Technical Field

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

[0002] Based on the current development trend of automobiles, "New Four Modernizations" - electrification, intelligence, networking, and lightweighting, there are increasingly high requirements for the integration and lightweighting of automobiles. Wireless communication has the following advantages: 1. Good mobility, as long as within the communication range, the RF module can be installed anywhere to meet the communication requirements. 2. Faster and more flexible installation, avoiding complex work such as environmental interference and trenching for wiring. 3. Lower investment, which can avoid the costs of wiring and subsequent maintenance and repair. 4. Meeting the current development trend of lightweighting. Wireless communication has very mature applications in wifi, Internet of Things, smart home, and drones. Moving wireless technology to automotive signal communication has also attracted much attention as a new development trend.

[0003] Some in-vehicle integrated antenna technologies for automobiles are disclosed in the related art, which mainly include a housing and a wireless transmission module disposed inside the housing. For example, the in-vehicle integrated antenna disclosed in the patent document with the publication number CN209981460U includes a housing and electrical modules such as a printed antenna and a receiving module installed inside the housing. An installation bracket is provided on the housing, and an installation hole is opened on the installation bracket. Screws are used to pass through the installation hole and then threadedly connected to the vehicle body to achieve the installation of the integrated antenna. A signal line connected to the internal electrical module is provided on the housing, and an interface is provided on the signal line for easy connection to a power source or other devices.

[0004] In the related art, a signal line is provided on the in-vehicle integrated antenna, and the signal line is connected to the electrical module. The setting of the signal line undoubtedly increases the production cost and process complexity of the in-vehicle integrated antenna, affecting the production efficiency of the in-vehicle integrated antenna. Summary of the Invention

[0005] In order to improve the production efficiency of in-vehicle wireless modules, this application provides an integrated wireless transmission connector.

[0006] The integrated wireless transmission connector provided by this application adopts the following technical solutions: An integrated wireless transmission connector includes a wireless radio frequency chip and also includes a connector body. The wireless radio frequency chip is built into the connector body through an integral injection molding process. Metal pins are provided on the wireless radio frequency chip, and slots corresponding to the metal pins are opened on the connector body. The slots are used for inserting the plugs of signal lines.

[0007] By adopting the above technical solution, the connector body wraps the radio frequency chip inside itself through an integral injection molding process to protect the radio frequency chip. At the same time, a slot is formed at the position of the metal pin for the plug of the signal line to be inserted. In this application, the connector body is used as a plug and a housing, enabling the connector body to have multiple functions, thereby making the overall volume of the wireless transmission connector smaller and the integration degree higher. Moreover, compared with the integrated antenna in the related art, the process of setting the signal line on the connector body is omitted, improving the overall production efficiency of the wireless transmission connector.

[0008] Optionally, the plug of the signal line is integrally in a block structure, a connection groove is provided on the plug, the data line is inserted into the connection groove, the plug is inserted into the slot, and the metal pin is inserted into the connection groove.

[0009] By adopting the above technical solution, the plug is inserted into the slot to realize the connection between the plug and the connector body, and the metal pin is inserted into the connection groove to connect with the data line. Here, the plug and the slot are mainly used to improve the connection stability between the metal pin and the data line.

[0010] Optionally, a buckle is provided on the side wall of the plug. The buckle includes a limiting member movably connected to the plug. 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 approach or move away from the limiting groove.

[0011] By adopting the above technical solution, one side of the limiting block is inserted into the limiting groove to realize the limitation of the plug, improve the connection stability between the plug and the connector body, and further achieve the effect of stable signal transmission.

[0012] Optionally, a stud structure is provided on the connector body, and the stud structure is used to prevent the connector body from detaching from the vehicle body sheet metal.

[0013] By adopting the above technical solution, the connector body is fixed through the stud structure to realize the connection between the connection body and the vehicle body sheet metal.

[0014] Optionally, the stud structure includes a mounting member and barbs. One end of the mounting member is vertically connected to the connector body. One side of the barb is connected to the side wall of the connecting member, and the other side inclines towards the direction close to the connector body.

[0015] By adopting the above technical solution, a process hole is provided on the vehicle body sheet metal. When installing the connector body, the mounting member is aligned with the process hole and inserted into the process hole. As the mounting member is inserted, the barb abuts against the edge of the process hole and deforms, enabling the mounting member to be smoothly inserted into the process hole. When the barb moves to the side of the vehicle body sheet metal away from the connector body, the barb rebounds, thereby being able to prevent the mounting member from detaching from the process hole and realizing the rapid installation of the connector body.

