Description

Technical Field

[0001] The present invention belongs to the technical field of connectors, and in particular relates to a coaxial connector for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source. They concentrate on the use of advanced technologies such as computers, modern sensors, information fusion, communications, artificial intelligence and automatic control. They are typical high-tech complexes. At present, the development of new energy vehicles is mainly committed to improving the safety and comfort of vehicles and providing excellent human-vehicle interaction interfaces. Therefore, new energy vehicles need to rely on a large number of high-frequency signal transmissions (such as sensors, cameras, radars, communication modules, etc.). Due to the advantages of high-frequency transmission, anti-interference, high bandwidth and high reliability, coaxial connectors have become an indispensable component in new energy vehicles and are widely used in various fields of new energy vehicles, especially in key areas such as power systems, battery management systems and on-board electronic equipment.

[0003] Patent document CN220856983U disclosed a new energy vehicle coaxial connector, including an insulating rubber core and an outer conductor wrapped outside the rubber core, the outer conductor is L-shaped, one end is a cylindrical connection part, and the other end is a semi-open crimping part, the insulating rubber core is placed at the L-shaped corner of the outer conductor, and one end to the other end are the first connection section, the limit section and the second connection section, the side wall of the first connection section is provided with a through hole allowing the mating terminal to be inserted, the through hole is coaxially arranged with the cylindrical connection part of the outer conductor, the inside of the insulating rubber core is provided with a cavity connecting the end face and the through hole of the second connection section, the limit section is an annular groove body provided on the outer wall of the insulating rubber core, and the side wall of the outer conductor is provided with an inwardly concave limit part corresponding to the annular groove body, and after the insulating rubber core and the outer conductor are assembled, the limit part is embedded in the annular groove body. The patent provides a new energy vehicle coaxial connector, which realizes the stable assembly of the insulating rubber core and the outer conductor to prevent displacement or falling off in the subsequent realization.

[0004] The above patent documents use a variety of structural combinations to achieve a stable assembly of the rubber core and the outer conductor. Although the overall stability of the connector is improved and its service life is extended, due to the widespread use of coaxial connectors in new energy vehicles, the coaxial connector has gradually developed from the initial single-pin single-hole insertion to the multi-pin multi-hole direction. With the widespread use of new energy vehicles, the actual road conditions of new energy vehicles have also changed. For the initial flat road conditions, it is only necessary to insert the pin into the jack and attach a certain threaded connection or tapered connection. However, if the new energy vehicle continues to travel on bumpy roads, the bumps will cause vibrations, and the threaded connection or tapered connection will loosen, which may cause the internal contact points of the connector to loosen, resulting in unstable signals or power outages, and complex road conditions may generate a large amount of dust or water vapor. That is to say, in the prior art, when new energy vehicles are bumpy on complex road conditions, it is easy for the connector joint to loosen, and the male head of the connector is often a multi-pin structure. After loosening, short circuits are likely to occur, affecting the use of the car; at the same time, when the male and female heads of the coaxial connector are separated, external dust or water vapor can easily enter the interior of the coaxial connector, and long-term accumulation will affect the performance of the coaxial connector.

[0053] A fixed mounting plate 110 is disposed in the middle of the connector female head 100. In new energy vehicles, the fixed mounting plate 110 is fixedly connected by a structural member and usually does not move.

[0054] The male connector 200 further includes a male housing 220 , the outer diameter of which is greater than the outer diameter of the coaxial cable 300 , and the specification of the pin 210 corresponds to the specification of the socket 101 .

[0055] The fixed seat assembly 400 includes a fixed cylinder 410, a first end cover 420, a second end cover 430 and a first spring 460. The first end cover 420 and the second end cover 430 are fixedly connected to the two ends of the fixed cylinder 410 respectively. The first end cover 420 and the fixed mounting plate 110 are connected by bolts. One end of the first spring 460 is connected to the second end cover 430, and the other end is connected to the movable seat assembly 500. The first air pipe 440 and the second air pipe 450 are arranged on the outer periphery of the fixed cylinder 410. Valves (not shown in the figure) are arranged on the first air pipe 440 and the second air pipe 450.

