Description

Technical Field

[0001] This invention relates to the field of data transmission technology, and more particularly to a connector and an electronic device. Background Technology

[0002] Connectors are used to connect different electronic components to enable signal transmission between them. With continuous technological advancements, modern network servers and supercomputers are processing data at increasingly faster speeds. Application-Specific Integrated Circuits (ASICs) use serial differential signaling links to transmit ultra-high-speed data, reaching speeds of up to hundreds of Gbps. On complex, high-density printed circuit boards (PCBs), it is increasingly difficult to find wiring space that meets the requirements of high-speed differential data transmission. Therefore, precision cable connectors are needed to directly transmit the high-speed differential signals from ASICs to the required devices. The performance of the cable connector has a crucial impact on the quality of signal transmission, and even affects its integrity. In related technologies, connectors connect the cable and contacts on the circuit board. The contacts in the connector's socket contact the signal contacts on the circuit board, and the contacts in the connector's plug connect to the cable. The contacts in the socket and plug interlock, making it difficult to achieve stable and reliable signal transmission. Summary of the Invention

[0003] This invention is based on the inventor's discoveries and understanding of the following facts and problems:

[0004] To improve the stability and reliability of signal transmission, the applicant of this application proposed that the elastic contact inside the plug is connected to the cable and makes direct elastic contact with the signal contacts on the circuit board, thereby improving the stability and reliability of signal transmission.

[0005] Through further research, the inventors discovered and realized that because the elastic contacts of the connector and the signal contacts on the circuit board make elastic contact through mechanical force, and both the signal contacts on the circuit board and the elastic contacts of the connector are generally made of copper, the exposed copper will form an oxide film upon contact with air, affecting the reliability and stability of the connection. To prevent oxidation of the elastic contacts and the signal contacts on the circuit board, surface treatment (such as gold plating or immersion gold) is required for both. The inventors realized that while gold plating or immersion gold plating is relatively easy for individual small components, it is complex, costly, and difficult to perform on circuit boards with a large number of contacts.

[0006] The present invention aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, an embodiment of the first aspect of the present invention provides a connector that is easy to surface treat, low in cost, and has high stability and reliability in contact and signal transmission.

[0008] A second aspect of the present invention provides an electronic device having the aforementioned connector.

[0009] A connector according to a first aspect of the present invention includes a resilient contact and an intermediate contact, the intermediate contact being adapted to be directly or indirectly soldered to signal contacts on a circuit board, the resilient contact having a wiring segment and a resilient contact segment, the wiring segment of the resilient contact being adapted to be connected to a cable, the resilient contact segment of the resilient contact being in resilient contact with the intermediate contact to form an electrical connection, and at least the contact portions of the intermediate contact and the resilient contact that are in contact with each other being surface treated to form an anti-oxidation layer.

[0010] In the connector of this invention, the intermediate contact and the elastic contact are in elastic contact, and the intermediate contact is soldered to the circuit board. During surface treatment, only small components need to be treated, avoiding surface treatment of the circuit board with many contacts. This makes the connector easy to surface treat and reduces the cost of surface treatment, thereby improving the stability and reliability of connector contact and signal transmission. Furthermore, the connector of this invention is relatively easy to use.

[0022] In some embodiments, the elastic contact is integrally formed from an elastic metal sheet, and the contact surface of at least one of the first contact portion, the second contact portion, and the third contact portion is a curved surface, and the shape of the contact portion of the intermediate contact member that contacts the second contact portion is adapted to the shape of the second contact portion.

[0025] In some embodiments, the connector further includes a connecting sleeve that is fitted over the first contact portion and the third contact portion to constrain the first contact portion and the third contact portion.

[0026] In some embodiments, the main body shape of the elastic contact segment is any one of a circle, ellipse, O-shape, C-shape, W-shape, and S-shape, and the partial shape of the elastic contact segment is one or more of a circle, ellipse, O-shape, C-shape, W-shape, and S-shape.

[0051] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0052] This invention is based on the inventor's discoveries and understanding of the following facts and problems:

[0053] To improve the stability and reliability of signal transmission, the applicant of this application proposed that the elastic contact inside the plug is connected to the cable and makes direct elastic contact with the signal contacts on the circuit board, thereby improving the stability and reliability of signal transmission.

