Description

Technical Field

[0001] The invention belongs to the field of electrical connectors, and in particular relates to a shielding grounding spring, a connector and a connector assembly. Background Art

[0002] The shielding grounding spring is used to shield and form a common ground between the connector and the housing of the adapter connector. The shielding grounding spring is formed by a progressive die from a metal sheet. Figure 1 When assembling, cut the shield grounding spring to the required length and then refer to the attached Figure 2 and attached Figure 3 The operator manually bends the shielding grounding spring 3 according to the shape of the connector housing (such as the socket housing 1) and installs the shielding grounding spring 3 into the connector housing with the end to end of the shielding grounding spring 3 connected to each other. After installing into the connector housing, the shielding grounding spring 3 is fixed to the connector housing by soldering.

[0003] The shielding grounding spring 3 includes a base 31, a spring piece 33 located on one side of the base 31 in the width direction, and a clamping foot 32 located on the other side of the base 31 in the width direction. One end of the spring piece 33 away from the base 31 is a contact portion for sliding and pressing with the adapter connector housing. The contact portion is cantilevered on one side in the thickness direction of the base, and each spring piece 33 is arranged at intervals along the length direction of the base 31. After the shielding grounding spring 3 is bent, the spring piece 33 is located on the inner side of the base 31, and the spring pieces 33 at the bent portion of the shielding grounding spring 3 are prone to overlap and overlap.

[0004] Spring leaf overlap refers to the phenomenon that adjacent spring leaves, especially the contact parts, interfere with each other during the bending process of the shielding grounding spring, so that the shielding grounding spring cannot be effectively bent into place. This will result in the base part of the bent part of the shielding grounding spring being unable to fit tightly against the connector housing during assembly, and the shielding grounding spring cannot be firmly welded to the connector housing, increasing the risk of the shielding grounding spring falling off during use.

[0005] Reed overlap means that after the shielding grounding spring is forcibly bent, the reed at the bent part is deformed under a large force, so that part or all of the contact part of the reed is lifted up and cannot contact the housing of the adapter connector. On the one hand, it will cause the contact area between the shielding grounding spring and the housing of the adapter connector to be smaller, making it difficult to meet the shielding requirements; on the other hand, the force on the reed at the bent part is also uneven, and there is a greater risk of breakage during use.

[0006] Increasing the interval between the spring leaves of the shielding grounding spring can prevent the spring leaves at the bent portion from overlapping and lapped, but increasing the interval between the spring leaves will lead to a poor shielding effect, making it difficult to meet usage requirements. Summary of the invention

[0038] The present invention is further described in detail below in conjunction with embodiments.

[0039] In order to solve the problems in the prior art, the basic concept of the present invention is to change the shape of the spring leaf so that the ends of the spring leaf are staggered along the width direction of the base portion, so that during the bending process of the shielding grounding spring, the parts of adjacent spring leaves away from the base portion will not interfere with each other, thereby enhancing the bending ability of the shielding grounding spring.

[0040] Specific embodiment 1 of the connector assembly provided by the present invention: A connector assembly, see attached Figure 4 and attached Figure 5 , including a male connector and a female connector. In this embodiment, the male connector is a plug and the female connector is a socket. Both the plug and the socket have a metal conductive shell. During the plug-to-socket process, the end of the plug shell 2 needs to be inserted into the end of the socket shell 1.

[0041] A shielding grounding spring 3 is provided in the plug shell 2, which is used to connect the shells of the plug and the socket to the same ground after the plug and the socket are plugged in, and plays a shielding role between the shells of the plug and the socket. In this embodiment, the socket is a connector for installing the shielding grounding spring 3, and the plug is an adapter connector of the socket.

[0042] See attached Figure 6 and attached Figure 7 The shielding grounding spring 3 includes a base 31, a spring piece 33 connected to the same side of the base 31 in the width direction, and a clamping foot 32 connected to the other side of the base 31 in the width direction. The spring piece 33 and the clamping foot 32 are evenly spaced along the length direction of the base 31. Figure 5 The inner side of the socket connector is provided with an annular inner convex edge 11, and the clamping foot 32 is bent into a U shape. During the assembly process, the clamping foot 32 is clamped on the outer side of the inner convex edge 11, so that the inner convex edge 11 is used to limit the clamping foot 32 in the plugging and unplugging direction of the plug and the socket. The specific structure of the clamping foot 32 is the same as that of the prior art, and will not be repeated here.

