[0030] Figure 1 is a schematic diagram of the overall structure of the device expansion circuit board shown in the exemplary embodiments of the present application, as shown in Figure 1 The device expansion circuit board includes a circuit board body 1.

[0031] The circuit board body 1 can be composed of multiple layers of insulating plates, such as plastic plates, rubber plates, and silica gel plates.

[0032] For example, the present application is described using three layers of insulating plates, and the connection between the insulating plates can be adhesive, heat fusion, or multiple layers of casting based on a casting model, etc.

[0033] The circuit board body 1 includes a host connection portion 11 and a device connection portion 12.

[0034] The host connection portion 11 is installed at a position corresponding to the control panel of the fire alarm host, for example, on the key panel.

[0035] The device connection portion 12 is used to connect with the expansion device outside the fire alarm host, for example, a remote control device.

[0036] The host connection portion 11 and the device connection portion 12 can be integrally formed, or can be independent and connected. When they are independent, they can be fixedly connected or detachably connected. The fixed connection can be adhesive or heat fusion, and the detachable connection can be buckle connection or plug-in connection. In other embodiments, the host connection portion 11 and the device connection portion 12 are integrally formed.

[0037] It should be noted that the keys of the control panel on the fire alarm host are the main way to control the fire host, and the fire alarm host is manufactured according to the national standard. In order not to damage the original line structure of the fire alarm host, the device expansion line board is arranged at the key of the control panel on the fire alarm host, so as to control the fire alarm host through other expansion devices, for example, remote control. This measure can also reduce the equipment failure and other problems caused by line transformation of the fire alarm host.

[0038] Based on this, the host connecting part 11 is provided with a positioning hole 111, and the layout of the positioning hole 111 is consistent with the layout of the keys of the control panel on the fire alarm host.

[0039] For example, the fire alarm host is provided with a key A and a key B. If the device expansion line board of the present application needs to be expanded based on the key A and the key B, two positioning holes 111 will be arranged on the host connecting part 11, and when the host connecting part 11 is installed on the fire alarm host, the positions of the two positioning holes 111 are respectively aligned with the positions of the key A and the key B.

[0040] Further, the device connecting part 12 is provided with a connecting terminal 121.

[0041] The arrangement of the connecting terminal 121 can make the connection of the line more neat and convenient, for example, if multiple independent connecting terminals are needed, multiple connecting terminals can be arranged on the connecting terminal 121 in a certain order, so as to facilitate the identification of different connecting terminals during connection.

[0042] Further, the host connecting part 11 and the device connecting part 12 are internally connected with a wire 13, one end of the wire 13 is arranged close to the positioning hole 111, and the other end of the wire 13 is connected with the connecting terminal 121.

[0043] The wire 13 has multiple wires, which are determined according to the actual number of keys that need to be controlled on the fire alarm host. If different wires 13 may cross in the line layout, different wires 13 can be located in different insulating plate interlayers of the line board body 1.

[0044] Illustratively, the keys of the control panel on the fire alarm host are provided with welding points, and the wire 13 at the positioning hole 111 is used to connect with the welding points. The end of the wire 13 connected with the connecting terminal 121 is used to connect with the expansion device outside the fire alarm host.

[0045] Based on the above technical scheme, the probability of internal circuit confusion caused by the newly added wire when connecting the expansion device of the fire alarm host can be reduced, the disassembly and assembly convenience of the expansion device can be improved, and the later fire maintenance is facilitated.

[0046] In some embodiments of the application, based on the other embodiments described above, Figure 2 is an enlarged view of the positioning hole shown in the exemplary embodiments of the application, as Figure 2 shown, in order to improve the reliability and convenience of the wire connection at the positioning hole 111. The end of the wire 13 close to the positioning hole 111 is provided with a welding tab 14, and the welding tab 14 is provided with a welding notch 141, wherein the welding tab 14 is used to connect with the key solder joint of the control panel of the fire alarm host.

[0047] The welding tab 14 can effectively increase the contact area of the solder joint of the wire 13, so that it can be better connected with the key solder joint.

[0048] Figure 3 is an enlarged view of the positioning hole shown in another exemplary embodiment of the application, as Figure 2 and Figure 3 shown, it is particularly noted that the welding notch 141 provided on the welding tab 14 can be a closed notch or an open notch. In use, when the welding tab 14 is aligned with the key solder joint of the control panel of the fire alarm host and the key solder joint can be exposed from the welding notch 141, the connection stability of the welding tab 14 can be improved.

[0049] In some embodiments of the application, based on the other embodiments described above, the wire 13 includes a control wire and a common wire, wherein the number of the control wire, the common wire and the positioning hole 111 is determined according to the key wiring of the control panel of the fire alarm host.

[0050] Exemplarily, for example, the control panel of the fire alarm host has three keys, which are a first key, a second key and a third key.

[0051] The first key has two solder joints a and b;

[0052] The second key has two solder joints c and d;

[0053] The third key has two solder joints e and f.

[0054] Among them, the wire corresponding to the solder joint a and the solder joint e is the same wire, the wire corresponding to the solder joint c and the solder joint f is the same wire, and the solder joint b and the solder joint d are connected by two independent wires.

