Description

[Technical Field]

[0001] The present disclosure relates to a wiring connection structure of a repeater used when connecting disaster prevention equipment to a fire control panel. [Background technology]

[0002] When connecting terminal devices such as general detectors, district bells, and smoke control and exhaust equipment (fire doors, fire shutters, fire dampers, smoke exhaust vents, etc.) to a composite GR type fire receiver, a connection structure via a repeater may be used (see, for example, non-patent document 1).

[0003] For example, to connect a P-type sensor to an R-type receiver, the signal must be transmitted via a repeater, which requires installing repeaters on the repeater panel and running wiring between the repeaters. [Prior art documents] [Non-patent literature]

[0004] [Non-Patent Document 1] Nohmi Bosai Co., Ltd. website, Composite GR System R-26C System (URL: https: / / www.nohmi.co.jp / product / r_system / R_26C.html) Summary of the Invention [Problem to be solved by the invention]

[0005] This type of crossover wiring work within the repeater panel must be done manually depending on the type and number of terminal devices used in the disaster prevention system, which increases work time and drives up manufacturing costs.

[0006] In addition, the power supply for the repeater must be separated into power lines depending on the type of terminal device connected, which means that the length of the bridging wires is not fixed, making the bridging wire installation even more time-consuming and increasing the installation time.

[0007] Specific examples of wiring in a disaster prevention system will be explained using Figures 6 and 7. Figure 6 is an explanatory diagram showing an example of a conventional technique related to the wiring state in a disaster prevention system in which each terminal device is connected to a fire alarm receiver via a repeater. Also, Figure 7 is an explanatory diagram showing an enlarged view of the wiring state within the repeater panel shown in Figure 6.

[0008] In FIGS. 6 and 7, the following wirings L1a to L4a are shown as main trunk lines. Wiring L1a: Main signal line for connecting the analog detector 1 to the fire receiver 11. Wiring L2a: A power supply wire for the detector that connects the fire receiver 11 to the terminal block T1 in the repeater panel 12. Wiring L3a: District bell power line connecting the fire receiver 11 and terminal block T1 in the repeater panel 12. Wiring L4a: Smoke control power line connecting the fire receiver 11 and the terminal block T1 in the repeater panel 12.

[0009] In addition, in FIGS. 6 and 7, the following wirings L2b to L4b are shown as terminal device wirings. Wiring L2b: Signal line for connecting the general sensor 2 to the terminal block T2 in the repeater panel 12. Wiring L3b: Signal line for connecting district bell 3 to terminal block T2 in repeater panel 12. Wiring L4b: Signal line for connecting the smoke control device 4 to the terminal block T2 in the repeater panel 12.

[0010] Then, within the repeater panel 12, it is necessary to use jumper wiring of various lengths to connect between the terminal block T1 and the terminal block T2 depending on the type and number of terminal devices used in the disaster prevention system. Specifically, it is necessary to have jumper wiring for the main signal line between each repeater, and jumper wiring for the power line between the repeaters for each connected terminal device.

[0011] Therefore, the labor required for wiring such bridging wiring within the repeater panel 12 increases the work time and is a factor that pushes up manufacturing costs.

[0012] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a wiring connection structure for a repeater that can suppress increases in work time and manufacturing costs associated with wiring work. [Means for solving the problem]

[0013] The wiring connection structure of a repeater according to the present disclosure comprises a wiring connection adapter including an external terminal having a main signal line terminal to which a main signal line is connected and a plurality of power line terminals to which each of a plurality of power lines is connected, and a pattern member on which a main signal line pattern connected to the main signal line terminal and a plurality of power line patterns connected to each of the plurality of power line terminals are provided, and a repeater having a selective connection structure capable of selectively inputting the main signal line pattern and a desired power line pattern which is one of the plurality of power line patterns, and by attaching the repeater to the wiring connection adapter, the main signal line pattern and the desired power line pattern are input, enabling the desired transmission operation according to the connection target. [Effects of the Invention]

[0016] Hereinafter, preferred embodiments of the wiring connection structure for a repeater according to the present disclosure will be described with reference to the drawings. The wiring connection structure of the repeater according to the present disclosure has a technical feature in that it eliminates the need for crossover wiring work by using a wiring connection adapter with a wiring pattern and a repeater having a selective connection structure that can selectively input a desired main signal line pattern and a desired power line pattern.

