In the prior art, in order to reduce the resistance of the press-in terminal when the press-in terminal is inserted into the conductive hole, so that the press-in terminal is inserted into the conductive hole more smoothly, gaps are formed at the tail ends of two side arms of the press-in terminal generally, so that the structural strength of the tail ends of the two side arms is reduced, and the press-in terminal with low material thickness resistance is particularly beneficial to greatly reducing the resistance of the press-in terminal inserted into the conductive hole.

Referring to fig. 1 to 13, the present invention provides a press-in terminal 100 and an electrical connection assembly, wherein the press-in terminal 100 includes a side wall 1 and a holding portion 2, and the side wall 1 is connected with the holding portion 2. The electrical connection assembly comprises a press-in terminal 100 and a connecting piece (not shown), wherein the connecting piece is provided with a conductive hole (not shown) for the press-in terminal 100 to be inserted into, the press-in terminal 100 can be inserted into the conductive hole of the connecting piece, at least part of the side wall 1 of the press-in terminal 100 is abutted against the hole wall (not shown) of the conductive hole to realize connection with the connecting piece, and the conductive hole is a conductive hole of a circuit board or a plastic base, for example, and can be in a round hole shape. The connecting piece can be a Printed Circuit Board (PCB) or a base body with a plastic structure.

The side wall 1 includes a first side wall 11 and a second side wall 12 extending in an insertion direction, the insertion direction being a length direction of the press-in terminal 100, the first side wall 11 having opposite first and second ends 111 and 112, and the second side wall 12 having opposite third and fourth ends 121 and 122. The first end 111 of the first sidewall 11 and the third end 121 of the second sidewall 12 are connected to the holding portion 2. The second end 112 of the first side wall 11 and the fourth end 122 of the second side wall 12 are free ends, i.e. the second end 112 of the first side wall 11 and the fourth end 122 of the second side wall 12 are inserted as insertion ends, the second end 112 of the first side wall 11 and the fourth end 122 of the second side wall 12 are facing the connection piece and are inserted into the conductive holes. The side wall 1 is preferably made of a metal material, especially an elastic metal material, so that a certain supporting force can be ensured between the side wall 1 and the wall of the conductive hole, so that the side wall 1 can be stably connected with the wall of the conductive hole, and meanwhile, the side wall 1 made of the metal material also has conductivity, namely, an electric signal can be transmitted between the side wall 1 and the connecting piece.

The first end 111 of the first sidewall 11 and the third end 121 of the second sidewall 12 are respectively disposed obliquely inward such that the first end 111 of the first sidewall 11 and the third end 121 of the second sidewall 12 are connected to each other or are combined at the same end of the sidewall 1. The second end 112 of the first side wall 11 and the fourth end 122 of the second side wall 12 are respectively disposed obliquely inward, so that the second end 112 of the first side wall 11 and the fourth end 122 of the second side wall 12 may be triangular integrally, so as to guide the press-in terminal 100 to be smoothly inserted into the conductive hole.

The middle position of the first side wall 11 and the middle position of the second side wall 12 are respectively arranged in an outward protruding mode, namely, the whole of the first side wall 11 and the whole of the second side wall 12 can be arc-shaped, and an arc-shaped opening 16 is formed between the first side wall 11 and the second side wall 12, so that the supporting force between the first side wall 11 and the second side wall 12 and the conductive hole can be enhanced, and the connection between the first side wall 11 and the second side wall 12 and the conductive hole is more stable. An arc-shaped notch 17 communicating with the arc-shaped opening 16 is formed near the first end 111 of the first side wall 11 and the third end 121 of the second side wall 12, and the arc-shaped notch 17 can reduce the structural strength of the first side wall 11 at the first end 111 of the first side wall 11 and the third end 121 of the second side wall 12, i.e. the arc-shaped notch 17 can increase the elastic deformation force of the first side wall 11 and the second side wall 12, reduce the resistance of the side wall 1 to be inserted into the conductive hole, and enable the side wall 1 to be inserted into the conductive hole more easily.

