[0002] In the field of new energy vehicles, three-way connecting plugs are usually used to connect multiple electrical devices or lines to achieve signal or power distribution. Currently, there are many types of three-way connecting plugs on the market, which can already meet the signal or power distribution in the field of new energy vehicles.

[0003] However, there are also some shortcomings. For example, the three-way connecting plug is generally connected by a snap-on method when plugging in, that is, an anti-detachment block is provided on the three-way connector, and a snap ring is provided on the plug connector. When the plug connector is plugged into the three-way connector, the snap ring can be stuck on the block. During subsequent disassembly, a flat-blade screwdriver is required to lift the snap ring and disengage it from the snap before the plug connector can be pulled out of the three-way connector.

[0004] With this buckle structure design, after the snap ring is lifted up multiple times, there is a possibility that the snap ring will be deformed and damaged, and lose its snapping function. At the same time, when using a flat-blade screwdriver to lift the snap ring, there is a problem that the flat-blade screwdriver is difficult to extend to the bottom of the snap ring, that is, the flat-blade screwdriver is difficult to effectively lift the snap ring, and brute force must be used to insert it into the bottom of the snap ring, which can easily squeeze and damage the snap ring. In severe cases, the flat-blade screwdriver slips off the snap ring and injures the hand.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] Reference Figure 1 - Fig. 9 , a three-way automobile connection plug, comprising a connector 1 with three ports, and a plug connector 2 adapted to the three ports of the connector 1;

[0040] One end of each of the plug connectors 2 is connected to a wire 3, and the other end of the plug connector 2 is inserted into a port of the connector 1;

[0041] The upper and lower surfaces of the other end of each plug connector 2 are provided with a plug plate 4, and the outer surface of the end of the plug plate 4 is provided with a pull pin 5;

[0042] The upper and lower surfaces of the three ports of the connector 1 are provided with recesses 6 adapted to the plug plate 4. The upper and lower surfaces of the middle position of the connector 1 are rotatably connected with a swivel 7. The outer circle of the swivel 7 is provided with three hooks 8 pointing in the same direction.

[0043] The plug connector 2 is inserted into the port of the connector 1, the plug plate 4 slides into the recess 6, the swivel 7 is rotated, and the hook 8 hooks the pull pin 5;

[0044] In this embodiment, the plug connector 2 is plugged into the connector 1, and the specific process is as follows:

[0045] Place the other end of the plug connector 2 opposite to the port of the connector 1, and at the same time, the two plug plates 4 on the plug connector 2 are opposite to the recess 6 on the port of the connector 1, the plug connector 2 is inserted into the port of the connector 1, and the plug plates 4 are embedded in the recess 6, and then the swivel 7 is rotated, and the swivel 7 drives the hook body 8 to rotate. Each hook body 8 is set in a wedge shape, and the tip of the hook body 8 will rotate to the back of the pull pin 5, that is, the pull pin 5 is located between the swivel 7 and the hook body 8, and the outer surface of the pull pin 5 is pressed against the inner wall of the hook body 8. At this time, continue to rotate the hook body 8, and the hook body 8 will apply an extrusion force to the pull pin 5 in the direction of the swivel 7, so that the plug connector 2 can be pulled toward the center of the connector 1, and the hook body 8 provides a continuous extrusion force on the pull pin 5 to ensure the stability between the plug connector 2 and the connector 1;

[0046] In summary, the three-way automobile connection plug designed in this embodiment does not use the clamping structure of the clamping block and the clamping ring in the prior art, which directly avoids the problem of the clamping ring being lifted and damaged, or hurting the hand, and the hook body 8 cooperates with the pull pin 5, the hook body 8 hooks the pull pin 5, and the plug connector 2 is hooked on the connector 1;

[0047] During the whole plugging process, it is only necessary to install the three plug connectors 2 in place, rotate the swivel 7, and the swivel 7 will synchronously drive the three hook bodies 8 to squeeze the pull pin 5 together, so that the three plug connectors 2 can be quickly stabilized. Similarly, when the three plug connectors 2 are pulled out, the swivel 7 is reversed and the hook body 8 is separated from the pull pin 5, so that the three plug connectors 2 can be quickly pulled out, which is convenient for maintenance personnel to operate;

