Description

Technical Field

[0001] The utility model relates to a spacer connection structure of an electrical connector, belonging to the technical field of electrical signal transmission equipment. Background Art

[0002] At present, with the increase of the power density and transmission rate of high-speed connectors, the intervals between the signal lines inside the connectors are getting smaller and smaller, resulting in more and more serious interference between the internal signal lines. The signals inside the high-speed connectors are mainly differential signals, and a ground is arranged between adjacent differential signals for isolation. For example, as shown in FIG. 1, the differential pairs are isolated by the ground to reduce the mutual influence.

[0003] The design of high-speed signal channels should not only ensure the integrity and continuity of the signal path, but also ensure the integrity and continuity of the signal return path (i.e., the ground path). The discontinuity and incompleteness of the signal path or the signal return path will lead to a sharp deterioration of the electrical performance. Due to the requirements of the characteristic impedance, insertion loss, and return loss of high-speed connectors, the continuity and integrity of the signal path will be focused on and optimized. However, for the further improvement of the electrical performance of high-speed connectors, it is also necessary to focus on optimizing the integrity and continuity of the signal return path.

For this purpose, the utility model proposes a spacer connection structure of an electrical connector, in which the spacers serving as ground conductors are spliced in parallel, which can improve the continuity and integrity of the signal return path of the electrical connector.

[0037] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present utility model in combination with the embodiments and the drawings, so as to fully understand the purpose, solution and effects of the present utility model. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

In addition, the descriptions such as up, down, left, right, top, bottom, etc. used in the present utility model are only relative to the mutual positional relationship of the various components of the present utility model in the drawings.

[0039] In addition, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present technology. The terms used in the description of this specification are only for describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any combination of one or more of the related listed items.

[0040] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from each other. For example, without departing from the scope of this disclosure, the first element may also be referred to as the second element, and similarly, the second element may also be referred to as the first element.

[0041] See Figure 1a , Figure 1b and Figures 2 to 11 , the spacer connection structure of the electrical connector of the technical solution of the present utility model includes a first spacer 100 and a second spacer 200 that are ground conductors of the electrical connector 500. The first spacer 100 is provided with a first bending portion 110 for contacting the second spacer 200. It can be understood that when the first spacer 100 and the second spacer 200 are in a contact state, the first spacer 100 is disposed above the second spacer 200, or the first spacer 100 is disposed below the second spacer 200.

[0042] In the spacer connection structure of the electrical connector of the present utility model, the first spacer 100 and the second spacer 200 serve as ground conductors of the electrical connector 500 and act as signal return paths, which is beneficial to ensuring the integrity and continuity of the high-speed signal channel. And the first spacer 100 is provided with a first bending portion 110 for contact connection. Thus, when the plug and the socket are matingly connected, the first spacer 100 and the second spacer 200 adopt a spacer parallel splicing method to achieve a mating transition, which is beneficial to ensuring the parallel contact of the two spacers in a narrow space and ensuring the continuity and integrity of the signal return path.

[0043] See Figure 1a, the electrical connector 500 includes a plug assembly 510 and a socket assembly 520. The plug assembly 510 is connected to the socket assembly 520 to achieve signal transmission. Specifically, the plug assembly 510 is used to connect the transmission cable 512. One end of the conductive member 511 in the plug assembly 510 is connected to the transmission cable 512. The socket assembly 520 is used to connect the circuit board 522. The circuit board 522 is connected to the pad member 521 in the socket assembly 520. The plug assembly 510 is inserted into the socket assembly 520, and the other end of the conductive member 511 is connected to the pad member 521, thereby achieving signal transmission. Among them, referring to Figure 2 , the two contacts of the circuit board 522 as a differential pair are respectively connected to one end of two conductive members 511 (as a group of conductive members 511). Two signal lines serving as a group of differential line pairs are provided in the transmission cable 512. The other ends of the two conductive members 511 are respectively connected to the two signal lines in the transmission cable 512.

