Description
Technical Field
[0001] This utility model relates to the technical field of flat wire harness connection devices, and in particular to a lightweight flat wire harness connection device. Background Technology
[0002] Flat wire harness connectors are electronic components used to connect flat wire harnesses. They are mainly used in electronic devices for transmitting signals and power. They are characterized by their compact structure, reliable connection, lightweight design, and easy installation, and are widely used in consumer electronics, automotive electronics, industrial equipment, and other fields.
[0003] When connecting to electronic devices using a flat wire harness connector, if the connector is inserted vertically into the electronic device and the wire harness and connector are also perpendicular to each other, the connection between the wire harness and the connector will be severely misaligned. This can easily cause the connection between the wire harness and the connector to become loose or break, affecting the normal transmission and connection effect of the wire harness and rendering the wire harness unusable. Utility Model Content
[0004] The purpose of this invention is to solve the problem that when the connecting device is inserted vertically into the electronic device, the connection between the wire harness and the connecting device is severely misaligned, which can easily cause the connection between the wire harness and the connecting device to become loose or break, affecting the normal transmission and connection effect of the wire harness and making the wire harness unusable. Therefore, a lightweight flat wire harness connecting device is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight flat wire harness connection device, comprising a connector and a flat wire body, one end of the flat wire body being connected to one end of the inner wall of the connector by welding, the outer surface of the connector being provided with an orientation structure that can restrict the angle and position of the outer surface of the flat wire body near the connector, the orientation structure comprising a groove rod, the outer surface of the groove rod being provided with a through groove through which the flat wire body can pass.
[0006] Preferably, the orientation structure further includes two rectangular rods, one side of which is fixedly connected to a rotating shaft. The two rectangular rods are respectively mounted on one side of the connector via the rotating shaft, and the rectangular rods can be rotated by the rotating shaft. A threaded ring is threadedly connected to the outer surface of one of the rotating shafts. A circular ring is rotatably connected to one side of the threaded ring, and a plug rod is fixedly connected to one side of the circular ring. A plurality of plug holes are opened on one side of the connector, and the plug holes are circumferentially distributed on the outer side of the connector. The two ends of the groove rod are rotatably connected to the sides of the two rectangular rods that are close to each other.
[0007] The effect achieved by the above components is as follows: By setting the grooved rod, when welding the connecting device, one end of the flat wire can pass through the through groove on the outer surface of the grooved rod and be inserted into the connector from the top of the grooved rod to weld with the connector. If the flat wire is inserted into the equipment and connected to the equipment, and the angle between the end of the flat wire near the connector and the connector tends to be perpendicular due to position and length limitations, the rectangular rods on both sides of the connector can be pushed to rotate upward through the rotating shaft. The angle between the rectangular rod and the grooved rod and the connector is adjusted so that the angle between the outer surface of the flat wire near the connector and the connector tends to be parallel. The flat wire on the outer surface of the grooved rod will be in a bent state. Then, the threaded ring on the outer surface of the rotating shaft is rotated so that the threaded ring moves towards the connector on the outer surface of the rotating shaft. The ring is pushed to move and insert the insertion rod on one side of the ring into the insertion hole on the side of the connector, thus fixing the angle between the rectangular rod and the connector and the position of the grooved rod.
[0008] Preferably, the inner edges of the through groove on the outer surface of the groove rod are arc-shaped.
[0009] The effect achieved by the above components is that by setting the inner walls of the groove on the outer surface of the groove rod to be arc-shaped, when the flat line body is located inside the groove on the outer surface of the groove rod, the contact between the surface and the inner wall edge of the groove is less likely to cause wear and breakage.
[0010] Preferably, a protruding rod is fixedly connected to one side of the threaded ring, and the protruding rod is located on the outer surface of the threaded ring near the rectangular rod.
[0011] The effect achieved by the above components is that the rotation of the threaded ring can be more easily controlled and the position of the threaded ring and the insert rod can be adjusted by pushing the protruding rod on the outer surface of the threaded ring by hand.
[0012] Preferably, the outer surface of the grooved rod is provided with a clamping component that can further restrict the position of the flat wire inside the grooved rod.
