Description

Technical Field

[0001] This application relates to the technical field of wireless transmission devices, and in particular to an integrated wireless transmission connector. Background Technology

[0002] Based on the current automotive development trend of "the four new trends"—electrification, intelligentization, connectivity, and lightweighting—vehicles are facing increasingly higher requirements in terms of integration and lightweighting. Wireless communication offers several advantages: 1. Good mobility: RF modules can be installed anywhere within communication range to meet communication requirements. 2. Quicker and more flexible installation: Avoids environmental interference and complex work such as trenching and wiring. 3. Lower investment: Avoids wiring and subsequent maintenance costs. 4. Meets the current trend of lightweighting. Wireless communication has already achieved mature applications in Wi-Fi, IoT, smart homes, and drones. Applying wireless technology to automotive signal communication is also attracting significant attention as a new development trend.

[0003] Related technologies disclose several automotive built-in integrated antenna technologies, which mainly include a housing and a wireless transmission module housed inside the housing. For example, patent document CN209981460U discloses an automotive built-in integrated antenna that includes a housing and electrical modules such as a printed antenna and a receiving module installed inside the housing. The housing has a mounting bracket with mounting holes. Screws are passed through the mounting holes and then threaded onto the vehicle body to install the integrated antenna. The housing has signal lines that connect to the internal electrical modules, and the signal lines have interfaces for connecting to a power source or other devices.

[0004] In related technologies, automotive built-in integrated antennas are equipped with signal lines that connect to electrical modules. The presence of these signal lines undoubtedly increases the production cost and complexity of the built-in integrated antennas, thus affecting their production efficiency. Summary of the Invention

[0005] To improve the production efficiency of automotive built-in wireless modules, this application provides an integrated wireless transmission connector.

[0006] The integrated wireless transmission connector provided in this application adopts the following technical solution:

[0007] An integrated wireless transmission connector includes a wireless radio frequency chip and a connector body. The wireless radio frequency chip is embedded inside the connector body through an integral injection molding process. The wireless radio frequency chip is provided with metal pins. The connector body has slots at the positions corresponding to the metal pins. The slots are used for inserting a plug of a signal line.

[0008] By adopting the above technical solution, the connector body encapsulates the wireless RF chip internally through an integral injection molding process, thus protecting the chip. Slots are formed at the locations of the metal pins for the insertion of signal line plugs. In this application, the connector body serves as both a plug and a housing, enabling it to perform multiple functions and resulting in a smaller overall size and higher integration of the wireless transmission connector. Furthermore, compared to integrated antennas in related technologies, it eliminates the need for setting signal lines on the connector body, improving the overall production efficiency of the wireless transmission connector.

[0009] Optionally, the plug of the signal line is in the form of a block structure, and a connection slot is provided on the plug. The data line is inserted into the connection slot, the plug is inserted into the slot, and the metal pins are inserted into the connection slot.

[0010] By adopting the above technical solution, the plug is inserted into the slot to connect the plug and the connector body, and the metal pins are inserted into the connection groove to connect with the data cable. Here, the plug and slot are mainly used to improve the stability of the connection between the metal pins and the data cable.

[0011] Optionally, a buckle is provided on the side wall of the plug, the buckle includes a limiting member movably connected to the plug, and a limiting groove is provided on the side wall of the slot, one side of the limiting member is inserted into the limiting groove, and the limiting member can move closer to or further away from the limiting groove.

[0012] By adopting the above technical solution, one side of the limiting block is inserted into the limiting groove to limit the plug, improve the stability of the connection between the plug and the connector body, and thus achieve the effect of stable signal transmission.

[0013] Optionally, the connector body is provided with a locking structure, which is used to prevent the connector body from detaching from the vehicle body sheet metal.

[0014] By adopting the above technical solution, the connector body is fixed by a clip structure to achieve the connection between the connector body and the vehicle body sheet metal.

