Definitions
- the invention relates to a train protection for a supply line in a tubular component according to the preamble of patent claim 1.
- the coil has a coating which also encloses the coil-side end of the supply line.
- the production of the coating is comparatively complicated, since the injection mold must have a sealed outlet for the supply line. In production, the coil must be inserted manually into the injection mold and the cable must be led out. In particular, in the conventional injection molds with multiple injection nests this type of production of a train protection is cumbersome. In many cases, the coils are already arranged within a housing in such a way that the coils and the strands never come into contact with a working medium. Consequently, a coating may provide more functionality than required.
- the object of the present invention is to provide an alternative train protection for the supply line.
- the coil main body has a spout for receiving one end of the supply line, wherein the spout is part of a holding connection between the supply line and the coil main body.
- the holding connection is designed as a positive connection.
- a form-locking connection can securely transmit a high tensile force and is comparatively uncritical in terms of manufacturing tolerances of the components.
- the holding connection may be designed as a frictional connection.
- a frictional connection can be realized in many cases with particularly simple components.
- the spout is made in one piece with the coil body. This connection allows very high power transmission.
- the spout can be formed by a separate component. This design facilitates the injection-technical production of the coil main body.
- the grommet is preferably connected by means of a latching connection with the coil main body.
- a locking connection can be closed quickly and reliably and easily checked for correct fit.
- the spout is designed as a clamping cylinder.
- the clamping cylinder is axially slotted and has a number of clamping hooks.
- the force required for mounting the supply line and the production of the holding connection is lower than for an unslotted clamping cylinder.
- the spout has a conductor channel cover. This design simplifies the connection of the supply line with the ends of a winding on the coil body.
- the spout is made in several parts and the individual components form a clamping ring.
- the component limits of the individual parts can be optimized to a production technique by injection molding.
- a retaining ring can be inserted between the spout and the supply line.
- the retaining ring can, for. B. be radially elastic for a frictional connection. In a positive connection, the retaining ring is gripped axially.
- the retaining ring can be secured via a support ring to the supply line.
- a retaining ring in the form of an O-ring can be adjusted on the position of the support ring to the retaining ring, the radial holding force of the retaining ring.
- the spout is supported radially, at least indirectly, on an inner wall of a cable receiver.
- the support can z. B. only after overcoming a certain game but also already under bias. Indirect is to be understood in the sense that z. B. a transfer ring is used.
- the inner wall is formed by a piston rod of a piston-cylinder unit.
- Fig. 1 - 3 force-locking connection between supply line u. Kitchen sink
- FIG. 5-7 variant of FIG. 1 -3 with separate multi-part spout
- Fig. 8 - 1 1 holding connection via nozzle and conductor channel cover Fig. 12 u. 13 variant of Fig. 1 -3 with retaining ring
- FIGS. 14 and 15 Variant to FIGS. 14 and 15
- FIG. 1 shows a detail of a piston-cylinder unit 1, for example an adjustable vibration damper.
- a piston rod 5 is guided axially movable, the u. a. serves as a line receiving 7 for a supply line 9 of an electric coil 1 1.
- the coil 1 1 comprises a coil main body 13 and a winding 15, which is shown only schematically.
- a pot-shaped housing 17 is fixed to the hollow piston rod 5, which receives the coil 1 1.
- the coil 11 can also be arranged directly inside the hollow piston rod 5.
- the coil main body 13 is preferably made of plastic by means of a spraying process and comprises a pipe section 19 for receiving the winding 15 and an end-side closed cover 21. Not shown, coil ends penetrate the cover 21 to a facing in the direction of a housing bottom 23 top surface 25. Individual strands 27 of the supply line 9 are on the top surface 25 and are connected to the coil ends.
- the supply line 9 passes through a spout 29, which is designed in this embodiment as a clamping cylinder 29.
- the clamping cylinder 29 is slotted axially, wherein the slots separate clamping hooks 31 from each other, which are radially elastic and rest on a externa ßeren lateral surface 33 of the supply line 9.
- the clamping cylinder 29 is made in one piece with the coil main body 13, so that the clamping hooks are also made of plastic.
- the clamping hooks 31 have an externa ßere conical clamping surface 35, which cooperate with a transmission ring 37. Also, the transmission ring 37 has a conical surface 39 in the form of a depression.
- the transmission ring 37 is threaded onto the supply line 9. Then leads the end of the supply line 9 in the spout 29 of the coil main body 13 and connects the strands 27 with the ends of the winding 15. The strands 27 are now on the top surface 25 of the coil body 13 and the clamping hooks 31 are under radial bias in Contact with the lateral surface 33 of the supply line 9.
- the transfer ring 37 is pushed with its conical surface 39 on the clamping surfaces 35 of the clamping hooks 31, whereby they deform radially inwardly on the lateral surface 33.
