Description

Technical Field

[0002] Electrical appliances are widely used and are almost indispensable in modern life. While electronic products bring great convenience to people's lives, they also cause a lot of trouble when they are damaged and need repair.

[0003] Sometimes, when electrical products (such as air conditioners, remote controls, fans, etc.) are damaged, it is necessary to replace components on the circuit board or replace certain metal and plastic components fixed to the insert layer. After the after-sales staff and the user locate the damaged component, the component itself is difficult to remove due to the fixing method and lack of suitable installation tools, which increases the difficulty of component replacement and makes it difficult to implement component replacement.

[0004] Traditional components require specialized tools to disassemble and install. For example, components on a circuit board require welding to remove and replace. Some components cannot be replaced at all if damaged, such as in some appliances where some components are seamlessly integrated with the main body. Both of these situations can cause the entire appliance to malfunction or even become scrapped. Summary of the Invention

[0037] The present invention provides a pin structure 100 for cooperating with a preset component 200, please refer to Figures 1 to 5, the preset component 200 has a connecting hole 210; along the axial direction of the connecting hole 210, the preset component 200 has a first end and a second end arranged oppositely; the connecting hole 210 passes through the first end face and the second end face of the preset component 200; the pin structure 100 includes a body component 1, a stopper 40 and a blocking member 20, and the body component 1 is used to be inserted into the connecting hole 210; along the insertion direction of the body component 1, the body component 1 has a first end and a second end arranged oppositely; the insertion direction of the body component 1 is parallel to or the same as the axial direction of the connecting hole 210; the first end of the body component 1 is located outside the connecting hole 210, and the first end of the body component 1 is used to be fixedly connected to the device body 90; the outer surface of the body component 1 is exposed in the connecting hole A clamping portion 30 is provided on the portion outside 210; the stop portion 40 is used to clamp and cooperate with the clamping portion 30 to prevent the stop portion 40 from moving in the direction from the second end to the first end of the main body component 1, even if the stop portion 40 cannot move in the direction from the second end to the first end of the main body component 1; the stop portion 40 is used to abut against the first end face of the preset component 200; the blocking member 20 is movably provided at the second end of the main body component 1 to have a retracted state and a blocked state; when the blocking member 20 is in the retracted state, the blocking member 20 is used to pass through the connecting hole 210; when the blocking member 20 is in the blocked state, the blocking member 20 is bent outward relative to the main body component 1 to abut against the second end face of the preset component 200.

[0038] During the specific implementation process, the orientation from the first end to the second end of the preset component 200 is the same as the orientation from the first end to the second end of the main body component 1; along the axial direction of the connecting hole 210, the connecting hole 210 has a first end and a second end that are relatively arranged; the orientation from the first end to the second end of the preset component 200 is the same as the orientation from the first end to the second end of the connecting hole 210.

[0039] The blocking member 20 of the pin structure 100 is in a retracted state; the pin structure 100 is then passed into the connecting hole 210 from the first end of the connecting hole 210 in a direction from the first end to the second end of the main body component 1, so that the blocking member 20 passes through the connecting hole 210, and the main body component 1 is passed into the connecting hole 210; the blocking member 20 is then bent outward relative to the main body component 1, so that the blocking member 20 is changed from the retracted state to the blocking state; and the blocking member 20 in the blocking state is aligned with the first end of the preset component 200. The two end faces are fixedly abutted; then the stop portion 40 is snap-fitted with the clamping portion 30, and the stop portion 40 is fixedly abutted with the first end face of the preset component 200; due to the snap-fitting action of the stop portion 40 and the clamping portion 30, the stop portion 40 cannot move in the direction from the second end to the first end of the main body component 1; and then under the joint abutment action of the stop portion 40 and the clamping member 20, the main body component 1 and the preset component 200 are locked and fixed, thereby realizing the fixed connection between the device body 90 and the preset component 200.

[0040] When the pin structure 100 is to be detached from the preset component 200, the first end of the body assembly 1 is cut off from the device body 90 by using a cutting tool; then the clamping piece 20 is retracted so that the clamping piece 20 is switched from the clamping state to the retracted state; and then the pin structure 100 is detached from the connecting hole 210 in the direction from the second end to the first end of the body assembly 1.

