Description
Technical Field
[0001] The utility model belongs to the field of mechanical keyboards, and in particular relates to a shaft seat terminal that can be stably clamped. Background Art
[0002] In existing mechanical keyboards, the shaft seat can realize hot-swappable shaft body. Users can freely replace mechanical keyboard shaft bodies with different feels from different manufacturers without turning off the power to improve the playability of the keyboard; however, for the existing shaft seat terminals, they are prone to deformation after repeated plugging and unplugging, which causes the clamping force to decrease and affects the stability of the connection between the shaft body and the shaft seat.
[0003] For example, a prior patent disclosed a hot-swappable shaft seat and keyboard (application number 202320113120.7). The hot-swappable shaft seat is used to achieve a detachable electrical connection between the keyboard switch and the PCB board. It includes a base insulated from the PCB board, and hardware riveted to the base and electrically connected to the keyboard switch. The base is provided with a mounting portion, and the hardware is provided on the mounting portion. The top of the mounting portion is provided with a buffer chamfer. When the shaft body is repeatedly plugged in and out of the shaft seat, the hardware terminals on the shaft seat are prone to deformation, resulting in a decrease in clamping force, affecting the stability of the connection between the shaft body and the shaft seat. Utility Model Content
[0004] In order to solve the above problems, the purpose of the present invention is to provide a stably clamped shaft seat terminal, which can clamp the shaft seat more stably and can still maintain the stability of its clamping force after multiple plugging and unplugging, and has a longer service life.
[0005] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows.
[0006] A stably clampable shaft seat terminal comprises a base plate, a first clamping side wall, and a second clamping side wall, one end of the first clamping side wall and one end of the second clamping side wall are respectively fixed on both sides of the base plate, the other end of the first clamping side wall is bent and extended toward the second clamping side wall to form a first clamping force arm, the other end of the second clamping side wall is bent and extended toward the first clamping side wall to form a second clamping force arm, and the first clamping force arm and the second clamping force arm form a plug-in gap; it is characterized in that the first clamping side wall is fixed with a first elastic supporting member, the first elastic supporting member corresponds to the side of the first clamping force arm away from the plug-in gap, and the second clamping side wall is fixed with a second elastic supporting member, the second elastic supporting member corresponds to the side of the second clamping force arm away from the plug-in gap.
[0007] In this shaft seat terminal, when the external shaft body is plugged into the shaft seat, the shaft body is inserted into the plug-in gap and squeezes the first clamping force arm and the second clamping force arm, causing the two to deform in the direction away from the plug-in gap. At this time, the first elastic abutment and the second elastic abutment respectively abut the side of the first clamping force arm away from the plug-in gap and the side of the second clamping force arm away from the plug-in gap, so as to assist the first clamping force arm and the second clamping force arm in clamping the shaft seat, thereby increasing the clamping force of the plug-in gap on the shaft seat and clamping the shaft seat more stably. Based on the abutment of the first elastic abutment and the second elastic abutment, the first clamping force arm and the second clamping force arm can be prevented from deforming too much and being unable to rebound after the shaft seat is plugged in and out multiple times, so that the terminal can still maintain the stability of its clamping force after multiple plugging and unplugging, and has a longer service life.

[0009] Furthermore, an insertion opening is formed between one end of the first clamping arm close to the first clamping side wall and one end of the second clamping arm close to the second clamping side wall, and the insertion and extraction gap is formed between the other end of the first clamping arm away from the first clamping side wall and the other end of the second clamping arm away from the second clamping side wall;
[0010] The other end of the first clamping force arm away from the first clamping side wall is bent in a direction away from the plugging and unplugging gap to form a first pulling-out portion, and the other end of the second clamping force arm away from the second clamping side wall is bent in a direction away from the plugging and unplugging gap to form a second pulling-out portion. An extraction opening is formed between the first pulling-out portion and the second pulling-out portion, and the widths of the insertion opening and the extraction opening are both smaller than the plugging and unplugging gap.
[0011] Furthermore, the width of the insertion port is 0.35-0.45MM.
[0012] Furthermore, the lengths of the first clamping arm and the second clamping arm are 0.65-0.75MM.
[0013] Furthermore, the first elastic supporting member and the second elastic supporting member are both "S"-shaped as a whole.
[0014] Furthermore, the shaft seat terminal also includes a first fixed side wall and a second fixed side wall, and the first fixed side wall and the second fixed side wall are respectively fixed on both sides of the base plate, and a first clamping protrusion is provided on the side of the first fixed side wall away from the second fixed side wall, and a second clamping protrusion is provided on the side of the second fixed side wall away from the first fixed side wall.
[0015] Furthermore, the shaft seat terminal also includes a third fixed side wall, which is fixedly arranged on one end of the bottom plate, and a third clamping protrusion is arranged on the third fixed side wall.
[0016] Furthermore, the shaft seat terminal also includes a first solder side wall and a second solder side wall, one end of the first solder side wall and one end of the second solder side wall are respectively fixed on both sides of the base plate, the other end of the first solder side wall is bent toward the second solder side wall to form a first solder portion, and the other end of the second solder side wall is bent toward the first solder side wall to form a second solder portion, and a creepage gap is formed between the first solder portion and the second solder portion.
[0017] Furthermore, the first solder side wall and the first clamping side wall are respectively fixed to both sides of the first fixed side wall, and the second solder side wall and the second clamping side wall are respectively fixed to both sides of the second fixed side wall.
[0018] The beneficial effect of the present invention is that in the shaft seat terminal, when the external shaft body is plugged into the shaft seat, the shaft body is inserted into the plug-in gap and squeezes the first clamping force arm and the second clamping force arm, so that the two are deformed in the direction away from the plug-in gap. At this time, the first elastic abutment and the second elastic abutment respectively abut on the side of the first clamping force arm away from the plug-in gap and the side of the second clamping force arm away from the plug-in gap, so as to assist the first clamping force arm and the second clamping force arm in clamping the shaft seat, thereby increasing the clamping force of the plug-in gap on the shaft seat and clamping the shaft seat more stably. Moreover, based on the abutment of the first elastic abutment and the second elastic abutment, it is possible to avoid the first clamping force arm and the second clamping force arm from deforming too much and being unable to rebound after the shaft seat is plugged in and out multiple times, so that the terminal can still maintain the stability of its clamping force after multiple plugging and unplugging, and has a longer service life.
