Abstract
Description
[Technical field]
[0001] The present disclosure relates to a cable fixing structure that enables resonance point tuning applied to a vehicle. [Background technology]
[0002] Patent Document 1 discloses a cable fixing structure in which a noise countermeasure is implemented by fixing a cable to a cable gland via a ferrite core. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2002-171612 A Summary of the Invention [Problem to be solved by the invention]
[0004] When adjusting the noise countermeasures in the cable fixing structure disclosed in Patent Document 1, it is necessary to remove the cable to replace the ferrite core and then refix the cable to the new ferrite core, which poses the problem that the adjustment work for noise countermeasures is cumbersome.
[0005] The present disclosure has been made in consideration of the above-mentioned problems, and aims to provide a cable fixing structure that allows adjustment of noise countermeasures without having to re-fix the cable each time. [Means for solving the problem]
[0006] In order to solve the above problems, one aspect of the disclosed technology is a cable fixing structure for use in a vehicle, comprising: a main body component for fixing the cable; and an adjustment component having an electronic component for adjusting the impedance of the vehicle, wherein the main body component comprises a first mounting portion having a through hole for inserting the cable, a metal collar that fits into the first mounting portion, a second mounting portion which allows the adjustment component to be inserted and removed, and a connection circuit that electrically connects the metal collar and the electronic component, wherein the cable is fixed to the first mounting portion via the metal collar, and the adjustment component is attached to the second mounting portion. Effect of the Invention
[0007] According to the cable fixing structure of the present disclosure, noise countermeasures can be adjusted simply by inserting and removing adjustment parts without removing the cable, thereby reducing the hassle of adjustment work for noise countermeasures. [Brief description of the drawings]
[0008] [Figure 1] FIG. 1 is a top view illustrating a structure of a main body part used in a cable fixing structure according to an embodiment of the present disclosure. [Diagram 2] AA cross-sectional view of the main body part shown in FIG. [Diagram 3] FIG. 1 shows an example of an adjustment part. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] The cable fixing structure according to the present disclosure includes a structure that allows an adjustment part that can adjust the impedance of the vehicle to be inserted and removed from the part that fastens the cable to the vehicle body GND. This structure allows the noise countermeasures to be adjusted simply by changing the adjustment part. Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings.
[0010] <Embodiment> [structure] Fig. 1 is a top view for explaining the structure of a main body component 100 used in a cable fixing structure according to an embodiment of the present disclosure. Fig. 2 is a cross-sectional view taken along line AA of the main body component 100 shown in Fig. 1.
[0011] 1 and 2 is a part (connection part) for fastening a cable (not shown) to the body GND of a vehicle. An example of the cable is a wire harness (W / H) used for wiring in a vehicle. This main body part 100 includes a first attachment part 110, a metal collar 120, a second attachment part 130, and a connection circuit 140.
[0012] The first attachment portion 110 is provided for attaching a wire harness (W / H) to the main body component 100, and is a hole penetrating the main body component 100 for inserting the wire harness (W / H).
[0013] The metal collar 120 is a cylindrical part made of a conductive metal material. The cylindrical shape of the metal collar 120 allows the metal collar 120 to be fitted into the through hole of the first mounting portion 110, and allows a wire harness (W / H) to be inserted inside the metal collar 120.
[0014] With these components, the wire harness (W / H) is inserted into the first mounting portion 110 into which the metal collar 120 is fitted, and is fastened together with the vehicle body GND by the metal collar 120, thereby being fixed to the main body component 100.
[0015] The second mounting portion 130 is provided for attaching a predetermined part in a removable manner, and is typically a socket. An example of the predetermined part is an adjustment part capable of adjusting the impedance of the vehicle and taking measures against noise.
[0016] The adjustment component capable of adjusting the impedance of the vehicle attached to the second attachment portion 130 may be a component having a low fuse size. Such a component having a low fuse size may be realized by replacing the fuse portion 210 in the low fuse component (adjustment component) 200 with a substrate (electronic component) on which elements such as a coil, a capacitor, and a resistor can be directly mounted, as illustrated in FIG.
[0017] In this embodiment, the case where the main body component 100 has two second mounting portions 130 has been described, but the number of second mounting portions 130 may be one or three or more.
[0018] The connection circuit 140 is a component for electrically connecting the second mounting portion 130 to the metal collar 120. When a plurality of second mounting portions 130 are provided on the main body component 100, the connection circuit 140 may be a parallel circuit that connects the plurality of second mounting portions 130 (i.e., the adjustment components 200) and the metal collar 120 in parallel, or may be a series circuit that connects the plurality of second mounting portions 130 (i.e., the adjustment components 200) and the metal collar 120 in series.
[0019] <Effects> As described above, according to the cable fixing structure of one embodiment of the present disclosure, the main body component 100 to which the wire harness (W / H) is fastened and fixed to the vehicle body GND by the metal collar 120 is provided with a socket into which the adjustment component 200 capable of noise countermeasures to adjust the impedance of the vehicle can be inserted and removed.
[0020] This cable fixing structure ensures that the resonant frequencies of the assembled parts match due to differences in impedance between vehicles, and in cases where it is necessary to shift the resonant frequency to comply with EMC (Electro-Magnetic Compatibility), impedance tuning can be easily performed by simply changing the adjustment parts. [Industrial Applicability]
[0021] The cable fixing structure of the present disclosure can be used in cases where it is necessary to shift the resonance frequency of assembled parts for EMC compliance. [Explanation of symbols]
