After the first side wall 13 and the second side wall 14 are inserted into place, the first protruding portion 321 and the second protruding portion 331 abut against each other and spread the first side wall 13 and the second side wall 14 close to the second end 12 outwards, so that the first side wall 13 and the second side wall 14 close to the second end 12 are in contact with the hole wall 52 of the conductive hole 51, that is, the contact area between the first side wall 13 and the second side wall 14 and the hole wall 52 of the conductive hole 51 is increased, the impedance between the first side wall 13 and the second side wall 14 and the connecting piece 5 is further reduced, the impedance performance of the electrical connection assembly is further improved, deformation of the first side wall 13 and the second side wall 14 is reduced or further deformation of the first side wall 13 and the second side wall 14 is limited, excessive deformation of the first side wall 13 and the second side wall 14 is prevented, the holding force between the first side wall 13 and the second side wall 14 and the conductive hole 51 is further improved, and the matching stability of the first side wall 13 and the second side wall 14 and the conductive hole 51 is further improved.

The first and second bosses 321 and 331 may be disposed near the junction of the first and second openings 41 and 42. The width of the first opening 41 is preferably larger than the width of the second opening 42 in the width direction of the press-in type terminal 100, that is, the structural strength of the first side wall 13 and the second side wall 14 at the first opening 41 is weaker, and the first side wall 13 and the second side wall 14 at the first opening 41 are also more easily deformed, so that the resistance when the press-in type terminal 100 is inserted into the conductive hole 51 is reduced, ensuring that the press-in type terminal 100 is smoothly inserted into the conductive hole 51.

At least the corresponding position of the connecting part 3 is provided with a step structure 17, and the connecting part 3 is integrally connected with the step structure 17. Referring to fig. 1, 7 and 9, in the first, third and fourth embodiments, the step structures 17 may be provided at both sides of the connection portion 3 in the thickness direction of the press-in terminal 100. Referring to fig. 4, in the second embodiment, the step structure 17 may be provided only on one side of the connection portion 3 in the thickness direction of the press-in terminal 100. When the first and second side walls 13 and 14 are deformed, the structural strength of the connecting portion 3 can be ensured, the risk of breakage at the connection between the connecting portion 3 and the side wall 1 can be prevented, and at the same time, the first and second side walls 13 and 14 can be prevented from being excessively deformed.

Referring to fig. 1, 4 and 7, in the first, second and third embodiments, the maximum expansion 16 of the side wall 1 in the width direction of the press-in terminal 100 is provided corresponding to the opening 4, that is, the maximum expansion 16 of the first side wall 13 and the second side wall 14 is provided corresponding to the opening 4. During the process of inserting the first side wall 13 and the second side wall 14 into the conductive hole 51, the opening 4 can ensure that the maximum expansion part 16 of the first side wall 13 and the second side wall 14 has elastic deformation force, reduce the resistance when the press-in terminal 100 is inserted into the conductive hole 51, and ensure that the press-in terminal 100 is smoothly inserted into the conductive hole 51.

Preferably, the maximum expansion 16 of the side wall 1 in the width direction of the press-in terminal 100 is provided corresponding to the first opening 41, that is, the maximum expansion 16 of the first side wall 13 and the second side wall 14 is provided corresponding to the first opening 41. Further, the maximum expansion 16 of the side wall 1 in the width direction of the press-in terminal 100 is provided corresponding to the widest part of the first opening 41 in the width direction of the press-in terminal 100, that is, the maximum expansion 16 of the first side wall 13 and the second side wall 14 is provided corresponding to the widest part of the first opening 41.

Referring to fig. 9, in the fourth embodiment, the maximum expansion 16 of the side wall 1 in the width direction of the press-in terminal 100 is provided corresponding to the first connection portion 31, that is, the maximum expansion 16 of the first side wall 13 and the second side wall 14 is provided corresponding to the first connection portion 31. During the process of inserting the first side wall 13 and the second side wall 14 into the conductive hole 51, the opening 4 can ensure that the maximum expansion part 16 of the first side wall 13 and the second side wall 14 has elastic deformation force, reduce the resistance when the press-in terminal 100 is inserted into the conductive hole 51, and ensure that the press-in terminal 100 is smoothly inserted into the conductive hole 51. When inserted in place, the maximum expansion 16 is engaged with the conductive hole 51 and prevents the first and second side walls 13 and 14 from being excessively deformed by the elastic restoring force of the first connection portion 31, so that the holding force of the position can be further enhanced. Therefore, the structure has the advantages that the insertion force of the press-in type terminal 100 is reduced, and after the press-in type terminal 100 is inserted into the conductive hole 51, the abutting force between the first side wall 13 and the second side wall 14 and the conductive hole 51 is improved, so that the consistency and stability of the matching of the first side wall 13 and the second side wall 14 with the conductive hole 51 are improved.

