Description

Technical Field

[0001] The utility model belongs to the technical field of circuit plugs and relates to a protection mechanism for an electronic circuit connection plug. Background Art

[0002] An electronic circuit connection plug, also known as an integrated electronic circuit connection plug, is a plug used to connect an integrated circuit to other electronic components or circuit boards. It is usually supported by metal or plastic and is used to transmit electrical signals, power, and ground wires, etc. to realize the functions of electronic devices. The jack design and layout of the plug need to match the terminal layout to ensure correct connection and signal transmission. The integrated electronic circuit connection plug plays an important role in the manufacturing and maintenance of electronic devices, enabling the integrated circuit to communicate and cooperate effectively with other electronic components and circuit boards.

[0003] When optimizing existing electronic circuit connection plugs, most of them are reflected in the tripping and locking methods. For example, the Chinese patent document with the publication number CN213212574U discloses a leakage protection plug, which includes a wire head, an upper clamping plate, and a lower clamping plate. One end of the upper clamping plate is fixedly installed with a docking block, and the bottom of the upper clamping plate is fixedly installed with clamping blocks at equal intervals. The upper surface of the lower clamping plate is provided with positioning grooves at equal intervals. Waterproof gaskets are provided on one side of the upper clamping plate and the lower clamping plate. The bottom of the lower clamping plate is fixedly installed with a plug iron sheet. One end of the upper clamping plate and the lower clamping plate are butt-jointed and installed with a wire head. A functional chamber is provided in cooperation with the upper clamping plate and the lower clamping plate. In the utility model, a circuit board and a temperature sensor are provided at the bottom of the functional chamber. Through the electrical connection between the temperature sensor and the circuit board, the temperature when the device is docked with the socket is sensed by the temperature sensor. Once the temperature is too high, an electrical connection is generated between the circuit board and the circuit control board to realize the emergency treatment of the release device, further preventing the internal components of the device from being damaged.

[0004] Although the above-mentioned leakage protection plug has certain advantages in the tripping and locking method, there are still certain deficiencies: the above-mentioned leakage protection plug completes the fixation between the upper and lower clamping plates through the clamping blocks at the bottom end of the upper clamping plate and the positioning grooves on the upper surface of the lower clamping plate. This fixing method is unstable and easily causes the upper and lower clamping plates to fall off, resulting in the internal components of the functional chamber being exposed. There is a circuit board and a temperature sensor inside the above-mentioned leakage protection plug. The circuit board being exposed has certain potential safety hazards. Therefore, the above-mentioned fixing device has certain safety risks. Content of the Utility Model

[0006] The purpose of the utility model is to provide a protection mechanism for an electronic circuit connection plug to improve the safety and stability of the connection plug.

[0007] (2) Technical solution

[0008] In order to solve the above technical problems, the utility model provides a protection mechanism for an electronic circuit connection plug, which comprises an upper clamping plate 1, a docking block 2, a lower clamping plate 3, a waterproof sealing gasket 4, a plug iron sheet 5, a wire head 6, and a functional compartment 7. One end of the upper clamping plate 1 is fixedly connected to the docking block 2. The lower part of the upper clamping plate 1 is provided with a lower clamping plate 3. A waterproof sealing gasket 4 is arranged between the upper clamping plate 1 and the lower clamping plate 3. A plug iron sheet 5 is arranged at the bottom of the lower clamping plate 3. One end of the upper clamping plate 1 and the lower clamping plate 3 is docked and installed with a wire head 6. A functional compartment 7 is cooperatively arranged between the upper clamping plate 1 and the lower clamping plate 3. A plurality of fixing devices 8 are arranged between the upper clamping plate 1 and the lower clamping plate 3. By pressing the upper clamping plate 1 and applying a force on the fixing device 8, the hanging connection or separation of the upper clamping plate 1 and the lower clamping plate 3 is realized.

