By adopting the conductive nails and the conductive springs as conductive elements, the waterproof sealing structure for electrical equipment has the advantages of being waterproof, good in conductive performance, low in cost and durable.
Description
Technical field
The utility model relates to applications of electronic circuitry field, relates in particular to the hermetically-sealed construction that requires conduction.
Background technology
For environmental protection and use cost, consider, rechargeable battery is generalizable in recent years.In the electric energy deficiency of rechargeable battery, will charge to rechargeable battery, current most charging circuit still adopts contact charging, by the mode electrically contacting, allows charger and rechargeable battery form loop, thereby charges the battery.Now also have contactless wireless charging, the mode by electromagnetic coupled charges the battery, and charging circuit and battery circuit directly do not electrically contact.Although convenient, cost is also higher.In low-end applications, be subject to some restrictions.
If need to adopt on the product of waterproof rechargeable battery at some, must waterproof between its charging contact and housing, contact must be also the material that can not get rusty, otherwise must design in addition anti-hydrospace to contact with protection.Can increase product size and cost like this.
In addition, in other situation, also can require the circuit in housing to guide to outside housing, as transmission for signal etc.
PCB is rigidity, if charging contact is also to be made by rigid material, two parts are abutted against while touching conduction just must have extra elastic part to guarantee its good contact.Such as pushing down PCB etc. with elastomeric material.Otherwise it is upper contact part will to be soldered to directly or indirectly to PCB, can increase cost like this, also to later stage assembling, make troubles.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, and a kind of charging contact waterproof sealing structure abundant with pcb board, that effectively contact that guarantees is provided.
To achieve these goals, the utility model has adopted following technical scheme: a kind of waterproof sealing structure of power consumption equipment, it is characterized in that: the waterproof sealing structure of described power consumption equipment comprises seal casinghousing, power circuit system, conductive nail and power spring, on described seal casinghousing, offer the inside and outside through hole connecting, power circuit system is installed on seal casinghousing inner chamber, conductive nail extends to seal casinghousing through described through hole from seal casinghousing inner chamber, between conductive nail and described through hole, form and be tightly connected, power spring one end is pressed in power circuit system and forms with it electrical connection, the other end is connected in conductive nail.
Described seal casinghousing is provided with in conductive nail periphery the bone that encloses that a circle protrudes from seal casinghousing surface.
The side that described conductive nail is positioned at seal casinghousing inner chamber is provided with the shaft shoulder structure that prevents that footpath, the end that conductive nail outwards comes off from expanding.
Described seal casinghousing is assembled by upper shell and lower house, and the described inside and outside through hole connecting is opened in lower house bottom surface.
Described power spring close-fitting is socketed on described conductive nail, to guarantee effective electrical connection the between power spring and conductive nail.
Described conductive nail forms close-fitting with described through hole and is connected, to meet waterproof, seal request.
Further, between described conductive nail and described through hole hole wall and conductive nail and described through hole periphery be filled with binding agent, to guarantee waterproof, seal request.
Described conductive nail adopts stainless steel, or copper, or steel nickel plating or chromium material, not only can meet waterproof, electric conductivity but also have the advantage of cheap and durability concurrently.
The utility model adopts conductive nail and power spring as conducting element, conductive nail is through the through hole on seal casinghousing close-fitting with it, can reach the object of waterproof, the medial extremity of conductive nail and power spring close-fitting, power spring is pressed on PCB or other parts to keep good contact again, the outboard end that conductive nail stretches out housing is connected with outside charging device, makes external charging equipment and internal circuitry conducting.Wherein, conductive nail adopts stainless steel, or copper, or the material such as steel nickel plating or chromium, not only can meet waterproof, electric conductivity but also have the advantage of cheap and durability concurrently.The utility model is simple in structure, easy to assembly, and integrated cost is low.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is that the A of Fig. 1 is to schematic diagram.
Below in conjunction with accompanying drawing, describe:
Embodiment
As shown in Figure 1, be the chargeable structure division of power consumption equipment, it comprises seal casinghousing 1, power circuit system 2, power spring 3, conductive nail 4.
Seal casinghousing 1 is assembled by upper shell 11 and lower house 12, and its inside has the inner chamber that can hold power circuit system 2.Power circuit system 2 comprises again PCB, circuit element, IC, rechargeable battery, load (as motor, coil, LED etc.).Lower house 12 bottom surfaces offer through hole 120.Beyond conductive nail 4 extends to seal casinghousing by through hole 120 from seal casinghousing inner chamber, wherein conductive nail 4 and through hole 120 interference fit, reach water-tight or prevent the object of other dielectric leakages.One end that conductive nail 4 is positioned at seal casinghousing inner chamber is connected with power spring 3, and it is upper that power spring 3 is pressed in the PCB of power circuit system 2 again, in the corresponding positions of PCB, is equipped with conductive foil.The other end via through holes of conductive nail 4 stretches out outside seal casinghousing.For preventing that conductive nail from deviating from from inside to outside, at the medial extremity of conductive nail, be also designed with the shaft shoulder structure 41 of a hole enlargement.The bottom surface of lower house 12 be provided with a corral around each conductive nail enclose bone 121, in order to protect conductive nail to protrude from the part of lower house bottom surface.
When having external equipment to be connected with conductive nail, the conducting of whole power circuit system, can be used for to inner battery charging, or generation signal triggers inner circuit.
Conductive nail can adopt stainless steel, can be also copper, or ordinary steel nickel plating or chromium, has waterproof and electric conductivity, especially has advantage with low cost, durable.
In the present embodiment, conductive nail and through hole can pass through close-fitting waterproof, can be also increase waterproof reliability further, and between conductive nail and housing through-hole, and the periphery of through hole is filled with adhesive.
