Description

[Technical Field]

[0001] The present invention relates to a dual card edge connector, and more particularly to a dual card edge connector having an integrated double-sided engagement design that can securely engage mating printed circuit boards. [Background technology]

[0002] Card edge connectors are connectors that electrically connect to printed circuit boards (PCBs) through slots and are widely used in electronic devices and computer systems. This type of connector is commonly used for memory modules, expansion cards, and other applications requiring quick connection and removal. Dual card edge connectors are a type of card edge connector. Dual card edge connectors contain two card edges within a single connector, allowing them to simultaneously connect two printed circuit boards, providing higher connection density and design flexibility. They are widely used in high-performance computing and communications equipment. As connector functions and application fields become increasingly mature and broader, the demand for card edge connectors is increasing day by day. Improving connector assembly efficiency and reducing production costs are currently among the challenges that need improvement.

[0003] 1 and 2 are schematic diagrams showing a conventional dual card edge connector and a board connected thereto. The conventional connector is composed of a housing 1, an engaging member 2, and a contact member 3. When a board is mated to the connector, the engaging member 2 provides secondary locking. As shown in the exploded view of FIG. 2, the engaging member 2 used in the conventional connector is a single locking part. Depending on the needs of the connector, at least two engaging members 2, one above the other, are required on each side, resulting in four engaging members on both the left and right sides. If multiple engaging members 2 are installed in the dual card edge connector due to combination needs, the number of assembly parts increases, which increases assembly time and production costs.

[0004] SUMMARY OF THE INVENTION In view of this, the present invention proposes a dual card edge connector that can solve the problems of the conventional dual card edge connectors, such as increased assembly time and rising assembly costs. Summary of the Invention
