  FIG. 1 is a perspective view showing a cable connector according to an embodiment. FIG. 2 is a perspective view showing a state where the case is opened in the cable connector shown in FIG. 1. FIG. 3 is a diagram illustrating a cable connection structure of the cable connector.

  A cable connector 1 shown in FIGS. 1 and 2 is for connecting a cable body M formed by coating an optical fiber F and a tension member (steel wire) T, and an optical drop cable A including a support wire S to each other. belongs to. The cable connector 1 includes a cable connection structure 3, a case (accommodation box) 7 that accommodates the cable connection structure 3, and cable holding portions 9a and 9b. The case 7 is made of a material such as polypropylene (PP), for example, and is provided so as to be freely opened and closed.

  The cable connection structure 3 connects the support wire coupler 10 for connecting the support wires S of the optical drop cable A to each other, the optical fibers F of the cable body M of the optical drop cable A, and the tension members T to each other. And a base member (fixing member) 16 that integrally fixes the support wire coupler 10 and the fiber connectors 12 and 14 together.

  First, the support wire coupler 10 will be described with reference to FIGS. FIG. 4 is a perspective view showing the support wire coupler. FIG. 5 is a plan view showing the support wire coupler. 6 is a cross-sectional view taken along line VI-VI in FIG.

  The support line connector 10 includes a pair of support line fixing parts (a support line fixing part 20 and a support line fixing part 22), and a connection part 24 that connects the support line fixing part 20 and the support line fixing part 22 to each other. ing. The support line fixing component 20 and the support line fixing component 22 are disposed to face each other (and in opposite directions) along a direction (predetermined direction) along the reference line BL. The support line fixing parts 20 and 22 fix the support lines S inserted from the one end portions 20a and 22a in the direction along the reference line BL, respectively.

  As the support wire fixing parts 20 and 22, for example, a C-type plug-type retainer for securing a support wire of a predetermined cable to a retaining column or the like can be used. Here, since the support wire fixing component 20 and the support wire fixing component 22 have the same configuration, the support wire fixing component 20 will be mainly described below.

  As shown in FIG. 6, the support line fixing component 20 (support line fixing component 22) includes a main body member 25, a pair of clamping members 26 and 27, and an elastic member 28. The outer shape of the main body member 25 has a substantially frustoconical shape that increases in diameter from one end portion 20a of the support wire fixing component 20 toward the other end portion 20b.

  Further, the main body member 25 has a substantially frustoconical (tapered) through-hole 25h whose diameter increases (expands) from the one end 20a to the other end 20b of the support wire fixing component 20, similarly to its outer shape. doing. The main body member 25 is made of, for example, a conductive metal such as aluminum or zinc.

  An introduction pipe 29 is attached to one end portion 25a of the main body member 25 (the end portion on the one end portion 20a side of the support wire fixing component 20). The introduction pipe 29 forms an introduction port when the support line S is inserted into the through hole 25 h of the main body member 25 and receives the jacket SC of the support line S. On the other hand, the cap 30 is attached to the other end 25b of the main body member 25 (the end on the other end 20b side of the support wire fixing component 20) so as to close the through hole 25h. A hole 30 h is provided in the center of the cap 30. The support line S inserted into the through hole 25h of the main body member 25 is led out from the hole 30h.

  A flange 31 projects from the outer peripheral portion of the main body member 25. The flange 31 has a pair of notches 31a (see FIGS. 4 and 5). The notches 31a are formed at positions facing each other. The connecting component 24 is inserted into each of the notches 31a.

  The holding members 26 and 27 are accommodated in the through holes 25 h of the main body member 25. The sandwiching member 26 and the sandwiching member 27 are disposed to face each other along a direction orthogonal to the reference line BL so as to sandwich the support line S inserted into the through hole 25h. The clamping members 26 and 27 have, for example, a shape that is formed by dividing a substantially truncated cone-shaped member into two on the central axis.

  Therefore, the clamping members 26 and 27 are slidable on the inner surface of the through-hole 25 h of the main body member 25 in a state where they are overlapped (opposed). Engaging teeth 26t and 27t are formed on surfaces 26s and 27s facing each other in the clamping member 26 and the clamping member 27, respectively. The clamping members 26 and 27 are made of, for example, conductive metal.

