Embodiment 1
Embodiment 1 of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view showing an example of a first device and a second device in the first embodiment. The first device 10 is attached to the second device 11 when used. For example, the first device 10 is one of a wireless device or an antenna device that performs transmission or reception (or transmission and reception) of a wireless signal with the wireless device, and the second device 11 is the wireless device. It is the other device of the device and the antenna device.

The first device 10 includes a convex portion 12, a support member 13, and an urging member 14. That is, the convex portion 12, the support member 13, and the biasing member 14 are provided in the first device 10. The convex portion 12 is a member that protrudes from one surface of the first device 10 and is inserted into a hole of the second device 11 described later. The support member 13 is a member that supports the convex portion 12 that protrudes from one surface of the first device 10.

Note that the xyz coordinates in FIG. 1 are defined as follows. In FIG. 1, the x direction is a direction in which the convex portion 12 is slid (left direction on the paper surface), the y direction is the hole width direction (front direction on the paper surface) of the second device 11, and the z direction is the second device 11. In the height direction (upward direction on the paper surface). The x direction, the y direction, and the z direction are directions orthogonal to each other.

In FIG. 1, the convex portion 12 and the support member 13 have a rectangular parallelepiped shape. A convex portion 12 is provided at the tip of the support member 13 of the first device 10. Here, the support member 13 is formed to be narrower than the convex portion 12.

The biasing member 14 is a member that is provided in the first device 10 and applies a biasing force that biases the convex portion 12 in the direction from the first device 10 to the second device 11. The urging member 14 is configured using an elastic body such as a spring or rubber, for example. The urging member 14 is an elastic body provided on the side surface of the support member 13 in FIG. 1, but may be provided at another location. The biasing member 14 has a larger width in the x direction and the y direction (longitudinal and lateral directions) than the support member 13.

The second device 11 includes a recess 15. That is, the recess 15 is provided in the second device 11. The concave portion 15 is a hole into which the convex portion 12 of the first device 10 is inserted.

The recess 15 has an insertion hole 16 and a slide hole 17. The insertion hole 16 is a hole into which the convex portion 12 can be inserted, and the convex portion 12 is inserted when the first device 10 and the second device 11 are attached. Here, the insertion hole 16 is larger than the protrusion 12 so that the protrusion 12 can be inserted into the insertion hole 16. In other words, the lengths of the insertion holes 16 in the x direction and the y direction are larger than the lengths of the convex portions 12 in the x direction and the y direction.

The slide hole 17 is a hole provided in the x direction continuously to the insertion hole 16 and holds the convex portion 12 inserted from the insertion hole 16 so as to be slidable inside. Here, “holding” the convex portion 12 is an attempt to pull out the convex portion 12 in a direction in which the first device 10 and the second device 11 are separated in a state where the convex portion 12 is inserted into the slide hole 17. Sometimes it is in a state where it cannot be pulled out easily.

Therefore, the slide hole 17 is smaller than the convex portion 12 and larger than the support member 13. In other words, the width in the y direction at the opening of the slide hole 17 is smaller than the length in the y direction of the convex portion 12 and larger than the length in the y direction of the support member 13. Further, the length of the slide hole 17 in the x direction is larger than the length of the convex portion 12 in the x direction. Since the convex part 12 is latched by the edge part of the slide hole 17, and the slide hole 17 hold | maintains the convex part 12 so that sliding is possible, the drop-off | omission from the slide hole 17 of the convex part 12 is prevented.

FIG. 2A is a cross-sectional view showing an example of the second device 11 when viewed from the side (left side in FIG. 1) where the slide hole 17 is provided in the x direction. The slide hole 17 has a constricted portion 17a and a holding portion 17b. The constricted portion 17a is formed narrower in the y direction than the holding portion 17b so that the slide hole 17 engages the convex portion 12. The support member 13 is locked at the connecting portion (edge portion) between the constricted portion 17a and the holding portion 17b.

The constricted portion 17 a is larger than the support member 13 and opens smaller than the convex portion 12 and the biasing member 14. Further, the holding portion 17 b is opened larger than the convex portion 12. That is, the width of the constricted portion 17a in the y direction is smaller than the length of the convex portion 12 and the biasing member 14 in the y direction and larger than the length of the support member 13 in the y direction. The width of the holding portion 17b in the y direction is larger than the width of the convex portion 12 in the y direction, and the depth of the holding portion 17b in the z direction is larger than the height of the convex portion 12 in the z direction. Therefore, the convex part 12 can be hold | maintained at the holding | maintenance part 17b. In this way, the slide hole 17 holds the convex portion 12 so as to be slidable inside.

When the support member 13 has another shape, the length required for the slide hole 17 is different from that described above. For example, when the support member 13 has a cylindrical shape, the width in the y direction of the constricted portion 17 a is longer than the diameter of the support member 13. Thus, the constricted portion 17a has a width that allows the support member 13 to slide.

FIG. 2B is a cross-sectional view showing an example when the second device 11 is viewed from the y direction (front side of the paper). In FIG. 2B, cross sections of the insertion hole 16 and the slide hole 17 are shown. Here, in the holding portion 17b (slide hole 17), the convex portion 12 moves from the first device 10 side to the second device 11 side from the insertion hole 16 side to the side opposite to the insertion hole 16 (z direction). An inclination (taper) is provided.

Here, the support member 13 is inserted deeper into the second device 11 side as the convex portion 12 moves in the x direction. In other words, the support member 13 moves more in the −z direction as the convex portion 12 is slid in the opposite direction from the insertion hole 16 side. For this reason, the surface of the first device 10 and the surface of the second device 11 are closer to each other, and the biasing member 14 provided on the support member 13 receives pressure from the surface of the second device 11 and compresses more. (The height becomes shorter), the urging force increases. Thus, the holding portion 17b (slide hole 17) is inclined so that the urging force of the urging member 14 increases as the convex portion 12 is slid from the insertion hole 16. Therefore, the first device 10 and the second device 11 are fixed.

