Description

Technical Field

[0001] This invention belongs to the field of electrical connectors, and in particular relates to a shielded grounding spring, a connector, and a connector assembly. Background Technology

[0002] The shielding grounding spring provides shielding and forms a common ground between the housings of the connector and the adapter connector. The shielding grounding spring is formed from a metal sheet using a progressive die, and after forming... Figure 1 As shown, it is a long strip. During assembly, cut the shielding grounding spring to the required length, then refer to the appendix. Figure 2 and attached Figure 3 The operator manually bends the shielding grounding spring 3 according to the shape of the connector housing (e.g., socket housing 1) and inserts the shielding grounding spring 3 into the connector housing with the ends grounded. After being inserted 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 portion 31, a spring piece 33 located on one side of the base portion 31 in the width direction, and a mounting foot 32 located on the other side of the base portion 31 in the width direction. The end of the spring piece 33 away from the base portion 31 is a contact portion for sliding and pressing against the housing of the adapter connector. The contact portion extends out on one side in the thickness direction of the base portion. The spring pieces 33 are arranged at intervals along the length direction of the base portion 31. When the shielding grounding spring 3 is bent, the spring pieces 33 are located inside the base portion 31. At the bending point, the spring pieces 33 of the shielding grounding spring 3 are prone to overlapping and splicing.

[0004] Spring overlap refers to the interference between adjacent springs, especially at the contact point, during the bending process of the shielding grounding spring. This prevents the shielding grounding spring from bending into place effectively. Consequently, the base of the bent part of the shielding grounding spring cannot be tightly attached to the connector shell during assembly, making it impossible to weld the shielding grounding spring firmly to the connector shell and increasing the risk of the shielding grounding spring falling off during use.

[0005] Spring overlap refers to the deformation of the spring at the bent part when the shielding grounding spring is forcibly bent, causing part or all of the contact part of the spring to lift up and fail to make contact with the shell of the adapter connector. On the one hand, this results in a small contact area between the shielding grounding spring and the shell of the adapter connector, which is difficult to meet the shielding requirements; on the other hand, the spring at the bent part is not subjected to uneven force, which poses a greater risk of breakage during use.

[0006] Increasing the spacing between the springs of the shielding grounding spring can prevent the springs from overlapping and splicing at the bends, but increasing the spacing between the springs will result in a poorer shielding effect, making it difficult to meet the usage requirements. Summary of the Invention

[0007] One of the objectives of this invention is to provide a shielded grounding spring to solve the technical problems in the prior art where the shielded grounding spring is prone to overlapping and splicing of the spring pieces after bending, resulting in the shielded grounding spring being difficult to bend into place, poor shielding effect, and uneven force on the spring pieces.

[0008] One of the objectives of this invention is to provide a connector to solve the aforementioned technical problems.

[0009] One of the objectives of this invention is to provide a connector assembly to solve the aforementioned technical problems.

[0010] To achieve the above objectives, the technical solution of the shielded grounding spring provided by this invention is as follows:

[0011] A shielding grounding spring includes a sheet-like base portion and a plurality of spring sheets spaced apart along the length direction of the base portion. The spring sheets are all connected to the same side in the width direction of the base portion. The ends of the spring sheets away from the base portion are contact portions for sliding and pressing against the housing of an adapter connector. The contact portions of the spring sheets extend out to the same side in the thickness direction of the base portion. The spring sheets include alternating short spring sheets and long spring sheets. The contact portions of the short spring sheets and the contact portions of the long spring sheets are staggered along the width direction of the base portion so that when the shielding grounding spring is installed in the housing of the connector, the contact portions of the long spring sheets and the contact portions of the short spring sheets do not interfere with each other at the bend.

[0012] As a further improvement, the long spring includes an extension and an adjustment portion bent at one end of the extension. The contact portion of the long spring is located at the end of the adjustment portion away from the extension, and the angle between the extension and the base portion is smaller than the angle between the adjustment portion and the base portion.

[0013] As a further improvement, the short spring includes a main body, the contact portion of the short spring is located at one end of the main body, and the angle between the main body and the base is greater than the angle between the extension portion and the base and less than the angle between the adjustment portion and the base.

[0014] As a further improvement, the contact portion of the short spring corresponds to the bending angle between the extension portion and the adjustment portion in the width direction of the base portion.

[0015] As a further improvement, the dimension of the contact portion of the long spring in the length direction of the base portion is larger than the dimension of the rest of the long spring in the length direction of the base portion.