[0013] Preferably, the clamping assembly includes a U-shaped rod, a pressure rod, and two springs. The U-shaped rod is fixed to the top of the grooved rod, and round rods are slidably connected to both sides of the inner wall of the U-shaped rod. The two springs are located on the outer sides of the two round rods respectively, and the round rods slide on the inner wall of the U-shaped rod. The top of the pressure rod is fixedly connected to the bottom of the round rods.
[0014] The effect achieved by the above components is that when the outer surface of the flat wire is located inside the through groove on the outer surface of the grooved rod, the spring pushes the pressure rod to press the pressure rod onto the outer surface of the flat wire, further securing the flat wire inside the through groove and preventing the flat wire from moving easily.
[0015] Preferably, the outer surface of the round rod slides on the inner wall of the U-shaped rod and the inner wall of the grooved rod.
[0016] The effect achieved by the above components is that by setting the round rod, the angle between the pressure rod and the groove rod can be further restricted, so as to avoid the angle between the pressure rod and the groove rod being deflected when the pressure rod is subjected to force on one side.
[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0018] In this invention, by setting an orientation structure and allowing one end of the flat wire to pass through the through groove on the outer surface of the grooved rod, when connecting the connector to the equipment, if the angle between the end of the flat wire near the connector and the connector is close to perpendicular, the angle between the end of the flat wire near the connector and the connector is adjusted by pushing the rectangular rod to control the rotation of the grooved rod. This makes the angle between the outer surface of the flat wire near the connector and the connector tend to be parallel, thus minimizing the risk of excessive deflection angle between the end of the flat wire near the connector and the connector, which could lead to breakage or loosening at the connection point and affect the normal use of the connection device.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] Example 1, such as Figure 1-2 As shown, a lightweight flat wire harness connection device includes a connector 1 and a flat wire body 3. One end of the flat wire body 3 is connected to one end of the inner wall of the connector 1 by welding. The outer surface of the connector 1 is provided with an orientation structure 2 that can limit the angle and position of the outer surface of the flat wire body 3 near the connector 1. The orientation structure 2 includes a groove rod 27, and the outer surface of the groove rod 27 is provided with a through groove through which the flat wire body 3 can pass.
[0030] Reference Figure 1-5As shown, this embodiment discloses that the orientation structure 2 also includes two rectangular rods 21. A rotating shaft 22 is fixedly connected to one side of each of the two rectangular rods 21. The two rectangular rods 21 are respectively mounted on one side of the connector 1 via the rotating shaft 22. The rectangular rods 21 can be rotated by the rotating shaft 22. A threaded ring 23 is threaded onto the outer surface of one rotating shaft 22. A circular ring 24 is rotatably connected to one side of the threaded ring 23. A plug rod 25 is fixedly connected to one side of the circular ring 24. Several insertion holes 26 are provided on one side of the connector 1, and the insertion holes 26 are circumferentially distributed on the outer side of the connector 1. The two ends of the grooved rod 27 are respectively connected to two rectangular rods 21. The rectangular rods 21 are rotatably connected on their adjacent sides. By setting the grooved rod 27, when welding the connecting device, one end of the flat wire 3 can pass through the through groove on the outer surface of the grooved rod 27 and be inserted into the connector 1 from the top of the grooved rod 27 for welding. If the flat wire 3 is inserted into the equipment and connected to the equipment, and the angle between the end of the flat wire 3 near the connector 1 and the connector 1 tends to be perpendicular due to position and length limitations, the rectangular rods 21 on both sides of the connector 1 can be pushed to rotate upward through the rotating shaft 22 to adjust the angle between the rectangular rods 21 and the grooved rod 27 and the connector 1. The angle between the portion of the flat wire 3 near the outer surface of the connector 1 and the connector 1 tends to be parallel. The flat wire 3 located on the outer surface of the grooved rod 27 will be in a bent state. Then, the threaded ring 23 on the outer surface of the rotating shaft 22 is rotated, causing the threaded ring 23 to move towards the connector 1 on the outer surface of the rotating shaft 22. This pushes the ring 24 to move, inserting the insertion rod 25 on one side of the ring 24 into the insertion hole 26 on one side of the connector 1. The angle between the rectangular rod 21 and the connector 1 and the position of the grooved rod 27 are fixed. By setting the orientation structure 2, one end of the flat wire 3 passes through the grooved rod 27. When connecting connector 1 to the equipment, if the angle between the end of flat wire 3 near connector 1 and connector 1 is close to perpendicular, the angle between the end of flat wire 3 near connector 1 and connector 1 can be adjusted by pushing rectangular rod 21 to control the rotation of groove rod 27. This makes the angle between the outer surface of flat wire 3 near connector 1 and connector 1 tend to be parallel, thus avoiding excessive deflection angle between the end of flat wire 3 near connector 1 and connector 1, which could lead to breakage or loosening at the connection between flat wire 3 and connector 1, affecting the normal use of the connection device.