[0017] Embodiment 1 1 is an explanatory diagram showing an example of a wiring state in a disaster prevention system to which the wiring connection structure of a repeater according to the first embodiment of the present disclosure is applied. The wiring L1a to wiring L4a, wiring L2b to wiring L4b, analog detector 1, general detector 2, district bell 3, smoke control device 4, fire receiver 11, and repeater panel 12 shown in FIG. 1 are the same as those described in the conventional disaster prevention system shown in FIG.

[0018] 1 according to the present embodiment 1 differs from the configuration of Fig. 6 in that it employs a wiring connection structure of the repeater that eliminates the need for crossover wiring work within the repeater panel 12. Therefore, this characteristic wiring connection structure of the repeater according to the present embodiment 1 will be described in detail with reference to Figs. 2 to 5.

[0019] 2 is an explanatory diagram showing a detailed configuration of a wiring connection structure of a repeater according to the first embodiment of the present disclosure. The wiring connection structure of a repeater according to the first embodiment is configured to include a wiring connection adapter 100 and a plurality of repeaters 200.

[0020] 3 is an explanatory diagram relating to a specific configuration of repeater 200 to which the wiring connection structure of a repeater according to embodiment 1 of the present disclosure is applied. Furthermore, FIG. 4 is an explanatory diagram relating to a specific configuration of wiring connection adapter 100 to which the wiring connection structure of a repeater according to embodiment 1 of the present disclosure is applied.

[0021] As shown in FIGS. 2 and 4, the wiring connection adapter 100 includes an external line terminal 110, a pattern member 120, a third connector 131, and a fourth connector 132.

[0022] The external line terminal 110 is configured to include a main signal line terminal 111 to which the line L1a serving as the main signal line is connected, and a power line terminal 112 to which the lines L2a to L4a serving as various power lines are connected.

[0023] The pattern member 120 is configured to include a main signal line pattern 121 and a power line pattern 122. The pattern member 120 can be configured as a substrate or a sheet member on which the main signal line pattern 121 and the power line pattern 122 are arranged.

[0024] When the pattern member 120 is configured as a substrate, the substrate may be divided into a predetermined number of repeaters 200 at a predetermined length in the vertical direction of Figure 2, and may be configured so that the substrate can be fitted together vertically to extend to the desired length.

[0025] Furthermore, when the pattern member 120 is configured as a sheet member, it may be configured such that a long sheet member in the vertical direction of FIG. 2 can be cut to an appropriate length for use.

[0026] The main signal line pattern 121 is connected to the main signal line terminal 111, and is patterned with signal lines that are electrically connected to the wiring L1a that is connected to the main signal line terminal 111. The power supply line pattern 122 is connected to the power supply line terminal 112, and is patterned with various power supply lines that are electrically connected to the wiring L2a to wiring L4a that are connected to the power supply line terminal 112.

[0027] Furthermore, the surfaces of the main signal line pattern 121 and the power line pattern 122 provided as the pattern member 120 can be covered with an insulating member 123 .

[0028] 4, the first embodiment illustrates a case in which two wirings, "main signal line 1" and "main signal line 2," are patterned to form a main signal line pattern 121, and three wirings, "detector power supply," "area bell power supply," and "smoke control power supply," are patterned to form a power line pattern 122. However, the number of wirings is not limited to this example.

[0029] However, the following description will be made on the assumption that the main signal line pattern 121 is made up of two wires and the power supply line pattern 122 is made up of three wires, as shown in FIG.

[0030] The repeater 200 has a selective connection structure that can selectively input a desired main signal line pattern, which is one of the two main signal line patterns 121, and a desired power line pattern, which is one of the three power line patterns 122.

