Specifically can be as shown in Fig. 1,3 and 5：A part for first grounding pin (31A, 31B) and the inwall of jack 1 are pasted
Close, another part of the first grounding pin (31A, 31B) extends toward hollow part, until the first grounding pin (31A, 31B) extension
To outside jack 1, because the first grounding pin (31A, 31B) extends toward conduction region 211, so reducing the first grounding pin
(31A, 31B) and conduction region 211 spacing, electrostatic will be easier to be transferred on the first grounding pin (31A, 31B), it is to avoid electrostatic
It is transferred on conduction region 211, to prevent from puncturing terminal, influences the normal work of terminal.
It is preferred that, the part that first grounding pin (31A, 31B) is placed in outside the jack 1 and the conduction region 211
Spacing be 0.9~1.2mm.
I.e. the utility model can use implementation below：
1st, as shown in figure 5, the spacing of the first grounding pin 31B parts being placed in outside jack 1 and conduction region 211 is set to
0.9mm, using the direction shown in Fig. 5 as reference, now the first grounding pin 31B can pass through past top extension and past horizontal direction
The mode of extension is close to conduction region 211；
2nd, as shown in figs. 1 and 3, the first grounding pin 31A parts being placed in outside jack 1 and the spacing of conduction region 211 are set
1.2mm is set to, using the direction shown in Fig. 1 and 3 as reference, now the first grounding pin 31A can be by way of toward top extension
Close to conduction region 211.
Obviously, the part and the spacing of conduction region 211 that the first grounding pin (31A, 31B) is placed in outside jack 1 are smaller, electrostatic
The difficulty for reaching conduction region 211 is just higher, so the first grounding pin 31B is placed between the part outside jack 1 and conduction region 211
During away from for 0.9mm, its anti-static ability is more preferably.
It is preferred that, the ground connection conducting strip 3 at least two, each described first grounding pin (31A, 31B) is placed in institute
State the part outside jack 1 toward the conduction region 211 to extend, and be separated from each other with the conduction region 211.
First grounding pin (31A, 31B) is used to draw electrostatic, it is to avoid electrostatic reaches conduction region 211, so increase ground connection
After conducting strip 3, electrostatic absorption can be carried out by multiple first grounding pins (31A, 31B), so as to further increase ear
The anti-static ability of machine jack base.
It is preferred that, as shown in Fig. 3 to 5, the ground connection conducting strip 3 is two, two first grounding pins (31A,
Portion 31B) being placed in outside the jack 1 is respectively arranged on the both sides of the conduction region 211.
An embodiment i.e. of the present utility model can be as shown in Fig. 3 to 5：Two the first grounding pins (31A, 31B)
A part fitted with the inwall of jack 1, another part of two the first grounding pins (31A, 31B) extends toward hollow part, directly
Extended to the first grounding pin (31A, 31B) outside jack 1, using the direction shown in Fig. 3 to 5 as reference, now two first connect
Ground pin (31A, 31B) is arranged in the left and right sides of conduction region 211, electrostatic can be absorbed from wide range, it is to avoid
Electrostatic is transferred on conduction region 211, further increases anti-static ability.
Certainly, the first grounding pin (31A, 31B) is arranged in the left side and downside or right side and downside of conduction region 211 also
Can.

Cause the standby more preferably anti-static ability of earphone jack seat tool, preferably use Anti-static paint as insulating coating.
Wherein, the coating method of Anti-static paint is varied, and for example microphone conducting strip (2A, 2B) need to can be carried out electrically
The position of connection is carried out blocking covering, and then microphone conducting strip (2A, 2B) is immersed in Anti-static paint, treats that Anti-static paint is cold
But after solidifying, removal just may be used to blocking for microphone conducting strip (2A, 2B).
It is preferred that, as illustrated in fig. 1 and 2, the microphone conducting strip 2A is additionally provided with the 3rd microphone pin 23, the described 3rd
Microphone pin 23 is placed in outside the jack 1.
Specifically, second microphone pin 22 is arranged by the form for meeting earphone international standard, the 3rd microphone pin 23
Form by earphone Chinese Industrial Standards (CIS) is met is arranged, so setting second microphone pin 22 and the 3rd microphone pin 23 simultaneously
Afterwards, the earphone jack seat described in present embodiment can be applicable two kinds of standards simultaneously, expand earphone described in present embodiment of knowing clearly
The scope of application of jack base.
Ear on terminal described in the utility model embodiment, including casing and above-mentioned earphone jack seat, the casing
Machine hole, the earpiece holes are communicated with the casing internal, and the earphone jack seat is in the casing, the earphone jack seat
Jack 1 and the earpiece holes it is positioned opposite.
Terminal can be the equipment such as mobile phone, tablet personal computer, laptop computer, MP3, MP4, described in the above-mentioned embodiment of application
Earphone jack seat after, electrostatic will be difficult to through earphone jack seat punch-through is caused to terminal, substantially increase the stabilization of terminal
Property.
Earphone extended line described in the utility model embodiment, including socket, extended line, plug and above-mentioned earphone are inserted
Hole seat, the earphone jack seat is in the socket, and the earphone jack seat is electrical by the extended line and the plug
Conducting.
Because the line length of earphone is limited, it is difficult to be applied to all application scenarios, in order to solve such case, just may be used
Using earphone extended line, to increase the signal transmission distance of earphone；And using above-mentioned earphone jack seat on earphone extended line,
The anti-static ability of earphone extended line can be improved, and prevents electrostatic from causing to puncture to terminal by earphone extended line.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and moistened
