As a result, the reliability of normal docking of the connector is low, and the interface is prone to premature wear. The position accuracy of the connector is required to be high during assembly. Utility Model Content
[0003] The utility model aims to provide a docking mechanism and a docking device, which have the advantages of strong economy, improving the reliability of normal docking of connectors, ensuring the consistency of initial positions of connectors, reducing connector wear and connector position accuracy requirements, etc.

[0006] Furthermore, the limiting member further has a second limiting surface, the second limiting surface and the first limiting surface are spaced apart along the axial direction of the limiting member, and the second limiting surface abuts against the end surface of the fixing seat facing the connector.
[0007] Furthermore, the elastic member is annularly sleeved outside the limiting member.

[0009] Furthermore, the limiting member is provided with a groove for accommodating the elastic member, and the elastic member protrudes out of the groove away from the outer ring of the limiting member.
[0010] Further, the height dimension of the elastic member along the axial direction of the limiting member is smaller than the height dimension of the groove along the axial direction of the limiting member.
[0011] Further, the width of the annular gap is not greater than 0.3 mm.
[0012] Further, the interval between the first limiting surface and the surface of the connector facing away from the fixed seat is 0.07 - 0.13 mm.

[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0031] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not used to limit the present utility model.
[0032] An embodiment of the first aspect of the present utility model is to provide a docking mechanism, as Figures 1 to 5 shown, including a connector 1, a fixed seat 2, a limiting member 3, and an elastic member 4. The connector 1 is provided at one end of the fixed seat 2. The connector 1 is provided with a through hole 11. One end of the limiting member 3 passes through the through hole 11 and is connected to the fixed seat 2. There is an annular gap 5 between the inner surface of the through hole 11 and the side surface of the limiting member 3 passing through the through hole 11. The elastic member 4 is clamped between the inner surface of the through hole 11 and the side surface of the limiting member 3 passing through the through hole 11. The other end of the limiting member 3 has a boss, and a first limiting surface is provided on the side of the boss facing the connector 1. The first limiting surface 31 is spaced from the surface of the connector 1 facing away from the fixed seat 2, so that the connector 1 has a floating amount along the axial direction of the connector 1.
[0033] When using the above docking mechanism to dock with a probe station, since there is an annular gap 5 between the side surface of the limiting member 3 and the inner surface of the through hole 11, and the elastic member 4 is clamped between the side surface of the limiting member 3 and the inner surface of the through hole 11, and the elastic member 4 is in contact with both the limiting member 3 and the through hole 11, the connector 1 can float relative to the limiting member 3 in the radial direction of the limiting member 3, improving the reliability of the normal docking of the connector 1, reducing the wear of the connector 1, and at the same time, after docking, under the elastic force of the elastic member 4, the limiting member 3 can automatically return to its position and be centered.
[0034] It can be understood that the above floating can be regarded as floating in the X and Y directions.
[0035] In addition, since the first limiting surface 31 on the limiting member 3 is spaced from the surface of the connector 1 facing away from the fixed seat 2, the connector 1 has a certain floating amount along the axial direction of the limiting member 3, avoiding the connector 1 from being stuck and unable to float, and further improving the reliability of the normal docking of the connector 1.
[0036] It can be understood that the above floating can be regarded as floating in the Z direction.
[0037] In an alternative embodiment, a buffer pad may be provided on the first limiting surface 31. The buffer pad can prevent the first limiting surface 31 from making hard contact with the connector 1, thereby protecting both of them.
[0038] After docking is completed, under the elastic force of the elastic member 4, the connector 1 can automatically return to the centered position, ensuring the consistency of the initial position of the connector 1 and preventing premature wear of the interface due to the connector 1 not being in the initial position during the next docking.
[0039] In addition, compared with a floating mechanism including a spring, the docking mechanism provided in the above embodiment also has the advantages of simple structure, not requiring a large amount of space, strong economy, and being easy to promote and use.
[0040] Specifically, a connection hole may be provided on the fixed seat 2, and a through hole 11 may be provided on the connector 1. One end of the limiting member 3 passes through the through hole 11 and is limited within the connection hole of the fixed seat 2, and an annular gap 5 is formed between the portion of the limiting member 3 within the through hole 11 and the inner wall of the through hole 11.
[0041] The limiting member 3 is fixedly connected to the fixed seat 2, and there are various ways of fixed connection. For example, the limiting member 3 and the fixed seat 2 are in interference fit, or the limiting member 3 and the fixed seat 2 are threadedly connected, or the limiting member 3 and the fixed seat 2 are snap-connected, and so on.
[0042] In a preferred embodiment, the limiting member 3 is threadedly connected to the fixed seat 2.
[0043] In a preferred embodiment, the limiting member 3 is a pin.
[0044] In an alternative embodiment, as Figure 7 shown, the limiting member 3 further has a second limiting surface 32. The second limiting surface 32 and the first limiting surface 31 are spaced apart along the axial direction of the limiting member 3, and the second limiting surface 32 abuts against the end face of the fixed seat 2 facing the connector 1.
[0045] The setting of the second limiting surface 32 can limit the distance that the limiting member 3 extends into the fixed seat 2, thereby playing a role in limiting the position of the limiting member 3. Especially when the limiting member 3 is threadedly connected to the fixed seat 2, the abutment of the second limiting surface 32 against the end face of the fixed seat 2 facing the connector 1 can make the limiting member 3 more firmly connected to the fixed seat 2, and the limiting member 3 is not easily loosened.
