Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of LED driver power connection devices. More specifically, the present invention relates to an LED driver power supply with a pluggable waterproof terminal and its production process. Background Art
[0002] Common structures and production methods of LED driver power supplies are as follows: 1. Threaded sealed joint combined with glue sealing structure (such as PG / M series).
[0003] The cable is directly welded to the driver power supply PCB board, and then a threaded joint with a rubber sealing ring is installed on the driver power supply housing. After the cable passes through the joint, it is tightened by screwing to achieve waterproofing by using the rubber sealing ring.
[0004] Advantages: Good waterproof effect, supports cable replacement; Disadvantages: (1) Installation depends on manual screwing, which is time-consuming and prone to loosening and failure due to vibration; (2) The cable diameter needs to strictly match the joint specification, with poor flexibility; (3) The cable needs to pass through the reflow soldering or manual soldering with the PCB board, resulting in low production efficiency; (4) The cable specification needs to completely match the customer requirements, and it cannot be mass-produced standardly.
[0005] 2. Cable tail wire clip fixation combined with glue sealing structure.
[0006] The cable is directly welded to the driver power supply PCB board, then the cable tail wire clip is installed on the driver power supply housing, and finally it is fixed and sealed with potting glue (epoxy resin / silicone).
[0007] Advantages: Low material cost (saving connectors); Disadvantages: (1) Installation depends on manual threading and clamping, which is time-consuming and prone to loosening and failure due to vibration; (2) The cable diameter needs to strictly match the cable tail wire clip specification, with poor flexibility; (3) In actual use, cables of different lengths and specifications are required, resulting in the driver power supply being unable to be mass-produced standardly due to cable standard differences, affecting production efficiency (4) The cable needs to pass through the reflow soldering or manual soldering with the PCB board, resulting in low production efficiency.
[0008] In summary, the two existing driver power supplies have the following problems: (1) Both need to be reflow soldered with the PCB together with the cable, affecting production efficiency; (2) The cable is reflow soldered together with the PCB. It is required that the outer covering material of the cable (such as PVC / TPU) needs to undergo additional high-temperature resistance treatment; (3) The customization requirements are too high. The cable specifications required by each customer are different, and mass production cannot be carried out; (4) As a component of the lamp, if the drive power supply is damaged, only the input and output cables can be damaged to replace the drive power supply, which increases the replacement cost; (5) The installation of the cable is highly dependent on labor.
[0009] Therefore, how to overcome the above technical drawbacks while ensuring the sealing performance is the technical problem to be solved by the present invention. Summary of the Invention

[0021] A production process of an LED driving power supply with a pluggable waterproof terminal is as follows: S1: Weld the male terminal on the PCB of the driving power supply to make the driving power supply board; S2: Install the driving power supply board on the upper shell to complete the installation of the driving power supply board and the upper shell; S3: Install the second sealing member on the slot of the lower shell, and connect the lower shell and the upper shell, so that the second sealing member abuts against the driving power supply board and the male terminal is located in the slot, and then pot the glue in an inverted state to make the power supply housing; S4: Select a cable with a corresponding specification according to the customer's requirements, integrally form the cable and the plug end by injection molding.

Specific embodiments
[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.
[0034] It should be understood that the terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.
[0035] As shown in the figure, the present invention provides an LED driving power supply with a pluggable and waterproof terminal, including: a plug module 1, a power supply housing 2 and a driving power supply board 3; The driving power supply board 3 is arranged in the power supply housing 2; The plug module 1 is detachably connected to the power supply housing 2; After the plug module 1 is connected to the power supply housing 2, the plug module 1 is electrically connected to the driving power supply board 3, and the plug module 1 seals the power supply housing 2.
