Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a crimping terminal and a crimping connector. Background Art

[0002] A press-fit connector is a commonly used connector for communication between electronic devices. It utilizes press-fit terminals (i.e., press-fit contact terminals) to form effective electrical conduction with electronic devices such as printed circuit boards, enabling the transmission of electrical signals between the devices.

[0003] In the prior art, crimp connectors mainly include two types according to the difference in their crimping terminals. In one type of crimp connector, the crimping terminal is a solid terminal, which, after being inserted into an electronic device such as a printed circuit board, makes hard contact with the electronic device. In another type of crimp connector, the crimping terminal is a deformable terminal having an elastically deformable portion. For example, the crimping terminal is provided with a fisheye hole, and the two parts forming the fisheye hole are called elastic arms. When the crimping terminal is inserted into a plug hole such as a printed circuit board, the elastic arm undergoes elastic deformation and abuts against the hole wall of the plug hole, and the holding force of the crimping terminal comes from the force between the elastic arm and the hole wall of the plug hole.

[0004] It can be seen that the source of the retaining force of the crimping terminal in the prior art is relatively single, resulting in a small interaction force between the elastic arm and the hole wall of the plug-in hole, which in turn leads to a low connection reliability between the crimping terminal and electronic devices such as printed circuit boards. When used in electronic equipment with large vibration amplitudes, there is poor contact between the crimping terminal and the electronic device, affecting the continuity and stability of electrical signal transmission.

It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0041] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0042] Firstly, this embodiment provides a crimping terminal that can improve connection reliability, reduce the risk of poor contact, and thereby ensure the continuity and stability of electrical signal transmission.

[0043] like Figures 1 to 4As shown, the crimping terminal includes a main body 100, a pin portion 200, a first elastic portion 300, a second elastic portion 400, and an elastic support structure 500. Exemplarily, the crimping terminal is an integrated structure to provide high structural strength. The crimping terminal is made of a conductive material, such as metal. The crimping terminal can be inserted into a socket of a target electronic device, such as a printed circuit board, along a first direction X. The socket wall has a metal layer, such as copper, to enable both mechanical and electrical connection with the target electronic device.

[0044] The main body 100 is used to connect to a conductor, such as a wire. For example, the main body 100 can extend linearly along a first direction X. The pin portion 200 is spaced apart from the main body 100 in the first direction X and serves to guide insertion into the socket. Therefore, the pin portion 200 typically has a pointed end to facilitate insertion into the socket. The pin portion 200 can extend linearly along the first direction X. For example, the main body 100 and the pin portion 200 can be coaxially arranged to achieve a relatively symmetrical structure for the crimp terminal.

[0045] like Figure 1 As shown, the first elastic portion 300 is connected between the main body 100 and the pin portion 200. Specifically, one end of the first elastic portion 300 is connected to the end of the main body 100 toward the pin portion 200, and the other end of the first elastic portion 300 is connected to the end of the pin portion 200 toward the main body 100.

[0046] In this embodiment, the second elastic portion 400 is connected between the main body 100 and the pin portion 200 and is spaced apart from the first elastic portion 300 in the second direction Y. Specifically, one end of the second elastic portion 400 is connected to the end of the main body 100 facing the pin portion 200, and the other end of the second elastic portion 400 is connected to the end of the pin portion 200 facing the main body 100.

[0047] Furthermore, the first elastic portion 300 is capable of deforming at least in a second direction Y perpendicular to the first direction X so as to be in close contact with the wall of the plug hole. The second elastic portion 400 is capable of deforming at least in the second direction Y so as to be in close contact with the wall of the plug hole. Both the first elastic portion 300 and the second elastic portion 400 are capable of deforming in the second direction Y, so that the first elastic portion 300 can bulge toward one side of the second direction Y and the second elastic portion 400 can bulge toward the other side of the second direction Y. Figure 3In the figure, the first elastic portion 300 bulges toward the left side, while the second elastic portion 400 bulges toward the right side. The first and second elastic portions 300, 400 bulge simultaneously, cooperating with the main portion 100 and the pin portion 200 to form a fisheye hole 600. After the crimping terminal is inserted into the socket of the target electronic device, the first and second elastic portions 300, 400 are squeezed by the wall of the socket, allowing them to elastically deform toward each other in the second direction Y.

