Description
Technical Field
[0001] This utility model relates to the field of long-bodied male and female connector technology, specifically a long-bodied male and female connector waterproof structure. Background Technology
[0002] Long-body male and female connectors are a specially designed type of connector, primarily used in applications requiring longer connection distances.
[0003] For example, the Chinese authorized patent with publication number CN212062862U (A connector quick-plug port structure) includes a male and a female connector. The male connector includes a male connector shell, a male connector body, a male connector insulator, and a male connector guide pin. The female connector includes a female connector shell, a female connector body, a female connector elastic outer conductor, a female connector insulator, and a female connector guide pin. When the male and female connectors are connected, the male connector body is inserted between the female connector body and the female connector elastic outer conductor. The curling spring elastically clamps the male connector body. At the same time, the female connector body and the female connector insulator are inserted into the male connector body. The male connector guide pin is inserted into the female connector insulator and connects to the female connector guide pin, thereby realizing a quick-plug connection between the male and female connectors. The assembly is simple and fast, and the size is compact and small, meeting the miniaturization requirements. Moreover, neither the male nor the female connector guide pin is exposed and is well protected to prevent damage and deformation.
[0004] However, most existing long-bodied male and female connectors achieve waterproofing by adding an external locking structure, which is easily damaged by bumps and has low security. Furthermore, they are prone to aging when exposed to the outside, resulting in poor waterproofing performance. Therefore, they do not meet the current needs. In response, we propose a long-bodied male and female connector waterproofing structure. Utility Model Content
[0005] The purpose of this utility model is to provide a waterproof structure for long-bodied male and female connectors, in order to solve the problems mentioned in the background art, that most existing long-bodied male and female connectors rely on external locking structures for waterproofing, which are easily damaged by bumps and have low safety, and are also prone to aging when exposed to the outside, resulting in poor waterproofing effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a long-bodied waterproof male and female head structure, comprising: a male head shell, a female head shell at one end of the male head shell, a connecting seat at the other end of both the male head shell and the female head shell, an elastic inner ring inside the female head shell, a connecting slot between the outer wall of the elastic inner ring and the inner wall of the female head shell, and a sealing ring inside the connecting slot, with the sealing ring fitted over the elastic inner ring.
[0007] Preferably, a limiting triangular seat is provided on one side of the elastic inner ring, and the limiting triangular seat is located on the inner wall of the female head shell, integrally formed with the female head shell, and multiple limiting triangular seats are provided.
[0008] Preferably, the inner elastic ring has an installation hole inside, the male connector housing has a long pin connector inside, the long pin connector is inserted into the installation hole, and one end of the male connector housing is inserted into the connection slot.
[0009] Preferably, the upper end of the female head shell is provided with a snap-fit plate, one end of which is provided with a snap-fit notch, and the upper end of the male head shell is provided with a snap-fit bracket, which is snapped into connection with the snap-fit plate through the snap-fit notch.
[0010] Preferably, both the male and female housings have a limiting seat on the outer wall near the connecting seat, and the outer surface of the connecting seat has a limiting groove, with the limiting seat inserted into the limiting groove.
[0011] Preferably, a buckle seat is provided on one side of the limiting seat, and a buckle groove is provided on one side of the limiting groove, and the buckle groove is engaged with the buckle seat for buckling and fixing.
[0012] Preferably, a sealing seat is provided inside the other end of both the male head housing and the female head housing, and a sliding seat is provided on the lower surface of the male head housing.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model sets an elastic inner ring inside the female connector, moves the sealing ring along the connecting slot, and fits on the outside of the elastic inner ring. Relying on the elasticity of the outer side of the elastic inner ring, the sealing ring is tightened to prevent slippage and improve connection stability. When the male connector shell and the female connector shell are connected, one end of the male connector shell is inserted into the connecting slot to contact and squeeze the sealing ring, thereby improving the sealing performance of the connection and the waterproof effect. Moreover, the seal is located inside the male connector shell and the female connector shell, rather than being connected by a buckle on the outside, which improves safety, makes it less prone to damage, and extends service life. It solves the problem that most existing long-bodied male and female connectors waterproof by adding a buckle structure on the outside, which is easy to be bumped and damaged, has low safety, and is also prone to aging when exposed to the outside, resulting in poor waterproof effect.
[0015] (2) By setting a slide on the lower surface of the male head housing, the long-body male and female heads can be connected to the vehicle body through the slide, instead of simply fixing with screws. The slide will play a role in limiting the connection and preventing it from falling, thus improving the flexibility and stability of fixing. Attached Figure Description
