Abstract
The utility model relates to a leading-out terminal structure of a solar energy photovoltaic junction box. A leading-out terminal structure of the existing solar energy photovoltaic junction box is directly matched with a plurality of parts in a screwing way, simple in structure, worse in tightness, easy to become flexible and worse in water repellency. The leading-out terminal structure comprises a leading-out terminal and a cable outside a box body. The leading-out terminal structure is characterized in that the leading-out terminal is internally provided with a hole to be connected with the cable, a step-shaped seal ring is further arranged on the cable, the outer end of the seal ring forms into an external connecting pipe, the external connecting pipe is matched with a flower basket-shaped seal piece, and the leading-out terminal is further matched with a screw cap. The conventional leading-out terminal and a screw cap are internally provided with the step-shaped seal ring and the flower basket-shaped seal piece which are tightly matched with one another, so that the connecting firmness and the tightness of the leading-out terminal of the photovoltaic junction box are effectively improved, and the leading-out terminal structure is firm in locking and better in water repellency.
Description
Technical field
The utility model relates to a kind of exit structure of photovoltaic terminal box.
Background technology
The outer leading-out terminal of existing photovoltaic terminal box directly adopts threaded, and is simple in structure, but sealing is relatively poor, and it is loosening to connect easy generation, and water proofing property is also relatively poor.
The utility model content
The utility model provides a kind of conducting block structure of improved photovoltaic terminal box to the defective that prior art exists, and can effectively improve the degree of being connected firmly of conducting block and triangular spring, strengthens heat dispersion simultaneously.
For this reason; The utility model is taked following technical scheme: a kind of exit structure of photovoltaic terminal box, comprise leading-out terminal and cable that box body is outside, and it is characterized in that establishing in the described leading-out terminal perforate and join with cable; Also be provided with a step sealing ring on the cable; The outer end of said sealing ring forms outer connecting pipe, and a described outer connecting pipe and a gaily decorated basket shape seal match, and described leading-out terminal matches with a nut again.
As preferably, have interval trough on the described gaily decorated basket shape seal, promote heat dispersion.
The utility model has been set up the step sealing ring and the gaily decorated basket shape seal of mutual close-fitting in traditional leading-out terminal and nut, effectively promoted the degree of being connected firmly and the sealing of photovoltaic junction box exit, locks firm and has the better waterproof ability.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1. box body 2. leading-out terminals 3. sealing rings 4. seals 5. nuts 6. cables 7. tube connectors 8. interval troughs.
Embodiment
The exit structure of a kind of photovoltaic terminal box as shown in Figure 1; The leading-out terminal 2 and cable 6 that comprise box body 1 outside; Establish perforate in the leading-out terminal 2 and join with cable 6, also be provided with a step sealing ring 3 on the cable 6, the outer end of sealing ring 3 forms outer connecting pipe 7; Outer connecting pipe 7 matches with a gaily decorated basket shape seal 4 again, forms external screw thread on the leading-out terminal 2 and also matches with a nut 5 again.Also have interval trough 8 on the gaily decorated basket shape seal 4.
What need particularly point out is; The mode of the foregoing description only limits to describe embodiment; But the utility model is confined to aforesaid way incessantly; And those skilled in the art can modify in the scope that does not break away from the utility model in view of the above easily, so the scope of the utility model should comprise the principle that the utility model discloses and the maximum magnitude of new feature.
