[0038] The present invention provides a floating board-to-board connector and a female socket thereof.

[0039] In the embodiment of the present invention, Figures 1 to 3The floating board-to-board connector female connector 100 includes a base 110 and a movable base 120. The base 110 defines a movable cavity with open ends; the movable base 120 is movably disposed within the movable cavity. The movable base 120 defines an insertion slot 121, within which a mounting portion 130 is disposed. At least one side of the mounting portion 130 defines a receiving groove 131. The receiving groove 131 includes a notch communicating with the insertion slot 121 and a groove wall opposing the notch. The groove wall is recessed along the thickness of the mounting portion 130 to form a core thickening groove 132.

[0040] Specifically, the floating board-to-board connector mainly includes a male socket 200 and a female socket 100 (also referred to as a male-end connector and a female-end connector), and the male socket 200 and the female socket 100 are respectively installed on different circuit boards. The male socket 200 is provided with a plug-in terminal for transmitting signals, and the female socket 100 is provided with a signal terminal 140 for transmitting signals, and the plug-in terminal and the signal terminal 140 are respectively electrically connected to different circuit boards. The male socket 200 is provided with a plug-in end for installing the plug-in terminal, and the female socket 100 is provided with a plug-in slot 121, and the plug-in slot 121 is provided with a mounting portion 130. A portion of the signal terminal 140 is installed on the mounting portion 130, and then through the plug-in fit between the plug-in end and the plug-in slot 121, the plug-in terminal of the male socket 200 and the signal terminal 140 of the female socket 100 are connected to achieve electrical connection between the two connected circuit boards.

[0041] In addition, in the floating board-to-board connector, a floating structure is provided in the female socket 100, which enables the two circuit boards to move relative to each other while maintaining electrical connection, thereby eliminating the misalignment of the circuit boards during the assembly process and reducing the force between the connector and the circuit boards.

[0042] The signal terminals 140 of the female connector 100 are typically made of resilient metal sheets or strips. One end of each signal terminal 140 features a soldering section for electrical connection to solder points or connectors on a circuit board. The other end features a contact section, which contacts the terminals on the other connector (male or female) when the male connector 200 and female connector 100 are mated, thereby ensuring signal continuity within the floating board-to-board connector.

[0043] In this embodiment, the signal terminals 140 mounted on the receptacle 100 (hereinafter referred to as the receptacle 100) of a floating board-to-board connector not only provide electrical conductivity but also serve as a floating mechanism for the receptacle 100. Specifically, the signal terminals 140 include a soldering section mounted on the base 110, a contact section mounted on the mounting portion 130, and a connecting section connecting the contact section and the soldering section. The receptacle 100 primarily comprises a base 110, a movable seat 120, and the signal terminals 140. The base 110 has a generally rectangular parallelepiped structure, although other shapes, such as a cube or cylinder, are also possible, without specific limitation. The base 110 has an internal active cavity. In this embodiment, the active cavity extends through the base 110 along its height, with the upper and lower sides of the active cavity being open. The base 110 is generally annular in shape, with the space enclosed by the annular portion forming the active cavity. Such an arrangement facilitates the installation of the movable seat 120 and the signal terminal 140 , thereby improving assembly efficiency.

[0044] When the female base 100 is mounted on a circuit board, the base 110 is fixedly connected to the circuit board. In this embodiment, connecting portions are provided at both ends of the base 110 in the longitudinal direction, and the base 110 is fixedly connected to the circuit board via the connecting portions. In other embodiments, to facilitate positioning of the base 110 on the circuit board, the bottom surface of the base 110 is further provided with positioning posts, and corresponding positioning holes are provided on the circuit board. During installation, the base 110 is positioned by inserting the positioning posts into the positioning holes, and then the base 110 is fixedly connected to the circuit board via the connecting portions.

[0045] The movable seat 120 is movably arranged in the movable cavity and is provided with a plug-in slot 121 for plugging with the male socket 200. A mounting portion 130 is provided in the plug-in slot 121. The mounting portion 130 is provided with a receiving slot 131 for accommodating the contact segment. The contact segment of the signal terminal 140 is installed in the receiving slot 131. It should be noted that when the movable seat 120 is movably arranged in the movable cavity, the entire movable seat 120 can be located in the movable cavity to make the structure of the entire female socket 100 more compact. Alternatively, the lower half of the movable seat 120 can be located in the movable cavity, and the upper half can extend out of the movable cavity, so that the plug-in process between the female socket 100 and the male socket 200 is easy to observe, thereby improving the convenience and accuracy of the plug-in between the male socket 200 and the female socket 100.

