The invention relates to an articulated fuse. Articulated fuzes in several designs are known- In one known Ansführungart the buckling rod is composed of five pipe trains and a blade surround. In this embodiment, the detonator housing takes a spring bushing with a firing pin and Compression spring 'on. This is slidably mounted and by bolts and tear bars on the lower draw hook hung up. In a further known construction of a tick igniter, the knee igniter consists of a "o Copper cylinder with a constricted firing pin shaft; With the Knickmomenf, the firing pin shaft breaks at the constricted point and brings the detonator to function.

Articulated mines are also known, but they are heavy and »5 robust. A well-known kink mine also only has a single predetermined breaking point, d. That is, the mine can only be triggered at a certain point. One Another well-known articulated mine has a thick-walled tube that resists collisions of the usual kind The mine has an obliquely pointed foot with which it can be driven into the ground. Within The tube is another tube which contains a liquid primer. When the hemp pipe breaks the second pipe will also be broken. The primer ignites the explosive charge, which is used to Detonated. A redesign for use as a detonator was not possible because it was suitable Safety regulations cannot be attached.

The known articulated fuses and articulated mines are due to the military demands made today too complicated and can give rise to failure in practical use, since they do not fit into the desired shape, i.e. they cannot indiscriminately deep in frozen ground, in rock or built into compact ice mass. Also if she is. are partially spilled after installation, triggering is no longer possible.

The invention is based on the object of avoiding the deficiencies indicated and of providing an articulated fuse to create, with which with great simplicity also the greatest function and possibility of bending over the whole Length of the guide tube is guaranteed. This is achieved by the fact that with almost the same, and indeed more dearly Length of the guide tube and the firing pin extension, the firing pin extension made of temperature-resistant Made of plastic. Here it is essentially important that both parts which are sensitive to kinking have a great length.

In the drawing, an example of an embodiment of the articulated fuse is shown in longitudinal section.

The articulated igniter consists essentially of the igniter housing 1, the guide tube 7 and the percussion

Bolt extension made from easily breakable, temperature-resistant plastic. The firing pin extension 6 is housed in the guide tube and has almost the entire length of the guide tube. the The wall thickness of the guide tube is kept weak, and the tube is made of an alloy in which one great kink sensitivity is possible. The firing pin spring 11 is held by a retaining pin 5 at the top The end of the firing pin extension is held cocked Position of the guide tube lateral pressure, regardless of where the counter bearing for the guide tube is, this kinks the guide tube and breaks the plastic firing pin extension. The released firing pin strikes the squib and ignites it. The jet of fire from the squib ignites then the detonator, the impact of which detonates the surrounding explosives.

The firing pin extension 6 made of fragile plastic has two cast-in on both sides Retaining tabs 9, one for fastening the firing pin and the other for fastening the retaining pin 5 serve. The Haitestift is secured against slipping through the sleeve 4, which is given in between is firmly driven by sealing lacquer onto the guide tube and subsequently through an annular joint seal 17 is closed watertight with the guide tube. Firing pin, retaining tabs and the circular ones Disks 10, which are used for the central guidance of the firing pin, are simple, easy to manufacture economically Stamped parts and are made from sheet metal

The firing pin 12 is set down at the end 8, is inserted into the retaining tab 9, which has a hole, and is at right angles bent around. This creates a simple but extremely durable connection between the firing pin and the contact bolt extension.

The Stabilisatiortsfuß 3 can be screwed onto the »end of the detonator housing, its lower edge during installation of the detonator in a mine firmly on the lid

Claims (2)

The stabilizing foot prevents the connection thread from breaking off from the filler nipple and absorbs the leverage that occurs when the articulated fuse breaks out. With this arrangement of a stabilizing foot, a light, small in diameter and elegant design of an articulated fuse is possible. In other articulated fuses, the diameter of the foot nipple is so large that it also serves as a stabilization support. The disadvantage of this known arrangement is that these detonators are large in diameter and heavy in construction. The foot nipple is screwed into the detonator housing and carries the crimped squib. 3 ff. The connection thread on the filler nipple t «'is sealed watertight with a screw cap 13, which is lined with paraffin. In addition to this seal, the detonator is further protected against the ingress of moisture, dirt, etc. by the annular joint seal 15, 16 and 17. A sealing washer 14 is again attached below the guide tube, which is provided for the special sealing of the firing pin spring chamber and thus also for protecting the squib. In a wetter version of the articulated fuse, a delay tube can also be screwed into the foot nipple 2. In this case, the inner bore of the filler nipple as is equipped with a thread into which the delay tube can then be easily screwed. The articulated fuse according to the invention, in which the kinking and triggering of the fuse can take place over the entire length of the guide tube end of the firing pin extension, fully corresponds to today's military conditions. The stabilization foot ensures that the articulated fuse is small in diameter, yet large in its mode of action and the fuse is also easy to manufacture economically. 1. Articulated fuse, in which a kink-sensitive guide tube sits in the fuse housing, in which the Sehlagbolzenyer extension is housed in that with almost the same considerable length of the guide tube (7) and the firing pin extension (6) the firing pin extension (β) made of easily breakable temperature resistant. Made of plastic. 2. Detonator according to claim. 1, characterized in that on the small in diameter The detonator housing (1) is a special, screw-mounted stabilization base made of sheet metal (3) of relatively large diameter to absorb the lever forces, is arranged.
