Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to an easily connectable flexible flat cable. Background Art

[0002] As a multi-core cable, flat cable was first used in electronic computers and electronic instruments. Due to its advantages such as easy bending and small wiring space, it is also widely used in household appliances such as telephones and recorders. The molding method of flat cable is to sandwich a group of core wires evenly arranged at a certain distance between two pieces of plastic film, and bond the three together into a flat cable through certain means.

[0003] Currently, flat cables have a fixed length. Flat cables used in different devices need to be customized to the required length, which means that cables of different lengths need to be produced or cut, and then the cables and connectors need to be connected. This makes it difficult to meet the needs of various scenarios. Therefore, we propose an easy-to-connect flexible flat cable that can be connected more freely and adjust the length of the flat cable to adapt to the use of different devices and scenarios. Summary of the invention

[0004] The invention provides an easily connectable flexible flat cable, which solves the problem of the flat cable having a fixed length and poor adaptability in the prior art.

[0016] The card joint is spherical, a contraction groove is provided inside the connecting seat, the card joint is arranged inside the contraction groove through a compression spring and a telescopic rod, and a card groove matching the card joint is provided on the connecting head.

[0017] In order to improve the smoothness of the plug entering the socket, a plurality of balls are rotatably arranged on the outside of the plug, and the balls are in contact with the inner wall of the socket.

[0018] To facilitate connection and removal of the plug and socket, rollers are rotatably arranged at the top and bottom of one end of the plug away from the cable unit. The rollers are flush with the end faces of the plug and contact the inner wall of the socket.

[0019] In order to improve the stability of the connection between the plug and the socket, a magnet is arranged on the side of the plug away from the cable unit, and an iron plate is arranged on the inner wall of the socket, and the magnet is in contact with the iron plate.

[0020] In order to assist the plug and the socket to be separated, a disassembly auxiliary part is provided inside the socket, and the disassembly auxiliary part includes:

[0048] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] like Figures 1 to 11As shown, this embodiment proposes an easily connectable flexible flat cable, including a cable unit, the cable unit including a conductor 101, an insulating layer 102, an armor layer 103 and a sheath 104, the insulating layer 102 is sleeved on the outside of the conductor 101 to isolate and protect the conductor 101, the armor layer 103 is sleeved on the outside of the insulating layer 102 to improve the strength of the conductor 101 and the insulating layer 102, to ensure the strength of the flat cable, a spring-shaped protective metal wire 105 is arranged on the outside of the armor layer 103, and the spring-shaped protective metal wire 105 is equivalent to another layer of armor layer 103, which further protects the conductor 101 while ensuring the flexibility and resilience of the cable, so that the flat cable can be restored to its original shape after free bending, the conductor 101 is provided with multiple strands, and the corresponding insulating layer 102, the armor layer 103 and the spring-shaped protective metal wire 105 also have multiple strands, the sheath 104 is wrapped around the outside of the multi-strand conductor 101, and is flat, and also includes a connector.

[0050] like Figures 1 to 7 As shown, the connector is used to connect two sections of cable units. The connector includes a socket 201, a plug 202, a connecting seat 203, a connecting head 204 and a locking assembly. The socket 201 is arranged at one end of the cable unit, and the plug 202 is arranged at the other end of the cable unit. The plug 202 and the socket 201 are plugged together. In order to improve the smoothness of the plug 202 entering the socket 201, a plurality of balls 1 are arranged on the outer rotation of the plug 202, and the balls 1 are in contact with the inner wall of the socket 201. The connecting seat 203 is arranged inside the plug 202, and the connecting seat 203 is electrically connected to the conductor 101. The connecting head 204 is arranged inside the socket 201, and the connecting head 204 is electrically connected to the conductor 101. The connecting head 204 and the connecting seat 203 are plugged together. A connecting groove matching the connecting head 204 is provided on the connecting seat 203, and a chamfer is provided at the edge of the connecting groove to facilitate the insertion of the connecting head 204. The two ends of the cable unit are respectively connected to the socket 201 and the plug 202. The plug 202 is inserted into the inside of the socket 201, and the connector 204 is inserted into the inside of the connecting seat 203, so that the corresponding conductors 101 in the two cable units can be electrically connected, thereby splicing the two cable units and adjusting the length of the flat cable to adapt to the use in different scenarios. The connection between the flat cable and the device can also use the plug 202 and the socket 201 connection method. The plug 202 is directly inserted into the inside of the socket 201, and the connection is more convenient. There is a certain gap between the plug 202 and the socket 201 to reduce the friction resistance between the plug 202 and the socket 201. The ball 1 contacts the inner wall of the socket 201, and the plug 202 can be limited by the ball 1. At the same time, the rotation can reduce the resistance to insertion and extraction of the plug 202. A sealing ring is provided on the outside of the plug 202, and the sealing ring contacts the end of the socket 201 to seal the socket 201 to prevent water vapor or impurities from entering the connector 204 and the connecting seat 203 to cause short circuit or electrical connection.