[0031] This "selective connection structure" is realized by a repeater 200 having a first connector 201 and a second connector 202, as shown in Fig. 3. The first connector 201 can be configured as a first convex portion, and the second connector 202 can be configured as a second convex portion.

[0032] First connector 201 is configured to be movable to a desired position, either position P11 or position P12, while second connector 202 is configured to be movable to a desired position, either position P21, position P22, or position P23.

[0033] 4, the wiring connection adapter 100 has a third connector 131 and a fourth connector 132. The third connector 131 can be configured as a first recess so as to mate with the first connector 201 configured as a first convex portion, and the fourth connector 132 can be configured as a second recess so as to mate with the second connector 202 configured as a second convex portion.

[0034] The third connectors 131 are arranged on the main signal line patterns 121, and mate with the first connectors 201 so that, when the first connectors 201 are inserted, electrical connection between the first connectors 201 and the desired main signal line patterns 121 is possible.

[0035] Similarly, the fourth connector 132 is arranged on each of the power line patterns 122, and when the second connector 202 is inserted, it engages with the second connector 202 so as to enable electrical connection between the second connector 202 and the desired power line pattern 122.

[0036] When the surfaces of the main signal line pattern 121 and the power line pattern 122 are covered with an insulating member 123, the first connector 201 and the second connector 202 are inserted through a slit in the insulating member 123. In this way, the desired main signal line pattern 121 and the desired power line pattern 122 arranged below the insulating member 123 are input to the repeater 200 via the selective connection structure.

[0037] With reference to FIG. 4, positions P11, P12, P21, P22, and P23 in FIG. 3 correspond to the following positions, respectively. Position P11: corresponds to a position suitable for fitting the first connector 201 with the third connector 131 provided on the "main signal line 1," which is one of the main signal line patterns 121. Position P12: corresponds to a position suitable for fitting the first connector 201 with the third connector 131 provided on the "main signal line 2," which is one of the main signal line patterns 121.

[0038] Position P21: corresponds to a position suitable for fitting the second connector 202 with the fourth connector 132 provided on the "sensor power supply" which is one of the power line patterns 122. Position P22: corresponds to a position suitable for fitting the second connector 202 with the fourth connector 132 provided on the "district bell power supply" which is one of the power line patterns 122. Position P23: corresponds to a position suitable for fitting the second connector 202 with the fourth connector 132 provided on the "smoke prevention power supply" which is one of the power line patterns 122.

[0039] As shown in Figure 3, the repeater 200 of this embodiment 1 has a "selective connection structure" that allows the first connector 201 to be positioned at position P11 or position P12, and the second connector 202 to be positioned at any of positions P21 to P23.

[0040] Therefore, specific connection examples that apply the "selective connection structure" that is a feature of the wiring connection structure of the repeater of the present disclosure will be described below. Fig. 5 is an explanatory diagram showing first to fourth connection examples that apply the "selective connection structure" that is a feature of the repeater according to embodiment 1 of the present disclosure.

[0041] The first connection example shows a state in which the repeater 200 is screwed onto a substrate formed as a pattern member 120 after the first connector 201 is positioned at position P11 and the second connector 202 is positioned at position P21. As a result, a main signal line pattern 121 corresponding to the "main signal line 1" and a power line pattern 122 corresponding to the "sensor power supply" can be easily input to the repeater 200 without performing a transition wiring.

[0042] The second connection example shows a state in which the repeater 200 is screwed onto a substrate formed as a pattern member 120 after the first connector 201 is positioned at position P11 and the second connector 202 is positioned at position P22. As a result, a main signal line pattern 121 corresponding to the "main signal line 1" and a power line pattern 122 corresponding to the "area bell power supply" can be easily input to the repeater 200 without performing a transition wiring.

[0043] The third connection example shows a state in which the repeater 200 is screwed onto a substrate formed as a pattern member 120 after the first connector 201 is positioned at position P11 and the second connector 202 is positioned at position P23. As a result, a main signal line pattern 121 corresponding to the "main signal line 1" and a power line pattern 122 corresponding to the "smoke prevention power supply" can be easily input to the repeater 200 without performing a transition wiring.

