Description

Technical Field

[0001] This application relates to the technical field of printed circuit board interconnection, and particularly to a printed circuit board connector and a printed circuit board connection structure. Background Art

[0002] In modern electronic and electrical equipment, there are many types of board connectors and connection forms for printed circuit boards (PCBs) according to different requirements. Currently, the three most widely used and basic types are as follows: First, directly use commercial terminal blocks soldered on their respective printed circuit boards (PCBs), and use commercial connectors of a certain length to form inter-board interconnection; second, use several soft wires, press terminals at the wire joints, and then insert the terminals into the terminal blocks of the printed circuit board (PCB) to form inter-board interconnection; third, use FPC (flexible printed circuit board) for inter-board interconnection.

[0003] For the first solution, it is difficult to find commercial connectors of the appropriate length and they need to be customized, resulting in a relatively large cost investment. For the second solution, although the length of the soft wire can be set and it can solve some problems of the first solution, if the distance between the boards is too small, it will be difficult to press the terminals due to the too short soft wire, otherwise bending is required, causing unnecessary space waste. For the third solution, it has high requirements for process accuracy and often needs to be customized, and also has high requirements for space. Moreover, the above three solutions cannot play the role of minimizing the loop required for electromagnetic compatibility, and can hardly play the role of shielding interference. Summary of the Invention

[0004] Based on this, it is necessary to provide a printed circuit board connector and a printed circuit board connection structure that can play the role of minimizing the loop required for electromagnetic compatibility, can also play the role of shielding interference, have a simple structure, have relatively low requirements for process and space, have a wide application range, greatly reduce the production cost, do not require terminal pressing, and effectively avoid the phenomenon of space waste caused by bending the soft wire.

[0005] A printed circuit board connector includes:

[0006] A printed transfer board, on two opposite surfaces of the printed transfer board, there are provided a plurality of copper-clad areas, the plurality of copper-clad areas are arranged at intervals along a first direction on the printed transfer board, and the plurality of copper-clad areas penetrate through the printed transfer board along a second direction, and welding parts are respectively formed at two opposite ends of the copper-clad areas;

[0007] A pin assembly, the pin assembly includes a plurality of double-row pins arranged along the first direction, at least one of the double-row pins is used for corresponding connection with one of the copper-clad areas, the plurality of double-row pins are respectively soldered to the welding parts of the corresponding copper-clad areas, and the printed transfer board is located between the double-row pins.

[0008] In the above solution, a number of copper plating areas are provided on both opposite sides of the printed circuit board, so that two opposite sides of the printed circuit board form two electrodes, which is equivalent to a capacitor. To a certain extent, it can filter out external interference and reduce its destructive effect on useful signals. Moreover, the forward flow and reverse return of high-frequency signals are both located on the two opposite sides of the printed circuit board, greatly reducing the loop area and reducing the spillage of high-frequency signals, which is beneficial to electromagnetic compatibility. By arranging a number of copper plating areas on the printed circuit board at intervals in the first direction, it effectively avoids the contact between adjacent two copper plating areas, thus preventing the occurrence of short-circuit phenomena. By providing double-row pins, one copper plating area can transmit one signal. One double-row pin can be correspondingly arranged with one copper plating area, or multiple double-row pins can be correspondingly arranged with one copper plating area. The same signal can be applied to multiple double-row pins, which can effectively avoid the problem of signal disconnection caused by the damage of one of the multiple double-row pins. The structure of this application is simple, with relatively low requirements for process and space, wide application range, greatly reducing production costs, and without the need for terminal pressing, effectively avoiding the phenomenon of space waste caused by bending the flexible wire.

[0009] In one embodiment, the surface of the copper plating area is subjected to immersion gold treatment.

[0010] By performing immersion gold treatment on the surface of the copper plating area, the copper plating area can be made wider and thinner with a larger surface area, which is beneficial to the heat dissipation of power signals.

[0011] In one embodiment, at least one of the copper plating areas is connected to two or more of the double-row pins. The same signal can be applied to two or more double-row pins, which can effectively avoid the problem of signal disconnection caused by the damage of one of the two or more double-row pins.

[0012] In one embodiment, the printed circuit board connector further includes a solder mask strip provided on the printed circuit board. The solder mask strip extends along the first direction, and the first direction is perpendicular to the second direction. By providing the solder mask strip, it can prevent excessive overflow of solder during the soldering of double-row copper pins.

[0013] In one embodiment, two solder mask strips are respectively provided on the same surface of the printed circuit board. Both of the two solder mask strips are located between the two welding parts, and the solder mask strip is arranged close to the double-row pins.