An abutment 18 may be further formed between the arcuate opening 16 and the arcuate recess 17, and the abutment 18 may include a first abutment 181 disposed on the first sidewall 11 and a second abutment 182 disposed on the second sidewall 12. The shapes of the first abutting portion 181 and the second abutting portion 182 are preferably the same, and the first abutting portion 181 and the second abutting portion 182 may be arc-shaped, circular-shaped, triangular-shaped, or the like, and in this embodiment, the first abutting portion 181 and the second abutting portion 182 are arc-shaped and extend along the thickness direction of the first side wall 11 and the second side wall 12. The first supporting portion 181 protrudes toward the second side wall 12, and the second supporting portion 182 protrudes toward the first side wall 11, that is, the first supporting portion 181 and the second supporting portion 182 are disposed opposite to each other, and the first supporting portion 181 and the second supporting portion 182 are preferably disposed symmetrically with respect to a center line between the first side wall 11 and the second side wall 12.

After the first sidewall 11 and the second sidewall 12 are inserted into the conductive member Kong Bingfa to deform, the first abutting portion 181 and the second abutting portion 182 abut against each other to limit the deformation of the first sidewall 11 and the second sidewall 12. So can reduce the deformation of first lateral wall 11 and second lateral wall 12 after inserting in place or restrict its further deformation, prevent that first lateral wall 11 and second lateral wall 12 from deforming too greatly, first lateral wall 11 and second lateral wall 12 excessively deform, and then improved the holding power of first lateral wall 11 and second lateral wall 12, improved the holding power between first lateral wall 11 and second lateral wall 12 and the conductive aperture to promoted the uniformity and the stability of first lateral wall 11 and second lateral wall 12 and conductive aperture cooperation. The number of the first abutting portions 181 may be one or more, the number of the second abutting portions 182 may be one or more, and in this embodiment, the number of the first abutting portions 181 and the second abutting portions 182 are one.

The first gap 13 is formed between the second end 112 of the first side wall 11 and the fourth end 122 of the second side wall 12, the first gap 13 separates the second end 112 of the first side wall 11 and the fourth end 122 of the second side wall 12 from each other, and the first gap 13 can reduce the structural strength of the second end 112 of the first side wall 11 and the fourth end 122 of the second side wall 12, so that the resistance when the press-in terminal 100 is inserted into the conductive hole can be reduced, and the press-in terminal 100 can be smoothly inserted into the conductive hole. Particularly, when the sidewall 1 is made of a thicker material, the thicker sidewall 1 can reduce the impedance of the press-in terminal 100, and can ensure the overall structural strength of the press-in terminal 100. By providing the first gap 13, on the one hand, the resistance when the press-in terminal 100 is inserted into the conductive hole can be reduced, and the press-in terminal 100 can be smoothly inserted into the conductive hole, and on the other hand, the requirement of the impedance of the press-in terminal 100 can be satisfied, and the overall structural strength of the press-in terminal 100 can be ensured.

The second end 112 of the first sidewall 11 is provided with a first abutting portion 113, and the fourth end 122 of the second sidewall 12 is provided with a second abutting portion 123. After the first sidewall 11 and the second sidewall 12 are inserted into the conductive structure Kong Bingfa to deform, the first abutting portion 113 and the second abutting portion 123 may abut against each other to limit the deformation of the first sidewall 11 and the second sidewall 12, which is equivalent to the connection between the second end 112 of the first sidewall 11 and the fourth end 122 of the second sidewall 12, and the deformation of the first sidewall 11 and the second sidewall 12 may be equivalent, that is, the first sidewall 11 and the second sidewall 12 may deform synchronously. So can reduce the deformation of first lateral wall 11 and second lateral wall 12 after inserting in place or restrict its further deformation, and then improved the holding power of first lateral wall 11 and second lateral wall 12, improved the holding power between first lateral wall 11 and second lateral wall 12 and the conductive aperture to the uniformity and the stability of first lateral wall 11 and second lateral wall 12 and conductive aperture cooperation have been promoted.

