Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a tensile-resistant wire harness and a lighting fixture equipped with the tensile-resistant wire harness. Background Technology

[0002] Lighting fixtures require wiring harnesses to connect to an external power source or power supply system to power the light source module. To ensure the reliability, safety, and stability of the power supply, the wiring harnesses are typically subjected to tensile strength treatment; for example, ... Figure 1 As shown, the wire harness 93 is fixed to the lamp body 94 by the cooperation of the wire clamp 91 and the screw 92. This method can improve the tensile strength of the wire harness 93 to a certain extent, but the effect is limited; for example, as Figure 2 As shown, a wire fixing structure 951 is formed on the wire harness 95. The wire fixing structure 951 is initially engaged and positioned with the lamp body through its slot 9511. Then, screws are used to fix the wire fixing structure 951 to the lamp body to prevent the wire fixing structure 951 from detaching from the lamp body and to ensure the tensile strength of the wire harness 95. For example, as... Figure 3 As shown, by setting a sheath lock 96 on the wire harness and using a nut 97 to cooperate with the sheath lock 96, the wire harness is fixed to the lamp body 98, thereby ensuring the tensile strength of the wire harness.

[0003] However, all of the above-mentioned tensile treatments for wire harnesses have the following shortcomings: First, structural components also require drilling, which increases processing costs. Second, the large number of parts required for assembly leads to low assembly efficiency and increases production costs. Summary of the Invention

[0004] To address the aforementioned problems, the primary objective of this invention is to provide a tensile-resistant wire harness that is easy to assemble and has low cost.

[0005] The second objective of this invention is to provide a lamp with the aforementioned tensile wire harness.

[0006] To achieve the primary objective of this utility model, it provides a tensile-resistant wire harness, comprising a core and a sheath, with the sheath wrapping around the core. An integrally formed connecting portion is provided on the sheath, the connecting portion having an elastic locking arm and a limiting baffle. The elastic locking arm extends obliquely from the sheath away from it and obliquely toward the limiting baffle. The elastic locking arm has an open position and a retracted position. When the elastic locking arm is in the open position, a locking mechanism is formed between the extended end of the elastic locking arm and the limiting baffle.

[0007] As can be seen above, when the connector is connected to the socket of the lamp body, as the connector is inserted into the socket, the extended end of the elastic locking arm is pressed and moves elastically towards the wire sheath to the retracted position. When the elastic locking arm passes through the socket and enters the lamp body as the connector is inserted, the elastic locking arm returns to the open position and the limiting baffle is located outside the socket. At this time, the locking position formed by the extended end of the elastic locking arm and the limiting baffle engages with the surrounding structure of the socket, thereby restricting the axial movement of the connector along the socket and preventing the connector from separating from the socket, thus achieving the tensile strength effect of the tensile wire harness. Through the design of the connector, the assembly of the tensile wire harness and the lamp body is more convenient and faster, and no additional parts are required during assembly, improving assembly efficiency and reducing production costs.

[0008] A preferred embodiment is that the extended end of the elastic locking arm has a stepped portion between it and the limiting baffle; along the height direction of the stepped portion, when the elastic locking arm is in the open position, the projection of the extended end of the elastic locking arm is outside the projection of the stepped portion, and when the elastic locking arm is in the retracted position, the projection of the elastic locking arm is inside the projection of the stepped portion, and the projection of the stepped portion is inside the projection of the limiting baffle.

[0009] As can be seen from the above, the design of the stepped part and its elastic locking arm in different positions can ensure that the elastic locking arm passes through the socket and enters the lamp body during the assembly process. After the assembly is completed, the stepped part can also fit tightly with the peripheral wall of the socket to prevent the connecting part and the tensile wire harness from moving radially in the socket. At the same time, it can also help the limiting baffle to better cover the socket and prevent external parts from entering the lamp body, affecting the lighting effect and causing a short circuit in the circuit system.

[0010] Another preferred embodiment is that the core includes a neutral wire, a live wire, and a ground wire, with the ground wire electrically connected to the wire lug at the end near the flexible arm.

