Definitions
- the invention relates to a vacuum cleaner hose with electrical conductors according to the preamble of claim 1.
- the carrier is in this case introduced by a spraying process thermoplastic material connected to the hose.
- the end bush is fixed in the hose. That for fixing the carrier on the hose and material used to fasten the end bushing in the hose is either the same or similar to the hose material, so that those made with it Connections serve their purpose. The connections cannot be non-destructive be solved.
- the spraying process is complex, requires specialists and special Implementation facilities.
- the object of the invention is the vacuum cleaner hose according to the preamble of Claim 1 form so that for the connection of the carrier and the end bush a spraying process with the hose is not necessary.
- the connection of the carrier and the end bushing with the hose should be designed so that it is taught by Forces are deployed without great aids and can be released again if necessary can.
- the object is achieved by the in the characterizing part of Claim 1 specified training solved.
- 1 is an existing one made of a soft thermoplastic Designated hose, the outer helical troughs 1a and Has wave crests 1b.
- hose 1 On the hose 1 is made of a harder plastic than the hose Carrier for electrical slip rings 3 attached. There is one on each of the slip rings 3 electrical conductor 4 connected. The conductors 4 are in the hose 1 on one arranged below described in more detail.
- the carrier is made up of two parts. One part is a socket ring 2a, the with is equipped with a slip ring 3 and has an all-round closed jacket. The other part consists of a sleeve 2b arranged in front of the bushing ring 2a is equipped with two further slip rings 3. The sleeve 2b has a continuous Axial slot 6 on.
- At least one thread 7 is formed on the inner lateral surface of the sleeve 2b, which has a mating thread for the wave troughs 1a and wave crests 1b of the hose 1 forms.
- the sleeve 2b is screwed onto the hose 1 after the sleeve ring 2a is pushed onto the hose 1.
- the ends of the electrical conductors 4 are arranged in a tube 1 Protective cover 8 first in the axial slot 6 of the sleeve 2b and then to the assigned slip rings 3, which are exposed in the axial slot 6 inside.
- the bushing ring 2a is positively connected to the sleeve 2b.
- For positive Connection engages a circumferential outer bead formed on the socket ring 2a 2c into a corresponding inner groove 2d of the sleeve 2b (FIG. 1).
- FIG. 1 As a further embodiment of the invention is in the end bushing 5 from its rear End extending slot 5b extending to the bead ring 5a (Fig. 1) intended.
- the flanks of the slot 5b go into a tubular projection 5d over, which is provided for receiving the associated end of the protective cover 8.
- the projection 5d is open at the open end of the slot 5b and at the opposite Closed at the end.
- the slot 5b is preferred in its intended position aligned so that it is aligned with the axial slot 6 of the sleeve 2b. In this way there is a bending path for the electrical conductors 4, as can be seen from FIG. 1.
- an expedient further development of the subject matter of the invention consists in that a molded joint 2f, the sleeve 2b in two identical shell halves 2g divides, the free edges of which are the flanks of the axial slot 6.
- This is the sleeve 2b, as shown in Fig. 4, in an unfolded form, for which a simple slide-free shape is sufficient.
- the two shell halves 2g against each other around the joint 2f to move until the shape shown in Fig. 3 results.