Referring to fig. 1 to 4, in the first embodiment, the first abutting portion 113 includes a first step portion 1131 and a first notch 1132, and the second abutting portion 123 includes a second step portion 1231 staggered with the first step portion 1131 and a second notch 1232 staggered with the first notch 1132. The thickness of the first step 1131 is smaller than that of the other positions of the first sidewall 11, the thickness difference between the first step 1131 and the other positions of the first sidewall 11 may form a first notch 1132, the thickness of the second step 1231 is smaller than that of the other positions of the second sidewall 12, and the thickness difference between the second step 1231 and the other positions of the second sidewall 12 may form a second notch 1232.

The first step portion 1131 may be inserted into the second notch 1232, and the second step portion 1231 may be inserted into the first notch 1132 such that the first step portion 1131 and the second step portion 1231 overlap each other in the thickness direction of the press-in terminal 100, i.e., in the up-down direction in fig. 3, that is, the first step portion 1131 and the second step portion 1231 are staggered in the up-down direction, i.e., in the thickness direction perpendicular to the insertion direction, such that the first step portion 1131 and the second step portion 1231 abut each other in the up-down direction, i.e., in the thickness direction perpendicular to the insertion direction, to prevent the first step portion 1131 and the second step portion 1231 from being misaligned in the up-down direction, and further to prevent the first side wall 11 and the second side wall 12 from being deformed by moving or twisting the misalignment in the up-down direction, so as to keep the structure of the first side wall 11 and the second side wall 12 stable.

In particular, when the first and second sidewalls 11 and 12 are inserted into the conductive holes, the first and second sidewalls 11 and 12 can be prevented from being dislocated in the up-down direction, and not only can the first and second sidewalls 11 and 12 be stably connected to the conductive holes be maintained, but also the first and second sidewalls 11 and 12 can be prevented from being relatively moved or twisted in the up-down direction to damage the conductive holes.

In the insertion direction, the first step 1131 may abut against the second side wall 12, and the second step 1231 may abut against the first side wall 11. When the first and second sidewalls 11 and 12 are inserted into the conductive hole, the fourth end 122 of the second sidewall 12 abuts against the first stepped portion 1131, so the first stepped portion 1131 can limit deformation of the second sidewall 12 in the insertion direction, the second end 112 of the first sidewall 11 abuts against the second stepped portion 1231, so the second stepped portion 1231 can limit deformation of the first sidewall 11 in the insertion direction, that is, deformation of the first and second sidewalls 11 and 12 can be restrained to each other, so that excessive deformation of the first and second sidewalls 11 and 12 in the insertion direction is prevented, and further, holding force of the first and second sidewalls 11 and 12 in a transverse direction perpendicular to the insertion direction is enhanced, and abutting force between the first and second sidewalls 11 and 12 and the conductive hole is further improved, so that consistency and stability of fitting of the first and second sidewalls 11 and 12 with the conductive hole are improved.

The number of the first step 1131 and the second step 1232 is the same and may be one or more, and the number of the first step 1132 and the second step 1231 is the same and may be one or more, and in this embodiment, the number of the first step 1131, the first step 1132, the second step 1231 and the second step 1232 is one.

Preferably, the first step 1131 and the fourth end 122 of the second sidewall 12 have a second gap 14 in the insertion direction, and the second gap 14 is used to provide a deformation space for the second sidewall 12 in the insertion direction. Therefore, the second side wall 12 has a certain deformation space in the insertion direction, namely, the second side wall 12 is easier to deform, the resistance of the second side wall 12 to the insertion of the conductive holes is reduced, and the second side wall 12 is easier to insert into the conductive holes.

The second step 1231 has a third gap 15 with the second end 112 of the first sidewall 11 in the insertion direction, and the third gap 15 is used to provide a deformation space for the first sidewall 11 in the insertion direction. In this way, the first side wall 11 has a certain deformation space in the insertion direction, that is, the first side wall 11 is easier to deform, so that the resistance of the first side wall 11 to be inserted into the conductive hole is reduced, and the first side wall 11 is easier to be inserted into the conductive hole.

