Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to an elastic terminal. Background Art

[0002] A connector is provided between two electronic components, for example, between a circuit board and a circuit board, or between a circuit board and a chip module, to serve as a bridge for electrical connection. The connector includes an insulating plate and a terminal protruding from the insulating plate, with two ends of the terminal protruding from two sides of the insulating plate, respectively, so that the terminal is electrically conductive to the conductive parts of the two electronic components.

[0003] However, during assembly, that is, when the connector is assembled to two electronic components, the stress-strain strength of the connector is more important to ensure stable electrical connectivity. Prior art such as CN202585853U proposes an electrical connector, in which an elastic terminal includes a first fixed portion, a main elastic arm extending upwardly from the top of the first fixed portion and an auxiliary elastic arm extending from the first fixed portion toward the main elastic arm and located below the main elastic arm, and the auxiliary elastic arm can slide along the main elastic arm and support the main elastic arm when the main elastic arm is pressed down. The auxiliary elastic arm located below the main elastic arm and able to slide along the main elastic arm assists in providing support force. Regardless of whether the electrical connector is in contact with the chip module, the auxiliary elastic arm is always supported on the main elastic arm. Although it can improve the stress-strain characteristics, the width of the terminal is made narrower to save terminal material, so that the overall support strength of the elastic terminal is still weak and is not conducive to the transmission of high-frequency signals. Of course, if the width of the terminal is unilaterally increased to improve the support strength, the impedance of the elastic terminal will undoubtedly increase.

[0004] Therefore, there is an urgent need for an elastic terminal that can not only improve the overall supporting strength of the elastic terminal, but also reduce impedance and facilitate high-frequency signal transmission. Utility Model Content

Since the first wide conductive arm body is provided with a first through groove and the second wide conductive arm body is provided with a second through groove, the first through groove and the second through groove are arranged correspondingly, thereby reducing the impedance of the elastic terminal; since the first wide conductive arm body and the second wide conductive arm body are arranged opposite to each other, compared with the prior art, the width of the first wide conductive arm body and the width of the second wide conductive arm body are both wider, which not only improves the overall supporting strength of the elastic terminal, but also can reduce the impedance and is conducive to the elastic terminal for high-frequency signal transmission.

[0041] In order to better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below in conjunction with specific embodiments:

[0042] like Figures 1 to 4 As shown, an elastic terminal 10 of an embodiment includes a bending body 100, a first wide conductive arm body 200 and a second wide conductive arm body 300, the two ends of the bending body 100 are respectively connected to the first wide conductive arm body 200 and the second wide conductive arm body 300, the first wide conductive arm body 200 and the second wide conductive arm body 300 are both located on the same side of the bending body 100, and the first wide conductive arm body 200 and the second wide conductive arm body 300 are arranged opposite to each other. The first wide conductive arm body 200 is used to abut against the second wide conductive arm body 300 when under pressure. The first wide conductive arm body 200 is provided with a first through slot 202, and the second wide conductive arm body 300 is provided with a second through slot 204, and the first through slot 202 and the second through slot 204 are arranged correspondingly. In this embodiment, the first through groove 202 and the second through groove 204 are connected to each other, so that the elastic terminal 10 forms a pair of through hole groups in the Y-axis direction, reducing the facing area of ​​the first wide conductive arm body 200 and the second wide conductive arm body 300, thereby improving the impedance performance of the elastic terminal 10, that is, reducing the impedance of the elastic terminal 10.

[0043] In the above-mentioned elastic terminal 10, the two ends of the bending body 100 are respectively connected to the first wide conductive arm body 200 and the second wide conductive arm body 300, the first wide conductive arm body 200 and the second wide conductive arm body 300 are both located on the same side of the bending body 100, the first wide conductive arm body 200 and the second wide conductive arm body 300 are arranged opposite to each other, and the first wide conductive arm body 200 abuts against the second wide conductive arm body 300 when under pressure. Since the first wide conductive arm body 200 is provided with a first through groove 202, and the second wide conductive arm body 300 is provided with a second through groove 204, the first through groove 202 and the second through groove 204 are arranged correspondingly, thereby reducing the impedance of the elastic terminal 10; since the first wide conductive arm body 200 and the second wide conductive arm body 300 are arranged opposite to each other, compared with the prior art, the width of the first wide conductive arm body 200 and the width of the second wide conductive arm body 300 are both wider, which not only improves the overall supporting strength of the elastic terminal 10, but also can reduce the impedance and is conducive to the elastic terminal 10 for high-frequency signal transmission.

[0044] In order to better illustrate that the impedance performance of the elastic terminal 10 is better, the impedance performance tests are performed on the elastic terminal 10 of an embodiment and the elastic terminal 10 of the comparative example, wherein the elastic terminal 10 of the comparative example is an elastic terminal 10 without the first through slot 202 and the second through slot 204, and the impedance performance is obtained as follows: Figure 2 The impedance performance curve comparison diagram of the elastic terminal 10 of an embodiment and the elastic terminal 10 of a comparative example is shown. Figure 2 As shown, the impedance performance curve corresponding to the elastic terminal 10 of an embodiment is a, and the impedance performance curve corresponding to the elastic terminal 10 of the comparative example is b. Figure 2 It can be seen that the impedance performance of the elastic terminal 10 of an embodiment is significantly better than the impedance performance of the elastic terminal 10 of the comparative example.

