Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cables, and in particular to a flexible cable for new energy vehicles. Background Art
[0002] New energy cables play a vital role in new energy vehicles. They connect key components such as batteries, motors, and controllers to ensure efficient and stable transmission of electricity. Compared with traditional cables, new energy cables have significant differences in material selection, structural design, and performance requirements. New energy cables are designed to withstand higher voltage and current loads. For example, on-board cables can reach specifications of 600V / 300A, so they are thicker and heavier. At the same time, they also need to have the ability to work normally under extreme temperatures, which requires the material to withstand a temperature range from -40°C to 150°C, and also needs to have good flexibility and bending properties to adapt to different installation environments.
[0003] At present, new energy vehicles have thicker and heavier cables, and the car will inevitably encounter shaking or severe vibration during driving, which may cause the male and female heads to become disconnected and separated due to shaking or vibration.
[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art. Summary of the invention
[0005] The purpose of the present invention is to design a flexible cable that will not cause the male connector and the female connector to become disconnected and separated when a car shakes during driving, so as to solve the above-mentioned shortcomings in the technology.
[0006] In order to achieve the above-mentioned objectives, the present invention provides the following technical solutions: a flexible cable for new energy vehicles, comprising a male head and a female head at the end of a cable harness, the female head having an anti-foolproof groove, the male head having a protective cover, the inner wall of the protective cover having an anti-foolproof protrusion that cooperates with the anti-foolproof groove, when the contact conductor in the male head is inserted into the contact conductor in the female head, the inner wall of the protective cover fits with the outer wall of the female head, a blind groove is provided in the anti-foolproof protrusion, a compression groove and a first exhaust groove are provided in the male head, the compression groove is parallel to the blind groove and has the same cross-sectional area, a stop groove and a second exhaust groove are provided on the protective cover, the first exhaust groove, the second exhaust groove, the compression groove and the inner cavity of the protective cover are connected, a shift block is slidably connected in the blind groove, and a third exhaust groove runs through the shift block.
[0007] Preferably, the shift block includes a first block slidably connected in the blind groove, and a second block fixedly connected to the top of the first block, the second block is slidably connected in the stop groove, and the third exhaust groove is opened on the first block.
[0008] Preferably, when the second block is in contact with the end of the retaining groove, the first exhaust groove and the second exhaust groove are both connected to the third exhaust groove.
[0009] Preferably, limiting grooves are provided on both sides of the first block, and limiting blocks fixedly connected to the fool-proof protrusions are slidably connected in the limiting grooves.
[0010] Preferably, when the end of the limiting groove away from the female head is in contact with the limiting block, the first block does not overlap with the first exhaust groove.
[0011] Preferably, the distance between the top surface of the second block and the central axis of the male head is greater than the distance between the outer wall of the protective sleeve and the central axis of the male head.
[0012] Preferably, the second top surface has anti-slip texture.
[0013] In the above technical solution, the technical effects and advantages provided by the present invention are: When the male connector is connected to the female connector, the female connector will squeeze out the air in the protective cover, and finally push the shifting block to isolate the inner cavity of the protective cover from the outside air. At this time, when the male connector and the female connector are away from each other, because the air pressure in the protective cover is lower than the outside air pressure, it will be difficult for the male connector and the female connector to separate from each other, thus solving the problem of the male connector and the female connector being disconnected and separated due to the shaking of the car during driving; When disassembling the male head and the female head, the shifting block can be further moved toward the male head so that the first block is inserted into the compression groove, and the third exhaust groove connects the first exhaust groove with the second exhaust groove, so that the outside air can be sucked into the protective cover, so that the female head can be pulled out of the protective cover and the female head is separated from the male head.

