Thus, the risk is prevented that the side hood slides off the actual body. When the first blocking piece hits the actual body, the maximum receiving space is defined.

Further, the above-described rotary member also has a second blocking piece, and when the above-mentioned side hood is in its initial position, the above-mentioned second blocking piece abuts the above-described actual body and defines the minimum receiving space.

In another practical embodiment, this also includes an elastic member, wherein the above-mentioned elastic member in the course of movement of the above-mentioned drive shaft from the open position to the closed position by its elastic force, the above-mentioned side hood for rotation along the direction of extension of advances referred to above recording space. It is possible to drive along with the locking part, which further reduces the external driving force, so that an operation with relatively little external force required is possible, which increases the comfort of the operation.

Further, when the above-described drive axle is in the closed position, the above-described elastic member can block the tendency of the above-mentioned side cover to move to its initial position and the side cover can not easily return to its initial position because of its own weight. Only under the propulsion of external, such as manual force, the elasticity of the elastic part is overcome and returned the lateral hood back to its initial position.

In a practical embodiment, the above-mentioned side hood has a clamping opening, wherein the above-described clamping opening can be clamped to the above-mentioned actual body and thus fixes the above-mentioned side hood. This facilitates the line connection to the operating personnel and allows the switching device to be kept in a relatively stable state, the space occupied being relatively small, which facilitates operations such as logistics.

In a practical embodiment, the above-described actual body comprises an outer housing, wherein the above-described drive shaft is at least partially guided by the above-mentioned outer housing, wherein the above-mentioned clamping opening can be clamped to the above-mentioned outer housing.

The present invention also provides a fuse-switching device comprising any of the above-mentioned switching devices and a fuse provided within the receiving space of the above-described switching device.

This room is the recording room 11 for possible inclusion of the fuse 60 ;
a drive axle 20 where the drive axle 20 an open position ( ) and a closed position ( ) having. When the drive axle 20 is in the open position, there is the switching device 100 in the opened state and also the fuse 60 is not in operation. When the drive axle 20 is in the closed position, the switching device is in the closed state and the fuse 60 is in operation. In the recording room 11 the gradual concentration of warm air and reduction of the temperature increase caused thereby includes the switching device 100 Furthermore:
a movable locking part 30 , wherein the locking part 30 on the actual body 10 may be provided, wherein the locking part 30 a force experiencing part 31 and a force applying part 32 having, wherein the drive axle 20 in the Run the motion from the open position to the closed position force on the force experiencing part 31 can exercise and thus the locking part 30 to push for movement;
a side hood 40 , with the side hood 40 can be made of plastic, and in a rotatable manner to the actual body 10 is provided. In the course of the movement of the drive axle 20 from the open position to the closed position, the side hood rotates 40 under the propulsion of the force applying part 32 of the locking part 30 from its initial position along the direction of expansion of the recording space 11 , By the said "initial position" is meant the position in which the lateral hood 40 when the drive axle is open 20 (ie open state of the switching device) is located (see ).

Because of the Vorantriebs of the locking part 30 can the side hood 40 to some extent "open", so that the recording room 11 the switching device 100 extended. In this way, the switching device has in operation over a relatively large space for receiving the fuse 60 and correspondingly, over a relatively large space for receiving warm air, so that even when heat is generated by the fuse 60 no excessively high temperature increase is effected and the safety of the operation of the switching device is ensured. Because of the expansion of the room also an extension of the uses for the switching device is given, which means a relatively simple possible assembly in the switching device for fuses with relatively large dimensions.

In a practical embodiment, a pair of side covers 40 be provided, wherein the two are provided opposite to each other on the main body and wherein correspondingly of the force-applying part 32 of the locking part 30 also a pair is provided. In the course of the movement of the drive axle 20 from the open position to the closed position drives a force applying part 32 the one side hood 40 progressing while the other force-wielding part 32 the other side hood 40 advances, so that each along the direction of extension of the recording room 11 rotate. Through this conception, the recording room 11 be extended as possible, so that a further reduction of the temperature increase takes place.

In a practical embodiment, the side hood 40 at its far from the above-mentioned drive axle 20 located side an opening 41 on. The opening 41 may have a width of only about 8 millimeters, so that even with the drive axle in the open position 20 and in the open state Schaltvorrichtung the fuse 60 through the opening 41 in the recording room 11 can reach (as in shown).

In a practical embodiment, the side hood 40 a massive area 42 and a heat dissipation member connected thereto 43 on. For example, on both sides of the massive area 42 Provided heat dissipation parts (of course, this can also be provided only on one side). Because the switching device 100 in the two ways can be mounted frontally or laterally, it is when the used way of mounting a streaming within the receiving space 11 located warm air to the side hood 40 causes, possible, that the massive area 42 the warm air blocks and these to the located on both sides heat dissipation parts 43 conducts and, for example, passes through heat dissipation holes, etc., resulting in a relatively uniform temperature at the side hood 40 causes. If the massive area 42 also as a heat dissipation part 43 is designed, the warm air is discharged directly from the area concerned and the heat is relatively concentrated.

Furthermore, at the fuse 60 opposite side of the massive area 42 protruding a plurality of heat separating ribs 421 intended. Because the heat separation ribs 421 Protruding over the surface is the temperature at the heat separation ribs 421 slightly lower compared to the surface. In particular, between the heat separation ribs 421 are provided under the requirements of IP20 distances, it comes even with inadvertent bumping of the operating personnel to the side hood 40 only to contact with the heat separation ribs 421 which avoids the risk of burns.