[0015] Optionally, the snap-fit ​​structure includes a mounting element and a barb. One end of the mounting element is vertically connected to the connector body, and one side of the barb is connected to the side wall of the connector element, while the other side is inclined towards the connector body.

[0016] By adopting the above technical solution, process holes are opened on the vehicle body sheet metal. When installing the connector body, the mounting part is aligned with the process hole and inserted into it. As the mounting part is inserted, the barbs abut against the edge of the process hole and deform, allowing the mounting part to be smoothly inserted into the process hole. When the barbs move to the side of the vehicle body sheet metal away from the connector body, the barbs spring back, thereby preventing the mounting part from detaching from the process hole, achieving rapid installation of the connector body.

[0017] Optionally, the connector body is provided with a clamping member, one side of which is connected to the connector body and the other end extends toward the mounting member, and the clamping member is made of an elastic material.

[0018] By adopting the above technical solution, the elastically set clamping member allows for a certain amount of movement. After the barb moves to the side of the vehicle body sheet metal away from the connector body, the barb and the clamping member use their own elasticity to clamp onto the vehicle body sheet metal, thereby improving the stability of the connector body after it is fixed.

[0019] Optionally, the pin structure includes a pin and a movable stop. One end of the pin is vertically connected to the connector body. The shape of the pin corresponds to the process hole opened on the vehicle body sheet metal. The pin can be inserted into the process hole. An installation groove is opened on the side wall of the pin. The movable stop is rotatably connected in the installation groove. Rotating the movable stop can move one side of the movable stop to the outside of the installation groove and closer to the connector body.

[0020] By adopting the above technical solution, the movable stop is rotatably connected to the pin. Before the connector body is installed, the movable stop is entirely located inside the mounting groove. After the pin is inserted into the process hole, the movable stop is rotated to move it outside the mounting groove, and the end of the stop presses against the vehicle body sheet metal to fix the connector body. The shape of the pin corresponds to the process hole, and the fit clearance between them can be set to be smaller, which can reduce the displacement of the connector body in the direction parallel to the vehicle body sheet metal after installation, further improving the stability of the connector body after installation.

[0021] Optionally, the pin is provided with a drive component slidably connected to the pin for driving the movable stop block to rotate. The movable stop block has multiple teeth around its own rotation axis on the side near the drive component. The drive component has corresponding tooth grooves. The pin is provided with an elastic component for driving the drive component to slide. The sliding of the drive component can drive the movable stop block to rotate. The connector body is provided with an adjustable clamping component. The adjustable clamping component can limit the sliding of the drive component and can release the limit on the drive component after the connector body abuts against the vehicle body sheet metal.

[0022] By adopting the above technical solution, before the connector body is installed, the adjustable clamping component limits the drive component, thereby enabling the movable stop block to be stably placed in the mounting slot. When the connector body abuts against the vehicle body sheet metal, the adjustable clamping component is triggered, and the limitation on the drive component is canceled. At this time, under the action of the elastic component, the drive component moves automatically to drive the movable stop block to press against the vehicle body sheet metal, realizing the rapid installation of the connector body.

[0023] Optionally, the adjustable clamping assembly includes an elastic clip and a linkage ring. The elastic clip is mounted on the connector body, with one end of the elastic clip abutting against the drive component. The linkage ring can move in a direction parallel to the pin, with one end of the linkage ring abutting against the elastic clip. The movement of the linkage ring can deform the elastic clip, and the deformation of the elastic clip can disengage it from the drive component. During the insertion of the pin into the process hole, the linkage ring can abut against the vehicle body sheet metal.

[0024] By adopting the above technical solution, the connector body mounting component and the elastic card use their own elasticity to press against the driving component, thereby limiting the movement of the driving component. After the pin is installed, the linkage ring abuts against the vehicle body sheet metal. As the connector moves, the linkage ring moves relative to it, causing the elastic card to deform and cancel the limiting effect on the driving component, thus automatically releasing the limiting effect on the driving component.

