Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically to a flexible flat cable connector that is easy to install and disassemble. Background Technology
[0002] A flexible flat cable connector is a type of electrical connector. It is usually fixed on a circuit board during use, and its terminals are made to conduct electricity with the circuit board. When connecting a flexible flat cable, the end of the flexible flat cable is electrically connected to the flexible flat cable connector, thereby realizing the electrical connection between the flexible flat cable and the circuit board. The flexible flat cable connector mainly includes a base, terminals, a cover, and positioning solder pads.
[0003] In a Chinese patent for a flexible flat cable connector (patent number: CN215869945U), the device includes a base, terminals, a cover, and positioning solder pads. The cover is rotatably mounted at a slot in the base. The terminals are inserted into the sockets of the base and have limiting arms. Positioning solder pads are mounted at both ends of the base, and the upper part of the positioning solder pads has notches. The notches cooperate with the corresponding sidewalls on the base to form an upward-opening U-shaped shaft groove. The cover has a connecting shaft that extends into the U-shaped shaft groove, and the outer end of the connecting shaft is connected to the cover as a whole through a connector. A limiting shaft is provided at the rear of the cover, and the limiting arm has a function that matches the limiting shaft. The device features a connecting groove and a limiting shaft coaxially arranged with the connecting round shaft. Through the design of the connecting body and the matching of the limiting shaft and the groove on the limiting arm, the device can effectively prevent the connecting round shaft from breaking, ensure reliable installation of the cover, and thus ensure the reliability of the electrical connection between the flexible flat cable connector and the flexible flat cable. However, in this device, the positioning solder pad is soldered onto the circuit board, and then the base of the flexible flat cable connector is snapped onto the positioning solder pad. The structure is too simple, and the snapping and fixing method is not reliable enough. The base is easy to fall off the positioning solder pad, which affects the firmness of the connection. If the connector is directly soldered onto the circuit board, subsequent disassembly and maintenance will be more troublesome. Utility Model Content
[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a flexible flat cable connector that is easy to install and disassemble. By setting up an installation mechanism, the connector body can be installed and disassembled simply by turning the handwheel. The installation is secure, the operation is simple, and it facilitates the maintenance of the connector body. This solves the problem in the background art where the device solders the positioning solder pad onto the circuit board and then snaps the base of the flexible flat cable connector onto the positioning solder pad. The structure is too simple, the snap-fit fixing method is not secure enough, and the base is easy to fall off the positioning solder pad, thus affecting the connection firmness.
[0005] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a flexible flat cable connector that is easy to install and disassemble, comprising: a concave base and a connector body, wherein the concave base is a hollow structure, and an installation mechanism is provided in the concave base; both sides of the connector body are provided with slots, and both ends of the installation mechanism are respectively inserted into the two slots.
[0006] The installation mechanism includes a handwheel rod rotatably inserted into the middle of the upper side wall of the concave base. The lower end of the handwheel rod extends into the concave base and is fixedly connected to a turntable. Two parallel pull rods are hinged to the two opposite side walls of the turntable. A slider is hinged to the opposite end of each of the two pull rods. A movable frame is fixedly connected to the opposite side of each of the two sliders. Two fixed plates are fixedly connected to the inner wall of the transverse section of the concave base. Two movable frames pass through the two fixed plates and are fixedly connected to two symmetrically arranged connecting rods. A return spring is fixedly connected between the slider and the fixed plate. The return spring is sleeved on the outside of the movable frame. A locking block is fixedly connected to the opposite side of each of the two connecting rods. The two locking blocks pass through the opposite side walls of the concave base and extend outward.
[0007] Preferably, welded corner pieces are fixedly connected to the four corners of the bottom of the concave base.
[0008] Preferably, an anti-collision ring is fixedly connected to the upper side wall of the concave base, and the anti-collision ring is located on the outside of the handwheel lever.
[0009] Preferably, the inner wall of the transverse section of the concave base is slidably connected to the side walls of the two sliders.
[0010] Preferably, the side wall of the fixed plate has a through hole, and the movable frame is disposed through the through hole.
[0011] Preferably, the concave base has sliding holes on both opposite sidewalls, and the two locking blocks are respectively set through the two sliding holes.
[0012] Preferably, the two end sidewalls of the connecting rod are frictionally connected to the two inner walls of the concave base.
