CN203812769U - Mechanical keyboard switch with novel movable terminal - Google Patents

Abstract

The utility model discloses a mechanical keyboard switch with a novel movable terminal. The mechanical keyboard switch comprises a switch main body, a groove on the top of the switch main body, a press shaft arranged in the groove, and two movable terminals symmetrically arranged in an inner cavity of the switch main body. The characteristics of the mechanical keyboard switch are that: a convex rib is arranged on the upper end of a foot part of each movable terminal; and the middle part and the lower part of the foot part of each movable terminal possess folding structures which is an S-shaped folding three-layer structure, or is formed by two connected S-shaped folding three-layer structure, or is a folding three-layer structure winding from inner to outer. The mechanical strength of the movable terminals is increased, the cold solder joint and false solder joint are reduced, and contact failure phenomenon caused by soldering flux, rosin and the like entering into the contact surface inside the switch can be prevented also.

Description

A kind of mechanical keyboard switch with Novel movable terminal

Technical field

The utility model relates to a kind of keyboard switch, especially a kind of mechanical keyboard switch with Novel movable terminal.

Background technology

The basic structure of conventional mechanical keyboard switch product as shown in Figure 1, it comprises switch main body 1, groove 2, by moved end 4 in axle 3 and switch main body 1, its foot's mid portion has been rushed a convex tendon bloating to 4 of moved end as shown in Figure 2, and the inner face of this convex tendon is a groove.Because moved end 4 need to carry out soldering in assembling process Zhong Qi foot, this groove is easily hidden the bad materials of conduction such as scaling powder or rosin, and cause the upper tin area of welding to reduce, thereby caused the weld strength decline of client's soldering process and the defect that forms rosin joint and dry joint.Simultaneously because the effect of this convex tendon causes inserting, wear plastic cement position and have gap, easily make scaling powder or rosin etc. run into the contact surface to switch inside and then contact inefficacy.Another defect is that son 4 material in moved end are thick thinner, although beat convex tendon type structure, can improve terminal intensity to a certain extent, can not stop completely, thereby affect useful life and the quality of keyboard switch product.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of mechanical keyboard switch with Novel movable terminal, the mechanical strength of its moved end increases, and can reduce rosin joint dry joint phenomenon, and can avoid the foreign material such as scaling powder or rosin to enter the contact surface of switch inside and cause contacting failure phenomenon.

The technical solution of the utility model is: a kind of mechanical keyboard switch with Novel movable terminal, comprise switch main body, switch main body top groove, be located in groove by axle and be symmetricly set on two moved end in switch main body inner chamber, it is characterized in that: the foot upper end of described moved end is provided with convex tendon, in the middle of the foot of moved end and the cross section of lower end has accordion structure.

Described accordion structure is the collapsible three-decker of S shape or is formed by connecting or collapsible three-decker for reeling from inside to outside by two collapsible three-deckers of symmetrically arranged S shape.

Square LED is installed, to use in described switch main body under the environment of insufficient light.

The beneficial effects of the utility model are:

1, the mechanical strength of terminal increases: the pin position tablet thickening of moved end, in assembling process, increase the intensity of terminal supportor position, reduced the distortion of terminal in contact pin process and welding process, be conducive to realize automated production, due to the increase of terminal intensity, reduced the infringement because of factors such as transportation, assemblings, product being caused in circulation process simultaneously;

2, because terminal supportor position folds covering several times, reduced convex-concave space, just avoided scaling powder or rosin etc. material hide into the impact that wherein forms drum, therefore can allow it really play the lifting for welding quality, thereby further reduced the defects such as rosin joint and dry joint;

3, by the folding covering of moving terminal supportor position, not only increased surface area, after being inserted into plastic parts, also accordingly the terminal needle inserting hole of switch is filled up, can effectively reduce because scaling powder or rosin etc. runs the contact failure phenomenon causing into the contact surface to switch inside simultaneously.
