The operation of the left hand and the operation of the right hand need to be performed at the same time. It can be seen that the existing connector is not convenient for the user to unplug the cable.

[0004] Therefore, in order to solve the above technical problems, finding a connector that is easy to operate has become an important topic studied by those skilled in the art. Summary of the invention

[0005] The embodiment of the present invention discloses a connector suitable for a flat cable, which is used to solve the technical problem that the existing connector requires the user to use both hands at the same time to pull out the flat cable, causing inconvenience to the user.

[0006] An embodiment of the present invention provides a connector suitable for flat cables, comprising a rubber core body, a terminal group accommodated in the rubber core body, a grounding member located in front of the terminal group, and an operating member located behind the terminal group;

[0007] The grounding member comprises a substrate, and first elastic arms extending along the length direction of the rubber core body are arranged on opposite sides of the substrate, the first elastic arms can rotate downward under force, and the first elastic arms are provided with hooks for fixing the cable;

[0008] The operating member includes a push-unlocking portion exposed from the rubber core body, the push-unlocking portion is located above the first elastic arm, and the push-unlocking portion can drive the first elastic arm to rotate downward so that the hook on the first elastic arm is separated from the flat cable;

[0009] The second elastic arms extending along the length direction of the rubber core body are arranged on opposite sides of the push-to-unlock part, and the second elastic arms can rotate downward under the drive of the push-to-unlock part, and a self-locking spring is arranged between the second elastic arm and the first elastic arm, and a force-bearing protrusion structure that can cooperate with the cable is arranged on the first side of the self-locking spring facing the first elastic arm, and the self-locking spring can be biased toward the second elastic arm under force, and a self-locking protrusion that cooperates with the second elastic arm is arranged on the second side of the self-locking spring facing the second elastic arm.

[0010] Optionally, the force-bearing protrusion structure is a protrusion arranged on the first side surface of the self-locking spring.

[0011] Optionally, the force-bearing protrusion structure is formed by bending the first side surface of the self-locking elastic sheet.

[0012] Optionally, the self-locking spring and the operating member are an integral structure.

[0013] Optionally, the bottom of the self-locking spring is fixed in the rubber core body.

[0014] Optionally, a side surface of the hook facing the substrate is an inclined surface that abuts against the cable;

[0015] When the flat cable is inserted into the connector, the front end of the flat cable moves along the inclined surface and drives the first elastic arm to rotate downward.

[0016] Optionally, the self-locking protrusion is a spherical protrusion.

[0017] Optionally, a terminal groove is provided inside the rubber core body, and the terminal group is arranged in the terminal groove.

[0018] Optionally, first bases are provided on opposite sides of the substrate, and one end of the first base away from the terminal group is bent 180° and extends along the length direction of the rubber core body to form the first elastic force arm.

[0020] The side surface of the push-to-unlock portion is fixedly connected to the second elastic arm.

[0021] It can be seen from the above technical solutions that the embodiments of the present invention have the following advantages:

[0022] The connector in this embodiment is more convenient for users to pull out the cable. When the cable is fully inserted into the connector, the left and right sides of the cable abut against the force-bearing protrusion structure on the self-locking spring sheet. The self-locking spring sheet is pressed toward the second elastic arm. When the user needs to pull out the cable, he only needs to press the unlocking part downward with his hand. When the unlocking part moves downward under the force, it drives the first elastic arm to rotate downward, so that the hook is separated from the cable and no longer fixes the cable. At the same time, the second elastic arm is also driven to move downward. The second elastic arm moves to the bottom of the self-locking protrusion, and the self-locking protrusion The second elastic arm is restricted from rotating upwards. At this time, the user can release the push-unlocking part and then pull out the cable. After the cable is pulled out about 10%, the self-locking springs on both sides of the cable return to their initial positions due to no pressure from the cable. The self-locking protrusion no longer restricts the second elastic arm from rotating upwards. The second elastic arm rotates upwards to return to its initial position, and the push-unlocking part returns to its initial position synchronously. After the cable is further pulled out 20%, the hook on the first elastic arm also rotates upwards to return to its initial position due to no pressure from the cable. Through the above design, the user can pull out the cable from the connector with one hand, and the connector is more convenient for users to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The embodiment of the present invention discloses a connector suitable for a flat cable, which is used to solve the technical problem that the existing connector requires the user to use both hands at the same time to pull out the flat cable, causing inconvenience to the user.