[0056] A first groove 411 is provided on the outer periphery of the fixing cylinder 410 , a first through hole 421 is provided on the first end cover 420 , a second groove 431 is provided on the second end cover 430 , and the second groove 431 is a U-shaped groove. The connector female head 100 passes through the first through hole 421 , and the coaxial cable 300 is engaged in the second groove 431 .

[0057] The movable seat assembly 500 includes a first piston 510, a piston connecting rod 520, a second piston 530 and a piston connecting rod extension end 540. The first piston 510 and the second piston 530 are respectively connected to the two ends of the piston connecting rod 520.

A semicircular hole 541, a semicircular groove 542 and a third groove 543 are provided on the piston connecting rod extension end 540. An area A is formed between the connector female head 100, the fixed cylinder 410, the first end cover 420 and the first piston 510. An area B is formed between the first piston 510, the piston connecting rod 520, the second piston 530 and the fixed cylinder 410. The first air pipe 440 is connected to the area A, and the second air pipe 450 is connected to the area B.

[0058] It should be noted that during initial assembly, if the Figure 2 As shown, the first spring 460 is in a free state, at which time the gas pressures in area A and area B are equal (greater than atmospheric pressure). Fig. 9 As shown in FIG. 1 , the valve on the first air pipe 440 is opened to connect the gas in area A to the atmosphere, and the movable seat assembly 500 moves to the right. At this time, the first spring 460 is in a stretched state. When the first spring 460 and the movable seat assembly 500 are in a balanced state, the pin 210 is completely inserted into the socket 101. When the pin 210 needs to be completely removed from the socket 101, as shown in FIG. Figure 8 As shown, high-pressure gas is injected into area A, the movable seat assembly 500 moves to the left, and the first spring 460 is first restored and then compressed. When the leftmost end of the movable seat assembly 500 abuts against the second end cover 430, the first spring 460 and the movable seat assembly 500 are in a balanced state, and the pin 210 is completely separated from the socket 101.

[0059] The blocking assembly 600 includes a first blocking block 610, a second blocking block 620, a third blocking block 630 and a handle 640.

When the first spring 460 is compressed to the extreme position, the first blocking block 610 is located at the top of the coaxial cable 300 and engages with it, the second blocking block 620 is located at the top of the male connector shell 220 and engages with it, and the third blocking block 630 is located at the top of the pin 210 and extends into the interior of the third groove 543.

[0060] It is not difficult to understand that when the pin 210 is disengaged from the socket 101, the blocking assembly 600 needs to be engaged with the fixing seat assembly 400 to prevent dust and other impurities from falling in.

[0061] The telescopic assembly 700 includes a box body 710, a third end cover 720, a fourth end cover 730, a second spring 740 and a third piston rod assembly 750. The two ends of the box body 710 are respectively connected to the third end cover 720 and the fourth end cover 730, which are connected to the third end cover 720 through a support (not shown in the figure) to ensure that the two telescopic assemblies 700 are limited. The third piston rod assembly 750 passes through the fourth end cover 730, and the second spring 740 is located inside the box body 710. One end of the second spring 740 is connected to the fourth end cover 730, and the other end is connected to the third piston rod assembly 750. A third air pipe 760 and a fourth air pipe 770 are also provided on the box body 710. Both the third air pipe 760 and the fourth air pipe 770 are provided with valves (not shown in the figure). An area C is formed between the box body 710, the third end cover 720 and the third piston rod assembly 750. An area D is formed between the box body 710, the fourth end cover 730 and the third piston rod assembly 750. The third air pipe 760 is connected to the area C, and the fourth air pipe 770 is connected to the area D.

[0062] The axial fixing assembly 900 includes a follower frame 910, a U-shaped fixing plate 920 and a rotating plate 930. The U-shaped fixing plate 920 is respectively connected to the follower frame 910 and the rotating plate 930. A fourth groove 911 is provided on the inner wall of the follower frame 910. A fifth groove 931 is provided in the middle of the rotating plate 930. Second through holes 932 are provided at both ends of the fifth groove 931. The rotating plate 930 is connected to the third piston rod assembly 750 by bolts.