[0046] The movable seat 120 generally has a shape that matches the base 110 and the movable cavity. For example, in this embodiment, the movable seat 120 and the base 110 are both rectangular parallelepiped structures, and the movable seat 120 extends along the length of the base 110. It can be understood that the rectangular movable seat 120 and base 110 can accommodate more signal terminals 140 along the length direction, thereby improving the conductive performance of the connector.

[0047] Please combine Figure 3 The contact section and fixed section of the signal terminal 140 are connected by a connecting section. The connecting section of the signal terminal 140 is generally U-shaped and is located between the inner wall of the base 110 and the outer wall of the movable base 120. Specifically, when the movable base 120 moves relative to the base 110, the connecting section elastically deforms, thereby allowing the movable base 120 to move relative to the base 110. In other words, the connecting section of the signal terminal 140 is a key component that enables the movable base 120 to move.

[0048] It is understandable that the connector female seat 100 is generally formed by injection molding, and the movable seat 120 and the base 110 are respectively molded by injection molding. Then, the signal terminal 140 is assembled to the movable seat 120 and the base 110, thereby connecting the movable seat 120 and the base 110. During injection molding, the mounting portion 130 and the movable seat 120 are generally molded as one piece. In order to form the receiving groove 131 located on the side wall of the mounting portion 130, a core is usually required. In order to be able to demold, the core is generally in the form of a cantilever beam. However, since the receiving groove 131 is shallow, the core will be correspondingly thinner. After the molten plastic enters the cavity, it will have a certain impact on the core, which can easily cause the core to deform or skew, and thus cause the female seat 100 to fail to mold. Please combine Figures 5 to 7 To avoid this, the present invention provides a core thickening groove 132 recessed in the wall of the accommodating groove 131, thereby thickening the core in the mold, thereby increasing the rigidity and stability of the core and preventing deformation. Providing the core thickening groove 132 can also reduce the overall weight of the base 100, while saving materials used in injection molding production.

[0049] It should be noted that only a portion of the wall of the accommodating groove 131 is recessed to form the core thickening groove 132. The wall of the accommodating groove 131 needs to leave space for contact with the contact segment. Therefore, the notch area of ​​the core thickening groove 132 is smaller than the wall area of ​​the accommodating groove 131. Of course, the contact segment can also be provided with a protruding fixing segment that extends into the core thickening groove 132 to secure the signal terminal 140.

[0050] The floating board-to-board connector female connector 100 of the present invention includes a base 110 and a movable base 120. The base 110 is provided with a movable cavity with both ends open; the movable base 120 is movably disposed in the movable cavity. The movable base 120 is provided with a plug-in slot 121, and a mounting portion 130 is disposed within the plug-in slot 121. At least one side of the mounting portion 130 is provided with a receiving groove 131. The receiving groove 131 has a notch communicating with the plug-in slot 121 and a groove wall opposite the notch. The groove wall is recessed along the thickness direction of the mounting portion 130 to form a core thickening groove 132. Thus, by providing the core thickening groove 132, on the one hand, the thickness of the core used to manufacture the female connector 100 can be increased, thereby increasing the rigidity of the core, preventing deformation or skewness of the core, and thereby increasing the yield rate of the female connector 100. On the other hand, the overall weight of the female connector 100 can be reduced, and the material used to manufacture the female connector 100 can be saved.

[0051] In one embodiment, the accommodating grooves 131 are provided on both sides of the mounting portion 130 , and the groove wall of each accommodating groove 131 is recessed to form a core thickening groove 132 .

[0052] Specifically, the mounting portion 130 is roughly rectangular, with accommodating grooves 131 provided on either side of the mounting portion 130. This allows the mounting portion 130 to accommodate more signal terminals 140, thereby improving the connector's signal transmission capability. The walls of each accommodating groove 131 are recessed to form core thickening grooves 132, ensuring the rigidity of each core in the mold, thereby ensuring the production quality of the female connector 100 and improving the yield rate.

[0053] In one embodiment, a positioning groove 134 is provided on the top of the mounting portion 130 , and two sides of the positioning groove 134 are respectively connected to the core thickening groove 132 .

