[0057] Embodiment 1

[0058] This embodiment provides a mounting bracket for fixing a circuit board and an electronic component, thereby improving the shaking problem of the pins of the electronic component during welding with the circuit board and improving the welding quality between the electronic component and the circuit board.

[0059] The mounting bracket is used in a signal lamp, specifically, Figure 1 and Figure 2 As shown, the mounting bracket includes a bracket body 100, a positioning member 200 and a fixing structure 300. The positioning member 200 is arranged on the bracket body 100 and is located below the circuit board 10 in the signal lamp. The positioning member 200 is provided with a positioning hole 210, and the positioning hole 210 is arranged corresponding to the welding hole 11 on the circuit board 10. The fixing structure 300 is arranged on the bracket body 100, and the fixing structure 300 includes an installation space with adjustable size, and the installation space is used to accommodate the electronic component 20 led out of the circuit board 10. A pin 21 of the electronic component 20 extends out of the installation space and is passed through the positioning hole 210 and the welding hole 11 corresponding to the positioning hole 210.

[0060] The mounting bracket provided in this embodiment can fix the circuit board 10 and the electronic component 20 respectively through the positioning member 200 and the fixing structure 300 to prevent the circuit board 10 and the electronic component 20 from moving relative to each other, and the pin 21 of the electronic component 20 can be fixed through the positioning hole 210 on the positioning member 200 to prevent poor welding caused by the displacement of the pin 21 during the welding process between the pin 21 and the circuit board 10, thereby improving the welding quality between the circuit board 10 and the electronic component 20, and further improving the reliability of the circuit board 10 and the electronic component 20. In addition, by setting a mounting bracket to fix the circuit board 10 and the electronic component 20, the difficulty of welding is also reduced. In addition, the size of the installation space is adjustable, so that the mounting bracket can be applied to electronic components 20 of different sizes, and has high universality.

[0061] Optionally, in a possible embodiment, the electronic component 20 may be a resistor with a voltage-reducing function. Resistors with different resistance values ​​have different sizes, so the size of the installation space is adjustable so that the installation bracket can adapt to resistors of different sizes.

[0062] Optionally, continue to see Figure 1 and Figure 2 In this embodiment, the positioning member 200 is a positioning plate, and the positioning plate is supported below the circuit board 10. The positioning member 200 has a simple structure and is easy to process.

[0063] Further, see Figure 1 and Figure 2 , the installation space is spaced from the positioning member 200. Such a configuration can ensure the electrical gap between the electronic component 20 and the circuit board 10, which is beneficial to protecting the circuit board 10 and the electronic component 20, and can also avoid direct heat transfer between the electronic component 20 and the circuit board 10, so as to control the temperature rise of the circuit board 10, which is beneficial to protecting the circuit board 10.

[0064] Optionally, continue to see Figure 1 and Figure 2 The fixing structure 300 includes a first fixing plate 310 and a second fixing plate 320. The first fixing plate 310 is disposed on the bracket body 100 and close to the positioning member 200. The first fixing plate 310 is provided with a first notch 311, and the first notch 311 is used to accommodate a pin 21 of the electronic component 20. The second fixing plate 320 is disposed on the bracket body 100 and is used to be close to or away from the first fixing plate 310 to form an installation space with adjustable size. The electronic component 20 is disposed between the first fixing plate 310 and the second fixing plate 320. The second fixing plate 320 is provided with a second notch 321 corresponding to the first notch 311, and the second notch 321 is used to accommodate another pin 21 of the electronic component 20.

[0065] The method of fixing the electronic component 20 using the fixing structure 300 is as follows:

[0066] First, the second fixing plate 320 is moved away from the first fixing plate 310 to ensure that the distance between the first fixing plate 310 and the second fixing plate 320 is greater than the length of the electronic component 20;

[0067] Then, a pin 21 of the electronic component 20 is inserted into the positioning hole 210 and the welding hole 11;

[0068] Then, the main body of the electronic component 20 is placed between the first fixing plate 310 and the second fixing plate 320, and the pin 21 inserted into the positioning hole 210 is inserted into the first notch 311, and the other pin 21 of the electronic component 20 is inserted into the second notch 321;

[0069] Finally, the position of the second fixing plate 320 is adjusted so that the second fixing plate 320 and the first fixing plate 310 fix the electronic component 20 .

[0070] The fixing structure 300 is formed by the first fixing plate 310 and the second fixing plate 320 to fix the electronic component 20 . The structure is simple and the assembly of the electronic component 20 is convenient.

[0071] It can be understood that by adjusting the distance between the second fixing plate 320 and the first fixing plate 310 , the size of the installation space can be adjusted. The structure is simple, the adjustment is convenient, and the effect of fixing the electronic component 20 is better.

