Description

Technical Field

[0001] This utility model relates to the field of weld-free head technology, specifically to a puncture-type weld-free head. Background Technology

[0002] In the field of modern lighting and decoration, LED flexible light strips have been widely used in diverse scenarios due to their significant advantages such as good flexibility, convenient installation, uniform light emission, and low energy consumption. These applications cover basic lighting needs in places such as office buildings and homes, as well as automotive decorative lighting, signage and advertising sign lighting. They also play an important role in scenarios with high requirements for decorative effects, such as hotels, jewelry stores, and entertainment venues, making them one of the product types with the greatest market potential in the current lighting industry.

[0003] Because different application scenarios have varying requirements for the length of LED flexible light strips, in actual use, it is often necessary to cut the LED flexible light strips according to the specific installation space and lighting needs. For the cut LED flexible light strip to function properly and emit light, it must be effectively connected to an external circuit or other light strip segments through connectors. Against this backdrop, piercing-type solderless connectors, which eliminate the need for soldering tools and achieve conductive connections simply by physically piercing, greatly simplify the installation process and have gradually become a commonly used component for connecting LED flexible light strips.

[0004] However, existing piercing-type solderless connectors on the market generally have significant structural design flaws. Conventional piercing-type solderless connectors typically consist of three parts: a cover, a base, and a mounting plate for fixing the piercing conductive sheet. These three components are designed as separate units (a typical example is the LED flexible light strip solderless plug disclosed in application number CN202221250824.0). This separate structure not only makes the overall connector structure complex, but also requires separate processing and molding of each of the three components during manufacturing, involving cumbersome production processes and hindering production efficiency. Furthermore, the separate design results in a larger number of accessories required for the connector, increasing raw material procurement costs and requiring more manpower and time for subsequent assembly, further increasing the overall production cost. In addition, the numerous accessories and complex structure may also affect the stability and reliability of the connector connection to some extent, causing inconvenience to users.

[0005] Therefore, in response to the problems of complex structure, numerous parts, and high cost of existing piercing-type solderless heads, developing a piercing-type solderless head with a simpler structure, lower cost, and easier operation is of great practical significance for meeting market demand and promoting the development of the LED flexible light strip industry. Utility Model Content

[0006] To address the shortcomings of the prior art, this utility model provides a piercing-type weld-free head.

[0007] The technical solution adopted by this utility model is: a piercing-type solderless head, including a connector housing and a piercing conductive sheet. The connector housing has a receiving cavity with open ends. The piercing conductive sheet is disposed in the receiving cavity. One end of the piercing conductive sheet is provided with piercing protrusions. A pressure cap is flipped and connected to the connector housing on the side of the piercing protrusions.

[0008] Furthermore, the gland is integrally formed with the connector housing via a folding portion, which allows the gland to be flipped relative to the connector housing.

[0009] Furthermore, the connector housing has an extended bottom shell on the side of the piercing protrusion that is adapted to the pressure cap, and the extended bottom shell is provided with a hanging step on both sides, and the pressure cap is provided with elastic hanging rings that cooperate with the hanging step on both sides.

[0010] Furthermore, the piercing conductive sheet includes a wire wrapping ring portion, a limiting portion, and the aforementioned piercing protrusions. The receiving cavity includes a slot for accommodating the piercing protrusions and a main cavity for accommodating the wire wrapping ring portion and the limiting portion. The bottom wall of the main cavity is provided with a clearance bottom groove and a connecting groove in sequence from the opening end toward the slot. The bottom of the limiting portion is provided with an elastic protrusion that connects with the connecting groove.

[0011] Furthermore, the bottom groove is provided with a guide slope on one side of the connecting groove.

[0012] Furthermore, the connector housing, folding portion, and pressure cap are made of plastic material and integrally formed by injection molding.

[0013] The beneficial effects of this utility model are:

[0014] 1. Simple Structure: The connector of this application consists of only two components: a connector housing and a piercing conductive sheet. The piercing conductive sheet is directly integrated into the receiving cavity of the connector housing, eliminating the need for a mounting plate to fix the conductive sheet in traditional structures. Furthermore, a flip-on cap connects to the connector housing, replacing the traditional separate cap design. This integrated structure significantly simplifies the overall construction of the connector, reduces assembly connections between components, fundamentally solves the problem of complex structures in existing products, makes the overall form of the connector simpler, and lays a convenient foundation for subsequent production, assembly, and use.

[0015] 2. Low cost: This application significantly reduces the types and quantities of accessories by simplifying the components to only two. On the one hand, the amount of raw materials purchased is significantly reduced, which can directly reduce raw material costs. On the other hand, the production process is simplified, eliminating the need for separate processing and adaptation of multiple separate components, reducing the number of times production equipment is debugged and the production cycle, and reducing the input of manpower and material resources in the production process. At the same time, in the subsequent assembly stage, the fewer components also reduce assembly time and assembly errors, further reducing the overall production cost and making it more competitive in the market.

[0016] 3. Easy Operation: This application inserts the cut LED flexible light strip under the pressure cover. As the pressure cover presses down, the piercing protrusions of the conductive piercing plate directly contact the conductive part of the light strip. Fixing the light strip and piercing the conductive surface is completed simply by flipping and pressing, without the need for additional complex tools or multi-step component assembly. The entire connection process has few steps and is simple to operate. Whether for professional installers or ordinary users, the operation method can be quickly mastered, effectively improving installation efficiency and reducing the probability of connection failures due to improper operation, significantly enhancing the user experience.