As described above, the convex portion 12, the biasing member 14, and the concave portion 15 constitute an attachment structure (attachment unit) for attaching the first device 10 and the second device 11. Due to this attachment structure, the operator can perform the following operations to attach the first device 10 and the second device 11.
(A) inserting the convex portion 12 into the insertion hole 16, and (b) sliding the convex portion 12 inserted into the insertion hole 16 into the slide hole 17.

As described above, the attachment structure shown in the first embodiment can easily attach the first device 10 and the second device 11. In particular, when the first device 10 is one of a wireless device and an antenna device and the second device 11 is the other device, the mounting structure allows the wireless device to be easily attached. To do. For this reason, there is an advantage that the work of the wireless device becomes easy for the worker.

In the case where the first device 10 is one of the wireless device or the antenna device and the second device 11 is the other device, in a state where the convex portion 12 is inserted into the slide hole 17, The end face of the waveguide of the first device 10 and the waveguide of the second device 11 may be opposed to each other. With this configuration, the wireless device and the antenna device can be easily attached, and a wireless device including the wireless device and the antenna device can execute transmission / reception of a wireless signal.

In Embodiment 1, for example, a plate-like member may be provided between the convex portion 12 and the biasing member 14. In this case, the urging member 14 receives a stronger pressure from the member as the convex portion 12 slides from the insertion hole 16 in the slide hole 17. Even in such a configuration, the biasing member 14 can apply a biasing force that biases the convex portion 12 in the direction of the second device 11.

Embodiment 2
The second embodiment of the present invention will be described below with reference to the drawings. In the second embodiment, a specific example of the device and the mounting structure shown in the first embodiment will be described.

FIG. 3 is an external view showing an example of a wireless device according to the second embodiment. The wireless device 20 according to FIG. 3 includes an ODU 21, an ANT 22, a conversion plate 23, and a connection unit 24. In FIG. 3, the wireless device 20 in a state where the ODU 21 and the ANT 22 are mounted is shown in a perspective view. The wireless device 20 is attached to the pillar 91 by an attachment device 90. Hereinafter, each unit of the wireless device 20 will be described.

The ODU 21 (first device) is an outdoor wireless device, and executes at least one of signal processing for a transmission signal transmitted from the ANT 22 and signal processing for a reception signal received from the ANT 22. The ODU 21 is housed in a box-shaped housing in the second embodiment, but the housing may have other shapes. The ODU 21 includes a waveguide that performs at least one of transmission and reception of a radio signal with the ANT 22.

The ANT 22 (second device) is connected to the ODU 21 via the conversion plate 23, and executes at least one of receiving a radio signal or transmitting a transmission signal output from the ODU 21 by radio. For example, when the ANT 22 receives a radio signal, the received radio signal is output to the ODU 21. The ANT 22 has a waveguide that performs at least one of transmission and reception of a radio signal with the ODU 21.

The conversion plate 23 is a plate that connects the ODU 21 and the ANT 22. By changing the angle at which the ODU 21 is attached to the conversion plate 23, the polarization of the wireless communication in the wireless device 20 can be changed. Details of this will be described later.

The connection unit 24 is a member that is provided in advance in the ANT 22 and connects the conversion plate 23 and the attachment device 90 to the ANT 22.

In Embodiment 2, the conversion plate 23 is attached to the ANT 22 in advance, and the operator attaches the ODU 21 to the ANT 22 by attaching the ODU 21 to the conversion plate 23.

FIG. 4 is a perspective view showing an example of the structure of the mounting surface of the ODU 21 and the conversion plate 23. FIG. 4 shows a state where the ANT 22 and the ODU 21 are separated (a state where the ODU 21 is not attached to the ANT 22). Hereinafter, detailed configurations of the ODU 21 and the conversion plate 23 will be described.

FIG. 5 is a perspective view showing an example of the state of the ODU 21 when the ball plunger 28 is mounted on the ODU 21. The ODU 21 has a waveguide hole 26 at the center thereof, and the waveguide of the ODU 21 is disposed inside the waveguide hole 26. The waveguide hole 26 is provided so that the waveguide of the ODU 21 can be seen when the ODU 21 is viewed from the attachment surface 25 side. The waveguide hole 26 is also provided so as to face the waveguide hole 30 when the ODU 21 is mounted on the ANT 22.

Furthermore, in the ODU 21, tap portions 27 are provided at the four corners of the square mounting surface 25. In a plan view including the attachment surface 25 (a plan view perpendicular to the attachment direction (projection direction of a ball plunger 28 described later)), the four tap portions 27 are arranged radially symmetrically about the waveguide hole 26. Yes. That is, the four tap portions 27 are disposed on diagonal lines that pass through the center of the mounting surface 25. The tap portion 27 is a female screw provided with a screw hole for attaching the ball plunger 28.

The ball plunger 28 corresponding to the male function of the clamp is screwed and attached to the two tap portions 27a on the diagonal line among the four tap portions 27. In other words, the two ball plungers 28 are mounted on one diagonal passing through the center of the mounting surface 25. Since the two ball plungers 28 are inserted into a pin insertion hole 35 described later, the ODU 21 is attached to the ANT 22.

The ball plunger 28 protrudes in the vertical direction (z direction) from the mounting surface 25 of the ODU 21, and the ODU 21 and the conversion plate 23 are attached by joining the protruding portion to the conversion plate 23. That is, the tap portion 27 can attach the ODU 21 to the conversion plate 23 by mounting the ball plunger 28.

6A to 6D are diagrams showing an example of the configuration of the ball plunger 28. FIG. Hereinafter, the configuration of the ball plunger 28 will be described.

