Abstract: A stable female terminal comprises a substrate. Two side edges of the front end of the substrate are turned to form two opposite elastic pieces. A slot allowing a male terminal to be inserted therein is formed between the two elastic pieces. The two elastic pieces draw close to each other to form an elastic jaw used for clamping two sides of the male terminal inserted into the slot. A female terminal external connection part is formed at the rear end of the substrate. Contacts have a large positive force when the male terminal and the female terminal are connected, so that the male terminal and the female terminal can be in contact more stably and reliably, and larger currents can pass through the male terminal and the female terminal.

Abstract: An insulated electrical connector formed by one-time injection molding is disclosed. A base of each metal female terminal has two edges extending upward and inclining relative to each other to form elastic clamping pieces, and an edge extending outwards to form a weld leg. An insulated rubber core is formed on the metal female terminals by one-time injection molding. The bases are embedded in the insulated rubber core. The elastic clamping pieces are received in cavities of the insulated rubber core. Insertion holes corresponding to the elastic clamping pieces are formed in bottoms of the cavities. Conical guide-in faces are formed at bottoms of the insertion holes. The weld legs stretch out of the insulated rubber core. The insulated electrical connector is convenient to install and realizes stable electric connection.

Abstract: A method and system for writing trajectory synchronization among multiple clients are disclosed. The method includes: receiving (S10) segmented writing trajectory data of a real-time writing trajectory transmitted in segments by each transmitting end; forwarding (S20) each segment of the segmented writing trajectory data to each receiving end in real time respectively, where the segmented writing trajectory data is received asynchronously and restored into a real-time writing trajectory by each receiving end; receiving (S30) complete writing trajectory data of a complete writing input transmitted by each transmitting end; and forwarding (S40) the complete writing trajectory data transmitted by each transmitting end to each receiving end, where the complete writing trajectory data is received synchronously and inserted into an interface for display by each receiving end.

Abstract: The lamp socket includes a connecting seat, a lamp cap, a first conductive wire and a second conductive wire. The connecting seat has a first passage provided therein, a first threaded section for thread connection with a lamp and an accommodating portion or hole in the first threaded section. The lamp cap is detachably provided at the connecting seat, and has a first conductive region and a second conductive region, the second conductive region having a second threaded section adapted to the first threaded section. A thread gap is formed between the first threaded section and the second threaded section. A limiting portion which may be formed as a mass enlargement at the end of the first wire cooperates with the accommodating portion or hole to prevent pull out of the wire from the thread group.

Abstract: Dendritic polymers with enhanced amplification and interior functionality are disclosed. These dendritic polymers are made by use of fast, reactive ring-opening chemistry (or other fast reactions) combined with the use of branch cell reagents in a controlled way to rapidly and precisely build dendritic structures, generation by generation, with cleaner chemistry, often single products, lower excesses of reagents, lower levels of dilution, higher capacity method, more easily scaled to commercial dimensions, new ranges of materials, and lower cost. The dendritic compositions prepared have novel internal functionality, greater stability (e.g., thermal stability and less or no reverse Michael's reaction), and reach encapsulation surface densities at lower generations. Unexpectedly, these reactions of polyfunctional branch cell reagents with polyfunctional cores do not create cross-linked materials.
