DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0034] In a lighting device (such as a flashlight), a connecting wire is usually used between the control circuit board and the power supply circuit board to realize electrical conduction between the two. However, the control circuit board and the power supply circuit board must pass through the power supply (such as a battery), and the power supply generates a large amount of heat when it is working normally. This heat directly affects the electrical connection of the connecting wire between the control circuit board and the power supply circuit board, and the replacement operation of the connecting wire is complicated, thereby causing the lighting device to be unable to work effectively and normally. Therefore, how to effectively reduce the operation difficulty of replacing the connecting wire to ensure the effective and normal working of the lighting device has become a problem to be solved.

[0035] In order to solve the above technical problems, please refer to Figures 1-4 The first aspect of the present application proposes a wiring structure 10 which can effectively reduce the operation difficulty of replacing the connecting wire to ensure the effective and normal working of the lighting device 30.

[0036] The wiring structure 10 comprises a first wiring 11, a second wiring 12 and a connecting piece 13. The first wiring 11 comprises a first contact end 111 and a second contact end 112, and the second contact end 112 is configured to be electrically connected with the first circuit board 21. The second wiring 12 comprises a third contact end 121 and a fourth contact end 122, and the fourth contact end 122 is configured to be electrically connected with the second circuit board 22. The connecting piece 13 is arranged outside the first wiring 11, and the relative position between the connecting piece 13 and the first wiring 11 is adjustable. The third contact end 121 is wound around the first contact end 111, and the connecting piece 13 is configured to fix the relative position between the third contact end 121 and the first contact end 111.

[0037] The wiring structure 10 is convenient to replace. The second contact end 112 of the first wiring 11 is configured to be electrically connected with the first circuit board 21. The fourth contact end 122 of the second wiring 12 is configured to be electrically connected with the second circuit board 22. The third contact end 121 of the second wiring 12 is wound around the first contact end 111 of the first wiring 11. The connecting piece 13 is adjustable relative to the first wiring 11 to the winding position of the first contact end 111 of the first wiring 11 and the third contact end 121 of the second wiring 12, and is configured to fix the relative position between the first contact end 111 of the first wiring 11 and the third contact end 121 of the second wiring 12. Thus, the electrical conduction between the first circuit board 21, the first wiring 11, the second wiring 12 and the second circuit board 22 is realized. The connecting piece 13 is designed to facilitate the installation and disassembly of the first wiring 11 and the second wiring 12, so as to replace the damaged first wiring 11 or second wiring 12.

[0038] The specific structure of the wiring structure 10 will be described below. Figures 1-4 The wiring structure 10 comprises a first wiring 11, a second wiring 12 and a connecting piece 13.

[0039] As shown in FIG. 1, the first wiring 11 is one of the components of the wiring structure 10 for realizing the electrical conduction of the circuit. The first wiring 11 comprises a first contact end 111 and a second contact end 112. The conductive core exposed outside after stripping the insulating skin at both ends of the first wiring 11 is the first contact end 111 and the second contact end 112. Figure 1

[0040] ​The second wire 12 is another component in the wire structure 10 for realizing the conduction of the circuit, and the second wire 12 comprises a third contact end 121 and a fourth contact end 122. The conductive core exposed after the two ends of the second wire 12 are stripped of the insulating sheath is the third contact end 121 and the fourth contact end 122. The fourth contact end 122 is used for electrical connection with the second circuit board 22. The fourth contact end 122 of the second wire 12 and the second circuit board 22 can be electrically connected by soldering or through a conductive terminal seat.

[0041] As shown in Figure 2 The connecting piece 13 is a component in the wire structure 10 for connecting the first wire 11 and the second wire 12 in structure. The connecting piece 13 is equivalent to soldering to connect the first wire 11 and the second wire 12 in structure to avoid separation of the first wire 11 and the second wire 12. The connecting piece 13 is arranged in the first wire 11, which means that part of the first wire 11 is arranged in the connecting piece 13. The relative position between the connecting piece 13 and the first wire 11 can be adjusted. For example, the connecting piece 13 can be fixed, and the first wire 11 can move to change the relative position between the connecting piece 13 and the first wire 11. Alternatively, the connecting piece 13 can move, and the first wire 11 can be fixed to change the relative position between the connecting piece 13 and the first wire 11. Alternatively, the connecting piece 13 can move, and the first wire 11 can also move, but the movement direction of the connecting piece 13 and the first wire 11 is opposite, or the movement direction is the same but there is a distance difference, so as to change the relative position between the connecting piece 13 and the first wire 11.

[0042] The third contact end 121 can be wound around the first contact end 111. The conductive core of the second wire 12 away from the second circuit board 22 and the conductive core of the first wire 11 away from the first circuit board 21 can be wound around in a clockwise direction or in a counterclockwise direction to form a conductive core.

[0043] The connecting piece 13 is configured to fix the relative position between the third contact end 121 and the first contact end 111. The connecting piece 13 is adjusted relative to the first wire 11 to the vicinity of the intersection winding point of the third contact end 121 and the first contact end 111, and the third contact end 121 and the first contact end 111 are fixed to avoid disengagement of the third contact end 121 and the first contact end 111, so as to realize stable connection of the first wire 11 and the second wire 12 in structure and good conduction in electrical property.

