Abstract

The utility model relates to an improved structure of an earphone socket. Mainly, a circuit board is provided with a combining groove. When earphones and an earphone socket are combined, two terminal sheets are arranged on the socket with the mode of coverage. Extending parts on both sides of the terminal sheets are contacted with a circuit on the circuit board, and can be fixedly combined by solder, so the combined thickness is reduced with less integral volume. In addition, the coverage and contact between the two terminal sheets can provide variable conductive mode to increase the function of sound effect.

Description

The structure-improved of earphone socket

Technical field

The utility model relates to electric type, particularly a kind of structure-improved of earphone socket.

Background technology

The common earphone socket and the compound mode of circuit board are shown in accompanying drawing 1 and accompanying drawing 2, its structure is the terminal 11 that is provided with protrusion in a side of earphone socket 1, with respect to the perforate on the circuit board 2 21, can plug together in perforate 21 for terminal 11, side open in addition from circuit board 2, mat scolding tin is connected with circuit 22 on it then, promptly reach the purpose of conduction, but behind this kind textural association, its thickness comprises the thickness of circuit board 2 and soldering-tin layer and earphone socket 1 addition, occupy bigger volume, can not obtain perfect effective utilization, need be improved.

The utility model content

According to the purpose of this utility model, shortcoming at above-mentioned common earphone socket existence, a kind of structure-improved of earphone socket is provided, mainly on circuit board, be provided with an engagement groove, provide the earphone socket combination therebetween, the two-terminal sheet is with coverage mode, be located on the socket, the both sides extension of terminal plate circuit proper and on the circuit board contacts, but mat scolding tin secure bond, so can reduce its combination thickness, littler overall volume is provided, by the covering contact of two groups of terminal plates, provide the conduction mode of changeability in addition, promote the audio function.

1 is that earphone socket, 11 is plug for auxiliary body, 4 for engagement groove, 3 for circuit, 23 for perforate, 22 for circuit board, 21 for extension, 2 for terminal plate, 13,13 ' for terminal, 12,12 '.

Embodiment

Shown in accompanying drawing 3 and accompanying drawing 4, the utility model includes an earphone socket 1 and a circuit board 2, wherein a side of circuit board 2 is provided with an engagement groove 23, can be therebetween for earphone socket 1 engaging, array terminal plate 12,12 ' then covers in the top of socket 1, and its side is respectively equipped with extension 13,13 ', can be contacted with on the corresponding circuit 22 of circuit board 2, and can utilize scolding tin to make extension 13,13 ' is fixed on the circuit board 2, be to be able to combine with the firm conduction of circuit board 2 with earphone socket 1, the thickness of this structural entity is equivalent to the thickness of earphone base, more common earphone base structure, promptly reduced the thickness of circuit board and soldering-tin layer, reached reduction thickness, reduced it and take up space and convenient durable effect.

Shown in accompanying drawing 5 and accompanying drawing 6, when combination earphone socket 1 and circuit board 2, commanding apparatus for ease of automation, can be provided with an auxiliary body 3 in addition, its cover is closed in the outside of earphone socket 1, after can being positioned at the engagement groove 23 of circuit board 2 for easy this member of absorption, the unloading body 3 again, and operation sequence easily can be provided.

Shown in accompanying drawing 7 and accompanying drawing 3, when headset plug 4 does not insert earphone socket 1, terminal plate 12,12 ' is and overlaps conducting mutually, to form inner looping, so do not influence the path of circuital current, after plug 4 inserts earphone base 1, shown in accompanying drawing 10 and accompanying drawing 9, terminal plate 12 can be backed down and do not contact with terminal plate 12 ', and only contact conducting with plug 4, be the quality that can promote radio reception, promote effect.

Claims

1, a kind of structure-improved of earphone socket, include an earphone socket and a circuit board, it is characterized in that: the side at circuit board is provided with an engagement groove, can be therebetween for the earphone base engaging, the relative terminal plate of array then covers the top in socket, and its side is respectively equipped with extension, is can be contacted with on the corresponding circuit of circuit board, and available scolding tin is fixed on the circuit board extension, forms firm conduction and connects.

2, according to the structure-improved of the described a kind of earphone socket of claim 1, it is characterized in that: said relative two-terminal sheet is to be to overlap conducting mutually when plug does not insert earphone socket.
