Description

Technical Field

[0001] This application belongs to the field of lighting device technology, and more specifically, relates to a lamp housing and a lamp fixture. Background Technology

[0002] LED lights, as a new type of lighting source, have the advantages of energy saving, environmental protection, and high brightness, and are widely used in daily life. Currently, the wiring outlets of these lights generally use sealing rings or sealants to achieve a certain degree of waterproofing. However, during handling and installation, the light fixture wires are easily pulled laterally, or the sealing rings or sealants may age and crack after a period of use. This can lead to gaps between the wire and the sealing ring or sealant, damaging the sealing structure and causing a loss of waterproofing. Utility Model Content

[0003] The purpose of this application is to provide a lamp housing and lamp fixture to solve the technical problems of the lamp housing sealing structure being easily damaged and the waterproof effect being poor in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a lamp housing is provided, including a housing and a waterproof plug. The housing is provided with a wire passage channel, and the waterproof plug is inserted and fixed in the wire passage channel. The waterproof plug is provided with a wire passage hole for interference fit with an electric wire, and the wire passage hole has an opening.

[0005] Optionally, the waterproof plug has an outer edge, and the inner wall of the wire passage is provided with a boss, with the outer edge overlapping the inner end of the boss.

[0006] Optionally, the inner end of the boss has a guide slope, and the angle formed between the guide slope and the axis of the wire passage is 30° to 60°.

[0007] Optionally, the width of the opening is not greater than 1 / 3 of the diameter of the wire hole.

[0008] Optionally, the wall surface of the wire passage and the end face of the waterproof plug form a receiving groove, there are two receiving grooves, and at least one of the receiving grooves is provided with a waterproof seal.

[0009] Optionally, a support platform is provided on the inner wall of the housing, the wire passage passes through the support platform, and the outer wall of the support platform is conical.

[0010] Optionally, the angle between the outer wall of the support platform and the axis of the cable passage is 1° to 5°.

[0011] Optionally, the height of the waterproof plug is 1mm to 30mm.

[0012] Optionally, the waterproof plug is made of silicone or rubber.

[0013] This application also provides a lamp fixture, which includes a lamp body and a lamp housing as described above, wherein the lamp body is mounted on the housing and the wires of the lamp body are located in the wire hole.

[0014] The beneficial effects of the lamp housing provided in this application are as follows: Compared with the prior art, the lamp housing of this application has a wire passage channel in the housing, and a waterproof plug is inserted and fixed in the wire passage channel. The wire passage hole is located on the waterproof plug and has an opening. By setting the opening, the wire passage hole has a larger elastic deformation space to facilitate the installation of wires. Moreover, during the process of installing the waterproof plug into the wire passage channel, the opening shrinks, allowing the waterproof plug to better adapt to the dimensional deviation of the wire passage channel and ensure a tight fit. After installation, the waterproof plug is compressed, and the opening generates a greater rebound force, which can more tightly fill the gap between the outer wall of the waterproof plug and the inner wall of the wire passage channel, preventing water, dust, etc. from entering and improving the sealing effect of the waterproof plug.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0028] Please refer to the following: Figures 1 to 3 The lamp housing provided in this application embodiment will now be described. The lamp housing includes a housing 10 and a waterproof plug 20. The housing 10 has a wire passage 11, and the waterproof plug 20 is inserted and fixed within the wire passage 11. (See reference...) Figure 3 The waterproof plug 20 is provided with a wire hole 21 for interference fit with the wire 30, and the wire hole 21 has an opening 22.

[0029] The interior of the housing 10 is hollow, used to install the lamp body 100 and its control board, etc. Specifically, the housing 10 includes a box body 101 and a cover plate 102, with the cover plate 102 covering the open end of the box body 101. In one embodiment, the cover plate 102 and the box body 101 are connected by a snap-fit ​​connection. For example, one of the cover plate 102 and the box body 101 has a locking block, and the other has a locking groove; the locking block is inserted into the locking groove to fix the cover plate 102 to the box body 101. In another embodiment, the cover plate 102 and the box body 101 are fixedly connected by screws. To improve the sealing performance of the housing 10, a sealing ring is installed between the box body 101 and the cover plate 102. The sealing ring is a silicone ring or a rubber ring. In addition, the box body 101 and the cover plate 102 can also be fixedly connected by ultrasonic welding or sealant.

[0030] The cable passage 11 is located at the bottom of the housing 101. A waterproof plug 20 is inserted and fixed within the cable passage 11. In one embodiment, the waterproof plug 20 is inserted into the cable passage 11 with an interference fit. In another alternative embodiment, the waterproof plug 20 is fixedly installed within the cable passage 11 using sealant.

