Description

Technical Field

[0001] This utility model relates to the field of water purifier wiring harness fixing technology, and in particular to a snap-fit ​​DC plug structure. Background Technology

[0002] When a DC plug is used in a water purifier, the first end of the DC plug is fixed to the mounting plate, and the second end of the DC plug is fitted with a connecting terminal (housing). The DC plug includes a first end, a wire harness, and a connecting terminal (housing). The wire harness connects the first end and the connecting terminal (housing). The first end is provided with a limiting ring and threads. When fixing the first end of the DC plug to the mounting plate, a nut is usually passed through the connecting terminal (housing) and then moved along the wire harness of the DC plug, close to the fixing plate, and finally engages with the threads on the DC plug. By tightening the nut, the nut and the ring can clamp the mounting plate, thereby fixing the first end of the DC plug to the mounting plate.

[0003] The above operation presents a problem: some connector terminals are relatively large, and in such cases, the nut may not be able to pass through the end of the connector (housing). In this situation, it's necessary to disassemble the connector (housing) from the wiring harness, then pass the nut through the wiring harness and thread it to secure the DC connector's head to the mounting plate. This increases the time required for DC connector assembly and disassembly, reducing efficiency. Furthermore, it results in only semi-finished products being shipped; terminals without housings are difficult to protect during manufacturing and transportation, posing a risk of defects. This directly reduces customer production efficiency and increases secondary assembly costs. Additionally, installing housings at the customer's end carries risks of incorrect wiring sequence, incomplete housing insertion, pin detachment, and poor contact. Utility Model Content

[0004] The main purpose of this invention is to propose a snap-fit ​​DC plug structure, which aims to improve the efficiency of plug assembly and disassembly.

[0005] To achieve the above objectives, the present invention proposes a snap-fit ​​DC plug structure for connection to an external device. The external device includes a housing with mounting holes, comprising:

[0006] A plug body, comprising an abutting section and a main body section, wherein the main body section is inserted into the mounting hole, and the abutting section abuts against one side of the housing; and

[0007] The elastic buckle has a disassembly part for cooperating with a disassembly tool. When the plug body is installed, the elastic buckle is elastically engaged with the body section and abuts against the side of the housing opposite to the abutment section. When the plug body is disassembled, the elastic buckle is disengaged from the body section by the cooperation of the disassembly tool and the disassembly part.

[0008] In one embodiment, the disassembly part is a disassembly hole, and the disassembly tool is inserted into the disassembly hole to cause the elastic buckle to elastically deform and disengage from the main body segment.

[0009] In one embodiment, the disassembly part is a disassembly plate connected to the elastic buckle, and the disassembly tool pries the disassembly plate to cause the elastic buckle to elastically deform and detach from the main body section.

[0010] In one embodiment, the disassembly plate is provided with a limiting part, and the disassembly tool prys the disassembly plate through the limiting part.

[0011] In one embodiment, the limiting portion is a first limiting plane.

[0012] In one embodiment, the elastic buckle includes two elastic arms disposed opposite to each other. Each elastic arm includes a locking section, a limiting section, and a guiding section disposed sequentially. The guiding section guides the elastic buckle to engage with the main body section. The locking section engages with the outer peripheral wall of the main body section. The limiting section restricts the locking section from disengaging from the main body section.

[0013] In one embodiment, the width of the guide segment is gradually increased along the direction approaching the limiting segment.

[0014] In one embodiment, the main body section is provided with an annular limiting hole, the elastic buckle is inserted into the limiting hole, and the elastic buckle abuts against the side of the housing opposite to the abutting section.

[0015] In one embodiment, the main body segment is provided with a second limiting plane, and the wall of the mounting hole is provided with a third limiting plane, wherein the second limiting plane and the third limiting plane are in contact and abut against each other.

[0016] In one embodiment, the outer periphery of the main body segment is provided with a threaded structure.

[0017] The plug in this utility model includes a plug body and an elastic buckle. The plug body includes an abutment section and a main body section. The main body section is inserted into the mounting hole, and the abutment section abuts against one side of the housing. The elastic buckle is provided with a disassembly part for cooperating with a disassembly tool. When the plug body is installed, the elastic buckle is elastically engaged with the main body section and abuts against the side of the housing away from the abutment section. When the plug body is disassembled, the elastic buckle is disengaged from the main body section by cooperating with the disassembly tool and the disassembly part. Therefore, compared with the prior art solution of installing the plug with a nut, the present application's technical solution greatly improves the efficiency of connector assembly and disassembly by using an elastic buckle. At the same time, by providing a disassembly part on the elastic buckle, it is easy to disassemble the plug body, thereby improving the efficiency of DC plug assembly and disassembly.

[0030] Reference Figures 1 to 5 This utility model proposes a snap-fit ​​DC plug structure for connecting to an external device. The external device includes a housing 10, and the housing 10 has mounting holes 11, including:

[0031] The plug body 20 includes an abutment section 21 and a main body section 22, the main body section 22 being inserted into the mounting hole 11, and the abutment section 21 abutting against one side of the housing 10; and

[0032] The elastic buckle 30 is provided with a disassembly part for cooperating with a disassembly tool. When the plug body 20 is installed, the elastic buckle 30 is elastically engaged with the body section 22 and abuts against the side of the housing 10 away from the abutment section 21. When the plug body 20 is disassembled, the elastic buckle 30 is disengaged from the body section 22 by the cooperation of the disassembly tool and the disassembly part.