[0025] Optionally, the connector body is provided with a driving assembly, the driving assembly including a fixed block fixedly connected to the driving component and a rotating block rotatably connected to the connector body. The fixed block is provided with a spiral rising surface extending along a spiral line, and the rotating block is provided with a mating surface corresponding to the spiral rising surface. Rotating the rotating block allows the mating surface to abut against the spiral rising surface.

[0026] By adopting the above technical solution, rotating the rotating block allows the connector to abut against the fixed block. Applying force to the rotating block adjusts the force of the movable abutment against the vehicle body sheet metal, improving the flexibility of connector body installation. Simultaneously, the friction between the spiral rising surface and the mating surface limits the sliding of the drive block, improving the stability of the connector body after installation.

[0038] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0039] This application discloses an integrated wireless transmission connector.

[0040] Reference Figure 1 and Figure 2 An integrated wireless transmission connector includes a wireless radio frequency chip 1 and a connector body 2, wherein the wireless radio frequency chip 1 is embedded inside the connector body 2. In this embodiment, the connector body 2 is manufactured by injection molding, and the wireless radio frequency chip 1 is integrally injection molded inside the connector body 2 during the injection molding process, thereby realizing the connection between the connector body 2 and the wireless radio frequency chip 1.

[0041] Reference Figure 1 and Figure 3The wireless RF chip 1 has metal pins 11, which in this embodiment are 4-pin pins (specifically, ground GND, data positive D+, data negative D-, and power supply VCC). A slot 21 is provided on the connector body 2 corresponding to the 4-pin pin position, and the 4-pin pin extends into the slot 21. A plug 22 is provided on the data cable in the vehicle corresponding to the slot 21. The plug 22 can be inserted into the slot 21, connecting the data cable to the 4-pin pin, thus enabling power supply and data transmission for the wireless RF chip 1.

[0042] Reference Figure 1 and Figure 2 The plug 22 has a block-like structure, and the data cable is fixedly connected to the plug 22. A connection slot (not shown in the figure) is provided on the plug 22, and the end of the data cable is inserted into the connection slot. After the plug 22 is inserted into the slot 21, the 4-pin connector is inserted into the connection slot and connected to the data cable. A latch 221 is provided on the side wall of the plug 22. The latch 221 includes a limiting member 2212 and a movable member 2211. The movable member 2211 has a rectangular block-like structure and is arranged parallel to the opening direction of the slot 21. One end is fixed to the plug 22, and the other end extends to the outside of the slot 21. The limiting member 2212 is fixed to the side of the movable member 2211 away from the plug 22. A limiting groove is provided on the side wall of the slot 21 corresponding to the limiting member 2212, and the side of the limiting member 2212 away from the limiting member 2212 is inserted into the limiting groove. This prevents the plug 22 from detaching from the slot 21, improving the stability during data transmission. The movable part 2211 is made of an elastic material; in this embodiment, the movable part 2211 is made of plastic. The movable part 2211 can be bent toward the plug 22, thereby driving the limiting part 2212 toward the plug 22, and then causing the limiting part 2212 to disengage from the limiting groove, thus realizing a detachable connection between the plug 22 and the connector body 2.

[0043] Reference Figure 1 and Figure 2 A slider 222 is integrally formed on the side wall of the plug 22, and a sliding groove is provided on the side wall of the slot 21. During the process of inserting the plug 22 into the slot 21, the slider 222 enters the sliding groove and slides with the sliding groove to guide the sliding of the plug 22 and improve the stability of the plug 22 during the insertion process into the slot 21.

