Description

Technical Field

[0001] This utility model relates to a circuit board, specifically a metallized half-hole circuit board that is easy to manufacture and install, and belongs to the field of circuit board technology. Background Technology

[0002] A circuit board, also known as a printed circuit board or printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Before the advent of circuit boards, the interconnection between electronic components was achieved by directly connecting them with wires. Nowadays, wires are only used for experimental applications in laboratories, while circuit boards have gained absolute control in the electronics industry.

[0003] A utility model patent with authorization announcement number "CN222339650U" entitled "High-efficiency circuit board with metallized half-hole" proposes a circuit board with high production efficiency. However, in order to install the half-hole copper sleeve, multiple positioning holes need to be opened on the circuit board body, and locking holes also need to be opened on the half-hole copper sleeve. In order for the locking rod to pass through the positioning holes and locking holes at the same time, it is necessary to ensure that the positions of the positioning holes and locking holes cannot be deviated during the opening process. When the position is slightly deviated, the installation cannot be completed, resulting in poor stability in use. Moreover, opening multiple positioning holes and locking holes will also increase the production steps, thereby reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a metallized half-hole circuit board that is easy to manufacture and install in order to solve the above problems. This avoids the need to open multiple holes to install the half-hole copper sleeve, thereby simplifying the manufacturing and installation steps and improving the efficiency of manufacturing and installation.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a metallized semi-hole circuit board that is easy to manufacture and install, comprising a circuit board body, a plurality of semi-hole copper sleeves being engaged on one side of the circuit board body, two auxiliary mounting strips being fixedly connected to one end of the plurality of semi-hole copper sleeves, the auxiliary mounting strips abutting against the circuit board body, the auxiliary mounting strips being provided with a plurality of positioning grooves, the two ends of the semi-hole copper sleeves being respectively located inside the two positioning grooves on the two auxiliary mounting strips and being fixedly connected to the auxiliary mounting strips, a connecting frame being engaged on the circuit board body, one side of the connecting frame abutting against the two auxiliary mounting strips, the connecting frame being provided with a limiting structure, the limiting structure including a locking block and a connecting shaft, two locking blocks being slidably connected to the connecting frame, two connecting shafts being fixedly connected to the locking blocks, the connecting shafts being slidably connected to the connecting frame, two locking slots being provided on both sides of the circuit board body, the locking blocks engaging with the adjacent locking slots, and a spring being sleeved on the outside of the connecting shaft.

[0006] Preferably, the cross-section of the auxiliary mounting strip is a rounded wedge shape, and the multiple positioning grooves on the auxiliary mounting strip are linearly and equidistantly distributed.

[0007] Preferably, the cross-section of one end of the card block is trapezoidal, and the cross-section of the other end of the card block is T-shaped.

[0008] Preferably, the inner side of the cross-section at one end of the connecting frame has a trapezoidal structure, and the cross-section at one end of the connecting shaft has a T-shaped structure.

[0009] Preferably, one end of the spring abuts against the connecting shaft, and the other end of the spring abuts against the connecting frame.

[0010] Preferably, a plurality of spacers are fixedly connected to the connecting frame, and the inner side of the spacers abuts against the circuit board body.

[0011] Preferably, multiple conductive blocks are fixedly connected to both sides of the circuit board body, and the two ends of the semi-hole copper sleeve respectively abut against two adjacent conductive blocks.

[0012] The beneficial effects of this utility model are as follows: The two ends of multiple semi-hole copper sleeves can be respectively located inside the positioning grooves on two auxiliary mounting strips and fixedly connected to the auxiliary mounting strips. The positioning grooves can position the auxiliary mounting strips and the semi-hole copper sleeves, thereby ensuring that the distance between two adjacent semi-hole copper sleeves is equal, facilitating smooth engagement between the semi-hole copper sleeves and the circuit board body. Then, multiple semi-hole copper sleeves can be moved to engage with one side of the circuit board body. Next, the connecting frame can be moved to fit over the semi-hole copper sleeves. Finally, the connecting frame is moved towards the auxiliary mounting strip. When the connecting frame and the auxiliary mounting strip come into contact, all four springs will contract simultaneously. The contraction of two springs will cause the locking blocks at one end to move toward the slots and engage with them. Therefore, when the connecting frame and the auxiliary mounting strip come into contact, the two locking blocks will engage with the two slots respectively. At this time, the connecting frame will not be able to move. Since one side of the connecting frame blocks the auxiliary mounting strip, the auxiliary mounting strip and the half-hole copper sleeve will also not be able to move, thus realizing the installation of the half-hole copper sleeve. Since it is not necessary to open multiple holes to install the half-hole copper sleeve, the production steps are simplified and the production efficiency is improved. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a metallized half-hole circuit board for easy production and installation includes a circuit board body 1. Multiple half-hole copper sleeves 4 are engaged on one side of the circuit board body 1. Two auxiliary mounting strips 2 are fixedly connected to one end of each half-hole copper sleeve 4. The auxiliary mounting strips 2 abut against the circuit board body 1. Each auxiliary mounting strip 2 has multiple positioning grooves 3. The two ends of each half-hole copper sleeve 4 are located inside the two positioning grooves 3 on the two auxiliary mounting strips 2 and are fixedly connected to them. A connecting frame 5 is engaged on the circuit board body 1. One side of the connecting frame 5 abuts against two auxiliary mounting strips 2. The connecting frame 5 is provided with a limiting structure 7, which includes a locking block 701 and a connecting shaft 702. Two locking blocks 701 are slidably connected to the connecting frame 5, and two connecting shafts 702 are fixedly connected to the locking blocks 701. The connecting shafts 702 are slidably connected to the connecting frame 5. Two slots 704 are provided on both sides of the circuit board body 1. The locking blocks 701 engage with the adjacent slots 704. A spring 703 is sleeved on the outside of the connecting shaft 702.