[0054] Through further research, the inventors discovered and realized that because the elastic contact of the connector and the signal contact on the circuit board are in elastic contact through mechanical force, the organic film on the elastic contact and the organic film on the signal contact on the circuit board will detach under the action of mechanical force, exposing the elastic contact and the signal contact on the circuit board to the air. The material of the signal contact on the circuit board and the elastic contact of the connector is generally copper. The contact between the exposed copper and the air will form an oxide film, affecting the reliability and stability of the connection.

[0055] To prevent oxidation of the elastic contacts and signal contacts on the circuit board, surface treatment (such as gold plating or immersion gold) is required to form a strong anti-oxidation film on the surface of the elastic contacts and circuit board.

[0056] The inventors realized that elastic contacts are small, individual parts, and it is relatively easy to perform gold plating or immersion gold surface treatment. However, the gold plating or immersion gold surface treatment process for circuit boards with many contacts is complex, costly, and difficult.

[0057] The connectors and electronic devices according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0058] The electronic device of this invention includes: a circuit board 6, a cable, and a connector; the inner conductor of the cable is connected to an elastic contact 2, and the intermediate contact 1 is soldered to a signal contact 61 on the circuit board 6.

[0059] In the electronic device of this invention, the intermediate contact and the elastic contact are in elastic contact, and the intermediate contact is soldered to the circuit board. During surface treatment, only small components need to be treated, avoiding surface treatment of the circuit board with many contacts. This makes the electronic device easy to surface treat and reduces the cost of surface treatment, thereby improving the stability and reliability of contact and signal transmission. Furthermore, the electronic device of this invention is easy to use.

[0060] The connector of this invention embodiment, such as Figure 1 and Figure 2 As shown, it includes a resilient contact 2 and an intermediate contact 1. The intermediate contact 1 is adapted to be directly or indirectly soldered to a signal contact 61 on a circuit board 6. The resilient contact 2 has a wiring segment 21 and a resilient contact segment 22. The wiring segment 21 of the resilient contact 2 is adapted to be connected to a cable. The resilient contact segment 22 of the resilient contact 2 is in elastic contact with the intermediate contact 1 to form an electrical connection. The contact portions of the intermediate contact 1 and the resilient contact 2 that are in contact with each other are surface treated to form an anti-oxidation layer.

[0061] The intermediate contact 1 is connected to the signal contact 61 of the circuit board 6 by soldering. The soldered part of the signal contact 61 between the intermediate contact 1 and the circuit board 6 will not be exposed to the air, thus avoiding oxidation of the signal contact 61 between the intermediate contact 1 and the circuit board 6.

[0062] As an example, the intermediate contact 1 and the circuit board 6 are soldered together, and the soldered portion of the signal contact 61 between the intermediate contact 1 and the circuit board 6 is covered by solder to prevent the signal contact 61 between the intermediate contact 1 and the circuit board 6 from being exposed to the air and to prevent oxidation of the signal contact 61 between the intermediate contact 1 and the circuit board 6.

[0063] The elastic contact segment 22 on the elastic contact 2 is in elastic contact with the intermediate contact 1. The part of the intermediate contact 1 and the elastic contact 2 that are in contact with each other will be exposed to air under the action of mechanical force. At least the contact part of the intermediate contact 1 and the elastic contact 2 that are in contact with each other is surface treated to form an anti-oxidation layer to prevent the intermediate contact 1 and the elastic contact 2 from oxidizing.

[0064] Since both intermediate contact 1 and elastic contact 2 are small parts, surface treatment is less difficult and less expensive, resulting in high stability and reliability of contact and signal transmission, enabling the connector to work stably for a long time.

[0065] In addition, the intermediate contact 1 and the elastic contact 2 are in elastic contact, and the intermediate contact 1 is soldered to the circuit board 6, which makes the operation less difficult and the use easier.

[0066] The connector of this invention features an intermediate contact and a resilient contact in elastic contact. The intermediate contact is soldered to the circuit board. During surface treatment, only small components require surface treatment, avoiding the need for surface treatment on the circuit board with numerous contacts. This makes the connector easy to surface treat and reduces surface treatment costs, thereby improving the stability and reliability of the connector's contact and signal transmission. Furthermore, the connector of this invention is relatively easy to use.

