Description

Technical Field

[0001] The present invention relates to the technical field of cable connection, and in particular to a new energy flexible aluminum alloy cable quick connection device and method. Background Art

[0002] The main problems currently faced by new energy vehicles are still small battery capacity and slow charging speed. Relevant industries are vigorously developing fast charging and quick charging technologies. Therefore, cables specially designed for new energy systems are generally aluminum alloy cables with multiple conductors inside. The wiring method of new energy cables currently used still draws on the traditional cable conductor connection method, that is, the male and female heads of the cable are directly plugged in to electrically connect the two. If there is relative rotation between the male and female heads, torque will be generated to cause damage to the joint. If there is axial relative displacement between the male and female heads, the male and female heads will be loosened, and the purpose of electrical connection will not be achieved.

[0003] 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

[0004] The purpose of the present invention is to design a device that can prevent relative rotation and relative axial movement between the male and female heads after they are plugged together, so as to solve the above-mentioned shortcomings in the technology.

[0005] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a new energy flexible aluminum alloy cable quick docking device, comprising a male head and a female head, the male head and the female head are plugged into each other, an inner joint is fixedly installed on the outer wall of the male head, and an outer joint is fixedly installed on the outer wall of the female head;

[0006] The inner joint comprises a first fixing member fixedly mounted on the outer wall of the male head, a first connecting member fixedly mounted on one end of the first fixing member close to the female head, a first arc-shaped piece fixedly mounted on the end of the first connecting member and opening upward, and an arc-shaped stopper fixedly mounted on both ends of the top of the first arc-shaped piece, with the protruding part of the arc-shaped stopper facing the female head;

[0007] The external joint includes a second fixing member fixedly mounted on the outer wall of the female head, two limit strips fixedly mounted on the outer wall of the second fixing member, and clamping strips with protruding ends at opposite sides of the two limit strips, and the two limit strips are respectively matched with the concave parts of the two arc-shaped stop plates;

[0008] By aligning the central axes of the female head and the male head, they are close to each other and plugged into each other, so that the recessed parts of the two arc-shaped stop plates are respectively fitted with the outer walls of the two limit strips, and at the same time, the side walls of the clamping strip are fitted with the side walls of the arc-shaped stop plates. The clamping strip buckles the arc-shaped stop plates to prevent the male head and the female head from axially displacing relative to each other, and the two limit strips clamp the two arc-shaped stop plates to prevent the male head and the female head from axially rotating relative to each other.

[0009] Preferably, the arc-shaped stop plate includes a contact portion fitted with the outer wall of the female head, a transition portion fixedly installed at the top of the contact portion, and a force-bearing portion fixedly installed at the top of the transition portion, and the contact portion, transition portion and force-bearing portion are all fitted with the outer wall of the limit strip.

[0010] Preferably, the arc-shaped stop plate and the limit strip are both plastic components, the limit strip is arranged in a shuttle shape, the distance between the limit strip and the surface of the female head is the thickness of the contact part, and the distance between the limit strip and the surface of the female head is smaller than the thickness of the transition part.

[0011] Preferably, when the limit strip is not in contact with the arc-shaped stop piece, the contact portion is not in contact with the surface of the female head, and when the limit strip is in contact with the arc-shaped stop piece, the contact portion is in contact with the female head.

[0012] Preferably, the cross section of the clip strip is arranged to be a triangle, with the hypotenuse of the triangle facing the male head.

[0013] Preferably, the cross section of the first connecting member is set to be semicircular, the inner diameter of the first connecting member is the same as the outer diameter of the female head, and a guide groove is formed between the first connecting member, the arc-shaped stopper and the first fixing member.

[0014] Preferably, the external joint also includes a second connecting rod fixedly connected to one side of the second connecting member, and a second arc-shaped piece fixed at the end of the second connecting rod, and the two ends of the second arc-shaped piece are respectively slidably connected to the guide groove. The cross-section formed when the second arc-shaped piece is in contact with the guide groove is circular, and the inner diameter of the circle is the same as the outer diameter of the male head.