[0072] In this embodiment, the first fixing plate 310 is spaced apart from the positioning plate to ensure an electrical gap between the circuit board 10 and the electronic component 20. The distance between the first fixing plate 310 and the positioning plate can be set according to actual needs and is not specifically limited in this application.

[0073] Further, see Figure 2 In a possible embodiment, the first notch 311 may be trumpet-shaped, and a pin 21 of the electronic component 20 enters the first notch 311 from the end with a larger opening of the first notch 311. By setting the first notch 311 to be trumpet-shaped, the pin 21 of the electronic component 20 is easily assembled with the first notch 311.

[0074] In other embodiments, the first notch 311 may also include a flared portion 3211, an interference portion 3212 connected to the flared portion 3211, and a clamping portion 3213 connected to the interference portion 3212. When installing the pin 21 at the other end of the electronic component 20, the pin 21 is squeezed into the interference portion 3212 through the end with a larger opening of the flared portion 3211, and then the pin 21 is continuously pushed so that the pin 21 passes through the interference portion 3212 and enters the clamping portion 3213, thereby completing the assembly of the pin 21 and the second notch 321. The setting of the flared portion 3211 makes it less difficult for the pin 21 to squeeze into the interference portion 3212. The setting of the interference portion 3212 can prevent the pin 21 from coming out of the clamping portion 3213, thereby improving the connection reliability between the pin 21 and the second notch 321.

[0075] Optionally, in a possible embodiment, the second notch 321 may also be trumpet-shaped.

[0076] Optionally, continue to see Figure 2 In other possible embodiments, the second notch 321 may also include a flared portion 3211, an interference portion 3212 connected to the flared portion 3211, and a clamping portion 3213 connected to the interference portion 3212. When installing the pin 21 at the other end of the electronic component 20, the pin 21 is squeezed into the interference portion 3212 through the end with a larger opening of the flared portion 3211, and then the pin 21 is continuously pushed so that the pin 21 passes through the interference portion 3212 and enters the clamping portion 3213, thereby completing the assembly of the pin 21 and the second notch 321. The setting of the flared portion 3211 makes it less difficult for the pin 21 to squeeze into the interference portion 3212. The setting of the interference portion 3212 can prevent the pin 21 from coming out of the clamping portion 3213, thereby improving the connection reliability between the pin 21 and the second notch 321.

[0077] Furthermore, if Figure 3 and Figure 4 As shown, in this embodiment, the bracket body 100 includes a first column 110 and a second column 120. Among them, a positioning member 200 and a first fixing plate 310 are provided at one end of the first column 110. A second fixing plate 320 is provided at one end of the second column 120, and the other end of the second column 120 is slidably connected to the other end of the first column 110. An elastic member 400 is provided between the first column 110 and the second column 120, and one end of the elastic member 400 is connected to the first column 110, and the other end is connected to the second column 120.

[0078] The sliding connection between the first column 110 and the second column 120 and the cooperation of the elastic member 400 enable the distance of the second fixing plate 320 relative to the first fixing plate 310 to be adjustable, which has a simple structure and is easy to process and assemble the electronic component 20 .

[0079] It is worth noting that when the elastic member 400 is not subjected to external force, the distance between the first fixing plate 310 and the second fixing plate 320 should be greater than the length of the main part of the electronic component 20, so that when the electronic component 20 is installed between the first fixing plate 310 and the second fixing plate 320, the elastic force of the elastic member 400 can clamp the electronic component 20.

[0080] Optionally, continue to see Figure 3 and Figure 4 , the other end of the first column 110 is provided with a first connection hole 111, and the other end of the second column 120 is provided with a second connection hole 121. In order to achieve the sliding connection between the first column 110 and the second column 120, the other end of the first column 110 can be set to be slidably connected to the second connection hole 121; or the other end of the second column 120 can be set to be slidably connected to the first connection hole 111. In addition, a first connection frame 112 is provided in the first connection hole 111, and a second connection frame 122 is provided in the second connection hole 121. One end of the elastic member 400 is connected to the first connection frame 112, and the other end is connected to the second connection frame 122. The elastic member 400 is connected to the first column 110 and the second column 120 through the first connection frame 112 and the second connection frame 122, and the structure is simple and easy to assemble.

[0081] It is understandable that the elastic member 400 may be, but is not limited to, a tension spring.

[0082] Further, see Figure 3 and Figure 4 , a first card slot 1122 may be provided on the first connecting frame 112, and one end of the elastic member 400 may be hung on the first connecting frame 112 by means of the first card slot 1122 being engaged with one end of the elastic member 400, so that the connection reliability between the elastic member 400 and the first connecting frame 112 is better. Of course, a second card slot 1222 may also be provided on the second connecting frame 122, and the other end of the elastic member 400 may be hung on the second connecting frame 122 by means of the second card slot 1222 being engaged with the other end of the elastic member 400, so that the connection reliability between the elastic member 400 and the second connecting frame 122 is better.

