Description

Technical Field

[0001] The present invention relates to the field of automotive conductive connection components, and in particular to a new energy automotive connector component. Background Art

[0002] Most new energy vehicles are electric or use electricity as the main fuel and a secondary fuel. Such vehicles require a large number of wiring harness connections to transmit kinetic energy or signals. Compared with the complete wire, the connector assembly has a more obvious change in resistance at the connection part, so the current conduction at the connection part is poorer than that of the complete wire. Therefore, the connection part is very sensitive to the current. When the current is too large, the temperature of the connection part will be higher than the temperature of the wire, which will seriously damage the connection component. If the connection component is not disconnected in time, it may even burn. In the prior art, a pop-up mechanism is generally provided to disconnect the connecting assembly when the connecting assembly is overheated. However, the existing pop-up mechanism is generally provided inside the connecting assembly, and the stroke of the pop-up mechanism is relatively short. Therefore, the distance for separating the connecting assembly is limited, and thus the distance for the connecting assembly to pop out of the connector plug is relatively short, which may easily cause the wires at both ends to be close to each other. When the wires at both ends are close to each other, an arc may be easily caused, and the generated arc may ignite the car, causing the car to spontaneously combust, thereby causing danger.

[0003] Therefore, those skilled in the art provide a new energy vehicle connector assembly to solve the problems raised in the above background technology. Summary of the invention

[0017] Below, the invention is further described in conjunction with the accompanying drawings and specific embodiments: Example:

[0018] Reference Figure 1 - Figure 6 , a new energy vehicle connector assembly disclosed in the present invention comprises a male assembly 1, a female assembly 2 and a pop-up mechanism 3; The male plug assembly 1 includes a jack frame 11, a connecting plate 12 is arranged inside the jack frame 11, a conductive jack 13 is arranged at the center of the connecting plate 12, a wire connecting tube 14 is arranged at one end of the connecting plate 12 away from the conductive jack 13, and a closing cover 15 is arranged at one end of the jack frame 11 away from the connecting plate 12; The female head assembly 2 includes a positioning plate 21, a side wall of the positioning plate 21 is provided with an insertion rod 22 matched with the jack frame 11, a conductive plug 23 is provided inside the insertion rod 22, a wire access tube 24 matched with the conductive plug 23 is provided inside the positioning plate 21, a first locking assembly 25 is provided at the top of the insertion rod 22, and a second locking assembly 26 is provided at the bottom side of one end of the insertion rod 22 facing the connecting plate 12; The pop-up mechanism 3 includes a first shaft rod 31 and a second shaft rod 32. The first shaft rod 31 is rotatably connected to the jack 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 plate 33 is rotatably provided on the outer peripheral wall of the first shaft rod 31, and a force storage assembly 34 is provided on the side wall of the jack frame 11.

[0019] In this embodiment, when the female component 2 is inserted into the male component 1, Figure 1 and Figure 6As shown, the insertion rod 22 is inserted into the interior of the jack frame 11, and the closing cover 15 is pressed down, so that the closing cover 15 and the bottom wall of the jack frame 11 are in contact with each other, and the first locking component 25 is in contact with the top wall of the insertion frame, and the second locking component 26 is in contact with the end wall of the connecting plate 12, and is mutually engaged with the closing cover 15, so as to achieve the effect of fixing the female component 2 and the male component 1 to each other, and in the process of closing the male component 1 and the female component 2, the second shaft rod 32 pushes the arc plate 33 to deflect, so that the arc plate 33 rotates, and drives the power storage component 34 to rotate, so as to achieve the purpose of accumulating internal energy through the power storage component 34, and automatically ejecting the female component 2 when the connector component is overheated; Specifically, when the connector assembly is overheated, the first locking assembly 25 and the second locking assembly 26 both contract inwardly, releasing the locking relationship between the insertion rod 22 and the jack frame 11. At this time, the internal energy stored in the power storage assembly 34 is released, causing the arc plate 33 to push the second shaft rod 32 to rotate, and the female head assembly 2 is ejected. Figure 2 The schematic diagram of the structure after the female component 2 is pushed out is shown, at this time, the female component 2 is completely located outside the male component 1, and the closing cover 15 automatically pops up, and the closing cover 15 shields the jack frame 11, which can effectively isolate the male component 1 from the female component 2, and can effectively avoid the formation of arcs between the wires at both ends, thereby improving the safety of the device; At the same time, through the setting of the arc plate 33, when the female head component 2 is pushed out, the female head component 2 can be effectively limited to prevent the female head component 2 from falling and pulling out a large number of wires, thereby protecting the vehicle wires and avoiding the problem of the guide pulling causing the remaining wires to fall off.

[0020] In a further preferred embodiment of the present invention, Figure 3 and Figure 6 As shown, the first locking assembly 25 includes a first slide groove 251, which is opened on the top side of the insertion rod 22, and an ejector 252 is slidably arranged inside the first slide groove 251, and an angle 253 is arranged at one end of the ejector 252, and a first spring 254 connected to the ejector 252 is arranged inside the first slide groove 251.

[0021] In this embodiment, when the insertion rod 22 is inserted into the interior of the jack frame 11, the ejector 252 is pressed to completely press the ejector 252 into the interior of the first slide groove 251, and the first spring 254 is compressed, and the positioning plate 21 is pushed until the insertion rod 22 is inserted into the interior of the jack frame 11. When the insertion rod 22 is completely inserted into the interior of the jack frame 11, the first spring 254 recovers and pushes the ejector 252 to move upward, thereby achieving the purpose of fixing the insertion rod 22.

