Please refer to fig. 1A, fig. 1B and fig. 2A. The connector includes a terminal plate 10 and an insulating housing 20. The terminal piece 10 includes a bending section 11, a butt-joint section 12 and a plug-in section 13. The bending section 11 is connected to the docking section 12 and the insertion section 13 and is located between the docking section 12 and the insertion section 13. In some embodiments, the docking section 12 has a docking shaft L1, and the docking section 13 includes a docking shaft L2 and a protrusion 14. The plug axis L2 intersects the docking axis L1 in such a way that the docking section 12 and the plug section 13 enclose an angle α with one another. In some embodiments, the angle α formed by the docking section 12 and the plugging section 13 is preferably 90 degrees. In some embodiments, the tab 14 extends upward (above in fig. 2A) along the insertion axis L2, whereby the top of the tab 14 corresponds to the docking section 12. Wherein the top of bumps 14 may be a top end or a top plane. In some embodiments, the top of the bump 14 is substantially aligned with the top of the docking section 12 and is not higher than the top of the docking section 12, i.e., the top of the bump 14 and the top of the docking section 12 are substantially in the same plane. In some embodiments, the top of the protrusion 14 protrudes above the top of the docking station 12 by a predetermined distance above the docking station 12. This predetermined distance allows the top of bump 14 to approach or contact top 24 (described in more detail below). In some embodiments, after the inserting section 13 needs to receive an external force, the top of the protrusion 14 is coupled to approach or contact the abutting portion 24 of the base, and when the top of the protrusion 14 contacts the abutting portion 24 of the base, the abutting effect is provided to prevent the inserting section 13 from being deformed due to the external force.

Further, when the terminal piece 10 is located on the insulating base 20, the inserting section 13 is located in the accommodating space 23, and the abutting portion 24 corresponds to the protruding block 14, so that the protruding block 14 can abut against or contact with the abutting portion 24, and when the protruding block 14 abuts against or contacts the abutting portion 24, the inserting section 13 is abutted by the abutting portion 24, thereby avoiding the deformation of the inserting section 13 due to stress.

The abutting portion 31 is connected to the base 21. In some embodiments, the docking portion 31 includes two opposing docking sidewalls 32 and a docking space 33 between the docking sidewalls 32, the docking space 33 is communicated with the accommodating space 23, and the docking section 12 is located in the docking space 33. Further, when the terminal piece 10 is located in the insulating housing 20, the docking section 12 is located in the docking space 33 and located in a different space from the plugging section 13. In some embodiments, when the terminal plate 10 is located in the insulating housing 20, the docking section 12 is partially located in the docking space 33 and partially located in the accommodating space 23.

Referring again to fig. 3B, in some embodiments, base 21 includes a top wall 25 and opposing portion 24 includes top wall 25. Further, when the terminal piece 10 is located in the insulating housing 20, the abutting portion 24 located on the top wall 25 corresponds to the protrusion 14, so that the protrusion 14 can abut against or contact with the abutting portion 24.

Referring to fig. 1A, fig. 1B and fig. 3B, in some embodiments, the connector includes a plurality of terminal pieces 10, the docking portion 31 includes a plurality of partition plates 34, the partition plates 34 partition the docking space 33 into a plurality of docking passages 33a, the docking sections 12 of the terminal pieces 10 are respectively located in the docking passages 33a, for example, one partition plate 34 is preferred, the terminal pieces 10 are preferably four, the partition plates 34 partition the docking space 33 into two docking passages 33a, the docking sections 12 of the four terminal pieces 10 are respectively located in the docking passages 33a in pairs, and the partition plates 34 are arranged so that the terminal pieces 10 are respectively located in the docking passages 33a without mutual interference.

In some embodiments, one of the seat sidewalls 22 includes a plurality of guiding grooves 27, the guiding grooves 27 are respectively connected to the limiting grooves 26, and the depth of each guiding groove 27 is deeper than the depth of the corresponding limiting groove 26. Further, when the inserting section 13 is to be placed in the accommodating space 23, the placing track of the inserting section 13 can be more stabilized by the arrangement of the guiding groove 27, and when the limiting portion 15 reaches the limiting groove 26, since the depth of the limiting groove 26 is shallower, in other words, the depth of the limiting groove 26 is shallower than the guiding groove 27, when the limiting portion 15 pushes against the limiting groove 26, the limiting portion 15 will push against the limiting groove 26, and the inserting section 13 can be more stabilized in the accommodating space 23.

Referring to fig. 2A and 4A, in some embodiments, each plug section 13 includes a plug end 16 at the other end opposite to the corresponding bending section 11, and the distance between the limiting portion 15 of different plug sections 13 and the corresponding plug end 16 is different. Furthermore, the plugging section 13 of each terminal piece 10 includes a limiting portion 15, and the distances from the limiting portions 15 on different terminal pieces 10 to the corresponding plugging ends 16 are different, so that the limiting portions 15 on different terminal pieces 10 are not at the same horizontal position.

In some embodiments, the base 21 further includes a vertical wall 28, and the distance from the limiting portion 15 farther away from the vertical wall 28 to the corresponding plug end 16 is shorter than the distance from the limiting portion 15 closer to the vertical wall 28 to the corresponding plug end 16. Therefore, the limiting parts 15 on different terminal pieces 10 are not in the same horizontal position. Further, as shown in fig. 4A, the stopper 15 is arranged from top left to bottom right.

Therefore, the limiting parts 15 on different terminal pieces 10 are not in the same horizontal position. Further, as shown in fig. 4B, the stopper 15 is arranged from the upper right to the lower left. Accordingly, in the present embodiment, the positions of the plurality of stopper grooves 26 of the seat side wall 22 are set corresponding to the positions of the stopper portions 15 in the present embodiment.

In some embodiments, two positioning portions 17 of the docking portion 12 of each terminal piece 10 are preferably located at corresponding positions on two sides of the docking portion 12 in pairs, and each of the two docking sidewalls 32 includes a positioning groove 35 at the corresponding position, so that when the docking portion 12 is located in the docking space 33, each positioning portion 17 abuts against the positioning groove 35. In some embodiments, the docking portion 12 of each terminal piece 10 includes a plurality of pairs of positioning portions 17, and the positioning groove 35 is disposed corresponding to the positions of the pairs of positioning portions 17.