[0048] The elastic support structure 500 in this embodiment is used to support the first elastic portion 300 and the second elastic portion 400. Figure 1 As shown, the elastic support structure 500 is located between the first elastic portion 300 and the second elastic portion 400, and is connected to the first elastic portion 300 and the second elastic portion 400. Figure 4 As shown, the cross-section of the elastic support structure 500 perpendicular to the first direction X is V-shaped. That is, in any cross-section perpendicular to the first direction X, the central portion of the elastic support structure 500 in the second direction Y bulges toward the same side in the third direction Z. This facilitates elastic deformation of the elastic support structure 500, and the elastic support structure 500 can deform along with the deformation of the first elastic portion 300 and the second elastic portion 400, thereby providing elastic support for the first elastic portion 300 and the second elastic portion 400.

[0049] In this embodiment, Figure 2 As shown, the elastic support structure 500 includes a first end edge 510 facing the main body 100 and a second end edge 520 facing away from the main body 100, i.e., the second end edge 520 is arranged toward the pin portion 200. In this embodiment, the first end edge 510 and the second end edge 520 are the two end edges of the elastic support structure 500 in the first direction X. The first end edge 510 is at least partially recessed toward the pin portion 200, and the second end edge 520 is at least partially recessed toward the main body 100. This causes the length of the elastic support structure 500 in the first direction X to first decrease and then increase in the second direction Y, thereby causing the stiffness of the elastic support structure 500 in the second direction Y to first gradually increase and then gradually decrease. This allows for a smooth transition in the insertion force applied to the crimping terminal during insertion into the target device, generating a more ideal insertion force / insertion displacement curve, making the crimping terminal insertion process smoother.

[0050] The crimping terminal provided in this embodiment has an elastic support structure 500 provided between the first elastic part 300 and the second elastic part 400. After deformation, the elastic support structure 500 provides additional elastic force to the first elastic part 300 and the second elastic part 400, thereby increasing the holding force between the first elastic part 300 and the second elastic part 400 and the target electronic device after the crimping terminal is inserted into the target electronic device, that is, increasing the interaction force between the first elastic part 300 and the second elastic part 400 and the target electronic device, improving the reliability of the connection between the crimping terminal and the target electronic device, reducing the risk of poor contact between the crimping terminal and the target electronic device, and improving the continuity and stability of electrical signal transmission.

[0051] Furthermore, by setting the cross-sectional shape of the elastic support structure 500 perpendicular to the first direction X to a V-shape, compared to setting it to other shapes, the insertion force required to overcome the deformation of the first elastic part 300 and the second elastic part 400 when the crimping terminal is inserted into the target electronic device can be reduced, which facilitates insertion while also improving the supporting force. The angle of the V-shaped elastic support structure 500 can also be quickly adjusted to obtain crimping terminals with different specifications of insertion force and holding force, so that the distance between the first elastic part 300 and the second elastic part 400 can be quickly adjusted, and a one-type-for-multiple-purposes structure can be quickly derived in terms of structural development. For example, the elastic support structure 500 includes Figure 3 The left and right parts are connected at an arc chamfered position to improve the structural strength of the elastic support structure 500 and reduce the probability of the elastic support structure 500 breaking.

[0052] Alternatively, as Figure 1 As shown, the elastic support structure 500 is provided with a crimping terminal having an elastic support structure 500. While ensuring the connection reliability and stability, the structure is relatively simple, so that the structure of the stamping die used for stamping to form the crimping terminal can be relatively simple, and the stamping manufacturing process can also be relatively simple, so that the manufacturing effect and yield can be greatly improved.

[0053] Further optionally, the elastic support structure 500 is connected to the middle portion of the first elastic portion 300 in the first direction X and the middle portion of the second elastic portion 400 in the first direction X. Since the middle portions of the first elastic portion 300 and the second elastic portion 400 abut against the hole wall of the plug hole, arranging the elastic support structure 500 to be connected to the middle portions of the first elastic portion 300 and the second elastic portion 400 can specifically support the portions of the first elastic portion 300 and the second elastic portion 400 that contact the target electronic component, thereby improving the stability and retention of the contact between the crimping terminal and the target electronic component.

