Abstract
The utility model relates to a branch connection box. The branch connection box comprises a box body and a base, wherein electrical components are accommodated in the box body, and a side wall of the base is provided with convection holes. When the electrical components work, heat will be generated, so the temperature of the air in the box body is quite high. Because the side wall of the base is provided with the convection holes, the air in the box body will flow towards the base, thus, air convection is produced, moisture in the vicinity of the base can be taken away, thereby avoiding the generation of condensation. In addition, the temperature of the air in the box body is quite high, the temperature of the base can be increased, thereby further avoiding the generation of condensation. As a result, an extra heating device is not required to be added in the branch connection box, which enables structural simplicity; and further, the air of which the temperature is quite high in the box body can be taken away, the temperature inside an accommodating cavity can be maintained in a lower-temperature range, and therefore, the generation of condensation can be avoided, and the normal operation of the electrical components can be facilitated at the same time.
Description
Technical field
The utility model relates to distribution technique, particularly relates to a kind of distribution box.
Background technology
Distribution box generally is installed on the outdoor cable trough.Because outdoor environment is changeable, cable trough may ponding, thereby cause the base of distribution box to be in the wet environment always.When the base inner wall drop in temperature was following to dew point temperature, airborne moisture just can condense at base inner wall, produced condensation.Thereby may affect the normal operation of electric component in the distribution box.
Generally take at present mode of heating to avoid producing condensation.But heating needs extra mounting heater.Need on the one hand to consume electric energy; May cause on the other hand the ambient temperature of electric component too high.And, because the mode of heating is not also for discharging moisture.Therefore, in case stopped heating, steam again can regelation.
The utility model content
Based on this, be necessary to provide a kind of simple in structure, do not need in addition heating but can effectively avoid producing the distribution box of condensation.
A kind of distribution box comprises:
Casing has host cavity, has taken in electric component in the described host cavity, and described electric component work can produce heat; And
Base is fixedly connected with described casing, and by heating panel and the isolation of described host cavity, offers convection holes on the sidewall of described base.
Among embodiment, the quantity of described convection holes is a plurality of, and is distributed on the sidewall of described base therein.
Among embodiment, also comprise protection network therein, described protection network is installed on the sidewall of described base, and covers described convection holes.
Among embodiment, described protection network is the porous flake plate structure therein.
Among embodiment, also comprise air conduction equipment therein, described air conduction equipment holding is in described base, and the bootable air of described air conduction equipment produces convection current.
Above-mentioned distribution box comprises casing and base.Casing has host cavity, contains electric component in it.Base is fixedly connected with casing, and by heating panel and host cavity isolation.Owing to also offering convection holes on the sidewall of base.Therefore, the air in the base can produce cross-ventilation, thereby the moisture in the base is taken out of, and then can avoid producing condensation.In addition, can produce heat during electric component work, therefore the temperature of air is higher in the casing.And the heat that produces can be dispersed into base by heating panel, thereby increases the temperature of base.The base temperature raises, and then water more easily becomes steam, thereby more easily takes away when cross-ventilation, therefore, can further avoid condensation to generate.Therefore, above-mentioned distribution box need not additionally increase heater just can reach the effect that prevents condensation, simple in structure.
In addition, because the waste heat in the casing is dispersed into base by heating panel, the temperature in the host cavity is maintained in the lower scope, thereby when avoiding producing condensation, can also guarantee the normal operation of electric component.
Description of drawings
Fig. 1 is the structural representation of distribution box among the embodiment;
Fig. 2 is the enlarged diagram of the local A of distribution box shown in Figure 1.
Embodiment
For the ease of understanding the utility model, the below is described more fully the utility model with reference to relevant drawings.Provided preferred embodiment of the present utility model in the accompanying drawing.But the utility model can be realized with many different forms, be not limited to embodiment described herein.On the contrary, provide the purpose of these embodiment be make the understanding of disclosure of the present utility model more comprehensively thorough.
Need to prove, when element is called as " being fixed in " another element, can directly can there be element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be to be directly connected to another element or may to have simultaneously centering elements.
Unless otherwise defined, the employed all technology of this paper are identical with the implication that belongs to the common understanding of those skilled in the art of the present utility model with scientific terminology.Employed term is not intended to be restriction the utility model just in order to describe the purpose of specific embodiment in specification of the present utility model herein.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
As shown in Figure 1, the distribution box 100 of the utility model better embodiment comprises casing 110, base 120, protection network 130 and air conduction equipment (not shown).
As shown in Figure 2, protection network 130 is installed on the sidewall of base 120 and covers on the convection holes 121.Protection network 130 is the porous flake plate structure.Protection network 130 can prevent that foreign material from entering in the distribution box 100, for the protection of the electric component in the distribution box 100.It is pointed out that in other embodiments, protection network 130 can omit.
The air conduction equipment holding is in base 120.The bootable air of air conduction equipment produces convection current.Air conduction equipment can be air blast, ventilating fan etc.Because speed air flow is slower in the natural situation.Therefore, at natural situation lower bottom base 120 inner air convection DeGrains.Air conduction equipment can be accelerated by external force the flow velocity of air, strengthens convection effects.It is pointed out that in other embodiments, air conduction equipment can omit.
In addition, because the waste heat in the casing 110 is dispersed into base 120 by heating panel, the temperature in the host cavity is maintained in the lower scope, thereby when avoiding producing condensation, can also guarantee the normal operation of electric component.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
