Abstract

An electrical connector comprises an insulative housing, a plurality of conductive terminals secured in the insulative housing, a metal shell shielding around the insulative housing and a magnetic element retained in the metal shell. The metal shell forms an accommodating room for receiving the magnetic element. The magnetic element has an outer surface and a recess defined on the outer surface. The metal shell has a retaining arm corresponding to the recess. The design of the recess and the retaining arm make a better retaining effectivity for the electrical connector.

Claims

1. An electrical connector comprising:

an insulative housing;

a plurality of conductive terminals secured in the insulative housing;

a metal shell shielding around the insulative housing and forming an accommodating room; and

a magnetic element retained in the accommodating room of the metal shell and having an outer surface;

wherein the magnetic element defines a recess at the outer surface, and the metal shell has a retaining arm corresponding to the recess and latching with the recess.

2. The electrical connector as claimed in claim 1, wherein the insulative housing includes a base portion and a mating portion extending forwardly from the base portion, the metal shell surrounds the mating portion and forms two said accommodating rooms aforementioned which open forwardly at two opposite sides of the mating portion, and two magnetic elements aforementioned are assembled into the accommodating rooms along a front to back direction.

3. The electrical connector as claimed in claim 2, wherein the recess includes a first inner edge, a second inner edge opposite to the first inner edge along the front to back direction, and an inner surface connecting the first inner edge with the second inner edge, a part region of the inner surface is recessed inwardly from the second inner edge in the front to back direction, the retaining arm is configured as fingerlike and rearward inserts into the recess from the metal shell.

4. The electrical connector as claimed in claim 1, wherein the magnetic element defines two said recesses at two opposite side surfaces of the outer surfaces thereof, and the metal shell has two said retaining arms engaging with the two recesses, respectively.

5. The electrical connector as claimed in claim 2, wherein the metal shell has a body portion attached to the mating portion and four side walls surrounding to form the accommodating rooms, and the insulative housing has two enhanced portions separately behind the two accommodating rooms.

6. The electrical connector as claimed in claim 5, wherein at least one of the four side walls is formed with a stop portion bending from a rear edge thereof, and the stop portion is positioned between the magnetic element and the enhanced portion.

7. The electrical connector as claimed in claim 5, wherein the metal shell has a first shell and a second shell assembled with each other, the first and second shells surround to form the accommodating rooms.

8. The electrical connector as claimed in claim 7, wherein the first shell has a first body portion, two first side walls extending horizontally and outwardly from two sides of the first body portion, two second side walls separately bending from the first side walls in a vertical direction perpendicular to the front to back direction and two third side walls separately bending inwardly and extending horizontally from the second side walls, the second shell has a second body portion and two fourth side walls bending from the two opposite sides of the second body portion in a vertical direction, the first, second, third and fourth side walls surround to form said accommodating room.

9. The electrical connector as claimed in claim 8, wherein the second shell defines a cantilever first stop portion bending outwardly from a rear edge of the fourth side wall, the first shell bends a second stop portion from a rear edge of the third side wall, the first and second stop portions are both positioned between the magnetic element and the enhanced portion and in a same plane.

10. The electrical connector as claimed in claim 9, wherein the fourth side wall stamped outwardly to form a third stop portion, and the third stop portion is configured as cantilever and is adjacent to a rear face of the second stop portion.

11. An electrical connector, comprising:

an insulative housing including a base portion and a mating portion extending forwardly from the base portion;

a plurality of conductive terminals retained in the insulative housing;

a metal shell shielding around insulative housing, the metal shell including a first shell and a second shell assembled with each other; and

a pair of magnetic elements received in the metal shell;

wherein the first and second shells surround to form a mating room and two accommodating rooms disposed at two sides of the mating room along a longitudinal direction, the three rooms are separated side by side by the second shell, the mating portion of the insulative housing is received in the mating room, and each of the magnetic elements is secured in the accommodating room by a pair of retaining structures.

12. The electrical connector as claimed in claim 11, wherein each of the magnetic elements has an outer surface, the magnetic element defines a recess recessed at the outer surface, and the metal shell defines a retaining arm engaging with the recess.

13. The electrical connector as claimed in claim 12, wherein the first shell has a first body portion and three side walls extending outwardly one by one from the first body portion, the second shell includes a second body portion and a side wall bending from the second body portion vertically, the first and second body portion and the side wall of the second shell surround to form the mating room, the four side walls of the first and second shells surround to form the accommodating room.

14. The electrical connector as claimed in claim 13, wherein each of the magnetic element has an upper surface and a lower surface opposite to the upper surface, the upper and lower surfaces both define the recess aforementioned, and the two side walls opposite to each other of the first shell has the retaining arms configured as cantilever and extending into the recesses.

15. An electrical connector comprising:

an elongated insulative housing extending along a lengthwise direction and defining a mating port exposed forwardly toward an exterior along a front-to-back direction perpendicular to said lengthwise direction, and located behind a front face lying in a plane oblique to said front-to-back direction;

a plurality of contacts disposed in the housing with contacting sections exposed in the mating port;

a metallic shell enclosing said housing with an opening exposing said mating port forwardly; and

a pair of magnets located by two opposite ends of the mating port in said lengthwise direction;

wherein

each of said magnets forms a front surface parallel to said front face.

16. The electrical connector as claimed in claim 15, wherein said front surface is coplanar with said front face.

17. The electrical connector as claimed in claim 15, wherein the shell forms a pair of accommodating rooms by two opposite ends of the mating port in the lengthwise direction to receive said pair of magnets therein, respectively.

18. The electrical connector as claimed in claim 17, wherein said pair of accommodating rooms are configured to have the corresponding magnets rearwardly assembled thereinto along said front-to-back direction, respectively.
