Abstract

An electrical plug connector includes an insulated housing, conductive terminals, and a metallic shell. The insulated housing includes a base portion and recessed portions configured at two sides of the base portion. The conductive terminals are held at the base portion. The metallic shell includes a body shell, two stopping pieces, two holding portions, and an extending sheet. The body shell encloses the base portion and defines two engaging grooves. The stopping pieces are protruded out of lateral inner surfaces of the body shell to engage with the recessed portions. The holding portions allow connections of portions of the body shell spaced by the engaging groove and hold two sides of the circuit board from moving. Engaging pieces of the extending sheet are engaged with the circuit board to prevent the circuit board from being detached from the insulated housing to prevent charging or data transmission failure.

First claim

What is claimed is:

1. An electrical plug connector, comprising:
an insulated housing comprising a base portion, a tongue portion, and a plurality of recessed portions, wherein the tongue portion is extended forward from the base portion in a rear-to-front direction, an inserting groove is defined at the surface of the tongue portion, the recessed portions are respectively configured at two sides of the base portion;
a plurality of conductive terminals respectively held at the base portion and the tongue portion, one of two ends of each of the conductive terminals located in the inserting groove, and the other end of each of the conductive terminals extended out of the base portion; and
a metallic shell partially enclosing the insulated housing, wherein the metallic shell comprises:
a body shell partially enclosing the base portion, wherein two engaging grooves are respectively defined through two sides of the body shell;
two stopping pieces respectively protruded out of two lateral inner surfaces of the body shell to engage with the recessed portions;
two holding portions respectively configured at the two sides of the body shell and near to the engaging grooves, each of the holding portions comprises a bent sheet and an inward depressed portion, the bent sheet is connected between a portion of the body shell near to one of two opposite inner walls of the engaging groove and a portion of the body shell near to the other inner wall of the engaging groove, and the inward depressed portion is formed as an inner surface of the bent sheet; and
an extending sheet extended outward from a rear of the body shell, wherein a plurality of engaging pieces extend from two sides of the extending sheet and are bent toward each other.

2. The electrical plug connector according to claim 1 , wherein the metallic shell further comprises a protruded portion defined at the outer surface of the extending sheet.

3. The electrical plug connector according to claim 1 , wherein the metallic shell comprises a wire clamping member and a plurality of strengthening portions, the wire clamping member is extended outward from the extending sheet, and the strengthening portions are formed between the wire clamping member and the extending sheet.

4. The electrical plug connector according to claim 1 , further comprising a circuit board, wherein one of two ends of the circuit board is inserted into the body shell, and a top surface and a bottom surface of two sides of the circuit board are respectively abutted against the inner walls of the engaging grooves.

5. The electrical plug connector according to claim 4 , wherein the two sides of the circuit board are respectively protruded from the two engaging grooves and held by the two inward depressed portions.

6. The electrical plug connector according to claim 5 , wherein the distance between the inner walls of the inward depressed portions is greater than the distance between the outer surfaces of the body shell.

7. The electrical plug connector according to claim 4 , wherein the engaging pieces are respectively engaged with the two sides of the other end of the circuit board and abutted against the top surface of the circuit board.

8. The electrical plug connector according to claim 7 , wherein the extending sheet comprises a plurality of sidewalls respectively abutted against the bottom surface of the circuit board.

9. The electrical plug connector according to claim 4 , wherein the metallic shell further comprises an enclosing shell, the enclosing shell comprises a body portion and two positioning plates extended outward from the body portion, the body portion encloses the tongue portion, the positioning plates are engaged with the base portion.

10. The electrical plug connector according to claim 9 , wherein the circuit board comprises a plurality of terminal contacts and a ground contact, the other ends of the conductive terminals are respectively connected to the terminal contacts, the enclosing shell comprises a ground leg extended from one of the positioning plates and connected to the ground contact.

11. An electrical plug connector, comprising:
an insulated housing comprising a base portion, a tongue portion, and a plurality of recessed portions, wherein the tongue portion is extended forward from the base portion in the rear-to-front direction, the recessed portions are respectively configured at two sides of the base portion;
a plurality of conductive terminals respectively held at the base portion and the tongue portion, one of two ends of each of the conductive terminals located in the tongue portion, and the other end of each of the conductive terminals extended out of the base portion; and
a metallic shell partially enclosing the insulated housing, wherein the metallic shell comprises:
a body shell partially enclosing the base portion, wherein two engaging grooves are respectively defined through two sides of the body shell;
two stopping pieces respectively protruded out of two lateral inner surfaces of the body shell to engage with the recessed portions;
two holding portions respectively configured at the two sides of the body shell and near to the engaging grooves, each of the holding portions comprises a bent sheet and an inward depressed portion, the bent sheet is connected between a portion of the body shell near to one of two opposite inner walls of the engaging groove and a portion of the body shell near to the other inner wall of the engaging groove, and the inward depressed portion is formed as an inner surface of the bent sheet; and
an extending sheet extended outward from the rear of the body shell, wherein a plurality of engaging pieces are extended from two sides of the extending sheet and bent toward each other.

12. The electrical plug connector of claim 11 , further including:
an inserting groove at the surface of the tongue portion, the one of two ends of the conductive terminals held at the tongue portion located in the inserting groove.