[0031] Reference Figure 2-5As shown, this embodiment discloses that the inner walls of the through groove on the outer surface of the groove rod 27 are arc-shaped. By setting the inner walls of the through groove on the outer surface of the groove rod 27 to be arc-shaped, when the flat wire body 3 is located inside the through groove on the outer surface of the groove rod 27, the contact between the surface and the inner wall edge of the through groove is less likely to cause wear and breakage. A protruding rod 29 is fixedly connected to one side of the threaded ring 23. The protruding rod 29 is located on the outer surface of the threaded ring 23 near the rectangular rod 21. By pushing the protruding rod 29 on the outer surface of the threaded ring 23 by hand, it is easier to control the rotation of the threaded ring 23 and adjust the position of the threaded ring 23 and the insert rod 25.
[0032] Reference Figure 2-5 As shown, this embodiment discloses that the outer surface of the groove rod 27 is provided with a clamping component 28, which can further restrict the position of the flat wire 3 inside the groove rod 27.
[0033] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, this embodiment discloses a clamping assembly 28 including a U-shaped rod 281, a pressure rod 283, and two springs 284. The U-shaped rod 281 is fixed to the top of the grooved rod 27. Round rods 282 are slidably connected to both sides of the inner wall of the U-shaped rod 281. The two springs 284 are respectively located on the outer sides of the two round rods 282. The round rods 282 slide on the inner wall of the U-shaped rod 281. The top of the pressure rod 283 is fixedly connected to the bottom of the round rod 282. The outer surface portion of the flat wire body 3 is located in the through groove on the outer surface of the grooved rod 27. When the spring 284 pushes the pressure rod 283, the pressure rod 283 can be pressed against the outer surface of the flat wire body 3, further securing the flat wire body 3 in the position inside the through groove, so that the flat wire body 3 will not move easily. The outer surface of the round rod 282 slides on the inner wall of the U-shaped rod 281 and the inner wall of the groove rod 27. By setting the round rod 282, the angle between the pressure rod 283 and the groove rod 27 can be further restricted, so as to avoid the angle between the pressure rod 283 and the groove rod 27 being deflected when the pressure rod 283 is subjected to force on one side.
[0034] Working principle: When welding the connection device, one end of the flat wire 3 can be passed through the through groove on the outer surface of the grooved rod 27 and inserted into the connector 1 from above the grooved rod 27 for welding. If the connector 1 is inserted into the equipment and connected to the equipment, and the angle between the end of the flat wire 3 near the connector 1 tends to be perpendicular to each other due to position and length limitations, the rectangular rods 21 on both sides of the connector 1 can be pushed to rotate upward through the rotating shaft 22. The angle between the rectangular rod 21 and the grooved rod 27 and the connector 1 is adjusted so that the angle between the part of the flat wire 3 near the outer surface of the connector 1 and the connector 1 tends to be parallel. The flat wire 3 located on the outer surface of the grooved rod 27 will be in a bent state. Then, the threaded ring 23 on the outer surface of the rotating shaft 22 is rotated so that the threaded ring 23 moves in the direction of the connector 1 on the outer surface of the rotating shaft 22. This pushes the ring 24 to move and inserts the insertion rod 25 on one side of the ring 24 into the insertion hole 26 on one side of the connector 1, thus fixing the angle between the rectangular rod 21 and the connector 1 and the position of the grooved rod 27.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
