[Prior Art] An electrical connector 丨00 (shown in the first figure and the second figure) of the prior art, electrically connected-connected electronic component 1000 to a circuit board (not shown), including an insulative body 1 The insulative housing 10 is provided with a plurality of terminal receiving holes n, wherein each of the terminal receiving holes 11 is provided with a first conductive terminal 2 and a second conductive terminal 30. The first conductive terminal 30' is provided with two pressing portions 21 and two opposing abutting arms 22, and the second conductive terminals 3G have a base portion 3b and The two substantially parallel elastic arms 32 extend, each of which has a first contact portion 321 and a second contact portion 322, and the first contact portion 321 is elastic at the end of the elastic arm 32. Resisting the above-mentioned pressing portion 21, the second contact box is located at the bottom end of the elastic arm 32, and between the first connection 321 and the base portion 31, which is close to the base portion, and the The arm 22 is pressed against the second contact portion 322, and when an external force acts on the first 2 〇, the (4) Xie 2G Downward county, clear-conductive terminal 2〇 of the pressing portion 21 of the wire paste: the wheel contact portion 321 is obtained by the elastic arm 32 being compressed and expanded outward, and at the same time, the first conductive terminal 3 M381938 20 abutting arm 22 is elastically deformed by the pressure of the second contact portion 322, so that the abutting arm 22 and the first-contact portion 322 of the elastic arm 32 of the second conductive terminal 3 are in close contact with each other to form an electric Sexual connection, when the external force is removed, the elastic arm 32 uses the elastic force to return the first conductive terminal 2 to the initial position. The disadvantage is that the second contact portion 322 is located at the bottom end of the elastic arm 32 and is close to the base portion 31, so that the first contact portion 321 located at the end of the second conductive terminal 30 is The elastic deformation amount _ of the second contact portion 322 is very small, and the abutting arm 22 resists deformation when the first conductive terminal 2 〇 has a large compression stroke and generates a large load. The second contact portion 322 moves downward, so that the deformation of the abutting arm 22 is also small, so that the load that the abutting arm 22 can bear is small, and most of the load is caused by the second The resilient arm 32 of the conductive terminal 30 bears, whereby the resilient arm 32 produces a greater extent of outward expansion, and once the two resilient arms 32 expand to a certain extent, the load of the elastic $32 exceeds itself.

Therefore, even if the compression stroke of the first and second conductive terminals is increased, the first and second conductive terminals can bear the load caused by the larger compression stroke, thereby avoiding the The two elastic arms of one of the first and second conductive terminals are subjected to more stress than their own lodging strength, causing plastic deformation thereof and failing to reset, causing poor electrical connection between the conductive terminals and the mating electronic components. And so on. [Embodiment] Hereinafter, the present invention will be further described with reference to the accompanying drawings and specific embodiments. Referring to the third and fifth figures, the present invention is a first-to-connect electronic component side G and a second butting electronic component 3GG having a plurality of first contacts. In the area 2 (1), the second docking electronic read 30G has a twisting and turning area, the electrical connection hi includes an insulative housing 2, and a plurality of first conductive terminals 4 disposed in the insulative housing 2 And a plurality of second conductive terminals 5 and a plurality of solders 6, one of the first conductive terminals 4 and one of the second conductive terminals 5 forming a conductive terminal group. Referring to the third, fifth, and sixth figures, the insulative housing 2 is provided with a plurality of receiving slots 21, and the receiving slots 21 extend through the upper surface 22, 23' of the insulative housing 2 adjacent to the receiving slots 21 Between the insulating spacers 213, a plurality of receiving holes 24 are recessed inwardly from the lower surface 23 of the insulating body 2, and each of the receiving holes 24 communicates with each of the receiving slots 21, and each of the The receiving body 24 is provided with a plurality of retaining holes (not shown) in each of the receiving slots 21 . Referring to the sixth figure, the receiving groove 21 is rectangular and arranged in a staggered manner. (Of course, in other embodiments, the receiving groove 21 may be arranged only in a vertical column or only in a horizontal row. Arranged, the rectangular opposite long sides 211 of the receiving slots 21 respectively face the opposite short sides 212 of the adjacent receiving slots 21, and the rectangular opposite short sides 212 of the receiving slots 21 respectively face adjacent receiving slots The arrangement of one of the relatively long sides 211' of 21 increases the width of the insulating spacers 213 between the adjacent receiving slots 21, thereby facilitating the uniform distribution of the stress of the insulating spacers 213 to ensure Mechanical strength, while avoiding too close spacing between the set of conductive terminals (including the first conductive terminal 4 and the second conductive terminal 5) located in the adjacent receiving slots 21 of the insulative housing 2 The adjacent conductive terminal groups are brought into contact with each other to form a short circuit phenomenon, and further, the arrangement of the conductive terminal groups per unit area is advantageous for the arrangement of the conductive terminal groups, and the utilization is fully utilized.

