TECHNICAL FIELD

[0001] The utility model relates to terminal technical field, especially a kind of flat insertion type high current terminal. BACKGROUND

[0002] In the field of power transmission and connection, high current terminals, as key conductive connection components, are widely used in various electrical equipment, power systems and industrial control occasions. With the continuous improvement of the power of electrical equipment, higher requirements are put forward for the conductive performance, connection reliability and vibration resistance of high current terminals.

[0003] Traditional high current terminal design often faces the problem of insufficient connection stability, especially in high-vibration environments, the connection part is prone to looseness, leading to increased contact resistance, which in turn causes local overheating and even equipment failure or safety accidents. In addition, some traditional terminal designs have defects in terms of forward clamping force, making it difficult to maintain stable contact pressure during long-term use, affecting the conductive efficiency and stability of equipment operation.

[0004] To address the above problems, the industry is constantly exploring new terminal design methods to improve the connection reliability and vibration resistance of high current terminals. Among them, the flat insertion type connection method gradually attracts attention due to its compact structure, easy plugging and other advantages. However, the existing flat insertion type terminal design still needs to be improved in terms of forward clamping force and vibration resistance, and cannot meet the strict requirements for connection stability in high-power, high-vibration environments.

[0005] Therefore, the present application develops a flat insertion type high current terminal to solve the problems existing in the prior art. SUMMARY

[0014] Preferably, the angle of the first curved segments is smaller than the angle of the second curved segments, so that the second straight segments are closer to the inserting part relative to the first straight segments.

DETAILED DESCRIPTION

[0028] The content of the utility model will be described further in connection with specific embodiments:

[0029] As Figures 1-3 Indicated, a flat insertion type large current terminal, including two symmetrical limiting parts 1 that are arranged and inserting part 2, wherein two limiting parts 1 are fixedly connected through rivets at the same end, and form an insertion slot 11 between them, and the inserting part 2 is inserted in the insertion slot 11, and the two opposite sides of the inserting part 2 are respectively in close abutment with the inner side wall of the corresponding limiting part 1. And in this embodiment, the limiting part 1 is bent for many times, wherein the bending direction is towards the center line of the insertion slot 11, so that a clamping part 3 is formed, which is in close contact with the inserting part 2, and an interference fit is formed between them, that is, the clamping part 3 tightly clamps the inserting part 2 with a certain pressure, so as to ensure the stability and reliability of the connection.

[0030] In this embodiment, as Figures 4-5 As shown, the limiting part 1 includes multiple first limiting bodies 12 and multiple second limiting bodies 13, and the multiple first limiting bodies 12 and second limiting bodies 13 are alternately arranged along the extension direction of the slot 11. The clamping part 3 is also divided into two parts: one part is the first clamping position 31 located on the first limiting body 12, and the other part is the second clamping position 32 located on the second limiting body 13. The two clamping positions work together to provide a stable clamping effect for the insertion part 2. When the insertion operation is performed and the insertion part 2 is inserted into the slot 11, the side wall of the insertion part 2 will first contact the first clamping position 31, and then contact the second clamping position 32. Specifically, as the insertion part 2 continues to penetrate deeper into the slot 11, its side wall will first encounter the first clamping position 31 on the first limiting body 12. Under the compression and constraint of the first clamping position 31, it will continue to advance, and then it will come into contact with the second clamping position 32 on the second limiting body 13. The second clamping position 32 will further apply a clamping force to the insertion part 2. Through such sequential contact and clamping, the insertion part 2 can be firmly fixed in the slot 11, forming a reliable connection.

[0031] Specifically, such as Figure 2 As shown, the first limiting body 12 has a first curved section 121 and a first straight section 122, and the second limiting body 13 has a second curved section 131 and a second straight section 132. The first curved section 121 forms a first clamping position 31, and the second curved section 131 and the second straight section 132 together form a second clamping position 32. When the insertion part 2 is inserted, the first curved section 121 applies a clamping force to the insertion part 2 from one side, initially fixing and positioning the insertion part 2. At this time, the second curved section 131 is not in contact with the insertion part 2. As the insertion part 2 is inserted, the second curved section 131 and the second straight section 132 come into contact with the insertion part 2 and exert a clamping force on it, further enhancing the fixing effect on the insertion part 2.

[0032] Furthermore, such as Figure 3 As shown, the bending angle of the first bending segment 121 is different from that of the second bending segment 131. The angle formed by the first bending segment 121 is relatively small, so that one end of the first bending segment 121 connected to the first straight segment 122 is far away from the insertion part 2. In contrast, the angle of the second bending segment 131 is larger, so that one end of the second bending segment 131 connected to the second straight segment 132 is closer to the insertion part 2.

[0033] To provide a highly reliable connection in high-vibration environments, a fixing part 4 is fixedly provided on the side away from the insertion part 2 on the two limiting parts 1 by means of rivets. The fixing part 4 has multiple abutting parts 41, which abut against the outer surfaces of the first bending section 121 and the second bending section 131 respectively, thereby firmly fixing the limiting part 1 in a specific position and preventing the limiting part 1 from shifting or loosening during use.

[0034] Specifically, the contact portion 41 is in very close contact with the outer surface of the first limiting body 12, presenting a completely fitted state. This ensures that the shape and size of the contact portion 41 are adapted to the height of the outer surface of the first limiting body 12, providing stable and uniform support for the first limiting body 12. This helps the first limiting body 12 to better perform its clamping function and ensures a stable clamping state when in contact with the insertion part 2, thereby guaranteeing the stability of current transmission. There is a certain gap between the contact portion 41 and the second limiting body 13, with contact occurring only at the second curved section 131. The angle of the second curved section 131 is greater than that of the first curved section 121, and the second straight section 132 is closer to the insertion part 2. The contact portion 41 only contacts the curved section 121, which can, to a certain extent, fix and support the second limiting body 13, preventing excessive deformation or displacement under high vibration environments, and also avoids affecting the precise clamping of the insertion part 2 by the second straight section 132 due to excessive constraint. At the same time, a certain amount of elastic deformation space is reserved for the second limiting body 13, so that it can better adjust its clamping force and position when facing the insertion of the insertion part 2 and external vibration, so as to work together with the first limiting body 12 to achieve stable and reliable clamping of the insertion part 2.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
