Description

Technical Field

[0001] This invention relates to the field of automotive connector technology, and in particular to an interlocking connector with a fixed position. Background Technology

[0002] Wire harness connectors are common components used for wiring connections in automobiles. A wire harness connector is a type of terminal consisting of a plug and a socket. Currently, with the increasing functionality of automobiles, wire harness connectors are usually installed in automobiles. Most existing automobiles have multiple port connectors on the circuit board integrated circuit, which are then connected through wire harness connectors. However, with integration, modular connectors have become a faster and more convenient way to connect wire harnesses.

[0003] In order to prevent the wire harness from falling off during vehicle operation, existing integrated wiring harness connectors generally use a locking mechanism to engage the plug and socket. While this method does prevent detachment during use, over a long period of use, including vibrations during vehicle operation, friction can occur between the plug and socket, causing wear between the contact plates. In addition, the contact gaps between the plug and socket can be affected by changes in ambient temperature, leading to aging. This reduces the waterproof performance between the plug and socket, causing the connecting pins to loosen or even corrode, resulting in poor contact and affecting the normal use of the vehicle. Summary of the Invention

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. By setting a female end sleeve, the present invention can wrap the power wiring part and the signal wiring part, and both the signal wiring end and the power wiring end are inserted into the connector sleeve, which can achieve multi-layer isolation, improve the stability of the seal, and the internal space can play a role in heat preservation, reducing the direct interference of temperature difference on the internal environment and reducing the generation of gaps.

[0022] 2. By setting a fixed wiring part, the pressure formed by squeezing the female end sleeve and the fixed wiring part can firmly fix the female end sleeve and the fixed wiring part, which improves the connection strength and keeps the gap in a sealed state. This reduces the retention of moisture in the gap and avoids corrosion of the pins. Moreover, the air pressure circulation can improve the tightness and improve the seepage prevention.

[0023] 3. The present invention forms a drainage channel by rolling up the outer end of the isolation protrusion, which can block the water on the surface of the sealing sleeve. When the water hanging on the sealing sleeve falls under the force of gravity, it is dispersed into the drainage channel formed by the rolling up outer end of the multiple isolation protrusions. When the isolation protrusions and the soft pleats are in a state of communication, they can form a water receiving part around the periphery of the sealing sleeve, so that the water hanging in the gap of the soft pleats can flow into the drainage channel. Furthermore, a reinforcing part is formed on the outside of the isolation protrusions, which can form an isolation layer. During the vibration process, the reinforcing part can prevent water from splashing. An external seepage hole is provided near the strip groove.

[0024] 4. When the connector pin is fully inserted into the wiring hole, it will contact the guide slope, which can separate the two branch conductors and allow them to be clamped by the branch conductors. After the connector pin is clamped, when it moves to the guide ball in the slide groove, the guide ball can drive the rocker arm to move upward at one end of the slide groove, and then the other end of the rocker arm moves downward. In this way, the other end of the rocker arm drives the locking ball to move to the bottom of the locking groove cavity, which is a combination of trapezoidal and rectangular shapes. In this way, the locking ball can move to one side of the branch conductor under the action of the slope, thereby forming a locked state and preventing vibration from causing poor contact.

