However, when the claw spring structure is under stress or in the environment of high-frequency vibration and impact, the claw spring structure is prone to displacement relative to the conductive sleeve, which affects the stability of the electrical connection.

[0023] In the field of electronic components and connectors, claw spring structures, socket contact assemblies, and connectors are key structures for building electronic systems and realizing electrical connections between circuit boards or between circuit boards and external devices. Among them, the design and performance of claw spring structures have a significant impact on the overall performance, reliability, and service life of electronic systems.

[0024] The existing claw spring structure mainly relies on the frictional force generated by the interference fit between the conductive support and the conductive sleeve to assemble it in the conductive sleeve. However, when the claw spring structure is under stress or in the environment of high-frequency vibration and impact, the claw spring structure is prone to displacement relative to the conductive sleeve, which affects the stability of the electrical connection.

[0025] This invention proposes a claw spring structure to improve the assembly stability of the claw spring structure and the conductive sleeve, thereby improving the reliability of the socket contact assembly and connector.

[0026] Please see Figures 1 to 4 In one embodiment, the claw spring structure 10 includes a conductive support 110, a fixing arm 120, and a conductive elastic sleeve. The conductive support 110 has a first insertion hole, and the outer wall surface of the conductive support 110 is used to abut against the inner wall surface of the conductive sleeve 20. The fixing arm 120 is located at one end of the conductive support 110 and is arranged around the axis of the first insertion hole. The end of the fixing arm 120 away from the conductive support 110 is folded away from the axis of the first insertion hole, and the fixing arm 120 is used for mechanical interlocking with the inner wall surface of the conductive sleeve 20. The conductive elastic sleeve is located at the other end of the conductive support 110 and is arranged around the axis of the first insertion hole. The conductive elastic sleeve is configured to expand and contract radially in the first insertion hole, and the conductive elastic sleeve is used for elastic contact with the conductive pin.

[0027] The conductive support 110 is the main support part 141 of the claw spring structure 10. The conductive support 110 is a hollow cylindrical structure to form the first insertion hole. The outer peripheral surface of the wire support can be interference-fitted with and abut against the inner wall surface of the conductive sleeve 20, so as to realize the electrical connection between the claw spring structure 10 and the conductive sleeve 20, and position the claw spring structure 10, preventing the claw spring structure 10 from moving freely inside the conductive sleeve 20.

[0028] The fixed arm 120 is the main part that forms a mechanical interlock between the claw spring structure 10 and the conductive sleeve 20. The fixed arm 120 is located at one end of the conductive support 110 and is arranged along the periphery of the conductive support 110. The end of the fixed arm 120 away from the conductive support 110 is folded over, so that the fixed arm 120 can be engaged with the conductive sleeve 20 to realize the three-dimensional mechanical interlock between the claw spring structure 10 and the conductive sleeve 20. This achieves stable assembly of the claw spring structure 10 and solves the problems of micro-motion and axial movement of the claw spring structure 10 under vibration conditions.

[0029] The conductive elastic sleeve is the main part that connects the claw spring structure 10 to the conductive pin. The conductive elastic sleeve has good elastic deformation and conductivity. When the conductive pin is inserted into the conductive elastic sleeve, the sleeve expands radially in the first socket under the push of the pin, allowing the pin to enter. After the pin enters, the sleeve contracts radially in the first socket to adhere to and tighten with the pin, ensuring the stability of the electrical connection.

[0030] The technical solution of this utility model involves providing a conductive support 110, a fixing arm 120, and a conductive elastic sleeve in a claw spring structure 10. The conductive support 110 has a first insertion hole, and its outer wall surface is used to abut against the inner wall surface of the conductive sleeve 20. The fixing arm 120 is located at one end of the conductive support 110 and is arranged around the axis of the first insertion hole. The end of the fixing arm 120 away from the conductive support 110 is folded away from the axis of the first insertion hole, and the fixing arm 120 is used for mechanical interlocking with the inner wall surface of the conductive sleeve 20. The conductive elastic sleeve is located at the other end of the conductive support 110 and is arranged around the axis of the first insertion hole. The conductive elastic sleeve is configured to expand and contract radially in the first insertion hole, and is used for elastic contact with the conductive pin. Compared to the existing technology where the claw spring structure 10 is assembled to the conductive sleeve 20 by friction, the present invention provides a fixing arm 120. The fixing arm 120 is located at one end of the conductive support 110 and is folded to mechanically interlock with the conductive sleeve 20. This allows the claw spring structure 10 to remain stable relative to the conductive sleeve 20 even when under stress or in the environment of high-frequency vibration and impact, thereby improving the assembly stability of the claw spring structure 10 and the conductive sleeve 20, and thus improving the reliability of the socket contact assembly and connector.

