Abstract: A vehicle USB Type-C connector, comprising a cable end member and a board end member engaged together; the CPA is inserted into the engagement groove; the PCB attached male head has an end protruding from a cavity opening on one end of the cable end plastic shell cavity; the encapsulated outer mold is inserted into a cavity opening on another end of the cable end plastic shell cavity; the encapsulated outer mold has an engagement side on two sides thereof and inserted into the lateral engagement groove; the upper lock plate is engaged above the engagement groove, the lower lock plate is inserted into the engagement groove, and the CPA is fastened with the cable end member. The present invention reduces the on-board height and strengthens the liability after engagement.

Abstract: A new type of defoliant and the application thereof, specifically the application of a polyether compound in the preparation of defoliant, belonging to the technical field of pesticides. At least one of the polyether compound shown in Formula I (R1O(CH2CHOH)nR2) or salts thereof is used for preparation of defoliants or defoliation synergists, wherein, the R1 is a hydrocarbyl or a phenolic group; the R2 is —H, —O(CH2CHOH)mH or —O(CH2CH2CHOH)mH; the n is 1-50, and m is 1-50. The compound is a new defoliant featured with low cost, convenient usage and favorable defoliation effect, and it is safe for the environment.

Abstract: The prevent invention relates to connector fields, and more particularly, to an engagement structure of Ethernet connector for vehicle. The plug and the socket are combined and engaged; the plug shell mounted around an outer periphery of the male terminal assembly; the plug shell including a lock plate and a lock seat. When the plug is combined with the cable end socket, the plug shell is inserted into the cable end socket shell, with the circular male terminal combined with the circular female terminal. When the lock plate is pushed from the second end toward the first end of the rail, the ramp elastically crosses over the second end of the bolt member to be engaged between the ramp and the protrusion, and the hook member is engaged with the outer hook.

Abstract: A self-lock structure of Ethernet connector for vehicle, includes a plug self-lock member and a cable end socket self-lock member. When the plug self-lock member and the cable end socket self-lock member are at a first engagement stage, the fastener is inserted into the outer shell, the outer hanger is engaged with the first groove, the first protrusion, the second protrusion, and the inner hanger are engaged with the second groove, the third groove, and the fourth groove, respectively, and the elastic plate is not in a forced status. When the plug self-lock member and the cable end socket self-lock member are at a second engagement stage, the fastener is further inserted into the outer shell, and the first protrusion and the second protrusion are further engaged, respectively, and the elastic plate is in a forced status, enhancing the fastening stability.

Abstract: An on-vehicle Ethernet connector includes a housing, a terminal, a shield member, and an ESD casing; the housing formed in a barrel shape and having a U-shaped protection structure; the terminal inserted on a bottom of the housing; the shield member inserted in the pillar bodies; the ESD casing mounted around the housing; the U-shaped protection member disposed in the housing and having a plurality of pillar bodies connected and arranged around the terminal; and a sectional view of the plurality of pillar bodies around the terminal being formed in a U shape. The U-shaped protection structure surrounding the terminal prevents the terminal from being accidentally touched, thus increasing the stability and security of the connector. The shield member shields around the terminal. The U-shaped protection structure formed of plastic material provides dust-proof, water-proof, insulation, and accidental contact prevention.

Abstract: The present invention relates to a ball-throwing scoop for interaction with a pet, comprising a scoop body and a handle. The scoop body includes a scoop opening, two sides and a base portion. The scoop body resembles a smaller half of a circular tube or approximately circular tube longitudinally cut off, the longitudinal central axis y of which is an arc having a larger radius R; r is used to denote the radius of the smaller half of the circular tube, R>>r; the base portion of the scoop body is connected to the handle in the shape of a hollow cylinder, the central axis of the handle obliquely intersects the longitudinal central axis of the scoop body, a cavity of the handle can store liquid or solid pet drinks/foods, especially a cylindrical biscuit box.