[0033] The plug in this utility model includes a plug body 20 and an elastic buckle 30. The plug body 20 includes an abutment section 21 and a main body section 22. The main body section 22 is inserted into the mounting hole 11, and the abutment section 21 abuts against one side of the housing 10. The elastic buckle 30 is provided with a disassembly part for cooperating with a disassembly tool. When the plug body 20 is installed, the elastic buckle 30 is elastically engaged with the main body section 22 and abuts against the side of the housing 10 away from the abutment section 21. When the plug body 20 is disassembled, the elastic buckle 30 is disengaged from the main body section 22 through the cooperation of the disassembly tool and the disassembly part. Therefore, compared with the prior art solution of installing the plug with a nut, the present application's technical solution greatly improves the disassembly and assembly efficiency of the connector by using the elastic buckle 30. At the same time, by providing a disassembly part on the elastic buckle 30, the disassembly of the plug body 20 is facilitated, thereby improving the disassembly and assembly efficiency of the DC plug.

[0034] Furthermore, in the existing technical solution, the end of the main body segment 22 away from the abutment segment 21 is connected to a housing via a wire. This housing enables quick docking and electrical connection with other electronic devices. However, in the existing solution, when the main body segment 22 is connected using a nut, the diameter of the nut hole is smaller than the width of the housing. This necessitates disassembling and assembling the nut before installing the housing at the end of the wire away from the main body segment 22, and then transporting the nut, main body segment 22, wire, and housing together. This results in a complex manufacturing process for the DC plug, leading to high production costs. In contrast, the technical solution of this application only requires disassembling and assembling the main body segment 22, wire, and housing, and then transporting them separately from the elastic clip 30. This significantly simplifies the manufacturing process of the DC plug and reduces its production costs.

[0035] Reference Figure 1 and Figure 4 In Embodiment 1, the disassembly part is a disassembly hole 31. The disassembly tool is inserted into the disassembly hole 31 to cause the elastic buckle 30 to elastically deform and detach from the main body section 22. The disassembly tool is a caliper 40. By inserting the caliper pin provided on the caliper 40 into the disassembly hole 31 and then pulling it outward in a specific direction, the elastic buckle 30 can be detached from the main body section 22, thereby greatly improving the disassembly and assembly efficiency of the elastic buckle 30.

[0036] Reference Figure 2 and Figure 4In the second embodiment, the disassembly part is a disassembly plate 32 connected to the elastic buckle 30. The disassembly tool pries the disassembly plate 32 to cause the elastic buckle 30 to elastically deform and detach from the main body section 22. By using a disassembly tool or by the user directly prying or pulling the elastic buckle 30, the elastic buckle 30 can be detached from the main body section 22, thereby greatly improving the disassembly and assembly efficiency of the elastic buckle 30.

[0037] Furthermore, the disassembly plate 32 is provided with a limiting part, and the disassembly tool prys the disassembly plate 32 through the limiting part. The disassembly tool is a caliper 40, which is provided with a locking pin. The user holds the caliper 40 by hand, and then the locking pin locks onto the disassembly plate 32. Then, by prying or pulling the caliper 40, the elastic buckle 30 is disengaged from the main body section 22.

[0038] Specifically, the limiting part is a first limiting plane 321. The locking pin on the caliper 40 is flat or has two limiting planes that cooperate with the first limiting plane 321. This prevents the caliper 40 from easily disengaging from the elastic latch 30 when it is pulled or pried, thus facilitating the use of the caliper 40 and the removal of the DC plug. Of course, in other embodiments, the limiting part can also be a limiting groove, a limiting hole 221, etc.

[0039] Reference Figures 3 to 5 Specifically, the elastic buckle 30 includes two elastic arms 33 arranged opposite each other. Each elastic arm 33 includes a locking section 331, a limiting section 332, and a guiding section 333 arranged sequentially. The guiding section 333 guides the elastic buckle 30 to engage with the main body section 22. The locking section 331 is engaged with the outer peripheral wall of the main body section 22. The limiting section 332 prevents the locking section 331 from disengaging from the main body section 22. The elastic arm 33 has a simple structure with few components, thereby reducing the manufacturing cost of the elastic buckle 30.

[0040] Furthermore, the width of the guide segment 333 gradually increases along the direction close to the limiting segment 332. This makes it easier for the guide segment 333 to snap into the main body segment 22. On the other hand, during the elastic deformation of the elastic buckle 30, the guide segment 333 has the greatest deformation. By setting the width of the guide segment 333 in a gradually changing manner, it is easier for the guide segment 333 to deform, thus making it easier for the user to insert the elastic buckle 30 into the main body segment 22.

[0041] In one embodiment, the main body segment 22 is provided with an annular limiting hole 221, and the elastic buckle 30 is engaged in the limiting hole 221, with the elastic buckle 30 abutting against the side of the housing 10 opposite to the abutting segment. By providing the annular limiting hole 221, the annular limiting hole 221 limits the elastic buckle 30 in the circumferential direction, preventing the elastic buckle 30 from shifting in the axial direction, thereby improving the locking effect of the elastic buckle 30 and thus improving the reliability of the plug body 20.

[0042] Specifically, the main body segment 22 is provided with a second limiting plane 222, and the wall of the mounting hole 11 is provided with a third limiting plane 111. The second limiting plane 222 and the third limiting plane 111 fit and abut against each other, thereby restricting the circumferential rotation of the main body segment 22, thereby improving the stability and reliability of the plug body 20.

[0043] Specifically, the outer periphery of the main body segment 22 is provided with a threaded structure 223. By providing an external thread on the outer periphery of the main body segment 22, it is convenient to further limit the main body segment 22 with a nut, or to fix it with a nut alone, thereby improving the application scenarios of the DC plug and enhancing its practicality.

[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
