Description

Technical Field

[0001] This utility model relates to the field of LED strip technology, and in particular to a tri-proof LED strip. Background Technology

[0002] LED strip lights are flexible light strips with LED chips, also known as flexible neon tubes. Since LED strip lights typically have power cord soldering points spaced 5cm, 10cm, or longer along their length, users can cut them to the required length according to multiples of the distance between adjacent soldering points. Currently, LED strip lights have a wide range of applications; besides interior decoration, they are also used for aesthetic purposes, even in outdoor decorations.

[0003] Because outdoor lighting is frequently exposed to sun and rain, a plastic sealing layer is usually added to the outside of the light strip to improve its waterproof, dustproof, and corrosion-resistant properties, in order to extend its lifespan and reduce the occurrence of safety accidents such as short circuits. In practical use, there are often needs to splice two light strips when a single strip is not long enough. Currently, there are generally two methods for connecting two light strips:

[0004] One method is to solder the pins on both sides of the light strip together and then wrap tape around the outside. However, this method is simple and crude, and the light strip does not meet the requirements for protection against fire and mud, so it can only be used in emergency situations.

[0005] The second option is to use the manufacturer's provided connectors for connection. However, these existing connectors can only provide initial protection and positioning, and cannot withstand certain axial tensile forces. Moreover, for the three-proof requirements, it is necessary to inject glue into the gap between the connector and the light strip to seal it, so as to achieve a standard connection. However, users need to provide their own glue for this method, which is quite troublesome in actual use.

[0006] It is evident that the light strip described in the second method above still has certain shortcomings. Therefore, it is necessary to propose a more advanced tri-proof light strip. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of the existing technology by providing a tri-proof light strip that can effectively solve the above-mentioned problems.

[0008] To achieve the above requirements, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0009] A tri-proof light strip is provided, comprising a light strip body and a connecting tube head connecting two light strip bodies. The connecting tube head has an elastic partition inside that divides its internal cavity into two independent installation chambers. The elastic partition has an adhesive storage chamber. A conductive terminal is axially inserted through the lower part of the elastic partition corresponding to the connecting terminal of the light strip body. A connecting pin shaft is axially inserted through the elastic partition. Two guide groove groups are axially provided on the side wall of the connecting pin shaft. The length of the guide groove groups is greater than the wall thickness of the adhesive storage chamber. In the initial state, both guide groove groups are located on the same side of the adhesive storage chamber.

[0010] The tri-proof light strip of this utility model, wherein the elastic partition and the connecting tube head are integrally injection molded, and the connecting pin shaft is made of metal and is connected to the partition through an integral insert injection molding process.

[0011] The tri-proof light strip of this utility model has tapered portions at both ends of the connecting pin shaft, and the taper of one of the tapered portions is greater than that of the other.

[0012] The tri-proof light strip of this utility model has an annular groove coaxially provided on the outer wall of the connecting tube head, and the annular groove is provided in multiple ways and distributed axially.

[0013] In the tri-proof light strip of this utility model, two of the plurality of annular grooves are respectively located on the outer sides of the two end walls of the glue storage cavity.

[0014] The tri-proof light strip of this utility model has two connecting pin shafts that are opposite each other, and both connecting pin shafts are located above the conductive terminal.

[0015] The tri-proof light strip of this utility model has a longitudinally arranged rib on the side wall of the elastic partition away from the glue storage cavity, and the rib is located between the connecting terminals of the left and right positive and negative poles of the light strip body.

[0016] The three-proof light strip of this utility model has barbs at both ends of the connecting needle shaft that face each other to prevent detachment.

[0017] The tri-proof light strip of this utility model has a guide groove at the end of the conductive terminal. The guide groove is V-shaped and its two inclined surfaces are arranged vertically. When assembled, the guide groove is clamped on the upper and lower sides of the connecting terminal of the light strip body.

[0018] The tri-proof light strip of this utility model has adhesive on the peripheral wall of the installation chamber.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model has a simple overall structure and is easy and quick to install. Through the double connection of the connecting pin shaft and the connecting tube head, the connection between the two light strips is more secure and more stable. Compared with the traditional connection method that only uses a sleeve, it can withstand a greater axial tensile force and effectively ensure the normal use of the light strips.

