Description

Technical Field

[0001] The invention relates to a waterproof lighting fixture, in particular to a waterproof lamp tube with a built-in power supply. Background Art

[0002] The lighting tube with built-in power supply in plastic shell is a commonly used lighting equipment, which includes a plastic transparent lampshade, an inlet end plug, a non-inlet end plug and an input line; to achieve the waterproof purpose of the lamp: the first step is to solve the waterproof problem of the inlet end (input line) and the inlet end plug, and the second step is to solve the waterproof problem of the assembly position of the inlet end plug, the non-inlet end plug and the plastic transparent lampshade.

[0003] At present, the incoming line end in the market needs to meet the requirements of anti-pulling and waterproofing. The mainstream technology is to add a waterproof joint to the incoming line plug to achieve the purpose of anti-pulling and waterproofing at the input line, or to inject the incoming line plug and the input line into one part to achieve waterproofing of the incoming line end. The mainstream waterproofing technology for the assembly position of the incoming line plug, the non-incoming line plug and the plastic light-transmitting cover is to apply a certain height of waterproof sealant on the bottom of the plug, and then assemble the plastic light-transmitting cover into the plug. The sealant fills the gap between the plug and the plastic light-transmitting cover to achieve waterproofing; or a waterproof structure is made on the outside of the plug and the plastic light-transmitting cover to achieve waterproofing of the plug and the plastic light-transmitting cover.

[0004] Although the above method can achieve the waterproof effect of the plastic shell with built-in power supply lighting tube, it still has certain defects when actually used:

[0005] (1) The waterproof connector at the incoming line is expensive and unsightly;

[0006] (2) The amount of waterproof glue applied at the assembly position of the inlet plug, the non-inlet plug and the plastic light cover is high, and the cost is high. In addition, due to the large inner cavity of the plastic light cover of the lamp tube, the waterproof glue is not squeezed, and the glue cannot evenly climb up along the inner and outer sides of the plastic light cover. If the amount of glue is slightly less or there are discontinuous breakpoints when applying the glue, poor waterproofing problems are likely to occur;

[0007] (3) The glue inside the plug is high, the climbing height is uneven, and a small proportion of the sealing gap is not filled, resulting in poor waterproofing. Summary of the invention

[0008] The object of the present invention is to provide a waterproof lamp tube with a built-in power supply, so as to solve the problems raised in the above-mentioned background technology.

[0009] To achieve the above object, the present invention provides a waterproof lamp tube with built-in power supply, comprising a plastic light-transmitting cover, an outlet outer plug, a non-outlet outer plug, an input cable, an outlet inner plug, a non-outlet inner plug, an EMI power module, a DC / DC power module, a connector, a light bar and a rubber wire sheath;

[0012] The outlet inner plug is inserted into one end of the plastic light-transmitting cover and cooperates with the EMI power module, and a waterproof sealant is filled between the outlet inner plug and the EMI power module; the non-outlet inner plug is inserted into the other end of the plastic light-transmitting cover and cooperates with the DC / DC power module, and a waterproof sealant is filled between the non-outlet inner plug and the DC / DC power module;

[0013] The outgoing line external plug is sleeved on one end of the plastic light-transmitting cover and matched with the outgoing line internal plug, and the non-outgoing line external plug is sleeved on the other end of the plastic light-transmitting cover and matched with the non-outgoing line internal plug;

[0014] The input cable passes through the outlet inner plug and the outlet outer plug and is connected to the EMI power module; there are two rubber sheaths, which are sleeved on the input cable and are respectively arranged at the contact between the input cable and the outlet inner plug and the contact between the input cable and the outlet outer plug;

[0015] The outer plug for outgoing wires, one end of the plastic light-transmitting cover, and the inner plug for outgoing wires form a first glue-dispensing groove, and the outer plug for non-outgoing wires, the other end of the plastic light-transmitting cover, and the inner plug for non-outgoing wires form a second glue-dispensing groove. The first glue-dispensing groove and the second glue-dispensing groove are independently filled with waterproof sealant.

