Shielding connector

Abstract

A shielding connector includes an electrical connector body and a shielding casing. The electrical connector body includes a main body for being mounted onto a circuit board, and a mating portion extending from the main body and used for mating with a mating connector. The shielding casing wraps the periphery of the main body, and has a mounting portion fixed onto the circuit board. The mounting portion includes a first soldering portion for being fixed to a solder pad on a surface of the circuit board in a surface mounting manner, and a second soldering portion. The second soldering portion has an insertion portion for being soldered into a soldering hole on the circuit board, and a contact portion for being soldered to a solder plate surrounding the soldering hole on the surface of the circuit board. The contact portion and the first soldering portion are connected.

What is claimed is: 
     
         1 . A shielding connector, comprising:
 an electrical connector body, comprising a main body for being mounted onto a circuit board, and a mating portion extending from the main body for mating with a mating connector; and   a shielding casing, wrapping a periphery of the main body, and having a mounting portion for being fixed onto the circuit board, the mounting portion comprising:
 a first soldering portion, for being fixed to a solder pad on a surface of the circuit board in a surface mounting manner; and 
 a second soldering portion, having an insertion portion for being soldered and fixed into a soldering hole provided on the circuit board, and a contact portion for being soldered and fixed to a solder plate surrounding the soldering hole on the surface of the circuit board, the contact portion and the first soldering portion being connected. 
   
     
     
         2 . The shielding connector of  claim 1 , wherein the mounting portion is disposed at a plate edge of the shielding casing. 
     
     
         3 . The shielding connector of  claim 1 , wherein the shielding casing comprises at least one first side wall extending toward the circuit board along a side wall of the main body, and the mounting portion is disposed at a plate edge of the first side wall that is close to the circuit board. 
     
     
         4 . The shielding connector of  claim 3 , wherein a plurality of first soldering portions are disposed at the plate edge of the first side wall, and one second soldering portion is disposed at each of two opposite ends of each of the first soldering portions. 
     
     
         5 . The shielding connector of  claim 3 , wherein the shielding casing further comprises at least one second side wall extending toward the circuit board, the second side wall and the first side wall are adjacent and jointly wrap the side wall of the main body, and a third soldering portion used for being fixed onto the surface of the circuit board in the surface mounting manner is formed at a plate edge of the second side wall close to the circuit board. 
     
     
         6 . The shielding connector of  claim 3 , wherein the first side wall extends along the side wall of the main body to encircle the entire main body, and the mounting portion encircles the periphery of the main body. 
     
     
         7 . The shielding connector of  claim 1 , wherein a reserved portion is depressed from the mounting portion toward a direction away from the circuit board, and a gap exists between the reserved portion and the circuit board to reserve a space for a conducting circuit on the circuit board. 
     
     
         8 . The shielding connector of  claim 1 , wherein the mounting portion further comprises a fourth soldering portion for being fixed onto the surface of the circuit board in the surface mounting manner, and the fourth soldering portion is connected to neither the first soldering portion nor the second soldering portion. 
     
     
         9 . The shielding connector of  claim 1 , wherein one second soldering portion is disposed at each of two opposite ends of the first soldering portion, and each of the second soldering portions has one contact portion connected to the first soldering portion. 
     
     
         10 . The shielding connector of  claim 1 , wherein the second soldering portion comprises two contact portions located respectively at two opposite sides of the insertion portion, and each of the contact portions is connected to one first soldering portion. 
     
     
         11 . The shielding connector of  claim 1 , further comprising:
 a metal casing sheathed on the mating portion; and   a shielding sheet disposed on an outer side surface of the mating portion, comprising:
 an elastic sheet bending from one end of the shielding sheet and entering a mating cavity to contact a metal housing of the mating connector, wherein the mating cavity is formed in the mating portion for the mating connector to be inserted therein; and 
 an arm portion bending from another end of the shielding sheet toward the metal casing and elastically urging the metal casing. 
   
     
     
         12 . The shielding connector of  claim 11 , wherein the elastic sheet comprises an opening at a middle portion thereof, and the opening widens gradually from a root portion of the elastic sheet toward a free end of the elastic sheet. 
     
     
         13 . The shielding connector of  claim 11 , wherein the electrical connector body comprises:
 an insulating seat, having a plurality of reserved slots running through a surface thereof; and   a plurality of conducting terminals disposed in the insulating seat, each having a conducting portion bending from one end thereof for electrically connecting the mating connector,   wherein the reserved slots correspond to free ends of the conducting portions, and the shielding sheet comprises a through-hole corresponding to the reserved slots.   
     
     
         14 . The shielding connector of  claim 13 , further comprising an insulating sheet covering an outer side of the shielding sheet, the insulating sheet correspondingly covering the through-hole of the shielding sheet.
