Description

Technical Field

[0001] The utility model relates to the technical field of power plugs, and more specifically to a flip plug with stable connection. Background Art

[0002] In order to provide the appropriate power supply to the electrical appliance, a circuit board needs to be installed in the plug. The circuit board has a regulating circuit, and the input end of the regulating circuit is electrically connected to the plug through the contacts on the circuit board, and the output end of the regulating circuit is electrically connected to the connecting cable of the plug. At this time, when the plug and the socket are matched, the current can be transmitted from the plug to the regulating circuit, and the regulating circuit rectifies the current, converts it into a current that is compatible with the electrical appliance, and then transmits it to the electrical appliance through the cable.

[0003] At present, the plug can be electrically connected to the contact of the circuit board through a wire. However, when there are two plugs in the plug, two wires are required to respectively connect the two plugs to the corresponding contacts. At this time, when the two wires are respectively welded to the corresponding plugs and contacts, the operation process is relatively cumbersome, resulting in a relatively cumbersome assembly process of the plug.

[0004] In order to simplify the assembly process of the plug, in the prior art, a conductive spring is used to connect the plug pin and the contact point. In this case, the connection between the plug pin and the circuit board can be completed by inserting the circuit board into the housing of the plug and making the contact point of the circuit board abut against the conductive spring.

[0005] However, when the contact of the circuit board abuts against the conductive spring sheet, the end of the conductive spring sheet will be displaced in a certain direction due to the pressure, thereby causing the contact end of the conductive spring sheet and the pin to be displaced. The position of the pin is relatively fixed, resulting in a reduction in the contact area between the conductive spring sheet and the pin, and the current is hindered when passing through the contact point, which may even cause poor contact or a circuit breaker. Utility Model Content

[0006] In order to overcome the problem of existing conductive spring sheets, when the contact of the circuit board abuts against the conductive spring sheet, the end of the conductive spring sheet will be deflected in a certain direction due to pressure, thereby causing the contact end of the conductive spring sheet and the plug to deflect, while the position of the plug is relatively fixed, resulting in a reduction in the contact area between the conductive spring sheet and the plug, thereby causing the contact to be unstable. The utility model provides a flip plug with a stable connection.

[0007] The technical solution of the utility model is as follows:

[0008] A flip plug with stable connection includes a conductive spring sheet, the conductive spring sheet includes a plug-in portion, a hanging portion and an elastic contact portion, the hanging portion is arranged between the plug-in portion and the elastic contact portion, the plug-in portion is folded twice to be in a hook shape, and is used to abut against the contact of a circuit board, the hanging portion is folded at a first fold to form a first inclined surface that is hung on an external mounting support, the hanging portion and the plug-in portion are arranged opposite to each other, the hanging portion forms a stable support point at the mounting support, increases the deformation range of the plug-in portion and the circuit board, and reduces the deformation at the elastic contact portion.

[0009] The utility model according to the above scheme also includes a conductive pin and the mounting support, the two conductive pins are connected by a mounting portion, and are rotatably mounted on the mounting support by the mounting portion, and the second inclined surface formed by the elastic contact portion being folded at the second folding position is elastically supported by the outer shell of the plug, so that the elastic contact portion is stably connected to the conductive pin.

[0010] According to the above-mentioned solution of the utility model, an arc-shaped groove is provided on the mounting support, and a mounting space of the mounting portion is formed between the arc-shaped groove and the shell of the plug.

[0011] According to the utility model of the above scheme, a first slot body for the conductive pin to rotate is provided on the shell of the plug. When the plug is in use, the conductive pin is perpendicular to the shell of the plug. When the plug is not in use, the conductive pin can be rotated 90 degrees and placed in the first slot body.

[0012] According to the utility model of the above scheme, the mounting portion is provided with two limiting grooves, and the mounting support is provided with an elastic limiting portion, and the elastic limiting portion switches between the two limiting grooves so that the conductive pin switches between the use state and the non-use state.

