Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a floating compensation connector. Background Technology

[0002] In the field of board-to-board connectors, due to the accumulation of tolerances caused by multiple connectors during the assembly of different circuit boards / conductive copper busbars, as well as the thermal expansion and contraction effect generated by Joule heating during use, the relative positions of the two boards may shift, thus affecting the assembly and normal operation of the electrical connectors. Therefore, floating connectors are used for board-to-board connections.

[0003] However, existing floating connectors generally have a cover plate on the base to restrict the axial movement of the base. However, due to factors such as vibration and impact during operation, the cover plate and the base may sometimes completely lose contact, resulting in relative axial movement of the base relative to the main body. This causes the two to lose contact, ultimately leading to a power outage at the microsecond level or longer, causing a temporary failure of the electrical connection between the connector and the mating terminal, and affecting the reliability of the contact. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a floating compensation connector that can achieve radial displacement compensation while ensuring that the connector will not fail due to power loss after being subjected to vibration and impact.

[0005] This utility model is achieved through the following technical solution:

[0006] A floating compensation connector, characterized in that it comprises:

[0007] A housing having a floating hole and a step, the step extending outward from the first outer peripheral wall of the housing, the housing being used to connect to an external object A;

[0008] A substrate is disposed within the floating hole, and a first gap exists between the second outer peripheral wall of the substrate and the first inner peripheral wall forming the floating hole. The substrate is provided with a channel and a flange structure. The flange structure extends outward from the second outer peripheral wall and forms a cavity within the flange structure. The step is accommodated within the cavity, and the flange structure includes a first flange and a third flange located on both sides of the step. One side of the step abuts against the first flange.

[0009] An elastic element, one side of which abuts against the third flange and the other side of which abuts against the step;

[0010] A contact element, disposed within the channel, is used to connect to an external object B.

[0011] Furthermore, the flange structure also includes a second flange, the two ends of which are fixedly connected to the first flange and the third flange, respectively.

[0012] Furthermore, there is a second gap between the second flange and the step, the width of the second gap being greater than or equal to the width of the first gap.

[0013] Furthermore, the step has at least one protrusion on the side facing the first flange, and the protrusion abuts against the first flange.

[0014] Furthermore, the number of protrusions is two, and the two protrusions are arranged in concentric circles.

[0015] Furthermore, the protrusion is annular and coaxially arranged with the floating hole.

[0016] Furthermore, the first flange is perpendicular to the second outer peripheral wall, and the third flange is parallel to the first flange.

[0017] Furthermore, the first upper surface of the first flange is coplanar with the second upper surface of the substrate.

[0018] Furthermore, a limiting block is protruding on the housing, the limiting block is engaged with the object A, and the limiting block is arranged in a ring shape.

[0019] Furthermore, the elastic element is a wave spring.

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] 1. This utility model provides a floating hole on the shell, into which the substrate is placed, allowing the substrate to move radially relative to the shell. This avoids the influence of positional errors between object B and object A, as well as positional errors caused by other factors.

[0022] 2. The floating compensation connector provided by this utility model forms a flange structure on the substrate and a step on the housing. The step is set in a cavity within the flange structure, and an elastic element is provided so that the step and the first flange always abut against each other. This allows the present application to avoid the disconnection between object A and object B caused by vibration during operation. Attached Figure Description

[0028] The following detailed, non-limiting description of the utility model's technical solution, in conjunction with preferred embodiments and accompanying drawings, is provided. In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figure 1 As shown, a floating compensation connector according to an embodiment of this utility model is used to provide a floating connection between object A and object B. Specifically, both object A and object B are circuit boards. The floating compensation connector provided by this utility model can be fixed to object A and electrically connected to object A by means of soldering, bonding, or plugging. Pins on object B can be plugged into the floating compensation connector to achieve an electrical connection between object A and object B. Furthermore, the floating compensation connector provided by this utility model can provide radial floating compensation to avoid the influence of positional errors between object B and object A caused by other factors. It also prevents the connection between object A and object B from being broken due to vibration during operation.

[0030] For details, please refer to Figures 2 to 4 The floating compensation connector includes a housing 1, a base 2, an elastic element 3, and a contact element 4, all made of conductive material. The housing 1 is used to connect to an external object A, and has a floating hole 10 and a step 11. The step 11 extends outward from the first outer peripheral wall 12a of the housing 1. The base 2 is disposed within the floating hole 10, and a first gap X1 exists between the second outer peripheral wall 22 of the base 2 and the first inner peripheral wall 12b forming the floating hole 10, allowing the base 2 to float within the floating hole 10 to avoid inaccurate docking caused by positional errors between object B and object A.

