Description

TECHNICAL FIELD

[0001] The utility model relates to neon lighting technical field, especially a neon lamp strip welding -free connecting device and neon lamp strip. BACKGROUND

[0002] In the current neon lamp application field, the conventional wiring technology generally adopts the fixed wiring scheme that is pre-welded and sealed by the manufacturer. Specifically, the production end usually fixes the wires and the neon lamp strip by high-temperature soldering, and then uses a customized mold to integrally injection mold or seal the connection, forming an integrated waterproof plug structure, and finally delivers the packaged finished product directly to the customer for use. However, this technical solution has significant defects in actual application and maintenance:

[0003] 1. Since the wiring and sealing links are completely pre-located at the production end, users cannot independently cut, extend or rewire the neon lamp according to the on-site requirements. If the length of the lamp strip needs to be adjusted or the interface position needs to be replaced during construction, the traditional scheme lacks operability, forcing customers to passively accept the fixed design, which seriously restricts the installation adaptability.

[0004] 2. The existing technology completely solidifies the welding point of the wire and the lamp strip inside the sealing plug. Once the local line is damaged or the interface fails, the user cannot perform targeted maintenance and can only replace the entire neon lamp strip. This not only increases maintenance costs but also leads to the redundant scrap of a large number of undamaged components, which is contrary to the current green and sustainable concept.

[0005] 3. Although the sealing process of the production end relies on mold forming can achieve initial waterproofing, in the scenario of user self-wiring, there is a lack of standardized and simplified waterproof structure design support. Conventional soldering with a soldering iron easily damages the original sealing layer, while temporarily added waterproof tape or glue has the problems of low reliability and short service life, making it difficult to meet the long-term stable operation requirements in outdoor or humid environments.

[0037] Please refer to Figures 1-3 The embodiment provides a neon lamp strip welding-free connecting device, which comprises a neon lamp 1, a terminal 2 and a plug 3. The terminal 2 is detachably installed on the neon lamp 1. The plug 3 is sleeved on the neon lamp 1 and the terminal 2 at two ends to form a sealed space at the connection between the terminal 2 and the neon lamp 1. An opening 4 is arranged on the plug 3 and communicates with the sealed space.

[0038] In the embodiment, the neon lamp 1, the terminal 2 and the plug 3 are arranged, and the two ends of the plug 3 are sleeved on the neon lamp 1 and the terminal 2 to form a sealed space at the connection between the terminal 2 and the neon lamp 1. Therefore, the sealant can be injected into the sealed space and solidified, so that the assembly of the neon lamp strip can be completed, welding between the neon lamp strips is avoided, the use of the user is facilitated, the installation adaptability and waterproofness are improved, and the maintenance cost is reduced.

[0039] In the embodiment, the plug 3 comprises a sealing segment 31 and a connecting segment 32 fixedly connected to one end of the sealing segment 31. The other end of the sealing segment 31 is sleeved on the neon lamp 1. One end of the terminal 2 is located in the sealing segment 31. The connecting segment 32 is sleeved on the other end of the terminal 2. The opening 4 is arranged on the sealing segment 31.

[0040] The shape of the sealing section 31 is a tubular structure that fits the shape of the neon 1, and the inner wall closely fits the outer surface of the neon 1 (an interference fit design can be used). The other end of the sealing section 31 is sleeved on the end of the neon 1, and physical wrapping is achieved through elastic deformation of the silicone material, forming a first waterproof barrier. The middle of the sealing section 31 is provided with a glue inlet (i.e. opening 4) for injecting sealing glue (such as epoxy resin or silicone), and after the glue is injected, the glue fills the gap between the sealing section 31 and the neon 1, and after curing, a second waterproof seal is formed. The connecting section 32 is fixedly connected to one end of the sealing section 31 and has the same material as the sealing section 31. The inner diameter of the connecting section 32 is slightly smaller than the outer diameter of the solderless terminal 2, and the terminal 2 is wrapped and fixed through the elastic deformation of the silicone material, forming a third waterproof barrier.