[0016] Optionally, a pressing member is provided on the connector body. One side of the pressing member is connected to the connector body, and the other end extends towards the mounting member. The pressing member is made of an elastic material.

[0017] By adopting the above technical solution, the elastically arranged pressing member enables the pressing member to have a certain movement space. After the barb moves to the side of the vehicle body sheet metal away from the connector body, the barb and the pressing member are elastically pressed against the vehicle body sheet metal by their own elasticity, improving the stability after the connector body is fixed.

[0018] Optionally, the staple structure includes a plug pin and a movable abutting block. One end of the plug pin is vertically connected to the connector body. The shape of the plug pin corresponds to the process hole opened on the vehicle body sheet metal. The plug pin can be inserted into the process hole. An installation groove is opened on the side wall of the plug pin. The movable abutting block is rotatably connected in the installation groove. Rotating the movable abutting block can make one side of the movable abutting block move outside the installation groove and close to the connector body.

[0019] By adopting the above technical solution, the movable abutting block is rotatably connected to the plug pin. Before the connector body is installed, the whole movable abutting block is located inside the installation groove. After the plug pin is inserted into the process hole, rotate the movable abutting block to make it move outside the installation groove, and make the end part of the plug pin press against the vehicle body sheet metal to fix the connector body. The shape of the plug pin corresponds to the process hole, and the fitting gap between the two can be set smaller, which can reduce the displacement of the connector body in the direction parallel to the vehicle body sheet metal after installation, and further improve the stability after the connector body is installed.

[0020] Optionally, a driving member slidably connected to the plug pin for driving the movable abutting block to rotate is arranged inside the plug pin. A plurality of teeth are arranged on the side surface of the movable abutting block close to the driving member around its rotation axis. A tooth groove is correspondingly arranged on the driving member. An elastic member for driving the driving member to slide is arranged on the plug pin. The sliding of the driving member can drive the movable abutting block to rotate. An adjustable clamping assembly is arranged on the connector body. The adjustable clamping assembly can limit the sliding of the driving member and can release the limit on the driving member after the connector body abuts against the vehicle body sheet metal.

[0021] By adopting the above technical solution, before the connector body is installed, the driving member is limited by the adjustable clamping assembly, so that the movable abutting block can be stably located in the installation groove. When the connector body abuts against the vehicle body sheet metal, the adjustable clamping assembly is triggered to cancel the limit on the driving member. At this time, under the action of the elastic member, the driving member automatically moves to drive the movable abutting block to press against the vehicle body sheet metal, realizing the rapid installation of the connector body.

[0022] Optionally, the adjustable clamping assembly includes an elastic card and a linkage ring. The elastic card is installed on the connector body. One end of the elastic card abuts against the driving member. The linkage ring can move in a direction parallel to the bolt. One end of the linkage ring abuts against the elastic card. The movement of the linkage ring can deform the elastic card. The deformation of the elastic card can disengage from the driving member. During the process of inserting the bolt into the process hole, the linkage ring can abut against the vehicle body sheet metal.

[0023] By adopting the above technical solution, for the connector body installation part, the elastic card uses its own elasticity to tightly press against the driving member, thereby realizing the limit of the driving member. After the bolt is installed, the linkage ring abuts against the vehicle body sheet metal. As the connector moves, the linkage ring moves relatively, causing the elastic card to deform and cancel the limit on the driving member, thereby automatically canceling the limit on the driving member.

[0024] Optionally, a driving assembly is provided on the connector body. The driving assembly includes a fixed block fixedly connected to the driving member 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 for mating with it. Rotating the rotating block, the mating surface can abut against the spiral rising surface.

[0025] By adopting the above technical solution, rotating the rotating block can make it abut against the fixed block. By applying force to the rotating block, the force of the movable abutting block pressing against the vehicle body sheet metal can be adjusted, improving the flexibility of the installation of the connector body. At the same time, the friction between the spiral rising surface and the mating surface is used to limit the sliding of the driving block, improving the stability after the connector body is installed.

Detailed implementation manners

[0037] The following further elaborates on the present application in conjunction with the attached Figures 1 - 10 drawings.

[0038] The embodiment of the present application discloses an integrated wireless transmission connector.