- the open end of the supply line 9 is inserted into the hollow piston rod 5 until the top surface 25 bears against the housing bottom 23.
- the transfer ring 37 rests against an inner shoulder 41 of the hollow piston rod 5.
- FIG. 4 is intended to show that the function of the transmission ring according to FIG. 2 can also be formed by a conical surface of the cable receiver 7.
- FIGS. 5 to 7 likewise describe a variant with a frictional retaining connection between the grommet 29 and the coil main body 13.
- the grommet 29 is formed here by a separate component from the coil main body 13, which in turn is designed in several parts and the individual components form a clamping ring.
- An inner ring 43 as a component of the spout 29 has individual clamping hooks 31 corresponding to FIGS. 1 to 3.
- the inner ring has an annular bottom 45 which determines a stop position on an end face 47 of the supply line 9.
- the bottom 45 has a passage opening 39 for the strands 27.
- a clamping ring 51 as a further component of the grommet 29 has a conical surface 39 corresponding to the transfer ring 37 of Fig. 2 at a pointing in the direction of the top surface 25 of the coil main body 13 end of the clamping ring 51 via radially elastic latching means 53, which engage in a circumferential groove 55 of the top surface 35 above a connecting piece 57 which builds up thereon.
- the assembly of the supply line 9 begins with the threading of the inner ring 43 and the clamping ring 51, wherein the inner ring 43 rests against the end face 47 of the supply line 9. Thereafter, the wiring of the supply line 9 is carried out with the winding 15. Furthermore, the clamping ring 51 is pushed with its conical surface 39 on the clamping surface 35 of the clamping hook 31 on the inner ring 43, whereby a non-positive holding connection between the supply line 9 and the spout 29 is constructed. After that, the clamping ring 51 with its latching means 53 is pressed into the coil main body 13 in order to close the form-locking connection with the coil main body 13. The open end of the supply line can now be inserted into the hollow piston rod 5 in order to achieve the mounting state according to FIG. 5.
- the embodiment of Figures 8 to 1 1 differs from the two previous designs in that the grommet 29 has only a single slot 30 in the simplest design.
- the grommet 29 has a cover of the lateral surface 33 of more than 180 °, so that an equator of the supply line 9 is encompassed.
- the grommet 29 connects at a right angle to a conductor channel cover 59, which is preferably fixed on the top surface 25 of the coil main body 13 by means of a latching connection 61.
- the inner diameter of the nozzle 29 is slightly smaller than the outer diameter of the supply line 9.
- the slot 30 ensures a tolerance compensation in the press fit. In this region of the spout 29 is between the supply line 9 and the spout 29 before a frictional holding connection.
- the individual strands are bent essentially at right angles to the longitudinal axis of the piston rod 5.
- the conductor channel cover 59 fixes the individual strands 27 on the top surface 25 of the coil base body 13.
- the supply line 9 is inserted into the grommet 29.
- the strands 27 are bent over and connected to the ends of the winding 15. Then pushes the conductor channel cover 59 together with the grommet 29 again in the direction of the top surface 25 and closes the latching connection between the conductor channel cover 59 and the coil body 13.
- latching hooks 63 are visible, which engage in the coil body 13.
- FIGS. 12 and 13 describe a further development of the variant according to FIGS. 8 to 11.
- the holding connection has a retaining ring 65, which is formed in this illustration by an O-ring.
- a slot according to FIG. 9 is therefore no longer necessary.
- the O-ring 65 provides a press fit between the inner diameter of the spout 29 and the lateral surface 33 of the supply line 9.
- a support ring 67 can be used, over which the bias of the retaining ring 65 is adjustable by the support ring 67 more or less deep in the spout 29 is pressed. A comparable effect can be achieved if the retaining ring 65 is supported directly on a shoulder 69 of the hollow piston rod.
- Figures 14 and 15 describe a variant in which a holding connection between the supply line 9 and the coil base body 13 is to be achieved via a positive connection.
- the supply line 9 has a thickening 71 which is optionally formed by a partially reinforced casing or, as shown in FIG. 16, by a separate holding ring 73.
- the spout 29 has the at least one slot 30, which allows a radial mounting of the supply line in the spout 29, but also covers more than 180 ° of the lateral surface 33.
- the grommet 29 has an annular groove 75 for receiving the thickening 71.
- the spout 29 can expand radially within limits.
- the thickening 71 snaps into the annular groove 75.
- the embodiment according to FIGS. 16 and 17 is identical to the embodiment according to FIG. 14.
- the grommet 29 is made in one piece with the coil base body 13 and the thickening for the form-locking connection is formed by the separate retaining ring 73, which is radial is elastic and possibly engages in a groove 79 of the lateral surface 33.