[0016] As a further improvement, the long spring is symmetrical about its symmetry plane, which is perpendicular to the length direction of the base portion.

[0017] As a further improvement, the end of the reed used to connect with the base is a bend formed by an arc bend, and the bends of each reed are aligned in the length direction of the base.

[0018] As a further improvement, the end of the spring used to connect with the base is a bend formed by an arc bend. The bending rate of the bend of the long spring is greater than that of the bend of the short spring, so that the bend of the long spring and the bend of the short spring do not interfere with each other when the shielding grounding spring is installed in the housing of the connector.

[0019] The beneficial effects are as follows: The shielding grounding spring provided by this invention is an improvement on the prior art. Based on the prior art, this invention divides the spring into alternating short and long springs, and staggers the contact portions of the short and long springs in the width direction of the base. This does not affect the good contact between the contact portions of the short and long springs and the adapter connector housing. Furthermore, when the shielding grounding spring needs to be bent to install it in the connector housing, the contact portions of the short and long springs will not overlap or lap, allowing the shielding grounding spring to bend to a greater extent and ensuring it is bent and installed correctly. Since adjacent springs do not interfere with or compress each other, it also prevents the springs from breaking due to uneven stress. Moreover, the shielding grounding spring provided by this invention does not require changing the spacing between adjacent springs, thus ensuring a good shielding effect.

[0020] To achieve the above objectives, the technical solution for the connector provided by this invention is as follows:

[0021] A connector includes a housing and a shielding grounding spring mounted within the housing. The shielding grounding spring includes a sheet-like base portion and a plurality of spring plates spaced apart along the length of the base portion. The spring plates are all connected to the same side in the width direction of the base portion. The ends of the spring plates away from the base portion are contact portions for sliding and pressing against the housing of the adapter connector. The contact portions of the spring plates extend outward from the same side in the thickness direction of the base portion. The spring plates include alternating short spring plates and long spring plates. The contact portions of the short spring plates and the contact portions of the long spring plates are staggered along the width direction of the base portion so that the contact portions of the long spring plates and the contact portions of the short spring plates do not interfere with each other when the shielding grounding spring is installed in the housing of the connector.

[0022] As a further improvement, the long spring includes an extension and an adjustment portion bent at one end of the extension. The contact portion of the long spring is located at the end of the adjustment portion away from the extension, and the angle between the extension and the base portion is smaller than the angle between the adjustment portion and the base portion.

[0023] As a further improvement, the short spring includes a main body, the contact portion of the short spring is located at one end of the main body, and the angle between the main body and the base is greater than the angle between the extension portion and the base and less than the angle between the adjustment portion and the base.

[0024] As a further improvement, the contact portion of the short spring corresponds to the bending angle between the extension portion and the adjustment portion in the width direction of the base portion.

[0025] As a further improvement, the dimension of the contact portion of the long spring in the length direction of the base portion is larger than the dimension of the rest of the long spring in the length direction of the base portion.

[0026] As a further improvement, the long spring is symmetrical about its symmetry plane, which is perpendicular to the length direction of the base portion.

[0027] As a further improvement, the end of the reed used to connect with the base is a bend formed by an arc bend, and the bends of each reed are aligned in the length direction of the base.

[0028] As a further improvement, the end of the spring used to connect with the base is a bend formed by an arc bend. The bending rate of the bend of the long spring is greater than that of the bend of the short spring, so that the bend of the long spring and the bend of the short spring do not interfere with each other when the shielding grounding spring is installed in the housing of the connector.

[0029] The beneficial effects are as follows: The connector provided by this invention is an improvement on the prior art. Based on the prior art, this invention divides the shielding grounding spring into alternating short and long springs, and staggers the contact portions of the short and long springs in the width direction of the base. This does not affect the good contact between the contact portions of the short and long springs and the matching connector housing. Furthermore, when the shielding grounding spring needs to be bent to install it in the connector housing, the contact portions of the short and long springs will not overlap or lap, allowing the shielding grounding spring to bend to a greater extent and ensuring it is bent and installed correctly. Since adjacent springs do not interfere with or compress each other, it also prevents the springs from breaking due to uneven stress. Moreover, the shielding grounding spring provided by this invention does not require changing the spacing between adjacent springs, thus ensuring a good shielding effect.