When the position and length of the first connecting portion 31 are unchanged, the closer the maximum expansion 16 of the side wall 1 in the width direction of the press-in terminal 100 is to the first end 11 of the side wall 1, the stronger the elastic restoring force of the first connecting portion 31 after insertion into place, the stronger the holding force of the maximum expansion 16 of the side wall 1 in the width direction of the press-in terminal 100.

When the position of the maximum expansion 16 of the side wall 1 in the width direction of the press-fit terminal 100 is unchanged, the longer the length of the first connecting portion 31, the stronger the elastic restoring force of the first connecting portion 31 after insertion into place, the stronger the holding force of the maximum expansion 16 of the side wall 1 in the width direction of the press-fit terminal 100.

Referring to fig. 3, in the first, third, and fourth embodiments, in the thickness direction of the press-in terminal 100 perpendicular to the width direction, the connection portion 3 may be provided near the middle position of the side wall 1. In the present embodiment, the connecting portion 3 is provided at the intermediate position of the side wall 1 in the thickness direction of the press-in terminal 100, so that the structural strength of the side wall 1 on both sides of the connecting portion 3 can be ensured to be the same or substantially the same. In the process of inserting the side walls 1 into the conductive holes 51, the side walls 1 on both sides of the connection portion 3 can be deformed synchronously, and the deformation directions are the same or approximately the same, that is, the shrinkage deformation is performed along the width direction of the press-in terminal 100, so that dislocation of the first side wall 13 and the second side wall 14 in the up-down direction is avoided, the first side wall 13 and the second side wall 14 can be kept stably connected with the conductive holes 51, and the first side wall 13 and the second side wall 14 can be prevented from relatively moving or twisting in the up-down direction to damage the conductive holes 51.

Referring to fig. 6, in the second embodiment, in the thickness direction of the press-in terminal 100 perpendicular to the width direction, the connection portion 3 is disposed offset to one side near the side wall 1, that is, the connection portion 3 is disposed near the upper surface or the lower surface of the side wall 1. In the present embodiment, the connection portion 3 is provided on the upper surface or the lower surface of the side wall 1 in the thickness direction of the press-in terminal 100, that is, the connection portion 3 is provided flush with the upper surface or the lower surface of the side wall 1. In the process of inserting the side wall 1 into the conductive hole 51, the first side wall 13 and the second side wall 14 are rotationally deformed along the other side of the thickness direction of the press-in terminal 100 under the extrusion of the hole wall 52 of the conductive hole 51, so that the elastic deformation space of the first side wall 13 and the second side wall 14 is increased, and the stress of the first side wall 13 and the second side wall 14 can be dispersed, so that the conductive hole 51 with a wider diameter range is suitable, and the applicability of the press-in terminal 100 is improved.

Referring to fig. 7 and 8, in the third embodiment, the first sidewall 13 may be provided with a first thinning region 131, and the thickness of the first sidewall 13 at the corresponding position of the first thinning region 131 is smaller than the thickness of the rest positions of the first sidewall 13, so as to reduce the resistance of the first sidewall 13. That is, the dimension of the first sidewall 13 at the corresponding position of the first thinned region 131 is smaller than the dimension of the remaining position of the first sidewall 13, that is, the thickness of the first sidewall 13 at the corresponding position of the first thinned region 131 is smaller than the thickness of the remaining position of the first sidewall 13 in the thickness direction of the press-in type terminal 100, or the thickness of the first sidewall 13 at the corresponding position of the first thinned region 131 is smaller than the thickness of the remaining position of the first sidewall 13 in the width direction of the press-in type terminal 100. The first thinning region 131 can reduce the structural strength of the first sidewall 13, so that the resistance when the first sidewall 13 is inserted into the conductive hole 51 can be reduced, and the first sidewall 13 is ensured to be smoothly inserted into the conductive hole 51.

