Description
Technical Field
[0001] This invention relates to the field of electrical technology, and in particular to a terminal block. Background Technology
[0002] During the wiring process of LED light strips, it is often necessary to change the route of the wires or light strips to better adapt to the requirements of the actual installation environment. For this reason, terminal blocks that can change the route of wires or light strips have emerged.
[0003] Typically, the housing of a terminal block is made of insulating plastic, produced through injection molding. To achieve conductivity, a conductive metal strip is placed on the housing. Integrating the housing and conductive metal strip into a single injection mold can improve the bonding strength and insulation performance. However, while this method yields good results, the ends of the conductive metal strip are prone to breakage during crimping with wires or LED strips, rendering the entire terminal block unusable and resulting in significant material waste.
[0004] How to optimize the structure of the terminal block and modularize the components based on the integrated injection molding process? On the one hand, this invention eliminates the need for welding operations, allowing end users to flexibly assemble it into various connection forms according to actual needs. Furthermore, the splicing length can be further adjusted by replacing the cover assembly, achieving compatibility and expansion for products of different sizes. On the other hand, when some components are damaged, users can replace the corresponding modules without discarding the entire terminal block, thereby reducing material waste and promoting resource conservation and sustainable use. This is the technical problem that needs to be solved. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a terminal block that adopts a modular design and is based on integrated injection molding. Users can flexibly assemble it into various shapes such as L-shape and T-shape without welding, and the length can be adjusted by changing the cover to be compatible with different sizes.

On one hand, this eliminates the need for welding, allowing end users to flexibly assemble the terminal block into various connection configurations according to their needs, such as L-shaped (lamp-to-lamp, lamp-to-wire, wire-to-wire) or T-shaped (lamp-to-lamp, lamp-to-wire, wire-to-wire) configurations. Furthermore, by replacing the cover assembly, the splicing length can be further adjusted, achieving compatibility and expansion for products of different sizes, significantly improving the ease of use and connection reliability.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0021] Please refer to the following: Figures 1 to 3 This invention discloses a terminal block 10, comprising: a base 100, a first crimping latch 200, and a second crimping latch 300. For example... Figure 10 As shown, in this embodiment, the first crimping buckle 200 is used to connect with the wire 20 or the LED light strip 30, and the second crimping buckle 300 is used to connect with the wire 20 or the LED light strip 30.
[0022] like Figure 4 and Figure 5 As shown, the base 100 has a first limiting groove 110 and a second limiting groove 120, and a first conductive sheet 400 and a second conductive sheet 500 (e.g., ...) are embedded in the base 100. Figure 5 and Figure 7 As shown), the first conductive sheet 400 and the second conductive sheet 500 are connected between the first limiting groove 110 and the second limiting groove 120. It can be understood that the base 100, the first conductive sheet 400, and the second conductive sheet 500 are integrally injection molded by an injection molding machine. The two ends of the first conductive sheet 400 are exposed at the groove walls of the first limiting groove 110 and the second limiting groove 120, respectively, and the two ends of the second conductive sheet 500 are exposed at the groove walls of the first limiting groove 110 and the second limiting groove 120, respectively.
[0023] like Figure 4 As shown, a first puncture needle 600 and a second puncture needle 700 are detachably provided on the first limiting groove 110, and a third puncture needle 800 and a fourth puncture needle 900 are detachably provided on the second limiting groove 120.
[0024] like Figure 4 and Figure 5 As shown, the first puncture needle 600 and the third puncture needle 800 are electrically connected through the first conductive sheet 400, and the second puncture needle 700 and the fourth puncture needle 900 are electrically connected through the second conductive sheet 500.
[0025] like Figure 6 As shown, it should be noted that the first puncture needle 600 includes a first needle body 610 and a first positioning block 620 wrapped around one end of the first needle body 610. The first needle body 610 is partially exposed on the sidewall of the first positioning block 620, thus forming a first contact point 601. The first positioning block 620 is housed in a first limiting groove 110, and the first contact point 601 abuts against one end of the first conductive sheet 400. It can be understood that the first needle body 610 and the first positioning block 620 are integrally injection molded by an injection molding machine. In this embodiment, a V-groove 630 is formed at the end of the first needle body 610 away from the first positioning block 620, and a needle tip 640 is formed at the opening of the V-groove 630.
[0026] like Figure 4 As shown, in this invention, the first needle body 600, the second puncture needle 700, the third puncture needle 800, and the fourth puncture needle 900 have the same structure. It can be understood that the second puncture needle 700, the third puncture needle 800, and the fourth puncture needle 900 also have a needle body and a positioning block, and are also integrally injection molded using an injection molding machine.
[0027] like Figure 3 As shown, the first crimping buckle 200 has a first through hole 210, and the first crimping buckle 200 is snapped onto the base 100, and the first puncture needle 600 and the second puncture needle 700 pass through the first through hole 210; the second crimping buckle 300 has a second through hole 310, and the second crimping buckle 300 is snapped onto the base 100, and the third puncture needle 800 and the fourth puncture needle 900 pass through the second through hole 310.
