SUMMARY OF THE INVENTION The present invention provides an electrical connector including an insulating substrate having a first and a second pair of surfaces. The insulating substrate has a plurality of second ports and a plurality of conductive resistors mounted to the plurality of first openings. Each of the conductive elastic terminals has first and second opposite ends, and the first and second opposite substrate surfaces are spaced apart from each other by the first and second insulating substrates, and the plurality of second openings are formed by the plurality of second openings A plurality of non-conductive blocks. Each non-conductive 1343156 electrical block has first and second opposite end surfaces, respectively, first and second, and a third and fourth distance from the surface of the substrate. The third distance is shorter than the first distance. The fourth distance is shorter than the second distance. Each of the foregoing non-conductive stops separates adjacent conductive elastic terminals. [Embodiment] A connector for forming a board-to-board or board-to-device electrical connection' and a method of manufacturing the connector have been disclosed. According to the first to fifth figures, the connector 10 comprises an insulating substrate 12, such as a polyimide film (for example Kapt〇nTM) and a plurality of conductive elastic column terminals 14 fixed in the aforementioned substrate 12, which will be discussed in detail below. The terminal assembly 16 formed by the substrate 12 and the conductive elastic columnar terminal 14 is formed. The aforementioned connector 1A includes an insulating support pillar W of a slightly rounded shape, which is adjacent to and surrounds the aforementioned columnar terminal 14. In addition, the connector 10 also has an insulating intermediate pillar 20. Each of the intermediate pillars 2 is disposed adjacent to the selected one or array of support pillars a. Each support post 18 supports a single conductive elastomeric post 14 and provides mechanical support for the individual terminals. An insulating bridge portion 22 extends between each of the intermediate pillars 20 and at least one of the adjacent support pillars 18 in the group of individually selected support pillars 18. The insulating bridge portion 22 is a by-product of the passage in the mold, and the liquid insulating material is ejected from the holes in the intermediate column 20 to form a by-product produced by the support crucible 18. The injected insulating material flows through the passage, and then flows into the mold of the intermediate pillar 20, the supporting weir 18 and the bridge portion 22, and then, after the insulating material is hardened, it is left in the original passage position to form a bridge portion. . The aforementioned columnar terminals 14 are held in the aforementioned substrate 12' side by side 7 1343156 as a predetermined matrix and in one embodiment, the aforementioned support pillars 18, intermediate pillars 20 and bridges 22 are made of an insulating polymer ( Such as silicone rubber) is molded in one piece. The insulating substrate 12 includes a plurality of first and second holes respectively arranged in the first and second matrices. In addition to the holes in the edge of the matrix, each of the second holes is surrounded by a hole in the first hole matrix. The size of the aforementioned substrate can be adjusted according to the needs of individual applications. For example, holes for calibration can be placed on the substrate 12 outside the first and second holes. The terminal blocks 16 are formed by arranging the conductive elastic columnar terminals 14 in a predetermined matrix, so that the columnar terminals 14 can extend through the selected first holes and be fixed in the substrate 12. The above-mentioned conductive elastic columnar terminal 14 can also be manufactured by a process well known in the industry. In the disclosed embodiment, a portion of the columnar terminals 14 extending from the substrate 12 are columnar and have a maximum diameter adjacent the portion of the substrate 12. However, the columnar terminal 14 can also be in any suitable column shape. In the first step of molding, the substrate 12 is inserted into the first mold, and then the conductive elastic material is injected into the mold, and a plurality of integrally formed column terminals 14 are formed on both sides of the substrate 12. . The diameter of the portion of the columnar terminal 14 adjacent to the substrate 12 is the largest diameter and larger than the diameter of the hole through which the columnar terminal on the substrate 12 extends. Therefore, after the conductive elastic material is hardened and the columnar terminals 14 are formed, the columnar terminals 14 extend outward from both side edges of the substrate 12 and are fixed in the substrate 12. The plurality of first holes on the substrate 12 may be arranged in a pattern of a first predetermined grid and the columnar terminals 14 are molded. Thus, the terminal assembly 16 having the columnar terminals 14 may be formed, and the columnar shape is formed. The terminal 14 is fixed in the substrate of the first 8 1343156 according to the first predetermined grid. In the second step of molding, the insulating support pillar 18 and the insulating intermediate weir 2 joined by the insulating bridge portion 22 can be formed into an integrally formed structure. The terminal assembly 16 is calibrated and adjusted in the mold, and then the insulating polymer is injected into the mold from the position of the intermediate pillar 2〇 so that the support pillar 18, the intertwining member 2〇 and the bridge portion 22 are Form an integrally formed structure. The intermediate ridge 2 延伸 extends through the first hole selected in the substrate 12. As mentioned above, the support pillar 18 generally has a cylindrical outer surface and is adjacent to and surrounds the individual columnar terminals 14. In the above embodiment, in addition to the insulating bridging portion, the supporting weir 18 and the intermediate post 20 are independent columnar structures, although other cross-sectional structures may be fabricated. The opposite 'end surfaces& of the aforementioned columnar terminals 14 are slightly higher than the end surfaces 26 of the individual column pillars 18. The aforementioned column pillars 18 are used to support the columnar terminals 14 of the building. When the connector is mounted between two printed circuit boards' or between a printed circuit board and a BGA or LGA device and subjected to axial compressive forces, the pillars 18 are selected to avoid deformation of the terminals. In order to further avoid deformation of the terminal 14, the intermediate column 20 is additionally provided between the support column 18 and the corresponding columnar terminal 14. The opposite ends of the intermediate post 20 are generally flat and act as a stop against excessive axial compressive forces applied to the post 14 and the support post 18 to avoid deformation of the connector. According to an embodiment, at least a portion of the outer surface of each of the intermediate pillars 20 is equidistant from the outer surface of the adjacent support weirs 18. The number of intermediate pillars 20 can be adjusted' and it can also be interspersed in a matrix of support pillars 18 〇 9 1343156.
