Description

Technical Field

[0001] This application relates to the technical field of communication device connectivity, and in particular to a quick-plug adapter. Background Technology

[0002] In radio frequency (RF) transmission in radio communication, RF coaxial cables are used for signal transmission. Adapters are needed for signal switching between RF coaxial cables and between RF coaxial cables and devices. With the development of 5G and even future 6G communication technologies, higher requirements are placed on data transmission rates and stability. Adapters need to reduce signal attenuation and improve anti-interference capabilities under high-frequency signal transmission, while also meeting the requirements for low latency and high bandwidth, as well as ensuring rapid device connection and stable locking.

[0003] Some adapters in related technologies use threaded connections, requiring operators to tighten them multiple times to complete the connection. This necessitates significant time and effort for both installation and disassembly, making it inefficient for scenarios requiring frequent connection and disconnection. Other adapters are plug-in type, incorporating elastic elements such as claw springs. When adjacent plug-in adapters are plugged in, the claw springs lock them in place. Insufficient claw spring force can lead to unstable connections; excessive force requires considerable force for plugging and unplugging, causing inconvenience. Summary of the Invention

[0004] In order to improve the connection stability of the plug-in adapter while increasing the efficiency of plug-in connection, this application provides a quick plug-in adapter.

[0005] This application provides a quick-plug adapter, which adopts the following technical solution:

[0006] A quick-plug adapter includes a plug housing, a socket housing, an inner conductor, an insulating support, and a clamping and locking assembly; the plug housing and the socket housing are plugged into each other, the insulating support is disposed inside the plug housing and the socket housing, and the inner conductor is snapped into the insulating support;

[0007] The clamping and locking assembly includes a pressure block, a rotating rod, and a limiting block; the rotating rod is hinged to the plug housing, the pressure block is hinged to the rotating rod, and the limiting block is connected to the plug housing; when the rotating rod is rotated, the rotating rod drives the pressure block to move, so that the pressure block presses against the socket housing, the rotating rod moves into the limiting block, and the limiting block locks the position of the rotating rod.

[0008] By adopting the above technical solution, the plug housing and socket housing are first inserted and mated to form an initial connection. Then, rotating the rotating rod causes the pressure block to press against the socket housing, improving the connection stability between the plug and socket housings. The limiting block locks the position of the rotating rod, improving the stability of the rod's position after rotation, thereby ensuring a stable connection.

[0009] Optionally, one side of the pressure block is provided with a barbed tooth, which is used to abut against the socket housing.

[0010] By adopting the above technical solution, rotating the rotating rod drives the pressure block to move and press against the socket housing, so that the reverse teeth abut against the socket housing, increasing the friction and thus improving the connection stability between the plug housing and the socket housing.

[0011] Optionally, the limiting block is provided with a guide surface and a limiting groove is formed in the limiting block; the rotating rod is rotated, the rotating rod moves along the guide surface and deforms, and after passing the guide surface, the rotating rod recovers its deformation and is engaged in the limiting groove.

[0012] By adopting the above technical solution, rotating the rotating rod causes the end of the rotating rod to slide along the guide surface and deform. After passing the guide surface, it recovers its deformation and moves into the limiting groove. The limiting groove locks the position of the rotating rod, which improves the stability of the rotating rod's position after rotation, thereby helping to improve the connection stability between the plug housing and the socket housing.

[0013] Optionally, the plug housing is connected to an elastic component, the socket housing is engaged with the elastic component, and the elastic component and the clamping locking component clamp the socket housing.

[0014] By adopting the above technical solution, the plug housing and socket housing are plugged in and engaged, the elastic component is snapped into the socket housing, and the elastic component and the clamping and locking component together clamp the socket housing, which can further improve the connection stability between the plug housing and the socket housing.

[0015] Optionally, the elastic component includes a support sealing ring and a claw spring, the support sealing ring being connected to the plug housing, the claw spring being connected to the plug housing, and the claw spring engaging with the socket housing.

[0016] By adopting the above technical solution, when the plug housing and socket housing are inserted, the socket housing engages with the claw spring, thereby enabling an initial connection between the plug housing and the socket housing. The supporting sealing ring improves the sealing performance between the plug housing and the socket housing, thereby reducing the possibility of moisture entering the interior from between the plug housing and the socket housing.

[0017] Optionally, an end connection assembly is provided between the plug housing and the socket housing. The end connection assembly and the clamping and locking assembly are located at opposite ends of the plug housing, and the plug housing and the socket housing are engaged by the end connection assembly.

[0018] By adopting the above technical solution, clamping and locking components and end connection components are respectively provided at both ends of the plug housing, so that the socket housing can be connected to both ends of the plug housing according to the needs, thereby improving the flexibility of the connection.

