Description

Technical Field

[0001] This invention relates to the field of FFC connectors, specifically to a novel FFC connector structure. Background Technology

[0002] An FFC connector is an adapter used to connect FFC (Flexible Cable) cables to traditional wire harness connectors. Due to the thinness and flexibility of FFC cables, FFC connectors are widely used in automotive electronic devices for signal and circuit transmission, thus meeting the circuit application requirements of special and complex automotive scenarios.

[0003] Currently, FFC connectors can only connect the FFC flexible wire to a single contact of the connector during use, and there is no auxiliary locking device. As a result, the FFC connection is prone to instability, poor contact or even falling off during long-term use, which in turn causes instability in circuit and signal transmission. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a novel FFC connector structure that solves the problem of poor contact and unstable signal contact during long-term use of FFC connectors.

[0005] (II) Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solution: a novel FFC connector, comprising a housing; a terminal body is inserted into the inner side of the housing, and the terminal bodies are arranged in a plurality of parallel configurations along the housing; one end of the terminal body is configured as a terminal double contact structure; a push-button is rotatably connected to one side of the top of the housing; a snap fastener is provided on the inner side of both ends of the push-button near the terminal double contact structure; and hardware is fastened on the inner side of both ends of the housing.

[0006] Preferably, the terminal body is arranged in a flat manner at the tail end away from the terminal dual-contact structure.

[0007] Preferably, the terminal body is made of metal.

[0008] (III) Beneficial Effects This invention provides a novel FFC connector structure. It offers the following advantages: By pressing multiple terminal bodies together, the terminal bodies can clamp the upper and lower dual contacts of the inserted FFC flexible flat cable, resulting in a more stable contact signal.

[0009] By setting up the interaction between the latch and the button, when the button is pressed down, the latch will lock in place and press the FFC cable tightly, thus achieving dual positioning and preventing the FFC cable from shifting during product vibration, which could lead to abnormal signal transmission.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0013] like Figure 1-9As shown, this embodiment of the invention provides a novel FFC connector, including a housing 1; a terminal body 2 is inserted into the inner side of the housing 1, and the terminal bodies 2 are arranged in a plurality of rows along the housing 1; one end of the terminal body 2 is configured as a terminal double contact structure 201; a button 4 is rotatably connected to one side of the top of the housing 1; a buckle 5 is provided on the inner side of both ends of the button 4 near the terminal double contact structure 201; and hardware 3 is fastened on the inner side of both ends of the housing 1.

[0014] In the above, the terminal double contact structure 201 contacts the inserted FFC, thereby achieving upper and lower double contact clamping contact, making the contact signal more stable.

[0015] The terminal body 2 is set in a flat manner at the end away from the terminal double contact structure 201.

[0016] In the above, by adopting a flat design for the tail of the terminal body 2, the contact area with the PCB board is larger and it is easier to form a good flatness, resulting in a more stable connection.

[0017] Terminal body 2 is made of metal.

[0018] The above uses a metal material, which allows it to conduct electricity while also having good elasticity.

[0019] Working principle: During use, open the button 4 to separate it from the housing 1, thus preventing the button 4 from squeezing the terminal body 2 and allowing the terminal double contact structure 201 to open. At this time, the prepared FFC flexible flat cable can be inserted into the terminal body 2 through the terminal double contact structure 201. After the FFC flexible flat cable is inserted, close the button 4 again. The button 4 will press the terminal body 2 tightly, bringing the terminal double contact structures 201 closer together, thus squeezing the FFC flexible flat cable and clamping the upper and lower double contacts of the FFC flexible flat cable. When the button 4 and housing 1 are closed, the buckle 5 will lock the housing 1 and press the FFC flexible flat cable, providing double locking to prevent the FFC flexible flat cable from shifting during product vibration, which could cause abnormal signal transmission. Next, solder the hardware 3 onto the PCB substrate and let the terminal body 2 fit against the substrate to complete the installation.

[0020] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
