Description

Circuit board and circuit board assembly

The present invention relates to a circuit board and a circuit board assembly further including solder paste and wires.

Please refer to FIG. 5 to FIG. 7, when the wires 93 of the prior art circuit board 91 and other electronic devices 92 are hot-pressed and soldered (Hot Bar), the ends of the wires 93 are placed in the circuit respectively A plurality of conductive sheets 911 of the board 91 are coated with solder paste, and then heated (for example, through a reflow furnace) to melt the solder paste to connect the wires 93, and then the wires 93 are electrically connected to the conductive sheets 911.

In the foregoing process, in order to facilitate the bonding of the wire 93 to the position of the conductive sheet 911, the wire 93 is often pre-folded, and then the distance between the wires 93 is fixed with a clamp 94 so that the ends of the wires 93 The pitch of is approximately equal to the pitch of the conductive sheets 911. After the ends of the wires 93 are attached to the solder paste on the conductive sheet 911, the wire clip 94 is first removed and then heated.

However, the disadvantage of using the wire clamp 94 is that when the wire 93 is attached to the solder paste on the conductive sheet 911, the wire clamp 94 needs to maintain a certain distance (eg, 2 mm) from the edge of the circuit board 91, plus the wire clamp 94 itself has a certain The width (for example, 3 mm) causes a certain distance (at least 5 mm) between the electronic device 92 and the circuit board 91, and the electronic device 92 cannot be closer to the circuit board 91, which is not conducive to reducing the volume of the product.

In addition, the wire clip 94 itself requires a certain cost. In addition, although the wire clip 94 can be reused in theory, if the electronic device 92 is manufactured by another supplier, the wire clip 94 is often already installed on the wire 93 when the electronic device 92 is shipped from the factory, and the wire clip 94 is often removed It will not be returned to the supplier anymore, so the clamp 94 is actually a consumable item, which not only costs a certain amount of cost but is also environmentally friendly.

In addition, even if the wire clip 94 is installed, the wire clip 94 will be removed before heating, so it is still possible to move to the position of the wire 93 during the heating process, so in order to ensure that the end of the wire 93 can be held The base located below the conductive sheet 911 must be provided with a wire management jig to fix the position of the wire 93, and the wire management jig also requires a certain cost, and it takes a certain time to install the wire management jig.

Therefore, the circuit board in the prior art needs to be improved.

In view of the aforementioned shortcomings and deficiencies of the prior art, the present invention provides a circuit board and a circuit board assembly, which helps to keep the wires at a fixed distance without the use of wire clips and cable management jigs.

In order to achieve the above-mentioned creative purpose, the technical means adopted by the present invention is to design a circuit board for electrically connecting a plurality of conductors. The circuit board includes a board body and a plurality of conductive sheets. A plurality of wire grooves are recessed on one edge of the board body, and the wire grooves are used to accommodate the wires to limit the positions of the wires. The conductive pieces are arranged on the plate body, and the side edges of the wire grooves are recessed adjacent to the plate body, and the positions of the conductive pieces correspond to the positions of the wire grooves, respectively. The conductive sheets are respectively used to electrically connect the wires.

In order to achieve the above creation purpose, the present invention further provides a circuit board assembly, which includes a circuit board, a plurality of solder pastes and a plurality of wires. The circuit board includes a board body and a plurality of conductive sheets. A plurality of wire grooves are recessed on one edge of the board body. The conductive pieces are arranged on the plate body, and the side edges of the wire grooves are recessed adjacent to the plate body, and the positions of the conductive pieces correspond to the positions of the wire grooves, respectively. The solder pastes are respectively provided on the conductive sheets. The wires are respectively accommodated in the wire grooves of the circuit board and restricted by the wire grooves relative to the circuit board. The wires are electrically connected to the conductive sheets through the solder paste, respectively.

The advantage of the present invention lies in that, by providing a wire groove on the edge of the board body of the circuit board, the wire can be directly accommodated in the wire groove, so as to achieve the function of restricting the position of the wire. Therefore, the present invention can limit the wire without using a clamp, which can save the cost of the clamp and achieve the purpose of environmental protection. Moreover, the use of wire clips is eliminated, and the electronic device can be closer to the circuit board, which is conducive to reducing the volume of the product. Finally, during the heating process of the present invention, the wire groove also continues to play a limiting role, so there is no need to install the prior art cable management jig, and a certain cost and time for installing the cable management jig can be saved. The new model thus achieves the creative purpose of reducing volume, reducing cost and improving production efficiency.
