Description

Flexible cable connector

The invention relates to a flexible cable connector, and more particularly to a rear flip-type flexible cable connector.

Because the flexible cable has the characteristics of adapting to the external environment to change its shape, it is widely used in various electronic devices as a channel for electrical signal transmission between circuit boards. The circuit board should be matched with a flexible cable, and usually a flexible cable connector is provided to electrically connect the flexible cable.

There are many types of flexible cable connectors, which can be roughly divided into three types: front clamshell type, rear clamshell type and drawer type. Among them, the former clamshell type flexible cable connectors are the most common. In the flip-type flexible cable connector, a rotatable pressing body is provided at the front or rear end of the connector body. When the pressing body rotates, the conductive terminal can be pressed, forcing the elastic arm of the conductive terminal to deform, and the electrical connection with the flexible cable inserted therein is completed.

However, in order to meet the requirements of electrical signal transmission, flexible cable connectors are usually equipped with a large number of conductive terminals. At present, even FPC connectors with dozens of conductive terminals can be seen in the industry. The contact points of many conductive terminals can be reliably contacted and conducted. The span of the pressing body must be increased. The longer the span of the pressing body, the more likely it is that the deformation of the various parts of the pressing body will be different under the condition of uneven force. The deformation of the elastic arms of the conductive terminals on the flexible cable connector is not as expected. If it is serious, it will also cause the flexible cable connector and the flexible cable. The electrical connection of the cable is abnormal.