[0043] In order to install the shielding grounding spring 3 into the socket, the operator needs to bend the shielding grounding spring 3. Specifically, the final bending shape of the shielding grounding spring 3 can be determined according to the shape of the plug hole on the socket housing 1. Figure 8 The waist shape and attachment Fig. 9 In other embodiments, the shielding grounding spring 3 can also be bent into a rounded rectangle, and the spring leaf 33 is located on the inner side of the base portion 31 after bending.

[0044] See attached Figure 6 and attached Figure 7 , and combined with the attached Fig.10The spring piece 33 includes a long spring piece 331 and a short spring piece 332, and the long spring piece 331 and the short spring piece 332 are alternately arranged along the length direction of the base part 31. The two ends of the long spring piece 331 and the short spring piece 332 are respectively a bending portion and a contact portion, wherein the bending portion is an end portion of the long spring piece 331 and the short spring piece 332 connected to the base part 31, and the bending portion is formed by arc bending processing, and the contact portion is an end portion of the long spring piece 331 and the short spring piece 332 away from the base and used for sliding and pressing with the plug housing 2, and the bending portion enables each contact portion to be cantilevered on the same side in the thickness direction of the base part 31. The bending portion of the long spring piece 331 is the first bending portion 3311, and the bending portion of the short spring piece 332 is the second bending portion 3321; the contact portion of the long spring piece 331 is the first contact portion 3312, and the contact portion of the short spring piece 332 is the second contact portion 3322. The first bending portion 3311 and the second bending portion 3321 are aligned in the length direction of the substrate to facilitate bending processing.

[0045] The long spring piece 331 also includes an extension portion 3313 and an adjustment portion 3314 located between the first bending portion 3311 and the first contact portion 3312, one end of the extension portion 3313 is connected to the first bending portion 3311, the other end of the extension portion 3313 is connected to the adjustment portion 3314, and one end of the adjustment portion 3314 away from the extension portion 3313 is connected to the first contact portion 3312. The extension portion 3313 and the first bending portion 3311 have a smooth transition, and the junction between the extension portion 3313 and the adjustment portion 3314 is an angle structure, so that an angle greater than 0° and less than 180° is formed between the extension portion 3313 and the adjustment portion 3314. The second contact portion 3322 corresponds to the angle between the extension portion 3313 and the adjustment portion 3314 in the width direction of the base portion 31. At the angle between the extension portion 3313 and the adjustment portion 3314, the distance between the second contact portion 3322 and the long spring piece 331 is the largest, which can provide a larger space for the second contact portion 3322 to avoid interference. In other embodiments, the second contact portion may not correspond to the angle between the extension portion and the adjustment portion in the width direction of the base portion.

[0046] The short spring piece 332 further includes a main body portion 3323 located between the second bending portion 3321 and the second contact portion 3322 , and the main body portion 3323 and the second bending portion 3321 have a smooth transition.

[0047] The overall length of the long spring piece 331 is greater than the overall length of the short spring piece 332, and the angle between the main body portion 3323 and the base portion 31 is greater than the angle between the extension portion 3313 and the base portion 31, the angle between the main body portion 3323 and the base portion 31 is smaller than the angle between the adjustment portion 3314 and the base portion 31, and the distance from the first contact portion 3312 to the base portion 31 is equal to the distance from the second contact portion 3322 to the base portion 31, and the first contact portion 3312 and the second contact portion 3322 are staggered in the width direction of the base portion 31.

[0048] After the first contact portion 3312 and the second contact portion 3322 are staggered in the width direction of the base portion 31, the shielding grounding spring 3 is bent, and the first contact portion 3312 and the second contact portion 3322 will not overlap or overlap in the length direction of the base portion 31, and the spacing between two adjacent first contact portions 3312 and the spacing between two adjacent second contact portions 3322 are large, which can allow the shielding grounding spring 3 to be bent to a greater extent, that is, the bent portion of the shielding grounding spring 3 can adapt to the smaller fillet on the socket. Moreover, the spacing between the long spring piece 331 and the short spring piece 332 in the length direction of the base portion 31 does not change, so the shielding effect of the shielding grounding spring 3 is not affected and can meet the use requirements.

[0049] Furthermore, the portion of the long spring piece 331 between the first bending portion 3311 and the first contact portion 3312 is divided into an extension portion 3313 and an adjustment portion 3314, so that the angle between the extension portion 3313 and the base portion 31 can be made smaller, thereby leaving more space for the movement of the long spring piece 331 and the short spring piece 332 when the shielding grounding spring 3 is bent, and being able to adapt to the smaller fillet at the position where the shielding grounding spring 3 is installed on the socket. Furthermore, since the angle between the adjustment portion 3314 and the base portion 31 is greater than the angle between the main body portion 3323 and the base portion 31, the distance between the first contact portion 3312 and the second contact portion 3322 in the width direction of the base portion 31 can be made smaller, making the shielding grounding spring 3 more compact.

