Description

[Detailed Description of the Invention] The present invention relates to a flat power supply device in which a charging power plug is provided in a main body case containing a built-in storage battery so that the charging power plug can be inserted into and taken out from the main body case. To provide a structure in which a charging power plug can be securely fixed when it is taken in and out of a case.

Hereinafter, the present invention will be explained based on drawings showing an example of a live gun. Figure 1 a+b, c- shows the external appearance of the back power supply device. 1 is a main body case made of synthetic resin and is made of J-shaped molding. This main case is composed of an upper case 1a and a lower case 1b that can be separated. has been done. 2 and 3 are tapping screws for fixing the upper case 1a to the lower case 1b, 4 and 5 are positive and negative terminals of the four storage batteries built into the main body case 1, and 6 is a charge display. It is a light emitting diode, and the tip of this light emitting diode 6 is exposed to a window 7 provided in the upper case 1a.

Reference numeral 8 denotes a charging power supply plug that is provided in parallel to the main body case 1 so as to be freely inserted into and taken out from the main body case 1. Reference numeral 9 denotes a cover that fixes the movement of the charging power supply plug 8.

Figure 2 shows the lower case 1b with the upper case 1a removed. Reference numerals 10.11 are cylindrical sealed nickel-cadmium storage batteries connected in series, two each, and they are connected in parallel inside the lower case 1b. It is located. 12 is a charging transformer, 13 is a printed circuit board on which a rectifier 9, a light emitting diode 6, a resistor, etc. are attached;
It is fixed to the lower case 1b with tapping screws 14.

15 is electrically connected to the charging power supply plug 9.
l)- lead plate, this lead plate 15 is the charging transformer 1.
It is electrically connected to the primary winding of No. 2.

FIGS. 3a and 3b show a holding structure for the cover 9. Reference numeral 16 is a recess provided in the upper part of the main body case 1, and a shaft hole 17 is provided in the side wall of the recess 16. The cover 9 is pivotally supported so as to be openable and closable by fitting the shaft portion 9a into the shaft hole 17 of the recess 16.
, b, the protrusion 9b and the wedge-shaped elastic retaining portion 9C are integrally formed. Reference numeral 18 denotes a plug holder for holding the charging power plug 8, and the plug holder 18 is slidably held in holes 19 provided in the four parts 16 of the main body case 1, as shown in FIG. 5a.

It is configured as shown in b. Moreover, the elastic retaining portion 9C of the cup <-9 is adapted to elastically engage with the hole 19 of the main body case 1 when the cup <-9 is closed.

FIGS. 6a and 6b show the lead plate 15 in FIG. 2. This lead plate 15 is made of an electrically insulating material such as a baked plate, and the left and right sides of the lead plate 15 are made of elastic material. A phosphor-bronze plate 15a is fixed with copper iron 15b. The charging power supply plug 8 is connected to a phosphor bronze plate 1 fixed to a lead plate 15, as shown in FIG.
5a while sliding, and this phosphor bronze plate 1
Electricity is supplied to the primary winding of the charging transformer 12 via 5a.

The operation of each part in the above configuration will be explained.

In the pack power supply device of the present invention, a plurality of storage batteries 10
, 1.1, as shown in Figure 3,
Hold the plug holder 18 and pull the charging power supply plug 8 out of the main case 1. In this state, when the cover 9 is turned from the solid line state to the dotted line to close it, the elastic retaining portion 9C provided inside the cover 9 passes through the hole 19 of the main body case 1 and is elastically engaged. At the same time, one side surface 9b' of the protrusion 9b provided on the inside of the cover 9 comes into contact with one upper side surface 18a of the plug holder 18, so that the charging power supply plug 8 is fixed. In this case, since the elastic retaining portion 9C is configured in a wedge shape, it is easily inserted into the hole 9 of the main body case 1, and once inserted, it is difficult to come out due to the catch on the end surface 9d. It is. Therefore, when the charging power plug 8 is inserted into the power outlet in this state, the plurality of storage batteries 10, 11 are charged, and at the same time, the light emitting diodes 6 are lit to indicate that they are in the charging state.

In addition, in FIG. 3, 20 is provided in the main body case 1, and
The ribs 20 serve as guides in the sliding direction of the plug holder 18, and prevent vertical and horizontal vibrations.

Also, if you do not charge multiple storage batteries 10.11,
Holding the plug holder 18, the charging power supply plug 8 is housed in the main body case 1. In this state, when the cover 9 is rotated and closed, the elastic retaining portion 9C provided inside the cover 9 passes through the hole 19 of the main body case 1 and is elastically engaged with the cover 9. Since the other side surface 9b'' of the protrusion 9b provided on the inside contacts the other upper side surface 18b of the plug holder 18, the charging power supply plug 8 is fixed in this state.

As described above, according to the present invention, the charging power supply plug, which is provided in and out of the main body case, is inserted into the main case when it is pulled out of the main case for charging, and when it is pulled out of the main case for charging. When stored, the charging power plug is fixed to prevent the cover from being blocked, so even when charging the storage battery built into the main body case, it can be done in a stable state. The charging power plug stored inside the case comes out naturally and does not have any negative effects, and the cap is equipped with an elastic engagement part that elastically engages with the hole in the main case when it is closed. This tube prevents the cover from opening spontaneously and provides various excellent effects.