[0030] To achieve the above objectives, the technical solution for the connector assembly provided by this invention is as follows:

[0031] A connector assembly includes a male connector and a female connector. A shielding grounding spring is provided within the housing of one of the male and female connectors. The shielding grounding spring includes a sheet-like base portion and a plurality of spring plates spaced apart along the length of the base portion. The spring plates are all connected to the same side in the width direction of the base portion. The ends of the spring plates away from the base portion are contact portions for sliding and pressing against the housing of the mating connector. The contact portions of the spring plates extend outwards from the same side in the thickness direction of the base portion. The spring plates include alternating short spring plates and long spring plates. The contact portions of the short spring plates and the contact portions of the long spring plates are staggered along the width direction of the base portion so that when the shielding grounding spring is installed inside the housing of the connector, the contact portions of the long spring plates and the contact portions of the short spring plates do not interfere with each other at bends.

[0032] As a further improvement, the long spring includes an extension and an adjustment portion bent at one end of the extension. The contact portion of the long spring is located at the end of the adjustment portion away from the extension, and the angle between the extension and the base portion is smaller than the angle between the adjustment portion and the base portion.

[0033] As a further improvement, the short spring includes a main body, the contact portion of the short spring is located at one end of the main body, and the angle between the main body and the base is greater than the angle between the extension portion and the base and less than the angle between the adjustment portion and the base.

[0034] As a further improvement, the contact portion of the short spring corresponds to the bending angle between the extension portion and the adjustment portion in the width direction of the base portion.

[0035] As a further improvement, the dimension of the contact portion of the long spring in the length direction of the base portion is larger than the dimension of the rest of the long spring in the length direction of the base portion.

[0036] As a further improvement, the long spring is symmetrical about its symmetry plane, which is perpendicular to the length direction of the base portion.

[0037] As a further improvement, the end of the reed used to connect with the base is a bend formed by an arc bend, and the bends of each reed are aligned in the length direction of the base.

[0038] As a further improvement, the end of the spring used to connect with the base is a bend formed by an arc bend. The bending rate of the bend of the long spring is greater than that of the bend of the short spring, so that the bend of the long spring and the bend of the short spring do not interfere with each other when the shielding grounding spring is installed in the housing of the connector.

[0039] The beneficial effects are as follows: The connector assembly provided by this invention is an improvement on the prior art. Based on the prior art, this invention divides the shielding grounding spring into alternating short and long springs, and staggers the contact portions of the short and long springs in the width direction of the base. This does not affect the good contact between the contact portions of the short and long springs and the matching connector housing.

Moreover, the shielding grounding spring provided by this invention does not require changing the spacing between adjacent springs, thus ensuring a good shielding effect. Attached Figure Description

[0056] The present invention will be further described in detail below with reference to the embodiments.

[0057] To address the problems in the prior art, the basic concept of this invention is to change the shape of the reeds so that the ends of the reeds are staggered along the width of the base, so that during the bending process of the shielding grounding spring, the parts of adjacent reeds that are far from the base will not interfere with each other, thereby enhancing the bending ability of the shielding grounding spring.

[0058] Specific embodiment 1 of the connector assembly provided by the present invention:

[0059] A connector assembly, see attached Figure 4 and attached Figure 5 It includes 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 conductive metal shell. During the plug-socket insertion process, the end of the plug shell 2 needs to be inserted into the end of the socket shell 1.

[0060] A shielding grounding spring 3 is provided inside the plug housing 2. This spring connects the housings of the plug and socket to a common ground after the plug and socket are inserted, thus providing shielding between them. In this embodiment, the socket is a connector for mounting the shielding grounding spring 3, and the plug is an adapter connector for the socket.

[0061] See appendix Figure 6 and attached Figure 7 The shielding grounding spring 3 includes a base portion 31, a spring piece 33 connected to one side of the base portion 31 in the width direction, and a mounting foot 32 connected to the other side of the base portion 31 in the width direction. The spring piece 33 and the mounting foot 32 are evenly spaced along the length direction of the base portion 31. (See attached diagram.) Figure 5 The inner side of the socket connector is provided with an annular inner protrusion 11, and the locking pin 32 is bent into a U-shape. During assembly, the locking pin 32 is locked on the outer side of the inner protrusion 11, so that the inner protrusion 11 provides a limit for the locking pin 32 in the insertion and removal direction of the plug and socket. The specific structure of the locking pin 32 is the same as that of the prior art, and will not be described in detail here.