[0048] The three plug connectors 2 can be quickly unplugged, which can achieve high efficiency and labor saving, and the electrical modules connected to the three plug connectors 2 can be tested. The structure is simple and light, the installation efficiency is high, and the use environment compatibility is strong, especially in the scene where frequent plugging and unplugging is required, such as the maintenance scene of new energy vehicles;

[0049] In order to ensure the stability of the swivel 7, the upper and lower surfaces of the connector 1 are threadedly connected with fastening bolts 71, and the fastening bolts 71 are arranged through the swivel 7. When the fastening bolts 71 are loosened, the swivel 7 can be flexibly rotated. After the swivel 7 is rotated into place, the fastening bolts 71 can be tightened, and the fastening bolts 71 squeeze and fasten the swivel 7 to the connector 1.

[0050] Reference Figure 1 - Figure 4 Each of the pull pins 5 is slidably connected to the plug plate 4; the upper and lower surfaces of the three ports of each of the connectors 1 are provided with fixing holes 9 adapted to the pull pins 5, and the fixing holes 9 are arranged in the recess 6 and close to the center of the connector 1;

[0051] When the connector 1 and the plug connector 2 are plugged in and matched, it is necessary to test whether the connection is connected. In order to facilitate multiple tests, the plug connector 2 can be pre-plugged into the connector 1, that is, the pull pin 5 designed in this embodiment cooperates with the fixing hole 9, so that the plug connector 2 and the connector 1 can be pre-plugged; the pull pin 5 is plugged in the fixing hole 9, and the depth of the fixing hole 9 is small, which is convenient for the detachment of the pull pin 5. The plug connector 2 can be pulled out of the fixing hole 9 by pulling the pull pin 5 hard, for example, it can be pulled out with a force of one Newton or two Newtons. In the absence of external force, the pull pin 5 cooperates with the fixing hole 9 to ensure the pre-plugging of the plug connector 2 and the connector 1. At this time, the maintenance personnel can let go of the three-way automobile connection plug and operate other links for testing.

[0052] Reference Figure 1 - Figure 5 A notch 10 adapted to the pull pin 5 is formed on the inner side of each hook body 8, the hook body 8 hooks the pull pin 5, and the outer ring of the pull pin 5 is embedded in the notch 10;

[0053] The swivel 7 drives the hook body 8 to rotate, and the hook body 8 is pressed on the pull pin 5. When the hook body 8 is rotated into place, the notch 10 on the inner wall of the hook body 8 is opposite to the pull pin 5, and the pull pin 5 is embedded in the notch 10, which constrains the relative movement between the pull pin 5 and the hook body 8, thereby stabilizing the separation trend between the plug connector 2 and the connector 1, thereby improving the plug-in stability between the plug connector 2 and the connector 1. The notch 10 cooperates with the pull pin 5 to assist the fastening bolt 71, which assists the fastening bolt 71 in locking the swivel 7. Because the vehicle is bumpy during driving, the fastening bolt 71 will become loose.

[0054] Reference Figure 1 - Figure 5 , an elastic rod 11 is provided on the outer surface of each hook body 8, one end of each elastic rod 11 is fixed to the surface of the hook body 8, and the other end of each elastic rod 11 extends along the position of the notch 10, the outer ring of the pull pin 5 is embedded in the notch 10, and the surface of the elastic rod 11 is pressed on the pull pin 5;

[0055] An elastic rod 11 is provided on the hook body 8, one end of the elastic rod 11 can be fixed to the hook body 8 by a flat head self-tapping screw, the elastic rod 11 is loosened, the angle of the elastic rod 11 is adjusted, and the extrusion force of the elastic rod 11 on the pull pin 5 is adjusted;

[0056] When the pull pin 5 slides into the notch 10, the surface of the pull pin 5 is squeezed on the elastic rod 11, and then the pull pin 5 slides into the notch 10. At this time, the hook body 8 squeezes the pull pin 5, and the elastic rod 11 squeezes the pull pin 5, which can further improve the stability between the pull pin 5 and the hook body 8.

