Abstract
The utility model relates to a telephone socket connector, particularly a microphone line twisting-free device which can avoid the disorder twisting of a telephone receiver. The utility model is composed of a four-core plug and a four-core socket, wherein, a round base is arranged at the lower part of the four-core plug, the bottom surface of the base is provided with a circuit board, two concentric circular copper sheets are respectively arranged on the circuit board, and the copper sheets are connected with a four-core copper sheet by conducting wires. The four-core socket is provided with a groove which is matched with the round base, the bottom of the groove is provided with two contact pieces of an electric conduction spring, and the contact pieces of the electric conduction spring are connected with the four cores in the socket by conducting wires. The positions of the contact pieces of the electric conduction spring just contact the two circular copper sheets for conduction. The utility model has the advantage that the utility model can be use after inserted.
Description
The utility model relates to a kind of phone connector.
The connecting line of existing telephone receiver and main frame is generally adopted international standards patches structure, and the advantage of this structure is to use conveniently.Random phenomenon together can appear twisting in telephone wire inevitably, thereby plug is come off but in use.
The purpose of this utility model provides a kind of random microphone cord of receiver words line strand of avoiding and exempts to twist device.
The technical solution of the utility model is: be made of four-core plug, four-core socket, it is characterized in that: be provided with a round base below the described four-core plug, this base bottom surface is provided with a circuit board, circuit board is provided with two annular concentric copper sheets, and annular copper sheet links to each other by lead with four-core copper sheet on the described four-core plug.Described four-core socket is provided with the groove that the round base with the four-core plug matches, and is provided with at least two power spring contacts in the bottom of this groove, and links to each other in twos with four-core in the socket by lead.The position of described power spring contact contacts conduction with two annular copper sheets just.
The utility model has the advantages that: simple in structure, need not change telephone set, can use after the insertion.
Now in conjunction with the accompanying drawings and embodiments the utility model is described as follows:
Accompanying drawing: be structural representation of the present utility model.
Four-core plug 5, four-core socket 2 are the international standard part among the figure, and invention key of the present utility model is its both connection.Described four-core plug 5 has a round base 6, and these pedestal 6 bottom surfaces are provided with a circuit board 7, and circuit board 7 is provided with two annular concentric copper sheets 8, and each annular copper sheet 8 is connected with relevant chip 4.Described four-core socket 2 is provided with the groove 10 that the round base 6 with four-core plug 5 matches, and is provided with four power spring contacts 9 (only drawing among the figure two) in the bottom of this groove 10.This power spring contact 9 links to each other in twos by four chips 1 in lead and the four-core socket 2.The position of described power spring contact 9 contacts conduction with two annular copper sheets 8 just.Microphone cord of the present utility model exempts to twist device in use, four-core plug 5 is inserted in the four-core socket of telephone receiver, and former receiver words line is inserted in the four-core socket 2.Because the round base 6 of four-core plug 5 can rotate arbitrarily by 360 degree in the groove 10 of four-core socket 2, so can avoid receiver words line strand disorderly.
