In addition, the second terminal of the conventional card edge connector has the following disadvantages. Since the pair of spring arms are parallel to each other, when the signal processing component is inserted into the slot and touches the abutment portion of one of the elastic arms, When the elastic arm moves away from the slot, the other elastic arm is also moved away from the slot, and the abutting portion of the other elastic arm is also moved away from the slot, so that The interlocking condition is caused. Therefore, when the conductive area of the signal processing component is uneven, if the signal processing component cannot be in contact with the abutting portion of one of the elastic arms, the abutting portion of the other elastic arm cannot be abutted. Signal Processing the conductive area of the component, thereby causing poor contact conditions, and the signal data that cannot be smoothly transmitted between the motherboard and the signal processing component.

One of the purposes of the present invention is to provide a card edge connector that abuts and electrically connects the signal processing components with the primary abutting portion and the secondary abutting portion, thereby improving the contact between the conductive terminal and the signal processing component. The effect of sexual connections.

In order to achieve the above object, the present invention provides a card edge connector including an insulating base and at least one conductive terminal; the insulating base has a slot for inserting the signal processing component; the conductive terminal is worn Connected to the insulating base, the conductive terminal comprises a supporting section, a main elastic arm and a pair of elastic arms; the main elastic arm is extended from a side of the supporting section and has a main abutting portion in the slot The secondary arm extends from the side of the support section toward the main elastic arm and is located on one side of the main elastic arm, and the secondary arm has a position in the slot and is located at the support section and the primary a pair of abutments between the joints.

In order to achieve the above object, the present invention further provides a conductive terminal of a card edge connector, comprising a support section, a main elastic arm and a pair of elastic arms; a main body of the main elastic arm extending from a side of the support section An auxiliary portion extending from a side of the support section toward the main elastic arm and located at a side of the main elastic arm, the secondary arm having a positioning portion and the main abutting portion A pair of abutments.

The present invention also has the following effects. First, since only one of the main abutting portion or the secondary abutting portion needs to abut the conductive region of the signal processing component 9, the signal can be signaled to the motherboard and the signal processing component. Passing between each other, therefore, the card edge connector can be improved In the production ratio of the yield, the efficiency of the process is saved.
