Description

Technical Field

[0001] This application relates to the field of connectors, and particularly to a high-speed female connector. Background Art

[0002] High-speed connectors with transmission rates of 32GT / s and 64GT / s, supporting SATA, SAS, and PCIe protocols, are mainly applied to servers, data centers, and storage.

[0003] During the process of the PCB board on the online end being plugged into the MCIO high-speed connector, if the operation is improper or the design is unreasonable, it is very easy to occur the reverse plugging phenomenon. Reverse plugging means that the plugging direction of the connector and the PCB board is incorrect, resulting in the connector being unable to be correctly inserted or having poor contact after insertion. This phenomenon will not only affect the efficiency and stability of data transmission, but may also cause damage to the MCIO connector itself, such as problems like terminal feeding PIN.

[0004] Among them, the physical structure is damaged: during reverse plugging, the pins of the connector may be abnormally squeezed or bent, resulting in damage to the physical structure.

[0005] In addition, the circuit connection is abnormal: the pins cannot be correctly aligned with the pads on the PCB board, resulting in abnormal circuit connection, and thus affecting data transmission.

[0006] Moreover, terminal feeding PIN means that the pins of the connector are subjected to excessive force or improper operation during insertion or extraction, resulting in the pins coming out of or deforming from the connector body. This phenomenon will seriously affect the service life and performance of the connector. Summary of the Utility Model

[0010] In one embodiment, the limiting convex part is recessed downward from the lower inner wall of the housing.

[0011] In one embodiment, there are 2 limiting convex parts.

[0012] In one embodiment, a bending limiting part is respectively formed inward on the left inner wall and the right inner wall of the housing, and the bending limiting part abuts against the insulating seat body.

[0013] In one embodiment, limiting grooves are respectively provided on the upper surface of the insulating base near the left and right sides, and the bent limiting portion abuts in the limiting grooves to limit the movement of the insulating base.

[0025] The terms used in the embodiments part of the present application are only used to explain the specific embodiments of the present application, rather than aiming to limit the present application. The following will describe the embodiments of the present application in detail with reference to the drawings.

[0026] Embodiment 1

[0027] As shown Figure 1 in the figure, a high-speed female terminal connector includes a housing, an insulating seat body, and terminals. The insulating seat body is disposed within the housing, and the terminals are disposed within the insulating seat body. A limiting convex portion is formed outwardly on one side wall of the housing for restricting the insertion of a reversely inserted male terminal connector into the slot of the insulating seat body. The object of this embodiment is made of metal, and the limiting convex portion is formed by stamping. As shown Figure 2 in the figure, when the reversely inserted male terminal connector is inserted into the slot of the insulating seat body, the male terminal connector will be blocked by the limiting convex portion, making it impossible to insert into the slot of the female terminal connector, thereby playing a role in protecting the connector.

[0028] As shown Figure 1 in the figure, in one of the embodiments, the housing has an upper inner wall, a lower inner wall, a left inner wall, and a right inner wall, and the limiting convex portion is recessed downward from the lower inner wall of the housing. This design not only realizes the limiting function to prevent reverse insertion, but also optimizes the overall structure of the housing by the downward recessed manner, which may help reduce material usage, lower manufacturing costs, while maintaining the compactness and aesthetics of the housing.

[0029] As shown Figure 1 in the figure, in one of the embodiments, there are 2 limiting convex portions provided. Increasing the number of limiting convex portions can further enhance the effect of preventing reverse insertion, and improve the accuracy and stability of connection. The two limiting convex portions can provide a more balanced limiting force, reducing the stress concentration problem that may be caused by a single limiting point.

[0030] As shown Figure 3 in the figure, in one of the embodiments, a bending limiting portion is respectively formed inwardly on the left inner wall and the right inner wall of the housing, and the bending limiting portion abuts against the insulating seat body. This design effectively restricts the forward and backward or up and down movement of the insulating seat body within the housing through the direct contact between the bending limiting portion and the insulating seat body, enhancing the overall structural stability of the connector. At the same time, this mechanical limiting method also simplifies the assembly process and can achieve a stable connection without additional fasteners.

[0031] As shown Figure 3 in the figure, in one of the embodiments, limiting grooves are respectively provided near the left and right sides of the upper surface of the insulating seat body, and the bending limiting portion abuts in the limiting grooves for restricting the movement of the insulating seat body. When the male terminal connector is pulled out from the insulating seat body of the female terminal connector, the bending limiting portion cooperates with the side walls of the limiting grooves to restrict the forward movement of the insulating seat body. The cooperative design of the limiting grooves and the bending limiting portion further improves the positioning accuracy and stability of the insulating seat body within the housing. This precise limiting mechanism helps reduce electrical connection problems caused by the movement of the insulating seat body, and improves the reliability and stability of data transmission.

[0032] As Figure 3 shown, in one embodiment, limiting grooves are respectively provided near the left and right sides of the upper surface of the insulating base body. Reinforcing ribs are provided on the surface of the limiting grooves, and the bent limiting portion abuts against the reinforcing ribs to limit the movement of the insulating base body. The reinforcing ribs extend from the rear to the front, and the cross-section of the reinforcing ribs is arc-shaped or other shapes. When the bent limiting portion is bent inward from the housing, some problems will indeed be encountered if no raised reinforcing ribs are provided.

[0033] First of all, without the reinforcing ribs, the bent limiting portion may first be pressed against the side portion of the insulating base body during the bending process. In this case, the bent limiting portion may not be able to fully play its role in restricting the up-and-down movement of the insulating base body. Because the contact on the side mainly restricts the left-right or front-back movement, and the limiting effect on the up-and-down direction is weak.

[0034] Secondly, the raised design of the reinforcing ribs not only increases the contact area between the bent limiting portion and the insulating base body, but also changes the position of the contact point. By making the reinforcing ribs raised, the bent limiting portion can directly abut against the upper surface or near the lower surface of the insulating base body, thereby more effectively restricting its up-and-down movement. This design ensures that the bent limiting portion can be correctly positioned and pressed at the desired position after bending.

[0035] In addition, the raised reinforcing ribs also provide additional structural strength and stiffness, which helps to prevent the bent limiting portion from deforming or being damaged when subjected to external forces. This is crucial for maintaining the stability and reliability of the connector.
