Technical Field

[0001] The utility model belongs to the technical field of junction boxes, and more specifically, relates to a precision busbar junction box. Background Art

[0002] A precision busbar refers to a shared pathway to which multiple devices are connected in the form of parallel branches. Currently, the busbar is generally installed and fixed inside a junction box, making it convenient for external devices to connect to the precision busbar through cables to obtain power or signal exchange.

[0003] When the existing precision busbar junction box is in use, the busbar is generally installed on the innermost side of the box. Due to the small space inside the box and poor optical fiber, the branch cable and busbar are difficult to install and remove. After installation, poor contact is likely to occur between the branch cable and the busbar, resulting in poor stability and low practicality. Utility Model Content

[0022] The embodiments of the present invention are described in further detail below with reference to the accompanying drawings and examples.

[0023] As attached Figure 1 To the attached Figure 6 As shown:

[0024] Example 1: The utility model provides a precision busbar junction box, including a box assembly 1, the box assembly 1 includes a protective box 101, a safety door 102 and a mounting plate 103, the safety door 102 is rotatably connected to the side of the protective box 101, and the mounting plate 103 is inserted into the interior of the protective box 101; a limit assembly 2, the limit assembly 2 includes a positioning control rod 201 and an ejection limit block 202, the ejection limit block 202 is inserted into the interior of the protective box 101, and the positioning control rod 201 is rotatably connected to the interior of the protective box 101.

[0025] In the embodiment of the present disclosure, a push-out spring 1031 is provided inside the mounting plate 103, and the two ends of the push-out spring 1031 respectively press against the inside of the mounting plate 103 and the inside of the protective box 101. A reset block 1021 is provided on the side of the safety door 102, and when the safety door 102 is in the closed state, the reset block 1021 can push the mounting plate 103 to the innermost side of the protective box 101. In use, when the safety door 102 is in the closed state, the reset block 1021 can contact and squeeze the mounting plate 103, so that the mounting plate 103 is located at the innermost side of the protective box 101 for positioning and use, thereby realizing the protection of the mounting plate 103 and its external lines. When the safety door 102 is opened, the resistance and limiting effect of the reset block 1021 on the mounting plate 103 becomes invalid, so that under the action of the push-out spring 1031, the mounting plate 103 will be pushed out of the protection box 101, thereby increasing the operating space of the staff, facilitating various installation and removal operations of the busbar and branch cables, and ensuring stable installation. When the open safety door 102 is closed, as the safety door 102 rotates, the reset block 1021 will push the mounting plate 103 into the innermost side of the protection box 101 again through resistance and extrusion, which is convenient and flexible to use.

[0026] In the embodiment of the present disclosure, a track block 1032 is provided on the side of the mounting plate 103, and a track groove 1011 is provided inside the protective box 101. The track block 1032 is inserted into the inside of the track groove 1011. During use, the track groove 1011 can limit the moving trajectory of the mounting plate 103 through the track block 1032, so that the mounting plate 103 will not be skewed or twisted during movement, causing the device to be stuck and fail, and the use is stable.

[0027] In the embodiment of the present disclosure, the rod body of the positioning control rod 201 is provided with a thread on the outside, and the positioning control rod 201 is screwed to the inside of the push-out limit block 202 through the rod body thread. The cross-sectional shapes of the track block 1032 and the push-out limit block 202 are both "T"-shaped, and the push-out limit block 202 and one of the track blocks 1032 are located in the same track groove 1011. The rod body of the positioning control rod 201 passes through the inside of the track block 1032. In use, the limit assembly 2 can limit the maximum push-out distance of the mounting plate 103 when the safety door 102 is opened, thereby making the box assembly Component 1 can be used in different working environments. When the mounting plate 103 moves outward under the action of the push-out spring 1031, one of the track blocks 1032 will be blocked by the push-out limit block 202 and cannot move, so that the mounting plate 103 cannot be pushed out any further. When the positioning control rod 201 is rotated, the positioning control rod 201 can drive the push-out limit block 202 to move and change the use position through the rod body thread. The change of the use position of the push-out limit block 202 changes the maximum push-out distance between the track block 1032 and the mounting plate 103. It is easy to adjust, flexible to use, and highly adaptable.

[0028] The specific usage and function of this embodiment are as follows:

[0029] When the safety door 102 is closed, the reset stop 1021 can contact and squeeze the mounting plate 103, so that the mounting plate 103 is located at the innermost side of the protective box 101 for positioning and use, thereby protecting the mounting plate 103 and the cables outside the mounting plate 103. At this time, the push-out spring 1031 is in a compressed state. When the safety door 102 is opened, the reset stop 1021 has no effect on the resistance and limiting effect on the mounting plate 103. As a result, under the action of the push-out spring 1031, the mounting plate 103 will be pushed out of the protective box 101, thereby increasing the operating space for the staff, facilitating various installation and removal operations of the busbar and branch cables, and ensuring stable installation. When the open safety door 102 is closed, As the safety door 102 rotates, the reset block 1021 will push the mounting plate 103 into the innermost side of the protective box 101 again through resistance and extrusion. The limit assembly 2 can limit the maximum push-out distance of the mounting plate 103 when the safety door 102 is opened, so that the box assembly 1 can be used in different working environments. When the mounting plate 103 moves outward under the action of the push-out top spring 1031, one of the track blocks 1032 will be blocked by the push-out limit block 202 and cannot move, so that the mounting plate 103 cannot continue to be pushed out. When the positioning control rod 201 is rotated, the positioning control rod 201 can drive the push-out limit block 202 to move and change the use position through the rod body thread. The change in the use position of the push-out limit block 202 changes the maximum push-out distance between the track block 1032 and the mounting plate 103, which is convenient for adjustment.
