Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a connector spring and mounting frame. Background Technology

[0002] The connector mounting frame is used to house the connector module. The connector module and the mounting frame are inserted together into the connector housing. The connector module is connected to the housing through the mounting frame. In this way, the connector modules can be modularly combined and arranged in the connector through the mounting frame.

[0003] Mounting frames typically consist of a frame body and spring contacts. The spring contacts are embedded within the frame body. In existing technologies, the movable side of the spring contact has a protruding tongue that passes through a slot in the frame body. When the connector module is inserted into the mounting frame, the protruding tongue secures the connector module's mounting bracket. However, due to the small contact area between the protruding tongue and the connector module's mounting bracket, there is a risk that the mounting bracket may be pierced by the protruding tongue during use, leading to a failure in the connection between the connector module and the mounting frame. Furthermore, due to the small contact area, the local pressure at the contact point is relatively high, which can easily cause local wear or deformation of the connector module when subjected to strong vibrations or impacts, thereby affecting the connector's insertion and extraction performance or stability. Utility Model Content

[0004] Therefore, it is necessary to provide a connector spring and mounting frame that can reliably connect connector modules.

[0005] A connector spring and a mounting frame are disclosed for accommodating a connector module.

[0006] The frame body has a slot on the side wall corresponding to the insertion direction of the connector module;

[0007] At least one spring clip assembly, each spring clip assembly including two spring clips, one end of each spring clip having a fixing hole, the two spring clips being respectively disposed on opposite outer side walls of the frame body, the fixing hole communicating with the slot, when the connector module is inserted into the frame body, the mounting plate is engaged in the slot and at least partially extends into the fixing hole, the bottom surface of the slot restricts the movement of the connector module in the insertion direction, and the top surface of the fixing hole restricts the movement of the connector module in the opposite direction of the insertion direction, so as to achieve the fixation of the connector module relative to the frame body;

[0008] The spring includes a fixed section, a transition section, and a movable section. The movable section does not coincide with the projection of the slot in the insertion direction of the connector module.

[0009] Optionally, the frame body includes an assembly groove, the spring is disposed in the assembly groove, the assembly groove includes a bottom region, a middle region and a top region, the middle region protrudes from the top region in the insertion direction of the connector module, and the slot is located in the top region.

[0010] Optionally, the fixed section is fixedly connected to the frame body, the transition section is disposed between the fixed section and the movable section, and the movable section has the fixed hole;

[0011] The active segment protrudes relative to the transition segment. The active segment includes a first bending segment and a second bending segment. The first bending segment connects to the transition segment. The first bending segment is inclined toward the side wall of the main frame body, and the second bending segment is inclined away from the side wall of the main frame body.

[0012] Optionally, a straight section is also connected between the first bent section and the second bent section.

[0013] Optionally, the top surface of the fixing hole and the projection of the mounting plate in the insertion direction have an overlapping section.

[0014] Optionally, the spring includes a first latching part disposed in the fixed section, and the frame body further includes a second latching part disposed in the assembly groove. The first latching part and the second latching part cooperate to fix the spring in the assembly groove.

[0015] Optionally, the spring sheet further includes a limiting part, which is disposed at the end of the fixed section away from the movable section. The side wall of the frame body is provided with at least one limiting groove for each spring sheet. The limiting groove is located at the bottom end of the assembly groove, and the limiting part is configured to be disposed in the limiting groove.

[0016] Optionally, there are two limiting parts, which are respectively disposed at both ends of the fixed section. Both ends of the assembly groove are provided with limiting grooves, and the limiting parts are disposed in the limiting grooves one by one.

[0017] Optionally, there are multiple spring clip assemblies, which are spaced apart along the length of the frame body, and each spring clip assembly is used to fix one of the connector modules.

[0036] refer to Figures 1-6 This application provides a connector spring and a mounting frame. The mounting frame of the connector is used to accommodate a connector module 3. The connector module 3 includes a module body 31 and at least two protruding mounting platforms 32. The at least two mounting platforms 32 are respectively disposed on opposite side walls of the module body 31. The mounting frame includes a frame body 1 and at least one spring assembly. The side wall of the frame body 1 has a slot 11 on the side corresponding to the insertion direction of the connector module 3. Each spring assembly includes two springs 2. The two springs 2 are respectively disposed on opposite side walls of the frame body 1. One end of the spring 2 has a fixing hole 21. The fixing hole 21 communicates with the slot 11. When the connector module 3 is inserted into the frame body 1, the mounting platform 32 is engaged in the slot 11 and at least partially extends into the fixing hole 21. The bottom surface of the slot 11 restricts the movement of the connector module 3 in the insertion direction, and the top surface of the fixing hole 21 restricts the movement of the connector module 3 in the opposite direction of the insertion direction, so as to fix the connector module 3 relative to the frame body 1.

