Description

Improved automatic winding box

The utility model relates to a kind of automatic winding box, particularly a kind of durable, automatic winding box of earphone sound source wire of avoiding noise to disturb.

See also shown in Figure 1, general automatic winding box 1 commonly used, be to utilize this little spring 111, little copper pearl 112, little copper sheet 11 that furls 11 times quadrate parts settings of dish commonly used, utilize this not the elastic force of upper spring 111 should be little copper pearl 112 eject downwards with little copper sheet 113, be in contact with one another with the conducting strip 13 of this lower cover 12 commonly used, make this earphone cord 14 and Outlet line 15 mutual conduction of being somebody's turn to do lower cover 12 commonly used that furls in the dish 11 commonly used.

But, should use automatic take-up 1 always by this little spring 111, little copper pearl 112, little copper sheet 11 and these conducting strip 13 contacted modes, usually can be because of the elastic fatigue of this little spring 111, and this little copper pearl 112, little copper sheet 113 can't be ejected downwards, cause earphone signal to interrupt, even can't use fully, the durability of this automatic winding box 1 commonly used is had a greatly reduced quality; Assemble dish 11 o'clock that furl commonly used of this automatic winding box 1 commonly used again, because of the body of this little spring 111, little copper pearl 112, little copper sheet 113 is too small, cause the producer to assemble inconvenience, the assembly time is long, wastes man-hour etc., is often scolded by maker.

Spiral seat 16 commonly used that furls dish 11 tops commonly used that should automatic winding box 1 commonly used be for single circle body and surface be to be a smooth side; make this commonly used when furling dish 11 and furling this earphone cord 14; the tight more phenomenon that is difficult to fold takes place to change more in regular meeting, reduces take-up speed and accuracy.

The runner commonly used 18 set guide cards 181 that should use trigger group commonly used 17 belows of automatic winding box 1 always are for tabular always; in the time of should using guide pillar 191 these guide cards 181 of importing of trigger 19 belows always; be easy to generate inharmonic collision; after using a period of time; regular meeting causes this guide pillar 191 can't import this guide card 181; make this automatic winding box 1 commonly used can't normally block only this earphone cord 14, often scolded part by the customer, this automatic winding box shortcoming commonly used is comprehensively as follows:

1, this automatic winding box commonly used is by this little spring, little copper pearl, little copper sheet and the contacted mode of this conducting strip; usually can be because of the elastic fatigue of this little spring; and this little copper pearl, little copper sheet can't be ejected fully, cause earphone signal to interrupt, even can't use fully.

2, the body of this little spring, little copper pearl, little copper sheet is too small, causes the producer to assemble inconvenience, and the assembly time is long, wastes man-hour etc., is often scolded by maker.

3, the spiral seat commonly used that furls the dish top commonly used of automatic winding box commonly used be for single circle body and surface be to be a smooth side; this commonly used furling is coiled when receiving this earphone cord; the tight more phenomenon that is difficult to fold takes place to change more in regular meeting, reduces its take-up speed and accuracy.

4, the set guide card of runner commonly used of the trigger group commonly used below of this automatic winding box commonly used is for tabular always; when the guide pillar of this trigger commonly used below imports this guide card; be easy to generate inharmonic collision; after using a period of time; regular meeting causes this guide pillar can't import this guide card, makes this automatic winding box commonly used can't normally block only this earphone cord.
