Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a connector, electronic equipment and a signal transmission method. Background Art

[0002] Electronic devices usually include multiple electronic components, including circuit boards and chips, and the circuit boards and chips are connected by signals. There are many ways to achieve the signal connection between the circuit boards and chips, and a more common one includes using a connector to connect the circuit boards and chips.

[0003] With the continuous evolution of electronic devices, the number of transmitted signals is increasing and the speed is getting faster. As an important part of signal transmission, connectors also have an important impact on the operating speed of electronic devices. Therefore, higher requirements are also placed on the speed of connector signal transmission. Summary of the invention

[0004] The present application provides a connector, an electronic device and a signal transmission method. The connector generates less crosstalk, which is beneficial to improving the rate at which the electronic device transmits signals.

[0005] In the first aspect, the present application provides a connector, which includes a housing and a terminal. The housing includes a plurality of mounting grooves, and the terminal is fixedly mounted in the mounting grooves of the housing, so that the terminal and the housing can be fixedly mounted. The terminal includes a first elastic arm, a retaining portion, and a second elastic arm arranged in sequence along a first direction, and the terminal is inserted into the mounting groove, and the retaining portion of the terminal is interference-fitted with the mounting groove. Specifically, at least part of the structure of the first elastic arm can extend out of the mounting groove, and at least part of the structure of the second elastic arm can extend out of the mounting groove, so that the first elastic arm and the second elastic arm are respectively used to connect with electronic components. When the mounting groove is specifically formed, the mounting groove includes a mounting portion and a cutting groove portion that are connected, and the mounting portion and the cutting groove portion are arranged along the first direction. The width of the cutting groove portion along the second direction is greater than the width of the mounting portion along the second direction, and the second direction is the thickness direction of the terminal, and the second direction is perpendicular to the first direction. Specifically, the width of any position of the cutting groove portion along the second direction can be greater than the width of any position of the mounting portion along the second direction. When installing the above-mentioned terminals, multiple terminals can be connected to the same sheet material, so as to facilitate the simultaneous assembly of multiple terminals, and is conducive to simplifying the assembly process of the terminals and improving the assembly efficiency of the terminals. Specifically, the above-mentioned holding portion is also connected to a material belt, which is used to connect with the above-mentioned sheet material. After the installation groove of the above-mentioned shell is assembled, the sheet material is pulled to separate the sheet material from the material belt, so that the end of the material belt away from the holding portion is flush with the bottom of the groove of the cutting portion. Compared with the prior art, the size of the material belt can be greatly reduced, and specifically, the length of the material belt can be reduced by increasing the depth of the cutting portion along the first direction. Since the length of the material belt is reduced, the crosstalk caused by the material belt is also reduced, which is conducive to improving the rate at which the connector transmits signals. In this solution, a shielding sheet may not be provided, and the crosstalk of the terminal can also be reduced, and the signal rate transmitted by the connector can be improved. The structure of the connector is relatively simple and the cost is low.

[0006] When the above-mentioned groove is specifically set, the shape of the groove is not limited. In some optional technical solutions, the width of the groove portion along the second direction gradually increases in the direction away from the mounting portion. The strip and the sheet material are disconnected at the junction of the above-mentioned mounting portion and the groove portion. Therefore, the swing amplitude of the sheet material gradually increases in the direction away from the mounting portion. This solution provides sufficient space for the swing of the sheet material, which is conducive to improving the separation efficiency of the strip and the sheet material. In addition, this solution is also conducive to retaining a larger part of the shell to improve the strength of the shell and improve the structural strength of the entire connector.

[0007] In a possible technical solution, the cutting groove is symmetrical about the terminal. The swing amplitudes of the sheet material on both sides of the second direction Y can be relatively close, which is conducive to simplifying the separation process of the sheet material and the material strip and improving the separation speed of the sheet material and the material strip.

[0008] When the cutting groove is specifically provided, the cutting groove can be a V-shaped groove. In this solution, the structure of the cutting groove is relatively simple, and the processing technology is also relatively simple.