[0039] Referring to Figure 1 and Figure 2 , an integrated wireless transmission connector includes a radio frequency chip 1 and a connector body 2, and the radio frequency chip 1 is embedded inside the connector body 2. In this embodiment, the connector body 2 is completed through an injection molding process, and the radio frequency chip 1 is integrally injection molded inside the connector body 2 during the injection molding process to realize the connection between the connector body 2 and the radio frequency chip 1.

[0040] Referring to Figure 1 and Figure 3, the wireless radio frequency chip 1 is provided with metal pins 11. In this embodiment, the metal pins 11 are 4Pin pins (specifically, ground GND, data positive D+, data negative D-, and power supply VCC). A slot 21 is opened on the connector body 2 at a position corresponding to the 4pin pins, and the 4Pin pins extend into the slot 21. A plug 22 is provided on the vehicle data line corresponding to the slot 21. The plug 22 can be inserted into the slot 21, and the data line is connected to the 4Pin line to achieve the power supply of the wireless radio frequency chip 1 and the transmission of data.

[0041] Refer to Figure 1 and Figure 2 , the plug 22 is integrally in a block structure, and the data line is fixedly connected to the plug 22. A connection groove (not shown in the figure) is provided on the plug 22, and the end of the data line is inserted into the connection groove. After the plug 22 is inserted into the slot 21, the 4Pin pins are inserted into the connection groove to be connected to the data line. A buckle 221 is provided on the side wall of the plug 22. The buckle 221 includes a limiting member 2212 and a movable member 2211. The movable member 2211 is integrally in a rectangular block structure and is arranged parallel to the opening direction of the slot 21. One end of it is fixed on the plug 22, and the other end extends outside the slot 21. The limiting member 2212 is fixed on 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. Thereby, the plug 22 can be blocked from disengaging from the slot 21, improving the stability during the data transmission process. The movable member 2211 is made of an elastic material. In this embodiment, the movable member 2211 is plastic. The movable member 2211 can bend towards the direction close to the plug 22, thereby driving the limiting member 2212 to approach the plug 22, and further enabling the limiting member 2212 to disengage from the limiting groove, realizing the detachable connection between the plug 22 and the connector body 2.

[0042] Refer to Figure 1 and Figure 2 , a slider 222 is integrally formed on the side wall of the plug 22, and a sliding groove is opened on the side wall of the slot 21. During the process of the plug 22 being inserted into the slot 21, the slider 222 enters the sliding groove and slidably cooperates with the sliding groove to guide the sliding of the plug 22, improving the stability during the process of the plug 22 being inserted into the slot 21.

[0043] Refer to Figure 1 and Figure 2, a staple structure 3 is further provided on the connector body 2. The staple structure 3 includes a mounting member 31 and barbs 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 away from the mounting member 31 from the side far from the connector body 2 to the side close to the connector body 2 along the length direction of the mounting member 31. The barb 32 is made of an elastic material, and the side of the barb 32 far from the mounting member 31 can bend towards the side close to the mounting member 31. The vehicle body is generally a sheet metal structure, and a process hole is formed in the vehicle body sheet metal, and the process hole penetrates through the vehicle body sheet metal. When installing the connector body 2, the mounting member 31 is inserted into the process hole. During the insertion process of the mounting member 31, the barb 32 abuts against the side wall of the process hole, and the barb 32 deforms, enabling 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 far from the connector body 2, the barb 32 rebounds and abuts against the side of the sheet metal far from the connector body 2 to achieve rapid connection between the connector body 2 and the vehicle body sheet metal.

[0044] Refer to Figure 1 and Figure 2 , a plurality of barbs 32 are arranged in parallel at intervals along the length direction of the mounting member 31, so as to facilitate the connection between the connector body 2 and vehicle body sheet metals of different thicknesses and improve the universality of the integrated wireless transmission connector. In order to improve the stability of the connector body 2 after installation, two staple structures 3 are provided, and the two staple structures 3 are arranged at intervals. The barbs 32 are arranged on the sides of the two mounting members 31 away from each other. A block-shaped reinforcing member 33 is arranged between the two mounting members 31, and barbs 32 are also arranged on the reinforcing member 33 to further improve the stability of the connector body 2 after installation.

[0045] Refer to Figure 1 and Figure 2 , a tightening member 34 is further provided on the connector body 2. The tightening member 34 is integrally in an annular structure, and one end of it is fixedly connected to the connector body 2. The mounting member 31 and the reinforcing member 33 are both arranged inside the tightening member 34. The cross-section of the end of the tightening member 34 far from the connector is larger than the cross-section of the end close to the connector body 2. The tightening member 34 is made of an elastic material, so that after the mounting member 31 is inserted into the process hole on the vehicle body sheet metal, the tightening member 34 can tighten the vehicle body sheet metal from the side of the vehicle body sheet metal far from the barb 32. Under the action of the barb 32 and the tightening member 34, the displacement of the multi-mounting member 31 in multiple directions is limited, further improving the stability of the connector body 2 after installation.