[0041] In this embodiment, when the sealing section 31 is sleeved on the end of the neon 1, it closely fits the outer wall of the neon 1 through the elastic deformation of the silicone material, effectively preventing water from seeping from the contact surface between the neon 1 and the plug 3. At the same time, by sleeving the connecting section 32 on the other end of the terminal 2, the outer wall of the neon 1 is closely fitted through the elastic deformation of the silicone material, effectively preventing water from seeping from the contact surface between the terminal 2 and the plug 3. In addition, the glue injection port is located on the side of the sealing section 31, and after the glue is injected, the glue flows uniformly along the inner wall of the sealing section 31, covering the contact area between the terminal 2 and the neon 1, further improving the sealing and insulation.

[0042] In this embodiment, at least one flow guide groove 21 (as shown in Figure 4 ) is provided on the terminal 2 to communicate with the sealed space.

[0043] The flow guide groove 21 is a longitudinal groove uniformly distributed on the outer circumferential surface of the terminal 2. The cross section of the flow guide groove 21 is U-shaped or trapezoidal to reduce stress concentration and ensure smooth flow of the glue solution. The number of flow guide grooves 21 is adjusted according to the diameter of the terminal 2, for example, one groove is provided when the diameter is ≤10 mm, and 2-4 grooves are symmetrically provided when the diameter is >10 mm.

[0044] When injecting glue, the glue solution is injected through the opening 4 in the side wall of the sealing section 31. The flow guide groove 21 and the opening 4 form a continuous flow channel, and the glue solution quickly spreads to the gap between the terminal 2 and the neon 1 along the flow guide groove 21 and uniformly fills the sealing section 31.

[0045] Through the directional guiding effect of the flow guide groove 21, the glue solution can efficiently fill the gap between the terminal 2 and the neon 1, and at the same time, the generated bubbles can be eliminated, significantly improving the waterproof sealing performance and mechanical fixing strength.

[0046] In this embodiment, please refer to Figure 2 , which further comprises an inner plug 5, one end of the inner plug 5 is mounted on the terminal 2, and the other end of the inner plug 5 is mounted in the neon 1 so that the copper needle 22 (as shown in Figure 4 ) of the terminal 2 abuts against the lamp panel of the neon 1.

[0047] Since the neon 1 is internally hollow, after the terminal 2 is inserted, the lamp plate of the neon 1 will be squeezed to the hollow side, thereby affecting the contact conduction of the copper needle 22 of the terminal 2 and the lamp plate of the neon 1. The inner plug 5 can fill the cavity, thereby ensuring the close contact of the copper needle 22 of the terminal 2 and the lamp plate of the neon 1, and thereby avoiding the breakage of the contact between the copper needle 22 of the terminal 2 and the lamp plate of the neon 1.

[0048] In the embodiment, referring to Figure 5 , the inner plug 5 comprises a mounting section 51 and a filling section 52 fixedly connected with the mounting section 51, the mounting section 51 is mounted on the terminal 2, and the filling section 52 is mounted in the neon 1.

[0049] Specifically, the filling section 52 is in a conical or wedge-shaped structure, and the outer diameter is slightly larger than the inner diameter of the internal cavity of the neon 1. After being pressed into the cavity by elastic deformation, the filling section 52 is tightly attached to the inner wall of the neon 1 by the material resilience. The surface of the filling section 52 can be provided with anti-skid lines or protruding strips to increase the friction with the inner wall of the neon 1, thereby preventing the inner plug 5 from loosening.

[0050] The inner plug 5 and the terminal 2 can be provided in a split body manner (as shown in Figure 2 ), and specifically, the mounting section 51 is provided with a mounting hole 53, and the inner plug 5 passes through the mounting hole 53 of the copper needle 22 of the terminal 2 to be mounted on the terminal 2.

[0051] The split body design of the inner plug 5 and the terminal 2 makes the inner plug 5 flexible to replace according to actual needs. In different application scenarios or product designs, the material, size, performance, etc. of the inner plug 5 may need to be adjusted. This split body design can conveniently realize the replacement of the inner plug 5 without the need to redesign or replace the entire terminal 2, greatly improving the universality and adaptability of the product.

