Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1-6As shown, this utility model provides a plug mounting structure, including a power-connecting plug 1 for a plug 10 and a fixing member 2. One end of the power-connecting plug 1 is a power-connecting end 11, and the other end is a fixing end 3. The fixing end 3 is provided with a recess 21 for engaging with the fixing member 2. The fixing member 2 is used to connect the power-connecting plug 1 to the plug 10. Insert the fixed end 3 of the power connector 1 into the fixing member 2 of the plug 10 until the recess 21 corresponds to the fixing member 2, and use the device to squeeze the fixing member 2 into the recess 21.

[0024] Furthermore, such as Figures 1-5 As shown, the fixed end 3 forms a protrusion 22 on the side of the recess 21. After the fixing member 2 is squeezed into the recess 21, the protrusion 22 limits and squeezes the side of the fixing member 2.

[0025] Specifically, such as Figures 1-6 As shown, the fixing member 2 and the power connector 1 are separate structures. The fixing member 2 and the power connector 1 are fixedly installed through an extrusion process to form a suitable power connector structure inside the plug 10. The fixing member 2 can be a ring structure. The fixing member 2 is extruded by the equipment, so that the fixing member 2 is pressed into the recess 21. After extrusion, the two sides of the fixing member 2 are clamped and pressed by the protrusions 22 on both sides of the recess 21. It is worth noting that the line connecting the two protrusions 22 is parallel to the extension direction of the power connector 1, or the connection between the protrusions 22 is perpendicular to the extension direction of the power connector 1.

[0026] Furthermore, such as Figures 1-6 As shown, the recessed portion 21 includes a first groove 211. There are at least two sets of the first grooves 211, each of which is evenly distributed on the outer surface of the fixed end 3. The recessed portion 21 also includes a second groove 212, which is disposed through the fixed end 3.

[0027] Specifically, such as Figures 1-6 As shown, the device presses the fixing member 2 into the first groove 211. It is worth noting that the first groove 211 can be a groove-shaped structure. The first groove 211 is open to at least one side and opens away from the power connector 1. At the same time, the first groove 211 can also have through openings to both sides of the power connector 1. The direction of the through openings is perpendicular to the extension direction of the power connector 1. In addition, protrusions 22 can be provided on both sides of the first groove 211. The line connecting the two protrusions 22 is parallel to the extension direction of the power connector 1. In some embodiments, such as Figures 1-6As shown, the recessed portion 21 may also include a second groove 212. The second groove 212 is independent of the first groove 211 and may also be located within the first groove 211. It is worth noting that the second groove 212 may be a through hole-type structure. The through direction of the second groove 212 may be consistent with the opening direction of the first groove 211, that is, opening away from the power connector pin 1. Alternatively, the through direction of the second groove 212 may be perpendicular to the opening direction of the first groove 211. By pressing the fixing member 2 with the device, the fixing member 2 is simultaneously pressed and fixed into the first groove 211 and the second groove 212, achieving a more secure pressing effect compared to the embodiment with only the first groove 211.

[0028] Furthermore, such as Figures 1-6 As shown, the inner side of the fastener 2 has a pressing position 20 for contacting the fixed end 3. The fastener 2 includes a connecting section 23 and a deformable section 24. The connecting section 23 is used to fix the deformable section 24, and the deformable section 24 is used to engage with the recess 21.

[0029] like Figures 1-5 As shown, a deformation groove 231 is provided at the connection between the deformable section 24 and the connecting section 23. The deformable section 24 is provided with a snap-in end 201 located in the extrusion position 20, and a pressing end 202 corresponding to the snap-in end 201 is formed on the outer side of the deformable section 24. The snap-in end 201 is snapped into the recess 21 by the device pressing the pressing end 202.

[0030] Based on the above, such as Figures 1-6As shown, the snap-in end 201 on the deformable section 24 corresponds to the first groove 211. The device compresses and deforms the deformable section 24 into the first groove 211 by pressing the pressing end 202, and pushes the snap-in end 201 into the first groove 211 to achieve a compression fit. During this process, the deformation groove 231 deforms simultaneously. The deformation groove 231 is formed at the connection between the snap-in end 201 and the connecting section 23, and can also be formed at the connection between the pressing end 202 and the connecting section 23. It is worth noting that the deformation groove 231 is a groove-shaped structure formed by recessing into the deformable section 24. The deformation groove 231 between the pressing end 202 and the connecting section 23 is recessed towards the snap-in end 201, and the deformation groove 231 between the snap-in end 201 and the connecting section 23 is recessed towards the pressing end 202. The snap-in end 201 drives the two deformation grooves 231 on the same side to deform into the first groove 211, so that the two deformation grooves 231 on that side deform into the first groove 211. 1. The deformation groove 231 eliminates stress when the deformable section 24 deforms, preventing the deformable section 24 from breaking with the connecting section 23 when it deforms. When the deformation groove 231 is formed at the connection between the pressing end 202 and the connecting section 23, the pressing end 202 of the deformable section 24 integrates into the two deformation grooves 231 on the same side when it deforms, and the two deformation grooves 231 on this side are connected to form a gap. In addition, regardless of whether the deformation groove 231 is formed on both sides of the pressing end 202, the force of squeezing the deformable section 24 can be adjusted according to the needs of the plug 10 product. In some products that require a large squeezing force between the fixing part 2 and the power connection pin 1, a strong squeezing force is applied to the pressing end 202 of the deformable section 24 through external equipment, so that the deformable section 24 is strongly compressed into the recessed part 2, and a gap is formed at the original position of the pressing end 202 of the deformable section 24, which is recessed towards the recessed part 2.

[0031] In some embodiments, such as Figures 1-6 As shown, the recessed portion 21 includes a first groove 211 and a second groove 212. The structure of the deformable segment 24 for the first groove 211 is as described above and will not be repeated here. In this technology, the snap-in end 201 for the first groove 211 and the second groove 212 can be a conical structure to achieve better compression into the first groove 211 and the second groove 212. It is worth noting that the deformable segment 24 for the second groove 212 can have the same structure as the deformable segment 24 for the first groove 211, or the deformable segment 24 for the second groove 212 can be different from the deformable segment 24 for the first groove 211. At the same time, the pressing end 202 of the deformable segment 24 of the first groove 211 and the pressing end 202 of the deformable segment 24 of the second groove 212 protrude from the connecting segment 23. The deformation grooves 231 located on both sides of the pressing end 202 can be recessed in a direction that is closer to each other.

[0032] Furthermore, the fixed end 3 has a power receiving end 12 at the end away from the power plug end 11.

[0033] Specifically, such as Figures 1-6 As shown, the power receiving terminal 12 and the power plug terminal 11 are integrally formed, and the power receiving terminal 12 extends away from the power plug terminal 11 and is used to solder and conduct electricity with the wires inside the plug 10.

[0034] The following is a detailed explanation of the working principle of this utility model; The recessed portion 21 of the fixed end 3 on the power connector 1 is aligned with the fixing member 2. The fixing member 2 is pressed into the recessed portion 21 by the equipment, so that the fixing member 2 and the power connector 1 are snapped together. Then the fixing member 2 is welded to the plug 10, so that the power connector 1 is installed in the plug 10. Compared with the cold heading process, the production cost is reduced.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
