In one embodiment of the present utility model, as shown in fig. 1, there is provided an earphone connection structure including a male connector 100 and a female connector 200. The male connector 100 is provided with a plurality of catching parts 300. The female connector 200 is provided with a fixing groove 210. When the male connector 100 is inserted into the female connector 200, the holding portion 300 is held by the inner wall of the fixing groove 210. The male connector 100 and the fixing groove 210 are fixed by glue bonding.

The male connector 100 and the female connector 200 are respectively disposed on two components to be assembled and connected. During assembly connection, the clamping part 300 is inserted into the fixing groove 210, so that rapid assembly connection is realized, and the male connector 100 and the female connector 200 are automatically buckled and are not easy to loose because the clamping part 300 and the inner wall of the fixing groove 210 are clamped with each other.

In other embodiments of the present utility model, the male connector 100 and the fixing groove 210 are fixed by glue bonding. When glue is injected, the glue fills the glue storage groove 121 and the gap between the male connector 100 and the female connector 200.

The utility model combines the advantages of the buckle connection and the glue adhesion, so that the earphone is simple and quick to assemble and has better connection stability. Meanwhile, the strong adhesiveness of the glue can strengthen the stability of the male connector 100 and the female connector 200, and the male connector 100 and the female connector 200 are not easily separated even if abrasion occurs. In addition, the glue poured into the male connector 100 and the female connector 200 may form a solid bonding portion after solidification to fill the assembly gap between the male connector 100 and the female connector 200, so that the male connector 100 and the female connector 200 are in a sealed state, and external dust is not easy to enter the assembly gap between the male connector 100 and the female connector 200.

In other embodiments of the present utility model, as shown in fig. 1, 2 and 4, the male connector 100 includes a base 110 and a connecting post 120. One end of the connection post 120 is connected to the base 110. The catch 300 includes a plurality of arcuate bosses 310. The arc-shaped bosses 310 are linearly arranged at equal intervals on the side surfaces of the connection post 120, and when the connection post 120 is inserted into the fixing groove 210, the arc-shaped bosses 310 abut against the inner wall of the fixing groove 210, thereby fixing the connection post 120 in the fixing groove 210. And since the arc-shaped bosses 310 are linearly arranged at equal intervals, concave grooves are necessarily formed between the arc-shaped bosses 310. These grooves increase the roughness of the side surface of the connection post 120, thereby increasing the friction between the connection post 120 and the fixing groove 210. As long as the connection post 120 is inserted into the fixing groove 210 to complete the engagement, the connection post 120 and the fixing groove 210 are not easily separated.

In other embodiments of the present utility model, the male connector 100 is made of an elastic material. Specifically, the male connector 100 is slightly larger than the size of the fixing groove 210. But since the male connector 100 is made of an elastic material, it has a certain elasticity itself. Therefore, when the fixing groove 210 is inserted, the clamping part 300 and the connection post 120 are elastically deformed to be inserted into the fixing groove 210. The compressed catching part 300 and the connection post 120 form an interference fit with the fixing groove 210, thereby more firmly connecting the male connector 100 and the female connector 200.

Specifically, in the present embodiment, the male connector 100 is made of rubber.

In other embodiments of the present utility model, as shown in fig. 2, one end of the arc-shaped boss 310 is bent toward the connecting post 120 to form a bent portion 311. Since the bending portion 311 is bent, the bending portion 311 is lower than the arc-shaped boss 310. When the arc-shaped boss 310 abuts against the inner wall of the fixing groove 210, a space is left between the bending portion 311 and the fixing groove 210, so that the connecting post 120 is easier to be inserted into the fixing groove 210 while sufficient interference between the arc-shaped boss 310 and the fixing groove 210 is ensured.

In other embodiments of the present utility model, as shown in fig. 2 and 4, the clamping portion 300 further includes a square boss 320. The square boss 320 is disposed on a side surface of the connection post 120 and connected to the bent portion 311. The fixing groove 210 includes a main notch 211 and a square notch 212. The square notch 212 communicates with the main notch 211. When the connection post 120 is inserted into the main slot 211, the square boss 320 is inserted into the square slot 212. The square notch 212 has an alignment function. When the connection post 120 is connected to the fixing groove 210, the square boss 320 needs to be aligned with the square notch 212, and the connection post 120 can be connected to the fixing groove 210. At the same time, the cooperation of the square boss 320 and the square notch 212 can prevent the connection post 120 from rotating in the fixing groove 210.

In other embodiments of the present utility model, as shown in fig. 2, the other end of the connecting post 120 is provided with a first pressing plate 122 and a second pressing plate 123. The outer side surface of one end of the first pressing plate 122 protrudes outwards to form a first hook 1221, and the first hook 1221 and the inner end of the square notch 212 are clamped with each other. An outer side surface of one end of the second pressing plate 123 protrudes outwards to form a second hook body 1231. The second hook 1231 is engaged with the inner end of the main slot 211, and the first hook 1221 is engaged with the inner end of the square slot 212, so that the connection stability between the connection post 120 and the fixing slot 210 is further enhanced, and the male connector 100 is not easy to withdraw from the fixing slot 210 even if being pulled outwards.

In other embodiments of the present utility model, as shown in fig. 2, the outer side surface of the first pressing plate 122 is connected to the outer surface of the square boss 320, i.e., the first pressing plate 122 is also protruded outward. After the first pressing plate 122 slides into the square notch 212, the square boss 320 slides in, so that the first pressing plate 122 protruding outwards has a guiding function, and the square boss 320 can enter the square notch 212 more easily.

In other embodiments of the present utility model, as shown in fig. 3, the outer surfaces of the first hook body 1221 and the second hook body 1231 are provided with chamfers 600. The first hook 1221 and the second hook 1231 are gradually enlarged from the front end to the rear end, facilitating the insertion of the front end of the connection post 120 into the fixing groove 210.

In other embodiments of the present utility model, as shown in fig. 2, a plurality of stoppers 111 are disposed at one end of the base 110 near the connecting post 120. When the connection post 120 is inserted into the fixing groove 210 and slid a certain distance to the inside thereof, the stopper 111 abuts against the notch of the fixing groove 210, thereby stopping the sliding of the connection post 120.

In other embodiments of the present utility model, as shown in fig. 1, the male connector 100 further comprises a protective sheath 130. The protective sleeve 130 covers the base 110. Specifically, the protective sheath 130 is made of rubber. The protective sleeve 130 not only protects the base 110, but also facilitates grasping by the manufacturer.

In other embodiments of the present utility model, as shown in fig. 1 and 4, the male connector 100 and the female connector 200 are respectively mounted on a component a and a component B to be connected, specifically, in this embodiment, the component a is an ear hook 400, and the component B is an ear shell 500. The inner frame of the ear hook 400 is inserted into the connection hole 112 of the base 110, thereby installing the male connector 100 on the ear hook 400. The female connector 200 is integrally formed with the ear shell 500, that is, the female connector 200 is disposed on the outer shell of the ear shell 500. Glue is then poured through the mutual engagement of the male connector 100 and the female connector 200, so as to finally achieve the tight assembly of the ear hook 400 and the ear shell 500 in the earphone.

It should be noted that, the earphone connection structure in the embodiment of the present utility model is not limited to be used for an earphone, but may be used for other electronic devices and mobile terminals, and is not particularly limited herein.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
