In the conventional cable connector described above, an LSI connector, a printed circuit board, and a cable connector are interposed in order to connect the LSI and the cable. However, there is a disadvantage that the transmission speed of the electric signal at the time becomes slow. Further, there is a disadvantage that it takes time to connect the LSI and the cable. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks, and to provide a cable connector in which the transmission speed of an electric signal between an LSI and a cable is made faster and connection is easier.

[0004]

In order to achieve the above object, a cable connector according to the present invention is a cable connector for connecting a cable to a printed circuit board for supplying an LSI and a power supply and a ground, wherein a conductor portion is provided on the inside. A first contact having an outer portion formed by an insulating portion; a plurality of second contacts having an outer portion formed by a conductor portion and an inner portion formed by an insulating portion; The insulating part outside the contact and the conductor part outside the second contact make contact with the through hole in the printed circuit board, and the conductor part inside the first contact and the insulating part inside the second contact Between LSI LSI
A pin is inserted, and the conductor inside the first contact and the insulating part inside the second contact are LS of the LSI.
I pin and the first contact is directly connected to the LS
The LSI pins of I, the second contact is configured to be electrically connected to the wall surface of the through hole of the printed circuit board, electrical to cables from LSI pins of the LSI

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a cable connector according to the present invention. The A connector 1 is connected to the cable 2. On the upper surface of the A connector 1, two A
The contacts 3 are planted at positions facing each other.
Similarly, two B contacts 4 are planted at positions facing each other. These two A contacts 3 and two B
The contacts 4 have a positional relationship of crossing each other,
When viewed from above, they are substantially annular. The A contact 3 has an insulating part 3b on the inside and a conductor part 3a on the outside. B contact 4 is opposite to A contact 3,
The inside is constituted by the conductor portion 4b, and the outside is constituted by the insulating portion 4a.

FIG. 2 is a sectional view showing a state before the LSI 10 and the cable 2 are connected. FIG. 3 is a cross-sectional view showing a state where the LSI 10 is mounted on the printed circuit board 7. The LSI pin 8 of the LSI 10 is inserted into the through hole 9 of the printed circuit board 7.
To mount the LSI 10 on the printed circuit board 7. In this mounted state, the LSI pins 8 of the LSI 10 do not contact the wall surfaces of the through holes 9 of the printed circuit board 7.
FIG. 4 is a sectional view showing a state where the LSI 10 and the cable 2 are connected. After mounting the LSI 10 on the printed circuit board 7, the contact portions each having a substantially annular cross section composed of the A contact 3 and the B contact 4 are respectively formed by the LSI of the LSI 10.
It is fitted between the pin 8 and the through hole 9 of the printed circuit board 7. A contact 3 and B contact 4 are each LS
It contacts the LSI pin 8 of I10 and the through hole 9 of the printed circuit board 7.

The inside of the A contact 3 is an insulating portion 3
b, since the outside is composed of the conductor portion 3a, the conduction is not made to the LSI pin 8 but to the through hole 9 of the printed circuit board 7. That is, it is possible to supply GND to the cable 2 from the printed circuit board 7. Since the outer side of the B contact 4 is constituted by the insulating portion 4a and the inner side is constituted by the conductor portion 4b, the B contact 4 is electrically connected to the LSI pin 8 and not to the through hole 9 of the printed circuit board 7. That is,
An electric signal can be transmitted to the cable 2 from the LSI pin 8 of the LSI 10. LSI 10 and cable 2
Can be connected only by the contact between the LSI pin 8 and the B contact 4, so that the transmission speed of the electric signal between the LSI 10 and the cable 2 can be increased. After the connection between the LSI 10 and the cable 2, only the LSI 10 can be replaced.

[0008]

As described above, since the present invention has a configuration in which the pins of the LSI and the contacts of the cable connector are directly connected, the transmission speed between the LSI and the cable can be increased as compared with the conventional case. In addition, there is an effect that connection can be easily performed without taking much time.