[0057] Reference Figure 1 - Figure 5 A reinforcing rod 12 is provided between the two hook bodies 8, the reinforcing rod 12 is arranged away from the tip of the hook body 8, and both ends of the reinforcing rod 12 are vertically fixed to the inner wall of the hook body 8;

[0058] A magnetic plate 13 is provided on one side of the outer surface of the three ports of the connector 1, and the magnetic plate 13 can absorb the reinforcing rod 12;

[0059] In this embodiment, the reinforcing rod 12 is designed to connect the two swivels 7 into a whole, that is, by rotating the hook body 8, all the hook bodies 8 can be driven to rotate synchronously, which is convenient for the rotation operation of the hook body 8; on the other hand, the swivels 7 are connected as a whole, which improves the extrusion stability of the hook body 8 on the pull pin 5 and reduces the deformation of the hook body 8 when the pull pin 5 is extruded, so that the hook body 8 can stably extrude the pull pin 5; further, in the process of executing the operation of plugging the plug connector 2 into the connector 1, in order to prevent the hook body 8 from rotating by itself and interfering with the plugging of the plug connector 2, a magnetic plate 13 is provided for this purpose. The magnetic plate 13 can absorb the reinforcing rod 12, and the swivel 7 is rotated so that the reinforcing rod 12 is attached to the magnetic plate 13, and the swivel 7 and the hook body 8 are adsorbed and fixed. At this time, there are no obstacles at the three ports of the connector 1 to hinder the plugging of the plug connector 2.

[0060] Reference Figure 1 - Fig. 9 The other side of the outer surface of the three ports of the connector 1 is provided with a clamping claw 14, and the clamping claw 14 can clamp the reinforcing rod 12;

[0061] After the hook body 8 rotates and squeezes on the pull pin 5 and rotates into position, the reinforcing rod 12 can be moved from the position of the magnetic plate 13 to the inside of the clamping jaw 14. The clamping force of the clamping jaw 14 can stably clamp the reinforcing rod 12. The reinforcing rod 12 is clamped, which naturally stabilizes the relative rotation between the hook body 8 and the swivel 7 and the connector 1, further improving the stability of the hook body 8, thereby improving the squeezing stability of the hook body 8 on the pull pin 5, and then improving the plug-in stability between the plug connector 2 and the connector 1.

[0062] Reference Figure 1 - Fig. 9 Each of the clamping jaws 14 is provided with a plug hole 15, and the plug holes 15 are respectively arranged along the length direction of the three ports of the connector 1;

[0063] Each of the reinforcing rods 12 is provided with a through hole 16, which is radially opened along the reinforcing rod 12, and a plug rod 17 is provided in the through hole 16, the end of the plug rod 17 is fixedly connected to a side wall of the outer surface of the plug connector 2, and the plug rod 17 is arranged along the axial direction of the through hole 16;

[0064] In this embodiment, the plug-in movement process of the plug connector 2 is divided into two strokes. The first stroke is that the plug connector 2 is plugged into the port of the connector 1, and the plug rod 17 is inserted into the outer plug hole 15 of the clamping jaw 14, that is, it is inserted into the part of the plug hole 15 close to the plug connector 2. At this time, the end of the plug rod 17 is not inserted into the clamping jaw 14, and then the hook body 8 is rotated. The inner wall of the tip of the hook body 8 is squeezed on the pull pin 5, and the reinforcing rod 12 is located at the outer side of the clamping jaw 14. At this time, the hook body 8 is rotated again with force, and the reinforcing rod 12 is embedded in the clamping jaw 14. At the same time, the inner wall of the hook body 8 squeezes the pull pin 5 again, forcing the pull pin 5 to move toward the center position of the connector 1. The pull pin 5 drives the plug connector 2 to move through the plug plate 4. At this time, the plug connector 2 performs the second stroke, and the plug connector 2 is completely plugged into the port of the connector 1. Fig. 9 As shown, the end of the insertion rod 17 is inserted into the through hole 16 on the reinforcing rod 12, and the insertion rod 17 locks the reinforcing rod 12 in the clamping claw 14. The insertion rod 17, the clamping claw 14 and the reinforcing rod 12 form a self-locking structure, which further improves the plug-in stability of the plug connector 2 and the connector 1;

[0065] When it is necessary to remove the plug connector 2 from the connector 1, the specific operation process is to pull out the plug connector 2 with force, and at the same time, rotate the hook body 8 in the opposite direction with force, so that the end of the plug rod 17 disengages from the through hole 16 on the reinforcing rod 12, and the through hole 16 on the reinforcing rod 12 squeezes the end of the plug rod 17, and the end of the plug rod 17 is slightly deformed, so that the plug rod 17 can be disengaged from the through hole 16, and the reinforcing rod 12 can be easily disengaged from the clamping claw 14. In order to facilitate the plug-in and disengagement from the through hole 16, the through hole 16 on the reinforcing rod 12 and the plug rod 17 can be set to a clearance fit, and there is a clearance between the plug rod 17 and the through hole 16, so that the plug-in end can be easily disengaged from the through hole 16, and no greater force is required to disassemble the three-way automobile connecting plug.

