[Prior Art] Referring to Figures 1 and 2, there is shown a conventional board-to-board connector for electrically connecting a first circuit board 21 and a second circuit board 22, and including a male unit. Π and a female unit 12. The male unit 11 includes an insulating male seat disposed on the first circuit board 21 and a plurality of conductive terminals 112 electrically connected to the first circuit board 21. The terminals 112 are inserted in the male seat in a substantially parallel and spaced apart manner, and one end projects out of the male seat 111. The base unit 12 includes an insulating base 121 disposed on the second circuit board 22, and a plurality of conductive spring assemblies 122 electrically connected to the second circuit board 22, respectively. The mating surface 121 has a bonding surface 123 disposed on the second circuit board 22, an open surface 124 spaced apart from the bonding surface 123, and a body connecting the bonding surface 123 and the opening surface 124. 125, and a plurality of pockets 126. The equal-receiving slots 126 are spaced apart from each other and formed on the open surface 124, and extend along a first direction substantially perpendicular to the second circuit board 22 to the bonding surface 123. The mother-grooves 126 are provided for the corresponding terminals ip and The shrapnel assembly 122 is received, and the shrapnel assembly 122 is embedded in the body 125. Each of the shrapnel assemblies 122 has two opposing elastic pieces 127, each of which has a support portion 128 that is flat against the body 125, and a projection 129. The protrusion 129 has a first end 1310618 130 connecting the support portion 128 and a second end 131 opposite to the first end 130. The board-to-board connector 1 has two connection types. The first connection type is that the second circuit board 22 and the male seat 111 are located between the first circuit board 21 and the female seat 121, and the second type The end 131 is clamped to the corresponding terminal 112, and the first and second circuit boards 21, 22 have a first spacing d1. Referring to FIG. 1 and FIG. 2, the second connection type is that the male and female seats iu and 121 are located between the first and second circuit boards 21 and 22. When the terminals 112 are inserted, they will abut the second ends. 131. The connection type is such that a second spacing d2 of the first and second circuit boards 21, 22 is greater than the first spacing dl. However, in the second connection type, the terminals 112 are not easy to penetrate, and the springs 127 are easily damaged, which is not practical. Referring to FIG. 2 and FIG. 3 'If there is a capacitor 23 or other components (not shown) having a thickness greater than that of the male seat, when disposed on the first circuit board 21, in practice, only the second connection described above can be used. The type (d2>d) is completely accommodated by the capacitor 23 or other components and is not pressed by the second circuit board 22. However, the second connection type described above has the aforementioned disadvantages and cannot be used. Although the board-to-board connector 电 can electrically connect the first circuit board 21 and the second circuit board 22, there are still the following defects: 1. The main deformation force point of the protruding portion 129 is only the first end. 13〇, so the elastic piece 127 is easily elastically fatigued or broken when used for a long time, resulting in a loss of a lower service life. 1. In the second connection type, the terminals 112 are not easy to penetrate, and the elastic pieces 127 are easily damaged. Therefore, the board-to-board connector 1 is only applicable to the first connection type, and is not suitable for the case where the large capacitance 23 is provided on the first electric 1310618 board 21, thereby causing a missing connection type.

The equal-receiving slots are formed on the open surface at intervals, and extend along a first direction substantially perpendicular to the second circuit board to the bonding surface, and each of the corresponding slots is provided with the corresponding terminal and the spring assembly. The shrapnel assembly is hosted in the body. Each of the shrapnel assemblies has two opposing elastic pieces, each of the elastic pieces having a supporting section spaced apart from each other and lying on the body, and a reversed end connecting the protruding sections of the supporting segments respectively. The protruding section is spaced apart from the body I in the pocket. Each of the terminals can be inserted between the protruding portions along the first direction and a second direction opposite to the second direction, and the protruding portions can be pressed to the terminal to compress and deform to match the terminal. . 7 1310618 to achieve an improved service life and the design of the bulging section is more flexible.