[0011] As can be seen from the above, the installation of a ground wire can improve the safety of use. At the same time, the ground wire lugs also ensure the firmness and convenience of the connection between the lamp body and the ground wire, ensuring the reliability of the lamp grounding.

[0012] Another preferred embodiment is that the wire sheath is integrally formed with a wiring structure, and the limiting baffle is located between the elastic clamping arm and the wiring structure; the wiring structure is a wire fixing part with a slot on the wire fixing part, or the wiring structure is a plug.

[0013] As can be seen from the above, the wiring structure makes it easier to connect the tensile wire harness to other components.

[0014] Another preferred embodiment is that one end of the tensile wire harness is provided with a power module, which is electrically connected to the core, and the limiting baffle is located between the elastic clamping arm and the power module.

[0015] As can be seen from the above, when a power module cannot be installed inside the luminaire, a power module can be installed on the tensile wire harness to improve the convenience of luminaire installation and use.

[0016] A further option is to have two to four elastic clamping arms, which are distributed circumferentially along the skin.

[0017] As can be seen from the above, the design of the number of flexible clamps ensures a firm connection between the tensile wire harness and the lamp body, providing excellent tensile strength. On the other hand, it simplifies the structure of the tensile wire harness and makes it easier to disassemble and reassemble the tensile wire harness from the lamp body.

[0018] A further solution is to provide a limiting part on the limiting baffle; the limiting part is a notch, which is recessed from the limiting surface of the limiting baffle facing the elastic clamping arm and away from the elastic clamping arm, or the limiting part is a protrusion, which protrudes from the limiting surface facing the elastic clamping arm, or the protrusion protrudes from the peripheral wall of the limiting baffle towards the outside of the limiting baffle.

[0019] As can be seen from the above, this design allows the tensile wire harness to engage with the second limiting part on the lamp body after it is installed on the lamp body, so as to prevent the tensile wire harness from rotating relative to the socket, thereby avoiding the core from being twisted and protecting the tensile wire harness.

[0020] To achieve the second objective of this utility model, this utility model provides a lamp, including a lamp body and a light source module. The lamp body is provided with a socket, and the light source module is installed in the lamp body. The lamp also includes the aforementioned tensile wire harness, the connecting part is connected to the socket, the elastic locking arm is located inside the socket, the limiting baffle is located outside the socket, and the core is electrically connected to the light source module.

[0021] As can be seen from the above, by incorporating the aforementioned tensile wire harness, the assembly of the lamp body and the tensile wire harness during the production process becomes more convenient and faster, with fewer assembly steps and required parts, thereby improving production efficiency and reducing production costs.

[0022] A further solution is to have a notch in one of the limiting baffles and a protrusion in the other, with the protrusion inserted into the notch.

[0023] As can be seen from the above, this design can prevent the tension harness from rotating relative to the socket after it is installed on the lamp body, thereby avoiding the core from being twisted and protecting the tension harness.

[0024] A further improvement is that the lamp body has a countersunk hole on the inside of the socket, the countersunk hole is connected to the socket, and the protruding end of the elastic locking arm is located inside the countersunk hole.

[0025] As can be seen from the above, the countersunk hole design can effectively prevent the protruding end of the tensile wire harness from being accidentally pushed and causing the connection part to detach from the socket during the assembly of the lamp. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0039] Lighting Fixture Examples Reference Figure 4 and Figure 5 The lamp 100 includes a tensile wire harness 1, a lamp body 2, and a light source module. The light source module is installed inside the lamp body 2 and is electrically connected to the tensile wire harness 1, so that the tensile wire harness 1 can supply power to the light source module.

[0040] Reference Figure 6The tensile-resistant wire harness 1 includes a core 11 and a sheath 12. The core 11 preferably includes a neutral wire 111, a live wire 112, and a ground wire 113. The neutral wire 111 and live wire 112 are electrically connected to the light source module, and the ground wire 113 is electrically connected to the lamp body 2 or the light source module. Preferably, the end of the ground wire 113 extending into the lamp body 2 is provided with a lug 1131 (i.e., the end of the ground wire 113 near the elastic clip arm 1211 described below). The lug 1131 is electrically connected to the ground wire 113, and the lug 1131 has a connecting through hole, allowing the lug 1131 to be connected to the lamp body 2 or the light source module via a screw. This ensures the secure and convenient connection of the ground wire 113 to the lamp body 2 or the light source module, and ensures the reliability of the grounding of the lamp 100. The ground wire 113 improves the safety of the lamp 100. Of course, in some embodiments, the core 11 may not include the ground wire 113.