[0051] like Figures 1 to 11 As shown, the locking assembly is used to lock the plug 202 and the socket 201. The locking assembly includes a clamping plate 301 and a clamping block 302. Two clamping plates 301 are provided. The two clamping plates 301 are rotatably arranged on both sides of the socket 201 respectively. A return spring 303 is arranged between one end of the clamping plate 301 and the socket 201. The clamping block 302 is wedge-shaped. The clamping block 302 is arranged on a side of the clamping plate 301 away from the return spring 303. The clamping block 302 contacts the plug 202 and is used to restrict the plug 202 inside the socket 201. The clamping plate 301 is bent. The middle position of the clamping plate 301 is rotatably arranged outside the socket 201 through the rotating shaft. Under the action of the reset spring 303, the side of the clamping plate 301 away from the block 302 is away from the socket 201, and the side of the clamping plate 301 close to the block 302 is close to the plug 202. A limited position frame is arranged outside the plug 202. The narrower end of the block 302 is away from the socket 201, and the wider end is close to the socket 201. When no external force is applied, the block 302 is located at the inner position of the edge of the plug 202. When the plug 202 approaches the socket 201 , the plug 202 pushes the block 302 open, and the reset spring 303 contracts. When the plug 202 is inserted into the socket 201, the wider end of the block 302 just contacts the limit frame, limiting the limit frame to prevent the plug 202 from falling off from the inside of the socket 201. In order to improve the stability of the clamping plate 301 and the block 302 and ensure the locking effect of the block 302 on the plug 202, a baffle 304 is slidably provided on the socket 201. When the plug 202 is inserted into the socket 201, the block 302 contacts the plug 202, and the baffle 304 and the clamping plate The plate 301 contacts one side connected to the return spring 303, and the baffle 304 blocks the clamping plate 301 to prevent the clamping plate 301 from rotating, thereby ensuring the stability of the block 302. When the plug 202 needs to be pulled out from the inside of the socket 201, the baffle 304 is slid to a position away from the clamping plate 301, and the clamping plate 301 is pressed. The side of the clamping plate 301 away from the block 302 rotates inward, and the block 302 rotates outward away from the plug 202, thereby releasing the limit on the plug 202, and the plug 202 can be pulled out from the inside of the socket 201.

[0052] like Figures 5 to 7 as well as Fig.11As shown, in order to ensure the connection stability between the connector 204 and the connector base 203, a snap-in component is provided on the connector base 203, and the snap-in component includes a snap-in connector 401. The snap-in connector 401 is spherical, and a contraction groove is provided inside the connector base 203. The snap-in connector 401 is arranged inside the contraction groove through a compression spring 402 and a telescopic rod. A snap-in groove matching the snap-in connector 401 is provided on the connector 204. When the plug 202 is inserted into the socket 201, the connector 204 is inserted into the connector base 203. When the connector 204 enters the connector base 203, the connector 204 presses the snap-in connector 401 into the contraction groove. After the plug 202 is inserted into the socket 201, the connector 204 is inserted into the connector base 203, and the snap-in connector 401 is just at the snap-in groove. Under the action of the compression spring 402, the snap-in connector 401 is snapped into the slot, thereby improving the connection stability between the connector 204 and the connector base 203.

