Specific embodiment
Embodiment one is a kind of module power source casing disclosed by the utility model, outside the modular power source referring to Figures 1 and 2
The cavity of a shell generally hollow, rectangular is mainly made of upper housing 1, bottom plate 2 and two the first side plates 21 being oppositely arranged.
Upper housing 1 has a upper plate 11 and two the second side plates 12.Two the second side plates 12 are oppositely arranged, and the second side plate 12 is by upper plate
11 long side, which extends vertically, to be formed, and is formed on the inner plate surface at respective both ends and two in two the second side plates 12
The mutually matched connected structure in structure, on position, bottom plate 2 are fixedly connected with upper plate 11 by screw side plate 21 each other.
Pass through 11, two the first side plates 21 of a upper plate and two the first side plates 21 mating two the second side plates 12 and bottom plate
2 together form the cavity of hollow, rectangular.The inside cavity is for installing pcb board and relative electronic components, two second side
Screw hole is offered on the end face of plate 12 and on 2 corresponding position of bottom plate for mounting base 2.
With reference to Fig. 3, wherein connected structure includes the twice first opened up on the inner plate surface that the second side plate 12 leans on two close end
Two the first tongues 5 of slot 4 and two inserted terminals formation in the first side plate 21.More specifically, on two the second side plates 12
The first slot 4 be oppositely arranged, one end of the first slot 4 penetrates through out the second side plate 12, and the other end is along perpendicular to 11 institute of upper plate
On the inner plate surface that the direction of plane extends to upper plate 11；First tongue 5 is the shape that extends outwardly in the middle part of the end face by inserted terminal
At, the equal length of the length of the first tongue 5 and the first slot 4 is inserted so that the first tongue 5 is from top to bottom inserted into first
After in slot 4, the upper surface of the first tongue 5 is flushed with the upper surface of the second side plate 12.
With reference to Fig. 2, in order to make pcb board and the electronic component of inside cavity sufficiently radiate, the surface of upper plate 11 is along upper
The longitudinal direction of plate 11 offers the groove of perforation, forms the first radiating groove 6, short side direction of first radiating groove 6 along upper plate 11
If equidistantly offering arterial highway；Likewise, the surface of two the second side plates 12 is equidistantly opened along the short side direction of the second side plate 12
If forming the second radiating groove 61 equipped with arterial highway groove, the groove through direction of the second radiating groove 61 and the first radiating groove 6 are kept
Unanimously.On the one hand the pcb board of inside cavity and electronic component heat pass through subtracting for the first radiating groove 6 and the second radiating groove 61
Thickness setting can rapid cooling, while cooperating outer fan blowing that can be formed in the first radiating groove 6 and the second radiating groove 61
Heat is quickly taken away in air duct.
Further, the surface of the second side plate 12 offers at least two avoid holes 7 along the long side direction, sets in the present embodiment
There are three setting, quantity is determined according to outer casing of power supply specification and external mounting condition.More specifically, avoid holes 7 are semicircle orifice,
Each avoid holes 7 penetrate through setting along the short side direction of the second side plate 12.Such setting is capable of increasing 12 surface of the second side plate
Heat dissipation area accelerates the conduction of heat and scatters and disappears；Avoid holes 7 can also be fixed on electrical cabinet by screw simultaneously.
It with specific reference to Fig. 1, is opened up in the plate face of upper plate 11 there are four mounting hole 8, is mainly used for that pcb board is fixedly mounted, makees
For a kind of preferred embodiment, the position of mounting hole 8 is respectively positioned in the groove of the first radiating groove 6 formation, the power supply after encapsulating in this way
Module, internal heat can be conducted by screw to the first radiating groove 6, and quickly take away heat by blowing.
Further, upper plate 11 offers insert row entrance 9 far from the other side of mounting hole 8, which is by ipsilateral
Upper plate 11 and the first side plate 21 rectangular aperture for cutting jointly collectively form.Cable is offered on two the first side plates 21
Mouth is for exporting cable.
The assembling process of the module power source casing is described below and understands the design of its structure with more convenient: first by upper housing 1
It is inverted, pcb board is installed, pcb board is fixed on inside cavity by penetrating the bolt of mounting hole 8；Then by two the first side plates 21
It is inserted by tongue in the first slot 4 of two the second side plates 12, it is ensured that the upper surface of the first side plate 21 and the second side plate 12
Upper surface flushes；Finally, covering bottom plate 2, bottom plate 2 is fastened to close pcb board by screw, is just completed outside modular power source
The assembling of shell, the module power source casing repair demolition Shi Yuqi assembling process are opposite.Compared to the design of the more screw of tradition, originally
The module power source casing of embodiment assembles light, assembly time faster.
Embodiment two refers to Fig. 4 and Fig. 5, with embodiment one the difference is that the difference of connected structure, the connected structure
Including two the second tongues 101 being arranged on inner plate surface of second side plate 12 close to its both ends and in two of the first side plate 21
The second slot of twice 10 that inserted terminal is formed.More specifically, the second tongue 101 on two the second side plates 12 is oppositely arranged, the
Two tongues, 101 one end extends to the upper end surface of the second side plate 12, and the other end is along the side perpendicular to plane where 11 face of upper plate
To extending on the inner plate surface of upper plate 11；Second slot 10 is to be recessed inwardly to be formed in the middle part of the end face by inserted terminal, and second inserts
The equal length of the length of slot 10 and the second tongue 101, so that the second slot 10 is from top to bottom completed with the second tongue 101
After grafting, the end face of the upper surface of the second tongue 101 and the second side plate 12.
Embodiment three refers to Fig. 6 and Fig. 7, and from embodiment one the difference is that the structure of the first tongue 5 is different, this first
Tongue 5 is to extend outwardly to construct close to the end face of cavity side by the inserted terminal of the first side plate 21 to be formed, the first tongue 5 with insert
The end face for connecing end is formed as L shape.Compared to embodiment one, present embodiment reduces the thickness of the first side plate 21.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