[0014] In one embodiment, two anti-misinsertion portions are provided at both opposite ends of the printed circuit board adapter. Both of the anti-misinsertion portions protrude from the printed circuit board adapter, and the two anti-misinsertion portions are respectively located on both sides of the pin assembly. By providing the anti-misinsertion portions, while facilitating insertion and extraction, lateral displacement and misinsertion can also be avoided.

[0015] In one embodiment, the double-row pins have a first end and a second end which are oppositely arranged. The first end is soldered to the copper plating area, and the second end extends out of the printed circuit board adapter.

[0016] In one embodiment, the horizontal height of the plane where the second end of the double-row pins is located is higher than the horizontal height of the plane where the end of the anti-misinsertion portion away from the printed circuit board adapter is located.

[0017] In one embodiment, the printed circuit board connector further includes at least one of the following features;

[0018] The thickness of the printed circuit board adapter is 0.6 mm to 0.8 mm;

[0019] The distance between two adjacent copper plating areas is 0.5 mm;

[0020] The distance between the central axes of two adjacent double-row pins is 1.27 mm to 2.54 mm.

[0021] The distance between two adjacent copper plating areas being 0.5 mm can avoid short circuits between two adjacent copper plating areas and also make the overall structure more compact. By setting the distance between the central axes of two adjacent double-row pins to be 1.27 mm to 2.54 mm, the overall structure can be made more compact, minimizing the overall size and making the overall structure flattened, so that the space occupancy rate of the present application is small.

[0022] The present application also provides a printed circuit board connection structure, including the printed circuit board connector as described above and a printed circuit board corresponding to the multiple double-row pins of the printed circuit board connector.

[0023] In one embodiment, the printed circuit board further includes a first printed circuit board and a second printed circuit board. A plurality of double-row sockets are provided on both the first printed circuit board and the second printed circuit board. The plurality of double-row sockets are arranged corresponding to the multiple double-row pins of the printed circuit board connector. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0040] Please refer to Figure 1 、 Figure 2 and Figure 3 , an embodiment of the present application relates to a printed circuit board connector 10, including a printed adapter board 100 and a pin assembly, and the pin assembly is welded to the printed adapter board 100.

[0041] Please refer to Figure 1 、 Figure 3 and Figure 4 , both opposite sides of the printed adapter board 100 are provided with a plurality of copper plating areas 110. The plurality of copper plating areas 110 are arranged at intervals in the first direction on the printed adapter board 100, and the plurality of copper plating areas 110 all penetrate the printed adapter board 100 in the second direction. The first direction is perpendicular to the second direction. By arranging the plurality of copper plating areas 110 at intervals in the first direction on the printed adapter board 100, it is possible to effectively prevent adjacent two copper plating areas 110 from contacting, thereby avoiding the phenomenon of short circuit.

[0042] Specifically, the printed adapter board 100 has a front side and a back side which are opposite to each other, and a plurality of copper plating areas 110 are provided on both the front side and the back side. The first direction is the X direction. The second direction is the Y direction. It should be understood that: the copper plating area 110 can be used as a signal line for transmitting signals. The number of copper plating areas 110 is not limited in this application and can be set according to the usage requirements, and the width of each copper plating area 110 can be set according to the magnitude of the signal current. In this embodiment, the number of copper plating areas 110 is six. In other embodiments, the number of copper plating areas 110 is four, five, seven, eight or more.

[0043] The front side and the back side of the printed adapter board 100 form two electrodes, which is equivalent to a capacitor, and can filter out external interference to a certain extent and reduce its destructive effect on useful signals. The forward flow and reverse return of high-frequency signals are both located on the front side and the back side of the printed adapter board 100, greatly reducing the loop area and reducing the spillage of high-frequency signals, which is beneficial to electromagnetic compatibility.

[0044] Welding portions 111 are respectively formed at two opposite ends of the copper plating area 110. Specifically, the copper plating area 110 has a third end and a fourth end that are opposite to each other in the second direction, and the welding portions 111 are respectively located at the third end and the fourth end of the copper plating area 110.

[0045] Please refer to Figure 1 and Figure 2 , the pin assembly includes a plurality of double-row pins 200 arranged along the first direction. At least one double-row pin 200 is used for corresponding connection with a copper plating area 110. The plurality of double-row pins 200 are respectively welded to the welding portions 111 of the corresponding copper plating areas 110, and the printed circuit board adapter 100 is located between the double-row pins 200. A copper plating area 110 can transmit one signal. One double-row pin 200 can be correspondingly arranged with a copper plating area 110, or multiple double-row pins 200 can be correspondingly arranged with a copper plating area 110. The same signal can be applied to multiple double-row pins 200, which can effectively avoid the problem of signal disconnection caused by the damage of one of the multiple double-row pins 200.

