[1. First Embodiment]
(1) Configuration The charger according to the present embodiment includes a resin charger body 1 that holds a battery B as shown in FIG. As shown in FIG. 2, the charger main body 1 includes a holding portion 2 including a concave portion whose upper portion is open, and the battery B or a device incorporating the battery B is held in the holding portion 2. As shown in FIGS. 2 and 8, a plurality of power supply terminals 3 are provided at one end in the longitudinal direction of the holding portion 2. These power supply terminals 3 are arranged at predetermined intervals in the width direction of the holding portion 2 so that the upper surfaces thereof are exposed. The plurality of power supply terminals 3 are arranged on the upper surface of the terminal substrate 4, and are partitioned by a comb-shaped holder 5 provided above the power supply terminals 3. The terminal board 4, the power supply terminal 3, and the holder 5 are configured as separate members from the charger main body 1, and are fixed to the charger main body 1 by means such as screwing.

  A plate-shaped protective cover 6 that covers the power supply terminal 3 is provided above the power supply terminal 3. The protective cover 6 is a resin molded product that is a separate member from the charger body 1. As shown in FIG. 3, left and right brackets 7 are provided integrally with the protective cover 6 on both side edges of the protective cover 6. Each bracket 7 is a substantially triangular or fan-shaped member having a wide protective cover 6 side and a thin side opposite to the protective cover 6 (referred to as the front end side), and a shaft 8 that protrudes outward in the horizontal direction is integrally formed at the front end side. Is formed.

  As shown in FIG. 4, circular holes 9 that rotatably support the left and right shafts 8 of the bracket 7 are provided on the left and right sides of the holding portion 2. The circular hole 9 is opened horizontally from the inner wall surface of the holding portion 2 toward the outside. Above the receiving part on the inner wall surface of the holding part 2, an inclined surface 10 whose upper part opens outward is provided. The inclined surface 10 guides the end portion of the shaft 8 of the bracket 7. When the bracket 7 is pushed in from above the holding portion 2, the shaft 8 slides on the inclined surface 10 while the bracket 7 is elastically deformed. Thus, the shaft 8 is easily fitted into the circular hole 9. That is, the bearing portion in the present invention is constituted by the shaft 8 and the circular hole 9.

  As shown in FIG. 3, a hook-like engaged portion 11 protrudes from the inner surface of the protective cover 6, that is, the surface facing the power supply terminal 3. As will be described later, the engaged portion 11 meshes with an engaging member 12 provided in the charger main body 1.

  A support protrusion 13 is provided on the inner surface of one of the brackets 7 by extending the shaft 8 toward the inside of the bracket 7. The protective projection 6 is inserted into the coil portion of the torsion spring 14 that urges the protective cover 6 toward the covering position of the power supply terminal 3. The end portion of the first arm of the torsion spring 14 is engaged with a locking claw 15 provided in the vicinity of the protective cover 6 of the bracket 7. The end portion of the second arm of the torsion spring 14 is engaged with a stopper 16 provided on the charger main body 1 as shown in FIG.

  As shown in FIG. 2, a lock claw 17 for the battery B is provided above the power supply terminal 3 in the holding unit 2. As shown in FIG. 10, the lock claw 17 is provided at the tip of a lock arm 18 protruding upward from the bottom portion of the holding portion 2, and is formed in a lock recess 19 provided at one end of the battery B. Engage. The lock arm 18 and the lock claw 17 are integrally formed with the charger main body 1 with resin, and the lock arm 18 is movable in the longitudinal direction of the holding portion 2 by elastic deformation.

  A storage portion 20 for the protective cover 6 is provided on the side of the holding portion 2 opposite to the lock claw 17 across the power supply terminal 3. The storage portion 20 is formed by a space portion that is provided at the bottom of the holding portion 2 and extends in the vertical direction. That is, the vertical depth of the space portion is slightly larger than the length of the protective cover 6 (the length along the longitudinal direction of the holding portion 2), and the width of the space portion is slightly larger than the width of the protective cover 6. Thus, when the protective cover 6 is positioned in the storage unit 20, the size and shape are such that the battery B mounted in the holding unit 2 and the protective cover 6 do not interfere with each other.

  A lock / release arm 21 extending upward from the bottom of the storage unit 20 is provided on the power supply terminal 3 side of the storage unit 20, that is, on the protective cover 6 side. The lock / release arm 21 is integrally formed with the charger main body 1 with resin, and only the root portion thereof is fixed to the charger main body 1, and the distal end side thereof can be elastically deformed. The tip of the lock / release arm 21 protrudes from the mounting surface of the battery B in the holding unit 2, and when the battery B is mounted on the holding unit 2, it is pushed by the bottom of the battery B and deforms to the power supply terminal 3 side. .

