Abstract
The utility model discloses a circuit board of an automotive electric appliance concentration distribution box. The circuit board comprises a printed circuit board and a standard socket arranged on the printed circuit board. The printed circuit board comprises an upper printed circuit board and a lower printed circuit board. Holes which are matched with an automobile standard fuse socket or a relay socket are distributed on the upper printed circuit board. The upper printed circuit board is provided with the hole which is matched with conductive columns. The automobile standard fuse socket or the relay socket and the each conductive column are inserted into an automobile standard fuse socket hole with a pad or a relay socket hole and a conductive column socket hole corresponding to the upper printed circuit board respectively. The automobile standard fuse socket or the relay socket and the each conductive column are exposed on an upper side and a lower side of the upper printed circuit board respectively. A pin of an exposed portion of the each conductive column is inserted into the hole with the pad on the lower printed circuit board. A bus bar is arranged on the lower printed circuit board between the adjacent conductive columns. The lower printed circuit board is also provided with the hole which is matched with an automotive onboard connector. The circuit board of the utility model is used for the automotive central electric appliance distribution box.
Description
Technical field:
The utility model relates to a kind of wiring board of vehicular electrical appliance centralized power distribution box.
Background technology:
The internal electric structure of the automobile-used central electrical equipment block terminal of producing roughly has two kinds now: copper bar structure and printed circuit plate structure.
The central electrical equipment block terminal of copper bar structure is with mould copper coin to be made the copper bar that length, width, thickness and shape adhere to specification, it is linked to each other with central electrical equipment block terminal connector (terminal), fuse, relay, with insulant insulation and fixing, be fixed on again up and down on the plastic cover plate between the copper bar.Because copper bar good conductivity, cross-sectional area are bigger, there is insulant to fix again, so caloric value is not very big, generally can not cause short circuit because of the heating distortion, so relative reliability is better.But general central electrical equipment block terminal is done copper bar and is wanted tens pairs of moulds, and full copper wire is big with the copper material amount, and the copper material price is also very high, so manufacturing cost is very high, is difficult for revising, and volume is also bigger.
The central electrical equipment block terminal of printed wiring board structure is to use double side printed wiring board, realize that by the pad of printing customization copper foil circuit and line end on the wiring board fuse, relay, connector (terminal) are associated, and are fixed in plastic casing inside then.Board structure of circuit is small and exquisite, electrical arrangement does not need to customize particular manufacturing craft flexibly, and printed wiring board is cheap, so cost is lower.But, because central all circuits of electrical equipment block terminal all concentrate on the printed wiring board, line density is bigger, copper thickness is limited by production technology, so the caloric value of circuit board by big electric current the time is bigger, current capacity when fault (especially short circuit current) is not good, so reliability is relatively poor relatively.
Summary of the invention:
The purpose of this utility model provides the wiring board of a kind of vehicular electrical appliance centralized power distribution box that a kind of caloric value is little, the ability of damming is big and cost is low.
The technical scheme that realizes the utility model purpose is, a kind of wiring board of vehicular electrical appliance centralized power distribution box, comprise printed substrate and on standard socket, it is characterized in that: described printed substrate is last, following two printed substrates, described going up on the printed substrate is distributed with the hole that matches with car gage fuse receptacle or relay socket, on printed substrate on above-mentioned car gage fuse receptacle or relay socket hole one side, be provided with the hole that matches with conductive pole, above-mentioned car gage fuse receptacle or relay socket and conductive pole are inserted in respectively in printed substrate on this corresponding the car gage fuse receptacle hole that has pad or relay socket hole and conductive pole socket aperture, above-mentioned car gage fuse receptacle or relay socket and conductive pole expose to upside and the downside of printed substrate respectively, described down printed substrate is provided with the hole that has pad that the pin with described conductive pole exposed parts matches, and it is relative with conductive pole hole on the last printed substrate, following printed substrate between the adjacent conductive post is provided with bus, the bending leg at these bus two ends is through at down in the hole of printed substrate tape welding dish, also be provided with Automobile Plate on following printed substrate and carry the hole that has pad that connector matches, the hole on this pad and above-mentioned Automobile Plate are carried connector and are matched.The material of described conductive pole and bus is copper material.The specification of described bus is two kinds.
The utility model has the remarkable advantage that the ability of damming is big, caloric value is little and cost is low compared with the prior art.
Description of drawings:
Fig. 1 is the vertical view of the utility model wiring board; Fig. 2 is the A-A profile of Fig. 1; Fig. 3 is the B-B cutaway view of Fig. 2; Fig. 4 is the other wiring form schematic diagram of printed substrate bus under the utility model wiring board.
Embodiment:
Not have under big current load caloric value little in order to solve existing printed panel, and the low defective of technology cost, the utility model adopts following technical scheme, printed substrate of the present utility model has two, car gage fuse or relay socket 2 usefulness wave-soldering technologies are welded on the printed substrate 1, the conductive pole 3 that can rivet is riveted on this on printed substrate, above-mentioned socket and conductive pole expose to upper surface and the lower surface of printed substrate respectively, the upper surface of the following printed substrate between conductive pole is provided with the bus 6 of square distribution, under inserting, the bending leg at these bus two ends in the pad hole at printed wire plate hole and two ends, hole, makes conductive pole by wave-soldering, the bus pin is connected mutually with following printed substrate 5.Also be provided with the hole 4 that matches with automobile mounted connector on the following printing path plate, the two-port in hole respectively is provided with pad.The material of above-mentioned conductive pole and bus preferably adopts the material of good conductivity, as copper material, the length of above-mentioned bus is determined according to the specification size of electric elements, the length specification of bus can have two kinds or three kinds all can, but specification is more many, the mould of punching out bus will be many, cause cost to increase, from this point of view, adopt equal length bus cost low, mold management is also easy.
The utility model is owing to adopted the two-layer printed circuit plate, standard fuse, relay socket or non-standard socket arrangements are on last printed substrate, the circuit of above-mentioned components and parts is arranged in down on the printed substrate, for circuit arranges that particularly the layout of complicated circuit provides the space, and big bus and the conductive pole of employing conductive capability, the loaded current ability is big, and caloric value is less, has solved the defective that existing printed substrate exists.
