  One embodiment is described based on an accompanying drawing.

  The antenna-equipped cage 22 includes, as basic components, a cabinet 1 for flowing rainwater and an antenna plate 5 that overlaps the outer surface of the cabinet 1.

  In the embodiment of the attached drawings, the antenna-equipped cage 22 has a double cylinder structure by further including an outer cylinder portion 23 that covers the tubular casing 1, and at the end in the longitudinal direction, A connecting body 24 that is connected in communication with the housing 1 is provided.

  The antenna plate 5 is formed by providing the antenna portion 2 on the metal plate 3.

  The antenna unit 2 is constituted by a slot antenna in which a slot 28 formed long in the axial direction of the housing 1 is provided on a thin metal plate 3 (including metal foil) having a vertically long rectangular shape.

  In the embodiment of FIG. 7, a plurality of slots 28 are arranged in the vertical direction in the antenna portion 2 formed on the metal plate 3, and adjacent slots 28 are connected by a narrow groove 25. Each slot 28 is formed in a bow tie shape in which the vertices of a triangle are abutted with each other.

  The antenna unit 2 includes a first receiving unit 29 that receives radio waves in a first frequency band (for example, 473 to 600 MHz) and a second receiving unit that receives radio waves in a second frequency band (for example, 600 to 720 MHz). 30.

  The first receiving unit 29 includes a slot 28 and a peripheral portion of the slot 28. The second receiving unit 30 is configured by a steel plate portion adjacent to the slot 28 in the vertical direction.

  The length of the slot 28 constituting the first receiving unit 29 in the vertical direction is the same as the length of the electrical half wavelength of the radio wave in the first frequency band. The circumferential length of the second receiving unit 30 is the same as the electrical half-wavelength of the radio wave in the second frequency band.

  That is, the center frequency in the first frequency band is 536.5 MHz, and the electrical half wavelength λ / 2 of the radio wave in the first frequency band is about 28 cm. The length is about 28cm. Further, since the center frequency of the second frequency band is 660 MHz and the electric half wavelength λ / 2 of the radio wave in the second frequency band is about 23 cm, the circumferential direction of the second receiving unit 30 is The length is about 23 cm.

  In the embodiment shown in the accompanying drawings, the apex portions of the triangles on both sides of the slot 28 of the metal plate 3 are the power feeding portions 9.

  As shown in FIG. 2, a pair of insertion holes is formed in each of the power feeding portions 9.

  A power supply cable 11 is connected to the power supply unit 9.

  The power supply cable 11 connected to the power supply unit 9 is constituted by a coaxial cable, and as shown in FIG. 2, the outer side of the inner core wire 32 is covered with a core wire outer skin portion 33, and the outer periphery of the core wire outer skin portion 33 is formed of a knitted wire. The outer conductive wire 34 is covered with the outer skin portion 35 and covered with the wire 34.

  The end portion of the power supply cable 11 is formed as a conductive portion 7 where the outer sheath portion 35 is removed and the end portion of the outer conductive wire 34 is exposed, and further protrudes from the end portion of the outer conductive wire 34 to protrude from the end portion of the outer conductive wire 34. A portion where 33 is exposed is formed, and a portion where the core wire 32 protrudes from an end portion of the core wire skin portion 33 is formed as another conductive portion 7.

  The core wire 32 and the outer conductive wire 34 of the power feeding cable 11 are connected to the pair of power feeding portions 9 by the fasteners 8 respectively.

  The stopper 8 is formed of a metal material such as a brass plate or a stainless steel plate having elasticity, and as shown in FIGS. 2, 10 (c) and 10 (d), from both ends of the center piece 14 to the center piece 14. The side piece 15 protrudes and is formed in a substantially U shape or a substantially C shape.

  In FIG. 10, the distance between the protruding bases of the both side pieces 15 of the stopper 8 is A, the distance between the protruding tips of the two side pieces 15 is B, the distance between the substantially central parts in the protruding direction of the both side pieces 15 is C, Assuming that the width of 8 is E, the distance between the pair of insertion holes is F, and the length of the insertion hole is G, A≈B≈F, G> E, and C> F.

  There are two types of fasteners 8, a core wire fastener 13 and an outer conductor fastener 12. Each dimensional relationship of the pair of insertion holes into which the core wire fastener 13 and the core wire fastener 13 are inserted, the outer conductor fastener 12 and the outside Each dimensional relationship of the insertion hole into which the conducting wire stopper 12 is inserted is the above dimensional relationship.

  In order to connect the outer conductive wire 34 of the power supply cable 11 to the one power supply portion 9 with the outer conductive wire stopper 12, the connection is performed as follows.