[0054] It should be noted that the mounting portion 130 is generally provided with a large number of receiving grooves 131, so the number of cores in the mold is also large. In the mold, since the core can only be demolded in the form of a cantilever beam, and only one side of the core is in contact with the mold forming the plug-in slot 121, the core may still be deformed during the use of the mold (i.e., the core of the receiving groove 131 moves in the direction of the mold away from the plug-in slot 121), resulting in the receiving groove 131 produced by the mold having poor straightness, which may cause the connection between the male connector 200 plug-in terminal and the female connector 100 signal terminal 140 to be unstable, affecting the transmission of the signal. In order to avoid this situation, a positioning block is protruded on the template of the mounting portion 130, and the core is in contact with the positioning block, so that the core is positioned under the joint action of the positioning block and the mold for forming the plug-in slot 121, thereby improving the stability of the core. Since both sides of the mounting portion 130 are provided with a receiving groove 131, positioning blocks are arranged in the middle of the cores of the receiving grooves 131 on both sides of the mounting portion 130, so that the cores on both sides can abut against the same positioning block, thereby saving mold production costs. Due to the presence of the positioning blocks, a positioning groove 134 is formed on the top of the mounting portion 130. This positioning groove 134 also has the effect of reducing the overall weight of the female seat 100 and saving material. Since the cores on both sides abut against the two sides of the positioning blocks, the two sides of the positioning groove 134 are connected to the core thickening groove 132.

[0055] In one embodiment, the ratio of the depth of the positioning groove 134 to the length of the core thickening groove 132 is greater than or equal to 0.15 and less than or equal to 0.5.

[0056] Specifically, see Figure 5 and Figure 6 If the ratio of the depth of the positioning groove 134 to the length of the core thickening groove 132 is less than 0.15, the positioning groove 134 will be shallow, that is, the portion of the positioning block on the mold that abuts the core is small, or even the core cannot abut against the positioning block, and cannot play a role in positioning and reinforcing the core, thereby causing the core to deform during the injection molding process. If the ratio of the depth of the positioning groove 134 to the length of the core thickening groove 132 is greater than 0.5, the positioning block of the mold will be too long, and the positioning groove 134 on the mounting portion 130 will be too deep. On the one hand, this may cause the structural strength of the mounting portion 130 to be insufficient, and then cause the mounting portion 130 to be easily damaged during the plug-in process. On the other hand, an overly long positioning block may make it difficult for the positioning block to disengage from the positioning groove 134 during the demoulding process, resulting in damage to the female seat 100 and even causing the mold to be scrapped.

[0057] In one embodiment, the female socket 100 of the board-to-board connector also includes a signal terminal 140, which includes a welding section 141, a contact section 142, and a connecting section 143 connecting the welding section 141 and the contact section 142. The welding section 141 is used to be welded to the circuit board, and the connecting section 143 is arranged in the movable cavity. One end of the contact section 142 is connected to the connecting section 143, and the other end extends into the plug-in slot 121 and is accommodated in the accommodating slot 131; the plug-in slot 121 includes a first sub-groove 121a located in the movable seat 120 and a second sub-groove 121b located at the bottom of the movable seat 120; wherein, the contact section 142 is provided with a fixing portion 145 on the peripheral side close to the side of the connecting section 143, and the groove wall of the second sub-groove 121b is provided with a mating portion for inserting the fixing portion 145.

[0058] Furthermore, please combine Figure 6 The first sub-groove 121a is used to accommodate the plug-in terminal of the male socket 200, so that the plug-in terminal can be plugged into the first sub-groove 121a, thereby enabling the plug-in terminal to be electrically connected to the contact section of the signal terminal 140 on the mounting portion 130. The second sub-groove 121b is used to install and accommodate the mounting portion 130. One end of the mounting portion 130 is fixedly mounted in the second sub-groove 121b, and the other end of the mounting portion 130 is located in the first sub-groove 121a, so that the contact section on the mounting portion 130 can be exposed in the first sub-groove 121a, thereby connecting with the plug-in terminal of the male socket 200. It is worth mentioning that in the related art, the fixing portion 145 is provided on both sides of the mounting portion 130 in the longitudinal direction of the contact section 142, that is, the fixing portion 145 is interference-fitted with the groove wall of the accommodating groove 131 to secure the signal terminal 140. Because multiple signal terminals 140 are arranged along the length of the mounting portion 130, and each signal terminal 140 is interference-connected with the receiving groove 131, the interference effect on the receiving groove 131 caused by the interference connection of the signal terminals 140 will accumulate along the length of the mounting portion 130, which may cause the mounting portion 130 to be broken. To avoid this, the fixing portion 145 is arranged on the side of the contact section 142 facing the groove wall of the second sub-groove 121b. This prevents the accumulation of the distending force generated by the interference connection of the signal terminals 140, thereby preventing the movable seat 120 from being distended. Optionally, a mating portion for the fixing portion 145 to be inserted into the side wall of the second sub-groove 121b is provided. The provision of the mating portion can not only make the fixation of the signal terminals 140 more stable, but also further prevent the movable seat 120 from being distended, thereby increasing the reliability of the female socket 100.

