It is therefore necessary to make an electrical connection to connect the output taken from the battery to the circuitry of the radio receiver.

Conventionally, as shown in FIG. 4, a bent portion 2 is formed at the tip side of the battery terminal 1, the tip of the circuit board 3 is inserted into the bent portion 2, and the connection pattern 4 is inserted into the bent portion. 2 was electrically connected.

FIG. 5 shows another structure in which the circuit board 3
The stepped portion 6 of the boss formed at the upper end of the support column 5 that supports the
The bent part 2 of the battery terminal 1 is engaged with the part of the circuit board 3.
When the battery terminal 1 is fixed to the support column 5 with screws 7, the bent portion 2 of the battery terminal 1 is crimped to a connection pattern formed on the lower surface of the circuit board 3.

In yet another configuration, for example, as shown in FIG. 6, a notch 8 is formed in the side of the circuit board 3, and a jumper wire 9 is mounted on the circuit board 3 so as to cross this notch 8. The tip of the battery terminal 1 was brought into contact with the wire 9.

[0006]

[Problems to be Solved by the Invention] According to the connection structure shown in FIG. 4, force is required when inserting the circuit board 3 into the bent portion 2 of the battery terminal 1, and it is difficult to insert the circuit board 3 unless it is inserted directly from the side. Due to the problem of difficulty, it was not widely adopted.

The method shown in FIG. 5 has the disadvantage that the assembly requires many man-hours because the screws 7 are used to tighten and fix the parts. Further, it is necessary to form a stepped portion 6 on the support column 5 in advance.

The structure shown in FIG. 6 requires jumper wires 9 to be mounted in advance in the notches 8 of the circuit board 3.
This has the disadvantage that the structure of the circuit board 3 becomes complicated. Further, the connection between the battery terminal 1 and the jumper wire 9 is not necessarily achieved reliably, which poses a problem in reliability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 shows a clock radio receiver equipped with a connecting device according to an embodiment of the present invention, and this radio receiver is equipped with a cabinet 15. In FIG. The cabinet 15 is made of a synthetic resin molded body and has a substantially box-like shape. A pair of circuit boards 16 and 17 are arranged in the cabinet 15 so as to cross each other. One circuit board 16 constitutes, for example, a circuit of a radio receiver, and is mounted on support columns 18 and 19 that are integrally connected to the cabinet 15. Moreover, it is fixed to the support column 19 with screws 20. Note that various circuit components 21 are mounted on this circuit board 16.

A battery storage section 24 is formed on one side of the cabinet 15, and a dry battery 25 is stored in this battery storage section 24. The negative terminal of the dry battery 25 is crimped to a battery terminal 26. The battery terminal 26 is made of a wire made of conductive metal, and is connected to the cabinet 15 by the through hole 27.
The bent portion 28 formed at the tip of the circuit board 16 receives the tip of the circuit board 16 .

The second circuit board 17 is received by a post 31 formed in the cabinet 15, and
Its peripheral edge is locked by claws 32 and 33 integrally formed on the cabinet 15. Various circuit components 34 are mounted on the circuit board 17, and a switch 35 is also attached. The switch 35 includes an operating knob 36 and is exposed to the outside through an opening 37 in the cabinet 15.

Next, the electrical connection between the battery terminal 26 and the circuit board 16 will be explained with reference to FIGS. 1 and 2.

A first contact portion 41 and a second contact portion 42 are formed in the bent portion 28 of the battery terminal 26 so as to diagonally face each other. That is, the first contact portion 41 and the second
Dimension A of the diagonal gap of the contact portion 42 of the circuit board 16 is
The gap d is configured to have a larger value than the gap d. On the other hand, the dimension B of the gap in the height direction between the pair of abutting portions 41 and 42 is configured to be smaller than the thickness d of the circuit board 16.

Therefore, as shown in FIG. 1, the circuit board 16 is inserted obliquely between the first abutting part 41 and the second abutting part 42, where the gap A is wider than the thickness of the circuit board 16. do. At this time, since the gap A is larger than the thickness d of the circuit board 16, the circuit board 16 can be easily inserted. Then, as shown in FIG. 2, the circuit board 16 is rotated. Then, the contact part 41
, 42 in the height direction is smaller than the thickness d of the circuit board 16, the second contact portion 42 is crimped to the connection pattern 43 formed on the lower surface of the circuit board 16. Thus, by such crimping, it becomes possible to achieve reliable conduction between the battery terminal 26 and the connection pattern 43 of the circuit board 16.

As described above, in the connection device for the battery terminal 26 according to this embodiment, the first abutting part 41 and the second abutting part 42 are laterally shifted from each other on the bent part 28 of the battery terminal 26. After inserting the circuit board 16 obliquely, the circuit board 16 is rotated to a horizontal state, and the connection pattern 43 is crimped onto the battery terminal 26 to establish an electrical connection.

Therefore, the second abutting portion 4 of the circuit board 16 and the battery terminal 26 can be easily connected without applying force during assembly.
2, and the battery terminal 26 and the connection pattern 43 of the circuit board 16 come into stable contact.

Although the above embodiment relates to the connection between the battery terminal 26 and the connection pattern 43 of the circuit board 16, the present invention can be applied to various other terminal connection devices, such as antenna terminals and the like. It can also be applied to electrical connections with circuit boards.

It was designed so that

[0022]Therefore, there is no need to forcibly insert the circuit board between the pair of abutting portions, making assembly very easy. Moreover, by moving the circuit board, the gap between the pair of abutting parts becomes smaller than the thickness of the circuit board, so the connection pattern of the circuit board is crimped onto one of the abutting parts, ensuring a reliable electrical connection. This makes it possible to provide a highly reliable terminal connection device.
