The first core member 50 has contact surfaces 51A and 51B and a recessed surface 52. Similarly, the second core member 60 has contact surfaces 61A and 61B and a recessed surface 62. . In the coupled state, the contact surfaces 51A and 51B of the first core member 50 are in surface contact with the contact surfaces 61A and 61B of the second core member 60, respectively. At this time, the recessed surface 52 of the first core member 50 and the recessed surface 62 of the second core member 60 form a through hole 3a through which the power line 80 is inserted. Therefore, the split core 3 has a substantially cylindrical shape or a tubular body in the coupled state. At this time, the pair of power line holes 2a and 2b (FIG. 1) formed in the split-type case 2 are positioned near both opening ends of the through-holes 3a formed in the split-type core 3, and the power lines 80 are It penetrates.

Must be in close contact with each other. In order to realize such a close contact state, the split case 2 and the split core 3 have the following structure.

  As shown in FIGS. 4 to 6, the first case member 10 and the second case member 20 include a pair of first pressing portions 12 and a pair of second pressing portions 22. The pair of first pressing portions 12 and the pair of second pressing portions 22 are formed at positions facing each other across the core housing portions 16 and 26 in the coupled state (FIG. 1). The pair of first pressing portions 12 is formed by forming a pair of U-shaped slits 12h (FIG. 4) near the center of the outer peripheral wall 10A. Each first pressing portion 12 is formed with a pressing surface 12 a for contacting and pressing the first core member 50. As shown in FIGS. 5 and 6, each first pressing portion 12 is formed such that the pressing surface 12 a protrudes from the outer peripheral wall 10 </ b> A toward the first core housing portion 16 by a predetermined height. Although the pair of first pressing portions 12 has been described above, the pair of second pressing portions 22 formed on the second case member 20 has the same structure.

  On the other hand, in FIG. 3, the contact surfaces 51 </ b> A and 51 </ b> B of the first core member 50 are located at a slightly higher position (+ Z direction) than the coupling surface 10 j of the first case member 10. That is, the contact surfaces 51A and 51B are not at the same height as the coupling surface 10j, but protrude by a predetermined height with respect to the coupling surface 10j. Similarly, the contact surfaces 61A and 61B of the second core member 60 protrude from the coupling surface 20j of the second case member 20 by a predetermined height.

  According to such a configuration, when the first case member 10 and the second case member 20 are to be closed (combined), the contact surfaces 51A and 51B and the contact surfaces 61A and 61B are combined by the protruding amount. It contacts before 10j and 20j. Then, when the first case member 10 and the second case member 20 are closed (coupled) until the coupling surface 10j and the coupling surface 20j come into contact with or approach each other, the first core member 50 and the second core member 60 are The pair of first pressing portions 12 and the pair of second pressing portions 22 are pressed toward the outer side in the radial direction of the core. Conversely, the pair of first pressing portions 12 and the pair of second pressing portions 22 are respectively in directions in which the first core member 50 and the second core member 60 are pressed against each other (inward in the radial direction of the core). Press. Therefore, a predetermined surface contact, that is, a close contact state is maintained between the contact surfaces 51A and 51B and the contact surfaces 61A and 61B. Therefore, the split core 3 can sufficiently exhibit the characteristics as a magnetic core.

  Next, as shown in FIGS. 3 and 4, a case locking piece 15 is provided on the first case member 10. The second case member 20 is formed with a case locking hole 20c (FIG. 4).

  As shown in FIGS. 3 and 4, a band holding portion 18 is provided in the vicinity of the semicircular recess 10 b of the first case member 10. A band insertion hole 18a is formed in the band holding portion 18, and a band 85 (FIG. 2) is inserted into the band insertion hole 18a. By hanging the band 85 on the band holding unit 18 and the power line 80, the split case 2 can be held at a desired position with respect to the power line 80.

  As shown in FIG. 2, the signal extraction line 90 includes a winding portion 91 and a connection terminal 92. The winding portion 91 is wound so as to be wound around the partition wall 14 and the first core member 50 (in the vicinity of the contact surface 51A). Therefore, a part of the winding part 91 is accommodated in the signal extraction line accommodating part 17, and the other part is accommodated in a space 3S to be described later in the through hole 3a. Both ends of the winding portion 91 are bundled together in the vicinity of the signal extraction line hole 2 c and extend toward the connection terminal 92. The connection terminal 92 is a terminal for connecting to a communication device such as a modem. As described above, the signal lead-out line holding part 17 is provided with the signal lead-out line holding member 13, so that the winding part 91 is difficult to come off from the signal lead-out line accommodating part 17. Therefore, it is possible to hold the winding part 91 at a predetermined position in the signal extraction line accommodating part 17.

  Next, the positional relationship between the through-hole 3a of the split core 3 and the pair of power line holes 2a and 2b will be described. 4, 5, and 7, the center line passing through the center of the through hole 3a of the split core 3 is defined as a center line L1. A center line passing through the centers of the pair of power line holes 2a and 2b is defined as a center line L2. That is, the center line L2 is the center line of the power line 80. As shown in FIGS. 4, 5, and 7, the center line L <b> 1 is shifted in a direction approaching the signal lead-out line accommodating portion 17 with respect to the center line L <b> 2. That is, the center of the through-hole 3a of the split core 3 is the direction from the core housing portions 16 and 26 toward the signal lead-out wire housing portion 17 with respect to the center of the pair of power line holes 2a and 2b (center of the power line 80). Is eccentric. Therefore, in a state where the power line 80 is inserted into the through hole 3a, a space 3S (FIG. 2) is secured on the side close to the signal extraction line accommodating portion 17 inside the through hole 3a. And the winding part 91 of the signal extraction line 90 is wound using space 3S. According to such a configuration, since the winding portion 91 of the signal extraction line 90 and the power line 80 can be separated from each other, disconnection or short-circuit due to contact can be prevented.

  According to the power line carrier signal input / output device 1 according to the first embodiment described above, the power line carrier signal input / output device can be provided with a simple configuration by using the split case 2.