[0041] The pin structure 100 of the present application is a detachable pin structure, which solves the problem of inconvenient disassembly of the components with pins in the prior art.

[0042] The loading mode of the common pin component is to extend the pin into the pad hole and solder it with a tin wire at the bottom pad; the loading mode of the component with the pin structure 100 of the present application does not need to use a tin wire and a special electric soldering tool such as an electric soldering iron, and some common tools can be used to repair and replace the pin structure 100. The pin structure 100 of the present application is a straight plug-in and easy-to-detach component pin structure, and the component with the pin structure 100 of the present application is easy to disassemble and install.

[0043] Specifically, the stop portion 40 and the first end surface of the preset component 200 are in surface contact, and the clamping piece 20 and the second end surface of the preset component 200 are in surface contact, so as to ensure the locking and fixing effect of the body assembly 1 and the preset component 200.

[0044] Optionally, the hole wall of the connecting hole 210 is a metal wall surface.

[0045] In the embodiment, the clamping portions 30 are multiple, and the multiple clamping portions 30 are sequentially arranged on the body assembly 1 in the penetrating direction of the body assembly 1; at least part of the multiple clamping portions 30 are arranged on the part of the body assembly 1 exposed outside the connecting hole 210; the stop portion 40 is selectively clamped with one of the multiple clamping portions 30, and the clamping portion 30 clamped with the stop portion 40 is necessarily arranged on the part of the body assembly 1 exposed outside the connecting hole 210. Among them, the clamping portion 30 selected by the stop portion 40 is the clamping portion 30 with which the stop portion 40 can abut against the first end surface of the preset component 200 while the stop portion 40 is clamped with the clamping portion 30.

[0046] In the specific implementation process, the position of the stop portion 40 in the axial direction of the connecting hole 210 is manually adjusted according to the axial length of the connecting hole 210, so as to make the stop portion 40 select a suitable clamping portion 30 for clamping; that is, the stop portion 40 moves in the direction from the first end to the second end of the body assembly 1 until the stop portion 40 abuts against the first end surface of the preset component 200.

[0047] Specifically, the preset component 200 is a plate structure, and the plate thickness direction of the preset component 200 is the same as the axial direction of the connecting hole 210; therefore, the position of the stop portion 40 in the axial direction of the connecting hole 210 is manually adjusted according to the plate thickness of the preset component 200.

[0048] Specifically, a part of the plurality of clamping portions 30 can be located in the connecting hole 210, and the clamping portion 30 located in the connecting hole 210 is in contact with the hole wall of the connecting hole 210, which is beneficial to increase the stability between the body assembly 1 and the preset component 200.

[0049] In the embodiment, the clamping portion 30 closest to the device body 90 among all the clamping portions 30 is the outermost clamping portion; the stop portion 40 has a clamping hole, the stop portion 40 is sleeved on the body assembly 1 through the clamping hole, and the hole wall of the clamping hole has a gap with the body assembly 1. When the stop portion 40 is in the initial state, the stop portion 40 is located on the side of all the clamping portions 30 away from the clamping piece 20, i.e., the stop portion 40 is located on the side of the outermost clamping portion away from the clamping piece 20, and since the hole wall of the clamping hole has a gap with the body assembly 1, the stop portion 40 can move in the direction from the first end to the second end of the body assembly 1 or in the direction from the second end to the first end of the body assembly 1 between the outermost clamping portion and the device body 90. By moving the stop portion 40 in the direction from the first end to the second end of the body assembly 1, the stop portion 40 is changed to the clamping state of clamping cooperation with the clamping portion 30. That is, after the stop portion 40 is selected to clamping cooperate with any one of the clamping portions 30, the stop portion 40 can only move in the direction close to the preset component 200, and cannot move in the direction close to the device body 90.

[0050] Optionally, the stop portion 40 is made of metal.

[0051] Optionally, the stop portion 40 is a ring body structure, and the intermediate hole surrounded by the stop portion 40 is a clamping hole.

