Definitions

  • the invention relates to an electrical switching device for an electrical Switching device according to the preamble of the independent claim.
  • the invention is therefore based on the object of a switching device to create the type described above, which has the disadvantages mentioned eliminated.
  • the housing and in Adaptation of the actuating plunger advantageously formed such that the actuating plunger also in a 180 ° degree about its transverse axis twisted installation position is mountable.
  • the invention also includes electrical switching devices such as in particular manually operated command devices, e.g. Pressure or rotary switch, at which the contact device by a switching device according to the invention is formed. Furthermore, the invention also includes power switching devices such as Contactors or circuit breakers or the like, in which case the Auxiliary switch formed by a switching device according to the invention become.
  • electrical switching devices such as in particular manually operated command devices, e.g. Pressure or rotary switch, at which the contact device by a switching device according to the invention is formed.
  • power switching devices such as Contactors or circuit breakers or the like, in which case the Auxiliary switch formed by a switching device according to the invention become.
  • Fig. 1 shows the switching device according to the invention in an embodiment as Opener for front mounting.
  • the switching device consists of a Housing 2, two fixed contacts 4 with connections for external electrical Ladder and a plunger arrangement 6.
  • the housing 2 is advantageously formed in two parts, consisting of a base part 8 carrying the plunger arrangement 6 and the fixed contacts 4 and a cover part 10 (FIG. 2).
  • Each fixed contact 4 is formed here in the form of screw connections consisting of a contact plate 14 carrying a contact piece 12, a clamping screw 16 and a pressure plate 18 for the clamping reception of external conductor connections.
  • tension spring terminals or other types of connection can also be used.
  • the plunger arrangement 6 comprises an actuating plunger 20, a contact bridge 24 carrying two contact pieces 22, preferably a foot part 26 and spring means 28, 29 made of insulating material.
  • the plunger arrangement 6 is designed such that the contact bridge 24 is in two different axially spaced apart , Positions on the actuating plunger 20 can be arranged.
  • a first position is position A, in which actuating plunger 20 is designed as an opening plunger (FIGS. 1-3) and a second position is position B, in which actuating plunger 20 is designed as closing plunger (FIGS. 4-6).
  • the foot part 26 which electrically insulates the contact bridge 24 in the first position A from the spring means 28, is essentially square, cuboid-shaped and has a blind hole-like recess on its side facing the spring 28 for receiving it.
  • the four virtual edges of the foot part 26 which run in the longitudinal direction are designed as grooves which cooperate with inward-pointing extensions of the longitudinal leg parts 30 for the purpose of guidance.
  • the foot part 26 is designed in such a way that it can be mounted in all four rotated positions, which in addition further simplifies assembly.
  • the foot part 26 On its side facing the contact bridge 24, the foot part 26 has a fixing recess which interacts with an elevation of the contact bridge 24 in order to fix it.
  • the actuating plunger is 20 formed as a plastic injection molded part, seen in longitudinal section Has double H shape and two longitudinal leg parts 30, 31 and two Cross leg parts 32, 33, the two opposite the Surfaces of the cross leg part 32 defining positions A and B one contact surface each for the contact bridge 24 in the respective break contact or make closer position.
  • the cross leg part 32 is between arranged the longitudinal leg parts that the longitudinal axis X of Ram arrangement 6 a perpendicular on at least one of the contact surfaces of the Cross leg portion 32 forms.
  • the or the contact surface (s) can also slope downwards or upwards from a longitudinal leg part 30, 31 to the opposite longitudinal leg part 31, 30 may be formed. This will self-cleaning the Contact pieces 12, 22 reached in their interaction.
  • the contact bridge 24 can be arranged in position A between the free ends of the longitudinal leg parts 30, 31 and in the assembled state is supported on the housing 2 by the first spring means 28.
  • the spring means 28 serves here as a return spring for the plunger arrangement 6 and at the same time as a contact pressure spring for the contact bridge 24.
  • the switching device according to FIGS. 1-3 is designed for front mounting. By another assembly of the same components, the switching device is also suitable for rear mounting. For this purpose, starting from the component arrangement shown, the entire plunger arrangement 6 is rotated through 180 ° about its transverse axis Y, so that the spring element 28 is supported on the opposite housing wall (not shown).
  • the base part 8 of the housing 2 is also structurally adapted to the actuating plunger 20.
  • the base part 8 has, on its opposite end faces which run transversely to the direction of movement of the actuating plunger 20, openings arranged in pairs for carrying out the free ends of the actuating plunger 20.
  • the openings on one side of the housing serve for the passage of the free ends of the operating plunger 20 installed in the switching device, while the other openings arranged in the opposite housing side serve for the implementation of free ends of an operating plunger of a switching device built in a piggyback manner, so that a simultaneous actuation of both Switching devices is possible. If the fixed contacts 4 are not provided with contact pieces 12 on both sides, these are also to be exchanged for fixed contacts 4 with corresponding contact pieces.
  • the contact arrangement is as a closer for the back Assembly (e.g. on a top hat rail) shown.
  • This version is the Contact bridge 24 on the opposite surface B of the Cross leg portion 32 in the space between the two Cross leg parts 32, 33 arranged and via the second spring element 29 supported in the space on other cross leg part 33.
  • the spring means 28 serves exclusively as a return spring, which is why the foot section 26 can also be omitted here.
  • the contact pressure on the Contact bridge 24 is ensured by the additional spring means 29.
  • At least one is preferably vertical to the longitudinal axis X, on the inside of a longitudinal leg part 30 trained groove 34 through which the contact bridge 24 without it need to twist, can be inserted into the space.
  • the present invention is not based on those described above Embodiments limited, but also includes all in the sense of Invention equivalent embodiments.
