Description

Technical Field

[0001] The utility model relates to the technical field of connector structures, in particular to a connector auxiliary separation structure and an OAM module. Background Art

[0002] Devices achieve signal transmission between different circuit boards or different components through connectors. The connection stability of the connectors is an important guarantee for the reliable operation of the devices. However, in some cases, the binding force of the connectors of the devices is too large. For example, the middle-layer connector (Mezzanine Connector) in the OAM (OCP Accelerator Module, OCP acceleration module) module, or there are multiple connectors on the circuit board, resulting in too large a total binding force after connection. When separating, the separation force required between the circuit boards or components is very large, which not only increases the difficulty of disassembly and maintenance, but also may cause the risk of damage to the circuit boards or components of the device. Especially in the case of uneven force application during the separation operation, it may cause physical damage to the connectors or surrounding structures.

[0003] Regarding the problem of excessive binding force of the middle-layer connector (Mezzanine Connector) in the OAM module, in the related art, a spiral spring is fixed by gluing on the module board. When the connectors are connected and combined, the spiral spring is compressed, and the elasticity of the spiral spring is used to reduce the separation force required for separating the connectors.

[0004] However, the above structure of the spiral spring has the following problems: (1) The glue joint surface for gluing on the module board requires precision machining by a machine tool to ensure flatness and roughness, thereby ensuring the reliability of glue bonding. There are defects such as high processing difficulty and high processing cost; (2) Special dispensing machines are required for applying glue to standardize the glue application amount and application path, and the equipment procurement cost is relatively high; (3) After the glue is applied, it needs to be baked and left standing in an oven, reducing production efficiency and further increasing production costs; (4) After the glue is dried, push-pull force tests need to be carried out to test the firmness of spring fixation, increasing the detection cost.

[0005] Therefore, the structure of the spiral spring has the problem of relatively high implementation cost, and the method of fixing the spiral spring by glue bonding has relatively low reliability. In addition, a large amount of heat is generated when the OAM module works, making the working environment temperature relatively high, which in turn leads to an accelerated aging rate of the glue, and the stability of fixing by glue bonding is relatively low. Summary of the Utility Model

Detailed implementation manners

[0028] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] The following combines Figures 1-5 to describe an auxiliary separation structure for a connector of the present utility model, including:

[0030] A bottom plate assembly 100, provided with at least one first connector 110;

[0031] A leaf spring 200 and a threaded connection structure 300, the threaded connection structure 300 is arranged on the bottom plate assembly 100, the leaf spring 200 is connected to the bottom plate assembly 100 through the threaded connection structure 300, the leaf spring 200 is provided with at least one elastic part 210, the elastic part 210 is located on one side of the first connector 110, and the elastic part 210 is used to be squeezed to provide an elastic separation force when the first connector 110 is connected.

[0032] The leaf spring 200 is connected to the bottom plate assembly 100 through the threaded connection structure 300, which can conveniently fix the leaf spring 200, and the threaded connection makes the connection between the leaf spring 200 and the bottom plate assembly 100 more stable, improving the reliability of the fixation of the leaf spring 200. By providing the elastic part 210 on the leaf spring 200, when the first connector 110 is connected, the elastic part 210 is squeezed. For example, when the first connector 110 is connected to the second connector 610 on the substrate assembly 600, the substrate assembly 600 squeezes the elastic part 210, and the elastic part 210 is squeezed and deformed to generate an elastic separation force, and the elastic separation force tends to separate the first connector 110 and the second connector 610.

[0033] In this way, the elastic separation force generated by the elastic part 210 can offset the binding force between the first connector 110 and the second connector 610, realizing a reduction in the separation force required when the first connector 110 is separated, which is beneficial to avoiding excessive separation force, making the disassembly and maintenance of the first connector 110 more convenient, preventing device damage caused by excessive required separation force, and improving the reliability of the structure.

[0034] Compared with the structure where a spiral spring is fixed by glue bonding, using the threaded connection structure 300 to realize the connection between the leaf spring 200 and the bottom plate assembly 100 can fix the leaf spring 200 more reliably, and realize threaded connection. For example, using structures such as screws and screw holes, the processing is simple and efficient, there are no special requirements for flatness and roughness, nor is there a need for special processing equipment and processes for baking and curing and checking the connection firmness by push-pull force, which is beneficial to reducing the production difficulty and production cost and improving the production efficiency.

[0035] In some embodiments of the present invention, the bottom plate assembly 100 may include devices such as a bottom plate body, a circuit board, and a reinforcing plate to form a multi-layer board structure.

[0036] It can be understood that a connector auxiliary separation structure provided by the present invention can be applied not only to the OAM module, but also to other different devices and modules with connectors.

