[0002] To connect two or more opposing circuit boards, generally, wires are soldered or male and female conductive terminals are mated to achieve conduction.
[0003] When using male and female conductive terminals, the corresponding terminal interfaces need to be soldered on the PCB board. The terminal interfaces are relatively large, and the volume of the produced PCB board will also increase;
[0004] In addition, the use of terminal interfaces involves welding and the use of leads on the PCB board. It is not difficult to see that this traditional connection method has the defects of large size and high cost. Utility Model Content
[0005] In order to solve the above problems, the utility model provides a simple conductive connection structure, which utilizes gold fingers on a conductive plate to achieve mutual connection, saves the use of leads, and is effectively optimized in terms of volume and cost.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A simple conductive connection structure includes at least two conductive plates, each of which has an electrical contact area for communication or conduction. At least one conductive plate is set by warping deformation, so that the electrical contact area of the conductive plate is offset against the electrical contact area of another conductive plate under the elastic force after the warping deformation, thereby forming the transmission of electrical signals. The elastic force generated by the warping deformation of the conductive plate makes the electrical contact areas of the two closely connected to achieve the reliability of conduction.
[0008] Furthermore, the simple conductive structure also includes an auxiliary part fixedly connected to at least one conductive plate, and the warping deformation is formed by the auxiliary part abutting against another conductive plate; or the auxiliary parts connected to the conductive plates abut against each other to achieve abutment conduction between the conductive plates.
[0009] Furthermore, the auxiliary part is a link part, in which one conductive plate is fixedly mounted on the link part with a gap provided between the conductive plate and the link part; another conductive plate is inserted in the gap so that the conductive plate fixedly mounted on the link part is warped and deformed, thereby achieving an abutting connection between the two conductive plates.
[0010] Furthermore, the auxiliary parts are a linking part and a shell; one of the conductive plates is mounted on the linking part, and the other conductive plate is mounted on the shell; the shell is fixedly connected to the linking part so that the two conductive plates are offset against each other to produce warping deformation.
[0011] Furthermore, the electrical contact area of at least one conductive plate includes at least two first electrical connection portions that are spaced apart and are staggered during electrical contact, so that the electrical contact area is held in a clamped posture on the electrical contact area of another conductive plate.
[0012] Furthermore, the electrical contact area of at least one conductive plate includes at least three first electrical connection portions which are spaced apart and are staggered during electrical contact, so that the electrical contact area is held in a clamped posture on the electrical contact area of another conductive plate.
[0013] Furthermore, the electrical contact area on the other conductive plate includes at least two second electrical connection parts that are spaced apart from each other. After the second electrical connection parts come into contact with the first connection parts, they are clamped on the first connection parts by warping.
[0014] Furthermore, the electrical contact areas are interlocked with each other; the electrical contact areas are respectively provided with grooves and convex parts that match each other, and the two electrical contact areas are interlocked with each other through the engagement of the grooves and the convex parts.
[0015] Furthermore, there are a plurality of grooves and protrusions, so that the grooves and protrusions are arranged in a grid shape; at least one of the conductive plates is a PCB board. In this patent, the conductive plate is preferably a PCB board, and there may also be a conductive plate made of other materials with a gold finger connection structure.
[0016] This patent also provides a lighting structure, including a light-emitting body, a light-transmitting plate, and a connecting part; the light-emitting body and the connecting part are both provided with a conductive plate, and the conductive plate is connected by the aforementioned simple conductive connection structure; the light-emitting body also includes a light source mounted on the conductive plate on the light-emitting body, and the light source emits light into the light-transmitting plate to illuminate the pattern set on the surface of the light-transmitting plate.
[0017] Furthermore, a groove structure is reserved on the outer side of the light-emitting body, and the light-emitting body is inserted into the interior of the link and is connected to the snap-fitting part in the link; the snap-fitting part has a W shape with hooks at both ends, which are connected to the groove structure by snap-fitting.
[0018] The beneficial effects of the utility model are as follows: the extrusion contact between the two electrical contact areas on the PCB board will cause slight deformation of each other. This deformation maintains the positions of the two gold fingers in an upward and downward misaligned interference relationship, so that the two gold fingers are in close contact, thereby eliminating the use of leads, terminal connectors, etc., saving parts and components, and greatly reducing production costs; in addition, the elimination of the terminal interface optimizes the overall thickness size, and the reduction in thickness can make the product more compact. The conductive plate is a sheet plate, and when it is slightly deformed in the vertical direction of the front side, the sheet plate has a rebound force, which ensures the reliability of the gold finger contact.

[0032] In the specification, references to "one embodiment," "an embodiment," or "some embodiments" mean that a particular feature, structure, or element described with reference to the embodiment is included in at least one embodiment of the subject matter being described. Thus, the phrases "in one embodiment," "in an embodiment," or "in some embodiments" in the specification do not necessarily refer to the same embodiment or embodiments. The particular features, structures, or elements may be further combined in any embodiment in a suitable manner.
