Description

Technical Field

[0001] The present invention relates to the field of automotive conductive connection components, and more specifically, to a connector assembly for new energy vehicles. Background Art

[0002] Most new energy vehicles are electric or mainly powered by electricity and supplemented by fuel. Such vehicles require extensive use of wire harness connections to transmit kinetic energy or signals through the wire harnesses.

[0003] Compared with a complete wire, the connector assembly has a relatively obvious change in resistance at the connection part. Therefore, the current conduction at the connection is worse than that of a complete wire. As a result, the connection is very sensitive to current. When the current is too large, the temperature at the connection is higher than that of the wire, which may seriously cause damage to the connection assembly. If the connection assembly is not disconnected in time, even combustion may occur.

[0004] In the prior art, a pop-up mechanism is generally set to disconnect the connection assembly when it overheats. However, the existing pop-up mechanisms are generally arranged inside the connection assembly, and the stroke of the pop-up mechanism is short. Therefore, the distance to separate the connection assembly is limited, and thus the distance for the connection assembly to pop out of the connector plug is short, which is likely to cause the problem that the two ends of the wire are close to each other. When the two ends of the wire are close to each other, an arc is likely to be generated, and the generated arc can ignite the vehicle, leading to vehicle spontaneous combustion and further causing danger.

[0005] Therefore, those skilled in the art have provided a connector assembly for new energy vehicles to solve the problems raised in the above background art. Summary of the Invention

[0006] The purpose of the present invention is to provide a connector assembly for new energy vehicles to solve the problems raised in the above background art.

[0017] Furthermore, the end of the blocking plate is provided with a locking surface that matches the supporting surface.

[0018] Furthermore, the force storage assembly includes a rotating shell, which is fixedly connected to the jack frame. A torsion spring is arranged inside the rotating shell, and an extension shaft is arranged at one end of the torsion spring.

Specific embodiments

[0032] Next, in combination with the drawings and specific embodiments, the invention will be further described: Embodiment

[0033] Referring to Figure 1 - Figure 6 The new energy vehicle connector assembly disclosed by the present invention includes a male component 1, a female component 2, and an ejecting mechanism 3;

[0034] The male component 1 includes a jack frame 11. Inside the jack frame 11, there is a connecting plate 12. At the center of the connecting plate 12, there is a conductive jack 13. At one end of the connecting plate 12 away from the conductive jack 13, there is a wire connecting tube 14. At one end of the inside of the jack frame 11 away from the connecting plate 12, there is a closing cover 15;

[0035] The female component 2 includes a positioning plate 21. On the side wall of the positioning plate 21, there is a plug rod 22 that cooperates with the jack frame 11. Inside the plug rod 22, there is a conductive plug 23. Inside the positioning plate 21, there is a wire access tube 24 that cooperates with the conductive plug 23. At the top of the plug rod 22, there is a first locking component 25. At the bottom side of one end of the plug rod 22 facing the connecting plate 12, there is a second locking component 26;

[0036] The ejecting mechanism 3 includes a first shaft rod 31 and a second shaft rod 32. The first shaft rod 31 is rotatably connected to the jacking frame 11, and the second shaft rod 32 is rotatably connected to the side wall of the positioning plate 21. The positions of the first shaft rod 31 and the second shaft rod 32 correspond to each other. An arc-shaped plate 33 is rotatably arranged on the outer peripheral wall of the first shaft rod 31, and an energy storage assembly 34 is arranged on the side wall of the jacking frame 11.

[0037] In this embodiment, when the female head assembly 2 is inserted into the male head assembly 1, as Figure 1 and Figure 6 shown, the inserting rod 22 is inserted into the inside of the jacking frame 11 and presses down the closing cover 15, so that the closing cover 15 contacts the bottom wall of the jacking frame 11, and contacts the top wall of the inserting frame through the first locking assembly 25. The second locking assembly 26 contacts the end wall of the connecting plate 12 and is clamped with the closing cover 15 to achieve the effect of fixedly connecting the female head assembly 2 and the male head assembly 1. And during the closing process of the male head assembly 1 and the female head assembly 2, the second shaft rod 32 pushes the arc-shaped plate 33 to deflect, so that the arc-shaped plate 33 rotates and drives the energy storage assembly 34 to rotate, so as to realize storing internal energy through the energy storage assembly 34 and automatically ejecting the female head assembly 2 when the connector assembly overheats;

