[0001] This utility model relates to the field of connector technology, and in particular to a floating terminal and an automatic calibration connector. Background Technology

[0002] Connectors typically consist of a male terminal and a female terminal, which are connected to conduct current or signals. Currently, most connectors are assembled using automated assembly machines for positioning and mating. However, misalignment of the male and female terminals can easily lead to misalignment or damage. In addition, environmental vibrations can cause micro-movements in the connector and socket, which can damage the contacts and affect contact stability and reliability. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a floating terminal, one end of which is fixedly connected to the base and the other end supports the floating body, so that the floating part is sandwiched between the floating body and the base to form a floating gap. The floating body can move within the floating gap through the elastic support of the floating part.

[0004] Another objective of this invention is to provide a connector that supports the spatial offset of the floating body through floating terminals. During mating, it can automatically correct the offset to ensure smooth insertion of the pins and meet assembly error requirements. At the same time, it can counteract the micro-movement of the connector puller caused by vibration, thereby reducing the stress on the connector and PCB. It can also reduce wear on the contact points and improve the contact stability and reliability of the connector during mating and use.

[0010] Furthermore, the main body fixing part is also provided with a second connecting part for guiding the second plug-in part and the third plug-in part. The second connecting part and the first connecting part are located on the same side of the pin, so that the third plug-in part and the first plug-in part abut against the same side wall of the pin.

[0011] Furthermore, the first plug-in portion is provided with a first contact, and the third plug-in portion is provided with a third contact. The distance between the first contact and the second plug-in portion is smaller than the distance between the third contact and the second plug-in portion.

[0036] Please see Figure 1-5 This application provides a floating terminal, one end of which is fixed to a base 20, and the other end is floatingly connected to a floating body 30. The floating terminal 10 includes a base fixing part 12, a body fixing part 14, and a floating part 13. The base fixing part 12 is used to fix to the base 20, the body fixing part 14 is used to fix to the floating body 30, and the floating part 13 is in the shape of a reciprocating curve. Its two ends are respectively connected to the base fixing part 12 and the body fixing part 14, so that a floating gap is formed between the base 20 and the floating body 30, thereby realizing the displacement of the floating body 30 within the floating gap.

[0037] The floating terminal 10 provided in this embodiment is fixedly connected to the base 20 at one end and supports the floating body 30 at the other end, so that the floating part 13 is sandwiched between the floating body 30 and the base 20 to form a floating gap. The floating body 30 can move within the floating gap through the elastic support of the floating part 13. When inserting, it can automatically correct so that the pin 200 can be inserted smoothly and meet the assembly error. At the same time, it can offset the micro-movement caused by vibration to reduce the force on the terminal and PCB 300. It can also reduce the wear of the contact point between the pin 200 and the floating terminal 10 and improve the stability and reliability of the floating terminal 10.

[0038] Please see Figure 2-4Furthermore, in some embodiments, the main body fixing part 14 includes a first insertion part 141 and a second insertion part 143 disposed opposite to each other; the first insertion part 141 and the second insertion part 143 are fixed in the pin hole 31 of the floating main body 30, so that the opposite two end faces of the pin 200 can respectively abut against the first insertion part 141 and the second insertion part 143, thereby further improving the stability of the contact between the pin 200 and the floating terminal 10 and improving the reliability of the product.

[0039] Furthermore, the first insertion part 141 is provided with a first anti-retraction part 1412; the second insertion part 143 is provided with a second anti-retraction part 1431. The first anti-retraction part 1412 and the second anti-retraction part 1431 are respectively fixed to the pin hole 31 of the floating body 30, so as to fix the first insertion part 141 and the second insertion part 143 to the two opposite inner wall surfaces of the pin hole 31, so as to prevent the first insertion part 141 and the second insertion part 143 from being loosened from the floating body 30.

[0040] It is understood that in this embodiment, the first stop portion 1412 and the second stop portion 1431 are continuous barbed structures. Correspondingly, slots are cut into the two opposing inner walls of the pin hole 31 for the insertion of the first insertion portion 141 and the second insertion portion 143. The barbs on both sides interfere with the slots to achieve a fixed connection between the first insertion portion 141 and the second insertion portion 143 and the floating body 30. In other embodiments, the first stop portion 1412 and the second stop portion 1431 can also be configured with other structures capable of achieving a fixed connection between the first insertion portion 141 and the second insertion portion 143 and the floating body 30, and are not limited thereto.

[0041] Furthermore, in some embodiments, the main body fixing part 14 is also provided with a first connecting part 142, which is connected to the first plug-in part 141 and the second plug-in part 143 so that the first plug-in part 141 and the second plug-in part 143 are connected. At the same time, when the pin 200 is inserted, the first connecting part 142 can undergo elastic deformation to generate elastic force, so that the first plug-in part 141 and the second plug-in part are firmly abutted against the side wall of the pin 200, thereby improving the contact performance of the floating terminal 10.

[0042] Furthermore, in some embodiments, the main body fixing part 14 is also provided with a third insertion part 145, which is elastically connected to the second insertion part 143 and abuts against a different side wall of the pin 200, thereby improving the contact point between the floating terminal 10 and the pin 200 and improving the contact performance of the floating terminal 10.

[0043] Preferably, the third insertion portion 145 and the first insertion portion 141 are located on the same side of the pin, and abut against the same side wall of the pin 200. The main body fixing portion 14 is provided with a second connecting portion 144, which connects the second insertion portion 143 and the third insertion portion 145 to enable the second insertion portion 143 and the third insertion portion 145 to be connected.