[0054] When there is one elastic support structure 500, the elastic support structure 500 is arranged in the fisheye hole 600, such as Figure 3 As shown, the fisheye hole 600 is separated into a first through hole 610 and a second through hole 620. That is, the first through hole 610 and the second through hole 620 are separated by the elastic support structure 500. The provision of the first through hole 610 and the second through hole 620, on the one hand, reduces the overall weight of the crimping terminal, facilitating the miniaturization of the crimping terminal. On the other hand, compared to a solid structure, the insertion force required to overcome the deformation of the elastic support structure 500 when inserting the crimping terminal into the target electronic device is reduced, thereby facilitating the connection of the crimping terminal. In this embodiment, the first through hole 610 is closer to the main body 100 than the second through hole 620.

[0055] For example, Figure 3 As shown, the first end edge 510 includes a first plane 511 and a second plane 512. The first plane 511 and the second plane 512 are arranged at an angle. The provision of the first plane 511 and the second plane 512 facilitates the processing and manufacturing of the first end edge 510, thereby facilitating the molding of the elastic support structure 500. Furthermore, the provision of the first plane 511 and the second plane 512 allows the central portion of the elastic support structure 500 to be smaller in the first direction X than a curved surface. Alternatively, from another perspective, the edge region of the elastic support structure 500 connecting the first elastic portion 300 and the second elastic portion 400 can be larger in the first direction X. This not only ensures a smooth transition of the insertion force, but also increases the connection area between the elastic support structure 500 and the first elastic portion 300 and the second elastic portion 400. This allows the retention force to be applied to more areas of the first elastic portion 300 and the second elastic portion 400, thereby increasing the contact area between the first elastic portion 300 and the second elastic portion 400 and the wall of the plug hole, thereby improving contact reliability and stability.

[0056] Optionally, the first plane 511 and the second plane 512 can be connected with a first curved surface 513. By setting the first curved surface 513, the first plane 511 and the second plane 512 can have a smooth transition, thereby improving the strength of the connection between the part where the first plane 511 of the elastic support structure 500 is located and the part where the second plane 512 is located, and further reducing the risk of the elastic support structure 500 breaking.

[0057] Similar to the first end edge 510, Figure 3As shown, the second end edge 520 includes a third plane 521 and a fourth plane 522, and the third plane 521 is arranged at an angle to the fourth plane 522. The provision of the third plane 521 and the fourth plane 522 facilitates the processing and manufacturing of the second end edge 520, further facilitating the molding of the elastic support structure 500, and further increasing the contact area between the elastic support structure 500 and the first elastic portion 300 and the second elastic portion 400, thereby further improving the support effect.

[0058] For example, a second arc surface 523 may be connected between the third plane 521 and the fourth plane 522 . The second arc surface 523 has similar beneficial effects to the first arc surface 513 , and this embodiment will not be described in detail.

[0059] In some optional embodiments, the fisheye hole 600 in this embodiment is a polygonal hole, that is, the hole wall of the fisheye hole 600 is composed of multiple planes. By providing the fisheye hole 600 with a polygonal structure, the size of the fisheye hole 600 can be larger, thereby increasing the deformation range of the first elastic part 300 and the second elastic part 400, making it suitable for a variety of plug-in holes of different sizes, thereby improving the versatility of the crimping terminal.

[0060] The fisheye hole 600, the first through hole 610, the second through hole 620 and the elastic support structure 500 in this embodiment are all axially symmetrical structures with a symmetry axis, so that the force applied to the first elastic part 300 and the second elastic part 400 can be more uniform, thereby ensuring that the first elastic part 300 and the second elastic part 400 can better contact the hole wall of the plug hole, and the contact area is increased, which can also reduce the resistance.

[0061] Alternatively, as Figure 5 As shown, the first elastic portion 300 includes a first wall 311 and a second wall 312, which are arranged in the axial direction of the first elastic portion 300. The second elastic portion 400 includes a third wall 411 and a fourth wall 412, which are arranged in the axial direction of the second elastic portion 400. The first wall 311 and the third wall 411 are arranged at an angle to each other, and the second wall 312 and the fourth wall 412 are arranged at an angle to each other. In addition, the first wall 311, the third wall 411, the first plane 511 and the second plane 512 are used to enclose a first through hole 610, and the second wall 312, the fourth wall 412, the third plane 521 and the fourth plane 522 are used to enclose a second through hole 620.

