In the flexible connector, the mechanical connection portion is formed as an uneven fitting portion on the side surface of the charger, and the electrical connecting portion is provided in the uneven fitting portion, which is the mechanical connecting portion, and is mechanically connected. The connection of the parts is made before the connection of the electrical connection part, and the mechanical connection part is a concave groove composed of a vertical groove on the back side and a horizontal groove on the bottom side of one of the chargers. And an engaging protrusion provided on the side surface of the other charger and having a shape corresponding to the concave groove, and the engaging convex portion is inserted from the side into the concave groove opened to the side. Yes, the connection to which the part to be charged is connected is on the upper surface of the bottom of the charger, It is characterized in that the longitudinal groove portion in the groove is disposed on the side surface of the rear wall that rises. [Operation] According to the present invention, the connection strength of the mechanical connection between one side of the charger and the other side of the other charger can be kept high, and the reliability of the electrical connection is increased. be able to. [Embodiment] Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings. As shown in FIG. 2, the illustrated example shows a charger for charging a storage battery 30 incorporated in the electric toothbrush 3. ing.
The charger here is a main charger 1 and this main charger 1
Are connected to each other, and the child charger 2 is configured to be able to connect another child charger 2. As shown in FIG. 3, the parent charger 1 has a step-down transformer 14, a rectifier circuit and a charge control circuit mounted in a rectangular parallelepiped housing 10 having a notch 11 opened laterally and upwardly and forwardly on one side. With a built-in printed circuit board 15,
As shown in FIG. 3 (c), the housing 10 has concave grooves 12 connected to each other on the side where the notch 11 is provided and on the lower side of the notch 11 and the side surface of the back of the notch 11. In the concave groove 12, feed terminals 18, 18 disposed at the other end of a pair of terminal plates 16, 16 arranged in the housing 10 and having one end connected to the printed circuit board 15 are located. ing. The terminal plates 16, 16 disposed below the notch 11 are connected to charging terminals 17, 17, respectively, and these charging terminals 17, 17 are projected portions located below the notch 11. It is arranged in 13. On the other hand, the child charger 2 has an L-shaped vertical section having cutouts 21 opened on both sides and upward and forward, and a concave groove 22 similar to that of the main charger 1 is provided on one side thereof. On the other side, an engaging projection 23 is provided. The connection terminals 29, 29 at one end of the pair of terminal plates 26, 26 disposed inside are located in the engagement projection 23, and the feed terminals 28, 28 at the other end are located in the concave groove 22. And the charging terminals 27 connected to the terminal plates 26, 26,
27 is located in a projection 24 that projects into the notch 21. The engaging protrusion 23 is inserted into the groove 12 of the parent charger 1 or the groove 22 of the other child charger 2, and at this time, it engages with the inner surfaces of the grooves 12, 22 and is careless. Protrusions 25, 25 are provided to prevent slippage. Thus, in this charger, the engaging projection 23 of the sub charger 2 is inserted into the concave groove 12 on one side of the main charger 1,
If the two are mechanically connected, the feed terminal 18 is connected to the connection terminals 29,2.
9 are connected to each other, an electrical connection is made. As shown in FIG. 2, two electric toothbrushes 3, 3 are provided.
Are connected to the projection 13 of the parent charger 1 and the projection 24 of the child charger 2, respectively.
1 is connected, and these storage batteries 30, 30 can be charged simultaneously. When the number of storage batteries to be charged is large, the engagement protrusion 23 of another child charger 2 is inserted into the concave groove 22 of the child charger 2, and the connection terminal 29 is connected to the feed terminal 28. As shown in the figure, a plurality of child chargers 2 can be connected. When connecting the child charger 2 to the parent charger 1 and further connecting the other child charger 2 to the child charger 2, the mechanical strength between the two connected to each other is reduced by a concave groove on one side. 12,22
And the engagement with the engagement protrusion 23 on the other side, the concave grooves 12 and 22 here are formed along two sides of the side surface of the parent charger 1 or the child charger 2. L-shaped, and the corresponding engaging projection 23 is
Is formed along the two sides of the side surface, the mechanical coupling portion is configured as a concave / convex fitting portion for performing concave / convex fitting on substantially the entire side surface. The mechanical strength is high. Moreover, the electrical connection portion is provided in the concave / convex fitting portion which is the mechanical connection portion, and the feed terminals 18 and 28 are in the concave grooves 12 and 22, as shown in FIGS. As is apparent from the fact that the connection terminal 29 is inside the engagement projection 23, the connection of the mechanical connection is made before the connection of the electrical connection, so that the electrical connection Has also become more reliable. When only the parent charger 1 is used, the parent charger 1 is used.
The groove 12 remains open on the side surface of the sub charger 2 and the feed terminal 18 is exposed. In addition, when the sub charger 2 is connected, the feed terminal 28 is exposed in the groove 22 of the sub charger 2. In this case, the end cap 4 having the engaging convex portion 41 detachably engaged with the concave groove 12 or the concave groove 22 is prepared to prevent the feed terminals 18 and 28 from being exposed. . In the figure, reference numeral 7 denotes a light-emitting element provided in the main charger 1 for displaying during charging, and reference numeral 19 denotes a color-coded sticker attached to a concave portion provided in the main charger 1 or the sub charger 2. The color-coded seal 19 corresponds to the color-coded seal 33 attached to the portion of the electric toothbrush 3 surrounded by the annular rib,
This allows the user to distinguish his / her own electric toothbrush 3 and charger. The charger shown here has a suction cup 6 on its bottom surface so that it does not move when the electric toothbrush 3 is inserted or removed.
Is attached. As shown in FIG. 5, the suction cup 6 having a screw insertion hole 60 and having a sealing annular rib 61 on the end face as shown in FIG.
As shown in FIG. 6, attached by screws 62,
In other words, a material that is sealed by the head of the screw 62 and the rib 61 can be used. At this time, if the convex portion 45 is provided on the suction cup mounting portion on the housing 10 side, the suction cup 6 is pressed as shown in FIGS. In this case, the internal air can be reduced. As shown in FIGS. 8 to 10, a large-diameter hole 46 and a small-diameter hole 47 are provided continuously on the bottom surface of the housing 10, and
A sucker 6 having a head 63 through a thin neck portion 64 is used. After the head 63 is put into the housing 10 through the large-diameter hole 46, it is moved to the small-diameter hole 47 side so as to be attached. May be done. In addition, this charger is for the electric toothbrush 3 as described above, and since it is expected that toothpaste containing salt is used for brushing the teeth, a titanium material is used for each terminal here. And avoid electric erosion.