[0016] Optimally, the depth of the first glue groove is the length of the plastic light-transmitting cover extending beyond the outer end of the inner plug for the outgoing line + the depth of the concave outer end of the inner plug for the outgoing line - 0.5 mm, and the depth of the second glue groove is the length of the plastic light-transmitting cover extending beyond the outer end of the inner plug for the non-outgoing line + the depth of the concave outer end of the inner plug for the non-outgoing line - 0.5 mm.

[0017] Furthermore, the width of the first glue-dispensing groove is greater than the sum of the wall thickness of the plastic light-transmitting cover and the wall thickness of the concave outer end of the outlet inner plug, and the width of the second glue-dispensing groove is greater than the sum of the wall thickness of the plastic light-transmitting cover and the wall thickness of the concave outer end of the non-outlet inner plug.

[0018] Optimally, the connector includes a connector body and snap-in protrusions formed on both end surfaces of the connector body, both ends of the light bar are provided with first snap-in holes that cooperate with the snap-in protrusions, and the EMI power supply module and the DC / DC power supply module are both provided with second snap-in holes that cooperate with the snap-in protrusions.

[0019] Optimally, it also includes a nylon tie, which is installed on the outer surface of the input cable.

[0020] Optimally, the outlet line inner plug and the outlet line outer plug, and the non-outlet line inner plug and the non-outlet line outer plug are also independently connected to each other by screws.

[0021] Optimally, the non-outlet internal plug and the outlet internal plug independently include a ring sleeve, a partition plate formed in the ring sleeve, a hook formed on the partition plate and extending inward, a groove formed on the inner wall of the ring sleeve, and a positioning groove formed on the outer wall of the ring sleeve. An input hole that cooperates with the input cable is provided on the partition plate of the outlet internal plug.

[0022] Furthermore, limiting protrusions cooperating with the partition plate are independently formed on the inner walls of the non-outlet external plug and the outlet external plug.

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] 1. The input cable is beautiful as a whole, low in weight, and convenient for process assembly;

[0025] 2. Improve product yield through multiple waterproofing;

[0026] 3. Waterproof sealant is filled between the outlet plug and the EMI power module to prevent water from penetrating into the lamp tube from the input cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0041] like Figures 1 to 13 The built-in power waterproof lamp tube shown mainly includes a plastic light-transmitting cover 1, an outlet external plug 2, a non-outlet external plug 3, an input cable 4, an outlet internal plug 5, a non-outlet internal plug 6, an EMI power module 7, a DC / DC power module 8, a connector 9, a light strip 10 and a rubber wire sheath 12.

[0042] The light bar 10 is arranged in the plastic light-transmitting cover 1, and its two ends are respectively connected to the EMI power module 7 and the DC / DC power module 8 through the connecting piece 9. Figure 7 As shown, the connector includes a connector body 91 and snap-in protrusions 92 formed on both end surfaces of the connector body 91, and both ends of the light strip 10 are provided with first snap-in holes that match the snap-in protrusions 92, and the EMI power supply module 7 and the DC / DC power supply module 8 are provided with second snap-in holes that match the snap-in protrusions 92, so that the light strip 10 is connected to the EMI power supply module 7 and the DC / DC power supply module 8 respectively through the connector 9.

[0043] The outgoing line internal plug 5 is inserted into one end of the plastic transparent cover 1 and cooperates with the EMI power module 7, and the space between the outgoing line internal plug 5 and the EMI power module 7 is filled with waterproof sealant (the filling requirements of the waterproof sealant can be found in the subsequent description); the non-outgoing line internal plug 6 is inserted into the other end of the plastic transparent cover 1 and cooperates with the DC / DC power module 8, and the space between the non-outgoing line internal plug 6 and the DC / DC power module 8 is filled with waterproof sealant (the filling requirements of the waterproof sealant can be found in the subsequent description).

[0044] The outgoing line external plug 2 is sleeved on one end of the plastic light-transmitting cover 1 and matched with the outgoing line internal plug 5 , and the non-outgoing line external plug 3 is sleeved on the other end of the plastic light-transmitting cover 1 and matched with the non-outgoing line internal plug 6 .

