[0028] Please refer to Figures 1 to 7, an open plug-in device, comprising a first device 1, a second device 2, a fastener 3 and a circuit switch 4 for controlling the open plug-in and power-on and power-off of the first device 1. The first device 1 and the second device 2 can be open plugged in to realize data transmission; the circuit switch 4 is arranged on the first device 1; the fastener 3 cooperates with the first device 1 and the second device 2 to lock the second device 2 and plug it into the first device 1 or release the above-mentioned lock. When locked, it is in a plugged-in state to realize data transmission, and when released, it is in an unplugged state. The fastener 3 and the circuit switch 4 cooperate with each other and the circuit switch 4 is in a powered-on state when locked, and in a powered-off state when released. Then, the circuit switch 4 on the first device 1 is disconnected when released, and the second device 2 is unplugged after the lock is released, so as to effectively protect the OPS module and avoid damage to the OPS module during hot plugging.

[0029] The circuit switch 4 comprises a circuit board 41, a first bracket 42, a second bracket 43, and a movable member 44, disposed within the first device 1. The first bracket 42 and the second bracket 43 are electrically connected to two electrical terminals of the circuit board 41, respectively, and are both fixedly attached to the circuit board 41 of the first device 1. The movable member 44 is movable relative to and electrically connected to the second bracket 43, and is capable of moving toward or away from the first bracket 42. The fastener 3 and the movable member 44 cooperate to drive the movement of the movable member 44, which is controlled by the movement of the movable member 44 to connect or disconnect the movable member 44 from the first bracket 43, thereby controlling the powering on and off of the circuit switch 4.

[0030] The first bracket 42 is provided with a first captive screw 45, the second bracket 43 is provided with a second captive screw 46, the movable part 44 is the sliding part of the second captive screw 46, and the fastener 3 includes a mounting screw, which can push against the sliding part of the second captive screw 46, and the mounting screw can be spirally rotated to push against the movement of the sliding part.

[0031] The first captive screw 45 and the second captive screw 46 have the same structure and include a fixing portion 47 , a sliding portion 48 that can slide relative to the fixing portion 47 , and a spring 49 that presses between the fixing portion and the sliding portion. The cam 482 is fixed to the base 481 and is secured to the rear of the second support 42. The cam 483 is secured to the rear of the second support 42.

[0032] The first device 1 is a microcomputer, the second device 2 includes a display screen, the first device 1 has a first fixing frame 11, the second device 2 has a second fixing frame 21, the mounting screw connects the first fixing frame 11 and the second fixing frame 12 to lock the first fixing frame and the second fixing frame; the fastener 3, the second bracket 43 and the first bracket 42 are arranged back to front along the mounting screw threading axis, and the mounting screw threading axis is arranged front to back.

[0033] When the open plug-in / plug-out device is in the plug-in / plug-out state, the fastener 3 abuts the movable member 44, extending it and causing the front end of the movable member 44 to contact and abut the second captive screw. This electrically connects the first bracket 42 to the second bracket 43, and to the two electrical terminals of the circuit board 41, thereby energizing the circuit switch 4. Before removing the second device 2, the fastener 3 must be withdrawn. As the fastener 3 is withdrawn, the spring 49 forces the movable member 44 back to its initial state, disconnecting the movable member 44 from the second captive screw. This disconnects the electrical connection between the first bracket and the second bracket, de-energizing the circuit switch and the first device. After the fastener is withdrawn, the second device is removed. Since the first device is powered off before the second device is removed, the OPS is effectively protected. The fastener 3 pushes forward, extending the second captive screw, and the movable member extends forward to contact the sliding portion of the first captive screw, energizing the circuit switch. Both the captive screw and the bracket are electrically conductive, such as being made of nickel-plated metal.

[0034] In this specific embodiment: the second end surface of the base of the second captive screw 46 is recessed with a matching groove, and the front end of the fastener 3 can be inserted into the matching groove and can push the movable part forward by pressing against the bottom of the matching groove.

[0035] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