[0067] In some embodiments, at least the contact portions of the intermediate contact 1 and the elastic contact 2 that are in contact with each other are plated with gold or immersed in gold to form a gold-plated layer or an immersed in gold layer.

[0068] Gold does not form an oxide film when exposed to air. Plating or immersion gold on at least the contact portions of the intermediate contact 1 and the elastic contact 2 that are in contact with each other can prevent the intermediate contact 1 and the elastic contact 2 from being oxidized. Moreover, the plating and immersion gold layers are relatively firm and will not fall off under mechanical force.

[0069] Therefore, in some embodiments, a gold plating layer or immersion gold layer is formed on the overall outer surface of the intermediate contact 1 by gold plating or immersion gold plating.

[0070] In the gold plating or immersion gold process, it is easier to plate or immerse gold on the entire outer surface of the intermediate contact 1 than to plate or immerse gold on a part of the outer surface of the intermediate contact 1. Plating or immersion gold on the entire outer surface of the intermediate contact 1 can improve the efficiency of gold plating or immersion gold plating of the intermediate contact 1.

[0071] Therefore, in some embodiments, a gold plating layer or immersion gold layer is formed on the entire outer surface of the elastic contact segment 22 of the elastic contact member 2 by gold plating or immersion gold plating.

[0072] In the process of gold plating or immersion gold plating, it is easier to plate or immerse gold plating the entire outer surface of the elastic contact 2 than to plate or immerse gold plating a portion of the outer surface of the elastic contact 2. Plating or immersion gold plating the entire outer surface of the elastic contact 2 can improve the efficiency of gold plating or immersion gold plating of the elastic contact 2.

[0073] In some embodiments, a gold plating layer or immersion gold layer is formed on the overall outer surface of the elastic contact 2 by gold plating or immersion gold plating, which further improves the efficiency of gold plating or immersion gold plating of the elastic contact 2.

[0074] In some embodiments, such as Figure 14 and Figure 15 As shown, the part of the intermediate contact 1 that contacts the elastic contact 2 is a plane.

[0075] When the part of the intermediate contact 1 that contacts the elastic contact 2 is a plane, the contact area between the elastic contact 2 and the intermediate contact 1 is relatively large, and the contact stability is high.

[0076] In some embodiments, the intermediate contact 1 is sheet-like or block-like.

[0077] As an example, such as Figure 7 As shown, the intermediate contact component 1 is block-shaped.

[0078] When the elastic contact 2 is in elastic contact with the block-shaped intermediate contact 1, the gap between the elastic contact 2 and the circuit board 6 is relatively large. That is to say, when the position between the housing 7 and the circuit board 6 reaches the limit position, the compression of the elastic contact 2 in elastic contact with the block-shaped intermediate contact 1 is greater, thereby improving the contact performance of the connector.

[0079] Furthermore, the elastic contact 2, which is in elastic contact with the block-shaped intermediate contact 1, has a greater compression. For connectors with a housing 7, the block-shaped intermediate contact 1 can reduce the size of the elastic contact 2 exposed outside the housing 7. The block-shaped intermediate contact 1 can also reduce the flatness requirement of the elastic contact 2.

[0080] As an example, such as Figure 5 As shown, the intermediate contact element 1 is sheet-shaped.

[0081] When the elastic contact 2 makes elastic contact with the block-shaped intermediate contact 1, the gap between the elastic contact 2 and the circuit board 6 is relatively small. In other words, other parts can be placed between the sheet-shaped intermediate contact 1 and the circuit board 6, increasing the usable space of the electronic device.

[0082] In some embodiments, such as Figure 1 and Figure 2 As shown, the intermediate contact 1 is arc-shaped and protrudes towards the side of the circuit board 6.

[0083] When the intermediate contact 1 comes into contact with the elastic contact 2, the arc shape of the intermediate contact 1 matches the elastic contact segment 22, which makes the contact effect between the intermediate contact 1 and the elastic contact 2 better.

[0084] In addition, the intermediate contact 1 can limit the range of motion of the elastic contact 2, thereby increasing the contact effect between the elastic contact 2 and the intermediate contact 1, and improving the contact performance and electrical performance of the connector.

