Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency connectors, and particularly relates to a high-frequency connector with a crosstalk elimination function. Background Art

[0002] High-frequency connectors are used in many electronic systems to transmit data between high-frequency connectors and other electronic components, and the data transmission speed is also getting higher and higher.

[0003] For example, the electrical connector, its sub-assembly and electronic system with the application number 202322372777.8 disclose that the conductor row includes at least a pair of first-type conductors for transmitting differential signals. The middle part of each first-type conductor (for signal transmission) includes a first section and a second section which are spaced apart in their respective length directions. The first section and the second section are connected by an AC capacitor embedded in the sub-assembly housing. The unique design of this electrical connector and its sub-assembly can reduce resonance or current crosstalk in the circuit, reduce insertion loss at the same time, and improve signal integrity. It solves the crosstalk problem in the process of high-speed signal transmission, but it makes the structure of each first-type conductor more complex. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-frequency connector with a crosstalk elimination function. The filtering effect can be achieved by connecting the conductor sheet with the first signal terminal, and the series connection effect is realized by the conductor connection belt, so as to solve the problem of high-speed crosstalk, ensure the clarity and stability of signal transmission, and the connecting piece is not connected to the second signal terminal with the function of transmitting high-speed signals, which can ensure that the second signal terminals do not interfere with each other and ensure the stability of their respective functions.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a high-frequency connector with a crosstalk elimination function, including a housing, a power conductor and a signal conductor arranged on the housing.

The contact sheet is disposed on the first signal terminal, and a support sheet is provided on the contact sheet for connecting the conductor connection strip and lifting the conductor connection strip to form a gap between the conductor connection strip and the second signal terminal.

[0023] The following are specific embodiments of the present utility model in combination with the accompanying drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0024] As Figures 1 to 4 shown, a high-frequency connector with crosstalk elimination function includes a housing, and signal conductors 1 and power conductors 2 provided on the housing. The signal conductors 1 include a pair of terminal strips 10 oppositely arranged on the housing. The terminal strip 10 includes a signal terminal row 11 and a connecting member 12. The connecting member 12 can be made of copper, and includes a conductor connecting strip 121 and a plurality of conductor sheets 122 provided on the conductor connecting strip 121. The plurality of conductor sheets 122 are respectively connected to the first signal terminals 111 with bending structures in the signal terminal row 11, for example, the two are connected by welding. There is a gap between the connecting member 12 and the second signal terminals 112 with straight structures in the signal terminal row 11 and they do not contact each other.

[0025] In the present utility model, two signal terminal rows 11 arranged vertically opposite to each other in the signal conductor 1 are used for signal transmission. Among them, the second signal terminal 112 can be configured to transmit high-speed signals, and the first signal terminal 111 can be configured to provide a reference or return path for the signal. The first signal terminal 111 has a bent structure, and its structure and transmission characteristics require it to have a certain filtering effect. Therefore, a copper conductor sheet 122 is welded onto the first signal terminal 111 to achieve the filtering effect. However, independently connecting the conductor sheets 122 to each first signal terminal 111 may result in different filtering effects for each first signal terminal 111, with some being strong and some being weak. Therefore, connecting multiple conductor sheets 122 in series through a conductor connecting strip 121 can achieve consistency in the filtering effect, solve the problem of high-speed crosstalk, and ensure clear and stable signal transmission. Moreover, the gap formed between the connecting member 12 that serially connects multiple first signal terminals 111 and the second signal terminal 112 is not eliminated, which can ensure that the second signal terminals 112 do not connect in series with each other or with the first signal terminal 111, and the second signal terminals 112 do not interfere with each other, ensuring the stability of their respective functions.

[0026] More specifically, the conductor sheet 122 includes a support sheet 1221 and a contact sheet 1222. The contact sheet 1222 is disposed (welded) on the first signal terminal 111, and the support sheet 1221 is provided on the contact sheet 1222 for connecting the conductor connecting strip 121 and lifting the conductor connecting strip 121 to form a gap with the second signal terminal 112.

[0027] Preferably, the contact sheet 1222 has a square structure, which can have a certain area for stable welding, and its width is less than or equal to the width of the first signal terminal at its connection part, avoiding accidentally touching the second signal terminal due to its large width.

[0028] Combined Figure 5 As shown, for the specific structure of the housing, it includes an outer shell 40 and an inner shell. The inner shell includes a first injection molded part 31 and a second injection molded part 32. The middle positions of the two terminal strips 10 are respectively formed in the first injection molded part 31 and the second injection molded part 32. For example, through injection molding, the injection molding material wraps the middle part of the terminal strip 10, and the injection molding material also fills the gap between the second signal terminal 112 and the connecting member 12, which not only ensures the connection stability between the connecting member 12 and the signal terminal row 11, but also ensures that the connecting member 12 only serially connects multiple first signal terminals 111 and does not connect to the second signal terminal 112. Similarly, a pair of power terminal rows 20 that make up the power conductor 2 are also processed and formed on the first injection molded part 31 and the second injection molded part 32 simultaneously with the terminal strip 10.

[0029] On the side wall of the first injection molded part 31 close to the second injection molded part 32, there is a T-shaped slot 311. On the side wall of the second injection molded part 32 close to the first injection molded part 31, there is a T-shaped block 321. By embedding the block 321 into the slot 311, the stability and accuracy of the connection between the second injection molded part 32 and the first injection molded part 31 can be achieved, so as to ensure the accurate position of a pair of signal terminal rows 11 located on both of them. Then, the connected first injection molded part 31 and second injection molded part 32 are installed in the slot 401 of the housing 40 to form the entire connector main body structure.

[0030] Furthermore, on the side walls of the first injection molded part 31 and the second injection molded part 32 away from each other, there are respectively provided with a plurality of bumps 30. The bumps 30 have guiding inclined surfaces. On the housing 40, there is an embedding groove 402 that is vertically communicated with the slot 401 and matches the bumps 30. The bumps 30 can smoothly move in the slot 401 through the guiding inclined surfaces they have and be clamped in the embedding groove 402 to fix the first injection molded part 31 and the second injection molded part 32 on the housing 40, realizing the stable installation of the overall structure.

[0031] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