[0037] Reference Figures 1 to 3In some embodiments of a connector auxiliary separation structure of the utility model, the leaf spring 200 includes a plane plate 220 and at least one extension end 230, the plane plate 220 is connected to the base plate assembly 100 through the threaded connection structure 300, the extension end 230 is arranged at the edge of the plane plate 220, the plane plate 220 and the extension end 230 are an integral structure, and the extension end 230 is provided with a bending portion 231 to enable the extension end 230 to partially detach from the plane where the plane plate 220 is located to form the elastic portion 210.

[0038] The leaf spring 200 is formed by a plane plate 220 and an extension end 230 of an integral structure. The plane plate 220 is connected to the bottom plate assembly 100 through a threaded connection structure 300. The plane plate 220 is convenient for being connected and fixed to the bottom plate assembly 100 by being attached, which is conducive to improving the stability and reliability of the connection. The extension end 230 is provided with a bending portion 231 so that the portion of the extension end 230 that is separated from the plane where the plane plate 220 is located forms the elastic portion 210, that is, the elastic portion 210 is formed by bending the extension end 230. The elastic portion 210 is also an integral structure, which is conducive to improving the strength and reliability of the elastic portion 210.

[0039] refer to Figure 2 and Figure 3 , the elastic portion 210 is formed by bending the extension end 230, and the elastic separation force provided by the elastic portion 210 can be calculated by the following formula:

[0040]

[0041] in, An elastic separation force provided to the elastic portion 210; is the elastic modulus of the elastic portion 210; is the width of the elastic portion 210; is the thickness of the elastic portion 210; is the deflection, i.e., the height of the elastic part 210 after bending, which is determined by the distance between the highest point of the elastic part 210 and the plane where the flat plate 220 is located; is the length of the elastic portion 210 , that is, the distance from the bent portion 231 of the extending end 230 to the end of the extending end 230 .

[0042] It is understandable that the leaf spring 200 is formed by a flat plate 220 and an extended end 230 of an integral structure, and the extended end 230 is bent to form the elastic portion 210 , the thickness of which is generally equal to that of the flat plate 220 .

[0043] refer to Figure 2 and Figure 3 In some embodiments of the present invention, when four elastic parts 210 are provided, the total elastic separation force provided is:

[0044]

[0045] It can be understood that on the premise of ensuring the reliable connection of the connector, an appropriate number of extension ends 230 can be set according to requirements to form a corresponding number of elastic parts 210, thereby providing sufficient elastic separation force.

[0046] Reference Figures 1 to 3 , in some embodiments of an auxiliary separation structure of a connector of the present utility model, the threaded connection structure 300 includes a first threaded member and a first threaded hole provided on the bottom plate assembly 100. The first threaded member corresponds to the first threaded hole and there are at least two first threaded holes. The flat plate 220 is provided with fixing holes 221 corresponding to the first threaded holes. The first threaded member passes through the fixing holes 221 and the first threaded member is threadedly connected to the first threaded hole.

[0047] The first threaded member passes through the fixing holes 221 of the flat plate 220, and then the first threaded member is threadedly connected to the first threaded hole on the bottom plate assembly 100 to fix the flat plate 220 on the bottom plate assembly 100, so as to fix the leaf spring 200 on the bottom plate assembly 100. There are at least two first threaded holes on the bottom plate assembly 100. The number of fixing holes 221 on the flat plate 220 and the number of first threaded members are equal to the number of first threaded holes. By threading more than two first threaded members through the fixing holes 221 and connecting them to the first threaded holes, it is possible to prevent the flat plate 220 from rotating, avoid the overall offset of the leaf spring 200 when the elastic part 210 is squeezed, which is beneficial to make the leaf spring 200 more stable. And more first threaded members are threadedly connected to the first threaded holes, which is beneficial to make the connection between the leaf spring 200 and the bottom plate assembly 100 more firm and reliable.

[0048] Reference Figure 1 , in some embodiments of an auxiliary separation structure of a connector of the present utility model, the bottom plate assembly 100 is provided with a first sinking groove part 120 corresponding to the flat plate 220 and a second sinking groove part 130 corresponding to the elastic part 210. The flat plate 220 is located in the first sinking groove part 120, and the second sinking groove part 130 is located below the elastic part 210 so that the elastic part 210 can enter the second sinking groove part 130 when being squeezed.

