The front end of above-mentioned described sleeve has otch.
Above-mentioned described sleeve is the cylinder cone, and cylinder is a cone.
Above-mentioned described tail portion of terminal is with groove, the wallboard in the both sides of groove.
The direct soldering of end the end of a thread of above-mentioned described lead-in wire is fixed on the groove the inside.
On end the end of a thread connecting line ear of above-mentioned described lead-in wire, the line ear is nested in groove, and pin gets up two wallboards and the connection of line ear.
Above-mentioned described cylinder is plugged into the sleeve pin the inside of serial port hub tail, and hollow sleeve is wrapped in the outside of sleeve pin.
Above-mentionedly saidly protective jacket is installed in several sleeve pins and terminal outside, serial port hub tail.
The afterbody of above-mentioned described lead-in wire couples together two or many wires through the double team terminal.
Insulating cement is coated in end the end of a thread of above-mentioned described terminal, lead-in wire, line ear outside.
The front end of above-mentioned described cylinder is provided with chamfering.
The present invention compared with prior art has following effect:
1) top of terminal of the present invention is a hollow sleeve, is provided with in hollow sleeve the inside and patches cylinder, forms the gap between sleeve and the cylinder; During installation; Cylinder is plugged into the sleeve pin the inside of serial port hub tail, and hollow sleeve is wrapped in the outside of sleeve pin, makes firm and reliable connection; Be difficult for getting loose, ensure that effectively energising is difficult for being interrupted;
2) terminal of the present invention 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 with neat, safe.
3) sleeve is that the little rear end of front end is big, and cylinder also is that the little rear end of front end is big, and 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 lead-in wire can rotate freely under the prerequisite of holding circuit path like this, 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 through soldering, and the line ear is nested in groove, and pin gets up two wallboards and the connection of line ear.
5) afterbody of lead-in wire couples together two or many wires through the double team terminal, thereby simplified structure is electrically connected two or many wires through 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.