[0052] In this embodiment, the first setting form of the clamping portion 30 is: the clamping portion 30 is an annular structure arranged around the first axis, the clamping portion 30 forms a middle hole, and the extension direction of the first axis is the same as the penetration direction of the main body component 1; along the axial direction of the clamping portion 30, the clamping portion 30 has a first end and a second end arranged opposite to each other; the direction from the first end to the second end of the clamping portion 30 is the same as the direction from the first end to the second end of the main body component 1; the inner wall of the clamping portion 30 is the hole wall of its middle hole; the clamping portion 30 is sleeved on the outer side of the main body component 1 through the middle hole, the inner wall of the first end of the clamping portion 30 is fixedly connected to the main body component 1, and the second end of the clamping portion 30 is a free end; that is, when there is no external force, the clamping portion 3 0 is spaced from the main body component 1 by the inner wall of the second end of the clamping portion 30; in the direction from the first end to the second end of the clamping portion 30, the outer periphery of the cross section of the clamping portion 30 perpendicular to the distribution direction from the first end to the second end thereof gradually increases, so that when the stopper 40 moves in the direction from the first end to the second end of the main body component 1, the hole wall of the clamping hole slides along the outer peripheral surface of the clamping portion 30; and after the stopper 40 slides over the second end of the clamping portion 30, the stopper 40 abuts against the inner wall surface of the clamping portion 30, thereby realizing the clamping fit between the stopper 40 and the clamping portion 30, and realizing that the stopper 40 cannot move in the direction from the second end to the first end of the main body component 1, but can only move in the direction from the first end to the second end of the main body component 1.

[0053] Specifically, when the outer circumference of the cross section of the clamping portion 30 perpendicular to the distribution direction from the first end to the second end gradually increases from the first end to the second end of the clamping portion 30, the outer circumference of the cross section of the clamping portion 30 perpendicular to the distribution direction from the first end to the second end gradually increases. Alternatively, when the cross section of the clamping portion 30 perpendicular to the distribution direction from the first end to the second end is circular, the diameter of the cross section of the clamping portion 30 perpendicular to the distribution direction from the first end to the second end gradually increases from the first end to the second end of the clamping portion 30.

[0054] In this embodiment, the second arrangement form of the clamping portion 30 is: the clamping portion 30 includes a plurality of clamping segments 31 arranged at intervals along the circumference of the body assembly 1 .

[0055] For each clamping segment 31: along the penetration direction of the main body component 1, the clamping segment 31 has a first end and a second end that are relatively arranged; the direction from the first end to the second end of the clamping segment 31 is the same as the direction from the first end to the second end of the main body component 1. The first end of the clamping section 31 is fixedly connected to the main body component 1, and the second end of the clamping section 31 is a free end; that is, when there is no external force, the inner wall of the second end of the clamping section 31 is spaced apart from the main body component 1; from the first end to the second end of the clamping section 31, the outer wall surface of the clamping section 31 gradually moves away from the main body component 1, so that when the stop part 40 moves in the direction from the first end to the second end of the main body component 1, the hole wall of the clamping hole slides along the outer wall surfaces of the multiple clamping sections 31 of the clamping part 30; and when the stop part 40 slides over the second ends of the multiple clamping sections 31 of the clamping part 30, the stop part 40 and the inner wall surfaces of the multiple clamping parts 30 of the clamping part 30 are all in contact, thereby realizing the clamping fit between the stop part 40 and the clamping part 30, and realizing that the stop part 40 cannot move in the direction from the second end to the first end of the main body component 1, but can only move in the direction from the first end to the second end of the main body component 1.

[0056] It should be noted that the circumference of the body component 1 is arranged around the second axis, and the extension direction of the second axis is the same as the penetration direction of the body component 1.

[0057] Specifically, the engaging section 31 is also called an outer chamfer or a barb structure.

[0058] For example, Figures 3 to 5 The stopper 40 in the middle can only move downwards but cannot move upwards.

[0059] In this embodiment, the latching member 20 includes a plurality of latching portions 21, which are spaced apart along the circumference of the connecting hole 210. Each latching portion 21 is movably disposed at the second end of the body assembly 1 to have a latching state and a retracted state. When each latching portion 21 is in the retracted state, the latching member 20 is in the retracted state. When at least two latching portions 21 are in the latching state, the latching member 20 is in the latching state. All latching portions 21 in the latching state are configured to abut against the second end surface of the preset component 200.

[0060] Preferably, when each of the blocking portions 21 is in the blocking state, the blocking member 20 is in the blocking state.