  That is, the both side pieces 15 of the outer conductive wire stopper 12 are inserted into a pair of insertion holes provided in one power supply portion 9. In this case, the both side pieces 15 are inserted while being elastically deformed, and since C> F in the inserted state, the outer conductive wire stoppers 12 are held so as not to be carelessly removed from the insertion holes.

  Next, as shown in FIG. 11, the outer conductive wire 34 is fitted between the both side pieces 15. Next, as shown in FIG. 12 (a), the central piece 14 is set to be positioned in the positioning portion 18 provided on the caulking die 17 of the caulking device 16, and the caulking device 16 is caulked as shown in FIG. 12 (b). The punch 19 is lowered and the both side pieces 15 are bent and adhered along the outer periphery of the outer conductive wire 34 which is the conductive portion 7. As a result, the outer conductive wire 34 is held by the both side pieces 15, the outer conductive wire 34 is brought into contact with the metal plate 3, and the central piece 14 of the outer conductive wire stopper 12 is brought into contact with the metal plate 3, which is electrically and mechanically Connected to.

  The electrical connection with the metal plate 3 is not limited to the one in which the outer conductive wire 34 and the central piece 14 are in electrical contact with the metal plate 3 as in the above example. Only the outer conductive wire 34 may be brought into electrical contact, or only the central piece 14 may be brought into electrical contact with the metal plate.

  The dimension J in FIG. 13B is an extremely short dimension with J = 2D + H + K, where D is the thickness of the stopper 8, H is the thickness of the metal plate 3, and K is the outer diameter of the outer conductive wire 34. Thus, the outer diameter of the outer skin portion 35 is substantially equal.

  The connection of the core wire 32 of the power supply cable 11 to the other power supply portion 9 by the core wire clamp 13 is performed in the same manner as the connection of the outer conductive wire 34 described above, and is electrically and mechanically connected as shown in FIG. The

  The dimension M in FIG. 14 is shorter than the dimension J in FIG. 13B because the diameter of the core wire 32 is shorter than that of the outer conductive wire 34.

  Thus, by connecting, it is not necessary to tighten the screw in connection, and productivity can be improved. In addition, screws and nuts for screw tightening are unnecessary, and cost reduction can be measured. Furthermore, by fixing by caulking instead of screw tightening, there is no looseness of the screw due to vibration or the like, connection failure can be suppressed, and reliability can be improved.

  Further, the dimension of the connecting portion (dimension J in FIG. 13B, dimension M in FIG. 14) can be shortened. In particular, the dimension J can be made substantially equal to the outer diameter of the outer skin portion 35.

  As described above, the antenna plate 5 in a state where the feeding cable 11 is connected is a cylindrical or rectangular tube-shaped casing 1 that is uniformly curved in the vertical direction so as to have a horizontal cross-section C shape or a polygonal shape. They are wound around the outer peripheral surface, stacked, and attached using an adhesive or attachment member 31.

  The embodiment shown in the accompanying drawings shows an example in which the attachment member 31 as shown in FIG. 8 is used as shown in FIGS.

  As described above, the power supply cable 11 mechanically and electrically connected to the power supply unit 9 is disposed along the axial direction of the housing 1 on the outer surface of the antenna plate 5 wound around the outer surface of the housing 1.

  In arranging along the axial direction, the slots 28 are avoided.

  The attachment member 31 for attaching the antenna plate 5 to the outer peripheral surface of the housing 1 is formed of a nonconductive material such as a nonconductive synthetic resin. Further, as shown in FIG. 8, the attachment member 31 is configured by rotatably connecting one end portions of a pair of half bodies 38 with a bearing portion 39, and a locking portion at the other end portion of the pair of half bodies 38. 40 and the locked portion 41 are freely lockable.

  The attachment member 31 includes a cable holding portion 42 that holds the position of the power feeding cable 11 with respect to the antenna plate 5, and the power feeding cable 11 is held by the cable holding portion 42.

The attachment member 31 of the present embodiment has a total of four protruding portions including a bearing portion 39, a locking portion 40 and a locked portion 41, and a cable holding portion 42. The protruding portions are arranged at equal intervals in the circumferential direction, that is, protrude in the radially outward direction every 90 °.

  A casing 22 with an antenna having a double cylinder structure is formed by covering the casing 1 with the antenna plate 5 wound around the outer periphery thereof with the outer cylinder portion 23.

  When the casing 1 having the antenna plate 5 wound around the outer periphery is covered with the outer cylinder portion 23, the mounting member 31 has a protruding portion, so that the casing 1 and the casing 1 are provided substantially at the center of the outer cylinder portion 23. In addition, the center of the antenna plate 5 is disposed, and comes into contact with or in close proximity to the inner peripheral surface of the outer cylinder portion 23.

