Abstract

PURPOSE:To dispense with tilt-correction after solder-dipping with tilt after fitting to a PCB prevented, by providing a projection for preventing tilt on fitting leg parts in a connector socket. CONSTITUTION:In a connector socket having a jack body 1, having plural jacks 9, and fitting leg parts 5, provided in the rear of the jack body 1, a projection 6, having the same plain as the lower surface of a spacer 4, is formed on the jack body front surface 1a side of the fitting leg parts 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector socket, and more particularly to a connector socket provided with a tilt preventing function so that a 21-pin jack or the like can be vertically mounted on a printed circuit board.

[0002]

2. Description of the Related Art Generally, a connector socket such as a 21-pin jack is mounted on a printed circuit board (hereinafter referred to as PCB) and then a plug board is mounted on the front surface thereof.
The plug board cannot be attached unless the connector socket is attached vertically to the PCB. In the conventional connector socket, as shown in FIG. 5, the rod-shaped mounting leg portions 5 and the contacts provided on both sides of the jack body 1 are inserted into the mounting holes and the through holes of the PCB 8, and the PCB 8
The contact 3 that protruded downward was soldered.

[0003]

However, in such a conventional connector socket, the jack body 1 may tilt in the front direction (direction of arrow A in FIG. 5) by its own weight before the solder dipping process. Therefore, there has been a problem that a troublesome work such as correcting the inclination after the solder dipping or attaching the solder is required.

The present invention has been made in view of the above conventional problems. By providing a protrusion for preventing inclination on the mounting leg portion, the inclination after mounting on the PCB is prevented,
An object of the present invention is to provide a connector socket that does not require tilt correction after solder dipping.

[0005]

According to the present invention, there is provided a jack body having a plurality of jacks, mounting legs provided on both sides of the jack body and attached to a printed circuit board, and the printed circuit board provided at a rear part of the jack body. In a connector socket provided with a spacer for holding a space between the spacer and the connector, a protrusion having a lower surface in the same plane as the lower surface of the spacer is provided on the front surface side of the jack body of the mounting leg portion.

[0006]

According to the present invention, when the mounting leg is inserted into the mounting hole of the PCB and the contact is inserted into the through hole, the spacer and the lower surface of the protrusion come into contact with the upper surface of the PCB. Without leaning
Solder dip processing is performed while maintaining the vertical state.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 are views showing an embodiment of a connector socket according to the present invention.

First, the structure will be described. The same parts as those in FIG. 5 are denoted by the same reference numerals. 1 to 4, 1
Is a jack body, and the jack body 1 is a so-called 21-pin jack body that is a rectangular box body that is open to the front and has 21 jacks 2 formed on the opening front surface. Mounting legs 5 and 5 are integrally formed on both sides of the jack body 1, and the lower ends of the mounting legs 5 and 5 are formed in a plate-shaped PCB 8 and penetrate the mounting holes 10 and 10. A tape-shaped convex portion 7 is formed at the lower end of the mounting leg portion 5 and engages with the lower surface of the PCB 8. On the rear part of the jack body 1, there is a spacer 4 which holds a space between the jack body 1 and the PCB 8.
The bottom surface of the spacer 4 and the convex portion 7 of the mounting leg portion 5 sandwich the upper surface and the lower surface of the PCB 8 between them.

A projection 6 facing the front surface 1a of the jack body 1 is formed in the lower portion of the mounting leg portion 5.5. The lower surface 6a of the protrusion 6 and the lower surface 4a of the spacer 4
Are configured to be coplanar with the top surface of the PCB 8. 3 is a contact connected to the jack 2,
The contact 3 is bent at a right angle behind the jack body 1 and extends toward the PCB 8 side. As shown in FIG. 2, a through hole 9 corresponding to the contact 3 is formed in the PCB 8, and the lower part of the contact 3 penetrates through.

Next, the operation will be described. The mounting legs 4 and 4 of the jack body 1 are inserted into the mounting holes 10 and 10 of the PCB, and the contact 3 is inserted into the through hole 9. The spacer 4 and the projection 6 stop at the position where the lower surfaces of the spacer 8 and the projection 6 contact the upper surface of the PCB 8, and at this position, the connector socket has the spacer 4 and the projection 6
It is supported by the lower surface 6a and is held vertically. Then, in this state, the contact 3 is soldered by solder dipping. In this case, the connector socket has a protrusion 6
Therefore, the jack body 1 is prevented from falling in the direction of the front surface 1a, always kept in a stable vertical state, and normal soldering is always possible.

[0011]

As described above, according to the present invention,
Since the protrusion that forms the same plane as the lower surface of the spacer is formed on the front side of the jack body of the mounting leg, the connector socket does not tilt forward after mounting on the PCB, it is always held vertically and stably, and the solder dip It is not necessary to correct the inclination afterwards or to retrofit it, and it is possible to improve accuracy and significantly reduce manufacturing cost.
