Abstract

A high power receptacle connector has a first insulating housing, a second insulating housing, a first terminal, a second terminal, a third terminal and a shell. The second insulating housing is mounted on the first insulating housing and has a cylinder. The first terminal is cylindrical, surrounds the cylinder and has multiple first resilient contacting tabs and a reinforcing ring formed on front ends of the first resilient contacting tabs. The second terminal is cylindrical and mounted around the cylinder and has multiple radially protruding second resilient contacting tabs. The second resilient contacting tabs increase the contacting areas, reduce the resistance of the terminals and further improve the power of the high power receptacle connector and stably hold an external plug connector.

Claims

1. A high power receptacle connector comprising:

a first insulating housing having a front end, a rear end and a cavity defined through the first insulating housing;

a second insulating housing mounted on the rear end of the first insulating housing and having a front end and a rear end and further having

a base having a front and a rear; and

a cylinder formed on and protruding forward from the front of the base and extending in the cavity of the first insulating housing;

a first terminal being cylindrical, mounted on the front end of the second insulating housing, surrounding the cylinder and having

an annular mounting tab mounted on the front end of the second insulating housing;

multiple first resilient contacting tabs formed on and protruding forward from the annular mounting tab and arranged at intervals, and each first resilient contacting tab having a front end; and

a reinforcing ring formed on the front ends of the first resilient contacting tabs;

a second terminal being cylindrical, mounted around the cylinder of the second insulating housing, surrounded by the first terminal, arranged at an interval from the first terminal and having multiple second resilient contacting tabs formed on and protruding obliquely and radially outward from the second terminal;

a third terminal mounted through the base of the second insulating housing and extending forward in the cylinder; and

a shell having an accommodating space defined in the shell and receiving the first insulating housing, second insulating housing, first terminal, second terminal and third terminal.

2. The high power receptacle connector as claimed in claim 1, wherein the cylinder of the first insulating housing has a through hole defined through the cylinder so that the third terminal extends in the through hole.

3. The high power receptacle connector as claimed in claim 2, wherein the third terminal has two prongs formed on and protruding forward from the third terminal and extending in the through hole of the cylinder.

4. The high power receptacle connector as claimed in claim 2, wherein

the second insulating housing has through mounting holes defined through the second insulating housing;

the first terminal further has a first soldering section formed on and protruding backward from the annular mounting tab;

the second terminal further has a second soldering section formed on and protruding backward from the second terminal;

the third terminal further has a third soldering section formed on and protruding backward from the third terminal; and

the first, second and third soldering sections are mounted respectively the mounting holes of the second insulating housing.

5. The high power receptacle connector as claimed in claim 2, wherein

the first insulating housing further has an assembling hole defined through the first insulating housing;

and

a light-emitting element is mounted in the assembling hole of the first insulating housing.

6. The high power receptacle connector as claimed in claim 2, wherein

a mounting bracket is mounted on the rear end of the second insulating housing and is mounted around the third soldering section of the third terminal.

7. The high power receptacle connector as claimed in claim 2, wherein

the first insulating housing further has two hooks formed on and protruding backward from the rear end of the first insulating housing;

and

the base of the second insulating housing further has two hooking holes defined through the base and respectively hooking around the hooks of the first insulating housing.