[0031] See Figure 3 The waterproof plug 20 has a wire passage hole 21, which is a through hole. The wire 30 is inserted into the wire passage hole 21. The diameter of the wire passage hole 21 is approximately the same as the diameter of the wire 30, ensuring a tight fit between the wire 30 and the waterproof plug 20. For example, the diameter of the wire passage hole 21 is less than 1 mm smaller than the diameter of the wire 30. (See reference...) Figure 3 The wire hole 21 has an opening 22, which connects the wire hole 21 to the outside of the waterproof plug 20. The opening 22 extends through the waterproof plug 20 along the axial direction of the wire hole 21.

[0032] During the assembly of the waterproof plug 20 and the housing 10, when the wire 30 is inserted into the wire hole 21, the wall of the wire hole 21 is compressed, and the opening 22 expands. This expansion space allows the wire 30 to pass through easily while ensuring effective contact between the wall of the wire hole 21 and the wire 30. When the waterproof plug 20 is inserted into the wire passage 11, the expansion space provided by the opening 22 allows the waterproof plug 20 to contract, ensuring an interference fit between the waterproof plug 20 and the inner wall of the wire passage 11.

[0033] Compared with the prior art, the lamp housing provided in this application has an opening 22 in the wire passage hole 21. By setting the opening 22, the wire passage hole 21 has a larger elastic deformation space to accommodate the installation of the wire 30. Moreover, during the process of installing the waterproof plug 20 into the wire passage channel 11, the opening 22 contracts, allowing the waterproof plug 20 to better adapt to the dimensional deviation of the wire passage channel 11 and ensure a tight fit. After installation, the waterproof plug 20 is compressed, and the opening 22 generates a greater rebound force, thereby more tightly filling the gap between the outer wall of the waterproof plug 20 and the inner wall of the waterproof wire passage channel 11, preventing water, dust, etc. from entering and improving the sealing effect of the waterproof plug 20.

[0034] In another embodiment of this application, the waterproof plug 20 is frustum-shaped, and correspondingly, the wire passage 11 is a circular hole. By setting the waterproof plug 20 to a frustum shape, it is convenient to insert it into the wire passage 11 and at the same time, it is convenient to demold the waterproof plug 20 during production. Specifically, the waterproof plug 20 is frustum-conical, with different dimensions at both ends. Correspondingly, the wire passage 11 can be a circular hole with a gradually changing diameter or a circular hole with a uniform diameter, as long as it ensures that the waterproof plug 20 can be inserted into the wire passage 11 and have an interference fit with the housing 10.

[0035] In another embodiment of this application, see [reference] Figure 3 , Figure 4 and Figure 5 The waterproof plug 20 has an outer edge 23, and a boss 12 protrudes from the inner wall of the wire passage 11. The outer edge 23 overlaps with the inner end face of the boss 12. By providing the boss 12 and the outer edge 23, the waterproof plug 20 is positioned and supported for insertion into the wire passage 11, thus improving the ease of installation. The inner end face of the boss 12 refers to the end of the boss 12 closest to the inside of the housing 10.

[0036] Optionally, the outer edge 23 is annular, extending around the circumference of the waterproof plug 20. Alternatively, the outer edge 23 includes a plurality of lugs spaced apart along the circumference of the waterproof plug 20. The outer edge 23 causes the waterproof plug 20 to form a first connecting segment and a second connecting segment connected in sequence, wherein the cross-sectional area of ​​the first connecting segment is larger than the cross-sectional area of ​​the second connecting segment. The cross-sections of the first and second connecting segments refer to the cross-sections obtained by the first and second connecting segments through a plane perpendicular to the axis of the through hole 21.

[0037] The boss 12 protrudes from the inner wall of the wire passage 11 and is arranged circumferentially. Similarly, the boss 12 may be arranged circumferentially around the wire passage 11 or may include multiple protrusions spaced circumferentially along the wire passage 11. The boss 12 creates a radially narrowed region within the wire passage 11. See also... Figure 5 The boss 12 causes the wire passage 11 to form a first channel 111, a radial narrowing channel 112 and a second channel 113 that are connected in sequence.

[0038] In this configuration, the axial length of the boss 12 along the wire passage 11 is the same as the length of the second connecting section; or, the axial length of the boss 12 along the wire passage 11 is slightly greater than the length of the second connecting section. After the waterproof plug 20 is inserted into the wire passage 11, the end of the waterproof plug 20 away from the outer edge 23 does not protrude above the boss 12. At this time, one end of the waterproof plug 20 is located within the first channel 111, and the other end is located within the constricted channel 112. Alternatively, the axial length of the boss 12 along the wire passage 11 can be less than the length of the second connecting section, so that one end of the waterproof plug 20 is located within the first channel 111, and the other end is located within the second channel 113.