[0021] Furthermore, during the insertion of the two light strips into the two mounting chambers, one light strip can be pushed first to move the connecting pin shaft towards the other light strip for insertion. As the connecting pin shaft inserts into the other light strip and moves relative to the elastic partition, the guide channel assembly enters the glue storage chamber from the outside and connects the glue storage chamber with the two mounting chambers. The squeezing force of the inserted light strip causes the partition to deform inward, thereby squeezing the glue out of the glue storage chamber and sealing and filling the gap between the elastic partition and the end of the light strip to prevent external dust and rainwater from entering. After reaching the correct position, the conductive terminal contacts the connecting terminal of the light strip to achieve electrical connection between the two light strips, thereby effectively improving the three-protection effect and ensuring the product's adaptability and service life.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] The preferred embodiment of this utility model is a tri-proof light strip, such as... Figure 1-7 As shown, the tri-proof light strip includes a light strip body 10, the cross-section of which is semi-circular, a mature design in the market. Specifically, the light strip body 10 consists of a flexible substrate 101, a copper-plated circuit layer on the upper surface of the flexible substrate 101, LED beads 102, and a transparent silicone protective layer 103. The LED beads 102 are integrated on the circuit on the upper surface of the flexible substrate 101 and the entire structure is covered inside by the transparent silicone protective layer 103. There is adhesive on the bottom of the transparent silicone protective layer 103 to facilitate sticking the light strip to a wall or other object.

[0036] Furthermore, the tri-proof light strip also includes a connecting tube head 20 connecting the two light strip bodies 10. The cross-section of the connecting tube head 20 is a semi-circle adapted to the light strip body 10. The interior of the connecting tube head 20 has an elastic partition 30 that divides its inner cavity into two independent mounting chambers 40. The cross-sectional size and shape of the mounting chambers 40 are adapted to the light strip body 10. In practice, the inner diameter of the mounting chambers 40 needs to be 1-2 mm smaller than the outer diameter of the light strip body 10 so that a tight assembly relationship with interference fit is formed after assembly, so as to make full use of the elasticity of the transparent silicone protective layer 103 on the outside of the light strip body 10 to promote the sealing effect.

[0037] Furthermore, the elastic partition 30 is provided with an adhesive storage cavity 50. Specifically, the wall thickness of the adhesive storage cavity 50 is at least less than half of its own thickness. Furthermore, conductive terminals 60 are axially provided through the lower part of the elastic partition 30 corresponding to the connecting terminals 1a on the left and right sides of the light strip body 10 (the flexible substrate 101 has connecting terminals 1a on both sides of the cut-out position). When the two light strip bodies 10 are inserted to a certain extent, the connecting terminals 1a of the two light strip bodies 10 can be contacted and connected and pressed together through the conductive terminals 60, thereby realizing a quick electrical connection. Furthermore, a connecting pin shaft 70 is axially provided through the elastic partition 30, so that after the two light strip bodies are inserted into the installation chamber 40, the connecting pin shaft 70 can be inserted into the transparent silicone protective layer 103 to achieve a strong connection. Furthermore, two guide groove groups 80 are axially provided on the side wall of the connecting pin shaft 70. The guide groove group 80 specifically includes multiple axially arranged guide groove bodies 81, which are evenly distributed circumferentially on the connecting pin shaft 70.

[0038] Furthermore, the axial length of the guide channel group 80 is greater than the wall thickness of the glue storage cavity 50; in the initial state, both guide channel groups 80 are located on the same side of the glue storage cavity 50. This design allows the guide channel group 80 to connect the glue storage cavity 50 and the mounting cavity 40 through when the light strip body is inserted and the connecting needle shaft 70 is pushed to move axially, so that the glue can flow out to fill the mounting cavity 40.

[0039] The tri-proof LED strip in this embodiment has a simple overall structure and is easy and quick to install. The double connection between the connecting pin shaft 70 and the connecting tube head 20 makes the connection between the two LED strips more secure and stable. Compared to the traditional connection method that only uses a sleeve, it can withstand greater axial tensile force, effectively ensuring the normal use of the LED strip. Furthermore, when the two LED strips are inserted into the two mounting chambers 40, one LED strip can be pushed first to move the connecting pin shaft 70 towards the other LED strip for insertion. After the connecting pin shaft 70 is inserted into the other LED strip and connects with the elastic partition 30... During relative movement, the guide channel assembly 80 enters the glue storage cavity 50 from the outside and connects the glue storage cavity 50 with the two installation chambers 40. The squeezing force of the inserted light strip causes the partition to deform inward, thereby squeezing the glue out of the glue storage cavity 50 and into the gap between the elastic partition 30 and the end of the light strip for sealing and filling, preventing external dust and rainwater from entering. After it is in place, the conductive terminal 60 contacts the connection terminal 1a of the light strip to realize the electrical connection between the two light strips, thereby effectively improving the three-protection effect and ensuring the adaptability and service life of the product.

