Abstract
A push-button switch with a plastic plug comprises a shell. A button which can slide upwards and downwards is inserted in the shell; the head of the button is exposed; a spring base is arranged below the button; the lower end of the button props against the spring base; the spring base is internally provided with a compression spring; an elastic sheet is arranged in the shell below the compression spring; the elastic sheet is provided with a movable contact; a fixed contact corresponding to the movable contact is arranged below the movable contact; the lower end of the compression spring is plugged by the plastic plug; the plastic plug comprises a piston and a head; and the piston is plugged in the compression spring and the head is arranged below the compression spring. As the lower end of the compression spring is plugged by the plastic plug, the plastic plug used as an insulated part can isolate the elastic sheet from other parts.
Description
(1) technical field
The utility model relates to a kind of push-button switch with plastic cement plug.
(2) background technology
Push-button switch generally comprises housing, is inserted with the button that can slide up and down in the housing, and the head of button exposes; There is spring base the below of button, and the lower end of button is supported and is located on the spring base; Be provided with stage clip in the spring base, be provided with shell fragment in the housing of the below of stage clip, shell fragment is provided with moving contact; The below of moving contact is provided with the fixed contact corresponding with it, presses the button, and conducting when two contacts are contacted disconnects when the contact separates.The shortcoming of existing this push-button switch is: as the shell fragment of conductive component and the touching of the button mechanism above it, cause short circuit easily when operation.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing push-button switch, the utility model provides a kind of shell fragment can realize the push-button switch with plastic cement plug of insulating mechanism.
The technical scheme in the invention for solving the technical problem is: a kind of push-button switch with plastic cement plug, comprise housing, and be inserted with the button that can slide up and down in the described housing, the head of described button exposes; There is spring base the below of described button, and the lower end of described button is supported and is located on the described spring base; Be provided with stage clip in the described spring base, be provided with shell fragment in the housing of the below of described stage clip, described shell fragment is provided with moving contact; The below of described moving contact is provided with the fixed contact corresponding with it; The following end plug of described stage clip is provided with the plastic cement plug, and described plastic cement plug comprises stick harness and head, and described stick harness plug is located in the described stage clip, and described head is positioned at the below of described stage clip.
Further, the head of described plastic cement plug is round pie, and the diameter of the head of the plastic cement plug of round pie is greater than the external diameter of described stage clip.
The beneficial effects of the utility model are: 1. owing to the following end plug at stage clip is provided with the plastic cement plug, the plastic cement plug can separate shell fragment and miscellaneous part as insulating element.2. the round pie head of plastic cement plug is smooth, and contact force is more stable when pushing shrapnel, and has reduced the eccentric force of stage clip simultaneously.3. the plastic cement plug has reduced shell fragment heating heat and has conducted to the motion part, has prolonged the life-span of mechanism.
(4) description of drawings
Fig. 1 is a sectional structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of stage clip part of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of push-button switch with plastic cement plug comprises housing 1, is inserted with the button 2 that can slide up and down in the described housing 1, and the head of described button 2 exposes; There is spring base 3 below of described button 2, and the lower end of described button 2 is supported and is located on the described spring base 3; Be provided with stage clip 4 in the described spring base 3, be provided with shell fragment 5 in the housing of the below of described stage clip 4, described shell fragment 5 is provided with moving contact 6; The below of described moving contact 6 is provided with the fixed contact corresponding with it 7; The following end plug of described stage clip 4 is provided with plastic cement plug 8, and described plastic cement plug 8 comprises stick harness 9 and head 10, and described stick harness 9 plugs are located in the described stage clip 4, and described head 10 is positioned at the below of described stage clip 4.In the present embodiment, the head 10 of described plastic cement plug 8 is round pie, and the diameter of the head of the plastic cement plug of round pie is greater than the external diameter of described stage clip 4.
The utility model is owing to the following end plug at stage clip 4 is provided with plastic cement plug 8, and plastic cement plug 8 can separate shell fragment 5 and miscellaneous part as insulating element.The round pie head of plastic cement plug 8 is smooth, and the 5 o'clock contact forces that push shrapnel are more stable, has reduced the eccentric force of stage clip 4 simultaneously.While plastic cement plug 8 has reduced shell fragment heating heat and has conducted to the motion part, has prolonged the life-span of mechanism.
Claims (2)