[0053] like Figures 5 to 7 As shown, in order to facilitate the connection and disassembly of the plug 202 and the socket 201, rollers 2 are rotatably provided at the top and bottom of the end of the plug 202 away from the cable unit, the end faces of the rollers 2 and the plug 202 are flush, the rollers 2 are in contact with the inner wall of the socket 201, and when the plug 202 is inserted into the socket 201, the rollers 2 first contact the edge of the socket 201, and the side of the rollers 2 close to the socket 201 is arc-shaped, and the socket 201 limits and positions the two rollers 2 so that the positions of the plug 202 and the socket 201 correspond, and at the same time, the rotation of the rollers 2 facilitates reducing the resistance of the plug 202 inserted into the socket 201.

[0054] like Figure 5 , Figure 8 and Fig.10 As shown, in order to improve the stability of the connection between the plug 202 and the socket 201, a magnet 3 is provided on the side of the plug 202 away from the cable unit, and an iron plate 4 is provided on the inner wall of the socket 201, and the magnet 3 is in contact with the iron plate 4. When the plug 202 is inserted into the socket 201, the roller 2 is in contact with the inner wall of the socket 201, and the magnet 3 is in contact with the iron plate 4, so that the plug 202 is limited. At the same time, the magnet 3 and the iron plate 4 attract each other, thereby improving the stability of the connection between the plug 202 and the socket 201.

[0055] like Figure 5 , Figure 8 and Fig.10As shown, in order to assist the plug 202 to be detached from the socket 201, a disassembly auxiliary part is arranged inside the socket 201, and the disassembly auxiliary part includes a push plate 501, which is arranged inside the socket 201 through a compression spring 502 and a telescopic rod. The push plate 501 contacts the end of the plug 202 away from the cable unit. When the plug 202 is inserted into the socket 201, the push plate 501 is pushed toward the inner wall of the socket 201 to compress the compression spring 502. The compression spring 502 has a The elastic potential energy of the plug 202 is pushed outward, and the plug 202 is pressed against the surface of the block 302 under the elastic action of the compression spring 502, thereby improving the locking effect of the block 302 on the plug 202. At the same time, when the plug 202 is disassembled, the clamping plate 301 is pressed to make the block 302 move away from the plug 202. Under the elastic force of the compression spring 502, the plug 202 is pushed out a certain distance through the push plate 501, so that the plug 202 can be easily detached from the inside of the socket 201.

[0056] like Figure 1 to Figure 2 As shown, in order to improve the strength of the flat cable connection, a gripping block 5 is provided on one side of the plug 202 and the socket 201 close to the cable unit. The cable unit is located inside the gripping block 5. When connecting or disassembling the two cable units, the gripping block 5 is gripped. The gripping block 5, the plug 202 and the socket 201 are all made of hard insulating materials, such as hard plastic, which is convenient for applying force to the plug 202 to avoid squeezing the cable itself and avoiding bending between the connection of the two cable units, thereby reducing damage to the cable. At the same time, in order to facilitate the connection between the socket 201 and the plug 202, the surface of the gripping block 5 is provided with anti-slip grooves 6.

[0057] The usage process or working principle of this easy-to-connect flexible flat cable is:

[0058] According to the needs of the usage scenario, a suitable number of cable units are selected to connect them. When connecting two cable units, the plug 202 is inserted into the socket 201. During this process, the connector 204 enters the connection seat 203, and the roller 2 contacts the socket 201. The plug 202 smoothly enters the socket 201 through the rotation of the roller 2 and the ball 1. When the plug 202 enters the socket 201, the block 302 is pushed outward. After the plug 202 completely enters the socket 201, the magnet 3 and the iron plate 4 contact and attract each other. The block 302 contacts the plug 202 and the end of the limit frame away from the socket 201 to lock the plug 202. At the same time, the baffle 304 is pushed to the side of the clamping plate 301 close to the socket 201 to block the clamping plate 301 to achieve the connection of the two cable units. Multiple cable units are connected in the above manner, and then the connected flat cable is connected to the device for use.

[0059] When the two cable units need to be disassembled, slide the baffle 304 to a position away from the clamp 301, press the clamp 301 inward to move the block 302 away from the plug 202, and drive the push plate 501 to push the plug 202 outward under the elastic force of the compression spring 502, push the plug 202 out of the inside of the socket 201 for a distance, and then pull the plug 202 out of the inside of the socket 201.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
