Abstract
The invention relates to a photovoltaic junction box and belongs to the technical field of photovoltaic connectors. The photovoltaic junction box comprises a box body and a connecting end, projections are arranged on the contact surface of the connecting end and the box body, and the corresponding positions of the box body are provided with grooves, and the grooves are in interference fit with the grooves. With the projections and the grooves of the connecting end and the box body, the joint of the connecting end and the box body is sealed, and the photovoltaic junction box has the advantages of excellent waterproofness and dust-proofness. As an improvement, the inner circumference of the connecting end is provided with projections at intervals, and a connecting cable and the connecting end are sealed after the connecting cable accesses into the junction box, so that waterproofness and dust-proofness of the junction box are improved.
Description
Technical field
The invention belongs to photovoltaic connector technical field, particularly relate to a kind of photovoltaic junction box.
Background technology
Terminal box plays very important effect in solar module, the development of making rapid progress along with photovoltaic industry, and increasing sight has turned to it terminal box; Because the electricity that solar cell produces can not only be transferred in external circuit and go by easily, it is also solar module " bodyguard " simultaneously.
The cross-cutting comprehensive design that terminal box is collection electrical design, Machine Design combines with material science; When terminal box is served as " bodyguard ", it utilizes the performance of diode self to make solar module when other unfavorable factors such as shading, current mismatch occur, and it can also be kept to work, suitably reduce loss.
Due to the characteristic of itself, progressively pay close attention to the increasing people of field of solar energy " bodyguard " of this solar module, along with the development of photovoltaic market, the brand of terminal box also with more than get up, product quality is also uneven, and terminal box produced problem in system application also gets more and more.
Summary of the invention
A kind of photovoltaic junction box of the present invention, the technical solution used in the present invention is, a kind of photovoltaic junction box comprises box body and link, and the joint face that described link contacts with box body is provided with projection, the corresponding site of described box body is provided with groove, and described projection and described groove are interference fit.
Photovoltaic junction box of the present invention, by arranging the projection and groove that cooperatively interact on link and box body respectively, making the junction of link and box body be formed and sealing, making photovoltaic junction box reach the beneficial effect of good waterproof and dustproof.
Further improve as the present invention, the inner peripheral surface of described link is interval with projection, after stube cable thereto, stube cable and link are formed and seal, and make photovoltaic junction box enhance the function of water proof and dust proof.
Accompanying drawing explanation
Fig. 1 is photovoltaic junction box cross-sectional view of the present invention;
Fig. 2 is I place partial enlarged drawing in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the present invention made and further illustrating.
As shown in the figure, photovoltaic junction box of the present invention comprises box body 1 and link 2, and the joint face that described link contacts with box body is provided with projection, and the corresponding site of described box body is provided with groove, and described projection and described groove are interference fit.
As preferably, the inner peripheral surface of described link is interval with projection, after stube cable 3 thereto, stube cable and link are formed and seal, and make photovoltaic junction box enhance the function of water proof and dust proof.
The description of above embodiment is comparatively concrete, detailed; but therefore can not be interpreted as the restriction to this patent scope; it should be noted that; for the person of ordinary skill of the art; without departing from the inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (2)
1. a photovoltaic junction box, comprises box body and link, it is characterized in that: the joint face that described link contacts with box body is provided with projection, and the corresponding site of described box body is provided with groove, and described projection and described groove are interference fit.
2. photovoltaic junction box according to claim 1, is characterized in that: the inner peripheral surface of described link is interval with projection.
