Abstract

A rotatable socket relates to a rotation technology for a plug at the tail end of an electrical line and is used for protecting the tail end line. The socket is composed of a line 1, a linear rotary body 2, a plug housing 3, a plug rotary body 4, a plug piece 5, a connecting line 6 and a fixed body 8. Under the condition that the line 1 or the plug 6 is stationary, the linear rotary body 2 can arbitrarily rotate around the line 1 as an axis. The design has the following advantages: A. The rotary design of the line 1 and the plug 6 can prevent the line 1 in use from being forced to rotate and damaged due to the rotation of the plug 6 for adapting to the position of the socket; B. compared with the mode that the regular line 1 is directly connected with the plug 6, when the line 1 is stretched or twisted, no direct force is applied to a conductor 11 in the line 1, so as to protect the key part of the line 1 and prolong the service life thereof. The design of the rotary plug is used not only in lines, but also in various data wires such as serial ports, parallel ports, USB, etc, and can also protect the lines.

Description

Rotatable plug and using method thereof

Technical field

The present invention relates to the technology of the terminal plug of a kind of electric appliance circuits, especially a kind of revolvable plug technology.

Background technology

Existing plug all is directly to be connected with circuit, and both cannot do relative rotation, when practicality, might make circuit cause certain damage because plug will be twisted (rotation) circuit for adapting to socket; Another kind of situation is, when the circuit tension or when being turned round, the position that circuit is connected with plug is easily caused and opened circuit.

Summary of the invention

The present invention is revolved body, jack shell, plug by circuit, line and is revolved body, plug blades and connecting line and form, and be with the difference of existing plug: plug directly is not connected with circuit.At first circuit revolves body with line and is connected, and plug revolves body and is connected with plug blades; Wherein, it is to contact with the relation that plug revolves body that line revolves body, can do relative rotation, and line revolves body can revolve the body inboard at plug, also can revolve external side at plug, and shown in Figure 1 is, and line revolves body revolves the body inboard at plug.So just can form path between the two as common line and plug.Jack shell plays the protection plug, and fixed body plays static line and revolves body.

When plug maintained static, circuit can be from rotating as axle; Equally, plug can be the axle rotation with the circuit when circuit maintains static also.

Embodiment

Rotatable plug revolves body (2), jack shell (3), plug by circuit (1), line and revolves body (4), plug blades (5), connecting line (7) and fixed body (8) and form.Suppose that circuit (1) includes two strip conductors (Fig. 1 as Figure of description shows), then other composition is pressed the two-wire design:

Plug body (5) does not contact and partly is embedded in jack shell (3). in, the other end of jack shell is tieline road (1) but the discontiguous curved line of two bodies is set in its end revolves body (2) not, and plug body (5) is revolved body (2) with line and is connected with connecting line (7) respectively; Conductor (11) in the circuit (1) revolves body with line respectively and is connected, and two lines revolve that body does not contact and be separately fixing by the fixed body (8) of injection moulding; Plug (6) directly is connected with conductor (11) with the non-plug body (5) that is connected of circuit (1), but: the plug of attachment plug body (5) revolves the line that body (4) is embedded in bonding conductor (11) contiguously and revolves body (2), line revolves body (2) and can be contiguously revolves body (4) with plug and do relative rotation and do not open circuit, in addition, line revolves body (2) and can revolve body (4) by the outsourcing plug.The advantage of the rotatable design of plug (6) is: during use, when A needs rotation to adapt to socket when plug (6), can keep circuit (1) not change, otherwise circuit (1) can be impaired because of distortion repeatedly; B can cause opening circuit of the two junction when plug (6) and circuit (1) are stretched (being typically headset plug), rotatable design increases the pulling force that can bear between the two widely, and the possibility that opens circuit between plug (6) and the circuit (1) is reduced widely.

When actual production is made, it shall yet further be noted that being connected between plug (6) and the circuit (1), promptly plug revolves body (4) and revolves being connected between the body (2) with line, and corresponding, suitable slip-off preventing design should be arranged.

Claims

1. rotatable plug revolves body (2), jack shell (3), plug by circuit (1), line and revolves body (4), plug blades (5), connecting line (7) and fixed body (8) and form, and it is characterized in that:

The end that A is connected with circuit (1) at plug (6) is provided with the conductive plug of arc and revolves body (4); The end that B circuit (1) is connected with plug (6) is provided with conductive line and revolves body (2); The C plug revolves body (4) and revolves body (2) with line and contact, and can do relative rotatablely moving for axis by circuit (1).

2. as the described rotatable plug of claim (1), it is characterized in that:

The conductor (11) that the A line revolves in body (2) and the circuit (1) is connected; The B plug revolves body (4) and is connected with plug body (5); The C line revolve body (2) outsourcing plug revolve body (4) or in be contained in plug and revolve body (4).

3. as the using method of the described rotatable plug of claim (1,2), it is characterized in that:

When plug (6) when not rotating, circuit (1) can revolve body (4) and line with plug and revolve body (2) and do with from rotatablely moving as axle; Equally, at circuit (1) when not rotating, plug (6) can revolve body (4) and line with plug and revolve body (2) to do with circuit (1) be rotatablely moving of axle.