[0039] In another embodiment of this application, see [reference] Figure 5 The inner end of the boss 12 has a guide slope 121, and the angle formed between the guide slope 121 and the axis of the wire passage 11 is 30° to 60°. Specifically, the guide slope 121 is used to guide the second connecting section of the waterproof plug 20 into the constriction channel 112. The angle between the guide slope 121 and the axis of the wire passage 11 is 30°, 60°, or any angle between 30° and 60°. Optionally, the angle formed between the guide slope 121 and the axis of the wire passage 11 is 40° to 50°. For example, the angle formed between the guide slope 121 and the axis of the wire passage 11 is 40°, 45°, or 50°. By providing the guide slope 121 on the boss 12, it is convenient to fix the waterproof plug 20 and at the same time, it is convenient to prevent the boss 12 from shrinking and deforming during demolding.

[0040] In another embodiment of this application, the width of the opening 22 is no greater than 1 / 3 of the diameter of the wire hole 21. If the width of the opening 22 is too large, it will affect the sealing performance of the waterproof plug 20. Therefore, the width of the opening 22 can be 1 / 3, 1 / 4 or 1 / 5 of the diameter of the wire hole 21, as long as it is not greater than 1 / 3 of the diameter of the wire hole 21.

[0041] In another embodiment of this application, see [reference] Figure 2 The wall surface of the wire passage 11 and the end face of the waterproof plug 20 form a receiving groove 14. There are two receiving grooves 14, and at least one receiving groove 14 is provided with a waterproof seal.

[0042] After the waterproof plug 20 is inserted into the wire passage 11, the wall of the second passage 113 and the end face of the waterproof plug 20 away from the outer edge 23 form a receiving groove 14. The wall of the first passage 111 and the end face of the waterproof plug 20 with the outer edge 23 form another receiving groove 14. Thus, receiving grooves 14 are formed on the side of the boss 12 near the inside of the housing 10 and on the side of the boss 12 near the outside of the housing 10, respectively. At least one waterproof sealant is installed in the two receiving grooves 14. For example, only the receiving groove 14 near the outside of the housing 10 is filled with sealant to form a waterproof sealant. After the wire 30 and the waterproof plug 20 are installed, the receiving groove 14 is located outside the housing 10, which facilitates the injection of sealant into the receiving groove 14 for sealing, making the operation convenient. Alternatively, before the housing 10 is sealed, filling the receiving groove 14 near the inside of the housing 10 with sealant to form a waterproof sealant can also improve the waterproof performance. Of course, sealant can also be filled into both receiving slots 14 to improve waterproof performance and strengthen the connection between the waterproof plug 20 and the housing 10.

[0043] Optionally, the waterproof sealant is made of sealant. During assembly, sealant is poured into the receiving groove 14 to form a waterproof sealant, sealing the wire passage 11. The lateral dimension of the receiving groove 14 is equal to the maximum cross-section of the waterproof plug 20, which facilitates the retention and accumulation of sealant when sealing the wire passage 11, preventing sealant leakage and reducing the sealing effect. As a result, the waterproof plug 20 can fit more tightly against the wall of the wire passage 11 when threading and inserting the wire, and prevents relative sliding between the wire 30 and the waterproof plug 20, and between the waterproof plug 20 and the housing 10, thus preventing the sealant from losing its waterproofness due to gaps caused by relative sliding.

[0044] In another embodiment of this application, see [reference] Figure 4 and Figure 5 A support platform 13 protrudes from the interior of the housing 10, and a wire passage 11 passes through the support platform 13. The support platform 13 is located at the bottom of the housing 101. The support platform 13 enhances the strength of the housing 10 at the wire passage 11 and provides an installation position for the waterproof plug 20. The outer wall 131 of the support platform 13 is tapered. Because the outer wall 131 of the support platform 13 is inclined relative to the axis of the wire passage 11, it facilitates demolding during the manufacturing of the housing 101.

[0045] In another embodiment of this application, the inclination angle between the outer wall 131 of the support platform 13 and the axis of the wire passage 11 is 1° to 5°. For example, the included angle formed between the outer wall 131 of the support platform 13 and the axis of the wire passage 11 is 1°, 5°, or any angle value between 1° and 5°. For example, the included angle formed between the outer wall 131 of the support platform 13 and the axis of the wire passage 11 is 3°.