[0044] Referring to Figure 1a , Figure 1b , Figure 5 and Figure 8 , partitions are provided inside both the plug assembly 510 and the socket assembly 520. For example, a first partition 100 and a fourth partition 400 are provided inside the plug assembly 510. The first partition 100 is perpendicular to the fourth partition 400, and a plurality of fourth partitions 400 are connected to one first partition 100. A second partition 200 and a third partition 300 are provided inside the socket assembly 520. The second partition 200 is perpendicular to the third partition 300, and a plurality of third partitions 300 are connected to one second partition 200. When the plug assembly 510 is inserted into the socket assembly 520, the first partition 100 contacts the second partition 200, and the third partition 300 contacts the fourth partition 400, forming an independent space that acts as a shield. Each group of conductive members 511 is respectively arranged in an independent space, which can form an enclosure and separation of the conductive members 511, playing a good role in shielding interference. It can be understood that the first partition 100 and the second partition 200 can be made of metal, and the third partition 300 and the fourth partition 400 can be made of metal. It should be noted that it is also possible to have a second partition 200 and a fourth partition 400 provided inside the plug assembly 510 and a first partition 100 and a third partition 300 provided inside the socket assembly 520. The above combinations are only for illustrative purposes.

[0045] The partition connection structure of the electrical connector of the present utility model uses a metal plane to act as the signal return path, which is a better solution to ensure its integrity and continuity. Moreover, using a metal plane, that is, a metal partition, to isolate each pair of differential signals can further ensure that there is no mutual interference between the differential pair signals on the basis of ensuring the integrity and continuity of the signal return path.

[0046] It should be noted that since the socket and plug of the high-speed connector are discrete components, in the existing electrical connector structure, a slotted notch (i.e., a bevel is provided at the end of the spacer) is used for mating connection between the plug spacer and the socket spacer. Although the slotted notch structure is simple, it has very high requirements for assembly tolerances and there is a relatively high risk that the slotted notch cannot be touched. When the plug assembly 510 and the socket assembly 520 are mated in the present utility model, the first spacer 100 and the second spacer 200 are spliced in parallel, which is beneficial to ensure the integrity and continuity of the mating between the plug metal plane and the socket metal plane, thereby improving the continuity and integrity of the entire signal return path.

[0047] In some embodiments, the first spacer 100 includes a plate body and a first bending portion 110. The first bending portion 110 is provided at the end of the plate body. Specifically, referring to Figures 3 to 5 , the first bending portion 110 is on the outer side of the plate body. When the plug assembly 510 is inserted into the socket assembly 520, the first bending portion 110 will contact the outer end of the second spacer 200, so that the signal return path is connected. It can be understood that the first spacer 100 has elasticity. When the plug assembly 510 is inserted into the socket assembly 520, the first bending portion 110 undergoes elastic deformation, enabling the second spacer 200 to be inserted smoothly, and the first spacer 100 abuts against the second spacer 200, which is beneficial to improving the connection reliability. Further, the second spacer 200 has elasticity. When the first spacer 100 and the second spacer 200 are in contact, the second spacer 200 can also undergo elastic deformation. It can be understood that one, two or more first bending portions 110 can be provided.

[0048] In some embodiments, the first bending portion 110 includes a first bend 111 and a second bend 112, and the openings of the first bend 111 and the second bend 112 are opposite to each other. For example, referring to Figure 1a 、 Figure 1b and Figure 7 , the second bend 112 is on the outer side of the first bend 111. When the plug assembly 510 is in the state of being inserted into the socket assembly 520, the opening of the first bend 111 faces the second spacer 200, and the opening of the second bend 112 faces away from the second spacer 200, that is, the first bend 111 is recessed in the direction away from the second spacer 200, and the second bend 112 is recessed in the direction close to the second spacer 200. It should be noted that it can also be set that the openings of the first bend 111 and the second bend 112 are the same. Further, the first bending portion 110 can be provided with multiple bends, and the openings of any two bends are the same or opposite.