[0019] Optionally, the end connection assembly includes a connecting inner shell and a connecting outer shell, the connecting inner shell being sleeved on the outside of the insulating support, and the connecting outer shell being sleeved on the outside of the plug housing and the socket housing.

[0020] By adopting the above technical solution, a connecting outer shell is fitted on the outside of the plug housing and the socket housing, and a connecting inner shell is fitted on the outside of the insulating support body, thereby enabling the plug housing and the socket housing to be plugged in.

[0021] Optionally, the connecting housing is fixedly connected to the plug housing, and the end connecting assembly further includes a locking ball and a sliding locking shell. The connecting housing has a receiving hole, and the locking ball is embedded in the receiving hole. The sliding locking shell is slidably connected to the connecting housing. The socket housing has a first receiving groove, and the sliding locking shell has a second receiving groove.

[0022] By sliding the sliding locking shell, the second receiving groove is misaligned with the receiving hole, and the sliding locking shell pushes the locking ball to protrude into the first receiving groove, so that the locking ball locks the position of the socket housing;

[0023] Slide the sliding locking shell to align the second receiving groove with the receiving hole, move the socket housing, and the socket housing will push the locking ball to protrude into the second receiving groove, so that the locking ball releases the lock on the socket housing.

[0024] By adopting the above technical solution, when the sliding locking shell is slid down so that the second receiving groove is misaligned with the receiving hole, the locking ball is pushed to protrude into the first receiving groove, which can lock the position of the socket shell and improve the connection stability between the plug shell and the socket shell. When the sliding locking shell is slid down in the opposite direction so that the second receiving groove is aligned with the receiving hole, the socket shell is pulled out, and the socket shell pushes the locking ball to protrude into the second receiving groove, thereby releasing the lock on the socket shell and facilitating the separation of the plug shell and the socket shell.

[0025] Optionally, the end connection assembly further includes a transmission rod, which is hinged to the rotating rod and the sliding locking housing respectively, and the rotating rod drives the sliding locking housing to slide through the transmission rod.

[0026] By adopting the above technical solution, when the rotating rod rotates, it can drive the sliding locking shell to slide through the transmission rod, so that the second receiving groove is misaligned or aligned with the receiving hole, thereby locking or unlocking the socket shell by the locking ball, which is beneficial to improving the connection stability between the plug shell and the socket shell, and also facilitates the disconnection of the plug shell and the socket shell.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. Push the rotating rod, which drives the pressure block to move, causing the pressure block to press against the socket housing. The countersunk teeth on one side of the pressure block abut against the socket housing to increase the friction. The rotating rod moves to the locked position inside the limit block, which effectively improves the connection stability between the plug housing and the socket housing from this side.

[0029] 2. When the rotating rod rotates, it drives the sliding locking shell to slide through the transmission rod, causing the second receiving groove to be misaligned with the receiving hole. The sliding locking shell pushes the locking ball to protrude into the first receiving groove. The locking ball locks the position of the socket shell, improving the connection stability between the plug shell and the socket shell.

[0030] 3. When it is necessary to disconnect, reverse the operation of the rotating rod. The rotating rod unlocks and drives the pressure block to loosen the socket housing. At the same time, the rotating rod drives the sliding locking housing to slide through the transmission rod so that the second receiving groove is aligned with the receiving hole. Then pull out the socket housing. The socket housing pushes the locking ball to protrude into the second receiving groove. The locking ball releases the lock on the socket housing, making it easy to disconnect the plug housing from the socket housing. Attached Figure Description

[0042] The following combination Figures 1 to 10 This application will be described in further detail.

[0043] Example 1:

[0044] Embodiment 1 of this application provides a quick-plug adapter.

[0045] refer to Figure 1 and Figure 2 A quick-connect adapter includes a plug housing 1, a socket housing 2, an inner conductor 3, an insulating support 4, an elastic component 5, and an end connection component 7. The two ends of the plug housing 1 are a first plug housing end 1a and a second plug housing end 1b, respectively. The two ends of the socket housing 2 are a first socket housing end 2a and a second socket housing end 2b, respectively. The second plug housing end 1b can be plugged into the first socket housing end 2a, and the first plug housing end 1a can be plugged into the second socket housing end 2b, thereby improving the flexibility of plugging and unplugging.

[0046] refer to Figure 1 and Figure 2The insulating support 4 is snapped between the second end 1b of the plug housing and the first end 2a of the socket housing. The inner conductor 3 is snapped with the insulating support 4. Both the inner conductor 3 and the insulating support 4 are located inside the plug housing 1 and the socket housing 2. The insulating support 4 provides support for the inner conductor 3, so that the inner conductor 3 is separated from the plug housing 1 and the socket housing 2 respectively, so that a cavity 11 is formed between the inner conductor 3 and the plug housing 1 and the socket housing 2 respectively.

