Definitions
- the invention relates to an earthing plug with an earthing clip and / or another Grounding means and with pins, each in a connector insertion opening of a socket bottom are insertable, and with a hood, in which at least one pin as an expansion body with expansion elements is formed and the spreading elements in the inserted state of the grounding plug in the hood guided locking elements are lockable and in the locked state with undercut steps reach behind the edges of the pin insertion openings.
- Plugs and earthing plugs for protective contact systems cannot normally be locked.
- the plug in inserted state must be lockable.
- the lock may only be released with the aid of a tool his.
- Lockable plugs are known from the printed publications GB 2 171 265 A and WO 93/22807 A1. Unlocking is however easily possible without tools, so that the regulations mentioned not be met.
- a generic connector is known from GB 2 224 892 A. You can also lock it there by actuating a lever or the like protruding through the hood so that the Plug does not meet the safety regulations mentioned.
- the object of the invention is such a design of the plug or grounding plug that the Locking can only be lifted using a tool.
- two expansion bodies each as Hollow pins are formed with a channel that the locking elements designed as locking pins are each insertable into a channel of a hollow pin that the locking pins on a Latch slide slide, which can be moved in a slot in the hood, in the inserted state with the outer contour of the hood is flush and a recess for attaching a blade-like Tool and that in the peripheral wall of each hollow pin at least one through axial slots free spreader bar is provided with an undercut level, through which in the channel inserted locking pin is locked against evasion inwards .
- the invention differs from the prior art in that it is in the inserted state of the grounding plug into the socket that reaches behind the edges of the plug insertion openings Spreading elements by the locking pins sitting on the locking slide in a positive manner in the locking position being held. You can only intervene in the bolt slide with one tool and release the lock. The bolt slide can not be gripped with your fingers from the outside and actuate.
- the operation by a tool is made possible by the fact that for inserting a blade-like Tool on the head part of the slot aligned a groove on a recess of the bolt slide is.
- a firm and positive locking is achieved in that the inner profile of the channel is completely filled in by the respective locking pin.
- a contour plug in particular a protective contact plug 1 with two pin-shaped expansion bodies 2 arranged according to the connector pins, with guide cams 3 and with axial slots 4 for a protective contact spring, not shown.
- the order is surrounded by a hood 5.
- the electrical connection lines, in this case the earthing line are also not shown.
- the expansion body 2 are preferably integrally formed with a plug bridge, not shown.
- Each expansion body 2 is designed as a hollow pin.
- the peripheral wall 6 of the hollow pin has several spreading webs 8 separated by longitudinal slots 7, each with an undercut step 9.
- the peripheral wall 6 encloses a channel 10 in which a locking pin 11 is axially displaceable.
- the locking pin 11 fills the channel 10 in a form-fitting manner, as is shown in particular in FIG. 6, and holds it Spreader bars 8 in a spread state so that they cannot deflect inwards in the radial direction and the undercut levels 9 are effective ..
- the locking slide 12 has a head Recess 15, to which an inclined groove 16 of the hood 5 is aligned.
- the locking slide 12 is contoured according to the hood 5, so that it is in the inserted state according to FIGS. 2 and 4 with the The outer contour of the hood 5 is flush and therefore no touch is possible. Pulling out the Latch slide 12 is only possible if you use a blade-like tool in the recess 15 intervenes.
- Fig. 5 shows schematically the bowl 18 of a socket with a socket bottom 17, in which two Connector pin insertion openings 19 for connector pins or expansion body 2 are provided.
- the locking pins 11 on the locking slide 12 th pulled out of the channels 10 of the hollow pins. So that the expansion bars 8 of the hollow pins when Dodge passage through the connector pin insertion openings inwards so that the hollow pins or Expanding body 2 can be inserted through the connector pin insertion openings 19 unhindered.
- the spreading webs 8 are thus pushed radially outward and can no longer move back away inside.
- the undercut steps 9 each come with the edges of the pin insertion openings 19 engaged so that the grounding plug is locked and not pulled out of the socket can be.
