Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a fisheye terminal. Background Art

[0002] With the continuous development of the network communication industry, electronic products and communication products are becoming more and more popular. In the process, the demand for high-end connectors is also increasing.

[0003] Fisheye pins are a new type of terminal commonly found in communication connectors. When inserted into a PCB's socket, two opposing elastic arms are squeezed by the socket, causing elastic deformation. This allows the pin to connect to the PCB, establishing an electrical connection and transmitting signals. However, existing fisheye pins often damage the PCB's socket due to the insufficient strength of the elastic arms. Alternatively, the hollow fisheye structure between the elastic arms during processing can result in a loose connection, which in turn affects the reliability of the connection.

[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a fisheye terminal. In order to solve at least the above technical problems, this utility model adopts the following technical solutions:

[0006] A fisheye terminal is provided with a plug-in portion, an elastic portion, and a needle rod portion in sequence along the axial direction. The elastic portion includes two elastic arms arranged opposite to each other, and the two ends of the two elastic arms are respectively connected to the plug-in portion and the needle rod portion. A deformation space is defined between the two elastic arms, and a spacer is provided in the middle of the deformation space. The spacer divides the deformation space into two independent fisheye blind holes; an inclined weakening surface is provided on the outer surface of each of the two elastic arms, and the weakening surface is provided on at least one end face of the elastic arm along the thickness direction.

[0007] Furthermore, the fisheye blind hole includes a deformation portion and transition portions located at both ends of the deformation portion. The two transition portions are symmetrically arranged along the deformation portion, and the width of the transition portion gradually decreases as the transition portion gradually moves away from the deformation portion.

[0008] Furthermore, the axes of the two elastic arms are arranged as convex arcs toward the outside, so that the width between the outer surfaces of the two elastic arms gradually decreases from the middle to the two ends, and the weakened surface is arranged in the middle section of the elastic arm.

[0009] Furthermore, the outer surface of the elastic arm is configured as an arc-shaped surface along the length direction, and the weakened surface and the outer surface of the elastic arm define an abutting surface at relative positions.

[0010] Furthermore, the inner side wall of the fisheye blind hole is configured as a gradually outwardly expanding arc surface from the spacer to the fisheye blind hole opening.

[0011] Furthermore, a surface of the spacer facing the opening of the fisheye blind hole is provided with a curved surface having the same curvature as the inner sidewall surface of the fisheye blind hole.

[0012] Furthermore, the end of the plug-in portion is configured as a conical structure.

[0013] Furthermore, a connecting portion is provided on at least one side surface of the needle rod portion, and the connecting portion includes a protrusion formed on the needle rod portion and a groove adjacent to the protrusion.

[0014] The beneficial effects produced by the utility model are as follows:

[0015] The fisheye terminal provided by the embodiment of the utility model improves the rigidity of the elastic portion by providing a spacer, thereby being able to resist the elastic deformation of the elastic arm, thereby increasing the elastic force of the elastic portion and ensuring a tight and reliable abutment with the plug hole during the plugging process. At the same time, a weakening surface is provided on the elastic arm to weaken the strength of the elastic arm, so that when the elastic portion is compressed by the plug hole, it can quickly undergo elastic deformation, thereby avoiding damage to the PCB board due to the large elastic force. The fisheye terminal provided by this embodiment balances the elastic force and strength of the elastic portion, enabling the terminal to have sufficient elastic force while also being able to quickly undergo elastic deformation when the elastic arm is compressed by the plug hole, thereby ensuring that the fisheye terminal is firmly abutted against the plug hole during plugging and avoiding damage to the PCB board.

DETAILED DESCRIPTION

[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0021] The embodiment of the present invention provides a new type of fisheye terminal. Through the structural design of the elastic part 200, it can ensure that the elastic part 200 has sufficient elastic deformation ability, ensuring that they can be firmly plugged into the PCB board during the process of mutual plugging. At the same time, it can avoid damage to the PCB board due to the excessive strength of the elastic arm 210.

[0022] like Figure 1-3 As shown, an embodiment of the present invention provides a fisheye terminal, which is provided with a plug-in portion 100, an elastic portion 200, and a needle rod portion 300 in sequence along the axial direction. The elastic portion 200 includes two elastic arms 210 arranged opposite to each other, and the two ends of the two elastic arms 210 are respectively connected to the plug-in portion 100 and the needle rod portion 300. A deformation space is defined between the two elastic arms 210, and a spacer 211 is provided in the middle position of the deformation space. The spacer 211 divides the deformation space into two independent fisheye blind holes 212; an inclined weakening surface 213 is provided on the outer surface of the two elastic arms 210, and the weakening surface 213 is provided on at least one end face of the elastic arm 210 along the thickness direction.

