Description

Technical Field

[0001] This application relates to the technical field of conductive components, and in particular to a connecting piece. Background Technology

[0002] With the continuous development of the electronics industry, the types of conductive components used for electrical connections between various electrical parts are becoming increasingly diverse. Connecting tabs, as one of the commonly used conductive components in the electronics industry, have advantages such as stable shape and good conductivity, and are widely used in electrical accessories such as charging boxes.

[0003] In related technologies, such as Figure 1 The disclosed diagram shows a connecting piece comprising a connecting piece body 1 with a connecting hole 3. When this connecting piece is used in a charging case, the connecting piece body 1 needs to be connected to other conductive pieces to enable current transmission within the charging case. To assemble the conductive pieces and the connecting piece body 1, one end of the conductive piece is first inserted into the connecting hole 3, and then solder is used to fill the space between the conductive piece and the hole wall of the connecting hole 3, thereby achieving welding between the conductive piece and the connecting piece body 1.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: when the conductive sheet is soldered to the connecting piece, after the conductive sheet is inserted into the connecting hole, the gap formed between the hole wall and the conductive sheet is small, making it difficult for the solder to penetrate into the gap during the soldering process. As a result, the connection stability between the conductive sheet and the connecting piece body is poor and needs to be improved. Summary of the Invention

[0005] To improve the connection stability between the conductive sheet and the connecting sheet body, this application provides a connecting sheet.

[0006] The connecting piece provided in this application adopts the following technical solution:

[0007] A connecting piece includes a connecting piece body, a connecting hole and a relief groove formed on the connecting piece body, the connecting hole being formed on the bottom wall of the relief groove; a mounting member detachably disposed on the connecting piece body passes through the connecting hole, the mounting member having a mounting hole for inserting a conductive piece; a receiving cavity is formed between the mounting member and the connecting piece body, the cavity wall having a feed hole for injecting solder from the outside and a guide hole for communicating with the mounting hole.

[0008] By adopting the above technical solution, when assembling the conductive sheet and the connecting sheet body, the mounting component is first inserted into the connecting hole and connected to the connecting sheet body. Then, the conductive sheet is inserted into the mounting hole, and then soldered onto the mounting component using tin soldering. During the soldering operation, the heated and molten solder first flows into the receiving cavity through the feed hole, and then flows into the gap between the conductive sheet and the mounting component along the guide hole, thereby achieving the soldering connection between the conductive sheet, the mounting component, and the connecting sheet body. This design not only makes it easier for the solder to flow between the conductive sheet and the connecting sheet body, but also allows the solder to remain in the receiving cavity and the guide hole after soldering, thereby increasing the connection area between the conductive sheet and the connecting sheet body and improving the connection stability of the two.

[0009] Furthermore, for some relatively large conductive sheets, the mounting hardware can be removed from the connecting sheet body, and the conductive sheet can be directly inserted into the connecting hole to solder it directly onto the connecting sheet body. Moreover, when connecting conductive sheets of different sizes, mounting hardware of different sizes can be connected to the connecting sheet body accordingly, thereby expanding the applicability of the connecting sheet and making it highly practical.

[0010] Optionally, the mounting component includes a hollow mounting ring and an extension ring integrally formed on the outer wall of the mounting ring. The mounting ring passes through the connecting hole, and the extension ring is located outside the connecting hole. The connecting piece body has an annular positioning groove, which is arranged around the outside of the clearance groove. The distance between the extension ring and the mounting ring is greater than the distance between the positioning groove and the connecting hole.

[0011] By adopting the above technical solution, when the mounting component is connected to the connecting piece body, the mounting ring passes through the connecting hole and the extension ring abuts against the side of the connecting piece body facing the opening of the relief groove. After the welding liquid is injected into the receiving cavity through the feed hole, the welding liquid is blocked by the extension ring and does not flow around easily, which helps to improve the welding strength between the conductive sheet and the connecting piece body.

[0012] If a gap exists between the extension ring and the connecting piece body due to factors such as uneven surface of the extension ring or improper installation, the welding liquid in the receiving cavity will flow into the positioning groove through the gap. The positioning groove serves two purposes: firstly, it collects the welding liquid, preventing it from spreading all over the surface of the connecting piece body and facilitating subsequent cleaning; secondly, the welding liquid remaining in the positioning groove can further connect the extension ring and the connecting piece body, thereby improving the connection strength between the mounting part and the connecting piece body.

[0013] Optionally, the mounting ring is made of a conductive material, and the length of the mounting ring is greater than the thickness of the connecting piece body.

[0014] By adopting the above technical solution, the conductive sheet has a large contact area with the mounting ring and a good conductivity when it is inserted into the mounting hole.

[0015] Optionally, the inner sidewall of the mounting ring is provided with anti-slip texture at both ends.