[0045] The structures of the outlet inner plug 5 and the non-outlet inner plug 6 are basically the same. Specifically, the outlet inner plug 5 includes a ring sleeve, a partition plate 54 formed in the ring sleeve (the partition plate 54 is formed on the inner wall of the ring sleeve and is perpendicular to its axis, and the partition plate 54 of the outlet inner plug 5 is provided with an input hole that matches the input cable 4), and a hook 52 formed on the partition plate 54 and extending inward (that is, the hook 52 extends in the direction of the light bar 10. At this time, the EMI power module 7 has a buckle that matches the hook 52, so as to achieve The inner plug 5 for the outlet line is connected with the EMI power module 7), a slot 52 is formed on the inner wall of the ring sleeve (the extension direction of the slot 52 is parallel to the axis of the ring sleeve, and it is located on the inner side of the partition plate 54 for inserting the EMI power module 7) and a positioning slot 53 is formed on the outer wall of the ring sleeve (the extension direction of the positioning slot 53 is also parallel to the axis of the ring sleeve, and a structure matching the positioning slot 53 can be provided on the outer wall of the end of the plastic transparent cover 1 to avoid relative rotation between the inner plug 5 for the outlet line and the plastic transparent cover 1). Similarly, the non-outgoing line inner plug 6 also includes a ring sleeve 60, a partition plate formed in the ring sleeve (the partition plate is formed on the inner wall of the ring sleeve 60 and is perpendicular to its axis), a hook 62 formed on the partition plate and extending inward (that is, the hook 62 extends in the direction of the light strip 10, and at this time the DC / DC power module 8 has a buckle that matches the hook 62, thereby realizing the matching connection between the non-outgoing line inner plug 6 and the DC / DC power module 8), a groove 62 formed on the inner wall of the ring sleeve (the extension direction of the groove 62 is parallel to the axis of the ring sleeve 60, which is located on the inner side of the partition plate and is used to insert the DC / DC power module 8) and a positioning groove 63 formed on the outer wall of the ring sleeve 60 (the extension direction of the positioning groove 63 is also parallel to the axis of the ring sleeve 60, and a structure matching the positioning groove 63 can be set on the outer wall of the end of the plastic transparent cover 1 to avoid relative rotation between the non-outgoing line inner plug 6 and the plastic transparent cover 1). In addition, the outgoing line internal plug 5 and the outgoing line external plug 2, the non-outgoing line internal plug 6 and the non-outgoing line external plug 3 are also independently connected to each other by screws 13. Note that the screws 13 do not penetrate the outgoing line internal plug 5 and the non-outgoing line internal plug 6.

[0046] In this embodiment, the structures of the outgoing line external plug 2 and the non-outgoing line external plug 3 are basically the same. Specifically, one end of the outgoing line external plug 2 is open and the other end is closed, that is, the other end has an end cover plate 21, so that a limiting protrusion 22 (the limiting protrusion 22 is preferably a ring-shaped structure) that matches the partition plate 54 is formed on the inner wall of the end cover plate 21; the difference is that an access hole that matches the input cable line 4 is opened at the center of the end cover plate 21. The non-outgoing line external plug 3 is also open at one end and closed at the other end, that is, the other end has an end cover plate, so that a limiting protrusion 31 that matches the partition plate (non-outgoing line internal plug 6) is formed on the inner wall of the end cover plate, and the limiting protrusion 31 is selected as a ring-shaped structure.

[0047] The input cable 4 passes through the outlet inner plug 5 and the outlet outer plug 2 and is connected to the EMI power module 7 (the connection method is welding); there are two rubber sheaths 12, which are sleeved on the input cable 4 and are respectively arranged at the contact point between the input cable 4 and the outlet inner plug 5 (that is, the input hole of the partition plate 54) and the contact point between the input cable 4 and the outlet outer plug 2 (that is, the access hole of the end cover plate 21), so as to ensure the sealing between the input cable 4 and the outlet inner plug 5 and the outlet outer plug 2.

[0048] In this embodiment, the waterproof lamp tube with built-in power supply further includes a nylon cable tie 11 , which is installed on the outer surface of the input cable 4 .