[0066] Reference Figure 1 - Fig. 9 , a pull rod 19 connected to a tension spring 18 is provided on the outer side wall of each of the swivels 7, and the end of the pull rod 19 is bent into a hook shape;

[0067] After the plug connector 2 is plugged into the connector 1 and the first stroke is performed, the hook portion of the pull rod 19 is directly hooked on the pull pin 5, and the hook portion of the pull rod 19 is attached to the outer surface of the plug plate 4, and then the second stroke of the plug connector 2 is performed, the swivel 7 rotates and pulls the pull rod 19 through the tension spring 18, as shown in FIG. Figure 8 As shown, the pull rod 19 pulls the pull pin 5, and applies a pulling force toward the center of the connector 1 to the pull pin 5 again, thereby improving the stability between the plug connector 2 and the connector 1 again.

[0068] Reference Figure 1 - Figure 3 , a reinforcement block 20 is provided at the end of each of the plugboards 4, and the reinforcement block 20 is fixedly connected to the plugboard 4;

[0069] A reinforcing block 20 is provided at the end of the plug plate 4 to improve the strength of the end of the plug plate 4. The purpose is to improve the stability of the pull pin 5. The pull pin 5 is squeezed by the hook body 8 and is pulled and tilted. If the pull pin 5 tilts too much, the hook body 8 will lose the squeezing force on the pull pin 5. For this reason, the reinforcing block 20 is provided.

[0070] Reference Figure 1 - Figure 3 The other end of each plug connector 2 is provided with an annular sealing groove 21; the outer surfaces of the three ports of the connector 1 are provided with stepped grooves 22;

[0071] The sealing groove 21 provided on the plug connector 2 cooperates with the port of the connector 1, and the inner wall of the sealing groove 21 is attached to the surface of the stepped groove 22, which can improve the plug-in sealing between the plug connector 2 and the connector 1, reduce the possibility of external dust penetrating into the interior, protect the three-way automobile connection plug, and extend its service life.

[0072] Working principle:

[0073] The plugging process of the three-way automobile connection plug is as follows: the plugging movement process of the plug connector 2 is divided into two strokes. The first stroke is that the plug connector 2 is plugged into the port of the connector 1, the plug plate 4 is embedded in the recess 6, and the plug rod 17 is inserted into the plug hole 15 outside the clamping claw 14, that is, it is inserted into the part of the plug hole 15 close to the plug connector 2. At this time, the end of the plug rod 17 is not inserted into the clamping jaw 14, and then the hook body 8 is rotated, and the inner side wall of the tip of the hook body 8 is squeezed on the pull pin 5, and the reinforcing rod 12 is located The outer side of the clamping jaw 14, the hook body 8 is rotated forcefully at this time, the reinforcing rod 12 is embedded in the clamping jaw 14, and at the same time, the inner side wall of the hook body 8 squeezes the pull pin 5 again, forcing the pull pin 5 to move toward the center of the connector 1, and the pull pin 5 drives the plug connector 2 to move through the plug plate 4. At this time, the plug connector 2 performs the second stroke, and the plug connector 2 is completely plugged into the port of the connector 1. The end of the plug rod 17 is inserted into the through hole 16 on the reinforcing rod 12, and the plug rod 17 locks the reinforcing rod 12 in the clamping jaw 14;

[0074] The disassembly process of the three-way automobile connecting plug is as follows: pull out the plug connector 2 with force, and at the same time rotate the hook body 8 in the opposite direction with force, so that the end of the plug rod 17 is separated from the through hole 16 on the reinforcing rod 12, and the through hole 16 on the reinforcing rod 12 squeezes the end of the plug rod 17, and the end of the plug rod 17 is slightly deformed, so that the plug rod 17 can be separated from the through hole 16, the reinforcing rod 12 is separated from the clamping claw 14, the reinforcing rod 12 is adsorbed on the magnetic plate 13, and the plug connector 2 is separated from the port of the connector 1.
