Therefore, the supporting portion 421 can provide a supporting force for the first contact portion 411, so as to increase the upward contact force of the first contact portion 411 to the second contact portion 711, so that the contact between the two is more stable, and elastic fatigue of the first contact portion 411 is avoided, and meanwhile, as a cutting knife is used for stamping the cut strip downwards during cutting the strip, the first contact portion 411 may be driven to bend downwards, and the supporting portion 421 can avoid the first contact portion 411 from bending downwards and deforming due to the cutting action force during cutting the strip, so as to reduce the rejection rate of the first signal terminal 41; further, decide face 41171 outstanding in first side surface 4211 avoids first side surface 4211 has hindered the cutting to the material area, reduces the degree of difficulty of cutting the material area.

In the utility model, when the second injection molding part 424 is molded, the first signal terminal 41 is not required to be clamped by a mold, but the first signal terminal is clamped on the fixing part of the first injection molding part 423, after the first insulating block 42 is completely molded, the first connecting part 412 can be completely coated in an insulating material, and the media around the first connecting part 412 are the same, which is beneficial to the impedance consistency of the first connecting part 412. In this embodiment, the first supporting portion 421 is disposed on the second injection-molded part 424, and the first main body portion 425 of the first insulating block 42 includes the first injection-molded part 423 and a part of the second injection-molded part 424; in other embodiments, the first insulating block 42 may also be made of an insulating material by injection molding once or more than three times.

Therefore, a certain yielding space can be provided for the second contact part 711 by the first bending section 4113, the probability of collision when the first contact part 411 and the second contact part 711 are butted is reduced, and the first bending section 4113 can prevent the second contact part 711 from continuously sliding excessively towards the first connecting section 4112 to a certain extent; meanwhile, the supporting portion 421 can support the first bending section 4113, so as to prevent the first bending section 4113 from being damaged due to excessive bending deformation after the second contact portion 711 presses the proximal contact position 41141. Further, the width of the supporting portion 421 along the left-right direction Y is smaller than the width of the first bending section 4113 along the left-right direction Y, as shown in fig. 13, the width of the supporting portion 421 along the left-right direction Y is defined as a first width W1, the width of the first bending section 4113 along the left-right direction Y is defined as a second width W2, and the first width W1 is smaller than the second width W2. Therefore, the impedance of the first bending section 4113 is relatively high due to the bending shape thereof, and the first width W1 is smaller than the second width W2, so that the lower surface of the first bending section 4113 is more exposed to air, the impedance of the first bending section 4113 is reduced, and the impedance consistency of the first contact portion 411 can be adjusted.

It should be noted that in this embodiment, one of the first insulating blocks 42 has two limiting portions 422 to abut against the upper surfaces of the two first contact portions 411, but in other embodiments, the number of the limiting portions 422 included in one of the first insulating blocks 42 may be one or more than two, and is not limited herein. Therefore, the limiting portion 422 can prevent the first contact portion 411 from being damaged due to upward excessive tilting, and meanwhile, the projection of the limiting portion 422 and the projection of the corresponding support portion 421 are overlapped, so that the acting force exerted by the limiting portion 422 and the support portion 421 on the first contact portion 411 in the vertical direction Z can be relatively concentrated and aligned instead of being dispersed from left to right, the torsion of the first contact portion 411 due to the fact that the acting force exerted by the limiting portion 422 and the acting force exerted by the support portion 421 on the first contact portion 411 in the upward and leftward direction and the acting force exerted by the limiting portion 421 in the downward and rightward direction are respectively converted can be avoided, the torsion of the first contact portion 411 is avoided, and the butt joint of the first contact portion 411 and the second contact portion 711 can be ensured.

Therefore, since the restraining part 4251 connects the position-limiting part 422 and the supporting part 421, and the extending column 42511 is filled in the through hole 41121, the restraining part 4251 is firmly connected with the first contact part 411, and the restraining part 422 and the supporting part 421 are correspondingly attached to the first contact part 411, so that the abutting contact between the position-limiting part 422 and the supporting part 421 and the first contact part 411 is more stable; meanwhile, the extension column 42511 limits the first signal terminal 41 to move along the front-back direction X, so as to avoid that the connection of the first insulating block 42 between the first signal terminals 41 is loosened to cause the first contact portion 411 to move along the front-back direction X relative to the first insulating block 42, and ensure that the first contact portion 411 is located between the limiting portion 422 and the supporting portion 421.

Referring to fig. 12, an extension length of the limiting portion 422 along the front-back direction X is smaller than an extension length of the supporting portion 421 along the front-back direction X, and specifically, if the extension length of the limiting portion 422 along the front-back direction X is defined as a third distance L3, the third distance L3 is smaller than the second distance L2. Therefore, compared with the same extension length of the limiting portion 422 and the supporting portion 421, the utility model can allow the portion of the first contact portion 411 contacting the supporting portion 421 to be elastically deformed upwards, so as to avoid that only the portion of the first signal terminal 41 exceeding the supporting portion 421 can be elastically deformed upwards, and reduce the risk that the first contact portion 411 is bent upwards at the extension end 4212 of the supporting portion 421.

Therefore, as the cutting knife can be withdrawn upwards after cutting the material belt downwards, a certain friction force exists between the cutting knife and the cut surface 41171, and the friction force can drive the first contact part 411 to have an upward movement trend, the utility model can press the part connected with the material connecting part 4117 downwards along the left-right direction Y through the limiting part 422, so that the situation that the cut surface 41171 of the material connecting part 4117 rubs with the cutting knife to drive the first contact part 411 to bend upwards can be avoided, and the production rejection rate of the first signal terminal 41 is reduced; and decide face 41171 outwards outstanding second side surface 4221, be favorable to cutting the material area.

After the electrical connector 100 and the docking connector 200 are mated, each of the first signal terminals 41 is mated with a corresponding one of the second signal terminals 71, the second guiding connection portion 713 is soldered to the second substrate 10 by a solder ball 11 to improve the coplanarity of the plurality of second signal terminals 71, each of the first shielding cases 43 is mated with a corresponding one of the second shielding cases 73, each of the first shielding cases 43 is accommodated in a corresponding one of the second shielding cases 73, and the shielding structures of the electrical connector 100 and the docking connector 200 are communicated together, so as to improve the high-frequency performance and facilitate transmission of high-frequency signals.