[0023] As a technical optimization solution of this utility model, such as Figure 5 As shown, the cross-section of the auxiliary mounting strip 2 is a rounded wedge-shaped structure, and the multiple positioning grooves 3 located on the auxiliary mounting strip 2 are linearly and equidistantly distributed, thus playing a guiding role when the auxiliary mounting strip 2 moves toward the circuit board body 1.

[0024] As a technical optimization solution of this utility model, such as Figure 6 As shown, the cross-section of one end of the card block 701 is trapezoidal, and the cross-section of the other end of the card block 701 is T-shaped, thus it can play a guiding role when the card block 701 and the card slot 704 are engaged.

[0025] As a technical optimization solution of this utility model, such as Figure 5 and Figure 6 As shown, the inner side of the cross-section of one end of the connecting frame 5 has a trapezoidal structure, and the cross-section of one end of the connecting shaft 702 has a T-shaped structure. Therefore, it can play a guiding role in the process of the connecting frame 5 moving towards the circuit board body 1.

[0026] As a technical optimization solution of this utility model, such as Figure 2 As shown, one end of the spring 703 abuts against the connecting shaft 702, and the other end of the spring 703 abuts against the connecting frame 5. Therefore, the locking block 701 and the locking groove 704 can be engaged under the action of the spring 703.

[0027] As a technical optimization solution of this utility model, such as Figure 1 , Figure 3 and Figure 4As shown, multiple spacers 6 are fixedly connected to the connecting frame 5. The inner side of the spacer 6 abuts against the circuit board body 1, so the spacers 6 can block the two adjacent half-hole copper sleeves 4, thereby avoiding short circuits.

[0028] As a technical optimization solution of this utility model, such as Figure 3 and Figure 4 As shown, multiple conductive blocks 8 are fixedly connected to both sides of the circuit board body 1. The two ends of the semi-hole copper sleeve 4 are respectively in contact with two adjacent conductive blocks 8, so that conductivity can be achieved through the contact between the semi-hole copper sleeve 4 and the conductive blocks 8.

[0029] In use, the two ends of the multiple semi-hole copper sleeves 4 can be located inside the positioning grooves 3 on the two auxiliary mounting strips 2 and fixedly connected to the auxiliary mounting strips 2. The positioning grooves 3 can position the auxiliary mounting strips 2 and the semi-hole copper sleeves 4, thereby ensuring that the distance between two adjacent semi-hole copper sleeves 4 is equal, which facilitates the smooth engagement of the semi-hole copper sleeves 4 with the circuit board body 1. Then, the multiple semi-hole copper sleeves 4 can be moved to engage with one side of the circuit board body 1. Then, the connecting frame 5 is moved to fit over the outside of the semi-hole copper sleeves 4. Next, the connecting frame 5 is moved toward the auxiliary mounting strip 2. When the connecting frame 5 is aligned with the auxiliary mounting strip 2, the semi-hole copper sleeves 4 are engaged with the circuit board body 1. When the two springs 703 come into contact with each other, they will contract simultaneously. The contraction of two springs 703 will drive the locking block 701 at one end to move toward the locking groove 704 and engage with the locking groove 704. Therefore, when the connecting frame 5 and the auxiliary mounting strip 2 come into contact, the two locking blocks 701 will engage with the two locking grooves 704 respectively. At this time, the connecting frame 5 will not be able to move. Since one side of the connecting frame 5 blocks the auxiliary mounting strip 2, the auxiliary mounting strip 2 and the half-hole copper sleeve 4 will also not be able to move, thus realizing the installation of the half-hole copper sleeve 4. Since it is not necessary to open multiple holes to realize the installation of the half-hole copper sleeve 4, the production steps are simplified and the production efficiency is improved.
