Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a movable contact mounting structure of a push button switch. Background Art

[0002] Push button switches and other switch-type electrical components operate by moving the movable contact to close and separate. After the movable contact is closed, a return spring drives the movable contact back to its initial position. When installing the movable contact into the housing of existing push button switches, the spring must first be depressed to make room for the movable contact. However, the existing housing is sealed at both ends, requiring a specialized tool to depress the return spring. The movable contact is then installed into the housing, and the return spring is then released, allowing it to return to its original length to support the movable contact. This installation and assembly method presents certain limitations and difficulties, requiring specialized installation tools and processes. Installation and removal are time-consuming, labor-intensive, and inconvenient. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0016] like Figures 1 to 3 FIG. 1 shows a preferred embodiment of a push button switch movable contact mounting structure, comprising:

[0017] The shell 1, the moving contact body 2 and the spring 3, the shell 1 has a channel portion 4, the upper end of the shell 1 is provided with a mounting hole 5, the mounting hole 5 is connected with the upper end of the channel portion 4, the spring 3 is installed in the channel portion 4, the two surfaces of the shell 1 are provided with an opening 6, the two openings 6 are connected with the channel portion 4, the inner walls on both sides of each opening 6 are formed with two limit blocks 7 in a direction approaching each other, and there is a gap between the two limit blocks 7, the moving contact body 2 is slidably installed in the channel portion 4, the moving contact body 2 can be operably moved along the length direction of the channel portion 4, the moving contact body 2 is arranged above the spring 3, the two ends of the moving contact body 2 extend out of the two openings 6, and the moving contact body 2 can be operably clamped against the lower end of the four limit blocks 7.

[0018] During actual use, first place the spring 3 in the channel portion 4 through the mounting hole 5, then pass one end of the moving contact body 2 through an opening 6, the channel portion 4 and the other opening 6 in sequence, and set the moving contact body 2 above the spring 3, then rotate the moving contact body 2 ninety degrees, and press the upper end of the spring 3 downward until the moving contact body 2 completely passes through the gap between the two adjacent limit blocks 7, then rotate the moving contact body 2 in the opposite direction, release the moving contact body 2, and the spring 3 extends, so that the moving contact body 2 is stuck against the lower end of the limit block 7.

[0019] Furthermore, as a preferred embodiment, the moving contact body 2 includes: a touch plate 8 and two contacts 9, the touch plate 8 is slidably installed in the channel portion 4, the two ends of the touch plate 8 extend out of the two openings 6, and the two contacts 9 are installed at the two ends of one surface of the touch plate 8.

[0020] Furthermore, as a preferred embodiment, two grooves are formed on both sides of the touch panel 8, and the width of the two grooves is greater than the width of the housing 1. Furthermore, by forming grooves on both sides of the touch panel 8, the touch panel 8 is prevented from shaking in the channel, ensuring the stability of the touch panel 8 when moving.

[0021] Furthermore, as a preferred embodiment, a protrusion 10 is provided in the middle of one surface of the touch panel 8, and the protrusion 10 is operable to extend into the upper end of the spring 3. Furthermore, by providing the protrusion 10 and allowing the protrusion 10 to extend into the upper end of the spring 3, the stability of the touch panel 8 when pressing the spring 3 is ensured.

[0022] Furthermore, as a preferred embodiment, the outer contour of the protruding block 10 is arranged in an arc shape. Furthermore, the outer contour of the protruding block 10 is arranged in an arc shape, which facilitates the protruding block 10 to extend into or out of the spring 3, thereby improving installation efficiency.

[0023] Furthermore, as a preferred embodiment, the height of the upper surfaces of two adjacent limit blocks 7 gradually decreases as they approach each other. Furthermore, the height of the upper surfaces of the limit blocks 7 gradually decreases, i.e., the upper surfaces of the limit blocks 7 are inclined, thereby guiding the touch panel 8 and facilitating its passage through the gap.

[0024] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