[0049] The bottom plate assembly 100 is provided with a first sunk groove portion 120 to accommodate the flat plate 220, so that the flat plate 220 does not protrude from the upper plane of the bottom plate assembly 100, avoiding the flat plate 220 affecting the connection of the first connector 110. The bottom plate assembly 100 is provided with a second sunk groove portion 130. When the elastic portion 210 is squeezed, the elastic portion 210 enters the second sunk groove portion 130, that is, the second sunk groove portion 130 accommodates the elastic portion 210, so that the elastic portion 210 can not protrude from the upper plane of the bottom plate assembly 100, avoiding the elastic portion 210 affecting the connection of the first connector 110. In this way, through the first sunk groove portion 120 and the second sunk groove portion 130, the thickness of the leaf spring 200 can be prevented from affecting the connection of the first connector 110, enabling the first connector 110 to be fully close to the second connector 610 to be connected, which is beneficial to improving the connection reliability of the first connector 110.

[0050] It can be understood that the flat plate 220 and the elastic portion 210 are of an integral structure, and the first sunk groove portion 120 and the second sunk groove portion 130 are communicated to form a whole sunk groove. When the elastic portion 210 is squeezed, the whole leaf spring 200 can be accommodated.

[0051] In some embodiments of a connector auxiliary separation structure of the present utility model, it further includes a pressing structure provided on the bottom plate assembly 100. The pressing structure is used to connect with the substrate assembly 600 to squeeze the elastic portion 210 so that the elastic portion 210 enters the second sunk groove portion 130.

[0052] When the first connector 110 is connected to the second connector 610, the bottom plate assembly 100 needs to be close to the substrate assembly 600. To improve the connection stability and reliability, a pressing structure is provided on the bottom plate assembly 100 to connect with the substrate assembly 600 to make the connection between the first connector 110 and the second connector 610 more stable and reliable. When the pressing structure makes the bottom plate assembly 100 and the substrate assembly 600 close and press together, the elastic portion 210 will enter the second sunk groove portion 130.

[0053] Reference Figure 1 , in some embodiments of a connector auxiliary separation structure of the present utility model, the pressing structure includes a second threaded member and a connection through hole 410 provided on the bottom plate assembly 100. The elastic portion 210 is provided with a notch 211 corresponding to the connection through hole 410. The second threaded member is used to pass through the connection through hole 410 and the notch 211 and be threadedly connected with the substrate assembly 600 to squeeze the elastic portion 210.

[0054] The bottom plate assembly 100 is provided with a connecting through hole 410 and the elastic part 210 is provided with a notch 211. After the second threaded part passes through the connecting through hole 410 and the notch 211 in sequence, the second threaded part is threadedly connected to the substrate assembly 600. The second threaded part makes the substrate assembly 600 approach the bottom plate assembly 100 to squeeze the elastic part 210, so that the elastic part 210 enters the second sinking groove part 130. When the elastic part 210 is squeezed and deformed downward, it will have a horizontal displacement. The notch 211 allows the elastic part 210 to have a horizontal displacement relative to the second threaded part, avoiding horizontal extrusion between the second threaded part and the elastic part 210. Therefore, the notch 211 makes the process of the second threaded part squeezing the elastic part 210 into the second sinking groove part 130 more reliable, and makes the error margin of the designed position of the connecting through hole 410 larger, which is beneficial to reducing the design and processing difficulty.

[0055] Reference Figure 5 , in some embodiments of the present utility model, the substrate assembly 600 is provided with a second threaded hole 620. After the second threaded part passes through the connecting through hole 410 and the notch 211, it is threadedly connected to the second threaded hole 620, so that the substrate assembly 600 approaches and presses against the bottom plate assembly 100.

[0056] In some embodiments of the present utility model, the elastic part 210 may also be provided with a pressing hole. After the second threaded part passes through the pressing hole, it is threadedly connected to the connecting through hole 410, so that the elastic part 210 enters the second sinking groove part 130.

[0057] In some embodiments of the present utility model, the pressing structure may also include an implementation manner of a clamping block and a clamping notch provided on the bottom plate assembly 100. The clamping block presses against the elastic part 210 and then approaches the clamping notch. The clamping connection between the clamping block and the clamping notch makes the elastic part 210 located in the second sinking groove part 130.

[0058] Reference Figure 1 and Figure 2 , in some embodiments of an auxiliary separation structure of a connector of the present utility model, the flat plate 220 is provided with a hollow part 222, and the hollow part 222 is located at the center of the flat plate 220.

[0059] The flat plate 220 is provided with a hollow part 222, which can reduce the overall weight of the leaf spring 200 and save the manufacturing material of the leaf spring 200. And the hollow part 222 is located at the center of the flat plate 220, which is beneficial to ensuring the overall structural strength of the leaf spring 200 and avoiding the influence of too small width of some areas of the flat plate 220 on the structural strength.

[0060] In some embodiments of the present utility model, reference Figure 1 and Figure 2, the planar plate 220 is rectangular, there are four extension ends 230 which are respectively arranged at the four corners of the rectangular planar plate, and the hollowed-out part 222 is also rectangular, so that the widths of the regions of the planar plate 220 outside the hollowed-out part 222 are approximately equal, ensuring the balance of the structural strength of the planar plate 220.

