[0002] With the rapid development of electronic technology, the demand for connection between electronic devices is also increasing. As a key component for connecting electronic devices, the performance and stability of connectors directly affect the operation of the entire electronic system.

[0003] At present, most of the coaxial connectors on the market are single-channel structures, and their waterproof performance needs to be improved. Against the background of the growing demand for multi-channel connections, how to provide a multi-channel coaxial connector with excellent waterproof performance has become an urgent problem to be solved in the current technical field. Existing coaxial connectors have certain limitations in terms of waterproof performance and often cannot meet the use requirements in harsh environments. In addition, the single-channel design also limits the efficiency and scalability of data transmission. Therefore, it is particularly important to develop a coaxial connector that has both multi-channel and waterproof performance. Utility Model Content

[0004] In order to solve the above problems, the present invention proposes a multi-channel coaxial waterproof female connector, which can have both multi-channel and waterproof performances, and can improve data transmission efficiency and scalability.

[0037] The following is combined with Figure 1-2 This application is described in further detail.

[0038] The terms used in this application are only for the purpose of describing specific embodiments, and are not intended to limit this application. Unless otherwise defined, the technical language or scientific terms used in this application should be the usual meaning understood by a technician in the field to which this application belongs. The "first", "second", "third" and similar words used in this application do not represent any order, quantity or importance, but are only used to distinguish different components.

[0039] The present application embodiment discloses a multi-channel coaxial waterproof female connector. Figure 1 and Figure 2 The multi-channel coaxial waterproof female connector includes: a coaxial contact assembly 10, a fixing member 20, an outer shell 30, a front shell 40, a first sealing member 50, a second sealing member 60, a rear cover 70 and a third sealing member 80.

[0040] The fixing member 20 is provided with a plurality of first channel holes 21 for passing through a plurality of coaxial contact components 10. The outer shell 30 is sleeved on the outer side of the fixing member 20, and the front shell 40 is sleeved on one end of the outer shell 30, i.e., the front end, and the first sealing member 50 is sleeved on the front shell 40 and accommodated in the outer shell 30, so that the front end can be waterproof and dustproof.

[0041] The second sealing member 60 is provided with a plurality of second channel holes 61, which are used to sleeve the end of the plurality of coaxial contact assemblies 10 away from the front housing 40, and can activate the waterproof effect inside while fixing the plurality of coaxial contact assemblies 10. The rear cover 70 is sleeved on the end of the outer housing 30 away from the front housing 40, that is, the rear end, and cooperates with the third sealing member 80 to be sleeved on the rear cover 70 and located in the outer housing 30, so that the rear end can be waterproof and dustproof.

[0042] Thus, this embodiment can realize the simultaneous connection of multiple coaxial contact components 10 through a multi-channel design (i.e., multiple first channel holes 21 are provided on the fixing member 20 for multiple coaxial contact components 10 to pass through), thereby improving data transmission efficiency and scalability. At the same time, by providing multiple seals (i.e., the first seal 50, the second seal 60 and the third seal 80), the intrusion of moisture and dust can be effectively prevented, thereby ensuring the stability and durability of the connector.

[0043] It is worth mentioning that the outer sides of the first seal 50, the second seal 60 and the third seal 80 are all threaded. The threaded setting can increase the friction between the seal and the outer shell 30 or the coaxial contact assembly 10 to further improve the sealing effect, thereby better preventing the intrusion of moisture and dust.

[0044] Reference Figure 3 A first flange 31 and a second flange 32 are provided on the inner side of the outer shell 30 , and the fixing member 20 is located between the first flange 31 and the second flange 32 .

[0045] One end of the fixing member 20 abuts against the first convex edge 31, and a stopper 22 extending outward is provided around the other end of the fixing member 20. The stopper 22 is provided in plurality and abuts against the second convex edge 32 respectively. In this way, the fixing member 20 can be effectively prevented from moving in the outer shell 30 by abutting against the second convex edge 32 by a plurality of stoppers 22, thereby further enhancing the structural stability of the connector. The shape of the stopper 22 can be as follows: Figure 2 as shown in .