[0015] Preferably, when the second arc-shaped piece is in contact with the guide groove, two arc-shaped stop pieces are respectively located on both sides of the second connecting rod.

[0016] In a second aspect, the present invention further provides a method for operating a new energy flexible aluminum alloy cable quick docking device, the method comprising the steps of:

[0017] S1. The opening of the second arc-shaped piece on the outer joint faces the guide groove, and the female head is squeezed between the two arc-shaped stoppers until the outer wall of the female head fits with the first arc-shaped piece, and the second arc-shaped piece fits with the guide groove;

[0018] S2. Bring the male and female heads whose central axes coincide with each other closer together until the two arc-shaped stoppers fit into the two limit strips;

[0019] S3. Pinch the force-bearing parts on the two arc-shaped stoppers and bring them close to each other so that the contact part can be located between the female connector and the limit strip. Continue to move the male connector and the female connector close to each other until the connection is completed. At this time, the arc-shaped stoppers are buckled by the clamping strip.

[0020] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0021] When the contact portion, transition portion and force-bearing portion are in contact with the limit strip at the same time, and there is a tendency for the head and the male head to rotate relative to each other axially, the limit strip has a tendency to squeeze the transition portion to deform toward the surface of the female head. The deformation resistance of the female head surface cooperates with the deformation resistance of the transition portion to jointly prevent the limit strip from squeezing the transition portion, thereby preventing the limit strip from rotating;

[0022] The device also wraps one side of the limit strip by turning the force-bearing part outward, so that when the limit strip rotates, the force-bearing part needs to be pushed outward. The force-bearing part is subjected to tension and has a tendency to pull the transition part, and the strength of the force-bearing part is used to prevent the limit strip from rotating.

[0023] When the limit strip is connected to the arc-shaped stop plate, it not only limits the relative axial rotation between the male head and the female head, but also automatically locks the arc-shaped stop plate through the automatic clamping strip to prevent relative axial displacement between the male head and the female head, thereby preventing loosening.

[0031] 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.

[0032] 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.

[0033] The present invention provides Figure 1-4 A new energy flexible aluminum alloy cable quick docking device shown in the figure includes a male head 1 and a female head 2, which are plugged into each other, and an inner joint 3 is fixedly installed on the outer wall of the male head 1, and an outer joint 4 is fixedly installed on the outer wall of the female head 2. The inner joint 3 includes a first fixing member 301 fixedly installed on the outer wall of the male head 1, a first connecting member 302 fixedly installed on the first fixing member 301 close to one end of the female head 2, a first arc-shaped piece 303 fixedly installed on the end of the first connecting member 302 and opening upward, and an arc-shaped stopper 304 made of plastic material fixedly installed on both ends of the top of the first arc-shaped piece 303, the protruding part of the arc-shaped stopper 304 faces the female head 2, and a guide is formed between the first connecting member 302, the arc-shaped stopper 304 and the first fixing member 301. Slot 5, the external joint 4 includes a second fixing member 401 fixedly mounted on the outer wall of the female head 2, two shuttle-shaped limiting strips 402 made of plastic material fixedly mounted on the outer wall of the second fixing member 401, a second connecting rod 404 fixedly connected to one side of the second connecting member, a second arc-shaped piece 405 fixed at the end of the second connecting rod 404, and a clamping strip 403 with a triangular cross section, which is convexly arranged at the ends of the opposite sides of the two limiting strips 402, and the two limiting strips 402 are respectively matched with the concave parts of the two arc-shaped stopping pieces 304, and the arc-shaped stopping pieces 304 include a contact portion 304a fitted with the outer wall of the female head 2, a transition portion 304b fixedly mounted at the top of the contact portion 304a, and a force-bearing portion 304c fixedly mounted at the top of the transition portion 304b;

