DETAILED DESCRIPTION

[0024] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0026] Reference example Figures 1 to 4 A primary and secondary integrated pole mounted circuit breaker convenient for wiring comprises a circuit breaker body 1, wherein the circuit breaker body 1 is provided with an upper conductive plate 2 and a lower conductive plate 3, wherein the upper conductive plate 2 and the lower conductive plate 3 are provided with fixing holes 4, wherein the upper conductive plate 2 and the lower conductive plate 3 are provided with a clamping plate 5 movable up and down, wherein the fixing hole 4 is provided with a support portion 41, wherein the clamping plate 5 is provided with a movable portion 51 which can be spread to both sides, wherein the clamping plate 5 is provided with an elastic member 6, and acts on the clamping plate 5, so that the clamping plate 5 is closely attached to the upper conductive plate 2 and the lower conductive plate 3, so that the movable portion 51 is inserted into the fixing hole 4 and abuts against the support portion 41, so that the movable portion 51 is closely attached to the inner wall of the fixing hole 4;

[0027] It is worth mentioning that the upper conductive plate 2 and the lower conductive plate 3 are provided with a plurality of through holes 7, and the through hole 7 is provided with a blind hole 71 with the fixing hole 4 as the center. The through hole 7 provides a guide for the guide column 52, and the blind hole 71 provides a receiving space for the elastic member 6, and at the same time, serves as a movable limit for the upward movement of the clamping plate 5;

[0028] It is worth mentioning that the clamping plate 5 is provided with a guide column 52, which is slidably arranged in the through hole 7. The end face of the guide column 52 is provided with a retaining ring 53, and the retaining ring 53 is provided with a hollow column 54. The clamping plate 5 is provided with a handle 55. The guide column 52 is used in conjunction with the through hole 7, and the retaining ring 53 bears the force of the elastic member 6. When the end face of the hollow column 54 abuts against the end face of the blind hole 71, it not only protects the elastic member 6 and prevents the elastic member 6 from being subjected to excessive compression, resulting in a decrease in elastic potential energy, but also limits the movable distance of the clamping plate 5 moving upward. The handle 55 facilitates the user to operate the clamping plate 5.

[0029] It is worth mentioning that the elastic member 6 is arranged in the hollow column 54, and abuts against the blind hole 71 and the retaining ring 53, and acts on the retaining ring 53. The elastic member 6 is arranged as a spring, and the elastic force of the elastic member 6 is applied to the retaining ring 53, so that the clamping plate 5 moves downward and is closely attached to the upper conductive plate 2 and the lower conductive plate 3.

[0030] It is worth mentioning that chamfers 8 are provided on both sides of the opening portion 41 and the movable portion 51. The chamfers 8 facilitate the opening portion 41 to enter the middle of the movable portion 51, reducing the friction between the two. Moreover, the chamfers 8 also make the movable portion 51 expand outwardly with a larger total diameter as it goes deeper into the fixing hole 4, and thus the connection with the fixing hole 4 is more stable. The movable portion 51 can be made of plastic and has a certain elasticity.

[0031] It is worth mentioning that the number of the fixing holes 4 is set to at least two, and the shape of the movable portion 51 is set to be semicircular. It is best to place only one wiring terminal in a single fixing hole 4, so as to ensure the connection stability between the wiring terminal and the upper conductive plate 2 and the lower conductive plate 3. The semicircular shape fits the inner wall of the fixing hole 4 better.

[0032] It is worth mentioning that the upper conductive plate 2 and the lower conductive plate 3 are provided with a movable protective cover 9, and are located above the clamping plate 5. The protective cover 9 is provided with a rain shield 91, and is located on both sides and in front of the clamping plate 5. The protective cover 9 prevents rain from dripping onto the clamping plate 5, and the rain shield 91 prevents rain from being affected by natural wind and entering between the clamping plate 5 and the upper conductive plate 2 and the lower conductive plate 3, thereby preventing the conductive column and the elastic member 6 from being corroded, resulting in stagnation in the up and down movement of the clamping plate 5.

[0033] The use principle of the utility model is now described as follows:

[0034] When the terminal block needs to be installed, the protective cover 9 is rotated to apply an upward force to the handle 55, so that the clamping plate 5 leaves the upper conductive plate 2 or the lower conductive plate 3, and the movable portion 51 is higher than the fixing hole 4, until the hollow column 54 enters the blind hole 71 and abuts against the end surface of the blind hole 71, and the clamping plate 5 stops moving. At this time, the elastic member 6 is squeezed and stores energy;

[0035] The aperture of the terminal block is aligned with the fixing hole 4, and the force applied to the handle 55 is released. The elastic member 6 releases the elastic force to the retaining ring 53, so that the clamping plate 5 moves downward, and the movable portion 51 passes through the hole of the terminal block and enters the fixing hole 4, and is squeezed by the opening portion 41, so that the movable portion 51 moves to both sides with the center of the opening portion 41, and is tightly attached to the inner wall of the fixing hole 4. The clamping plate 5 makes the terminal block tightly attached to the upper conductive plate 2 or the lower conductive plate 3, thereby completing the connection and fixation of the terminal block.

[0036] The above design scheme can enable the product to achieve the advantages of having protection function, convenient connection and reliable connection.

[0037] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
