Description

Cable connector

The present invention relates to a cable connector, and more particularly to a cable connector having an anti-missing structure.

The hard disk (HDD) connector developed under the SATA (Serial Advanced Technical Attachment; Serial ATA) system has a relatively new structure. Therefore, the current connector has many shortcomings in terms of production cost considerations. Examples are as follows:

1. Because the structure is more complicated, it is more difficult to identify its directionality. Therefore, when assembling each component, it is often impossible to install it due to an error in the assembly direction.

2. The structure of the existing HDD connector is not well designed in the assembly process, resulting in a long assembly time and a natural increase in cost.

3. When the connector is electrically connected, the stable connection is the main appeal; otherwise, when the connector is disconnected, the transmission of information is interrupted, which may cause no small loss. Therefore, the stable connection of the connector is also lacking in the current structure.

Therefore, how to design a cable connector to reduce the cost during production and to be more stable in practical applications will be an important issue for those familiar with the art.

The main purpose of this creation is to provide a cable connector to reduce the cost of production, such as preventing assembly errors when assembling components. The foolproof device, or the order of assembly of the components.
