Description
Technical Field
[0001] This utility model belongs to the field of terminal block technology, and relates to a solderless terminal block and an LED light using a solderless terminal block. Background Technology
[0002] Terminal blocks, as a type of connector, are an important component in the electrical industry. They are mainly used to connect wires and are widely used in daily life.
[0003] Traditional terminal blocks available on the market primarily connect wires by welding. This process requires manual welding by operators, which is not only cumbersome, but the connection strength between the terminal and the wire is also largely determined by the quality of the manual welding. Over a long period of welding, the quality of manual welding inevitably declines, resulting in a lack of quality assurance. Utility Model Content
[0004] To solve the implementation technical problems, the present invention adopts the following technical solution:
[0005] A solderless wire terminal includes: a terminal substrate, one end of which is formed with two sets of folded riveting portions arranged along its length direction. The two sets of folded riveting portions are divided into copper wire riveting portions and lamp bead riveting portions according to different working types.
[0006] The two sets of folding riveting parts have the same structure, both being "U"-shaped clamping structures with outward-extending coiled pressing sheet structures on both sides. Through the cooperation of the two sets of coiled pressing sheets, the riveting cavity with a semi-enclosed structure is formed in the folding riveting part, and the coiled pressing sheet can be bent into the riveting cavity to realize the riveting work.
[0007] As a further embodiment of this utility model, the inner end face of the folding and riveting part is formed with reinforcing ribs arranged along its width direction.
[0008] As a further embodiment of this utility model: the terminal substrate and the rolled sheet are integrally formed structures, both made of copper material.
[0009] An LED lamp using solderless terminals includes: LED beads and at least two connecting wires for connecting the LED beads to power.
[0010] The connecting wires are divided into positive wires and negative wires according to their polarity, and are respectively matched with the two pins of the LED light bead;
[0011] The connection between the power supply wire and the LED lamp bead's support foot is achieved through a terminal block. The terminal block is riveted to the core of the power supply wire through a copper wire riveting part, while the lamp bead riveting part is riveted to the LED lamp bead's support foot, thus achieving a solderless connection between the power supply wire and the LED lamp bead.
[0012] An isolation post is provided between the two sets of terminals to separate them and prevent short circuits.
[0013] It also includes: a lamp housing, which consists of a fixed housing and a lamp bead cover, and protects the LED beads, isolation posts, wiring terminals and the power connection terminals connected to the wiring terminals.
[0014] As a further embodiment of this utility model: the isolation column has an "I" shaped structure, and the two sides of the isolation column have limiting grooves for embedding wiring terminals.
[0015] The beneficial effects of this utility model are as follows: By setting a folding and riveting part with a "U"-shaped clamping structure on the terminal body, the connection between the wire and the lamp bead is achieved by riveting, which replaces the traditional welding wiring method. The overall wiring process is simpler and more efficient, and the overall processing cost is lower. The wiring structure is more stable and better meets the current wiring processing needs of the industry. Attached Figure Description

It should be understood that this application is not limited to the exemplary embodiments disclosed herein. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0024] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0025] In the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0026] This utility model provides a reference. Figures 1-3 In this embodiment of the utility model, a solderless wire terminal includes: a terminal substrate 2, one end of which is formed with two sets of folded riveting parts 1 arranged along its length direction. The two sets of folded riveting parts 1 are divided into a copper wire riveting part 1A and an LED bead riveting part 1B according to different working types. During wiring, the copper wire riveting part 1A is riveted to the wire core of the power connecting wire 4, while the LED bead riveting part 1B is riveted to the support leg 31 of the LED bead 3, thereby realizing the solderless connection between the power connecting wire 4 and the LED bead 3.
[0027] Both sets of folding and riveting parts 1 have the same structure, both being "U"-shaped clamping structures with outwardly extending coiled pressing sheets 11 on both sides. Through the cooperation of the two sets of coiled pressing sheets 11, a semi-enclosed riveting cavity 12 is formed in the folding and riveting part 1. During the actual wiring process, the core of the connecting wire 4 or the support leg 31 of the LED bead 3 is pre-installed into the riveting cavity 12. Then, the coiled pressing sheets 11 are pressed into the riveting cavity 12. The coiled pressing sheets 11 and the terminal substrate 2 cooperate to form an enclosing structure, covering the core of the connecting wire 4 or the support leg 31 of the LED bead 3, thus realizing the riveting work between the terminal and the connecting wire 4 or the LED bead 3.
[0028] Furthermore, during the actual wiring process, the connection tension between the terminal and the wire core of the power-connecting wire 4 or the support leg 31 of the LED bead 3 can be further improved by nesting a plastic shell outside the terminal connection position.
[0029] Furthermore, the inner end face of the folded riveting part 1 is formed with reinforcing ribs 13 arranged along its width direction. The reinforcing ribs 13 improve the overall structural tensile strength of the folded riveting part 1 and enhance the connection strength of the overall connection structure.
[0030] Preferably, the terminal substrate 2 and the rolled sheet 11 are integrally formed structures, both made of copper material, which has good electrical conductivity and extremely high toughness, and can well meet the processing requirements of bending and riveting wires.
[0031] like Figure 3-7 As shown, in this embodiment of the present invention, a solderless LED lamp is also provided, which is based on the above-mentioned solderless LED lamp to realize the structural arrangement, including: LED lamp beads 3 and at least two connecting wires 4 for connecting the lamp beads to power.
[0032] The power-connecting wire 4 is divided into a positive wire 41 and a negative wire 42 according to the different polarities. The power-connecting wire 4 is either a high-voltage wire or a low-voltage wire.
[0033] When the connecting wire 4 is a high-voltage wire, there are two connecting wires 4, corresponding to the positive and negative terminals 31 of the LED bead 3;
[0034] When the connecting wire 4 is a low-voltage wire, there are four connecting wires 4, which correspond to the positive and negative terminals 31 of the LED beads 3 in pairs.
[0035] The connection between the power supply wire 4 and the support leg 31 of the LED bead 3 is achieved through the terminal 7. The terminal 7 is riveted to the wire core of the power supply wire 4 through the copper wire riveting part 1A, while the LED bead riveting part 1B is riveted to the support leg 31 of the LED bead 3, thereby achieving a solderless connection between the power supply wire 4 and the LED bead 3.
[0036] To prevent short circuits between the positive and negative terminals, an isolation post 5 is provided between the two sets of terminals 7. The isolation post 5 has an "I" shaped structure, and the two sides of the isolation post 5 are available for the terminal 7 to be inserted into the limiting groove 51. The isolation post 5 is used to limit the positive and negative terminals and isolate them.
[0037] Furthermore, the connection positions of the connecting wire 4, the support 31, the isolation post 5, the connecting wire 4, and the terminal 7 are covered with heat shrink tubing (not shown in the figure). The heat shrink tubing fixes the position of the isolation post 5 to ensure that the positive and negative poles do not come into contact, and at the same time facilitates the subsequent lamp assembly work.
[0038] The LED lamp in this embodiment also includes: a lamp body shell 5, which is composed of a fixed shell 5 and an LED bead cover 6. The lamp body shell 5 forms a sealed protective structure, protecting the LED bead 3, the isolation column 5, the wiring terminal 7 and the power connection terminal connected to the wiring terminal 7. This can achieve the protection effect of the component structure at this position, such as preventing breakage and waterproofing, and can realize the protection of the LED lamp.
[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
