Description

Technical Field

[0001] This application relates to a dustproof terminal structure. Background Technology

[0002] With the rapid development of the electronics industry and the expansion of the market, electrical systems are becoming increasingly sophisticated, and various electrical appliances with different characteristics are constantly emerging. This places increasingly higher demands on the electrical performance of wire harnesses, and connection terminals play a crucial role in wire harnesses and the entire electrical system. If we compare a wire harness to the nervous system of an entire device, then the terminals are the connecting points of these nervous systems. Therefore, the quality of wire harness terminals directly affects whether the wire harness can function properly.

[0003] Relevant prior art can be found in Chinese Utility Model Patent CN216563616U, which discloses a female terminal for a wire harness, including a fully enclosed terminal head and an integrated wire harness fixing part connected to one end of the fully enclosed terminal head. The fully enclosed terminal head includes a fully enclosed outer shell, an inner bending part, a spring contact, and a guide plate. The fully enclosed outer shell is a square tube formed by bending and splicing a base plate. This female terminal is designed with an integral fully enclosed structure, which is stronger and more stable in overall fastening. The contact spring contact is not visible to the outside, so it will not be deformed by impact. Furthermore, when the male and female terminals are inserted, the four-way guide structure and vibration damping can achieve all-directional protection after the terminal is inserted.

[0004] However, in this prior art, the full-coverage housing of the female wire harness terminal is open at both ends along the axial direction, and one end of the full-coverage housing needs to be connected to the male terminal. The other end of the full-coverage housing is also open, which makes it easy for dust to accumulate during use and enter the cavity of the full-coverage housing, ultimately affecting the effective electrical contact between the female and male wire harness terminals and causing contact failure. This is especially problematic when the aforementioned female wire harness terminal is used in high-vibration and harsh environments such as automobiles.

[0005] Therefore, it is necessary to design a terminal structure that can achieve a dustproof effect. Utility Model Content

[0006] The purpose of this application is to provide a dustproof terminal structure that can achieve a dustproof effect.

[0017] Furthermore, multiple groove structures or rib structures are formed on the inner wall surface of the docking cavity of the cylindrical main body, and the groove structures or rib structures extend circumferentially along the cylindrical main body and are spaced apart axially along the cylindrical main body.

[0018] Furthermore, the connecting seam extends along the cylindrical wall of the main body in a non-linear manner;

[0023] The first joint segment and the second joint segment are offset from each other along the circumference of the cylindrical main body.

[0024] The third joint segment connects the first joint segment and the second joint segment.

[0025] Furthermore, the middle position of the connector along the circumferential direction of the cylindrical main body is aligned with the first joint segment along the axial direction of the cylindrical main body.

[0026] Furthermore, along the axial direction of the cylindrical main body, the extension length of the first joint segment is greater than the extension length of the second joint segment;

[0027] The cylindrical main body is joined and fixed to at least one of the first joint segment, the second joint segment, and the third joint segment via a dovetail groove structure, and / or

[0035] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] Please refer to Figures 1 to 5As shown, this application discloses a dustproof terminal structure. This dustproof terminal structure is formed by stamping and bending a metal plate, resulting in a simple manufacturing process, low cost, good structural stability, and a certain degree of dustproof effect. Specifically, the dustproof terminal structure includes a cylindrical main body 1, a mating tail wing 2, and a closed cover 3. The cylindrical main body 1 is formed by rolling a metal plate and has a connecting seam 10. The cylindrical main body 1 is hollow, forming a mating cavity 11, and has a mating interface 12 at one end that communicates with the outside. The mating interface 12 is for inserting a mating module, such as a mating terminal (not shown) that mates with the dustproof terminal structure.

[0037] The docking tail fin 2 is integrally connected to the end of the cylindrical main body 1 away from the docking interface 12. The docking tail fin 2 includes a docking fin 21 and a connecting portion 22 that integrally connects the docking fin 21 to the cylindrical main body 1. The docking fin 21 includes a fin body 211 and a plurality of locking fins 212 extending outward from both sides of the fin body 211. In actual use, the docking fins 21 can be used to connect to a wire harness, for example, the wire harness can be supported above the fin body 211, and the locking fins 212 can be bent upward and wound and fastened to the outer periphery of the wire harness by a riveting machine to achieve fixation. Of course, the wire harness can also be other components, such as columnar metal pins, etc.

[0038] Please refer to the reference. Figures 1 to 5 As shown, the sealing cover 3 seals the end of the cylindrical main body 1 away from the interface 12, and a connector 31 integrally connects the edge of the cylindrical wall of the end of the cylindrical main body 1 away from the interface 12 to the edge of the sealing cover 3. In this embodiment, preferably, the cylindrical main body 1, the connector 31 and the sealing cover 3 are formed from the same metal plate by stamping and bending.

