Signal Terminal, Charging End Assembly and Charging Base

Abstract

A charging assembly for a charging base comprises a charging end assembly detachably connectable to a connecting end assembly to form the charging base. The charging end assembly includes a charging end housing defining a plurality of first openings, and a plurality of signal terminals received in a corresponding one of the plurality of first openings. Each signal terminal includes a main body and a guide leg extending from an end thereof. Each guide leg contracting radially inward relative to an outer wall of the main body and adapted to bias a spring sheet of a lead frame and guide the outer wall of the main body to be inserted into contact with the spring sheet.

         9 . The charging assembly according to  claim 1 , further comprising a connecting end assembly detachably connected to the charging end assembly and including a connecting end housing defining a plurality of second openings receiving respective front ends of each of the plurality of signal terminals. 
     
     
         10 . The charging assembly according to  claim 1 , further comprising:
 a plurality of front power terminals arranged in a plurality of third openings formed through the charging end housing; and   a plurality of rear power terminals arranged in a plurality of forth openings formed through the connecting end housing, the front and rear terminals detachably electrically connected to one another with the connecting end assembly connected to the charging end assembly.   
     
     
         11 . The charging assembly according to  claim 1 , wherein each of the plurality of signal terminals is detachably fixed in one of the plurality of first openings. 
     
     
         12 . A signal terminal for a charging base, comprising:
 a main body; and   a guide leg extending from an end of the main body and contracting radially inward relative to an outer wall of the main body, the guide leg adapted to bias a spring sheet of a lead frame and guide the outer wall of the main body to be inserted into contact with the spring sheet.   
     
     
         13 . The signal terminal according to  claim 12 , wherein the guide leg extends from a rear end of the main body of each of the signal terminals. 
     
     
         14 . The signal terminal according to  claim 12 , further comprising a second guide leg adapted to bias a respective one of a pair of the spring sheets of the lead frame. 
     
     
         15 . The signal terminal according to  claim 14 , wherein the pair of guide legs are arranged radially opposite to each other. 
     
     
         16 . The signal terminal according to  claim 15 , wherein the main body of each signal terminal is substantially cylindrical.
