Thus, it is possible to suppress the deformation of the ferrite 8.In addition, the pressure to be applied to each of the ferrite 8 can be reduced compared to a case in which a plurality of ferrites are integrally molded. Thus, it is possible to suppress the deformation of the ferrite 8. Furthermore, according to the embodiment of the invention, since the projections 92 of the pair of pressing arms 9 press the four corners 8a, 8b, 8c, 8d of each of the ferrites 8, the deformation of ferrite 8 can be minimized. Thus, it is possible to suppress the deterioration of the noise removal capacity of each ferrite 8.
    According to the embodiment of the invention, when each of the ferrites 8 is being mounted between the pair of pressing arms 9, the pair of beams 44 and the plurality of vertical walls 43 are interconnected to prevent deformation of the pair of beams 44.
    Next, a process for assembling connector 1 will be explained. First, in a state where the first housing 3 and the second housing 4 are separated from each other, the two conductors 5 are inserted into the insertion grooves 42 of the second housing 4. Then, the terminals 6, which protrude from the upper surface 41 of the conductor fixing portion 40, they are passed through the through holes 80 of the respective ferrites 8, and each of the ferrites is mounted between the pair of a respective pressing arm 9. Next, the second housing 4, which contains the two conductors 5 and the plurality of ferrites 8 is inserted into the container of the first housing 3, and the pair of locking portions 49 are attached to a pair of locking receiving portions 37. Thus, the second housing 4 it is mounted for the first housing 3. In this way, the assembly of the housing 1 is completed.
    In the following, a connector according to another embodiment of the present invention will be explained with reference to fig. 12 to fig. 16. In fig. 12 to fig. 16, the same constituent elements as those of connector 1, as described in the embodiment, are given the same reference numbers, and their detailed description is omitted. The connector according to the other embodiment includes a housing, the two conductors 5 and the plurality of ferrites 8 that remove the noise generated from the plurality of terminals 6 provided in the conductors 5. The housing includes the first housing 3 (illustration is omitted , but it has the same structure as that of the first housing 3 of the connector 1) and a second housing 104, which is made of a synthetic resin.
    As shown in fig. 12 to fig. 14, the second housing 104 includes a conductor fixing portion 40 formed in a rectangular shape, a pair of locking portions 49 provided on opposite sides of the conductor fixing portion 40, a frame 143 extending from the upper surface 41 the conductor fixing portion 40 in the form of a square tube, and a plurality of press fit portions 109 having a plurality of ferrites 8. Each of the plurality of press fit portions 109 extends from the upper surface 41 of the conductor fixing portion 40 in columnar shape. Four of the press fit portions 109 are provided for each of the ferrites 8. The four press fit portions 109 are arranged so that portions of the press fit portions 109 contact the four corners 8a, 8b, 8c, 8d of each of the ferrites 8, respectively. That is, each of the ferrites 8 is press-fit between the four adjustment portions 109, so as to elastically deform the four press adjustment portions 109 outwardly. The press adjustment width h1 in figure 15 and the press adjustment height h2 in figure 16 of each of the ferrites 8 are determined, insofar as the functional degradation of the ferrite 8 does not occur.
    In this way, according to the connector of the other modality, since the four press adjustment portions 109 fasten each of the ferrites 8 elastically by contact with the four corners 8a, 8b, 8c, 8d of each of the ferrites 8, the pressure to be applied to each ferrite 8 can be reduced compared to a case where a ferrite is inserted molded into the housing. Thus, it is possible to suppress the deformation of the ferrite 8. Furthermore, the pressure to be applied to each of the ferrites 8 can be reduced compared to a case in which a plurality of ferrites are integrally molded. Thus, it is possible to suppress the deformation of the ferrite 8. Thus, it is possible to suppress the deterioration of the noise removal capacity of each ferrite 8.
    The modalities described above are presented as representative forms of the present invention, and the present invention is not limited to the modalities. That is, the invention can be implemented by various modifications without departing from the essence of the present invention.