  The elastic member 28 is accommodated in the through hole 25 h of the main body member 25, and is disposed between the cap 30 and the clamping members 26 and 27. The elastic member 28 has the holding members 26 and 27 facing each other in the through hole 25h of the main body member 25 on the one end portion 20a side of the support wire fixing component 20 (that is, on the one end portion 25a side of the main body member 25). Energize.

  Therefore, the clamping members 26 and 27 are pressed in the direction in which the through hole 25h narrows while sliding on the inner surface of the through hole 25h by the biasing force of the elastic member 28. For this reason, the clamping member 26 and the clamping member 27 have such a force that they are in close contact with each other. Here, the elastic member 28 is a coil spring.

  In the support wire fixing component 20 configured as described above, the support wire S is inserted from the introduction pipe 29 into the through hole 25h of the main body member 25, and the clamping members 26 and 27 are moved against the urging force of the elastic member 28. When pushed into the end portion 25b, the holding members 26 and 27 are pushed toward the other end portion 25b while sliding on the inner surface of the through hole 25h, and between the surface 26s of the holding member 26 and the surface 27s of the holding member 27. A gap is created. The support line S is led out from the hole 30h of the cap 30 through the gap between the surface 26s and the surface 27s.

  In this state, when the pressing of the support line S is stopped, the holding members 26 and 27 are urged by the elastic member 28, and the support line S is held and fixed by the holding member 26 and the holding member 27. At this time, the support line S is securely fixed by the meshing teeth 26t and 27t formed on the surfaces 26s and 27s of the clamping members 26 and 27, respectively. Thus, according to the support wire fixing component 20, the support wire S can be easily fixed only by inserting the support wire S from the one end 20a.

  The support line fixing component 20 and the support line fixing component 22 configured as described above are arranged to face each other while the insertion direction of the support line S is opposite to each other, and are connected to each other by the connection component 24. The connecting part 24 has a rod shape and extends from the support line fixing part 20 to the support line fixing part 22. The connecting component 24 is made of, for example, a conductive metal such as SUS. Due to the connecting part 24, the supporting line connecting part 10 is electrically connected to the supporting line fixing parts 20 and 22.

  As shown in FIGS. 4 and 5, the connecting component 24 includes a pair of straight portions 32 and a curved portion 33. The straight line portions 32 extend in parallel with each other in a straight line from the support line fixing component 20 to the support line fixing component 22 in a direction along the reference line BL. The bending portion 33 extends in a substantially U shape in a direction intersecting the extending direction of the linear portions 32 (in a direction intersecting the reference line BL) so as to connect the one end portions 32a of the pair of linear portions 32. doing.

  The other end portion 32 b of the linear portion 32 is inserted into a notch 31 a formed in the flange 31 of the main body member 25 in the support line fixing component 20. The other end portion 32b of the linear portion 32 is formed with a locking portion 32d having a size larger than the size of the notch 31a. For this reason, the connection component 24 inserted through the notch 31a of the support line fixing component 20 is locked to the support line fixing component 20 without coming out of the support line fixing component 20 in the insertion direction of the support line S. That is, the support wire fixing component 20 is locked to the connecting component 24 at the other end portion 32 b of the linear portion 32.

  On the other hand, one end portion 32 a of the linear portion 32 is inserted into a notch 31 a formed in the flange 31 of the main body member 25 in the support wire fixing component 22. In this state, the bending portion 33 extends along the direction intersecting the reference line BL so as to follow the outer shape of the main body member 25 of the support line fixing component 22. For this reason, the connecting part 24 inserted through the notch 31a of the support line fixing part 22 is locked to the support line fixing part 22 at the curved portion 33 without coming out of the support line fixing part 22 in the insertion direction of the support line S. Is done. That is, the support wire fixing component 22 is locked to the connecting component 24 at the bending portion 33.

A connection member 36 that accommodates a conducting member 34 that is electrically connected to the tension member T of the cable body M of the drop cable A is provided.

