Therefore, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features.

[0038] like Figure 1 As shown, this embodiment provides a floating blind-mating connector for use with Figure 2 The long pin header 1 shown is plugged in and comprises: a connector body 2;

[0039] The connector body 2 includes a female end socket section 3 and a groove section 4. The female end socket section 3 is connected to the groove section 4. In this embodiment, the connection method here is integrated molding.

[0040] Reference Figure 3 and Figure 4 The female end socket section 3 is provided with a female slot 5, such as Figure 4The figure shows an enlarged view of the female slot 5, which includes a guide portion 51 and a fixing portion 52. The guide portion 51 is communicated with the fixing portion 52, and the end of the guide portion 51 away from the fixing portion 52 is the open end of the guide portion 51, and the end of the guide portion 51 connected to the fixing portion 52 is the bottom end of the guide portion 51.

[0041] The guide portion 51 and the fixed portion 52 are coaxial, that is, the central axes of the guide portion 51 and the fixed portion 52 coincide, and the internal cross-sectional area of ​​the guide portion 51 is not less than the internal cross-sectional area of ​​the fixed portion 52. In this embodiment, the cross section refers to a cross section perpendicular to the central axis of the above-mentioned guide portion 51, and all cross sections in the subsequent description refer to cross sections perpendicular to this central axis.

[0042] The internal cross-sectional area of ​​one end of the guide portion 51 connected to the fixing portion 52 is the same as the internal cross-sectional area of ​​the fixing portion 52, and is also the smallest internal cross-sectional area of ​​the guide portion 51. The closer to the direction of the slot connecting the guide portion 51 to the outside world, the larger the internal cross-sectional area of ​​the guide portion 51.

[0043] In this embodiment, a smooth arc surface is formed between the opening end and the bottom end of the guide portion 51, the internal cross-sections of both ends of the fixing portion 52 are exactly the same, the vertical cross-section of the inner wall of the fixing portion 52 is a rectangle, and the fixing portion 52 is located between the guide portion 51 and the groove segment 4.

[0044] like Figure 3 As shown, the groove section 4 is provided with a plurality of pin holes 6, the hole arrangement of the pin holes 6 matches the pin arrangement of the long pin header 1, and the female slot 5 is connected to the pin holes 6. The hole arrangement of the pin holes 6 in this embodiment is consistent with the position and number of the pin arrangement of the long pin header 1. In another specific embodiment, the number of the pin holes 6 can also be more than the number of the pins of the long pin header 1. As long as the long pin header 1 can be inserted into the pin holes 6, the two can be considered to match.

[0045] In this embodiment, after the connector body 2 of the utility model is plugged into the long-pin header 1, the long-pin header 1 can be plugged into the mating female connector 9. During the plugging process, the guide portion 51 plays a guiding role, and the mating female connector 9 slides into the fixing portion 52 along the inner wall of the guide portion 51 and is then fixed in the groove of the fixing portion 52.

[0046] like Figure 3As shown, a plurality of first slots 7 are correspondingly arranged at the opening of the pin row hole 6 on the groove section 4 close to the female end socket section 3, and each opening of the pin row hole 6 close to the female end socket section 3 corresponds to a first slot 7, and the first slots 7 are all connected to the female socket 5, and a plurality of second slots 8 are correspondingly arranged at the opening of the pin row hole 6 on the groove section 4 away from the female end socket section 3, and each opening of the pin row hole 6 away from the female end socket section 3 corresponds to a second slot 8.

[0047] That is, the first slot 7 and the second slot 8 are respectively formed at both ends of the pin hole 6, so the first slot 7 and the second slot 8 respectively cover the two ends of the pin hole 6, and penetrate the groove section 4 in the order of the first slot 7, the pin hole 6, and the second slot 8.

[0048] The cross-sectional areas of the first slotted hole 7 and the second slotted hole 8 are both larger than the cross-sectional area of ​​the pin-row hole 6 . In this embodiment, the pin-row hole 6 , the first slotted hole 7 and the second slotted hole 8 are coaxial.

[0049] like Figure 5 The first slot 7 is shown, and the first slot 7 includes a first groove 71 and a second groove 72. Figure 6 The second slot 8 is shown, and the second slot 8 includes a third groove 81 and a fourth groove 82. In this embodiment, the vertical section of the first groove 71 is a rectangle, the vertical section of the second groove 72 is a trapezoid, and the vertical section of the third groove 81 is a trapezoid in the opposite direction to the vertical section of the second groove 72.

[0050] The first groove 71 , the second groove 72 , the pin hole 6 , the third groove 81 and the fourth groove 82 are connected to each other in sequence along a direction parallel to the connector body 2 , and the first groove 71 , the second groove 72 , the pin hole 6 , the third groove 81 and the fourth groove 82 are coaxial.

[0051] The cross-sectional area of ​​the second groove 72 near the pin hole 6 is smaller than the cross-sectional area of ​​the first groove 71, and the cross-sectional area of ​​the third groove 81 near the pin hole 6 is smaller than the cross-sectional area of ​​the fourth groove 82. The cross-sectional size and shape of the side where the second groove 72 is connected to the pin hole 6 are exactly the same as those of the pin hole 6, and the cross-sectional size and shape of the side where the third groove 81 is connected to the pin hole 6 are exactly the same as those of the pin hole 6.