[0044] Furthermore, in some embodiments, the first plug portion 141 has a first contact 1411 at its end, and the third plug portion 145 has a third contact 1451 for elastically abutting against the pin 200. In this configuration, when the first plug portion 141 and the third plug portion 145 are located on the same side of the pin 200, the third contact 1451 is a protrusion, and the first contact 1411 is a bent spring-arm contact to have a larger deformation space. The third plug portion 145 is recessed inside the first plug portion 141. At the same time, the distance between the first contact 1411 and the second plug portion 143 is smaller than the distance between the third contact 1451 and the second plug portion 143, so that the first plug portion 141 and the third plug portion 145 can simultaneously abut against the pin 200 without interfering with each other. When the pin 200 is inserted into the pin hole 31, one side wall of the pin 200 first contacts the first contact 1411 and squeezes the first contact 1411, causing the end of the first plug part 141 to elastically deform and move away from the second plug part 143. Then the side wall abuts against the third contact 1451 to achieve multi-contact contact, so as to ensure the stability of the floating terminal 10 during the floating connection process.

[0045] Furthermore, in some embodiments, the floating part 13 is wave-shaped, including at least one crest or trough, and its two ends are respectively provided with a first buffer part 131 and a second buffer part 132. The first buffer part 131 is connected to the base fixing part 12, and the second buffer part 132 is connected to the main body fixing part 14. Specifically, the first buffer part 131 and the second buffer part 132 can be arc-shaped, V-shaped, or U-shaped to separate the base fixing part 12 and the main body fixing part 14 located on both sides of the floating part 13 from the middle of the floating part 13, forming a floating gap; at the same time, the first buffer part 131 and the second buffer part 132 can provide support force for the floating body 30 to move on the XYZ axis.

[0046] Preferably, in this embodiment, the first buffer part 131 is set to an arc shape and the second buffer part 132 is set to a U shape, which can effectively isolate the base 20 and the floating body 30 in space and form a certain floating gap. Through the first buffer part 131 and the second buffer part 132, the floating body 30 can float in the floating gap after being squeezed, and can quickly reset after the squeezing is released.

[0047] Furthermore, in some embodiments, the floating terminal 10 is also provided with a welding part 11, which is located at the end of the floating terminal 10 near the base fixing part 12 and is used for welding onto the PCB 300.

[0048] This application embodiment also provides an automatic calibration connector, including: a base 20, a floating body 30, and a floating terminal 10; a base fixing part 12 is fixedly connected to the base 20; a body fixing part 14 is inserted into the floating body 30, and the floating body 30 is movably disposed inside the base 20 by the support of the floating terminal 10.

[0049] Please see Figure 1 and Figure 5 Furthermore, the base 20 is fixedly inserted into the PCB 300 via a positioning structure for positioning and soldering between the base 20 and the PCB 300. It is understood that this positioning structure can be a positioning structure with a positioning hole and a positioning post, or a snap-fit ​​positioning structure with a hook and a snap-fit; no limitation is made here. Further, the PCB 300 has a cutout 301, which is directly opposite the insertion end of the pin hole 31 of the floating body 30. The floating body 30 is buoyantly positioned at this cutout 301. When the pin 200 is inserted, the floating body 30 can automatically correct itself, allowing the pin 200 to be inserted smoothly and improving the insertion efficiency of the connector 100. In addition, when the external environment vibrates, this self-correcting connector 100, based on its floating body 30, can counteract the micro-movements of the connector 100 caused by vibration, reducing wear at the contact points between the floating terminal 10 and the pin 200, and improving the contact stability and reliability of the connector.

[0050] Furthermore, the automatic calibration connector 100 is also provided with a grounding plate 40, one end of which is fixed to the base 20 and the other end is soldered to the PCB 300, which will not be described in detail here.

[0051] The self-calibrating connector 100 with floating terminals 10 provided in this application embodiment allows the pin 200 to connect only to the floating body 30 when the pin 200 is inserted into the connector 100. The floating body 30 is subjected to the compressive force applied by the pin 200, and the floating part 13 of the floating terminal 10 automatically calibrates and adjusts the position of the floating body 30 to ensure smooth insertion of the pin 200 into the floating body 30. This self-calibrating floating structure enables the connector 100 to have excellent shock absorption, thereby improving the assembly stability of the connector 100. Furthermore, the self-calibrating connector 100 provided in this application embodiment only requires one set of floating terminals 10 to stably support the floating body. Compared to the traditional method of using two sets of symmetrically arranged floating terminals to support the floating body, the connector of this application embodiment is more conducive to miniaturization design of connector products, making it easier to apply to electronic products with high space requirements and thus offering greater applicability.

[0052] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:

[0053] (1) By fixing one end of the floating terminal to the base and supporting the floating body at the other end, the floating part is sandwiched between the floating body and the base to form a floating gap. The floating body can move within the floating gap through the elastic support of the floating part, thereby improving contact stability and reliability.

[0054] (2) By setting a main body fixing part with multiple contact points, the poor contact between the floating main body and the pin is avoided due to the displacement of the floating main body, thereby improving the contact stability between the floating terminal and the pin.

[0055] (3) By having a first plug and a second plug with opposite arrangement, the adhesion between the main body fixing part and the floating body can be better, and the main body fixing part can be effectively prevented from falling off the floating body;

[0056] (4) By setting a wave-shaped floating part, the floating body can be effectively supported to float and reset in the XYZ axis, so that the connector has excellent shock absorption effect and improves the assembly stability of the connector.

[0057] (5) Only one set of floating terminals is needed to stably support the floating body, which is conducive to the miniaturization design of connector products. The connector products can be more easily applied to some electronic products with high space requirements, and have stronger applicability.

[0058] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the 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 this utility model also intends to include these modifications and variations.