[0045] like Figures 1 to 3 As shown, in one embodiment, the first wide conductive arm body 200 includes a wide holding section 200a, a first wide bending section 200b, a first wide floating section 200c, a first lower wide contact section 200d and a first upper wide contact section 200e connected in sequence, and the end of the wide holding section 200a away from the first wide bending section 200b is connected to one end of the bending body 100; the wide holding section 200a is used to be clamped on the insulating seat; the second wide conductive arm body 300 includes a wide vertical section 300a, a second wide bending section 300b, a second wide floating section 300c and a second wide contact section 300e connected in sequence, and the end of the wide vertical section 300a away from the second wide bending section 300b is connected to the other end of the bending body 100. The first through slot 202 is provided in the first wide floating section 200c, and the second through slot 204 is provided in the second wide floating section 300c; the first wide bending section 200b and the second wide bending section 300b are provided correspondingly. Figure 1 As shown, when the first upper wide abutment section 200e is in a free state, that is, when the first upper wide abutment section 200e is not pressed, the second wide abutment section 300e is located above the first lower wide abutment section 200d. At this time, there is a gap between the second wide abutment section 300e and the first lower wide abutment section 200d. Compared with the prior art, the space required for assembling the elastic terminal 10 on the insulating plate is smaller, thereby making the structure of the insulating plate more compact. Figure 4 As shown, when the first upper wide abutting section 200e is in a compressed state, the second wide abutting section 300e abuts against the first lower wide abutting section 200d, and the second wide abutting section 300e is electrically connected to the first lower wide abutting section 200d.

[0046] When in use, the elastic terminal 10 is assembled on the insulating board to form a connector. When the connector is not assembled between two electronic components, such as Figure 1 As shown, the first upper wide abutment section 200e is in a free state, and there is a gap between the second wide abutment section 300e and the first lower wide abutment section 200d; when the connector is assembled between two electronic components, as shown in FIG. Figure 4 As shown, the first upper wide abutting section 200e is in a compressed state, and the second wide abutting section 300e abuts against the first lower wide abutting section 200d.

[0047] like Figures 1 to 4 As shown, in one embodiment, the wide holding section 200a is provided with a third through slot 201, and the wide vertical section 300a is provided with a fourth through slot 203 corresponding to the third through slot 201, so that the elastic terminal 10 forms a pair of through hole groups in the X-axis direction, and the elastic terminal 10 forms a pair of through hole groups in the Y-axis direction, which further reduces the facing area of ​​the first wide conductive arm body 200 and the second wide conductive arm body 300, thereby further improving the impedance performance of the elastic terminal 10, that is, further reducing the impedance of the elastic terminal 10.

[0048] like Figures 1 to 4 As shown, in one embodiment, the width of the wide clamping section 200a along the first direction parallel to the first direction is greater than the width of the wide vertical section 300a along the first direction parallel to the first direction, which is beneficial to improve the impedance performance of the elastic terminal 10. In this embodiment, the first direction is parallel to the Z-axis direction, and the first direction is perpendicular to the Y-axis direction and the X-axis direction respectively.

[0049] like Figures 1 to 4 As shown, in one embodiment, the first direction is perpendicular to the deformation plane where the first wide conductive arm is located, so that the structure of the elastic terminal 10 is more compact. In this embodiment, the deformation plane where the first wide conductive arm is located is the XOY plane.

[0050] like Figures 1 to 4As shown, in one embodiment, the center line of the first wide conductive arm body and the center line of the second wide conductive arm body are both located in the deformation plane where the first wide conductive arm body is located, so that the second wide abutment section 300e can better abut against the first lower wide abutment section 200d when the first upper wide abutment section 200e is in a compressed state.

[0051] like Figure 1 As shown, in one embodiment, when the first upper wide abutting section 200e is in a free state, the wide clamping section 200a is arranged in parallel with the wide vertical section 300a, and the first wide floating section 200c is arranged in parallel with the second wide floating section 300c; Figure 4 As shown, when the first upper wide abutting section 200e is in a compressed state, the distance between the end of the wide vertical section 300a adjacent to the second wide bent section 300b and the wide clamping section 200a is greater than the distance between the end of the wide vertical section 300a away from the second wide bent section 300b and the wide clamping section 200a, so that the first lower wide abutting section 200d of the first wide conductive arm body abuts against the second wide abutting section 300e when under pressure, and at the same time saves the assembly space of the insulating plate of the connector in the X-axis direction and the Y-axis direction, avoiding interference between the second wide conductive arm body 300 and the insulating plate.

