Description

Technical Field

[0001] This utility model relates to the field of electronic connector technology, and more specifically, to an electronic connector. Background Technology

[0002] Electronic connectors are indispensable key components in modern electronic devices, used to establish separable electrical connections between circuits, components, or systems. As electronic products develop towards higher density, miniaturization, and higher reliability, the performance requirements for connectors are also increasing.

[0003] In many applications, such as automotive electronics, industrial automation equipment, and large server racks, equipment is subjected to continuous vibration or shock during operation. Furthermore, when two connectors (e.g., board-to-board connectors) are mated and installed, it is difficult to achieve perfectly precise alignment between them due to tolerances accumulated during manufacturing and assembly.

[0004] Traditional rigid connectors cannot effectively buffer vibration or tolerance issues due to their rigid structure. Vibration can cause fretting wear between terminals, or even momentary disconnection, affecting signal integrity. Assembly tolerances can prevent connectors from mating properly, or generate huge internal stress after forced mating, damaging the terminals and plastic housing, and reducing connection reliability over long-term use.

[0005] To address this issue, the industry has developed what's known as "floating connectors." Existing floating connectors typically achieve their floating function by adding independent elastic elements (such as metal springs or helical springs) to the structure. However, this design adds extra parts, making the connector structure more complex and increasing assembly costs and difficulty. Furthermore, the additional elastic elements occupy valuable internal space, which contradicts the trend towards miniaturization and high density in connectors.

[0006] Therefore, how to design an electronic connector that is simple in structure, saves space, and can effectively realize floating function has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0007] In view of the above situation, it is necessary to provide an electronic connector that solves at least one of the above problems, comprising: The housing (10) has an adapter groove (11) on it. A connector (20) is accommodated in the adapter groove (11) and is configured to be movable relative to the housing (10); the connector (20) is provided with at least one fixing hole (21), at least one strip-shaped groove (22) and at least one through groove (23).

The bent portion (31) of the bent terminal (30) elastically supports the connector (20) to achieve its movable connection relative to the housing (10).

[0008] Preferably, the housing (10) has fixed slots (12) arranged on the inner walls of the two transverse sides of the adapter groove (11), and slots (13) are provided at the bottom of the two longitudinal sides of the adapter groove (11).

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The technical solutions of this solution will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this solution, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this solution without creative effort are within the scope of protection of this solution.

[0020] Please see Figures 1 to 5 This solution provides an electronic connector, which is mainly composed of a housing (10), a connector (20) and multiple bent terminals (30).

[0021] like Figures 1 to 5 As shown, the housing (10) is the outer frame of the connector, which is usually injection molded from insulating plastic material. An adapter groove (11) is provided at the center of the interior of the housing (10), which provides space for subsequent accommodating of the connector (20).

[0022] The connector (20) is also an insulating plastic part, and its overall shape matches the adapter groove (11) of the housing (10), so it can be accommodated within the adapter groove (11). One of the core aspects of this solution is that the connector (20) is not rigidly fixed in the adapter groove (11), but is constructed to be movable relative to the housing (10). This mobility is the "floating" function that this solution aims to achieve.

[0023] To achieve this function, a specific mounting structure is provided on each bent terminal (30) on the connector (20), including a fixing hole (21) at the top, a strip-shaped slot (22) on the side, and a through slot (23) at the bottom.

[0024] The bent terminal (30) is stamped from a conductive metal material and bent into a specific shape. At least one section is designed as a flexible bend (31).

[0025] During assembly, each bent terminal (30) is mounted on the connector (20) along a specific path. Specifically, one end of the bent terminal (30) (e.g., its fixed end or solder end) is pressed or snapped into the fixing hole (21) of the connector (20) for secure fixation. The other end of the bent terminal (30) (e.g., its contact end) is led out from the fixing hole (21), passes through the strip-shaped slot (22) on the side wall, extends downward through the through slot (23) at the bottom, and finally protrudes from the bottom of the connector (20) for contact with the mating connector.

[0026] Through the above assembly method, the bent portions (31) of the bent terminals (30) are cleverly positioned between the fixing hole (21), the strip-shaped slot (22), and the through slot (23). When the connector (20) together with all the bent terminals (30) fixed thereon are placed into the adapter slot (11) of the housing (10), the elastic bent portions (31) of these bent terminals (30) act as a spring-like support. When an external force (such as vibration or extrusion caused by mating tolerance) is applied to the connector (20), the connector (20) will undergo a slight displacement, which causes the bent portions (31) of all the bent terminals (30) to undergo elastic deformation. When the external force disappears, the elastic restoring force of the bent portions (31) will push the connector (20) back to its initial center position. In this way, a movable connection of the connector (20) relative to the housing (10) supported by the elastic terminals is realized, i.e., a floating function.

[0027] In a more specific embodiment, such as Figures 1 to 5 As shown, the structure of the housing (10) can be further optimized to better guide and stabilize the connector (20). Multiple fixing slots (12) can be arranged at intervals on the inner walls of the two sides of the adapter groove (11). These fixing slots (12) can cooperate with the side wall structure of the connector (20) to provide initial positioning and prevent unnecessary rotation of the connector (20) in the adapter groove (11).

[0028] Meanwhile, slots (13) are provided at the bottom of both sides of the adapter slot (11) in the longitudinal direction. These slots (13) are the key structure for realizing floating stroke control, and will be described in detail in conjunction with the structure of the connector (20).

[0029] like Figures 1 to 5 As shown, the structure of the connector (20) is specially designed to provide sufficient elastic deformation space for the bent portion (31) of the bent terminal (30) and to optimize its installation path. The central region of the connector is raised upward to form a platform-shaped fixing portion (24). The fixing hole (21) for fixing the terminal is formed at the top of this fixing portion (24). The strip-shaped groove (22) for guiding the terminal path is formed on the side of the fixing portion (24). The through groove (23) for allowing the terminal to finally protrude is formed at the bottom of the entire connector (20).

[0030] This "top-side-bottom" three-dimensional layout creates an ideal "S" or "Z" shaped installation path for the bent terminal (30), allowing it to be firmly positioned while maximizing the elastic potential of its bent portion (31).

[0031] like Figures 1 to 5 As shown, the floating function is controlled by the precise fit between the housing and the connector. The connector (20) has protruding abutment portions (25) on both sides of its longitudinal direction (i.e., both ends in the length direction). When the connector (20) is installed into the adapter groove (11) of the housing (10), the abutment portion (25) abuts against and is confined within the pre-set slot (13) at the bottom of the housing (10).

[0032] This "abutting and confining within" structural relationship plays two important roles: First, it provides a guide for the floating of the connector (20), ensuring its smooth movement along a preset direction (e.g., the X and Y axes); second, the size of the slot (13) is larger than the size of the abutting part (25), and the gap between them precisely defines the maximum floating distance of the connector (20). This ensures that the connector has sufficient tolerance compensation capability while preventing permanent damage to the bent terminal (30) due to excessive displacement of the connector (20), thereby ensuring the stability of the entire connector structure and its long-term reliability.

[0033] In summary, this solution achieves the floating function of the connector through a highly integrated design that utilizes the elasticity of the terminals themselves. It has an ingenious structure, reliable performance, and high practical value.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this solution and not to limit it. Although this solution has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this solution without departing from the spirit and scope of the technical solution of this solution, and all such modifications or substitutions should be covered within the scope defined by the claims of this solution.
