Description

Technical Field

[0001] The present application relates to the field of electronic components, and in particular to an ultrasonically welded fisheye terminal. Background Art

[0002] Ultrasonic welding uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the two surfaces of the objects rub against each other to form a fusion between the molecular layers.

[0003] In the related art, the fisheye terminal usually includes a terminal body, a fisheye integrally formed with one end of the terminal body, and a welding end integrally formed with the terminal body away from the fisheye. When in use, the welding end needs to be soldered and fixed on the bottom plate of the module, and then connected to other female ends through the fisheye.

[0004] It is found in actual use that when the above-mentioned fisheye terminal is installed, soldering is required. During the soldering process, the welding end and the point to be soldered need to be heated, and then the tin is melted at the connection position between the terminal and the module base plate, so that the fisheye terminal can be connected to the module base plate after the tin solidifies. The welding process is relatively complicated. Summary of the invention

[0005] In order to reduce the difficulty of assembling a fisheye terminal, the present application provides an ultrasonically welded fisheye terminal.

[0006] The ultrasonic welding fisheye terminal provided in this application adopts the following technical solution:

[0007] An ultrasonically welded fisheye terminal comprises a terminal body and a base arranged at one end of the terminal body, wherein an ultrasonic welding layer is arranged on the base.

[0008] By adopting the above technical solution, an ultrasonic welding layer is set on the base. During assembly, it is only necessary to fit the ultrasonic welding layer on the base to the part to be connected, and then the two can be welded together by ultrasonic welding. The overall process is simple and welding is convenient.

[0009] Optionally, the terminal body includes a substrate and a first fisheye and a second fisheye symmetrically arranged at both ends of the substrate, the substrate is folded in half to overlap the first fisheye and the second fisheye, the first fisheye and the second fisheye are combined into a fisheye structure, and the base is arranged at one end of the substrate away from the first fisheye and the second fisheye.

[0010] By adopting the above technical solution, a symmetrical first fisheye and a second fisheye are arranged on the substrate, and the first fisheye and the second fisheye are overlapped to form a fisheye structure by folding the substrate, which can effectively improve the overall structural strength.

[0012] By adopting the above technical solution, a buffer plate and a support plate are set. When the fisheye structure is crimped with the female end to be connected, the buffer plate will produce elastic deformation to buffer the whole. After the buffer gap is compressed, the support plate will support the whole to prevent the buffer plate from excessive deformation and causing failure.

[0013] Optionally, a groove is formed on a side of the connecting plate away from the supporting plate, and the ultrasonic welding layer is fixed in the groove.

[0014] By adopting the above technical solution, an ultrasonic welding layer is embedded on the connecting plate, so that the connecting plate can be conveniently connected by ultrasonic welding.

[0016] Optionally, an elastic groove is formed through the buffer plate.

[0017] By adopting the above technical solution, during processing, the elastic force of the buffer plate can be adjusted by controlling the size of the elastic groove, so that it can be suitable for different occasions.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. By setting an ultrasonic welding layer on the base, during assembly, it is only necessary to fit the ultrasonic welding layer on the base to the part to be connected, and then the two can be welded together by ultrasonic welding. The overall process is simple and the welding is convenient;

[0025] The following is combined with Figure 1-2 This application is described in further detail.

[0026] The present application embodiment discloses an ultrasonically welded fisheye terminal, referring to Figure 1 , including a terminal body 1 and a base 2 arranged at one end of the terminal body 1, an ultrasonic welding layer 3 is arranged on the base 2, and during installation, the base 2 is connected to the module bottom plate to be connected by ultrasonic welding.

[0027] The terminal body 1 includes a rectangular substrate 11 and a first fisheye 12 and a second fisheye 13 integrally formed at both ends of the same side of the substrate 11. The substrate 11 is folded along the symmetry line of the first fisheye 12 and the second fisheye 13 so that the first fisheye 12 and the second fisheye 13 overlap to form a fisheye structure, which can effectively improve the strength of the fisheye structure.

[0028] The base 2 includes a support plate 21, a buffer plate 22 and a connecting plate 23. The support plate 21 is integrally formed on the side of the substrate 11 away from the first fisheye 12, and the support plate 21 and the first fisheye 12 are in the same straight line. The buffer plate 22 is an elastic plate body with a C-shaped profile. The buffer plate 22 is integrally formed on the side of the substrate 11 away from the second fisheye 13, and the buffer plate 22 is aligned with the support plate 21. The connecting plate 23 is integrally formed with the end of the buffer plate 22 away from the substrate 11. The connecting plate 23 is located on the side of the support plate 21 away from the substrate 11 and is perpendicular to the support plate 21. A buffer gap 4 is formed between the connecting plate 23 and the support plate 21. When the fisheye structure is crimped and connected to the female end to be connected, the buffer plate 22 will produce elastic deformation to buffer the whole. After the buffer gap 4 is compressed, the support plate 21 will support the whole, so that the fisheye structure can be inserted into the female end, and the support plate 21 can effectively prevent the buffer plate 22 from being excessively bent and causing failure.

[0029] An embedding groove 231 is provided on one side of the connecting plate 23 away from the supporting plate 21 . The ultrasonic welding layer 3 can be set as an aluminum metal layer, a tin metal layer, a nickel metal layer, etc., and is ultrasonically welded to be embedded and fixed in the embedding groove 231 .

[0030] An elastic groove 221 is formed through the buffer plate 22, and the elastic groove 221 is formed in a direction parallel to the length of the support plate 21. In different usage scenarios, the elasticity required of the buffer plate 22 is also different, and the elasticity of the buffer plate 22 can be adjusted by changing the groove width of the elastic groove 221, which is convenient for processing.

[0031] The implementation principle of an ultrasonically welded fisheye terminal disclosed in an embodiment of the present application is: by embedding an ultrasonic welding layer 3 on a connecting plate 23, when welding the terminal to the bottom plate of the module, it is only necessary to adhere the ultrasonic welding layer 3 on the connecting plate 23 to the installation position, and then weld it through ultrasonic welding equipment, so that the terminal can be connected to the bottom plate of the module, and the welding method is simpler and more convenient.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
