Help fo find a battery lid assy

Rate this topic


Recommended Posts

For the most part, Sony MD units that take the gumstick batteries have the same design of positive battery terminal. Irrespective of how the actual electrical contact is arranged, the major part is a metal plate stamped and shaped with two 'fingers':

The finger at the far end of the plate has the end bent down, into a 'hockey stick' shape. This protruding 'peg' is designed to prevent the metal part sliding all the way out of the plastic battery compartment lid, by catching against a moulded 'bumper' on the plastic flap. To remove the battery flap this finger needs to be gently lifted with a tool such as a small screwdriver to allow the peg over the bumper, which will then slide off. If the battery lid keeps falling off, it is this metal finger that needs to be bent very slightly downwards, so that it catches against the plastic bumper again when the metal part is replaced into the plastic.

The inner most metal finger, which tapers, also bends downwards, with a hooked end. This part is designed to ride up over a further moulded part on the plastic, in this case an upwardly sloping 'hill'. It is this part that gives the flap some 'friction' when the door is closed, thus holding the door firmly shut. If the battery flap opens too easily, and you find the battery falling out on its own, this finger again needs to be bent further downwards to apply more pressure on the 'hill' when fully closed.

Of course, if the terminal hinge is broken, or the contacts heavily corroded, replacement is really the only solution.

Hello everyone;

I tried to do what you recommended but the plastic is missing one of two "walls " of the slide to introduce the contact.

Thank you for the suggestions that I will definitely be useful.

Sony Italy has provided 15 days between the parts and I will be able to replace it.

Thanks again to all

Hello Stephen,

I did not know the machine Qualia; is really a big beautiful object.

A little expensive as the price.

You have no idea where he could buy one?

and .......... you borrowed 800 / 1000 dollars to compare? :-)

Good evening all

sergio

Sorry Sergio, somehow I missed this. No, I do not own a Qualia. Maybe in my next lifetime......