FIG. 6A is a diagram showing an example of an appearance of the ball plunger 28 as viewed from the side where the ball shaft pin 28a is provided (the upper surface side of the ball plunger 28). The ball plunger 28 includes a ball shaft pin 28a and a ball plunger shell 28b.

The ball plunger shell 28b is a male screw having an upper surface 28d (head) and a spiral portion 28e. Here, the ball plunger shell 28 b fixes the ball shaft pin 28 a to the ODU 21. A part of the ball shaft pin 28a is accommodated in the spiral portion 28e, and a spherical tip portion 28c (convex portion) protrudes from the upper surface 28d.

FIG. 6B is an external view showing an example of the ball shaft pin 28a. The ball shaft pin 28a includes a tip portion 28c, a pin connection portion 28f, an intermediate portion 28g, and a bottom surface 28h in this order from the tip. The distal end portion 28c is connected to the bottom surface 28h by a pin connection portion 28f and an intermediate portion 28g. The pin connection portion 28f and the intermediate portion 28g are cylindrical and are support members that support the tip portion 28c. The pin connection portion 28f is stored in the ball plunger shell 28b in a state where the distal end portion 28c is not inserted into a pin insertion hole 35 described later, and the distal end portion 28c is inserted into a slide groove 35b described later (particularly a spot facing portion). In the state locked to 35d), it protrudes from the ball plunger shell 28b. The intermediate portion 28g is always stored in the ball plunger shell 28b.

The tip end portion 28c is spherical, and the radius of the maximum cross section (cross section cut parallel to the bottom surface 28h) is larger than the radius of the cross section of the pin connection portion 28f. The radius of the cross section of the intermediate portion 28g is larger than the radius of the cross section of the pin connection portion 28f, and the radius of the cross section of the bottom surface 28h is larger than the radius of the cross section of the intermediate portion 28g.

Furthermore, coil springs 28i (biasing members) are wound around (attached to) the side surfaces of the pin connection portion 28f and the intermediate portion 28g. The coil spring 28i is provided between the bottom surface 28h and the top surface 28d. When the portion of the ball shaft pin 28a that protrudes from the upper surface 28d increases, the coil spring 28i is sandwiched between the upper surface 28d and the bottom surface 28h and is compressed because pressure is applied. Since the coil spring 28i is compressed, a reaction force (biasing force) is generated in the coil spring 28i to return to the original length.

The ball shaft pin 28a may be another type of pin as long as it has a tip 28c.

FIG. 6C is an external view showing an example of a state in which the ball plunger shell 28b is viewed from the side. The ball plunger shell 28b is provided with a spiral portion 28e having a function as a screw portion on a side surface. In the ball plunger shell 28 b, the spiral portion 28 e is fitted with a female screw provided on the mounting surface 25 of the ODU 21, so that the ball shaft pin 28 a is fixed to the ODU 21.

FIG. 6D is an external view showing an example of a state in which the ball plunger shell 28b is viewed from the bottom surface side of the ball plunger shell 28b. A C-shaped ring 28k (retaining ring) is provided on the screw tip surface 28j of the ball plunger shell 28b (the bottom surface of the ball shaft pin 28a and the surface opposite to the side from which the tip 28c protrudes). The C-shaped ring 28k is a ring for fixing the screw tip surface 28j so that the screw tip surface 28j does not come out even when the reaction force of the coil spring 28i is applied to the screw tip surface 28j via the bottom surface 28h.

Referring back to FIG. 4, the configuration of the conversion plate 23 will be described. The conversion plate 23 has a waveguide hole 30 at the center thereof. The waveguide hole 30 is provided so that the waveguide of the ANT 22 is visible when the conversion plate 23 is viewed from the attachment surface 29 side. The waveguide hole 30 is also provided to face the waveguide hole 26 when the ODU 21 is attached to the ANT 22. Due to this configuration, when the ANT 22 is attached to the ODU 21, the waveguide of the ODU 21 and the waveguide of the ANT 22 face each other. For this reason, ODU21 and ANT22 can perform radio | wireless communication via a mutual waveguide.

Furthermore, the conversion plate 23 has a mounting hole 31 in the mounting surface 29. The conversion plate 23 is attached to the ANT 22 by screwing the attachment screw 32 into the attachment hole 31. In FIG. 4, six attachment holes 31 are provided around the waveguide hole 30, but the number is not limited to six and may be other numbers.

FIG. 7A is a perspective view showing an example of the configuration of the ANT 22 and the conversion plate 23 when the conversion plate 23 is attached to the ANT 22. The connection portion 24 of the ANT 22 is provided with six screw holes 36 corresponding to the attachment holes 31 for attaching the attachment screws 32. The operator attaches the conversion plate 23 to the ANT 22 by screwing the attachment screw 32 into the screw hole 36 through the attachment hole 31. The direction in which the mounting screw 32 is screwed is the z direction (direction perpendicular to the surface of the connecting portion 24) in FIG. 7A. The ANT 22 is provided with a waveguide 37 for performing wireless communication with the wireless communication ODU 21. The waveguide hole 30 is provided so that the waveguide 37 can be seen when the conversion plate 23 is viewed from the attachment surface 29 side.

FIG. 7B is a perspective view showing an example of the configuration of the ANT 22 and the conversion plate 23 after the conversion plate 23 is attached to the ANT 22 in FIG. 7A.

Hereinafter, the description of the conversion plate 23 will be continued. In the conversion plate 23, clamp cases 33 are provided at two corners on the diagonal line of the square mounting surface 29. The clamp case 33 has a cylindrical shape and is embedded in the attachment surface 29, and the upper base of the clamp case 33 (the bottom surface of the clamp case 33 on the same side as the attachment surface 29) and the attachment surface 29 are substantially flush with each other. There is a relationship. Here, the two clamp cases 33 are provided at positions facing the two tap portions 27 a on the diagonal line of the ODU 21 when the ANT 22 is attached to the ODU 21.

