Pattern description

The subject of the utility model is an electric switch with a parking function, in particular a low voltage strip fuse switch. From the publication of the European patent application No. EP 0563530 a strip connector is known having a plate-shaped security element in the connector cover with lugs engaging in special recesses of the housing.

It is also known from the German utility model DE 29622550 U1 a slat switch, in which parking is achieved by placing fusible links in cover inserts detachably attached to supports.

A strip connector is known from the patent application EP 0563530 A1 having a rigid mechanical connecting lever, having a binding element formed as a pivot pin, which is guided in a longitudinal opening in the side wall, and having a second binding element formed in the form of a bearing pin, which is guided in the longitudinal recess. in the side wall.

It is known from the patent application EP 1585156 a strip connector having a handle including at least one locking element engaging with catches in the housing.

A strip connector is known from the patent application EP 2031622, in which the parking of the apparatus is achieved by embedding the abutment surfaces in the handle on the upper part of the pins in the housing. There are also known solutions in which parking is achieved by hanging the rotated cover by an angle of 180 ° together with the fuse links in the switch disconnector housing. An electrical connector with a parking function according to a design, having a movable cover, a lever including at least one abutment surface, a housing and a base, is characterized in that in the housing on the internal walls there are seventh bumpers, against which, in the parked position of the disconnector, abutment surfaces located in the handle rest .

The advantage of the solution is that in the parked position, the user can be sure that the cover with fuse links placed in it or without fuse links, thanks to the use of four support points in the housing in the form of additional bumpers and the upper surfaces of drive pins, will be firmly seated in the parked position without the possibility of its being pressed into the housing, which could lead to contact of the fuse link knives with the jaw contacts of the disconnector, endangering the operator or lead to a failure.

The object of the utility model is shown in the drawing, in which fig. 1 - is a cross-section of the disconnector parked in an axonometric view, fig. 2 - detail A of the disconnector from fig. 1 in an axonometric view, fig. 3 - a complete cover in an axonometric view, fig. 4 axonometric projection side view, fig. 5 axonometric side view releasing member, fig. 6 axonometric front view cover, fig. 7 axonometric front view cover, fig. front view, fig. 8 - detail B of the cover in fig. 7, fig. 9 - casing in an axonometric view, fig. 10 - detail C of the casing in fig. 9, fig. 11 - detail D of the casing in fig. 9, fig. 12 - handle in axonometric view. The electrical connector according to the utility model comprises a complete base 1 with a housing 2 and a complete cover 3 located thereon.

Complete cover 3 includes cover 4, handle 5, release element 6 and three lenses 7.

The cover 4 on the first side parts 8 has first pins 9 with first flanges 10 and oval holes H. The first pins 9 cooperate with cutouts 12 in the second side parts 13 of the handle 5.

On the inner sides of the second side parts 13 of the handle 5 there are second pins 14 with second flanges 15 which cooperate with the oval holes H located in the first side parts 8 of the cover 4.

On the first side parts 8 of the cover 4 there are first positioning elements 16 which, in the open position of the disconnector, snap into the first openings 17 in the second side parts 13 of the handle 5 and keep the handle 5 in the open position.

The cover 4 includes first guiding bars 18 and second guiding bars 19 that slidably cooperate with guides 20 located in the housing 2. The first guiding bars 18

Claims (1)

3 PL 66 396 Υ1 include second openings 21 which, in the closed or parked position of the disconnector, engage second positioning elements 22 located on the second side portions 13 of the handle 5, keeping the handle 5 in the closed position. The release element 6 has a third opening 27 in the third side part 23, in which a third pin 25 is located on the partition 24 in the cover 4. This connection allows the release element 6 to rotate in relation to the cover 4. The cover 4 in the head part 28 has a rectangular opening 29, in in which the gripping part 30 of the release element 6 moves in an arc. The third side part 23 of the release element 6 comprises a fifth bumper 26 which, when opened or parked, rests against the sixth bumper 31 in the casing 2, preventing the removal of the complete cover 3 from the casing 2. In order to remove the complete cover 3 from the housing 2, the gripping part 30 of the release element 6 must be moved to the right to the extreme position. In this position, the fifth bumper 26 of the release element 6 moves past the sixth bumper 31 in the housing 2. By re-inserting the complete cover 3 into the housing 2 in order to park the apparatus, the gripping part 30 of the release element 6 may be in any position, while the handle 5 should be in any position. be in the closed position of the disconnector. If the grip portion 30 of the release member 6 is in the rightmost position, then the first sliding surface 43 located on the fifth stop 26 of the release member 6 will slide over the first guiding surface 44 in the housing 2, causing the release member 6 to rotate and the fifth stop 26 to move to its position. preventing the removal of the complete cover 3 from the housing 2. When the gripping part 30 of the release element 6 is in a position other than the rightmost, the second sliding surface 45 located on the fifth stop 26 of the release element 6 moves along the second guide surface 46 in the housing 2, and then the first sliding surface 43 located on the fifth stop 26 of the release member 6 slides over the first guiding surface 44 in the housing 2, causing the release member 6 to rotate and the fifth stop 26 to move to a position preventing the complete cover 3 from being removed from the housing 2. In the housing 2, on the internal walls 35 there are seventh bumpers 32, against which, in the parked position of the disconnector, the stop surfaces 33 in the handle 5 rest. The housing 2 includes fourth pins 36 against which, in the parked position of the disconnector, the stop surfaces 37 located in the handle rest. 5, while during the switching operations the fourth pins 36 cooperate with the cutouts 34 in the second side portions 13 of the handle 5 and constitute an anchoring point for them. Due to the abutment surfaces 33 against the seventh stops 32 and the abutment surfaces 37 against the upper part of the fourth pins 36, the complete cover 3 in the parked position of the disconnector is in a stable position without the possibility of pressing it inside the housing, while its removal is prevented by the fifth stop 26 which rests against a sixth stop 31 in the housing 2. Protective claim An electrical switch with parking function having a movable cover, a lever including at least one abutment surface, a housing and a base, characterized in that in the housing (2) on the inner walls (35) There are bumpers (32) on which, in the parked position of the disconnector, the stop surfaces (33) in the handle (5) rest.
