Abstract

The utility model relates to a rotary socket for telephone used on the connecting wire between the telephone and the microphone. The rotary socket for telephone comprises a shell. The incoming conducting wires from the both ends of the shell contact and are connected with each other via a rotary joint in the form of the electric brush in the shell. One end of the rotary joint is connected with the special standard plug of the telephone, and the other end of the rotary joint is rotatablely connected with a special-purpose faucet of the telephone. This rotary socket is adopted on the telephone, when the telephone wire winds, the telephone or the microphone is needed to be turned, only the shell of this rotary socket is needed to be turned, the winding of the telephone wire can be released, and this rotary socket for telephone is easy to be used.

Description

Rotary socket for telephone

The utility model relates to the socket of using on a kind of telephone set, and particularly a kind of telephone set that is used for is connected telephone set rotary socket on the lead with microphone.

In the prior art, the lead of telephone set is to be connected with standard plug on the external wire by the standard socket on the telephone set, and is easy to connect.But telephone set or microphone have rotation slightly, and telephone wire will twine together, brings inconvenience to the user.

The purpose of this utility model is to provide a kind of telephone set rotary socket, occurs twining a time-out at telephone wire, rotates the standard plug on the lead a little, can remove the winding of telephone wire, and is extremely easy to use.

In order to achieve the above object, the utility model adopts following technical proposals: the utility model is the same with prior art to include a housing.Be characterized in: the lead of introducing from the housing two ends connects by an electric brush type swivel joint contact in the housing.In use, when telephone wire occurring and being intertwined, only need to rotate swivel joint or housing, can remove the wrapping phenomena of telephone wire.

One end of above-mentioned swivel joint can a fixedly connected telephone set application specific standard plug, the telephone set application specific standard socket and the other end can be rotatably connected.Like this, can be with the standard socket on the standard plug grafting telephone set on the utility model, and the standard socket on the utility model can be pegged graft with the standard plug on the telephone wire.When the telephone wire winding occurring, rotate housing of the present utility model, can remove the winding of telephone wire.

For the ease of making assembling, above-mentioned swivel joint can be front and back two semi-involution structures.Four leads introducing from left end lead to winding one circle in four grooves of swivel joint outer wall respectively in the swivel joint center cavity; Four leads that four leads introducing from right-hand member are introduced with left end in four grooves of swivel joint outer wall respectively suppress contact and are connected.Four leads that left end is introduced are connected with four leads in the standard plug respectively; Four interior elasticity acupuncture needles of four leads that right-hand member is introduced and standard socket are connected.

In order to make compact conformation, the structure of standard socket of the present utility model can be designed as: at acupuncture needle cell body that is rotatably connected with swivel joint of right-end openings internal fixation grafting of housing, acupuncture needle cell body inner chamber one side is settled four elasticity acupuncture needles that are connected with the left end lead-in conductor.In the actual production, can be right-hand member lead-in conductor and acupuncture needle with whole elastic metal wire brake forming; And the lead in left end lead-in conductor and the standard plug is the lead of whole continuity.Housing and swivel joint can be used injection molding.

The utility model has conspicuous advantage compared with prior art: adopt the utility model on the telephone set, when the telephone wire winding occurring, need not to rotate telephone set or microphone, only need to rotate housing of the present utility model, can remove the winding of telephone wire, easy to use.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1 is the structural representation (being the cutaway view at A-A place among Fig. 2) of an embodiment of the utility model.

Fig. 2 is the top view of Fig. 1.

Fig. 3 is the left view of Fig. 1.

An optimum implementation of the present utility model is: referring to Fig. 1, Fig. 2 and Fig. 3, this telephone set rotary socket includes a housing 6, the swivel joint 4 of one two semi-involution structure is housed in the housing 6, and swivel joint 4 stretches out from housing 6 left ends and fixedlys connected with a telephone set application specific standard plug 2.Four leads in the standard plug 2 are whole lead with the lead of introducing from housing 6 left ends 3, they lead to respectively in swivel joint 4 center cavities in four grooves of swivel joint 4 outer walls twines a circle, and the left end of this lead is connected with metal insert 1 on the standard plug 2.At acupuncture needle cell body 8 that is rotatably connected with swivel joint 4 of right-end openings internal fixation grafting of housing 6, acupuncture needle cell body 8 inner chambers one side is settled four elasticity acupuncture needles 7 that are connected with right-hand member lead-in conductor 5, constitutes standard socket 9.Four leads 3 that four leads 5 that right-hand member is introduced are introduced with left end in four grooves of swivel joint 4 outer walls respectively suppress contact and are connected.The elastic metal wire brake forming that right-hand member lead-in conductor 5 and acupuncture needle 7 usefulness are whole.Standard plug 2, housing 6, swivel joint 4 and acupuncture needle cell body 8 are by the transparent plastic injection mo(u)lding.
