Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication equipment connection, and in particular to a quick plug-in adapter. BACKGROUND

[0002] In the radio frequency transmission of radio communication, radio frequency coaxial cables are used for signal transmission, and adapters are needed for signal switching between radio frequency coaxial cables and between radio frequency coaxial cables and equipment. With the development of 5G and even future 6G communication technology, higher requirements are put forward for data transmission rate and stability. The adapter needs to reduce signal attenuation and improve anti-interference ability under high-frequency signal transmission, and also needs to meet the requirements of low delay and high bandwidth, and meet the requirements of fast connection and stable locking of the equipment.

[0003] In the related art, some adapters are connected by threads, and it takes multiple turns for the operator to complete the connection. It takes a lot of time and effort to install and disassemble, and for some scenes that need to be connected and disconnected frequently, the efficiency is very low. Some adapters are plug-in adapters, and the plug-in adapter is provided with elastic members such as claw springs. After the adjacent plug-in adapters are inserted, the adjacent plug-in adapters are locked by the elastic force of the claw springs. If the elastic force of the claw spring is small, it is easy to cause unstable connection; if the elastic force of the claw spring is large, it will cause the plug-in to be difficult, thereby causing the inconvenience of plug-in operation.

[0007] Optionally, the pressing block is provided with a reverse tooth on one side, and the reverse tooth is used to abut against the socket shell.

[0008] By adopting the technical scheme, the rotating rod drives the pressing block to move and abut against the socket shell, so that the reverse tooth abuts against the socket shell, thereby increasing the friction, and thereby improving the connection stability of the plug shell and the socket shell.

[0009] Optionally, the limiting block is provided with a guide surface, and the limiting block is provided with a limiting groove; the rotating rod is rotated, the rotating rod moves along the guide surface and is deformed, and after the rotating rod passes through the guide surface, the rotating rod restores the deformation and is clamped in the limiting groove.

[0010] By adopting the technical scheme, the rotating rod is rotated to make the end of the rotating rod slide along the guide surface and be deformed, and after passing through the guide surface, the end of the rotating rod restores the deformation and moves into the limiting groove, and the position of the rotating rod is locked by the limiting groove, thereby improving the stability of the position of the rotating rod after rotation, and thereby being beneficial to improving the connection stability of the plug shell and the socket shell.

[0011] Optionally, the plug shell is connected with an elastic assembly, the socket shell is clamped with the elastic assembly, and the elastic assembly clamps the socket shell together with the clamping and locking assembly.

[0012] By adopting the technical scheme, the plug shell and the socket shell are plugged and fitted, the elastic assembly is clamped with the socket shell, and the elastic assembly and the clamping and locking assembly clamp the socket shell together, thereby further improving the connection stability of the plug shell and the socket shell.

[0014] By adopting the technical scheme, when the plug shell and the socket shell are plugged, the socket shell is clamped with the claw spring, thereby enabling the plug shell and the socket shell to be preliminarily connected. The supporting sealing ring improves the sealing between the plug shell and the socket shell, thereby reducing the situation that moisture enters the inside from between the plug shell and the socket shell.

[0015] 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.

[0016] 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.

[0017] 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.

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. 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; 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.

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.

[0021] 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.

[0022] 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.

[0023] In summary, this application includes at least one of the following beneficial effects: 1. Push the rotating rod, which drives the pressure block to move, causing the pressure block to press against the socket housing.

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. 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. 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

[0026] The following combination Figures 1 to 10 This application will be described in further detail.

[0027] Example 1:

[0028] Embodiment 1 of this application provides a quick-plug adapter.

[0029] 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.

[0030] refer to Figure 1 and Figure 2 The 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.

[0031] refer to Figure 1 and Figure 2The 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.

[0032] 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.

[0033] 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.

[0034] Example 2:

[0035] Embodiment 2 of this application provides a quick-plug adapter. The difference between Embodiment 2 and Embodiment 1 is that: refer to Figure 3 and Figure 4In 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Example 3:

[0040] Embodiment 3 of this application provides a quick-plug adapter. The difference between Embodiment 3 and Embodiment 2 is that: refer to Figure 7 and Figure 8The 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] refer to Figure 8 and Figure 9In 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.

[0045] Example 4:

[0046] Embodiment 4 of this application provides a quick-plug adapter. The difference between Embodiment 4 and Embodiment 3 is that: 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.

[0047] 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.

[0048] 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.
