Description

  The present invention relates to a connector box used in a timing system of a measuring device that measures the result of an athletic competition, and in particular, a connector that covers the connector box with an upper lid and a lower lid and protrudes from the upper lid by a simple operation. The present invention relates to a box device.

  The recent track and field competition is an athletic competition competing for a record of the hundredth of a second, and measurement with electronic instrumentation is essential for official records.

  As shown in bold lines in FIG. 7 or FIG. 8, cable lines for various telecommunication facilities such as time measuring equipment, income equipment, computer equipment, light-emitting display equipment, power supply equipment, etc. are previously provided in the basement of the athletic stadium 100. Wiring made of (hereinafter referred to as “main line 101”) is embedded and constructed. In addition, a large hole is provided at an appropriate position so that a worker who is said to be “Oiso” can enter and exit. A connector box is provided in the hole, and the connector box and the main line 101 are connected by a cord. In addition, a small hole called “hand hole” may be provided in the vicinity of the large bowl. In this case, a connector box is provided in the hand hole, and the cord branched through the large bowl is placed in the hand hole. Connected to the connector box installed in

  In any case, since a connector box has been conventionally installed on the wall in the hall, preparation work for connecting the electronic instrument and the connector box has been difficult. Specifically, the operator crouched, bent the upper body greatly, put his hand into the hole, and performed the required operation on the connector box.

  In track and field events, the measurement preparation work must be done quickly in order to speed up the progress of the competition. However, such a posture is not only painful, but also has a drawback that it takes time to operate because the connection box of the connector box is seen from the other side of the hand.

  In addition, since there is a lot of moisture in the hall, the burden of maintenance on the connector box that hates moisture was heavy.

  Furthermore, conventionally, when connecting a cord to the connector box, the cover plate covering the hole is shifted, and the cord connected to the electronic instrument meter enters the hole through the gap formed between the cover plate and the hole. I was letting. The cover plate usually has a height of about 6 cm to 7 cm, and if it appears on the ground due to the shifting, the presence of the cover plate has had a great influence on the competitors.

  In other words, since the track and field competition is intense, athletes are overly sensitive and tend to hate foreign objects in the stadium. For this reason, it is required that foreign matter does not protrude into the stadium, but the conventional connector box device has not sufficiently met such a request.

  In order to meet such various requests, the applicant made the following invention.

  The upper lid 5 includes an upper lid body 5a and a window lid 15, and is formed in a box shape having a square in plan view (530 mm × 530 mm in this example) and a height of 64 mm, and a window portion 13 is provided on one side. The size of the window portion 13 is formed so as to allow the connector box 1 to enter and exit. In this example, the size of the window portion 13 is 310 mm × 218 mm.

  The upper lid body 5 a is provided with a removable window lid 15 (shown in FIG. 4) that covers the window portion 13, and a small lid 17 that can be opened and closed inward by a hinge 16 on the window lid 15. Reference numeral 15a denotes a finger hole used for attachment / detachment. The small lid 17 is formed in a size of 39 mm × 70 mm, and forms a cord port 18 when it can be bent. Reference numeral 19 denotes an upper surface material made of urethane rubber stretched on the surface of the upper lid 5, specifically the surfaces of the upper lid body 5 a and the window lid 15. The upper lid 5 and the ground surface 21 are flush with the upper surface material 19 provided on the surface of the upper lid 5 and the ground surface 21 when the upper lid 5 is closed.

  The lower lid 7 is formed in a box shape having a square shape in the plan view (534 mm × 534 mm in this example) and a height of 67 mm, a frame 7 a is formed on four sides, and a bottom surface 7 b is opened. Reference numeral 7 c denotes an anchor provided on the opposite side and is embedded in the concrete constituting the hand hole 9.

  As shown in bold lines in FIG. 7 or FIG. 8, the main line made up of cable wires for various telecommunication equipment such as time measuring equipment, income equipment, computer equipment, light display equipment, power supply equipment, etc. 101 is buried and constructed. A hand hole 9 is provided at an appropriate place, and the connector box 1 connected to the main line 101 is embedded in the hand hole 9. Reference numeral 23 denotes a cord connected to, for example, a photo determination timing device. When the cord 23 is connected to the connector box 1, the preparation work for the competition is completed.