[0046] Welding portions 111 are provided on both the front and back of the printed circuit board adapter 100. One row of the double-row pins 200 is welded to the welding portion 111 on the front of the printed circuit board adapter 100. The other row of the double-row pins 200 is welded to the welding portion 111 on the back of the printed circuit board adapter 100.

[0047] Specifically, the pins 220 of the double-row pins 200 are straight pins 220. It should be understood that: the length of the pins 220 of the double-row pins 200 is set according to the use requirements, which can ensure that the pins 220 of the double-row pins 200 can withstand a large force during insertion and extraction, and the pins 220 will not be bent due to the excessive length of the pins 220.

[0048] The printed circuit board connector 10 of the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0049] Another disadvantage of the first solution mentioned in the background art using the connector solution is that its cross-sectional area for passing current is too small to pass a large current and cannot play a role in heat dissipation. For the second solution, due to the factor of the soft wire insulation skin, heat dissipation is even more impossible. To solve the above problems, the present application adopts the following technical solutions:

[0050] Please refer to Figure 1 , Figure 2 and Figure 3, an immersion gold treatment is performed on the surface of the copper plating area 110. Immersion gold uses a chemical deposition method to produce a plating layer through a chemical oxidation-reduction reaction. Generally, the thickness is relatively thick. It is one of the methods for depositing the chemical nickel-gold gold layer and can achieve a relatively thick gold layer. The immersion gold process deposits a stable color, good brightness, flat plating layer, and good solderability on the surface of the copper plating area 110.

[0051] By performing an immersion gold treatment on the surface of the copper plating area 110, the copper plating area 110 can be made wider and thinner with a larger surface area, which is beneficial to the heat dissipation of power signals.

[0052] Please refer to Figure 1 、 Figure 2 and Figure 3 , according to some embodiments of the present application, optionally, in one embodiment, two double-row pins 200 are provided on a copper plating area 110. It should be noted that: a copper plating area 110 can transmit one signal. Therefore, the same signal can be applied to the two double-row pins 200, which can effectively avoid the problem of signal disconnection caused by the damage of one of the two double-row pins 200.

[0053] In other embodiments, three double-row pins 200, four double-row pins 200, or even more double-row pins 200 are provided on a copper plating area 110.

[0054] In this embodiment, the number of copper plating areas 110 is six, which are the first copper plating area 110, the second copper plating area 110, the third copper plating area 110, the fourth copper plating area 110, the fifth copper plating area 110, and the sixth copper plating area 110 along the first direction. Among them, two double-row pins 200 are provided on the first copper plating area 110, the second copper plating area 110, the fifth copper plating area 110, and the sixth copper plating area 110. One double-row pin 200 is provided on the third copper plating area 110 and the fourth copper plating area 110.

[0055] Please refer to Figure 2 、 Figure 3 and Figure 4 , according to some embodiments of the present application, optionally, the printed circuit board connector 10 further includes a solder mask tape 300 provided on the printed circuit adapter board 100, and the solder mask tape 300 extends along the first direction.

[0056] Two solder mask tapes 300 are respectively provided on the same surface of the printed circuit adapter board 100. Both solder mask tapes 300 are located between the two welding parts 111, and the solder mask tape 300 is provided close to the double-row pins 200. Specifically, the copper plating area 110 has an un-soldered area formed between the two welding parts 111, and the two solder mask tapes 300 are respectively provided between the un-soldered area and the two welding parts 111. By providing the solder mask tape 300, it can be avoided that the solder overflows excessively to the un-soldered area during the welding of the double-row copper pins.

[0057] Please refer to Figure 1 、 Figure 2 and Figure 3 , according to some embodiments of the present application, optionally, two anti-misinsertion portions 400 are provided at both opposite ends of the printed circuit board 100. The two anti-misinsertion portions 400 protrude from the printed circuit board 100, and the two anti-misinsertion portions 400 are respectively located on both sides of the pin assembly.

[0058] Specifically, an insertion area is formed between the two anti-misinsertion portions 400 at the same end of the printed circuit board 100. The pin assembly is located in the insertion area, which can facilitate insertion and extraction while avoiding lateral displacement misinsertion.

[0059] Please refer to Figure 1 、 Figure 2 and Figure 4 , according to some embodiments of the present application, optionally, the double-row pins 200 have a first end and a second end that are oppositely arranged. The first end is welded to the copper-clad area 110, and the second end protrudes from the printed circuit board 100. Specifically, the double-row pins 200 include a mounting base 210 and two rows of pins 220 that are spaced apart on the mounting base 210, and the two rows of pins 220 are insulated. The mounting base 210 can be in contact with the printed circuit board 100. More specifically, the mounting base 210 is made of an insulating material.