[0044] Reference Figure 1 and Figure 2The connector body 2 is also provided with a locking structure 3, which includes a mounting member 31 and a barb 32. One end of the mounting member 31 is vertically connected to the side wall of the connector body 2. One side of the barb 32 is fixed to the mounting member 31, and the other side is inclined along the length of the mounting member 31 from the side away from the connector body 2 to the side closer to the connector body 2, and then towards the side away from the mounting member 31. The barb 32 is made of elastic material, and the side of the barb 32 away from the mounting member 31 can be bent towards the side closer to the mounting member 31. The vehicle body is generally a sheet metal structure, and process holes are opened on the sheet metal of the vehicle body, which penetrate the sheet metal. When installing the connector body 2, the mounting member 31 is inserted into the process hole. During the insertion of the mounting member 31, the barb 32 abuts against the side wall of the process hole, and the barb 32 deforms, allowing the mounting member 31 to be smoothly inserted into the process hole. When the barb 32 moves to the side of the vehicle body sheet metal away from the connector body 2, the barb 32 springs back and abuts against the side of the sheet metal away from the connector body 2 to achieve a quick connection between the connector body 2 and the vehicle body sheet metal.

[0045] Reference Figure 1 and Figure 2 Multiple barbs 32 are arranged parallel to each other along the length of the mounting member 31 to facilitate the connection of the connector body 2 with sheet metal of different thicknesses, thereby improving the applicability of the integrated wireless transmission connector. To improve the stability of the connector body 2 after installation, two locking structures 3 are provided, spaced apart, with the barbs 32 located on the opposite sides of the two mounting members 31. A block-shaped reinforcing member 33 is provided between the two mounting members 31, and the reinforcing member 33 is also provided with barbs 32 to further improve the stability of the connector body 2 after installation.

[0046] Reference Figure 1 and Figure 2 The connector body 2 is also provided with a clamping member 34, which has an overall annular structure. One end of the clamping member 34 is fixedly connected to the connector body 2. The mounting member 31 and the reinforcing member 33 are both disposed inside the clamping member 34. The cross-section of the end of the clamping member 34 away from the connector is larger than the cross-section of the end closer to the connector body 2. The clamping member 34 is made of elastic material, so that after the mounting member 31 is inserted into the process hole on the vehicle body sheet metal, the clamping member 34 can clamp against the vehicle body sheet metal from the side away from the barb 32. Under the action of the barb 32 and the clamping member 34, the displacement of the multiple mounting members 31 in multiple directions is limited, further improving the stability of the connector body 2 after installation.

[0047] The implementation principle of an integrated wireless transmission connector in this application embodiment is as follows: During the installation of the connector body 2, the barb 32 abuts against the edge of the process hole on the vehicle body sheet metal and deforms under the action of force, so that the mounting part 31 can be smoothly inserted into the process hole. After the barb 32 moves to the other side of the vehicle body sheet metal, it presses against the vehicle body sheet metal, realizing a quick connection between the connector body 2 and the vehicle body, and improving the overall efficiency of the automobile assembly process. Example

[0048] Reference Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 lies in the structure of the latch structure 3. In this embodiment, the latch structure 3 includes a mounting base 35 and a movable stop block 36. The mounting base 35 includes a base 351 and a pin 352. The base 351 is a plate-like structure, which is parallel to the side wall of the connector body 2 and fixedly connected to the connector body 2. The pin 352 is generally a rectangular block structure, with one end vertically fixedly connected to the base 351. A mounting groove is provided on the side wall of the pin 352, and the movable stop block 36 is rotatably connected in the mounting groove. The rotation axis of the movable stop block 36 is perpendicular to the length direction of the pin 352. Rotating the movable stop block 36 allows one side of the movable stop block 36 to move outside the mounting groove. The shape of the pin 352 corresponds to the process hole on the vehicle body sheet metal, so that the pin 352 can be inserted into the process hole.