[0038] Specifically, when the connector assembly overheats, both the first locking assembly 25 and the second locking assembly 26 contract inward, so that the locking relationship between the inserting rod 22 and the jacking frame 11 is released. At this time, the internal energy stored in the energy storage assembly 34 is released, so that the arc-shaped plate 33 pushes the second shaft rod 32 to rotate and eject the female head assembly 2. As Figure 2 shown in the structural schematic diagram after the female head assembly 2 is pushed out, at this time the female head assembly 2 is completely located outside the male head assembly 1. At this time, the closing cover 15 automatically pops up, and the closing cover 15 shields the jacking frame 11, which can effectively isolate the male head assembly 1 and the female head assembly 2 completely, and can effectively prevent an arc from forming between the wires at both ends, thereby improving the safety of the device;

[0039] At the same time, through the setting of the arc-shaped plate 33, when the female head assembly 2 is pushed out, the female head assembly 2 can be effectively limited, avoiding the female head assembly 2 from falling and pulling out a large number of wires, achieving the purpose of protecting the vehicle wires and avoiding the problem of the remaining wires falling off due to wire pulling.

[0040] In a further preferred embodiment of the present invention, as Figure 3 and Figure 6 shown, the first locking assembly 25 includes a first sliding groove 251. The first sliding groove 251 is opened on the top side of the inserting rod 22. A top-out member 252 is slidably arranged inside the first sliding groove 251. One end of the top-out member 252 is provided with an inclined angle 253, and a first spring 254 connected to the top-out member 252 is arranged inside the first sliding groove 251.

[0041] In this embodiment, when the insertion rod 22 is inserted into the inside of the jack frame 11, the ejecting member 252 is pressed, the ejecting member 252 is completely pressed into the inside of the first chute 251, the first spring 254 is compressed, and the positioning plate 21 is pushed until the insertion rod 22 is inserted into the inside of the jack frame 11. When the insertion rod 22 is completely inserted into the inside of the jack frame 11, the first spring 254 rebounds and pushes the ejecting member 252 to move upward, thereby achieving the purpose of fixing the insertion rod 22.

[0042] In a further preferred embodiment of the present invention, as Figure 4 and Figure 6 shown, a limiting convex angle 16 is provided inside the jack frame 11, and the limiting convex angle 16 cooperates with the bevel angle 253.

[0043] In this embodiment, when the insertion rod 22 is inserted into the inside of the jack frame 11, the ejecting member 252 contacts the upper end wall of the jack frame 11 under the thrust of the first spring 254. At this time, the limiting convex angle 16 and the bevel angle 253 are in contact with each other, and then a supporting force is provided through the limiting convex angle 16 and the bevel angle 253 to prevent the insertion rod 22 from slipping out, and the stability of the insertion rod 22 inserted into the inside of the jack frame 11 can be effectively improved.

[0044] In a further preferred embodiment of the present invention, as Figure 3 and Figure 6 shown, the second locking assembly 26 includes a second chute 261, the second chute 261 is opened at the bottom end of the insertion rod 22, a support plate 262 is slidably arranged inside the second chute 261, a second spring 263 is arranged at the top end of the support plate 262, a pressing member 264 is arranged on the side wall of the support plate 262, and a supporting surface 265 is arranged at the bottom end of the pressing member 264.

[0045] In this embodiment, through the arrangement of the second spring 263, the support plate 262 is pushed downward, the pressing member 264 slides downward, and the pressing member 264 contacts the end wall of the closing cover 15 to form a clamping connection, further providing a supporting force for the insertion rod 22 and improving the tightness of the connection between the insertion rod 22 and the jack frame 11. The second spring 263 and the above-mentioned first spring 254 are both thermosensitive springs, and when in a high-temperature state, they will quickly retract, causing the support plate 262 to rise and the ejecting member 252 to contract downward.

[0046] In a further preferred embodiment of the present invention, as Figure 4 shown, the closing cover 15 includes a connecting shaft 151, the connecting shaft 151 is rotatably connected to the bottom wall of the jack frame 11, a blocking plate 152 is arranged on the side wall of the connecting shaft 151, and a torsion spring 153 is arranged inside the connecting shaft 151.

[0047] In this embodiment, the blocking plate 152 is rotatably connected to the jack frame 11 through the connecting shaft 151. When the blocking plate 152 is erected, the blocking plate 152 and the limiting convex corner 16 are in contact with each other. Figure 4 As shown, at this time, the torsion spring 153 has a lighter torsion, so that the blocking plate 152 can be tightly attached to the limiting convex corner 16. When the blocking plate 152 is twisted downward until it contacts the bottom wall of the jack frame 11, the torsion spring 153 will be twisted, so that the torsion spring 153 accumulates a large internal energy, so as to push the closing cover 15 to reset.

[0048] In a further preferred embodiment of the present invention, Figure 6 As shown, the end of the blocking plate 152 is provided with a locking surface 154 that matches the supporting surface 265 .

[0049] In this embodiment, the locking surface 154 cooperates with the limiting convex corner 16 to close the jack frame 11, and the locking surface 154 cooperates with the supporting surface 265 to achieve the purpose of limiting the insertion rod 22.