  A connecting portion between the conductive portion 7 and the power feeding portion 9 of the power feeding cable 11 is covered with an outer cylinder portion 23, and the power feeding cable 11 is connected to the outer surface of the antenna plate 5 wound around the outer periphery of the housing 1 and the outer cylinder portion 23. It is arranged between.

  Here, since the dimension J of FIG. 13B is short (substantially equal to the outer diameter of the outer skin portion 35), the gap between the outer surface of the antenna plate 5 and the outer cylinder portion 23 is arranged as the power supply cable 11. If the dimensions necessary for this are secured, the connecting portion between the conductive portion 7 and the power feeding portion 9 can be sufficiently accommodated in the gap.

  Thereby, the diameter of the outer cylinder part 23 can be made small, cost can be reduced, and the external appearance of the collar 22 with an antenna of a double cylinder structure becomes good.

  Since the core wire 32 of the power supply cable 11 has a smaller diameter than the outer conductive wire 34, the core wire 32 is connected by a screw type using screws and nuts without using the core wire stopper 13. Is also possible. In this case, the thickness dimension of the connecting portion of the core wire 32 can be shortened.

  Moreover, the connection part of the electroconductive part 7 and the electric power feeding part 9 is covered with the outer cylinder part 23, and a connection part can be protected, and an object and a person are not caught on a connection part, and outside air, sunlight, It becomes possible to protect the connection portion from rainwater, and the reliability is improved.

  The double cylinder-structured flange 22 with an antenna is provided with a connection body 24 at an end in the longitudinal direction, and the vertical connection body 24 and the vertical ends of the outer cylinder 23 are connected to the upper and lower connection bodies 24. The upper and lower connecting bodies 24 communicate with the housing 1.

  The power feeding cable 11 along the axial direction of the housing 1 reaches the lead-out portion 43 provided in the connection body 24, and the connection tool 44 provided at the end of the power-feeding cable 11 is fitted in the hole constituting the lead-out portion 43. Mounted.

  A connection tool provided at an end of the television cable 45 is electrically connected to the connection tool 44. The television cable 45 is introduced into the building from the outer wall 47 and the eaves ceiling 48 of the building 46 and connected to the television side in the existing building 46.

  FIG. 9 shows an example in which the ridge 22 with an antenna is used as a part of the ridge. In FIG. 9, reference numeral 49 is an eaves bowl, 50 is a water collector, 51 is an elbow, 52 is a call bowl, and 53 is a general bowl.

  When the antenna-equipped cage 22 is used as a part of the cage, the connecting body 24 of the antenna-attached cage 22 is connected to a general cage 53 or an elbow 51, and rainwater is allowed to flow through the cylindrical enclosure 1.

  At the time of connection, the antenna-equipped cage 22 is rotated around the axis to direct the antenna unit 2 in the strongest receiving direction.

  The antenna plate 5 may be formed by laminating a coating film 4 having electrical insulation on both the front and back surfaces or the surface of the metal plate 3 having the antenna portion 2.

  In the case of the antenna plate 5 in which the covering film 4 is laminated on both the front and back surfaces of the metal plate 3, the portion corresponding to the power feeding portion of the front and back both surfaces or the covering film 4 on one side is removed as shown in FIG. Then, the conductive portion 7 or the central piece 14 of the fastener 8 is brought into electrical contact with the exposed surface 20.

  In the case of the antenna plate 5 in which the coating film 4 is laminated on the surface of the metal plate 3, since the back surface of the power feeding unit 9 is exposed, the central piece 14 of the fastener 8 is brought into electrical contact with the exposed surface 20.

  Thus, by laminating the covering film 4 on both the front and back surfaces of the metal plate 3, the metal plate 3 can be protected, the occurrence of rust on the metal plate 3 can be suppressed, and the antenna performance can be prevented from deteriorating.

  In the above-described embodiment, the example in which the outer cylinder portion 23 is provided has been described. However, the outer cylinder portion 23 may not be provided.

  When the outer cylinder portion 23 is not provided, in the antenna plate 5 in which the metal plate 3 is covered with the covering film 4 as described above, the metal plate 3 is not exposed to rainwater, outside air, or sunlight, and the deterioration of the antenna portion 2 is suppressed. it can.

  Also in this case, the dimension in the thickness direction of the connecting portion between the conductive portion 7 and the power feeding portion 9 can be shortened, the protruding length from the outer surface of the housing 1 can be shortened, and people and objects are caught on the connecting portion. Is suppressed.