  The connection member 36 includes an accommodation part (first accommodation part) 37 and an accommodation part (second accommodation part) 38. The connecting member 36 is made of, for example, a material such as polyacetal (PA), polyoxymethylene (POM), or polycarbonate (PC). The accommodating part 37 accommodates the terminal part of the tension member T and the conducting member 34, and the accommodating part 38 accommodates the terminal part of the optical fiber F and the optical connector C.

  The accommodating portion 37 has a long bottom wall (side wall) 40 and a pair of long side walls 41 and 42 erected from the bottom wall 40. The accommodating portion 37 is formed in a long shape by the bottom wall 40 and the side walls 41 and 42 so that the cross-sectional shape thereof is substantially U-shaped. The accommodating portion 37 accommodates the terminal portion of the tension member T and the conducting member 34 in the accommodating region AR1 defined by the bottom wall 40 and the side walls 41 and 42. An opening 43 and an opening 44 are formed in one end 37a and the other end 37b in the longitudinal direction of the accommodating portion 37, respectively. An opening 45 is formed in the side wall 41 of the housing portion 37.

  A cylindrical engagement portion (opening) 46 that communicates with the opening 43 is provided at one end 37 a of the housing portion 37. The engaging part 46 is engaged with one end part 37 a of the accommodating part 37 in the fiber connector 12, where one end part 57 a of an extending part 57 of the conducting member 34 described later is located. On the other hand, a cable fixing portion 47 is provided at the other end portion 37 b of the housing portion 37. The cable main body M led out from the other end portion 37b of the housing portion 37 is inserted into the cable fixing portion 47 when the terminal portion of the tension member T is housed in the housing area AR1 of the housing portion 37.

  A substantially rectangular parallelepiped space SP is formed inside the cable fixing portion 47, and the cable body M is inserted into the space SP. In a state where the cable main body M is inserted into the space SP of the cable fixing portion 47, the cable main body M can be fixed to the fiber connector 12 by inserting the fixing member 48 into the space SP.

  The accommodating portion 38 is formed integrally with the accommodating portion 37. More specifically, the housing portion 38 includes a bottom wall 50 formed continuously from the bottom wall 40 of the housing portion 37 and a side wall erected from the bottom wall 50 so as to face the side wall 42 of the housing portion 37. 51, a side wall portion 52 erected from the bottom wall 50 so as to connect the side wall 42 and the side wall 51, and a bottom wall 50 extending from the side wall 51 toward the other end portion 37 b of the accommodating portion 37. And a side wall portion 53 erected. The accommodating portion 38 accommodates the terminal portion of the optical fiber F in the accommodating region AR2 defined by the side wall 42, the bottom wall 50, the side wall 51, and the side wall portions 52 and 53 of the accommodating portion 37.

  That is, the accommodation area AR1 of the accommodation portion 37 that accommodates the terminal portion of the tension member T and the conducting member 34 and the accommodation area AR2 of the accommodation portion 38 that accommodates the terminal portion of the optical fiber F are separated from each other by the side wall 42. ing. However, the side wall 42 does not reach the other end portion 37 b of the accommodating portion 37 and is not connected to the side wall portion 53. For this reason, a communication port 54 is formed between the side wall 42 and the side wall portion 53 so as to communicate the accommodation area AR1 and the accommodation area AR2.

  Therefore, the terminal portion of the optical fiber F branched from the tension member T can be introduced and accommodated in the accommodating area AR2 via the communication port 54 while accommodating the terminal portion of the tension member T in the accommodating area AR1. On the side wall 51 of the accommodating portion 38, a protrusion 51a is formed for suppressing the lifting of the end portion of the optical fiber F accommodated in the accommodating area AR2. The side wall 51 is formed with slits 51s. The side wall portion 53 is curved so that a space for handling the extra length of the optical fiber F can be sufficiently secured in the accommodation area AR2. The outer portion of the side wall 53 is rounded and chamfered in a substantially spherical shape.

  Here, in the accommodating portion 38, the side wall portion 52 is located on the one end portion 37 a side of the accommodating portion 37, and the side wall portion 53 is located on the other end portion 37 b side of the accommodating portion 37.
