Description

The waterproof case of circuit arrangement

The utility model relates to a kind of housing, the waterproof case of the circuit arrangement of particularly a kind of waterproof, protection against the tide and leakproof.

Electric circuit device is widely used in various utensils; the control of equipment; sensing; the power source conversion supply; in communication or the like occasion; for example: traditional light fixture or lamp series controller; electronics or electric wirings such as optical controller; then provided power source conversion; the function of control and sensing control; yet; the electronic building brick that in these electronics or electric wiring, has comprised many precisions; electric component; as transformer; integrated circuit (IC) among the circuit board PCB; rectifier; transistor; optical sensing subassembly or the like electronics or electric component; be used to make circuit arrangement can produce above-mentioned power source conversion; control of lamp string or lamp string; the automatic point of the light fixture controlled function of going out is so these significant components of appropriate protection are necessary.Yet; traditionally; to electronics; the protected mode of electric circuit device; except at voltage; outside the circuit breaker protection of electric current; usually can be coated as transformer with insulation crust; important electron such as circuit board PCB or optical sensing subassembly; electric component; make its influence that is not subjected to external environment and direct destruction; but because the use occasion of this electric circuit device need because of the installation of control appliance; might not be arrest be limited to indoor in or use in the dry environment; as large-scale Christmans light string or lamp sea; the lamp tree is must be by device out of doors; therefore; as lamp series controller or daytime; automatically put the electric circuit devices such as optical controller of the control of going out night, then must cooperate lamp string or lamp device in the open air.But the combination between the coating housing of its outside is normally taked as directly adding hot link, the sealed or mode that fastens with high frequency (ultrasonic wave), so bigger seepage slit appears in the junction between its housing and housing, and be easy to cause after long-time the use its inner precise electronic, electric parts thereby the damage of damp that the makes moist problem bad or that cause line short to damage because of infiltration that makes.

In addition; the waterproof practice that also has a kind of widely used circuit arrangement external shell; be directly some above the important part PUR coat or directly whole body filled with epoxy resin; and whole electric circuit device is packaged in the housing by full solidification; be a kind of more passive waterproof, the moistureproof practice; just allow enclosure interior infiltration or make moist, but important electron, electric component are protected because of the insulative water-proof function of PUR or epoxy resin.And the waterproof construction of in housing, annotate PUR or epoxy resin, be in the manufacture process of actual electric circuit device generation to be expended man-hour, the problem of manpower and shortcoming, the cost of product is improved, and, entire product weight is sharply increased, cause product to become heavy and be unfavorable for installing and using out of doors; And, in the course of processing, the temperature of PUR and epoxy resin or chemical characteristic also are not suitable for some senior electronics, electric parts, as integrated circuit (IC) or transistor, temperature or consumption during most probably because of perfusion are out of control, and cause the damage of these main electronic building bricks to be lost efficacy, relatively, make the manufacturing difficulty thereby the raising of its product.Again, at the above-mentioned waterproof type that is poured into enclosure interior with PUR or epoxy resin, its another problem is to be this electric circuit device, be to use as lamp series controller or optical controller and break down or main electronics or electric component when damaging, and can't be tested maintenance or be changed assembly at each assembly in the circuit or circuit, in case cause this electric circuit device to have fault or damage promptly can't carry out maintenance slightly, change brand-new electric circuit device and must buy more again separately, not only the equipment cost of increase use also causes the puzzlement in the use, and, have plastic casing in a large number and contain PUR or electric circuit device that high pollution such as epoxy resin is difficult for decomposed substance is thrown aside, will cause serious more and can't remedy the global problem of environmental pollution of rescue.

Main purpose of the present utility model, it promptly is the waterproof case that is to provide a kind of circuit arrangement, particularly groove and the fin that engages with correspondence set up at the junction surface between housing separately, makes the tortuous lengthening in its leakproof gap, and reaches the effect of inner leakproof, protection against the tide and waterproof.

Second purpose of the present utility model promptly is the waterproof case that is to provide a kind of circuit arrangement, needn't pour into PUR or epoxy resin in enclosure interior, can make enclosure interior reach the function of initiatively leakproof, protection against the tide and waterproof.

The 3rd purpose of the present utility model, it promptly is the waterproof case that is to provide a kind of circuit arrangement, when the electronics in the housing, electric component or circuit damaged, removable housing was carried out maintenance, can save equipment cost and eliminate the problem of environmental pollution that plastic casing is thrown aside in a large number.

The purpose of this utility model is to adopt following technical scheme to realize:

A kind of waterproof case of circuit arrangement, it is characterized in that, comprise: first housing and second housing, this first housing, the second housing correspondence are combined into housing, and its junction is respectively equipped with a joint portion, in be provided with a fin and groove, corresponding mutually the connection makes up, in this housing circuit arrangement is set, and is provided with a line outlet at least on first housing and second housing, its inside is provided with several grooves; One terminal, an end connection cable, the other end then is provided with several fins, to be embedded at the groove on the line outlet.

The utility model can also adopt following measure:

Be provided with fixedly fin in described first housing and second housing for the stationary transformer iron core.
