For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1-9 As shown, an internal wiring assembly for a power distribution cabinet includes a power distribution cabinet 1, a fixing slide rail 3 for fixing electrical components 2, a safety mechanism 5 to prevent electrical components 2 from slipping out of place, and a locking mechanism 4 for detecting the safety mechanism 5.

[0032] The insurance mechanism 5 includes a horizontal tie rod 51, a fixed seat 52, and an inner locking block 53. The fixed seat 52 is formed on the fixed slide rail 3. The horizontal tie rod 51 is slidably arranged on the inner side of the fixed seat 52. Several inner locking blocks 53 are slidably arranged on the fixed seat 52 corresponding to the front end face. A push rod 54 is vertically slidably fitted on the inner locking block 53. The push rod 54 extends out of the bottom of the fixed seat 52. The inner locking block 53 is formed with a groove 531 that limits the range of motion of the push rod 54. The front end face of the push rod 54 is fitted with the fixed seat 52 through a limiting block 541.

[0033] The locking mechanism 4 includes a longitudinal guide rod 41, which works in conjunction with a transverse pull rod 51 via a pressing component. The front end of the longitudinal guide rod 41 is connected to the door of the distribution cabinet 1 via a touch switch. This touch switch is a common push-to-open drawer type touch switch, so its working principle will not be described again.

[0034] In this embodiment, the slide groove 531 on the inner locking block 53 has a side opening, the opening direction of which corresponds to the direction of the longitudinal guide rod 41. The inner side of the slide groove 531 corresponding to the opening direction has an anti-disengagement groove 532, which is an arc-shaped concave shape. The slide groove 531 has an auxiliary discharge chamfer 533 corresponding to the opening position. With the use of the arc structure, when the inner shrink block 53 is not fully pushed inward, the push rod 54 will be stuck in the anti-disengagement groove 532 to avoid disengagement.

[0035] In this embodiment, the fixed base 52 is formed with a vertical groove corresponding to the push rod 54. The push rod 54 has three states: unengaged state, locked state, and released state. In the released state, it rotates around the limit block 541 as the center. By utilizing the unassembled state of the push rod 54, the inner shrink block 53 is locked and the position of the front electrical component 2 is protruded, which can be effectively observed.

[0036] In this embodiment, the transverse pull rod 51 has a release block 511 and a reset block 512 formed on the end face of the push rod 54. The distance between the release block 511 and the reset block 512 is greater than the width of the push rod 54. When the release block 511 is in its initial position, it has a chamfer formed near the side of the push rod 54. The release block 511 and the reset block 512 are used to limit and push the rising push rod 54 to ensure the state change of the push rod 54.

[0037] In this embodiment, the squeezing assembly includes a release squeezing block 42 and a transverse squeezing block 43. The transverse squeezing block 43 is fixedly connected to one end of the transverse pull rod 51. The release squeezing block 42 is correspondingly provided on the upper side of the transverse squeezing block 43. The release squeezing block 42 is fixedly connected to the longitudinal guide rod 41. When the transverse pull rod 51 cannot be in place, the trigger switch cannot be pressed inward. Therefore, the longitudinal guide rod 41 cannot be moved downward by the top pressure and cannot effectively squeeze the release squeezing block 42 and the transverse squeezing block 43 downward, thereby providing an alarm.

[0038] In this embodiment, the width of the anti-detachment groove 532 is 1.5 times the thickness of the push rod 54, and the opening size of the slide groove 531 is larger than the thickness of the push rod 54.

[0039] In this embodiment, the push rod 54 flips at an angle of 15° from the locked state to the released state.

[0040] Working principle: When an electrical component 2 needs to be installed at the position corresponding to a certain push rod 54, the two locking blocks of the electrical component 2 are pressed onto the fixed slide rail 3 in sequence from bottom to top. At this time, the push rod 54 will first contact the pressure at the lower end and the push rod 54 will be pushed inward. When the push rod 54 moves upward, it will be stuck between the inner shrink block 53 and the release block 511. When the electrical component 2 is pushed inward, when the inner shrink block 53 is compressed inward to the position, the opening of the slide groove 531 corresponds to the push rod 54. If it is not pressed in place, the anti-disengagement groove 532 in the slide groove 531 will lock the push rod 54.

[0041] After all electrical components 2 are installed, if all electrical components 2 are in place, all corresponding retractable blocks 53 will be pushed inward and pressed. When the cabinet door needs to be closed, the touch switch at the door hinge will be pressed in, and the longitudinal guide rod 41 and the release compression block 42 will move down to compress the transverse compression block 43. The transverse compression block 43 will drive the transverse pull rod 51 to move laterally. The transverse pull rod 51 will drive the release block 511 to drive the push rod 54 to flip, thereby locking the position.

[0042] If the pressure is not applied properly, and one of the inner retraction blocks 53 is not pushed inward to the correct position, the inner retraction block 53 cannot release the push rod 54. The push rod 54 will then jam the release block 511 and the horizontal pull rod 51, and the cabinet door in the opposite direction cannot be closed. In this case, it is necessary to check which electrical component 2 is not installed properly. The cabinet door can only be closed after it is installed properly.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