[0009] When the above-mentioned shell is specifically formed, the installation groove of the shell can include a first part, a second part and a third part arranged in sequence along the first direction. The widths of the above-mentioned first part, the second part and the third part along the third direction increase in sequence, and the above-mentioned third direction is perpendicular to the first direction and the second direction. When the terminal is assembled in the above-mentioned installation groove, the retaining portion of the terminal is interference-fitted with the second part of the installation groove. Specifically, when not installed, the width of the above-mentioned retaining portion along the third direction is smaller than the width of the third part along the third direction, so that the retaining portion and the installation groove can be interference-fitted, and the fixing structure is more reliable. The above-mentioned cutting groove portion is located in the third part, and the terminal is inserted into the above-mentioned installation groove from the third part. The insertion process is relatively smooth, and a shoulder is formed between the second part and the first part, which abuts against the retaining portion to limit the above-mentioned terminal in the first direction.

[0010] The holding portion further includes a hollow structure to enhance the elasticity of the holding portion and facilitate the holding portion to extend into the second portion of the mounting slot. In a specific embodiment, the hollow structure may be a circular hole or an elliptical hole.

[0011] When the holding portion is specifically arranged, the holding portion is symmetrically arranged about the symmetry axis in the third direction, and specifically, the symmetry axis extends along the first direction. The hollow structure is also symmetrically arranged about the symmetry axis in the third direction, and the third direction is perpendicular to the first direction and the second direction. In this solution, the holding portion and the hollow structure are both symmetrical structures, so the forces between the two are relatively balanced.

[0012] The material belt is used to connect with the plate material. In order to facilitate the separation of the material belt and the plate material, a weak point is provided between the material belt and the plate material. Then, when the plate material is shaken, it can be quickly separated from the material belt.

[0013] In the second aspect, the present application also provides a housing. The housing is a housing of a connector, and the housing includes a plurality of mounting grooves, which are used to install terminals. When the mounting groove is specifically formed, the mounting groove includes a mounting portion and a cutting groove portion that are connected, and the mounting portion and the cutting groove portion are arranged along a first direction. The width of the cutting groove portion along the second direction is greater than the width of the mounting portion along the second direction, and the second direction is the thickness direction of the terminal, and the second direction is perpendicular to the first direction. Specifically, the width of any position of the cutting groove portion along the second direction can be greater than the width of any position of the mounting portion along the second direction. When installing the above-mentioned terminal, multiple terminals can be connected to the same sheet material, so as to facilitate the simultaneous assembly of multiple terminals, and is conducive to simplifying the assembly process of the terminal and improving the assembly efficiency of the terminal. Specifically, the above-mentioned holding portion is also connected to a material belt, which is used to connect to the above-mentioned sheet material. After the mounting groove of the above-mentioned housing is assembled, the sheet material is pulled to separate the sheet material from the material belt, so that the end of the material belt away from the holding portion is flush with the bottom of the groove of the cutting groove portion. Compared with the prior art, the size of the material strip can be greatly reduced. Specifically, the length of the material strip can be reduced by increasing the depth of the cutout portion along the first direction. Since the length of the material strip is reduced, the crosstalk caused by the material strip is also reduced, which is beneficial to improving the rate at which the connector transmits signals. In this solution, a shielding sheet may not be provided, and the crosstalk of the terminal can also be reduced, thereby improving the signal rate transmitted by the connector. The structure of the connector is relatively simple and the cost is relatively low.

[0014] When the above-mentioned groove is specifically set, the shape of the groove is not limited. In some optional technical solutions, the width of the groove portion along the second direction gradually increases in the direction away from the mounting portion. The strip and the sheet material are disconnected at the junction of the above-mentioned mounting portion and the groove portion. Therefore, the swing amplitude of the sheet material gradually increases in the direction away from the mounting portion. This solution provides sufficient space for the swing of the sheet material, which is conducive to improving the separation efficiency of the strip and the sheet material. In addition, this solution is also conducive to retaining a larger part of the shell to improve the strength of the shell and improve the structural strength of the entire connector.

[0015] In a possible technical solution, the cutting groove is symmetrical about the terminal. The swing amplitudes of the sheet material on both sides of the second direction Y can be relatively close, which is conducive to simplifying the separation process of the sheet material and the material strip and improving the separation speed of the sheet material and the material strip.

