Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 and 2, the terminal block structure of the connection terminal is characterized in that the connection terminal 4 is installed on the casing 1, an operation hole 2 is formed in the casing 1 above the connection terminal 4, the terminal block structure 3 can be used for a circuit breaker, a leakage protector and the like having the casing 1 with the similar connection terminal 4, the terminal block structure 3 is inserted into the operation hole 2 to cover a screw 41 on the connection terminal 4, wherein the terminal block structure 3 is integrally formed and made of an insulating material, and meanwhile, the terminal block structure 3 has certain elasticity on the premise of having certain strength, for example, is made of an insulating plastic material.

As shown in fig. 3-6, the plug structure 3 includes a circular body 31, a guiding member 32 disposed on one side of the circular body 31, and a fastening member 33 disposed on the circular body 31, in the installation process, the guiding member 32 is obliquely inserted into the operation hole 2 and is disposed below the casing 1 beside the operation hole 2, the bottom of the corresponding guiding member 32 is blocked by the internal component of the casing 1, and then the circular body 31 is pressed into the operation hole 2, at this time, the circular body 31 rotates with the blocked portion of the guiding member 32 as an axis, the circular body 31 faces downward, the guiding member 32 faces upward until the circular body 31 completely enters the operation hole 2, at this time, the fastening member 33 cooperates with the casing 1 to fix the circular body 31 in the operation hole 2, thereby implementing the installation process of the plug structure 3.

Wherein, the guide 32 is formed on the side surface of the circular body 31, and a top surface 321, a bottom surface 322 and two side surfaces 323 are formed on the guide 32, after the installation is completed, the top surface 321 is close to the casing 1, the bottom surface 322 is far away from the casing 1, the two side surfaces 323 are positioned at two sides of the guide 32, the bottom surface 322 is inclined upwards from the bottom of the circular body 31 to form an inclined surface, and the two side surfaces 323 are inclined towards the middle from the circular body 31 to form two symmetrical inclined surfaces; a guide groove 5 is arranged in the housing 1, the guide member 32 can be inserted into the guide groove 5, the guide member 32 forms a component with three inclined surfaces, and when the guide member 32 is inserted into the guide groove 5, the three inclined surfaces can enable the plug structure 3 to be finally positioned at a required position; the top surface 321 is a plane, after the installation is completed, the top surface 321 abuts against the inner surface of the shell 1, the top surface 321 can prevent the circular body 31 from continuously rotating, the circular body 31 is kept at a required position, and meanwhile, the top surface of the circular body 31 and the shell 1 are set to be surfaces with the same inclination according to the inclined surface of the outer surface of the shell 1, so that the circular body 31 is flush with the outer surface of the shell 1, and the attractiveness is ensured; due to the matching of the guide piece 32 and the guide groove 5, the plug structure 3 can be installed only in one direction, and the circular body 31 can be always flush with the outer surface of the shell 1 after the installation is completed.

Further, in order to secure the mounting effect and reduce the weight, and save the material, weight-reducing grooves 324 are provided on both sides of the top surface 321, and the weight-reducing grooves 324 on both sides form a reinforcing rib in the middle of the guide 32, and the top of the reinforcing rib is the top surface 321 of the guide 32.

After the circular body 31 is pressed into the operation hole 2, the circular body 31 can be fixed through the buckling piece 33, the buckling piece 33 is a buckling protrusion extending outwards from the side surface of the circular body 31 along the radial direction, the buckling groove 6 is arranged at a corresponding position in the shell 1, when an operator presses the circular body 31 into the operation hole 2, the buckling protrusion slides into the buckling groove 6 from the upper side, the buckling protrusion is made of an elastic material and is inwards compressed to deform the circular body 31 when contacting with the shell 1, and after the buckling protrusion slides into the buckling groove 6, the circular body 31 pushes the buckling protrusion to recover and enter the buckling groove 6; since the guiding member 32 abuts against the inner surface of the housing 1, a rotating force in the opposite direction is applied to the circular body 31, and the engaging protrusion and the engaging recess 6 cooperate to counteract the rotating force, thereby securing the circular body 31 in the operation hole 2.

Furthermore, the buckling protrusion and the buckling groove 6 are arranged on one side far away from the guide piece 32, so that two forces which are mutually counteracted can be positioned on the same plane, and the balance is well realized; the buckling bulges and the buckling grooves 6 can also be arranged on two sides of the plane, and the joint force of two forces generated by the buckling bulges and the buckling grooves 6 is required to be ensured to be positioned in the plane, so that the mode not only can ensure the balance of installation, but also can ensure the stability of installation, and cannot shake up and down on two sides of the plane.

Because need rotate after circular body 31 inserts, have some to influence circular body 31 is to handle hole 2 internal rotation, so circular body 31 is kept away from guide 32 one side and is provided with the breach of stepping down 313 for dodging casing 1, the breach of stepping down 313 sets up in the lower part of circular body 31, can not influence the sheltering from to handle hole 2.

The circular body 31 includes a top plate 311 and a ring-shaped plate 312 extending downward from the top plate 311, the guiding element 32 and the fastening element 33 are both disposed on the ring-shaped plate 312, the guiding element 32 is disposed on the lower portion of the ring-shaped plate 312, the fastening element 33 is disposed on the upper portion of the ring-shaped plate 312, the relief notch 313 is disposed on the ring-shaped plate 312 and below the fastening element 33, and the upper surface of the top plate 311 is inclined.

After the plug structure 3 is buckled into the operation hole 2, when the maintenance operation needs to be carried out on the position, the plug structure 3 is inconvenient to take out, so that the disassembly is inconvenient; therefore, the thin-wall position 314 is arranged in the middle of the top plate 311, the wall thickness of the thin-wall position is thin, dust and moisture can be prevented from entering the thin-wall position 314 in normal use, when maintenance is needed, the thin-wall position 314 can be broken and pulled out by using a tool, the tool is a screwdriver, the screwdriver can enter a cavity surrounded by the annular plate 312 and the top plate 311 after the thin-wall position is punctured, then the plug structure 3 can be separated by tilting upwards, and a new plug structure 3 can be replaced after maintenance is finished.

To sum up, through the design of circular body 31, guide 32 and buckling piece 33, can make handle hole 2 by easy hiding to fix in the assigned position, can not appear dropping, dust and moisture can not very easily get into operation Kong Xiushi binding post, thereby can reduce the corrosion, improve its life, convenient to use through thin wall position 314 is to the dismantlement of this end cap structure 3.
