[0011] Preferably, a guide structure is provided between the cover plate and the blocking plate, comprising two guide blocks provided in parallel and spaced apart on one end of the blocking plate close to the busbar body, and guide grooves provided in parallel and spaced apart on the cover plate for the two guide blocks to be inserted into and guide the movement of the guide blocks.

[0012] With the above arrangement, the guide blocks provided on one end of the blocking plate close to the busbar body can slide in the guide grooves, thereby guiding the movement of the blocking plate.

[0013] Preferably, a limiting component is provided between the guide grooves and the guide blocks, capable of limiting the sliding movement therebetween when the guide blocks move to the two ends of the guide grooves and requiring a certain external force to be applied to remove the limitation.

[0014] Preferably, the limiting component comprises a limiting groove with a width greater than that of the guide groove, and elastic clamping members provided on both ends of the guide blocks and capable of being inserted into the limiting groove.

[0015] With the above arrangement, the elastic clamping members provided on both ends of the guide blocks can be inserted into the limiting groove when the blocking plate moves to the two ends of the guide grooves. At this time, the elastic clamping members limit the movement of the blocking plate, reducing the probability of the blocking plate sliding on the cover plate, and allowing the blocking plate to maintain the state of closing the mounting holes or opening and closing the mounting holes.

[0016] Preferably, the bottom of the guide block is provided with an assembly structure that facilitates loading into the guide groove while avoiding falling out of the guide groove.

[0017] Preferably, the assembly structure comprises a first elastic clamping hook provided on at least one guide block away from the blocking plate and capable of abutting against the end of the cover plate close to the busbar body after being inserted into the guide groove.

[0018] With the above arrangement, the first elastic clamping hook provided on the end of the guide block away from the blocking plate can abut against the top of the cover plate when it passes through the guide groove, thereby reducing the probability of the guide block falling out of the guide groove and the probability of the blocking plate detaching from the cover plate.

[0019] Preferably, the outer wall of the baffle is provided with anti-skid lines for increasing the anti-skid performance.

[0020] With the above arrangement, the anti-skid lines provided on the outer wall of the baffle can increase the roughness of the surface of the baffle, thereby increasing the friction when the operator contacts the baffle, making it more convenient for the operator to slide the baffle.

[0021] Preferably, an assembling structure is provided between the baffle and the enclosure for quick assembly of the two.

[0022] Preferably, the assembling structure comprises a clamping groove recessed on the inner wall of the opposite sides of the enclosure and a second elastic clamping hook extending downward from the bottom of the baffle and clamped with the clamping groove after the baffle is installed on the top of the enclosure.

[0023] With the above arrangement, the second elastic clamping hook provided on the bottom of the baffle can be inserted into the clamping groove on the enclosure when the baffle is installed on the top of the enclosure, and clamped with the clamping groove, thereby realizing the assembly between the baffle and the enclosure.

[0024] The utility model discloses have remarkable technical effect because of adopting above technical scheme: the protective structure that sets up on the top of the enclosure can stop the opening of the top of the enclosure after the installation of bolt, reduces the probability that operator contacts bolt head, thereby reduces the probability that operator is electrocuted because of contacting bolt head.
