Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the structural schematic diagram of existing multimedia loudspeaker box detection fixture.
Specific implementation mode
With reference to embodiment, technical scheme of the present invention is described in further detail, but do not constituted pair
Any restrictions of the present invention.
A kind of described referring to Fig.1, the of the invention general multimedia loudspeaker box detection fixture, including pedestal 1, wherein in institute
It is symmetrically arranged with positive conducting bar 2 and negative sense conducting bar 3 on the pedestal 1 stated, is arranged on the positive conducting bar 2 and negative sense conducting bar 3
Positive conducting bar 2 or negative sense conducting bar 3 can be made to be fixed on pedestal 1 or the rotating fixing machine 4 of rotation, in the forward direction
It is provided with the positive fixed seat 5 being connect with pure tone machine on conducting bar 2, is provided on the negative sense conducting bar 3 and is connect with pure tone machine
Negative sense fixed seat 6.In detection loudspeaker weld tabs, worker first unclamps rotating fixing machine 4, as required the loudspeaker weldering of detection
The relative distance that positive conducting bar 2 and negative sense conducting bar 3 are adjusted apart from size of piece, then each is needed to the loudspeaker weld tabs of detection
Positively and negatively contacted respectively with positive conducting bar 2 and negative sense conducting bar 3, can be carried out detection using pure tone machine.Positive conducting bar 2
With negative sense conducting bar 3 can increase with the contact area of loudspeaker weld tabs, keep contact more stable, detection result is more acurrate；Due to positive guide
It is provided with rotating fixing machine 4 on item 2 and negative sense conducting bar 3, it both can be by positive conducting bar 2 and negative sense conducive to rotating fixing machine 4
Conducting bar 3 is fixed on substrate 1, the distance between conducting bar can also be adjusted by rotating positive conducting bar 2 and negative sense conducting bar 3, with inspection
The loudspeaker weld tabs of different model is listened, can be with the loudspeaker weld tabs of 20,27,31 series of detection, versatility is wider, can also save replacement
The time of detection fixture, to improve production efficiency.
The positive conducting bar 2 and negative sense conducting bar 3 are the identical cuboid copper sheet of shape, in this way, positive conducting bar 2 and negative sense
For conducting bar 3 than the area bigger that existing fixture is contacted with loudspeaker weld tabs, circuit connection can be more stable.2 He of positive conducting bar
3 length of negative sense conducting bar is 60mm, width 6mm, thickness 3mm, this size of positive conducting bar 2 and negative sense conducting bar 3 makes it more
Good placement on substrate 1, and makes it more preferably be contacted with loudspeaker weld tabs.
The rotating fixing machine 4 be a diameter of 4 centimetre of the screw external with positive conducting bar 2 or negative sense conducting bar 3 and
Nut.Positive conducting bar 2 and negative sense conducting bar 3 are rotated when replacing detection loudspeaker weld tabs model, after screw is unclamped to adjust forward direction
Distance between conducting bar 2 and negative sense conducting bar 3, so that it may with the loudspeaker weld tabs of detection different model；It adjusts positive conducting bar 2 and negative sense is led
Item 3 tightens screw after, so that it may to fix on substrate 1 positive conducting bar 2 and negative sense conducting bar 3.
The positive fixed seat 5 is the screw fixing button being connect with positive conducting bar 2, the negative sense fixed seat 6 be with
The screw fixing button that negative sense conducting bar 3 connects fixes contact wire using screw fixing button and loosening is effectively prevent to cause poor contact,
Keep circuit connection more stable, detection is more acurrate.
The positive fixed seat 5 is connect with the positive signal output end of pure tone machine, the negative sense fixed seat 6 and pure tone
The negative signal input terminal of machine connects.Using pure tone machine 2 transmission circuit signal of conducting bar to the forward, if when loudspeaker weld tabs no problem,
Circuit signal can be sent to cathode direction from the positive extreme direction of loudspeaker weld tabs, be resent to negative sense conducting bar 3 and return to the negative of survey pole machine
Pole after so that pure tone machine is received the circuit signal of cathode, sends out regular prompt sound.
The pedestal 1 is bakelite plate, insulate since bakelite plate has, does not generate the characteristics such as electrostatic, wear-resisting and high temperature resistant,
It is more suitable for the requirement of substrate 1.
The foregoing is merely presently preferred embodiments of the present invention, it is all within the scope of the spirit and principles in the present invention made by it is any