[0017] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0026] This invention provides a piercing-type weld-free head.

[0027] In this embodiment, refer to Figure 1-4 The piercing-type solderless connector includes a connector housing 1 and a piercing conductive sheet 2. The connector housing 1 has a receiving cavity 3, which is open at both ends. The piercing conductive sheet is disposed in the receiving cavity 3. One end of the piercing conductive sheet is provided with a piercing protrusion 4. A pressure cap 5 is flipped and connected to the connector housing located on one side of the piercing protrusion 4.

[0028] In the above technical solution, the receiving cavity of the connector housing is designed to be open at both ends. On the one hand, it provides a channel for the insertion of the LED flexible light strip, ensuring that the light strip can extend smoothly to the location of the piercing conductive sheet; on the other hand, it provides a stable installation space for the piercing conductive sheet, preventing displacement of the conductive sheet during use. Secondly, the piercing protrusions of the piercing conductive sheet, as the core conductive component, have a pointed structure that can penetrate the insulating outer layer of the LED flexible light strip under external pressure, directly contacting the conductive lines inside the light strip to form an electrical connection path. Finally, the flip-connected pressure cap on the connector housing can apply pressure to the LED flexible light strip through its flipping action. On the one hand, it tightly presses the light strip onto the piercing protrusions, ensuring that the protrusions can effectively pierce the insulation layer and maintain close contact with the conductive lines; on the other hand, it forms a fixed constraint on the light strip and the conductive sheet, preventing the connection from loosening due to external pulling or vibration.

[0029] When using it, place the cut light strip under the cover and close the cover to connect the light strip. It is easy to operate. The overall structure consists of a connector shell and a piercing conductive sheet, which has the advantages of fewer accessories, simple structure and low cost.

[0030] Specifically, the pressure cap is integrally formed with the connector housing via a folding portion 6, which allows the pressure cap to be flipped relative to the connector housing.

[0031] In this embodiment, the cap is integrally formed with the connector housing through the folding part, which eliminates the assembly process such as hinge installation and shaft connection required by traditional split caps, reduces the number of parts and assembly steps, lowers labor and time costs in the production process, and improves production efficiency.

[0032] Specifically, the connector housing has an extended bottom shell 7 on the side of the piercing protrusion that is adapted to the pressure cap. The extended bottom shell 7 has a hanging step 8 on both sides, and the pressure cap has elastic hanging rings 9 on both sides that cooperate with the hanging step 8.

[0033] In this embodiment, the elastic hanging ring and the mounting step are connected in a coordinated manner. When the cover is closed, the displacement of the cover can be effectively restricted, ensuring that the cover continuously applies pressure to the LED flexible light strip and the piercing protrusions. This prevents the cover from loosening due to external forces such as vibration and pulling, thereby ensuring tight contact between the piercing protrusions and the conductive circuit of the light strip and preventing poor contact problems.

[0034] Specifically, the piercing conductive sheet includes a wire-wrapping ring portion 10, a limiting portion 11, and the aforementioned piercing protrusion 4. The receiving cavity includes a slot 12 for accommodating the piercing protrusion and a main cavity 13 for accommodating the wire-wrapping ring portion and the limiting portion. The bottom wall of the main cavity 13 is provided with a clearance bottom groove 14 and a connecting groove 15 sequentially from the opening end towards the slot. The bottom of the limiting portion is provided with an elastic protrusion 16 that connects with the connecting groove.

[0035] In this embodiment, the corresponding design of the slot and the piercing protrusion, the main cavity and the wrapping ring and the limiting part ensures that the conductive sheet can be accurately aligned after being installed in the receiving cavity, avoiding the problem of the protrusion being misaligned and unable to contact the conductive line of the lamp strip; the elastic protrusion and the snap-fit ​​of the connecting slot further fix the position of the conductive sheet, preventing the conductive sheet from loosening due to vibration or external force during use, thus improving the overall assembly accuracy.

[0036] During assembly, simply align one end of the piercing conductive sheet with the receiving cavity and insert it firmly to complete the assembly of the two components; assembly is very convenient. The clearance groove provides clearance space for the elastic protrusion, making it easier for the conductive sheet to be inserted into the main cavity without the need for forced pressing or adjustment, reducing assembly difficulty and improving production assembly efficiency.

[0037] Specifically, the bottom groove is provided with a guide slope 17 on one side of the connecting groove.

[0038] In this embodiment, the guide slope avoids direct rigid collision between the elastic protrusion and the edge of the relief groove. The guide slope allows the elastic protrusion to deform smoothly and be easily inserted into the connection groove, which greatly reduces the resistance during the installation of the conductive sheet. No tools or extra force are required, which improves assembly efficiency and ease of operation.

[0039] Specifically, the connector housing, folding part, and pressure cap are made of plastic material and are integrally formed by injection molding.

[0040] In this embodiment, the insulating properties of the plastic material can effectively isolate the puncture-type conductive sheet from the external environment, preventing users from touching conductive parts during operation and causing electric shock risks. At the same time, it prevents external moisture, dust and other conductive media from entering the connector and causing short circuits, thus improving the safety of the connector.

[0041] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