  On the surface of the lock / release arm 21 opposite to the power supply terminal 3, a protruding engagement member 12 is provided that meshes with the engaged portion 11 of the protective cover 6 located in the storage portion 20. The engagement dimension between the engagement member 12 and the engaged portion 11 is such that the engagement between the engagement member 12 and the engaged portion 11 is released when the lock / release arm 21 is pressed and deformed by the battery B. In the state where the lock / release arm 21 is not deformed, the engagement between the engaging member 12 and the engaged portion 11 is maintained.

(2) Operation The operation of the charger according to this embodiment is as follows.
In a state where the battery B is not mounted in the charger main body 1, the protective cover 6 is urged toward the power supply terminal 3 by the force of the torsion spring 14 as shown in FIGS. A plurality of power supply terminals 3 are covered. Therefore, even if the charger main body 1 is empty, the power feeding terminal 3 is not exposed to the outside, so that a dustproof effect can be obtained and there is no possibility of inconvenience such as a short circuit.

  When the battery B is mounted in the charger body 1, the power supply terminal 3 is exposed by rotating the protective cover 6 toward the storage unit 20 with the user's fingertip against the force of the torsion spring 14. When the protective cover 6 is completely rotated into the storage portion 20, the engaging member 12 of the lock / release arm 21 is engaged with the engaged portion 11 provided inside the protective cover 6, and even if the fingertip is released, it is protected. The cover 6 cannot be restored.

  In this state, as shown in FIG. 10A, the end of the battery B opposite to the power receiving terminal is inserted into the holding portion 2, and the battery B is rotated about the portion as the shaft 8. As a result, the power receiving terminal of the battery B can be connected to the power supply terminal 3 of the charger body 1 and charging is started. At this time, as shown in FIG. 10 (b), the battery B is locked in the holding portion 2 by engaging the claw of the lock arm 18 with the locking recess 19 provided on the power receiving terminal side of the battery B. Is done.

  At the same time, the bottom of the battery B mounted in the holding unit 2 presses the tip of the lock / release arm 21, so that the lock / release arm 21 is deformed to the side opposite to the power supply terminal 3. As a result, the engagement member 12 of the lock / release arm 21 and the engaged portion 11 of the protective cover 6 are disengaged, and the protective cover 6 can be rotated to the power supply terminal 3 side by the force of the torsion spring 14. . However, in this state, since the battery B is mounted in the holding unit 2 and is fixed by the lock arm 18, the protective cover 6 is pushed by the battery B and stops in the storage unit 20.

  When the fully charged battery B is taken out from the holding portion 2, the pressing force of the battery B holding the protective cover 6 is lost, so the protective cover 6 is rotated toward the power supply terminal 3 by the force of the torsion spring 14. To do. As a result, the power supply terminal 3 taken out of the battery B and exposed is immediately covered with the protective cover 6.

(3) Effects According to the present embodiment, the following effects are exhibited.

(A) When the protective cover 6 is rotated and the power supply terminal 3 is exposed before the battery B is mounted, the protective cover 6 is locked by the lock / release arm 21, so that the protective cover 6 may not be pressed. The battery B can be attached to the charger body 1 from which the power supply terminal 3 is exposed. As a result, the battery B can be easily attached to the charger body 1.

(B) Since the lock of the protective cover 6 is released by the force when the battery B is attached to the charger main body 1, the protective cover 6 automatically covers the power supply terminal 3 when the battery B is taken out. Therefore, the user does not forget to cover the power supply terminal 3, and is excellent in safety and has a high dustproof effect.

(C) In the present embodiment, the protective cover 6, the torsion spring 14, and the charger main body 1 are formed of a pair of members. Automatic coating can be achieved. Therefore, it is possible to reduce the number of parts and assembly man-hours.

(D) By providing the storage unit 20 in the vertical direction at the bottom of the holding unit 2, the protective cover 6 in a state where the power supply terminal 3 is not covered does not interfere with the battery B mounted in the holding unit 2, and is charged. An increase in the size of the main body 1 can be avoided.

(E) Since the engaging direction of the engaging member 12 and the engaged portion 11 is opposite to the pressing direction of the lock / release arm 21 by the battery B, the battery B is mounted in the holding portion 2. The engagement between the engagement member 12 and the engaged portion 11 can be reliably released, and the protective cover 6 can reliably cover the power supply terminal 3 without the battery B attached.