[0052] In this embodiment, the long-legged pin header 1 is inserted from the opening of the fourth groove 82, i.e., the end connected to the outside. After the pins of the long-legged pin header 1 pass through the fourth groove 82, they can be easily inserted into the pin header hole 6 through the guiding effect of the inner wall of the third groove 81.

[0053] The clearance between the pin hole 6 and the pin of the long pin 1 is matched, and the connector body 2 can float back and forth on the pin of the long pin 1. In this way, after the connector body 2 is plugged into the mating female connector 9, the pin of the long pin 1 can pass through the mating female connector 9 and continue to plug in, and the connector body 2 will not hinder the pin of the long pin 1 from moving forward in the plugging direction.

[0054] The cross section of the pin hole 6 is square. In this embodiment, the cross sections of both ends of the pin hole 6 are square of the same size, so the pin hole 6 is a square hole. The square pin hole 6 in this embodiment is to adapt to the square pins of the long-leg pin 1 so that the pin hole 6 matches the pin gap.

[0055] The cross-sections of the first groove 71 and the fourth groove 82 are square. In this embodiment, the cross-section of the end of the first groove 71 connected to the female slot 5 is slightly larger than the other end, and the cross-section of the end of the fourth groove 82 connected to the outside is slightly larger than the other end. In another specific implementation, the cross-sections of both ends of the first groove 71 and the fourth groove 82 can also be the same, and made into square holes.

[0056] Based on the above technical solution, the following is a complete plugging process of the connector body 2 and other components in one embodiment:

[0057] In this embodiment, the application scenario of the connector body 2 is the combined assembly of the two sides of the wheel hub of a two-wheeled electric vehicle, such as Figure 7 As shown, a PCB board 12 is installed on the left wheel hub bracket 10 and the right wheel hub bracket 11 respectively, and a matching female connector 9 is provided on the PCB boards 12 on the left and right sides respectively.

[0058] First, align one end of the long pin of the long pin header 1 with the fourth groove 82 of the connector body 2 and insert it, and then slide it into the pin header hole 6 through the third groove 81 .

[0059] Then insert the pins on the other side of the long pin header 1 into the PCB board 12 of the right wheel hub bracket 11, align with the mating female connector 9 of the right PCB board 12 and insert it so that the pin header connecting plastic 101 fits tightly with the mating female connector 9 on the right side.

[0060] Then, the assembly of the connector body 2, the long-pin pin header 1 and the wheel right-side hub bracket 11 is inserted toward the wheel left-side hub bracket 10. At this time, the connector body 2 is self-aligned with the matching female connector 9 of the wheel left-side hub bracket 10 through the female slot 5 to achieve blind insertion.

[0061] During this process, the mating female connector 9 on the left side slides into the fixing part 52 through the guide part 51 and is stuck. In this embodiment, the inner wall of the fixing part 52 should be able to match the clearance of the mating female connector 9 to achieve a fixing effect. There is an allowable deviation value in the blind insertion process. This deviation value is the difference between the length of the long side of the inner wall of the guide part 51 and the length of the long side of the mating female connector 9. As long as it is within this difference range, the mating female connector 9 can be smoothly fixed in the female slot 5, and the connector body 2 and the mating female connector 9 can be accurately plugged together without complete alignment. In this way, even when the line of sight is blocked and the alignment space is narrow, the mating female connector 9 can be smoothly aligned with the connector body 2, plugged in and fixed.

[0062] The hole arrangement of the mating female connector 9 is the same as the pin arrangement of the long-legged pin header 1. Keeping the connector body 2 stationary, the pins of the long-legged pin header 1 can continue to pass through the mating female connector 9, the PCB board 12 and the left-side wheel hub bracket 10 on the left in sequence, until the right-side component, including the right-side wheel hub bracket 11, the right-side PCB board 12, the right-side mating female connector 9 and the long-legged pin header 1, is mated through the connector body 2 and the left-side component, including the left-side wheel hub bracket 10, the left-side PCB board 12 and the left-side mating female connector 9. Figure 8 As shown, the left wheel hub bracket 10 and the right wheel hub bracket 11 on the left and right sides are now closed. It should be noted that the cross-sectional area of ​​the fourth groove 82 should be larger than the pin connection 102 of the long-pin header pin 1, so that the exposed portion of the pin connection 102 can be fully inserted into the fourth groove 82, so as to achieve the closing of the left wheel hub bracket 10 and the right wheel hub bracket 11.

[0063] In summary, the utility model provides a floating blind-plug connector, which can realize blind plugging of the connector body 2 within the above-mentioned allowable deviation value through the guide portion 51, so that the connector body 2 and the mating female connector 9 can be aligned, and the long-pin header pin 1 can be easily inserted into the mating female connector 9 through the connector body 2, which solves the problem that when the line of sight in a small space is blocked, the long-pin header pin 1 is difficult to accurately plug into the mating female connector 9, resulting in pin damage, subsequent poor assembly or waste of resources, saving costs and improving the efficiency of assembly by staff; at the same time, the connector body 2 also has a fixing effect on the pins, avoiding the problem of plugging failure and pin damage caused by pin shaking; and the floating function of the connector body 2 on the pins also ensures that the closing of the left wheel hub bracket 10 and the right wheel hub bracket 11 is not affected during the plugging process.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