[0036] The plug module 1 is composed of a cable 11 and a plug end 12. The cable 11 extends from one end of the plug end 12 to the inside of the plug end 12 and is connected to a female terminal 4 arranged at the other end of the plug end 12. The plug end 12 is provided with an installation groove, and the female terminal 4 is located in the installation groove. The cable 11 extends into the installation groove to be connected to the female terminal 4. In order to ensure that the female terminal 4 and the male terminal 31 can be in close contact during connection and ensure the conductive effect, the female terminal usually needs to be designed separately. See the following embodiments for details. The plug end 12 is detachably connected to the power supply housing 2. The cable 11 and the plug end 12 are integrally formed by injection molding. Since the plug module 1 is produced separately, plug modules 1 with different cable specifications can be mass-produced according to different cable specifications, thereby realizing the mass production of the plug module 1.
[0037] The outer wall of the plug end 12 is provided with an accommodation groove in the circumferential direction, and a first seal 13 is arranged in the accommodation groove, as Figure 4 and Figure 5 shown. The first seal 13 is usually a conical silica gel seal ring that is larger at the top and smaller at the bottom. The conical structure design can be deformed under pressure when the plug end 12 is inserted into the power supply housing 2, so as to form a radial seal with the reserved interface (jack or slot 5) of the power supply housing 2, playing a role in waterproofing.
[0038] A male terminal 31 is arranged on the driving power board 3, and the male terminal 31 is directly welded to the PCB of the driving power supply. When the plug end 12 is connected to the power supply housing 2, the male terminal 31 is connected to the female terminal 4 in the installation groove of the plug end 12.
[0039] Furthermore, the male terminal 31 can be a pin such as a spring pin (Pogo Pin), a blade pin, a spring piece pin, etc.
[0040] The power supply housing 2 is composed of an upper shell 21 and a lower shell 22, as Figure 3 and Figure 4 shown. The bottom of the upper shell 21 is provided with a concave accommodation space, the driving power board 3 is located in the accommodation space, the side of the driving power board 3 away from the male terminal 31 (the top surface of the driving power board 3) is connected to the inner top surface of the accommodation space, and the lower shell 22 is connected to the bottom of the upper shell 21. The connection between the lower shell 22 and the upper shell 21 can be any connection method such as screw connection, snap connection or bonding.
[0041] Preferably, the lower shell 22 is provided with a potting port 23. After the upper shell 21 and the lower shell 22 are assembled together, glue is poured into the interior of the power supply housing 2 through the potting port 23, as Figure 3 shown, to realize the connection between the upper shell 21 and the lower shell 22. After the potting is completed, the potting port 23 can be sealed by a sealing plate 24, as Figure 2 shown.
[0042] The lower shell 22 is provided with jacks, and the number of the jacks is adapted to the number of the plug modules 1. The plug end 12 is connected to the lower shell 22 through the jacks. When the plug end 12 is inserted into the jacks, the conical first seal 13 will be deformed under pressure, filling the gap to seal the jacks, blocking the entry of external water vapor, so as to achieve the effects of waterproofing and fixing.
[0043] Furthermore, a slot 5 extending in the direction of the driving power board 3 is arranged on the plane of the lower shell 22 facing the accommodation space. The number of the slots 5 is adapted to the number of the jacks, and the slots 5 and the jacks located on the same central axis are interconnected, that is, the opening of the slot 5 on the lower shell 22 is regarded as a jack.
[0044] To increase the stability and sealing performance of the connection of the plug end 12, the inner wall of the slot 5 is a tapered shape that is smaller at the top and larger at the bottom. When the plug end 12 is connected to the lower shell 22, the plug end 12 is located within the slot 5, and the tapered first seal 13 is located between the outer wall of the plug end 12 and the inner wall of the slot 5 for sealing the slot 5.
[0045] Furthermore, to increase the firmness of the connection between the plug end 12 and the slot 5, a clamping member 6 is provided on the inner side wall of the jack (i.e., the opening of the slot 5 on the lower shell 22). The clamping member 6 extends towards the direction of the driving power supply board 3, so that the clamping member 6 can be hidden within the lower shell 22 and will not protrude from the lower shell 22 to avoid accidental contact.