[0044] As shown in Figures 1-2As shown, there are many specific forms of the connecting member 13 which is a firm connection in structure between the first contact end 111 of the first wire 11 and the third contact end 121 of the second wire 12. In order to facilitate the replacement of the damaged first wire 11 or second wire 12 in the later stage, the connecting member 13 further comprises a main body part 131 and a pressing part 132 in some embodiments. The main body part 131 has a wire hole 13111 for the first wire 11 to pass through. The main body part 131 also has an insertion hole 13112 for the third contact end 121 and the first contact end 111 to be inserted after winding. The hole axis of the insertion hole 13112 is parallel to the hole axis of the wire hole 13111. The pressing part 132 is in sliding connection with the main body part 131 and can rotate relative to the main body part 131. The pressing part 132 is in clamping connection with the main body part 131 when it slides to a preset position, and is in abutment with the third contact end 121 and the first contact end 111 to fix the third contact end 121 and the first contact end 111. That is, after the pressing part 132 slides to the preset position relative to the main body part 131, the pressing part 132 rotates relative to the main body part 131 to be in clamping connection with the main body part 131, so as to realize the relative fixation of the position between the pressing part 132 and the main body part 131. The first contact end 111 of the first wire 11 and the third contact end 121 of the second wire 12 are between the pressing part 132 and the main body part 131, so as to realize the good pressing fixation of the first contact end 111 of the first wire 11 and the third contact end 121 of the second wire 12. After the pressing part 132 slides to other positions relative to the main body part 131, the pressing part 132 rotates relative to the main body part 131 to be separated from the main body part 131, so as to realize the disassembly between the first contact end 111 of the first wire 11 and the third contact end 121 of the second wire 12.

[0045] As Figures 1-2As shown, specifically, in some embodiments, the main body 131 includes a bottom plate 1311 and two side plates 1312, the wire passing hole 13111 and the jack 13112 are located on the bottom plate 1311, the two side plates 1312 are respectively connected to two opposite sides of the bottom plate 1311, and the two side plates 1312 are located on the side where the wire passing hole 13111 is located, the oppositely arranged surfaces of the two side plates 1312 are each provided with a sliding groove 13121 along a preset direction, and the pressing portion 132 is in sliding connection with the sliding groove 13121, and the preset direction is a direction parallel to the hole axis of the wire passing hole 13111. Among them, the two side plates 1312 and the bottom plate 1311 can be formed in an integrated structure by injection molding, the two side plates 1312 and the bottom plate 1311 surround to form a containing space, the wire passing hole 13111 and the jack 13112 are opened on the bottom plate 1311 and located in the containing space, the oppositely arranged surfaces of the two side plates 1312 are inwardly recessed to form the sliding groove 13121 extending along the preset direction, and the preset direction is parallel to the direction of the hole axis of the wire passing hole 13111. In this design, by designing the bottom plate 1311, the bottom plate 1311 is used to open the wire passing hole 13111 for the first wire 11 to pass through to support the first wire 11, and the bottom plate 1311 is used to open the jack 13112 for the first contact end 111 and the third contact end 121 after being crossed and wound to be inserted to fix the first contact end 111 and the third contact end 121; by designing the side plate 1312, the side plate 1312 is provided with the sliding groove 13121 for the pressing portion 132 to be in sliding connection, so as to change the position of the pressing portion 132 to realize the clamping connection between the pressing portion 132 and the main body 131, so as to press the first contact end 111 of the first wire 11 and the third contact end 121 of the second wire 12.

[0046] As Figures 1-2As shown, specifically, in some embodiments, the pressing part 132 includes a pressing plate 1321 abutting against the third contact end 121 and the first contact end 111 at a preset position, and two supporting plates connected to two opposite sides of the pressing plate 1321, respectively, one end of each of the two supporting plates away from the pressing plate 1321 is connected to one of the two sliding grooves 13121 correspondingly and rotatable relative to the sliding groove 13121, and the wiring structure 10 further includes a clamping piece 14 arranged on the supporting plate and the side plate 1312, and the supporting plate is clamped and connected to the side plate 1312 via the clamping piece 14. Wherein, the pressing plate 1321 and the two supporting plates can be formed into an integrated structure by injection molding. In this design, one end of each of the two supporting plates away from the pressing plate 1321 is slidingly matched with the sliding groove 13121 to change the relative position between the pressing part 132 and the main body part 131, the clamping piece 14 is arranged on the supporting plate and the side plate 1312, and the supporting plate is clamped and connected to the side plate 1312 via the clamping piece 14, so as to realize the clamped connection between the pressing part 132 and the main body part 131, thereby pressing the first contact end 111 of the first wiring 11 and the third contact end 121 of the second wiring 12.

