Description

Terminal assembly of electrical connector and electrical connector structure

The present invention relates to a terminal assembly of an electrical connector and an electrical connector structure.

Signals in various electronic devices are mainly transmitted to each other through many electronic connectors. Generally speaking, electronic connectors are mainly composed of insulating shells and most metal terminals. With the development of technology, the amount of information to be transmitted by electronic devices is increasing, so it is necessary to increase the transmission frequency or speed of signals.

As the transmission frequency or speed of the electronic connector is higher, the energy of the high-frequency signal is also prone to loss during the transmission process. This loss includes conductor loss and dielectric loss. In addition, if a conductor that transmits high-frequency electronic signals has an unclosed (ie, open) terminal, the unclosed terminal will have discontinuous impedance, thereby reducing the signal integrity of the high-frequency signal transmission path, which is generally referred to as residual stub effect.

The problem of the stub effect of the existing high-speed connectors is partly caused by the mutual mating of the male and female connectors. In order to ensure that the contact between the two connectors is stable, there must be scratches between the terminals of the mating male and female connectors ( wiping), then when the two matched connectors exchange high-frequency electronic signals with each other, the unavoidable scratches will cause the terminals to have unclosed terminals, resulting in a stub effect to reduce the integrity of high-frequency signal transmission. The stub effect will negatively affect the complete transmission of the signal.

Please refer to FIG. 1 and FIG. 2 , the electrical connector structure 50 of this embodiment includes an insulating housing 52 and a terminal assembly 100 , and the connector structure 50 is integrally disposed on a circuit board (not shown in the figure). )superior. For a general high-frequency electrical connector, it is uneconomical to use only one terminal assembly 100 for a connector. Usually, a high-frequency electrical connector can use at least two terminal assemblies, and even a specific high-density electrical connector can be used. To four terminal components, for example, the signal contacts in the QSFP DD (Quad Small Form-factor Pluggable Double Density) standard specification are arranged on two opposite surfaces of an electronic card (not shown in the figure), and each Two rows of signal contacts are arranged on the surface, so there are four rows of signal contacts on the electronic card. At this time, the connector can use four or more terminal assemblies, and each terminal assembly is along a direction perpendicular to the insertion direction of the electronic card. arranged in layers in the direction. From this, it can be seen that although the connector structure 50 disclosed in the present invention only uses one terminal assembly 100, this is only an example, the terminal assembly 100 used in the connector is determined according to the actual needs, and the disclosure in this specification is only for the purpose of Simplified illustration for the purpose of simplifying the level of complexity of the disclosure. For example, the insulating case 52 is made of insulating material. Although the insulating case 52 in this embodiment only includes a slot 54 for inserting a predetermined mated electronic card, the slot 54 can accommodate a mated electronic card. The card is inserted along an insertion direction Z1, but the number of the connector slots 54 can be adjusted according to requirements. The terminal assemblies are stacked and arranged along an arrangement direction Z2 perpendicular to the insertion direction Z1 of the electronic card.

In this embodiment, the terminal assembly 100 includes an insulating body 110 and a plurality of terminals 120 and 130 . The terminals 120 and 130 are fixed to the insulating body 110 , and the terminals 120 and 130 are electrically connected to each other. In this embodiment, the portion of each terminal 120 extending from the first end 112 of the insulating body 110 is used for electrical connection with the electronic card (printed circuit board or integrated circuit board) that is connected to the insulating body 110 , and the portion extending from the first end 112 of the insulating body 110 The terminals 130 of the extending portion of the two ends 114 can be used for electrical connection with the circuit board not shown. Specifically, each of the terminals shown in the figures is an embodiment suitable for being attached to the surface of the circuit board, however, the practical application of the present invention is not limited to this.

