[0031] Embodiment 1

[0032] Reference Figures 1 to 6 As shown, the utility model provides an electromagnetic separation device, which is particularly suitable for reliable connection of electrical signals on the equipment rack and reliable separation before ignition, including a housing 2, a solenoid valve 1, and a plug 4. The housing 2 is provided with an external interface 6, the plug 4 is plugged with a socket 7, and a push-pull locking mechanism is provided between the plug and the socket. When the solenoid valve 1 is powered on, the plug is pulled away from the socket by a set distance, and the push-pull locking mechanism is unlocked, that is, the plug and the socket are unlocked and separated.

[0033] In order to prevent the plug from being unable to be completely retracted into the electromagnetic separation device after the plug and the socket are unlocked and separated. In this embodiment, the electromagnetic separation device also includes a recovery mechanism 5 installed on the housing 2, and the recovery mechanism 5 includes a telescopic sleeve assembly and a spring assembly. The telescopic sleeve assembly is connected to the solenoid valve 1 and the plug 4. When the telescopic sleeve assembly is extended, the solenoid valve 1 and the plug 4 move together; when the plug 4 moves toward the socket 7, the telescopic sleeve assembly extends and overcomes the elastic force of the spring assembly, so that the plug and the socket complete the plug-in action; after the push-pull locking mechanism is unlocked, driven by the spring assembly, the telescopic sleeve assembly drives the plug to achieve recovery.

[0034] Therefore, when the electromagnetic separation and unlocking is performed in advance before the equipment is launched, the solenoid valve is energized, pulling the plug to move a set distance away from the socket, and the push-pull locking mechanism is unlocked. After the plug is unlocked and separated from the socket, the plug can be completely retracted into the electromagnetic separation device under the action of the recovery mechanism.

[0035] Specifically, the telescopic sleeve assembly is connected to a slide plate 55, the solenoid valve 1 is mounted on the slide plate 55, and the plug 4 is connected to the solenoid valve 1. The housing 2 is provided with an operating port corresponding to the solenoid valve, so that when the solenoid valve is pressed through the operating port, the solenoid valve drives the slide plate and the plug to move toward the socket.

[0036] In this embodiment, the telescopic sleeve assembly includes a nested sleeve 1 56, a sleeve 2 57 and a sleeve 3 58, sleeve 3 is fixed to the housing, sleeve 1 is telescopic relative to sleeve 2, and sleeve 2 is telescopic relative to sleeve 3. The spring assembly includes a compression spring 1 51 connecting sleeve 1 and sleeve 2, and a compression spring 2 52 connecting sleeve 2 and sleeve 3. Sleeve 1 is connected to the slide plate by a fixing pin 53. In addition, the movement strokes of sleeve 1 and sleeve 2 are both ≥75mm, so that the total stroke of the telescopic sleeve assembly is ≥150mm. Therefore, the insertion stroke is large, up to 150mm, and the recovery time is short, and the device can be recovered within 500ms. In each telescopic sleeve assembly, three sleeves are installed in a stacked manner, which reduces the size of the entire mechanism while ensuring sufficient insertion stroke, thereby achieving the purpose of miniaturized design.

[0037] Specifically, the recovery mechanism 5 is provided with four telescopic sleeve assemblies and corresponding four spring assemblies located at the four corners of the rectangle, and the solenoid valve 1 is provided between the four telescopic sleeve assemblies, that is, the solenoid valve is provided in the middle position between the four telescopic sleeve assemblies. In this way, the plug insertion process and the recovery process can be ensured to remain stable, and sufficient recovery force can be provided to shorten the recovery time. A bracket 59 is provided between the solenoid valve 1 and the slide plate 55, and the bracket 59 includes a connecting sleeve fixed to the solenoid valve 1 and side connecting members provided on the left and right sides of the solenoid valve, and side wings are provided on the left and right sides of the connecting sleeve, the upper end of the side connecting member is connected to the side wing, and the lower end is provided with a fixing foot fixed to the slide plate. Therefore, the solenoid valve and the slide plate are reliably fixed.