One clamp case 33 is fixed to the conversion plate 23 by two countersunk screws 34. The clamp case 33 includes a pin insertion hole 35 having a female knife function at the center, and the ODU 21 and the conversion plate 23 are attached by inserting the ball plunger 28 into the pin insertion hole 35.

The same number of pin insertion holes 35 as the ball plungers 28 provided on the ODU 21 are provided on the attachment surface 29. The pin insertion hole 35 is provided at a position corresponding to the ball plunger 28. Specifically, the pin insertion hole 35 is provided at a position where the ODU 21 is attached to the ANT 22 when the distal end portion 28 c is locked to the pin insertion hole 35. Here, the attachment surface 25 and the attachment surface 29 have substantially the same shape (square), and the pin insertion hole 35 is provided on the attachment surface 25 in the attachment surface 29 so that the attachment surface 25 and the attachment surface 29 overlap. The ball plunger 28 is provided at substantially the same position.

Two ball shaft pins 28a and two pin insertion holes 35 are provided in the ODU 21 and the ANT 22, respectively. The distance between the two ball shaft pins 28a and the distance between the two pin insertion holes 35 are equal so that the ODU 21 is locked to the ANT 22 by locking both the ball shaft pin 28a and the pin insertion hole 35. It is comprised so that it may become.

In addition, although the tap part 27 exists in four corners of the attachment surface 25, the ball plunger 28 is mounted | worn with the two tap parts 27a on a diagonal line. In other words, the ball plunger 28 is provided at a position facing the wave guide hole 26. However, the operator may screw the ball plunger 28 into two tap portions 27b on another diagonal line instead of the tap portion 27a. In other words, the operator can move the ball plunger 28 to a position rotated by approximately 90 ° (an angle that can be regarded as 90 ° or substantially 90 °) with respect to the center of the mounting surface 25.

For example, when the polarization of wireless communication in the wireless device 20 is changed from V (vertical polarization) to H (horizontal polarization), the operator starts from the two tap portions 27a to which the ball plunger 28 is currently attached. The ball plunger 28 can be replaced with the other two tap portions 27b. By performing this replacement operation, the ODU 21 can be easily attached to the conversion plate 23 while being rotated 90 degrees from the previous position. Therefore, the operator can easily change the polarization of wireless communication in the wireless device 20 from V (vertical polarization) to H (horizontal polarization). By performing the reverse operation, the polarization of wireless communication can be changed from V (vertical polarization) to H (horizontal polarization). When changing the polarization, the angle of the primary radiator provided in the ANT 22 also needs to be changed by approximately 90 °.

In addition, the tap part 27 may be provided in another place instead of the four corners of the mounting surface 25. In this case, the ball plunger 28 can be moved not to the center of the mounting surface 25 but to a place rotated approximately 90 ° around a predetermined point on the mounting surface 25.

8A and 8B are configuration diagrams showing an example of the configuration of the clamp case 33. FIG. Hereinafter, the configuration of the clamp case 33 will be described.

FIG. 8A is an external view showing an example of the configuration of the front side of the clamp case 33 (the first surface of the clamp case 33 on the attachment surface 29 side). The clamp case 33 is provided with a pin insertion hole 35 and a countersunk screw hole 38. One pin insertion hole 35 is provided at the center of the clamp case 33, and the countersunk screw holes 38 are provided one by one (two in total) across the pin insertion hole 35.

Note that the xyz coordinates in FIG. 8A are defined as follows. In FIG. 8A, the x direction is the direction in which the tip portion 28c is slid (right direction on the paper surface), the y direction is the width direction of the pin insertion hole 35 (depth direction on the paper surface), and the z direction is the tip portion 28c in the pin insertion hole. 35 is a direction (downward direction in the drawing). The −z direction is a direction (upward direction on the paper surface) in which the tip end portion 28 c is removed from the pin insertion hole 35. The x direction, the y direction, and the z direction are directions orthogonal to each other.

The pin insertion hole 35 includes an insertion guide hole 35a, a slide groove 35b, and a terminal end 35c. The insertion guide hole 35a is a circular hole for inserting the distal end portion 28c, and the diameter of the hole is larger than the diameter of the spherical distal end portion 28c. That is, the entire distal end portion 28c can be inserted into the insertion guide hole 35a. The pin insertion hole 35, the insertion guide hole 35a, and the slide groove 35b correspond to the concave portion 15, the insertion hole 16, and the slide hole 17 in the first embodiment, respectively.

The slide groove 35b is a linear groove for sliding the leading end portion 28c inserted into the insertion guide hole 35a and guiding it to the terminal end 35c. Here, the width of the slide groove 35b in the y direction is shorter than the diameter of the tip portion 28c. Therefore, in a state where the distal end portion 28c is slid in the slide groove 35b, the distal end portion 28c is not pulled out in the −z direction from the slide groove 35b (that is, the distal end portion 28c is not pulled out from the clamp case 33). The width of the slide groove 35b in the y direction is longer than the width of the pin connection portion 28f. Therefore, the ball shaft pin 28a can slide in the slide groove 35b in the x direction.

Note that the slide groove 35b is a long hole extending in the x direction in a plan view when the clamp case 33 is viewed from above. An insertion guide hole 35a is provided at one end of the slide groove 35b, and a terminal end 35c is provided at the other end. In other words, the insertion guide hole 35a is provided in the −x direction of the slide groove 35b, and the terminal end 35c is provided in the x direction.

