Description

Technical Field

[0001] This utility model relates to the field of LED light-emitting module technology, and in particular to an LED light-emitting module that prevents poor contact. Background Technology

[0002] In the field of lighting technology, LED light boards have been widely used in various lighting scenarios due to their many advantages such as energy saving, high brightness, long life and environmental protection. LED light boards are usually made by soldering multiple LED beads on a printed circuit board (PCB) in a certain arrangement and then matching them with corresponding circuits to achieve stable light emission function.

[0003] In actual installation, multiple LED light boards are connected in series according to usage requirements. Therefore, the connecting wires at both ends of the LED light board are connected to the connecting wires of adjacent LED light boards. However, the connection between the connecting cable and the main body of the LED light board is a relatively fragile link. During the production process, the connecting cable is usually connected to the light board by soldering or plugging. These connection methods are prone to loosening under external forces during long-term use. Moreover, the stress concentration phenomenon at the connection point is quite obvious. When the cable is subjected to external forces such as bending or stretching, the connection point bears a large force, which can easily lead to the solder joint falling off or the internal wires of the cable breaking. This can result in poor contact of the LED light board. When reconnecting the cable to the LED light board, it is necessary to disassemble the LED light fixture and re-solder it using soldering equipment, which is a cumbersome operation. Utility Model Content

[0004] The purpose of this invention is to provide an LED light-emitting module that prevents poor contact, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An LED light-emitting module for preventing poor contact includes a lamp board body, on which multiple LED beads are fixedly mounted. Multiple contacts are provided at both ends of the lamp board body, and these contacts are electrically connected to the multiple LED beads via wiring within the lamp board body. A connector is also fixedly mounted at both ends of the lamp board body. The connector includes a bottom shell and a top shell. A pressure cover is movably mounted on the top shell. A mounting groove is formed on one side of the pressure cover. A wire groove is formed inside the pressure cover above the mounting groove. An arc-shaped pressure plate is formed inside the wire groove, and an arc-shaped pressure block is movably mounted inside the wire groove. Two wire grooves are also formed on the top shell, and a buckle is fixedly mounted on the top shell between the two wire grooves.

[0007] As a further preferred embodiment of this utility model, the bottom shell and the top shell are fixedly connected to each other and fixedly installed at one end of the lamp panel body.

[0008] As a further preferred embodiment of this utility model, shaft holes are provided on both sides of the top shell. The cooperation between the top shell and the pressure cover can provide conditions for fixing one end of the cable, while the shaft holes provide conditions for connecting the pressure cover and the top shell.

[0009] As a further preferred embodiment of this utility model, a snap-fit ​​groove is provided in the pressure cap located between the two wire grooves. Two side blocks are fixedly installed at the lower end of the pressure cap. A rotating shaft is fixedly installed on the opposite side of the two side blocks, and the rotating shaft is rotatably installed in the corresponding shaft hole. That is, the pressure cap is rotatably installed on the top shell through two sets of side blocks and rotating shafts.

[0010] As a further preferred embodiment of this utility model, two arc-shaped pressure plates are fixedly installed inside the mounting groove. Each of the two arc-shaped pressure plates has a groove bent on one side. By setting two arc-shaped pressure plates made of metal, it is easy to apply pressure to one end of the cable, thereby ensuring that one end of the cable is always electrically connected to one of the contacts.

[0011] As a further preferred embodiment of this utility model, a T-shaped groove is provided on the inner side of the wire groove, and a T-shaped slider is fixedly installed on the arc-shaped pressure block. The T-shaped slider is slidably connected in one of the T-shaped grooves, and a compression spring is also installed in the T-shaped groove. One side of the compression spring abuts against one side of the T-shaped groove, and the other side of the compression spring abuts against one side of the T-shaped slider. By installing the arc-shaped pressure block in the wire groove through the T-shaped slider, when the arc-shaped pressure block is dragged by the cable, the arc-shaped pressure block drives the T-shaped slider to slide in the obliquely opened T-shaped groove. This reduces the distance between the arc-shaped pressure block and the cable by utilizing the height difference, thereby gradually increasing the pressure applied to the cable and preventing one end of the cable from detaching from the contact.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, a connector is fixedly installed at each end of the lamp panel body. The connector consists of a bottom shell, a top shell, and a pressure cover. Two arc-shaped pressure plates are provided on one side of the pressure cover to facilitate the cable to make contact with the corresponding contact point and make an electrical connection. This improves the convenience of maintaining and replacing the cable connected to the lamp panel body. In addition, two arc-shaped pressure blocks are provided on one side of the pressure cover, and T-shaped sliders are fixedly installed on the arc-shaped pressure blocks. The T-shaped sliders are slidably connected in the obliquely opened T-shaped grooves. This allows the cable to move the arc-shaped pressure blocks after being subjected to force, which in turn causes the T-shaped sliders to move obliquely in the T-shaped grooves. This increases the pressure applied to the cable by the arc-shaped pressure blocks, thereby preventing the cable from detaching from the top shell. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-5 As shown, the present invention provides an LED light-emitting module for preventing poor contact, including a lamp board body 1, on which multiple LED beads 2 are fixedly installed. Multiple contacts 3 are provided at both ends of the lamp board body 1, and the contacts 3 are electrically connected to the multiple LED beads 2 through the circuit inside the lamp board body 1. A connector 4 is also fixedly installed at both ends of the lamp board body 1. The connector 4 includes a bottom shell 5 and a top shell 6. A pressure cover 7 is movably installed on the top shell 6. An installation groove 8 is opened on one side of the pressure cover 7. A wire groove 9 is opened in the pressure cover 7 located above the installation groove 8. An arc-shaped pressure piece 10 is opened on the inner side of the wire groove 9, and an arc-shaped pressure block 11 is also movably installed in the wire groove 9. Two wire grooves 9 are also opened on the top shell 6. A buckle 12 is also fixedly installed on the top shell 6 between the two wire grooves 9.

