2) the utility model terminal is a standard component, and volume is little, directly is plugged on the sleeve pin the inside of serial port hub tail, need not welding, therefore avoids welding rosin joint and the short circuit problem that brings, reliable in quality, and compare standard and neat, safe.
3) sleeve is that the little rear end of front end is big, cylinder also is that the little rear end of front end is big, cylinder is plugged into the sleeve pin the inside of serial port hub tail, the sleeve pin is outwards expanded, but by the hollow sleeve parcel of terminal, the sleeve pin outwards expands the hollow sleeve of terminal when outwards expanding to the sleeve pin, therefore all the time, the sleeve pin closely cooperates with the cylinder and the sleeve of terminal all the time, connects more solid and reliable; The front end of the sleeve that terminal is hollow has otch, makes things convenient for sleeve outwards to expand.
4) tail portion of terminal is with groove, and the wallboard in the both sides of groove, end the end of a thread of lead-in wire are nested in the groove the inside, and going between like this can rotate freely under the prerequisite of holding circuit path, has increased flexibility, has also solved the problem of local space deficiency; End the end of a thread of lead-in wire is fixed on end the end of a thread connecting line ear of groove the inside or lead-in wire by soldering, and the line ear is nested in groove, and pin gets up two wallboards and the connection of line ear.
5) Yin Xian afterbody couples together two or many wires by the double team terminal, thereby simplified structure is electrically connected two or many wires by a terminal and a lead-in wire.
6) insulating cement is coated in end the end of a thread of terminal, lead-in wire, line ear outside, cooperates conducting position to award protection it, and playing increases adhesion and effect insulated from each other is arranged.