[0040] In this embodiment, the elastic partition 30 and the connecting tube head 20 are integrally injection molded. The connecting pin shaft 70 is a smooth metal pin shaft (generally stainless steel) and is connected to the partition through an integral insert injection molding process. This method facilitates the connection of the light strip body 10 later by using the reaction force of the light strip body 10 to push the connecting pin shaft 70 to the other side. In actual installation, one light strip body 10 needs to be inserted first, and then the other light strip body 10 needs to be inserted. Alternatively, both light strip bodies 10 can be inserted into the connecting tube head 20 at the same time, and then one light strip body 10 can be pushed towards the other light strip body 10. This allows the connecting pin shaft 70 to move relative to the elastic partition 30 while being inserted into the transparent silicone protective layer 103, and allows the guide channel group 80 to connect the glue storage cavity 50 and the installation cavity 40.

[0041] In this embodiment, both ends of the connecting pin shaft 70 have tapered portions 71, with the taper of one portion 71 being greater than that of the other. This ensures that the insertion resistance between the connecting pin shaft 70 and the two LED strip bodies 10 is inconsistent, allowing relative movement with the elastic partition 30. This prevents the user from simultaneously inserting the two LED strip bodies 10 into the connecting tube head 20 with the same force during connection, which would result in insufficient relative displacement between the connecting pin shaft 70 and the elastic partition 30 to move the guide channel group 80 into place and achieve the purpose of connecting the glue storage chamber 50 and the installation chamber 40. This ensures that even if the user forgets the normal installation steps, the internal sealant can still flow out and fill the gaps for sealing.

[0042] In this embodiment, an annular groove 21 is coaxially provided on the outer wall of the connecting pipe head. Multiple annular grooves 21 are provided and axially distributed. Among them, two of the multiple annular grooves 21 are respectively provided on the outer side of the two end walls of the glue storage cavity 50. The structural design of the annular groove 21 not only plays a role in preventing slippage and facilitating user operation, but also reduces the deformation resistance on the outer side of the elastic partition 30, thereby increasing the ease of deformation of the elastic partition 30 and ensuring that the opposing deformation and compression of the two elastic partitions 30 are sufficient to squeeze the glue inside into the installation cavity 40.

[0043] In this embodiment, there are two connecting pin shafts 70, which are opposite each other. Both connecting pin shafts 70 are located above the conductive terminal 60 and at the middle height of the elastic partition 30. This position is the position where the elastic partition 30 is most easily deformed, so as to reduce the squeezing force required to squeeze the glue. At the same time, it can avoid the connecting terminal 1a and the lamp bead 102, and ensure that it is inserted into the center of the transparent silicone protective layer 103.

[0044] In this embodiment, the elastic partition 30 has a longitudinally arranged rib 90 on the side wall opposite to the glue storage cavity 50. The rib 90 is located between the left and right positive and negative connection terminals 1a of the light strip body 10, so as to separate the connection terminals 1a on the left and right sides when the light strip body is inserted into place. Furthermore, in order to ensure complete separation, the end of the rib 90 is tapered to be embedded in the light strip body.

[0045] In this embodiment, both ends of the connecting needle shaft 70 have anti-detachment barbs 72 facing each other. The anti-detachment barbs 72 are generally designed in the shape of triangles to further strengthen the connection between the two light strip bodies.

[0046] In this embodiment, the end of the conductive terminal 60 has a guide groove 61. The guide groove 61 is V-shaped and its two inclined surfaces are arranged vertically. When assembled, the guide groove 61 is clamped on the upper and lower sides of the connecting terminal 1a of the light strip body 10 to achieve a tight fit, so as to ensure the stability of conductivity.

[0047] In this embodiment, adhesive is provided on the peripheral sidewall of the mounting chamber 40 to further increase the firmness and sealing of the connection between the connecting tube head 20 and the light strip body.

[0048] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