[0049] In this embodiment, the outgoing line external plug 2 and one end of the plastic light-transmitting cover 1 and the outgoing line internal plug 5 form a first glue-dispensing groove 23, and the non-outgoing line external plug 3 and the other end 1 of the plastic light-transmitting cover and the non-outgoing line internal plug 6 form a second glue-dispensing groove 32, and the first glue-dispensing groove 23 and the second glue-dispensing groove 32 are independently filled with waterproof sealant. In this embodiment, the depth of the first glue-dispensing groove 23 is the length of the plastic light-transmitting cover 1 extending out of the outer end of the outgoing line internal plug 5 + the depth of the concave outer end of the outgoing line internal plug 5 - 0.5mm, and the depth of the second glue-dispensing groove 32 is the length of the plastic light-transmitting cover 1 extending out of the outer end of the non-outgoing line internal plug 6 + the depth of the concave outer end of the non-outgoing line internal plug 6 - 0.5mm. The width of the first glue dispensing groove 23 is greater than the sum of the wall thickness of the plastic light-transmitting cover 1 and the wall thickness of the outer end of the inner plug 5 for the outlet line, and the width of the second glue dispensing groove 32 is greater than the sum of the wall thickness of the plastic light-transmitting cover 1 and the wall thickness of the outer end of the inner plug 6 for the non-outlet line (considering the diameter of the glue dispensing needle for convenient and quick dispensing, the width of the first glue dispensing groove 23 and the second glue dispensing groove 32 are finally selected to be about 3.5 mm).

[0050] The waterproof principle and assembly method of the waterproof lamp tube with built-in power supply of the present invention are as follows:

[0051] (a) First assemble the input line side: assemble the input cable 4, the outlet outer plug 2, the outlet inner plug 5, the rubber sheath 12 (two pieces), the nylon tie 11 and the EMI power module 7 into Figure 2 . When the input cable 4 passes through the outlet plug 2 and the outlet plug 5, a rubber cable sheath 12 is put on the outlet plug 2 and the outlet plug 5, and the input cable 4 is welded to the input pad of the EMI power module 7; a nylon tie 11 is assembled on the insulating outer skin of the input cable 4 close to the EMI power module 7 (to achieve the purpose of anti-pulling); the EMI power module 7 is assembled into the outlet plug 5, and the outlet plug 5 has a hook 51 that is inserted into the slot of the EMI power module 7 to achieve assembly. After assembly, waterproof sealant is poured into the outlet plug 5, and the height of the waterproof sealant must exceed the height of the input pad of the EMI power module 7. After the waterproof sealant dries, the following purposes are achieved: (1) prevent water from penetrating into the EMI power module 7 from the bare copper wire or insulation skin of the input cable 4; (2) prevent water from penetrating into the EMI power module 7 from the input hole of the outlet plug 5 and the access hole of the outlet plug 2; (3) the waterproof sealant can fix the EMI power module 7.

[0052] (b) Then assemble the non-input line side: Figure 3 As shown, the non-outlet inner plug 6 is assembled with the DC / DC power module 8. Similarly, the non-outlet inner plug 6 has a hook 61 (such as Fig. 9 As shown in the figure, the DC / DC power module 8 is inserted into the card slot of the DC / DC power module 8 for assembly. After assembly, waterproof sealant is poured into the non-outlet inner plug 6. At this time, the height of the glue filling only needs to exceed the position of the card hook 61, thereby playing the role of fixing the DC / DC power module 8.

[0053] (c) Reassemble the power supply (including the EMI power supply module 7 and the DC / DC power supply module 8) and the light bar 10: Connect the glued EMI power supply module 7 and the DC / DC power supply module 8 through the connector 9 (such as Figure 7 As shown in FIG. 1 , the power module is fixed to the light bar 10, and the electrical connection between the power module and the light bar 10 is achieved by wire welding. Figures 4 to 6 shown.

[0054] (d) Then assemble the plastic light-transmitting cover 1: Figure 5 and Figure 6 After the light bar 10 is assembled with the power module, since the outer diameter of the inner plug (including the outlet inner plug 5 and the non-outlet inner plug 6) is smaller than the inner diameter of the plastic light-transmitting cover 1, the outlet inner plug 5 and the non-outlet inner plug 6 are assembled and inserted into the plastic light-transmitting cover 1, and the length of the plastic light-transmitting cover 1 exceeds the length of the inner plug (each side exceeds by more than 2mm), so that the inner plug, the power supply, and the light bar 10 are all placed in the plastic light-transmitting cover 1. Figure 8 shown.