[0046] Reference Figure 3 and Figure 4 One end of the rear cover body 70 is embedded in the outer shell 30 and is located in the accommodating space 23 formed by the stopper 22 and the fixing member 20 , and abuts against the stopper 22 .

[0047] Among them, the design of the rear cover body 70 abutting the anti-retraction member 22 can prevent the risk of the retraction member 22 falling down after long-term use, and at the same time make the connection between the rear cover body 70, the fixing member 20 and the outer shell 30 tighter, thereby improving the overall structural strength.

[0048] Reference Figure 2 and Figure 4 The rear cover 70 is located in the accommodating space 23 and one end thereof is provided with a groove. Figure 2 As shown, a plurality of grooves are provided corresponding to the plurality of retaining members 22, so that the rear cover body 70 can be conveniently embedded in the accommodating space 23, and a certain rotation limit can be performed on the retaining members 22, thereby improving the stability inside the connector, and also making the connection between the rear cover body 70, the fixing member 20 and the outer shell 30 tighter, thereby improving the overall structural strength.

[0049] Reference Figure 2 and Figure 5 In order to facilitate the connection between the front housing 40 and the outer housing 30, a plurality of first buckle grooves 41 are provided on the circumference of the front housing 40, and a plurality of first buckle members 33 are provided in the outer housing 30 corresponding to the plurality of first buckle grooves 41. By means of the buckle connection between the first buckle members 33 and the first buckle grooves 41, not only a stable connection between the front housing 40 and the outer housing 30 can be achieved, but also the assembly and disassembly of the two can be facilitated.

[0050] See also Figure 2 and Figure 4 In order to facilitate the connection between the rear cover 70 and the outer shell 30, a plurality of second buckle grooves 71 are provided on the rear cover 70, and a plurality of second buckle members 34 are provided on the outer shell 30 corresponding to the plurality of second buckle grooves 71. In this way, through the buckle connection between the second buckle grooves 71 and the second buckle members 34, not only can a stable connection between the rear cover 70 and the outer shell 30 be achieved, but also the assembly and disassembly of the two can be facilitated.

[0051] Reference Figure 2 and Figure 4 In this embodiment, the connector further includes a snap-fitting member 90 for penetrating the fixing member 20 and snapping into the coaxial contact assembly 10 .

[0052] The fixing member 20 is provided with through grooves 24 on opposite sides corresponding to the engaging members 90 , which can ensure the stability of the position of the coaxial contact assembly 10 in the fixing member 20 when the engaging members 90 are plugged in, and prevent it from loosening or falling off.

[0053] In addition, refer to Figure 2 and Figure 4 In this embodiment, the connector further includes a self-locking member 100 , one end of which is embedded in the outer shell 30 , and the other end is set as an elastic wall 101 , and a limiting groove 102 is set on the elastic wall 101 .

[0054] The setting of the limiting groove 102 allows the male connector to be buckled, and the design of the self-locking member 100 enables the connector to have a self-locking function during the connection process, thereby improving the reliability and safety of the connection.

[0055] Reference Figure 5 In order to prevent the self-locking member 100 from being displaced or falling off from the outer shell 30 during use, a blocking member 35 is provided on the outer shell 30, and one end of the corresponding elastic wall 101 is bent relative to the blocking member 35. The blocking member 35 and the bent elastic wall 101 cooperate with each other, so that the self-locking member 100 can better maintain its position stability when subjected to external force, thereby enhancing the self-locking effect.

[0056] To summarize, the multi-channel coaxial waterproof female connector disclosed in the embodiment of the present application realizes the simultaneous connection of multiple coaxial contact components 10 by adopting a multi-channel design, thereby improving data transmission efficiency and scalability; by setting up multiple seals and waterproof structures, it effectively prevents the intrusion of moisture and dust, thereby ensuring the stability and durability of the connector.