[0013] The beneficial effects of this utility model are as follows:
[0014] In this invention, by setting up an installation mechanism, rotating the handwheel counterclockwise drives the turntable to rotate. At this time, the two pull rods can be pushed to swing and displace, and at the same time, the two sliders are pushed to move in opposite directions. At this time, the two return springs are compressed and contracted to generate elastic force. Simultaneously, the two moving frames drive the locking blocks fixed to the two connecting rods to move until the two locking blocks are retracted into the concave base. Then, the connector body can be placed inside the concave base. Then, the handwheel is released. At this time, the elastic force of the two return springs pushes the two locking blocks to reset and automatically lock into the two slots, which can realize the installation and fixation of the connector body. The fixation is reliable. When it is necessary to disassemble the connector body, simply rotate the handwheel counterclockwise. At the same time, the two locking blocks are completely separated from the slots on the connector body. At this time, the displacement of the connector body is no longer restricted, and the connector body can be removed. Installation and disassembly are simple and convenient for subsequent maintenance of the connector body. Attached Figure Description

[0022] like Figures 1 to 4 As shown, this embodiment provides a flexible flat cable connector that is easy to install and disassemble, including: a concave base 1 and a connector body 2. The concave base 1 has a hollow structure and an installation mechanism is provided in the concave base 1. The two side walls of the connector body 2 are provided with slots 4. The two ends of the installation mechanism are respectively inserted into the two slots 4. The bottom four corners of the concave base 1 are fixedly connected with welding corner pieces 3 for welding the concave base 1 onto the circuit board.
[0023] The mounting mechanism includes a handwheel rod 5 rotatably inserted into the middle of the upper side wall of the concave base 1. An anti-collision ring 14 is fixedly connected to the upper side wall of the concave base 1, located outside the handwheel rod 5 to prevent accidental contact. The lower end of the handwheel rod 5 extends into the concave base 1 and is fixedly connected to a turntable 6. Two parallel pull rods 7 are hinged to the two opposite side walls of the turntable 6. A slider 8 is hinged to the opposite end of each pull rod 7. The inner wall of the transverse section of the concave base 1 is slidably connected to the two side walls of the sliders 8, facilitating slider 8 displacement. A movable frame 9 is fixedly connected to the opposite side of each slider 8. Two fixed plates 10 are fixedly connected to the inner wall of the transverse section of the concave base 1. The two movable frames 9 respectively penetrate... Two fixed plates 10 are connected to two symmetrically arranged connecting rods 11. The side walls of the fixed plates 10 have through holes, through which the movable frame 9 passes to facilitate its displacement. The side walls at both ends of the connecting rods 11 are rubbed against the inner walls of the concave base 1 to stabilize the displacement of the connecting rods 11. A return spring 12 is fixedly connected between the slider 8 and the fixed plates 10. The return spring 12 is sleeved on the outside of the movable frame 9. Each of the two connecting rods 11 has a locking block 13 fixedly connected to one of their opposite sides. The two locking blocks 13 pass through the opposite side walls of the concave base 1 and extend outward. Each of the opposite side walls of the concave base 1 has a sliding hole, through which the two locking blocks 13 pass to facilitate their displacement.
[0024] The principle of this embodiment is as follows: When the connector body 2 needs to be installed on the circuit board, firstly, the concave base 1 is placed at the installation position on the circuit board, and the concave base 1 is soldered and fixed to the circuit board using the soldering corner pieces 3. Then, the handwheel lever 5 is rotated counterclockwise, causing the turntable 6 to rotate. At this time, the two pull rods 7 can be pushed to swing and move, and at the same time, the two sliders 8 are pushed to move in opposite directions. At this time, the two return springs 12 are compressed and contracted to generate elastic force. Simultaneously, the two moving frames 9 drive the locking blocks 13 fixed to the two connecting rods 11 to move until both locking blocks 13 are retracted into the concave base 1. Then, the connector body 2 can be placed inside the concave base 1. Then, the handwheel lever 5 is released. At this time, the elastic force of the two return springs 12 pushes the two locking blocks 13 to reset and automatically lock into the two slots 4, which can realize the installation and fixation of the connector body 2. The fixation is reliable. When it is necessary to disassemble the connector body 2, simply turn the handwheel lever 5 counterclockwise. At the same time, the two locking blocks 13 are completely separated from the slots 4 on the connector body 2. At this time, the displacement of the connector body 2 is no longer restricted, and the connector body 2 can be removed. The installation and disassembly are simple and convenient for subsequent maintenance of the connector body 2.