[0016] When the cutting groove is specifically provided, the cutting groove can be a V-shaped groove. In this solution, the structure of the cutting groove is relatively simple, and the processing technology is also relatively simple.

[0017] When the above-mentioned shell is specifically formed, the installation groove of the shell can include a first part, a second part and a third part arranged in sequence along the first direction. The widths of the above-mentioned first part, the second part and the third part along the third direction increase in sequence, and the above-mentioned third direction is perpendicular to the first direction and the second direction. When the terminal is assembled in the above-mentioned installation groove, the retaining portion of the terminal is interference-fitted with the second part of the installation groove. Specifically, when not installed, the width of the above-mentioned retaining portion along the third direction is smaller than the width of the third part along the third direction, so that the retaining portion and the installation groove can be interference-fitted, and the fixing structure is more reliable. The above-mentioned cutting groove portion is located in the third part, and the terminal is inserted into the above-mentioned installation groove from the third part. The insertion process is relatively smooth, and a shoulder is formed between the second part and the first part, which abuts against the retaining portion to limit the above-mentioned terminal in the first direction.

[0018] In a third aspect, the present application also provides a terminal, which is a terminal of a connector. The terminal includes a first elastic arm, a retaining portion, and a second elastic arm arranged in sequence along a first direction, the terminal is inserted into a mounting groove, and the retaining portion of the terminal is interference fitted with the mounting groove. Specifically, at least part of the structure of the first elastic arm can extend out of the above-mentioned mounting groove, and at least part of the structure of the second elastic arm can extend out of the above-mentioned mounting groove, so that the first elastic arm and the second elastic arm are respectively used to connect with electronic components. The above-mentioned retaining portion also includes a hollow structure. In order to enhance the elasticity of the retaining portion, it is convenient for the retaining portion to extend into the second part of the mounting groove. In a specific embodiment, the above-mentioned hollow structure can be a structure such as a round hole or an elliptical hole.

[0019] In a fourth aspect, the present application also provides an electronic component. The electronic device includes a circuit board, a chip, and the connector provided in the first aspect. The connector is arranged between the circuit board and the chip, and the circuit board and the chip are respectively connected to the terminals of the connector. Specifically, the first elastic arm of the terminal can be connected to the chip, and the second elastic arm of the terminal can be connected to the circuit board. In this solution, the material strip of the terminal is shorter, and the crosstalk generated is less, which is conducive to improving the signal rate transmitted by the electronic component.

[0020] In a fifth aspect, the present application further provides an electronic device. The electronic device comprises a housing and the electronic component of the fourth aspect, wherein the electronic component is disposed in the housing. In this solution, the material strip of the terminal of the connector is shorter, and less crosstalk is generated, which is conducive to improving the signal rate transmitted by the electronic device.

[0021] In a sixth aspect, the present application also provides a signal transmission method, which specifically uses the connector provided in the first aspect to transmit signals. The terminals of the connector may specifically include a power terminal and a communication terminal, and the signal transmission method specifically includes: transmitting a power signal through the power terminal, and transmitting a communication signal through the communication terminal. In this solution, the crosstalk of the terminals is small, and the rate of the signal that can be transmitted is high, which is conducive to improving the communication efficiency of the user.

[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0045] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application. As used in the specification and appended claims of the present application, the singular expressions "a", "an", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0046] References to "one embodiment" or "a specific embodiment" described in this specification mean that one or more embodiments of the present application include a particular feature, structure or characteristic described in conjunction with the embodiment. The terms "include", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0047] To facilitate understanding of the connector, housing, terminal, electronic component, and electronic device provided in the embodiments of the present application, the application scenarios thereof are first introduced below.

[0048] The electronic device in the embodiment of the present application can be a communication device (such as a router), a computing device (such as a server), a network device (such as a switch) or a storage device (such as a storage array) and other electronic devices, especially electronic devices with high-speed signal transmission requirements. The present application does not limit the specific type of electronic device, as long as the electronic device uses a connector to connect the chip to the circuit board, the technical solution provided by the present application can be adopted.