[0033] Example 1.
[0034] like Figure 1 As shown, a simple conductive connection structure includes at least two conductive plates 1, each of which has an electrical contact area for communication. At least one conductive plate is set by warping deformation, so that the electrical contact area of the conductive plate 1 is offset against the electrical contact area on another conductive plate 1 under the elastic force after the warping deformation, thereby forming the transmission of electrical signals. The elastic force generated by the warping deformation of the conductive plate 1 makes the electrical contact areas of the two plates closely connected to achieve the reliability of conduction. Specifically, Figure 1 As shown, the conductive plate 1 can be specifically a PCB circuit board.
[0035] Specifically, the simple conductive structure described in this embodiment also includes an auxiliary part fixedly connected to at least one conductive plate, and the warping deformation is formed by the auxiliary part abutting against another conductive plate; or the auxiliary parts connected to the conductive plates abut against each other to achieve abutment conduction between the conductive plates.
[0036] As one of the implementation methods Figure 2 As shown, the auxiliary member is a link member 20, wherein one conductive plate 12 is fixedly mounted on the link member 20, and a gap is provided between the conductive plate 12 and the link member 20; another conductive plate 11 is inserted into the gap so that the conductive plate fixedly mounted on the link member is warped and deformed, thereby achieving abutment connection between the two conductive plates. Specifically, the thickness of the conductive plate 11 is greater than the gap, so that the conductive plates 11 and 12 are abutted and conductive.
[0037] As another preferred embodiment, see Figure 3 The auxiliary parts are a link 200 and a housing 201; one of the conductive plates 100 is mounted on the link 200, and the other conductive plate 101 is mounted on the housing 201; the housing 201 is fixedly connected to the link 200, so that the two conductive plates are offset against each other to produce a warping deformation. This embodiment mainly provides a torsional pressure to achieve warping through the auxiliary parts.
[0038] As a new implementation, the advantage of this implementation is that no auxiliary parts are needed to provide pressure to achieve the mutual resistance of the conductive plates. Specifically, at least two electrical connection parts capable of reverse warping and deformation to clamp the other conductive plate are arranged on one conductive plate. Specifically, Figure 4 In the connection structure shown, the electrical contact area of at least one conductive plate 1000a includes at least two first electrical connection parts 1001 spaced apart and staggered during electrical contact, so that the electrical contact area is held in a clamped position on the electrical contact area of another conductive plate 1000b. As a further solution, the electrical contact area of at least one conductive plate 1000a includes at least three first electrical connection parts 1001 spaced apart and staggered during electrical contact, so that the electrical contact area is held in a clamped position on the electrical contact area of another conductive plate 1000b. As a more preferred solution, Figure 5 As shown, a first electrical connection portion 1003 is arranged at intervals on one conductive plate 1000c, and the electrical contact area on the other conductive plate 1000d includes at least two (preferably three) second electrical connection portions 1004 arranged at intervals. After the second electrical connection portion 1004 contacts the first connection portion 1003, it is clamped on the first connection portion 1003 by warping. The two conductive plates are correspondingly provided with multiple connection portions, which can make the relative amplitude of the warping larger, more convenient to install, and more stable.
[0039] like Figure 11-12 As shown, a further implementation method is that the electrical contact areas are interlocked; the electrical contact areas are respectively provided with mutually matching grooves 3a and protrusions 3b, which are connected by the engagement of the grooves 3a and the protrusions 3b, so that the two electrical contact areas are interlocked with each other. There are a plurality of grooves 3a and protrusions 3b, so that the distribution of the grooves 3a and the protrusions 3b is arranged in a grid shape; at least one of the conductive plates is a PCB board. In this patent, the conductive plate is preferably a PCB board, and there can also be a conductive plate made of other materials with a gold finger connection structure.

Figure 6 The structure shown specifically includes the connection structure 2, the luminous body 1, and the light-transmitting part 3 described in Example 1; the structure can have multiple of the above units combined to achieve the required size or shape. The connection structure 2 includes a link 20, which is mainly used to connect and electrically conduct the unit composed of the light-transmitting part and the luminous body 1; the luminous body 1 is mainly used to reflect light into the light-transmitting part 3, so that the pattern on the surface of 3 shines, achieving a decorative effect.
[0042] like Figure 7-10 As shown, the linking member 20 and the light-emitting body 1 are internally interconnected, and the light-emitting body 1 includes a first conductive plate 11 and a light source 111; a second conductive plate 12, and the first conductive plate 11 and the second conductive plate 12 are connected using any one of the connection methods in Example 1 to realize the lighting product.
[0043] Furthermore, a slot structure 101 is reserved on the outside of the light-emitting body 1, and the light-emitting body 1 is inserted into the interior of the link 20 and is connected with the clip 201 in the link 20; the clip 201 has a W shape, and hooks 2011 are provided at both ends, and are connected with the slot structure 101 through the hooks 2011. In this way, the assembly, electrical connection and subsequent related control of the lighting are realized.