The slide groove 35b is inclined so that the tip 28c moves in the z direction in the x direction. In other words, a gentle taper is provided from the insertion guide hole 35a side to the terminal end 35c side so that the slide groove 35b moves from the front side to the back side of the clamp case 33 (from the ODU 21 to the ANT 22 side). For this reason, when the distal end portion 28c is slid from the insertion guide hole 35a side to the terminal end 35c side, the distal end portion 28c protrudes higher from the upper surface 28d of the ball plunger 28 (that is, protrudes higher in the z direction).

FIG. 8B is an external view showing an example of the configuration of the back side of the clamp case 33 (the second surface of the clamp case 33 opposite to FIG. 8A). The definition of xyz coordinates in FIG. 8B is the same as in FIG. 8A.

8A is provided with a spherical counterbore 35d (counterbore hole) for locking the ODU at the end 35c in FIG. 8A. The counterbore part 35d has a shape in which the spherical tip part 28c is fitted and locked. For example, the curvature of the inner surface of the clamp case 33 in the counterbore portion 35d is cut out to be approximately 1 / r, where r is the radius of the tip portion 28c. When the distal end portion 28c is fitted into the counterbore portion 35d, the distal end portion 28c is locked to the clamp case 33. That is, the ball plunger 28 is locked to the clamp case 33.

In FIG. 4, in the clamp case 33 on the upper right side of the mounting surface 29, the insertion guide hole 35 a is located on the upper left side of the clamp case 33 and the terminal end 35 c is located on the lower right side of the clamp case 33. On the contrary, in the clamp case 33 at the lower left of the mounting surface 29, the insertion guide hole 35 a is located at the lower right of the clamp case 33 and the terminal end 35 c is located at the upper left of the clamp case 33. That is, the insertion guide hole 35a is provided on the attachment surface 29 in a clockwise positional relationship with respect to the terminal end 35c when viewed from the side where the clamp case 33 is provided. Due to this configuration, after the operator inserts the ball plunger 28 into the insertion guide hole 35 a of the clamp case 33, the ODU 21 is rotated clockwise so that each ball plunger 28 is moved to the end 35 c of the respective clamp case 33. It is possible to guide.

Hereinafter, a mechanism when the operator locks the ODU 21 to the conversion plate 23 will be described.

FIG. 9A is a plan view showing an example of the appearance of the wireless device 20 before locking in the configuration of the wireless device 20 shown in FIG. Here, the configuration of the wireless device 20 is as shown in FIG. In other words, FIG. 9A shows an initial state in which the operator has started to lock the ODU 21 to the conversion plate 23 (starting to mount the ODU 21 and the ANT 22 (connection unit 24)). In FIG. 9A, the axis a is the horizontal axis of the conversion plate 23, and the axis b is the vertical axis of the conversion plate 23. The axis c is the vertical axis of the ODU 21. In FIG. 9A, the axis c is inclined 10 ° counterclockwise with respect to the axis b. The connecting portion 24 is connected to the attachment device 90.

FIG. 9B is a cross-sectional view showing an example of the state of the wireless device before locking in the state of FIG. 9A. In FIG. 9B, the x direction is the direction in which the tip 28c is slid (downward on the paper), and the z direction is the direction in which the tip 28c is inserted into the pin insertion hole 35 (leftward on the paper). The x direction and the z direction are directions orthogonal to each other.

The tip 28c of the ball plunger 28 is inserted into the insertion guide hole 35a of the clamp case 33. When the operator locks the ball plunger 28 to the clamp case 33, the operator inserts the tip 28c of the ball shaft pin 28a into the insertion guide hole 35a in this way. The waveguide hole 26 and the waveguide hole 30 are opposed to each other.

From this state, the operator rotates the ODU 21 with respect to the conversion plate 23 by 10 ° in the clockwise direction in FIG. 9A. By this operation, the distal end portion 28c is guided from the insertion guide hole 35a to the terminal end 35c through the slide groove 35b. That is, the ball shaft pin 28a slides along the slide groove 35b and reaches the end 35c. Thus, in each clamp case 33, the front-end | tip part 28c moves to ax direction and az direction.

As described above, the slide groove 35b is gently tapered so that the slide groove 35b is directed from the front side to the back side of the clamp case 33. For this reason, as the rotation angle of the ODU 21 from FIG. 9A increases, the compressive force applied from the upper surface 28d to the coil spring 28i of the ball plunger 28 also increases. For this reason, the reaction force of the coil spring 28i increases.

FIG. 10A is a plan view showing an example of the appearance of the wireless device 20 after being locked. In FIG. 10A, the axis b that is the vertical axis of the conversion plate 23 and the axis c that is the vertical axis of the ODU 21 coincide with each other.

FIG. 10B is a cross-sectional view showing an example of the state of the wireless device 20 after locking in the state of FIG. 10A. The x direction and z direction in FIG. 10B are the same as in FIG. 10A.

The tip portion 28c of the ball plunger 28 is located at the terminal end 35c of the clamp case 33 and is fitted into the counterbore portion 35d. In this state, since the coil spring 28i is compressed to the maximum, the reaction force of the coil spring 28i is maximum. For this reason, the ball plunger 28 is completely locked to the clamp case 33.

Here, since the front end portion 28c is fitted and locked in the counterbore portion 35d (the side surface of the front end portion 28c is in contact with the wall of the counterbore portion 35d), the reaction force of the coil spring 28i toward the ODU 21 side. Is offset by the drag applied to the tip 28c from the wall of the counterbore 35d. Accordingly, a reaction force from the coil spring 28 i to the ANT 22 side is applied to the ball plunger 28.

In addition, what is necessary is just to rotate ODU21 counterclockwise in FIG. 10A, when removing ODU21 from the state locked with ANT22 (unlocking). As a result, the ball shaft pin 28a of the ball plunger 28 is released from the counterbore part 35d, and the tip part 28c passes through the slide groove 35b and reaches the position of the insertion guide hole 35a. That is, the states of ODU21 and ANT22 return to the state shown in FIG. 9A (or FIG. 9B), and ODU1 becomes separable from ANT2. The operator can remove the ODU 21 from the ANT 22 by pulling out the ODU 21 in the direction opposite to the ANT 22 from the state shown in FIG. 9A.

