.
- Fig. 4 shows the switching mechanism of the switch on an enlarged scale in an intermediate position
- the switch according to the invention essentially consists of a housing with a lower shell 1 and an upper shell 2, in which connection terminals 10, 11 are received in a manner known per se.
- the connecting terminal 10 is connected via a round cable 8 to a switching bridge 4 which is mounted at one end on a bolt 13 in the housing 1, 2.
- a switching bridge 4 which is mounted at one end on a bolt 13 in the housing 1, 2.
- a movable contact 14 At the other end of the Switching bridge 4 there is a movable contact 14, which cooperates with a stationary contact 15 in order (in the switched-on state of the switch) to establish an electrical connection between a circuit board 12 to which the contact 15 and the second connecting terminal 11 are attached to produce terminals 10 and 11.
- An angled end 16 of an essentially U-shaped intermediate lever 6 is mounted approximately in the central region of the switching bridge 4.
- the intermediate lever 6 can be a wire bracket, for example.
- the other angled end 17 of the intermediate lever 6 is received in a recess or groove 18 in a switch button 3 which is rotatably mounted in the housing 1, 2.
- the recess 18 is delimited on the side facing away from the switching bridge 4 by a control link 19 (FIG. 5), on which the intermediate lever 6 is supported with its angled end 17, loaded by the force of a spring 7, and slides along it.
- the spring 7 is a compression spring which is supported on the one hand on the switching bridge 4 and on the other hand on the housing 1, 2.
- control link 19 or the recess 18 is delimited by end stops 20, 21.
- An elevation 22 is arranged in the central region of the control slide 19, somewhat offset towards the end stop 20, and forms an abutment surface 23 for the intermediate lever 6.
- the switch according to the invention is switched on starting from the OFF position shown in FIG. 3 by actuating the switch button 3 counterclockwise, the intermediate lever 6 slides after the dead center, at which the axis of rotation of the switch button 3 approximately in the extension of the Intermediate lever 6 lies, has been overcome, with its end 17 initially away from the end stop 21 into the position shown in FIG. 4, in which the end 17 bears against the contact surface 23, as a result of which the "uncontrolled" closing movement of the switching bridge 4 on the stationary one Contact 15 is initially inhibited. In this position, the two contacts 14 and 15 are only about 1 mm apart, for example.
- a stop 25 is also arranged on the switch button 3, which abuts the intermediate lever 6 in the position shown in FIG. 4 and pushes it downward from the contact surface 23 when the switch button 3 moves counterclockwise.
- the switch button 3 is first turned clockwise until the end 17 of the intermediate lever 6 rests against the end stop 20.
- the movable contact 14 is then lifted off the stationary contact 15 by further turning the switch button 3.
- the intermediate lever 6 After the intermediate lever 6 has again overcome the dead center, it jumps over the elevation 22 on the control link with its end 17 to the left to the end stop 21 and presses the switch button 3 further in a clockwise direction until it hits a stop surface 26 Ge 1, 2 abuts.
- the switch button and the switching bridge can be mounted in the housing so that they cannot be rotated but can be moved in translation.
- the tax scenes instead of on the switching button 3 on the switching bridge 4 an ⁇ arranged.
- no contact surface is provided on the control link and the movement of the intermediate lever on the control link is possibly only supported by the stop 25.
- a single-pole switch has a housing 1, 2, in which a fixed 14 and a movable contact 15 are arranged, which are connected to terminals 10, 11.
- the movable contact 14 is arranged on a switch bridge 4 which is pivotably mounted in the housing 1, 2 and which is connected to the switch button 3 via an intermediate lever 6.
- the switching bridge 4 is loaded into the closed position by the force of a spring 7.
- the intermediate lever 6 slides when the switch button 3 is actuated with one end 17 along a control link 19 on the switch button 3, which has two end stops 20, 21 and between the end stops 20, 21 a contact surface 23 on which the intermediate lever 6 during the Switch-on movement is temporarily supported.
- the control link 19 with the contact surface 23 makes it possible for the contacts 14, 15 to close quickly, but not so quickly that the movable contact 14 "vibrates” at the fixed contact 15, so that it does not become welded of contacts 14, 15 comes.