[0023] A spacer 211 is provided between the two elastic arms 210, thereby connecting the two elastic arms 210 and forming fisheye blind holes 212 on both sides of the elastic part 200. During the process of plugging with the PCB board, the spacer 211 can increase the resistance of the two elastic arms 210 to elastic deformation toward the middle, so that the elastic force of the elastic part 200 is increased, which can ensure a large compressive force between the PCB board, thereby ensuring a firm plugging and stable signal transmission. More importantly, in order to avoid damage to the PCB board due to the large elastic force of the elastic part 200 when the terminal is plugged into the PCB board, a weakening surface 213 is provided on the elastic arm 210, thereby reducing the size of the elastic arm 210 and the strength of the elastic arm 210, so that it can quickly undergo elastic deformation when subjected to pressure.

[0024] The fisheye terminal provided by the embodiment of the present invention improves the rigidity of the elastic portion 200 by providing a spacer 211, thereby resisting the elastic deformation of the elastic arm 210, thereby increasing the elastic force of the elastic portion 200 and ensuring a tight and reliable abutment with the plug hole during the plugging process. At the same time, a weakening surface 213 is provided on the elastic arm 210 to weaken the strength of the elastic arm 210, so that when the elastic portion 200 is pressed by the plug hole, it can quickly undergo elastic deformation, thereby avoiding damage to the PCB board due to the large elastic force. The fisheye terminal provided by this embodiment balances the elastic force and strength of the elastic portion 200, so that the terminal has sufficient elastic force while being able to quickly undergo elastic deformation when the elastic arm 210 is pressed by the plug hole, thereby ensuring that the fisheye terminal abuts tightly with the plug hole during plugging and avoiding damage to the PCB board.

[0025] In this embodiment, the fisheye blind hole 212 includes a deformation portion 214 and transition portions 215 located at both ends of the deformation portion 214. The two transition portions 215 are symmetrically arranged along the deformation portion 214. The width of the transition portion 215 gradually decreases as the transition portion 215 gradually moves away from the deformation portion 214.

[0026] At the same time, the axes of the two elastic arms 210 are arranged along outwardly convex arcs, so that the width between the outer surfaces of the two elastic arms 210 gradually decreases from the middle to the ends. The weakened surface 213 is located in the middle of the elastic arms 210. In other words, the weakened surface 213 is located at the location of the deformed portion 214. During the plugging process, the deformed portion 214 is the location where the primary elastic deformation occurs. When pressed by the plug hole, the elastic arm 210 can quickly deform, causing the deformed portion 214 to be squeezed inward, thereby plugging into the plug hole.

[0027] In this embodiment, the outer surface of the elastic arm 210 is configured as an arc-shaped surface along the length direction, and the weakened surface 213 and the outer surface of the elastic arm 210 define a contact surface 216 at a relative position. Figure 2 As shown, the outer surface of the elastic arm 210 is set to an arc-shaped surface, so that when the elastic arm 210 is gradually inserted into the plug-in hole, the elastic arm 210 is elastically deformed to a greater extent under the pressure of the plug-in hole, thereby gradually increasing the elastic force. At this time, the force between the abutting surface 216 and the inner wall of the plug-in hole gradually increases, thereby ensuring the reliability of the terminal plug-in.

[0028] In this embodiment, the inner sidewall of the fisheye blind hole 212 is configured as a gradually outwardly expanding arc surface from the partition 211 to the opening of the fisheye blind hole 212. At the same time, the surface of the partition 211 facing the opening of the fisheye blind hole 212 is configured with an arc surface with the same arc as the inner sidewall surface of the fisheye blind hole 212. Figure 3As shown, the cross-section of the spacer 211 is narrower in the middle and gradually increases in thickness at both ends. At the same time, the thickness of the elastic arm 210 is the largest in the middle and gradually decreases at the upper and lower ends. This structure can enable the elastic arm 210 to deform quickly when the elastic arm 210 is compressed, thereby avoiding damage to the PCB board due to excessive elastic force.

[0029] In order to facilitate plugging, the end of the plug-in portion 100 is configured as a tapered structure.

[0030] In this embodiment, to enable the terminal to connect to external components, a connecting portion 310 is provided on at least one side surface of the needle portion 300. The connecting portion 310 includes a protrusion 311 formed on the needle portion 300 and a groove 312 adjacent to the protrusion 311. During connection with the plastic part, the plastic part is typically connected to the needle portion 300 through injection molding. The connecting portion 310 is injection-molded into the plastic part. The protrusion 311 and the groove 312 ensure a tighter connection between the plastic part and the needle portion 300, preventing the needle portion 300 from falling off the plastic part.

Although the present invention is disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention.
