Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a cover-free FPC connector. Background Art

[0002] The FPC connector is an electrical connector used to connect circuit boards and FPC cables. It is used to achieve connections between mechanical and electrical components. FPC connectors are widely used in electronic devices such as LCD displays, scanners, computers, audio, and digital devices. The FPC connector is usually provided with a flap. Before the FPC cable is connected to the FPC connector, the flap is in an open position. After the FPC cable is connected to the FPC connector, the flap is flipped to the pressing position to crimp the FPC cable to prevent the FPC cable from loosening. Existing FPC connector manufacturers mostly have the flap in the pressing position when their products leave the factory. When customers use them, they must first open the flap to the open position before connecting the FPC cable, and then insert the FPC cable into the socket and flip the flap to the pressing position. This is inconvenient for customers to use, reduces customer work efficiency, and gives customers a poor user experience. Utility Model Content

[0003] In view of this, the utility model provides a cover-free FPC connector which is convenient for customers to use.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model provides a cover-free FPC connector, comprising a base, a terminal, a welding piece and a flip cover;

[0006] The front part of the base is provided with a socket for inserting the FPC cable, the front end and the upper end of the socket are open, the terminals are arranged on the base at intervals along the left and right directions, two welding pieces are fixed at the left and right ends of the base, the flip cover is arranged on the upper part of the base and can rotate between a pressing position and an open position relative to the base, and the flip cover is suitable for crimping the FPC cable when it is in the pressing position;

[0007] It also includes a limiting structure, and the flip cover is limited by the limiting structure when it is in the open position to prevent the flip cover from rotating to the pressed position when no external force is applied.

[0008] In some embodiments, the flip cover is configured to rotate backward relative to the base from the open position to the closed position;

[0009] When the flip cover is in the open position, it is erected or tilted upwards, and when the flip cover is in the pressed position, it covers the base.

[0010] In some embodiments, connecting shafts are provided at the left and right ends of the flip cover, an axis groove is formed between the welding piece and the base, and the connecting shaft is limited in the axis groove to form a pivot structure.

[0011] In some embodiments, the limiting structure includes a support platform provided on the welding plate or the base, limiting blocks provided on the left and right ends of the flip cover, and a stop platform provided on the side wall of the socket of the base. When the flip cover is in the open position, the support platform forms an upward support for the flip cover, and the stop platform forms a downward resistance interference on the limiting block to limit the rotation of the flip cover toward the pressing position. When the flip cover is rotated from the open position to the pressing position by external force, the limiting block slides over the stop platform.

[0012] In some embodiments, a card slot is provided at the upper portion of the rear end of the base, and a buckle is provided on the flip cover at a position corresponding to the card slot, and the buckle is engaged with the card slot when the flip cover is in the pressed position.

[0013] In some embodiments, a pressure strip extending in the left-right direction is provided on the flip cover. When the flip cover is in the pressed position, the pressure strip faces downward and is suitable for crimping the FPC cable through the pressure strip.

[0014] In some embodiments, the terminal has a contact arm extending into the bottom of the socket, a snap-fit ​​arm extending into the upper part of the socket, and a solder foot extending from the base, the contact arm has an upwardly protruding contact bump, and the flip cover is provided with a snap-fit ​​portion that snaps into the snap-fit ​​arm.

[0015] In some embodiments, two or three contact protrusions are disposed on the contact arm.

[0016] In some embodiments, upwardly protruding positioning blocks are provided at the left and right ends of the socket, and the positioning blocks are used to cooperate with the positioning grooves on the edges of the FPC cable.

[0017] The structure of the FPC connector without a flip cover is optimized and designed. In this way, the flip cover is kept in the open position through the limit structure during the assembly and production of the FPC connector, so that the flip cover is prevented from easily rotating to the pressing position. Therefore, when the customer uses it on site, there is no need to open the flip cover. The FPC cable can be directly inserted into the socket and the flip cover can be turned over and pressed together, which improves the convenience of on-site installation and use by the customer and improves the customer's usage experience.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present utility model are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In the present utility model, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0037] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] The structure of the FPC connector without cover in the embodiment of the utility model is as follows Figures 1 to 9 As shown, it includes a base 1, a terminal 2, a welding piece 3 and a flip cover 4; the base 1 and the flip cover 4 are made of plastic, the terminal 2 and the welding piece 3 are made of metal, the front part of the base 1 is provided with a socket 10 for inserting the FPC cable 5, the front end and the upper end of the socket 10 are open, the terminal 2 is arranged on the base 1 at intervals along the left and right directions, two welding pieces 3 are fixed at the left and right ends of the base 1, the flip cover 4 is arranged on the upper part of the base 1 and can be rotated between a pressing position and an open position relative to the base 1, the flip cover 4 is suitable for pressing on the FPC cable 5 when in the pressing position, the terminal 2 and the welding piece 3 are welded to the circuit board 6 to achieve fixation and electrical connection during installation and use, when connecting the external FPC cable, when the flip cover 4 is in the open position, the FPC cable is inserted into the socket 10, and then the flip cover 4 is flipped to the pressing position to ensure that the gold finger on the FPC cable contacts the terminal 2, thereby realizing the electrical connection between the FPC cable and the circuit board 6.