[0047] refer to Figure 1 and Figure 2 The end connection assembly 7 includes a connecting inner shell 71 and a connecting outer shell 72. The connecting inner shell 71 is sleeved on the outside of the insulating support 4, and the connecting outer shell 72 is sleeved on the outside of the second end 1b of the plug housing and the first end 2a of the socket housing. The plug housing 1 and the socket housing 2 are both engaged with the connecting inner shell 71 and the connecting outer shell 72, which facilitates the connection between the second end 1b of the plug housing and the first end 2a of the socket housing.

[0048] refer to Figure 1 and Figure 2 The elastic component 5 is located inside the first end 1a of the plug housing. The elastic component 5 and the end connecting component 7 are located at the two ends of the plug housing 1, respectively. The elastic component 5 includes a supporting sealing ring 51 and a claw spring 52. The supporting sealing ring 51 is fixedly connected to the inner side of the first end 1a of the plug housing, and the claw spring 52 is fixedly connected to the inner side of the first end 1a of the plug housing. When the second end 2b of the socket housing is inserted into the first end 1a of the plug housing, the claw spring 52 applies a spring force to the second end 2b of the socket housing, thereby facilitating the connection between the second end 2b of the socket housing and the first end 1a of the plug housing. The supporting sealing ring 51 can improve the sealing between the first end 1a of the plug housing and the second end 2b of the socket housing, reducing the possibility of moisture entering the interior from between the first end 1a of the plug housing and the second end 2b of the socket housing.

[0049] The implementation principle of a quick-plug adapter in Embodiment 1 of this application is as follows: the second end 1b of the plug housing and the first end 2a of the socket housing are respectively engaged with the inner shell 71 and the outer shell 72, thereby connecting the second end 1b of the plug housing and the first end 2a of the socket housing. When it is necessary to connect the second end 2b of the socket housing to the first end 1a of the plug housing, the second end 2b of the socket housing is inserted into the first end 1a of the plug housing, so that the claw spring 52 engages with the second end 2b of the socket housing, thereby connecting the second end 2b of the socket housing to the first end 1a of the plug housing. The second end 1b of the plug housing can be inserted and engaged with the first end 2a of the socket housing, and the first end 1a of the plug housing can be inserted and engaged with the second end 2b of the socket housing. Furthermore, they can be inserted and engaged in the order of "socket housing 2, plug housing 1, and socket housing 2", and also in the order of "plug housing 1, socket housing 2, plug housing 1, and socket housing 2", thereby improving the flexibility of insertion.

[0050] Example 2:

[0051] Embodiment 2 of this application provides a quick-plug adapter. The difference between Embodiment 2 and Embodiment 1 is that:

[0052] refer to Figure 3 and Figure 4 In this embodiment, the plug housing 1, socket housing 2, plug housing 1 and socket housing 2 are connected in the order of insertion. The first end 1a of the plug housing is provided with a clamping and locking assembly 6, which includes a pressure block 61, a countertooth 62, a rotating rod 63 and a limiting block 64.

[0053] refer to Figure 5 and Figure 6 The rotating rod 63 is hinged to the plug housing 1, and the end of the rotating rod 63 is hinged to the pressure block 61. Through the dimensional design of the claw spring 52 and the second end 2b of the socket housing, after the second end 2b of the socket housing is inserted into the first end 1a of the plug housing, the claw spring 52 applies a small elastic force to the second end 2b of the socket housing, thus enabling the second end 2b of the socket housing to be inserted into the first end 1a of the plug housing with a small force. The elastic force provided by the claw spring 52 allows for an initial connection between the plug housing 1 and the socket housing 2. Subsequently, the rotating rod 63 is rotated, causing the pressure block 61 to move, causing the pressure block 61 to press against the second end 2b of the socket housing. At this time, the pressure block 61 and the claw spring 52 are located on the inner and outer sides of the second end 2b of the socket housing, respectively. The pressure block 61 and the claw spring 52 clamp the second end 2b of the socket housing, improving the stability of the connection between the second end 2b of the socket housing and the first end 1a of the plug housing.

[0054] refer to Figure 5 and Figure 6 The reverse tooth 62 is fixedly connected to the side of the pressure block 61 near the claw spring 52. The reverse tooth 62 can increase the friction force and further improve the positional stability between the pressure block 61 and the second end 2b of the socket housing.

[0055] refer to Figure 5 and Figure 6 The limiting block 64 is fixedly connected to the outside of the plug housing 1. A guide surface 641 is provided on one side of the limiting block 64, and a limiting groove 642 is provided in the limiting block 64. When the rotating rod 63 is rotated, the rotating rod 63 contacts the guide surface 641 of the limiting block 64 and moves along the guide surface 641, causing the rotating rod 63 to deform. After the rotating rod 63 passes the guide surface 641, the rotating rod 63 returns to its deformed state and is locked in the limiting groove 642, thereby locking the position of the rotating rod 63. At this time, the rotating rod 63 drives the pressure block 61 to press the second end 2b of the socket housing, thereby improving the connection stability between the second end 2b of the socket housing and the first end 1a of the plug housing.

