[0003] Since sheet metal parts are bent structures, their strength is low. The existing transportation method is to transport sheet metal parts in bags, with hundreds or thousands of static contacts contained in one bag. Due to extrusion or other reasons, static contacts are easily deformed, affecting subsequent assembly and normal use of products. Utility Model Content

[0039] Example 1

[0040] This embodiment provides a contact structure of a contactor, as shown in the attached Figure 1-6 As shown, including:

[0041] The body 10 is integrally formed. First, the body 10 is made of a metal conductive material. The body 10 can be made of a suitable material according to actual needs, such as copper. The body 10 is integrally formed and can be machined or die-cast.

[0042] The body 10 comprises:

[0043] The connecting part 11 has a positioning protrusion 111 on the top surface thereof that matches the silver contact 12 . The silver contact 12 fits with the positioning protrusion 111 to form a positioning and fixing effect. Then, the silver contact 12 is connected and fixed to the connecting part 11 by welding.

[0044] The fixing part 13 is connected to the connecting part 11, and the bottom surface of the fixing part 13 and the bottom surface of the connecting part 11 are coplanar. The height of the fixing part 13 is lower than the height of the connecting part 11, that is, the top surface of the fixing part 13 is lower than the bottom surface of the connecting part 11, so the fixing part 13 is connected to the connecting part 11 to form the main body 10. In this embodiment, the main body 10 is similar to an L-shaped structure, that is, a step structure is formed. The fixing part 13 is provided with a fixing groove 131, and the fixing groove 131 is used to cooperate with other conductive parts. Here, the bolt passes through the fixing groove 131 to connect and fix with other conductive parts, so as to achieve the electrical connection effect between the main body 10 and the conductive part. In this embodiment, the conductive part can be a conductive bar. It should also be noted that when the bolt cooperates with the fixing part 13, the top surface of the bolt is lower than the top surface of the silver contact 12. First, the contact is an integral structure through the one-piece molding, and the contact is not easily deformed. Secondly, the positioning protrusion 111 is set to position the welding position between the silver contact 12 and the connecting part 11, which is convenient for welding accuracy. Finally, the electrical connection with the remaining conductive parts is achieved through the fixing part 13, and the height is limited so that after the bolt passes through the fixing groove 131 and is fixed to the conductive part, the head of the bolt will not be higher than the silver contact 12, preventing the bolt from affecting the electrical connection. Moreover, the overall structure can improve the current resistance level of the contact and reduce the effect of temperature rise.

[0045] Specifically, as attached Figure 1-6 As shown, the side where the positioning protrusion 111 cooperates with the silver contact 12 is an arc surface. Here, the arc surface is an inwardly concave arc surface. The arc surface is set so that the silver contact 12 can better cooperate with the positioning protrusion 111 to form a positioning and fixing effect. Here, the side where the silver contact 12 cooperates with the positioning protrusion 111 is also set as an arc surface, and the two arc surfaces fit together to form a center positioning and fixing effect. In addition, the positioning effect can also be achieved through a concave structure or through multiple convex points.

[0046] Specifically, the fixing groove 131 is in the shape of an elongated strip. The elongated strip allows the position of the bolt to be adjusted according to actual conditions during the fixing process, thereby satisfying the connection and fixing effects at different angles and reducing the difficulty of processing.

[0047] Specifically, as attached Figure 1-6 As shown, the fixing groove 131 extends toward the side away from the connecting portion 11, and the fixing groove 131 penetrates the side of the fixing portion 13. Here, the fixing groove 131 forms a U-shaped structure and opens toward the side away from the connecting portion 11. The fixing groove 131 is set through, which further reduces the difficulty of processing and is more convenient during the installation and fixing process.

[0048] Specifically, as attached Figure 1-5As shown, the top surface of the connecting portion 11 is provided with a boss 112, and the positioning protrusion 111 is located on the boss 112. The setting of the boss 112 has the effect of raising the silver contact 12. In addition, the boss 112 can be omitted, and the positioning protrusion 111 can be directly set on the top surface of the connecting portion 11 to achieve the positioning and fixing effect, and only the height difference between the connecting portion 11 and the fixing portion 13 needs to be considered.

[0049] Specifically, as attached Figure 2 As shown, a positioning hole 101 is provided on the bottom surface of the body 10. The positioning hole 101 is used for the positioning and fixing effect between the body 10 and the contactor, that is, the contactor is provided with a positioning column that cooperates with the positioning hole 101, and the positioning column is inserted into the positioning hole 101 to form a positioning and fixing effect. The size and size of the positioning hole 101 here can be adjusted according to actual needs. The positioning hole 101 can be located on the connecting part 11, and the positioning hole 101 can also be located on the fixing part 13.

[0050] Specifically, as attached Figure 2 As shown, the positioning hole 101 is located on the bottom surface of the connecting portion 11. Since the height of the connecting portion 11 is greater than the height of the fixing portion 13, the positioning hole 101 can increase the contact area. It should be noted here that the positioning hole 101 does not penetrate the top surface of the connecting portion 11. In addition, when the positioning hole 101 is located on the fixing portion 13, the positioning hole 101 can penetrate the fixing portion 13 in the vertical direction.

[0051] Specifically, as attached Figure 1-4 As shown in FIG. 6 , a chamfer 113 is provided on one side of the connecting portion 11 away from the fixing portion 13. The setting of the chamfer 113 saves materials, and the size of the chamfer 113 can be adjusted according to actual needs. The chamfer 113 is an inclined surface or a curved surface.

[0052] Specifically, as attached Figure 1-2 As shown, the top surface of the silver contact 12 is higher than the top surface of the positioning protrusion 111, so as to prevent the positioning protrusion 111 from affecting the cooperation between the silver contact 12 and the moving contact.

[0053] Specifically, the body 10 is machined and cut. The raw material is a profile, which is machined and cut into an L-shaped shape, and then the fixing groove 131 and other structures are formed by punching or stamping. The machining and cutting molding makes the overall surface smooth and flat, easy to process, and highly aesthetic. Moreover, the body 10 is machined as a whole, so the overall current resistance level is higher, the overall heat dissipation effect is better, and the temperature rise can be reduced.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled 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 methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
