The two sides of the middle part of the contact bridge limiting cavity 14 are provided with limiting windows 30 for accommodating the protruding left and right sides of the contact bridge 11, and the contact bridge 11 arranged in the contact bridge limiting cavity 14 can only move in the vertical direction within a certain range in the limiting windows 30, so that the middle part of the contact bridge 11 can be pushed to the top of the limiting windows 30 through springs.
Further, the normally open contact blades 31 are arranged at two sides of the contact bridge limiting cavity 14, the tops of the normally open contact blades 31 extend to the lower part of the moving contact 15 of the contact bridge 11 at the corresponding side, and normally open static contacts 32 are arranged, and two ends of the spring 13 are fixed between the tops of the contact bridge limiting cavity 14 and the middle part of the contact bridge 11. If the normally open contact blade 31 is to be installed, the spring 13 needs to be put into the limit window 30 in the middle of the contact bridge limit cavity 14 from the contact bridge limit cavity 14 with the bottom opening, and then the contact bridge 11 is penetrated by standing on the side through the vertical through hole 29.
Further, the contact blade base 45 includes a vertical insulating fixing baffle 38 vertically disposed at the top, for separating the contact blades 12 at two sides of the cavity of the contact bridge spacing 14 along two sides of the vertical insulating fixing baffle 38, where the vertical insulating fixing baffle 38 and the bending section insulating fixing baffle 33 form a clamping spacing of the folding section 26. The left and right sides of the bottom of the contact blade base 45 are provided with transverse insulating fixed baffles 39 outwards for separating the bottom of the contact blade 12 along the transverse insulating fixed baffles 39.
As shown in fig. 11-12, specifically, when the normally closed contact blade 25 is selected, the normally closed fixed contact 27 of the normally closed contact blade 25 is located at the top of the moving contact 15 of the contact bridge 11, and the normally closed fixed contact 27 is kept in contact with the fixed contact by the spring 13 between the middle part of the contact bridge 11 and the contact bridge limiting cavity 14, so that a passage connection is formed between the normally closed contact blades 25. At this time, the top of the latch hook 20 is at the bottom of the heart-shaped chute track 22, and is in an unlocked state. When the light guide button piece 1 is pressed for the first time, the push rod base 4 drives the contact bridge 11 and the self-locking base 19 to move downwards, at the moment, the normally closed fixed contact 27 is separated from the moving contact 15, and the connection between the normally closed contact blades 25 is disconnected. When the resilience characteristic of the rubber sealing sleeve 40 can push the push rod base 4 to drive the contact bridge 11 and the self-locking base 19 to reset upwards, the top of the lock hook 20 falls back to the middle locking position from the top of the heart-shaped chute track 22, the push rod base 4 is locked and cannot reset, and the disconnection state between the normally closed contact blades 25 is in a locking state. When the light guide button piece 1 is pressed for the second time, the push rod base 4 drives the contact bridge 11 and the self-locking base 19 to enable the top of the lock hook 20 to return to the bottom of the heart-shaped chute track 22 from the locking position at the top of the heart-shaped chute track 22, so that the locking is released, at the moment, the elasticity of the rubber sealing sleeve 40 enables the light guide button piece 1 and the push rod base 4 to reset, the spring 13 pushes the contact bridge 11 to reset upwards, the movable contact 15 of the contact bridge 11 and the normally closed static contact 27 are enabled to restore to the contact state, and at the moment, the normally closed contact piece 25 is enabled to restore to the communicating state.
Further, when the normally open contact piece 31 is selected, the normally open static contact 32 of the normally open contact piece 31 is located below the moving contact 15 of the contact bridge 11, and the spring 13 between the middle part of the contact bridge 11 and the top of the contact bridge limiting cavity 14 pushes the contact bridge 11 towards the bottom of the limiting window 30 of the contact bridge limiting cavity 14, but still has a distance from the normally closed static contact 27, so that the normally closed static contact 27 keeps separated from the static contact, and a short circuit is formed between the normally closed contact pieces 25. At this time, the top of the latch hook 20 is at the bottom initial position of the heart-shaped chute rail 22, i.e. the unlocked state. When the light guide button piece 1 is pressed for the first time, the push rod base 4 drives the contact bridge 11 and the self-locking base 19 to move downwards, at the moment, the normally closed fixed contact 27 is contacted with the moving contact 15 under the pushing of the spring 13, and the normally closed contact blades 25 form a passage connection. When the elastic force of the rubber sealing sleeve 40 pushes the push rod base 4 to drive the contact bridge 11 and the self-locking base 19 to reset upwards, the top of the lock hook 20 falls back to the middle locking position from the top of the heart-shaped chute track 22, so that the push rod base 4 is locked and cannot reset, and the movable contact 15 of the contact bridge 11 is continuously in a locked connection state with the normally open contact piece 31 due to the thrust of the spring 13. When the light guide button piece 1 is pressed for the second time, the push rod base 4 drives the contact bridge 11 and the self-locking base 19 to move downwards, so that the top of the lock hook 20 returns to the initial position at the bottom of the peach heart-shaped slide groove track 22 from the locking position at the top of the peach heart-shaped slide groove track 22, at this time, the elasticity of the rubber sealing sleeve 40 enables the light guide button piece 1 and the push rod base 4 to reset, and the spring 13 pushes the contact bridge 11 to reset upwards, so that the movable contact 15 and the normally open static contact 32 of the contact bridge 11 are restored to the separated disconnection state.
The invention uses a contact device capable of freely replacing a normally-closed or normally-open contact blade 31 and a self-locking device with a heart-shaped chute track 22, and the top of the lock hook 20 is positioned at different positions of the heart-shaped chute track 22, so that the push rod base 4 is locked at the position after being pressed by the light guide button piece 1, and meanwhile, the normally-open fixed contact 32 or the normally-closed fixed contact 27 of the contact blade 12 is locked with or disconnected from the movable contact 15. Since the button product is usually a light source device, and includes a light source body 43 disposed on the contact blade base 45 and a light source wire leg 44 fixed on the contact blade base 45, the light source body 43 is electrically connected with the light source wire leg 44, and provides a power supply guarantee for indication of the light source body 43. And then the light source wire leg electricity 44 is electrically connected with the adjacent contact blades, so that when the button switch is closed and locked or the button switch is opened and locked, the light source body 43 is switched on or off while the control equipment is operated, and the light source body 43 is preferably a light emitting diode or an LED lamp.
Furthermore, the sliding rail locking device is made into an embedded part by utilizing a limited space, so that the contact device and the self-locking device are arranged at two sides of the push rod base 4 in the inner sleeve, a light guide area (not shown) capable of upwards transmitting light to the upper part of the light guide button piece 1 is formed in the push rod base 4, the push rod base 4 and the light guide button piece 1 can be made of materials with high light guide rate (such as acrylic or PC plates), and a light source transmits the light to the light guide button piece 1 through the push rod base 4 in the light guide area, so that the luminous indication function is realized. The sliding rail locking device is made into an embedded part by utilizing a limited space, so that the light guide rate and the wear-resistant material are perfectly compatible, and meanwhile, the button self-locking mechanism can be freely switched to be in a normally open or normally closed mode by replacing the normally closed contact blade group and the normally open contact blade group at the later stage according to requirements, thereby reducing the later use cost and facilitating the use.
