[0001] The present invention relates to the technical field of PCB board connectors, in particular to a PCB board connector and a PCB board connection structure. Background Art

[0002] In the existing PCB board power wiring process, the mother header is first soldered to the finished PCB circuit board through soldering. When wiring is required, the male header that is compatible with the mother header is plugged into the mother header to complete the power wiring process of the PCB board;

[0003] When the PCB board needs to install external wires, you need to first fix the busbars and solder them to the PCB board, and then plug the sub-busbar connectors into the busbars. After the busbars and sub-busbars are connected, they should be perpendicular to the PCB board. The two connectors of the busbars and sub-busbars cooperate with each other to achieve docking, so that the connection between the external wires and the PCB board can be successfully completed.

[0004] However, the two connectors such as the female header and the female header cooperate with each other and connect with the wires, which often form a relatively high height and occupy a large space in the vertical direction perpendicular to the surface of the PCB board. For some electrical instruments with small internal space and high space utilization requirements, the use of female headers and female headers for connection will interfere with the installation of other components and affect the installation of other components.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0042] See also Figures 1 to 7 The present invention provides a PCB board connector and a PCB board connection structure, and the technical solution is as follows:

[0043] A PCB connector includes: a housing 2, a first slide groove 11 is formed on the housing 2, and a plurality of through holes are formed in the first slide groove 11;

[0044] Also includes:

[0045] A wiring fixing mechanism is fixedly installed in the first slide groove 11 for performing a one-time fixed connection of the wire 6;

[0046] A locking mechanism is fixedly mounted on the housing 2 for achieving a fixed connection between the housing 2 and the PCB board.

[0047] When it is necessary to connect the lines of the PCB board 1, the person manually inserts the wire 6 to be connected into the first slide groove 11 through the through hole. When the person manually completely inserts the wire 6 to be connected into the first slide groove 11, the person manually rotates the wiring fixing structure located in the first slide groove 11, and the wiring fixing mechanism moves downward, pressing the wire interface to be connected onto the PCB board 1, so that the wire interface of the wire 6 is pressed onto the copper tin on the PCB board 1, and the wiring part of the wire 6 is fully conductive with the contact part on the PCB board 1. After the wiring is completed, the shell 2 is aligned with the wiring hole 3 on the PCB board and inserted into the wiring hole 3. The locking mechanism automatically locks the shell 2 onto the PCB board 1. In the above process, the connector is integrated into a whole. It is only necessary to insert the wire 6 to be connected into the first slide groove 11 of the shell 2, and then rotate the wiring fixing mechanism. The wiring operation can be completed without setting two wiring heads, thereby reducing the space occupancy of the connector.

[0048] As an embodiment of the present invention, refer to Figure 2 and Figure 3 , the wiring fixing mechanism includes:

[0049] A fixing block 19 is fixedly connected to the inner wall of the first chute 11, and a plurality of fixing blocks 19 are arranged at intervals along the inner wall of the first chute 11;

[0050] Square grooves 21, multiple fixed blocks 19 are provided with square grooves 21, and the inner walls of the multiple square grooves 21 are slidably mounted with the pressing plates 10;

[0051] Conductive blocks 12: Multiple conductive blocks 12 are fixedly mounted on the inner wall of the housing 2. The multiple conductive blocks 12 are spaced apart along the inner wall of the housing 2. Each conductive block 12 is located between two adjacent fixed blocks 19, and the multiple conductive blocks 12 are all located below the pressing plate 10.

[0052] The clamping screw 4 is threadedly connected to one top of the fixing block 19 , and the bottom of the clamping screw 4 is threadedly connected to the clamping plate 10 .

[0053] When the person manually inserts the wire 6 to be connected into the first slide groove 11, the exposed copper wire of the wire 6 is located below the clamping plate 10, and the person manually uses a screwdriver to rotate the clamping screw 4. Since the clamping plate 10 is threadedly connected to the clamping screw 4, when the fastening screw is rotated, the clamping plate 10 is pushed downward, and the clamping plate 10 moves downward along the inner side wall of the square groove 21. The clamping plate 10 continuously applies pressure in the direction of the conductive block 12, and the clamping plate 10 presses the conductive wire 6 tightly against the conductive block 12 and continuously pushes the conductive wire 6 downward. The conductive block 12 is made of a copper material with a certain degree of elasticity. The conductive block 12 is pushed downward by the pressing plate 10. When the housing is fixedly installed on the PCB board 1, the bottom wall of the conductive block 12 contacts the copper wire on the PCB board 1. The conductive block 12 is electrically connected to the copper wire on the PCB board 1, thereby achieving electrical conduction between the connector and the PCB board 1. Since the tightening screws continuously apply pressure to the conductive block 12, the conductive block 12 can continue to contact the PCB board 1, thereby stably connecting the circuit of the PCB board 1.