[0085] As an example, such as Figure 6 and Figure 7 As shown, the intermediate contact 1 is arc-shaped and protrudes towards the side of the circuit board 6, and is block-shaped. The elastic contact 2 has a large compression amount when in contact with the intermediate contact 1, and the elastic contact 2 has a small range of movement relative to the intermediate contact 1, which further improves the contact performance and electrical performance of the connector.

[0086] Furthermore, for connectors with a housing 7, the intermediate contact 1 can further reduce the size of the resilient contact 2 exposed outside the housing 7 and the flatness requirements of the resilient contact 2.

[0087] In some embodiments, such as Figure 13 As shown, the connector also includes an adapter metal 32, the first end 321 of which is adapted to be soldered to the signal contact 61 on the circuit board 6, and the other end 322 of which is soldered to the intermediate contact 1.

[0088] The first end 321 of the adapter metal 32 can be directly soldered to the signal contact 61 on the circuit board 6; the first end 321 of the adapter metal 32 can also be indirectly soldered to the signal contact 61 on the circuit board 6.

[0089] The adapter metal 32 can increase the spacing between the elastic contact 2 and the circuit board 6. That is, when the position between the housing 7 and the circuit board 6 reaches the limit position, the elastic contact 2, which is in elastic contact with the block-shaped intermediate contact 1, has a greater compression, thereby improving the contact performance of the connector.

[0090] The adapter metal 32 can be a single piece or composed of multiple segments.

[0091] As an example, such as Figure 16 As shown, the adapter metal 32 consists of four segments. The other end 322 of the adapter metal 32 is located on the first segment 3211, and the first end 321 of the adapter metal 32 is located on the fourth segment 3214. The first segment 3211, the second segment 3212, the third end 3213 and the fourth segment 3214 are connected end to end by welding from top to bottom.

[0092] In some embodiments, the connector further includes an adapter 3, which has a through hole 31 and an adapter metal 32 therein.

[0093] Optionally, the adapter metal 32 is made of copper.

[0094] Alternatively, the adapter metal 32 can be a copper pillar.

[0095] Specifically, such as Figure 5 As shown, the intermediate contact 1 is plate-shaped. The plate-shaped intermediate contact 1 cooperates with the adapter 3 to increase the compression of the elastic contact 2, thereby improving the contact performance of the connector.

[0096] Furthermore, the intermediate contact 1 is a signal contact 61, and the adapter 3 is a circuit board. The intermediate contact 1 and the adapter 3 cooperate to form an adapter circuit board. In practical applications, it is not necessary to produce the intermediate contact 1 separately, which improves production efficiency and reduces production costs.

[0097] It should be noted that, unlike the circuit board 6 which has more contacts, the adapter circuit board is a small component and has fewer signal contacts 61, making it easier to perform surface treatment.

[0098] Optionally, such as Figure 6 and Figure 7 As shown, the intermediate contact 1 is block-shaped, which can further improve the contact performance and electrical performance of the connector.

[0099] Furthermore, for connectors with a housing 7, the intermediate contact 1 can further reduce the size of the resilient contact 2 exposed outside the housing 7 and the flatness requirements of the resilient contact 2.

[0100] Adapter 3 can be set to one or multiple.

[0101] As an example, such as Figure 5 , Figure 6 and Figure 7 As shown, adapter 3 is provided with one.

[0102] As an example, such as Figure 16 As shown, there are two adapters 3.

[0103] When there are a large number of intermediate contact parts 1, welding each individual intermediate contact part 1 is less efficient.

[0104] Therefore, in some embodiments, such as Figure 4 As shown, there are multiple elastic contact elements 2 and multiple intermediate contact elements 1, and the multiple intermediate contact elements 1 are embedded on the medium plate 4.

[0105] When installing multiple intermediate contacts 1, the dielectric board 4 is soldered as a whole onto the circuit board 6, so that multiple intermediate contacts 1 can be soldered at a time, thereby improving the installation efficiency of the intermediate contacts 1.

[0106] Furthermore, each of the multiple intermediate contacts 1 corresponds to a signal contact 61, and each of the multiple intermediate contacts 1 corresponds to a multiple elastic contact 2.

