## Abstract

An electrical connector adapted for being electrically connected with a PCB stably, includes an insulating housing defining a plurality of terminal passageways for receiving terminals and at least one through-hole located at one side of the terminal passageways. The insulating housing has two opposite holding blocks which defines two guiding recesses facing each other for locating the PCB. A shell encircles the insulating housing and defines at least one pressing slice passing through the through-hole and pressing against one surface of the PCB. Each of the terminals has a soldering portion exposed out of the terminal passageway and pressing against the other surface of the PCB.

## Claims

### Claim 1

An electrical connector adapted for being electrically connected with a printed circuit board, comprising:
an insulating housing having a basic body which has two opposite holding blocks extending from two opposite ends of the basic body and a mating portion extending from one side of the basic body opposite to the holding blocks, the basic body defining at least one through-hole which penetrates through the basic body, the mating portion defining a plurality of terminal passageways rowed transversely with respect to a mating direction of the connector, the terminal passageways which penetrate through the basic body and the mating portion are located adjacent to one side of the through-hole, the two holding blocks defining two guiding recesses facing each other for locating the printed circuit board;
a plurality of terminals received in the corresponding terminal passageways, each of the terminals having a soldering portion extending outside of the terminal passageway for being soldered to one surface of the printed circuit board; and
a shell encircling the mating portion of the insulating housing, the shell having at least one pressing slice passing through the through-hole of the basic body for pressing against and electrically contacting a grounding point defined on the other surface of the printed circuit board.

### Claim 2 (depends on 1)

The electrical connector as claimed in claim 1, further comprising a pair of fixing elements respectively fixed into the two holding blocks, each of the fixing elements has an extending portion exposed out of the holding block for pressing against and electrically contacting another grounding point defined on the PCB.

### Claim 3 (depends on 2)

The electrical connector as claimed in claim 2, wherein the fixing element has a main portion received in a receiving recess defined in the holding block, the extending portion extends from the main portion.

### Claim 4 (depends on 3)

The electrical connector as claimed in claim 3, wherein a bottom of the receiving recess defines a receiving cavity extending towards an interior of the holding block, the main portion of the fixing element has a fixing portion which extends in an opposing direction with the extending portion and is inserted into the receiving cavity for fixing the fixing element to the insulating housing.

### Claim 5 (depends on 3)

The electrical connector as claimed in claim 3, wherein the main portion of the fixing element defines a slender elastic portion extending in a direction opposite to the extending portion, the holding block defines a containing groove extending from a bottom of the receiving recess and penetrating through the basic body and extending into the mating portion for receiving the elastic portion.

### Claim 6 (depends on 5)

The electrical connector as claimed in claim 5, wherein the elastic portion of the fixing element has a projection projecting out of the containing groove and a receiving slot formed in the shell.