[0054] As an embodiment of the present invention, refer to Figure 3 , arc-shaped grooves 9 are symmetrically provided on both side walls of the plurality of fixed blocks 19 , a rotating plate 7 is slidably installed in the arc-shaped groove 9 , and an external connection hole 8 for passing the wire 6 is provided on the rotating plate 7 .

[0055] Arc grooves 9 are provided on both side walls of multiple fixed blocks 19, and a rotating plate 7 is slidably installed in the arc grooves 9. An external connection hole 8 is provided on the rotating plate 7. When performing wiring operations, a person manually passes the wire 6 into the first sliding groove 11 from the position of the external connection hole 8, and then uses a screwdriver to tighten the fastening screw to press the clamping plate 10 downward to tighten the wire 6. At this time, the wire 6 is parallel to the PCB board 1. If this setting affects the PCB board 1, a person manually bends the wire 6 upward. At this time, the rotating plate 7 rotates counterclockwise along the arc groove 9 as the wire 6 moves upward. The wire 6 is rotated to a position perpendicular to the PCB board 1, which does not hinder the installation operation of parts next to the PCB board 1 and reduces the space occupancy of the connector.

[0056] As an embodiment of the present invention, refer to Figure 4 , the locking mechanism includes:

[0057] A penetrating rod 14 is fixedly connected to the bottom wall of the housing 2;

[0058] Locking block 15: Two locking blocks 15 are elastically connected to the side wall of the penetrating rod 14, and both locking blocks 15 are made of elastic material.

[0059] When the shell 2 and the PCB board 1 are installed, the shell 2 is placed on the PCB board 1 by hand. The PCB board 1 is provided with a positioning hole that cooperates with the penetration rod 14. When the shell 2 is placed on the PCB board 1 by hand, the penetration rod 14 is aligned with the position of the positioning hole, the penetration rod 14 is inserted into the positioning hole, and is continuously pushed downward. The locking blocks 15 on both sides of the penetration rod 14 contact the side walls of the positioning hole. The locking blocks 15 are subjected to pressure and retracted into the inside of the penetration rod 14. The penetration rod 14 continues to move downward, so that when the two locking blocks 15 move to the bottom wall of the PCB board 1, the two locking blocks 15 are not subjected to the pressure of the positioning holes and expand outward. The top wall of the locking block 15 contacts the bottom wall of the PCB board 1, limiting the upward movement of the penetration rod 14, thereby achieving the purpose of fixing the shell 2 on the PCB board 1. In the above process, the shell 2 does not need to be soldered to the PCB board 1 to fix it. After the connector is integrated into a whole, it can also facilitate the connection operation of the connector and the PCB board 1.

[0060] As an embodiment of the present invention, refer to Figure 1 The two ends of the top wall of the shell 2 are symmetrically threaded with locking screws 5, which extend to the penetrating rod 14. The bottom end of the locking screw 5 is threaded with a sliding block 16. The penetrating rod 14 is provided with a built-in cavity. A spring washer 17 is fixedly installed at the end of the built-in cavity away from the shell 2, and two locking blocks 15 are fixedly connected to the spring washer 17.