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] Reference Figures 1 to 3This embodiment provides an interlocking connector with a fixed position, including a fixed wiring portion 2 disposed on a circuit board 1. The fixed wiring portion 2 is provided with a support foot formed by a threaded sleeve, which is fixed to the circuit board 1 by bolts. A height space 8 is formed between the fixed wiring portion 2 and the circuit board 1. The height space 8 is used to prevent electrical components on the circuit board 1 from being damaged, thus forming a protective state for the electrical components. The fixed wiring portion 2 includes a fixed base 21, on which a connecting foot 22 electrically connected to the circuit board 1 is provided. The connecting foot 22 includes, but is not limited to, square needle-shaped, strip-shaped, and springboard-shaped. A strip groove 24 is provided at segment a, running along its inner wall. The strip groove 24 expands outward to form a columnar space to increase the contact area, thereby protecting segment a and preventing external water from seeping into the interior of the female end sleeve 3. An external venting cavity 29 is provided inside the connector sleeve 10 of the fixed base 21. The space of the external venting cavity 29 is in communication with the sealing groove 23. Furthermore, it is isolated by the flexible silicone layer 28 to form a sealed state, and the first locking mechanism 27 and the second locking mechanism 25 are located on the periphery of the external exhaust flow cavity 29 and are sealed in the external exhaust flow cavity 29 by the flexible silicone layer 28. The function of the flexible silicone layer 28 is to prevent the air pressure in the external exhaust flow cavity 29 from dissipating and to make it accumulate. In addition, through the change of air pressure in the external exhaust flow cavity 29, the air pressure can achieve a pressure expansion state on the flexible silicone layer 28, which can achieve the purpose of tightly fitting the inner wall of the female end sleeve 3, thus improving the sealing performance. The flexible silicone layer 28 can also limit the first locking mechanism 27 and the second locking mechanism 25. When the fixed wiring part 2 is separated from the female end sleeve 3, the flexible silicone layer 28 can also reset the first locking mechanism 27 and the second locking mechanism 25 into the external exhaust flow cavity 29. The surface of the flexible silicone layer 28 is smooth, which can form a sealed fitting surface when it is tightly fitted to the inner wall of the female end sleeve 3, thus preventing external moisture from penetrating into the female end sleeve 3.

[0042] The first locking mechanism 27 and the second locking mechanism 25 form a segment b fitting point, and the sealing groove 23 located between the first locking mechanism 27 and the second locking mechanism 25 and the segment b fitting point form a connecting segment a fitting point;

[0043] A first locking mechanism 27 is provided within the sealing groove 23 and along the periphery of the left-side connector sleeve 10. The first locking mechanism 27 includes a lever 271, a U-shaped member 273, and a built-in reset lever 275. A guide groove 272 is provided at the top of the lever 271. When the guide groove 272 contacts the guide rod 346 on the female end sleeve 3, under the action of pressing pressure, the guide rod 346 causes the guide groove 272 on the lever 271 to be squeezed. The insertion end 2710 on the lever 271 moves into the outer extrusion groove 279. When the inner wall of the outer extrusion groove 279 is squeezed, it can move the U-shaped member 273 towards segment b. One end of the lever 271 is provided with an insertion end 2710, which is sleeved in the outer extrusion groove 279 opened at the end of the U-shaped member 273. A bead opening 274 is provided on one side of the inner wall of the U-shaped member 273. The built-in reset lever 275 is connected to... The adhesive layer 277 is fixedly connected to the inner wall of the U-shaped part 273. Both ends of the built-in reset rod 275 are fixedly connected to the fixing blocks 2761 by elastic strips 276. The fixing blocks 2761 are provided with balls 278. Then the ball openings 274 on the U-shaped part 273 move towards the balls 278. Since the ball openings 274 are set to open inward, the balls 278 and the insertion end 2710 are squeezed together. As the U-shaped part 273 moves towards segment b, the side of the U-shaped part 273 located at the insertion end 2710 expands outward. This allows the outer side of the U-shaped part 273 to completely fit against the inner wall of the female end sleeve 3 and form a squeezing state. This can squeeze and limit the inner wall part of the female end sleeve 3 located at the power terminal 5. The connecting adhesive layer 277 and elastic strips 276 can help the U-shaped part 273 to reset quickly.

[0044] A second locking mechanism 25 is provided within the sealing groove 23 and along the periphery of the two right-side connector sleeves 10. The second locking mechanism 25 includes an elastic element 251. Both sides of the elastic element 251 have inner openings 252. An outer sliding strip 254 is fitted inside the inner openings 252. Both ends of the elastic element 251 have guide notches 253. An elliptical bead 255 is provided between the inner openings 252 and the outer sliding strip 254. Both ends of the elliptical bead 255 are fitted into limiting openings on the inner wall of the inner opening 252 and the outer sliding strip 254. The guide rod 346 and the guide notch 25... After contact, the elastic element 251 moves to segment b on the other side. During the movement of the elastic element 251, the elliptical bead 255 is squeezed by the inner wall of the limiting port on the inner wall of the inner constriction 252, and the elliptical bead 255 is set at an angle. In this way, the elliptical bead 255 can drive the outer moving strip 254 to expand outward. In this way, the outer moving strips 254 on both sides can form an independent squeezing action, and then the outer moving strip 254 and the elastic element 251 can be tightly attached to the inner wall of the female end sleeve 3. This can achieve a sealed state for the sealing groove 23 located at the signal terminal 4.