[0083] Optionally, a first guiding slope 1121 may be provided on the first connecting frame 112, and the first guiding slope 1121 is inclined in the direction of the first card slot 1122. In this way, when one end of the elastic member 400 is inserted into the first card slot 1122, the first guiding slope 1121 can guide the one end of the elastic member 400 to enter the first card slot 1122, thereby reducing the difficulty of assembling the one end of the elastic member 400 and the first card slot 1122.

[0084] Of course, a second guiding slope 1221 may also be provided on the second connecting frame 122, and the second guiding slope 1221 is inclined in the direction of the second clamping groove 1222. In this way, when the other end of the elastic member 400 is clamped into the second clamping groove 1222, the second guiding slope 1221 can guide the other end of the elastic member 400 to enter the second clamping groove 1222, thereby reducing the difficulty of assembling the other end of the elastic member 400 and the second clamping groove 1222.

[0085] In this embodiment, two opposite sides of the first slot 1122 are provided with first guiding inclined surfaces 1121 , and two opposite sides of the second slot 1222 are provided with second guiding inclined surfaces 1221 .

[0086] Optionally, the first column 110 , the positioning member 200 and the first fixing plate 310 may be an integrated structure, which is convenient for processing and assembly. Similarly, the second column 120 and the second fixing plate 320 may also be an integrated structure.

[0087] Furthermore, the mounting bracket can fix multiple electronic components 20 at the same time to meet the signal light's installation requirements for multiple electronic components 20. Specifically, the first fixing plate 310 is provided with multiple first notches 311, and the multiple first notches 311 are arranged at intervals along the circumference of the first fixing plate 310. The second fixing plate 320 is provided with multiple second notches 321 along the circumference, and the second notches 321 are arranged one-to-one with the first notches 311. Each pair of the first notches 311 and the second notches 321 is used to fix one electronic component 20. Accordingly, the positioning member 200 is provided with positioning holes 210 corresponding one-to-one with the first notches 311.

[0088] In this embodiment, the first column 110 is disposed in the middle of the positioning member 200 and the first fixing plate 310, and the second column 120 is disposed in the middle of the second fixing plate 320. Such a configuration has a compact structure and is more beautiful.

[0089] Optionally, continue to see Figure 1 A monochrome signal light is generally provided with two electronic components 20. Therefore, for a one-way signal light, the first fixing plate 310 and the second fixing plate 320 may be rectangular, and the first fixing plate 310 is provided with two first notches 311, which are arranged at both ends of the length direction of the first fixing plate 310. Correspondingly, the second fixing plate 320 is provided with two second notches 321, which are arranged at both ends of the length direction of the second fixing plate 320.

[0090] like Figure 5 and Figure 6As shown, the two-color signal light is generally provided with three electronic components 20, so for the two-color signal light, the first fixing plate 310 and the second fixing plate 320 can be in a triangular shape, and the three sides of the triangular shape are arc sides convex toward the center. The three corners of the first fixing plate 310 are provided with first notches 311, and the three corners of the second fixing plate 320 are provided with second notches 321.

[0091] like Figure 7 and Figure 8 As shown, a three-color signal light is generally provided with four electronic components 20. Therefore, for a three-color signal light, the first fixing plate 310 and the second fixing plate 320 may be quadrilaterals, and the four sides of the quadrilateral are arc sides convex toward the center. The first fixing plate 310 is provided with first notches 311 at the four corners, and the second fixing plate 320 is provided with second notches 321 at the four corners.

[0092] Embodiment 2

[0093] This embodiment provides a mounting bracket, which is substantially the same in structure as the first embodiment, and is only improved on the basis of the first embodiment. Therefore, only the differences between the two are described here, and the same structures as the first embodiment are not described here. In this embodiment, the same or corresponding technical features as the first embodiment are marked with the same reference numerals.

[0094] Specifically, Figure 9-11 As shown, in this embodiment, the bracket body 100 is a connecting column 101, one end of the connecting column 101 is provided with a positioning member 200 and a first fixing plate 310, the other end of the connecting column 101 is provided with an external thread 1011, and a threaded hole 322 is provided on the second fixing plate 320, and the second fixing plate 320 is connected to the portion of the connecting column 101 provided with the external thread 1011 through the threaded hole 322. In this way, when the distance between the second fixing plate 320 and the first fixing plate 310 needs to be adjusted, it is only necessary to rotate the second fixing plate 320, which has a simple structure and is convenient for adjusting the position of the second fixing plate 320. In addition, the connection between the connecting column 101 and the second fixing plate 320 is achieved by threaded connection, which has better reliability.