In addition, in each clamp case 33 of the attachment surface 29, the insertion guide hole 35a and the termination | terminus 35c may be provided in the reverse position. In this case, after the operator inserts the ball plunger 28 into the insertion guide hole 35 a of the clamp case 33 and then rotates the ODU 21 counterclockwise, each ball plunger 28 is guided to the terminal end 35 c of the respective clamp case 33. It becomes possible to do. When the operator removes the ODU 21 from the ANT 22, the ODU 21 may be rotated clockwise.

FIG. 11 is a configuration diagram (perspective view) showing an example of the state of the ball plunger 28 and the clamp case 33 after being locked in FIG. 10B. The clamp case 33 faces the back side shown in FIG. 8B toward the front side of the paper surface. The definition of xyz coordinates in FIG. 11 is the same as in FIG. 8A.

The front end portion 28c is located at the end 35c, and the front end portion 28c is fitted in the counterbore portion 35d. The tip 28c is in contact with the side wall of the counterbore 35d. The ball plunger 28 is locked in this state. As described above, the ball plunger 28 and the clamp case 33 constitute a unit that can be attached and detached with one touch. The ball plunger 28 is a male fixing device, and the clamp case 33 is a female fixing device. In FIG. 11, the ball plunger 28 and the clamp case 33 are fitted together.

In FIG. 11, the ball plunger 28 and the clamp case 33 are unlocked by sliding the tip 28c in the −x direction.

The wireless device 20 described above has the following effects.

The wireless device 20 uses the reaction force generated when the coil spring 28i attached to the ball plunger 28 is compressed, thereby allowing the waveguide surface of the ANT 22 and the waveguide surface of the ODU 21 to be in close contact with each other, and at the same time, the ANT 22 And ODU21 can be easily fixed (fastened).

The fixing (fastening) between the ODU 21 and the ANT 22 can be realized by a one-touch attachment / detachment unit (mounting structure) having a clamp function, which includes a ball plunger 28 attached to the ODU 21 and a clamp case 33 attached to the ANT. . Here, the ball plunger 28 has a ball shaft pin 28a (the tip portion 28c thereof) and a coil spring 28i that applies a biasing force of the ball shaft pin 28a in the direction from the ODU 21 to the ANT22. The clamp case 33 is provided continuously to the pin insertion hole 35 into which the distal end portion 28 c can be inserted, and the pin insertion hole 35, holds the distal end portion 28 c so as to be slidable inside, and the distal end portion 28 c from the pin insertion hole 35. The slide groove 35b is inclined so that the urging force of the coil spring 28i increases as it is slid. Due to this configuration, the operator can fix the ODU 21 simply by sliding the ball shaft pin 28a into the slide groove 35b. As a result, the worker can be fixed more easily. Accordingly, the ODU attachment / detachment workability can be greatly improved.

Especially, in the work of attaching / detaching the ODU, the operator can perform the work with only one hand. Therefore, the worker can work easily, and the work efficiency is improved. In addition, even when an operator is working at a high place, he / she can secure his / her own safety with one free hand. As a result, the safety of workers has been greatly improved.

Further, the screwing structure of the wireless device shown in FIG. 12 has the following problems.
-ODU fixing screws and screw fixing tools (hexagonal wrench, etc.) are required to have fall prevention measures from the standpoint of safety measures so that workers do not drop down during fixing work. A separate fee is incurred to take this measure.
-The fixing screw is arranged outside the ODU. Therefore, it is necessary to increase the outer size of the ODU, which makes it difficult to install the ODU in a limited space.

On the other hand, the ODU 21 of the wireless device 20 can be reliably attached and detached without the operator using a tool. When using tools to attach and detach wireless devices, when an operator forgets to hold a tool, it takes extra time to return to the ground from the steel tower, etc. The required time can be shortened. In addition, it is not necessary to take measures against dropping of the tool accompanying the work, and the work cost can be reduced.

Furthermore, the ball plunger 28 and the clamp case 33 necessary for attaching the ODU 21 can be disposed inside the ODU 21. Specifically, the ball plunger 28 is on the back side (attachment surface 25 side) of the ODU 21, and the clamp case 33 is on the attachment surface 29 side of the ANT 22. Therefore, it is not necessary to increase the outer size of the ODU 21, and the operator can install the ODU 21 in a limited space.

Further, the patch device locking structure of the wireless device shown in FIG. 13 has the following problems.
・ Patchon tablets, which are outdoor specifications and require high strength, are quite expensive.
-Since the patch and lock itself is relatively large and is a rugged object, it is difficult to balance the size of the ODU and the size of the patch and the appearance of the wireless device is impaired.
-The operation (fastening and releasing) of the patch and lock requires a space (space) for an appropriate operation around the wireless device, so that there are mounting restrictions on the space around the wireless device.

However, since a patchon lock is not used for attaching / detaching the ODU 21 in the wireless device 20, the price of a unit that can be attached / detached can be suppressed.

Furthermore, the one-touch attachment / detachment unit cannot be seen on the appearance of the wireless device 20 when the ODU 21 is attached to the ANT 22. Therefore, the appearance of the ODU 21 with the ODU 21 mounted on the ANT 22 has a simple and clean design. From this point, the wireless device 20 can improve the appearance design as compared with the wireless device shown in FIG.

Furthermore, since the ODU 21 can be attached / detached by simply sliding (specifically rotating) the ODU 21, the space required for attaching / detaching the ODU 21 in the wireless device 20 is small. Therefore, the wireless device 20 can reduce mounting restrictions compared to the wireless device shown in FIG.

