The present invention relates to a mounting base, in particular to a mounting base for detachable fixing of a detection or alarm device; for example, a mounting base for detachable fixing of a smoke detector, for connecting a wire of a fire terminal controller to the smoke detector.

A smoke detector can send detected fire information to a fire control terminal, and receive control signals from the fire control terminal. The smoke detector is provided therein with a control circuit board on which a controller is provided, this controller being used to send fire information to the fire control terminal, and to control the actions of the whole smoke detector according to commands from the fire control terminal. The control circuit board of the smoke detector is connected to the fire control terminal by a wire, a wiring assembly for connecting the control circuit board to the wire being provided in the smoke detector; the wire is fixed to the wiring assembly by way of a bolt, with the result that it requires time and effort to connect the wire to the wiring assembly, and to detach it therefrom.

An object of the present invention is to provide a mounting base for detachable fixing of a detection or alarm device, in order to simplify the connection of the wire to the wiring assembly, and the detachment thereof.

The above-mentioned characteristics, technical features, advantages and embodiments of the mounting base for detachable fixing of a detection or alarm device are illustrated further below by describing preferred embodiments in a clear and easily comprehensible way with reference to the accompanying drawings.

In order that the technical features, objects and effects of the invention may be understood more clearly, particular embodiments of the present invention will now be described with reference to the accompanying drawings, in which identical labels represent identical components or components which are similar in structure but have the same function.

In order to make the appearance of the figures concise, only those components which are relevant to the present invention are shown schematically in the various drawings; these do not represent the actual structure thereof as a product. In addition, in order to make the appearance of the figures concise and easy to understand, in some drawings, in the case of components having the same structure or function, only one of these is schematically drawn, or only one is marked.

Fig. 1 is an exploded schematic diagram for explaining the three-dimensional structure of an illustrative embodiment of the wiring assembly for detachable fixing of a detection or alarm device (Fig. 1 only shows one of four wiring assemblies comprising a self-locking connector block 20 and a contact plate 30 in exploded view as part of the mounting base; Fig. 2 shows the mounting base 40 with a bottom case 41 and four of the wiring assemblies shown in Fig. 1) The mounting base is used for detachable fixing of a smoke detector as an example for a detection or alarm device to connect wires 10 of a fire control terminal to a control circuit board (not shown in the figure) of the smoke detector, so as to achieve data connection between the control terminal and the smoke detector.

As shown in Fig. 1, the wiring assembly for detachable fixing of a detection or alarm device comprises a self-locking connector block 20 and a contact plate 30. The self-locking connector block 20 is a commercially available product, and comprises two connecting holes 22 and one connecting end 24. The wires 10 can be clamped in the connecting holes 22 of the connector block 20. The contact plate 30 is provided with a contacting part 32 and a connecting part 34; the contacting part 32 can be electrically connected to the control circuit board of the smoke detector, with the connector block 20 being fixed to the connecting part 34. Electrical connection between the connector block 20 and the contact plate 30 is accomplished by way of electrical connection between the connecting end 24 of the connector block 20 and the connecting part 34 of the contact plate 30, thereby connecting the wires 10 electrically to the control circuit board.

By using a commercially available self-locking connector block, the mounting base for detachable fixing of a detection or alarm device is able to conveniently achieve the fixing of the wire to the connector block, and the detachment thereof, thereby accomplishing a connection between the control circuit board of the smoke detector and the fire control terminal connected to the wires. For example, in the connector block of the self-locking type shown in Fig. 1, each connecting hole 22 is correspondingly provided with an operating hole 26; when a wire 10 is being mounted in the self-locking connector block 30, connection of the wire 10 to the connector block 20 can be achieved by inserting a screwdriver or other tool into the mounting hole 26 and pressing, then inserting the wire 10 into the connecting hole 22 and withdrawing the tool that was inserted into the operating hole 26. When it is necessary to remove the wire 10 from the connecting hole 22 in order to break the connection between the control terminal and the control circuit board, all that need be done is to insert a screwdriver or other tool into the operating hole 26 and press, and the wire 10 can then be detached from the connecting hole 22. The whole process of fixing and detaching the wire is a simple and easy operation, and the space occupied by the wiring assembly is very small; other types of self-locking connector block may also be used as required.

In the schematic embodiment shown in Fig. 1, the connector block 20 comprises two connecting holes 22 and two operating holes 26, each operating hole 26 being capable of independently controlling the clamping and detachment of a wire 10 in the connecting hole 22 corresponding thereto. The connector block 20 of one wiring assembly comprises two connecting holes 22 and is capable of achieving connection with two wires used to transmit the same signal, thus the reliability of connection of the wiring assembly is increased; the number of wires connected to the self-locking connector block can also be varied as required.

As Fig. 1 shows, the connecting end 24 of the connector block 20 is two pins arranged to separately correspond to the connecting hole 22; the embodiment shown in Fig. 1 includes two connecting holes, so four pins are correspondingly provided, but Fig. 1 only shows two pins arranged to separately correspond to different connecting holes 22. Mounting holes 36 corresponding to the pins 24 are provided on the connecting part 34; fixing of the connector block to the contact plate and electrical connection there between is achieved by having the pins 24 penetrate the mounting holes 36, and then fixing the connector block 20 on the connecting part 34 via the pins 24 by welding. Self-locking connector blocks with other fixing methods may also be used as required, for example a surface-mounted self-locking connector block.

Fig. 2 is an exploded schematic diagram for explaining the three-dimensional structure of an illustrative embodiment of the mounting base for detachable fixing of a detection or alarm device. In the structure shown in Fig. 2, the mounting base 40 for detachable fixing of a detection cr alarm device comprises four of the above wiring assemblies. The wiring assembly comprises a connector block 20 and a contact plate 30, the mounting base 40 is provided with a bottom case 41, and the bottom case 41 is provided with accommodating spaces 42 for mounting the wiring assemblies, the accommodating spaces 42 being adapted to the shape of the wiring assemblies. In the structure shown in the figure, the contact plate 30 of the wiring assembly comprises a pair of inserting parts 38 (only one is shown in the figure), and the bottom case 41 is also provided with a pair of slots 48 (only one is shown in the figure); by inserting the inserting parts 38 of the contact plate 30 into the slots 48 of the bottom case 41, the contact plate 30 fitted with the connector block 20 can be firmly fixed in the accommodating space of the bottom case 41, thereby preventing contact with the control circuit board from being affected due to looseness of the contact plate 30 when the smoke detector is in use. Although there are four wiring assemblies mounted in the mounting base for detachable fixing of a detection or alarm device shown in Fig. 2, the number of wiring assemblies used in the mounting base for detachable fixing of a detection or alarm device may be varied as required.

The detection device which can use the mounting base may be in particular a smoke detector, and the alarm device is in particular a sounder, a beacon or a sounder/beacon combination.
