Description

Card edge connector combination

This creation relates to a card edge connector combination.

Generally, the locking mechanism of the electronic card usually only provides an electronic card for holding a single length, and cannot be applied to an electronic card of different lengths, and it is necessary to use another locking mechanism to use the electronic card of different lengths, This has led to a lack of increased manufacturing costs. The Republic of China New Patent Publication No. M303514 discloses a card edge connector that can accommodate two electronic cards of different lengths. The locking mechanism of the card edge connector includes a pair of locking devices, which are separately fixed to the two sides of the circuit board with respect to the joint, and the two locking devices and the joint enclose a card space, and each of the locking devices extends a resilient arm having a first locking portion at a free end thereof, the first locking portion is adjacent to the connector and extending into the card space, and a second elastic arm having a second locking portion at the free end thereof, the second locking portion The buckle portion is away from the joint and extends into the card space, and the metal frame body can further form an elastic actuating member to force the first elastic arm to be pushed; thereby, the through-locking portion can be used to provide the buckle insertion Two electronic cards of the same interface but different lengths, and the actuating member can be moved outward by the first elastic arm to provide the convenience of card withdrawal.

However, the card edge connection only applies to two electronic cards of different lengths, and in the process of installing the electronic card, the closer locking device is likely to interfere with the insertion of the longer electronic card. In view of the above drawbacks, it is necessary to design a low cost card edge connector combination.

It is an object of the present invention to provide a card edge connector assembly that is simple in construction and adaptable to the insertion of multiple electronic cards of different lengths.

In order to solve the above technical problem, the technical means of the present invention is a card edge connector assembly which can be mounted on a circuit board for inserting and fixing electronic cards of different sizes, and the card edge connector combination includes a card edge connection. , slide and lock card holder. The card edge connector is provided with an abutting surface, a mating slot penetrating the mating surface, and a plurality of conductive terminals, the conductive terminal including a contact portion extending into the mating slot and a pin mounted on the circuit board. The slider is fixedly mounted on the circuit board and is opposite to and spaced apart from the mating face of the card edge connector. The lock card holder is provided with a card lock portion for fixing the above electronic card. Wherein, the lock card holder is mounted on the sliding seat and moves away from or close to the mating surface of the sliding seat relative to the card edge connector.

Compared with the prior art, the sliding seat and the locking base of the invention can realize electronic cards of different sizes, which saves internal space and reduces cost.