[0049] For ease of description, the embodiments of the present application are described by taking the electronic device as a server as an example. Figure 1 is a schematic diagram of the structure of an electronic device in an embodiment of the present application, such as Figure 1 As shown, the electronic device may include a housing 100 and an electronic component 200 disposed in the housing 100. Specifically, when the electronic device is a cabinet server, the housing 100 may be understood as a cabinet of the cabinet server, and the electronic component 200 may include a node. Figure 1As shown, the electronic component 200 specifically includes a circuit board 1 and a chip 2, and the plurality of chips 2 are arranged on the circuit board 1 to form the electronic component 200. As the rate of signals transmitted in electronic devices becomes higher and higher, the rate of signals transmitted between the chip 2 and the circuit board 1 also gradually increases. For example, the chip 2 arranged on the circuit board 1 may be an artificial intelligence (AI) chip or a graphics processing unit (GPU), which is used to perform computationally intensive or memory-intensive business data processing such as artificial intelligence or high-performance computing (HPC).

[0050] Figure 2 is a schematic diagram of the structure of an electronic component in an embodiment of the present application, such as Figure 2 As shown, in a specific embodiment, the electronic component 200 includes a circuit board 1, a chip 2 and a connector 3, and the connector 3 is connected between the circuit board 1 and the chip 2 to achieve signal transmission between the chip 2 and the circuit board 1. Specifically, the connector 3 includes a housing 31 and a terminal 32, and the terminal 32 is fixed to the housing 31, and the two ends of the terminal 32 are respectively connected to the chip 2 and the circuit board 1. Figure 2 In the illustrated embodiment, the electronic component 200 may further include a heat sink 4, which is mounted on the side of the chip 2 facing away from the circuit board 1. In order to assemble the heat sink 4, the circuit board 1 is further connected with a bracket 5, which may be fixedly connected to the circuit board 1 by screws or pins. The heat sink 4 is threadedly connected to the bracket 5 by screws, and may be elastically connected, that is, an elastic member such as a spring is disposed on the outer sleeve of the screw. The pressure applied by the heat sink 4 causes the chip 2, the connector 3 and the circuit board 1 to be crimped, thereby realizing the connection between the chip 2 and the terminal 32, and the connection between the circuit board 1 and the terminal 32, thereby realizing the connection between the chip 2 and the circuit board 1. Alternatively, in another embodiment, the connector 3 may also be used to realize the connection between circuit boards, which is not limited in the present application.

[0051] Figure 3 This is a schematic diagram of the structure of the connector 3 in the embodiment of the present application. Figure 4 FIG. 1 is a schematic diagram of a partial structure of the connector 3 in the embodiment of the present application. Figure 3 and Figure 4 As shown, the connector 3 in the embodiment of the present application includes a housing 31 and a terminal 32, and the housing 31 can be specifically a housing 31 made of plastic. The housing 31 includes a plurality of mounting grooves 311, and the terminal 32 is interference-fitted in the mounting grooves 311. In a specific embodiment, the terminal 32 and the mounting groove 311 are installed one-to-one. Figure 5 This is a partial cross-sectional structural diagram of the housing 31 in the embodiment of the present application. Figure 6 FIG. 2 is a schematic diagram of a partial cross-sectional structure of the connector 3 in the embodiment of the present application. The cross section is parallel to the largest surface of the terminal 32. Figure 5 and Figure 6 As shown, the terminal 32 includes a first elastic arm 321, a holding portion 322, and a second elastic arm 323 arranged in sequence along the first direction X, and the holding portion 322 is fitted with the mounting groove 311 by interference fit to achieve a fixed connection between the terminal 32 and the housing 31. The first elastic arm 321 and the second elastic arm 323 can specifically extend out of the mounting groove 311. The first elastic arm 321 and the second elastic arm 323 are respectively used to be electrically connected to the chip 2 and the circuit board 1. In a specific embodiment, the housing 31 may also have a receiving space, which is communicated with the mounting groove 311 and is used to receive the first elastic arm 321 and the second elastic arm 323, and in particular, when the first elastic arm 321 and the second elastic arm 323 are deformed by force, they are deformed toward the receiving space. Specifically, the chip 2 may include a first pin, which is crimped with the first elastic arm 321; the circuit board 1 includes a second pin, which is crimped with the second elastic arm 323, and the first pin and the second pin can be connected through the terminal 32 to transmit signals.