[0034] The user brings the male connector 1 and the female connector 2 closer together, so that the opening of the second arc-shaped piece 405 on the external connector 4 faces the guide groove 5, and then moves the female connector 2 between the two arc-shaped stopper pieces 304. The female connector 2 will first contact the force-bearing portion 304c, and the force-bearing portion 304c will drive the transition portion 304b and the contact portion 304a to deform in shape and thus move away from the female connector 2. When the outer wall of the female connector 2 fits with the first arc-shaped piece 303, the two arc-shaped stopper pieces 304 are reset, and the second arc-shaped piece 405 fits with the guide groove 5. At this time, the central axes of the female connector 2 and the male connector 1 are automatically aligned, and the interfaces in the male connector 1 and the female connector 2 are also automatically aligned, so there is no need to worry about the conductors being inserted crookedly and causing the plug-in to fail.

[0035] Then the user gradually brings the male head 1 and the female head 2 closer together, and pinches the force-bearing parts 304c on the two arc-shaped stop pieces 304 closer together, so that the contact parts 304a on the two arc-shaped stop pieces 304 can be located between the female head 2 and the limiting strip 402. At this time, the contact parts 304a will fit with the outer wall of the female head 2 to increase friction. It is necessary to insert the male head 1 into the female head 2 with force. When the triangular inclined surface of the clamping strip 403 on the limiting strip 402 fits with the outer wall of the arc-shaped stop piece 304, the limiting strip 402 will have one end of the clamping strip 403 deformed, so that the two arc-shaped stop pieces 304 can move between the two limiting strips 402. When the clamping strip 403 buckles the arc-shaped stop piece 304, the installation of this quick-connect device is completed.

[0036] When there is a tendency for relative axial rotation between the female head 2 and the male head 1, the limiting strip 402 has a tendency to squeeze the transition part 304b to deform toward the surface of the female head 2. The deformation resistance of the surface of the female head 2 cooperates with the deformation resistance of the transition part 304b to jointly prevent the limiting strip 402 from squeezing the transition part 304b, thereby preventing the limiting strip 402 from rotating. The force-bearing part 304c turns outward to wrap one side of the limiting strip 402, so that when the limiting strip 402 rotates, the force-bearing part 304c needs to be pushed outward. The force-bearing part 304c is subjected to tension and has a tendency to pull the transition part 304b. The strength of the force-bearing part 304c is used to prevent the limiting strip 402 from rotating. When there is a relative axial displacement between the male head 1 and the female head 2, the clamping strip 403 on the limiting strip 402 will clamp the edge of the arc-shaped stopper 304 to prevent the arc-shaped stopper 304 from detaching from between the two limiting strips 402.

[0037] In combination with a new energy flexible aluminum alloy cable quick docking device, the present invention also provides a method for operating the new energy flexible aluminum alloy cable quick docking device, the method comprising the steps of:

[0038] S1. The opening of the second arc-shaped piece 405 on the external joint 4 is facing the guide groove 5, and the female head 2 is squeezed between the two arc-shaped stoppers 304 until the outer wall of the female head 2 fits with the first arc-shaped piece 303, and the second arc-shaped piece 405 fits with the guide groove 5;

[0039] S2. The male head 1 and the female head 2 whose central axis coincide with each other are brought close to each other until the two arc-shaped stoppers 304 fit with the two limit strips 402;

[0040] S3. Pinch the force-bearing parts 304c on the two arc-shaped stoppers 304 and bring them close to each other so that the contact part 304a can be located between the female connector 2 and the limiting strip 402, and continue to move the male connector 1 and the female connector 2 close to each other until the insertion is completed. At this time, the locking strip 403 buckles the arc-shaped stopper 304.

[0041] It is important to note that the construction and arrangement of the present application shown in a number of different exemplary embodiments are exemplary only. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, colors, changes in orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