[0049] Reference Figure 4 and Figure 5 In this embodiment, the movable stop block 36 is made of a rigid material. After the pin 352 is inserted into the process hole, rotating the movable stop block 36 allows one side of the movable stop block 36 to move outside the mounting slot, thereby preventing the pin 352 from detaching from the vehicle body sheet metal and realizing the installation of the connector body 2. Simultaneously, as the movable stop block 36 rotates, its end gradually approaches the connector body 2, thereby pressing against the vehicle body sheet metal and further securing the connector body 2. The rotational design of the movable stop block 36 allows it to be made of a rigid material, and the force exerted by the movable stop block 36 against the vehicle body sheet metal can be controlled and adjusted according to the degree of rotation, making the connector body 2 more stable after installation and reducing the possibility of the connector body 2 vibrating and falling off during vehicle operation.

[0050] Reference Figure 4 and Figure 5 Multiple movable blocks 36 are provided along the circumference of the pin 352 corresponding to the side wall of the pin 352, and multiple sets are provided at intervals along the length of the pin 352. This improves the stability of the connector body 2 after installation, so that the connector body 2 can be installed on the vehicle body sheet metal with large differences in thickness.

[0051] Reference Figure 4 and Figure 5 The pin 352 is hollow inside, and a drive member 37 is slidably arranged along the length of the pin 352. The movable stop 36 has an arc-shaped surface coaxial with its own rotation axis on the side near the drive member 37. Multiple teeth are evenly spaced along its circumference on the arc-shaped surface. Multiple tooth grooves that mesh with the teeth are slidably opened on the side wall of the drive member 37 along the length of the pin 352. The sliding drive member 37 can drive multiple movable stops 36 to rotate, so that the connector body 2 can be quickly locked and fixed regardless of the thickness of the vehicle body sheet metal it is installed on.

[0052] Reference Figure 5 and Figure 6 The pin 352 is also provided with a pre-fixing component 4, which includes an elastic element 41 and an adjustable clamping component 42. The elastic element 41 is installed inside the pin 352 and is located on the side of the drive member 37 away from the connector body 2. The elastic element 41 is used to apply a force to the drive member 37 to move the drive member 37 away from the base 351. The end of the movable abutment 36 away from its own axis of rotation is defined as the abutment end, which can abut against the vehicle body sheet metal. The movement of the drive member 37 away from the base 351 can move the abutment end to the outside of the mounting groove. The adjustable clamping component 42 is used to limit the position of the drive member 37. Before the pin 352 is inserted into the process hole, the abutment end is located in the mounting groove and is located on the side of its own axis of rotation away from the base 351. In this state, the elastic element 41 applies a force to the driving element 37, causing it to move away from the base 351. At the same time, the adjustable clamping assembly 42 limits the driving element 37, preventing its movement, thus keeping the overall pin structure 3 in a stable state. When the pin 352 is inserted into the process hole, the adjustable clamping assembly 42 releases the limit on the driving element 37, causing the driving element 37 to drive the movable stop block 36 to rotate automatically, thereby automatically fixing the connector body 2.

[0053] Reference Figure 6 and Figure 7 The adjustable clamping assembly 42 includes a moving component 43 and an elastic clip 44. The moving component 43 includes a connecting rod and a fixed ball. One end of the connecting rod is fixedly connected to the side wall of the driving component 37 near the base 351. The fixed ball is fixed to the end of the connecting rod away from the driving component 37. A receiving groove 45 is provided on the base 351 corresponding to the fixed ball, and the fixed ball is located in the receiving groove 45. One end of the elastic clip 44 is fixed to the side wall of the receiving groove 45, and the other end abuts against the fixed ball and is located on the side of the fixed ball's center near the driving component 37, thereby preventing the fixed ball from detaching from the receiving groove 45. The elastic clip 44 is made of elastic material, and the end of the elastic clip 44 near the fixed ball can be bent away from the driving component 37. Bending the elastic clip 44 can cause it to detach from the fixed ball, thereby removing the restriction on the driving component 37.