[0039] More specifically, the cylindrical main body 1 is cylindrical, and the connecting seam 10 and the connecting part 22 are located at opposite ends in the radial direction of the cylindrical main body 1. To ensure a more stable fixation between the sealing cover 3 and the cylindrical main body 1, and to improve the sealing and dustproof effect, a reinforcing part 32 extends from the end edge of the sealing cover 3 away from the connecting member 31 in the radial direction of the cylindrical main body 1. The reinforcing part 32 is fitted to the inner wall surface of the mating cavity 11 of the cylindrical main body 1. In a preferred embodiment, the reinforcing part 32 is fixed to the inner wall surface of the mating cavity 11 of the cylindrical main body 1 by welding. Furthermore, in a preferred embodiment, the sealing cover 3 covers the end edge of the cylindrical wall of the cylindrical main body 1 away from the mating interface 12, and the cylindrical main body 1 and the sealing cover 3 are stacked along the axial direction of the cylindrical main body 1. This makes it easy to process and easy to control the flatness of the closed cover 3. When the closed cover 3 is bent and assembled to close the opening of the cylindrical main body 1 away from the interface 12, the end edge of the cylindrical main body 1 away from the interface 12 can be used as the bending stop surface.

[0040] Please refer to Figure 5 As shown, in a preferred embodiment, a plurality of groove structures 110 or rib structures are formed on the inner wall surface of the docking cavity 11 of the cylindrical main body 1. The groove structures 110 or rib structures extend circumferentially along the cylindrical main body 1 and are spaced apart axially along the cylindrical main body 1. The groove structures 110 or rib structures are used to scrape the surface of the docking module when the docking module is inserted into the docking cavity 11 through the docking interface 12, thereby creating a scraping and dust removal effect. This improves the electrical connection stability between the dustproof terminal structure and the docking module, and also increases the friction between the docking module and the dustproof terminal structure. The groove structure 110 is preferred, as it can accommodate the scraped dust.

[0041] Please refer to the reference. Figure 1 and Figure 2 As shown in the preferred embodiment of this application, the connecting seam 10 formed on the cylindrical main body 1 extends along the cylindrical wall surface of the cylindrical main body 1 in a non-linear manner. Specifically, when the cylindrical main body 1 is unfolded into a flat plate, the extension path of the connecting seam 10 is non-linear. The connector 31 is formed on the edge of the cylindrical wall of the cylindrical main body 1 at the end away from the interface 12 and at a position adjacent to the connecting seam 10 along the circumference of the cylindrical main body 1.

[0042] In one embodiment, the connecting seam 10 includes a first seam segment 101 extending axially along the cylindrical body portion 1, a second seam segment 102 extending axially along the cylindrical body portion 1, and a third seam segment 103. The first seam segment 101 is located at the end of the cylindrical body portion 1 axially close to the interface 12. The second seam segment 102 is located at the end of the cylindrical body portion 1 axially away from the interface 12. The first seam segment 101 and the second seam segment 102 are offset circumferentially along the cylindrical body portion 1. The third seam segment 103 connects the first seam segment 101 and the second seam segment 102. Please refer to... Figure 2 As shown, in a preferred embodiment of this application, the connector 31 is aligned with the first joint segment 101 along the axial direction of the cylindrical main body 1 at its midpoint along the circumferential direction. This improves the structural strength of the cylindrical wall of the cylindrical main body 1 and reduces the impact of the connecting seam 10 on the structural strength of the cylindrical wall of the cylindrical main body 1.

[0043] In one embodiment, the third joint segment 103 extends in an arc shape along the circumference of the cylindrical main body 1, and the plane containing the extension path of the third joint segment 103 is perpendicular to the axial direction of the cylindrical main body 1. In other embodiments, the third joint segment 103 may also be designed to extend in a spiral shape from top to bottom along the circumference of the cylindrical main body 1. Preferably, along the axial direction of the cylindrical main body 1, the extension length of the first joint segment 101 is greater than the extension length of the second joint segment 102. In a preferred embodiment, the cylindrical main body 1 is joined and fixed to at least one of the first joint segment 101, the second joint segment 102, and the third joint segment 103 by a dovetail joint structure (not shown), and / or the cylindrical main body 1 is fixed to at least one of the first joint segment 101, the second joint segment 102, and the third joint segment 103 by welding.

[0044] It should be noted that the dustproof terminal structure of this application can be used alone or multiple of them can be installed into an electronic connector at the same time to be used as a complete connector.
