Description

Swivel joint

Technical field

The utility model relates to a kind of joint, especially relates to a kind of being applied between main station or microphone and microphone lead, microphone lead and main station or microphone can be rotated freely by 360 degree, with the swivel joint of avoiding the microphone lead to turn round volume, twine.

Background technology

Common telephone set, though can transmit by the signal and the telephone set of wireless mode with microphone, but the interference that is subjected to other electric wave owing to wireless signal is as easy as rolling off a log produces noise, thereby make its call tone quality not good, therefore, part telephone set or facsimile machine still adopt the telephone set of cable microphone to carry out the signal transmission, with the tonequality that guarantees to converse, and reduce the cost that telephone set is bought.

The shortcoming of wire transmission maximum is that the signal transmission range is subjected to the restriction of microphone conductor length, in addition, also can mention the often position of conversion hand microphone, back because of microphone, causes the microphone lead to turn round volume, twine, and causes the inconvenience in the use; Present prior art, be that a swivel joint is installed between microphone lead and main station or microphone, its swivel joint mainly is to be provided with a plug to be connected with microphone or main station, and be provided with a socket and be connected with the microphone lead, its plug can be connected with the socket forming circuit with the mandrel of the corresponding rotation of socket by one, make microphone lead and microphone or main station have the effect that 360 degree freely rotate, avoid the microphone lead to turn round volume, twine.

The plug of swivel joint similarly commonly used is connected the ways of contact of adopting single contact more with the circuit between the socket, when using, reality tends to influence the connection effect of circuit because of loose contact, this phenomenon can be more obvious when plug rotation corresponding with socket, thus, reduce the speech quality of wire transmission signal on the contrary, even influenced the operate as normal of telephone set.

Summary of the invention

The objective of the invention is to improve the shortcoming of prior art, provide a kind of 360 degree that make between microphone lead and main station or the microphone freely to rotate, avoid the microphone lead to turn round volume, twine, simultaneously, keep the good swivel joint of conversation signal work between main station or microphone and the microphone lead.

For achieving the above object, the present invention adopts following technical proposals: a kind of swivel joint, it is to be provided with two at each circuit place of plug one side by contact that ball constituted, make each circuit of plug be electrically connected on the related circuit of socket one side simultaneously by two contacts, and, when the rotation corresponding of microphone lead, still can keep good electrical connection effect, more can guarantee the operate as normal of telephone set with main station or microphone.

Described swivel joint is to be arranged with a mandrel and a socket respectively at the two ends of a sleeve, its mandrel is provided with end difference at the end towards socket, and be provided with spring along the mandrel radial arrangement at the corresponding site of each end difference, each spring is electrically connected on the terminal of a plug respectively, and the two ends of each spring all are provided with ball; Be arranged with conducting ring at described each end difference place, be not in contact with one another between the conducting ring, only contact with the ball of affiliated end difference; One side of described socket is the power spring with the corresponding quantity of conducting ring of being axially arranged with along mandrel, is not in contact with one another between the power spring, only contacts with pairing conducting ring.

Described swivel joint, it is a kind of structure that constitutes the socket and plug connection by mandrel, and each circuit of plug one side is electrically connected on the related circuit of socket one side by the ball of spring both sides, at the microphone lead during with the corresponding rotation of main station or microphone, still can keep good electrical connection effect, more can guarantee the operate as normal of telephone set.

The utility model can make between microphone lead and main station or the microphone 360 degree freely rotate, avoids the microphone lead to turn round volume, winding, and simultaneously, the signal work that can keep conversing between microphone and microphone lead and the main station is good.
