Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a novel flexible flat cable connector. Background Technology

[0002] Flexible flat cables are used as data transmission cables between moving parts and the motherboard, or between PCBs. They allow for arbitrary selection of the number and spacing of wires, making wiring more convenient, greatly reducing the size of electronic products, reducing production costs, and improving production efficiency. They are best suited for data transmission between moving parts and the motherboard, between PCBs, and in miniaturized electrical equipment. Flexible flat cables need to be connected and installed using flexible flat cable connectors, which are generally soldered and fixed to the circuit board.

[0003] In a Chinese patent for a flexible flat cable connector (patent number: CN222673508U), the device includes a housing and a connector. The connector is fixedly connected to the back of the housing and has a back-open structure. Several retaining points are fixedly connected to the top and bottom surfaces of the connector's inner side. The retaining points have an arc-shaped structure. A positioning post is fixedly connected to the bottom of the housing, and the bottom end of the positioning post is conical. The device is configured through the cooperation of retaining points, positioning posts, elastic blocks, tracks, sliders, and limiting sleeves. Several retaining points with an arc-shaped structure are fixedly connected to the top and bottom surfaces of the connector's inner side. The retaining point is elastic and can clamp and fix the FPC from above and below to prevent it from moving or falling off during the connection process, ensuring contact. The connector is open, and with the retaining point design, it is very convenient to insert or remove the FPC / FFC cable. It can be directly plugged in and unplugged without any extra operations. However, the device only uses two-lobed elastic blocks to lock the flexible flat cable connector into the predetermined hole on the circuit board. The installation and fixation are not secure enough, and the flexible flat cable connector is easy to fall off the circuit board, affecting its functionality. At the same time, the ease of installation and removal of the flexible flat cable connector should also be considered. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a novel flexible flat cable connector. By incorporating a fixing block, rotating cylinder, rotating rod, long strip baffle, locking groove, and locking mechanism, the connector body can be installed and disassembled simply by pressing and rotating the handwheel block. This provides a simple, secure, and convenient installation and disassembly mechanism. It also solves the problem of the prior art where the device only uses a two-part elastic locking block to secure the flexible flat cable connector to a predetermined hole on the circuit board, resulting in insufficient security and easy detachment of the connector, affecting its functionality. Furthermore, the present invention also addresses the issue of easy installation and disassembly of the flexible flat cable connector.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a novel flexible flat cable connector, comprising: a connector body, both ends of which are fixedly connected to a fixing block, the fixing block having a hollow structure, a rotating cylinder inserted into and rotatably connected to the upper side wall of the fixing block, a locking mechanism provided in the rotating cylinder, four equally spaced locking grooves arranged around the rotating cylinder on the inner top wall of the fixing block, both ends of the locking mechanism being inserted into their corresponding two locking grooves, a rotating rod fixedly connected to the lower end of the rotating cylinder, the lower end of the rotating rod extending downward through the bottom wall of the fixing block and fixedly connected to a long strip baffle;

[0006] The locking mechanism includes a slider that is slidably disposed on the inner wall of the rotating cylinder. A pivot pin is fixedly connected to the upper end of the slider. The upper end of the pivot pin passes through the upper side wall of the rotating cylinder and extends outward. A compression spring is fixedly connected between the lower side wall of the slider and the inner bottom wall of the rotating cylinder. Two symmetrically arranged connecting rods are fixedly connected to both sides of the slider. A slot is opened on both sides of the rotating cylinder. The two connecting rods pass through the two slots and are fixedly connected to lock heads. The upper ends of the two lock heads are respectively inserted into their corresponding two lock slots.

[0007] Preferably, the upper side wall of the rotating drum is provided with a sliding hole, and the rotating pin is disposed through the sliding hole.

[0008] Preferably, a handwheel block is fixedly connected to the upper end of the pivot pin located on the outside of the rotating drum.

[0009] Preferably, the inner walls on both sides of the slot are frictionally connected to the side walls on both sides of the connecting rod.

[0010] Preferably, the bottom wall of the fixing block has a through hole, the rotating rod passes through the through hole, and the through hole is rotatably connected to the outer wall of the rotating rod through a bearing component.

