Description

A kind of photovoltaic conjunction box used for ceramic tile that generates electricity

Technical field

The present invention relates to the ceramic tile field of can generating electricity, be particularly useful for small size, low pressure low current ceramic tile assembly is in order to draw the ceramic tile electric current.

Background technology

In order to tackle energy crisis, people have used various existing technology to produce the electric energy of environmental protection, and manage itself and building are connected.Such as power generation tile, photovoltaic curtain wall etc.The ceramic tile that can generate electricity also is a kind of noticeable product wherein, because it can apply to the interior wall face of building, compared with the roof, door and window and so on is limited utilizes area, has very large advantage to form the distributed arrangement of green energy resource.

The ceramic tile that can generate electricity at present has following several, utilizes coating to make the photovoltaic ceramic tile of ceramic tile generating, but the pressure ceramic tile that the power generation solar ceramic tile that existing solar cell is encapsulated with ceramic tile and the concussion that utilizes sound wave to produce are generated electricity.Because the common area of ceramic tile is less, and existing technology makes the electric energy that produces on the unit are also less, forming it needs more terminal box, and the less characteristics of the volume requirement of butted line box, common electrical terminal block or photovoltaic junction box are not particularly suitables.Following scheme will design a kind of photovoltaic junction box of better this series products of adaptation, make it to be convenient to be applied to produce.

Summary of the invention

Goal of the invention: the green energy resource new product that the present invention is directed to small size, the low-voltage current ceramic tile that can generate electricity need to be used small-power, a fairly large number of electric current ejector, and design adapts to the photovoltaic junction box of this series products.

Technical scheme: the present invention includes box body, binding post, external electrode lead-in wire, bypass diode are provided with the internal wiring box body in the wherein said box body, be used for connecting internal electrode lead-wire; Be provided with the external connection box body in the described box body, be used for connecting the external electrode lead-in wire; Described internal wiring box body and external connection box body are designed to connected structure, connect interior external circuit thereby be used for connecting interior outer terminal.

Wherein said internal and external electrode lead-in wire is the flexible electrode material with the certain-length of insulative water-proof protective layer; can guarantee that like this terminal box blow-by lives internal electrode lead-wire; still can owing to the internal wiring road imports moisture in the ceramic tile of encapsulation, not make the placement of terminal box more flexible simultaneously yet.

The main cavity of a semicircle is arranged in the wherein said internal wiring box body, be used for holding internal electrode lead-wire.Have two draw-in grooves that communicate with main cavity in the described internal wiring box body, be used for respectively holding positive and negative internal electrode lead-wire.The metallic elastic fastener of dovetail groove shape is housed in the draw-in groove in the described internal wiring box body, under certain pressure, can blocks internal electrode lead-wire.

One of them preferred version is to be used in the described internal wiring box body being provided with arc-shaped protrusions with the position of external connection box body phase clamping, in order to block described box body.Position corresponding to described interior[exterior arc-shaped protrusions is provided with deep-slotted chip breaker, in order to hold arc-shaped protrusions.

As one of them preferred version, in deep-slotted chip breaker, can be provided with seal groove, and be provided with therein O-ring seal, with further enhanced leaktightness effect.

Wherein outer terminal is sealed to one with the part that the external electrode lead-in wire is connected by described external connection box body, guarantees that external circuit is path.

The part of the outstanding box body of wherein said outer terminal when described box body phase clamping, can stretch into and tightly suppress the elasticity draw-in groove in the draw-in groove, makes interior outer terminal form path.

As one of them preferred version, described bypass diode partial design is exposed outside the terminal box, to strengthen its radiating effect.

Useful achievement: a kind of photovoltaic conjunction box used for ceramic tile that generates electricity disclosed in this invention, need to use small-power for the green energy resource new product of small size, the low-voltage current ceramic tile that can generate electricity, a fairly large number of electric current ejector, design a kind of body less, the reliable terminal box of performance simple in structure.When connecting terminal box, only need to insert internal electrode lead-wire in the main cavity in the described internal wiring box body, utilize the metallic elastic fastener in the draw-in groove to fix respectively positive and negative internal electrode lead-wire, then two box portion are plugged in together and can realize its connection function.Compared with the terminal box of routine, save the time of outer terminal in the welding, also avoid the circuit bad connection problem that is caused by welding quality.Simultaneously, this terminal box can be done very littlely, in the process of carrying out architecture production, this terminal box can be put in the pressuring line groove, both has been conducive to wiring, also can fully guarantee the quality problems of its contact.And this terminal box is lower owing to cost, and is not fixed on the ceramic tile assembly with silicone adhesive, when one of them terminal box breaks down, can directly cut off internal electrode lead-wire, uses a complete new terminal box instead, safeguards very easy.