[0107] In some embodiments, such as Figure 3 As shown, the connector also includes a base 5 suitable for mounting onto the circuit board 6, with the dielectric board 4 fixed on the base 5.

[0108] When installing the medium plate 4, the base 5 can position the medium plate 4, making it easier to weld the medium plate 4 and further improving the installation efficiency of the intermediate contact 1.

[0109] In some embodiments, such as Figure 8 and Figure 9 As shown, the elastic contact segment 22 has a first contact portion 221, a second contact portion 222 for contacting the signal contact 61, and a third contact portion 223. The second contact portion 222 is located between the first contact portion 221 and the third contact portion 223 in the extending direction of the elastic contact segment 22. The elastic contact segment 22 is curved so that the first contact portion 221 and the third contact portion 223 are always in contact or the first contact portion 221 and the third contact portion 223 are spaced apart by a predetermined distance, and the first contact portion 221 and the third contact portion 223 are in contact when the second contact portion 222 contacts the intermediate contact member 1. In other words, when the second contact portion 222 is in contact with the signal contact 61 and not in contact, the contact state of the first contact portion 221 and the third contact portion 223 can be twofold: one is that the first contact portion 221 and the third contact portion 223 always remain in contact regardless of whether the second contact portion 222 is in contact with the signal contact 61 or not; the other is that when the second contact portion 222 is not in contact with the signal contact 61, the first contact portion 221 and the third contact portion 223 also do not contact, and when the second contact portion 222 is in contact with the signal contact 61, the first contact portion 221 and the third contact portion 223 are in contact.

[0110] When the first contact portion 221 contacts the third contact portion 223, such as Figure 9As shown, this can be understood as the elastic contact segment 22 forming a closed state; when the first contact portion 221 and the third contact portion 223 are not in contact, as... Figure 8 As shown, the elastic contact segment 22 can be understood as forming an open shape.

[0111] Since the first contact 221 and the third contact 223 are in contact when the second contact 222 contacts the signal contact 61, the second contact 222 can form a conductive relationship with the wiring segment 21 from two paths at the same time. It can be understood that the elastic contact segment 22 has two cross sections, thereby improving the characteristic impedance of the elastic contact 2.

[0112] For example, such as Figure 8 and Figure 9 As shown, the elastic contact 2 can be roughly divided into two parts: the wiring segment 21 and the elastic contact segment 22. The shapes of the conductors in the cross-sections of the two parts can be different, but both need to meet the characteristic impedance requirement of 85 ohms. The wiring segment 21 is completely encased in plastic in the connector. The elastic contact segment 22 cannot be fixed with plastic when it undergoes bending deformation. The elastic contact segment 22 is mainly surrounded by air, which requires that the area of ​​the signal conductor in the cross-section be larger than that of the wiring segment 21, and the spacing between the signal conductors be smaller than that of the wiring segment 21, in order to achieve the same impedance.

[0113] In some embodiments, the elastic contact 2 is integrally formed from an elastic metal sheet, thereby improving product consistency. At least one of the first contact portion 221, the second contact portion 222, and the third contact portion 223 has a curved contact surface, and the shape of the contact portion of the intermediate contact 1 that contacts the second contact portion 222 is adapted to the shape of the second contact portion 222.

[0114] As an example, when the contact surfaces of the first contact portion 221 and the third contact portion 223 are curved, they can slide relatively smoothly. When the contact surface of the second contact portion 222 is curved, the second contact portion 222 can make better contact with the signal contact 61.

[0115] In some embodiments, such as Figure 10 As shown, the elastic contact section 22 is composed of multiple arc-shaped segments connected together, and the radius of each arc-shaped segment is 0.1mm-6mm. Figure 10 In the design, the elastic contact section 22 consists of four arc-shaped segments with radii R1, R2, R3, and R4, where R1 has the smallest value and R3 has the largest value. The elastic contact section 22 can also include straight segments and arc-shaped segments, meaning that some sections can be designed as straight segments.

[0116] In some embodiments, at least a portion of the elastic contact segment 22 is bent inward or outward.

[0117] Optionally, such as Figure 17 As shown, the entire portion of the elastic contact section 22 is bent inward or outward.

