Description

Technical Field

[0001] The utility model relates to the technical field of electricity, and particularly relates to a contact support of a contactor. Background Art

[0002] When an AC contactor operates, the contact support makes reciprocating motions back and forth for a long time. During the reciprocating motion, friction will occur between the contact support and the base. The existing contact supports generally adopt thermosetting materials. The thermosetting materials have excellent electrical properties, but their disadvantage is poor strength; the base generally adopts nylon PA66. The friction coefficient is large when the two materials move relative to each other. During the friction process, due to its own characteristics, the thermosetting material will generate a large amount of powder. The powder enters the electromagnetic system and the contact surface, affecting the product's suction and make-and-break, and the size of the thermosetting material changes after friction, affecting the product's fit, and further affecting the product's performance.

[0003] Those skilled in the art also splice and combine two different materials (thermosetting material and thermoplastic material) to form a contact support. However, they use screws to connect and fix the two materials. Due to the poor strength of the thermosetting material, the screw is prone to slipping when cooperating with the thermosetting material, resulting in the separation of the bolt from the thermosetting material, seriously affecting the overall movement of the contact support, and thus also affecting the product's suction and make-and-break. Content of the Utility Model

[0037] Embodiment 1

[0038] This embodiment provides a contact support of a contactor, as shown in the attached Figures 1-3 figure, including:

[0039] An insulating part 11, specifically referring to a position with excellent electrical performance, that is, a position with good electrical insulation performance.

[0040] A wear-resistant part 12, as the name implies, is a position with wear-resistant effect. The strength of the wear-resistant part 12 is greater than that of the insulating part 11. Here, the strength specifically refers to the wear resistance performance, that is, high strength means high hardness, and the corresponding wear resistance performance is better. The wear-resistant part 12 and the insulating part 11 are integrally formed. Here, the integral formation is specifically integral processing and forming, rather than forming a whole like a bolt fixation. Instead, after processing and production, the contact support is directly formed.

[0041] Firstly, through the setting of the insulating part 11, the electrical performance of the entire contact support is improved. The setting of the wear-resistant part 12 forms a wear-resistant effect. When the contact support cooperates with the base, through the mutual cooperation of the wear-resistant part 12 and the base, a large amount of powder generated by friction is prevented. Through the integral molding setting, the wear-resistant part 12 and the insulating part 11 are firmly fixed and will not fall off. Moreover, the processing is simple and no subsequent operations are required, thus also achieving the effect of reducing costs.

[0042] Specifically, as shown in the appendix Figures 1-3 As shown, there are two wear-resistant parts 12. The two wear-resistant parts 12 are located on both sides of the insulating part 11. In this embodiment, the two wear-resistant parts 12 are respectively located on the left and right sides of the insulating part 11, and the two wear-resistant parts 12 are respectively connected to the two side surfaces of the insulating part 11. The number of the wear-resistant parts 12 can be adjusted according to actual needs to achieve the cooperation with the insulating part 11. In addition, the wear-resistant part 12 can also be one, the wear-resistant part 12 can be three, or even four. Since the internal structures of contactors of different models are different, the number of the wear-resistant parts 12 can also be matched with the insulating part 11 according to actual needs to form a connection effect between them. Here, the cooperation position between the entire contact support and the base needs to be considered.

[0043] Specifically, as shown in the appendix Figures 1-3 As shown, one of the insulating part 11 and the wear-resistant part 12 is provided with a stepped groove 13, and the other of the insulating part 11 and the wear-resistant part 12 is provided with a stepped protrusion 14 that cooperates with the stepped groove 13. The cooperation of the stepped groove 13 and the stepped protrusion 14 improves the fixing strength. When the insulating part 11 is provided with the stepped groove 13, the wear-resistant part 12 is provided with the stepped protrusion 14; conversely, when the insulating part 11 is provided with the stepped protrusion 14, the wear-resistant part 12 is provided with the stepped groove 13. In this embodiment, the insulating part 11 is provided with the stepped groove 13. The stepped groove 13 is arranged on the left and right sides of the insulating part 11, that is, both side surfaces of the insulating part 11 are provided with the stepped groove 13. The wear-resistant part 12 is of an L-shaped structure, and the wear-resistant part 12 forms a stepped protrusion 14. The stepped protrusion 14 is the horizontal area of the L shape. The stepped protrusion 14 cooperates with the stepped groove 13 to form a limit fixation in one direction and prevent falling off.

[0044] Specifically, as shown in the appendix Figures 1-3As shown, one of the insulating part 11 and the wear-resistant part 12 is provided with a first fixing groove 15, and the other of the insulating part 11 and the wear-resistant part 12 is provided with a first fixing block 16 that cooperates with the stepped groove 13. The cooperation between the first fixing groove 15 and the first fixing block 16 forms a further cooperation effect. When the insulating part 11 is provided with the first fixing groove 15, the wear-resistant part 12 is provided with the first fixing block 16; conversely, when the insulating part 11 is provided with the first fixing block 16, the wear-resistant part 12 is provided with the first fixing groove 15. In this embodiment, the side surface of the insulating part 11 is provided with the first fixing block 16, and the wear-resistant part 12 is provided with the first fixing groove 15. Here, the first fixing groove 15 is located in the longitudinal region of the L shape.