[0016] By adopting the above technical solution, the anti-slip texture increases the frictional resistance between the conductive sheet and the mounting ring, making it less likely for the conductive sheet to move relative to the mounting ring after it is inserted into the mounting hole, thus facilitating subsequent welding operations. Furthermore, since both ends of the mounting ring are equipped with anti-slip textures, the conductive sheet can contact the anti-slip textures and remain firmly in place regardless of which side of the mounting ring it enters from, resulting in excellent anti-slip performance.

[0017] Optionally, the sidewall of the mounting ring is stamped inward with a bent portion, the bent portion being located on the side of the guide hole away from the feed hole.

[0018] By adopting the above technical solution, during the process of the conductive sheet being inserted into the mounting hole, the bent part deforms under the pressure of the conductive sheet and generates elastic force. This elastic force drives the bent part to press tightly against the conductive sheet, thereby further improving the stability of the conductive sheet. In addition, after the solder flows into the gap between the mounting ring and the conductive sheet through the feed hole, the bent part also plays a certain role in preventing leakage, making it difficult for the solder to flow out from the opening on the side of the mounting ring away from the feed hole.

[0019] Optionally, a positioning ring is integrally formed on the side of the extension ring facing the connecting piece body. The positioning ring is inserted into the positioning groove, and a rubber ring capable of elastic deformation is provided on the groove wall of the positioning groove.

[0020] By adopting the above technical solution, after the mounting ring is inserted into the connecting hole, the operator can insert the positioning ring into the positioning groove to clamp the positioning ring by the deformation of the rubber ring, thereby realizing the connection between the mounting part and the connecting piece body. No screwdriver or other installation tools are needed during disassembly and assembly, making the operation simple.

[0021] Optionally, the extension ring has several positioning screw holes, and positioning bolts are threaded into the positioning screw holes. The diameter of the shank of the positioning bolt is smaller than the width of the positioning groove.

[0022] By adopting the above technical solution, after the mounting ring is inserted into the connecting hole, the operator can thread the positioning bolt into the positioning bolt hole, so that the shank of the positioning bolt abuts against the bottom wall of the positioning groove, and the head of the positioning bolt presses the extension ring onto the connecting piece body, thereby realizing the connection between the mounting part and the connecting piece body. The connection between the two has high strength and good stability.

[0023] Optionally, the connecting piece body includes a fixed part, a movable part located on one side of the fixed part, and an adjustment part disposed on the side of the fixed part facing the movable part. The movable part has an adjustment groove on its side facing the fixed part, and the adjustment part is slidably disposed in the adjustment groove.

[0024] By adopting the above technical solution, the connecting piece body is installed in front of electrical accessories such as charging boxes. The operator can slide the adjustment part along the adjustment groove to change the overall length of the connecting piece body, thereby adapting to electrical accessories of different sizes, which is highly practical.

[0025] Optionally, the side wall of the adjustment part is provided with an elastic locking block, and the groove wall of the adjustment groove is provided with a plurality of locking slots that engage with the locking block, and the plurality of locking slots are equidistantly distributed along the extension direction of the adjustment groove.

[0026] By adopting the above technical solution, after the adjustment part is moved into place, the locking block can be inserted into the adjacent locking slot to prevent the adjustment part from moving freely relative to the moving part, thereby improving the overall stability of the connecting piece body.

[0027] Optionally, a frustum-shaped rotating shaft is fixed to the side of the fixing part facing the adjusting part, and a rotating groove is provided on the adjusting part to rotate with the rotating shaft. The diameter of the rotating shaft and the inner diameter of the rotating groove both gradually increase in the direction from the fixing part to the adjusting part.

[0028] By adopting the above technical solution, the fixed part and the adjusting part can rotate relative to each other around the rotating shaft, thereby changing the angle formed by the fixed part and the moving part to adapt to electrical accessories of different shapes, which is highly practical.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. When connecting an external conductive sheet, first insert the conductive sheet into the mounting hole, and then use soldering to weld the conductive sheet, mounting part and connecting sheet body into one piece. After the welding is in place, the solder will remain in the receiving cavity and the guide hole. The connection area between the conductive sheet and the connecting sheet body is large and the connection stability is high.

[0031] 2. The bent part will press against the conductive sheet when the conductive sheet is inserted into the mounting hole, which not only makes it difficult for the conductive sheet to move relative to the mounting ring, but also prevents the solder from flowing out from the gap between the conductive sheet and the mounting ring to a certain extent;

[0032] 3. The adjusting part can slide relative to the movable part, so that the overall length of the connecting piece body can be adjusted to accommodate electrical accessories of different lengths; the adjusting part can rotate relative to the fixed part, so that the angle formed between the fixed part and the movable part can be adjusted to accommodate electrical accessories of different shapes, making it highly practical.