[0062] In this embodiment, the first wall surface 311, the second wall surface 312, the third wall surface 411 and the fourth wall surface 412 are all planes, so that the first wall surface 311, the second wall surface 312, the third wall surface 411, the fourth wall surface 412, the first plane 511, the second plane 512, the third plane 521 and the fourth plane 522 are all planes, which facilitates the transmission of force. Figure 4 and Figure 5 As shown, after the crimped terminal is subjected to force, the direction of force transmission is Figure 5 The dotted line with an arrow in the middle enables the crimped terminal to obtain more reliable retention force. For example, the failure risk in environmental tests such as thermal shock can be improved.

[0063] In some optional embodiments, please continue to see Figure 3 The angle between the first wall 311 and the third wall 411 is a1, and the angle between the first plane 511 and the second plane 512 is b1, where b1>a1. By setting the angle between the first wall 311 and the third wall 411 to be greater than the angle between the first plane 511 and the second plane 512, the holding force of the crimp terminal can be further improved.

[0064] Similarly, the angle between the second wall 312 and the fourth wall 412 is a2, and the angle between the third plane 521 and the fourth plane 522 is b2, where b2>a2. By setting the angle between the second wall 312 and the fourth wall 412 greater than the angle between the third plane 521 and the fourth plane 522, the holding force of the crimp terminal is further improved.

[0065] In some optional embodiments, a2 and a1 are both acute angles, and b1 and b2 can be acute angles, obtuse angles, or right angles.

[0066] Optionally, a2=a1, b1=b2, so that the first elastic part 300 and the second elastic part 400 can be subjected to more uniform force, so that the first elastic part 300 and the second elastic part 400 can better abut against the hole wall of the plug hole to ensure the contact effect.

[0067] For example, please see Figure 3 The first elastic portion 300 further includes a fifth wall 313 connected between the first wall 311 and the second wall 312. The second elastic portion 400 further includes a sixth wall 413 connected between the third wall 411 and the fourth wall 412.

[0068] Among them, the first plane 511 intersects with the first wall 311, and the intersection position of the first plane 511 and the first wall 311 is different from the intersection position of the first wall 311 and the fifth wall 313; the second plane 512 intersects with the third wall 411, and the intersection position of the second plane 512 and the third wall 411 is different from the intersection position of the third wall 411 and the sixth wall 413; the third plane 521 intersects with the second wall 312, and the intersection position of the third plane 521 and the second wall 312 is different from the intersection position of the second wall 312 and the fifth wall 313; the fourth plane 522 intersects with the fourth wall 412, and the intersection position of the fourth plane 522 and the fourth wall 412 is different from the intersection position of the fourth wall 412 and the sixth wall 413. In this way, on the one hand, the dimensions of the two ends of the elastic support structure 500 can be larger to ensure the connection effect; on the other hand, it ensures that the angle between the first plane and the second plane and the angle between the third plane and the fourth plane will not be too large, thereby improving the overall holding force of the crimping terminal.

[0069] In some optional embodiments, such as Figure 3 As shown, the fifth wall surface 313 and the sixth wall surface 413 may also be planes. Of course, it is understandable that the fifth wall surface 313 and the sixth wall surface 413 may also not be planes, and this embodiment does not limit this.

[0070] Alternatively, as Figure 4 As shown, the first elastic portion 300 has a first side surface 320 and a second side surface 330 that are arranged opposite each other in the third direction Z. The distance between the connection point between the elastic support structure 500 and the first elastic portion 300 and the first side surface 320 is L1, and the distance between the connection point between the elastic support structure 500 and the first elastic portion 300 and the second side surface 330 is L2, where L1 is less than L2, and the middle portion of the elastic support structure 500 extends toward the second side surface 330. Arranging the connection point between the elastic support structure 500 and the first elastic portion 300 offset from the middle portion of the first elastic portion 300 in the third direction Z allows the elastic support structure 500 to have a larger range of motion in the third direction Z and does not extend beyond the fisheye hole 600. Furthermore, the dimensions of the elastic support structure 500 in the first direction X, the second direction Y, and the third direction Z can all be made larger to ensure sufficient supporting force and deformation amplitude.

[0071] Similarly, the second elastic portion 400 has a third side surface and a fourth side surface that are disposed opposite each other in the third direction Z. The distance between the connection point between the elastic support structure 500 and the second elastic portion 400 and the third side surface is greater than the distance between the connection point and the fourth side surface.