[0052] like Figures 1 to 5 As shown, in one embodiment, the width of the abutment portion of the first upper wide abutment section 200e is less than or equal to the width of the abutment portion of the second wide abutment section 300e, thereby improving the normal force of the elastic terminal 10, so that the first wide conductive arm 200 is better abutted against the second wide conductive arm 300, and further the first wide conductive arm 200 is better electrically connected to the second wide conductive arm 300. In this embodiment, the width of the abutment portion of the first upper wide abutment section 200e is less than the width of the abutment portion of the second wide abutment section 300e, thereby further improving the normal force of the elastic terminal 10.

[0053] In order to better verify that the width of the contact portion of the first upper wide contact section 200e is smaller than the width of the contact portion of the second wide contact section 300e, the positive force of the elastic terminal 10 is better. The positive force of Example 1 and Example 2 are tested below, wherein the width of the contact portion of the first upper wide contact section 200e of the conductive terminal of Example 1 is smaller than the width of the contact portion of the second wide contact section 300e, and the result is Figure 6 The positive force test curve of Example 1 is shown in FIG. The width of the contact portion of the first upper wide contact section 200e of the conductive terminal of Example 2 is equal to the width of the contact portion of the second wide contact section 300e, and the result is Figure 7 The positive force test curve of Example 2 is shown. Figure 6 and Figure 7It can be seen that the positive force of the conductive terminal of Example 1 is larger than that of the conductive terminal of Example 2.

[0054] like Figure 1 As shown, in one embodiment, the first through slot 202 extends to the first wide bending section 200b, and the second through slot 204 extends to the second wide bending section 300b, further reducing the facing area of ​​the first wide conductive arm body 200 and the second wide conductive arm body 300, thereby further improving the impedance performance of the elastic terminal 10, that is, further reducing the impedance of the elastic terminal 10.

[0055] like Figures 1 to 5 As shown, in one embodiment, the width of the first wide floating section 200c is greater than the width of the contact portion of the first upper wide contact section 200e; the width of the second wide floating section 300c is greater than the width of the contact portion of the second wide contact section 300e, so that the elastic terminal 10 has better overall supporting strength.

[0056] like Figures 1 to 5 As shown, in one embodiment, the bending body 100 is located at the bottom of the wide clamping section 200a and the wide vertical section 300a, and the bending part of the bending body 100 is provided with a cold implantation notch 102 for inserting the welding part, so that the welding part can be assembled by interference pressing through the cold implantation notch 102, and then welded to the PCB under the connector. In this embodiment, the welding part is a solder ball.

[0057] like Figures 1 to 5 As shown, in one embodiment, the wide holding section 200a is further provided with a fifth through slot 205, and the wide vertical section 300a is further provided with a sixth through slot 207 corresponding to the fifth through slot 205; the fifth through slot 205 and the sixth through slot 207 are both connected to the cold implantation slot 102, further reducing the facing area of ​​the first wide conductive arm body 200 and the second wide conductive arm body 300, thereby further improving the impedance performance of the elastic terminal 10, that is, further reducing the impedance of the elastic terminal 10.

[0058] like Figures 1 to 5 As shown, in one embodiment, two first clamping protrusions 208 are respectively provided on both sides of the wide clamping section 200a, and the two first clamping protrusions are arranged opposite to each other, so that the wide clamping section 200a is better clamped on the insulating plate. In this embodiment, a clamping slot is provided on the insulating plate. When the wide clamping section 200a is clamped into the clamping slot, the two first clamping protrusions on both sides of the wide clamping section 200a abut against the inner wall of the clamping slot.

[0059] like Figures 1 to 5As shown, in one embodiment, two second clamping protrusions 209 are respectively provided on both sides of the wide clamping section 200a, and the two second clamping protrusions are arranged opposite to each other; each second clamping protrusion is located below the corresponding first clamping protrusion, so that the wide clamping section 200a can be better clamped on the insulating plate.

[0060] Compared with the prior art, this application has at least the following advantages:

[0061] 1. In the above-mentioned elastic terminal 10, the two ends of the bending body 100 are respectively connected to the first wide conductive arm body 200 and the second wide conductive arm body 300, the first wide conductive arm body 200 and the second wide conductive arm body 300 are both located on the same side of the bending body 100, the first wide conductive arm body 200 and the second wide conductive arm body 300 are arranged opposite to each other, and the first wide conductive arm body 200 abuts against the second wide conductive arm body 300 when under pressure, because the first wide conductive arm body 200 is provided with a first through slot 202, and the second wide conductive arm body 300 is provided with a second through slot 204, the first through slot 202 and the second through slot 204 are arranged correspondingly, thereby reducing the impedance of the elastic terminal 10;

[0062] 2. Since the first wide conductive arm 200 and the second wide conductive arm 300 are arranged opposite to each other, compared with the prior art, the width of the first wide conductive arm 200 and the width of the second wide conductive arm 300 are both wider, which not only improves the overall supporting strength of the elastic terminal 10, but also can reduce the impedance and is conducive to the elastic terminal 10 for high-frequency signal transmission.
