Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector intended to simplify the mounting method of coaxial cables used for interconnecting various parts of electronic computers, for example.

FIGS. 1 and 2 are mounting diagrams showing a conventional mounting state of a coaxial cable. In each figure, 1 motherboard, 2
Pad daughter board, 3 pad daughter board connector attached to motherboard, 4 pad daughter board connector.
Pin, 5-pin coaxial cable, 6-pin inner insulator of coaxial cable 5, T-pin outer conductor of coaxial cable 5, 8-pin outer conductor T
The insulated wire 9 is the internal conductor of the coaxial cable 5. FIG. 2 shows an example of a connector used for mounting the 10-pin type. The conventional method for mounting the coaxial cable 5 is to first remove the outer sheath and internal insulator 6 of the coaxial cable 5 using a special tool, and attach the insulated wire 8 to the external conductor 7 by a method such as soldering. A terminal processing operation is performed in which an insulating tube is placed over the part, and then the connection with the daughter board connector pin 4 is usually performed as shown in FIG. 1 or FIG. 2.

Figure 1: Inner conductor 9 of coaxial cable 5, if required.
and the center conductor of the insulated wire 8 are each soldered to the daughter board connector pin 4, and an insulating tube is placed over the soldered portion to maintain mutual insulation between the pins.

In the case shown in FIG. 2, after attaching contacts to the inner conductor 9 and the center conductor of the insulated wire 8, insert the contacts into the connector 10, and attach the connector 10 to the connector pin 4. .

According to the conventional mounting method as described above, it is impossible to avoid attaching the insulated wire 8 to the outer conductor 7 and the complicated processing involved in the terminal processing of the coaxial cable 5, which increases the manufacturing time. It is impossible to avoid a decrease in reliability due to an increase in costs and an increase in the amount of processing work.

In addition, although the signal that leads to the outer conductor T of each coaxial cable 5 is actually a common ground signal, it is possible to connect as many connectors as the number of outer conductors of the required coaxial cables.
Since pin 4 is required, this also hinders the improvement of packaging density. The present invention relates to a connector which eliminates the need for complicated terminal processing of coaxial cables as described above, provides a more reliable coupling method, and improves packaging density.

FIG. 4 is a front view of one embodiment of the connector according to the present invention as seen from the coaxial cable insertion side, and FIG. 5 is a cross-sectional perspective view taken along the line AA in FIG. 4.

In this embodiment, there are two first contacts and three second contacts, the first external contact of the first contact, the second external contact of the first contact, and the third external contact of the first contact. This shows a case where the second contacts of the two contacts are connected to each other and the other contacts are insulated from each other. 4 and 5, 12 is an insulating material, 13a is an internal contact of the first contact, 13

16 is a metal part that connects the external contact 13b of the first first contact and the external contact 14b of the second first contact, and 17 is the external contact 14b of the second first contact. This is a metal part that connects with the third second contact 15c.

FIG. 6 is a mounting diagram showing a mounting method when using the connector 11 according to the present invention.

In FIG. 6, a coaxial cable contact 18 is crimped onto the coaxial cable 5 from which the jacket and internal insulator 6 have been removed using a special tool.

After inserting the contacts 18 into the connector 11 of the invention, the connection between the V1 coaxial cable and the connector 3 is achieved by inserting the connector 11 into the connector pins 4. Incidentally, in the above description, an example of a combination of mutual connections between contacts has been described for a coaxial cable, but it goes without saying that the present invention can be used for other types of connections.

As explained above, the present invention has the effect of facilitating the connection between the cable and the connector pin.