[0049] In some embodiments, the second spacer 200 is provided with a chamfer position 210 for contacting the first spacer 100. The chamfer position 210 plays a guiding role and facilitates the insertion of the spacers. Further, the outer end of the second spacer 200 is provided with a chamfer position 210, and the end of the first bending portion 110 is correspondingly inclined, so as to guide the contact between the first spacer 100 and the second spacer 200. For example, see Figure 3 , the first spacer 100 is above the second spacer 200. In the state where the plug assembly 510 is inserted into the socket assembly 520, the end of the second bending position 112 is inclined from the inside out in a direction away from the second spacer 200, and the chamfer position 210 at the end of the second spacer 200 is inclined from the inside out in a direction away from the first spacer 100. Thus, the inclined extension directions of the second bending position 112 and the chamfer position 210 cooperate with each other, which facilitates the insertion of the plug assembly 510 into the socket assembly 520 and realizes parallel contact between the two spacers.

[0050] In some embodiments, two first spacers 100 are provided, and the two first spacers 100 are allowed to contact the opposite sides of the second spacer 200 respectively. For example, see Figure 4 , when the plug assembly 510 is inserted into the socket assembly 520, the two first spacers 100 are respectively arranged on both sides of the second spacer 200, and the two first spacers 100 respectively abut against the left side and the right side of the end of the second spacer 200. It can be understood that the two first bending portions 110 are symmetrically arranged on both sides of the second spacer 200. Further, chamfer positions 210 can be provided on both sides of the end of the second spacer 200. When the plug assembly 510 is inserted into the socket assembly 520, the two first bending portions 110 respectively contact the two chamfer positions 210. It can be understood that the two chamfer positions 210 are symmetrically arranged, and the inclination direction of each chamfer position 210 matches the inclination direction of the end of the first bending portion 110 in contact therewith, so as to facilitate the insertion of the spacers. It should be noted that when provided on the two first spacers 100, only one of the first spacers 100 can be provided with a first bending position, and the other first spacer 100 does not have a first bending position structure.

[0051] In some embodiments, the thickness of the first spacer 100 is the same as that of the second spacer 200, which is beneficial to simplifying the production process and improving production efficiency. In some embodiments, see Figure 3 and Figure 6 , the thicknesses of the first spacer 100 and the second spacer 200 are different, so that the degrees of elastic deformation occurring when the two spacers contact are different, which is beneficial to improving the contact reliability.

[0052] In some embodiments, the second spacer 200 is provided with a second bending portion for contacting the first spacer 100. Further, the structure of the second bending portion is the same as that of the first bending portion 110. Specifically, the inclination direction of the outer end of the second bending portion matches that of the first bending portion 110, so that the first bending portion 110 can be inserted incidentally when contacting the second bending portion. For example, the second bending portion is provided with a third bending position and a fourth bending position with opposite opening directions, and the fourth bending position is outside the third bending position. When the plug assembly 510 is inserted into the socket assembly 520, the opening of the third bending position faces the first spacer 100, and the opening of the fourth bending position faces away from the first spacer 100, that is, the third bending position is recessed away from the first spacer 100, and the fourth bending position is recessed towards the first spacer 100, and the fourth bending position can contact the second bending position 112. It can be understood that the second bending portion can be provided with one, two or more.

[0053] In some embodiments, the spacer splicing structure of the electrical connector 500 of the present invention further includes a third spacer 300 and a fourth spacer 400 that allow a signal loop to be formed with the first spacer 100 and the second spacer 200. The third spacer 300 is provided with a first bending portion 110 for contacting the fourth spacer 400. It should be noted that the third spacer 300 can be disposed in the plug assembly 510 and the fourth spacer 400 can be disposed in the socket assembly 520, or the third spacer 300 can be disposed in the socket assembly 520 and the fourth spacer 400 can be disposed in the plug assembly 510. It can be understood that the first spacer 100 can be used to connect multiple third spacers 300 and the second spacer 200 can be used to connect multiple fourth spacers 400, or the first spacer 100 can be used to connect multiple fourth spacers 400 and the second spacer 200 can be used to connect multiple third spacers 300.

[0054] See Figure 1a and Figure 1b , when the plug assembly 510 is inserted into the socket assembly 520, the first spacer 100 contacts the second spacer 200, and the third spacer 300 contacts the fourth spacer 400. In the spacer mechanism of the electrical connector 500 of the present invention, the structure of the first bending portion 110 at the end of the third spacer 300 is the same as that of the first bending portion 110 at the end of the first spacer 100. The third spacer 300 and the fourth spacer 400 are spliced in parallel, which is beneficial to ensuring the integrity and continuity of the cooperation between the plug metal plane and the socket metal plane, and improving the continuity and integrity of the entire signal return path.