[0031] Please see Figure 1 and Figure 2 In one embodiment, the fixing arms 120 are provided at intervals around the axis of the first insertion hole.

[0032] One end of each fixing arm 120 is fixed to the conductive support 110, and the other end of each fixing arm 120 extends and folds away from the conductive support 110. All fixing arms 120 are engaged with the inner wall of the conductive sleeve 20, which enables mechanical interlocking and multi-point fixing between the claw spring structure 10 and the conductive sleeve 20, further improving the assembly stability of the claw spring structure 10 within the conductive sleeve 20. The multiple fixing arms 120 are spaced apart around the axis of the second insertion hole, allowing for a more even distribution of the assembly force during assembly. This prevents deformation or damage to the fixing arms 120 due to excessive localized force, ensuring ease and reliability of assembly.

[0033] In one embodiment, each fixed arm 120 includes an extension 121 and a snap-fit ​​portion 122. One end of the extension 121 is connected to the conductive support 110, and the other end of the extension 121 is bent and connected to the snap-fit ​​portion 122. The snap-fit ​​portion 122 is used to snap into the inner wall surface of the conductive sleeve 20.

[0034] The snap-fit ​​portion 122 is located at the end of the extension 121 away from the conductive support 110, so as to snap-fit ​​with the conductive sleeve 20 after the conductive support 110 is inserted into the conductive sleeve 20. The inner wall of the conductive sleeve 20 is provided with a snap-fit ​​position, and the snap-fit ​​portion 122 can snap into the snap-fit ​​position to realize the mechanical interlock between the claw spring structure 10 and the conductive sleeve 20.

[0035] In one embodiment, the extension 121 is configured to be malleably deformable so that the fixing arm 120 has an assembled state and a ready-to-be-assembled state; in the ready-to-be-assembled state, the extension 121 is an arc surface protruding toward the axis of the first insertion hole, so that the snap-fit ​​portion 122 is away from the inner wall surface of the conductive sleeve 20; in the assembled state, the extension 121 is a plane, so that the snap-fit ​​portion 122 approaches and snaps into the inner wall surface of the conductive sleeve 20.

[0036] Under a preset assembly force, the extension 121 undergoes plastic deformation, causing the locking portion 122 to engage with the locking position. The preset assembly force is significantly greater than the insertion / removal force of the conductive pin, meaning that the extension 121 remains undeformed during repeated insertions and removals of the conductive pin. In the pre-assembly state, the extension 121 is an arc-shaped surface protruding towards the axis of the first insertion hole, causing the locking portion 122 to be close to the axis of the first insertion hole and away from the locking position. This facilitates easier insertion of the fixing arm 120 into the conductive sleeve 20 during assembly. At this time, the locking portion 122 is perpendicular to the axis of the first insertion hole and forms a first angle with the extension 121. In the assembled state, the extension 121 is a plane parallel to the axis of the first insertion hole, so that the snap-fit ​​part 122 is away from the axis of the first insertion hole and snaps into the snap-fit ​​position. At this time, the snap-fit ​​part 122 is perpendicular to the axis of the first insertion hole and has a second included angle with the extension 121. The second included angle is about 90 degrees and is smaller than the first included angle, which further ensures that the fixing arm 120 can enter the conductive sleeve 20 more smoothly in the unassembled state, and can be more securely snapped into the snap-fit ​​position in the assembled state.

[0037] In one embodiment, in the assembled state, one end of the plurality of snap-fit ​​portions 122 away from the axis of the first socket forms an assembled outer diameter around the first socket, the assembled outer diameter being larger than the inner diameter of the conductive sleeve 20.

