Production of key bridge

Abstract

The invention is concerned with the manufacture method of key bridging, which is the bridging structure that can provide the stable relative rotation and limited key travel and connect between the key cap and the bottom board, the steps are: takes out the bridge inner frame, the bridge outer frame and the infusing bar that shapes by the die, makes the right position of the combining part of the bridge inner frame and the bridge outer frame, the tool bring a force to the inner frame in order to combination and cut of the two parts, namely complete the bridge finished product, combines several bridge inner and outer frame on the infusing bar quickly, separates from the infusing bar in order to reduce the time and process for combine the key bridge, and avoid the waste of manpower and man-hour.

Description

technical field [0001] The invention relates to a manufacturing method of a key bridging bridge, in particular to a manufacturing method of a bridging structure applied between a key cap and a bottom plate, which can provide reliable relative rotation and limit the stroke of a key. Background technique [0002] The key structure currently applied to thin keyboards mainly includes a keycap, a bridge (or called a scissor-type linkage structure), a circuit board, a touch element, and a bottom plate (the bridge is also manufactured on a bridge plate) , and then set the circuit board between the bridge plate and the bottom plate), and the bridging mechanism technology can be divided into two major items, which are described as follows: [0003] 1. As described in U.S. Patent Nos. 5,278,374, 5,555,971, 5,964,341, and 6,428,223, the side brackets of the inner frame and the outer frame are provided with a shaft portion and a shaft rotation portion, but the disadvantage is that the i...

Problems solved by technology

[0005] As far as assembling the inner and outer frames of the bridge structure of the keyboard keys is concerned, in the prior art, the inner and outer frames of each bridge must be cut from the injection rod and then assembled one by one, and the alignment work is quite difficult The inner and outer frame parts are usually made of plastic injection molding and mass-produced, thereby reducing the manufacturing cost. In addition, after the injection molding of the inner and outer frames is completed, the inner and outer frames are first disassembled from the injection rod formed by the runner. Then, they are assembled separately, which takes a lot of man-hours, and the manufacturing cost is relatively increased.