[0044] The fourth connection example shows a state in which the repeater 200 is screwed onto a substrate formed as a pattern member 120 after the first connector 201 is positioned at position P12 and the second connector 202 is positioned at position P23. As a result, a main signal line pattern 121 corresponding to the "main signal line 2" and a power line pattern 122 corresponding to the "smoke prevention power supply" can be easily input to the repeater 200 without performing a transition wiring.

[0045] That is, the repeater 200 has a selective connection structure configured to have a mechanism that can move the position of the first connector 201 to match one of the respective positions (position P11, position P12) of the multiple third connectors 131, and a mechanism that can move the position of the second connector 202 to match one of the respective positions (position P21, position P22, position P23) of the multiple fourth connectors 132.

[0046] It should be noted that the selective connection structure of the repeater 200 according to the present disclosure is not limited to this structure.

[0047] The repeater 200 may be configured with a selective connection structure in which the first connector 201 is configured as a plurality of first connectors 201 to correspond to the respective positions (position P11, position P12) of the plurality of third connectors 131, and each of the plurality of first connectors 201 has a selectable mechanism that allows it to be displaced between an engagement position for engaging with the third connector 131 and a non-engagement position for not engaging with the third connector 131.

[0048] Similarly, the repeater 200 may be configured with a selective connection structure in which the second connector 202 is configured as a plurality of second connectors 202 to correspond to the respective positions (position P21, position P22, position P23) of the plurality of fourth connectors 132, and each of the plurality of second connectors 202 has a selectable mechanism that allows it to be displaced between an engagement position for engaging with the fourth connector 132 and an unengaged position for not engaging with the fourth connector 132.

[0049] In addition, the first connector 201 may be configured as a plurality of first connectors to form a selectable mechanism, and the second connector 202 may be configured as a single connector to form a movable mechanism, thereby forming a selective connection structure by combining a selectable mechanism and a movable mechanism.

[0050] Conversely, the first connector 201 may be configured as a single movable mechanism, and the second connector 202 may be configured as multiple second connectors as a selectable mechanism, and a selective connection structure may be constructed by combining a selectable mechanism and a movable mechanism.

[0051] In this way, the repeater 200 can select and input a desired pair of main signal line patterns 121 and a desired pair of power line patterns 122, thereby enabling the desired transmission operation according to the type of each terminal device used in the disaster prevention system, i.e., according to the connection target.

[0052] For example, in order to connect to the desired power line pattern, the second connector 202 is usually moved to the desired position in advance at the time of shipment from the factory, depending on the type of repeater 200, or the second connector 202 is displaced to the mating position at the desired position.

[0053] If one main signal line can accommodate up to a maximum of 255 addresses, and a disaster prevention system can be constructed with up to 255 addresses, then one main signal line will be sufficient. In this case, therefore, first connector 201 can be fixed at position P11 without moving, and the selective connection structure can be such that only second connector 202 is a movable or selectable mechanism.

[0054] As described above, according to the first embodiment, a wiring connection structure for a repeater is configured using a wiring-patterned wiring connection adapter and a repeater having a selective connection structure that can selectively input a desired main signal line pattern and a desired power line pattern. As a result, it is possible to eliminate the need for crossover wiring work, and to suppress increases in work time and manufacturing costs associated with wiring work.

[0055] As an example, by applying the wiring connection structure of the repeater disclosed herein to wiring work in a factory, the conventional crossover wiring work becomes unnecessary, and it becomes possible to respond simply by installing multiple repeaters with selective connection structures depending on the configuration of the disaster prevention system.

[0056] Furthermore, even if it becomes necessary to add repeaters at the site, there is no need for daisy-chain wiring work, so it is possible to achieve the effect of suppressing increases in work time and manufacturing costs associated with wiring work both at the factory and on site.

[0057] In the above-described embodiment, an electrical interconnection is achieved by fitting a repeater to a wiring connection adapter, but the electrical connection between the wiring connection adapter and the repeater may be achieved by a method other than fitting, and other methods for attaching a repeater to a wiring connection adapter may be adopted.