As shown in FIGS. 3 to 4, each terminal 120 includes a terminal body 122 and a cantilever section 124 composed of a first cantilever section A1, a second cantilever section A2, and a third cantilever section A3. The first cantilever section A1, The second cantilever section A2 and the third cantilever section A3 are jointly connected to the same terminal body 122 . In detail, the terminal body 122 is bent and extended in a height direction V (for example, downward, pointing toward the electronic card 60 ) to form the three first cantilever sections A1 , the second cantilever sections A2 and the third cantilever sections A3 , wherein the first cantilever section A1 is located between the second cantilever section A2 and the third cantilever section A3. As shown in FIG. 3 , compared with the second cantilever section A2 and the third cantilever section A3 , the bending angle between the first cantilever section A1 and the terminal body 122 is smaller, resulting in the first cantilever section A1 in the scratching direction (that is, the linear direction L in Figure 4) and the second cantilever segment A2 and the third cantilever segment A3 are located at different positions (that is, the scraping length of the first cantilever segment A1 in the scraping stroke when docked is the same as the second cantilever segment A3. A2 and the third cantilever segment A3 are different).

The first cantilever segment A1 includes a bending part A11, a contact part A13 and an end part A15; the second cantilever segment A2 includes a bending part A21, a contact part A23 and an end part A25; the third cantilever segment A3 includes a bending part A31, a contact part A25 part A33 and end part A35. In a linear direction L of the terminal body 122 (that is, in this embodiment, the terminal 120 and the electronic card 60 mated to match the scratching direction), the first cantilever section A1, the second cantilever section A2, and the third cantilever section A3 extend out respectively. Correspondingly a bending part A11, A21, A31, a contact part A13, A23, A33 and a terminal part A15, A25, A35, and each contact part A13, A23, A33 is connected to the corresponding terminal part A15, A25 , A35 and between the bending parts A11, A21 and A31. In the height direction V, with the terminal body 122 as the reference point for comparison, the positions of the end portions A15, A25, A35 and the contact portions A13, A23, and A33 are all lower than the terminal body 122, and the heights of the end portions A15, A25, and A35 are all lower than the terminal body 122. Higher than the heights of the contact portions A13, A23, and A33, that is, the contact portions A13, A23, and A33 are the lowest points of the first cantilever section A1, the second cantilever section A2, and the third cantilever section A3. The shapes of the contact portions A13, A23, and A33 are, for example, an arc shape, a U shape, or a V shape. In this embodiment, there are at least two different distances between the end portions A15 , A25 , A35 and the terminal body 122 . Taking FIG. 5 as an example, the distance between the end portion A15 of the first cantilever segment A1 and one side of the terminal body 122 is There is a first distance D1 between them, a second distance D2 between the end A25 of the second cantilever segment A2 and one side of the terminal body 122, and a distance between the end A35 of the third cantilever segment A3 and one side of the terminal body 122 There is a third distance D3 between them. The first distance D1 is greater than the second distance D2 or the third distance D3, and the second distance D2 is equal to the third distance D3, that is, the length of the first cantilever section A1 in this embodiment along the linear direction L of the terminal body 122 is greater than The length of the second cantilever section A2 or the third cantilever section A3. In other embodiments, the second distance D2 may not be equal to the third distance D3, and the lengths of the three cantilever segments can be adjusted depending on the actual product. It should be noted that, since the terminals 120 in the same row may include transmitting high and low electronic signals, in one embodiment, the above-mentioned terminals 120 with the contact portions A13, A23, and A33 are, for example, used for transmitting high-frequency electronic signals. The terminals for transmitting low-frequency electronic signals can be additionally configured.