[0046] It can be understood that the above elastic member 4 can achieve the centering of the connector 1 after docking by utilizing its own elasticity. After centering, the minimum floating amount of the connector 1 during connection can be ensured, thereby reducing wear and improving the docking life of the connector 1; in an alternative embodiment, the elastic member 4 does not need to be wound around the limiting member 3 for one week, and the elastic member 4 may include a plurality of elastic blocks, and the plurality of elastic blocks are evenly spaced around the axis of the limiting member 3.
[0047] Of course, in an optional implementation, the elastic member 4 may also include an elastic ring sleeved on the outside of the limiting member 3 .
[0048] In a preferred embodiment, in order to facilitate the installation of the elastic member 4 , the elastic member 4 is annularly sleeved outside the limiting member 3 .
[0049] The material of the elastic member 4 may be, but is not limited to, rubber.
[0050] In an optional embodiment, if Figure 5 As shown, the elastic member 4 is configured in plurality, and the plurality of elastic members 4 are distributed at intervals along the axial direction of the limiting member 3 .
[0051] In the above embodiment, the elastic member 4 is configured as a plurality, which can reduce the extrusion force on each elastic member 4 during docking, thereby extending the life of the elastic member 4, compared with configuring it as one.
[0052] In a preferred embodiment, Figure 5 As shown, the elastic member 4 is configured in two.
[0053] In an optional embodiment, if Figure 5 As shown, in order to ensure that the position of the elastic member 4 relative to the limiting member 3 is more stable, the limiting member 3 is provided with a groove 33 for accommodating the elastic member 4. The groove 33 can limit the elastic member 4 along the axial direction of the limiting member 3. The elastic member 4 protrudes from the groove 33 away from the outer ring of the limiting member 3, so that the part of the elastic member 4 protruding from the groove 33 can extend into the annular gap 5. After docking, the connector 1 can automatically return to the center under the elastic force of the elastic member 4.
[0054] When the elastic member 4 is annular, it can be understood that the groove 33 is also annular.
[0055] In an optional embodiment, if Figure 6 As shown, the height dimension d2 of the elastic member 4 along the axial direction of the stopper 3 is smaller than the height dimension d1 of the groove 33 along the axial direction of the stopper 3. It can be understood that when the elastic member 4 is subjected to an external force, in addition to being deformed along the radial direction of the stopper 3, it can also extend along the axial direction of the stopper 3, that is, the arrangement of the groove 33 leaves a deformation space for the deformation of the elastic member 4 in the axial direction.
[0056] The above arrangement can reduce the friction between the limit member 3, the elastic member 4 and the connector 1 when the connector 1 floats along the axial direction of the limit member 3. At the same time, the elastic member 4 can also have a certain floating amount relative to the groove 33, thereby facilitating the position adjustment of the connector 1 in the above direction.
[0057] Let a plane passing through the axis of the limiting member 3 cut the limiting member 3 and the groove 33. The cross-section of the elastic member 4 can be circular or elliptical, and the cross-section of the groove 33 can be rectangular or semi-elliptical. Of course, the cross-sectional shapes of the elastic member 4 and the groove 33 are not limited to the above examples.
[0058] The sum of the depth dimension of the groove 33 in the radial direction of the limiting member 3 and the width dimension of the annular gap 5 in the radial direction of the limiting member 3 can be equal to the thickness dimension of the elastic member 4 in the above-mentioned radial direction. In this way, the elastic member 4 can just be clamped between the connector 1 and the limiting member 3, ensuring the centering of the connector 1 after docking.
[0059] Of course, within the allowable error of centering, the sum of the depth dimension of the groove 33 in the radial direction of the limiting member 3 and the width dimension of the annular gap 5 in the radial direction of the limiting member 3 can also be slightly larger than the thickness dimension of the elastic member 4 in the above-mentioned radial direction.
[0060] In an alternative embodiment, the width of the annular gap 5 can be less than 1 mm. Specifically, the width of the annular gap 5 can be 0.1 mm, 0.3 mm, 0.5 mm, 0.8 mm or 1 mm.
[0061] In a preferred embodiment, the width of the annular gap 5 is not greater than 0.3 mm, such as 0.1 mm, 0.2 mm or 0.3 mm.
[0062] It can be understood that the width of the above-mentioned annular gap 5 is not 0.
[0063] In a more preferred embodiment, the width of the annular gap 5 is 0.25 mm.
[0064] The above setting can make the floating range of the connector 1 in the radial direction of the limiting member 3 be ±0.25 mm, improving the reliability of the normal docking of the connector 1.
[0065] In an alternative embodiment, the interval between the first limiting surface 31 and the surface of the connector 1 facing away from the fixed seat 2 is 0.07 - 1 mm. Specifically, the above interval can be 0.07 mm, 0.1 mm, 0.5 mm, 0.8 mm or 1 mm.
[0066] In a preferred embodiment, the interval between the first limiting surface 31 and the surface of the connector 1 facing away from the fixed seat 2 is 0.07 - 0.13 mm, such as 0.07 mm, 0.1 mm or 0.13 mm.
[0067] In a more preferred embodiment, the interval between the first limiting surface 31 and the surface of the connector 1 facing away from the fixed seat 2 is 0.1 mm.
[0068] The above setting can make the floating range of the connector 1 in the axial direction of the limiting member 3 be 0.1 mm, improving the reliability of the normal docking of the connector 1.
[0069] In an alternative embodiment, as Figure 2 shown, both ends of the connector 1 are connected to the fixed seat 2 through a limiting member 3 respectively, so as to realize the installation and positioning of the connector 1.
[0070] An embodiment of the second aspect of the present utility model lies in providing a docking device, and the docking device provided by the embodiment of the second aspect of the present utility model includes the above docking mechanism.
[0071] The docking device provided by the second aspect of the present utility model has the docking mechanism provided by the embodiment of the first aspect of the present utility model, and thus has all the beneficial effects of the docking mechanism provided by the embodiment of the first aspect of the present utility model.
[0072] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
