[0040] Embodiment 1 of the utility model anti-drop assembly

[0041] like Figure 1 and Figure 2 As shown, the anti-detachment component provided by the utility model includes: a plurality of embedded installation grooves 2 opened on the circuit board body, each embedded installation groove 2 is provided with a soldering pad, and the soldering pad is connected to the electronic component body 4, the top of the electronic component body 4 is lower than the top of the circuit board body, such a configuration enables the electronic component body 4 to be protected in the embedded installation groove 2, can reduce the situation where the electronic component is subjected to external force during use, and thus reduce the situation where the electronic component is detached. For ease of understanding, the circuit board body is represented by D and marked in the drawings.

[0042] Further, such as Figure 1 and Figure 2 As shown, the pad is connected with solder paste 3, and the pad is connected with the electronic component body 4 through the solder paste 3, and the electronic component body 4 and the pad can be soldered together through the solder paste 3.

[0043] Embodiment 2 of the utility model anti-drop assembly

[0045] Further, such as Figure 1 and Figure 2 As shown, the fixing part is a reinforcing solder paste 5, which is connected between the outer surface of the electronic component body 4 and the inner wall of the embedded installation groove 2. By arranging the reinforcing solder paste 5 between the electronic component body 4 and the embedded installation groove 2, the electronic component body 4 can be further fixed, so that the installation of the electronic component body 4 is more stable and not easy to fall off;

[0046] Solder paste is a gray paste, also called solder paste. Solder paste is a new type of welding material that came into being with SMT. It is a paste mixture formed by mixing solder powder, flux and other surfactants, thixotropic agents, etc. It is mainly used for welding electronic components such as PCB surface resistors, capacitors, and ICs in the SMT industry. Solder paste must be cooled before it can be sintered, that is, it must go through reflow soldering. Reflow soldering is a heating furnace that can obtain the heat necessary for solder paste to assist in sintering of solder paste. After sintering, it can play the role of conducting parts.

[0047] Embodiment 3 of the anti-drop assembly of the utility model

[0048] like Figure 3-Figure 9 As shown, the PCB board provided by the utility model uses an anti-detachment component, and an installation protection mechanism 6 is arranged on the outside of the circuit board body. The installation protection mechanism 6 includes an installation protection frame 601 arranged on the outer surface of the circuit board body. A limiting portion is arranged on the installation protection frame 601, and the limiting portion is used to limit the circuit board body. A plurality of installation holes 612 are opened on the installation protection frame 601. The installation protection frame 601 can protect the circuit board body and reduce the situation where the circuit board body is damaged by bumps. The arrangement of the circuit board connecting seat 602 allows the installation protection frame 601 to be installed and fixed by bolts.

[0049] Further, such as Figure 3-Figure 6 As shown, the limiting portion includes an opening on one side of the top of the installation protection frame 601, in which a connecting shaft 603 is fixedly installed, and a circuit board connecting seat 602 is sleeved on the outer surface of the connecting shaft 603, and the bottom of the circuit board connecting seat 602 is arc-shaped. Such a setting can facilitate the rotation of the circuit board connecting seat 602, and the circuit board connecting seat 602 can be installed in the opening through the connecting shaft 603.

[0050] Further, such as Figure 3-Figure 6 As shown, the limiting portion also includes a slide groove opened on the other side of the top of the installation protection frame 601, and the limiting seat 606 is slidably connected in the slide groove. The limiting seat 606 can move in the slide groove. A notch 613 is also opened on one side of the top of the limiting seat 606. The setting of the notch 613 can facilitate the user to push the limiting seat 606.

[0051] Further, such as Figure 4As shown, a limiting slot 610 is provided on the side where the limiting seat 606 and the circuit board connecting seat 602 are close to each other, and a limiting plug plate 611 is inserted into the two limiting slots 610. The limiting plug plates 611 are fixedly installed on both sides of the circuit board body respectively. The circuit board body can be fixed by the cooperation of the limiting slot 610, the limiting plug plate 611, the limiting seat 606 and the circuit board connecting seat 602. After pushing the limiting seat 606 away from the circuit board body, the circuit board connecting seat 602 rotates around the connecting axis 603 so that the circuit board body can be tilted upward and taken out.

[0052] Further, such as Figure 7-Figure 8 As shown, both the limit seat 606 and the installation protection frame 601 are provided with a accommodating chamber 607, and a connecting rod 608 is inserted between the two accommodating chambers 607. The outer surface of the connecting rod 608 is provided with two limit springs 609 respectively located in the two accommodating chambers 607. The limit seat 606 and the installation protection frame 601 can be connected together through the cooperation between the accommodating chamber 607 and the connecting rod 608. The action force of the limit spring 609 can pull the limit seat 606 through the connecting rod 608 to improve the stability of the limit seat 606 when limiting the circuit board body.

[0053] Further, such as Fig. 9 As shown, circular grooves 604 with the connecting shaft 603 as the center are provided on both sides of the circuit board connecting seat 602, and the outer surface of the connecting shaft 603 is provided with a torsion spring 605 located in the circular groove 604, and the two ends of the torsion spring 605 are respectively fixedly connected to the connecting shaft 603 and the circular groove 604. When the limiting seat 606 is away from the circuit board body, the force of the torsion spring 605 can drive the circuit board connecting seat 602 to rotate, thereby causing the circuit board body to tilt upward, thereby facilitating the taking and placing of the circuit board body.

[0054] When in use, the circuit board connector 602 is fixed to the corresponding installation position in the vehicle body by passing the bolts through the installation holes 612. When the circuit board body needs to be removed, the limit seat 606 is pushed to separate the limit seat 606 from the circuit board body. At this time, the limit slot 610 on the limit seat 606 is separated from the corresponding limit plug plate 611, and the circuit board connector 602 rotates under the action of the torsion spring 605, so that the circuit board body is tilted upward, that is, Figure 6 As shown, the circuit board body can be removed by pulling the circuit board body so that the limiting slot 610 on the circuit board connection seat 602 is separated from the corresponding limiting plug plate 611;

[0055] During installation, insert the limiting plug plate 611 on one side of the circuit board body into the limiting slot 610 on the circuit board connecting seat 602, push the limiting seat 606 away from the circuit board connecting seat 602, press the circuit board body downward so that the circuit board body enters the installation protection frame 601, release the limiting seat 606, and the force of the limiting spring 609 drives the limiting seat 606 to contact the circuit board body, and the limiting slot 610 on the limiting seat 606 is plugged together with the corresponding limiting plug plate 611 to fix the circuit board body, so that the circuit board body is easy to disassemble and maintain after being installed in the vehicle body.