In the configuration of the wireless device described in Patent Document 1, the operator needs to turn a screw when fixing the wireless device. However, in the wireless device 20 according to the second embodiment, since the operator can attach the ODU 21 to the ANT 22 simply by sliding the ODU 21, the work necessary for the attachment becomes easier.

Also, in the connection structure described in Patent Document 2, it is necessary to provide a leaf spring on the side wall side, whereas in the wireless device 20 according to the second embodiment, it is not necessary to provide a spring on the ANT 22 side. Therefore, the space required for the mounting structure on the ANT22 side can be reduced.

Furthermore, the wireless device 20 according to the second embodiment also has the following effects.

In the state where the distal end portion 28c is inserted into the insertion guide hole 35a, the end face of the waveguide of the ODU 21 and the waveguide of the ANT 22 face each other. Therefore, the ODU 21 and the ANT 22 can be easily attached and the wireless device 20 can execute transmission / reception of a wireless signal.

The pin insertion hole 35 includes a counterbore portion 35d for locking the tip portion 28c on the side opposite to the insertion guide hole 35a. Therefore, the operator can slide the tip portion 28c to the counterbore portion 35d and steadily lock the ball plunger 28 (ODU21).

The tip portion 28c is a tip sphere of the ball shaft pin 28a. For this reason, the convex part inserted in the pin insertion hole 35 is realizable with a simple structure.

The ODU 21 includes a screw hole, and a tip end portion 28c is detachably attached to the ODU 21 by a ball plunger shell 28b (screw) screwed into the screw hole. And the supporting member (pin connection part 28f and intermediate part 28g) which supports the front-end | tip part 28c, and the coil spring 28i are accommodated in the inside of the ball plunger shell 28b. Therefore, the operator can easily attach the tip end portion 28c and the coil spring 28i to the ODU 21 by turning the ball plunger shell 28b around the screw hole provided in the ODU 21. Further, since the support member and the coil spring 28i are accommodated inside the ball plunger shell 28b, it is possible to prevent damage or the like at the time of attachment.

The coil spring 28i receives a stronger pressure from the head (upper surface 28d) of the ball plunger shell 28b according to the slide from the insertion guide hole 35a of the tip 28c, and biases the tip 28c in the direction from ODU21 to ANT22. To do. For this reason, since the urging | biasing force can be produced without making the coil spring 28i touch the surface of ANT22, damage etc. of the coil spring 28i can be prevented.

Two ball plungers 28 (particularly the tip portion 28 c) are provided on the attachment surface 25 of the ODU 21, and at least the same number of pin insertion holes 35 as the ball plungers 28 are located on the attachment surface 29 of the ANT 22 corresponding to the ball plunger 28. Provided. Here, in the pin insertion hole 35, each slide groove 35b is provided in a clockwise positional relationship with respect to the insertion guide hole 35a. Therefore, the operator can fix the ODU 21 to the ANT 22 by rotating the ODU 21 clockwise to slide the tip 28c into the slide groove 35b.

In the pin insertion hole 35, each slide groove 35b may be provided in a counterclockwise positional relationship with respect to the insertion guide hole 35a. In this case, in the clamp case 33 on the upper right side of the attachment surface 29, the insertion guide hole 35 a is located on the lower right side of the clamp case 33 and the terminal end 35 c is located on the upper left side of the clamp case 33. Conversely, in the clamp case 33 located on the lower left side of the mounting surface 29, the insertion guide hole 35 a is located on the upper left side of the clamp case 33 and the terminal end 35 c is located on the lower right side of the clamp case 33. The operator can fix the ODU 21 to the ANT 22 by sliding the tip 28c into the slide groove 35b by a simple operation of rotating the ODU 21 counterclockwise. Here, the center of rotation may be the center of the attachment surface 29 or another point.

The slide groove 35b in the pin insertion hole 35 is arranged such that the tip 28c moves from the ODU 21 side to the ANT 22 side from the insertion guide hole 35a side to the side opposite to the insertion guide hole 35a (that is, counterbore portion 35d side). An inclination is provided. For this reason, with a simple configuration, the urging force of the coil spring 28i can be increased as the distal end portion 28c is slid from the insertion guide hole 35a.

Here, in the pin insertion holes 35 of more than half of the plurality of pin insertion holes 35 (for example, when there are two pin insertion holes 35, one or more pin insertion holes 35), the slide groove 35b is inserted into the insertion guide hole 35a. It is desirable to be in a lower position. Because of this configuration, it is possible to prevent the distal end portion 28c that has been slid and locked from returning to the insertion guide hole 35a due to gravity and releasing the lock.

The ball plunger 28 (tip portion 28 c) of the ODU 21 can move to a position rotated by approximately 90 ° with respect to a specific point (for example, the center) of the mounting surface 25 of the ODU 21. Due to this configuration, when changing the polarization of the radio device 20, the ODU 21 can be rotated approximately 90 ° and attached to the ANT 22 simply by moving the ball plunger 28 from the original location to the location. Therefore, when the polarization of the wireless device 20 is changed, the operator needs to perform less operations on the wireless device 20.

It should be noted that the clamp case 33 (pin insertion hole 35) of the ANT 22 may be movable to a location rotated by approximately 90 ° with respect to a specific point (for example, the center) of the mounting surface 29 of the ANT 22. Due to this configuration, when changing the polarization of the wireless device 20, the ODU 21 can be rotated by approximately 90 ° and attached to the ANT 22 by moving the clamp case 33 from the original location to the location. Therefore, when the polarization of the wireless device 20 is changed, the operator needs to perform less operations on the wireless device 20.