[0060] The first end of the row of pins 220 is located below the mounting base 210, and the second end of the row of pins 220 is located above the mounting base 210. The row of pins 220 has a first section located below the mounting base 210 and a second section located above the mounting base 210, and the length of the first section is less than the length of the second section.

[0061] Please refer to Figure 1 and Figure 2 , according to some embodiments of the present application, optionally, the horizontal height of the plane where the second end of the double-row pins 200 is located is higher than the horizontal height of the plane where the end of the anti-misinsertion portion 400 away from the printed circuit board 100 is located, so as not to affect the insertion and extraction of the double-row pins 200.

[0062] Please refer to Figure 1 、 Figure 2 and Figure 3 , according to some embodiments of the present application, optionally, the thickness of the printed circuit board 100 is 0.6 mm to 0.8 mm. The smaller the thickness of the printed circuit board 100, the more obvious its capacitance effect, and the more beneficial it is to signal anti-interference. It should be noted that: the present application does not limit the thickness and length of the printed circuit board 100. The thickness of the printed circuit board 100 can be selected between 0.6 mm and 0.8 mm, and the length of the printed circuit board 100 is set according to actual needs. Exemplarily, the thickness of the printed circuit board 100 is 0.7 mm.

[0063] The distance between two adjacent copper - clad areas 110 is 0.5 mm. This can avoid short - circuits between two adjacent copper - clad areas 110 and also make the overall structure more compact.

[0064] Please refer to Figure 1 、 Figure 2 and Figure 3 According to some embodiments of the present application, optionally, the distance between the central axes of two adjacent double - row pins 200 is 1.27 mm to 2.54 mm. It should be noted that: the present application does not limit the distance between the central axes of two adjacent double - row pins 200, and the distance between the central axes of two adjacent double - row pins 200 can be selected between 1.27 mm and 2.54 mm. Exemplarily, the distance between the central axes of two adjacent double - row pins 200 is 2 mm.

[0065] By setting the distance between the central axes of two adjacent double - row pins 200 to be 1.27 mm to 2.54 mm, the overall structure can be made more compact, minimizing the overall size and making it flatter, so that the space occupancy rate of the present application is smaller.

[0066] Please refer to Figure 1 、 Figure 2 and Figure 5 The present application also provides a printed circuit board connection structure 20, including the printed circuit board connector 10 as described above and a printed circuit board corresponding to the multiple double - row pins 200 of the printed circuit board connector 10.

[0067] The printed circuit board includes a first printed circuit board 500 and a second printed circuit board 600, and the printed circuit board connector 10 is connected between the first printed circuit board 500 and the second printed circuit board 600. In this embodiment, the first printed circuit board 500 and the second printed circuit board 600 are respectively vertically connected to the printed circuit board connector 10.

[0068] Both the first printed circuit board 500 and the second printed circuit board 600 are provided with multiple double - row sockets 610, and the multiple double - row sockets 610 are correspondingly arranged with the multiple double - row pins 200 of the printed circuit board connector 10. Jacks corresponding to the double - row pins 200 are opened on the double - row sockets 610. After all the double - row pins 200 are inserted into the corresponding double - row sockets 610, the printed circuit board connector 10 can realize the interconnection between the first printed circuit board 500 and the second printed circuit board 600.

[0069] Example:

[0070] In the magnetic levitation artificial heart device, to minimize the number of cables and reduce the difficulty of process implementation, the above-mentioned printed circuit board connection structure 20 can be adopted. The coil lead-out wire of the artificial heart device can be connected to one of the first printed board 500 and the second printed board 600, and one of the first printed board 500 and the second printed board 600 is connected to the other of the first printed board 500 and the second printed board 600 through the printed circuit board connector 10. The printed circuit board connector 10 can realize the interconnection between the first printed board 500 and the second printed board 600. Power signals and other signals can be transmitted between the first printed board 500, the printed circuit board connector 10 and the second printed board 600.

[0071] The coil lead-out wire needs to carry a high-frequency alternating large current of up to 3A, and the conventional cable or long copper needle solutions are not suitable for the flow of such a large current. This alternating current will generate a large amount of electromagnetic interference in space. At the same time, there are also weak analog signals that need to reach the detection and control board from the signal board. In this narrow space, it is necessary to ensure that the electromagnetic interference can neither interfere with the internal circuit nor radiate to the outside of the device, causing malfunctions in other devices. Therefore, the printed circuit board connector 10 in this application can greatly reduce the above risks.

[0072] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0073] The above-described embodiments only represent several implementation manners of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application should be subject to the appended claims.
