Clamping parts

Abstract

To efficiently arrange the filter core of an EMC filter in a limited space such as a vehicle. [Solution] In a clamping component for fixing a wire harness to another component, the holding portion for holding the wire harness is made of resin and is configured to be divided into two parts so that it forms a ring when holding the wire harness, and the filter core of the EMC filter is divided into two parts and built in. This allows the clamping component for the wire harness to function as both the filter core of the EMC filter and the clamping component for the wire harness, and allows the filter core of the EMC filter to be efficiently arranged in a limited space such as a vehicle.

Description

[Technical Field]

[0001] The present disclosure relates to a clamping component, and more particularly to a clamping component for fixing a wire harness to another member. [Background technology]

[0002] A conventional technique of this type is a wire harness in which the outer periphery of the electric wires exposed from through holes on both sides of the electromagnetic wave absorbing component exposed from the tubular member is brought into contact with the outer periphery of a braided shield (see, for example, Patent Document 1). This technique reduces electromagnetic noise while suppressing wear of the braided shield by providing a braided shield that covers the electric wires. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-178861 Summary of the Invention [Problem to be solved by the invention]

[0004] Components that involve switching, including inverters, are becoming increasingly high current and voltage, which is resulting in an increase in the amount of electromagnetic noise they generate. The EMC filters required to eliminate this noise are also becoming larger. This makes it difficult to find a way to install larger EMC filters in a limited space, such as in a vehicle.

[0005] The clamping component of the present disclosure is primarily intended to efficiently arrange the filter core of an EMC filter in a limited space such as a vehicle. [Means for solving the problem]

[0006] The clamping component of the present disclosure employs the following means to achieve the above-mentioned main object.

[0007] The clamping components of the present disclosure include: A clamp component for fixing a wire harness to another member, The holding portion that holds the wire harness is made of resin, is divided into two parts so as to form a ring shape when holding the wire harness, and has a divided filter core of an EMC filter built-in. It is characterized by:

[0008] In the clamp component of the present disclosure, the holding portion that holds the wire harness is made of resin and is divided into two parts so as to form a ring when holding the wire harness, and the filter core of the EMC filter is divided and built in. Therefore, since the filter core is built into the clamp component that clamps the wire harness to another member, it is possible to efficiently arrange the filter core of the EMC filter in a limited space such as a vehicle.

[0009] In the clamp member of the present disclosure, it is preferable that it has a clip for fixing to a hole formed in another member, and it is also preferable that it has a plurality of protrusions on the inside of the holding portion for fixing the wire harness. [Brief explanation of the drawings]

[0010] [Figure 1] 1 is a diagram showing an outline of the configuration of a clamping component 20 according to an embodiment of the present disclosure. [Figure 2] 1 is an explanatory diagram illustrating a state in which a wire harness 10 is attached and fixed to another member 12 using a clamp component 20 of the embodiment. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0011] Next, a mode (embodiment) for carrying out the present disclosure will be described. Fig. 1 is a diagram showing an outline of the configuration of a clamping component 20 according to one embodiment of the present disclosure. Fig. 2 is an explanatory diagram showing a state in which a wire harness 10 is attached and fixed to another member 12 using the clamping component 20 according to the embodiment.

[0012] The clamp member 20 of the embodiment includes a first semi-tubular member 22a formed from resin in a semi-tubular shape, a second semi-tubular member 22b similarly formed in a semi-tubular shape, and a joint 23 joining the first semi-tubular member 22a and the second semi-tubular member 22b so that the overall member becomes a short tubular member when the wire harness 10 is attached to another member 12.

[0013] The first and second semi-tubular members 22a and 22b each have a semi-tubular shape made of a magnetic material and are fitted inside the first and second semi-tubular members 22a and 22b to form the filter cores of the EMC filter when the wire harness 10 is attached to another member 12.

[0014] A clip 25 is attached near the center of the outside of the first semi-tubular member 22a to be inserted into a hole in the other member 12. A male convex portion 24b for assembling with the first semi-tubular member 22a is formed in the center of the opposite side of the joint portion 23 of the semi-tubular cut surface of the second semi-tubular member 22b, and a female concave portion 24a into which the male convex portion 24b can be fitted is formed at a position that matches the male convex portion 24b of the first semi-tubular member 22a.

[0015] 1, the clamp component 20 of the embodiment is attached to the wire harness 10 by engaging the male convex portion 24b with the female concave portion 24a so as to sandwich the wire harness 10, and the clip 25 formed on the first semi-tubular member 22a of the clamp component 20 is inserted into a hole (not shown) in the other member 12, thereby clamping the wire harness 10 to the other member 12. This state is shown in FIG.

[0016] As described above, in the embodiment, the filter core of the EMC filter is divided into the first core member 30a and the second core member 30b, and these are housed in the first semi-tubular member 22a and the second semi-tubular member 22b that constitute the clamping component 20. Then, the wire harness 10 is clamped to the other component 12 by the clamping component 20. This allows the filter core of the EMC filter to be efficiently arranged in a limited space such as a vehicle.

[0017] The correspondence between the main elements of the embodiments and the main elements of the invention described in the "Means for Solving the Problem" section does not limit the elements of the invention described in the "Means for Solving the Problem" section, since the embodiments are examples for specifically explaining the mode for implementing the invention described in the "Means for Solving the Problem" section. In other words, the interpretation of the invention described in the "Means for Solving the Problem" section should be based on the description in that section, and the embodiments are merely specific examples of the invention described in the "Means for Solving the Problem" section.