[0063] The support assembly 800 includes a fixed frame 810, a support connecting rod 820 and a connecting head 830. The two ends of the support connecting rod 820 are fixedly connected to the fixed frame 810 and the connecting head 830 respectively. The connecting head 830 is rotatably connected to the rotating plate 930 by bolts. The fixed frame 810 is usually fixed by a support (not shown in the figure).

[0064] It should be noted that, refer to the attached Fig.11 and attached Fig.13 The follower frame 910 and the U-shaped fixing plate 920 are integrally formed or welded, and although the rotating plate 930 and the U-shaped fixing plate 920 are connected by bolts, in practice, the relative positions of the rotating plate 930 and the U-shaped fixing plate 920 are fixed. Since the present invention compresses the coaxial cable 300 by two cable compressing components, it is necessary to perform initial calibration when determining the relative position. During the initial calibration, the coaxial cable 300 is compressed by the two cable compressing components, as shown in the attached Fig.13 As shown, the follower frame 910 is in a vertical state at this time. If it is not vertical, the bolts between the rotating plate 930 and the U-shaped fixing plate 920 can be loosened to make the follower frame 910 in a vertical state and then locked. That is to say, when the air pressure in area C and area D of the telescopic assembly 700 is equal, as shown in the attached Fig.11As shown in FIG. 1 , the follower frame 910 is in a non-vertical state. In practice, the distance between the follower frame 910 and the coaxial cable 300 is small, that is, the coaxial cable 300 is close to the follower frame 910. Fig.11 and attached Fig.13 The actual deflection angle of the middle rotating plate 930 is relatively small, generally between 5-8 degrees. In order to ensure that the follower frame 910 does not interfere with the coaxial cable 300 during the recovery process, a fourth groove 911 is usually provided on the lower half of the inner wall of the follower frame 910 .

[0065] The present invention also provides a method for using a coaxial connector for a new energy vehicle, the method comprising a method S1 for firmly connecting a pin, a method S2 for placing the pin after it is loosened, and a method S3 for fixing a coaxial cable;

[0066] The method S1 of firmly connecting the pins comprises the following steps:

[0067] S11, opening the valve on the first air pipe 440, connecting the gas in the area A with the atmosphere through the first air pipe 440, and at this time the movable seat assembly 500 moves to the right;

[0068] S12, the male housing 220 engaged in the semicircular groove 542 drives the plug pin 210 to move rightward, and the plug pin 210 enters the corresponding plug hole 101;

[0069] S13, at this time, the first spring 460 is stretched, and when the first spring 460 and the movable seat assembly 500 reach a balance, the pin 210 is completely inserted into the socket 101;

[0070] The method S2 for placing the pin after it is released comprises the following steps:

[0071] S21, opening the valve on the first air pipe 440, continuously increasing the pressure into the area A through the first air pipe 440 to a preset value and stopping the air intake, at which time the movable seat assembly 500 moves to the left;

[0072] S22, the male housing 220 engaged in the semicircular groove 542 drives the plug pin 210 to move to the left, and the plug pin 210 is gradually separated from the socket 101;

[0073] S23, the first spring 460 is first restored and then compressed, and when the leftmost end of the movable seat assembly 500 abuts against the second end cover 430, the first spring 460 and the movable seat assembly 500 are in a balanced state, and the pin 210 is completely separated from the socket 101;

[0074] S24, engaging the blocking assembly 600 with the fixing seat assembly 400 to prevent dust and other impurities from falling in;

[0075] The method S3 wherein the coaxial cable is fixed comprises the following steps:

[0076] S31, opening the valves of the two third air pipes 760, and simultaneously increasing the pressure in the areas C of the two telescopic assemblies 700 through the third air pipes 760, so that the second spring 740 is compressed and the third piston rod assembly 750 extends outward;

[0077] S32, the rotating plate 930 deflects, driving the follower frames 910 to deflect, so that the two follower frames 910 abut against the coaxial cable 300, and the coaxial cable 300 is fixed.
