[0027] As follows:

[0028] Please refer to the accompanying Figures 1-7 ,

[0029] Main structure includes the charger main body 1 by the frame 10 and replaceable wire assembly 2, replaceable wire assembly 2 includes the mounting plate 23 opened on the frame 10, the mounting plate 23 is equipped with through hole 22 and fixed hole 32, the mounting plate 23 one side is equipped with circuit board 20, and the copper needle 200 is equipped on the circuit board 20, and the copper needle 200 is communicated with the outside through the through hole 22, the other side of the mounting plate 23 is equipped with the joint 3 connected with the wire 31, and the joint 3 is equipped with the contact 30 for contacting with the copper needle 200, and the fixed hole 32 is also opened on the joint 3, and the joint 3, the mounting plate 23 are connected through the cooperation of fixed hole 32, realize replaceable wire connection.

[0030] Working principle is as follows:

[0031] From structure, the mounting plate 23 is opened on the frame 10, and the circuit board 20 is assembled on the side of the mounting plate 23 close to internal element, and the copper needle 200 is equipped on the circuit board 20 as a through piece, the copper needle 200 is communicated with the outside after passing through the mounting plate 23, and the other side of the mounting plate 23 is the connecting point of the whole circuit, and the circuit is composed of joint 3 and wire 31, and the contact 30 is also equipped on the joint 3, and the contact 30 is mainly used for the communication of the copper needle 200 on the side of the mounting plate 23 after the assembly of the whole charger main body 1, and the fixed hole 32 is also equipped on the mounting plate 23 and joint 3, and can be fixed by screwing and the like. From the use mode, when the wire is removed and replaced, it is removed through the fixed hole 32, and it can be fixed after assembly.

[0032] The current self-wired charger structure is mainly fixed and cannot be detached, such as welding, if the wire needs to be replaced, the entire shell needs to be opened, or the pcb, structural parts and other components need to be detached, the wire connection position needs to be cut or melted, and then the shell is assembled after re-welding, which not only has the risk of scratching and damaging the shell structure, but also needs to use multiple tools, and some shells and charger main bodies are integrated at the wiring position, which is not convenient to detach and needs to be cut or melted. The detachable and easy-to-replace wire structure realized by the scheme solves the above problems. In addition, the whole structure of the replaceable wire assembly 2 is simple, and no more structural changes are made to the whole charger product to ensure the overall structural strength.

[0033] With reference to the accompanying drawings Figure 2 In a preferred embodiment of the utility model, the replaceable wire assembly 2 further comprises a pressing plate 21 for pressing the circuit board 20 and the mounting plate 23.

[0034] The pressing plate 21 serves as a limiting piece and is mainly used for pressing and limiting the circuit board 20 after assembly to prevent the circuit board 20 from retreating inward. After installation, one side of the pressing plate 21 will “resist” the circuit board 20, so that the head of the copper needle 200 on the circuit board 20 is kept at the preset position in the through hole 22, effectively preventing poor contact and stabilizing the circuit board 20.

[0035] With reference to the accompanying drawings Figure 7 In a preferred embodiment of the utility model, the pressing plate 21 is provided with a convex point 210 for further pressing the circuit board 20.

[0036] The pressing plate 21 can be an integral structure, and the convex point 210 provided on one side of the pressing plate 21 close to the circuit board 20 can further stabilize the circuit board 20 after assembly. If there is no convex point 210, one side of the pressing plate 21 serves as a flat surface and is attached to the circuit board 20, and the circuit board 20 is insufficiently stressed. The convex point 210 can be a slightly elastic convex structure, such as a common spring piece, which deforms after contacting the main board to make the circuit board 20 have certain buffering properties.

[0037] With reference to the accompanying drawings Figures 2-4 In a preferred embodiment of the utility model, the mounting plate 23 is further provided with a positioning column 24 for positioning and mounting the circuit board 20.

[0038] The positioning column 24, as a positioning structure during assembly, can prevent the circuit board 20 from being skewed and can also stabilize the circuit board 20 after assembly. The positioning column 24 is provided with at least two columns, which can be arranged horizontally or vertically. The positioning column 24 can also be an integral structure with the mounting plate 23, which is directly formed by extrusion or welding during the manufacturing of the mounting plate 23 to maintain the structural strength.

[0039] With reference to the accompanying drawings Figure 3 , 5 -6, in a preferred embodiment of the utility model, the mounting plate 23 is a two-side symmetrical structure.

[0040] In the scheme, the charger main body 1 can include at least two wires, and each wire is detachable and replaceable through the replaceable wire assembly 2. The two wires are assembled on the two sides of the mounting plate 23, and can be wires of the same or different models.

[0041] With reference to the accompanying drawings Figures 2-6 , in a preferred embodiment of the utility model, the replaceable wire assembly 2 is arranged near the internal corner of the frame.

[0042] Considering that the side frame surface of the charger main body 1 needs to be provided with a key, a screen or an interface, the replaceable wire assembly 2 is arranged at the corner, which does not affect the arrangement of other components on the side frame surface and can match the arrangement position of the circuit board 20. Because the space inside the charger main body 1 is occupied by various elements such as a battery, in order to fully dissipate heat during work, these elements are mostly arranged in a flat manner, and therefore the circuit board 20 is arranged at the corner.

[0043] With reference to the accompanying drawings Figure 3 , in a preferred embodiment of the utility model, the frame 10 is an integral frame structure, and the mounting plate 23 is an integral thermoplastic forming structure of the frame 10.

[0044] In order to maintain the structural strength of the mounting plate 23 and the frame 10, the frame 10 can be formed by one-time forming, and the mounting plate 23 is directly formed by extrusion from the structure of the frame 10. When the frame 10 is a metal piece, the mounting plate 23 can be fixed to the frame 10 by welding. Regardless of the connection method of the mounting plate 23 and the frame 10, the connection strength and the non-detachable characteristics need to be ensured, which not only facilitates the manufacturing and eliminates the setting of other fixing structures such as holes and fixing pieces, but also enhances the connection strength.

[0045] With reference to the accompanying drawings Figure 7 , in a preferred embodiment of the utility model, the pressing plate 21 is in a "Fang" shape structure, and the top is provided with a fixed position for fixing the inside of the frame 10, and the circuit board 20 is fixed after assembly.

[0046] The pressing plate 21 frames the circuit board 20 after being fixedly assembled, and the circuit board 20 is located inside the "Fang" shaped structure, which protects one side of the circuit board 20 and also limits the circuit board. The pressing plate 21 can also be other structures, such as "Gong" shaped structure, etc. In the present scheme, in order to save internal space, the "Fang" shaped structure with one side opening is adopted. The pressing plate 21 can also be an integrated structure, as a small part, which can be obtained by one-time stamping, bending or injection molding process, etc.

[0047] With reference to the accompanying drawings Figure 4 In a preferred embodiment of the present application, the frame 10 has a wire slot 11 for accommodating the wire 31.

[0048] The wire slot 11 is used to accommodate the wire 31 when not in use. The connector 3 can be located at one end of the wire slot 11, and the other end of the wire slot 11 is used to accommodate the charging head. The middle slot is used to accommodate the wire 31.

[0049] The above is only a preferred embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structural transformation or direct / indirect application in other related technical fields within the scope of the present application is included in the patent protection range of the present application.