[0028] The following describes how to use the wiring terminal 10 of the above structure: like Figure 10 As shown, one of the wires 20 or one of the LED light strips 30 is connected to the first crimping buckle 200, and the other wire 20 or the other LED light strip 30 is connected to the second crimping buckle 300. The first puncture needle 600 and the second puncture needle 700 are inserted into the first limiting groove 110, and the third puncture needle 800 and the fourth puncture needle 900 are inserted into the second limiting groove 120. Thus, the first contact 601 on the first puncture needle 600 abuts against one end of the first conductive sheet 400. Similarly, the contacts of the other puncture needles also abut against the end face of the conductive sheet. In this way, the first puncture needle 600 and the third puncture needle 800 are electrically connected through the first conductive sheet 400, and the second puncture needle 700 and the fourth puncture needle 900 are electrically connected through the second conductive sheet 500. like Figure 10 As shown, a first crimping buckle 200 connected to a wire 20 or an LED light strip 30 is crimped onto a first piercing needle 600 and a second piercing needle 700 in a first limiting groove 110. During the crimping process, the first piercing needle 600 and the second piercing needle 700 pierce the wire 20 or the LED light strip 30, and the first piercing needle 600 and the second piercing needle 700 are electrically connected to the internal conductors of the wire 20 or the LED light strip 30. It should be noted that the base 100 and the first crimping buckle 200 are respectively provided with corresponding grooves and protrusions to form a snap-fit connection, so that the first crimping buckle 200 can be stably fastened to the base 100. Similarly, the second crimping buckle 300 connected to the wire 20 or LED light strip 30 is crimped onto the third piercing needle 800 and the fourth piercing needle 900 of the second limiting groove 120. During the crimping process, the third piercing needle 800 and the fourth piercing needle 900 pierce the wire 20 or LED light strip 30, and the third piercing needle 800 and the fourth piercing needle 900 are electrically connected to the internal conductor of the wire 20 or LED light strip 30. like Figure 10 As shown, it can be understood that the first crimping buckle 200 can be selectively connected to the wire 20 or the LED light strip 30, and the second crimping buckle 300 can also be selectively connected to the wire 20 or the LED light strip 30, which can form a variety of arrangements and combinations, such as: wires conducting to wires, LED light strips conducting to LED light strips, and wires conducting to LED light strips.
[0029] It should be noted that the crimping clips used to connect the wire 20 and the crimping clips used to connect the LED light strip 30 differ in their external structure (e.g., Figure 8 and Figure 9 As shown), but ultimately, the crimping clip needs to have a through hole to facilitate the puncture of the piercing needle. For example, the crimping clip used to connect the wire 20 has a split structure, consisting of an upper cover 21 and a lower cover 22 (as shown). Figure 8 As shown), the upper cover 21 and the lower cover 22 are flipped and fastened together to press the wire 20 tightly, and the wire length can be customized; for example, the crimping buckle used to connect the LED light strip 30 is an integrated structure 31 (as shown). Figure 9As shown, the LED light strip 30 can be threaded through the crimping buckle of the integrated structure.
[0030] The beneficial effects of the wiring terminal 10 of the above structure will be explained below: 1. The terminal block 10 is divided into multiple components (base 100, first crimping buckle 200, second crimping buckle 300, first puncture needle 600, second puncture needle 700, third puncture needle 800, and fourth puncture needle 900) to form a modular design. When a component is damaged, it can be flexibly replaced. In particular, during the crimping process, the puncture needle is easily bent or broken by the influence of uncertain forces. Once the puncture needle bends or breaks, it can be quickly pulled out of the groove for replacement, so as not to scrap the entire terminal block 10. 2. The base 100, the first conductive sheet 400, and the second conductive sheet 500 are integrally injection molded by an injection molding machine. Each puncture needle is also integrally injection molded by an injection molding machine. The puncture needles are then detachably placed in the corresponding limiting grooves, thereby realizing the electrical conduction of each component. Each component is injection molded separately, reducing the difficulty of mold design. Each component corresponds to each mold. 3. The terminal block 10 is divided into multiple components to form a modular design. The first crimping buckle 200 and the second crimping buckle 300 are arranged perpendicularly to each other, which facilitates the routing of wires during the wiring process, or forms an "L"-shaped design (such as...). Figure 10 As shown), or forming a "T" shaped design (such as... Figure 10 (as shown) 4. The first crimping buckle 200 can be selectively connected to the wire 20 or the LED strip 30, and the second crimping buckle 300 can also be selectively connected to the wire 20 or the LED strip 30, forming various arrangements and combinations, such as: wires conducting to wires, LED strips conducting to LED strips, and wires conducting to LED strips. This can adapt to various complex working conditions and form DIY designs (such as...). Figure 10 (as shown) 5. The first puncture needle 600, the second puncture needle 700, the third puncture needle 800, and the fourth puncture needle 900 are electrically connected to the wire 20 or the LED light strip 30 by puncturing. At the same time, they are connected to the base 100 by snap-fitting with the first crimping buckle 200 and the second crimping buckle 300, which can achieve assembly very quickly and very stably.
[0031] 6. Based on the integrated injection molding process, the components are modularly designed. On the one hand, this invention eliminates the need for welding operations, allowing end users to flexibly assemble various connection configurations according to actual needs, such as L-shaped (lamp to lamp, lamp to wire, wire to wire) or T-shaped (lamp to lamp, lamp to wire, wire to wire) configurations. Furthermore, by replacing the cover assembly, the splicing length can be further adjusted, achieving compatibility and expansion for products of different sizes, significantly improving the convenience and reliability of product use. On the other hand, when some components are damaged, users can replace the corresponding modules without discarding the entire terminal block, thereby reducing material waste and promoting resource conservation and sustainable use.
[0032] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
