Description

  The present invention relates to a pressure-sensitive mat switch, and more particularly to a pressure-sensitive mat switch that is installed on a floor, a wall, or the like, and detects a suspicious person's intrusion into a monitored building or the like.

  For example, various mat switches are conventionally used for the purpose of detecting the intrusion of a suspicious person into a monitored building or the like, or detecting the presence of an operator in a seat of a work machine.

  A conventional example of such a mat switch will be outlined below.

  A mat switch 40 shown in FIG. 8 includes a plurality of long switches 44 arranged in parallel between upper and lower outer covers 41 and 42 made of, for example, an insulating material formed in a rectangular mat shape. In addition to being connected by the crossover wiring 43, one end of the signal cable 45 is connected to the long switch 44 in the vicinity thereof at the corner positions of the jackets 41 and 42, and acts on the long switch 44 through the jacket 41. The long switch 44 is turned on by an external force, and this on signal is transmitted to a signal monitoring device (not shown) to detect the intrusion of a suspicious person.

  As the long switch 44 constituting the mat switch 40, a pair of long electrode plates 46 and 47 arranged vertically opposite to each other as shown in FIG. 9 are held while forming an insulating space using an insulating material 48 for isolation. In addition, there are known those in which the entirety is surrounded by an insulating jacket 49.

  Further, as shown in FIG. 10, a pair of long pressure-sensitive conductive rubbers 51 and 52 are disposed in the same direction while having an insulating space in a cylindrical insulating jacket 55, and the pressure-sensitive conductive rubber 51, There is also known a long switch 44A in which conductor wires 53 and 54 are inserted into the pressure-sensitive conductive rubber 52, respectively, and are surrounded by an insulating jacket 49.

  However, in the case of the mat switch 40 using the long switch 44 or the long switch 44A, in any case, it is necessary to connect the plurality of long switches 44 or the long switches 44A with the cross wiring 43. As a result, the manufacturing process becomes complicated and the cost increases.

  Moreover, since the area | region between each long switch 44 or each long switch 44A turns into a non-sensing area | region, it was difficult to detect small diameter objects, such as the front-end | tip part of a stick etc. which an intruder holds, for example.

  In order to eliminate such inconvenience, a configuration in which an actuator plate is built in between the adjacent long switch 44 or the long switch 44A is also conceivable. However, in this configuration, the mat switch 40 cannot be folded, and storage and transportation are not possible. Cause inconvenience.

  The mat switch 60 shown in FIG. 11 and FIG. 12 is continuously attached by bending an upper jacket 61 and a lower jacket 62 made of an insulating material, for example, in a rectangular mat shape, and a lower surface of the upper jacket 61. The upper conductor wire 63, the lower conductor wire 64 bent and continuously attached to the upper surface of the lower jacket 62, and the annular shape arranged in a required number between the upper jacket 61 and the lower jacket 62. A perforated insulator 65 and a signal cable 66 having one ends connected to the end portions of the upper conductor line 63 and the lower conductor line 64 are provided. The upper conductor line 63 and the lower conductor line are formed by the annular perforated insulator 65. 64 is configured to maintain insulation between 64.

  In the case of this mat switch 60, it is necessary to dispose a required number of perforated insulators 65 between the upper jacket 61 and the lower jacket 62, which complicates the structure and presents the perforated insulators 65. The place to do becomes an insensitive area.

  The mat switch 70 shown in FIGS. 13 and 14 includes an upper jacket 71, a lower jacket 72 made of an insulating material formed in, for example, a rectangular mat shape, and an upper conductor foil continuously attached to the lower surface of the upper jacket 71. 73, a lower conductor foil 74 continuously attached to the upper surface of the lower jacket 72, an annular perforated insulator 75 arranged in a required number between the upper conductor foil 73 and the lower conductor foil 74, A signal cable 76 having one end connected to a corner portion of the upper conductor foil 73 and the lower conductor foil 74 is provided, and insulation between the upper conductor foil 73 and the lower conductor foil 74 is held by an annular perforated insulator 75. It is comprised as follows.

  Also in the case of the mat switch 70, it is necessary to dispose a required number of perforated insulators 75 between the upper conductor foil 73 and the lower conductor foil 74, which complicates the structure and provides the perforated insulators 75. The place where there exists becomes an insensitive area.

  The mat switch 80 shown in FIGS. 15 and 16 includes an upper outer cover 81 and a lower outer cover 82 made of, for example, a rectangular mat, and an upper conductor plate continuously attached to the lower surface of the upper outer cover 81. 83, a lower conductor plate 84 having a partially convex shape continuously attached to the upper surface of the lower jacket 82, and an annular elastic insulator 85 interposed between the upper conductor plate 83 and the lower conductor plate 84. And a signal cable 86 having one end connected to a corner of the upper conductor plate 83 and the lower conductor plate 84, and a position corresponding to the hole portion of the elastic insulator 85 in the lower conductor plate 84 is a convex shape. The on-operation distance with respect to external force is shortened to improve the sensitivity by reducing the non-sensing part.

  In the case of the mat switch 80, it is necessary to form a required number of convex portions on the lower conductor plate 84, and there is a problem that the structure is complicated and the cost is increased.

  In Patent Document 1, two electrode wires are arranged in parallel at a predetermined interval on the lower surface of the upper jacket, and a current-carrying electric wire is attached to the upper surface of the lower jacket so as to intersect with the two electrode wires at a predetermined interval. There has been proposed a mat switch configured to detect the presence of a person or the like by bringing the electrode wire and the energization wire into contact with each other by a stepping pressure, and not to operate by a stepping pressure by a small animal such as a dog or a cat.

In the case of the mat switch of Patent Document 1, since the two electrode lines are arranged in parallel at a predetermined interval, the non-sensing area is the same as in the case described above.