[0011] Preferably, two symmetrically arranged positioning posts are fixedly connected to both ends of the bottom of the connector body.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, by setting a fixing block, a rotating cylinder, a rotating rod, long strip baffles, locking slots, and a locking mechanism, when it is necessary to install the connector body on the circuit board, the two long strip baffles are placed in accordance with the sockets on the circuit board, passing through the two sockets until they reach the bottom of the circuit board. Then, the handwheel block is pressed, causing the slider fixed to the rotating pin to move down in the rotating cylinder. At this time, the compression spring is compressed and generates elastic force, which simultaneously causes the two locking heads fixed to the two connecting rods to move down until the two locking heads are completely separated from the two locking slots. At this time, the rotation of the rotating cylinder is no longer restricted, and the handwheel block can be rotated to drive the rotating cylinder to rotate, which in turn drives the long strip baffles fixed to the rotating rod to rotate. The rotation is 100 degrees. At this time, the displacement of the long strip baffles is restricted by the circuit board, thus realizing the installation and fixation of the connector body to the circuit board. After rotation, the handwheel block is released. At this time, the elastic force of the compression spring pushes the two locking heads to automatically insert into the corresponding two locking slots, which can lock the rotation of the rotating cylinder. The operation is simple, the fixation is reliable, and the disassembly is also convenient. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this embodiment provides a novel flexible flat cable connector, including: a connector body 1, with fixing blocks 2 fixedly connected to both ends of the connector body 1. The fixing blocks 2 are hollow structures. A rotating cylinder 3 is inserted into and rotatably connected to the upper side wall of the fixing blocks 2. A locking mechanism is provided in the rotating cylinder 3. Four equally spaced locking slots 4 are formed around the inner top wall of the fixing blocks 2 with the rotating cylinder 3 as the center. The two ends of the locking mechanism are respectively inserted into two corresponding locking slots 4. A rotating rod 5 is fixedly connected to the lower end of the rotating cylinder 3. The lower end of the rotating rod 5 extends downward through the bottom wall of the fixing blocks 2 and is fixedly connected to a long strip baffle 6. A corresponding long strip baffle 6 is reserved on the circuit board. Prepare the sockets that match their shape. Note that when the long strip baffle 6 rotates, the upper side wall of the long strip baffle 6 abuts against the bottom wall of the circuit board. When it is necessary to fix the connector body 1 on the circuit board, adjust the direction of the two long strip baffles 6 to correspond to the sockets on the circuit board, and pass the two long strip baffles 6 through the two sockets until they reach the bottom of the circuit board. Then, rotate the rotating cylinder 3, which can drive the long strip baffle 6 fixed to the rotating rod 5 to rotate. Rotate 90°. At this time, the displacement of the long strip baffle 6 is restricted by the circuit board, which can realize the installation and fixation of the connector body 1 to the circuit board. The operation is simple, the fixation is more stable, and the disassembly is also convenient.

[0022] The locking mechanism includes a slider 7 slidably mounted on the inner wall of the rotating cylinder 3. A pivot pin 8 is fixedly connected to the upper end of the slider 7. The upper end of the pivot pin 8 passes through the upper side wall of the rotating cylinder 3 and extends outward. A compression spring 9 is fixedly connected between the lower side wall of the slider 7 and the inner bottom wall of the rotating cylinder 3. Two symmetrically arranged connecting rods 10 are fixedly connected to both sides of the slider 7. A slot 11 is opened on both sides of the rotating cylinder 3. The two connecting rods 10 pass through the two slots 11 and are fixedly connected to lock heads 12. The upper ends of the two lock heads 12 are respectively inserted into their corresponding two locking slots 4. When it is necessary to rotate the rotating cylinder 3, firstly, press the hand... The wheel block 13 drives the slider 7, which is fixed to the pivot pin 8, to move downward in the rotating drum 3. At this time, the compression spring 9 is compressed and contracts to generate elastic force. Simultaneously, it drives the two locking heads 12, which are fixed to the two connecting rods 10, to move downward until the two locking heads 12 are completely separated from the two locking grooves 4. At this time, the rotation of the rotating drum 3 is no longer restricted, and the handwheel block 13 can be turned to drive the rotating drum 3 to rotate. After the rotation is complete, the handwheel block 13 is released. At this time, the elastic force of the compression spring 9 pushes the two locking heads 12 to automatically insert into the corresponding two locking grooves 4, which can lock the rotation of the rotating drum 3. The operation is simple and the fixation is reliable.

[0023] The upper side wall of the rotating drum 3 is provided with a sliding hole, through which the rotating pin 8 is set, so that the rotating pin 8 can move up and down without affecting its rotation.

[0024] A handwheel block 13 is fixedly connected to the upper end of the pivot pin 8 located on the outside of the rotating drum 3, which facilitates the rotation of the pivot pin 8.

[0025] The inner walls on both sides of the slot 11 are frictionally connected to the side walls on both sides of the connecting rod 10, making the vertical displacement of the connecting rod 10 stable.

[0026] The bottom wall of the fixed block 2 has a through hole, through which the rotating rod 5 passes. The through hole is rotatably connected to the outer wall of the rotating rod 5 via a bearing, which facilitates the rotation of the rotating rod 5.

[0027] Two symmetrically arranged positioning posts 14 are fixedly connected to the bottom ends of the connector body 1. Positioning holes are reserved on the circuit board at the positions corresponding to the positioning posts 14 to facilitate precise positioning and installation of the connector body 1.

[0028] The principle of this embodiment is as follows: When the connector body 1 needs to be installed on the circuit board, the two long strips 6 are placed corresponding to the sockets on the circuit board. The two long strips 6 are passed through the two sockets until they reach the bottom of the circuit board. Then, the handwheel block 13 is pressed, which drives the slider 7 fixed to the pivot pin 8 to move down in the rotating drum 3. At this time, the compression spring 9 is compressed and generates elastic force. At the same time, it drives the two locking heads 12 fixed to the two connecting rods 10 to move down until the two locking heads 12 are completely separated from the two locking grooves 4. At this time, the rotating drum 3... Once rotation is unrestricted, the handwheel block 13 can be turned to drive the rotating drum 3 to rotate, which in turn drives the long strip baffle 6 fixed to the rotating rod 5 to rotate. A 90° rotation is sufficient. At this time, the displacement of the long strip baffle 6 is restricted by the circuit board, which can realize the installation and fixation of the connector body 1 and the circuit board. After rotation, the handwheel block 13 is released. At this time, the elastic force of the compression spring 9 is used to push the two locking heads 12 to automatically insert into the corresponding two locking slots 4, which can lock the rotation of the rotating drum 3. The operation is simple, the fixation is reliable, and the disassembly is also convenient.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
