Definitions
- the invention relates to a switching device with a housing and an access opening arranged on its operating side to a connection terminal.
- Such a switching device has one corresponding number of terminals.
- a terminal cover can be used as protection against contact or to prevent a unwanted current branch can be provided.
- From the DE 297 15 050 U1 is a low-voltage switching device with a Terminal cover known for connection to a molded housing part of the switching device is provided.
- the terminal cover can without screw connections as well Tools can be assembled and disassembled.
- a captive terminal cover is out of the DE 37 28 796 A1 known.
- the contact protection movable with the housing or a housing part of a low-voltage switching device connected terminal cover closes arranged on the operating side of the switching device Access openings for clamping screws.
- the terminal cover, with the several terminals of a switching device at the same time can be covered, can be closed without tools. Frequent activity is not intended, especially No information was given on opening the terminal cover become.
- the document DE 88 12 305 U discloses a switching device according to the preamble of claim 1.
- the invention has for its object to provide a switching device a particularly suitable one integrated into the device housing Specify locking of a connection terminal.
- a terminal lock has a Actuating spindle with a cone, rotatably mounted in the housing as well as a slide that rests against this under spring force to close an access opening of the housing. In this way, a compact, integrated into the housing Locking device created.
- the slide has a sloping, lying on the cone of the actuating spindle Contact surface, with a screw movement of the Actuating spindle of the slide is displaceable.
- a special feature compared to the stroke of the actuating spindle long slide travel is according to an expedient Design achievable in that the contact area of the slide is arched. Reach around two interacting with the cone of the actuating spindle Sliding leg of the contact surface in an access opening releasing the first position of the slide the cone semicircular, while in a closing the access opening second position of the slide the slide arm just rest with their leg ends on the cone.
- a den Slider in contact with the cone-holding spring is turned around the more tensioned the farther outside the slide is against the cone, i.e. the closer the slider is to the second position.
- a particularly simple spring mounting is advantageous achieved in that the spring on the free end on Housing is stored.
- a one-piece or one-piece design of the slide with the spring leads to another manufacturing technology Simplification.
- the spring is conveniently on one the slide collar forming the contact surface is formed.
- a separate fastener for fixing the A spring on the slide is therefore not necessary.
- On the sliding collar is also a in the longitudinal direction of the actuating spindle molded stop. That attack prevents the gear lever of the device from being locked Condition moved until the contact is disconnected or closed can be.
- An adjustment of the operating spindle without tools can advantageously be excluded in that the Actuating spindle on the operating side of the switching device instead of a manually operated operating handle has an engagement seat for an operating tool.
- a particularly space-saving adjustment mechanism for the operating spindle is expediently achieved in that this one corresponding to an internal thread of the housing Has external thread.
- the housing 2 of the switching device 1 can its fixing or underside 5 on a (not shown) DIN rail to be attached. For this purpose, it has a locking element 6 on.
- On the top or control side 7 of the Switching device 1 is an operating handle 8, with a switch toggle 9 can be adjusted.
- an adjusting lever 10 is also formed, into which one Actuating rod 11 engages via an auxiliary lever 12 a moving contact 13 can be actuated.
- the electric insulating auxiliary lever 12 is under the tension of a spring 14, the moving contact 13 via the auxiliary lever 12 in Direction of the open position shown presses.
- the moving contact 13 is electrical with its clamped End 15 connected to the other terminal 4.
- the movable end 16 of the moving contact 13 can be rotated the switching knob 9 by means of the actuating handle 8 be brought into contact with a fixed contact 17, the electrically connected to the lockable terminal 3 is.
- the lockable terminal 3 has one Clamping screw 18, which has an access opening 19 in the Operating page 7 is actuated.
- actuating spindle 20 On the operating side 7 of the housing 4 there is an actuating spindle 20 a terminal lock 21 accessible.
- a slide 22 At the Actuating spindle 20 is a slide 22, to which one Spring 23 is formed, the free end 24 abuts the housing 4. The spring 23 exerts a force F on the actuating spindle 20 out.
- the slide 22 In Figure 1, the slide 22 is in a the first position 25, i.e. the access opening 19, i.e. in the open position.
- FIG. 2 shows the switching device 1 with - removed in analogy to FIG. 1 Housing cover, the slider 22 in a Access position 19 closing second position 26, i.e. is held in the closed or closed position.
- the operating spindle 20 is compared to that shown in FIG first position 25 further sunk into the housing 4, i.e. closer to the bottom 5 of the housing 4.
- By the lowered actuating spindle 20 is the slide 22 compared to the first position 25 that this shifted in the illustrated second position 26 the access opening 19 covers.
- the clamping screw 18 can therefore not in the Terminal 3 can be used.
- this has one Engagement receptacle 27 for an operating tool (not shown) and an external thread 28, which with a Internal thread 29 of the housing 4 corresponds.
- Figures 3a and 3b show the actuating spindle 20 with the external thread 28 and with a cone 30 which forms a sliding surface 31.
- the engagement receptacle 27 is for actuation with designed a hexagon socket wrench.
- the slide 22 is in one piece or in one piece Version shown with molded spring 23.
- the slider 22 has a closure plate on its clamp side 32 33 for closing the access opening 19 and at its Spindle side 34 has a sliding collar 35 with a sliding surface 36 on.
- the sliding surface 36 extends over two sliding legs 37, which are shaped such that the cone 30 of Actuating spindle 20 in the first position 25 (FIG 1) approximately is encompassed semicircularly by the sliding legs 37.
- the sliding or contact surface 36 of the slide 22 is here in Adaptation to the cone 30 beveled.
