The second end opening 116 is inserted into the groove 111 .

The first sliding piece 130 corresponds to the first wall surface 114 and is slidably disposed in the groove 111 to have a first position and a second position (respectively, FIG. 3A and FIG. 3D ). The first sliding piece 130 has a plurality of first through holes 131 . In some embodiments, “sliding” means that the first slide 130 can slide along the first direction X between the first position and the second position. In some embodiments, the terminal connector 100 may include two sliding pieces, and the detailed structure will be described later.

In some embodiments, the reset element 170 is located between the cover 150 and the first sliding piece 130 , and the reset element 170 normally maintains the first sliding piece 130 at the first position. In some embodiments, the restoring element 170 is a spring, and maintains the first sliding piece 130 at the first position by elastic force. The plurality of first elastic terminals 180 are located between the first wall 114 and the first sliding piece 130 and correspond to the first through holes 131 . When the terminal connector 100 is mounted on a circuit board (such as the element 300 in FIG. 6 ), the first elastic terminal 180 is electrically connected to the circuit board. In some embodiments, the first elastic terminals 180 correspond to the first through holes 131 in a one-to-one manner. When the first sliding piece 130 is at the second position, the first elastic terminals 180 are located in the corresponding first through holes 131 and exposed to the first sliding piece 130 . The exposure here means that the lower top surface of the first elastic terminal 180 is flush with the surface of the first sliding piece 130 (the lower surface from the perspective of FIG. 3A ) or the first elastic terminal 180 protrudes from the surface of the first sliding piece 130 .

Please refer to FIG. 3A to FIG. 3F , and also refer to FIG. 2 . FIG. 3A is a schematic cross-sectional view of a first sliding piece at a first position according to an embodiment. FIG. 3B is a partial schematic view of FIG. 3A. FIG. 3C is a partial schematic diagram of FIG. 3A. FIG. 3D is a schematic cross-sectional view of the first slider at the second position according to an embodiment. FIG. 3E is a partial schematic diagram of FIG. 3D . FIG. 3F is a partial schematic diagram of FIG. 3D . In some embodiments, as shown in FIG. 3B and FIG. 3E , when the plugging device 500 is continuously inserted into the groove 111 from the second end opening 116 along the first direction X, the plugging device 500 abuts against the first sliding piece 130, as shown in FIG. 3C and FIG. 3F , the plug-in device 500 makes the first sliding piece 130 slide along the first direction X and presses the reset element 170, causing the first sliding piece 130 to slide from the first position ( FIG. 3C ) to the second position ( FIG. 3F). Next, please refer to FIG. 3F, when the first sliding piece 130 is in the second position, each first elastic terminal 180 normally has the power to push its terminal tip toward the second wall 115, so when the first through hole 131 is aligned with the first elastic Terminals 180, the tips of each of the first elastic terminals 180 will pass through the corresponding first through holes 131 and protrude from the surface of the first sliding piece 130, so that the first elastic terminals 180 and the plugging device 500 Gold fingers are electrically connected. In some embodiments, the plugging device 500 abuts against the first sliding piece 130 only after the stroke of inserting into the groove 111. Please refer to FIG. 3D and FIG. The first sliding piece 130 starts to move from the first position to the second position only when the plugging device 500 is pushed against by the plugging device 500 at a later stage of the stroke of inserting the plugging device 500 into the groove 111 . With this design, the first elastic terminals 180 gradually protrude toward the second wall surface 115 when the plugging device 500 is inserted into the groove 111 in the latter part of the stroke, so as to prevent the first elastic terminals 180 from being exposed to the first elastic terminal 180 prematurely. The sliding piece 130 is in contact with the golden finger of the plugging device 500 to generate friction. In some embodiments, as shown in FIG. 3C , the distance between the first position and the second position is the first distance L1, the distance between two adjacent first elastic terminals 180 is the second distance L2, and the first distance L1 is less than 1.8 times the second distance L2, therefore, when the plug-in device 500 pushes against the first sliding piece 130 so that the first elastic terminals 180 are exposed to the first through-hole 131, the first elastic terminals 180 will not correspond to the non-corresponding The gold fingers of the plug-in device 500 are in contact, so as to avoid unnecessary electrical connection. In some embodiments, the first distance L1 is substantially the same as or smaller than the second distance L2, which can ensure that the first elastic terminals 180 are only in contact with the corresponding golden fingers.

Specifically, when the plug-in device 500 is inserted into the terminal connector 100 along the first direction X, the first sliding piece 130 is pressed against the reset member 170 by the plug-in device 500 and overcomes the elastic force of the reset member 170, The first sliding piece 130 slides from the first position to the second position. When the first sliding piece 130 is at the second position, the first elastic terminals 180 are aligned and located in the corresponding first through holes 131 and exposed to the first sliding piece 130, so that the terminal connector 100 can be connected with the plugging device 500 electrical connection. When the plug-in device 500 withdraws from the terminal connector 100 along the opposite direction of the first direction X, the first sliding piece 130 is no longer supported by the plug-in device 500, and the reset element 170 recovers due to its own elastic force, so that The first sliding piece 130 slides from the second position to the first position to release the electrical connection between the terminal connector 100 and the plugging device 500 .

