Abstract

A plug-in socket is provided, the structure of the plug-in socket is provided with a first inserting terminal, a second inserting terminal, a third inserting terminal and a fourth inserting terminal, wherein, the first and the second inserting terminals are respectively connected with the output end of an amplifier, and the third and fourth inserting terminals are respectively connected with a loudspeaker; when the plugs of the earphones are not inserted, the first, second, third and fourth inserting terminals are in mutual contact states, when the earphones are inserted, the first and second inserting terminals are pushed by the earphones and separated from the third and fourth inserting terminals, which results in that the amplifier which is originally connected with the loudspeaker is automatically switched to the connecting state with the earphones, and when the earphones are inserted, the earphones are contacted with the amplifier closely because the first and the second inserting terminals are of arc-curve shapes.

Description

Plug socket

Technical field

With the insertion of earphone whether the utility model relates to a kind of plug socket, is a kind of plug socket volume-diminished that makes, and can be, the structure of automatic switchover connection status.

Background technology

Consult shown in Figure 1, general traditional plug socket, it is provided with a housing 100, these housing 100 1 terminations are provided with an outstanding plug 110, this joint 110 is provided with the jack that extends outside housing 100, and be provided with inserting terminal 120 in this housing 100, this inserting terminal 120 is provided with the protruding link 121 that is exposed at outside the framework 100, wherein the link 121 of an inserting terminal 120 is to be connected with ground wire, the link of two remaining inserting terminals 120 then is connected with the expander (not shown), when making earphone insert, can touch with the inserting terminal 120 in housing 100, and keep conducting state with expander by jack.Its major defect is: because inserting terminal 120 is to be flat, so can't fully closely abut in plug, produce the situation of loose contact; In addition, because of this connection-peg is directly to be connected with expander, so, when not wanting to use earphone, must expander be connected with loudspeaker as the user, can't be with the insertion or the extraction of earphone, and automatic switchover expander connection status is very inconvenient in the use.

Summary of the invention

For improving above-mentioned various shortcomings, the inventor is to be engaged in such manufacturing industry experience for many years, and through the permanent research and experiment of making great efforts, development and Design goes out plug socket of the present utility model finally.

Main purpose of the present utility model provides a kind of plug socket, this plug socket is inserted with most the inserting terminals at diverse location, wherein, first and second inserting terminal is connected with the expander output respectively, third and fourth inserting terminal is connected with loudspeaker respectively, and when headset plug does not insert, first, second, third and fourth inserting terminal is to be in the state that touches mutually, and when earphone inserts, first and second inserting terminal can be squeezed by earphone and hold, separate with third and fourth inserting terminal, reach the expander that script is connected with loudspeaker, automatically switch on the earphone.

Another purpose of the present utility model provides a kind of plug socket, the end of its first and second inserting terminal in plug socket is to be arc-curved shape, when order is used, the elastic reaction that inserting terminal can be produced by an end that is arc-curved shape, more closely abut in the earphone that inserts wherein, reach the purpose of the situation generation that does not have loose contact.

The purpose of this utility model is achieved in that a kind of plug socket, it is characterized in that: it includes more than one inserting terminal and is plugged in the housing, first and second inserting terminal is connected with the expander output respectively, third and fourth inserting terminal is connected with loudspeaker respectively, and this first, second, third and fourth inserting terminal headset plug is to be in the state that touches mutually; This first and second inserting terminal is squeezed by earphone and opens, and separates with third and fourth inserting terminal, makes the expander that originally is connected with loudspeaker, automatically switches to earphone to be connected.

The end of this first and second inserting terminal in housing is to be arc-curved shape, and the elastic reaction that this first and second inserting terminal is produced by an end that is arc-curved shape closely abuts in the earphone that inserts wherein.

Describe in detail below in conjunction with the preferred embodiment conjunction with figs..