[0059] In one embodiment, a limiting protrusion 144 is provided at one end of the contact section 142 away from the connecting section 143, and a limiting groove 133 connected to the accommodating groove 131 is provided on one side of the accommodating groove 131 close to the top of the mounting portion 130, and the limiting groove 133 is used for inserting the limiting protrusion 144.

[0060] It is understood that the contact section of the signal terminal 140 is placed in the receiving groove 131. When the male socket 200 is plugged into the movable socket 120, the plug-in terminal of the male socket 200 needs to abut against the contact section, thereby conducting the signal terminal 140. Due to the small size and long contact section in the receiving groove 131, the insufficient rigidity makes it easy for the contact section to fall out of the receiving groove 131. This in turn causes the contact section to have poor straightness along the length of the mounting portion 130, thus affecting the plugging of the male socket 200 and the female socket 100, and may cause unstable plugging or even damage the connector.

[0061] To avoid this problem, a retaining groove 133 is provided on the mounting portion 130, and a retaining protrusion is provided on the side of the contact section of the signal terminal 140 facing away from the connecting section. By inserting the retaining protrusion into the retaining groove 133, the contact section is fixed in place, ensuring that the contact section is stably positioned within the accommodating groove 131, facilitating the connection between the male connector 200 and the female connector 100. Furthermore, the retaining protrusion can be semicircular or conical in shape, without specific limitation.

[0062] In one embodiment, the plurality of receiving slots 131 are spaced apart along the length of the mounting portion 130. Specifically, when a connector transmits signals, multiple lines typically transmit information simultaneously. Therefore, by spacing the receiving slots 131 along the length of the mounting portion 130, multiple signal terminals 140 for transmitting signals can be installed on the female connector 100, thereby improving the connector's signal transmission capability.

[0063] In one embodiment, the bottom of the mounting portion 130 has an opening that communicates with the receiving groove 131. The side of the receiving groove 131 near the opening is flared. It is worth noting that both the core thickening groove 132 and the side of the receiving groove 131 near the bottom of the mounting portion 130 are provided with openings for assembling the signal terminal 140. During assembly, the signal terminal 140 is inserted through the opening into the receiving groove 131. The end of the receiving groove 131 near the bottom of the mounting portion 130, where the opening is located, is flared. On the one hand, since the signal terminal 140 is inserted into the receiving groove 131 through the opening, the flared design of the receiving groove 131 serves as a guide for the insertion of the signal terminal 140 from the opening into the receiving groove 131. On the other hand, the flared design of the receiving groove 131 facilitates demolding of the core.

[0064] In one embodiment, the side wall of the core thickening groove 132 close to the top of the mounting portion 130 is inclined in the direction from the core thickening groove 132 toward the accommodating groove 131 toward the top of the mounting portion 130. Figures 5 to 7 The inclined sidewalls of the core thickening groove 132 guide the insertion of the signal terminal 140's retaining protrusion into the retaining groove 133 during installation. Furthermore, the inclined sidewalls facilitate the removal of the core from the accommodating groove 131 and the core thickening groove 132 during demolding, avoiding the difficulty in demolding caused by the right-angled connection between the accommodating groove 131 and the core thickening groove 132, as well as potential damage to the right-angled groove walls during demolding.

[0065] The floating board-to-board connector proposed in the present invention includes a male socket 200 and a female socket 100. The specific structure of the female socket 100 refers to the above embodiment. Since the floating board-to-board connector adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