[0054] Reference Figure 6 and Figure 7 The adjustable clamping assembly 42 also includes a limiting ring 46. The receiving groove 45 is a circular groove, and the limiting ring 46 is correspondingly set as a circular ring, coaxially disposed inside the receiving groove 45, and located on the side of the elastic card 44 near the driving member 37. The outer wall of the limiting ring 46 is attached to and fixedly connected to the side wall of the receiving groove 45. The limiting ring 46 can prevent the elastic card 44 from bending towards the driving member 37, thereby improving the stability of the elastic card 44 in limiting the fixed ball.

[0055] Reference Figure 6 and Figure 7 The adjustable clamping assembly 42 also includes a linkage ring 47, which is a circular ring structure. It is coaxially disposed inside the limiting ring 46 and slides with the limiting ring 46. The linkage ring 47 is located on the side of the elastic card 44 near the driving component 37. A linkage rod 48 is fixedly disposed on the linkage ring 47. One end of the linkage rod 48 is connected to the linkage ring 47, and the other end extends to the outside of the pin 352. During the installation of the connector body 2, the base 351 is close to the vehicle body sheet metal, which can abut against the linkage rod 48. As the base 351 moves, it drives the linkage rod 48 to move, which in turn drives the linkage ring 47 to move. The movement of the linkage ring 47 exerts force on the elastic card 44, causing it to bend and disengage from the fixed ball, automatically releasing the limiting of the fixed ball, thus realizing the rapid installation of the connector body 2.

[0056] Reference Figure 6 and Figure 8 A drive assembly 5 is provided on the side of the drive component 37 near the base 351. The drive assembly 5 includes a fixed block 51 and a rotating block 52, both of which are cylindrical structures. The fixed block 51 is fixedly mounted on the side of the drive component 37 near the base 351. The rotating block 52 is coaxially mounted with the fixed block 51 and is rotatably connected to the base 351 around its own axis. The fixed block 51 is provided with a spiral rising surface 53; the spiral rising surface 53 extends along a spiral line coaxial with the fixed block. The rotating block 52 is provided with a mating surface parallel to the spiral rising surface 53 at a position corresponding to the position of the spiral rising surface 53. Rotating the rotating block 52 utilizes the interaction between the spiral rising surface 53 extending along the spiral line and the mating surface to drive the driving component 37 to move, thereby enabling the driving component 37 to move away from the base 351, which in turn enables the abutting end of the movable abutting block 36 to press against the vehicle body sheet metal. Furthermore, the abutting force between the abutting end and the vehicle body sheet metal can be controlled by the rotation angle of the rotating block 52.

[0057] Reference Figure 6 and Figure 9A driving cavity 54 is formed on the side of the base 351 opposite to the driving member 37, and the end of the rotating block 52 away from the driving member 37 extends into the driving cavity 54. Two dividing plates 55 are provided on the side wall of the driving cavity 54, and the two dividing plates 55 are evenly spaced along the circumference of the driving cavity 54. The dividing plates 55 are arranged radially along the rotating block 52, and the side of the dividing plate 55 closest to the rotating block 52 abuts against the rotating block 52 and is sealed. Two movable plates 56 are provided on the rotating block 52, and the two movable plates 56 are spaced along the circumference of the rotating block 52. The side of the movable plate 56 away from the rotating block 52 abuts against the side wall of the driving cavity 54 and is sealed.

[0058] Reference Figure 6 and Figure 9 When air is introduced between the dividing plate 55 and the movable plate 56, the gas pressure drives the rotating block 52 to rotate. Under the action of the dividing plate 55 and the movable plate 56, the driving cavity 54 is divided into four cavities, which are then divided into two groups. The two groups of cavities are defined as locking cavities 57 and releasing cavities 58. The gap between the two locking cavities 57 corresponds to the gap between the two contact cavities. When high-pressure gas is introduced into the locking cavity 57, it drives the rotating block 52 to rotate in the forward direction (the direction of rotation when the rotating block 52 drives the driving component 37 away from the base 351), thereby allowing the movable abutment 36 to press against the vehicle body sheet metal. This avoids traditional screw or clip 221 connections, thus reducing the likelihood of non-professional personnel disassembling the connector body 2 and reducing the risk of damage to the wireless module due to unprofessional disassembly.

