[0005] In order to achieve the above purpose, the utility model is implemented by the following technical scheme: a rectangular printed circuit connector, which comprises a main connecting seat, a hexagonal adjusting handle, a first positioning groove, an expansion connecting seat, a fixed plate, a rotating cavity, an internal thread cavity, a rotating shaft and a limiting screw rod, the left side of the main connecting seat is provided with the hexagonal adjusting handle, the right end face of the main connecting seat is provided with the first positioning groove, the inside of the main connecting seat is provided with the rotating cavity, the right side of the rotating cavity is provided with the internal thread cavity, the internal thread cavity is rotatably provided with the rotating shaft, the outer side of the rotating shaft is provided with the limiting screw rod, the right side of the main connecting seat is provided with the expansion connecting seat, and the right side of the expansion connecting seat is provided with the fixed plate.

[0006] Further, the limiting screw rod is internally provided with a positioning groove, the rotating shaft annular side is provided with a positioning block, and the limiting screw rod is slidably clamped with the positioning block through the positioning groove.

[0007] Further, the rotating shaft left end is provided with a rotating limiting block, and the rotating limiting block closely slides along the inner wall of the rotating cavity.

[0008] Furthermore, the left end of the rotation limit block is provided with an internal hexagonal adjustment seat, which is matched with the hexagonal adjustment handle.

[0009] Furthermore, the limiting screw meshes with the inner wall of the internal thread cavity, and the left and right end faces of the expansion connector are provided with limiting through holes, through which the limiting threaded rod passes through the expansion connector.

Finally, it engages with the fixing hole of the fixing plate, thereby further fixing the expansion connector. This allows for the assembly of a suitable connector for use. The operation is simple and convenient. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a rectangular printed circuit connector, including a main connector 1, a hexagonal adjustment handle 2, a first positioning groove 913, an expansion connector 4, a fixing plate 5, a rotating cavity 6, an internal thread cavity 7, a rotating shaft 8, and a limiting screw 9. The hexagonal adjustment handle 2 is provided on the left side of the main connector 1, and the first positioning groove 913 is provided on the right end face of the main connector 1. The rotating cavity 6 is provided inside the main connector 1, and the internal thread cavity 7 is provided on the right side of the rotating cavity 6. The rotating shaft 8 is rotatably arranged inside the internal thread cavity 7, and the limiting screw 9 is sleeved on the outer side of the rotating shaft 8. The expansion connector 4 is provided on the right side of the main connector 1, and the fixing plate 5 is provided on the right side of the expansion connector 4. This design solves the problem that the original rectangular printed circuit connectors need to be replaced with different specifications of connectors according to different circuits.

[0024] As the first embodiment of this utility model: a positioning groove 91 is provided inside the limiting screw 9, and a positioning block 81 is provided on the annular side of the rotating shaft 8. The rotating shaft 8 can drive the positioning block 81 to rotate. The limiting screw 9 is slidably engaged with the positioning block 81 through the positioning groove 91. The design of the positioning block 81 and the positioning groove 91 allows the rotating shaft 8 to drive the limiting screw 9 to rotate together, while the limiting screw 9 can move relative to the rotating shaft 8 along its axial direction. A rotation limiting block 82 is provided at the left end of the rotating shaft 8. The rotation limiting block 82 slides tightly along the inner wall of the rotating cavity 6. 6 can fix its position without affecting the rotation of the rotation limit block 82, thereby fixing the position of the rotating shaft 8. The left end of the rotation limit block 82 is provided with an internal hexagonal adjustment seat 83, which matches the hexagonal adjustment handle 2. The user can drive the internal hexagonal adjustment seat 83 to rotate through the hexagonal adjustment handle 2. The limit screw 9 meshes with the inner wall of the internal thread cavity 7. The rotation of the limit screw 9 can make it move horizontally under the action of the internal thread cavity 7. Limit through holes 41 are opened through the left and right end faces of the extension connecting seat 4. The limit thread rod passes through the limit through hole 41. The through hole 41 passes through the expansion connector 4. After the limiting threaded rod passes through the limiting through hole 41, it can limit the position of the expansion connector 4. The left end face of the fixing plate 5 has a fixing hole 51. The limiting threaded rod is engaged with the fixing plate 5 through the fixing hole 51. The fixing plate 5 can fix the position of the last set of expansion connectors 4. The left end face of the expansion connector 4 is provided with a first positioning block 8142. The first positioning block 8142 is slidably engaged with the first positioning groove 913. The first positioning block 8142 and the second positioning block 8152 can fix the position of the expansion connector 4. The first positioning block 8142 has a conductive contact 421 at its lower end, and the first positioning groove 913 has a conductive base 31 at its lower end. The expansion connector 4 is electrically connected to the conductive base 31 through the conductive contact 421. This design enables several sets of expansion connectors 4 to be electrically connected to the main connector 1. The left end face of the fixing plate 5 has a second positioning block 8152, and the right end face of the expansion connector 4 has a second positioning groove 9143. The second positioning groove 9143 and the second positioning block 8152 slide and engage. This design can achieve the positioning effect of the fixing plate 5.

[0025] As a second embodiment of this utility model: the user can choose to add an appropriate number of expansion connectors 4 according to the specific situation of the circuit. For example, when the circuit uses a 16-pin plug for connection, two more sets of expansion connectors 4 need to be added to the main connector 1. Figure 1As shown, during installation, first remove the fixing plate 5 from the right end face of the main connecting seat 1. Then, engage the first positioning block 8142 of the first set of expansion connecting seats 4 with the first positioning groove 913. Next, engage the first positioning block 8142 of the second set of expansion connecting seats 4 with the second positioning groove 9143 of the first set of expansion connecting seats 4. Finally, engage the second positioning block 8152 of the fixing plate 5 with the second positioning groove 9143 of the second set of expansion connecting seats 4. This completes the initial assembly. Then, remove the hexagonal adjusting handle 2 and connect it to the inner... After the hexagonal adjusting seat 83 is connected and rotates, it drives the rotating limiting block 82 and the rotating shaft 8 to rotate. The rotating shaft 8 drives the limiting screw 9 to rotate together through the positioning block 81 and the positioning groove 91. Since the limiting screw 9 meshes with the inner wall of the internal thread cavity 7, the rotation of the limiting screw 9 causes it to move along the axis of the rotating shaft 8, thereby extending out of the internal thread cavity 7 and passing through the limiting through hole 41 of the expansion thread seat in sequence. Finally, it engages with the fixing hole 51 of the fixing plate 5, thereby completing the further fixing of the expansion connecting seat 4.
