Description
Technical field
The present invention relates to electrical equipment technical field, be specifically related to a kind of straight-line multichannel safety box.
Background technology
Fuse electrical appliance kit, as a kind of electrical equipment, can be used on the automated machine such as motor vehicle, steamer equipment conventionally. The version of safety box, mainly can be divided into plug-in type safety box, busbar formula safety box, wiring type safety box, printed substrate safety box and the integrated safety box of electronics. Wherein, comparatively conventional printed substrate safety box is pcb board formula safety box at present, and the wiring board using is mostly one deck double-sided copper-clad circuit board, back side outlet method, and connector is arranged in the box body back side. But along with increasing of electric equipment function, the wire harness docking with safety box must increase, adopt back side outlet method, will cause safety box overall volume larger, be unfavorable for the installation in electric equipment. And in the time checking plug connector, safety box need to be disassembled, be not easy to searching and keeping in repair of trouble point.
In existing pcb board formula safety box, the distribution mode of power supply generally: adopt power supply access post (as copper post) at right angle setting on pcb board,, be from the close-by examples to those far off electrically connected by printed wire successively with each guard terminal enough as starting point taking the post of power supply access post. The power supply access way of this vertical PCB circuit board, being connected apart from not etc. of the post foot of power supply access post and each guard terminal on pcb board, under identical voltage input, the sufficient nearer guard terminal resistance of distance post is less, the sufficient guard terminal resistance far away of distance post is larger, so just exists the CURRENT DISTRIBUTION of every road guard terminal of flowing through unbalanced. In order to solve power supply access post and far-end insurance because of apart from the weak problem of the electric current producing too far away, normally adopt between power supply access post post foot and far-end insurance and lay Xi Dao, in Huo Xi road, bury the method for copper cash underground. But lay tin procedure more complicated, cost is higher, and the thickness length of Xi Dao is difficult to even setting, its reliability is low, still have great potential safety hazard. Along with the function of electric equipment is on the increase, make the distribution of power supply in safety box become more complicated, needed fuse, relay quantity are doubled and redoubled. And the integrated insurance way of the safety box of current PCB circuit board type is generally 30 left and right, tunnel, needs are accessed to the more safety box of multichannel insurance, the power supply access way of existing PCB circuit board cannot meet.

In above embodiment, related instrument and equipment if no special instructions, is routine instrument device.
Taking the straight-line multichannel safety box in embodiment 2 as example, its specific works mode is as follows:
The input copper bar of enough current-carrying capacities is arranged at the back side of upper plate abreast, by conducting bolt, input copper bar 11 and upper plate 1 is tightened together, and makes to input copper bar 11 and forms reliable electrical connection with the contact portion of upper plate 1. Conducting bolt is simultaneously also by the front of conduct current upper plate, by this mode, the two row's insurance slots 14 that make to be positioned at upper plate 1 front, be arranged with input copper bar 11 in parallel form and are equidistantly connected with input copper bar 11, ensure the CURRENT DISTRIBUTION equilibrium of input copper bar 11 to each insurance slot, the uneven risk producing of CURRENT DISTRIBUTION of having avoided existing copper column type power supply access way to produce.
The setting of large current insurance device, makes can carry in safety box of the present invention the electric current of 30A～80A, has realized the insurance protection to larger electric current. Generally, large current insurance refers to insurance more than 30A, and its more difficult being integrated in safety box, because its single channel is larger through overcurrent, adopts plug-in type insurance to bring larger contact resistance, has the risk that burns out pcb board and socket. Large current insurance device in the present invention adopts ad hoc copper bar 61 is set, be arranged at the front of upper plate 1, form right-angled intersection with one of them input copper bar, offer bolt access hole in this right-angled intersection position of upper plate, in bolt access hole, cylindrical copper band 65 is set, the thickness of copper band 65 is greater than the thickness of upper plate 1, and fastening bolt 62, successively through the input copper bar 11 of bottom, the copper band 65 of centre and the ad hoc copper bar 61 on top, is tightened together and forms electrical connection. Such connected mode, makes electric current directly flow to ad hoc copper bar 61 from input copper bar 11, process copper band 65, and larger electric current does not need the upper plate 1 through PCB circuit board, the risk that this has just been avoided the process of large electric current that pcb board is burnt out. Meanwhile, large current insurance device adopts insurance to draw bolt 63 through upper plate 1 and ad hoc copper bar 61, forms bolt fixed insurance incoming end, but not adopt splicing type insurance on ad hoc copper bar 61, has further avoided large electric current to burn out the potential safety hazard of components and parts.
In use, the insurance socket 41 of the fuse holder cartoon of splicing type being crossed on box body panel 4 is inserted in the insurance slot 14 in upper plate 1 front; The bolt fixed that is installed on of board-like insurance 64 correspondences is insured to incoming end; Wire bundle plug-in connector is passed through to the wiring harness interface 42 of box body panel 4 and the corresponding connection of wire harness incoming end 15 in upper plate 1 front; The corresponding connection of power access end 12 by power line with input copper bar; Ensure that each junction forms reliable electrical connection. Because the input/output terminal of safety box of the present invention is in the same side (upper plate front) of PCB circuit board, compare traditional output and be positioned at the mode at the pcb board back side, more convenient when installation wiring. In the time of certain device fails, corresponding insurance fuses, and the fusing indicator lamp at this place is lit, and user can diagnose rapidly accordingly the position of the generation of being out of order and overhaul. The safety device 7 of installing at power access end 12 places of input copper bar, can play insulation and dustproof effect, has avoided the power access end of input copper bar because of the exposed electric leakage causing, short circuit problem, has increased the security of safety box.
In conjunction with the accompanying drawings and embodiments the present invention is described in detail above, but, person of ordinary skill in the field can understand, do not departing under the prerequisite of aim of the present invention, can also change each design parameter in above-described embodiment, form multiple specific embodiments, be common excursion of the present invention, describe in detail no longer one by one at this.