[0037] This application provides a connector spring and a mounting frame. A fixing hole 21 is provided in the spring 2, and a slot 11 is provided on the side wall of the frame body 1 corresponding to each spring 2. When the connector module 3 is embedded in the frame body 1, the mounting bracket 32 ​​is positioned in the slot 11 and extends into the fixing hole 21. The bottom surface of the slot 11 restricts the movement of the connector module 3 in the insertion direction, and the top surface of the fixing hole 21 restricts the movement of the connector module 3 in the opposite direction of insertion, thereby fixing the connector module 3. This application clamps and fixes the connector module 3 in the frame body 1 through the cooperation of the slot 11 and the fixing hole 21. Compared with the prior art, this increases the contact area and strengthens the fixing force, enabling reliable docking of the connector module 3. This application also enables quick installation and reliable disassembly of the connector module 3.

[0038] In this embodiment, the bottom surface of the slot 11 abuts against the bottom surface of the mounting platform 32, and the top surface of the fixing hole 21 abuts against the top surface of the mounting platform 32.

[0039] refer to Figure 7 The spring piece 2 is bent to form a fixed section 22, a transition section 23 and a movable section 24. The fixed section 22 is fixedly connected to the frame body 1. The transition section 23 is set between the fixed section 22 and the movable section 24. The movable section 24 has a fixing hole 21.

[0040] refer to Figure 8 The spring piece 2 is a one-piece molded metal structure. The fixed section 22 protrudes relative to the transition section 23, and the movable section 24 protrudes relative to the transition section 23. The movable section 24 includes a first bending section 241 and a second bending section 242. The first bending section 241 is connected to the transition section 23. The first bending section 241 is inclined towards the side wall of the frame body 1, and the second bending section 242 is inclined away from the side wall of the frame body 1, so that the movable section 24 has good elastic deformation performance.

[0041] Furthermore, a straight section 243 is connected between the first bending section 241 and the second bending section 242, and the straight section 243 is parallel to the transition section 23.

[0042] The top surface of the fixing hole 21 and the projection of the mounting platform 32 in the insertion direction have an overlapping section, so that the top surface of the fixing hole 21 can restrict the movement of the mounting platform 32 in the opposite direction of the insertion direction.

[0043] In this embodiment, the bottom surface of the fixing hole 21 is located in the first bending section 241. The bottom surface of the fixing hole 21 and the projection of the mounting platform 32 in the insertion direction do not overlap. At this time, the bottom surface of the fixing hole 21 can be higher than the bottom surface of the slot 11.

[0044] In other embodiments, the bottom surface of the fixing hole 21 overlaps with the projection of the mounting platform 32 in the insertion direction, the fixing hole 21 is located in the straight section 243, and the bottom surface of the fixing hole 21 is flush with or lower than the bottom surface of the slot 11. Alternatively, the top surface of the fixing hole 21 is located in the second bending section 242 and the bottom surface of the fixing hole 21 is located in the first bending section 241. In this case, the bottom surface of the fixing hole 21 is lower than the bottom surface of the slot 11.

[0045] refer to Figure 2 and Figure 6 The side wall of the frame body 1 is provided with an assembly groove 12 for each spring piece 2. The assembly groove 12 is connected to the slot 11. The spring piece 2 is set in the assembly groove 12. When the spring piece 2 is closed and locked, the spring piece 2 can be completely contained in the assembly groove 12 without protruding from the surface of the frame body 1, so as to prevent the spring piece 2 from being hooked by external objects and deformed.

[0046] Specifically, a groove 15 is provided in the area of ​​the bottom of the assembly groove 12 near the slot 11, so that a gap is formed between the groove 15 and the area of ​​the transition section 23 near the slot 11, so that the first bending section 241 has space for elastic deformation.

[0047] Specifically, the projections of the slot 11 and the movable section 24 of the spring piece 2 in the insertion direction of the connector module 3 do not overlap. That is, the projections of the top and bottom stress points of the mounting platform 32 in the insertion direction of the connector module 3 do not overlap. When in a strong vibration environment, this non-overlapping stress structure can better disperse stress, improve vibration resistance, and reduce wear caused by excessive local pressure.

[0048] Specifically, the assembly slot 12 includes a bottom area 121, a middle area 122 and a top area 123. The middle area 122 protrudes outward. The fixed section 22 is fixedly disposed in the bottom area 121. The transition section 23 fits into the middle area 122. The movable section 24 fits into the top area 123. The slot 11 is located in the top area 123.

[0049] In this embodiment, the spring piece 2 includes a first latching part 25, which is disposed in the fixing section 22. The frame body 1 also includes a second latching part 13, which protrudes into the assembly groove 12. The first latching part 25 and the second latching part 13 cooperate to fix the spring piece 2 in the assembly groove 12.

[0050] Specifically, the fixed section 22 has a through hole 26, and the first latching part 25 is located at the through hole 26. One end of the first latching part 25 is connected to the top of the through hole 26, so that the first latching part 25 has space for elastic deformation, so that the first latching part 25 can be smoothly latched into the second latching part 13.

[0051] In other embodiments, there are various ways to connect the fixed section 22 and the frame body 1, such as by fusion welding, welding, riveting, locking or screwing.

