[0002] Fisheye terminals are a type of press-fit terminals, which are used to be inserted into the through holes of circuit boards. During assembly, the outer surface is guided and the middle part is contracted, thereby smoothly completing the insertion process. In actual application, fisheye terminals have the advantages of small insertion force, no soldering, short process, vibration resistance, tolerance compensation, and little damage to printed circuit board holes, so they have been widely used.

[0003] The conventional fisheye terminal structure is wide in the middle and narrow at both ends, so that its cross section is not equal everywhere.

[0023] Embodiment 1

[0024] See also Figure 1 and Figure 2As shown, the present embodiment provides a fisheye terminal, which includes: a terminal body 100, the terminal body 100 includes a connecting component 110 and a guide component 120, the guide component 120 is arranged at one end of the connecting component 110 in the length direction, the connecting component 110 includes two arc-shaped deformation parts 111 arranged along its width direction, the two ends of the two deformation parts 111 are respectively connected to each other, and the middle is arranged at intervals, and a deformation space 112 is between the two deformation parts 111; an elastic recovery mechanism 200, the elastic recovery mechanism 200 is connected in the deformation space 112, and includes at least one first elastic member 210 and at least one second elastic member 220, the first elastic member 210 and the second elastic member 220 are configured as: an arc structure protruding along the thickness direction of the terminal body 100, the first elastic member 210 and the second elastic member 220 are respectively connected to the two deformation parts 111 at both ends and the protruding directions of the two are arranged in opposite directions.

[0025] The fisheye terminal described in this embodiment realizes flexible plug-in installation with the PCB board through the terminal body 100. At the same time, based on the setting of the elastic recovery mechanism 200, the present application can quickly rebound the connecting component 110 to its original position after being squeezed and deformed, thereby ensuring sufficient contact between the terminal body 100 and the board hole, which can not only improve the contact stability between the two and reduce the contact resistance, but also greatly improve the seismic stability during use. It is a new type of fisheye terminal with broad application prospects.

[0026] See also Figure 1 and Figure 2 As shown, the fisheye terminal in this embodiment also includes a connector 300, and the connector 300 and the guide assembly 120 are respectively arranged at the two ends of the connecting assembly 110 in the length direction. Specifically, the terminal body 100 is arranged at one end of the connecting body 300 in the length direction, which is used for electrical lead-out, and the guide assembly 120 is used to guide the plugging process of the terminal body 100, so that the terminal body 100 can be more easily connected to the PCB board hole, and the connecting assembly 110 is used to realize the connection and fixation of the fisheye terminal with the PCB board. Further, the terminal body 100, the elastic recovery mechanism 200 and the connector 300 in this embodiment are all integrally arranged, and the terminal body 100, the elastic recovery mechanism 200 and the connector 300 are all conductive metals. Specifically, the above three in this embodiment are preferably copper components with large elastic deformation ability and excellent conductivity. In other embodiments, the terminal body 100, the elastic restoring mechanism 200 and the connector 300 may be independently processed according to actual usage, or may be configured as other materials that are both elastic and conductive, and the present invention does not impose any specific restrictions on this.

[0027] See also Figures 1 to 3 As shown, the deformation part 111 is set as an arc-shaped structure that moves away from each other in the horizontal direction from both ends to the center, and the terminal body is gradually protruded from both sides to the center in the width direction. Therefore, the terminal body can be set in the opposite direction to the part of the elastic recovery mechanism 200 inside it, which can increase the elasticity and also improve its support strength, thereby ensuring the retention force of the plug board. Correspondingly, the deformation space 112 is set as a fisheye-shaped space that matches the two deformation parts 111. On the one hand, this shape can facilitate the dispersion of the extrusion force borne by the deformation part 111, and gradually convert the horizontal thrust along its moving direction into an inward extrusion force through the streamlined outer surface, thereby avoiding damage between the terminal body 100 and the PCB board hole due to excessive extrusion. In addition, this structural setting is also more convenient for deformation recovery.

[0028] See also Figure 2As shown, the elastic recovery mechanism 200 includes a first elastic member 210 and two second elastic members 220, wherein the two second elastic members 220 are arranged at the two ends of the length direction of the deformation space 112, and the first elastic member 210 is arranged between the two second elastic members 220. Further, the shape of the first elastic member 210 and / or the second elastic member 220 matches the deformation space 112. In this embodiment, the two second elastic members 220 have the same structural arrangement and are arranged in a mirror-symmetrical manner with the center of the two middle connecting lines in the horizontal plane. Both are configured as a structure that gradually widens from the two ends of the deformation space 112 to the middle, and the two second elastic members 220 are tightly connected to the deformation space 112 on both sides along the width direction of the deformation space 112. Specifically, the second elastic members 220 in this embodiment are arranged to protrude toward the top of the deformation space 112. Correspondingly, the first elastic member 210 is configured to have a shape that matches the middle part of the deformation space 112. Both sides of the first elastic member 210 along the width direction of the deformation space 112 are tightly connected to the deformation space 112. In the length direction of the deformation space 112, both sides of the first elastic member 210 are respectively abutted against the two second elastic members 220. Thus, the first elastic member 210 and the two second elastic members 220 can fill the interior of the deformation space 112 to achieve the optimal elastic deformation recovery effect. Furthermore, the first elastic member 210 in this embodiment is configured to protrude toward the bottom of the deformation space 112. The structural configuration in which the first elastic member 210 and the second elastic member 220 protrude in opposite directions can evenly distribute the extrusion force exerted on the deformation portion 111 while ensuring deformation and deformation recovery performance, so that it can maintain a stable balance in its thickness direction, thereby avoiding the problem of deformation or even damage of the deformation portion 111 due to the difficulty in evenly distributing the extrusion force. In other embodiments, other numbers of the first elastic members 210 and the second elastic members 220 may be provided according to actual use requirements, and the first elastic members 210 and the second elastic members 220 may also be provided at intervals at different positions, and the present invention does not impose any specific limitation on this.

[0029] See also Figure 2As shown, the guide assembly 120 includes a plug connector 121 and at least one guide slope 122. One side of the plug connector 121 is connected to one end of the connecting assembly 110 in the length direction, and the other side is fixedly connected to at least one guide slope 122. At least one guide slope 122 is arranged in a direction away from the plug connector 121 from the outer periphery of the plug connector 121 to the center. Specifically, the guide assembly 120 in this embodiment includes four guide slopes 122, and the four guide slopes 122 are evenly spaced around the outer surface of the plug connector 121. The guide slopes 122 can guide the moving direction of the terminal body 100 on the one hand, and can also reduce the front impact force on the plug connector 121 on the other hand, thereby achieving a protective effect on the plug connector 121 while facilitating installation.

At the same time, based on the setting of the elastic recovery mechanism 200, the present application can make the connecting component 110 quickly rebound to its original position after being squeezed and deformed, thereby ensuring sufficient contact between the terminal body 100 and the board hole, which can not only improve the contact stability between the two and reduce the contact resistance, but also greatly improve the seismic stability during use. It is a new type of fisheye terminal, electrical connection mechanism and sensor with broad application prospects.
