[0018] Furthermore, the socket module is provided with a support plate for fixing the motor, the support plate is provided with a guide shaft, the guide shaft is located on both sides of the lead screw, and the slide table slides on the guide shaft.

[0019] The advantage of adopting the above technical solution is that the receiving plate plays a fixing role, and the guide shaft plays an auxiliary guiding role, ensuring smooth movement of the slide table and smooth contact between the plug module and the socket module.

[0020] Furthermore, the plug guide post has an opening groove on its side, and the lower end of the plug-in metal piece extends into the plug guide post, while the upper end extends into the plug module.

[0021] The advantages of adopting the above technical solution are that the plug guide post plays the role of plug-in guidance, the metal plate plays the role of connection, and the upper end of the plug metal plate enters the plug module for wiring and connection of electrical equipment, etc.

[0022] Furthermore, the guide groove includes a coarse guide groove and a fine guide groove. The coarse guide groove is disposed on the upper side and is connected to the fine guide groove. The width of the fine guide groove is smaller than that of the coarse guide groove.

[0023] The advantage of adopting the above technical solution is that, during the insertion process, the coarse guide groove plays an initial guiding role, and then the fine guide groove allows the plug guide post to be accurately inserted into the plug guide hole, ensuring the connection between the plug and the socket.

[0024] Furthermore, the electrical terminal includes a terminal body, the terminal body having symmetrical protruding ends, the protruding ends being disposed close to each other, and the ends having outward openings.

[0025] The advantage of adopting the above technical solution is that, during insertion, the plug-in metal piece enters the terminal body through the opening to achieve conductivity. Attached Figure Description

Detailed Implementation

[0037] The present invention will now be described in further detail with reference to the accompanying drawings.

[0038] like Figure 1 , 2 As shown in Figure 8, this utility model discloses a fully sealed electrical switching device, comprising:

[0039] The plug module includes: a plug housing 1, a plug sealing structure 2, and a plug guide post 3. The sealing structure is disposed around the plug guide post 3, and a plugging metal piece 31 is disposed inside the plug guide post 3.

[0040] The socket module includes: a socket housing 4, electrical terminals 41, and a socket sealing structure. The electrical terminals 41 are movably disposed within the socket housing 4. The socket housing 4 is provided with a plug guide hole 42 for the plug guide post 3 to pass through. The socket sealing structure includes a sealing guide post 5, which is movable up and down. When not plugged in, the sealing guide post 5 seals the plug guide hole 42. When plugged in, the electrical terminals 41 make contact with the plug-in metal piece 31 and conduct electricity.

[0041] The advantage of adopting the above technical solution is that it achieves full sealing of the plug module and socket module, has good waterproof performance, and ensures safe use.

[0042] In some implementation schemes, such as Figure 2 , 5As shown, the plug housing 1 is provided with a guide block, and the socket module is provided with a guide groove 43. The guide block and the guide groove 43 cooperate to make the plug housing 1 and the socket housing 4 slide relative to each other. The guide blocks are symmetrically arranged to play a guiding role.

[0043] Furthermore, the guide groove 43 includes a coarse guide groove 431 and a fine guide groove 432. The coarse guide groove 431 is located on the upper side, and the coarse guide groove is connected to the fine guide groove 432. The width of the fine guide groove 432 is smaller than that of the coarse guide groove 431. Similarly, the upper width of the guide block is greater than the lower width.

[0044] During the insertion process, the coarse guide groove 431 serves as an initial guide, and then the fine guide groove 432 ensures that the plug guide post 3 is precisely inserted into the plug guide hole 42, thus guaranteeing the connection between the plug and the socket.

[0045] In some implementation schemes, such as Figure 3 As shown, the socket sealing structure also includes: a sealing elastic element 51 and a bottom cover 52. A movable groove 53 is provided inside the socket housing 4. The movable groove 53 is located below the plug guide hole 42. The sealing elastic element 51 is a spring sleeved on the sealing guide post 5, and its bottom abuts against the bottom cover 52. The bottom cover 52 is provided with a protruding post to limit the position of the spring. A sealing gasket is provided on the top of the sealing guide post 5 and presses against the plug guide hole 42 to form a seal. The bottom cover 52 is detachably installed on the bottom of the socket housing 4. The sealing guide post 5 can move up and down. When not plugged in, under the action of the sealing elastic element 51, the top of the sealing guide post 5 seals the plug guide hole 42, realizing the automatic sealing and waterproof function of the socket. When plugged in, the sealing guide post 5 is pressed down, and the plug guide post 3 enters into the plug guide hole 42 to realize the connection between the plug and the socket.

[0046] In some implementation schemes, such as Figure 4 As shown, the socket module also includes a moving component, including a motor 6, a lead screw 61, a nut, and a slide 62. The lead screw 61 is connected to the output end of the motor 6, and the nut reciprocates on the lead screw 61. The slide 62 is fixed to the nut, and the electrical terminal 41 is mounted on the slide 62. The motor 6 is horizontally mounted inside the socket housing 4, with the lead screw 61 facing the plug module. When the motor 6 rotates, it drives the lead screw 61 to move, which in turn drives the slide 62 to reciprocate. The electrical terminal 41 is mounted on the slide 62 and can be locked in place. The other end of the electrical terminal 41 is connected to a toggle plate 64, which can be connected to a power supply device. The motor 6 drives the slide 62 to move, which in turn drives the electrical terminal 41 to move, allowing the electrical terminal 41 to be inserted into the plug guide post 3 and energized. When the slide 62 moves in the reverse direction, the plug and socket are de-energized.

