As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "above", "the" and "this" are intended to also include plural expressions, unless there is a clear indication to the contrary in the context. It should also be understood that the term "and / or" used in the present application refers to and includes any or all possible combinations of one or more listed items.
[0033] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. 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 single-cell waterproof Mini Fakra line-end female connector, including a female housing 10, a first waterproof component 20, a coaxial contact assembly 30, a second waterproof component 40 and a rear plug 50.
[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] 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. The coaxial contact assembly 30 is set as one, that is, the female connector is a single-hole (single-cell) structure. In this embodiment, the coaxial contact assembly 30 is an existing related technology and is not limited here.
[0038] The second waterproof member 40 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 40 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 40 are provided together to improve the waterproof performance of the female connector.
[0039] The rear plug 50 is used to abut against the second waterproof member 40 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.
[0040] In addition, in this embodiment, it is worth mentioning that the overall structure of the female connector involves fewer parts, which can reduce the cost of the female connector and simplify the overall assembly.
[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.
[0042] See also Figure 2 and Figure 3 An external thread 41 is provided on the outer side of the second waterproof component 40, and an internal thread 12 is provided on the inner side of the female shell 10 at one end away from the plug-in port 11. When the second waterproof component 40 is embedded into the female shell 10 by external force, the external thread 41 and the internal thread 12 are staggered and interlocked, and the coaxial contact component 30 passes through the second waterproof component 40 and is accommodated in the female shell 10, thereby achieving a sealing and waterproof effect on the coaxial contact component 30.
[0043] For example, during assembly, the coaxial contact component 30 can be first passed through the second waterproof component 40 to be accommodated in the female shell 10, and then the second waterproof component 40 is pushed into (or screwed with external force) the female shell 10 by external force to achieve the assembly of the female connector, thereby facilitating the assembly of the female connector with this structure.
[0044] See also Figure 3 A retaining member 13 is provided in the female housing 10 for abutting against the coaxial contact assembly 30 located in the female housing 10 to prevent the coaxial contact assembly 30 from moving in the female housing 10 when the male connector is plugged in or out.
[0045] The stopper 13 is a petal-shaped integrated coaxial contact component 30, and the coaxial contact component 30 is provided with a first convex edge 31 on the outer side of the stopper 13. The engagement state of the coaxial contact component 30 can be as shown in FIG. Figure 3As shown in , the stability of the coaxial contact assembly 30 in the female connector housing 10 can be further increased.
[0046] See also Figure 2 In order to facilitate the rear plug 50 to be mounted on the female shell 10, a snap-fit groove 51 is provided on the rear plug 50, and corresponding buckles 14 are provided on both sides of the female shell 10. The rear plug 50 can be snap-fitted on the buckles 14 of the female shell 10 through the snap-fit groove 51 to realize the assembly of the rear plug 50 on the female shell 10, thereby facilitating the assembly of the female connector.
[0047] Among them, a guide groove 52 is also provided on the rear plug 50, and a second convex edge 15 is provided on both sides of the corresponding female shell 10. The rear plug 50 can slide into the second convex edge 15 through the guide groove 52, so that the snap-fit groove 51 on the rear plug 50 and the buckle 14 on the female shell 10 can be snapped together to play a guiding role, which is more convenient for the assembly of the female connector.
[0048] In summary, the embodiment of the present application discloses a single-cell waterproof Mini Fakra line-end female connector, in which a first waterproof component 20 is arranged in the plug port 11, and a second waterproof component 40 is arranged on the end away from the plug port 11, the coaxial contact assembly 30 is accommodated in the female housing 10 through the second waterproof component 40, and the rear plug 50 abuts against the second waterproof component 40 and is sleeved on the female housing 10, so that a waterproof effect can be achieved at both ends of the female housing 10, so as to improve the safety of the automotive RF connector during use; it can avoid the displacement of the first waterproof component 20 when the male connector is connected, The waterproof effect of the plug-in port 11 is affected, thereby improving the waterproof performance of the female connector; an external thread 41 is set on the second waterproof component 40, and an internal thread 12 is set on the inner side of the female shell 10. The second waterproof component 40 can be screwed by external force through the setting of the external thread 41 and the internal thread 12 to achieve the second waterproof component 40 and the female shell 10. The coaxial contact component 30 passes through the second waterproof component 40 and is accommodated in the female shell 10, so that the coaxial contact component 30 can be waterproofed and the assembly of the female connector is also convenient.
[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
