Description

Technical Field

[0001] This utility model belongs to the field of flashlight technology, specifically a multi-conductive structure for a single body of a flashlight. Background Technology

[0002] In existing flashlights, the current is supplied by a battery inside the device, and the conductive material inside the device connects the head and tail of the flashlight through a conductive body.

[0003] Most flashlights currently use a single-body design, where the body can only transmit a single circuit to either the head or the tail, limiting the flashlight to a limited range of functions and reducing its versatility. Some flashlights use a dual-body design, which enables bidirectional circuit transmission and increases versatility. However, dual-body designs increase the size and shape of the flashlight, and the closer proximity of the contact points in dual-body designs leads to a higher failure rate, thus failing to meet the growing needs of users. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-conductive structure for a single body of a flashlight.

[0005] The technical solution adopted by this utility model is as follows: a multi-conductive structure for a single body of a flashlight, including a body, a head, a tail, and a circuit board, wherein the body includes multiple segments cut along its circumferential direction, the segments are made of conductive material, the multiple segments are sequentially fixed together by nano-injection molding technology, a connecting segment is provided between each pair of segments, and the body is separated into multiple conductive areas by the connecting segment.

[0006] In a preferred embodiment, external threads are provided on both outer walls of the cylinder body, and internal threads that are adapted to the external threads are provided at the opposite ends of the cylinder head and cylinder tail.

[0007] In a preferred embodiment, there are two circuit boards, which are respectively installed in the pre-reserved receiving cavities inside the cylinder head and cylinder tail. The side wall of the circuit board has a positioning protrusion, and the receiving cavity is provided with a positioning groove that matches the positioning protrusion.

[0008] In a preferred embodiment, the outer wall of the circuit board is provided with the same number of conductive sheets as the cylindrical section.

[0009] In a preferred embodiment, limiting steps are provided at both ends of the cylinder body, and one of the conductive sheets protrudes upward to form a limiting baffle. When the cylinder body is installed on the cylinder head and / or cylinder tail, the end face of the limiting step abuts against the limiting baffle. At this time, the conductive sheet and the cylinder segment are arranged in a one-to-one correspondence.

[0010] In a preferred embodiment, the conductive sheet is provided with an upwardly curved spring portion that elastically abuts against the cylindrical section.

[0011] In a preferred embodiment, the connecting segment is made entirely of insulating material.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: the tube body is processed to the design requirements, then the tube body is cut open, and finally the cut tube body is reassembled through nano-injection molding. The tube body with high strength through nano-injection molding can also be divided into multiple conductive areas by using the nano-injection molding part. While maintaining the original volume of the flashlight, multiple circuit transmission is realized, which increases the playability of the flashlight and has advantages that current products do not have.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] A multi-conductive structure for a single body of a flashlight, as shown in the reference. Figure 1-4The device includes a cylindrical body 1, a head 2, a tail 3, and a circuit board 4. The cylindrical body 1 comprises multiple cylindrical segments 11 cut along its circumferential direction. Each cylindrical segment 11 is made of conductive material and is sequentially fixed together using nano-injection molding technology. A connecting segment 12 is provided between each pair of cylindrical segments 11, which separates the cylindrical body 1 into multiple conductive areas. The connecting segment 12 is made entirely of insulating material. The cylindrical body 11 is processed to meet design requirements, then cut into multiple cylindrical segments 11. Finally, the cut cylindrical segments 11 are reassembled using nano-injection molding. The nano-injection molded cylindrical body 1 has considerable strength and can also be divided into multiple conductive areas using the nano-injection molding part. This allows for multi-circuit transmission while maintaining the original size of the flashlight, increasing the flashlight's playability (it can be used for tactical flashlights, etc.). Moreover, the circuit design of the above solution is low and the structure is easy to design and implement.

[0020] The connecting section 12 is preferably made of PBT plastic, but other engineering plastics are also acceptable. The cylindrical section 11 can be 2, 4 or other quantities, and no limitation is made here.

[0021] Reference Figure 1 and Figure 3 As shown, external threads 14 are provided on both outer walls of the cylinder body 1, and internal threads that are compatible with external threads 14 are provided at the opposite ends of the cylinder head 2 and cylinder tail 3. The cylinder body 1 can be connected to the cylinder head 2 and cylinder tail 3 by means of threads. An insulating outer cylinder (not shown in the figure) is also sleeved on the outside of the cylinder body 1.

[0022] Reference Figure 2 and Figure 3 As shown, there are two circuit boards 4, which are respectively installed in the reserved receiving cavities inside the cylinder head 2 and cylinder tail 3. The side wall of the circuit board 4 has a positioning protrusion 41, and the receiving cavity is provided with a positioning groove that matches the positioning protrusion 41. Through the cooperation of the positioning protrusion 41 and the positioning groove, the position of the circuit board 4 in the cylinder head 2 and cylinder tail 3 can be limited. The circuit board 4 can be fixed in the cylinder head 2 and cylinder tail 3 by screws, adhesives or other means.

[0023] Reference Figure 1 , Figure 3 and Figure 4As shown, the outer wall of the circuit board 4 is provided with the same number of conductive plates 42 as the cylindrical section 11. Limiting steps 13 are provided at both ends of the cylindrical body 1. One of the conductive plates 42 protrudes upward to form a limiting baffle 421. When the cylindrical body 1 is installed on the cylindrical head 2 and / or the cylindrical tail 3, the end face of the limiting step 13 abuts against the limiting baffle 421. At this time, the conductive plates 42 are arranged one-to-one with the cylindrical section 11. The conductive plates 42 are provided with an upward-curving spring part 422 that elastically abuts against the cylindrical section 11. Through the cooperation of the limiting step 13 and the limiting baffle 421, the installation position of the cylindrical body 1 can be limited, so that each conductive plate 42 can contact each cylindrical section 11 of the cylindrical body 1 one-to-one, so as to ensure the quality of circuit transmission.

[0024] The height of the limiting baffle 421 can be designed to be the same as the height of the limiting step 13 to avoid affecting the screwing in of the external thread 14.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