[0045] In use, first, place the bottom end of the female end sleeve 3 onto the sealing groove 23. Then, when pressing down on the signal terminal 4 and the source terminal 5, the guide rod 346 is simultaneously squeezed along with the guide notch 253 and the guide groove 272 on the lever 271. At this time, the insertion end 2710 on the lever 271 moves into the outward extrusion groove 279. When the inner wall of the outward extrusion groove 279 is squeezed, the U-shaped part 273 moves towards section b. The ball 278 and the insertion end 2710 are squeezed together. As the U-shaped part 273 moves towards section b, the side of the U-shaped part 273 located at the insertion end 2710 expands outward, so that the outer side of the U-shaped part 273 can completely fit against the female end sleeve. On the inner wall of the power terminal 3, a compression state is formed, which can compress and limit the inner wall of the female end sleeve 3 located at the power terminal 5. At the same time, the elastic element 251 moves to the other side of segment b. During the movement of the elastic element 251, the elliptical bead 255 is compressed by the inner wall of the limiting port on the inner wall of the inner opening 252, and the elliptical bead 255 is set at an angle. In this way, the elliptical bead 255 can drive the outer moving strip 254 to expand outward. In this way, the outer moving strips 254 on both sides can form an independent compression action, and the outer moving strip 254 and the elastic element 251 can be tightly attached to the inner wall of the female end sleeve 3, so that the sealing groove 23 located at the signal terminal 4 can be sealed.

[0046] Example 2

[0047] Reference Figures 4 to 7 This embodiment includes all the features of Embodiment 1, with the distinguishing feature being that a female end sleeve 3 is wrapped around the power terminal 5 and the signal terminal 4, and the female end sleeve 3 is inserted into the sealing groove 23 provided on the fixed wiring part 2; the power terminal 5 is used to connect to the power supply, and the signal terminal 4 is connected to the electrical components; the female end sleeve 3 includes a sealing sleeve 31 that is adapted to the shape of the sealing groove 23, and a locking foot part 34 is provided at the bottom end of the sealing sleeve 31. The locking foot part 34 is inserted into the sealing groove 23, and the locking foot part 34 includes a B section adapted to the b section and an A section adapted to the a section; the female end sleeve 3 also includes a compression part 32, which can extend and retract in the height direction. During the initial installation, the compression part 32 is in an extended and retracted state. The purpose of this setting is to ensure that the locking foot part 34 is inserted into the sealing groove 23 first, and to ensure that the sliding plug part 7 is pre-inserted into the connector sleeve 10, forming a state of compressing the gas inside the connector sleeve 10. The compression part 32 is fixedly connected to the top of the sealing sleeve 31. The compression part 32 is fixedly connected to the outer wall of the wiring part 6 through the through hole provided on the compression part 32 by the connecting silicone 33. The connecting silicone 33 is used to form an isolation layer after connecting the wiring part 6, so as to ensure that the wiring part 6 can play a sealing and waterproof role while moving up and down in the through hole.

[0048] The locking foot portion 34 includes a rigid portion 341 located on the outer side of segment B. The rigid portion 341 ensures that the retractable foot portion 34 always conforms to the shape of the sealing groove 23, making insertion into the sealing groove 23 easier and preventing insertion difficulties due to deformation. The rigid portion 341 is fixedly connected to the bottom of the sealing sleeve 31 via a soft pleated portion 342. The bottom end of the rigid portion 341 is fixedly connected to the bottom of the sealing sleeve 31 via a flexible connecting layer 343. The flexible connecting layer 343 and the soft pleated portion 342 fix the rigid portion 341 to the locking foot portion 34, allowing the rigid portion 341 to make room during insertion. After insertion into the sealing groove 23, the first locking mechanism 27 and the second locking mechanism 25 compress the flexible compression layer 344, causing it to indent inward, creating a compressed inner cavity. This allows the flexible silicone layer 28 to contact the concave inner arc surface, thereby forming... To achieve a tight and waterproof state, a flexible compression layer 344 is provided on the inner side of section B. The inner side of the flexible compression layer 344 is fixedly connected to the inner wall of the rigid part 341 through multiple compression columns 3412. After the flexible compression layer 344 is compressed, the compression columns 3412 on the flexible compression layer 344 can be moved outward, and the rigid part 341 will be in the sealing groove 23, forming a state of tight contact with the inner wall of the outer side of the sealing groove 23. Of course, in the specific implementation of this scheme, the inner wall of the outer side of the sealing groove 23 is optimally designed to be inclined from top to bottom, so that the rigid part 341 after being compressed fits against the inner wall, improving the firmness after sealing, forming a wedge shape, and thus playing a role in preventing detachment. It can improve the firmness between the female end sleeve 3 and the fixed wiring part 2. During vehicle operation, the vibration generated will not affect the sealing performance and the fixed state. The cross-section of the flexible connecting layer 343 and the soft pleated part 342 are both wavy, with edges formed on the outside, and the edges contact the inner wall of the sealing groove 23.