[0047] As shown in Figures 3-4 For the sake of realizing the clamped connection between the supporting plate and the side plate 1312, there can be many specific forms of the clamping piece 14, and for the sake of realizing the disassembly and portability between the first wiring 11 and the second wiring 12, further design is made that, in some embodiments, the clamping piece 14 includes a clamping block 141 and a clamping groove 142, the clamping block 141 is arranged on one of the supporting plate and the side plate 1312, the clamping groove 142 is arranged on the other one of the supporting plate and the side plate 1312, and the clamping block 141 is clamped and matched with the clamping groove 142. In this design, the clamped connection between the supporting plate and the side plate 1312 is realized by clamping and matching the clamping block 141 with the clamping groove 142, which is simple, convenient and fast, and greatly improves the portability of the installation and disassembly between the first wiring 11 and the second wiring 12.

[0048] As shown in Figures 3-4As shown, specifically, the surface of the side plate 1312 facing the support plate is provided with a groove 13211, the clamping block 141 comprises a spring 1412 and a clamping block 1411, one end of the spring 1412 is fixedly connected with the clamping block 1411, the other end of the spring 1412 is fixedly connected with the groove bottom wall of the groove 13211, the surface of the side plate 1312 facing the support plate and opposite to the notch of the groove 13211 is provided with the clamping groove 142 when the support plate rotates to the preset position, the clamping groove 142 penetrates the side plate 1312, before the support plate rotates to the preset position, the surface of the side plate 1312 facing the support plate abuts against the clamping block 1411, the clamping block 1411 extrudes the spring 1412 and moves to the groove 13211 in the direction of approaching the groove bottom, when the support plate moves to the preset position and the notch of the groove 13211 is aligned with the notch of the clamping groove 142, the clamping block 1411 moves to the clamping groove 142 in the direction of away from the groove bottom of the groove 13211 under the elastic force of the spring 1412, thereby realizing the relative fixation of the position between the support plate and the side plate 1312, that is, realizing the fixation between the first contact end 111 of the first wire 11 and the third contact end 121 of the second wire 12. When it is needed to disassemble the first wire 11 and the second wire 12, the operator can extrude the clamping block 1411 from the side of the clamping groove 142 away from the notch of the groove 13211 by means of external tools (for example, a thimble), the clamping block 1411 extrudes the spring 1412 and moves in the direction of approaching the groove bottom of the groove 13211 under the force, when the clamping block 1411 moves to be completely accommodated in the groove 13211, the relative movement between the support plate and the side plate 1312 is realized, that is, the position change between the first contact end 111 of the first wire 11 and the third contact end 121 of the second wire 12 is realized.

[0049] As Figures 1-2As shown, considering that the first wire 11 can be formed by a single wire or by multiple parallel wires, in order to enhance the practicability and applicability of the wire structure 10, in some embodiments, the number of the wire passing holes 13111 is multiple, and the multiple wire passing holes 13111 are distributed along the direction perpendicular to the hole axis of the wire passing hole 13111, and / or the number of the insertion holes 13112 is multiple, and the multiple insertion holes 13112 are distributed along the direction perpendicular to the hole axis of the insertion hole 13112. It should be noted that the radial cross-sectional shape of the wire passing hole 13111 is matched with the radial cross-sectional shape of the first wire 11, and the radial cross-sectional area of the wire passing hole 13111 is less than or equal to the radial cross-sectional area of the first wire 11, so that after the first wire 11 is arranged in the wire passing hole 13111, the connection piece 13 cannot easily slide relative to the first wire 11, and the connection piece 13 needs to be moved relative to the first wire 11 under the action of force. In this design, by designing multiple wire passing holes 13111 and / or multiple insertion holes 13112, one connection piece 13 can realize the compression and fixation of the first contact end 111 of the first wire 11 and the third contact end 121 of the second wire 12 after being crossed and wound, thereby enhancing the practicability and applicability of the wire structure 10.

[0050] As shown, Figures 1-2 In order to enhance the connection stability between the first contact end 111 of the first wire 11 and the third contact end 121 of the second wire 12, in some embodiments, the number of the wire passing holes 13111 is multiple, and the number of the insertion holes 13112 is multiple, and the multiple wire passing holes 13111 and the multiple insertion holes 13112 are staggered distributed along the direction perpendicular to the hole axis of the wire passing hole 13111. That is, along the direction perpendicular to the hole axis of the wire passing hole 13111, there is an insertion hole 13112 between any two adjacent wire passing holes 13111. In this design, after the third contact end 121 of the second wire 12 and the first contact end 111 of the first wire 11 are crossed and wound, the third contact end 121 of the second wire 12 and the first contact end 111 of the first wire 11 are bent and wound and inserted into the insertion hole 13112, and after the connection piece 13 compresses and fixes the third contact end 121 of the second wire 12 and the first contact end 111 of the first wire 11, the insertion hole 13112 limits the third contact end 121 of the second wire 12 and the first contact end 111 of the first wire 11, thereby effectively avoiding the disconnection between the third contact end 121 of the second wire 12 and the first contact end 111 of the first wire 11, and enhancing the connection stability between the third contact end 121 of the second wire 12 and the first contact end 111 of the first wire 11.

In this design, by designing the mounting groove 13113 on the main body, the mounting groove 13113 is used for fixing the second wire 12, which enhances the connection stability between the second wire 12 and the connecting piece 13, thereby improving the structural stability of the whole wire structure 10.
