Description

[Detailed description of the invention] The present invention relates to a charger, and the charging parts and charging contacts, etc. that are incorporated into the charger case are assembled into a unit outside the case, and the charger can be used simply by attaching this unit to the main body case. The purpose is to improve assembly workability.

In the conventional device, charging contacts and charging components were attached to predetermined locations on the case one by one from the back of the case, which resulted in long assembly time and poor workability.

The present invention has been devised in view of these points, and one embodiment thereof will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the charger case is composed of a main case 1 and a bottom cover 2. Battery storage recesses 3, 3 are formed on the top surface of the main case 1, and the main case 1 and A charging contact piece and parts required for charging are stored in the space between the bottom cover 2 and the bottom cover 2.

In Fig. 3, 4 is a support and holding plates 5, 5 are provided on both sides.
The front surface of each holding plate 5 has a pair of recessed steps 6, 6, and the insertion opening edge of each recessed step 6 is provided with a projection 9 to prevent removal. By inserting the anode-side charging contact piece 7 or 8 into the recessed step part 6 from the side of the part 6 over the protrusion 9, each charging contact piece 7.8 is inserted into the recessed step part 6, and the presence of the protrusion 9 is removed. This prevents the charging contacts 7 and 8 from coming off.

In FIG. 4, reference numeral 1 denotes a component mounting plate formed of a printed board, on which charging required components 12 such as rectifier diodes and current limiting resistors, and a charging indicator light 13.13 are attached. An engagement hole 14 is formed in the mounting plate 11, which is positioned so as to protrude upward, and the engagement hole 14 engages with the tip protrusion 16 of a spacer piece 15 protruding from the back surface of each holding plate 5. match.

For this reason, the mounting plate 11 is provided with a spacer piece 15 on the back side of the support body 4.
It will be installed with a gap between the two.

Some leads 17.17 of the component 12 are wound around and electromechanically coupled to protrusions 18.18 of the charging contacts 7, 8 protruding laterally of the support 4 (see FIG. 5). , support 4
and the mounting plate 11 are integrated into a unit.

By providing the mounting plate 11 separately from the support 4 in this way, it becomes easy to attach the necessary parts 12 to the mounting plate 1, and the leads 17 and 17 of the parts 12 can be connected to the charging connection attached to the support 4. By connecting the pieces 7, 8, an electrical connection of the charging contact and a mechanical connection of the mounting plate 11 and the support 4 can be effected.

A common cathode side contact piece 19 opposing the anode side charging contacts 7 and 8 is connected to this unit part via a lead, and a step-down transformer 20 and a power cord 21 are also connected, and the charging circuit components are connected to the main body case 1. Connected outside.

On the other hand, as shown in FIG. 5, the main body case 1 has a fitting opening 25 in which the upper end 24.24 of the retaining plate 5 fits in the vicinity of one 22 of the window 23.23 provided on the opposite surface of the recess 3.3. 25,
It has an engagement step part 27.27 with which the lower end engagement part 26.26 of the holding plate 5 engages, and also has a through-hole edge cylinder part 28.

Therefore, when the charging indicator light 13 is inserted into the cylindrical portion 28 and the upper end 24.24 of the retainer plate 5 is fitted into the fitting recess 25.25, the lower end engaging portion 26.26 of the retainer plate 5 engages with the engagement step. 27.27.

In this case, the support body 5 is temporarily fixed by friction between the lower end engaging portion 26 and the engaging stepped portion 27.

Next, as shown in FIG.
is fitted onto the lower protrusion 30 of the main body case 1, and the charging contact piece 19 is attached to the window 23, and the step-down transformer 20 is attached.

After that, by fixing the bottom cover 2 to the main body case 1, the protrusion 31 of the bottom cover 2 comes into contact with the lower end surface of the holding plate 5, and the protrusion 32 of the bottom cover 2 comes into contact with the lower surface of the charging contact piece 19. .

As described above, according to the configuration of the present invention, the charging contact and the charging circuit parts of the parts required for charging are assembled and connected in advance outside the main body case to form a unit, and the charger is assembled by attaching this unit part to the main body case. Therefore, the assembly time can be shortened and work efficiency can be improved compared to the case where required parts are attached to the main body case one by one.

Further, the component mounting plate mounted on the back surface of the support body is attached to the support body by fixing the lead of the component mounted on the mounting plate to the charging contact piece fixed to the front surface of the support body. The lead can simultaneously mechanically connect the support and electrically connect the charging contact,
Furthermore, since a charging indicator light that protrudes upward is attached to the mounting plate, the charging indicator light can be inserted into the hole edge tube of the charging case at the same time as the support body is attached to the main body case, making assembly easy and inexpensive. We can provide a charger.