[0049] The locking foot part 34 also includes four recessed openings 345, and guide rods 346 are elastically provided in the recessed openings 345. The bottom ends of the four guide rods 346 abut against the guide groove 272 and the guide notch 253 respectively.

[0050] This embodiment also includes an isolation protrusion 347, located on the outer side of section A. The outer end of the isolation protrusion 347 is rolled upward to form a drainage channel, which can block the water formed on the surface of the sealing sleeve 31. When the water hanging on the sealing sleeve 31 falls due to gravity, it is dispersed into the drainage channel formed by the upward rolling of the outer ends of the multiple isolation protrusions 347. Furthermore, when the isolation protrusions 347 and the soft pleated portion 342 are in communication, they can form a water-receiving portion around the periphery of the sealing sleeve 31, so that the water in the gap of the soft pleated portion 342 is contained within the water. Water can flow into the drainage channel, and a reinforcing portion 348 is formed on the outside of the isolation protrusion 347. The reinforcing portion 348 can form an isolation layer. During vibration, the reinforcing portion 348 can prevent water from splashing. An external seepage hole 26 is provided near the strip groove 24. A funnel-shaped bladder 3410 is provided in the middle of the reinforcing portion 348 near the external seepage hole 26. The top of the funnel-shaped bladder 3410 is open to the outside, with the top opening 349 located below the reinforcing portion 348. There is a gap between the funnel-shaped bladder 3410 and the locking foot portion 34 for drainage. 4. The inner cavity is connected to introduce air pressure. After the first locking mechanism 27 and the second locking mechanism 25 compress the flexible compression layer 344, the internal air pressure flows into the funnel bladder 3410, causing the funnel bladder 3410 to bulge, thereby increasing the water-receiving range and widening the gap. The reason for the increased gap is that the bulging funnel bladder 3410 is further away from the locking foot part 34, thus increasing the gap between them. Water flows out from the external seepage hole 26, which reduces the water retention rate on the female end sleeve 3. When an air pressure column 3411 is set on the outer side of section A near the strip groove 24, The air column 3411 is connected to the inner cavity of the locking foot part 34. After the air column 3411 is inflated, it is embedded into the strip groove 24. In addition, the inner wall of the sealing sleeve 31 is attached to the top of the fixed wiring part 2, which can achieve a completely closed state. Moreover, through the setting of internal air pressure, it can ensure that the fixed wiring part 2 and the female end sleeve 3 are firmly locked together. When vibration occurs, it can buffer the fixed wiring part 2 and the female end sleeve 3, improve stability, and prevent gaps from appearing in the case of thermal expansion and contraction or excessive vibration frequency, which would allow water vapor to enter the interior.

[0051] In practical use, the first locking mechanism 27 and the second locking mechanism 25 come into contact with the flexible compression layer 344. Through softness The compression layer 344 compresses the internal air pressure, creating a compressed internal cavity space. In this way, the flexible silicone layer 28 can form a contact state with the concave inner arc surface, thereby forming a tight waterproof state. Furthermore, it can push the rigid part 341 outwards to form a tight contact state with the inner wall of the sealing groove 23, reducing gaps and preventing water from accumulating in the gaps, thus improving the waterproof effect. Additionally, when the internal air pressure is compressed... The air pressure shifts from segment B to segment A, causing the air pressure to be diverted into the funnel bladder. Within 3410 and the air pressure column 3411, it expands. It can effectively drain water from the surface and improve the locking effect, preventing water from lingering in the gaps for a long time and reducing the water retention rate. The surface of the female end sleeve 3 is provided with a hydrophobic layer, making it easier for water to be drained.