Referring to the third to fifth figures, each of the first conductive terminals 4 is a press-formable elastic sheet-like body, which is received in each of the receiving slots 21, and the first conductive terminal 4 is provided with - The first base portion 41' extends upward from the end of the first base portion 41 to the first abutting portion 42, and the opposite ends of the other end portion of the first base portion 41 are bent downward to extend the two first-elastic portions (10). The first butt joint protrudes from the upper surface 22 of the insulating body 2 and is electrically connected to the first contact region 201 of the first butt electronic component 200. The two first elastic arms 43 have a certain gap, and each of the first elastic arms M381938 43 has a connecting section 431, a terminal section 432 extending from the connecting section 431, and is connected by a bending section 433. The connecting section 431 and the end section 432. It is not difficult to understand. If the elastic deformation of the two first elastic arms 43 is to be increased, the gap between the two first elastic arms 43 can be increased, but at the end of the first elastic arm 43 When the gap is constant, the distance between the two connecting segments 431 is greater than the distance between the two end segments 432 by setting the bending section 433, so that the gap between the two end segments 432 is ensured. In the case of increasing the distance between the two connecting segments 431, the elastic deformation of the first elastic arm 43 is further increased. A contact portion 4321 and a guiding surface 4322 are disposed on the outer side of the end portion 432 (of course, a contact portion 4321 and a guiding surface 4322 may be disposed inside the end portion 432), and the guiding surface 4322 is provided. It extends to the contact portion 4321.

The second base portion 51 is opposite to the other end of the other end. The bend extends relative to the two second resilient arms. - the second docking ship of the second conductive terminal 5 does not protrude from the lower surface 23' of the rim body 2 and the second abutting portion 52 passes through the dip 6 disposed inside the accommodating hole and the first butt-connected electron The second contact region 3〇1 of the component 3 is electrically conductive (of course, in other embodiments, the second buttress 52 may also protrude from the lower surface 24 of the insulating body 2 and the second docking electronic component The second contact zone of the class tears the phase compression contact). - 8 kg, the first elastic arms 53 have a constant gap, and each of the second elastic arms has a contact surface 53. The contact surface 531 is away from the second base, and between the two contact surfaces 531 The gap is tapered toward the second base. In the embodiment, the contact surface 531 is disposed on the inner side of each end of the second elastic arm 53 and is slidably guided to the guiding surface. (Of course, in other embodiments, the contact surface 531) may be provided on the outer side of the end 54 of the second resilient arm 53. In addition, the second base portion 51 of the second conductive terminal 5 is provided with two latching portions 55'. The two latching portions 55 are divided into the two holes (not shown) to form a concave and convex clip. The structure ensures that the first conductive terminal 4 and the second conductive terminal 5 can be stabilized in the fixed-face slot 21 . Referring to the second to sixth figures, in the assembly, the first conductive terminal 4 is first installed in the receiving groove 21 from the lower surface 23 of the insulative housing 2 to make the first conductive The first abutting portion 42 of the terminal 4 protrudes from the upper surface 22 of the insulative housing 2.

(Of course, in other embodiments, the contact surface 531 of the second elastic arm can also be located between the sides of the first elastic arm 43), M381938, simultaneously ensuring the first elastic arm The gap between the outer sides of the contact portions 4321 of 43 is larger than the minimum gap between the contact faces 531 of the second elastic arms 53. Finally, the solder 6 is placed in the receiving hole 24 of the body 2 to be overlapped on the second abutting portion 52 of the second conductive terminal 5, thereby assembling the electrical connector. 1. Mounting the first butt electronic component 200 and the second docking electronic component 300 to the electrical connector 丨±, and heating the solder 6 to replace the electrical connector The two conductive terminals 5 are soldered to the plurality of second contact regions 3 () 1 of the second butt electronic component 3GG to electrically connect the electrical connector 1 and the second butt electronic component 3 (8).

Due to the arrangement of the guiding surface 4322, the first conductive terminal 4 is not required to be dusted, as the first conductive terminal 4 is downward. The stroke of the movement is increased, and then the contact portion of the first elastic arm 43 is slidably guided to the contact surface 531 of the second elastic arm 53, and the first elastic arm 43 is gradually approached during the downward movement. The second elastic arm 53 gradually expands and moves away, because the first conductive terminal 4 and the second conductive terminal 5 are apart from the second elastic arm 53 at the contact portion 4321 of the first elastic arm 43. The sliding contact is started at the contact surface 531 of the second base 51, so that the first elastic arm milk and the second elastic arm 53 each have a large deformation amount, so even if the M381938