[0050] In this embodiment, the first contact portion 3312 and the second contact portion 3322 are both straight structures. In other embodiments, the first contact portion 3312 and the second contact portion 3322 can also be processed into an arc structure to facilitate sliding cooperation with the plug.

[0051] Since the overall length of the long spring piece 331 is greater than the overall length of the short spring piece 332, there is still a lot of excess material on both sides of the first contact portion 3312 on the plate originally used to process the shielding grounding spring 3. When processing the shielding grounding spring 3, the first contact portion 3312 can be widened to increase the contact area between the first contact portion 3312 and the plug housing. Figure 6 and attached Figure 7, the first bending portion 3311, the extension portion 3313 and the adjustment portion 3314 are equally wide, that is, the dimensions in the length direction of the base portion 31 are equal, and the first contact portion 3312 is wider than the first bending portion 3311, the extension portion 3313 and the adjustment portion 3314, that is, the dimension of the first contact portion 3312 in the length direction of the base portion 31 is larger than the dimension of the first bending portion 3311, the extension portion 3313 and the adjustment portion 3314 in the length direction of the base portion 31. Compared with the prior art, the shielding grounding spring 3 has a larger contact area with the plug housing 2, so that better shielding and common grounding effects can be achieved.

[0052] In this embodiment, the long spring piece 331 is symmetrical about its symmetry plane, which is perpendicular to the length direction of the base portion, that is, the two ends of the first contact portion 3312 in the length direction of the base portion 31 protrude from the remaining portion of the long spring piece 331 by the same size. In other embodiments, the first contact portion may protrude only at one end in the length direction of the base portion.

[0053] Of course, in other embodiments, the first contact portion may not be widened, so that the size of the first contact portion in the length direction of the base portion is consistent with the sizes of the first bending portion, the extending portion and the adjusting portion in the length direction of the base portion.

[0054] Specific embodiment 2 of the connector assembly provided by the present invention: This embodiment is based on embodiment 1, and the difference from embodiment 1 is that, see attached Fig.11 In this embodiment, the first bending portion 3311 and the second bending portion 3321 are not aligned in the length direction of the substrate. Specifically, the bending curvature of the first bending portion 3311 is greater than the bending curvature of the second bending portion 3321, so that the first bending portion 3311 and the second bending portion 3321 are staggered along the bending radius. When the shielding grounding spring 3 is bent, the first bending portion 3311 and the second bending portion 3321 will not interfere with each other. Therefore, the shielding grounding spring 3 in this embodiment can bend to a greater extent.

[0055] Specific embodiment 3 of the connector assembly provided by the present invention: This embodiment is based on embodiment 1, and the difference from embodiment 1 is that, see attached Fig.12 In this embodiment, the portion of the long spring piece 331 between the first bending portion and the first contact portion 3312 is a straight portion 3315 of a straight structure. In this embodiment, the angle between the straight portion 3315 of the long spring piece 331 and the base portion 31 is smaller than the angle between the main body portion 3323 of the short spring piece 332 and the base portion 31. The distance from the first contact portion 3312 to the base portion 31 and the distance from the second contact portion 3322 to the base portion 31 can also be equal, and the first contact portion 3312 and the second contact portion 3322 are staggered in the width direction of the base portion 31.

[0056] Specific embodiment 4 of the connector assembly provided by the present invention: This embodiment is based on embodiment 1, and the difference from embodiment 1 is that, see attached Fig.13 In this embodiment, the portion of the long spring piece 331 between the first bending portion and the first contact portion 3312 is an arcuate portion 3316 of an arcuate structure, and the angle between the section of the arcuate portion 3316 near the first bending portion and the base portion 31 is smaller than the angle between the short spring piece 332 and the base portion 31, and the angle between the section of the arcuate portion 3316 away from the first bending portion and the base portion 31 gradually increases. In this embodiment, the distance from the first contact portion 3312 to the base portion 31 and the distance from the second contact portion 3322 to the base portion 31 can also be equal, and the first contact portion 3312 and the second contact portion 3322 are staggered in the width direction of the base portion 31.

[0057] Specific embodiment 5 of the connector assembly provided by the present invention: This embodiment is based on embodiment 1, and the difference from embodiment 1 is that, see attached Fig.14 In this embodiment, the angle between the main body portion 3323 and the base portion 31 is greater than the angle between the extension portion 3313 and the base portion 31, and the angle between the main body portion 3323 and the base portion 31 is equal to the angle between the adjustment portion 3314 and the base portion 31.
