2. Description of Related Art
With the rapid development of network and communication technology, the consumers' demands for the transmission speed are increasing. The electric connectors used in computers and electronic products must be able to transmit high-frequency and high-speed signals. Therefore, the connector of low voltage differential signal (LVDS) has been developed in recent years, which utilizes high-speed vibration of extremely low voltage amplitude to transmit the data. It has the advantages of low power consumption and low bit error rate.
The main structure of existing LVDS connector comprises an insulating body and a shielding housing. The insulating body has a front and a rear opening space. The flat conductor is inserted into the rear opening, and the connecting part of the flat conductor is at the front opening. In order to avoid the loosening and falling of the flat conductor (such as FPC or FFC), a notch is provided on the flat conductor, and a limiting device is affixed to the notch to stabilize the flat conductor. However, the structure of the limiting device of conventional LVDS connector is complex and the assembly method is complicated, which affects the production efficiency.
Therefore, a new technical scheme needs to be developed to address said problem.
The primary objective of the present invention is to provide an electric connector for flat conductor, where the flat conductor is inserted to push the elastic buckling piece open, and then the elastic buckling piece is automatically reset to buckle the flat conductor. The structure is simple and easy to produce, and can firmly secure the flat conductor, thereby effectively improving the production efficiency and product quality.
The second objective is to provide an electric connector for flat conductor, where a jig is used to prop the buckling part first; after the flat conductor is inserted completely, the jig is removed, and the elastic buckling piece is automatically reset to buckle the flat conductor. The structure is simple and easy to produce, and can firmly secure the flat conductor, thereby effectively improving the production efficiency and product quality.
The third objective is to provide an assembly method for electric connector and flat conductor. The assembly method is simple and easy to operate, thereby effectively improving the assembly efficiency and reducing the production cost.
To realize said purposes, the present invention adopts the following technical scheme:
An electric connector for flat conductor, comprising at least an insulating body, a guiding slot for insertion of the flat conductor is provided at the front opening of the flat conductor; on the opposite side, an inserting part is provided for insertion with the corresponding connector; on the inserting part, there is an inserting slot for connection with said guiding slot; the connecting part of the flat conductor is inserted into the guiding slot and is positioned at said inserting part to be in contact with the connector; according to the position of the two notches on the flat conductor, there is an insert slot across the guiding slot on the insulating body along a thickness direction of the flat conductor.
In the insert slot, an elastic buckling piece is formed integrally on the insulating body. Said elastic buckling piece comprises an elastic arm extending laterally on the insulating body and a buckling part protruding vertically; said buckling part protrudes into the guiding slot, after the flat conductor is inserted completely, the buckling part is buckled at the notch of the flat conductor with the rebound action of elastic arm, in order to prevent the flat conductor from falling.
As a preferred embodiment, a guiding slope is provided on said buckling part for the convenience of inserting the flat conductor. By pushing the guiding slope of the buckling part of the flat conductor, the buckling part is pushed up automatically under the elastic action of the elastic arm, allowing the flat conductor to be inserted easily. Finally, the buckling part is buckled to the notch of the flat conductor with the rebound action of elastic arm.
As a preferred embodiment, said buckling part is provided with a pressed part at the external side of flat conductor. Said pressed part is pushed by the external jig, and drives and pushes the buckling part up, thus allowing the flat conductor to be inserted. Finally, said buckling part is buckled at the notch of flat conductor with the rebound action of elastic arm.
As a preferred embodiment, said buckling part is equipped with a receding groove along the thickness direction of the flat conductor to provide flexibility for the movement of guiding part.
As a preferred embodiment, the left and right sides of said inserting part are provided with a limiting part respectively for stopping the front part of the flat conductor.
As a preferred embodiment, the front part of said insert slot is provided with an anti-warping part for stopping the front part of the flat conductor.
As a preferred embodiment, said connector comprises a shielding housing and left and right hooks.
As a preferred embodiment, said shielding housing and left and right hooks are formed integrally. Said hook comprises of the stopping part, elastic compression part and hook part. Said stopping part is connected integrally onto the shielding housing.
An electric connector for flat conductor and assembly for electric connector and flat conductor defined in claim 3, its assembly procedure is as follows:
(1) Prepare an electric connector for flat conductor, a flat conductor and a jig; said jig is provided with a pushing block;
(2) Utilize the pushing block of said jig to push the pressed part upwards in the preset procedure so that the pressed part drives and pushes the buckling part upwards under the action of the elastic arm; the flat conductor can thus pass through the pressed part by zero insertion force;
(3) Insert the flat conductor from the guiding slot, putting the connecting part at its front part on the inserting part;
(4) Release the jig and the buckling part restores back to its natural state under the rebound action of elastic arm. Then, the buckling part is extended into the guiding slot and buckled in the notch of the flat conductor.

In the natural state, the buckling part of the elastic buckling piece extends into the guiding slot where the flat conductor is located. During assembly, the flat conductor is inserted to push the elastic buckling piece open. After the flat conductor is inserted completely, the elastic buckling piece is automatically reset to buckle the flat conductor. The structure is simple and easy to produce, and can firmly secure the flat conductor, thereby effectively improving the production efficiency and product quality.