[0013] According to the above-mentioned solution of the utility model, a stopper is provided in the middle of the two limiting grooves, and the stopper blocks the elastic limiting part from switching between the two limiting grooves, so that the conductive pin remains stable when in use or not in use.

[0014] According to the above-mentioned solution of the utility model, the mounting support is provided with a through slot, and one side of the through slot extends inwardly to form the elastic limiting portion.

[0015] According to the utility model of the above scheme, a hanging hole is provided on the mounting support, and a hanging platform is provided on one side of the hanging hole, so that the second inclined surface passes through the hanging hole and is hung on the hanging platform, thereby realizing stable installation of the conductive spring sheet.

[0017] According to the above-mentioned solution of the utility model, the conductive spring piece is an integrally formed structure.

[0018] The utility model according to the above scheme has the beneficial effect that the plug-in part of the utility model is in the shape of a barb. When the circuit board is plugged into the plug-in part in the shape of a barb, the plug-in part will be deformed along a predetermined direction after receiving pressure from the circuit board.

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present utility model are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices. Terms such as "setting" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "bottom", etc. are based on the directions or positions shown in the drawings, which are only for the convenience of description and cannot be understood as limitations on the present technical solution.

[0033] It should be noted that when the contact of the circuit board abuts against the conductive spring sheet, the end of the conductive spring sheet will be displaced in a certain direction due to the pressure, thereby causing the contact end of the conductive spring sheet and the pin to be displaced. The position of the pin is relatively fixed, resulting in a reduction in the contact area between the conductive spring sheet and the pin, and the current is hindered when passing through the contact point, which may even cause poor contact or a circuit breaker.

[0034] like Figure 1-Figure 5 As shown, this embodiment provides a flip plug with stable connection, the plug part 33 is in the shape of a barb, and the plug part 33 is in the shape of a barb after being folded twice. The barb design allows the conductive spring piece 30 to be more firmly fixed when inserted into the corresponding slot or contact point of the circuit board, which not only reduces the risk of falling off due to vibration or external force, but also enhances the stability of the overall connection. The barb structure can also increase the contact area between the conductive spring piece 30 and the contact point. This means that there are more paths for current to pass through, thereby reducing resistance and improving conduction efficiency.

[0035] When the circuit board is plugged into the "hook-shaped" plug-in portion 33, the plug-in portion 33 will be deformed in a predetermined direction after receiving pressure from the circuit board. The hanging portion 32 is hung on the external mounting bracket 40 to provide a stable support point for the deformation of the plug-in portion 33.

[0036] Specifically, it includes a conductive spring piece 30, which includes a plug-in portion 33, a hanging portion 32 and an elastic contact portion 31. The hanging portion 32 is arranged between the plug-in portion 33 and the elastic contact portion 31. The plug-in portion 33 is folded twice to be in a hook shape, which is used to abut against the contact of the circuit board to ensure stable current transmission. The hanging portion 32 is hung at the external mounting support 40 through a first inclined surface 322 formed after the hanging portion 32 is folded at the first folding position 321. The hanging portion 32 and the plug-in portion 33 are arranged opposite to each other. The hanging portion 32 forms a stable support point at the mounting support 40, which increases the deformation range of the plug-in portion 33 and the circuit board to reduce the deformation at the elastic contact portion 31.

[0037] The hanging part 32 and the plug part 33 of the conductive spring 30 are arranged opposite to each other. When the plug part 33 is deformed, it abuts against the mounting support 40 with the hanging part 32, providing support for the deformation of the plug part 33. The deformable range of the plug part 33 is increased, and the installation space of the circuit board is increased at the same time. The deformation of the plug part 33 will not affect the contact between the elastic contact part 31 and the conductive pin 10. Not only the installation space of the circuit board is increased, making the layout of the circuit board more flexible and diverse, but also it is ensured that the deformation of the plug part 33 will not cause any influence on the contact between the elastic contact part 31 and the conductive pin 10.