[0062] To install the shielding grounding spring 3 into the socket, the operator needs to bend the shielding grounding spring 3. The final bending shape of the shielding grounding spring 3 can be determined based on the shape of the insertion hole on the socket housing 1, for example, as shown in the attached diagram. Figure 8 Waist and appendage Figure 9 In other embodiments, the shielding grounding spring 3 can also be bent into a rounded rectangle, with the bent spring 33 located inside the base portion 31.

[0063] See appendix Figure 6 and attached Figure 7 and in conjunction with the appendix Figure 10 The spring 33 includes a long spring 331 and a short spring 332, which are arranged alternately along the length of the base portion 31. The two ends of the long spring 331 and the short spring 332 are respectively a bent portion and a contact portion. The bent portion is the end of the long spring 331 and the short spring 332 that connects to the base portion 31, and is formed by an arc-shaped bending process. The contact portion is the end of the long spring 331 and the short spring 332 that is away from the base and is used for sliding and pressing against the plug housing 2. The bent portions allow each contact portion to extend to the same side in the thickness direction of the base portion 31. The bent portion of the long spring 331 is a first bent portion 3311, and the bent portion of the short spring 332 is a second bent portion 3321; the contact portion of the long spring 331 is a first contact portion 3312, and the contact portion of the short spring 332 is a second contact portion 3322. The first bending portion 3311 and the second bending portion 3321 are aligned along the length of the base material to facilitate bending processing.

[0064] The long spring 331 also includes an extension 3313 and an adjustment portion 3314 located between the first bent portion 3311 and the first contact portion 3312. One end of the extension 3313 is connected to the first bent portion 3311, and the other end of the extension 3313 is connected to the adjustment portion 3314. The end of the adjustment portion 3314 away from the extension 3313 is connected to the first contact portion 3312. The extension 3313 and the first bent portion 3311 have a smooth transition, and the junction of the extension 3313 and the adjustment portion 3314 is an angled structure, so that an angle greater than 0° and less than 180° is formed between the extension 3313 and the adjustment portion 3314. The second contact portion 3322 corresponds to the angle between the extension portion 3313 and the adjusting portion 3314 in the width direction of the base portion 31. At the angle between the extension portion 3313 and the adjusting portion 3314, the distance between the second contact portion 3322 and the long spring 331 is the largest, providing more 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 adjusting portion in the width direction of the base portion.

[0065] The short spring 332 also includes a main body 3323 located between the second bending portion 3321 and the second contact portion 3322, with the main body 3323 smoothly transitioning to the second bending portion 3321.

[0066] The overall length of the long spring 331 is greater than the overall length of the short spring 332, and the angle between the main body 3323 and the base 31 is greater than the angle between the extension 3313 and the base 31. The angle between the main body 3323 and the base 31 is less than the angle between the adjustment part 3314 and the base 31. The distance from the first contact part 3312 to the base 31 is equal to the distance from the second contact part 3322 to the base 31. The first contact part 3312 and the second contact part 3322 are offset in the width direction of the base 31.

[0067] After the first contact portion 3312 and the second contact portion 3322 are offset in the width direction of the base portion 31, the shielding grounding spring 3 is bent. The first contact portion 3312 and the second contact portion 3322 do not overlap or lap in the length direction of the base portion 31. The spacing between two adjacent first contact portions 3312 and the spacing between two adjacent second contact portions 3322 are large, which allows for a large degree of bending of the shielding grounding spring 3. That is, the bent part of the shielding grounding spring 3 can adapt to smaller rounded corners 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. Therefore, the shielding effect of the shielding grounding spring 3 is not affected and can meet the usage requirements.

[0068] Furthermore, dividing the long spring 331, including the portion located between the first bending portion 3311 and the first contact portion 3312, into an extension portion 3313 and an adjustment portion 3314 allows for a smaller angle between the extension portion 3313 and the base portion 31. This provides more space for the movement of the long spring 331 and the short spring 332 when the shielding grounding spring 3 bends, accommodating smaller rounded corners at the location where the shielding grounding spring 3 is installed on the socket. Moreover, 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 smaller, making the shielding grounding spring 3 more compact.

[0069] In this embodiment, both the first contact portion 3312 and the second contact portion 3322 are straight structures. In other embodiments, the first contact portion 3312 and the second contact portion 3322 can also be processed into arc-shaped structures, which makes it easier to slide and fit with the plug.

