In this exemplary filter circuit 10, two noise reduction elements 11 are covered with an insulating molded body 14 (FIGS. 1 to 6). The mold body 14 is a solidified molding agent injected between the two noise reduction elements 11, the first wall 12a of the first circuit connection member 12, and the first wall 13a of the second circuit connection member 13. It also covers the connection between the two noise reduction elements 11 and the first wall 12a and the connection between the two noise reduction elements 11 and the first wall 13a.

Alternatively, the intermediate connection portion WEa1 arranged on the side opposite to the noise reduction element 11 with respect to the second wall 12b may be electrically connected to the second wall 12b indirectly or directly. Here, the former is exemplified.

A second wall 12b of the first circuit connection member 12 is provided with a contact 12c for indirectly or directly electrically connecting the intermediate connection portion WEa1 (FIGS. 1 to 6).

(Figures 4 to 6). In the second wall body 13b, the extruded portion becomes a contact point 13c having elasticity. The contact 13c has an abutment surface _13c1 with which the intermediate connection portion WEa2 of the second electric wire WE2 abuts indirectly or directly (FIGS. 5 and 6). The illustrated contact 13c is formed with _a rectangular contact surface 13c1. Also, the contact 13c may have an engaging portion 13c2 to which the intermediate connection portion WEa2 of the _second electric wire WE2 is indirectly or directly engaged (FIG. 8). In the engaging portion _13c2 , for example, part of the outer peripheral surface of the intermediate connection portion WEa2 or part of the outer peripheral surface of the second wire-side connector 33, which will be described later, enters and is engaged. The locking portion _13c2 is, for example, a peripheral portion of a groove or a peripheral portion of a through hole into which a portion of the outer peripheral surface of the intermediate connection portion WEa2 or a portion of the outer peripheral surface of the second wire-side connector 33 enters.

It has an inclined surface 32a that indirectly or directly applies a second pressing force to the connecting portion WEa2 (FIG. 6). The inclined surface 32a comes into direct or indirect contact with the intermediate connection portion WEa2 as the assembly of the cover 42 to the storage box 41 progresses, and the intermediate connection portion WEa2 contacts the intermediate connection portion WEa2 as the assembly progresses. Indirectly or directly, the second pressing force is applied. The second pressing body 32 applies the second pressing force from the inclined surface 32a to the intermediate connection portion WEa2 indirectly or directly when the cover 42 and the housing box 41 are in the assembled state. leave.

As shown in FIG.

The illustrated first wire-side connector 23 is made of a conductive material such as metal.

The noise filter 1 of this embodiment shown above is not affected by the intermediate electric wire. In other words, in the conventional noise filter, as described above, the intermediate wire is interposed between the noise reduction target wire and the filter circuit. The intermediate electric wire has a large length tolerance in consideration of assembling workability to the noise filter, wiring route to the vehicle, and the like. Therefore, in the conventional noise filter, it is necessary to adjust the filter circuit characteristics (resonance point, noise reduction performance, etc.) in consideration of the noise component of the intermediate wire according to its length. However, in the noise filter 1 of the present embodiment, the filter circuit 10 is provided between the intermediate connection portion WEa1 of the first electric wire WE1 and the intermediate connection portion WEa2 of the second electric wire WE2 bundled with the main line WT of the wire harness WH. The filter circuit 10 is electrically connected to the respective intermediate connection portions WEa1 and WEa2. Therefore, the noise filter 1 does not require adjustment of the filter circuit characteristics in consideration of the influence of branch wires (intermediate wires) from the main line as in the conventional art. That is, this noise filter 1 is not affected by the intermediate electric wire.

Further, in the noise filter 1 of the present embodiment, the noise reduction element 11, the contact 21 (12c) of the first circuit connection member 12, the contact 31 (13c) of the second circuit connection member 13, and the intermediate connection portion of the first wire WE1 Since the WEa1 and the intermediate connection portions WEa2 of the second electric wires WE2 are arranged in a row, stacking of these arrayed components is avoided in the direction orthogonal to the direction of arrangement and the axial direction of the respective intermediate connection portions WEa1 and WEa2. can do. Therefore, the noise filter 1 of this embodiment can be miniaturized in the orthogonal direction.

