Description

Technical Field

[0001] This utility model relates to the field of connectors, specifically to a double-row fisheye terminal connector. Background Technology

[0002] Metal terminals are the core metal components in connectors that enable electrical conduction and mechanical fixation. Their design directly affects the performance, lifespan, and reliability of the connector. To improve connector performance, metal terminals used in high-density, high-current, or multi-signal transmission scenarios often employ a two-row parallel design. Because the two rows of terminals are in contact simultaneously, the insertion and extraction force is significantly increased compared to a single row of terminals. This can accelerate terminal wear during insertion and extraction, resulting in lower connection reliability. Utility Model Content

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] Please see Figure 1-4 The preferred embodiment of this utility model provides a double-row fisheye terminal connector, including a housing 1 and a plurality of metal terminals 2. The plurality of metal terminals 2 are divided into two rows of equal number and are arranged opposite to each other. The arrangement of the double-row metal terminals 2 can disperse the mechanical stress during insertion, removal or vibration, reduce the risk of deformation or poor contact caused by uneven force, and the arrangement of the double-row metal terminals 2 can form a more stable physical support, thereby enhancing the reliability of the connection.

[0025] Specifically, the hardware terminal 2 includes two support arms 21 connected at the ends. The connection point of the two support arms 21 is located inside the housing 1. The end of the support arms 21 connected to each other is the first connection end 211, and the other end is the second connection end 212. The second connection end 212 extends out of the side of the housing 1 and is provided with a fisheye hole 213. The second connection end 212 is used to connect with external components. Furthermore, when the second connection end 212 with the fisheye hole 213 is inserted into the through hole, it will deform and generate radial tension, thereby tightly adhering to the hole wall and preventing the second connection end 212 from loosening and falling off due to vibration or external force, further enhancing the connection reliability.

[0026] In this embodiment, the two support arms 21 are integrally bent and formed, and the included angle between the two support arms 21 is an obtuse angle. The connection between the two arms is firm, and the overall structure is more uniform, with better compressive, tensile, and fatigue resistance. Furthermore, the obtuse angle between the two support arms 21 facilitates bending and reduces the likelihood of metal breakage during bending, thus lowering the scrap rate.

[0027] The support arm 21 has two protrusions 214, which are positioned opposite each other on both sides of the support arm 21. The center of the fisheye hole 213 is located between the two protrusions 214. During the process of inserting the hardware terminal 2 into the through hole of the external component, the protrusions 214 make it easier for the support arm 21 to abut against the inner wall of the through hole, making it easier for the support arm 21 to be snapped into the through hole, increasing the firmness of the snap-fit ​​and making it less likely to fall off.

[0028] The outer shell 1 is wedge-shaped, with an inclined surface 11 and a bottom surface 12 adjacent to the inclined surface 11. Two support arms 21 are respectively inserted through the inclined surface 11 and the bottom surface 12. In use, the two support arms 21 can respectively cooperate with through holes set on surfaces with different inclination angles, thus expanding the application range of the connector.

[0029] More specifically, the two support arms 21 are perpendicular to the inclined surface 11 and the bottom surface 12, respectively. The second connecting end 212 is provided with chamfers 215 on all four sides. The chamfers 215 make it easy for the support arms 21 to be inserted into the through holes of external components. The vertical arrangement allows the inclined surface 11 or the bottom surface 12 on the housing 1 to fit against the surface of the external components with through holes, further providing support and preventing the connector from falling off.

[0030] Both the inclined surface 11 and the bottom surface 12 are provided with connecting holes 111. The support arm 21 passes through the connecting hole 111 and is interference-fitted with the connecting hole 111, so that the two are tightly connected. The connecting hole 111 can limit the support arm 21 and prevent it from deflecting. In this embodiment, both the connecting hole 111 and the support arm 21 have square cross-sections. Square cross-sections have better bending and torsional resistance, are less prone to deformation in insertion, removal or vibration environments, and the right-angled edges can provide stronger mechanical support and withstand lateral forces.

[0031] A PCB board (not shown in the figure) is housed inside the outer casing 1. The PCB board is connected to the hardware terminals 2. The PCB board is used for mechanical support and electrical connection of electronic components, while the hardware terminals 2 are used for transmitting electrical signals or power from the PCB board. In this embodiment, the outer casing 1 is integrally formed with the PCB board and the hardware terminals 2 by overmolding. After the hardware terminals 2 are fixed to the PCB board, overmolding is performed around the PCB board, forming the outer casing 1 that covers the PCB board, providing high protection for the PCB board and improving the overall compactness of the connector.

[0032] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