[0041] The sheath 12 is wrapped around the core 11 to protect it and provide insulation, ensuring the safe use of the tensile harness 1. The sheath 12 has a connecting portion 121 at its first end, which is preferably integrally injection molded with the sheath 12. The connecting portion 121 has an elastic retaining arm 1211, a limiting baffle 1212, and a stepped portion 1213.

[0042] The elastic locking arm 1211 extends from the wire sheath 12, and the elastic locking arm 1211 is inclined away from the wire sheath 12 and inclined towards the limiting baffle 1212, so that the elastic locking arm 1211 has a structure similar to an inverted buckle; wherein, the elastic locking arm 1211 has an open position (the normal position state when the elastic locking arm 1211 is not under force, which is visible) Figure 5 , Figure 6 and Figure 9 The position of the elastic locking arm 1211 is as follows: when the elastic locking arm 1211 is in the open position, the extended end of the elastic locking arm 1211 forms a locking position 120 with the limiting baffle 1212. The locking position 120 is used to cooperate with the lamp body 2 to achieve the tensile effect of the tensile wire harness 1, thereby preventing the assembled tensile wire harness 1 from detaching from the lamp body 2.

[0043] The stepped portion 1213 is located between the extended end of the elastic locking arm 1211 and the limiting baffle 1212. Along the height direction of the stepped portion 1213, the projection of the stepped portion 1213 is located within the projection of the limiting baffle 1212. Furthermore, when the elastic locking arm 1211 is in the open position, along the height direction of the stepped portion 1213, the projection of the extended end of the elastic locking arm 1211 is located outside the projection of the stepped portion 1213; when the elastic locking arm 1211 is in the retracted position, along the height direction of the stepped portion 1213, the projection of the stepped portion 1213 is located within the projection of the limiting baffle 1212. The design of the stepped portion 1213 and the elastic locking arm 1211 in different positions ensures that the elastic locking arm 1211 passes through the socket 21 of the lamp body 2 and enters the interior of the lamp body 2 during the assembly process. Furthermore, after the connecting portion 121 is assembled with the lamp body 2, the stepped portion 1213 can fit more tightly with the peripheral wall of the socket 21 to prevent the connecting portion 121 and the tensile wire harness 1 from moving radially in the socket 21. At the same time, it also helps the limiting baffle 1212 to better cover the socket 21, preventing external parts from entering the interior of the lamp body 2, affecting the lighting effect, and causing a short circuit in the circuit system.

[0044] Combination Figure 7 and Figure 8 The lamp body 2 has a lamp cavity, the light source module is located inside the lamp cavity, and the lamp body 2 is provided with the aforementioned socket 21, which penetrates the lamp body 2 and communicates with the lamp cavity. Combined with... Figure 9 When the lamp body 2 is assembled with the tensile wire harness 1, the elastic locking arm 1211 of the connecting part 121 is inserted into the socket 21. As the connecting part 121 is inserted into the socket 21, the protruding end of the elastic locking arm 1211 is pressed against the wire sheath 12 and elastically moves to the retracted position to ensure the smooth insertion of the connecting part 121. When the elastic locking arm 1211 passes through the socket 21 and enters the lamp cavity as the connecting part 121 is inserted, the elastic locking arm 1211 elastically returns to the open position, the step part 1213 is located in the socket 21, and the limiting baffle 1212 is still located outside the socket 21. At this time, the locking position 120 formed by the protruding end of the elastic locking arm 1211 and the limiting baffle 1212 engages with the surrounding structure of the socket 21, thereby restricting the axial movement of the connecting part 121 along the socket 21 and preventing the connecting part 121 from disengaging from the socket 21, thus achieving the tensile effect of the tensile wire harness 1. With the cooperation of the elastic clamp 1211 and the limiting baffle 1212, the assembly of the tensile wire harness 1 and the lamp body 2 is more convenient and faster, and no additional parts are required during assembly, which improves the assembly efficiency of the lamp 100 and reduces production costs.