[0061] Specifically, multiple locking portions 21 are arranged in one-to-one correspondence with multiple third axes; each locking portion 21 is rotatably arranged around the corresponding third axis between a locking state and a retracted state; the extension direction of each third axis is perpendicular to the penetration direction of the main body component 1.

[0062] Optionally, the rotation angle of the blocking portion 21 between the blocking state and the retracted state is 90 degrees.

[0088] Step S11: The blocking member 20 of the pin structure 100 of the connector is retracted. Specifically, the plurality of blocking portions 21 of the blocking member 20 are all retracted.

[0089] Step S12 : Pass the blocking member 20 through the connection hole 210 of the preset component 200 , and insert the main body component 1 of the pin structure 100 into the connection hole 210 ; at this time, the first end of the main body 10 is located outside the connection hole 210 .

[0102] When disassembling the pin of the traditional component, the phenomenon that the solder pad is detached due to the pin contact surface is not completely detached from the component occurs; the pin structure 100 of the application does not have such a problem.

[0104] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects:

[0105] In the pin structure 100 provided by the present application for cooperating with the preset component 200, the preset component 200 has a connecting hole 210; along the axial direction of the connecting hole 210, the preset component 200 has oppositely arranged first and second ends; the connecting hole 210 penetrates the first and second end faces of the preset component 200; the pin structure 100 includes a body assembly 1, a stop portion 40 and a clamping piece 20, the body assembly 1 is used to be arranged in the connecting hole 210; along the arrangement direction of the body assembly 1, the body assembly 1 has oppositely arranged first and second ends; the arrangement direction of the body assembly 1 is parallel or identical to the axial direction of the connecting hole 210; the first end of the body assembly 1 is located outside the connecting hole 210, and the first end of the body assembly 1 is used to be fixedly connected with the device main body 90; the clamping portion 30 is arranged on the part of the body assembly 1 exposed outside the connecting hole 210; the stop portion 40 is used to be clamped with the clamping portion 30, so that the stop portion 40 cannot move in the direction from the second end to the first end of the body assembly 1; the stop portion 40 is used to abut against the first end face of the preset component 200; the clamping piece 20 is movably arranged at the second end of the body assembly 1, so as to have a retracted state and a clamping state; when the clamping piece 20 is in the retracted state, the clamping piece 20 is used to pass through the connecting hole 210; when the clamping piece 20 is in the clamping state, the clamping piece 20 is bent outward relative to the body assembly 1, so as to abut against the second end face of the preset component 200.

[0106] In the specific implementation process, the orientations of the first end to the second end of the preset component 200 are the same as the orientations of the first end to the second end of the body assembly 1; along the axial direction of the connecting hole 210, the connecting hole 210 has oppositely arranged first and second ends; the orientations of the first end to the second end of the preset component 200 are the same as the orientations of the first end to the second end of the connecting hole 210.

[0107] The blocking member 20 of the pin structure 100 is in a retracted state; the pin structure 100 is then passed into the connecting hole 210 from the first end of the connecting hole 210 in a direction from the first end to the second end of the main body component 1, so that the blocking member 20 passes through the connecting hole 210, and the main body component 1 is passed into the connecting hole 210; the blocking member 20 is then bent outward relative to the main body component 1, so that the blocking member 20 is changed from the retracted state to the blocking state; and the blocking member 20 in the blocking state is aligned with the first end of the preset component 200. The two end faces are fixedly abutted; then the stop portion 40 is snap-fitted with the clamping portion 30, and the stop portion 40 is fixedly abutted with the first end face of the preset component 200; due to the snap-fitting action of the stop portion 40 and the clamping portion 30, the stop portion 40 cannot move in the direction from the second end to the first end of the main body component 1; and then under the joint abutment action of the stop portion 40 and the clamping member 20, the main body component 1 and the preset component 200 are locked and fixed, thereby realizing the fixed connection between the device body 90 and the preset component 200.

[0108] When the pin structure 100 is to be detached from the preset component 200, a cutting tool is used to cut the first end of the main body component 1 from the device body 90; then the latch 20 is retracted to change the latch 20 from the blocking state to the retracted state; then the pin structure 100 is detached from the connecting hole 210 along the direction from the second end to the first end of the main body component 1.

[0109] The pin structure 100 of the present application is a detachable pin structure, which solves the problem of inconvenient assembly and disassembly of components with pins in the prior art.
