A notch 12c is provided at the front edge of a, and a locking hole 12d for locking the cover 16 is provided at the top.

The socket main body 13 is a resin molded product formed into a substantially cylindrical shape, and has a front surface 13a having a plurality of insertion holes (eight in this embodiment) 13b drilled in the axial direction, and a plurality of insertion holes 13b provided on the outer periphery. Trapezoidal groove 1
3c opens. Furthermore, protrusions 13d protrude from the outer periphery of the socket body 13 at predetermined intervals.

Reference numeral 18 denotes a ground terminal, which has a tip portion 18a bent in a dogleg shape and a stopper portion 18 bent in a U shape.
b, and a claw portion (projection portion) 18c whose end portion extends near the stopper portion 18b and projects obliquely so as to be elastically deformable, and is soldered to the shield case 14 as described later.

The shield case 14 is made of a brass plate that is press-molded and then plated with nickel, and has an arcuate portion 14a that covers the lower half of the outer circumference of the socket body 13.
and bifurcated arm portions 14b and 14c that are bent from the arcuate portion 14a and hold the cable 17.

As shown in FIG. 2, the shield case 14 has a cut-out portion 14d formed on the inner circumferential surface of the circular arc portion 14a, which is pressed so as to protrude into a tunnel shape. The cut-and-raised portion 14d protrudes in a substantially trapezoidal shape, and forms a space 19 below into which the ground terminal 18 is inserted. Further, a positioning hole 14e into which the protrusion 13d of the socket body 13 is inserted is bored in the arcuate portion 14a.

As shown in FIG. 3, when fixing the ground terminal 18 to the shield case 14, the claw portion 18c of the ground terminal 18 is first fitted into the space 19 below the cut-out portion 14d. That is, the claw portion 18c of the ground terminal 18 is press-fitted into the space 19 while being bent, and its elastic force presses the lower surface of the cut-and-raised portion 14d.
Further, the vertical surface of the stopper portion 18b is the cut-out portion 14.
The claw portion 18c fits into the space 19 to a position where it abuts the portion d. Therefore, the ground terminal 18 is positioned by the stopper part 18b that comes into contact with the end face of the cut-and-raised part 14d, and is held by the claw part 18c that presses the cut-and-raised part 14d.

Therefore, the ground terminal 18 is connected to the shield case 1.
It is temporarily locked in the predetermined position of 4. Then, the claw portion 18c and the cut-out portion 14d are connected and fixed with solder 20.

In this way, since the ground terminal 18 is soldered while being locked in a predetermined position of the shield case 14, the ground terminal 18 can be fixed to the shield case 14 more precisely and easily.

Further, the shield case 15 is formed by press-molding a conductive material so as to form a pair with the shield case 14. The shield case 15 includes an arcuate portion 15a that covers the upper half of the socket body 13;
The back part 15b bent from a and the back part 15b
It consists of holding parts 15c and 15d which are bent on both sides to hold the cable 17, and an extension part 15e which extends downward from the back part 15b.

The cover 16 is molded from synthetic resin and has an engaging portion 16a at its upper end that engages with the locking hole 12d of the socket cover 12.

As shown in FIGS. 4 and 5, when assembling the connector socket 11, first connect multiple cables 17.
a into the insertion holes 13b of the socket body 13, respectively.
Connect to the contact 21 provided inside. Next, the lower half of the socket body 13 is covered with the shield case 14 to which the ground terminal 18 is fixed as described above, and the upper half of the socket body 13 is also covered with the shield case 15. In addition, the shield case 14,1
5 are holes 14e and 15f in the arcuate portions 14a and 15a.
The protrusion 13d is inserted into the arcuate portion 1 and positioned.
The edges of 4a and 15a are brought into contact. Earth terminal 1
8 is a groove 13c as a relief part of the socket body 13
The tip 18a faces the notch 12c.

Arm portions 14b, 1 of the shield case 14
Bend 4c, cable 17, shield case 15
The extending portion 15e and the ground wire 17b are connected to the arm portion 14.
It is held between b and 14c. As a result, the shield cases 14 and 15 are connected to the ground wire 17b, magnetically shielding the connection portion between the socket body 13 and the cable 17a.

Next, attach the socket body 13 to the socket cover 12.
The socket cover 16 is fitted into the circumferential portion 12a of the socket cover 12, and the cover 16 is attached to the back surface of the socket cover 12. cover 16
is attached to the socket cover 12 by engaging its engaging portion 16a with the locking hole 12d, and holds the cable 17 between it and the holding portion 12b of the socket cover 12.

In this way, the assembled connector socket 1
1 is inserted into a connector (not shown) attached to, for example, audio equipment to connect the equipment.
When connector socket 11 is inserted into the connector,
As shown in FIG. 2, first, the end of the shield case 22 of the connector is
Connects the shield cases of both connectors. Further, as the connector socket 11 is pushed in, the tip 18a of the ground terminal 18
is in sliding contact with the circumferential surface of the shield case 22, and the connector pin (not shown) is in contact with the socket body 1.
3 into the insertion hole 13b and connect to the contact 21.

Note that when the shield case 22 comes into contact with the tip 18a of the ground terminal 18, the tip 18a bends in the direction of arrow A (shown in FIG. 3). However, although the stopper portion 18b is elastically deformed by the displacement of the tip portion 18a, the displacement of the tip portion 18a is not transmitted to the claw portion 18c soldered to the raised portion 14d. Therefore, when the connector socket 11 is inserted, the force that tends to displace the claw part 18c of the ground terminal 18 is absorbed by the stopper part 18b, so the claw part 18c is soldered to the cut-out part 14d. The condition can be maintained stably.

In addition, in the above embodiment, the claw portion 1 is attached to the ground terminal 18.
8c is cut and raised, but its shape is not limited to this. For example, the earth terminal 18 may be provided with an elastically deformable protrusion, and this protrusion may be press-fitted into the space 19 of the cut and raised part 14d. good.

Effects of the invention As mentioned above, the connector socket according to the invention has no problems when connecting the ground terminal to the shield case.
Since the protruding part is simply press-fitted into the space of the cut-and-raised part until the stopper part comes into contact with the cut-and-raised part, workability during the assembly process can be easily performed. Also, when the protruding part is press-fitted into the space of the cut-and-raised part, the end of the protruding part slides into the cut-and-raised part and elastically deforms so that the inclination angle becomes smaller, and the protrusion is press-fitted into the space of the cut-and-raised part. The ground terminal can be held in place, making it easier to solder to the shield case. Furthermore, by fitting the protruding part of the ground terminal into the cut-out part of the shield case, the ground terminal can be positioned at the predetermined mounting position of the shield case. The mounting accuracy is higher, and the ground terminal does not wobble during soldering, so the soldering work does not require much effort and the ground terminal can be easily soldered.
