Further, the connecting member is assembled downward from the receiving groove into the mounting hole.

Further, a pair of notches are recessed inwardly on both sides of the lower portion of the holding portion corresponding to the position of the elastic arm, and the elastic arm can be received into the notch by an external force.

Further, the elastic arm includes a bending portion and an arm body extending upward from the bending portion parallel to the holding portion, and the bending portion protrudes outward from the two sides of the holding portion.

Further, when the elastic arm is freely extended, between the arms of the two elastic arms The distance is greater than the width of the communication hole.

Further, the receiving groove and the stopping groove are both wider than the communication hole, and the width of the receiving groove is larger than the width of the stopping groove.

Further, the insulative housing includes two end portions and a foolproof portion away from one end portion thereof in the longitudinal direction, and the mounting holes are disposed in the anti-slipping portions and end portions away from each other.

Further, the two sides of the limiting portion of the connecting member are recessed inwardly.

Compared with the prior art, the present invention has the following effects: the new card edge connector inserts the connecting member in the foolproof portion and the end wall not only can enhance the strength of the foolproof portion and the end wall, but also the assembly of the connecting member is adopted. The manner of inserting from top to bottom is simple and convenient, and the structure in which the limiting portion of the connecting member and the elastic arm are engaged in the insulating body can effectively avoid the risk of the connecting member being detached from the insulating body.

The insulative housing 10 includes two side walls 11 extending along a longitudinal direction thereof and two end walls 12 respectively connecting the ends of the two side walls 11. The two side walls 11 and the two end walls 12 are circled to receive Slot 13 of the electronic card. The direction in which the electronic card is inserted is the downward direction, and the two side walls 11 are respectively recessed downwardly with a row of terminal slots 110 for receiving the terminals 30.

Referring to the second figure, the ear button portion 20 includes a main body portion 200, a pivot shaft 201 disposed under the main body portion 200, and is disposed above the main body portion 200 and facing away from the slot. The extending portion 202 and the fastening portion 204 and the holding arm 203 are also disposed above the main body portion 200 but extending toward the slot 13 . The insulative housing 10 is provided with a pivot hole 100 at one end thereof, and the pivot hole 100 is disposed corresponding to the pivot shaft 201. When the pivot shaft 201 is assembled to the pivot hole 100, The earloop portion 20 is rotatable about the pivoting shaft 201 to perform an operation of locking and releasing the electronic card inserted into the card edge connector 1.

The terminals 30 are symmetrically arranged in two rows and received in the terminal slot 110, and include a terminal beam 300, a contact portion 302 extending upward from the terminal beam 300 and protruding into the slot 13, and the self-terminal beam 300. The solder legs 301 of the insulative housing 10 extend downward. When the docking electronic card is inserted into the card edge connector 1, the contact portion 302 is electrically connected to the electronic card, and electrical communication between the electronic card and the electronic board is achieved by soldering to the soldering leg 301 of the docking circuit board.

Referring to the second to fourth figures, the connecting member 40 is fitted into the insulative housing 10 from the top surface of the insulative housing 10, and the connecting member 40 includes a soldering portion 401 extending from the insulative housing 10. And housed inside the insulative housing 10 The retaining portion 402, the two sides of the upper portion of the retaining portion 402 extend outwardly to form a limiting portion 4021, and the two sides of the limiting portion 4021 are recessed with a recess portion 40211 to release the assembly process. The internal stress prevents the damage of the connecting member 40; the pair of elastic arms 4022 extend upward on both sides of the lower portion of the retaining portion 402, and a pair of notches are recessed inwardly corresponding to the position of the elastic arm on both sides of the retaining portion 402. 4023, the elastic arm 4022 can be gathered into the notch 4023 by an external force. The elastic arm 4022 includes a bending portion 40221 and an arm body 40222 extending upward from the bending portion 40221 in parallel with the holding portion 402. The bending portion 40221 protrudes outward from the two sides of the holding portion 402. The holding portion 402.

A recessed portion 14 is disposed in the slot 13 of the insulative housing 10 from the end wall 12a. In the embodiment, the connecting member 40 is mounted in the end wall 12a and the foolproof portion 14, in other In an embodiment, the connector 40 can also be fitted into the end walls 12.

As shown in the third figure, the foolproof portion 14 and the end wall 12a are respectively provided with a mounting hole 120, and the mounting hole 120 includes a mounting hole 120 above the mounting hole 120 and upwardly extending out of the insulating body 10. The receiving groove 1201 is disposed below the mounting hole 120 and extends downwardly through the retaining groove 1203 of the insulating body 10 and the connecting hole 1202 connecting the receiving groove 1201 and the stopping groove 1203. The receiving groove 1201 is wider than the communication hole 1202, and the receiving groove 1201 is engaged with the limiting portion 4021 of the connecting member 40 to prevent the connecting member 40 from being assembled to the foolproof portion 14 or the The end wall 12a is swayed in the width direction thereof; the holding portion 402 of the connecting member 40 between the limiting portion 4021 and the elastic arm 4022 is matched with the communication hole 1202 to further prevent the connector 40 from being assembled. After the assembly hole 120 is swayed in the width direction of the assembly hole 120; the stop groove The width of the 1203 is smaller than the width of the receiving groove 1201, and the width of the retaining groove 1203 is larger than the freely extending width of the elastic arm 4022 of the connecting member 40, so as to facilitate installation and ensure that the connecting member 40 is properly assembled. The arm 4022 can be fully opened. The bending portion 40221 of the elastic arm 4022 protrudes from the two sides of the holding portion 402 to the holding portion 402. When the elastic arm 4022 is freely extended, the arms 40222 of the two elastic arms 4022 are The distance between the openings is greater than the width of the communication hole 1202 to ensure that the elastic arm 4022 can be inverted to the upper edge of the stop groove 1203 after the connector 40 is properly mounted.

The width of the retaining groove 121, the communication hole 1202, and the retaining groove 1203 of the end wall 12a in the longitudinal direction of the insulating body 10 matches the thickness of the connecting member 40, and further restricts The connection member 40 is shaken to enhance its stability.

In the process of correctly fitting the connecting member 40 to the foolproof portion 14 or the end wall 12a, the communication hole 1202 presses the elastic arm 4022 and is gathered in the notch 4023 so that The elastic arm 4022 smoothly passes through the communication hole 1202. When the elastic arm 4022 completely passes through the communication hole 1202, the limiting portion 4021 of the connecting member 40 abuts the lower edge of the receiving groove 1201, and the elastic arm 4022 is released and snapped to the end. The upper edge of the slot 1203 is retracted to secure the connector 40 to the card edge connector 1.

When the card edge connector 1 is assembled to its mating circuit board, the soldering portion 401 of the connector 40 is soldered to the mating circuit board to fix the insulative housing 10 to the circuit board to prevent The terminal 30 is separated from the insulative body when there is shaking or shaking.