[0055] It can be understood that, see Figures 6 to 8The structure of the contact between the third separator 300 and the fourth separator 400 may be the same as the structure of the contact between the first separator 100 and the second separator 200. Specifically, the end of the fourth separator 400 may also be provided with a chamfer 210 matching the first bending portion 110, or the end of the fourth separator 400 may also be provided with a second bending portion. Further, the thickness of the third separator 300 and the fourth separator 400 is the same, or the thickness of the third separator 300 and the fourth separator 400 is different.

[0056] In some embodiments, see Figures 8 to 10 The first spacer 100 or the second spacer 200 is provided with a notch 220 that allows the third spacer 300 and the fourth spacer 400 to be misaligned at the contact point. When the plug assembly 510 is inserted into the socket assembly 520, the third spacer 300 contacts the fourth spacer 400 at the notch 220. The notch 220 reserves a space that allows misalignment at the contact point, which is conducive to achieving close contact between the third spacer 300 and the fourth spacer 400, and ensuring the continuity and integrity of the signal path.

[0057] Here is a specific example to illustrate. Figure 1a , Figure 1b and Figure 9 The plug assembly 510 is provided with a first spacer 100 and a plurality of fourth spacers 400, the first spacer 100 is provided with a first bending position, and the fourth spacers 400 are all provided with a chamfered position 210, and the socket assembly 520 is provided with a second spacer 200 and a plurality of third spacers 300, the second spacer 200 is provided with a chamfered position 210, and the third spacers 300 are all provided with a first bending portion 110, and a notch 220 is provided on the second spacer 200. Specifically, the second spacer 200 is provided with a plurality of connection grooves 230, the openings of the connection grooves 230 face upward, and a notch 220 is provided in the middle of each connection groove 230. The third spacer 300 is provided with a slot 310, and the slot 310 opens downward. When the third spacer 300 is inserted into the second spacer 200, the second spacer 200 is in the slot 310, and one third spacer 300 is in one connection groove 230, and the first bending portion 110 of the third spacer 300 is in the notch 220. One side of the plurality of fourth spacers 400 is clamped in the first spacer 100, and the end of the fourth spacer 400 protrudes from the first spacer 100.

[0058] See also Figure 9 and Figure 10, when the plug assembly 510 is inserted into the socket assembly 520, the lower end of the fourth spacer 400 enters the connection groove 230 and contacts the end of the third spacer 300 at the notch 220. At this time, the end of the first spacer 100 contacts the end of the second spacer 200. Among them, when the third spacer 300 and the fourth spacer 400 just contact and there is no pressure between them, the third spacer 300 and the fourth spacer 400 do not contact the inner wall of the notch 220. When the third spacer 300 and the fourth spacer abut and there is pressure between them, the first spacer 100 and the second spacer 200 can be misaligned in the notch 220 to achieve the tight fit of the third spacer 300 and the fourth spacer 400, which can reduce or even eliminate the gap between the spacers and improve the electrical performance of the electrical connector 500.

[0059] In some specific embodiments, for example, referring to Figure 10 and Figure 11 , when the third spacer 300 is provided with a first bending portion 110, the fourth spacer 400 is provided with a matching chamfer position 210, and the third spacer 300 is located below the fourth spacer 400, the side of the notch 220 for accommodating the first spacer 100 is of a quasi-rectangular structure, so as to allow the first bending position 111 and the second bending position 112 to enter the notch 220 and allow the first bending portion 110 to undergo elastic deformation in the notch 220. The side of the notch 220 for accommodating the fourth spacer 400 is of a quasi-rectangular structure, and a convex block 221 for abutting against the lower end of the fourth spacer 400 is provided below this side of the notch 220. When the operator presses the plug assembly 510 into the socket assembly 520 so that the third spacer 300 and the fourth spacer 400 abut and are misaligned, when the operator further applies force to increase the elastic deformation of the spacer, the end of the fourth spacer 400 will contact the convex block 221, which plays a role in preventing further misalignment between the third spacer 300 and the fourth spacer 400, thereby reducing the damage to the electrical connector 500 caused by improper operation.
