New Description: [New Technology Field] This creation relates to an electrical connector terminal, and more particularly to an electrical connector terminal for electrically connecting a chip module to a printed circuit board. [Prior Art] LGA electrical connection is used to electrically connect a chip module to a printed circuit board, and one side of the chip module is provided with a conductor having a sheet structure, and the LGA electrical connector generally has a thin plate shape and is assembled An insulating body on the printed circuit board, the middle portion of the insulating body is a conductive region, and a plurality of electrical connector terminals are received in the conductive region, and the electrical connector terminal has better elasticity and partially protrudes from the outside of the insulating body, and the electrical connector When the terminal is connected to the chip module, the electrical connector terminal is elastically deformed by pressing the external force to elastically abut against the electrical conductor of the chip module, thereby achieving electrical connection between the chip module and the printed circuit board. As shown in the fourth figure, a conventional electrical connector terminal 9 includes a base portion 8, a retaining portion 10' extending downward from the base portion 8, and a tail portion 7 formed by horizontally bending the end of the retaining portion 10', and From the base 8, one side of the elastic sheet 6 is bent out. The first and second barbs 1〇1 and 1〇2 are respectively disposed on the two sides of the holding portion 10. The elastic piece 6 is bent upward to form an elastic portion, and the elastic portion is provided with a curved portion 60 and a contact portion 62. However, the first and second barbs 101, 102 are formed to protrude outward from the two sides of the holding portion 10, and are solid and fixed, and have high rigidity. In the process of assembling the electrical connector terminal to the insulative body of the electrical connector _ T, since the electrical connection n terminal is forcibly inserted into the insulating body towel, the insulating body is prone to generate a large insertion force to the terminal, thereby causing The electrical connector terminals are distorted and even break the insulating body, thereby affecting the guiding performance of the chip module and the printed circuit board. Therefore, it is necessary to design a new type of electrical connector terminal to overcome the above drawbacks. [New content] 5, M319539 has a resilient arm main barb. The main barb includes a resilient arm and a tip. - Compared with the prior art, the advantage of this creation is that the barb of the electrical connector terminal is in the elastic arm mode, the barb deformation is flashed when the inserted insulating body is subjected to the resistance, and the insertion resistance becomes small, thereby avoiding the electrical connection ^ terminal Distortion occurs when inserted; and the barb of the electrical connector terminal penetrates into the insulating body, so that the connector terminal has a high holding force and is not easy to exit. /λ [Embodiment] Please refer to the first and second figures. The terminal block of the original electrical connector can be used to electrically connect the chip module (not shown) to the printed circuit board (not shown), including The base portion 1 , the holding portion 11 extending downward from the base portion 1 , the tail portion 12 extending downward from the holding portion 11 , and the elastic piece elastic sheet 9 bent from one side of the base portion 10 include a connecting portion 91 , a support portion 92 extending in a vertical direction and an elastic portion 93 connected to one end of the support portion 92, wherein the elastic piece 9 is connected to one side of the base portion 10 via the connecting portion 91, and the connecting portion 91 has a bending to make the elastic portion An angle is formed between the sheet 9 and the base 1〇. The elastic portion 93 includes a first planar extending portion 931, a second planar extending portion 933, a bent connecting portion connecting the first and second planar extending portions 931, 933, and an arcuate contact portion 934 disposed at the end of the elastic portion 93. The retaining portion 11 is provided with a barb including a resilient arm main barb 12 〇 and a positioning small barb 123 , wherein the elastic arm main barb 12 〇 is substantially crescent shaped, and includes a resilient arm 121 and a tip 122 . The small barbs 123 are disposed on the same side of the main barbs 120, and opposite sides of the ends of the retaining portions 11 are provided with guide bevels 11 for guiding the electrical connector terminals 1 into the insulative housing 2. ® As shown in the third figure, the third figure is a schematic view of the electrical connector terminal 1 housed in the insulative housing 2. The insulative housing 2 has a substantially rectangular structure, and is provided with a plurality of substantially square terminal holes 3, and the electrical connector terminal 1 is slowly inserted into the terminal hole 3 under the guiding action of the guiding inclined surface 11〇, and is set by the electrical connector terminal 1 The main barb of the elastic arm mode is 12〇, so the resistance of the insulating body 2 applied to the terminal 1 of the electrical connector during the insertion process forces the elastic arm 121 of the main barb 12 to be deformed and flashed to reduce the insertion resistance. Therefore, the electrical connector terminal 1 is prevented from being inserted into the deformation; and when the electrical connector terminal 1 is withdrawn, the original deformed elastic arm 121 is restored to the original shape and the small barb 123 is positioned and penetrated into the insulative housing 2 to ensure the electrical connector. Terminal 1 has a high holding force. After the assembly is completed, the main barb 120 is substantially crescent-shaped, and a chip pocket 21 is recessed from the outer side of the elastic arm 121 to the retaining portion 11 6 M319539 to receive the chip generated by the electrical connector terminal 1 inserted into the insulating body 2; The elastic portion 93 and the tail portion 12 of the electrical connector terminal 1 respectively protrude from the upper and lower surfaces of the insulative housing 2 to be electrically connected to the chip module and the printed circuit board. ~ As needed, the main barbs and the positioning small barbs can be symmetrically arranged on both sides of the electric connector terminal holding portion. In addition, the positioning small barbs can also be arranged on the elastic bar of the main barb.