[0047] Furthermore, the socket module is provided with a support plate 63 for fixing the motor 6. The support plate 63 is provided with a guide shaft, which is located on both sides of the lead screw 61 and is parallel to the lead screw 61. Both ends are fixed to the support plate 63. The slide table 62 slides on the guide shaft, which plays an auxiliary guiding role and ensures that the slide table 62 moves smoothly.

[0048] In some embodiments, the locking device includes a locking block 7, the plug housing 1 is provided with a groove 12 that mates with the locking block 7, the locking block 7 is provided with an inclined surface facing the socket housing 4, and the groove 12 is provided with an inclined surface that mates with the inclined surface of the locking block 7, so as to ensure that the plug module and the socket module are securely connected.

[0049] Furthermore, a locking hook 71 is provided at the other end of the locking block 7. The locking hook 71 is fixedly connected to the locking block 7 as a whole. The locking hook 71 is set downward. A toggle plate 64 is attached to the slide table 62. The outer side of the toggle plate 64 contacts the locking hook 71, and the locking hook 71 is moved. A receiving cavity is provided at the upper part of the socket module. The main body of the locking block 7 passes through the receiving cavity and is fitted with a spring. The entire main body of the locking block 7 can move left and right in the receiving cavity.

[0050] When locking and plugging are required, the slide 62 moves toward the plug module. At this time, under the action of the spring, the locking block 7 extends outward and enters the groove 12 to lock. When opening is required, the slide 62 and the toggle plate 64 move in opposite directions, and the locking tongue hook 71 moves. The slide 62 and the locking tongue hook 71 are always in contact, which drives the locking block 7 to move in the opposite direction, so as to separate the locking block 7 from the groove 12.

[0051] In some implementation schemes, such as Figure 5 , 6 As shown, the plug guide post 3 has an opening groove 32 on its side. The plug is fixedly installed on the plug housing 1, facing downwards. There are multiple plugs, and the interior is hollow. The lower end of the plug metal piece 31 extends into the plug guide post 3 and is fixed inside the plug housing 1. It can be fixed by adhesive or direct injection molding. The number of plugs is the same as the number of plug guide posts 3. The upper end extends into the plug module and wiring is done inside the plug module to connect to the electrical equipment.

[0052] Furthermore, as shown in the figure, the electrical terminal 41 includes a terminal body 411, the terminal body 411 is provided with symmetrical protruding ends 412, the protruding ends 412 are closely arranged, the protruding ends 412 have a certain elasticity, and the end is provided with an outward opening, which can clamp the plug-in metal piece 31 when plugged in, to ensure the electrical connection between the plug and the socket.

[0053] The specific working process is as follows: Before the plug module and socket module are inserted, the sealing elastic element 51 is released, and the sealing guide post 5 is pressed upward along the guide groove 43 inside the socket housing 4. It is sealed with the upper end by the sealing gasket fixed on it, ensuring the entire housing is sealed. The slide table 62 is located near the end of the motor 6. The side of this slide table 62 contacts the locking hook 71 and moves it to the side near the end of the motor 6, thereby moving the locking block 7 to the side near the motor 6 as well, and the spring is in a compressed state. When the plug module is first inserted, the guide block 11 on the plug module contacts the socket coarse guide groove 431 of the socket module. When it is inserted a certain distance downward, the guide block 11 contacts the fine guide groove 432. After fine guidance, the plug guide post 3 of the plug module is just aligned and in contact with the sealing guide post 5 of the socket module. As it continues to be inserted downward, the plug guide post 3 will drive the sealing guide post 5 to move downward until it is inserted to the bottom. At this time, the sealing elastic element 51 is in a compressed state, and the plug guide post 3 moves into the moving groove 53 of the socket module. The entire process is completely sealed due to the plug sealing structure 2. Then, after the insertion is detected by an external signal or sensor, the motor 6 actuates, driving the nut and slide 62 to move linearly away from the motor 6 via the lead screw 61. Simultaneously, the slide 62 drives the locking device to move in the same direction, and the locking block 7 extends, engaging with the groove 12 of the plug module to lock the plug module and socket module. The motor 6 continues to move, driving the electrical terminal 41 to move linearly away from the motor 6 via the slide 62, eventually contacting the plug-in metal piece 31 of the plug module and conducting an electrical signal.

[0054] When the plug module and socket module are disconnected, the motor 6 operates in the opposite direction, first disconnecting the electrical terminal 41 from the plug-in metal piece 31, and then disconnecting the locking device. After the plug is pulled out, the sealing elastic element 51 is released, and the sealing guide post 5 returns to the state of sealing with the socket housing 4 through the sealing gasket, realizing the automatic switching of electrical signals.

[0055] Specifically, the plug of this device can be connected to a battery device, and the socket can be connected to a charging power source. Both can achieve a charging process with a high level of protection, making it applicable to automation and robotics fields.

[0056] In particular, the moving components of this device can also be powered by other sources and implemented in other ways.

[0057] The plug sealing structure 2 can be a sealing ring or a bellows-like sealing structure to achieve complete protection of the electrically conductive metal piece inside the plug module.

[0058] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
