Abstract

A card edge connector includes an insulating body, multiple terminals arranged at the insulating body, plastic ear clips, and metal reinforcing members embedded in the plastic ear clips. The insulating body has a slot extending along a lengthwise direction for inserting an electronic card. Each terminal has a contact portion protruding into the slot to connect the electronic card. Each plastic ear clips has a main body and a withdrawing portion disposed below the main body. The plastic ear clip has two rotating shafts at two opposite sides of the main body. The rotating shafts are pivoted to the insulating body. The withdrawing portion is used for pushing the bottom end of the electronic card to be separated from the slot. The metal reinforcing members extend in the main body and the withdrawing portions, and has a first through hole arranged at a position corresponding to the rotating shafts.

First claim

What is claimed is:

1. A card edge connector, comprising:
an insulating body, having a slot extending along a lengthwise direction and used for an electronic card to be inserted therein;
a plurality of terminals, arranged at the insulating body, each of the terminals having a contact portion protruding into the slot to be electrically connected with the electronic card;
a plastic ear clip, having a main body and a withdrawing portion disposed at a lower end of the main body, wherein the plastic ear clip has two rotating shafts disposed at two opposite sides of the main body, the rotating shafts are pivoted to the insulating body, when the plastic ear clip rotates from a closing state to an opening state, the withdrawing portion pushes the electronic card to move outward from the slot; and
a metal reinforcing member, embedded in the plastic ear clip, wherein the metal reinforcing member extends in the main body and the withdrawing portion, the metal reinforcing member has a first through hole and a plurality of second through hole, the first through hole aligns with the two rotating shafts, and at least one of the second through holes is disposed above the two rotating shafts and at least one of the second through holes is disposed below the two rotating shafts.

2. The card edge connector of claim 1 , wherein a size of the first through hole is smaller than a size of each of the rotating shafts.

3. The card edge connector of claim 1 , wherein the first through hole is circular and is arranged coaxially with the rotating shafts.

4. The card edge connector of claim 1 , wherein the metal reinforcing member has a base portion and a first protruding portion extending from the base portion, the base portion extends in the main body, and the first protruding portion extends in the withdrawing portion.

5. The card edge connector of claim 4 , wherein the terminals are arranged at two sides of the slot, the terminals comprise a pair of oppositely positioned first terminals disposed at one end of the slot, and when the plastic ear clip is in an opening state, the first protruding portion crosses the contact portions of the first terminals in the lengthwise direction.

6. The card edge connector of claim 5 , wherein the first terminals are power supply terminals.

7. The card edge connector of claim 4 , wherein the slot has a bottom surface, the first protruding portion has an upper surface, and when the plastic ear clip is in a closing state, the upper surface is arranged to be higher than the bottom surface.

8. The card edge connector of claim 7 , wherein the insulating body has a projecting portion protruding upward from the bottom surface and used for upward supporting the bottom end of the electronic card, and when the plastic ear clip is in the closing state, the upper surface is arranged to be lower than the top surface of the projecting portion.

9. The card edge connector of claim 1 , wherein the plastic ear clip has a buckle portion extending from the main portion to the slot direction, the buckle portion is used for locking the electronic card when in the closing state, and the metal reinforcing member has a second protruding portion extending into the buckle portion.

10. The card edge connector of claim 9 , wherein the second protruding portion is provided with at least one second through hole.

11. The card edge connector of claim 1 , wherein the main body has an inner side surface and an outer side surface which are arranged correspondingly in the lengthwise direction, the main body has multiple ejector pin holes which are formed in a recessing manner from the inner side surface and the outer side surface along the lengthwise direction, and the ejector pin holes are arranged in connection with the metal reinforcing member.

12. The card edge connector of claim 1 , wherein the metal reinforcing member is in a flat shape, and a distance from a plate edge of the metal reinforcing member to a corresponding outer surface of the plastic ear clip is greater than or equal to 0.3 mm.

13. The card edge connector of claim 1 , wherein the at least one of the second through holes disposed below the two rotating shafts is arranged in the withdrawing portion.

14. The card edge connector of claim 1 , wherein the plastic ear clip has a buckle portion disposed at an upper end of the main body and used for locking the electronic card when in the closing state, the buckle portion and the withdrawing portion respectively extend from the main portion toward the slot in the lengthwise direction.

15. The card edge connector of claim 14 , wherein in a process of the plastic ear clip changing from the closing state to the opening state, the withdrawing portion urges the electronic card to form an urging point, and the urging point is always disposed within a length range of the first protruding portion in the lengthwise direction.

16. The card edge connector of claim 1 , further comprising a pressing member, wherein one end of the insulating body has a mounting portion, the plastic ear clip and the pressing member are installed at the mounting portion, the pressing member is disposed above the plastic ear clip, the plastic ear clip has at least one crimping slope, and the pressing member slides on the crimping slope to make the plastic ear clip rotate relative to the insulating body.