[0046] A mating member 7 is provided on the outer side wall of the plug end 12. The mating member 7 can cooperate with the clamping member 6. The clamping member 6 and the mating member 7 can be a snap-fit structure. For example, Figure 3 and Figure 4 as shown, the clamping member 6 is a clamping plate with a limiting hole, and the mating member 7 is a clamping platform 121 protruding from the outer side wall of the plug end 12. The clamping member 6 and the mating member 7 appear in a set. In addition to the snap-fit combination, any other mating forms that can achieve the detachable connection between the plug end 12 and the inner wall of the slot 5, such as rotary locking snap-fits, press-unlock snap-fits, and threaded quick-release structures, should be included within the protection scope of the present invention.
[0047] To further increase the sealing performance, a second seal 8 is provided on the end face (top end face) of the slot 5 close to the driving power supply board 3. As Figure 5 shown, the plane of the driving power supply board 3 provided with the male terminal 31 is connected to the end face of the slot 5 through the second seal 8. The male terminal 31 of the driving power supply board 3 is located within the second seal 8 and extends into the slot 5. The second seal 8 can be an O-ring. When the lower shell 22 and the upper shell 21 are installed together, the end faces of the driving power supply board 3 and the slot 5 jointly squeeze the second seal 8, thereby achieving further sealing of the slot 5.
[0048] Working principle and beneficial effects of the above technical solution: Through the design of the above structure, the limitations in the use of the cable 11 in the prior art are solved, and the need for the LED waterproof power supply to be unable to replace different cables 11 is solved. The plug end 12 and the cable 11 are injection-molded into an integrated body, which can omit the steps of manual welding and manual plug-in, and improve production efficiency. The drive power board 3 and the plug module 1 are produced separately, and the drive power board 3 can be used as a standard part to achieve large-scale mass production of the drive power board 3. When shipping, only the plug end 12 with the corresponding specification cable 11 needs to be inserted into the power supply housing 2. The drive power supply housing 2 and the plug module 1 can adopt a snap structure (one of the implementation manners of the snap member 6 and the mating member 7) to achieve locking with one insertion, anti-vibration and anti-loosening. In this way, it not only meets the different customers' differentiated requirements for the cable 11, but also can mass-produce the plug module 1, improve the overall production efficiency of the drive power supply, and reduce the production cost. At the same time, as a fitting of the lamp, the present invention adopts a quick-release structure combined with the snap member 6 and the mating member 7. If the cable 11 or the drive power board 3 is damaged, it can be quickly disassembled and assembled, the accessories can be quickly replaced, and the installation and disassembly costs can be reduced.
[0049] In the foregoing embodiment, we mentioned that the male terminal 31 and the female terminal 4 adopt a quick connection form of plugging. In the actual application process, there are problems such as poor contact and small contact area between the female terminal 4 and the male terminal 31. To solve the technical problem of poor contact, we set the female terminal 4 as an elastic metal part to compensate for the insertion and extraction tolerance, so that the female terminal 4 and the male terminal 31 form a tight fit.
[0050] Furthermore, to solve the technical problem of small contact area, the present invention adopts the form of arranging a plurality of male terminals 31, such as Figure 3 shown. For this reason, the male terminal 31 uses an implementation manner of one row or multiple rows of pins. By greatly increasing the number of male terminals 31, the negative impacts brought by poor contact and small contact area are reduced. Because the form of pins is adopted, if the pressing force of the female terminal 4 on the male terminal 31 is too large, the male terminal 31 will be bent, which will lead to poor contact and reduction of the contact area. Therefore, it is necessary to optimize the structure of the female terminal 4, and we provide two different implementation manners of the female terminal 4.