In the second embodiment, the wireless device 20 in which the ODU 21 and the ANT 22 are provided in each of the ball plunger 28 and the pin insertion hole 35 has been described. However, any number of ODUs 21 and ANTs 22 can be provided in the ball plunger 28 and the pin insertion hole 35, respectively. For example, only one ODU 21 and ANT 22 may be provided in each of the ball plunger 28 and the pin insertion hole 35.

Alternatively, the ODU 21 and the ANT 22 may be provided in the ball plunger 28 and the pin insertion hole 35 by three or more numbers (three, four,...), Respectively. Even in this case, the same number of pin insertion holes 35 as the ball plungers 28 are provided on the attachment surface 29 of the ANT 22 at positions corresponding to the ball plungers 28. Moreover, in the pin insertion hole 35, each slide groove 35b can be provided in the clockwise or counterclockwise positional relationship with respect to the insertion guide hole 35a. Further, as described above, each ball plunger 28 and the pin insertion hole 35 can be moved to a place rotated by approximately 90 ° with respect to a specific point (for example, the center) of the mounting surface.

The first device provided with the ball plunger 28 (tip portion 28c) is the ODU 21, and the second device provided with the pin insertion hole 35 is the ANT 22. For this reason, the operator can insert the distal end portion 28 c into the pin insertion hole 35 while visually confirming the pin insertion hole 35 of the ANT 22 and confirming its position. Therefore, it is possible to easily perform the attaching operation between the ODU 21 and the ANT 22.

Conversely, the device provided with the ball plunger 28 may be ANT22, and the device provided with the pin insertion hole 35 may be ODU21. However, when attaching the ODU 21 and the ANT 22, it is considered that the operator often attaches the ODU 21 to the original ANT 22. Therefore, in mounting, rather than inserting the ball plunger 28 into the pin insertion hole 35 of the ODU 21 held in the hand while visually checking the ball plunger 28 of the ANT 22, The mounting operation can be facilitated by inserting the ball plunger 28 of the held ODU 21 into the pin insertion hole 35. Even when the tip 28c is slid into the slide groove 35b, it is easier for the operator to perform the mounting operation because the operator tends to slide by holding the ball plunger 28.

Note that the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention. In other words, various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.

For example, in the conversion plate 23 in FIG. 4, the pin insertion holes 35 are provided at the two corners, but the pin insertion holes 35 may be newly provided at the other two corners on the other diagonal line of the conversion plate 23. Good. In this case, in the newly provided pin insertion hole 35, like the other pin insertion holes 35, the respective slide grooves 35b are provided in a clockwise positional relationship with respect to the insertion guide hole 35a. Due to this configuration, the operator can lock the ODU 21 and the ANT 22 by inserting the tip 28 c into the insertion guide hole 35 a of the newly provided pin insertion hole 35 and sliding the ODU 21 clockwise. it can.

In this case, in the ODU 21, it is not necessary to provide the tap portion 27 in a place other than the place where the ball plunger 28 is provided. That is, the ball plunger 28 does not need to move in the ODU 21.

Alternatively, in the ODU 21, the ball plunger 28 may be newly provided also in the tap portion 27b. That is, the ball plunger 28 may be provided at the four corners of the mounting surface 25 of the ODU 21. Because of this configuration, when changing the polarization of the wireless device 20, the operator does not need to change the position of the ball plunger 28 or the pin insertion hole 35 (clamp case 33), but only rotates the direction of the ODU 21 by 90 °. The ODU 21 can be fixed at a position corresponding to the polarization change.

The ODU 21 does not necessarily need to be configured to allow polarization change. That is, the ODU 21 may not be configured to be attached to the ANT 22 in a state where the ODU 21 is rotated by approximately 90 ° from the original attachment position. In that case, in the two pin insertion holes 35 on the mounting surface 29 of the ANT 22, the insertion guide hole 35a is preferably located above the slide groove 35b. This is because the tip portion 28c is reliably locked by the counterbore portion 35d by gravity due to this configuration. In the attachment surface 29, three or more pin insertion holes 35 may be provided. In this case, the more pin insertion holes 35 in which the insertion guide holes 35a are positioned on the slide grooves 35b, the more reliable the locking of the distal end portion 28c is desirable. For example, in all the pin insertion holes 35, the insertion guide holes 35a can be positioned on the slide grooves 35b.

In addition, the configurations of the ball plunger 28 and the clamp case 33 are not limited to the configurations described in the second embodiment. For example, the ball plunger 28 (tip portion 28c) may be fixed to the ODU 21 with another fixing member instead of the ball plunger 28 (screw). In that case, when the tip portion 28c is slid from the insertion guide hole 35a, the coil spring 28i may be configured to receive pressure directly from the mounting surface 29 instead of the upper surface 28d of the ball plunger shell 28b.

The shape of the tip portion 28c may not be spherical, and may be a rectangular parallelepiped, for example. The tip 28c may not be attached to the ball shaft pin 28a.

The shape of the mounting surface 25 in the ODU 21 and the mounting surface 29 in the ANT 22 may not be the shape shown in the second embodiment. Moreover, the attachment surface 25 and the attachment surface 29 do not need to have substantially the same shape. That is, the attachment surface 25 and the attachment surface 29 do not need to overlap.

However, when a plurality of ball shaft pins 28 a and pin insertion holes 35 are provided in the ODU 21 and the ANT 22, the ball shaft pins 28 a and the pin insertion holes 35 are all locked so that the ODU 21 is locked to the ANT 22. The ball shaft pin 28a and the pin insertion hole 35 are provided. That is, the distance between the ball shaft pins 28a and the corresponding distance between the pin insertion holes 35 are all equal.

In Embodiment 2, the device attached to the ANT 22 is the ODU 21, but other wireless devices may be attached to the ANT 22. For example, not the outdoors but a wireless device used indoors or in a base station may be attached to the ANT 22.
