[0029] In order to solve the technical problem that the plug-in life of the existing electrical connector spring 10 structure is short, the technical solution proposes a spring 10 for an electrical connector, the electrical connector having a female socket 20 and a plug-in slot provided on the female socket 20, the spring 10 includes:
[0030] The cylinder 100 is used to be arranged in the plug-in slot. The cylinder 100 has a first end and a second end opposite to each other. The first end and the second end are connected by a plurality of bars 110. The first end is used to be fixed to the female seat 20, and the second end is used to be slidably connected to the plug-in slot.
[0031] The elastic structure 200 is disposed at the second end of the cylinder 100 . The elastic structure 200 is used to elastically abut against the bottom of the insertion slot to eliminate the axial stress of the cylinder 100 when plugging or unplugging.
[0032] Furthermore, the elastic structure 200 and the cylinder 100 are integrally formed.
[0033] Compared with the prior art, in the technical solution of the utility model, the reed 10 is arranged in the female seat 20 of the electrical connector, the female seat 20 has a plug-in slot, the reed 10 has a cylinder 100 structure, the cylinder 100 has a first end and a second end opposite to each other, the first end and the second end are connected by a plurality of bars 110, when the male plug is inserted into the female seat 20, the outer peripheral wall of the male plug is in elastic contact with the bars 110 to realize electrical connection, in addition, the first end is fixedly connected to the female seat 20, and the second end is slidably connected to the plug-in slot, in addition, the reed 10 It also includes an elastic structure 200, which is arranged at the second end of the cylinder 100. The elastic structure 200 is in elastic contact with the slot body of the plug-in slot. When the male plug is inserted, the bars 110 of the cylinder 100 expand and stretch outward. At this time, the overall length of the cylinder 100 increases, and the second end can slide along the axial direction of the reed 10 to reduce the stress in the cylinder 100. The elastic structure 200 will be compressed and elastically deformed to eliminate the axial stress caused by the length change, thereby reducing the damage to the reed 10 caused by the stress and extending the service life of the reed 10.
[0034] Specifically, Figure 1 and Figure 2In the present embodiment, the spring sheet 10 is used as a component of an electrical connector, which has a female socket 20 and a plug-in slot arranged on the female socket 20. The spring sheet 10 includes a cylinder 100, which is an integrally formed cylindrical structure. The cylinder 100 has a first end and a second end opposite to each other along its own axial direction. Between the first end and the second end, a plurality of bars 110 are arranged. The bars 110 extend along the length direction of the cylinder 100, and the bars 110 surround the cylinder 100 along the circumferential direction of the cylinder 100 to form a cylinder wall structure. The two ends of the bars 110 are respectively connected to the first end and the second end, and the middle position of the bars 110 is bent toward the center of the cylinder 100 to form a waisted structure. In this way, when connecting, the male head can be inserted into the high cylinder 100 from the first end and abut against the middle position of the bars 110. At this time, the bars 110 are deformed in a direction away from the center of the cylinder 100 and elastically abut against the male head to achieve electrical connection. In order to reduce the internal stress of the spring leaf 10 during the above-mentioned connection process, in the present embodiment, the first end of the cylinder 100 is fixedly connected to the female seat 20, and the second end of the cylinder 100 is slidably connected to the female seat 20, and the second end can slide along the axial direction of the cylinder 100. In addition, an elastic structure 200 is also provided at the second end. The elastic structure 200 can be a structure similar to an axial compression spring or a butterfly spring. The elastic structure 200 can be separately provided from the cylinder 100 and abut against the bottom of the slot of the plug-in slot. In this way, when connected, the grid bar 110 is deformed, and the length of the cylinder 100 tends to increase. The second end can slide away from the first end and compress the elastic structure. The elastic structure 200 is formed, and the internal stress of the cylinder 100 caused by the change in length will be absorbed by the compression deformation of the elastic structure 200, thereby reducing the stress level in the cylinder 100, which is beneficial to increasing the number of plug-in and unplug usage and the service life of the reed 10. In addition, the elastic structure 200 can be made of conductive material, so that the current can also flow between the reed 10 and the female seat 20 through the elastic structure 200, which is beneficial to reducing the resistance of the electrical connector and reducing current loss. In addition, since the elastic structure 200 is elastically connected to the plug slot and the cylinder 100, the reliability of the electrical connection between the reed 10 and the female seat 20 can also be improved. In addition, in order to facilitate processing, the elastic structure 200 can be manufactured in an integrated manner with the cylinder 100, which can simplify the manufacturing process and reduce processing costs.
