To sum up, the utility model discloses electric connector 100 has following beneficial effect:

(1) when assembling the electrical connector 100, the insulation body 3 may be first turned over, so that the terminal 2 is easily assembled into the receiving hole 31 from the bottom surface of the insulation body 3, the two first limiting portions 311 support the guiding portion 21 from two sides of the guiding portion 21, the second limiting portion 312 supports the elastic arm 26, the receiving hole 31 forms three-point stable limiting on the terminal 2, so that the terminal 2 cannot fall out from the receiving hole 31, and then the substrate 1 is fixed to the bottom surface of the insulation body 3, so as to complete the assembly of the electrical connector 100, so that the terminal 2 is easily assembled with the insulation body 3 and the substrate 1; the two first and second position-limiting

portions

311 and 312 are only used for limiting the position of the terminal 2, and when the first electronic component 4 is pressed against the contact portion 24, the guide portion 21 has a space for deforming the first position-limiting portion 311 and a space for deforming the elastic arm 26 with the second position-limiting portion 312, and the receiving hole 31 is not in interference fit with the terminal 2, so that the terminal 2 does not have a great influence on the insulating body 3 when elastically deformed by being pressed, and the insulating body 3 has high strength and is not easily warped and deformed.

(2) The insulating body 3 has the anti-collision area 33, and when the first electronic component 4 presses the contact portion 24 excessively, the contact portion 24 enters the anti-collision area 33 due to excessive displacement, so that the contact portion 24 is prevented from colliding with the insulating body 3 and damaging the contact portion 24.

(4) The base plate 1 is provided with the support member 6, the support member 6 supports the elastic arm 26, and the support member 6 supports the elastic arm 26, so that the terminal 2 can be supported by the metal member 5 and the support member 6 together to be in a balanced state even if the terminal 2 is not fixed, and the terminal 2 is not easy to topple or tilt.

(5) Since the supporting member 6 only supports the elastic arm 26 without being fixed to the supporting member 6, when the first electronic component 4 is pressed against the contact portion 24, the elastic arm 26 can be deformed to separate from the supporting member 6, so as to form a gap 25 between the elastic arm 26 and the supporting member 6, the elastic arm 26 can be freely and elastically deformed without being limited by the supporting member 6, and the length of the elastic deformation structure of the terminal 2 can extend from the contact portion 24 to the guide portion 21, so that the elastic arm 26 is more flexible and less prone to fatigue, and is easily restored to the original uncompressed position.

(6) The contact points 213 are disposed at one end of the conductive portion 21, when the first electronic component 4 is pressed against the terminal 2 and the conductive portion 21 is not soldered to the metal piece 5, the contact points 213 contact the metal piece 5, so that the conductive portion 21 and the metal piece 5 are electrically connected more frequently, and when one of the contact points 213 is lifted by a contaminant on the surface of the metal piece 5 and cannot be in good contact with the metal piece 5, the rest of the contact points 213 will be depressed relatively and electrically connected to the metal piece 5.

(7) The first metal plate 7 electrically connects the plurality of ground terminals 2a together without electrically connecting the signal terminals 2b, thereby forming a parallel effect of the ground terminals 2a and reducing the ground inductance; and the second metal plate 8 supports the insulation body 3, so that the position of the bottom surface of the insulation body 3, which is not provided with the first metal plate 7, is at the same height as the first metal plate 7, and the insulation body 3 has good coplanarity.

(8) A plurality of the fixing members 9 penetrate through the insulation body 3 and are fixed on the first metal plate 7 and the second metal plate 8, so that the insulation body 3 can be prevented from being separated and falling out, and because the fixing members 9 are made of a metal plate, the fixing members 9 are arranged around the insulation body 3 and can conduct heat generated by the electric connector 100 during working, so that the heat dissipation of the electric connector 100 is faster.

The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all the equivalent technical changes using the description and drawings of the present invention are included in the scope of the present invention.