[0031] Optionally, a limiting block 13 protrudes from the housing 1, which engages with the object A and is arranged in a ring shape. When the housing 1 is connected to the object A, the limiting block 13 is accommodated inside the object A and engages with the object A to prevent the housing 1 from detaching from the object A. In addition, the housing 1 is also provided with knurled lines 14 to increase the friction between the housing 1 and the object A.

[0032] Furthermore, the substrate 2 is provided with a channel 20 and a flange structure 21. A contact 4 electrically connected to the substrate 2 is provided within the channel 20 for connecting an external object B. The flange structure 21 extends outward from the second outer peripheral wall 22, and a cavity 210 is formed within the flange structure 21. The step 11 is accommodated within the cavity 210, and the flange structure 21 includes a first flange 211 and a third flange 213 located on both sides of the step 11, with one side of the step 11 abutting against the first flange 211. One side of the elastic member 3 abuts against the third flange 213, and the other side abuts against the step 11.

[0033] Meanwhile, it should be understood that the elastic element 3 is always in a state of stored force. Therefore, the elastic element 3 always supports the step 11, so that the step 11 and the first flange 211 are always in contact. Ultimately, the base 2 and the shell 1 are always in contact, avoiding the relative displacement between the base 2 and the shell 1 caused by vibration during operation, which would cause the object A and object B to break apart.

[0034] Preferably, the elastic element 3 is a wave spring. Under the same load conditions, the total height and working height of the wave spring are significantly lower than those of the traditional round wire spring, which can reduce the axial space occupation by 50% and facilitate the lightweight design of the connector.

[0035] Key reference Figure 3The flange structure 21 is integrally formed with the base 2 and also includes a second flange 212. The two ends of the second flange 212 are fixedly connected to the first flange 211 and the third flange 213, respectively. The first flange 211, the second flange 212, and the third flange 213 enclose to form the cavity 210 described above. There is a second gap X2 between the second flange 212 and the step 11, and there is a third gap X3 between the edge of the third flange 213 and the shell 1. The widths of the second gap X2 and the third gap X3 are both greater than or equal to the width of the first gap X1, so as to avoid affecting the floating of the base 2 within the floating hole 10.

[0036] Preferably, the widths of the second gap X2 and the third gap X3 are the same as the width of the first gap X1, so as to ensure that the overall structure of the floating compensation connector is compact and avoids occupying too much space.

[0037] Optionally, the first flange 211 is arranged perpendicularly to the second outer peripheral wall 22, and the third flange 213 is arranged parallel to the first flange 211, so as to further limit the relative displacement of the base 2 and the shell 1 in the axial direction.

[0038] In this embodiment, the first upper surface 211a of the first flange 211 is coplanar with the second upper surface 2a of the base 2. That is, the flange structure 21 is formed on one end of the base 2 to further reduce the size of the base 2, making the overall connector structure more compact. At the same time, the thickness of the second flange 212 is equal to the thickness of the first flange 211 and the third flange 213, ensuring structural balance and enhancing overall stability.

[0039] Further reference Figure 4 At least one protrusion 110 is provided on the side of the step 11 facing the first flange 211, and the protrusion 110 abuts against the first flange 211. By setting the protrusion 110 to abut against the first flange 211, this utility model ensures that the step 11 and the first flange 211 are always in contact, while reducing the contact area between the step 11 and the first flange 211, thereby reducing wear when the base 2 and the housing 1 slide relative to each other, and extending the service life of the connector.

[0040] Preferably, there are two protrusions 110, which are arranged in concentric circles and formed at the two edges of the step 11.

[0041] In addition, in this embodiment, the protrusion 110 is annular and coaxially arranged with the floating hole 10 to ensure the stability of the contact force between the step 11 and the first flange 211.

[0042] The present invention provides a floating compensation connector, which forms a flange structure 21 on the base 2 and a step 11 on the housing 1. The step 11 is disposed in the cavity 210 within the flange structure 21, and an elastic element 3 is provided so that the step 11 and the first flange 211 always abut against each other. This allows the present invention to perform radial floating compensation to avoid the positional error between object B and object A and the positional error caused by other factors. At the same time, it can also avoid the disconnection between object A and object B caused by vibration during operation.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