[0052] refer to Figure 2 and Figure 7 The spring piece 2 also includes a limiting part 27, which is disposed at the end of the fixed section 22 away from the movable section 24. The side wall of the frame body 1 is provided with at least one limiting groove 14 for each spring piece 2. The limiting groove 14 is located at the bottom end of the bottom area 121 of the assembly groove 12, and the limiting part 27 is configured to be disposed in the limiting groove 14.

[0053] In this embodiment, there are two limiting parts 27. The two limiting parts 27 are respectively disposed at both ends of the fixed section 22. Both ends of the bottom area 121 of the assembly groove 12 are provided with limiting grooves 14. The limiting parts 27 are disposed in the limiting grooves 14 one by one. By providing two limiting parts 27, the pressure on the spring piece 2 can be more uniform, which is beneficial to maintaining the stability of the spring piece 2 and avoiding lateral deformation of the spring piece 2 caused by unilateral force.

[0054] In other embodiments, the limiting part 27 can also be located at the other end of the fixed section 22, the transition section 23, or the movable section 24. Correspondingly, the limiting groove 14 can also be located at the other end of the bottom region 121, the middle region 122, and the top region 123, as long as the limiting part 27 does not affect the insertion of the connector module 3 into the frame body 1.

[0055] refer to Figure 3 There are multiple spring clip assemblies, which are spaced apart along the length of the frame body 1. Each spring clip assembly is used to fix a connector module 3.

[0056] Specifically, multiple spring components are evenly spaced.

[0057] In this embodiment, there are 6 sets of spring clip assemblies, 12 spring clips 2, corresponding to 12 assembly slots 12 and 12 card slots 11, which can accommodate up to 6 connector modules 3.

[0058] refer to Figure 2 The slot 11 extends through the top surface of the frame body 1, thus making way for the insertion and removal of the mounting plate 32. The two slots 11 arranged opposite each other are of different sizes.

[0059] To facilitate orientation differentiation during assembly, connector module 3 is provided with mounting posts 32 at both ends. The mounting posts 32 at both ends of connector module 3 are of different sizes. (Refer to...) Figure 3 and Figure 4 This is a structural schematic diagram of the smaller mounting bracket 32, for reference. Figure 9 and Figure 10 The diagram shows the structure of the larger mounting plate 32. The two opposite slots 11 on the frame body 1 are also different in size. Only when the two mounting plates 32 are inserted into the correct slots 11 can the connector module 3 be assembled into the inner cavity of the frame body 1, thus achieving the effect of preventing mistake-proofing.

[0060] In this embodiment, the two mounting platforms 32 have different lengths, and the two opposite slots 11 have different lengths.

[0061] In this embodiment, the fixing hole 21 matches the mounting bracket 32. Furthermore, the length of the fixing hole 21 is greater than or equal to the length of the larger mounting bracket 32, so that both mounting brackets 32 can smoothly enter the fixing hole 21.

[0062] Specifically, the mounting platform 32 is provided with a guide angle 33. The connector module 3 pushes against the movable section 24 through the guide angle 33, causing the top of the movable section 24 to elastically deform away from the frame body 1. When the connector module 3 is installed in place, the spring piece 2 returns to its original position, the bottom surface of the mounting platform 32 abuts against the slot 11, and the top surface of the fixing hole 21 is locked onto the top surface of the mounting platform 32 to prevent the connector module 3 from detaching from the frame body 1. Preferably, the top surface of the fixing hole 21 is a horizontal plane, and the bottom surface of the slot 11 is a horizontal plane.

[0063] refer to Figure 1 The frame body 1 has four side walls, which enclose an inner cavity, which is divided into multiple installation spaces for installing connector modules 3.

[0064] In this embodiment, the inner cavity is rectangular and is divided into 6 mounting spaces for mounting the connector module 3.

[0065] The assembly process of connector module 3 and mounting frame is as follows: Align connector module 3 with the mounting space of connector module 3 in frame body 1. Specifically, align the two mounting posts 32 of connector module 3 with the corresponding slots 11, with the larger mounting post 32 aligned with the larger slot 11 and the smaller mounting post 32 aligned with the smaller slot 11. Then press connector module 3 into frame body 1. The mounting posts 32 of connector module 3 push open the movable section 24 of spring piece 2 through guide angle 33 and continue to press into frame body 1. When a "click" sound is heard, connector module 3 is installed in place, and spring piece 2 automatically returns to the closed and locked state (the top surface of the fixing hole 21 of the movable section 24 of each set of spring piece 2 fastens the mounting posts 32 at both ends of connector module 3), thus completing the installation.

[0066] The disassembly process of connector module 3 and mounting frame is as follows: simultaneously flip the spring pieces 2 on both sides of connector module 3 to the outside of frame body 1, so that the spring pieces 2 are in the open state under force. At this time, the top surface of the fixing hole 21 of spring piece 2 separates from connector module 3. Continue to push connector module 3 upward until connector module 3 separates from frame body 1, and disassembly is completed.

[0067] Therefore, the mounting frame of this application allows for quick installation and removal of the connector module 3, is suitable for environments with strong vibration, and is simple and reliable to maintain.

[0068] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