[0038] In the pre-assembly state, since the snap-fit ​​portion 122 is away from the snap-fit ​​position, the end of all snap-fit ​​portions 122 of all fixed arms 120 away from the axis of the first insertion hole forms the pre-assembly outer diameter of the integral fixed arm 120 around the first insertion hole. The pre-assembly outer diameter is adapted to or slightly larger than the inner diameter of the conductive sleeve 20, so that the claw spring structure 10 can be installed into the conductive sleeve 20 as a whole. In the assembled state, since the snap-fit ​​portion 122 is snapped into the snap-fit ​​position, the end of all snap-fit ​​portions 122 of all fixed arms 120 away from the axis of the first insertion hole forms the assembled outer diameter of the integral fixed arm 120 around the first insertion hole. The assembled outer diameter is larger than the pre-assembly outer diameter and larger than the inner diameter of the conductive sleeve 20, so that the snap-fit ​​portion 122 is stably snapped into the slot 230 and forms a rigid mechanical stop with the slot 230, thereby ensuring that the snap-fit ​​portion 122 will not easily come out of the slot 230.

[0039] The assembly process of the claw spring structure 10 includes a pre-assembly stage and a core assembly stage. Pre-assembly is performed before the core assembly stage. In the pre-assembly stage, the claw spring structure 10 is assembled into a predetermined position within the conductive sleeve 20, with the locking portion 122 of the fixing arm 120 facing the locking position of the conductive sleeve 20, and the outer peripheral surface of the conductive support 110 abutting against the inner wall of the conductive sleeve 20. In the core assembly stage, a 30° conical angle enlargement is used to apply radial and axial forces to the claw spring structure 10, causing it to move axially along the first insertion hole, aligning the locking portion 122 with the middle position of the locking position to ensure accurate locking. Then, a 60° conical angle enlargement is used to apply a pre-set radial assembly force to the fixing arm 120, forcing the extension 121 to undergo plastic deformation so that the locking portion 122 is fully locked into the locking position, and maintaining this position for a pre-set time to ensure the extension 121 is properly shaped. After the 60° tapered reaming pin is removed, the extension 121 is allowed to spring back by 0.02mm to 0.03mm. Of course, in other embodiments, the assembly tool can be flexibly selected according to actual needs, and there are no restrictions here.

[0040] The technical solution of this utility model embodiment, by setting a fixed arm 120 with an extension 121 and a locking part 122, utilizes the plastic deformation characteristics of the extension 121 to achieve a stable locking connection between the fixed arm 120 and the conductive sleeve 20, simplifying the assembly process and improving assembly efficiency. Under conditions of insertion / extraction force or vibration and impact, the locking part 122 can stably engage in the locking position, forming a three-dimensional mechanical interlocking structure. This effectively prevents displacement of the claw spring structure 10 relative to the conductive sleeve 20, reduces temperature fluctuations in the claw spring structure 10, ensures stable electrical connection, and further improves the reliability of the claw spring structure 10.

[0041] Please see Figure 1 and Figure 2In one embodiment, the conductive elastic sleeve includes a plurality of conductive elastic claws 130, which are disposed on the conductive support 110 and are evenly spaced around the axis of the first insertion hole.

[0042] Specifically, each conductive elastic claw 130 has good elastic deformation capability and conductivity. All conductive elastic claws together form a clamping space around the axis of the first socket, and the clamping space is connected to the first through hole. When the conductive pin is not inserted into the clamping space, all conductive elastic claws 130 are close to the axis of the first socket. When the conductive pin is inserted into the clamping space, the conductive elastic claws 130 expand radially along the first socket under the pushing force of the conductive pin, so that the conductive pin can smoothly enter the clamping space. After the conductive pin is fully inserted into the clamping space, the conductive elastic claws 130 contract radially along the first socket under the action of their own elastic force, and the conductive elastic claws 130 tightly fit the outer surface of the conductive pin to form a stable and reliable elastic contact with the conductive pin. After the conductive pin is pulled out of the clamping space, the conductive elastic claws 130 return to their original shape under the action of their own elastic force.

[0043] In one embodiment, the ends of the plurality of conductive elastic claws 130 away from the conductive support 110 are inclined toward the axis of the first socket.

[0044] All conductive elastic claws 130 have their ends away from the conductive support 110 inclined towards the axis of the first insertion hole, causing the ends of the conductive elastic sleeves away from the conductive support 110 to be contracted. That is, the inner diameter of the clamping space at the end away from the wire support is smaller than the inner diameter of the clamping space at the end closer to the wire support. After the conductive pin is fully inserted into the clamping space, the ends of all conductive elastic claws 130 away from the conductive support 110 are in close contact with the conductive pin to stably clamp the conductive pin.