[0022] like Figures 2-5As shown, the bottom shell 5 and the top shell 6 are fixedly connected to each other and fixedly installed at one end of the lamp panel body 1. The top shell 6 has shaft holes 13 on both sides. The cooperation between the top shell 6 and the pressure cover 7 provides conditions for fixing one end of the cable. The shaft holes 13 provide conditions for connecting the pressure cover 7 and the top shell 6. A retaining groove 18 is provided inside the pressure cover 7 located between the two wire grooves 9. Two side blocks 14 are fixedly installed at the lower end of the pressure cover 7. A rotating shaft 15 is fixedly installed on one side of each of the two side blocks 14, and the rotating shaft 15 is rotatably installed in the corresponding shaft hole 13. That is, the pressure cover 7 is rotatably installed on the top shell 6 through the two sets of side blocks 14 and rotating shafts 15. Two arc-shaped pressure plates 10 are fixedly installed inside the mounting groove 8. Each of the two arc-shaped pressure plates 10 has a bent groove on one side. The two metal arc-shaped pressure plates 10 facilitate applying pressure to one end of the cable. This ensures that one end of the cable is always electrically connected to one of the contacts 3. A T-shaped groove 16 is provided inside the wire groove 9. A T-shaped slider 19 is fixedly installed on the arc-shaped pressure block 11. The T-shaped slider 19 is slidably connected in one of the T-shaped grooves 16. A compression spring 17 is also installed in the T-shaped groove 16. One side of the compression spring 17 abuts against one side of the T-shaped groove 16, and the other side of the compression spring 17 abuts against one side of the T-shaped slider 19. By installing the arc-shaped pressure block 11 in the wire groove 9 through the T-shaped slider 19, when the arc-shaped pressure block 11 is dragged by the cable, the arc-shaped pressure block 11 drives the T-shaped slider 19 to slide in the obliquely opened T-shaped groove 16. This reduces the distance between the arc-shaped pressure block 11 and the cable by utilizing the height difference, thereby gradually increasing the pressure applied to the cable and preventing one end of the cable from detaching from the contact 3.

[0023] It should be noted that this utility model is an LED light-emitting module to prevent poor contact. When connecting multiple contacts 3 at one end of the lamp board body 1 to cables, one end of multiple cables can be placed in the two wire grooves 9 on the top shell 6. Then, the wire core at one end of the cable is placed on the contact 3. Subsequently, the pressure cover 7 is rotated on the top shell 6 around the two rotating shafts 15, so that the pressure cover 7 drives the two arc-shaped pressure plates 10 to gradually rotate and press on the wire core, thus applying pressure to the wire core. As a result, the contact 3 and the wire core are in close contact and electrically connected. At this time, the mounting groove 8 in the pressure cover 7 is inserted into the buckle 12, and the inclined protrusion on one side of the buckle 12 is placed on the pressure cover. 7. The top shell 6 and the pressure cover 7 can be connected in a limiting manner. The two wire grooves 9 on one side of the pressure cover 7 are inserted above the cable. The two arc-shaped pressure blocks 11 on the side away from the T-shaped slider 19 abut against and apply a certain pressure to the cable, thereby reinforcing the installation of the cable. When the cable is pulled by an external force, the cable will synchronously drive the arc-shaped pressure block 11 to move to one side. Then, the arc-shaped pressure block 11 drives the T-shaped slider 19 to slide in the T-shaped groove 16. Since the T-shaped groove 16 is opened at an angle, when the T-shaped slider 19 gradually moves to a lower position in the T-shaped groove 16, the arc-shaped pressure block 11 will increase the pressure on the cable, thereby preventing the cable from detaching.
