Abstract

The utility model discloses a kind of pcb board and lower cover improved connection structure, comprise pcb board, lower cover and one group of shell fragment, described one group of shell fragment respectively by a fixing hardware be fixed on described under cover, described lower cover side is provided with one group of lower cover rib, keep at a certain distance away between described one group of lower cover rib and described shell fragment, described pcb board inserts in the gap formed between lower cover rib and shell fragment; Pcb board is connected with lower cover by shell fragment mode, and without the need to wire bonds, operation is few, simple to operate, and production cost is low, there is not potential safety hazard, and structure is more compact, and performance is more stable.

Description

Pcb board and lower cover improved connection structure

Technical field

The utility model belongs to power supply adaptor field, particularly the modified node method that is connected with lower cover of a kind of pcb board.

Background technology

In power supply adaptor, pcb board just will can complete charging with the plug electrical communication of lower cover side, is specially, wire one end is welded on pcb board, and the wire other end is welded on the through wires hole in lower cover hardware, and this mode can realize electrical communication between the two, but also there is very large defect, operation is many, and manpower and materials have high input, and soldering connects to be needed to use a large amount of tin metal, production cost is high, and wire arranges trouble, easily occur that broken skin damages phenomenon, have certain potential safety hazard.

It is simple that the technical problems to be solved in the utility model is to provide a kind of operation, easy and simple to handle, production cost is low, without the improvement syndeton of potential safety hazard.

Utility model content

In order to solve, above-mentioned prior art operation is many, production cost is high, there is the problems such as potential safety hazard, and the utility model adopts following technical scheme:

The utility model provides a kind of pcb board and lower cover improved connection structure, comprise pcb board, lower cover and one group of shell fragment, described one group of shell fragment respectively by a fixing hardware be fixed on described under cover, described lower cover side is provided with one group of lower cover rib, keep at a certain distance away between described one group of lower cover rib and described shell fragment, described pcb board inserts in the gap formed between lower cover rib and shell fragment.

The beneficial effects of the utility model are: pcb board is connected with lower cover by shell fragment mode, and without the need to wire bonds, operation is few, simple to operate, and production cost is low, there is not potential safety hazard, and structure is more compact, and performance is more stable.

Accompanying drawing explanation

Fig. 1 is the decomposition texture schematic diagram that in the utility model, pcb board is not put into.

Fig. 2 is the overall structure schematic diagram after the utility model assembling.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.

Refer to Fig. 1 and Fig. 2, a kind of pcb board and lower cover improved connection structure, comprise pcb board 1, lower cover 2 and comprise one group of shell fragment 3, described one group of shell fragment 3 is fixed on described lower cover 2 respectively by a fixing hardware 21, described lower cover 2 side is provided with one group of lower cover rib 22, keep at a certain distance away between described one group of lower cover rib 22 and described shell fragment 3, described pcb board 1 inserts in the gap formed between lower cover rib 22 and shell fragment 3, during operation, fix hardware 21 by punch holder to wash open, such guarantee shell fragment 3 can not loosen and drop out, pcb board is linked together by the form of shell fragment and lower cover, production operation is more simple, operation is few, effectively reduce cost of labor, product structure is compacter, properties of product are more reliable and stable, and traditional pcb board is connected with lower cover and is realized by wire bonds, by scolding tin, wire two ends are welded together with pcb board and lower cover respectively, when this mode operates, operation is many, manpower and materials have high input, cost of labor is high, also need the scolding tin of at substantial, further add production cost, wire arranges loaded down with trivial details, wire easily occurs when using that broken skin damages phenomenon, there is certain potential safety hazard, this is very disadvantageous to user, but can be addressed this problem by above-mentioned improvement.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.

Claims (1)

1. a pcb board and lower cover improved connection structure, comprise pcb board (1) and lower cover (2), it is characterized in that: also comprise one group of shell fragment (3), described one group of shell fragment (3) is fixed on described lower cover (2) respectively by a fixing hardware (21), described lower cover (2) side is provided with one group of lower cover rib (22), keep at a certain distance away between described one group of lower cover rib (22) and described shell fragment (3), described pcb board (1) inserts in the gap formed between lower cover rib (22) and shell fragment (3).
