Abstract
The utility model provides an output intrinsically safe power supply module, and solves the problem that an output intrinsically safe power supply module is inconveniently to install in the prior art. The power supply module includes a housing assembly, a PCB assembly is packaged in the housing assembly, the lower end of the housing assembly is provided with a first chute and a second chute which cooperate with a guide rail, and two ends of the guide rail are respectively arranged in the first chute and the second chute. According to the output intrinsically safe power supply module, the PCB assembly is packaged in the housing assembly, then the housing assembly is connected with the guide rail and connected with a flame-proof cavity or a cabinet through the guide rail, the housing assembly is just needed to be locked on the guide rail when the output intrinsically safe power supply module is installed, and installation is comparatively convenient.
Description
Technical field
The utility model relates to a kind of supply unit, the safety electric source module that particularly a kind of explosion-proof occasion is used.
Background technology
The core component that output intrinsically safe power supply module is output intrinsically safe power supply, common mounting means has two kinds.The first is that floor type is installed, as shown in Figure 1, the circuit part of power supply (PCB assembly) is positioned in plastic casing 10 and rubber seal, underlying base plate 11, base plate is installed in flame proof cavity or in rack by fixing hole again, and its shortcoming is on-the-spot mounting casing assembly and changes the extremely inconvenience of PCB assembly.The second mounting means is that PCB assembly is directly installed, and the PCB assembly that is about to export intrinsically safe power supply is directly installed in flame proof cavity or in rack, its wiring and change more inconvenient.
Utility model content
The utility model proposes a kind of output intrinsically safe power supply module, the output intrinsically safe power supply module that has solved prior art is installed inconvenient problem.
The technical solution of the utility model is achieved in that a kind of output intrinsically safe power supply module, comprises casing assembly, is packaged with PCB assembly in casing assembly, and described casing assembly lower end is provided with the first chute and the second chute coordinating with guide rail.
Described PCB assembly is pegged graft and is connected with binding post.
Described casing assembly side is provided with side label.
The utility model in casing assembly, is connected by casing assembly PCB component package afterwards with guide rail, by guide rail, be connected with flame proof cavity or rack, when installing, only casing assembly need to be stuck on guide rail, installs more convenient.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the schematic top plan view of Fig. 2;
Fig. 4 is the structural representation of casing assembly;
Fig. 5 is the structural representation of guide rail;
Fig. 6 is the schematic top plan view of Fig. 5.
Wherein, 1. casing assembly, 2. side label, 3. top mark board, 4.PCB assembly, 5. the first chute, 6. the second chute, 7. guide rail, 8. fixing hole, 9. binding post.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model comprises casing assembly 1, is packaged with PCB assembly 4 in casing assembly 1, and described casing assembly 1 lower end is provided with the first chute 5 and the second chute 6 coordinating with guide rail 7.
Described fixing hole 8 is bar holes, and this setup can be adjusted the installation site of guide rail so that guide rail is more convenient fixedly time, guide rail is coordinated more convenient with installing hole on flame proof cavity or pre-embedded bolt.
Described PCB assembly 4 is pegged graft and is connected with binding post 9.Adopt binding post wiring, only need the binding post on plug both sides in the time of replacing, from guide rail, take off original casing assembly and PCB assembly, the binding post that change New Parent, inserts again afterwards two ends completes replacing.
Described casing assembly 1 side is provided with side label 2, and described casing assembly 1 top is provided with top mark board 3.On side label 2 and top mark board 3, can indicate product related information.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
Claims (4)
1. export intrinsically safe power supply module for one kind, comprise casing assembly (1), in casing assembly (1), be packaged with PCB assembly (4), it is characterized in that: described casing assembly (1) lower end is provided with the first chute (5) and the second chute (6) coordinating with guide rail (7).