  Next, the procedure of this preparation work will be described. First, the window lid 15 of the upper lid 5 is removed, and the window portion 13 is set to “open” (FIG. 6). Next, the connector box 1 is raised by holding the handle 1b of the connector box 1 (FIG. 1B). Next, for example, the cord 23 connected to the photo determination timing device is connected to a predetermined connection portion of the connector box 1. Next, the connector box 1 is brought down to the impact state shown in FIG.

  Next, the window lid 15 is attached to the window portion 13. At this time, the small lid 17 is bent downward to make the cord port 18 “open”, and the cord 23 connected to the photo determination timing device is taken out from the cord port 18. This completes the setting. At this time, the upper surface material 19 provided on the surface of the upper lid 5 and the ground surface 21 are flush with each other.

Therefore, the mounting surface of the connector box 1 is flush with the upper surface material 19 and the ground surface 21, so there is no intimidating feeling to the player due to the protrusion of the connector box 1, and the competition is not affected.

  In addition, since no foreign matter protrudes into the stadium and the cord port 18 is not an opening that may cause the foot to fall off, there is no possibility of falling or other unforeseen circumstances when the person concerned prepares for measurement. Therefore, preparation work can be performed quickly and efficiently, contributing to the progress of the competition.

  Furthermore, the connector box 1 is in a state in which a frame edge that is likely to enter rainwater is covered with the upper lid 5 and the lower lid both during storage and operation when not in use, so that the connector box 1 is protected from moisture. effective. Therefore, there is an effect that the maintenance burden of the connector box is reduced by approximately 80%.

  When it is necessary to perform maintenance or repair of the connector box 1, the cord 11 is removed from the connector box 1, and the upper lid body 5a can be removed from the entire apparatus with the connector box 1 attached, and sent to the factory. Work efficiency is improved.

  As the connector box 1 is moved, a load is also applied to the cord 11 connected to the connector box 1, but the cord 11 is covered with a bellows-like cover 2 at the base where the load is applied. The load on is reduced.

  Further, in the present embodiment, the connector box 1 is substantially covered with the upper lid 5 and the frame edge where rainwater can easily enter in the hand hole 9 except that the small lid 17 is small and “open” during measurement operation. The connector box 1 is closed by the lower lid 7 and the upper lid 5. Therefore, even when it becomes rainy during the competition, it is possible to substantially prevent the intrusion of rainwater. In addition, since the bottom surface 7b of the lower lid 7 is open, even if a slight amount of rainwater permeates through the gap of the small lid 17 or the like, such moisture does not accumulate in the lower lid 7 and enters the hand hole 9. Let it flow out. Therefore, the influence of moisture on the connector box 1 can be greatly reduced. In this case, the water that has flowed into the hand hole 9 may be removed by removing the upper lid 5 and drying the hand hole 9 in fine weather.

  The connector box device according to the present invention is not limited to the above-described embodiment. For example, the hole to which the connector box 1 is applied is not limited to a hand hole, but can also be applied to a large hole referred to as “Oiso”. In such a case, there is no need to provide a hand hole, which contributes to further cost reduction of the track and field stadium equipment cost.

  In the case of the above-described embodiment, since it is assumed that it is installed in an existing hand hole, the bottom surface 7b of the lower lid 7 is formed open, but the bottom surface 7b of the lower lid 7 may be formed closed. . In this case, the height of the hole does not need to project deeply as in the illustrated example, and can be a shallow hole about the height of the lower lid 7 and the upper lid 5 that house the connector box 1. Further, in this case, since the hermeticity of the container composed of the lower lid 7 and the upper lid 5 is further increased, the effect of preventing moisture is further increased, and the construction labor and the execution efficiency are further improved, which is desirable.

  The upper surface material 19 can be made of an appropriate material having the same quality as the ground surface material, and may be, for example, an artificial turf.

  The size of the hole is not limited to the above embodiment, and it is naturally applicable to a hand hole of, for example, 600 mm × 600 mm × 600 mm. As described above, it can also be applied to other holes.

  The electrical / electronic instrument connected to the connector box 1 is arbitrary. In addition to the above, there are an anemometer, an anemometer, a camera, and the like.

  The connector box device according to the present invention is used for telecommunications equipment construction in an athletic stadium.