[0044] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] Embodiment 1

[0046] See also Figures 1 to 5 , Figures 8 to 18 In this embodiment, a connector suitable for a flat cable is provided, which can be suitable for an FFC flat cable 7. The front end of the FFC flat cable 7 mentioned in this embodiment is provided with a card slot 701 on both opposite sides. The structure of the connector includes:

[0047] The rubber core body 1, the terminal group 5 accommodated in the rubber core body 1, the grounding member 2 located in front of the terminal group 5 and the operating member 3 located behind the terminal group 5; Figure 1 As shown, a cavity structure matching the shape of the grounding member 2 is provided inside the rubber core body 1, and a cavity structure matching the shape of the operating member 3 is also provided inside the rubber core body 1, and the grounding member 2 and the operating member 3 are respectively provided in the corresponding cavity structures;

[0048] The grounding member 2 includes a substrate 201. The substrate 201 is provided with first elastic arms 202 extending along the length direction of the rubber core body 1 on opposite sides thereof. The first elastic arms 202 can be rotated downward under force. The first elastic arms 202 are provided with hooks 204 for fixing the flat cable 7. Specifically, the front end of the flat cable 7 is provided with grooves 701 matching the hooks 204 on opposite sides thereof. When the hooks 204 are engaged in the grooves 701, the flat cable 7 is fixed inside the connector.

[0049] The operating member 3 includes a push-unlocking portion 301 exposed on the rubber core body 1. The push-unlocking portion 301 is located above the first elastic arm 202. The push-unlocking portion 301 can drive the first elastic arm 202 to rotate downward, so that the hook 204 on the first elastic arm 202 is separated from the flat cable 7. Specifically, when the push-unlocking portion 301 moves downward under the pressure of the user, the bottom of the push-unlocking portion 301 contacts the first elastic arm 202, so that the first elastic arm 202 is pressed and rotated downward, so that the hook 204 is separated from the slot 701 on the flat cable 7.

[0050] The second elastic arms 302 extending along the length direction of the rubber core body 1 are arranged on opposite sides of the push-unlocking portion 301. The second elastic arms 302 can rotate downward under the drive of the push-unlocking portion 301. A self-locking spring 6 is arranged between the second elastic arm 302 and the first elastic arm 202. The self-locking spring 6 is arranged on the first side of the first elastic arm 202 with a force-bearing protrusion structure 601 that can cooperate with the flat cable 7 to abut. It should be noted that, if Fig.11 and Fig.12 As shown, when the cable 7 is fully inserted into the connector, the opposite sides of the front end of the cable 7 are squeezed by the force-bearing protrusion structure 601, causing the self-locking spring sheet 6 to be biased toward the second elastic arm 302. When the cable 7 is not inserted into the connector, the distance between the force-bearing protrusion structures 601 on the two self-locking spring sheets 6 should be smaller than the width of the front end of the cable 7;

[0051] A self-locking protrusion 602 cooperating with the second elastic arm 302 is provided on the second side surface of the self-locking elastic piece 6 facing the second elastic arm 302 .

[0052] It should be noted that, combined with Figure 3 , Figure 4 , Fig.18 It can be seen that the terminal set 5 is located between the two first elastic arms 202 , and the two first elastic arms 202 are located between the two second elastic arms 302 .

[0053] Furthermore, if Figure 4 As shown, the force-bearing protrusion structure 601 in this embodiment is a protrusion, and the protrusion is arranged on the first side surface of the self-locking spring piece 6;

[0054] It should be noted that if Fig.12 As shown, the protrusion is a semi-cylindrical protrusion. When the flat cable 7 is fully inserted into the connector, the opposite sides of the head end of the flat cable 7 touch each other with the protrusion. After the protrusion is pressed, the entire self-locking spring 6 rotates toward the second elastic arm 302.

[0055] Furthermore, the self-locking spring piece 6 and the operating member 3 in this embodiment are an integrated structure;

[0056] It should be noted that this method can reduce the difficulty of production. Since the self-locking spring piece 6 and the operating member 3 are an integrated structure, the manufacturer can use a set of molds to complete the production.

[0057] Furthermore, in this embodiment, a side surface of the hook 204 facing the substrate 201 is an inclined surface 2041 that cooperates with the flat cable 7 to abut against the flat cable 7;

[0058] It should be noted that, combined with Figures 8 to 10When the cable 7 is inserted into the connector, the front end of the cable 7 moves along the inclined surface 2041 and drives the first elastic arm 202 to rotate downward. When the front end of the cable 7 continues to move into the interior of the connector, the hook 204 is inserted into the groove 701 of the cable 7, so that the cable 7 is fixed inside the connector. At this time, the hook 204 on the first elastic arm 202 is not subjected to the pressure of the front end of the cable 7, and the first elastic arm 202 returns to its initial position under the action of its own elastic force.

