Embodiment

Please refer to shown in Figure 1ly, be the stereogram of the utility model one preferred embodiment, the electrical connection arrangement 1 of this computer input unit comprises:

One insulating base 10 has several grooves 11, and each groove 11 is distributed in distance;

Several conducting strips 20, each conducting strip 20 are that the one segmentation bends shaping and has a fitting portion 2

1, a contact site 22 and a pin portion 23, this fitting portion 21 slightly takes the shape of the letter U and is located at respectively in the groove 11 of insulating base 10, this contact site 22 is to extend upward the bending shaping from the upper end of fitting portion 21 and protrude in insulating base 10 tops, and this pin portion 23 is positioned at contact site 22 belows from fitting portion 21 lower ends to the extension of insulating base 10 the place aheads.

Please refer to shown in Figure 2, be applied to the three-dimensional exploded view of a computer input unit for the utility model, this computer input unit is example with the mouse, comprise a drain pan 30, a printed circuit board (PCB) module 40 and a upper casing 50, wherein, this drain pan 30 is formed with a location notch 31, and the insulating base 10 of the utility model electrical connection arrangement 1 can coincide and be arranged in this location notch 31, and this printed circuit board (PCB) module 40 is to should electrical connection arrangement 1 and be fixedly arranged on the drain pan 30.