DETAILED DESCRIPTION
[0017] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0019] The present invention provides Figure 1-5A flexible cable for new energy vehicles shown in the figure comprises a male connector 1 and a female connector 2 at the end of a cable harness, the female connector 2 is provided with an anti-foolproof groove 3, the male connector 1 is provided with a protective sleeve 4, the inner wall of the protective sleeve 4 is provided with an anti-foolproof protrusion 5 that cooperates with the anti-foolproof groove 3, when the contact conductor in the male connector 1 is inserted into the contact conductor in the female connector 2, the inner wall of the protective sleeve 4 is fitted with the outer wall of the female connector 2, and is characterized in that: a blind groove 6 is provided in the anti-foolproof protrusion 5, a compression groove 7 and a first exhaust groove 8 are provided in the male connector 1, and the compression groove 7 is parallel to the blind groove 6 and cross-sectionally The protective sleeve 4 has the same area, a retaining groove 9 and a second exhaust groove 10 are provided on the protective sleeve 4, the first exhaust groove 8, the second exhaust groove 10, the compression groove 7 and the inner cavity of the protective sleeve 4 are connected, the first block 11a is slidably connected in the blind groove 6, the second block 11b is fixedly connected to the top of the first block 11a, the second block 11b is slidably connected in the retaining groove 9, the first block 11a is penetrated by a third exhaust groove 12, the first block 11a and the second block 11b together constitute the shifting block 11, the distance between the top surface of the second block 11b and the central axis of the male head 1, The second block 11b has a non-slip texture on the top surface, which is convenient for the user to press the dial block 11 with his thumb. When the second block 11b is in contact with the end of the stop groove 9, the first exhaust groove 8 and the second exhaust groove 10 are both connected with the third exhaust groove 12, ensuring that when the user presses the dial block 11 away from the female head 2, the outside air can enter the inner cavity of the protective cover 4 through the second exhaust groove 10, the third exhaust groove 12 and the first exhaust groove 8, so that the air pressure in the protective cover 4 is consistent with the outside air pressure, thereby preventing the air from leaking out due to the leakage of the protective cover 4. The air pressure is lower than the outside air pressure, which makes it difficult to pull the male connector 1 out of the female connector 2. The first block 11a has limit grooves 13 on both sides. The limit grooves 13 are slidably connected with limit blocks 14 fixedly connected to the fool-proof protrusions 5. When the limit groove 13 is away from the end of the female connector 2 and fits with the limit block 14, the first block 11a does not overlap with the first exhaust groove 8. In this way, when the female connector 2 pushes the shifting block 11, the male connector 1 will not be completely inserted into the female connector 2. The first block 11a will isolate the first exhaust groove 8 from the second exhaust groove 10. When in use, the user first presses the anti-slip texture on the surface of the second block 11b with the thumb, and then pushes the second block 11b away from the male head 1. The second block 11b will drive the first block 11a to slide in the blind groove 6. When the limit block 14 contacts the end of the limit groove 13, the shift block 11 cannot be pushed further. At this time, the first exhaust groove 8, the second exhaust groove 10, the compression groove 7 and the inner cavity of the protective sleeve 4 are connected. Then the user pinches the male head 1, no longer presses the second block 11b, and aligns the fool-proof protrusion 5 on the male head 1 with the female head 2. The foolproof groove 3 is inserted, and then the contact conductor of the male connector 1 is inserted into the contact conductor of the female connector 2. At this time, the female connector 2 is inserted into the protective cover 4, and the air in the inner cavity of the protective cover 4 is gradually squeezed out through the first exhaust groove 8 and the second exhaust groove 10. When the female connector 2 contacts the shift block 11, the first block 11a is gradually pushed to move in the blind groove 6. When the male connector 1 is completely inserted into the female connector 2, the first block 11a is inserted into the compression groove 7, and the first exhaust groove 8 and the second exhaust groove 10 are isolated. At this time, the inner cavity of the protective cover 4 is not connected to the outside air; When the female connector 2 and the male connector 1 tend to move away from each other, the space in the protective cover 4 becomes larger. Since the first block 11a isolates the inner cavity of the protective cover 4 from the outside air, the air pressure in the protective cover 4 becomes lower. Therefore, the outside atmospheric pressure presses the female connector 2 into the protective cover 4, thereby preventing the male connector 1 and the female connector 2 from being disconnected and separated due to the shaking of the car during driving after the male connector 1 and the female connector 2 are connected. When the male head 1 and the female head 2 need to be disassembled, the user uses the thumb to move the second block 11b further away from the end of the female head 2, so that the first block 11a continues to be inserted into the compression groove 7. As the first block 11a continues to be inserted into the compression groove 7, the air in the compression groove 7 is compressed. When the second block 11b fits with the end of the retaining groove 9, the first exhaust groove 8, the second exhaust groove 10 and the third exhaust groove 12 are connected. At this time, the inner cavity of the protective sleeve 4 is connected with the outside air. When the female head 2 is pulled out of the protective sleeve 4, the outside air can be sucked in to ensure that the air pressure in the protective sleeve 4 is consistent with the outside air, thereby facilitating the separation of the male head 1 and the female head 2. The air in the compression groove 7 is squeezed to generate high pressure. When the shift block 11 is released, a thrust is generated to push the shift block 11 away from the male head 1, so that the first block 11a moves toward the female head 2. When the limit block 14 contacts the end of the limit groove 13, the shift block 11 stops moving.