[0052] Figure 7 FIG. 2 is another partial cross-sectional structural diagram of the connector 3 in the embodiment of the present application, wherein the cross section is perpendicular to the largest surface of the terminal 32. Figure 7As shown, the mounting groove 311 includes a mounting portion 3111 and a notch portion 3112, and the mounting portion 3111 and the notch portion 3112 are connected to each other. In order to install the terminal 32, the width of the mounting portion 3111 along the second direction Y is relatively small, and the second direction Y can be understood as the thickness direction of the terminal 32, which is specifically perpendicular to the first direction X. The width of the notch portion 3112 in the second direction Y is greater than the width of the mounting portion 3111 in the second direction Y. The notch portion 3112 can be understood as the mounting groove 311 having an expansive opening at the end. In a specific embodiment, the width of the notch portion 3112 at any position in the second direction Y can be greater than the width of the mounting portion 3111 at any position in the second direction Y. When the connector 3 is prepared, a plurality of terminals 32 are connected into a strip shape through a sheet material 6. Specifically, the retaining portion 322 is connected with a material strip 324, and the material strip 324 is connected to the sheet material 6, so that each terminal 32 is connected to the sheet material 6. During assembly, the sheet material 6 drives the terminal 32 to be inserted into the mounting groove 311 of the housing 31. After being inserted into place, the retaining portion 322 of the terminal 32 is fitted with the mounting groove 311 by interference fit, and the sheet material 6 is pulled to shake in the cutting groove portion 3112 along the second direction Y, so that the sheet material 6 is separated from the material strip 324. Since the width of the mounting portion in the second direction Y is smaller than the width of the cutting groove portion 3112 in the second direction Y, when the sheet material 6 shakes in the cutting groove portion 3112, the area between the sheet material 6 and the material strip 324 is repeatedly bent along the end of the mounting portion (that is, the bottom of the cutting groove portion 3112) until it is broken, so that the end of the material strip 324 away from the retaining portion 322 is flush with the bottom of the cutting groove portion 3112. Compared with the prior art, the size of the material strip 324 can be greatly reduced, and specifically, the length of the material strip 324 can be reduced by increasing the depth of the cutting groove portion 3112 along the first direction X. Since the length of the material strip 324 is reduced, the crosstalk caused by the material strip 324 is also reduced. In a specific embodiment, the resonant frequency generated by the material strip 324 can be made higher than the frequency of the signal transmitted by the connector 3, which is beneficial to improving the rate of signal transmission of the connector 3. In this solution, the shielding sheet may not be provided, and the crosstalk of the terminal 32 can also be reduced, and the signal rate of the connector 3 can be improved. The structure of the connector 3 is relatively simple and the cost is low.

[0053] In order to facilitate the separation of the sheet material 6 from the material strip 324, a weak point 61 may be provided between the sheet material 6 and the material strip 324. In order to form the weak point 61, a groove, pre-bend or thinning may be formed between the sheet material 6 and the material strip 324, so that when the sheet material 6 is shaken, the sheet material 6 may be separated from the material strip more quickly, thereby improving the preparation efficiency of the connector 3.

[0054] Please continue to refer to Figure 7When the above-mentioned cutting groove portion 3112 is specifically set, the cutting groove portion 3112 can be set symmetrically about the terminal 32. Then, when the above-mentioned sheet material 6 is shaken in the cutting groove portion 3112, the shaking amplitude of the sheet material 6 on both sides of the second direction Y can be relatively close, which is beneficial to simplify the separation process of the sheet material 6 and the material strip 324 and improve the separation speed of the sheet material 6 and the material strip 324.

[0055] In a specific embodiment, the shape of the surface of the above-mentioned groove portion 3112 is not limited, for example, it can be a convex surface, a concave surface or a plane, etc., and can be specifically designed according to needs. In addition, for the groove portion 3112 itself, the width of the groove portion 3112 in the second direction Y gradually increases along the direction away from the material belt 324. Since the farther the sheet material 6 is from the material belt 324, the greater the amplitude of the shaking, this solution can make the sheet material 6 have a larger shaking space, which is also beneficial to improve the separation speed of the sheet material 6 and the material belt 324. And only in the position where the sheet material 6 shakes a lot, it is beneficial to retain more parts of the shell 31 to improve the strength of the shell 31 and improve the structural strength of the entire connector 3.