[0052] Example 3

[0053] Reference Figure 2 and Figure 13 This embodiment includes all the features of Embodiment 1, with the distinguishing feature being that a one-way valve 11 is disposed within the connector sleeve 10, and a support member 291 is disposed within the external exhaust cavity 29. The support member 291 is used to restrict the first locking mechanism 27 and the second locking mechanism 25, and to support the inner wall of the external exhaust cavity 29. The one-way valve 11 includes a connecting pipe 111, which is used to connect the connector sleeve 10 and the external exhaust cavity 29. An external exhaust groove 112 is disposed on the connecting pipe 111, and a threaded block 1 is fixedly connected inside the connecting pipe 111. 15. The adjustable distance of the threaded block 115 allows the compression spring 114 to adjust its compression state, thereby ensuring the sensitivity of the movement of the round plug 113. The top of the threaded block 115 is fixedly connected to the round plug 113 via the compression spring 114. The round plug 113 is located above the outer discharge groove 112. After the sliding plug part 7 is inserted into the connector sleeve 10, the sliding plug part 7 separates the internal space from the external space. As a result, the internal air is compressed during the sliding of the sliding plug part 7, and the air pressure enters the connecting pipe 111, so that the air pressure in the connecting pipe 111 is relative to the round plug 113. Pressure is applied to the plug 113, causing it to move below the outer exhaust groove 112. This connects the connector sleeve 10 with the outer exhaust cavity 29, allowing internal air pressure to enter the outer exhaust cavity 29. This causes the flexible silicone layer 28 to expand and form a flexible compression layer 344, creating an inner seal. When the sliding plug 7 is fully inserted into the bottom of the inner wall of the connector sleeve 10, the internal air is completely emptied. Since the interior is completely emptied, the plug 113 remains in a downward position. Alternatively, when the power terminal 5 and the two signal terminals 4 on the right are pulled externally, the sliding plug 7 will create a suction effect during the reset process of the connector sleeve 10. At this time, the round plug 113 can completely block the outer drain groove 112, thus creating a negative pressure state inside the connector sleeve 10. When the wiring part 6 receives the pulling force, the negative pressure state creates an adsorption force on the sliding plug 7, which can ensure that the sliding plug 7 is always located inside the connector sleeve 10, thereby ensuring the stability of the connection and preventing the occurrence of a loose connection.

[0054] Example 4

[0055] Reference Figure 8 and Figure 12This embodiment includes all the features of embodiment 1, and its distinguishing features are: three connector sleeves 10 disposed on the fixed wiring part 2, power wiring terminal 5 disposed in the left connector sleeve 10 and two signal wiring terminals 4 disposed on the right side, wiring part 6 disposed on the power wiring terminal 5 and the signal wiring terminal 4, compression slide 9 elastically disposed at the bottom of the power wiring terminal 5 and the signal wiring terminal 4, and sliding plug part 7 disposed at the bottom of the compression slide 9.

[0056] The sliding plug part 7 includes a plug body 71, a wire foot opening 72 is provided on the plug body 71, and a movable guide seat 73 is provided on the plug body 71 and the extrusion slide 9.

[0057] The wiring section 6 includes a metal electrode 61, which is embedded in the power terminal 5 or the signal terminal 4. The bottom end of the metal electrode 61 is fixedly connected to a branched conductor 63 via an elastic electrode 62. The elastic electrode 62 ensures stable contact when the branched conductor 63 holds the connector pin 22 in place, mitigating the backward pulling force generated by connector vibration. The bottom end of the branched conductor 63 has a guide slope 64. The signal terminal 4 includes a rubber... The body 41 has a slide groove 410 on which the compression slide 9 is mounted. A movable opening 42 is opened on one side of the inner wall of the slide groove 410. A locking groove 43 is provided in the inner cavity of the movable opening 42. The bifurcated conductor 63 is exposed in the locking groove 43. A rocker arm 45 is hinged in the movable opening 42. One end of the rocker arm 45 is hinged to a locking ball 44 through a movable joint 47. The locking ball 44 is covered with insulating rubber 46. A guide bead 48 is provided at one end of the rocker arm 45. A wiring hole 49 is provided at the bottom of the rubber body 41.