[0059] Furthermore, combined with Figure 5 It can be seen that the self-locking protrusion 602 in this embodiment is a spherical protrusion;

[0060] It should be noted that, through the design of the spherical bump, such as Fig.14 As shown, when the flat cable 7 is fully inserted into the connector, the second elastic arm 302 rotates downward under the drive of the press unlocking portion 301, and the second elastic arm 302 moves from the surface of the spherical bump until the top surface of the second elastic arm 302 conflicts with the bottom of the spherical bump. At this time, the spherical bump will clamp the second elastic arm 302, so that it cannot rotate upward. At this time, the connector is in a self-locking state. After that, the user can pull out the flat cable 7. This embodiment does not limit the shape of the self-locking bump 602, and its specific shape can be any shape as long as it can achieve the above-mentioned self-locking effect.

[0061] Furthermore, a terminal slot 4 is disposed inside the rubber core body 1 in this embodiment, and a terminal group 5 in this embodiment is disposed in the terminal slot 4 .

[0062] Furthermore, if Figure 3 As shown, first bases 203 are disposed on opposite sides of the substrate 201 , and one end of the first base 203 away from the terminal set 5 is bent 180° and extends along the length direction of the rubber core body 1 to form a first elastic force arm.

[0063] like Figure 4 As shown, the operating member 3 has a second base 303 fixedly connected to the rubber core body 1, and one end of the second base 303 close to the substrate 201 is bent 180° and extends along the length direction of the rubber core body 1 to form a second elastic arm 302;

[0064] The side surface of the push-to-unlock portion 301 is fixedly connected to the second elastic arm 302 .

[0065] It should be noted that this embodiment does not limit the bending angles of the first base portion 203 and the second base portion 303 .

[0066] The working principle of the connector in this embodiment is described as follows:

[0067] like Fig.12As shown, when the flat cable 7 is fully inserted into the connector, the left and right sides of the flat cable 7 abut against the force-bearing protrusion structure 601 on the self-locking spring sheet 6, and the self-locking spring sheet 6 is pressed toward the second elastic arm 302, as shown in FIG. Fig.14 As shown, when the user needs to pull out the flat cable 7, he only needs to press the unlocking part 301 downward with his hand. When the unlocking part 301 is forced to move downward, it drives the first elastic arm 202 to rotate downward, so that the hook 204 is separated from the flat cable 7 and no longer fixes the flat cable 7. At the same time, the second elastic arm 302 is also driven to move downward. The second elastic arm 302 moves to the bottom of the self-locking protrusion 602. The self-locking protrusion 602 restricts the second elastic arm 302 from rotating upward. At this time, the connector is in a self-locking state ( Fig.14 (a) is a schematic diagram of the connector in a self-locking state. Fig.15 and Fig.16 As shown, the user can then release the push-unlocking portion 301 and then pull out the flat cable 7. After the flat cable 7 is pulled out about 10%, the self-locking springs 6 on both sides of the flat cable 7 are restored to their initial positions because they are not subjected to the pressure of the flat cable 7. The self-locking protrusion 602 no longer restricts the second elastic arm 302 from rotating upward. The second elastic arm 302 rotates upward to restore to its initial position, and the push-unlocking portion 301 is simultaneously restored to its initial position. Fig.17 As shown, after the flat cable 7 is further pulled out by 20%, the hook 204 on the first elastic arm 202 is no longer under the pressure of the flat cable 7, and the first elastic arm 202 also rotates upward to return to the initial position. Through the above design, the user can pull out the flat cable 7 from the connector with one hand (that is, press the unlocking part 301 with one hand and then pull the flat cable 7 out of the connector with one hand), and the connector is more convenient for users to use.

[0068] Embodiment 2

[0069] This embodiment is improved on the basis of the first embodiment. Specifically, Figure 6 As shown, the force-bearing protrusion structure 601 in this embodiment is formed by bending the first side surface of the self-locking spring piece 6 according to the shape of the cable 7, as shown in FIG. Figure 6 shown.

[0070] Embodiment 3

[0071] This embodiment is improved on the basis of the first embodiment. The self-locking spring piece 6 in the first embodiment is connected to the operating member 3 and is an integral structure with the connecting member. In this embodiment, Figure 7 As shown, the self-locking spring piece 6 and the operating member 3 are separated structures, that is, the bottom of the self-locking spring piece 6 is fixed in the rubber core body 1 instead of being connected to the operating member 3 .

[0072] The above is a detailed introduction to a connector suitable for flat cables provided by the present invention. For a person skilled in the art, according to the concept of the embodiments of the present invention, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
