Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to an electrical connector. [Prior Art] [0002] Board-to-board connectors are widely used in current electrical systems in which electrical components, such as central processing units or other components, are mounted on a printed circuit board and are The lines are connected, and the two printed circuit boards are connected by our familiar board-to-board electrical connectors. A conventionally known or typical board-to-board connector such as the mutual loose-fitting male and female connectors disclosed in U.S. Patent No. 5,639,248, the plurality of conductive terminals being arranged along the longitudinal direction of the connector, each of the conductive terminals The mating direction of the male and female connectors extends. As a connector improvement, male and female electrical connectors have also appeared, such as the connector disclosed in U.S. Patent No. 5, lgi, No. 985, which has a male-female structure, during the manufacturing process, A great advantage of the connector is that a male and female connector can be produced as long as a mold is developed, which is more suitable for mass production. However, the two types of connectors described above have a certain height. [0003] Further, U.S. Patent No. 5,557,574 discloses a male-female electrical connector. The conductive terminals of the electrical connector are of a horizontally extending configuration, and the mating direction of the terminals is parallel to the abutting faces. However, we can also find that the mating between the two connectors has no fixing force, and the screw and the bolt need to be used for the mating. The electrical connector is not suitable for the current miniaturization and convenient insertion and removal of the electrical connector. SUMMARY OF THE INVENTION [0004] In view of the above, it is an object of the present invention to provide a low profile and square 099121351 form number A0101 page 3 / total 13 page 0992037612-0 201201459 plug and play electrical connector. [0005] The object of the present invention is achieved by the following technical solutions: an electrical connector includes a base, a first terminal and a second terminal fixed to the base, the base has an abutting surface and a mounting surface; the first terminal is a metal piece, comprising a fixing portion and a resilient arm extending from the fixing portion, the elastic arm is provided with a contact point, the contact point forms a plugging direction perpendicular to the abutting surface; the second terminal is a columnar body, which comprises a vertical The contact portion of the butt joint. Compared with the prior art, the vertically arranged first and second terminals of the present invention not only make the electrical connector structure low, but also facilitate insertion and removal. [Embodiment] [0007] Referring to the first figure, the present invention introduces a male and female electrical connector 100a, 100b. The two electrical connectors are respectively mounted on a circuit board (not shown) and cooperate with each other. Complete the electrical connection between the two boards. Since the two electrical connectors are identical in construction, the same reference numerals are used and will not be separately described when the components are specifically described. Referring to the second and third figures, the electrical connector includes a rectangular insulative base 1 in the form of a plate having an upper surface which is an abutting surface 101 and a lower surface which is a mounting surface 102. Forming a shallow plurality of rectangular receiving grooves 11 from the butt-facing surface, the receiving grooves 11 are arranged in a first direction (ie, the longitudinal direction of the base), and each of the individual receiving grooves 11 is formed by four side walls. The longitudinal direction is a rectangular shape, and the extending direction thereof is a second direction perpendicular to the first direction. The bottom surface 110 of the receiving groove is located at a side of the side wall 111a in the second direction and protrudes perpendicularly to the abutting surface 101. The column 12 has a smaller size than the receiving groove, and neither side of the positioning column is in contact with the four side walls of the receiving groove. A fixing hole penetrating through the abutting surface 101 and the mounting surface 102 is provided in the middle of the positioning column 12. 099121351 Form No. A0101 Page 4 of 13 0992037612-0 201201459 121. The side wall 1113 is provided with a notch 112 extending through the abutting surface and the mounting surface. The bottom surface 11 is provided with a receiving hole 113 penetrating the mounting surface on the other side of the opposite positioning post. The upper surface of the positioning post is located on the same plane as the mating surface 1〇1 (the fourth figure is clearly visible). Of course, the positioning post can be shorter, so that the positioning post does not protrude from the mating surface 1 〇丨. [0011] [0011] The first terminal 2 is formed by stamping and bending a metal sheet, and includes a frame-shaped holding portion 21'. The through hole 211 is provided in the middle of the holding portion 21, and the outer side is provided with a spur. 212. A pair of elastic arms 22 extend from one side of the retaining portion, and the ends of the two resilient arms are provided with facing curved projections to form contact points 221. The opposite side of the retaining portion extends from the land portion 23 which is first deflected to the re-level. The first terminal 2 is vertically mounted into the receiving slot 丨1 from the mating surface 1 〇1, and the through hole 211 of the retaining portion is sleeved on the positioning post 12, and the ribs 212 on both sides of the retaining portion interfere with the two sides of the receiving slot. on. The first terminal: the solid portion 21 and the elastic portion 422 are in close contact with the bottom surface 11 of the receiving groove. The two contact points 221 are located on the upper side of the receiving hole 113. The soldering portion 23 extends through the notch 112 and extends out of the side wall of the base. The outer side. Forming a vertical abutting surface between the two contact points