[0035] Furthermore, the elastic structure 200 includes a deformation body 210, two opposite ends of the deformation body 210 are connected to the second end, and the middle portion of the deformation body 210 is bent away from the cylinder 100 and extends to surround the second end of the cylinder 100 to form a deformation hole 220. Specifically, as Figure 2In this embodiment, the elastic structure 200 includes a deformable body 210, which is a strip-shaped structure. The two opposite ends of the deformable body 210 are spaced apart and connected to the end surface of the second end. The middle part of the deformable body 210 is away from the second end and bends and extends along the axis direction of the cylinder 100. In this way, a deformation hole 220 can be formed between the deformable body 210 and the second end of the cylinder 100. After assembly, the middle part of the deformable body 210 can abut against the bottom of the slot of the plug-in slot. When the second end slides, the middle part of the deformable body 210 can be bent and deformed to make the deformation hole 220 smaller, thereby absorbing the stress in the cylinder 100. Compared with the structure similar to the axial compression spring or butterfly spring in the above-mentioned embodiment, the elastic structure 200 in this scheme has the advantages of simple structure and easy processing, which is conducive to reducing production costs.
[0036] Furthermore, a plurality of deformation bodies 210 are arranged at intervals along the circumference of the cylinder 100. In addition, in order to ensure that the cylinder 100 is subjected to uniform force, a plurality of deformation bodies 210 can be arranged at equal intervals along the circumference of the cylinder 100, so that the force between the cylinder 100 and the female seat 20 can be dispersed, thereby avoiding local stress concentration of the cylinder 100 and the elastic structure 200, which is conducive to further extending the service life of the spring 10.
[0037] Furthermore, the second end is also provided with a deformation groove 120, and a deformation groove 120 is provided between every two adjacent deformation bodies 210. In addition, in order to improve the absorption effect of the internal stress of the cylinder 100, the second end can also be provided with a deformation groove 120, and a deformation groove 120 can be provided between every two adjacent deformation bodies 210, and the deformation groove 120 can extend along the axial direction of the cylinder 100, so that it is equivalent to thinning the connection position between the two ends of the deformation body 210 and the cylinder 100, so that the position is more prone to deformation, so that the deformation body 210 can be deformed under a smaller force, thereby further improving the absorption effect of the internal stress of the cylinder 100.
[0038] Furthermore, a plurality of grid bars 110 are arranged in a spiral shape. Figure 2 The bars 110 are arranged in a spiral shape, which can improve the ability of the reed 10 to bear loads in the radial direction, and is beneficial to improving the overall structural strength of the reed 10 .
[0039] The utility model also provides an electrical connector, comprising:
[0040] The female seat 20 is provided with a plug-in slot with an opening on one side;
[0041] The reed 10 is disposed in the plug-in slot, a first end of the reed 10 is connected to a position close to an opening in the plug-in slot, and a second end thereof is elastically abutted against a slot bottom of the plug-in slot through an elastic structure 200 .
[0042] The specific structure of the spring 10 refers to the above embodiments. Since the electrical connector adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
[0043] Furthermore, the first end of the spring 10 is welded or riveted to the female base 20. In order to improve the reliability of the electrical connection, the first end of the spring 10 can be connected to the female base 20 by welding or riveting, so that the connection strength between the spring 10 and the female base 20 can be improved, thereby ensuring the reliability of the electrical connection.
[0044] Furthermore, a chamfered structure is provided at the periphery of the opening. In order to facilitate the plugging and unplugging of the electrical connector, a chamfered structure can also be provided at the opening of the female socket 20, and when the male plug is plugged in, the male plug can be smoothly plugged in with the spring 10 under the guidance of the chamfered structure, which is conducive to improving the convenience of plugging the electrical connector.
[0045] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