[0059] Reference Figure 6 and Figure 9 The base has two gas channels, one of which connects to the two locking chambers 57, and the other connects to the releasing chamber 58. The gas channels form interfaces 59 on the side walls of the base to allow operators to inject high-pressure gas into either the locking chamber 57 or the releasing chamber 58 using an air gun.

[0060] Reference Figure 9 and Figure 10 The dividing plate 55 is provided with a pressure-adaptive locking assembly 6 for limiting the rotation of the rotating block 52. The pressure-adaptive locking assembly 6 includes a locking plate 61 and a piston block 62. A sliding channel 64 is formed inside the dividing plate 55, and the sliding cavity forms an opening on the side near the rotating block 52. The locking plate 61 is slidably connected to the sliding cavity along the radial direction of the rotating block 52, and one side of the locking plate 61 abuts against the rotating block 52. The friction between the locking plate 61 and the rotating block 52 is used to limit the rotation of the rotating block 52, thereby improving the stability of the connector body 2 after installation.

[0061] Reference Figure 9 and Figure 10The pressure-adaptive locking assembly 6 also includes a force-applying element 63, which is disposed in the sliding cavity and is used to maintain the locking plate 61 in a direction closer to the rotating block 52. In this embodiment, the force-applying element 63 is a spring, with one end welded to the side wall of the sliding cavity and the other end welded to the locking plate 61. Under the action of the force-applying element 63, the locking plate 61 can apply a certain force to the rotating block 52, so that a certain frictional force is maintained between the locking plate 61 and the rotating block 52.

[0062] Reference Figure 9 and Figure 10 The pressure-adaptive locking assembly 6 also includes a piston block 62, which is a rectangular block structure. A sliding channel 64 is provided on the dividing plate 55 along a direction perpendicular to itself, and the piston block 62 slides within the sliding channel 64. A through hole is provided on the locking plate 61 corresponding to the position of the piston block 62, allowing the piston block 62 to pass through the locking plate 61. Two driving inclined surfaces 65 are provided on the piston block 62, respectively positioned on both sides of the locking plate 61 in the thickness direction. The driving inclined surfaces 65 are radially inclined along the rotating block 52 from the side closest to the rotating block 52 to the side furthest from the rotating block 52, moving in a direction away from each other. When the piston block 62 moves, the driving inclined surfaces 65 can drive the locking plate 61 away from the rotating block 52.

[0063] Reference Figure 9 and Figure 10 In actual operation, when high-pressure gas is introduced into the locking chamber 57 or the releasing chamber 58, the pressure inside the locking chamber 57 or the releasing chamber 58 increases, which can drive the piston block 62 to move, thereby driving the locking plate 61 away from the rotating block 52, thus releasing the limitation on the rotating block 52. At this time, with the continuous introduction of high-pressure gas, the rotating block 52 can be driven to rotate. When the introduction of air into the locking chamber 57 or the releasing chamber 58 is stopped, the spring rebounds, causing the locking plate 61 to press against the rotating block 52, automatically limiting the rotation of the rotating block 52.

[0064] The implementation principle of an integrated wireless transmission connector in this application embodiment is as follows: the movable stop 36 of the movable connection limits the pin 352, so that the overall stability of the connector body 2 is better during the large-scale installation process. By adjusting the degree of rotation of the movable stop 36, the stability of multiple connector bodies 2 after installation can be made more consistent, reducing the situation of inconsistent stability of the connector after installation caused by the error of the thickness of the vehicle body sheet metal or the production error of the movable stop 36.

[0065] By using gas pressure to control the drive movement, the situation where the connector body 2 can be disassembled by traditional tools is avoided, thereby reducing the possibility of non-professionals disassembling the wireless transmission connector and causing damage to the wireless transmission connector.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