[0061] The locking screws 5 are threadedly connected at both ends of the top wall of the shell 2. The locking screws 5 extend through the shell 2 to the penetrating rod 14 and continue to extend into the built-in cavity of the penetrating rod 14. A spring washer 17 is fixedly installed at the end of the built-in cavity of the penetrating rod 14 away from the shell 2. The two locking blocks 15 are fixedly connected to the two sides of the spring washer 17 and are slidably connected to the side walls of the penetrating rod 14. When fixing the shell 2, the locking screw 5 threadedly connected to the shell 2 is manually rotated. The locking screw 5 moves downward after rotation, and the sliding block 16 threadedly connected to the locking screw 5 slides downward. The bottom wall of the sliding block 16 contacts the top walls of the two locking blocks 15, forming a horizontal thrust on the two locking blocks 15, and the two locking blocks 15 are fixedly connected. 5 is pushed toward the two side walls of the penetration rod 14, and the two locking blocks 15 move outward and contact the bottom wall of the PCB board 1, completing the fixation of the shell 2. When the connector needs to be disassembled, the shell 2 needs to be disassembled, and the locking screw 5 is manually rotated counterclockwise, and the locking screw 5 moves upward. At this time, the sliding block 16 moves upward with the counterclockwise rotation of the locking screw 5, and the sliding block 16 rises to a position above the two locking blocks 15, canceling the thrust on the two locking blocks 15. The two locking blocks 15 are subjected to the elastic tension of the spring washer 17 and shrink toward the inner wall of the penetration rod 14. At this time, the shell 2 can be pulled out by pulling it upward, thereby improving the versatility of the connector and facilitating the connection and installation operation of the connector.

[0062] As an embodiment of the present invention, refer to Figure 4 The inner side walls of the two locking blocks 15 are provided with internal threads that cooperate with the locking screws, the end of the sliding block 16 facing the spring washer 17 is an inclined opening, and the two side walls of the penetrating rod 14 are provided with a second sliding groove 20.

[0063] In the prior art, when the thickness of the PCB board 1 is relatively thin, after the connector is inserted, there may be a gap between the top wall of the locking block 15 and the bottom wall of the PCB board 1, resulting in a poor fixing effect; therefore, the outer wall of the sliding block 16 is provided with an external thread, and the sliding block 16 is threadedly connected to the internal threads of the inner walls of the two locking blocks 15. When the locking screw 5 is rotated counterclockwise, the sliding block 16 moves downward, pushing the two locking blocks 15 toward the two sides of the penetrating rod 14. When the sliding block 16 moves downward to a certain distance, the two The locking block 15 is squeezed and contacted on the side wall of the locking screw 5 by the spring washer 17, and the thread on the inner wall of the locking block 15 cooperates with the locking screw 5. As the locking screw 5 continues to rotate and the head of the locking screw 5 abuts against the top wall of the shell 2, the two locking blocks 15 move upward along the second slide groove 20 and then abut against the bottom wall of the PCB board 1. When the connector faces different PCB boards 1 thicknesses, the adaptability of the locking mechanism to the thickness of the PCB board 1 can be adjusted, thereby improving the stability of the locking mechanism.

[0064] As an embodiment of the present invention, refer to Figure 3 An arc-shaped plate 23 is fixedly connected between two adjacent fixing blocks 19 .

[0065] An arc-shaped plate 23 is fixedly connected between every two adjacent fixed blocks 19, and an arc-shaped arc groove 9 is formed between the arc-shaped plate 23 and the rotating plate 7. Because the bottom end of the arc-shaped plate 23 contacts the edge of the clamping plate 10 that has not moved downward in the initial state, the bottom of the arc-shaped arc groove 9 leads to the area below the clamping plate 10. Therefore, the wire 6 can smoothly enter the appropriate wiring position under the action of the arc groove 9; it is more convenient to make the wiring point of the wire 6 contact the copper wire 6 on the PCB board 1, so that the conduction effect of the electrical signal is better.

[0066] As an embodiment of the present invention, refer to Figure 6 and Figure 7 A threaded boss 24 is fixedly connected to the top wall of the pressing plate 10 , and the threaded boss 24 is threadedly connected to the pressing screw 4 . A plurality of reinforcing ribs 22 are radially mounted on the threaded boss 24 .

[0067] A threaded boss 24 is fixedly connected to the top wall of the clamping plate 10, and a thread is provided on the inner wall of the threaded boss 24. The tail of the clamping screw 4 is threadedly connected to the inner wall of the threaded boss 24, and a plurality of reinforcing ribs 22 are fixedly connected around the threaded boss 24. The plurality of reinforcing ribs 22 form a vertical supporting force for the clamping plate 10 located on the bottom wall of the threaded boss 24. When the clamping screw 4 pushes the clamping plate 10 downward, the plurality of reinforcing ribs 22 provide supporting force for the clamping plate 10, thereby enhancing the structural rigidity of the clamping plate 10. It is only necessary to thread a clamping screw 4 at the center position of the clamping plate 10, and there is no need to connect multiple clamping screws 4 to improve the stability of the clamping plate 10 in clamping the wire 6.