[0046] The implementation principle of an integrated wireless transmission connector in an embodiment of this application 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, enabling the installation part 31 to be smoothly inserted into the process hole. After the barb 32 moves to the other side of the vehicle body sheet metal, it presses tightly against the vehicle body sheet metal, realizing the rapid connection between the connector body 2 and the vehicle body, and improving the overall efficiency of the automobile assembly process. Embodiment

[0047] Refer to Figure 4 and Figure 5 In this embodiment, the difference from Embodiment 1 lies in the different structure of the staple structure 3. In this embodiment, the staple structure 3 includes a mounting seat 35 and a movable abutting block 36. The mounting seat 35 includes a base 351 and a pin 352. The base 351 is a plate-like structure, which is arranged parallel to the side wall of the connector body 2 and fixedly connected to the connector body 2. The pin 352 is an overall rectangular block structure, and one end of it is vertically and fixedly connected to the base 351. An installation groove is provided on the side wall of the pin 352, and the movable abutting block 36 is rotatably connected in the installation groove. The rotation axis of the movable abutting block 36 is perpendicular to the length direction of the pin 352. By rotating the movable abutting block 36, one side of the movable abutting block 36 can move to the outside of the installation 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.

[0048] Refer to Figure 4 and Figure 5 In this embodiment, the movable abutting block 36 is made of a hard material. After the pin 352 is inserted into the process hole, rotating the movable abutting block 36 can make one side of the movable abutting block 36 move to the outside of the installation groove, thereby preventing the pin 352 from detaching from the vehicle body sheet metal and realizing the installation of the connector body 2. At the same time, as the movable abutting block 36 rotates, the end of the movable abutting block 36 can gradually approach the connector body 2, thereby pressing tightly against the vehicle body sheet metal and further fixing the connector body 2. The rotational setting of the movable abutting block 36 enables the material of the movable abutting block 36 to be selected as a hard material, and the force of the movable abutting block 36 pressing against the vehicle body sheet metal can be controlled and adjusted according to the rotation degree of the movable abutting block 36, making the connector body 2 more stable after installation and reducing the occurrence of the connector body 2 vibrating and falling off during vehicle driving.

[0049] Refer to Figure 4 and Figure 5 A plurality of movable abutting blocks 36 are arranged along the circumferential direction of the pin 352 corresponding to the side wall of the pin 352, and multiple groups are arranged at intervals along the length direction of the pin 352. On the one hand, it improves the stability of the connector body 2 after installation, enabling the connector body 2 to be used on vehicle body sheet metals with a large difference in thickness.

[0050] Refer to Figure 4 andFigure 5 The plug pin 352 is hollow inside, and a driving member 37 is slidably arranged along the length direction of the plug pin 352. On one side of the movable abutting block 36 close to the driving member 37, there is an arc-shaped surface coaxial with its own rotation axis. Along the circumferential direction of the arc-shaped surface, a plurality of teeth are evenly spaced. On the side wall of the driving member 37, a plurality of tooth grooves meshing with the teeth are slidably formed along the length direction of the plug pin 352. Sliding the driving member 37 can drive the plurality of movable abutting blocks 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 on which it is installed.

[0051] Referring to Figure 5 and Figure 6 As shown in FIGS. and, a pre-fixing assembly 4 is further arranged on the plug pin 352. The pre-fixing assembly 4 includes an elastic member 41 and an adjustable clamping assembly 42. The elastic member 41 is installed inside the plug pin 352 and is located on the side of the driving member 37 away from the connector body 2. The elastic member 41 is used to apply a force to the driving member 37 to move the driving member 37 in a direction away from the base 351. Define the end of the movable abutting block 36 away from its own rotation axis as the abutting end, and this end can abut against the vehicle body sheet metal. When the driving member 37 moves in a direction away from the base 351, the abutting end can move to the outside of the installation groove. The adjustable clamping assembly 42 is used to limit the position of the driving member 37. Before the plug pin 352 is inserted into the process hole, the abutting end is located in the installation groove and on the side of its own rotation axis away from the base 351. In this state, the elastic member 41 applies a force to the driving member 37 to move it in a direction away from the base 351, and at the same time, the adjustable clamping assembly 42 limits the driving member 37 to block its movement, so that the whole card structure 3 is in a stable state. After the plug pin 352 is inserted into the process hole, the limit on the driving member 37 is cancelled by the adjustable clamping assembly 42, so that the driving member 37 drives the movable abutting block 36 to rotate automatically, realizing the automatic fixation of the connector body 2.