[0055] Then, the wire corresponding to the solder joint a and the solder joint e can be provided on the device expansion circuit board of the application by a common wire, the wire corresponding to the solder joint c and the solder joint f can also be provided on the device expansion circuit board of the application by a common wire, and the solder joint b and the solder joint d need to be provided on the device expansion circuit board of the application by two independent control wires.

[0056] Therefore, when manufacturing the device expansion circuit board, it is only necessary to extend the host connecting part 11 to the positions corresponding to the first and second keys and set two positioning holes 111 to be aligned with the first and second keys respectively; and the host connecting part 11 does not need to be extended to the position corresponding to the third key, and a corresponding positioning hole 111 does not need to be set to be aligned with the third key.

[0057] Through the above technical solution, on the one hand, the wire 13 and the welding point in the technical solution of the application can be reduced, and on the other hand, the raw materials of the device expansion circuit board can be saved.

[0058] In some embodiments of the application, based on the above other embodiments, Figure 4 is an exploded view of the sub-mother plug connector shown in the exemplary embodiments of the application, as Figure 4 As shown, the wire 13 is provided with a sub-mother plug connector 2 at one end close to the connecting terminal 121. Among them, the connecting terminal 121 is connected with the sub plug connector of the sub-mother plug connector 2, or the connecting terminal 121 is connected with the mother plug connector of the sub-mother plug connector 2.

[0059] When the connecting terminal 121 is connected with the sub plug connector of the sub-mother plug connector 2, the mother plug connector of the sub-mother plug connector 2 can be installed on the expansion device outside the fire alarm host, and when used, the expansion device is directly installed in the form of plugging, thereby improving the use convenience of the device expansion circuit board. Similarly, when the connecting terminal 121 is connected with the mother plug connector of the sub-mother plug connector 2, the sub plug connector of the sub-mother plug connector 2 can be installed on the expansion device outside the fire alarm host.

[0060] Exemplarily, the sub-mother plug connector 2 can be a DuPont connector.

[0061] In some embodiments of the application, based on the above other embodiments, in order to improve the connection stability of the sub-mother plug connector 2, the sub-mother plug connector 2 of the application is provided with an anti-falling buckle 21.

[0062] The anti-falling buckle 21 can be arranged on the side of the sub-mother plug connector 2, and when the sub-mother plug connector 2 is connected, it is fixed by clamping.

[0063] In some embodiments of the application, based on the above other embodiments, the host connecting part 11 and / or the device connecting part 12 of the application is a flexible material.

[0064] In some embodiments of the application, based on the above other embodiments, the host connecting part 11 and / or the device connecting part 12 of the application is a rigid material.

[0065] Specifically, the materials used by the host connecting part 11 and the device connecting part 12 can be the same or different.

[0066] For the technical solutions of the present application, the host connection part 11 and the device connection part 12 are preferably made of the same material, for example, an integrally formed FPC flexible plastic sheet.

[0067] When the host connection part 11 and the device connection part 12 are made of flexible material, the device expansion circuit board can be freely bent, wound, and folded, adapting to complex three-dimensional space layout, supporting dynamic bending without breaking, and being suitable for curved or special-shaped devices. At the same time, compared with traditional rigid circuit boards, FPC flexible plastic sheets have thin thickness and light weight, meeting the needs of miniaturization and light weight.

[0068] It should be noted that the host connection part 11 and the device connection part 12 of the present application are preferably made of flexible material, but in some use scenarios, they can also be made of an integrally formed rigid plate material.

[0069] For the manufacturing materials of the host connection part 11 and the device connection part 12, there are various collocation methods when different manufacturing materials are used. For example, the host connection part 11 is made of flexible material, and the device connection part 12 is made of rigid material. For another example, the host connection part 11 is made of rigid material, and the device connection part 12 is made of flexible material.

[0070] It should be noted that the circuit board body 1 can be made of insulating material. If the circuit board body 1 is not made of insulating material, the conductive wire 13 located in the circuit board body 1 should have an insulating shell.

[0071] In some embodiments of the application, based on the above other embodiments, the host connection part 11 is provided with a connecting piece 3, and the connecting piece 3 is connected with the fire alarm host.

[0072] The connecting piece 3 can be a detachable buckle, a threaded assembly; the connecting piece 3 can also be a fixed connecting structure, such as a welding block.

[0073] Through the setting of the connecting piece 3, the installation stability of the device expansion circuit board can be improved.

[0074] In some embodiments of the application, based on the above other embodiments, Figure 5 is a cross-sectional view of the device expansion circuit board of the exemplary embodiment of the present application located at the host connection part, as Figure 5 shown, the connecting piece 3 of the present application is an adhesive plate 31 with adhesion, and the dustproof sticker 32 is arranged on the side of the adhesive plate 31 away from the host connection part 11.

[0075] The sticking plate 31 is similar to double-sided adhesive tape, one plate surface of the sticking plate 31 is fixedly connected with the host connecting part 11. When it is needed to install the host connecting part 11, the dustproof sticker 32 of the other plate surface of the sticking plate 31 is torn off and is stuck to the corresponding position on the control panel of the fire alarm host.

[0076] The dustproof sticker 32 can effectively prevent dust from adhering to the sticking plate 31, thereby reducing the influence of the adhesion of the sticking plate 31 in the transportation process; meanwhile, the setting of the sticking plate 31 improves the installation convenience of the host connecting part 11. In the description of the present specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "one implementation", "one preferred implementation" or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are contained in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example.