[0068] As an embodiment of the present invention, refer to Figure 4 A pull block 25 is fixedly connected to the top wall of the locking screw 5.

[0069] A connecting block 25 is fixed on the top wall of the locking screw 5. When the locking screw 5 needs to be rotated, a person holds the block 25 on the locking screw 5 and turns the block 25 with force. The block 25 drives the locking screw 5 to rotate. Since the locking screw 5 is small in size, it is inconvenient to rotate the locking screw 5 alone. Fixing the connecting block 25 on the locking screw 5 makes it convenient for people to manually rotate and lock the screw 5, thereby improving the convenience of the locking operation.

[0070] A PCB board connection structure is suitable for the above-mentioned PCB board connector, including a PCB board 1, a plurality of wiring holes 3 are opened on the PCB board 1, and a circular metal sheet 13 is fixedly connected to the top of the plurality of wiring holes 3. Two locking holes 18 are symmetrically opened on the PCB board 1.

[0071] The tops of the plurality of wiring holes 3 are all fixedly connected with round metal sheets, and two locking holes 18 are symmetrically opened on the PCB board 1 .

[0072] A plurality of wiring holes 3 are symmetrically provided on the PCB board 1, and a circular metal sheet 13 is fixedly connected to the top of each of the plurality of wiring holes 3. The PCB is welded to external electronic components through the circular metal sheets 13 on the plurality of wiring holes 3. By fixing the circular metal sheets 13 on the plurality of wiring holes 3, the conductive contact area on the wiring holes 3 is increased. When the clamping plate 10 pushes the conductive block 12 downward, the bottom wall of the conductive block 12 contacts the top wall of the circular metal sheet 13, thereby electrically conducting the conductive block 12 and the circular metal sheet 13, thereby improving the stability of the electrical connection between the connector and the PCB board 1.

[0073] Working principle: when it is necessary to connect the lines of PCB board 1, the person manually inserts the wire 6 to be connected into the first slide groove 11 through the through hole. When the person manually passes the wire 6 to be connected into the first slide groove 11, the person manually rotates the wiring fixing structure in the first slide groove 11, and the wiring fixing mechanism moves downward to press the wire interface to be connected onto the PCB board 1. The person manually uses a screwdriver to tighten the fastening screw, and the pressing plate 10 on the wiring fixing mechanism moves downward. The pressing plate 10 presses the conductive wire 6 tightly against the conductive block 12 and continues to push the conductive block 12 downward. The conductive block 12 is pushed downward by the pressing plate 10. When the shell is fixedly installed on the PCB board 1, the bottom wall of the conductive block 12 contacts the copper wire on the PCB board 1, and the conductive block 12 is electrically conductive with the copper wire on the PCB board 1, thereby achieving electrical conduction between the connector and the PCB board 1. At this time, the wire 6 and PCB board 1 are arranged in a parallel position. If such a setting affects the PCB board 1, the person manually bends it upward The wire 6, at this time, the rotating plate 7 rotates counterclockwise along the arc groove 9 as the wire 6 moves upward, and the wire 6 is rotated to a position perpendicular to the PCB board 1, which does not hinder the installation operation of parts beside the PCB board 1 and reduces the space occupancy of the connector. The locking screw 5 is manually turned, and the locking screw 5 drives the sliding block 16 to move downward. The sliding block 16 pushes the locking blocks 15 on the two side walls of the penetration rod 14 outward, and the top wall of the locking block 15 rests on the bottom wall on the PCB board 1, thereby locking the connector on the PCB board 1. The locking screw 5 is manually turned counterclockwise, and the locking screw 5 moves upward, and the sliding block 16 also moves upward, canceling the thrust on the two locking blocks 15, and the spring washer 17 elastically contracts, retracting the two locking blocks 15 back into the penetration rod 14, canceling the fixation of the connector, and then removing the connector from the PCB board 1, improving the convenience of connector installation operation, and no need to solder a connector to the PCB board 1 in advance to achieve the connection between the connector and the PCB board 1.

[0074] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