[0052] Referring to Figure 6 and Figure 7 As shown in FIGS. and, the adjustable clamping assembly 42 includes a moving member 43 and an elastic card 44. The moving member 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 member 37 close to the base 351. The fixed ball is fixed at the end of the connecting rod away from the driving member 37. A receiving groove 45 is formed 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 card 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 center of the fixed ball close to the driving member 37, so as to be able to block the fixed ball from disengaging from the receiving groove 45. The elastic card 44 is made of an elastic material, and one end of the elastic card 44 close to the fixed ball can bend in a direction away from the driving member 37. The bending of the elastic card 44 can make it disengage from the fixed ball, thus canceling the limit on the driving member 37.

[0055] Figure 6 Reference Figure 6 and Figure 8

[0056] Figure 6 Reference Figure 6 and Figure 9 For the adjustable clamping assembly 42, it further includes a limiting ring 46. The receiving groove 45 is a circular groove, and the limiting ring 46 is correspondingly arranged as a circular ring. It is coaxially arranged inside the receiving groove 45 and is located on the side of the elastic card 44 close to the driving member 37. The outer side wall of the limiting ring 46 is in contact with and fixedly connected to the side wall of the receiving groove 45. Through the limiting ring 46, the elastic card 44 can be blocked from bending towards the driving member 37, thereby improving the stability of the elastic card 44 in limiting the fixed ball. Refer to Figure 6 and Figure 7 . The adjustable clamping assembly 42 further includes a linkage ring 47. The linkage ring 47 is a circular ring structure. It is coaxially arranged inside the limiting ring 46 and is in sliding fit with the limiting ring 46. The linkage ring 47 is located on the side of the elastic card 44 close to the driving member 37. A linkage rod 48 is fixedly arranged 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 plug pin 352. During the installation of the connector body 2, the base 351 is close to the vehicle body sheet metal, and the vehicle body sheet metal can abut against the linkage rod 48. As the base 351 moves, it drives the linkage rod 48 to move, and then drives the linkage ring 47 to move. The movement of the linkage ring 47 applies a force to the elastic card 44 to make it bend and disengage from the fixed ball, automatically canceling the limit on the fixed ball and realizing the rapid installation of the connector body 2. Refer to Figure 6 and Figure 8 . On the side of the driving member 37 close to the base 351, a driving assembly 5 is provided. The driving assembly 5 includes a fixed block 51 and a rotating block 52. Both the fixed block 51 and the rotating block 52 are cylindrical structures. The fixed block 51 is fixedly arranged on the side of the driving member 37 close to the base 351. The rotating block 52 is coaxially arranged with the fixed block 51, and the rotating block 52 is rotatably connected to the base 351 around its own axis. A spiral rising surface 53 is provided on the fixed block 51; the spiral rising surface 53 extends along a spiral line coaxial with the fixed block. A mating surface parallel to the spiral rising surface 53 is provided at the position corresponding to the spiral rising surface 53 on the rotating block 52. By rotating the rotating block 52, the cooperation between the spiral rising surface 53 extending along the spiral line and the mating surface can drive the driving member 37 to move, so that the driving member 37 can move away from the base 351, and further enable the abutting end of the movable abutting block 36 to tightly abut against the vehicle body sheet metal, and 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., on the side of the base 351 facing away from the driving member 37, a driving cavity 54 is provided, and one end of the rotating block 52 away from the driving member 37 extends into the driving cavity 54. On the side wall of the driving cavity 54, two partition plates 55 are provided, and the two partition plates 55 are evenly spaced along the circumferential direction of the driving cavity 54. The partition plates 55 are arranged radially along the rotating block 52, and the side of the partition plate 55 close to the rotating block 52 abuts against the rotating block 52 and is sealed. On the rotating block 52, two movable plates 56 are provided, and the two movable plates 56 are spaced along the circumferential direction of the rotating block 52 on 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.