[0051] In the first implementation manner, as Figure 5 and Figure 6As shown, the contact between the female terminal 4 and the male terminal 31 is unilateral. A first abutting groove for installing the female terminal 4 is provided on the side wall of the installation groove. The female terminal 4 is composed of a first connection end 411 and four abutting segments, namely a first abutting segment 412, a second abutting segment 413, a third abutting segment 414, and a fourth abutting segment 415. The first connection end 411 is arranged on the first abutting segment 412 and is used for connecting with the cable 11. The first abutting segment 412 abuts against the inner side wall of the first abutting groove. One end of the first abutting segment 412 is located at the inner bottom of the first abutting groove, and the other end is connected to one end of the second abutting segment 413. The second abutting segment 413 abuts against the inner top of the first abutting groove. The other end of the second abutting segment 413 is connected to one end of the third abutting segment 414. The third abutting segment 414 extends away from the first abutting segment 412 and abuts against the side wall of the male terminal 31, thereby realizing the electrical connection between the female terminal 4 and the male terminal 31. The other end of the third abutting segment 414 is connected to one end of the fourth abutting segment 415. The other end of the fourth abutting segment 415 extends towards the first abutting segment 412 and abuts against the first abutting segment 412, as Figure 5 and Figure 6 shown.
[0052] When the male terminal 31 is not in contact with the third abutting segment 414, the abutting surface of the third abutting segment 414 (with respect to the male terminal 31) extends towards the central axis direction of the male terminal 31 (pin), and there is a non-zero angle between the third abutting segment 414 and the second abutting segment 413; When the male terminal 31 moves downward and inserts into the installation groove, the bottom surface of the male terminal 31 first contacts the third abutting segment 414. As the male terminal 31 moves downward, the third abutting segment 414 is squeezed and moves towards the first abutting segment 412, and squeezes the fourth abutting segment 415. The fourth abutting segment 415 squeezes the first abutting segment 412 until the male terminal 31 is completely inserted into the installation groove. The third abutting segment 414 squeezes against the side wall of the male terminal 31, realizing the tight connection between the female terminal 4 and the male terminal 31.
[0053] Furthermore, in order to prevent the male terminal 31 (pin) from being bent and deformed, a limiting member 416 is provided on the first abutting segment 412. The limiting member 416 extends from the first abutting segment 412 towards the male terminal 31 and abuts against the inner side wall of the installation groove (opposite to the first abutting groove). The limiting member 416 is L-shaped or C-shaped. When the male terminal 31 is inserted into the installation groove and is squeezed by the third abutting segment 414, it will abut against the inner side wall of the limiting member 416 (opposite to the third abutting segment 414), thereby preventing the male terminal 31 from being squeezed and deformed. Thus, the female terminal 4 can use a relatively large pressure to restrain the male terminal 31 without worrying about the male terminal 31 being squeezed and deformed.
[0054] Further, a support ring 417 is provided at the bottom of the first abutting section 412. The support ring 417 is sleeved outside the cable 11 and extends towards the inner wall of the installation groove (opposite to the first abutting groove). Since the present embodiment is in the form of single-sided contact, in order to prevent the female terminal 4 from toppling in the first abutting groove, resulting in the male terminal 31 being unable to be inserted, it is necessary to provide the support ring 417 to support the female terminal 4. The bottom of the support ring 417 abuts against the inner bottom surface of the installation groove and the inner bottom surface of the first abutting groove, as Figure 5 shown.
