JPH065232U - Box for storing wireless devices - Google Patents

Abstract

(57) [Summary] [Structure] The antenna (1) that can be electrically connected to the wireless device (3a) housed in the box body (8) was attached to an appropriate location on the outer surface of the box. [Effect] Since the antenna can be completely exposed to the outside of the box, there is no reduction in gain and stable communication can be performed. In addition, it is possible to prevent cost increase due to hole processing and failure of internal equipment due to intrusion of dust. Further, it is possible to deal with the layout change of the internal equipment, and the maintenance becomes easy.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a box for housing a wireless device such as a specific low-power wireless device exclusively, or for housing it together with an electric device such as a circuit breaker for wiring.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, a hole (10) for drawing out an antenna attached to a wireless device (3a) to the outside of the box body (8) has been formed in the box body.

[0003]

[Problems to be solved by the device]

 With the conventional box, the entire antenna cannot be output to the outside of the box, resulting in a decrease in gain and stable transmission / reception. In addition, the time and effort required to form the antenna extraction hole in the box body contributes to the increase in cost.This is also because the antenna is picked out with the fingers and pulled out to the outside. Is likely to occur, causing insulation failure and causing internal equipment failure. In addition, in the case of a rod-shaped antenna, since the position of the antenna mounting portion of the wireless device and the hole of the box body must be aligned, it is not possible to change the mounting position of the wireless device after processing the hole. Furthermore, if the antenna is damaged, the wireless device must be removed and repaired, which is troublesome.

[0004]

[Means for Solving the Problems]

 The present invention solves each of the problems in the related art, and provides a box for storing a wireless device, which can bring out the performance of the wireless device sufficiently and is highly versatile. That is, the configuration is that an antenna that can be electrically connected to the wireless device housed in the box body is attached to an appropriate location on the outer surface of the box.

[0005]

[Action]

 Since the antenna is attached at an appropriate place on the outer surface of the box, it can be used simply by making an electrical connection with the wireless device inside the box, and the antenna is completely exposed to the outside of the box, reducing the gain. Without, stable communication can be performed.

[0006]

【Example】

 FIG. 1 is an explanatory view of a box for housing a wireless device according to the present invention. The present invention will be described below with reference to the drawings. (3a) is a wireless device, (3b), (3c), (3d) are electrical devices such as a circuit breaker, (8) is a box body, and (7) is a door. (2) is a coaxial cable, one end of which is detachably connected to the terminal (6) of the wireless device and the other end of which is detachably connected to the connector (5). (1) shows an antenna, the base end of which is attached to the metal fitting (1a) rotatably in the direction of the arrow, and the connector (5) is energized. This metal fitting (1a) is insulated from the box body and screwed in the recess (4) so that it can be attached and detached, which facilitates antenna replacement. The connector (5) is, for example, an F-type connector or an M-type connector having a small gain loss. Reference numeral (4) is a recess formed on the upper surface of the box body, which is formed at a depth of at least the diameter of the antenna or more, and can accommodate the rotated antenna (1) as shown in FIG. In this way, the antenna can be attached to the body of the box without making holes, and the orientation of the antenna can be changed freely. In addition, it can be used while being housed in the recess, and if it is housed when not in use, it will not be exposed to the outside of the box and will look good.

[0007] Here, if the coaxial cable has a certain length of allowance, it is possible to cope with a slight change in the mounting position of the wireless device. In addition, the layout of internal equipment can be dealt with by removing the connector and terminal and changing to a long coaxial cable.

The antenna may be of a flexible type and directly connected to the connector, and the metal fitting (1 a) is not limited to that of this embodiment, and the antenna can be rotated as long as it can be rotated. , Other structures may be used.

Further, as shown in FIG. 3, the antenna can be attached to the door (7), and its attaching position is not limited.

FIG. 4 shows a modified embodiment of the present invention. This is a flat antenna (9) mounted on the surface of the door (7) and electrically connected to the wireless device (3). The planar antenna may be attached to the surface of the door or may be embedded so as not to be exposed on the surface. Further, the door surface may be coated with a glass material or the like after being buried.

[0011]

[Effect of device]

 By using the wireless device housing box according to the present invention, the antenna can be completely exposed to the outside of the box, so that stable communication can be performed without lowering the gain. Further, the antenna having a rotatable structure enables more stable communication. Moreover, not only the cost increase due to the hole processing and the failure of the internal equipment due to the intrusion of dust can be prevented, but also the layout change of the internal equipment can be dealt with. Further, the antenna can be housed to improve the appearance, and the antenna can be detached to facilitate maintenance.
