The connection with the coaxial cable 102 is performed. The connection will be described in detail. As shown in the sectional view of FIG. 14C, the sheathed cable 103 and the coaxial cable 102 are drawn in from both ends of the earth sleeve 104.

A fixed ring 105 made of metal is fixed to one end of the covered cable 103, and a core wire of the covered cable 103 is connected to an end face of the fixed ring 105. On the other hand, the coaxial cable 102 is
In 4, the jacket is removed, and the core wire is connected to the end face of the fixing ring 105. In the earth sleeve 104, an insulator pipe 106 is fitted to the sheathed cable 103 having a smaller diameter than the coaxial cable 102. Earth sleeve 10
4 is made of a metal pipe as shown in FIG.
As shown in (b), a rib portion 106-2 is formed at one end, and a step portion 106-1 is formed inside. The fixing ring 105 is formed of a metal pipe as shown in FIG.

A step 106-1 formed in the insulator pipe 106 is fixed to the tip of the sheathed cable 103 and is a portion with which a fixing ring 105 disposed in the insulator pipe 106 is engaged. The engagement of the step 105 with the step portion 106-1 prevents the covered cable 103 from coming out of the insulator pipe 106. Further, when the insulator pipe 106 is inserted into the earth sleeve 104, the rib portion 106-2 formed on the insulator pipe 106 engages with the end face of the earth sleeve 104 to position the insulator pipe 106 and the earth sleeve 104. It is for doing. Further, in order to prevent the insulator pipe 106 from coming out of the earth sleeve 104, the outer peripheral surface of the earth sleeve 104 is formed as shown in FIG.
As shown in FIG. 14C, a concave portion 104-1 is formed by caulking, and the concave portion 104 is formed on the outer peripheral surface of the earth sleeve 104 by caulking as shown in FIG. −
2 are formed.

[0005] The earthing sleeve 104 in which the coaxial cable 102 and the insulated cable 103 are connected inside as described above, has a holding portion 101-formed on one end of the main body 101 as shown in FIG. 1 is held and fixed. Note that the main body 101 is formed by processing a metal plate. A claw 101-3 bent at a right angle is formed at the other end of the main body 101. By inserting the claw 101-3 into a gap in a vehicle body or the like, the main body 101 is attached to a vehicle. Can be grounded. At this time, the shield wire of the coaxial cable 102 is in contact with the earth sleeve 104, and
4 (a), the earth sleeve 104 and the main body 1
01 is soldered at the soldering portion 101-2, so that the cable can be grounded to the vehicle body.

Next, a method of assembling the cable connector in the cable connection state shown in FIG. 14 is shown in FIGS. First, as shown in FIG.
3 is passed through the insulator pipe 106 from one end thereof. At this time, the insulated cable 103 is inserted from the rib 106-2 side of the insulator pipe 106.
Next, the covering of one end to which the covered cable 103 is connected is removed to expose the core wire 103-1. On the other hand, FIG.
As shown in FIG. 4B, the shield at the one end of the coaxial cable 102 is removed to expose the shielded wire 102-3, and at the tip thereof, the shielded wire 102-3 is removed to expose the insulator 102-2. Further, at the tip, the insulator 102-2 is removed to expose the core wire 102-1. Note that the coaxial cable 102 processed in this manner has a ground sleeve 104 inserted in advance as shown in FIG.

[0007] Next, as shown in FIG. 17 (a), a fixing ring 105 is fixed to one end of the sheathed cable 103, and the core wire of the sheathed cable 103 and the core wire 102 of the coaxial cable 102.

Next, the insulator pipe 106 inserted through the sheathed cable 103 was slid until the fixing ring 105 was engaged with the stepped portion 106-1 in the insulator pipe 106, and further inserted through the coaxial cable 102. The earth sleeve 104 is slid and fitted on the insulator pipe 106.
Thereby, the coaxial cable 102 and the sheathed cable can be connected in the earth sleeve 104 as shown in FIG. The sheathed cable 102 is a lead wire of a glass antenna or the like provided on a window glass of the vehicle, and transmits an antenna reception signal to a radio or the like provided in the vehicle by a coaxial cable 103.

In the above-mentioned conventional cable connector, a stable connection can be made by inserting the coaxial cable 102 and the sheathed cable 103 into the earth sleeve 104 to a predetermined position.
Since it is not possible to visually check the inserted length of these cables 102 and 103, it is difficult to always insert the coaxial cable 102 and the sheathed cable 103 into the earth sleeve 104 by a fixed length. Therefore,
The positional relationship between the coaxial cable 102 and the insulated cable 103 with respect to the cable connector cannot be always constant, and there is a problem that it is difficult to perform a stable connection. The earth sleeve 104 is attached to the main body 101.
However, since the fixing state is determined by soldering, the fixing state depends on the soldering state, and there is a problem that it is difficult to obtain a stable fixing state. Further, the fixing between the coaxial cable 102 and the earthing sleeve 104 and the fixing between the sheathed cable 103 and the earthing sleeve 104 depend on the recesses 104-1 and 104-2 by caulking, so that the fixing strength is improved. There was a problem that it was difficult to do.

Accordingly, an object of the present invention is to provide a cable connector having a novel configuration capable of obtaining a stable connection at all times.