[0045] The technical solution of this utility model embodiment reduces the contact area between the conductive pin and the conductive elastic sleeve by setting the conductive elastic sleeve as multiple spaced conductive elastic claws 130, thereby reducing wear during insertion and removal while ensuring a stable electrical connection. The conductive elastic claws 130 are inclined, which allows them to provide a more uniform and stable clamping force when holding the conductive pin, effectively preventing the conductive pin from shaking or shifting during insertion and removal, and further improving the reliability and stability of the electrical connection.

[0046] Please see Figure 1 and Figure 2 In one embodiment, a flip claw 140 is provided at one end of the conductive elastic claw 130 away from the conductive support 110. The flip claw 140 is folded in a direction away from the axis of the first insertion hole and is used to abut against the inner wall surface of the conductive sleeve 20.

[0047] When the conductive sleeve 20 is fully inserted into the clamping space, the flipping claw 140 abuts against the conductive sleeve 20 to ensure that the corresponding conductive elastic claw 130 abuts against the conductive sleeve 20. Specifically, in one embodiment, one of any two adjacent conductive elastic claws 130 is provided with a flipping claw 140, that is, the conductive elastic claws 130 with flipping claws 140 are spaced apart from the conductive elastic claws 130 without flipping claws 140, so as to ensure the stability of the contact between the conductive elastic claws 130 and the conductive pin, while avoiding the displacement of the conductive pin relative to the axis of the first insertion hole after it is inserted into the clamping space. Of course, in other embodiments, any part of the conductive elastic claws 130 is provided with flipping claws 140, which is not limited here. Among them, when one of any two adjacent conductive elastic claws 130 is provided with a flipping claw 140, the overall structure of the conductive elastic sleeve is more stable and can provide a more uniform support force for the conductive pin. The provision of flipping claws 140 in one of any two adjacent conductive elastic claws 130 is a preferred embodiment.

[0048] Furthermore, the flipping claw 140 includes a support portion 141 and an abutment portion 142. One end of the support portion 141 is bent and connected to the abutment portion 142, and the other end of the support portion 141 is bent and connected to the conductive elastic claw 130. The abutment portion 142 is used to abut against the inner wall of the wire sleeve. The abutment portion 142 is arranged parallel to the axis of the first insertion hole, and the support portion 141 is inclined relative to the axis of the first insertion hole. The end of the support portion 141 that connects to the abutment portion 142 is closer to the conductive support body 110 than the end of the support portion 141 that connects to the conductive elastic claw 130, so that the abutment portion 142 is located between the conductive elastic claw 130 and the inner wall surface of the conductive sleeve 20, to ensure that after the conductive pin is fully inserted into the clamping space, the flipping claw 140 provides stable support for the conductive elastic claw 130.

[0049] The technical solution of this utility model embodiment, by providing flip-claws 140 on some of the conductive elastic claws 130, can increase the contact pressure between the conductive elastic claws 130 and the conductive pin, ensuring the contact stability between the conductive elastic claws 130 and the conductive pin; at the same time, it reduces the fatigue loosening of the conductive elastic claws 130 during the long-term insertion and removal of the conductive pin, ensuring that the conductive elastic claws 130 can stably clamp the conductive pin during the frequent insertion and removal of the conductive pin, and improving the service life of the claw spring structure 10.

[0050] In one embodiment, the conductive support 110, the fixing arm 120, the conductive elastic claw 130, and the flipping claw 140 are integrally formed to ensure the overall structural stability of the claw spring structure 10. Specifically, the claw spring structure 10 is configured as a metal material with good elasticity and conductivity, such as beryllium bronze, phosphor bronze, chromium zirconium copper, or stainless steel, to ensure that the claw spring structure 10 maintains stable elastic deformation and is not prone to plastic deformation during long-term use, thereby ensuring a stable connection between the claw spring structure 10, the conductive sleeve 20, and the conductive pin; at the same time, it also ensures that the claw spring structure 10 maintains good conductivity to reduce resistance during electrical connection, thereby reducing energy loss and heat generation. Among them, beryllium bronze not only has high elasticity and conductivity, but also high strength and hardness, which can withstand certain external forces without damage, enhancing the durability and reliability of the claw spring structure 10.

[0051] Please see Figure 3 and Figure 4 This utility model also proposes a socket contact assembly, including a conductive sleeve 20 and a claw spring structure 10 from the above embodiments. The specific structure of the socket contact is as described in the above embodiments. Since the socket contact assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The conductive sleeve 20 is provided with a connected second socket and a slot 230. The slot 230 is located on the wall of the second socket. The claw spring structure 10 is installed in the second socket, and the fixing arm 120 of the claw spring structure 10 can be engaged in the slot 230.