[0055] (e) Finally, assemble the outgoing line external plug 2 and the non-outgoing line external plug 3: fill the glue groove (i.e., the first glue groove 23) of the outgoing line external plug 2 with RTV low-flow waterproof sealant, and use screws 13 to fix the outgoing line internal plug 5, the plastic transparent cover 1, and the outgoing line external plug 2 (the outgoing line internal plug 5 has reserved screw holes, and the screw holes are closed holes, not perforated holes, to prevent water from seeping into the power supply).

[0056] like Figures 10 to 13 As shown, a full circle of glue dispensing grooves (i.e., the first glue dispensing groove 23 and the second glue dispensing groove 32) are designed at the bottom of the outer plug 2 for outgoing wires and the non-outgoing wires plug 3. The depth of the glue dispensing groove is designed to be the length of the outer edge (i.e., the outer end) of the plastic light-transmitting cover 1 beyond the outer edge of the inner plug 5 for outgoing wires + the depth of the inner concave outer end of the inner plug 5 - 0.5mm. The width of the glue dispensing groove is selected to be greater than the wall thickness of the plastic light-transmitting cover 1 + the wall thickness of the inner concave outer end of each inner plug; and considering the diameter of the glue dispensing needle for convenient and quick dispensing, the final selection is about 3.5mm.

[0057] like Fig.13 As shown, the waterproof principle of the outer plug end (i.e., the outlet end) is introduced as follows: when the first glue-dispensing groove 23 in the outlet outer plug 2 is filled with RTV waterproof sealant and assembled, since the plastic transparent cover 1 is longer than the outlet inner plug 2 after assembly, when the outlet outer plug 2 is assembled, the colloid in the first glue-dispensing groove 23 of the outlet outer plug 2 first contacts the plastic transparent cover 1, and when the glue is squeezed by the volume of the plastic transparent cover 1, it spreads around, and climbs upward due to the resistance of the inner wall of the first glue-dispensing groove 23. During the climbing process, the glue encounters the inner concave edge of the outer side of the outlet inner plug 2. At this time, the glue in the first glue-dispensing groove 23 is squeezed by the wall thickness volume of the plastic transparent cover 1 and the outlet inner plug 5 during the assembly process. After the glue is squeezed, it climbs upward and around under the resistance of the inner wall of the first glue-dispensing groove 23 (i.e., the limiting protrusion 22). The colloid climbs to fill the following gaps to achieve waterproofing:

[0058] The gap between the outer diameter of the plastic light-transmitting cover 1 and the inner diameter of the outlet external plug 2;

[0059] The gap between the end surface of the plastic light-transmitting cover 1 and the bottom of the outlet external plug 2;

[0060] The gap between the inner diameter of the plastic light-transmitting cover 1 and the outer diameter of the outlet inner plug 5;

[0061] The cavity where the inner diameter of the plastic light-transmitting cover 1 and the outer concave surface of the outlet inner plug 5 are in contact with the glue;

[0062] Since the outer concave side walls of the plastic light-transmitting cover 1 and the inner plug 5 of the outlet are deeply inserted into the glue dispensing groove during the design, the above gaps will be filled in the process of the RTV waterproof sealant climbing, achieving four-fold waterproofing, thereby greatly improving the waterproofing effect. Since the wall thickness and volume of the plastic light-transmitting cover 1 and the inner plug 5 of the outlet are much larger than the gaps in the above four positions, and the resistance increases after the glue climbs to a certain height, the height of the inner groove wall of the glue dispensing groove of the outer plug 2 of the outlet and the reserved gap at the bottom of the outer concave side of the inner plug 5 of the outlet will cause the excess glue to fill along the inner groove edge of the glue dispensing groove of the outer plug 2 of the outlet toward the direction of the input cable 4. In this way, the input cable 4 also achieves two-fold waterproofing: (1) glue is poured into the inner plug 5 of the outlet; (2) RTV sealant fills the surrounding of the input cable. The waterproofing principle of the non-outlet end is similar to that of the outlet end, so it will not be introduced again.

[0063] Therefore, through the above structural design, the built-in power waterproof lamp tube achieves multiple waterproofing, preventing the phenomenon that poor waterproofing of a single position will cause poor waterproofing of the lamp tube, greatly improving the waterproofing yield effect and achieving the waterproofing purpose.

[0064] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
