Description

[Technical field]

[0001] The invention relates to the technical field of electronic products, and in particular to a structure for preventing an interface from being misaligned. [Background technology]

[0002] The assembly process of a notebook computer in the prior art is as follows: Figure 1 As shown, the hardware interface 201 (such as the Type-C interface) is pre-soldered directly on the edge of the PCB board 2. During assembly, the PCB board 2 is directly placed in the laptop computer shell (such as the C shell and D shell of the laptop) and the PCB board 2 is fixed to the laptop computer shell.

[0003] However, after the assembly is completed according to the above process, the hardware interface 201 is prone to displacement. The reasons are as follows: when the PCB board 2 is fixed, only the PCB board 2 is positioned, and the hardware interface 201 is not positioned separately. There is an accumulation of tolerances in the design of the PCB board 2 and the shell, which causes the hardware interface 201 to be displaced. [Summary of the invention]

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that the hardware interface is easily misaligned after the PCB board and the shell of the notebook are assembled, the present invention provides a structure to prevent the interface from being misaligned to solve the above problem.

[0006] A fixing member, wherein a second interface hole is formed on the fixing member; the fixing member is fixed to the outer side of the housing, and the second interface hole corresponds to the position of the first interface hole;

[0007] A positioning protrusion is also provided on one side of the fixing member facing the housing;

[0008] The housing is also provided with a through hole at a position corresponding to the positioning protrusion, and the positioning protrusion extends into the housing from the through hole;

[0009] The PCB board is also provided with a notch at a position corresponding to the positioning protrusion.

[0010] Preferably, a portion of the positioning protrusion is located in the notch.

[0011] Preferably, the number of the positioning protrusions is two, and the two positioning protrusions are respectively located on both sides of the first interface hole.

[0012] Preferably, the fixing member is a metal member.

[0013] Preferably, the positioning protrusion is a rivet riveted on the fixing member.

[0014] Preferably, the fixing member is fixed to the housing by screws.

[0015] Preferably, the assembly gap between the hardware interface and the first interface hole is 0.2 mm.

[0016] Preferably, a surface of the fixing member facing away from the housing is chamfered along an edge of the second interface hole.

[0017] Preferably, the shell is a C shell or a D shell of a notebook.

[0018] Preferably, the hardware interface is a Type-C interface.

[0019] The beneficial effect of the present invention is that the interface that prevents interface displacement can ensure that the hardware interface is not displaced after assembly, and the fixing part is arranged on the outside of the shell and does not occupy the space inside the shell. It is suitable for models with many interfaces welded on the PCB, large assembly tolerance and small space inside the shell.

[0028] See also Figure 2 and Figure 3 The present invention provides a structure for preventing the interface from being misaligned, including a housing 1, a PCB board 2, and a hardware interface 201 (such as a Type-C interface). Figure 4 The hardware interface 201 is fixed to the PCB board 2, and the housing 1 is provided with a first interface hole 101. The PCB board 2 is fixedly arranged in the housing 1, and the hardware interface 201 extends into the first interface hole 101. This structure for preventing the interface from being offset also includes:

[0029] See also Figure 4 and Figure 6 The fixing member 3 has a second interface hole 301 formed thereon. The fixing member 3 is fixed to the outer side of the housing 1 , and the second interface hole 301 corresponds to the position of the first interface hole 101 .

[0030] A positioning protrusion 302 is also provided on a side of the fixing member 3 facing the housing 1 .

[0031] The housing 1 is further provided with a through hole 102 at a position corresponding to the positioning protrusion 302 , and the positioning protrusion 302 extends into the housing 1 through the through hole 102 .

[0032] The PCB board 2 is further provided with a notch 202 at a position corresponding to the positioning protrusion 302 .

[0033] See also Figures 3 to 6 The working principle of this structure to prevent interface deviation is as follows:

[0034] During assembly, the hardware interface 201 is aligned with the first interface hole 101, and the PCB board 2 is placed in the housing 1. If the position of the hardware interface 201 is offset, the notch 202 of the PCB board 2 will not be aligned with the positioning protrusion 302, and the positioning protrusion 302 will interfere with the upper surface or the lower surface of the PCB board 2, resulting in the PCB board 2 being unable to be placed in the housing 1. The staff will adjust the position of the PCB board 2 and the hardware interface 201 and assemble them again, thereby preventing the hardware interface 201 from being offset after assembly.

[0035] The beneficial effect of the present invention is that the interface that prevents the interface from being misaligned can ensure that the hardware interface 201 is not misaligned after assembly, and the fixing part 3 is arranged on the outside of the shell 1 and does not occupy the space inside the shell 1. It is suitable for models with many interfaces soldered on the PCB, large assembly tolerance, and small space inside the shell 1.

[0036] See also Figure 2 and Figure 5 , wherein a portion of the positioning protrusion 302 is located in the notch 202. After assembly, a portion of the positioning protrusion 302 of the structure for preventing the interface from being offset is located in the notch 202, which is conducive to ensuring that the hardware interface 201 is not offset.

[0037] See also Figure 5 and Figure 6 , wherein the number of the positioning protrusions 302 is two, and the two positioning protrusions 302 are respectively located on both sides of the first interface hole 101. Correspondingly, the number of the through holes 102 on the housing 1 and the number of the notches 202 on the PCB board 2 are also two.

[0038] The two positioning protrusions 302 are respectively located on both sides of the first interface hole 101. During assembly, if the position of the hardware interface 201 is offset, the positioning protrusions 302 can better interfere with the upper surface or lower surface of the PCB board 2 to ensure that the PCB board 2 cannot be placed in the shell 1.

[0039] The fixing member 3 is a metal member, which has a stable structure, is not easy to wear, and has a good positioning effect.

[0040] The positioning protrusion 302 is a rivet fixed on the fixing member 3. The rivet is used as the positioning protrusion 302 for easy processing.

[0041] The fixing member 3 is fixed to the housing 1 by screws.

[0042] The assembly clearance between the hardware interface 201 and the first interface hole 101 is 0.2 mm, which enables the first interface hole 101 to position the hardware interface 201 and also enables the hardware interface 201 to be smoothly inserted into the first interface hole 101 .

[0043] The side of the fixing member 3 facing away from the housing 1 is chamfered along the edge of the second interface hole 301. The chamfer can reduce the sharpness of the edge.

[0044] The housing 1 is a C-shell or a D-shell of a notebook.

[0045] Among them, the hardware interface 201 is a Type-C interface.

[0046] It should be pointed out that the present invention is not limited to the above-mentioned implementation modes, and any simple modifications, equivalent changes and modifications made to the above-mentioned embodiments by any technician familiar with the profession based on the technical solution of the present invention fall within the protection scope of the present invention.
