Problems solved by technology

Considering that the earphones of the mobile phone will not be used for a long time, the exposure of the groove of the earphone plug will accumulate dust, which will affect the performance of the mobile phone. Therefore, there are currently dust-proof and waterproof mobile phones that can be used as decorations on the market. plug, but the traditional mobile phone dust-proof plug is more focused on the appearance design of the dust-proof plug. In the connection structure, the decorative part is directly bonded to the plastic plug part with glue, which leads to the difference between the decorative part and the plastic plug. The contact surface is small and the glue bonding area is small, which makes the structural design unreliable. Many plugs will separate from the decorative part and the dustproof part, that is, the plastic plug after a short period of use, and even the plastic plug will be stuck in the headphone jack alone and cannot be pulled out. Out of the situation

Embodiment Construction

[0016] refer to Figure 1~Figure 3 , a mobile phone dust-proof plug of the present invention, which includes a decoration 1 and a rubber sleeve 2, the rubber sleeve 2 can be made of POM plastic, the decoration 1 is fixed with an alloy pin 3, and the alloy pin 3 is made of an alloy material The length of the alloy pin 3 is generally 6-10 mm, and the side wall of the alloy pin 3 is provided with a groove 31. The groove 31 is preferably 2.0-2.4 mm away from the bottom end of the alloy pin 3. The groove 31 can preferably be 1 mm long, the rubber sleeve 2 is provided with a slot 21 that is compatible with the alloy pin 3, that is, the cross-sectional diameter of the alloy pin 3 can be equal to the diameter of the slot 21, according to the size of the actual mobile phone earphone jack , the cross-sectional diameter of the alloy pin 3 can be selected as 1.15 mm. At this time, the diameter of the slot 21 is also 1.15 mm. After the alloy pin 3 is inserted into the slot 21, it is glued ...

Abstract

The invention relates to a dustproof plug for a mobile phone. The dustproof plug consists of a decoration and a rubber sleeve, wherein the decoration is fixedly provided with an alloy contact pin, a groove is arranged on the side wall of the alloy contact pin, the rubber sleeve is provided with a slot adaptive to the alloy contact pin which is inserted in the slot and then is fixed by adhesion of glue. The dustproof plug can enable solidified glue to form a clamping jaw in the groove for clamping the alloy contact pin, also obviously enlarges the contact area between the decoration and the rubber sleeve compared with the connection structure in the prior art, increases the bonding surface between the decoration and the rubber sleeve, enables the bonding effect to be better, ensures the connection reliability between the decoration and the rubber sleeve, prevents the decoration from being separated from the rubber sleeve in use process, and eliminates the phenomenon that the corresponding rubber sleeve cannot be pulled out after independently sinking in the jack of a mobile phone earphone; and the dustproof plug has very high reliability and safety.

Description

technical field [0001] The invention relates to a dust-proof plug for a mobile phone, in particular to a dust-proof plug for a mobile phone that is applied to the slot of an earphone outside the mobile phone. Background technique [0002] The mobile phone is one of the most important symbols of modern society, and it is quite popular now. Everyone in the city will have at least one mobile phone. Therefore, the personalization of mobile phones has gradually become the pursuit of urbanites, and various mobile phone accessories have also come into play. However, mobile phone dustproof accessories are one of them. Considering that the earphones of the mobile phone will not be used for a long time, the exposure of the groove of the earphone plug will accumulate dust, which will affect the performance of the mobile phone. Therefore, there are currently dust-proof and waterproof mobile phones that can be used as decorations on the market. plug, but the traditional mobile phone dus...
