Abstract: A connector housing includes a housing body and a first snap lock. The housing body has a row of first insertion holes, and a first snap slot. The first snap slot is in communication with the row of first insertion holes. Each first insertion hole receives one first terminal of a row of first terminals. The first snap lock has a first cantilever connected to the housing body, and a first hook at a tail end of the first cantilever. The first snap lock moves between a locked position and an unlocked position. A row of first ribs respectively corresponding to the row of first insertion holes are formed on the first hook.

Abstract: A position retaining member is adapted to be inserted into a connector housing and adapted to be moved between a final lock position and a pre lock position. The position retaining member includes a cantilever part and a pressing part. When the position retaining member is in the final lock position, the cantilever part is adapted to be pressed against an elastic buckle of the connector housing to hold the elastic buckle in a locking position engaged with a protrusion of a mating housing of a mating connector. When the position retaining member is in the pre lock position, the pressing part is adapted to press the elastic buckle to an unlocking position separated from the protrusion of the mating housing, allowing the connector housing to be pulled out from the mating housing.

Abstract: A method for extracting high-quality krill oil from krill includes the following steps: S1. performing extraction on krill with an organic solvent, and collecting an extracting solution; S2. adding alkaline water to the extracting solution to enable a free fatty acid to form a fatty acid salt to be separated from an oil phase, and performing oil-water phase separation and collecting the oil phase; and S3. purifying the oil phase to obtain the high-quality krill oil. In the present application, the preparation process for krill oil is optimized, organic solvent extraction and alkali refining are ingeniously combined, and process parameters are adjusted and optimized, thereby reducing the acid value of krill oil, and also ensuring the content of active ingredients such as phospholipid and astaxanthin in krill oil to the greatest extent, and improving the quality of krill oil.