[0022] In a further preferred embodiment of the present invention, Figure 4 and Figure 6 As shown, a limiting convex corner 16 is provided inside the jack frame 11 , and the limiting convex corner 16 matches with the oblique angle 253 .

[0023] In this embodiment, when the insertion rod 22 is inserted into the interior of the jack frame 11, the ejector 252 is pushed by the first spring 254 and contacts the upper end wall of the jack frame 11. At this time, the limiting convex corner 16 and the bevel angle 253 contact each other, and then the limiting convex corner 16 and the bevel angle 253 provide supporting force to prevent the insertion rod 22 from slipping out, which can effectively improve the stability of the insertion of the insertion rod 22 into the interior of the jack frame 11.

[0024] In a further preferred embodiment of the present invention, Figure 3 and Figure 6 As shown, the second locking assembly 26 includes a second slide groove 261, which is opened at the bottom end of the insertion rod 22, and a support plate 262 is slidably arranged inside the second slide groove 261, a second spring 263 is arranged at the top of the support plate 262, a pressing piece 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 piece 264.

[0025] In this embodiment, by setting the second spring 263, the support plate 262 is pushed downward, so that the pressing piece 264 slides downward, and the pressing piece 264 contacts the end wall of the closing cover 15 to form a snap connection, thereby further providing support 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. When subjected to high temperature, they will shrink rapidly, causing the support plate 262 to rise and the ejector 252 to shrink.

[0026] In a further preferred embodiment of the present invention, Figure 4 As shown, the closing cover 15 includes a connecting shaft 151 , which is rotatably connected to the bottom wall of the jack frame 11 , a blocking plate 152 is provided on the side wall of the connecting shaft 151 , and a torsion spring 153 is provided inside the connecting shaft 151 .

[0027] 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.

[0028] In a further preferred embodiment of the present invention, Figure 6As shown, the end of the blocking plate 152 is provided with a locking surface 154 that matches the supporting surface 265 .

[0029] 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.

[0030] 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.

[0031] 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 plate 33, so that the second shaft rod 32 pushes the arc plate 33 to rotate. Since the arc plate 33 is fixedly connected to the first shaft rod 31, the arc plate 33 pushes the first shaft rod 31 to rotate synchronously during the rotation process, and then the bevel gear set 344 cooperates with the first shaft rod 31 to drive the extension shaft rod 343 to rotate, and rotates the torsion spring 342. Since the two ends of the torsion spring 342 are respectively fixedly connected to the rotating shell 341 and the extension shaft rod 343, During the rotation of 43, the torsion spring 342 will be deflected to accumulate torque, and 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 abnormally high temperature is formed inside the connector assembly due to a connection problem, the high temperature causes the first spring 254 and the second spring 263 to contract, thereby releasing the clamping relationship between the insertion rod 22 and the jack frame 11. At this time, the torque accumulated by the torsion spring 342 drives the extension shaft 343 to rotate, and drives the first shaft 31 and the arc plate 33 to rotate, so as to achieve the effect of pushing the second shaft 32 through the arc plate 33 to make the female head assembly 2 pop out.

[0032] In a further preferred embodiment of the present invention, Figure 5 and Figure 6 As shown, the arc plate 33 includes a mounting ring 331 and an arc frame 332, the mounting ring 331 is fixedly connected to the arc frame 332, and the mounting ring 331 is fixedly connected to the first shaft rod 31, a sliding guide rail 333 is arranged inside the arc frame 332, the second shaft rod 32 is inserted into the sliding guide rail 333, and the straight-line distance between the two ends of the sliding guide rail 333 is greater than the length of the insertion rod 22.

[0033] In this embodiment, since the straight lengths at both ends of the sliding guide rail 333 are greater than the length of the insertion rod 22, when the arc 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, and the mounting ring 331 is used to fix the arc frame 332 to the first shaft rod 31.

[0034] The implementation principle of the above embodiment is as follows: the insertion rod 22 is inserted into the interior of the jack frame 11, and the closing cover 15 is pressed down, so that the closing cover 15 and the bottom wall of the jack frame 11 are in contact with each other, and the ejector 252 is pushed upward by the first spring 254, and the support plate 262 is pushed downward by the second spring 263, so that the pressing member 264 and the ejector 252 are respectively in contact with the end of the closing cover 15 and the limiting convex corner 16, thereby fixing the insertion rod 22 in the interior of the jack frame 11, and in the process of installing the insertion rod 22, the second shaft rod 32 slides inside the arc plate 33, so that the second shaft rod 32 pushes the arc plate 33 to rotate, and in the process of the arc plate 33 rotating, the extension shaft rod 343 is driven to rotate through the bevel gear set 344, and the torsion spring 342 is rotated to accumulate torque. When the temperature inside the connector component is too high due to circuit problems, the excessively high temperature causes the first spring 254 and the second spring 263 to contract, causing the pressing piece 264 and the ejecting piece 252 to retract. At this time, the locking relationship between the insertion rod 22 and the jack frame 11 is released, and the torque accumulated by the torsion spring 342 drives the extension shaft 343 to rotate, and drives the first shaft 31 and the arc plate 33 to rotate, so as to achieve the effect of pushing the second shaft 32 through the arc plate 33 to make the female head component 2 pop out, and after the female head component 2 pops out, the torsion spring 153 pushes the closing cover 15 to reset, and the closing cover 15 blocks the jack frame 11, which can effectively isolate the male head component 1 from the female head component 2, and can effectively avoid the formation of arcs between the wires at both ends, thereby improving the safety of the equipment.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