[0045] Furthermore, the lamp body 2 has a countersunk hole 22 inside the socket 21 (i.e., inside the lamp cavity), and the countersunk hole 22 communicates with the socket 21; when the connecting part 121 is assembled with the socket 21, the protruding end of the elastic retaining arm 1211 is located inside the countersunk hole 22. The design of the countersunk hole 22 can effectively prevent the protruding end of the tensile wire harness 1 from being accidentally pushed during the assembly of the lamp 100, causing the connecting part 121 to detach from the socket 21.

[0046] Combination Figure 10 A notch is provided on one of the limiting baffle 1212 and the lamp body 2, and a protrusion 23 is provided on the other, so that when the connecting part 121 is assembled with the socket 21, the protrusion 23 is inserted into the notch. In this embodiment, the limiting baffle 1212 is provided with a notch (i.e., the limiting part 12121), and the lamp body 2 is provided with a protrusion 23; wherein, the notch may be recessed from the limiting surface of the limiting baffle 1212 facing the elastic locking arm 1211 away from the elastic locking arm 1211 but not through the limiting baffle 1212; of course, the notch may also directly penetrate the limiting baffle 1212 (as in this embodiment). It is understood that in other embodiments, a protrusion 23 may be provided on the limiting baffle 1212, and a notch matching the protrusion 23 may be provided on the lamp body 2. In this case, the position of the protrusion 23 may be designed according to the setting position of the notch on the lamp body 2. For example, the protrusion 23 may protrude from the limiting surface of the limiting baffle 1212 toward the elastic locking arm 1211, or it may protrude from the peripheral wall of the limiting baffle 1212 toward the outside of the limiting baffle 1212. This design can prevent the tension wire harness 1 from rotating relative to the socket 21 after it is installed on the lamp body 2, thereby avoiding the core 11 from being twisted and providing protection for the tension wire harness 1.

[0047] Furthermore, the number of elastic clips 1211 is preferably controlled to be two to four, and the two to four elastic clips 1211 are distributed circumferentially along the wire sheath 12, and the two to four elastic clips 1211 are evenly distributed. By designing the number of elastic clips 1211, on the one hand, it can ensure a firm connection between the tensile wire harness 1 and the lamp body 2 and have excellent tensile strength, and on the other hand, it can simplify the structure of the tensile wire harness 1 and make it easier to disassemble the tensile wire harness 1 and the lamp body 2.

[0048] Furthermore, in some embodiments (see [reference]), Figures 4 to 6 The wire sheath 12 is also integrally formed with a wiring structure. The limiting baffle 1212 is located between the elastic clamping arm 1211 and the wiring structure, that is, the wiring structure is set near the second end of the tensile wire harness 1. The wiring structure is a wire fixing part 131, which is provided with a slot 1311. The wire fixing part 131 can be used to quickly engage and connect the power box of the power module 14, realize the initial positioning and fixing of the power box of the tensile wire harness 1, and improve the assembly efficiency of the tensile wire harness 1 and the power box.

[0049] In some embodiments (see Figure 11 The wiring structure is a plug 132, for example, a male plug / female plug, which allows it to be quickly connected and assembled with the female plug / male plug 141 on the power module 14, simplifying the connection method between the tensile harness 1 and the power module 14 and reducing the difficulty of connecting the tensile harness 1 and the power module 14.

[0050] In some embodiments (see Figure 12 Alternatively, a power module 14 can be installed at the second end of the tensile harness 1 at the factory (i.e., the limiting baffle 1212 is located between the elastic clamp arm 1211 and the power module 14), wherein the power module 14 is electrically connected to the core 11. This design allows for improved ease of installation and use of the luminaire 100 when the power module 14 cannot be installed inside the luminaire 100, by configuring the power module 14 on the tensile harness 1.

[0051] In summary, by incorporating the tensile wire harness 1, the lamp 100 makes the assembly of the lamp body 2 and the tensile wire harness 1 more convenient and faster during the production process, reduces the number of assembly steps and required parts, thereby improving production efficiency and reducing production costs.

[0052] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