[0038] In one embodiment, the flip plug with stable connection also includes a conductive pin 10 and a mounting support 40. The two conductive pins 10 are connected by a mounting portion 20 and are rotatably mounted on the mounting support 40 through the mounting portion 20. The second inclined surface 312 formed by the elastic contact portion 31 after being folded at the second folding portion 311 is elastically supported by the outer shell of the plug 1, so that the elastic contact portion 31 is stably connected to the conductive pin 10.

[0039] The two conductive pins 10 are connected by the mounting portion 20 and are rotatably mounted on the mounting support 40 through the mounting portion 20. The conductive pins 10 can be folded and stored in the plug 1 for easy carrying.

[0040] The second inclined surface 312 formed by the folded elastic contact portion 31 forms an elastic support with the shell of the plug 1, so that even if some vibration or shaking occurs during the plugging and unplugging process, the conductive spring 30 can maintain a close fit with the shell, thereby ensuring a stable connection with the conductive pin 10.

[0041] In one embodiment, an arc-shaped groove 41 is provided on the mounting support 40, and a mounting space for the mounting portion 20 is formed between the arc-shaped groove 41 and the outer shell of the plug 1. The bottom of the mounting portion 20 is arc-shaped, and the arc-shaped bottom of the mounting portion 20 cooperates with the arc-shaped groove 41 to reduce the friction during the rotation of the mounting portion 20.

[0042] In one embodiment, a first slot 50 for the conductive pin 10 to rotate is provided on the outer shell of the plug 1. When the plug 1 is in use, the conductive pin 10 is perpendicular to the outer shell of the plug 1. When the plug 1 is not in use, the conductive pin 10 can be rotated 90 degrees and placed in the first slot 50. The conductive pin 10 can be folded and stored in the first slot 50 of the plug 1, which is convenient to carry and avoids accidental damage that may be caused by the conductive pin 10 when not in use.

[0043] The mounting portion 20 is provided with two limiting grooves 21 , and the mounting support 40 is provided with an elastic limiting portion 42 . The elastic limiting portion 42 switches between the two limiting grooves 21 , thereby controlling the conductive pin 10 to switch between the use state and the non-use state.

[0044] A stopper 22 is provided in the middle of the two limit slots 21, and the stopper 22 blocks the elastic limiter 42 from switching between the two limit slots 21, so that the conductive pin 10 remains stable when in use or not in use. The purpose of providing the stopper 22 is to block the elastic limiter 42 from switching between the two limit slots 21 at will, thereby ensuring that the conductive pin 10 does not shake when in use, i.e., when inserted into a socket for power transmission, and does not accidentally pop out when in non-use, i.e., when stored.

[0045] The mounting bracket 40 is provided with a through slot 43, and one side of the through slot 43 extends inward to form an elastic limiting portion 42. Specifically, when the elastic limiting portion 42 switches between the two limiting slots 21, it will be blocked by the blocking portion 22. After the conductive pin 10 is rotated with a little force, the elastic limiting portion 42 will move downward, and after being separated from the blocking portion 22, it will move from one limiting slot 21 to the other limiting slot 21, thereby realizing the switching of the conductive pin 10 between the use state and the non-use state.

[0046] In one embodiment, the mounting bracket 40 is provided with a hanging hole 44, and the mounting bracket 40 is provided with a hanging platform 45 on one side of the hanging hole 44, so that the second inclined surface 312 passes through the hanging hole 44 and is hung on the hanging platform 45, thereby realizing stable installation of the conductive spring 30. The setting of the hanging hole 44 allows the hanging portion 32 of the conductive spring 30 to pass smoothly, and the hanging platform 45 provides a solid support point, so that the second inclined surface 312 can be stably hung thereon.

[0047] The conductive pin 10 has a first extension portion 11 that passes through the mounting portion 20 and can be elastically contacted and connected with the conductive spring sheet 30. The first extension portion 11 can be elastically contacted and connected with the conductive spring sheet 30.

[0048] The conductive spring piece 30 is an integrally formed structure, which enhances the overall strength of the conductive spring piece 30 and improves its durability and reliability.

[0049] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0050] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
