Abstract

The invention relates to a protection bracket for a headset socket. The protection bracket is a surface-mounted protection bracket for the headset socket on a portable electronic terminal product, such as a mobile phone, a flat panel computer, an MP3, an MP4, and a personal stereo. The protection bracket is shaped into a square shell matched with the appearance of the headset socket; an opening part is formed on the upper surface of the rear part of the protection bracket; insertion pins are respectively arranged near four corners of the protection bracket and embedded into a printed circuit board; and the headset socket is fixed on the printed circuit through a surface mounting technology (SMT) soldering mode of a soldering furnace. The protection bracket for the headset socket is easy to assemble and cannot be damaged under strong impact, such as falling, so that the reliability of the headset socket is improved, an aim of protecting the headset socket is fulfilled, and the impact resistance is improved obviously.

Description

The earphone socket protective cradle

Technical field

The present invention relates to a kind of earphone socket protective cradle, be specifically related to the SMD protective cradle that a kind of earphone socket that is used on the portable type electronic products such as mobile phone, panel computer, MP3, MP4, walkman is used.

Background technology

In portable type electronic products such as mobile phone, panel computer, MP3, MP4, walkman; The use earphone is listened to the music; The earphone socket frequency of utilization is higher, also has some failtestss, for example intense impact such as bare machine drop test, cylinder drop test, slotting earphone drop test; The leg solder crack often occurs, fall phenomenon such as pad, cause ear-phone function to lose efficacy.

For example, patent documentation CN1805610A discloses a kind of slip-off preventing bonding-free earphone protective cover, and cover body is interconnective interior snap ring and the outer cover that soft material constitutes, and interior snap ring is provided with the stuck point that prevents that outer cover from coming off.

In addition, patent documentation CN2738431Y discloses a kind of improvement of headset plug fixed structure, the improvement of headset plug fixed structure, and it comprises: plug, one of which end vertically convex with at least one locking plate and axially have a metal joint; And holder; It has a signal jack and can supply this plug to plant; And have at least one lockhole corresponding to this locking plate place, and have at least one annular guide channel, so that this locking plate can slide with this plug that locks along this annular guide channel after inserting this lockhole in the side of this lockhole.

But; Only relate to be arranged at the fixedly protection structure on the headset plug in these patent documentations, do not relate to the socket that the terminal supplies headset plug to insert, and earphone socket is still than phenomenon such as be easier to weldering to occur falling, come off; For this reason, require to propose a kind of more durable earphone socket structure.

Summary of the invention

The present invention provides a kind of earphone socket protective cradle in view of this problem, it is characterized in that; It is the SMD protective cradle that is used for the earphone socket on the such portable electronic terminal product of mobile phone, panel computer, MP3, MP4, walkman; Said protective cradle forms the square casing that is complementary with said earphone socket profile, and its rear upper surface forms open oral area, is respectively equipped with pin near its four bights; Said pin is embedded on the printed circuit board (PCB); SMT (Surface mounting technology, surface adhering technology) soldering through pin is crossed brazier is fixed on said earphone socket on the printed circuit board (PCB).

The present invention is preferably, and said pin is provided with four, and two pins are arranged on the outside in two bights of front end of said protective cradle, and two other pin is arranged on the inboard in two bights, rear end of said protective cradle.

Utilize earphone socket protective cradle according to the invention, can protect earphone socket not to be damaged being fallen etc. under the intense impact better, improved the reliability of earphone socket.

Earphone socket protective cradle assembling involved in the present invention is simple, reliable, has reached the purpose of protection earphone socket, and its impact resistance is obviously promoted.

Embodiment

Below, in conjunction with accompanying drawing and most preferred embodiment just the technical scheme of earphone socket protective cradle of the present invention be further described.

Consult the most preferred embodiment of the earphone socket protective cradle of Fig. 1～shown in Figure 6; The said earphone socket protective cradle 1 of present embodiment is a kind of SMD earphone socket protective cradle; Said earphone socket 2 is used for portable electronic terminal products such as mobile phone, panel computer, MP3, MP4, walkman, and protective cradle 1 forms the square casing that the profile with said earphone socket 2 is complementary, and the rear upper surface of protective cradle 1 forms open oral area 4; Its four bights are formed with pin 6; Said pin 6 can be provided with a plurality of, and in the present embodiment, pin 6 is provided with four; Two outsides that are arranged on two bights of front end of said protective cradle 1, two other is arranged on the inboard in two bights, rear end of said protective cradle 1.

Said pin 6 is embedded on the printed circuit board (PCB) 3, and said pin 6 is crossed brazier carry out the SMT soldering, said earphone socket is securely fixed on the printed circuit board (PCB) 3.

Above-described only is principle of the present invention and most preferred embodiment.Should be pointed out that to those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, also should be regarded as belonging to protection scope of the present invention.
