Abstract
Description
Technical Field
[0001] The present invention relates to an arrangement system according to the preamble features of claim 1, the arrangement system comprising a cable secured to a base by at least one fixing device. Background Technology
[0002] Such arrangement systems are known, in which, for example, a plug connector is provided at each of the two ends of the cable, which is secured to a base by fastening devices. The fastening devices can be, for example, cable ties of the same or different types. The base can be, for example, a vehicle body panel, particularly for electric vehicles.
[0003] While cable ties can permanently secure cables to the base, there is a risk that the ties may come loose or the cable may rub against the area around the ties. This could expose the cable's electrical conductors, making them accessible, especially dangerous in electric vehicles with high-voltage cables, such as those operating at 400 or even 800 volts, and must be absolutely avoided. Summary of the Invention
[0004] Therefore, the object of the present invention is to improve a similar arrangement system so that, on the one hand, the cable can be reliably and permanently fixed to the base, while on the other hand, simple and flexible installation can be achieved.
[0005] This objective is achieved by the features of claim 1.
[0006] According to the present invention, the fixing device is designed as a half-shell, the half-shell having a fixing piece extending therefrom, wherein the fixing piece has a through hole for fixing the half-shell, and a protrusion extends from the fixing piece, the protrusion being connected to the base when the fixing device is set and fixed in its mounting position as specified.
[0007] In an improved embodiment of the invention, the fixing piece is provided with an elongated hole, which serves as a through-hole for fixing the half-shell. The elongated hole allows the half-shell to be adapted to the routing of the cable on the base, where the cable should be fixed. Attached Figure Description
[0008] The following describes a known arrangement system in the prior art and two embodiments of the arrangement system of the present invention, with reference to the accompanying drawings. Detailed Implementation
[0009] Figure 1The diagram illustrates a prior art arrangement system as described in the background section above. This system includes a cable 1, with plug connectors 2 and 3 at each end. The cable 1 is secured to a first portion of a base 5 using a first cable tie 4. An additional securing device, a separate cable tie 6, with a different structure from cable tie 4, is provided to secure the cable 1 to another portion of a base 7. In this known prior art, although the cable 1 can be reliably and permanently secured to the respective bases 5 and 7, the outer sheath of the cable 1 may wear down due to factors such as vibration and temperature changes, thereby exposing the electrical conductors inside the outer sheath. Figure 1 The cables in the arrangement system shown are high-voltage cables, capable of transmitting voltages of 400 volts or 800 volts. Therefore, it is essential to absolutely avoid wear on the outer sheath of cable 1 caused by securing it firmly with cable ties 4 and 6.
[0010] Figure 2 A first embodiment of an improved fixation of cable 1 on its base according to the present invention is shown. As a fixing device for fixing cable 1, for example, to base 5, a half-shell 8 is provided. A fixing piece 9 extends from half-shell 8, having an opening for a fixing element to pass through, the internal geometry of the half-shell roughly or completely corresponding to the external geometry of cable 1. In this case, the fixing element is designed as a nut 10. This means that a threaded pin extends from the surface of base 5. The fixing piece 9 is fitted onto the threaded pin, while cable 1 is placed within the area of half-shell 8 and the nut 10 is screwed onto the free end of the threaded pin. In this way, cable 1 is fixed to base 5 by means of half-shell 8 as required. To prevent the fixing piece 8 from rotating during the fixing process due to fitting and tightening the nut 10 (which could also damage the outer sheath of cable 1), a protrusion 11 extends from the fixing piece 9 (or, alternatively or supplementally, from half-shell 8). Protrusion 11 has a pin-shaped end that inserts into a hole in base 5. This effectively prevents the retaining plate 9 from rotating when the nut 10 is tightened. Furthermore, it has the advantage that the nut 10 can be tightened with a single, simple tool, without the need for additional tools. The fastening device consists of a half-shell 8, a retaining plate 9 with a through hole, and a protrusion 11. This fastening device is made of metal, but can also be made of plastic, for example, through injection molding. In addition to the nut 10 and the threaded pin extending from the base 5, a screw can also be considered, passing through a hole in the retaining plate 9 and engaging with a hole in the base 10. For example, such a screw could be a self-tapping screw. Using a nut or screw, the commonly known rotational fastening method, has the advantages of a reliable and recordable installation process.
[0011] Figure 3 It shows the Figure 2 A further improvement to the arrangement system is that the hole (through hole) in the fixing piece 9 is designed as an elongated hole 12. This allows for optimized adjustment of the position of the half-shell 8 on the cable 1 according to the routing or position of the cable 1 on the base 5.
[0012] The choice of the elongated bushing (i.e., the retaining plate 9 with the elongated hole 12) is also to minimize the forces that may be generated by installation tolerances and act on the retaining device (also known as the threaded connector).
[0013] exist Figure 3 In the lower left and lower right views, it can be clearly seen that the pin-shaped protrusion 11 is embedded in the corresponding hole in the base to prevent the half-shell 8 from rotating when it is secured by the nut 10 (or other type of fixing element). Here, the hole in the base (in which the pin-shaped protrusion 11 is embedded) can also be designed as an elongated hole (or alternatively as a round hole).
[0014] The fixing device includes a half-shell 8, a fixing plate 9, and through holes (circular or elongated) and protrusions 12 for fixing the component. The interior of the fixing device may be made of metal material covered with plastic, preferably by injection molding. The internal metal material provides the necessary stability, while the external plastic covering effectively prevents wear on the outer sheath of the cable 1. Preferably, the entire fixing device is made of metal material, with only the half-shell 8 covered with plastic.