[0038] Principle of electromagnetic separation device plugging and engaging: The electromagnetic separation device and the socket 7 are locked mainly by the push-pull locking mechanism between the plug 4 and the socket 7. The product is plugged and locked by direct insertion. In the initial state, the plug 4 is in place, the solenoid valve 1 is pressed, the plug 4 moves downward, the sleeve 1 56 and the sleeve 2 57 move downward, and the elastic force of the compression spring 1 51 and the compression spring 2 52 must be overcome during the movement, and the plug 4 and the socket 7 complete the plugging action. During the entire plugging process, the movement stroke of the sleeve 1 56 and the sleeve 2 57 are 75mm respectively.

[0039] Principle of electrical separation and unlocking: After passing 28V±3V voltage to the solenoid valve 1, the plug housing 41 is pulled upward by 3mm to realize the unlocking and separation of the plug and the socket. After unlocking, the plug 4 is recovered under the drive of the recovery mechanism 5, and the plug 4 is retracted into the electromagnetic separation device to complete the reset.

[0040] In addition, a mechanical unlocking backup method is reserved. Figure 6 As shown, the solenoid valve is provided with a pull rod 11, and the pull rod 11 is connected to a U-shaped adapter frame 50, and the two sides of the adapter frame movably pass through the slide plate and are connected to the plug through the adapter plate 54. The top edge of the adapter frame 50 is provided with a step hole, and the pull rod 11 is provided with a step head, and the step head cooperates with the step hole.

[0041] Mechanical separation and unlocking separation principle: During mechanical separation, an external force is applied to the plug jacket 41, and after the plug jacket 41 is pulled to move 3mm, the plug and the socket are unlocked and separated. Since the action process during electrical unlocking is that the step head at the pull rod 11 drives the step hole on the adapter frame, during mechanical separation, the adapter frame 50 moves upward under manual action to directly unlock without interfering with the solenoid valve. The subsequent reset process is consistent with electrical separation and will not be repeated. Therefore, in the event of failure of electromagnetic unlocking, the unlocking action can be completed mechanically, so the unlocking reliability is high.

[0042] For details, reference may be made to the prior art. The push-pull locking mechanism includes a groove provided on the plug housing and a steel ball provided on the socket. When the plug and the socket are plugged into place, the steel ball enters the groove to complete the locking action.

[0043] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0044] a) The utility model is easy to operate, and the plugging and closing action can be completed by direct plugging, without complicated and redundant actions.

[0045] b) The utility model has a large insertion stroke, which can reach 150mm, and a short recovery time, and the device recovery can be completed within 500ms.

[0046] c) The electromagnetic separation device of the utility model has high safety. It can be unlocked and recovered in advance before the equipment is launched, effectively preventing interference with the main body movement.

[0047] d) The utility model has high unlocking reliability and reserves a mechanical unlocking backup method. In the event that the electromagnetic unlocking fails, the unlocking action can be completed mechanically.

[0048] Embodiment 2

[0049] In this embodiment, the electromagnetic separation device also has a signal feedback function. A travel micro switch 3 is designed inside the electromagnetic separation device. When the plug and the socket are locked, the micro switch is in the on state, and when the plug and the socket are unlocked and separated, the micro switch is in the off state.

[0050] Specifically, the lead-out cable of the solenoid valve 1 pin and the micro switch 3 terminal is connected to the socket 4, so as to realize the transmission of the input signal of the solenoid valve 1 and the feedback signal of the micro switch 3. The travel micro switch 3 is installed on the sleeve 3 58, and corresponds to the position when the bracket is reset, and the micro switch is triggered by the bracket. Therefore, it is possible to judge whether the plug is recovered in place, thereby increasing the safety margin of the system.

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
