Abstract

The counter nut has two nut halves (10,12) complementary to a ring, where the nut halves are detachably connected to one another at the areas of two ends. A latching mechanism is provided for locking the ends. The latching mechanism is actuated by radial displacement of the nut halves relative to each other.

Description

The The invention relates to a lock nut.

locknuts are basically known and conventional formed in the form of a closed ring. This closed Ring shape makes it impossible conventional Over nuts to lay laid cables without the cables cut through this or disconnected.

Of the Invention has for its object to provide a locknut which allows easier installation.

to solution The object is a locknut with the features of the claim 1 provided.

The counter nut according to the invention comprises two halves of a mother, complementary to a ring. Of the Invention is in other words based on the general idea to perform the lock nut divisible and in particular of two parts, namely the nut halves to build. Due to its bipartite, the lock nut can, for example, order a cable put together around without disconnecting or disconnecting the cable will need. this makes possible a simple assembly of the lock nut also on laid cables.

Even though the lock nut according to the invention especially good for the formation of a screw around a misplaced cable is suitable, It should be noted that the lock nut according to the invention in principle also can be used in other types of fittings, in particular such glands, through which no cable passes.

advantageous Forms of the invention are the subclaims, the description and to take the drawing.

According to one embodiment are the mother halves in the region of respective first ends releasably connectable to each other. The lock nut can thus be opened at least at the first ends of the nut halves and for example, be placed around a cable.

Around a secure connection of the nut halves in the closed state to ensure the mother-in-law is advantageously a locking mechanism for locking the first ends provided together. The locking mechanism can by a Radial displacement of the nut halves operable relative to each other be. this makes possible a locking or unlocking the nut halves with one hand, whereby the assembly of the locknut is further simplified.

According to one another embodiment are the mother halves in the region of respective second ends inextricably linked together. This prevents on the one hand that one of the nut halves is lost can go, and on the other hand, in particular the one-handed assembly the locknut even further simplified.

Prefers are the mother halves pivotable relative to each other in the region of their second ends connected with each other. The mother halves form in other words a kind of hinge and need for mounting the locknut only to be opened or closed.

The nut halves can a metal material, e.g. Brass or nickel plated brass, or a plastic material. Preferably, both nut halves are made formed the same material. Basically, it is also possible, the nut halves to form of different materials, for. B. a mother half a plastic material and the other nut half of a metal material.

following the invention is based on an advantageous embodiment purely by way of example with reference to the attached drawing described. Show it:

1 a perspective view of a lock nut according to the invention (a) in the closed state and (b) in the open state;

2 different views of a first mother half of the locknut of 1 ; and

3 different views of a second mother half of the locknut of 1 ,

In the 1 illustrated lock nut comprises a first nut half 10 and a second half mother 12 , In the closed state of the locknut ( 1a ) form the mother halves 10 . 12 a closed ring, the inside of which is threaded 14 is provided and a passage 16 defined with a circular cross-section. To screw the lock nut on a thread, the lock nut is around a centrally through the passage 16 extending axis of rotation (not shown) twisted.

At her the thread 14 facing away from each mother half 10 . 12 three adjacent flat surfaces 18 on, so that the mother halves 10 . 12 in the closed state of the locknut ( 1a ) to a uniform hexagonal outer profile. This allows the rotation of the lock nut with the aid of a corresponding tool, for. B. a hexagon wrench.

As in 1b is shown, the nut halves can be 10 . 12 open to install the counter nut. These are the mother halves 10 . 12 in the region of respective first ends 20 respectively. 22 releasably connected to each other and in the region of respective second ends 24 respectively. 26 pivotally connected to each other.

As 1 and 2 show is in the range of the first and second end 20 respectively. 24 the first half of the mother 10 each a slot-shaped receptacle 28 formed in a plane perpendicular to the axis of rotation of the lock nut level in the first nut half 10 extends into it. Through each of the slot-shaped shots 28 extends a pin oriented parallel to the axis of rotation 30 respectively. 31 that in holes 32 is firmly stored in the area of the first end 20 or the second end 24 the first half of the mother 10 are provided accordingly. The pencils 30 . 31 can be positively and / or cohesively with the first half of the mother 10 be connected, z. B. in the holes 32 be pressed and / or glued into this.

As in 1b and 3 is shown, the second nut half 12 in the area of her first end 22 a first tapered extension 34 and in the area of their second end 26 a second tapered extension 36 on.

The one in the area of the first end 22 trained first tapered appendage 34 is with a radially outwardly opening notch or groove 38 provided for receiving in the area of the first end 20 the first half of the mother 10 arranged first pin 30 is trained.

The one in the area of the second end 26 the second half of the mother 12 trained second tapered appendage 36 is with a radially oriented slot 40 provided by which in the region of the second end 24 the first half of the mother 10 arranged second pin 31 extends through. Through the through the slot 40 the second half of the mother 12 extending second pin 31 the first half of the mother 10 is the second half of the mother 12 hinged to the first half of the mother 10 hinged. This is due to the elongated design of the slot 40 not only a pivoting of the nut halves 10 . 12 , but also a shift of the nut halves 10 . 12 in the radial direction relative to each other possible.

The radial dimensions of the groove 38 on the one hand and the long hole 40 on the other hand are chosen so that it - starting from the in 1a illustrated closed state of the lock nut - is possible, the second half of the mother 12 so far relative to the first half of the mother 10 to move, more precisely, to withdraw that the first pen 30 the first half of the mother 10 and the groove 38 the second half of the mother 20 disengaged and the mother halves 10 . 12 can be swung apart.

Conversely, the second half of the mother 12 - starting from the in 1b shown opened state of the lock nut - after folding the nut halves 10 . 12 as far as the first half of the mother 10 be moved, more precisely, be advanced that the first pen 30 the first half of the mother 10 in the groove 38 the second half of the mother 12 engages and prevents unintentional opening of the lock nut. The first pen 30 and the groove 38 in other words, form a latching mechanism through which the first ends 20 . 22 the mother halves 10 . 12 are locked together in the closed state of the lock nut.
