Description

The anchoring that can be used for mobile phone earphone

The utility model relates to the anchoring that can be used for mobile phone earphone, is specifically related to a kind of anchoring that can be used for mobile phone earphone.

For ease of answering mobile phone and preventing electromagnetic width of cloth projection sound health, people often use earphone to answer mobile phone, for ease of carrying and using, popular in the market a kind of earphone anchoring with lead contractile function, although it is multiple that this device has, but its structure all is identical, this device does not break when spurring for solving, all adopt in end of incoming cables and rotating annular conductive ring and join, the structure that leading-out terminal is connected with contact, this structure contact when the pulling lead is in dynamic the connection with annular ring, realized freely stretching of lead, but the connection conduction mode of this structure exists skimming wear and loose contact, thereby influences the useful life of speech quality and device owing to be dynamic connection.

Advantages such as the purpose of this utility model provides a kind of improved anchoring that can be used for mobile phone earphone, and it is reliable, simple in structure that this device has the conducting of connection, and the easy to use and life-span is long.

The utility model adopts following technical scheme to realize: construct a kind of anchoring that can be used for mobile phone earphone, comprise housing, be located at the winding roll in the described housing, fixing cord and scalable lead, can drive the spiral spring that described winding roll rotates, the take-up of the described winding roll rotation direction of may command, the disk body of described winding roll is provided with the cannelure that is used to twine described flexible lead, at least also have on the disk body of described winding roll more than one and the flexible coaxial cannelure of lead cannelure of described winding, be wound with the flexible wire that multi-turn can be in rolling-in or relaxed state with the difference of described winding roll rotation direction respectively in the described coaxial cannelure, one end of described flexible wire is connected with an end of fixing cord, and its other end is connected with an end of scalable lead.

In the above-mentioned anchoring that can be used for mobile phone earphone that provides according to the utility model, the length of described flexible wire is shorter than the length of scalable lead.

In the above-mentioned anchoring that can be used for mobile phone earphone that provides according to the utility model, the other end of described fixing cord can be connected to signal input, out splice going splice or signal output conversion device, and the other end of described flexible lead can be connected to the signal output conversion device or signal is imported, out splice going splice.

In the above-mentioned anchoring that can be used for mobile phone earphone that provides according to the utility model, described take-up comprises the take-up button, be sleeved on the back-moving spring in the described button, one end of described shift knob is provided with positioning cards, the end face of described winding roll is provided with and the suitable groove of described positioning cards, and described positioning cards can slide in described groove and skid off.

Implement the anchoring that can be used for mobile phone earphone described in the utility model, but employing rolling-in and loose flexible wire replace the dynamic jockey in the original structure, the two ends of flexible wire tightly link together with the turnover lead all the time, when the pulling line stretcher, can not produce the situation of loose contact, just make flexible wire be in rolling-in or relaxed state, two end connectors can not become flexible, overcome the skimming wear of dynamic contact device and produced problems such as loose contact, guaranteed speech quality, because of fricton-tight parts, so long service life.

Further specify the utility model below in conjunction with accompanying drawing with embodiment, in the accompanying drawing:

Fig. 1 is the structural representation of the housing of anchoring described in the utility model when opening;

Fig. 2 is the sectional structure schematic diagram after housing installs;

As shown in Figure 1, the anchoring that can be used for mobile phone earphone that is provided by the utility model comprises two halves sandwich type element 12, in the housing inner chamber, be provided with a winding roll 11 that is used for spiral, in winding roll 11, be provided with a spiral cannelure 15 that is used to twine scalable lead 14, in winding roll 11, also be provided with the coaxial cannelure 16 of one or more and described spiral cannelure 15, in groove, be wound with the lead 10 of multi-turn flexibility, described flexible wire 10 can be in rolling-in or relaxed state respectively along with the difference of winding roll 11 rotation directions, the two ends of flexible wire 10 are connected with an end of scalable lead 14 and fixing cord 13 respectively, for realizing automatic recovery, in housing, also be provided with the spiral spring 21 and the take-up that are the clockwork spring shape to scalable lead.

As shown in Figure 2, described take-up is a kind of mechanism that is similar to the click function that has, in device, be provided with take-up button 17, in button 17, be set with back-moving spring 18, end at button 17 is provided with positioning cards 20, be provided with and slide into the more than one groove 19 that skids off for described positioning cards 20 at the end face of winding roll 11 position corresponding to positioning cards 20, when the scalable lead 14 of pulling, described positioning cards 20 can slide into from a groove along the end face of winding roll and make described winding roll 11 be in rotation or positioning states respectively another groove, prevent winding roll 11 counter-rotatings, Mainspring type spiral spring 21 is tightened simultaneously, scalable lead 14 is drawn out and is in user mode, can press button 17 when needing to regain lead 14 makes positioning cards 20 break away from groove 19, position-limiting action cancellation, winding roll 11 reverses under the effect of take-up spring 21 and the lead 14 that will stretch twines in the backrush wire casing 15 and realizes automatic wire winding function.

For making the longer service life of flexible wire 10, can adopt a kind of silver-plated cable with flat of high strength external packing is flexible wire, and the length of flexible wire can be shorter than the length of scalable lead.