[0043] The following is in conjunction with the appendix Figure 2-8 This application will be described in further detail.

[0044] This application discloses a connecting piece.

[0045] Example 1

[0046] Reference Figure 2 and Figure 3 The connecting piece includes a connecting piece body 1 made of conductive material. The connecting piece body 1 includes a fixed part 11, a movable part 12 located on one side of the fixed part 11, and an adjusting part 13 rotatably disposed on the side of the fixed part 11 facing the movable part 12. The adjusting part 13 is slidably disposed in the movable part 12. When the connecting piece is used in electrical accessories such as charging boxes, the operator can change the total length of the connecting piece body 1 by controlling the length of the adjusting part 13 extending into the movable part 12; or change the angle formed by the fixed part 11 and the movable part 12 by rotating the fixed part 11 relative to the adjusting part 13, thereby adapting to electrical accessories of different sizes.

[0047] Reference Figure 3 and Figure 4 A rotating shaft 111 is fixed to the side of the fixing part 11 facing the adjusting part 13. A rotating groove 131 is formed on the side of the adjusting part 13 facing the fixing part 11. The rotating shaft 111 is rotatably disposed in the rotating groove 131, so that the fixing part 11 and the adjusting part 13 can rotate relative to each other around the rotating shaft 111. In order to prevent the fixing part 11 and the adjusting part 13 from rotating arbitrarily, a rubber pad 132 is fixedly provided on the groove wall of the rotating groove 131 to increase the frictional resistance generated between the rotating shaft 111 and the groove wall of the rotating groove 131.

[0048] In this embodiment, both the rotating shaft 111 and the rotating groove 131 are truncated cone-shaped, and the diameter of the rotating shaft 111 and the inner diameter of the rotating groove 131 gradually increase along the direction from the fixing part 11 to the adjusting part 13, thereby making it difficult for the rotating shaft 111 to come out of the rotating groove 131. In other embodiments, the rotating shaft 111 and the rotating groove 131 may also be truncated cone-shaped, with the diameter of the end of the stepped cone near the fixing part 11 being smaller than the diameter of the end away from the fixing part 11.

[0049] It should be noted that, in order for the rotating shaft 111 to enter the rotating groove 131, in actual production, the adjusting part 13 can be divided into two independent plates, and an arc groove can be opened on each plate. Then, the two plates are spliced ​​on the outside of the rotating shaft 111 by welding or other means, so that the two plates combine to form the adjusting part 13 and the two arc grooves combine to form the rotating groove 131.

[0050] Reference Figure 4 The movable part 12 has an adjustment groove 121 on its side facing the fixed part 11. The extension direction of the adjustment groove 121 is parallel to the length direction of the movable part 12. The adjustment part 13 is slidably disposed in the adjustment groove 121. Multiple locking blocks 133 are fixed to the opposite end faces of the adjustment part 13. The locking blocks 133 are made of rubber material capable of elastic deformation. Multiple slots 122 are formed on the opposite side walls of the adjustment groove 121. The slots 122 on the same side wall of the adjustment groove 121 are equidistantly distributed along the extension direction of the adjustment groove 121. This embodiment illustrates its structure with three locking blocks 133 on each side of the adjustment part 13 and three slots 122 on each side wall of the adjustment groove 121. In other embodiments, the number of locking blocks 133 and slots 122 can also be different. After the adjustment part 13 is moved into place, each locking block 133 can be embedded into the adjacent locking slot 122 to prevent the moving part 12 and the adjustment part 13 from moving relative to each other, thereby improving the overall stability of the connecting piece body 1.

[0051] Reference Figure 2 and Figure 5The fixed part 11 has a clearance groove 2, and the bottom wall of the clearance groove 2 has a connecting hole 3. The movable part 12 has several through holes 123. Both the connecting hole 3 and the through holes 123 can be used to insert conductive connectors from electrical accessories to achieve circuit connection between the connector body 1 and the connector. In addition, the movable part 12 also has two integrally formed pins for connecting circuit boards or other connectors.

[0052] Reference Figure 5 and Figure 6 A mounting component 4 is detachably mounted on the fixing part 11. The mounting component 4 includes a hollow mounting ring 41 and an extension ring 42 integrally formed on the outer wall of the mounting ring 41. The mounting ring 41 passes through the connecting hole 3, and the extension ring 42 is located outside the connecting hole 3. In this embodiment, both the mounting ring 41 and the extension ring 42 are made of the same conductive material as the connecting piece body 1, such as copper alloy, and the length of the mounting ring 41 is greater than the thickness of the connecting piece body 1.

