Definitions
- the invention relates to a contact element for an electrical switching device according to the preamble of the independent claim.
- the invention is therefore based on the object of providing a contact element of the type described at the outset which eliminates the disadvantages mentioned.
- the contact element its housing and, in adaptation to it, the actuating plunger are advantageously designed such that the actuating plunger can also be installed in an installed position rotated by 180 ° about its transverse axis.
- the invention also includes electrical switching devices such as, in particular, manually operated command devices, for example pressure switches or rotary switches, in which the contact device is formed by a contact element according to the invention. Furthermore, the invention also includes power switching devices such as Contactors or circuit breakers or the like, in which case the auxiliary switches are formed by contact elements according to the invention.
- Figure 1 a first embodiment of the invention
- Figure 2 the contact element according to Figure 1 in an exploded view
- Figure 3 the plunger arrangement of the contact element according to Figures 1 and 2 in a detailed representation
- Figure 4 the contact element in a perspective view without cover part - as a closer for rear mounting
- Figure 5 the contact element according to Figure 4 in an exploded view
- Figure 6 the plunger arrangement of the contact element according to Figures 4 and 5 in a detailed representation.
- Fig. 1 shows the contact element according to the invention in an embodiment as an opener for front mounting.
- the contact element consists of a housing 2, two fixed contacts 4 with connections for external electrical conductors 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 designed 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 base part 26 and spring means 28, 29, which is made of insulating material , 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 one
- Fixing recess which cooperates with an elevation of the contact bridge 24 to fix it.
- the actuating plunger 20 is designed as a plastic injection-molded part, which, seen in longitudinal section, is a
- the cross leg part 32 is arranged between the longitudinal leg parts in such a way that the longitudinal axis X of the tappet arrangement 6 forms a perpendicular to the contact surfaces of the cross leg part 32.
- the contact surface (s) can also be designed to slope or slope from one longitudinal leg part 30, 31 to the opposite longitudinal leg part 31, 30. This achieves self-cleaning of the contact pieces 12, 22 when they interact.
- the contact bridge 24 can be arranged in position A between the free ends of the longitudinal leg parts 30, 31 and is supported on the housing 2 by the first spring means 28 in the assembled state.
- 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 structure of the contact element according to FIGS. 1-3 is intended for front mounting. By another assembly of the same components, the contact element is also suitable for rear mounting.
- the entire plunger arrangement 6 is rotated by 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 advantageously 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, in each case openings arranged in pairs for the passage of the free ends of the actuating plunger 20.
- the openings on one housing end serve to pass through the free ends of the actuating plunger 20 installed in the contact element, while the other openings arranged in the opposite housing end serve to pass through free ends of an actuating plunger of a contact element built in a piggyback manner, so that a simultaneous actuation of both contact elements 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 shown as a closer for rear mounting (e.g. on a top-hat rail).
- the contact bridge 24 is arranged on the opposite surface B of the cross leg part 32 in the space between the two cross leg parts 32, 33 and is supported on the other cross leg part 33 in the space via the second spring element 29.
- the spring means 28 serves exclusively as a return spring, which is why the foot part 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 groove 34 which runs preferably perpendicular to the longitudinal axis X and is formed on the inside of a longitudinal leg part 30, through which the contact bridge 24 can be inserted into the intermediate space without having to twist it.