[0118] In some embodiments, the main body shape of the elastic contact segment 22 is any one of a circle, an ellipse, an O-shape, a C-shape, a W-shape, and an S-shape, and the partial shape of the elastic contact segment 22 is one or more of a circle, an ellipse, an O-shape, a C-shape, a W-shape, and an S-shape.

[0119] Optionally, the main body of the elastic contact section 22 is W-shaped, and the local shape of the elastic contact section 22 is S-shaped or W-shaped.

[0120] Optionally, such as Figure 12 As shown, the local shapes of the elastic contact segment 22 are W-shaped and C-shaped.

[0121] Optionally, such as Figure 8 As shown, the main body of the elastic contact section 22 is C-shaped.

[0122] Optionally, such as Figure 10 and Figure 11 As shown, the main body shape of the elastic contact section 22 is elliptical or O-shaped.

[0123] In some embodiments, the second end (i.e. the end point) of the elastic contact segment 22 is bent inward or outward.

[0124] In some embodiments, the elastic contact segment 22 includes an outwardly protruding arc segment 2201 and a zigzag segment 2202 connected to the arc segment 2201, at least a portion of the zigzag segment 2202 being opposite to the arc segment 2201.

[0125] like Figure 10 and Figure 11 As shown, the second end of the elastic contact segment 22 bends inward toward the inner side of the elastic contact segment 22, as... Figure 12 As shown, the second end of the elastic contact segment 22 bends outward from the elastic contact segment 22.

[0126] Specifically, such as Figure 12 As shown, the zigzag segment 2202 has multiple arcs, and the zigzag segment 2202 as a whole can be wavy. The arc segment 2201 has one arc, and the zigzag segment 2202 is located on the concave side of the arc segment 2201.

[0127] Designing the elastic contact section 22 to include an outwardly protruding arc section 2201 and a tortuous section 2202 connected to the arc section 2201 can further improve impedance matching.

[0128] It is understood that the shape of the elastic contact segment 22 can also be other shapes besides those listed in the above embodiments.

[0129] In some embodiments, such as Figure 9 As shown, the elastic contact section 22 is formed by an elastic metal sheet with a rectangular cross-section. The thickness of the elastic metal sheet is 0.06mm-0.12mm, and the width a of the elastic metal sheet is 0.25mm-0.5mm.

[0130] For example, the thickness of the elastic metal sheet is 0.08 mm, and the width of the elastic metal sheet is 0.3 mm. Those skilled in the art can select the thickness and width of the elastic metal sheet according to the performance requirements of different connectors.

[0131] like Figure 10 As shown, the overall height H of the elastic contact section 22 is 2mm-5mm, and the overall width W of the elastic contact section 22 is 1.2mm-2.4mm. Here, the height H refers to the distance from the top to the bottom of the elastic contact section 22, and the overall width refers to the distance from the leftmost to the rightmost end of the elastic contact section 22.

[0132] In some embodiments, the first contact portion 221 is slidable relative to the third contact portion 223.

[0133] When the second contact portion 222 makes elastic contact with the signal contact 61, the signal contact 61 supports the second contact portion 222, causing the elastic contact member 2 to deform elastically. This causes the position of the first contact portion 221 relative to the third contact portion 223 to change. If the first contact portion 221 is always in contact with the third contact portion 223, the first contact portion 221 slides a certain distance relative to the third contact portion 223 when the second contact portion 222 makes elastic contact with the signal contact 61. If the first contact portion 221 is spaced a predetermined distance from the third contact portion 223, the first contact portion 221 gradually moves closer to the third contact portion 223 when the second contact portion 222 makes contact with the signal contact 61, until it makes contact with the third contact portion 223. After making contact, it can slide a certain distance relative to the third contact portion 223.

[0134] In some embodiments, such as Figure 11 As shown, the connector also includes a connecting sleeve 23, which is sleeved on the first contact portion 221 and the third contact portion 223 to constrain the first contact portion 221 and the third contact portion 223, so that the first contact portion 221 and the third contact portion 223 can move relative to each other within a predetermined range, preventing the first contact portion 221 and the third contact portion 223 from separating, and effectively ensuring that the first contact portion 221 can stably contact the third contact portion 223 when the second contact portion 222 contacts the signal contact 61.