[0053] Reference Figure 5 and Figure 6 The mounting ring 41 has a through mounting hole 411 in the middle, which allows the conductive sheet to be inserted to connect the conductive sheet to the mounting component 4. To improve the stability of the conductive sheet when inserted into the mounting hole 411, anti-slip textures 412 are provided at both ends of the hole wall. The anti-slip textures 412 can increase the friction between the mounting ring 41 and the conductive sheet, making it less likely for the conductive sheet to fall out of the mounting ring 41.

[0054] Reference Figure 5 and Figure 6 The connecting piece body 1 has a positioning groove 5 on its side wall, which is provided with a clearance groove 2. The positioning groove 5 is annular and surrounds the outside of the clearance groove 2. The distance between the positioning groove 5 and the connecting hole 3 is less than the distance between the extension ring 42 and the mounting ring 41. Rubber rings 51 that can produce elastic deformation are fixed on the opposite sides of the positioning groove 5. A positioning ring 423 is integrally formed on the side of the extension ring 42 facing the connecting piece body 1. The width of the positioning ring 423 is slightly larger than the minimum distance between the two rubber rings 51 in the positioning groove 5, so that the positioning ring 423 can be inserted into the positioning groove 5 to realize the detachable connection between the mounting part 4 and the connecting piece body 1.

[0055] Reference Figure 5 and Figure 6When the positioning ring 423 is inserted into the positioning groove 5, the extension ring 42 covers the outside of the openings of the positioning groove 5 and the clearance groove 2, so that an annular receiving cavity 6 is formed between the mounting member 4 and the connecting piece body 1. The extension ring 42 has two feed holes 421 communicating with the receiving cavity 6, which are used to inject solder into the receiving cavity 6 from the outside. The mounting ring 41 has two guide holes 413 communicating with the receiving cavity 6 on its two opposite side walls. The guide holes 413 are used to guide the solder in the receiving cavity 6 to the gap between the conductive piece and the mounting ring 41, so that the conductive piece, the mounting member 4 and the connecting piece body 1 can be connected into one piece by welding.

[0056] Reference Figure 5 To further improve the connection stability between the conductive sheet and the mounting part 4, a bent part 414 is punched inward on the side wall of the mounting ring 41. The bent part 414 is located on the side of the guide hole 413 away from the feed hole 421, and is used to press the conductive sheet against the conductive sheet when the conductive sheet is inserted into the mounting hole 411.

[0057] The implementation principle of a connecting piece according to an embodiment of this application is as follows: When attaching a conductive piece to the connecting piece body 1, first insert the mounting ring 41 into the connecting hole 3 and the positioning ring 423 into the positioning groove 5, so that a receiving cavity 6 is formed between the mounting part 4 and the connecting piece body 1. Then, the conductive piece is inserted into the mounting hole 411 to achieve pre-installation of the conductive piece. Then, molten solder is injected into the receiving cavity 6 through the feed hole 421, so that the solder seeps into the gap between the mounting ring 41 and the conductive piece through the guide hole 413, thereby connecting the conductive piece, the mounting part 4 and the connecting piece body 1 into one by soldering. After the soldering is in place, the solder will remain in the receiving cavity 6 and the guide hole 413 to increase the connection area between the conductive piece and the connecting piece body 1 and improve the connection strength between the two.

[0058] Example 2

[0059] Reference Figure 7 and Figure 8 The difference between this embodiment and Embodiment 1 is that: the extension ring 42 has several positioning screw holes 422, the distribution direction of the positioning screw holes 422 is the same as the extension direction of the positioning groove 5, and when the mounting part 4 is assembled onto the connecting piece body 1, each positioning screw hole 422 is aligned with the positioning groove 5. Each positioning screw hole 422 is threaded with a positioning bolt 7, the diameter of the shank of the positioning bolt 7 is slightly smaller than the width of the positioning groove 5, and the design of the rubber ring 51 in the positioning groove 5 is correspondingly omitted.

[0060] Reference Figure 7 and Figure 8After the extension ring 42 abuts against the connecting piece body 1, the operator can thread the positioning bolt 7 into the positioning bolt hole 422 and make the shank of the positioning bolt 7 press against the bottom wall of the positioning groove 5, thereby using the head of the positioning bolt 7 to press the extension ring 42 onto the connecting piece body 1, resulting in a high connection strength between the mounting part 4 and the connecting piece body 1.

[0061] In other embodiments, only a smooth-walled through hole can be opened on the extension ring 42, and the positioning groove 5 can be changed to a design of multiple spaced screw holes so that the positioning bolt 7 can be threaded onto the connecting piece body 1 after passing through the through hole; or the design of the rubber ring 51 in embodiment 1 can be retained to further improve the stability of the positioning bolt 7 when it is pressed against the bottom wall of the positioning groove 5.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