[0057] Referring to Figure 6 and Figure 9 , when air is introduced between the partition plate 55 and the movable plate 56, the rotating block 52 can be driven to rotate under the action of gas pressure. Under the action of the partition plate 55 and the movable plate 56, the driving cavity 54 is divided into four cavities, and the four cavities are divided into two groups. Define the two groups of cavities as the locking cavity 57 and the unlocking cavity 58 respectively. The two locking cavities 57 are arranged corresponding to the gaps between the two contact cavities. When high-pressure gas is introduced into the locking cavity 57, the rotating block 52 can be driven to rotate forward (the rotating direction when the rotating block 52 drives the driving member 37 away from the base 351), so that the movable abutting block 36 can abut tightly against the vehicle body sheet metal. Here, the traditional screw or buckle 221 connection is avoided, thereby reducing the situation that non-professional staff disassemble the connector body 2, and reducing the situation that the wireless module is damaged due to non-professional disassembly.

[0058] Referring to Figure 6 and Figure 9 , two gas channels are provided on the base, one of the gas channels is communicated with the two locking cavities 57, and the other gas channel is communicated with the unlocking cavity 58. The gas channels form docking ports 59 on the side wall of the base, so as to facilitate the staff to use an air gun to inject high-pressure gas into the locking cavity 57 or the unlocking cavity 58.

[0059] Referring to Figure 9 and Figure 10 , a pressure-adaptive locking component 6 for limiting the rotation of the rotating block 52 is provided on the partition plate 55. The pressure-adaptive locking component 6 includes a locking plate 61 and a piston block 62. A sliding channel 64 is opened inside the partition plate 55, and the sliding cavity forms an opening on the side close to the rotating block 52. The locking plate 61 is slidably connected in 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, and the rotating block 52 is limited by the friction force between the locking plate 61 and the rotating block 52, so as to improve the stability of the connector body 2 after installation.

[0060] Referring to Figure 9 and Figure 10, the pressure - adaptive locking assembly 6 further includes a force - applying member 63. The force - applying member 63 is disposed in the sliding cavity and is used to keep the locking plate 61 moving towards the rotating block 52. In this embodiment, the force - applying member 63 is a spring. One end of the spring is welded to the side wall of the sliding cavity, and the other end is welded to the locking plate 61. Under the action of the force - applying member 63, the locking plate 61 can exert a certain acting force on the rotating block 52, so that a certain frictional force is maintained between the locking plate 61 and the rotating block 52.

[0061] Referring to Figure 9 and Figure 10 , the pressure - adaptive locking assembly 6 further includes a piston block 62. The piston block 62 is a rectangular block structure as a whole. A sliding channel 64 is provided on the partition plate 55 in a direction perpendicular to itself. The piston block 62 is slidably fitted in the sliding channel 64. The locking plate 61 is provided with a through - hole corresponding to the position of the piston block 62 for the piston block 62 to pass through the locking plate 61. Two driving inclined surfaces 65 are provided on the piston block 62, and the two driving inclined surfaces 65 are respectively provided corresponding to both sides in the thickness direction of the locking plate 61. The driving inclined surfaces 65 are inclined in a direction away from each other along the radial direction of the rotating block 52 from the side close to the rotating block 52 to the side far from the rotating block 52. When the piston block 62 moves, the driving inclined surfaces 65 can drive the locking plate 61 away from the rotating block 52.

[0062] Referring to Figure 9 and Figure 10 , during the actual operation process, when high - pressure gas is introduced into the locking cavity 57 or the release cavity 58, the pressure in the locking cavity 57 or the release cavity 58 increases, which can drive the piston block 62 to move, and then drive the locking plate 61 away from the rotating block 52, canceling the limit 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 cavity 57 or the release cavity 58 is cancelled, the spring rebounds, driving the locking plate 61 to abut against the rotating block 52, automatically limiting the rotation of the rotating block 52.

[0063] The implementation principle of an integrated wireless - transmission connector in an embodiment of this application is as follows: The insertion pin 352 is limited by the movable abutting block 36 connected movably, so that the overall large - scale installation process of the connector body 2 has better stability. By adjusting the degree of rotation of the movable abutting block 36, the stability after the installation of multiple connector bodies 2 can tend to be consistent, reducing the situation of inconsistent stability after the installation of the connector caused by the error of the body sheet - metal thickness or the production error of the movable abutting block 36.

[0064] The control of the driving movement is realized through the action of gas pressure, avoiding the situation that the connector body 2 can be disassembled by traditional tools, thus reducing the situation that non - professional personnel disassemble the wireless - transmission connector by themselves and affecting the wireless - transmission connector.

[0065] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