[0046] In another embodiment of this application, there are multiple wire-passing holes 21, and at least some of the wire-passing holes 21 have openings 22. For example, each wire-passing hole 21 has an opening 22; or, some of the multiple wire-passing holes 21 have openings 22, while other parts do not have openings 22. See also Figure 3 There are three wire guide holes 21 arranged in a triangle, and each wire guide hole 21 has an opening 22. In addition, there can also be two or four wire guide holes 21, depending on the actual number of wires to be guided.

[0047] In another embodiment of this application, please refer to Figures 1 to 3 The height of the waterproof plug 20 is 1mm to 30mm. The height of the waterproof plug 20 refers to the maximum length of the waterproof plug 20 along the axial direction of the wire hole 21. Specifically, the height of the waterproof plug 20 can be 1mm, 3mm, 10mm, 30mm, or any value between 1mm and 30mm.

[0048] Optionally, the height of the waterproof plug 20 is 8mm to 12mm. For example, the height of the waterproof plug 20 can be 8mm, 10mm, or 12mm. Of course, the height of the waterproof plug 20 can also be any value between 8mm and 12mm, and this embodiment of the present invention does not specifically limit this. By limiting the height of the waterproof plug 20, the height of the waterproof plug 20 is made appropriate, which can not only provide support and guidance for the wire 30, but also ensure that the lamp housing has a good sealing effect, preventing moisture, humidity, and dust from entering the housing 10 and affecting the electrical connection structure inside the housing 10, thus reducing the risk of short circuit.

[0049] In another embodiment of this application, the waterproof plug 20 is made of an elastic material, which enables the waterproof plug 20 to be installed in the wire passage 11 and to have an interference fit with the wire 30. Optionally, the waterproof plug 20 is a silicone part or a rubber part.

[0050] This application also provides a lighting fixture, see reference. Figure 6 The lamp includes a lamp body 100 and a lamp housing as described above, with the lamp body 100 mounted on the housing 10. The wires 30 of the lamp body 100 are located in the wire hole 21.

[0051] The lamp is an appliance that provides illumination for household lighting, automotive lighting, etc. The lamp body 100 is connected to a control board, and a wire 30 is connected to the control board. The wire 30 passes through the wire hole 21 of the waterproof plug 20. The lamp body 100 is mounted on the cover plate 102 of the housing 10 and is electrically connected to the control board. The lamp body 100 can be installed inside or outside the housing 10. For example, as... Figure 6 As shown, the lamp body 100 is located outside the housing 10.

[0052] The lighting fixture provided in this application has an opening 22 in the wire hole 21 of the waterproof plug 20, which provides a larger elastic space for the wire hole 21, making it convenient for the wire 30 to be threaded through and for the waterproof plug 20 to be installed in the wire passage 11. The elasticity of the wire hole 12 allows the waterproof plug 20 to fully fit against the inner wall of the wire passage 11, thereby improving the sealing effect of the waterproof plug 20.

[0053] The lighting fixtures provided in this application embodiment were subjected to IP67 waterproof testing and pull-out verification. Taking a 3.0W automotive taillight as an example, two 3.0W automotive taillights were selected as test samples. The testing standard was IEC 60529, which requires that: in a laboratory with an ambient temperature of 25°C, the test sample be completely immersed in a container filled with water, with the lowest point of the test sample ≥1m above the water surface and the highest point of the test sample ≥0.15m above the water surface, for a soaking time of 30 minutes. After soaking, the test samples were removed, and it was required that no water had entered the test samples.

[0054] Before conducting the IP67 waterproof test, two car taillights were tested using an adjustable DC power supply to measure their respective power values. Under a constant DC voltage of 12V, both taillights conducted normally; the power measured for sample 1 was 3.0W, and the power measured for sample 2 was 3.1W.

[0055] Next, an IP67 waterproof test was conducted. In a laboratory with an ambient temperature of 25℃, two test samples were tied together with weights and submerged in a 1m deep water tank. The lowest point of the two test samples was 1m above the water surface, and the highest point was 0.91m above the water surface. The immersion time was 30 minutes. Afterward, they were removed and visually inspected to ensure there were no water stains inside the taillights. Using an adjustable DC power supply, both taillights were tested. Under a constant DC voltage of 12V, both taillights conducted normally without short circuits. The power test value of test sample 1 was 3.0W, and the power test value of test sample 2 was 3.1W, consistent with the test values ​​before the IP67 waterproof test.

[0056] Therefore, it was determined that the two test samples passed the test and met the IP67 waterproof test requirements in the IEC 60529 standard, thus complying with the product usage requirements.

[0057] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