[0052] Specifically, the wall of the second socket is recessed away from the axis of the second socket to form a groove 230. The groove 230 is arranged in a circle around the axis of the second socket, and the groove 230 is the engagement position to engage with the engagement part 122 of the claw spring structure 10. The claw spring structure 10 is placed entirely inside the second socket. The first socket and the second socket are coaxially arranged and connected. The conductive support 110 abuts against the wall of the second socket. The engagement part 122 of the fixing arm 120 is engaged in the groove 230. The abutting part 142 of the flip claw 140 is located between the wall of the second socket and the conductive elastic claw 130. In one embodiment, the conductive sleeve 20 is made of copper, which gives the conductive sleeve 20 good conductivity, effectively reducing the loss generated during current transmission; and also gives the conductive sleeve 20 good corrosion resistance and high temperature resistance, thereby improving the service life of the socket contact assembly. Of course, in other embodiments, the conductive sleeve 20 can also be made of high-temperature resistant and conductive materials such as aluminum or gold, and no limitation is made here.

[0053] In one embodiment, the second insertion hole includes a first sub-hole 210 and a second sub-hole 220 that are connected to each other. The slot 230 is located at the junction of the first sub-hole 210 and the second sub-hole 220. The outer wall surface of the conductive support 110 of the claw spring structure 10 abuts against the hole wall of the second sub-hole 220. The diameter of the first sub-hole 210 is larger than the diameter of the second sub-hole 220.

[0054] The recessed area where the first sub-hole 210 and the second sub-hole 220 meet forms a groove 230, resulting in a difference in height between the two opposing groove walls of the groove 230. This allows the engaging portion 122 to pass through the first sub-hole 210 and align with the groove 230 during the pre-assembly stage. Specifically, in the pre-assembly state, all engaging portions 122 of all fixing arms 120 form a pre-assembly outer diameter, which is larger than the outer diameter of the conductive support 110. The diameter of the first sub-hole 210 is adapted to or slightly larger than the pre-assembly outer diameter, so that the claw spring structure 10 can pass through the first sub-hole 210 and enter the second insertion hole, avoiding obstruction of the fixing arm 120 in the pre-assembly state by the first sub-hole 210. In the assembled state, all engaging portions 122 of all fixing arms 120 form an assembled outer diameter, which is larger than the pre-assembly outer diameter and larger than the inner diameter of the first sub-hole 210, ensuring that the engaging portion 122 is stably engaged in the groove 230 without easily dislodging from it. The diameter of the second sub-hole 220 is adapted to the outer diameter of the conductive support 110, so that when the claw spring structure 10 is assembled with the conductive sleeve 20, the outer wall of the conductive support 110 abuts against the hole wall of the second sub-hole 220, thereby achieving positioning and support, and ensuring a stable electrical connection between the claw spring structure 10 and the conductive sleeve 20.

[0055] In one embodiment, the diameter of the first sub-hole 210 is gradually increased in the direction away from the second sub-hole 220, such that the hole wall of the first sub-hole 210 has a guiding slope 211, which is used to guide the conductive pin into the first sub-hole 210 and the second sub-hole 220.

[0056] Specifically, in one embodiment, the first sub-hole 210 includes a columnar portion and a tapered portion. One end of the columnar portion is connected to the slot 230, and the other end of the columnar portion is connected to the tapered portion. The diameter of the tapered portion gradually increases in the direction away from the second sub-hole 220 to form a guide slope 211. In another embodiment, the overall diameter of the first sub-hole 210 gradually increases in the direction away from the second sub-hole 220 to form a guide slope 211.

[0057] In the technical solution of this utility model embodiment, by dividing the second socket into a first sub-hole 210 and a second sub-hole 220, and making the diameter of the first sub-hole 210 larger than that of the second sub-hole 220, the second sub-hole 220 mainly provides space for the installation of the claw spring structure 10 and achieves electrical connection with the claw spring structure 10. The first sub-hole 210 mainly provides clearance for the installation of the claw spring structure 10 and provides guidance for the insertion of the conductive pin. In particular, the setting of the guide slope 211 enables the conductive pin to be guided more smoothly during the insertion process, reducing the resistance during insertion and improving the ease of use of the socket contact assembly.

[0058] This utility model also proposes a connector, including the socket contact element of the above embodiments. The specific structure of the socket contact element is as described in the above embodiments. Since this connector adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0059] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
