Example 1
As shown in fig. 1 to fig. 4, it is a wire pressing structure 10 for external connection of a transfer switch of the present invention, including: a base 11, external wires 12 and a front cover 13. The base 11 is fixedly connected to the front cover 13 and compresses the external wires 12 between the base 11 and the front cover 13. The base 11 has a slot 1111 formed therein, a compression block 14 inserted into the slot 1111, and a compression protrusion 131 formed on the inner side of the front cover 13, the compression protrusion 131 being used to compress the external wire 12 into the compression block 14. Specifically, the pressing block 14 is formed with a first pressing groove 141, the first pressing groove 141 is used for the external wire 12 to be inserted into, the pressing protrusion 131 is formed with a second pressing groove 1311, and the second pressing groove 1311 is also used for the external wire 12 to be inserted into. During installation, the external connection wire 12 is clamped into the first pressing groove 141, the pressing protrusion 131 is clamped above the external connection wire 12 through the second pressing groove 1311, and the base 11 and the front cover 13 are fixedly connected, so that the external connection wire 12 is firmly fixed in the first pressing groove 141 and the second pressing groove 1311 through the pressing block 14 and the pressing protrusion 131.
Further, the pressing block 14 is made of an elastic material, and the pressing block 14 is also formed with a plurality of hollowed holes 142. The pressing block 14 made of elastic material has a certain elastic pressing force on the external wire 12, and the pressing block 14 is further provided with a plurality of hollowed holes 142 for allowing the pressing block 14 to perform compression deformation, so that the pressing force of the pressing block 14 on the external wire 12 can be further improved. That is, after the base 11 is fixedly connected to the front cover 13, the pressing protrusion 131 presses the external wire 12 in the first pressing groove 141, and at this time, the pressing block 14 is deformed by a force and exerts a reverse acting force on the external wire 12 due to its own elastic force, thereby improving the stability of pressing the external wire 12.
The line pressing structure 10 of the external line of the change-over switch compresses the external line 12 through the cooperation of the compression block 14 and the compression convex part 131, so that a part of a screw is omitted, the previous large screw process is eliminated, the risk of screw sliding is avoided, and the production efficiency and the production quality of products are improved while the production cost of the products is greatly reduced. In addition, the plurality of hollow holes 142 arranged on the pressing block 14 can also improve the pressing force of the pressing block 14 on the external lead, and ensure the stability of fixing the external lead 12.
In a specific embodiment, the pressing block 14 has a central axis, and a plurality of hollow holes 142 are oppositely disposed along two sides of the central axis of the pressing block 14, so as to form a plurality of hollow hole groups 143. In the extending direction of the central axis, a curved elastic portion 144 is formed between two hollow holes 142 in one hollow hole group 143 disposed adjacent to the first pressing groove 141. The curved elastic portion 144 is capable of making the pressing block 14 more easily compressed after being stressed, so as to avoid the external wire 12 from being crushed due to excessive pressure when the external wire 12 is installed.
Further, a plurality of anti-slip ribs 145 are formed in the first pressing groove 141. The anti-slip rib 145 prevents the outer wire 12 from slipping in the first pressing groove 141.
In a specific embodiment, a slope 146 is further formed at the notch of the first pressing groove 141. The inclined surface 146 serves to guide the external wire 12 into the first pressing groove 141. Meanwhile, a gap is formed between the inclined surface 146 and the pressing protrusion 131. The clearance serves to allow the external wire 12 to be slightly deformed when being pressed and to accommodate a portion of the deformed external wire 12. In this way, when the external lead 12 is mounted, the external lead 12 is prevented from being crushed due to excessive pressure applied to the external lead 12.
As a specific embodiment, the press convex portion 131 is formed with a heat dissipation groove 1312. The heat dissipation groove 1312 communicates the second pressing groove 1311 and the outside of the pressing protrusion 131 for dissipating heat of the external connection wire 12 pressed in the second pressing groove 1311.
In a specific embodiment, the base 11 is provided with an insertion block 111, and the insertion block 111 is formed with the insertion groove 1111. The insert block 111 is also formed with a communication groove 1112. The communicating groove 1112 communicates the hollow hole 142 and the outside of the insert 111, so that the air in the hollow hole 142 of the compact block 14 inserted into the insert 1111 is discharged to the outside of the insert 1111, thereby ensuring the compression performance of the compact block 14.
Further, the insert block 111 is made of an elastic material. Support ribs 1113 are provided on both sides of the insert block 111 for reinforcing the stability of the insert block 111. Thus, when the external connection wire 12 is subjected to a certain degree of external force, the external connection wire 12 can be prevented from being pulled hard by slight deformation of the insertion block 111, so that the external connection wire 12 is protected to a certain extent.
As a specific embodiment, a first support portion 112 is formed at a position of the base 11 for leading out the external wires 12, a second support portion 132 is formed at a position of the front cover 13 for leading out the external wires 12, and a first locking hole 1121 is formed at the first support portion 112. The second supporting portion 132 is formed with a second chucking hole 1321. When mounting, the first supporting portion 112 is engaged with the second engaging hole 1321, and the external wire 12 is engaged with the first engaging hole 1121, thereby supporting the external wire 12.
The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