[0050] In a further preferred embodiment of the present invention, Figure 5 and Figure 6 As shown, the force storage assembly 34 includes a rotating shell 341, which is fixedly connected to the jack frame 11. A torsion spring 342 is arranged inside the rotating shell 341, and an extension shaft 343 is arranged at one end of the torsion spring 342. The extension shaft 343 penetrates the rotating shell 341 and is rotationally connected to the rotating shell 341. The extension shaft 343 is transmission-connected to the first shaft 31 through a bevel gear set 344.

[0051] In this embodiment, when the insertion rod 22 is inserted into the inside of the jack frame 11, the second shaft rod 32 slides inside the arc-shaped plate 33, causing the second shaft rod 32 to push the arc-shaped plate 33 to rotate. Since the arc-shaped plate 33 is fixedly connected to the first shaft rod 31, when the arc-shaped plate 33 rotates, it pushes the first shaft rod 31 to rotate synchronously. Then, through the bevel gear set 344 cooperating with the first shaft rod 31, the extension shaft rod 343 is driven to rotate, and the torsion spring 342 is rotated. Since the two ends of the torsion spring 342 are fixedly connected to the rotating housing 341 and the extension shaft rod 343 respectively, when the extension shaft rod 343 rotates, the torsion spring 342 will be deflected to accumulate torsion. When the insertion rod 22 is inserted into the inside of the jack frame 11, the insertion rod 22 is fixed to the jack frame 11. When an abnormal high temperature is formed inside the connector assembly due to connection problems, the high temperature causes the first spring 254 and the second spring 263 to contract, releasing the clamping relationship between the insertion rod 22 and the jack frame 11. At this time, the torsion accumulated by the torsion spring 342 drives the extension shaft rod 343 to rotate, and drives the first shaft rod 31 and the arc-shaped plate 33 to rotate, so as to achieve the effect of pushing the second shaft rod 32 by the arc-shaped plate 33 and ejecting the female head assembly 2.

[0052] In a further preferred embodiment of the present invention, as Figure 5 and Figure 6 shown, the arc-shaped plate 33 includes an installation ring 331 and an arc-shaped frame 332. The installation ring 331 is fixedly connected to the arc-shaped frame 332, and the installation ring 331 is fixedly connected to the first shaft rod 31. A sliding guide rail 333 is arranged inside the arc-shaped frame 332. The second shaft rod 32 is inserted into the inside of the sliding guide rail 333, and the linear distance between the two ends of the sliding guide rail 333 is greater than the length of the insertion rod 22.

[0053] In this embodiment, since the linear length between the two ends of the sliding guide rail 333 is greater than the length of the insertion rod 22, when the arc-shaped frame 332 pushes the second shaft rod 32 to deflect, it can effectively push the insertion rod 22 to completely withdraw from the jack frame 11. The installation ring 331 is used to fixedly connect the arc-shaped frame 332 to the first shaft rod 31.

[0054] The implementation principle of the above embodiment is as follows: The insertion rod 22 is inserted into the inside of the jack frame 11, and the closing cover 15 is pressed downwards, so that the closing cover 15 contacts the bottom wall of the jack frame 11. The ejecting member 252 is pushed upwards by the first spring 254. At the same time, the supporting plate 262 is pushed downwards by the second spring 263, so that the pressing member 264 and the ejecting member 252 contact the end of the closing cover 15 and the limiting convex angle 16 respectively, thereby fixedly installing the insertion rod 22 inside the jack frame 11. During the installation of the insertion rod 22, the second shaft rod 32 slides inside the arc-shaped plate 33, so that the second shaft rod 32 pushes the arc-shaped plate 33 to rotate. During the rotation of the arc-shaped plate 33, the extension shaft rod 343 is driven to rotate by the bevel gear set 344, and the torsion spring 342 is rotated to store torque. When the temperature inside the connector assembly is too high due to circuit problems, the high temperature causes the first spring 254 and the second spring 263 to contract, so that the pressing member 264 and the ejecting member 252 are retracted. At this time, the locking relationship between the insertion rod 22 and the jack frame 11 is released. The torque stored by the torsion spring 342 drives the extension shaft rod 343 to rotate, and drives the first shaft rod 31 and the arc-shaped plate 33 to rotate, so as to achieve the effect of pushing the second shaft rod 32 by the arc-shaped plate 33 to eject the female head assembly 2. And after the female head assembly 2 is ejected, the torsion spring 153 pushes the closing cover 15 to reset, and the closing cover 15 shields the jack frame 11, which can effectively isolate the male head assembly 1 from the female head assembly 2 completely, and can effectively prevent an arc from forming between the wires at both ends, thereby improving the safety of the device.

[0055] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
