It is possible to effectively prevent the portion from being damaged.

  Furthermore, the unit case 21 shown in the figure includes a holding mechanism 27 for holding the unit substrate 24 stored in the storage recess 22 inside the storage recess 22. The holding mechanism 27 shown in FIGS. 11, 14, and 15 includes a plurality of locking arms 33 formed integrally with the unit case 21. The locking arm 33 includes an elastic arm portion 33A extending toward the opening 23 of the storage recess 22 and a hook portion 33B provided at the tip of the elastic arm portion 33A.

The holding mechanism 27 holds and holds both ends of the unit substrate 24 inserted between the locking arms 33 facing each other with hook portions 33B. When the unit substrate 24 is mounted, the opposing locking arms 33 elastically deform the elastic arm portion 33A in the direction in which the opposing hook portion 33B is separated to pass the unit substrate 24 between the hook portions 33B. After passing through the substrate 24, the elastic arm portion 33A returns to its original shape, and both ends of the unit substrate 24 are elastically locked by the opposing hook portions 33B.

There are features. This is because the peripheral wall 21B can prevent water such as rainwater from entering, or prevent foreign matter such as dust from entering. Even when the portable power supply device is accidentally dropped, the impact received by the unit case 21 can be supported by the end surface 2X of the main body case 2 via the peripheral wall 21B. There is also a feature that can reduce the effect on the connecting portion with the side terminal 28. For this reason, it is possible to reduce the load due to impact such as dropping on the connection portion between the unit side terminal 28 and the unit substrate 24 and the connection portion between the power supply terminal 8 and the circuit board 4 and damage these connection portions. Can be effectively prevented.

This light emitting unit has an advantage that a mechanical connection structure between the light emitting unit and the main body case can be strengthened by inserting a plurality of unit side terminals into a plurality of power supply terminals. For this reason, the twist, the inclination, and the impact at the time of insertion / extraction or dropping can be effectively suppressed, and adverse effects such as poor connection can be reliably prevented. In particular, even if a connection portion between one unit-side terminal and the circuit board becomes defective, the power supply can be maintained through the other unit-side terminal. Further, in a light emitting unit including two unit side terminals, either one of the unit side terminals can be used as a dummy terminal. This light-emitting unit can strengthen the mechanical connection structure between the light-emitting unit and the main body case by using the dummy terminal as a dedicated connection member, and can more effectively suppress twisting, tilting and deformation of the unit-side terminal. .

The light emitting unit 60 is disposed so as to face the end surface 62X of the main body case 62 in a state where the unit side terminal 28 is inserted into the power supply terminal 8, is physically connected to the power supply device main body 60, and electrically Connected. The power generation unit 80 is supplied with electric power from the power supply device main body 60 by turning on the power supply switch 13 provided on the upper surface of the main body case 62 in a state where the unit side terminal 28 and the power supply terminal 8 are electrically connected. The semiconductor light emitting element 25 to be turned on lights up.

  In the portable power supply device of the above embodiment, the outer shapes of the end faces of the peripheral walls 21B and 81B of the unit cases 21 and 81 are substantially equal to the outer shapes of the end faces 2X and 62X of the main body cases 2 and 62, and the peripheral walls 21B and 81B The end surface is in contact with the outer peripheral edge of the end surfaces 2X and 62X of the main body cases 2 and 62. However, although the unit case is not shown, the inner shape of the end surface of the peripheral wall is substantially equal to the outer shape of the end surface of the main body case, that is, the inner shape of the peripheral wall is substantially equal to the outer shape of the end portion of the main body case. It is also possible to adopt a structure in which the end of the main body case is fitted and connected to the inside. Since this structure can cover the end face side of the main body case with the unit case in a sealed state, it has a feature that it can more effectively prevent intrusion of water such as rain water or dust. Furthermore, there is also a feature that the light emitting unit can be effectively prevented from being unexpectedly detached from the main body case by fitting the peripheral wall of the unit case to the main body case.

  A portable power supply device according to the present invention is a semiconductor of a light emitting unit to be mounted while being preferably used as an emergency charger for charging a mobile phone or a portable music player, or a charger for charging an emergency charger. The light emitting element can be used as a lighting device by emitting light.
