Description

Technical Field

[0001] This utility model relates to the field of contactor technology, specifically to an AC contactor. Background Technology

[0002] AC contactors are widely used in power switching and control circuits. They utilize contacts to open and close circuits, such as... Figure 7 As shown, the AC contactor has a terminal block, which consists of a wiring section, a wiring body, and a stationary contact mounting section. The stationary contact mounting section extends towards the wiring section. This configuration requires more waste of materials and increases the production cost of the product. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect of excessive material waste in the terminal block of the prior art, thereby providing an AC contactor that can reduce material waste.

[0004] Therefore, this utility model provides an AC contactor, including a housing and a terminal block disposed within the housing. The terminal block includes a connecting body, a wiring portion disposed on one side of the connecting body, and a stationary contact mounting portion disposed on the other side. The stationary contact mounting portion extends toward the side opposite to the wiring portion.

[0005] Furthermore, a connecting part is provided between the connecting body and the stationary contact mounting part, and the connecting body, the connecting part, and the stationary contact mounting part form a "Z" shaped structure.

[0006] Furthermore: the connecting body includes a positioning part connected to the connecting part and a flow guiding part connected to the wiring part, and the positioning part, the flow guiding part and the wiring part are arranged to form an "I" shaped structure.

[0007] Furthermore, the positioning part is provided with positioning holes through which external fastening nails pass to fix the terminal block to the housing.

[0008] Furthermore, the housing is provided with a support column capable of supporting the stationary contact mounting portion.

[0009] The technical solution of this utility model has the following advantages:

[0010] 1. The present invention provides an AC contactor in which the stationary contact mounting portion is disposed on the connecting body and extends to the side opposite to the wiring portion. Thus, in this embodiment, the total length of the terminal block is the sum of the length of the connecting body, the length of the wiring portion, and the length of the stationary contact mounting portion. In the prior art, the total length of the terminal block is the sum of the length of the wiring portion and the length of the wiring body. Therefore, when the total length of the terminal block in the prior art is the same as that in this embodiment, and the length of the wiring portion is the same in both, the connecting body in the prior art requires more material. Therefore, compared with the prior art, the terminal block in the prior art requires more material to manufacture, thereby increasing the production cost.

[0011] 2. The AC contactor provided by this utility model, through the setting of the connecting part, can support the stationary contact mounting part, so that the stationary contact on the stationary contact mounting part can contact the moving contact, thereby realizing the opening and closing of the AC contactor.

[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Example

[0028] This embodiment provides an AC contactor, including a housing 1 and a terminal block 2 disposed within the housing 1. The terminal block 2 includes a connecting body 21, a wiring portion 22 disposed on one side of the connecting body 21, and a stationary contact mounting portion 23 disposed on the other side. The stationary contact mounting portion 23 extends toward the side opposite to the wiring portion 22.

[0029] The specific improvements mentioned above are as follows: Figure 6As shown, compared to the prior art, the stationary contact mounting part 23 is provided on the connecting body 21 and extends to the side opposite to the wiring part 22. Thus, in this embodiment, the total length of the wiring board 2 is the sum of the length of the connecting body 21, the length of the wiring part 22, and the length of the stationary contact mounting part 23.

[0030] like Figure 7 As shown, in the prior art, the total length of the terminal block 2 is the sum of the length of the terminal block 22 and the length of the terminal block body;

[0031] Therefore, when the overall length of the terminal block in the prior art is the same as that in this embodiment, and the length of the wiring part is the same, the connection body in the prior art requires more material. Therefore, compared with the prior art, the terminal block in the prior art requires more material to manufacture, thereby increasing the production cost.

[0032] Based on the above embodiments: a connecting part 3 is provided between the connecting body 21 and the stationary contact mounting part 23, and the connecting body 21, the connecting part 3 and the stationary contact mounting part 23 form a "Z" shaped structure.

[0033] The specific improvements mentioned above are as follows: Figures 1-5 As shown, the connection part 3 can support the stationary contact mounting part 23, so that the stationary contact on the stationary contact mounting part 23 can contact the moving contact, thereby realizing the opening and closing of the AC contactor.

[0034] Based on the above embodiments: the connecting body 21 includes a positioning part 4 connected to the connecting part 3 and a flow guiding part 41 connected to the wiring part 22. The positioning part 4, the flow guiding part 41 and the wiring part 22 are arranged to form an "I" shaped structure.

[0035] The specific improvements mentioned above are as follows: Figure 5 As shown, to further avoid material waste without affecting product performance, the width of the current guide 41 is shortened. The applicant has conducted a large number of experiments and can effectively prove that the shortened width of the current guide 41 can still carry the current intensity of the product. Therefore, in this embodiment, the shortening of the current guide 41 saves materials and reduces production costs without affecting product performance.

[0036] Based on the above embodiments: the positioning part 4 is provided with positioning holes 5 for external fastening nails to pass through in order to fix the wiring board 2 to the housing 1.

[0037] The specific improvements mentioned above are as follows: Figure 4 As shown, in order to effectively fix the position of the terminal block 2, a positioning hole 5 is opened on the positioning part 4, and then a circular hole aligned with the positioning hole 5 is opened on the housing 1. The positioning hole 5 is aligned with the circular hole and threaded holes are provided in the hole. Finally, the fastening screw is screwed into the threaded hole.

[0038] Based on the above embodiments: the housing 1 is provided with a support column 6 that can support the stationary contact mounting part 23.

[0039] The specific improvements mentioned above are as follows: Figure 4 As shown, a support column 6 is provided on the housing 1. The support column 6 can support the stationary contact mounting part 23, thereby effectively supporting the entire terminal block 2 and preventing the stationary contact from shifting when the moving contact contacts the stationary contact.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
