New Description: [New Technology Field] [0001] The present invention relates to an electrical connector, and more particularly to an electrical connector mounted on a circuit board for connecting a wafer module. [Prior Art] [0002] Chinese Utility Model Patent Publication No. 201352614 discloses an electrical connector including an insulative housing and a plurality of conductive terminals and solder balls housed in the insulative housing. The conductive terminal is provided with a plurality of terminal holes, and the conductive terminals and the solder balls are respectively assembled in the terminal holes. The solder ball is fixed by three planes of the conductive terminal and the inner wall of the terminal hole. The solder ball fixing method disclosed in this patent has a defect. Since the inner wall of the terminal hole has a large plane, the deformation to adapt to the size of the solder ball is weak, so the dimensional accuracy of the terminal hole and the solder ball is relatively high. If the terminal hole is large, the solder ball is difficult to be fixed and may be detached from the insulating body; if the solder ball is large, it may be impossible to fit into the terminal hole. [0003] Therefore, it is indeed necessary to improve existing electrical connectors to overcome the aforementioned drawbacks of the prior art. [New content] [0004] The technical problem solved by this creation is to provide an electrical connector for fixing a solder ball. [0005] In order to solve the foregoing technical problem, the present invention provides an electrical connector, comprising: an insulative housing comprising a top surface, a bottom surface opposite to the top surface, and a plurality of receiving holes penetrating the top surface and the bottom surface; and a plurality of conductive terminals for receiving And the plurality of solder balls are mounted on the bottom surface of the insulating body from the bottom surface of the insulating body, and the solder ball is placed in the receiving hole of the No. 1〇12〇633 production order No. A0101, page 3/19 pages 1012020954-0 M439920 The receiving hole is provided with an inner wall and a center of the receiving hole, and the inner wall of the receiving hole is provided with a protrusion protruding toward the receiving hole t, and the protruding rib is pressed against the solder ball The solder ball is fixed in the horizontal direction.

[Embodiment] The electrical connector of the present invention is usually soldered to a circuit board (not shown) for connecting a chip module (not shown). Referring to the first to third figures, the electrical connector 1 includes an insulative housing 2 and a plurality of conductive terminals 3 and solder balls 4 assembled in the insulative housing 2. The insulative housing 2 is provided with a receiving hole 20 for receiving the conductive terminal 3 and the solder ball 4, and the receiving hole 20 extends through the top surface 21 and the bottom surface 22 of the insulative housing. The conductive terminal 3 is mounted on the receiving surface 20 by the top surface 21 of the insulative housing 2, and the solder ball 4 is mounted from the bottom surface 22 of the insulative housing 2 into the receiving hole 20 for connecting the corresponding conductive terminal 3. [0010] Referring to the fourth to sixth figures, the conductive terminal 3 includes a base portion 30, a fixing portion 31 extending downward from the base portion 30, and a pair of contact portions 32 extending upwardly from the base portion 30 and laterally bent. The pair of contacts 32 are disposed toward each other and are in contact with electrical conductors (not shown) at the bottom of the wafer module. The base portion 30 interferes with the inner wall 200 of the receiving hole 20 and fixes the conductive terminal 3 in the receiving hole 20. [0011] The fixing portion 31 fixes the solder ball 4 together with the receiving hole 20. The receiving hole 20 is provided with an inner wall 200 and a receiving hole center (not labeled). The inner wall 200 of the receiving hole 20 includes a first side (not labeled) and a second side (not labeled) disposed opposite to each other, and connects the first side and the second side. The third side (not labeled) and the fourth side (not labeled) opposite the third side. The first side and the second side of the receiving hole 20 are respectively provided with a protruding rib 201 protruding toward the center of the receiving hole. The protruding rib 201 extends along the first side and the second side of the insulating body 2 to be pressed against the solder ball 4 The opposite sides of the solder ball 4 are respectively fixed in the horizontal direction. The pair of protruding ribs 201 are disposed opposite to each other. 101106331^单单号AQ1(H Page 5 of 191012020954-0 M439920 The fixing portion 31 of the electrical terminal 3 protrudes from the third side to be in contact with the solder ball 4. The inner wall 200 of the receiving hole 20 corresponds to the fourth The side position is "V" shaped to abut the solder ball 4, and the fourth side of the inner wall 200 having a "V" shape is perpendicular to the bottom surface 2 2 of the insulative housing 2. [0012] The two protruding ribs 201 correspond to the insulative housing 2 The bottom surface 22 is provided with a recess 220, and the recess 220 communicates with the adjacent receiving holes 20 in the horizontal direction. The presence of the recess 220 can enlarge the receiving hole 20 for the opening of the solder ball 4 to press, and ensure the pressing width of the solder ball 4, Thereby, the solder ball 4 can be fixed more reliably. [0013] Furthermore, the insulative housing 2 is provided with a support block 202 located below the contact portion 32 of the conductive terminal 3, and the support block 202 can be blocked when the contact portion 32 of the conductive terminal 3 is pressed. The contact portion 32 can prevent the contact portion 32 from being deformed by excessive pressing. The support block 202 is recessed from the top surface 21 of the insulating body 2 toward the bottom surface 22, and the top surface 21 of the insulating body 2 and the support block 202 are stepped. The inner wall 200 of the receiving hole 20 and the supporting block 202 are stepped [0014] When the electrical connector 1 is assembled, the conductive terminal 3 is first inserted into the receiving hole 20 from above the insulating body 2. Then, the solder ball 4 is pressed from the bottom of the insulating body 2 to the receiving hole 20 to a proper depth. The solder ball 4 is simultaneously fixed by the fixing portion 31 of the conductive terminal 3, the protruding rib 201 on the inner wall 200 of the receiving hole 20, and the fourth side of the "V"-shaped inner wall 200 opposed to the fixing portion 31. Since the protruding rib 201 is relatively volume-sensitive Smaller, so the ability to deform is adapted to the size of the welding ball 4, so that the effect of fixing the welding ball can be better. After the assembly is completed, the contact portion 32 of the conductive terminal 3 is located on the top surface 21 of the insulating body 2.