[0039] As an optimization, the FPC connector in this embodiment is also provided with a limiting structure, and the flap 4 is limited by the limiting structure when it is in the open position to prevent the flap 4 from rotating to the pressed position when not subject to external force; in this way, the flap 4 is kept in the open position by the limiting structure during the assembly and production of the FPC connector, and the flap 4 is prevented from easily rotating to the pressed position. Therefore, when the customer uses it on site, the action of lifting the flap 4 is omitted, and the FPC cable can be directly inserted into the socket 10 and then the flap 4 can be flipped over and pressed, thereby improving the convenience of on-site installation and use by the customer and improving the customer's usage experience.

[0040] In this type of existing FPC connector, the flip cover 4 is usually rotated forward from the open position relative to the base 1 to the pressed position. In actual use, when the FPC cable 5 is pulled, the flip cover 4 will transfer force to the front edge of the flip cover 4, which will easily cause the flip cover 4 to flip backward and be pulled open. In this way, the FPC cable will be separated from the FPC connector after losing the pressing of the flip cover 4, causing the circuit to be disconnected. Therefore, in order to solve this problem, in this embodiment, the flip cover 4 is configured to rotate backward from the open position relative to the base 1 to the pressed position; when the flip cover 4 is in the open position, it is erected or tilted upward, and when the flip cover 4 is in the pressed position, it covers the top of the base 1, so that the flip cover 4 can be locked well, and the FPC cable will not have the problem of opening the flip cover 4 when it is pulled by external force.

[0041] In some embodiments, see Figure 2 and Figure 7 As shown, the left and right ends of the flip cover 4 are provided with connecting shafts 41, and an axis groove 11 is formed between the welding piece 3 and the base 1. The connecting shaft 41 is limited in the axis groove 11 to form a pivot structure, so that the flip cover 4 can be installed quickly and effectively.

[0042] In some embodiments, Figure 2 and Figure 5 As shown, the limiting structure includes a support platform 31 provided on the welding piece 3, a limiting block 42 provided on the left and right ends of the flip cover 4, and a stopper 12 provided on the side wall of the socket 10 of the base 1. When the flip cover 4 is in the open position, the support platform 31 forms an upward support for the flip cover 4, and the stopper 12 forms a downward resistance interference with the limiting block 42 to limit the flip cover 4 from rotating in the direction of the pressing position, so as to achieve the limiting effect on the flip cover 4. When the flip cover 4 needs to be rotated to the pressing position, a backward pressure is applied to the flip cover 4, and the flip cover 4 is rotated from the open position to the pressing position by an external force. In this process, the limiting block 42 slides over the stopping platform 12. As a modified implementation scheme, the support platform 31 can also be integrally provided on the base 1 in actual operation.

[0043] In some embodiments, Figure 6As shown, a card slot 13 is provided at the upper rear end of the base 1, and a buckle 43 is provided on the flip cover 4 at a position corresponding to the card slot 13. When the flip cover 4 is in the pressed position, the buckle 43 is engaged with the card slot 13, thereby locking the flip cover 4 in the pressed position to prevent the flip cover 4 from opening accidentally.

[0044] In order to ensure effective contact between the FPC cable and the terminal 2, a pressure strip 44 extending in the left-right direction is provided on the flip cover 4. When the flip cover 4 is in the pressed position, the pressure strip 44 faces downward and is suitable for pressing the FPC cable 5 inserted into the socket 10 downward through the pressure strip 44, thereby ensuring effective contact between the gold fingers on the FPC cable and the contact arms on the terminal 2, thereby ensuring the reliability of the electrical connection.

[0045] In some embodiments, Figure 3 As shown, the terminal 2 has a contact arm 21 extending into the bottom of the socket 10, a snap-fit ​​arm 22 extending into the upper part of the socket 10 and a solder foot 23 extending from the base 1, the solder foot 23 is used for soldering with the circuit board 6, the contact arm 21 has an upwardly protruding contact bump 211, and the flip cover 4 is provided with a snap-fit ​​portion 45 snapped with the snap-fit ​​arm 22. The snap-fit ​​arm 22 cooperates with the snap-fit ​​portion 45 to enhance the limiting effect on the flip cover 4, thereby ensuring the reliability and stability of the installation of the flip cover 4. When in use, after the FPC cable is inserted into the socket 10, the contact bump 211 contacts the gold finger of the FPC cable to achieve electrical connection.

[0046] In order to increase the reliable contact between the contact arm 31 and the FPC cable, Figure 4 As shown, in this embodiment, three contact protrusions 211 are provided on the contact arm 21 . In actual operation, two contact protrusions 211 may also be provided on the contact arm 21 .

[0047] In order to effectively limit the FPC cable and prevent it from loosening, in this embodiment, upwardly protruding positioning blocks 14 are provided at the left and right ends of the socket 10. The positioning blocks 14 are used to cooperate with the positioning grooves 51 on the edges of the FPC cable 5. After the FPC cable 5 is inserted into the socket 10, the positioning blocks 14 are snapped into the positioning grooves 51, thereby enhancing the reliability of the connection between the FPC cable 5 and the FPC connector.

[0048] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