[0061] Reference Figure 1 , in some embodiments of an auxiliary separation structure of a connector of the present invention, there are two first connectors 110, the planar plate 220 is located between the two first connectors 110, there are four elastic parts 210, and two of the four elastic parts 210 are located on both sides of one first connector 110, and the other two elastic parts 210 are located on both sides of the other first connector 110.

[0062] The two first connectors 110 are located on both sides of the planar plate 220, and there are four elastic parts 210 formed by the extension ends 230 arranged at the edge of the planar plate 220, and there is one elastic part 210 on both sides of each of the two first connectors 110, so that when the first connectors 110 are connected, the elastic parts 210 on both sides of each first connector 110 provide balanced elastic separation force, facilitating the separation of the first connectors 110. Thus, by arranging the planar plate 220 between the two first connectors 110, the position of the elastic part 210 can be set by making full use of the area of the planar plate 220, and installing the planar plate 220 can provide elastic separation force for the two first connectors 110, which is beneficial to improving the installation efficiency.

[0063] Reference Figure 2 and Figure 3 , in some embodiments of an auxiliary separation structure of a connector of the present invention, the height of the highest point of the elastic part 210 from the plane where the planar plate 220 is located is 2.5 mm, the thickness of the planar plate 220 and the extension end 230 is between 1 mm and 1.5 mm, the width of the elastic part 210 is 11 mm, the length of the elastic part 210 is between 18 mm and 20 mm, and the elastic modulus of the elastic part 210 is 7×10³ kg / mm².

[0064] The entire leaf spring 200 can be made of alloy steel to provide the elasticity and durability that meet the requirements. The elastic modulus is 7×10³ kg / mm². The thickness of the leaf spring 200 needs to be moderate to avoid insufficient elastic separation force provided by being too thin and difficulty in deformation due to being too thick. The thickness of the leaf spring 200 is between 1 mm and 1.5 mm. The elastic part 210 is formed by bending the extension end 230 of the leaf spring 200. Therefore, the thickness of the elastic part 210 is also between 1 mm and 1.5 mm. Based on this, combined with the calculation formula for the total elastic separation force provided by the leaf spring 200, and further according to the situation applied to the OAM module, the appropriate deflection of the leaf spring 200 for the structure of the middle-layer connector is set, that is, the height of the highest point of the elastic part 210 from the plane where the flat plate 220 is located, and it is set to 2.5 mm. The length of the elastic part 210, that is, the length from the bending part 231 to the end edge on the extension end 230, is set to be between 18 mm and 20 mm. The width of the elastic part 210 is set to 11 mm according to the structural limitations. With these structural parameters, the elastic separation force provided by the elastic part 210 is suitable for the situation of the OAM module, making the force required for the separation of the connector within a suitable range.

[0065] The above structural parameters of the leaf spring 200 are only one embodiment of the present utility model to adapt to the situation applied to the OAM module. In other embodiments, different structural parameters can be used for design and implementation.

[0066] After designing the structural parameters of the leaf spring 200, samples can be made to verify whether the total elastic separation force provided by the leaf spring 200 meets the requirements, which is convenient for further adjusting the structural parameters or determining the application.

[0067] Next, an OAM module provided by the present utility model will be described. An OAM module described below can be mutually corresponding and referred to with a connector auxiliary separation structure described above.

[0068] Reference Figure 4 and Figure 5 Referring to

[0069] The base plate assembly 100 serves as the base plate for installing the OAM component 500 of the OAM module. In the OAM component 500, the first connector 110 is connected to the second connector 610 to achieve signal transmission of the OAM component 500, so that the OAM component 500 can transmit signals to the devices on the substrate assembly 600 through the first connector 110 and the second connector 610. During the connection process of the first connector 110 and the second connector 610, the base plate assembly 100 and the substrate assembly 600 approach each other. The elastic part 210 of the leaf spring 200 on the substrate assembly 600 contacts and presses the elastic part 210 on the base plate assembly 100, causing the elastic part 210 to deform. After the first connector 110 and the second connector 610 are successfully connected, the elastic separation force generated by the extrusion deformation of the elastic part 210 can offset a part of the bonding force between the first connector 110 and the second connector 610, reducing the separation force required when separating the first connector 110 and the second connector 610. This is beneficial to avoiding excessive separation force, making disassembly and maintenance more convenient, preventing device damage caused by excessive required separation force, and improving the reliability of the structure.

[0070] In some embodiments of the present invention, the first connector 110 and the second connector 610 are mezzanine connectors.
