Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of pointing stick, and more particularly, to a structure of a cursor pointing stick which is used in an analog signal generator of electronic and computer equipment to simplify components and facilitate assembly.

[0002]

[Prior art]

 Known cursor input devices are used in a wide variety of input devices, such as control panels, keyboards, remote control devices, or other similar electronic devices, such as mice, joysticks, touchpads, and tracks. Implemented as a ball, pointing stick, or other similar structure. Among them, the operation of the pointing stick is to generate an analog signal by the strain generated when the pointing stick receives a force in a predetermined direction, and to output this analog signal for use by computer equipment. is there. Please refer to FIG. 1 for an operation example. In FIG. 1, a cursor pointing stick 3 is attached between key switches of a keyboard 2 of a notebook computer 1 to detect a direction of an applied force of an operator, generate distortion, and move a cursor of the computer. Provide a signal.

FIGS. 2 and 3 are an exploded perspective view of a structure of a known pointing stick 3 and a longitudinal sectional view of a main body 30 of the pointing stick 3, respectively. As shown in these figures, the pointing stick 3 is mounted on the main body 30 and the upper end of the pointing stick 3 to fix the pointing stick 3 to the operation device, and is attached to the mounting seat 301 to form an annular shape. And a receiving body 305 having a housing through hole 306 in the middle, a holding means 303 for holding the receiving body 305 between the erection seats 301, and a column 307 mounted in the housing through hole 306 and receiving an external force. The column cover 32 and the cap 31 are installed on the upper end of the column 307. The installation seat 301 is provided with a through-hole (not shown) corresponding to the accommodation through-hole 306, and is used for passing through the column 307.

As shown in FIGS. 2 and 3, the column 307 is provided with a strain gauge 311 for generating an analog signal on each side thereof. The lead 313 is extended, and an analog signal generated by the strain of the strain gauge 311 is output from the two leads 313. A bus 309 having at least a pair of lead wires (not shown) is located at the bottom of the receiver 305, and the end of the lead wire is welded to the lower end of the lead 313 of each strain gauge 311 of the column 307. The other end of the lead wire is connected to one circuit board (not shown).

According to the structure of the well-known pointing stick 3 (FIGS. 1, 2, and 3), the joining method of the lead 313 and the lead wire of the bus 309 is achieved by the solder spot 100 formed by processing. In the coupling step, first, the end of the bus 309 is passed through the end of the column 307 (the lead wires at the end of the bus 309 are arranged radially and pass around the center of the column 307 in a ring shape). After that, each lead wire of the bus 309 is made to face the corresponding lead 313, and then soldering is performed between the lead 313 and the lead wire.

However, according to the above-described method of connecting the lead 313 and the lead wire, it is necessary to project a part of the end of the column 307 to the bottom of the receiving body 305 as an area where the solder spot 100 can be operated and adhered. However, this configuration is in electronic devices, especially notebook computers, and requires a lot of extra space to protrude, and thus does not meet the demand for lighter products.

Another disadvantage of the well-known pointing stick 3 is that, as an external combination part of the column 307, the mounting seat 301, the holding means 303, and the receiving body 305 are required to be connected. It is not easy to handle, and therefore, in assembling a well-known structure, the combination of the above-mentioned parts (especially the operation of clamping the receiving body 305 to the erection seat 301 by the clamping means 303) is performed by a specialized engineer. (Besides the operation of attaching the pointing stick to the operation device), so that the time required for the work is directly proportional to the total work amount, and there is a possibility that a processing error may occur. Indirectly affected the competitiveness in manufacturing efficiency and cost performance.

[0008]
