Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0027] Please see Figures 1-5 As shown, this embodiment is an embedded assembly-type connecting wire bar for an electromagnetic interlocking AC contactor, comprising:
[0028] Interlocking contactor 1, terminal block 2, limiting member 3, conductive member 4 and contact plate 5; terminal block 2 is snapped onto one end of interlocking contactor 1, limiting member 3 is located inside terminal block 2, conductive member 4 is located inside limiting member 3, and contact plate 5 is fixed to the surface of interlocking contactor 1.
[0029] The conductive component 4 includes a first in-phase return bus 41, a first connection pin 411, a second connection pin 412, a second in-phase return bus 42, a third connection pin 421, a fourth connection pin 422, a third in-phase return bus 43, a fifth connection pin 431, and a sixth connection pin 432. The first connection pin 411 and the second connection pin 412 are fixed to the outer surface of the bottom end of the first in-phase return bus 41, the third connection pin 421 and the fourth connection pin 422 are fixed to the outer surface of the bottom end of the second in-phase return bus 42, and the fifth connection pin 431 and the sixth connection pin 432 are fixed to the outer surface of the bottom end of the third in-phase return bus 43. The lower surfaces of the first connection pin 411, the second connection pin 412, the third connection pin 421, the fourth connection pin 422, the fifth connection pin 431, and the sixth connection pin 432 are in close contact with the upper surface of the contact plate 5.
[0030] The outer surfaces of the first in-phase return bus 41, the second in-phase return bus 42, and the third in-phase return bus 43 are encapsulated with insulating varnish with high insulation and high flame retardant properties. The bending structure of the first in-phase return bus 41, the second in-phase return bus 42, and the third in-phase return bus 43 is positioned and nested in the limiting frame 31 to form an assembled integrated busbar. A long commutation busbar, the second in-phase return busbar 42, and the short commutation busbar are nested inside the limiting frame 31 to form an assembled integrated commutation busbar.
[0031] Taking the busbar as an example, the assembly process of the busbar and the interlocking contactor 1 is explained in detail. When the busbar needs to be assembled with the interlocking contactor 1, the detachable terminal block 2 on the interlocking contactor 1 is removed first. The first connecting pin 411, the second connecting pin 412, the third connecting pin 421, the fourth connecting pin 422, the fifth connecting pin 431, and the sixth connecting pin 432 of the busbar are placed on the contact plate 5 of the interlocking contactor 1. The busbar and the interlocking contactor 1 are clamped together by the snap-fit structure. Then, the detachable terminal block 2 is snapped onto the interlocking contactor 1. By firmly pressing the first connecting pin 411, the second connecting pin 412, the third connecting pin 421, the fourth connecting pin 422, the fifth connecting pin 431, and the sixth connecting pin 432 to the contact plate 5 of the interlocking contactor 1, a reliable connection between the busbar and the interlocking contactor 1 is achieved.
[0032] A fixing frame 44 is fixed on both sides of the outer surface of the first in-phase return bus 41 and the second in-phase return bus 42. A connecting shaft 45 is fixed inside the fixing frame 44, and a rotating plate 46 is rotatably connected to the outer surface of the connecting shaft 45.
[0033] The fixed frame 44 is used to fix the first in-phase return bus 41 and the second in-phase return bus 42 to support the connecting shaft 45. The connecting shaft 45 is used to rotate the rotating plate 46 on its surface, and the rotating plate 46 is used to connect the fixed frame 44 and the fixed post 47.
[0034] The lower surfaces of the second and third phase return busbars 42 and 43 are fixed with fixed posts 47. The rotating plate 46 is located inside the fixed posts 47. A spring 48 is fixed inside the fixed posts 47. A guide plate 49 is fixed on the upper surface of the spring 48. A limit block 491 is fixed on the upper surface of the guide plate 49. The limit block 491 is located inside the rotating plate 46.
[0035] The fixed column 47 is used to support and install the second in-phase return bus 42 and the third in-phase return bus 43. The spring 48 is used to change the height of the guide plate 49. The guide plate 49 facilitates the change of the position of the limiting block 491. The limiting block 491 is used to fix the rotating plate 46 in the required position.
[0036] When it is necessary to connect the first in-phase return bus 41 and the second in-phase return bus 42 together, a downward pressing force is applied to the guide plate 49, the spring 48 is in a compressed state, and under the action of the connecting shaft 45, a rotational force is applied to the rotating plate 46. After the rotating plate 46 is rotated into the fixed post 47, the force applied to the guide plate 49 is released, and under the elastic force of the spring 48, the limiting block 491 springs back into the rotating plate 46. Using the above method, the second in-phase return bus 42 and the third in-phase return bus 43 can also be connected together.
[0037] Please see Figures 1-3 As shown, this embodiment, based on the above embodiment, also includes a limiting component 3. The limiting component 3 includes a limiting frame 31, a limiting post 32, a fixing plate 33, and a limiting rod 34. The limiting frame 31 is locked outside the first in-phase return bus 41, the second in-phase return bus 42, and the third in-phase return bus 43. The limiting post 32 is fixed to the lower surface of the limiting frame 31. The fixing plate 33 is fixed to the surface of the interlocking contactor 1. The limiting post 32 is connected through the interior of the fixing plate 33. The limiting rod 34 is connected through the interior of the limiting post 32 and the fixing plate 33.
[0038] The limiting frame 31 is used to protect the first in-phase return bus 41, the second in-phase return bus 42 and the third in-phase return bus 43 from the outside. The limiting post 32 is used to be inserted into the fixing plate 33, thereby fixing the limiting frame 31 in the required position. The limiting rod 34 is used to fix the limiting post 32 inside the fixing plate 33.
[0039] A guide rod 35 is fixed to the outer surface of the limit rod 34, and a connecting plate 36 is fixed to the surface of the interlocking contactor 1. The guide rod 35 passes through and is connected to the inside of the connecting plate 36.
[0040] The guide rod 35 is used to change the position of the limit rod 34, and the connecting plate 36 is used for the guide rod 35 to move inside it.
[0041] The connecting plate 36 and the guide rod 35 are internally threaded with a threaded post 37, and a guide block 38 is fixed on the upper surface of the threaded post 37.
[0042] The threaded post 37 is used to fix the guide rod 35 in the desired position, while the guide block 38 facilitates the application of rotational force to the threaded post 37.
[0043] Working principle: When it is necessary to fix the limit frame 31 on the surface of the interlocking contactor 1, insert the limit post 32 into the inside of the fixing plate 33, then apply a pushing force to the guide rod 35, insert the limit rod 34 into the limit post 32 and the fixing plate 33, apply a rotating force to the guide block 38, and rotate the threaded post 37 into the inside of the guide rod 35.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
