The utility model content:
The technical problems to be solved in the utility model is, provides a kind of Non-return ring of being convenient to pack into and connect the photovoltaic connector of housing.
Technical solution of the present utility model is, a kind of photovoltaic connector of following structure is provided, comprise anode connection terminal and negative pole link, described anode connection terminal comprises anodal housing, anodal contact pin and the anodal Non-return ring of connecting, and the negative pole link comprises that negative pole connects housing, negative pole contact pin and negative pole Non-return ring; The described anodal maximum outside diameter that connects the import internal diameter of housing greater than anodal Non-return ring, the anodal connection in the housing import is provided with anodal spacing collar, and the internal diameter of described anodal spacing collar is at least less than the maximum outside diameter of anodal Non-return ring; Described negative pole connects the maximum outside diameter of the import internal diameter of housing greater than negative pole utmost point Non-return ring, and negative pole connects in the housing import and is provided with the negative pole spacing collar, and the internal diameter of described negative pole spacing collar is at least less than the maximum outside diameter of negative pole Non-return ring.
Adopt after the above structure compared with prior art, the utlity model has following advantage: adopt the utility model structure, increased the import internal diameter of both positive and negative polarity connection housing, made things convenient for the installation of both positive and negative polarity Non-return ring, and adopt the both positive and negative polarity spacing collar spacing to the both positive and negative polarity Non-return ring, prevent that the both positive and negative polarity Non-return ring from skidding off from the import that connects housing, both made things convenient for the installation of Non-return ring, unlikely again spacing collar is run out of, and has prevented because of assembling Non-return ring excessive connection housing or the Non-return ring of damage of exerting oneself.
As improvement, described both positive and negative polarity spacing collar is connected the removable connection of housing respectively with both positive and negative polarity, like this, both made things convenient for packing into of Non-return ring, also made things convenient for the dismounting of whole photovoltaic connector, if the Non-return ring damage, it is just passable only to need to change Non-return ring, and prior art then is difficult to have damaged the Non-return ring taking-up and changes.