[0009] Among them, the fixing device 8 comprises a pressing plate 81, a hook 82, a housing 83, a clamping block 84, a spring 85, a positioning rod 86, a buckle 87, and a movable limiting block 88. The top of the pressing plate 81 is fixedly connected to the bottom of the upper clamping plate 1. A hook 82 is arranged at the bottom of the pressing plate 81. A housing 83 is arranged below the hook 82, and the housing 83 is fixed on the lower clamping plate 3. Clamping blocks 84 are arranged on the left and right sides of the housing 83.

The rotating shaft 872 and the pull rod 871 cooperate with each other to fix the buckle 87. The rotating shaft 872 is used to assist the pull rod 871 to enter the guide track. After the spring 85 is compressed, the plane on the semicircle of the rotating shaft 872 is in close contact with the corresponding plane of the buckle 87. At this time, the initial state of the pull rod 871 forms an angle with the vertical direction. When the pull rod 871 moves downward to the lower left along the inclined plane, under the action of the spring 85, the pull rod 871 receives a moment of deflection to the right and enters the guide track.

[0029] Refer to Figure 1-2 As shown, the electronic circuit connection plug protection mechanism of this embodiment includes an upper clamping plate 1, a docking block 2, a lower clamping plate 3, a waterproof sealing gasket 4, a plug iron sheet 5, a wire head 6, and a functional compartment 7.

A waterproof sealing gasket 4 is arranged between the upper clamping plate 1 and the lower clamping plate 3. The bottom of the lower clamping plate 3 is provided with the plug iron sheet 5. One end of the upper clamping plate 1 and the lower clamping plate 3 is butt - installed with the wire head 6. A functional compartment 7 is cooperatively arranged between the upper clamping plate 1 and the lower clamping plate 3. Multiple groups of fixing devices 8 are arranged between the upper clamping plate 1 and the lower clamping plate 3. Press the upper clamping plate 1 to apply a force on the fixing device 8 to realize the hanging connection or separation of the upper clamping plate 1 and the lower clamping plate 3.

[0030] Refer toFigure 3-4 As shown, the fixing device 8 includes a pressing plate 81, a hook 82, a housing 83, a clamping block 84, a spring 85, a positioning rod 86, a buckle 87, and a movable limiting block 88; the top of the pressing plate 81 is fixedly connected to the bottom of the upper clamping plate 1, a hook 82 is arranged at the bottom of the pressing plate 81, a housing 83 is arranged below the hook 82, the housing 83 is fixed on the lower clamping plate 3, clamping blocks 84 are arranged on the left and right sides of the housing 83, one end of a spring 85 is fixedly connected to the bottom end inside the housing 83, a positioning rod 86 is arranged inside the spring 85, the other end of the spring 85 is elastically connected to the bottom of the buckle 87, the top of the buckle 87 is fixedly connected with a movable limiting block 88, and two groups of the movable limiting blocks 88 are arranged in a left-right symmetric manner.

[0031] Refer to Figure 1-4 As shown, through the mutual cooperation between the upper clamping plate 1 and the pressing plate 81, the user presses the upper clamping plate 1 to press the pressing plate 81.

[0032] The bottom of the housing 83 is fixedly connected to the inside of the lower clamping plate 3.

[0033] Refer to Figure 5 As shown, a pull rod 871 is arranged at the front end of the buckle 87.

[0034] The pull rod 871 is hinged to the buckle 87 through a rotating shaft 872, the rotating shaft 872 is semicircular, the rotating shaft 872 and the pull rod 871 cooperate with each other to fix the buckle 87, and the semicircular rotating shaft 872 is used to assist the pull rod 871 to enter the guiding track. After the spring 85 is compressed, the plane on the semicircle of the rotating shaft 872 is in close contact with the corresponding plane of the buckle 87. At this time, the initial state of the pull rod 871 forms an angle with the vertical direction. Therefore, when the pull rod 871 moves downward along the inclined plane to the position shown in the figure, under the action of the spring 85, the pull rod 871 naturally receives a moment to deflect to the right, and thus enters the guiding track.