Referring to fig. 7 and 8, a second thinning region 141 may also be disposed on the second sidewall 14, where the thickness of the second sidewall 14 at a position corresponding to the second thinning region 141 is smaller than the thickness of the remaining positions of the second sidewall 14, so as to reduce the resistance of the second sidewall 14. That is, the dimension of the second sidewall 14 at the position corresponding to the second thinning region 141 is smaller than the dimension of the rest of the second sidewall 14, that is, the thickness of the second sidewall 14 at the position corresponding to the second thinning region 141 is smaller than the thickness of the rest of the second sidewall 14 in the thickness direction of the press-in type terminal 100, or the thickness of the second sidewall 14 at the position corresponding to the second thinning region 141 is smaller than the thickness of the rest of the second sidewall 14 in the width direction of the press-in type terminal 100. The second thinning region 141 can reduce the structural strength of the second sidewall 14, so that the resistance of the second sidewall 14 inserted into the conductive via 51 can be reduced, and the second sidewall 14 can be smoothly inserted into the conductive via 51.

Preferably, the first and second thinning regions 131 and 141 are simultaneously provided on the first and second sidewalls 13 and 14, respectively, so that the structural strength of the first and second sidewalls 13 and 14 can be ensured to be the same or substantially the same. In the process of inserting the first side wall 13 and the second side wall 14 into the conductive hole 51, the first side wall 13 and the second side wall 14 can be deformed synchronously, and the abutting force of the first side wall 13 and the second side wall 14 to the hole wall 52 of the conductive hole 51 is the same or approximately the same, so that the first side wall 13 and the second side wall 14 can be kept stably connected with the conductive hole 51, and the first side wall 13 and the second side wall 14 can be prevented from relatively moving or twisting in the vertical direction so as to damage the conductive hole 51.

Further, the first sidewall 13 is formed with a first shoulder 132 at the first thinned region 131 near the first end 11. The thickness of the first side wall 13 of the first shoulder 132 is greater than the thickness of the other portions of the first side wall 13 in the thickness direction of the press-in terminal 100. When the first sidewall 13 is inserted into the conductive hole 51, the first shoulder 132 may be clamped to the outer surface of the connector 5, so as to prevent the first sidewall 13 from being inserted too deeply.

In the first, second and fourth embodiments, the first sidewall 13 may also be provided with the first thinned region 131 and formed with the first shoulder 132. In the second embodiment, the upper surface of the first side wall 13 may be provided with the first shoulder 132 or the lower surface of the first side wall 13 may be provided with the first shoulder 132. In the first, third, and fourth embodiments, the upper and lower surfaces of the first sidewall 13 are provided with the first shoulder 132 at the same time.

The second sidewall 14 is formed with a second shoulder 142 near the first end 11 at the second thinned region 141. The thickness of the second side wall 14 of the second shoulder 142 is greater than the thickness of the other portions of the second side wall 14 in the thickness direction of the press-in terminal 100. When the second sidewall 14 is inserted into the conductive hole 51, the second shoulder 142 may be clamped to the outer surface of the connector 5, so as to prevent the second sidewall 14 from being inserted too deeply.

In the first, second and fourth embodiments, the second sidewall 14 may also be provided with a second thinned region 141 and a second shoulder 142 formed thereon. In the second embodiment, the upper surface of the second side wall 14 may be provided with the second shoulder 142 or the lower surface of the second side wall 14 may be provided with the second shoulder 142. In the first, third, and fourth embodiments, the upper and lower surfaces of the second sidewall 14 are provided with the second shoulder 142 at the same time.

Preferably, the first shoulder 132 and the second shoulder 142 are respectively provided on the first sidewall 13 and the second sidewall 14, and the first shoulder 132 and the second shoulder 142 are preferably symmetrically provided with respect to a center line between the first sidewall 13 and the second side, so that a position where the sidewall 1 contacts with the outer surface of the connector 5 can be increased, a depth of the sidewall 1 inserted into the conductive hole 51 can be better limited, and simultaneously, the sidewall 1 can be prevented from being inserted out of place by observing whether the first shoulder 132 and the second shoulder 142 contact with the outer surface of the connector 5, thereby facilitating the operation and inspection of personnel.

While embodiments of the present invention have been shown and described, it will be understood that the above embodiments are illustrative and not to be construed as limiting the invention, and that changes, modifications, substitutions and alterations may be made therein by those of ordinary skill in the art without departing from the spirit and scope of the invention, all such changes being within the scope of the appended claims.
