[0035] like figure 1 (A) to figure 1 As shown in (E), the electrical connector 1 has a bracket 3 , contact terminals 10 , terminals 20 for grounding, and a housing 6 . The electrical connector 1 is installed by abutting the bottom surface of the electrical connector 1 on a circuit board (not shown). The contact terminal 10 and the terminal 20 for grounding pass through the front and back direction of the bracket 3 ( figure 1 (E) in the left-right direction), and mounted on the bracket 3. The case 6 is a plate-shaped metal plate, which is bent into a cylindrical shape so as to cover the side surface of the bracket 3 .
[0036] like figure 1 As shown in (B), the contact terminal 10 and the ground terminal 20 protruding toward the back side of the frame 3 are bent, wound around the bottom surface of the frame 3, and connected to conductive pads (not shown) on the circuit board.
[0037] bracket 3 as figure 2 As shown, there are: a rectangular parallelepiped body part 3...

[0057] Next, a second embodiment of the present invention will be described with reference to the drawings. Since the electrical connector according to this embodiment differs from the above-mentioned first embodiment only in the connection relationship between the semiconductor element and the contact terminal, the description of the same structures as those in the first embodiment with the same symbols will be omitted. like Figure 4 (B) and Figure 5 As shown in (B), in the electrical connector according to this embodiment, any one of the contact terminals 11 to 15 is used for grounding, and the grounding contact terminals are used instead of the grounding terminals 20 and 20 . Specifically, when the contact terminal 15 is used for grounding, the conductive pads 30 a to 30 d and the conductive pad 30 e are connected through the overvoltage protection elements 51 to 54 inside the semiconductor element 30 .
[0058] In this way, using the grounding terminals connected to th...

[0060] Next, a third embodiment of the present invention will be described with reference to the drawings. The electrical connector according to this embodiment differs from the above-mentioned first embodiment only in the connection relationship between the semiconductor element and the contact terminal, so the description of the same structure as the first embodiment with the same symbols is omitted. like Figure 4 (C) and Figure 5 As shown in (C), in the electrical connector according to this embodiment, at least one pair of contact terminals 10 is divided into a first contact terminal and a second contact terminal, and are connected within the semiconductor element 30 through a desired circuit. Specifically, for the purpose of reducing common mode noise between the contact terminal 13 and the contact terminal 14 , first, the first contact terminal 13 a and the conductive pad 30 c are connected by the bonding wire 40 . In addition, the first contact terminal 14 a and the...