In a practical embodiment, the above-mentioned side hood 40 a turned part 44 on, with the rotating part 44 a first blockage piece 441 having, wherein the lateral hood 40 through the rotating part 44 in a movable manner on the actual body 10 is provided, wherein in the course of the pre-drive by the force-performing part 32 by the abutment of the first blocking piece 441 to the actual body 10 the range of motion of the side hood 40 is limited. Thus, the risk is prevented that the lateral hood 40 from the actual body 10 slides down.

On the rotary part 44 a rotating groove may be provided while on the switch 13 of the actual body 10 a protruding axis of rotation is provided. The turned part 44 is provided close to the rotary groove tuned to the axis of rotation and can relative to the switch 13 make a turn in a certain range. Of course, a person skilled in the relevant technical field, that other devices can be provided, for example, the rotary part 44 is formed with a rotation axis and on the switch 13 a turning groove is provided.

Furthermore, the above-mentioned rotary member 44 also a second block 442 on, where, when the side hood 40 in its initial position, the second blocking piece 442 to the actual body 10 bumps and the minimum value of the recording room 11 Are defined.

In another practical embodiment, the switching device also comprises an elastic part 50 For example, a torsion spring, etc., wherein the elastic member 50 in the course of the movement of the drive axle 20 from the open position to the closed position by its elasticity, the lateral hood 40 for rotation along the direction of extension of the above-mentioned receiving space 11 drives. Thus, apart from the pre-drive by the force-performing part 32 of the locking part 30 also the pre-drive through the elastic part 50 possible, so that the requirements for the external driving force are further reduced, which increases the comfort of the operation.

Furthermore, if the drive axle 20 is in the closed position, the elastic part 50 the tendency of the lateral hood 40 block to move to their initial position and located in mounting position switching device is the side hood 40 in the vertical state. Even if the side hood in question 40 is opened to the current position, the side hood can not simply return to its initial position due to its own weight. Only under the propulsion of external, about manual force is the elasticity of the elastic part 50 overcome and the lateral hood 40 led back to their initial position.

In a practical embodiment, the side hood 40 a clamping opening 45 on, with the clamping opening 45 on the actual body 10 can be clamped and thus the side hood 40 attached. This facilitates the line connection to the operating personnel and allows the switching device to be kept in a relatively stable state, the space occupied being relatively small, which facilitates operations such as logistics.

In a practical embodiment, the actual body 10 an outer casing 12 include, wherein the drive axle 20 at least partially by the on the outer housing 12 located hole 122 is guided. Notwithstanding the provision of the lateral hood 40 in a movable manner on the switch 13 can the side hood 40 also in a rotatable manner on the outer housing 12 be provided. Of course, the clamping opening 45 also at the survey 121 of the outer housing 12 be clamped. Now takes place on the basis of - and a practical embodiment, the explanation of the movement.

As in and shown is the side hood 40 when the switching device is in the open state, in the initial position. The space occupied by the switching device is minimal and correspondingly minimal is the receiving space 11 for the fuse 60 , The second block piece 442 abuts the actual body 10 and the side hood 40 can not continue to turn inward, leaving the side hood 40 through its clamping opening 45 is clamped to the main body, which is a relatively fixed position of the lateral hood 40 causes.

When the operation of the fuse 60 is required, the drive shaft rotates 20 from its open position counterclockwise to the closed position and accordingly decreases the drive axle 20 the power experiencing part 31 on the locking part 30 with and continues to drive on the locking part 30 located force exercising part 32 the lateral hood 40 to turn outwards. The elastic part 50 (For example, a torsion spring) simultaneously drives the lateral hood due to its accumulated elasticity 40 to turn outwards. The clamping opening 45 the lateral hood 40 gradually leaves the previous fixed position and turns outward along the expansion tendency of the receiving space 11 ,

As in and shown pushes when the drive axle 20 reached their closed position, that at the side hood 40 located first block piece 441 to the actual body 10 and blocks the further rotation of the side hood 40 , The lateral hood 40 is in the maximum position after opening and accordingly is the receiving space 11 in the maximum state. The elastic part 50 still has a certain elasticity. Even with pre-drive the side hood 40 by external force to attempt to return to its initial position, the mechanism now generates because of the still in the closed position drive axle 20 sufficient resistance to movement of the locking part 30 to prevent and thus the rotation of the lateral hood 40 prevented inside.

If the return of the lateral hood 40 required in the initial position is the drive axle 20 first switch to its open position, with the side hood 40 the resistance of the locking part 30 loses. Only by pushing the side hood 40 inside can the elasticity of the elastic part 50 overcome and its compression are effected, the clamping opening 45 the lateral hood 40 on the actual body 10 is attached. Now, this bumps on the side hood 40 located second block piece 442 to the actual body 10 and even with the application of force there is no further rotation of the lateral hood 40 inside. Now, the switching device is in the open state and the side hood 40 returns to its initial position.

The present invention also provides a fuse-switching device 60 ready, which any of the above switching devices and one in the receiving space 11 the switching device located fuse 60 having. In this way, the switching device has a relatively large space for receiving the fuse during operation 60 and even when heat is generated by the fuse 60 There is no excessive increase in temperature and the safety of the operation of the switching device is guaranteed. At the same time, the relatively large receiving space also offers the possibility of mounting fuses of relatively large dimensions.
