  However, in the case of integrally forming a waterproof rib on the battery lid by insert molding, the rib formed on the back surface of the battery lid by placing the battery lid made of PC resin or the like once molded in a high-temperature molding die Since silicon or the like is insert-molded, there is a problem that the battery lid is scratched at the time of molding or the appearance of the mold is deteriorated due to a mold-clamping mark.

  In addition, in the case where the internal waterproof holder is attached to the battery lid, silicon is insert-molded into a rib formed on a holder separate from the battery lid, so even if the appearance of the holder deteriorates during molding, There is no problem because it is hidden. However, in the case where the holder is attached to the back surface of the battery lid, there is a problem that if the attaching accuracy is poor, a gap is formed and the waterproof performance cannot be exhibited. For this reason, it was necessary to give the battery lid itself a backlash. In addition to the thickness of the internal holder, the thickness of the double-sided adhesive tape is required, and it has been difficult to reduce the thickness.

  Further, even when the rear cover plate is provided as in the above-mentioned Patent Document 1, there is no problem in appearance, but since the rechargeable battery cannot be taken out unless the rear cover plate is removed, it is troublesome to take out and attach the rechargeable battery. .

  According to the above configuration, the packing holder is a separate part from the removable cover that appears in the appearance, so that the appearance does not deteriorate even if silicon packing is integrally formed in the packing holder. In addition, since the packing holder is formed on the back surface of the removable cover so that the position can be changed, it is not necessary to strictly manage the mounting accuracy of the packing holder, the manufacturing cost is reduced, and it can be moved to the best position. Waterproof performance is improved. Further, since it is not necessary to make the detachable cover itself have a backlash to absorb manufacturing errors, there is no variation in ease of removal for each product, and the appearance is good. In addition, since it is not necessary to bond the packing holder or the removable cover, the packing holder can be easily replaced at a low cost.

In the second invention, in the first invention,
A plurality of ribs having long holes are erected on the back surface of the removable cover,
The packing holder is provided with a locking portion that is locked in the long hole.

  According to said structure, a packing holder can be attached to the back surface of a detachable cover by a simple structure so that a position change is possible.

In the third invention, in the first or second invention,
The packing holder is formed in a dish shape with a peripheral wall standing so as to cover the entire rechargeable battery, and the peripheral wall is connected by a film.

  According to said structure, since it can be made thinner than the minimum thickness of resin if it is a film, the thickness of a portable terminal can be made thin.

In a fourth invention, in any one of the first to third inventions,
The electronic component is a rectangular plate-shaped rechargeable battery,
The packing holder is formed in a dish shape with a peripheral wall standing so as to cover the entire rechargeable battery, and the peripheral wall of the corner is lower than the peripheral wall of the other part.

  According to said structure, since the corner | angular part of a corner | angular part can be made low and the corner | angular part of a rechargeable battery can be covered with the bulging part of an accommodation recessed part, a rechargeable battery does not wobble.

  As described above, according to the present invention, by attaching the packing holder surrounding the housing recess in a waterproof state to the removable cover so that the position can be changed, the removable cover can be thinned and the mounting accuracy can be improved. It can be easily installed without worrying.