[0055] In the second embodiment, a bilateral clamping method is adopted. In this embodiment, two second abutting grooves are symmetrically provided on the two opposite inner walls of the installation groove. A clamping platform 121 is provided at the inner bottom of the installation groove. The number of female terminals 4 is two, which are respectively located in the two second abutting grooves and on both sides of the clamping platform 121. The female terminal 4 is composed of a second connection end 421 and four abutting sections. The four abutting sections are respectively a fifth abutting section 422, a sixth abutting section 423, a seventh abutting section 424, and an eighth abutting section 425. The second connection end 421 is provided at the inner bottom of the second abutting groove. One end of the second connection end 421 is connected to the cable 11 (the second connection end 421 of the other female terminal is also connected to the cable 11, so that as long as any one of the female terminals 4 abuts against the male terminal 31, good electrical connection can be achieved). The other end extends towards the clamping platform 121 and is connected to one end of the fifth abutting section 422. The other end of the fifth abutting section 422 extends towards the driving power supply board 3 and is connected to one end of the sixth abutting section 423. The connection part between the fifth abutting section 422 and the sixth abutting section 423 is arc-shaped. The other end of the sixth abutting section 423 extends towards the clamping platform 121 and is connected to one end of the seventh abutting section 424. The connection part between the sixth abutting section 423 and the seventh abutting section 424 is arc-shaped. The seventh abutting section 424 abuts against the inner wall of the second abutting groove. The other end of the seventh abutting section 424 is connected to one end of the eighth abutting section 425. The other end of the eighth abutting section 425 extends towards the opening direction of the installation groove (at the plug end 12).
[0056] When the male terminal 31 is connected to the female terminal 4, as Figure 8As shown in (A), the fifth abutting sections 422 of the two female terminals 4 abut against the opposite side walls of the male terminal 31, the sixth abutting section 423 (close to the connection with the seventh abutting section 424) abuts against the fifth abutting section 422 (or the arc-shaped bending of the fifth abutting section 422 and the sixth abutting section 423 provides the fifth abutting section 422 with a force to clamp the male terminal 31), the seventh abutting section 424 abuts against the inner side wall of the second abutting groove, the fifth, sixth and seventh abutting sections are all in a stressed state, the eighth abutting section 425 has a gap (or is in contact) with the inner top of the second abutting groove, and at this time the eighth abutting section 425 is in a non-stressed state; When the male terminal 31 is pulled out upward, under the action of the clamping force of the two female terminals 4, the moving male terminal 31 will lift the female terminal 4 upward. At this time, the connection between the fifth abutting section 422 and the second connecting end 421 will be lifted, but the fifth abutting section 422 is always abutted against the side wall of the card platform 121. At this time, the eighth abutting section 425 abuts against the inner top surface of the second abutting groove, and the eighth abutting section 425 is in a stressed state. At the same time, since the female terminal 4 moves upward as a whole, and the connection between the second connecting end 421 and the cable 11 remains fixed, the connection between the second connecting end 421 and the fifth abutting section 422 will also be lifted upward, causing the second connecting end 421 to be deformed and in a stressed state. Then, the male terminal 31 continues to be pulled out upward, and the male terminal 31 will be displaced relative to the female terminal 4, and the contact area between the fifth abutting section 422 and the male terminal 31 will gradually decrease. Figure 8 As shown in (B) (the connection between the second connection end 421 and the cable 11, and the cable 11 are not shown). It can be seen that the double-sided clamping has a higher fault tolerance rate than the single-sided contact, allowing the length of the male terminal 31 to be inconsistent, and can still maintain good contact when a gap appears between the upper shell 21 and the lower shell 22 and there is a relative shaking up and down.
[0057] When the male terminal 31 is completely pulled out, Figure 8 As shown in (C), under the joint action of the eighth abutment section 425 and the second connection end 421, the female terminal 4 is reset, and the fifth abutment sections 422 of the two female terminals 4 abut together. Because the connection between the fifth abutment section 422 and the sixth abutment section 423 is arc-shaped, the insertion direction of the male terminal 31 can be guided when the male terminal 31 is inserted.
[0058] The present invention also provides a production process of an LED driving power supply with pluggable waterproof terminals, the steps of which are as follows: S1: Weld the male terminal 31 onto the PCB of the driving power supply to make a driving power supply board 3; S2: Install the driving power board 3 on the upper shell 21 to complete the installation of the driving power board 3 and the upper shell 21; S3: Install the second seal 8 on the slot 5 of the lower housing 22, connect the lower housing 22 to the upper housing 21, make the second seal 8 abut against the drive power board 3, and make the male terminal 31 located within the slot 5.