In this embodiment, as shown in Figs. 3 and 6, the contact portion A13 of the first cantilever segment A1, the contact portion A23 of the second cantilever segment A2, and the contact portion A33 of the third cantilever segment A3 are respectively used to communicate with When the same signal contact 62 of an electronic card 60 is docked (when scratched, the cantilever segments A1, A2, A3 of the terminals 120 respectively exert a positive force on the signal contact 62), the contact parts A13, A23, A33 are Contact with the same signal contact 62 on the electronic card 60 corresponding to the position of the terminal 120 . The contact portions A13 , A23 , and A33 are located at different positions on the same horizontal plane of the signal contact 62 , and the contact portions A13 , A23 , and A33 are located at different positions in the linear direction L that contact the signal contact 62 . A single terminal 120 has a plurality of contact points for the signal contact 62, and these contact points are located at different positions in the linear direction L of the signal contact 62. As shown in FIG. 6, the signal contact 62 includes an initial contact position GS, The first contact position P1 and the second contact position P2. The initial contact position GS is the starting position of each contact portion of the terminal 120 (such as the contact portions A31 and A33 in FIG. 6 ) scratching on the signal contact 62 , and the end position after scratching is defined as the first contact position P1 , the second contact position P2, wherein the contact portion A13 is at the first contact position P1 on the signal contact 62, and the contact portion A33 is at the second contact position P2 of the signal contact 62. Similarly, the contact portion A23 is at the signal contact 62. The upper contact position may be a third contact position different from the first contact position P1 and the second contact position P2, or may be a position equivalent to one of the first contact position P1 or the second contact position P2. A distance GD is formed between the first contact position P1 and the initial contact position GS of the signal contact 62 , and a distance GW is formed between the second contact position P2 and the initial contact position GS of the signal contact 62 . The closed terminal distance is reduced from the distance GD to the distance GW, so that the unclosed terminals in the metal conductor are reduced, thereby suppressing the stub effect, reducing the electromagnetic interference to the surrounding environment, and improving the signal integrity of the high-frequency signal path. It should be noted that, the electronic card 60 is in contact with the contact portion A13 of the first cantilever segment A1, the contact portion A23 of the second cantilever segment A2, and the third cantilever segment by the signal contacts 62 on the same surface of the electronic card 60. The contact part A33 of A3 is used as an illustration. However, in other embodiments, the signal contacts can be arranged on two opposite surfaces of the electronic card, and each signal contact arranged on the opposite two surfaces of the electronic card is respectively connected by at least one terminal assembly The contact parts (eg, the contact part A13 of the first cantilever segment A1 , the contact part A23 of the second cantilever segment A2 , and the contact part A33 of the third cantilever segment A3 ) are electrically connected.

Taking FIG. 7 as a comparative example, FIG. 7 is a side view of a conventional terminal, wherein the conventional terminal 70 has a connecting section 72 and a contact portion 74 , the connecting section 72 is connected to the contact portion 74 , and the contact portion 74 is in the The signal contact 62 has a contact position P0 , and the contact position P0 is the end position of the contact portion 74 after being scratched on the signal contact 62 . Since the length of the signal contact 62 is limited by a certain specification, a distance GD is formed between the contact position P0 and the initial contact position GS of the signal contact 62 , and this GD distance is the scratch of the contact portion 74 on the signal contact 62 Wiping length, this distance GD will cause impedance discontinuity due to the reduction of impedance due to capacitive effect during signal transmission. The signal is continuously reflected in this path to weaken the original signal strength, resulting in a stub effect, reducing the high frequency of the terminal itself. Signal integrity of signal delivery.

As shown in Fig. 8, in terms of the insertion loss analysis calculated by simulation, the sample 1 is an electrical connector with some technologies in Fig. 7, and the sample 2 is an electrical connector structure 50 with the present invention, wherein the unit of abscissa is is gigahertz (GHz), the ordinate unit is decibel (dB), the line L1 is the simulation curve of the insertion loss of the sample one, and the line L2 is the simulation curve of the insertion loss of the sample two. It can be seen from this figure that in the frequency bands above 22 gigahertz (GHz), the decibel of line L1 has exceeded -3dB after 25 gigahertz (GHz), and the decibel after 35 gigahertz (GHz) has exceeded -3dB. The decibel has reached -5dB; in contrast, in the present invention, the decibel of the line L2 between 22 gigahertz (GHz) and 35 gigahertz (GHz) can be maintained below -3db. It can be seen from this that at the same 22 GHz, the present invention for solving the stub effect is beneficial to signal integrity transmission, that is, the high-frequency signal transmitted by the terminal 120 has less signal attenuation, so the present invention is at least in The signal transmission of all frequency bands above 22 gigahertz (GHz) is significantly improved. For example, at 40 GHz, the decibel of line L2 is greater than that of line L1, which means that the signal attenuation of line L2 is less in this case. Furthermore, compared with the first resonance point PL1 (about 48 GHz) of the line L1 of the prior art, the second resonance point PL2 (about 57 GHz) of the line L2 also moves to the high frequency by nearly 10 kilohertz. As many megahertz (GHz), the structure shown in Figure 6 in this case has a wide operating range (0~57 GHz), and is not prone to signal attenuation at relatively high frequencies. Therefore, the present invention is indeed used to effectively improve the problem of energy loss on the high-frequency signal transmission path, thereby increasing the transmission bandwidth and speed of the electrical connector.