[0070] Because the overall length of the long spring 331 is greater than that of the short spring 332, there is still a considerable amount of excess material on both sides of the first contact portion 3312 on the original sheet metal used to manufacture the shielded grounding spring 3. When manufacturing the shielded 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. See the attached image for the finished shielded grounding spring 3. Figure 6 and attached Figure 7 The first bending portion 3311, the extension portion 3313, and the adjustment portion 3314 are all of equal width, meaning their dimensions along the length of the base portion 31 are equal. However, 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 first contact portion 3312 is larger along the length of the base portion 31 than the first bending portion 3311, the extension portion 3313, and the adjustment portion 3314. Compared to the prior art, this shielding grounding spring 3 has a larger contact area with the plug housing 2, thus achieving better shielding and grounding effects.

[0071] In this embodiment, the long spring 331 is symmetrical about its symmetrical plane, which is perpendicular to the length direction of the base portion. That is, the two ends of the first contact portion 3312 protruding from the rest of the long spring 331 in the length direction of the base portion are of equal size. In other embodiments, the first contact portion may protrude only at one end in the length direction of the base portion.

[0072] Of course, in other embodiments, the first contact portion may not be widened, so that the dimension of the first contact portion in the length direction of the base portion is consistent with the dimension of the first bent portion, the extension portion and the adjustment portion in the length direction of the base portion.

[0073] Specific embodiment 2 of the connector assembly provided by the present invention:

[0074] This embodiment is based on Embodiment 1, and the difference between it and Embodiment 1 is as follows: see Appendix Figure 11 In this embodiment, the first bent portion 3311 and the second bent portion 3321 are not aligned in the length direction of the base. Specifically, the bending rate of the first bent portion 3311 is greater than that of the second bent portion 3321, thereby causing the first bent portion 3311 and the second bent portion 3321 to be offset along the bending radius. When the shielding grounding spring 3 is bent, the first bent portion 3311 and the second bent portion 3321 will not interfere with each other. Therefore, the shielding grounding spring 3 in this embodiment can tolerate a greater degree of bending.

[0075] Specific embodiment 3 of the connector assembly provided by the present invention:

[0076] This embodiment is based on Embodiment 1, and the difference between it and Embodiment 1 is as follows: see Appendix Figure 12In this embodiment, the portion of the long spring 331 located between the first bent portion and the first contact portion 3312 is a straight portion 3315 with a straight structure. In this embodiment, the angle between the straight portion 3315 of the long spring 331 and the base portion 31 is smaller than the angle between the main body portion 3323 of the short spring 332 and the base portion 31. Alternatively, the distance from the first contact portion 3312 to the base portion 31 can be equal to the distance from the second contact portion 3322 to the base portion 31. The first contact portion 3312 and the second contact portion 3322 are offset in the width direction of the base portion 31.

[0077] Specific embodiment 4 of the connector assembly provided by the present invention:

[0078] This embodiment is based on Embodiment 1, and the difference between it and Embodiment 1 is as follows: see Appendix Figure 13 In this embodiment, the portion of the long spring 331 located between the first bend and the first contact portion 3312 is an arc-shaped portion 3316. The angle between the tangent of the arc-shaped portion 3316 near the first bend and the base portion 31 is smaller than the angle between the short spring 332 and the base portion 31. The angle between the tangent of the arc-shaped portion 3316 away from the first bend and the base portion 31 gradually increases. In this embodiment, the distance from the first contact portion 3312 to the base portion 31 can also be 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 can be offset in the width direction of the base portion 31.

[0079] Specific embodiment 5 of the connector assembly provided by the present invention:

[0080] This embodiment is based on Embodiment 1, and the difference between it and Embodiment 1 is as follows: see Appendix Figure 14 In this embodiment, the angle between the main body 3323 and the base 31 is greater than the angle between the extension 3313 and the base 31, and the angle between the main body 3323 and the base 31 is equal to the angle between the adjustment part 3314 and the base 31. This allows the distance from the first contact part 3312 to the base 31 to be equal to the distance from the second contact part 3322 to the base 31. The first contact part 3312 and the second contact part 3322 are offset in the width direction of the base 31.

[0081] Specific embodiment 6 of the connector assembly provided by the present invention:

[0082] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the spring in this embodiment does not have a bent portion. In this embodiment, the position where the base part is connected to the spring part is bent so that the contact part of the spring part can be suspended to one side of the thickness direction of the base part.

[0083] Specific embodiment 1 of the connector provided by the present invention:

[0084] The connector is a socket in any of the embodiments 1-6 of the connector assembly described above, and the plug constitutes an adapter connector for the connector, which will not be described in detail here.
