In view of the shortcomings of the prior art, the present invention provides a connecting plate for a contactor. The connecting plate is stably connected to the contactor and is not prone to loosening or movement.
[0025] In order to achieve the above-mentioned purpose, the present invention provides a connecting plate for a contactor, comprising a first connecting end 1 for connecting with a static contact and a second connecting end 2 for wiring, a plurality of through holes 3 for connecting with bolts are distributed between the first connecting end 1 and the second connecting end 2, an L-shaped notch 5 for supporting and limiting with a pillow block 4 of the contactor housing is formed between the first connecting end 1 and the second connecting end 2, the L-shaped notch 5 comprises two adjacent side walls, the two adjacent side walls are in contact with the top surface and the side surface of the pillow block 4 respectively, the first connecting end 1 and the second connecting end 2 are provided to make the connection more stable, the first connecting end 1 and the second connecting end 2 can respectively connect different The position of the contactor can meet different needs in the contactor. Several through holes 3 are set between the first connecting end 1 and the second connecting end 2 to make the connection between the connecting plate and the contactor more stable. Bolt connection is adopted, and the connection method is simple. The L-shaped notch 5 formed between the first connecting end 1 and the second connecting end 2 can be connected with the pillow block 4 of the contactor. The pillow block 4 is a structure on the contactor that can be used to fix and limit the connecting plate. The two adjacent side walls of the L-shaped notch 5 are in contact with the top and side surfaces of the pillow block 4 respectively, which can make the positioning stability between the connecting plate and the pillow block 4 better and more convenient to install. The top of the first connecting end 1 has a joint surface 6 that is welded and fixed with the static contact. The end of the first connecting end 1 has a joint surface 6 that is welded and fixed with the static contact. The upper portion has an arc-shaped profile. Since the static contact needs to be welded to the connecting plate, the joint surface 6 is provided so that the connecting plate is not easily damaged during welding. The arc-shaped profile of the first connecting end 1 can adapt to the outer peripheral shape of the static contact, avoiding the shape mismatch between the static contact and the connecting plate after welding, with better adaptability and more stable connection. One side wall of the L-shaped notch 5 is integrally formed with an insert block 7 that cooperates with the groove 41 of the pillow block 4 of the contactor housing for plugging and positioning. The insert block 7 is provided on the L-shaped side wall. After the connecting plate is connected to the contactor, the insert block 7 can be plugged and matched with the groove 41 of the pillow block 4, making the connection between the connecting plate and the contactor more stable. The insert block 7 is integrally formed with the side wall of the L-shaped notch 5, making it easier to manufacture. More convenient and saves manufacturing cost; the first connecting end 1 and the second connecting end 2 are integrally formed, and the two adjacent side walls of the L-shaped notch 5 are perpendicular to each other. The first connecting end 1 and the second connecting end 2 are integrally formed, which is more convenient to manufacture and has low manufacturing cost. The two adjacent side walls of the L-shaped notch 5 are perpendicular to each other, which can make the L-shaped notch 5 more adaptable to the side wall of the pillow block 4. The vertically arranged L-shaped notch 5 has higher strength and better stability; the connecting plate is formed by bending a strip of metal plate, and the two ends of the metal plate respectively constitute the first connecting end 1 and the second connecting end 2. The L-shaped notch 5 is formed at the bend. The connecting plate formed by metal plate processing has higher strength and is more convenient to process;The first connecting plate 8 and the second connecting plate 9 are detachably connected. One end of the first connecting plate 8 constitutes the first connecting end 1, and the other end of the first connecting plate 8 and the one end of the second connecting plate 9 are stacked and connected. The other end of the second connecting plate 9 constitutes the second connecting end 2. The detachable first connecting plate 8 and the second connecting plate 9 are more convenient to disassemble and replace. Since the connection between the connecting plate and the pillow block 4 will pass through the current, the current will easily cause loss to the first connecting plate 8 after long-term use. At this time, those skilled in the art can save costs by replacing the first connecting plate 8 separately. The stacked first connecting plate 8 and the second connecting plate 9 have higher strength and the stacked arrangement takes up less space. The structure of the connecting plate is made more compact, and the working efficiency of the connecting plate is improved; the stacking connection of the first connecting plate 8 and the second connecting plate 9 is aligned with the through hole 3. The through hole 3 is provided at the stacking connection to make the length of the through hole 3 longer. The through hole 3 passes through the connecting plate. The through hole 3 is used to connect the connecting plate to the contactor, and the connection stability is higher and it is not easy to loosen; a pipe portion 10 is extended from the lower part of one end of the second connecting plate 9, and the through hole 3 passes through the pipe portion 10. The pipe portion 10 is used to cooperate with the mounting hole of the contactor housing for insertion and positioning. The pipe portion 10 extending from the lower part of the second connecting plate 9 and passing through the through hole 3 is adopted. The pipe portion 10 can increase the length of the through hole 3, making the bolt connection more stable;
[0026] In the first embodiment of the present solution, the connecting plate is an integrally formed connecting plate, that is, the first connecting end 1 and the second connecting end 2 are integrally formed, and the L-shaped notch 5, that is, the connection between the first connecting end 1 and the second connecting end 2, is vertically arranged. When installing the connecting plate, those skilled in the art place the L-shaped notch 5 corresponding to the pillow block 4 of the contactor, and one side of the L-shaped notch 5 abuts against the top surface of the pillow block 4, and the other side abuts against the side surface of the pillow block 4 so that the connecting plate can cooperate with the pillow block 4 to limit the position, and then the connecting plate and the contactor are fixed by bolts. The connection method is simple and not easy to loosen. When the connecting plate needs to be replaced, the entire connecting plate can be directly replaced. The integrally formed connecting plate is more convenient to manufacture and has low cost.
[0027] In the second embodiment of the present scheme, the connecting plate is a split type, that is, a first connecting plate 8 and a second connecting plate 9 are stacked together to form a combination, the first connecting end 1 of the first connecting plate 8 is in contact with the pillow block 4, the second connecting plate 9 is fixedly connected to the mounting hole of the contactor, and the first connecting plate 8 and the second connecting plate 9 are fixed by bolts through the through hole 3. When a technician in this field installs the connecting plate, the first connecting end 1 can be placed corresponding to the pillow block 4 first, and then the through hole 3 of the second connecting plate 9 can be placed corresponding to the mounting hole of the contactor. Thereafter, the bolts are passed through the through holes 3 of the first connecting plate 8 and the second connecting plate 9 to be fixedly connected to the mounting holes. The connection method is simple and the connection stability is higher. When the connecting plate is damaged and needs to be replaced, the damaged part, that is, the first connecting plate 8 or the second connecting plate 9, can be replaced, saving costs.
