It is related to the device.

[Conventional technology and issues to be solved]

BACKGROUND OF THE INVENTION Portable electronic devices have a built-in battery and are associated with a charging electrode terminal.

By the way, since fashion is important in cordless phones, design is prioritized, so many charging electrode terminals are made into complex shapes to fit the design, and when attached to a printed circuit board,
It is fixed to the printed circuit board using screws to withstand the impact of dropping. For this reason, there is a drawback that the number of work steps increases, which is unfavorable in terms of productivity.

This invention was made in view of the above-mentioned conventional circumstances, and its purpose is to provide an electrode terminal mounting device that allows the terminal itself to have a simple shape and that can be firmly mounted to a printed circuit board. There is a particular thing.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an electrode terminal mounting device that attaches an electrode terminal to a printed circuit board while sliding the electrode terminal. The terminal plate is made of a frame body, and a pair of terminal plates are arranged symmetrically at the front and rear of each individual plate, with openings oriented toward the front in the sliding direction, and each pair forming a pair. Each hook member is provided, and the edge of the printed circuit board is formed with a U-shaped notch into which the rear hook member is engaged, and the front hook member is engaged with a predetermined portion of the printed circuit board. Drill an engaging hole to
In addition, guide tapered surfaces for guiding the neck of the front hook member are formed in the engagement holes so that the side plates are parallel to each other.

In addition, the above object is to form an electrode terminal into a terminal plate consisting of a U-shaped frame including a pair of left and right side plates arranged almost parallel to each other, and a pair of engaging claws each having a head with an enlarged diameter in front of each side plate. and a pair of hook members with openings facing forward in the sliding direction, and a U-shaped hook member with the rear hook member engaged with the edge of the printed circuit board. In addition to forming a notch, an engagement hole into which the front engagement claw is engaged is formed in a predetermined part of the printed circuit board, and the hook member is engaged with the notch and slid. This can also be achieved by later fitting the engaging claw into the engaging hole and attaching the electrode terminal to the printed circuit board.

[For production]

According to the above configuration, the electrode terminal can be securely attached to the printed circuit board in a so-called one-touch operation. Moreover, the shape of the terminal itself is also relatively simplified.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, the electrode terminal IO includes a U-shaped frame 12 including a pair of left and right side plates 11, 11 extending parallel to each other. On the same side edge of each side plate 1.1.11, for example, on the upper edge side, there are two pairs of hook members 13, 13 that are approximately inverted L-shaped and open forward in the sliding direction indicated by arrow X.
; 14, 14 are provided symmetrically on the left and right, respectively.

In this case, the upper opening edge 13a of the front hook member 13 is provided with an appropriate slope to facilitate volatilization into the printed circuit board, which will be described later. Further, for convenience of the following explanation, the distance between the front hook member 13 and the rear hook member 14 is assumed to be A, the width of the front hook member 13 is assumed to be B, and the width of the neck portion 13b of the front hook member 13 is assumed to be C.

On the other hand, as shown in FIG. 2, the edge of the printed circuit board 20 is formed with a U-shaped notch 2l that is slightly wider than the width between the side plates 11, 11. ing. Further, an engagement hole 22 into which the front hook member l3 is engaged is formed at a position slightly smaller than the dimension A from the bottom side 21a of the notch portion 21. Inside this engagement hole 22, a front hook member 13 is inserted by narrowing the gap between the side plates 11, 11. 13
Step portions 22a, 22a for fitting into the engagement hole 22
, side sides 22b, 22b, which are arranged opposite to each other with a spacing approximately equal to the spacing in the free state of the side plates 11.11 and have a width C' slightly wider than the above-mentioned dimension C; and front hook member 13. 13 toward its sides 22b, 22b. Note that the guide tapered surface 22 extends from the base of the stepped portion 22a.
The straight line distance along the arrow X direction leading to c is the front hook member 13
It is substantially larger than the above-mentioned dimension B of .

To attach the electrode terminal 10 to the printed circuit board 20, first narrow the gap between the side plates 11, 11 and attach the front hook member 13.1.
3 along the inside of the step portions 22a, 22a, insert the engagement hole 2.
Fits inside 2. Thereafter, the electrode terminal IO is slid in the direction of arrow X. As a result, the front hook member 13. 1
3 is guided by the guide taber surfaces 22c, 22c, and its neck [3b] contacts the sides 22b, 22b of the engagement hole 22, and the rear hook member 14. 14 is notch part 2
1 (see Figure 3). The electrode terminal 10 is now temporarily attached to the printed circuit board 20, and the electrode terminal 10 and the printed circuit board 20 are soldered in the next step (not shown). Although not shown in detail, a solder land or the like is formed at the electrode terminal mounting portion of the printed circuit board 20.
Electrode terminal 10 is soldered there. In this way, the @pole terminal 10 is accurately positioned and securely attached to the printed circuit board 20. Another embodiment is shown in FIGS. 4-6. To explain the difference from the above embodiment, in this example, the front hook member 13. A pair of engaging claws 15.13 having heads 15a, 15a with an enlarged diameter. 1
5 is placed. Also, the rear hook member 14. 14
The upper opening edges 14a, 14a are provided with an appropriate slope to facilitate engagement with the edge 21a of the notch 2l.

On the other hand, the printed circuit board 20 has an engaging claw 15. l5
The engagement hole 25 corresponding to the engagement hole 25. 25 are drilled. In this case, the position of the hole is such that the upper opening edge 14a is located at the notch 2l.
This is the circumference of the engaging claw 15 when the engaging claw 15 is brought into contact with the edge 21a of the engaging claw 15.

To attach the electrode terminal 10 to the printed circuit board 20, first, attach the rear hook member 14. 14 into the notch 21,
The upper opening edges 14a, 14a are slid in the direction of arrow X.
is brought into contact with the edge 21a of the notch 21. Thereafter, the engaging claws 15, 15 are fitted into the engaging holes 25, 25. This temporarily fastens the electrode terminal 10 and the printed circuit board 20 as in the above embodiment.6 According to this, the electrode terminal 10 moves in the vertical, horizontal, and tensile directions. It can be firmly attached to the printed circuit board 20 without any problems.

〔Effect of the invention〕

As explained above, according to the present invention, the charging electrode terminal of a cordless telephone or the like can be attached to the printer 1/board by an extremely simple operation without using fasteners such as screws. Further, since the shape of the terminal itself is simplified, the mold thereof can also be made simple.