[0035] Refer to Figure 1-5 As shown, an upper guiding block 831 and a lower guiding block 832 are arranged on the inner wall of the rear end of the housing 83, and the upper guiding block 831 is arranged at the lower end of the lower guiding block 832.

[0036] The upper guiding block 831 and the lower guiding block 832 are irregularly shaped, and a guiding track is formed between the upper guiding block 831 and the lower guiding block 832. By cooperating with the pull rod 871 and the rotating shaft 872, the guiding track realizes the fixation of the pull rod 871 and thus fixes the buckle 87.

[0037] In this embodiment, a hook 82 is provided at the center of the bottom of the pressing plate 81, and mounting holes are provided on both sides. The pressing plate 81 is fixed on the upper clamping plate 1 through the mounting holes. The hook 82 includes a connecting rod connecting the pressing plate 81 and an inverted trapezoidal block at the lower end of the connecting rod. The housing 83 is in the shape of a cuboid with an open upper part, and two clamping blocks 84 protrude upward and outward from the two side walls of the housing 83. There are two movable limit blocks 88, which are symmetrically arranged. Locking steps are provided on the opposite sides of the two movable limit blocks 88, and the locking steps cooperate with the inverted trapezoidal block to achieve locking.

[0038] The working principle of the electronic circuit connection plug protection mechanism in this embodiment is as follows:

[0039] When in use, the user presses the upper clamping plate 1. The upper clamping plate 1 applies force to the pressing plate 81. The pressing plate 81 indirectly applies force to the buckle 87 by pressing the hook 82. The buckle 87 moves downward, and at the same time drives the pull rod 871 to move along the upper end of the upper guiding block 831 to the left side of the upper guiding block 831. At this time, the spring 85 is compressed due to the downward movement of the buckle 87, and the plane on the semi-circle of the rotating shaft 872 is in close contact with the corresponding plane of the buckle 87. At this time, the initial state of the pull rod 871 forms an angle with the vertical direction. Therefore, when the pull rod 871 moves downward along the inclined plane to the position shown in the figure, under the action of the spring 85, the pull rod 871 naturally receives a moment of deflection to the right, and the pull rod 871 starts to enter the guiding track. After the user releases the hand, the pull rod 871 is clamped in the center of the guiding track along the guiding track between the upper guiding block 831 and the lower guiding block 832, and then is stuck. At this time, the movable limit block 88 is squeezed by the inner wall of the housing 83 and clamps the hook 82; if the user wants to separate the upper clamping plate 1 from the lower clamping plate 3, the upper clamping plate 1 needs to be pressed again. The upper clamping plate 1 presses the hook 82 again, the buckle 87 moves downward, and at the same time drives the pull rod 871 to move to the right along the guiding track. The pull rod 871 starts to leave the guiding track. After releasing the hand, the pull rod 871 moves along the right side inside the housing 83 and finally returns to the origin, so that the hook 82 is disengaged from the movable limit block 88, thus completing the separation of the upper clamping plate 1 from the lower clamping plate 3.

[0040] It can be seen from the above technical solutions that the present utility model has the following remarkable features:

[0041] In the present utility model, by providing a fixing device between the upper clamping plate and the lower clamping plate, through the cooperation between the hook and the buckle, when the hook at the bottom of the pressing plate is used to push the buckle downward, the two groups of movable limit blocks at the top of the buckle will rotate toward the middle with the rotating shaft as the axis due to encountering the clamping blocks of the housing, and are fixed between the guiding tracks of the upper guiding block and the lower guiding block, thus completing the fixation of the upper clamping plate and the lower clamping plate, preventing the upper clamping plate and the lower clamping plate from falling off and separating, thereby avoiding the exposure of the circuit components inside the functional compartment, reducing the risk, and further improving the safety of the connection plug.

The wiring diagram of the power element and the power supply are common knowledge in the art. Moreover, the present utility model is mainly used to protect mechanical devices, so the control mode and wiring arrangement of the present utility model will not be explained in detail herein.
