Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0034] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0035] See also Figure 1 and Figure 2 The embodiment of the present application discloses a twin waterproof Mini Fakra line end female connector, including a female housing 10, a first waterproof component 20, a coaxial contact assembly 30, a clamping assembly 40, a second waterproof component 50 and a rear plug 60.

[0036] One end of the female housing 10 is provided with a plug port 11 for plugging in the male connector. The first waterproof member 20 is located in the plug port 11 and can be used to abut against the male connector to achieve a waterproof effect at the plug port 11. In addition, the first waterproof member 20 is made of silicone and can play an elastic buffering role when the male connector is connected.

[0037] See also Figure 2 and Figure 3 The coaxial contact assembly 30 is located in the female housing 10, and the male connector can contact the coaxial contact assembly 30 through the plug port 11 to achieve line conduction. Two coaxial contact assemblies 30 are provided, that is, the female connector is a two-hole (twin) structure. In this embodiment, the coaxial contact assembly 30 is an existing related technology and is not limited here.

[0038] The clamping assembly 40 is located in the female housing 10 and is used to clamp the two coaxial contact assemblies 30 to clamp and limit the coaxial contact assemblies 30 so that the two coaxial contact assemblies 30 are firmly fixed in the female housing 10 and the structural tightness of the female connector is improved.

[0039] The second waterproof member 50 is made of silicone and is sleeved on the end of the coaxial contact assembly 30 away from the plug port 11, that is, the coaxial contact assembly 30 passes through the second waterproof member 50 and is accommodated in the female housing 10, which can achieve a waterproof effect at the end of the female housing 10 away from the plug port 11. In this way, the first waterproof member 20 and the second waterproof member 50 are provided together to improve the waterproof performance of the female connector.

[0040] The rear plug 60 is used to abut against the second waterproof member 50 and is assembled on the end of the female housing 10 away from the plug port 11, thereby completing the assembly of the female connector.

[0041] Specifically, the outer shape of the female housing 10 can be as follows: Figure 2 The first waterproof member 20 and the female housing 10 are integrally formed to prevent the first waterproof member 20 from shifting when the male connector is connected, thereby affecting the waterproof effect of the plug port 11 and improving the waterproof performance of the female connector.