[0056] Specifically, this application Figure 7 In the embodiment shown, the surface of the cutting groove portion 3112 is a plane and is formed into a V-shaped groove. The V-shaped groove is conducive to adapting to the shaking of the sheet material 6, and has a relatively simple structure and a relatively simple processing technology.

[0057] Please refer to Figure 5 and Figure 6In a specific embodiment, the mounting groove 311 of the housing 31 includes a first portion 3113, a second portion 3114 and a third portion 3115 arranged in sequence along the first direction X, and the widths of the first portion 3113, the second portion 3114 and the third portion 3115 along the third direction Z increase in sequence, that is, the width of the third portion 3115 along the third direction Z is greater than the width of the second portion 3114 along the third direction Z, and the width of the second portion 3114 along the third direction Z is greater than the width of the first portion 3113 along the third direction Z. The third direction Z is perpendicular to the first direction X and the second direction Y. Specifically, the first direction X can be understood as the length direction of the terminal 32, the second direction Y can be understood as the thickness direction of the terminal 32, and the third direction Z can be understood as the width direction of the terminal 32. The cutout portion 3112 is located in the third portion 3115 of the mounting groove 311. When the terminal 32 is installed, the terminal 32 can be inserted into the mounting groove 311 from the third portion 3115. The width of the terminal 32 along the third direction Z at the retaining portion 322 is greater than the width of the first elastic arm 321 along the third direction Z, and greater than the width of the second elastic arm 323 along the third direction Z. Since the width of the third portion 3115 is relatively wide, the width of the third portion 3115 of the mounting groove 311 along the third direction Z is greater than the width of the retaining portion 322 along the third direction Z, so that the terminal 32 can be inserted into the third portion 3115 of the mounting groove 311 more conveniently and smoothly; the width of the second portion 3114 of the mounting groove 311 along the third direction Z is less than the width of the retaining portion 322 along the third direction Z, so that the retaining portion 322 and the second portion 3114 are interference-fitted in the third direction Z, so that the terminal 32 is fixed to the housing 31. In this solution, the setting of the third part 3115 of the installation groove 311 reduces the difficulty of inserting the terminal 32 into the installation groove 311, and a shoulder 3116 is formed between the first part 3113 and the second part 3114. The shoulder 3116 can abut against the retaining portion 322, so that the terminal 32 is fixed at a preset position along the first direction X.

[0058] In addition, the above-mentioned retaining portion 322 includes a hollow structure 3221. The setting of the hollow structure 3221 reduces the rigidity of the retaining portion 322, and the retaining portion 322 has a certain elasticity, which makes it easy to insert the retaining portion 322 into the second part 3114 of the installation groove 311, and the terminal 32 is not easy to bend, thereby improving the assembly yield of the connector 3.

[0059] The present application does not limit the shape and number of the hollow structures 3221. In a specific embodiment, the retaining portion 322 is symmetrically arranged about the symmetry axis 7 in the third direction Z, and the symmetry axis 7 extends along the first direction X. The hollow structures 3221 are also symmetrically arranged about the symmetry axis 7 in the third direction Z. This embodiment makes the retaining portion 322 a symmetrical structure as a whole, and the retaining portion 322 is interference-fitted with the mounting groove 311 on both sides of the third direction Z, so the retaining portion 322 is subjected to force on both sides of the third direction Z. The retaining portion 322 is a symmetrical structure as a whole, so the force is relatively uniform and it is not easy to bend.

[0060] like Figure 6 In the illustrated embodiment, the hollow structure 3221 is two elliptical holes, which are identical and symmetrically arranged about the symmetry axis 7 .

[0061] The present application also provides a signal transmission method, which specifically utilizes the connector provided by the present application to transmit signals. The terminals of the above-mentioned connector may specifically include power terminals and communication terminals, and the above-mentioned signal transmission method specifically includes: transmitting power signals through the power terminals, and transmitting communication signals through the communication terminals.
