Abstract

(57) [Abstract] [Object] The present invention relates to an electrical connection device for connecting an electrode wire, one end of which is connected to a battery, to a printed wiring board of a transmitter body in a remote control transmitter or the like. The land portion of the wiring board and the electrode wire are connected very easily. [Structure] The present invention includes a coiled portion 14 at the end of the electrode wire 14.
When the upper case 11 and the lower case 15 are integrated with the land portion 13 of the printed wiring board 12, the coil-shaped portion 14a is pressure-contacted to the electrode portion 14 and the land portion 13 without soldering. It is to be electrically connected.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electrical connection device for connecting a remote control transmitter (hereinafter, referred to as a remote controller) or the like with a printed wiring board of a remote controller body and the other end of an electrode wire having one end connected to a battery.

[0002]

[Prior art]

 A conventional technique will be described with reference to FIG. This figure shows the main part of the connection part with the printed wiring board 1 of the remote control main body and the electrode wire 2 which is the connection part (not shown) to the battery on the one side. According to the figure, 4 is the printed wiring board. Reference numeral 5 denotes a hole provided in the plate 1, and reference numeral 5 denotes a land portion for soldering provided around the hole 4 connected to the electrode wire 2 provided in the printed wiring board 1. Reference numeral 3 denotes a U-shaped portion of the electrode wire 2, which is inserted into the hole 4 to position the electrode wire 2. Reference numeral 6 is a solder for connecting the electrode wire 2 to the land portion 5 in the land portion 5.

[0003]

[Problems to be solved by the device]

 However, in the conventional connection between the electrode wire 2 and the printed wiring board 1, the U-shaped portion 3 of the electrode wire 2 needs to be manually inserted into the hole 4 of the printed wiring board 1 and manually soldered, which requires a lot of assembly work. There was a problem that it took a lot.

The present invention solves the above problems and provides an electrical connection device that can be assembled by an automatic machine.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention forms one end of an electrode wire into a coil shape and, at the same time, clamps this coiled part to a land part of a printed wiring board by a device case. To connect.

[0006]

[Action]

 As described above, according to the present invention, one end of the electrode wire is formed in a coil shape, and the coiled portion is clamped to the land portion of the printed wiring board by the case of the device for pressure contact, so that it is easy to use without soldering. It can be automatically assembled by assembling at the same time.

[0007]

【Example】

 The electrical connecting device of the present invention will be described with reference to the remote controller shown in FIGS.

According to the figure, 12 is a printed wiring board, 13 is a land portion, and the upper portion thereof is used for automatic soldering when another component (not shown) is mounted on the printed wiring board 12. Therefore, the solder 13a is filled. One of the electrode wires 14 is a connecting portion (not shown) to the battery, and the coiled portion 14a is formed on the other end side. Reference numeral 15 is a lower case of the remote control, and a rib-shaped projection 16 is provided at a position corresponding to the land portion 13. Reference numeral 18 denotes a protrusion integrally provided on the upper case 11 for positioning the electrode wire 14 in the groove portion 18a.

Reference numeral 17 is a rib-shaped protrusion provided on the upper case 11 and having a convex portion 17 a in the center. When the upper case 11 and the lower case 15 are engaged and integrated by a known means, the convex portion 17a of the rib-shaped projection 17 is inserted into the center of the coil-shaped portion 14a of the electrode wire 14, and the coil-shaped portion 14a is positioned so as to be sandwiched and pressure-contacted to the solder 13a on the land portion 13, and the wing portion of the rib-shaped projection 17 is formed larger than the diameter of the coil-shaped portion 14a, and When the lower case 15 is integrated, this coil-shaped portion 14a is used as a means for press-contacting the solder 13a.

[0010]

[Effect of device]

 In the present invention, as is apparent from the above-mentioned embodiment, the ends of the battery electrode wires are formed in a coil shape, and when the upper and lower cases of devices such as remote controllers are integrated, this coiled part is formed on the land part of the printed wiring board. Since electrical connection is made by sandwiching and pressing, it is possible to reduce the assembly work such as soldering work and to enable automatic assembly.