[0058] In use, when the connecting pin 22 is inserted, it first passes through the lead hole 72 on the plug body 71. As it passes through the lead hole 72, it pushes the guide seat 73 to one side. After the guide seat 73 is displaced, one end of the guide seat 73 disengages from the bottom of the rubber body 41. Then, the pressing slide 9 on the rubber body 41 moves into the slide groove 410. When the connecting pin 22 is fully inserted into the wiring hole 49, it contacts the guide inclined surface 64, which separates the two branch conductors 63 and allows it to be clamped by the branch conductors 63. When the terminal 22 is clamped, when it moves to the guide bead 48 in the slide groove 410, the guide bead 48 can drive the rocker arm 45 to move upward at one end of the slide groove 410, and then the other end of the rocker arm 45 moves downward. In this way, the other end of the rocker arm 45 drives the locking ball 44 to move to the bottom of the inner cavity of the locking groove 43, which is a combination of trapezoidal and rectangular shapes. In this way, the locking ball 44 can move to one side of the bifurcated conductor 63 under the action of the inclined plane, and thus form a locked state to prevent vibration from causing poor contact.

[0059] When this connector is used in a specific application;

[0060] First, stretch the compression part 32 to the extended state. At this time, the locking foot part 34 at the bottom of the sealing sleeve 31 extends out. After the locking foot part 34 is inserted into the sealing groove 23, the installation is achieved. At this time, the sliding plug part 7 is inserted into the connector sleeve 10.

[0061] Then, the compression part 32 is pressed down. At this time, the signal terminal 4 and power terminal 5 on the compression part 32 move into the connector sleeve 10. In this way, the sliding plug part 7 on the signal terminal 4 and power terminal 5 gradually compresses the gas in the connector sleeve 10 into the one-way valve 11 and opens the one-way valve 11, so that the gas enters the external exhaust flow chamber 29.

[0062] During the above process, the sealing sleeve 31 is simultaneously subjected to pressure, and the guide rod 346 is simultaneously squeezed with the guide notch 253 and the guide groove 272 on the lever 271. At this time, the insertion end 2710 on the lever 271 moves into the outer extrusion groove 279, and when the inner wall of the outer extrusion groove 279 is squeezed, the U-shaped part 273 can move towards section b. The ball 278 and the insertion end 2710 form a squeezing state. At the same time as the U-shaped part 273 moves towards section b, the side of the U-shaped part 273 located at the insertion end 2710 expands outward, so that the outer side of the U-shaped part 273 can completely fit against the inner wall of the female end sleeve 3 and form a squeezing state. The first locking mechanism 27 and the second locking mechanism 25 can lock the inner side of the female end sleeve 3.

[0063] In addition, the first locking mechanism 27 and the second locking mechanism 25 are in contact with the flexible compression layer 344. The flexible compression layer 344 compresses the internal air pressure to form a compressed internal cavity space. In this way, the flexible silicone layer 28 can form a contact state with the concave inner arc surface. Moreover, after the air pressure column 3411 is filled with air, it forms a state of being embedded into the strip groove 24.

[0064] During the insertion of the plug part 7 into the bottom of the inner wall of the connector sleeve 10, when the connecting foot 22 is inserted, it first passes through the wire hole 72 on the plug body 71. When it passes through the wire hole 72, it will push the guide seat 73 to one side. After the guide seat 73 is displaced, one end of the guide seat 73 will disengage from the bottom of the rubber body 41. Then, the extrusion slide 9 on the rubber body 41 will move into the slide groove 410. When the connecting foot 22 is fully inserted into the wiring hole 49, it will contact the guide inclined surface 64. This will allow the bifurcated conductors 63 on both sides to be... The terminals are separated and can be clamped by the forked conductor 63. When the terminal 22 is clamped, when it moves to the guide bead 48 in the slide groove 410, the guide bead 48 can drive the rocker arm 45 to move upward at one end of the slide groove 410, and then the other end of the rocker arm 45 moves downward. In this way, the other end of the rocker arm 45 drives the locking ball 44 to move to the bottom of the inner cavity of the locking groove 43, which is a combination of trapezoidal and rectangular shapes. In this way, the locking ball 44 can move to one side of the forked conductor 63 under the action of the inclined plane, and thus form a locked state.
