Description

Headphone socket protection bracket

technical field

The invention relates to a protective bracket for an earphone socket, in particular to a patch-type protective bracket for the earphone socket on portable electronic products such as mobile phones, tablet computers, MP3, MP4, and walkmans.

Background technique

In portable electronic products such as mobile phones, tablet computers, MP3, MP4, and Walkmans, earphones are used to listen to music, and the earphone socket is used frequently. There are also some reliability experiments, such as bare metal drop test, drum drop test, and earphone drop test. Such as strong impact, there are often phenomena such as tin cracking of solder feet and dropping of pads, which will cause the function of the earphone to fail.

For example, patent document CN1805610A discloses an anti-falling-off and non-adhesive earphone protective cover. The cover body is an interconnected inner snap ring and outer cover made of soft materials, and the inner snap ring is provided with snap points to prevent the outer cover from falling off.

In addition, the patent document CN2738431Y discloses an improvement of the fixing structure of the earphone plug. The improvement of the fixing structure of the earphone plug includes: a plug, one end of which is protruded longitudinally with at least one locking piece and has a metal joint in the axial direction; and a fixing seat , which has a signal jack for the plug to be inserted, and has at least one lock hole corresponding to the lock piece, and has at least one annular guide groove on the side of the lock hole, so that the lock piece can be inserted into the lock hole Then slide along the annular guide groove to lock the plug.

However, these patent documents only refer to the fixed protective structure arranged on the earphone plug, and do not involve the terminal socket for the earphone plug to be inserted into, and the earphone socket is still relatively prone to soldering, falling off, etc. Therefore, it is required to propose a More durable headphone socket structure.

Contents of the invention

In view of this problem, the present invention provides a protective bracket for earphone jacks, which is characterized in that it is a patch-type protective bracket for earphone jacks on portable electronic terminal products such as mobile phones, tablet computers, MP3, MP4, and Walkmans. , the protective bracket is formed as a square shell matching the shape of the earphone socket, the upper surface of the rear part is formed as an open mouth, and pins are respectively provided near the four corners, and the pins are embedded in On the printed circuit board, the earphone socket is fixed on the printed circuit board through SMT (Surface mounting technology, surface mount technology) soldering of the pins through the soldering furnace.

Preferably in the present invention, there are four pins, two pins are set on the outer sides of the two front corners of the protective bracket, and the other two pins are set on the inner sides of the rear two corners of the protective bracket .

The protection bracket for the earphone jack of the present invention can better protect the earphone jack from being damaged under strong impacts such as falling, thereby improving the reliability of the earphone jack.

The protection bracket for the earphone jack involved in the invention is simple and reliable to assemble, achieves the purpose of protecting the earphone jack, and significantly improves the impact resistance.

Detailed ways

Hereinafter, the technical solution of the earphone socket protection bracket of the present invention will be further described in conjunction with the accompanying drawings and the preferred embodiments.

Referring to the best embodiment of the earphone socket protection bracket shown in Figures 1 to 6, the earphone socket protection bracket 1 of this embodiment is a patch type earphone socket protection bracket, and the earphone socket 2 is used for mobile phones, On portable electronic terminal products such as tablet computers, MP3, MP4, Walkman, etc., the protective bracket 1 is formed as a square shell matching the shape of the earphone socket 2, and the rear upper surface of the protective bracket 1 is formed as an open mouth. 4. Pins 6 are formed at the four corners, and multiple pins 6 can be provided. In this embodiment, there are four pins 6, two of which are arranged at the front two corners of the protective bracket 1 The other two are arranged on the inner side of the two corners of the rear end of the protective bracket 1 .

The pins 6 are embedded on the printed circuit board 3 , and the pins 6 are soldered by SMT through a soldering furnace, so that the earphone socket is firmly fixed on the printed circuit board 3 .

What has been described above is only the principles and preferred embodiments of the invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the principle of the present invention, which should also be regarded as belonging to the protection scope of the present invention.
