Abstract

An electrical connector includes an insulating housing, a plurality of probe pins assembled in the insulating housing, a magnetic block and a metal shell. The insulating housing has a base and a tongue extending frontward from a front of the base. The magnetic block has an inserting hole penetrating longitudinally therethrough and matched with the tongue of the insulating housing. The metal shell includes a first metal shell and a second metal shell. The first metal shell is assembled rearward through the tongue to enclose the base, and the magnetic block sheathes the tongue in the inserting hole. The second metal shell covers a front of the magnetic block and defines a positioning window for positioning a front end of the tongue therein. The second metal shell and the first metal shell are buckled and electrically connected with each other to clamp the magnetic block therebetween.

Claims

1. An electrical connector, comprising:

an insulating housing having a base of substantially rectangular shape, a front of the base extending frontward to form a tongue, the insulating housing defining a plurality of inserting grooves longitudinally penetrating through the base and the tongue;

a plurality of probe pins inserted forward in the inserting grooves of the insulating housing respectively;

a magnetic block of a unitary block having an inserting hole penetrating longitudinally through the magnetic block and matched with the tongue of the insulating housing; and

a metal shell including a first metal shell and a second metal shell, the first metal shell being assembled rearward through the tongue to enclose the base, the magnetic block sheathing the tongue in the inserting hole, the second metal shell covering a front of the magnetic block and defining a positioning window for positioning a front end of the tongue therein and further exposing the front end of the tongue outside, the second metal shell and the first metal shell being buckled and electrically connected with each other to clamp the magnetic block therebetween.

2. The electrical connector as claimed in claim 1, wherein the first metal shell has a front plate with an inserting window opened therein and matched with the tongue, the tongue passes through the inserting window to make the front plate abut against the front of the base, top and bottom edges of the front plate protrude rearward to form a plurality of resisting plates clamping a top and a bottom of the base, and extend forward to form a pair of connecting plates attached on a top and a bottom of the magnetic block with buckle ears oppositely protruding outward on fronts thereof, two opposite side edges of the front plate extend rearward to form a pair of side plates attached on two opposite side faces of the base, the second metal shell has a cover plate with the positioning window opened therein, a pair of locking parts protrudes rearward from top and bottom of the cover plate, the cover plate is covered on the front of the magnetic block and the locking parts buckle with the buckle ears of the connecting plates.

3. The electrical connector as claimed in claim 2, wherein the two opposite side faces of the base protrude outward to form a buckle block respectively, each of the side plates defines a buckle hole buckling the buckle block therein.

4. The electrical connector as claimed in claim 2, wherein the top and the bottom of the base respectively define two receiving fillisters transversely spaced from each other, each of the resisting plates covers one of the receiving fillisters and is punched outward to form an elastic slice capable of being elastically pressed into the corresponding receiving fillister.

5. The electrical connector as claimed in claim 2, wherein the resisting plates connected with the top edge of the front plate further slantwise extend rearward to form two touching slices stretching behind the base.

6. The electrical connector as claimed in claim 2, wherein a periphery outer side of the tongue protrudes outward to form a plurality of fastening ribs spaced from one another and each extending longitudinally to connect the front of the base, a plurality of fastening gaps is apart opened in a periphery inner edge of the inserting window of the front plate and snaps the corresponding fastening ribs therein, the fastening ribs further interfere with a periphery inner sidewall of the inserting hole to secure the magnetic block around the tongue.

7. The electrical connector as claimed in claim 2, wherein the top and the bottom of the magnetic block are concaved inward to respectively define a fastening fillister penetrating longitudinally through the magnetic block for inserting the corresponding connecting plate therein.

8. The electrical connector as claimed in claim 2, wherein a periphery outer edge of the cover plate protrudes rearward to form a positioning ring surrounding the front of the magnetic block, the locking parts protrude rearward from substantial middles of rear edges of the top and bottom of the positioning ring.