[0056] Example 3:

[0057] Embodiment 3 of this application provides a quick-plug adapter. The difference between Embodiment 3 and Embodiment 2 is that:

[0058] refer to Figure 7 and Figure 8 The end connection assembly 7 further includes a locking ball 73, a sliding locking shell 74, and a transmission rod 75. The sliding locking shell 74 is sleeved on the outside of the connecting shell 72, and the sliding locking shell 74 is slidably connected to the connecting shell 72. In this embodiment, the connecting shell 72 is fixedly connected to the plug shell 1. The connecting shell 72 has a receiving hole 721, and the locking ball 73 is embedded in the receiving hole 721, with the locking ball 73 protruding from the receiving hole 721.

[0059] refer to Figure 8 and Figure 9 A first receiving groove 21 is provided on the outer side of the first end 2a of the socket housing, and a second receiving groove 741 is provided on the inner side of the sliding locking shell 74. By pushing the sliding locking shell 74 to slide, the second receiving groove 741 is aligned with the receiving hole 721. Then, the first end 2a of the socket housing is inserted into the connecting shell 72. The first end 2a of the socket housing pushes the locking ball 73 to move, causing a portion of the locking ball 73 to protrude from the second receiving groove 741. At this time, the locking ball 73 releases the locking of the first end 2a of the socket housing, facilitating the insertion of the first end 2a of the socket housing into the connecting shell 72, or facilitating the removal of the first end 2a of the socket housing. Furthermore, after the first end 2a of the socket housing is fully inserted into the connecting shell 72, the first receiving groove 21 is aligned with the receiving hole 721.

[0060] refer to Figure 8 and Figure 9 When it is necessary to lock the position of the socket housing 2, the sliding locking shell 74 is pushed to move away from the socket housing 2, so that the second receiving groove 741 is misaligned with the receiving hole 721. The sliding locking shell 74 pushes the locking ball 73 to move, so that part of the locking ball 73 protrudes into the first receiving groove 21. At this time, the locking ball 73 locks the socket housing 2, improving the connection stability between the second end 1b of the plug housing and the first end 2a of the socket housing.

[0061] refer to Figure 7 and Figure 8 In this embodiment, through size design, when the first end 2a of the socket housing is inserted into the connecting inner shell 71 and the connecting outer shell 72 respectively, the connecting inner shell 71 and the connecting outer shell 72 apply a small clamping force to the first end 2a of the socket housing. This facilitates the insertion of the first end 2a of the socket housing between the connecting inner shell 71 and the connecting outer shell 72 with a small force, thus enabling an initial connection between the plug housing 1 and the socket housing 2. Subsequently, the sliding locking shell 74 is slid, causing the locking ball 73 to protrude from the first receiving groove 21, thereby locking the socket housing 2 and improving the stability of the connection between the plug housing 1 and the socket housing 2.

[0062] refer to Figure 8 and Figure 9 In this embodiment, the diameter of the receiving hole 721 on the side near the sliding locking shell 74 is larger than the diameter on the other side, so that the locking ball 73 can protrude from the receiving hole 721 toward the inside of the connecting shell 72 without disengaging from the receiving hole 721.

[0063] Example 4:

[0064] Embodiment 4 of this application provides a quick-plug adapter. The difference between Embodiment 4 and Embodiment 3 is that:

[0065] refer to Figure 10 The end connecting assembly 7 also includes a transmission rod 75, which is hinged to the sliding locking shell 74 and the rotating rod 63 respectively. After the socket shells 2 are initially inserted into both ends of the plug shell 1, the rotating rod 63 is rotated. The rotating rod 63 causes the pressure block 61 to press one of the socket shells 2, and on the other hand, it causes the sliding locking shell 74 to slide, causing the second receiving groove 741 to misalign with the receiving hole 721, so that the locking ball 73 locks the other socket shell 2, thereby quickly locking both socket shells 2 onto the plug shell 1 simultaneously. The transmission rod 75 has a certain elasticity, and during the process of the rotating rod 63 being engaged in the limiting block 64, the transmission rod 75 undergoes a certain deformation with the rotating rod 63.

[0066] refer to Figure 10 When it is necessary to remove the two socket housings 2 from the plug housing 1, the rotating rod 63 is rotated in the opposite direction. The rotating rod 63 causes the pressure block 61 to loosen one of the socket housings 2. On the other hand, the rotating rod 63 causes the sliding locking housing 74 to slide, so that the second receiving groove 741 is aligned with the receiving hole 721, and the locking ball 73 is released from locking the other socket housing 2, thereby facilitating the quick removal of the two socket housings 2 from the plug housing 1.

[0067] 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.
