Abstract
The utility model discloses a DC (direct current) jack box which comprises a base installing board, a DC fuse arranged on the base installing board, an input terminal arranged on one end of the DC fuse and used for accessing a cable bus, and a feed output terminal strip arranged at the other end of the DC fuse and used for leading out a cable. The DC jack box disclosed by the utility model can overcome the defects of the traditional DC bus power supply structure, can save space, effectively prevents electromagnetic interference, improves the safety factor, and reduces the potential safety hazard.
Description
Technical field
The utility model relates generally to the electrical power distribution field, is meant a kind of direct current jack box especially.
Background technology
In traditional DC bus powered structure, DC distributor is set and adopt many big line footpath power cables by this DC distributor in terminal is the communication equipment power supply.
The inventor finds when realizing technical solutions of the utility model, at least have following shortcoming in the prior art: by DC distributor being set and adopting many big line footpath power cables by this DC distributor is the scheme of communication equipment power supply, except needs take a large amount of vertical space and horizontal space, the electromagnetic interference that also can exist power cable radiation in parallel to produce, and self temperature raises or reduces many potential safety hazards of being brought.
The utility model content
The utility model proposes a kind of direct current jack box, can solve the existing shortcoming of traditional DC bus powered structure, can save the space, effectively prevent electromagnetic interference, and can improve coefficient of safety, reduce potential safety hazard.
The technical solution of the utility model is achieved in that
A kind of direct current jack box comprises:
The base mounting panel;
Be arranged at the dc fuse on the described base mounting panel;
Be arranged at the input terminal that cable bus inserts that is used for of described dc fuse one end;
Be arranged at the feed lead-out terminal row who is used to pick out cable of the described dc fuse other end.
Preferably, described input terminal is the bus interface, described bus interface be set to the to peg graft interface form of described cable bus.
Preferably, also comprise:
The insulation assembly that is provided with at interval with described bus interface.
Preferably, described direct current jack box also is provided with a shell.
Preferably, also be provided with on the described shell and be used for the wire hole that described cable passed and had waterproof effect.
Preferably, described wire hole is arranged at described feed lead-out terminal and arranges on the described shell of a side.
Preferably, also be provided with one described direct current jack box is locked at anti-drop device on the described cable bus.
Technical solutions of the utility model propose a kind of direct current jack box and replace the technical scheme that DC distributor will be set in terminal in traditional DC bus powered structure, terminal no longer needs to be provided with DC distributor and adopts many big line footpath power cables by this DC distributor is the communication equipment power supply, can save the space, effectively prevent electromagnetic interference, and can improve coefficient of safety, reduce potential safety hazard.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of direct current jack box first embodiment of the utility model.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, show the structural representation of a kind of direct current jack box first embodiment of the utility model, described direct current jack box comprises base mounting panel 7; Be arranged at the dc fuse 2 on the described base mounting panel 7; Be arranged at the input terminal that cable bus inserts that is used for of described dc fuse 2 one ends; Be arranged at the feed lead-out terminal row 5 who is used to pick out cable 8 of described dc fuse 2 other ends.
Described base mounting panel 7 and the dc fuse 2 that is arranged on institute's base mounting panel 7 are the core of described direct current jack box.
Pick out cable 8 and be not directly connected on the described dc fuse 2 and be connected with described feed lead-out terminal row 5 or peg graft by described feed lead-out terminal row 5 being set, making, can reduce power cable 8 torsion, help power cable 8 and export.
Wherein, described input terminal is a bus interface 3, described bus interface 3 be set to the to peg graft interface form of described cable bus, and by the setting of described bus interface 3, described cable bus can be plugged on the described direct current jack box easily.
Preferably, described direct current jack box also comprises:
Insulation assembly 4 with described bus interface 3 interval settings.
Described insulation assembly 4 can be tabular epoxy resin material or other material, and the insulation assembly 4 by being provided with at interval with described bus interface 3 can prevent the short circuit phenomenon between the described bus interface 3, can better improve coefficient of safety.
In addition, described direct current jack box also is provided with a shell 1.
Described shell 1 is positioned at the outside of whole device, is used for each parts of enclosure interior are carried out electromagnetic shielding and mechanical protection.
Also be provided with on the described shell 1 and be used for the wire hole 6 that described cable 8 passed and had waterproof effect.
Described wire hole 6 is preferably disposed on described feed lead-out terminal and arranges on the described shell 1 of 5 one sides, and certain described wire hole 6 can also be arranged at other position on the described shell 1, and the utility model does not limit this.
Described wire hole 6 with waterproof effect can realize by materials such as rubber are set on the aperture that the utility model does not carry out any qualification to this.
By described wire hole 6 with water-proof function is set, when power cable 8 when described wire hole 6 passes described shell 1, liquids such as anti-sealing enter in the described direct current jack box, can strengthen IP (IngressProtection enters protection) degree of protection, improve safety system, and be convenient to the engineering operation.
In addition, described direct current jack box can also be provided with an anti-drop device, described anti-drop device is that described direct current jack box is plugged on the locking device on the direct current cables bus, thereby prevents the slippage from the direct current cables bus of described direct current jack box, and increases and be electrically connected reliability.
One of ordinary skill in the art will appreciate that; the above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle; any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