In addition, when the plug-in device 500 is inserted into the terminal connector 100 along the first direction X, the first elastic terminals 180 have not passed through the first through holes 131, therefore, the gold finger of the plug-in device 500 The first elastic terminals 180 are not in contact with each other, so as to prevent the first elastic terminals 180 from rubbing against the gold finger and causing the gold finger to be worn. When the plug-in device 500 is inserted to the side of the first end opening 113 (as shown in FIG. 3F ) and the first sliding piece 130 is pushed, the first elastic terminals 180 pass through the corresponding first through holes 131 one after another and are exposed. On the first sliding piece 130 , at this time, the first elastic terminals 180 are electrically connected to the corresponding golden fingers. In addition, when the plug-in device 500 withdraws from the terminal connector 100 along the opposite direction of the first direction X, the first sliding piece 130 gradually moves to the left in FIG. Gradually retract from the corresponding first through holes 131, so that the first elastic terminals 180 are out of contact with the golden fingers of the plug-in device 500, so that the plug-in device 500 will not come into contact with these plug-in devices during the withdrawal process. The first elastic terminal 180 generates friction.

When in use, the user can manually method, first move the first sliding piece 130 to the position in FIG. Before the bump 133, the first sliding piece 130 can prevent the first elastic terminals 180 from rubbing against the golden finger during the insertion of the plug-in device 500. When the plug-in device 500 is to be pulled out, the user can directly To pull out the plug-in device 500, the first sliding piece 130 can also be manually pushed back to the first position when the plug-in device 500 has just been pulled out for a short distance (for example, the aforementioned pulling-out stroke is greater than or equal to the first distance L1), In this way, it is possible to prevent the first elastic terminal 180 from rubbing against the golden finger when the plugging device 500 is pulled out. This embodiment is applicable to non-hot plugging devices.

In some embodiments, the first elastic terminal 180 corresponding to the long slot hole 131A is a ground terminal 180A. In order to enable the ground terminal 180A to be electrically connected to the electronic terminal (commonly known as gold finger) on the plug-in device 500 earlier and to be separated from the electronic terminal of the plug-in device 500 later, the long slot 131A corresponding to the ground terminal 180A has a The larger size D. In some embodiments, the first elastic terminal 180 is an assembly of multiple components. The first elastic terminal 180 includes a terminal piece, an elastic piece, and a base. The terminal piece is assembled on the base through the elastic piece, so that the terminal piece is supported by the elastic piece. Influenced by the elastic force, it is pushed out normally.

When the plugging device 500 is inserted into the terminal connector 100 along the first direction X, the first guiding portion 132 guides the first elastic terminal 180 along the first direction X into the first through hole 131 . When the plugging device 500 withdraws from the terminal connector 100 along the direction opposite to the first direction X, the first guiding portion 132 guides the first elastic terminal 180 to withdraw from the first through hole 131 along the direction opposite to the first direction X. As shown in FIG. 4A , the first guiding portion 132 is a slope, but not limited thereto. In some embodiments, as shown in FIG. 4C , the first guiding portion 132 may also be a curved surface.

Please refer to FIG. 4A , in some embodiments, the stroke L of the first guiding portion 132 of at least one of the first through holes 131 is shorter than the stroke of the other first guiding portion 132 of the first through holes 131 l. Here, the first guiding portion 132 of at least one of the first through holes 131 is the first guiding portion 132A, and the other first guiding portion 132 of the first through holes 131 is the first guiding portion 132A. 132B, the stroke L of the first guide portion 132A is shorter than the stroke 1 of the first guide portion 132B. Specifically, the first guiding portion 132A and the first guiding portion 132 start from the same guiding position, and the first guiding portion 132A guides the first elastic terminal 180 into the first through hole 131 along the first direction X. The stroke L is smaller than the stroke l of the first guide portion 132B guiding the first elastic terminal 180 into the first through hole 131 along the first direction X. In some embodiments, the first guide part 132B is the guide part of the slot hole 131B, and the first guide part 132A is the guide part of the long slot hole 131A and corresponds to the ground terminal 180A, so that the ground terminal 180A can be compared with the ground terminal 180A. It is electrically connected to the plug-in device 500 early, and is separated from the plug-in device 500 later. For the plug-in device 500 using hot-swapping, the long slot 131A makes the ground terminal 180A electrically connected to the plug-in device 500 (the ground pin in the golden finger) earlier than other signal terminals electrically connected to the plug-in device 500. device 500. Similarly, when the plug-in device 500 is pulled out, the ground terminal 180A also breaks away from the electrical connection with the plug-in device 500 later. In this way, during the hot plugging process of the plugging device 500 and the terminal connector, the electrical signal will be more stable, and the noise of the electrical signal will be reduced.

In some embodiments, the first through holes 131 with a shorter stroke are located on the outermost side of the first through holes 131 . Specifically, the slotted hole 131A is located at the outermost side of the first through holes 131 , on the side of the first end opening 113 as shown in FIG. 3C . In some embodiments, the side of the second end opening 116 as shown in FIG. 3B may also be provided with a long slot 131A, or only one of the outermost sides is provided with a long slot 131A. The embodiment in which the long slot holes 131A are located at the outermost sides of the first through holes 131 can further reduce the noise of the electrical signal. In another embodiment, when the elastic terminal has a differential signal terminal, the slot 131A is located on both sides of the pair of differential signal terminals.

See Figure 5A. FIG. 5A is an exploded view (1) of another implementation of the terminal connector according to an embodiment.