Furthermore, in the noise filter 1 of this embodiment, the first pressing body 22 of the first electrical connection structure 20 and the second pressing body 32 of the second electrical connection structure 30 are each formed in a wedge shape. For this reason, in the noise filter 1, when the housing box 41 and the cover 42 are assembled, the first pressing body 22 is pushed from the sharp edge side of the tip to the noise reduction element 11 and the intermediate connection portion WEa1 (or the first electric wire side). connecting body 23), and the second pressing body 32 is inserted between the noise reduction element 11 and the intermediate connecting part WEa2 (or the second wire side connecting body 33) from the sharp edge side of the tip. is inserted into Therefore, the first pressing body 22 does not allow the noise reduction element 11 and the intermediate connection part WEa1 (or the first wire side connection body 23) to come into contact when the insertion from the distal end side is started, and the insertion of the first pressing body 22 is possible. The inclined surface 22a may be formed so as to come into contact with the intermediate connection portion WEa1 (or the first wire-side connector 23) after progressing to some extent (for example, half or more). In other words, the first pressing body 22 may be formed so as not to receive the reaction force from the intermediate connecting portion WEa1 (or the first wire-side connecting body 23) when the insertion from the distal end side is started. Similarly, the second pressing body 32 does not touch the noise reduction element 11 and the intermediate connection part WEa2 (or the second wire side connection body 33) when the insertion from the tip side is started, and the insertion of the second pressing body 32 is prevented. has progressed to a certain extent (for example, more than half), the inclined surface 32a is formed so as to touch the intermediate connection portion WEa2 (or the second wire side connector 33), and when insertion from the tip side starts, It may be formed so as not to receive the reaction force from the intermediate connection portion WEa2 (or the second wire side connector 33). In the noise filter 1 of the present embodiment, by forming the first pressing body 22 and the second pressing body 32 in such a shape, positioning between the housing box 41 and the cover 42 when starting to assemble them is possible. Since this becomes easy and no unnecessary force acts when the assembly of the storage box 41 and the cover 42 is started, the workability of assembling the storage box 41 and the cover 42 can be improved.

Furthermore, in the noise filter 1 of the present embodiment, the filter circuit 10 is electrically connected to the intermediate connection portion WEa2 of the second electric wire WE2, one end of which is grounded. Even if there is no possible conductor, and even if the object to be installed is made of an insulating material such as synthetic resin, it can be easily grounded. In other words, the conventional noise filter is grounded via the installation object by connecting a ground terminal to the installation object when attached to the installation object. Therefore, in the conventional noise filter, the ground terminal protrudes from the housing in order to facilitate the work of fixing the ground terminal to the object to be installed. However, this noise filter 1 can be grounded without having such a ground terminal. Therefore, the noise filter 1 can be reduced in size and weight.

Furthermore, in the noise filter 1 of the present embodiment, the contact 21 (12c) of the first circuit connection member 12 and the first pressing body 22 indirectly or directly sandwich the intermediate connection portion WEa1 of the first electric wire WE1, In addition, the contact 31 (13c) of the second circuit connection member 13 and the second pressing body 32 indirectly or directly sandwich the intermediate connection portion WEa2 of the second electric wire WE2. Therefore, in this noise filter 1, the first electrical connection structure 20 and the second electrical connection structure 30 are different from the conventional one in which the electrical connection structure is a fitting structure of male and female terminal portions. Miniaturization becomes possible. Therefore, the noise filter 1 can be downsized. In addition, although such a conventional connection structure may lead to an increase in cost depending on the shape, this noise filter 1 can suppress an increase in cost because of such a simple connection structure.

Furthermore, the noise filter 1 of this embodiment employs the first electrical connection structure 20 and the second electrical connection structure 30 of such connection structures, and the respective contacts 21 (12c) and 31 (13c) By imparting elasticity to , it is possible to absorb the dimensional variations of the respective component parts and apply a stable contact load to the respective intermediate connection portions WEa1 and WEa2. In addition, in this noise filter 1, by giving flexibility to the first pressing body 22 and the second pressing body 32, together with the elasticity of the respective contacts 21 (12c) and 31 (13c), Even if the dimensional variation of each component becomes larger, the dimensional variation can be absorbed and a stable contact load can be applied to each of the intermediate connection portions WEa1 and WEa2. Due to such characteristics, the noise filter 1 can improve the quality of current flow between the first electric wire WE1 and the second electric wire WE2 and the filter circuit 10 .

Furthermore, the noise filter 1 is configured such that the contacts 21 (12c) and 31 (13c) are elastic, so that the electric wires (the first electric wire WE1, the second electric wire WE1, the 2 electrical connection can be made to the electric wire WE2). In addition, when the first pressing body 22 and the second pressing body 32 are made flexible, the noise filter 1 can accommodate electric wires of various outer diameters (first Electrical connection can be achieved with respect to the electric wire WE1 and the second electric wire WE2). That is, the noise filter 1 can be applied to electric wires (the first electric wire WE1 and the second electric wire WE2) with various outer diameters, and can improve versatility.

Moreover, the wire harness WH of the present embodiment is provided with such a noise filter 1, and the effect of obtaining this noise filter 1 can be achieved.