Further, in a direction perpendicular to the insertion direction, i.e., in the width direction of the press-in terminal 100, the outer side of the first step 1131 preferably contracts within the second notch 1232, i.e., the outer side of the first step 1131 contracts to the outer edge of the second sidewall 12, so that when the first sidewall 11 is inserted into the conductive hole, the first step 1131 is prevented from protruding from the outer edge of the second sidewall 12, and the first step 1131 is prevented from damaging the hole wall of the conductive hole.

The outer side of the second step part 1231 preferably contracts in the first notch 1132 in a direction perpendicular to the insertion direction, i.e., in the width direction of the press-in terminal 100, i.e., the outer side of the second step part 1231 contracts in the outer edge of the first side wall 11, so that when the second side wall 12 is inserted into the conductive hole, the second step part 1231 can be prevented from protruding out of the outer edge of the first side wall 11, and the second step part 1231 can be prevented from damaging the wall of the conductive hole.

Referring to fig. 5 to 6, in the second embodiment, the first side wall 11 and the second side wall 12 each include an inner side surface and an outer side surface that are disposed opposite to each other, the first abutting portion 113 may include a first protrusion 1133 protruding from the inner side surface of the first side wall 11 toward the second side wall 12, and the second abutting portion 123 may include a second recess 1234 recessed from the inner side surface of the second side wall 12 and cooperating with the first protrusion 1133. The shape of the first bump 1133 and the shape of the second recess 1234 cooperate to allow interengagement between the first bump 1133 and the second recess 1234. The first bump 1133 and the second recess 1234 may extend in the thickness direction of the first and second sidewalls 11 and 12. When the first sidewall 11 and the second sidewall 12 are inserted into the conductive member Kong Bingfa and deformed, the first bump 1133 and the second recess 1234 are engaged with each other, i.e., the surface of the first bump 1133 and the surface of the second recess 1234 are in contact with each other and pressed against each other, so as to prevent the first sidewall 11 and the second sidewall 12 from being excessively deformed, thereby enhancing the retention force of the first sidewall 11 and the second sidewall 12, and the excessive deformation includes the longitudinal deformation of the first sidewall 11 and the second sidewall 12 along the insertion direction and the transverse deformation along the direction perpendicular to the insertion direction, so as to further improve the holding force and the stability of the cooperation between the first sidewall 11 and the second sidewall 12 and the conductive via, thereby improving the consistency and stability of the cooperation between the first sidewall 11 and the second sidewall 12 and the conductive via.

The number of the first bumps 1133 may be one or more, and the number of the second recesses 1234 may be one or more, and in this embodiment, the number of the first bumps 1133 and the number of the second recesses 1234 are the same and are all plural, and the shape of each first bump 1133 corresponds to the shape of each second recess 1234.

The first abutting portion 113 may also include a first recess 1134, and the second abutting portion 123 may also include a second protrusion 1233 that cooperates with the first recess 1134. The shape of the first recess 1134 and the shape of the second protrusion 1233 are matched to each other so that the first recess 1134 and the second protrusion 1233 can be engaged with each other. After the first sidewall 11 and the second sidewall 12 are inserted into the conductive member Kong Bingfa and deformed, the first recess 1134 and the second protrusion 1233 are engaged with each other, so as to prevent the first sidewall 11 and the second sidewall 12 from being excessively deformed, further enhance the retention force of the first sidewall 11 and the second sidewall 12, further enhance the holding force between the first sidewall 11 and the second sidewall 12 and the conductive hole, and further enhance the consistency and stability of the cooperation between the first sidewall 11 and the second sidewall 12 and the conductive hole.

The number of the first recesses 1134 may be one or more, and the number of the second protrusions 1233 may be one or more, and in this embodiment, the number of the first recesses 1134 and the number of the second protrusions 1233 are the same and are all plural, and the shape of each first recess 1134 corresponds to the shape of each second protrusion 1233.

Referring to fig. 7 to 8, in the third embodiment, the first abutting portion 113 may include the first step portion 1131, the first notch 1132 and the first bump 1133 at the same time, and the second abutting portion 123 may include the second step portion 1231 staggered with the first step portion 1131, the second notch 1232 staggered with the first notch 1132 and the second recess 1234 matched with the first bump 1133 at the same time.
