Definitions
- the invention relates to a switching device with a first movable contact carrier, which has a first cutout, into which a lock engages via a first housing opening of the switching device, depending on the operating state, in a spring-loaded manner.
- US 4,385,214 discloses two push buttons which are connected to one another by a locking mechanism. This ensures that only the contact of one push button can be closed, while that of the other push button remains in the open state.
- a switching device with mechanical locking of moving parts is known.
- a mechanical interlocking of parallel moving parts and parts for example of shift sets in switching devices, is disclosed, which does not require any special adjustment measures and is easy for the customer to assemble.
- a locking piece ensures that, for example, switching heads O 97/22985 PC17DE96 / 02316
- Another object of the invention is to design the switching device in such a way that the mechanical latching can be released with the aid of an electrical signal.
- the first-mentioned object is achieved according to the invention in that the lock engages in the first recess when the switching device changes to the ON position, and in that the switching device is connected to an unlocking device which has a second movable contact carrier in which a second recess is present, into which a first arm of a rotatably mounted angle lever engages via a second housing opening of the unlocking device in the OFF position and which swivels when the unlocking device is switched on in such a way that it actuates the lock with its second arm and thus releases the first contact carrier .
- the lock is designed as a pawl, which is rotatably mounted in a bearing, since the pawl can be designed as a part that takes up little space and the bearing can be used in the same design as in reversible combinations, for example by shooters. This makes the warehouse a part that can be manufactured inexpensively in large quantities.
- first housing opening is provided in a first side wall of the switching device and if the second housing opening is provided in a second side wall of the unlocking device.
- first switching device e.g. a contactor to be expanded by an auxiliary switch attachment on the front.
- the device design on the front can be retained and the risk of contamination can be kept low.
- the bearing is form-coded and the switchgear and the unlocking device have openings adapted to the first and second side walls of the form-coding, to which the bearing is received in a form-fitting manner, then an inverted construction of the bearing and the pawl can be prevented.
- 1 shows a section of a unit consisting of a switching device and an unlocking device with mechanical latching in the OFF state
- 2 shows the unit according to FIG. 1 in the ON state of the switching device
- FIG. 3 shows a bearing and a pawl of the mechanical latch according to FIG. 1
- FIG. 4 shows an angle lever of the mechanical latch according to FIG. 1
- FIG. 5 shows a basic design of housing openings in the side walls of the switching device and the unlocking device for receiving a form-coded bearing of the mechanical latch
- FIG. 6 shows an exploded view of a switching device with mechanical latching and with an unlocking device.
- a switching device 1 shows a mechanical latching of a switching device 1, for example a contactor, from which a section of the housing with a first housing opening 2 in a first side wall 3 and a first contact carrier 4 with a first recess 5 can be seen, which is the first housing opening 2 opposite.
- Parallel to the first side wall 3 is a second side wall 6 of an unlocking device 7 connected to the switching device 1, for example a further protection, which has a second contact carrier 8 with a second recess 9, which also has a second housing opening in the second side wall 6 - Opposition 10 is opposite.
- a lock designed as a pawl 11 is rotatably mounted in a form-coded bearing 12 between the two rare walls 3, 6.
- the bearing 12 is in its shape-coded openings 13, 14 according to FIG.
- OFF state of the first contact carrier is in an upper tion Posi ⁇ and the pawl 11 is supported below the first training savings 5 on the first contact carrier 4 from.
- a second arm 18 of the angle lever 16 is angled at 90 ° to the first arm between the pawl 11 and the first contact carrier 4.
- Unlocking can also be done manually via the switch position indicator 23 of the contact carrier 8.
- the design of the pawl 11 and the angle lever 16 is shown in detail in FIGS. 3 and 4.
- the pawl 11 is rotatably supported by means of pins 20 and has a bevelled projection 19 at the end which, when mechanically latched, plunges into the likewise notched first recess 5 of the first contact carrier 4.
- the bevels allow tolerance compensation in a simple manner.
- the angle lever 16 is provided with a recess 21 through which the pawl 11 dips in the assembled state.
- the second arm 18 of the angle lever 16 has at the end a web 22 delimiting the recess 21, which pivots the pawl 11 when unlocked.
- the bearing 12 is shape-coded by a hammer-head-shaped design on one side in order to ensure that it is installed laterally in the adapted openings 13, 14 in the Ensure side walls 3, 6 of the switching device 1 and of the unlocking device 7 as indicated in FIG. 5.
- FIG. 6 shows a contactor 1 with the individual parts 11, 12, 15, 16 required for mechanical locking and unlocking, including the unlocking device 7.
- the contactor 1 and the unlocking device 7 are held together by connecting elements 24 which are clamped onto laterally projecting ribs.
- the design of the mechanical latching and unlocking according to the invention is characterized in that contactors manufactured in series can be used as switching devices and as unlocking devices.
- the upgrade of a contactor with a mechanical latch can be carried out quickly and easily by the customer using fewer parts.