[0045] Specifically, as shown in the appendix Figures 1-3 As shown, the first fixing groove 15 is a dovetail groove. The setting of the dovetail groove forms an anti-detachment effect. When the first fixing groove 15 is a dovetail groove, the first fixing block 16 is also a dovetail structure. In addition, the connection strength between the two can also be increased through a barbed structure, or the connection strength can be improved by setting a plurality of grooves to increase the contact area between the insulating part 11 and the wear-resistant part 12.

[0046] Specifically, as shown in the appendix Figures 1-3 As shown, the first fixing groove 15 is provided with a positioning hole 151, and the first fixing block 16 is provided with a positioning post 161. The positioning post 161 cooperates with the positioning hole 151. Here, the number of the positioning hole 151 and the positioning post 161 can be adjusted according to actual needs. In this embodiment, the insulating part 11 and the wear-resistant part 12 can form a locking effect in three directions of X, Y, and Z. Those skilled in the art can also adjust the locking direction according to actual needs to improve the cooperation strength between the two.

[0047] Specifically, the insulating part 11 is made of a thermosetting material, and the wear-resistant part 12 is made of a thermoplastic material. Here, the thermosetting material and the thermoplastic material are well-known materials to those skilled in the art, so the corresponding models are not listed one by one in this embodiment. Here, the entire contact support is made of plastic.

[0048] Specifically, the insulating part 11 and the wear-resistant part 12 are formed by two-color injection molding. In a set of molds, injection of one material is carried out first. After molding, injection of the other material is carried out, so that the contact support is directly produced in a set of molds. For example, in a set of molds, injection of a thermosetting material is carried out first to form the insulating part 11. When the insulating part 11 is molded, injection of a thermoplastic material is carried out, so that the wear-resistant part 12 is formed on the side of the insulating part 11. When the whole is molded, the mold is opened, and the contact support can be directly processed and formed. Or, the insulating part 11 and the wear-resistant part 12 are formed by insert secondary injection molding. A set of molds processes and forms a structure of one material, and then the processed material structure is placed into another set of molds, and then the contact support is processed and formed in the other set of molds. For example, the insulating part 11 is processed and formed in a set of molds first, and then the insulating part 11 is placed into another set of molds, and the wear-resistant part 12 is processed in this mold. When the processed wear-resistant part 12 is directly connected to the insulating part 11, the effect of integral processing is formed, and the contact support is obtained when the mold is opened.

[0049] Embodiment 2

[0050] This embodiment provides a contact support of a contactor. As shown in the appendix Figures 4-6 The difference between Embodiment 2 and Embodiment 1 is that there is one wear-resistant part 12, and the wear-resistant part 12 is located on one side of the insulating part 11. The number of the wear-resistant parts 12 is adjusted according to actual needs. The contact support in this embodiment has a different structure from that in Embodiment 1 and is used in a different environment. The contact support in this embodiment needs to cooperate with the iron core. Specifically, here the wear-resistant part 12 cooperates with the iron core, that is, one side of the wear-resistant part 12 is connected and fixed to the insulating part 11, and the other side of the wear-resistant part 12 cooperates with the iron core. Therefore, an installation groove 121 for cooperating with the iron core is provided on one side of the wear-resistant part 12.

[0051] Specifically, as shown in the appendix Figures 4-6As shown, the wear-resistant part 12 is provided with a second fixing block 17 and a fixing column 18. The second fixing block 17 is connected to the fixing column 18. Here, the second fixing block 17 and the fixing column 18 are connected to form a T-shaped structure. The other end of the fixing column 18 is connected and fixed to the rest of the wear-resistant part 12. The insulating part 11 is provided with a second fixing groove 19 and a fixing hole 20. The second fixing groove 19 communicates with the fixing hole 20. The second fixing block 17 cooperates with the second fixing groove 19, and the fixing column 18 passes through the fixing hole 20. It should be noted here that the second fixing block 17 is formed and embedded into the second fixing groove 19 during the processing, and the fixing column 18 is also formed and embedded into the fixing hole 20 during the processing. When disassembly is required, since the size of the fixing hole 20 is smaller than the size of the second fixing block 17, disassembly cannot be carried out; when the second fixing block 17 is disassembled, since the fixing column 18 and the fixing hole 20 cooperate to form a limit in the horizontal direction, disassembly cannot be carried out either, that is, limits in the X, Y, and Z axis directions are formed. Alternatively, the insulating part 11 is provided with a second fixing block 17 and a fixing column 18, and the second fixing block 17 is connected to the fixing column 18; the wear-resistant part 12 is provided with a second fixing groove 19 and a fixing hole 20, the second fixing groove 19 communicates with the fixing hole 20, the second fixing block 17 cooperates with the second fixing groove 19, and the fixing column 18 passes through the fixing hole 20. The second fixing block 17 and the fixing column 18 cooperate to form a T-shaped structure. When the wear-resistant part 12 and the insulating part 11 are fitted together, an anti-detachment effect is also formed. In addition, the connection strength between the two can also be increased through a barbed structure, or by providing a number of grooves to increase the contact area between the insulating part 11 and the wear-resistant part 12 and improve the connection strength.

[0052] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