[0052] In some embodiments, the inner plug 5 and the terminal 2 can also be provided in an integrated manner (as shown in Figure 6 ), and the integrated design makes the inner plug 5 and the terminal 2 become an indivisible whole, avoiding the problems of loose connection and falling off that may occur in the split body structure. In the process of bearing external force or long-term use, the integrated structure can better maintain the stability of its shape and position.

[0053] In the embodiment, the mounting section 51 is provided in a stepped shape.

[0054] The stepped design makes the inner plug 5 have a groove between the inner plug 5 and the neon 1 after the filling section 52 fills the internal cavity of the neon 1. Thus, after the glue solution is injected into the sealed space, the glue solution can quickly spread to the gap between the terminal 2 and the neon 1 along the groove and uniformly fill into the sealing section 31.

[0055] Through the directional guiding effect of the groove, the glue solution can efficiently fill the gap between the terminal 2 and the neon 1, and can eliminate the generated bubbles, significantly improving the waterproof sealing performance and mechanical fixing strength.

[0056] In this embodiment, the end of the filling section 52 away from the terminal 2 is provided with a bevel or an arc.

[0057] When it is necessary to insert the filling section 52 into the internal cavity of the neon 1, the bevel or the arc can play a guiding role. Compared with a right angle end, the bevel or the arc can more smoothly guide the component to enter, reduce the resistance and interference during insertion, reduce the assembly difficulty, and improve the assembly efficiency. At the same time, during the assembly process, if the end of the filling section 52 is a right angle, burrs, deformation or even damage may be caused by collision and friction with the neon 1 during insertion. The bevel or the arc arrangement can make the contact process more gentle, disperse the stress, reduce damage caused by excessive local pressure, thereby prolonging the service life of the component and reducing the maintenance and replacement cost caused by assembly damage.

[0058] In this embodiment, the filling section 52 is composed of two side plates 521 and one bottom plate 522, and forms a U-shaped structure, and the end of the two opposite side plates 521 close to the mounting section 51 is provided with a deformation groove 523.

[0059] The deformation groove 523 allows the side plate 521 to bend inwardly to the U-shaped opening 4 when pressed, enhancing the elastic fit to the inner wall of the neon 1.

[0060] In this embodiment, please refer to Figure 2 It also includes a protective shell 6, which is sleeved on the plug 3.

[0061] The protective shell 6 can provide an additional protection for the plug 3 and the neon 1. Even if a slight collision or friction occurs, the protective shell 6 can first bear the impact force, reducing the damage to the plug 3 and the neon 1 itself, thereby prolonging the service life of the plug 3 and the neon 1.

[0062] Further, the two ends of the protective shell 6 are provided with through holes 61 (as Figure 7 shown), and the shapes and sizes of the two through holes 61 are the same.

[0063] The two end through holes 61 of the protective shell 6 are symmetrically designed, and no direction needs to be distinguished during installation, supporting bidirectional assembly, improving the convenience and efficiency of assembly. At the same time, the shapes and sizes of the two end through holes 61 are consistent, reducing the complexity of the mold and the production cost, and improving the interchangeability of the parts.

[0064] In this embodiment, the installation process of the neon lamp strip welding-free connecting device is as follows:

[0065] 1) First, install the inner plug 5 on the terminal 2;

[0066] 2) Reinsert the copper pin 22 of the terminal 2 into the neon 1, so that the copper pin 22 on the terminal 2 and the lamp plate in the neon 1 are in contact to realize conduction;

[0067] 3) Then, the plug 3 is sleeved on the neon 1;

[0068] 4) Then, glue injection is performed from the opening 4;

[0069] 5) Then, the protective shell 6 is pushed to cover the plug 3, so as to complete the installation.

[0070] The embodiment also provides a neon lamp strip, which comprises the neon lamp strip welding-free connecting device.
