Description

Technical Field

[0001] The present invention relates to the technical field of connector processing, and particularly relates to a board-to-board connector structure with a plug block structure. Background Art

[0002] The board-to-board connector is the connector product with the strongest transmission ability among all connector product types at present, and is mainly applied to industries such as power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, household appliances, and military manufacturing. In actual use, in order to better conduct high voltage, the general practice is to increase the creepage distance between terminals. There is also a practice of setting plug blocks on the connector in the market, and the biggest defect of this practice is that: since the size of the plug guide groove in the automatic plug-in machine is fixed, therefore, the plug block cannot be inserted through the automatic plug-in machine in the standard production track and needs to be inserted manually later, which seriously affects the production efficiency. In view of this situation, it is urgent to solve. Summary of the Invention

[0003] Based on this, the purpose of the present invention is to provide a board-to-board connector structure with a plug block structure, by changing the structure of the plug block, enabling it to be inserted through the automatic plug-in machine in the standard production track, on the one hand, improving the production efficiency, and on the other hand, ensuring the quality of the product.

The female end connector includes a first insulating housing, a plurality of first terminal slots, and a plurality of first conductive terminals assembled in the first terminal slots and adapted to be connected to a circuit board. The male end connector includes a second insulating housing, a plurality of second terminal slots, and a plurality of second conductive terminals assembled in the second terminal slots and adapted to be connected to another circuit board. A female end plug block structure is provided between two adjacent first terminal slots on the first insulating housing, and a male end plug block structure adapted to cooperate with the female end plug block structure is provided between two adjacent second terminal slots on the second insulating housing.

[0007] As a preferred solution, when the fitting block is inserted into the relief groove A, the extension block extends out of the first insulation housing and the length of the exposed part is greater than the length of the exposed part of the first conductive terminal pin.

[0008] As a preferred solution, the shape of the fitting block is trapezoidal; the shape of the relief groove A is trapezoidal corresponding to the fitting block.

[0009] As a preferred solution, a reinforcing rib is provided on one side surface of the fitting block facing the relief groove A.

[0010] As a preferred solution, an insertion portion for inserting into the relief groove B is formed on one side of the male-end insulation module, and a relief groove C for inserting the plug block B is formed on the other side of the male-end insulation module.

[0013] As a preferred solution, the height of the part where the upper surface of the plug block B extends out of the upper surface of the second insulation housing is higher than the height of the part where the second conductive terminal pin exposes the second insulation housing; one end of the plug block B away from the male-end insulation module extends out of the second insulation housing.

[0014] As a preferred solution, reinforcing ribs are provided on both opposite side surfaces of the plug block B.

[0016] 1. The female-end plug block structure includes a female-end insulation module and a plug block A, and the male-end plug block structure includes a male-end insulation module and a plug block B. During production, since the shape of the female-end insulation module corresponds to the first terminal slot, and the shape of the male-end insulation module corresponds to the second terminal slot, therefore, the female-end insulation module and the male-end insulation module can first be respectively inserted into the first insulation housing and the second insulation housing through automatic plug-in.

Detailed implementation manners

[0029] To further understand the features, technical means, and specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0030] Please refer to Figures 1-5 As shown in the figure: A board-to-board connector structure with a plug block structure includes a female end connector and a male end connector. The female end connector includes a first insulating housing 10, a plurality of first terminal slots 26, and a plurality of first conductive terminals 28 assembled in the first terminal slots 26 and adapted to be connected to a circuit board. The male end connector includes a second insulating housing 12, a plurality of second terminal slots 29, and a plurality of second conductive terminals 27 assembled in the second terminal slots 29 and adapted to be connected to another circuit board. A female end plug block structure 11 is provided between two adjacent first terminal slots 26 on the first insulating housing 10, and a male end plug block structure 13 that cooperates with the female end plug block structure 11 is provided between two adjacent second terminal slots 29 on the second insulating housing 12.

[0031] The female end plug block structure 11 includes a female end insulating module 15 and a plug block A 14; the male end plug block structure 13 includes a male end insulating module 16 and a plug block B 17; the shape of the female end insulating module 15 corresponds to that of the first terminal slot 26, and the plug block A 14 is movably inserted on the side of the female end insulating module 15 away from the male end connector; the shape of the male end insulating module 16 corresponds to that of the second terminal slot 29, and the plug block B 17 is movably inserted on the side of the male end insulating module 16 away from the female end connector; when the female end connector and the male end connector are in a connected state, the male end insulating module 16 is inserted into the female end insulating module 15.

[0032] A relief groove A is formed on one side of the female end insulating module 15, and a relief groove B 22 for inserting the male end insulating module 16 is provided on the other side of the female end insulating module 15; the plug block A 14 includes a fitting block 20 corresponding to the relief groove A and an extension block 18 integrally formed with the fitting block 20.

[0033] When the fitting block 20 is inserted into the relief groove A, the extension block 18 extends out of the first insulating housing 10 and the length of the exposed part is greater than the length of the exposed part of the pin of the first conductive terminal 28. Through such a structural setting, the creepage distance is increased.

[0034] The shape of the fitting block 20 is set to a trapezoid; the shape of the relief groove A is set to a trapezoid corresponding to the fitting block 20. After the fitting block is inserted into the relief groove A, through the cooperation of the trapezoid and the trapezoid, the fitting block can be firmly embedded into the relief groove A without loosening.

[0035] Reinforcing ribs 19 are provided on one side of the fitting block 20 facing the relief groove A, so that the fitting block can be in interference fit with the relief groove A, further improving the stability of the fitting; reinforcing ribs 19 are provided on both opposite side surfaces of the plug block B17, so that the plug block B can be in interference fit with the relief groove C, improving the stability of the fitting.

[0036] An insertion portion 21 for inserting into the relief groove B22 is formed on one side of the male terminal insulating module 16, and a relief groove C23 for inserting the plug block B17 is formed on the other side of the male terminal insulating module 16. In order to make the upper surface of the plug block B17 extend out of the upper surface of the second insulating housing 12 and the end of the plug block B17 away from the male terminal insulating module 16 extend out of the second insulating housing 12, the plug block B17 is set to a C shape.

[0037] When the plug block B17 is inserted into the relief groove C23, the upper surface of the plug block B17 extends out of the upper surface of the second insulating housing 12. The height of the part where the upper surface of the plug block B17 extends out of the upper surface of the second insulating housing 12 is higher than the height of the part where the pin of the second conductive terminal 27 exposes the second insulating housing 12; the end of the plug block B17 away from the male terminal insulating module 16 extends out of the second insulating housing 12. Through such a structural setting, the creepage distance is further increased.

[0038] In this embodiment, the female terminal plug block structure includes a female terminal insulating module and a plug block A, and the male terminal plug block structure includes a male terminal insulating module and a plug block B. During production, since the shape of the female terminal insulating module corresponds to the first terminal slot and the shape of the male terminal insulating module corresponds to the second terminal slot, therefore, the female terminal insulating module and the male terminal insulating module can first be respectively inserted into the first insulating housing and the second insulating housing through automatic plug-in. Subsequently, after completing the plug-in action of this connector, finally, the plug block A is correspondingly inserted into the female terminal insulating module and the plug block B is correspondingly inserted into the male terminal insulating module immediately, so as to realize insertion through an automatic plug-in machine on a standard production track, improving production efficiency on the one hand and ensuring product quality on the other hand.
