[0002]

2. Description of the Related Art As is well known, for example, in audio equipment, a connector socket as shown in FIGS. 4 to 6 mounted on a printed wiring board is sometimes used to connect an amplifier and peripheral equipment. is there. That is, this connector socket includes an insulating mold housing 2A formed on the front surface thereof with a plug insertion port 1A into which the tip of the mating connector plug X can be inserted, and extends substantially horizontally inside the plug insertion port 1A. The contact support 2a is formed in a protruding state.

In order to introduce the upper contact pin 3A and the lower contact pin 4A having the contact portions 3a, 4a at the tips into the interior of the mold housing 2A, an upper contact insertion hole 5A and a lower contact hole 5A aligned in the width direction of the mold housing 2A. A contact insertion hole 6A is formed penetratingly adjacent to the contact support portion 2a, and a corresponding upper contact pin 3A and a corresponding lower contact are formed in the lower part of the upper contact insertion hole 5A and the upper part of the lower contact insertion hole 6A. An upper pin mounting groove 7A and a lower pin mounting groove 8A capable of supporting the pin 4A are formed in a state of being connected to the corresponding upper contact insertion hole 5A and lower contact insertion hole 6A, respectively.

Therefore, a plurality of upper contact pins 3A
And lower contact pin 4A are connected to their contact portions 3a, 4
a is inserted and fixed in the upper pin mounting groove 7A and the lower pin mounting groove 8A from the back side of the mold housing 2A while being positioned in the corresponding upper contact insertion hole 5A and the corresponding lower contact insertion hole 6A. The external connection ends 3b and 4b of the contact pins 3A and the lower contact pins 4A are bent downward at substantially right angles from the intermediate bent portions 3c and 4c for connection with a printed wiring board (not shown).

[0005]

By the way, as understood from FIG. 6, the intermediate bent portions 3c and 4c of the conventional upper contact pin 3A and lower contact pin 4A have a cross-section that is smaller than that of other general portions. Notches are formed on both sides in the width direction to reduce the width of the intermediate bent portions 3c and 4c in order to reduce the order coefficient to form the strength fragile portion. Unless a bending jig is used, the lower contact pin 4A cannot be bent accurately. That is, the lower pin mounting groove 8 for mounting the lower contact pin 4A.
Since the relatively wide lower contact insertion hole 6A communicates directly below A, the narrow intermediate bent portion 4c of the lower contact pin 4A is located in the lower contact insertion hole 6A.
Unless a special bending jig was positioned at the entrance of the lower contact insertion hole 6A to support the narrow intermediate bent portion 4c, the intermediate bent portion 4c could not be accurately bent at a right angle.

Therefore, in the conventional connector socket structure, the use of the special jig causes the lower contact pin 4A.
Not only does the bending process become complicated, but also if the positioning of the jig with respect to the mold housing 2A is inaccurate, the bending state of the lower contact pin 4A becomes uncertain,
The reliability of the product sometimes deteriorated. On the contrary,
Since the upper contact insertion hole 5A is located above the upper pin mounting groove 7A, the intermediate bent portion 3c of the upper contact pin 3A is supported by the entrance Y of the upper pin mounting groove 7A, so a special jig is used. It is possible to bend accurately without using it.

SUMMARY OF THE INVENTION The object of the present invention is to solve the problem of bending the lower contact pin in the conventional position as described above.
An object of the present invention is to provide a connector socket that can accurately bend lower contact pins without using a bending jig that causes deterioration in product reliability and complicates a bending process.

In order to achieve this object, the present invention provides a contact extending in a substantially horizontal direction by forming a plug insertion opening through which the tip of a mating connector plug can be inserted in the front surface of an insulating mold housing. The support portion is placed in a protruding state inside the plug insertion port, and a plurality of contact insertion holes in the horizontal direction and a plurality of pin mounting grooves connected to these contact insertion holes are formed above and below the contact support portion. A plurality of upper and lower rows of contact pins each having a contact portion are inserted into each of the pin mounting grooves from the back side of the plug insertion port, and the external connection end portions of these contact pins are formed at substantially right angles downward from the intermediate bent portion. In the connector socket to be bent to at least, the intermediate bent portion of at least the lower contact pin has a through-hole formed at the center in the width direction, and the through-hole is formed so that it can be bent at the time of bending. Choke portion serving as a degree weakness portion thereof is to provide a connector socket which is molded on both sides of the through hole.

In the following description of the preferred embodiment of the present invention, 1) a structure in which the upper contact pin has the through hole and the choke portion, and 2) the lower contact pin is attached to the lower pin mounting groove. A structure in which the through hole is formed in the intermediate bent portion having a width larger than the width of the other general portion, and 3) the upper contact pin is attached to the upper pin mounting groove. For this reason, a description will be given of a structure in which the through holes are formed in these wide portions having a width dimension larger than the width of the other general portions.
