[Industrial applications]

 The present invention relates to a board connection terminal of a board connection type audio connector, which realizes reliable temporary fixing to printed boards having different thicknesses and can improve workability and reliability of subsequent soldering processing. It is a thing.

[0002]

[Prior Art]

 Conventionally, in audio equipment, video equipment, etc., a board-connected audio connector is attached to the front panel of the equipment, and its connecting terminals are such as those of printed circuit boards arranged in the equipment casing. It is adapted to be soldered to a through hole (hereinafter referred to as a board hole) provided at a required portion of the circuit board.

In mounting such an audio connector, the connector body is mounted on the front panel or the like, and the straight connecting terminals are mounted on the circuit board before soldering (also called dipping). Soldering is done with the board inserted in the formed hole. Since this is a temporary fixing that simply inserts the connecting terminal into the board hole, it does not have a snap-in structure in which the position of the terminal is fixed, so the position of the connector is not fixed and it takes extra assembly time. There is.

In addition, when soldering, since the terminal is simply inserted into the board hole, the terminal may come out of the board hole or float, and as a result, if soldering as it is, the connector may tilt, Problems such as incomplete connection by soldering, defective products, and pattern peeling may occur.

In view of such a point, conventionally, a kink process in which the tip side of a connection terminal of an audio connector is bent forward and backward or left and right is unevenly performed, and when the dipping process is performed, the terminal has its kink portion. It is also considered to prevent it from rising from the board hole due to the action of.

However, since the above-described kink processing is formed in accordance with the board hole of the circuit board having a predetermined thickness, for example, 1.6 mm thickness, when the board thickness changes, the kink processing at the same position and shape does not occur. Because of the inconvenience of not being able to adapt, even with the same audio connector, it was necessary to change the kink position and shape of the connection terminal according to the thickness of the circuit board used. In particular, recently, audio equipment is becoming smaller and lighter, so that, for example, the thickness of the printed circuit board is not only 1.6 mm but also various thicknesses such as 1.2 mm, 1.0 mm, and 0.8 mm. Things came to be used.

[0007]

[Problems to be solved by the device]

 Therefore, the problem to be solved by the present invention is to make a reliable temporary fixing corresponding to each thickness even if the board thickness of the mating circuit board to which the connecting terminal is connected in the audio connector is different. It is an object of the present invention to develop a board connecting terminal in a board connecting type audio connector capable of performing the above.

[0008]

[Means for Solving the Problems]

 The structure of the present invention made to solve the above-mentioned problems is a shell having a substantially cylindrical shape formed so as to be attached to a mounting panel by a screw or the like in a flange portion on the front side, and an interior of the shell. In the audio connector having a male connector member or a female connector member provided with the connector and a connecting terminal connected to the connector member so as to extend to the rear surface side of the shell. It is characterized in that a bulge portion is formed at a position where the left and right or front and rear heights of the extension end side of the terminal for use are different, and the bulge portion is temporarily fixed to a board hole of a printed circuit board having a different thickness. I will do it.

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a side sectional view of an example of an audio connector having a terminal of the present invention, FIG. 2 is a rear view of the connector shown in FIG. 1, and FIG. 3 is an enlarged rear view of the main part of the terminal shown in FIG. FIG. 4 is an enlarged rear view of another example of the terminal of the present invention, and FIGS. 5 and 6 are plan views showing the positions of the terminal of the present invention with respect to the board holes of circuit boards having different thicknesses.

In FIGS. 1 and 2, 1 has a mounting flange 2 on the front surface side and has a substantially cylindrical interior for inserting an insulator 5 holding a plurality of female connector members 41 to 43 therein. It is a metal shell formed in the shape part 3.

The insulator 5 is made of an electrically insulating material such as synthetic resin and holds the female connector members 41 to 43 in an insulated state from the shell 1. Here, the connector members 41 to 43 are formed in the shape of a thin cylinder for receiving pins by an electric conductor, that is, a thin metal plate and the like, and the connector members 41 to 43 are held in such a manner that the three members are embedded in the insulator 5, and The extending portions formed integrally with the members 41 to 43 are each slightly projected from the rear end of the insulator 5 to the outside, and are bent approximately 90 degrees from this portion, and in the example of FIGS. It is formed so as to function as the connection terminals 61, 62, 63 by being formed so as to hang toward.

The connecting terminals 61 to 63 are straight from the insulator 5 when the position of the printed circuit board PB to which the terminals 61 to 63 are connected is located immediately after the shell 1 or right next to the shell 1. It is formed so as to project, or is formed by being bent sideways by 90 degrees. This invention can be applied to connection terminals in any orientation.

In FIGS. 1 and 2, 7 is a metal barrel fitted to the outer circumference of the insulator 5, and 8 is joined to the outer circumference or the inner circumference of the rear end of the barrel 7 so as to hang down just below the shell 1. It is a noiseless lug plate. Further, 10 is a latch for holding and locking a pin connector (not shown) having a male member inserted and connected to the connector of FIGS. 1 and 2 having the female connector members 41 to 43, and 10a is a latch spring. , 10b are latch release levers, and P is a front panel of an audio device or the like to which the above audio connector is attached at its attachment flange 2.

When attaching the female connector of FIGS. 1 and 2 to the mounting panel P in the mounting hole 2a of the flange 2, the insulator 5 is pulled out from the rear surface side of the shell 1 and each terminal is removed. 61 to 63, 8 and 9 are inserted into board holes h ₁ and h ₂ etc. respectively formed in the printed board PB. Therefore, in the present invention, the length of the terminal 61 located substantially in the center of the rear surface of the connector is formed to be slightly longer than the other terminals 62, 63 and the like. That is, first, if only the terminal 61 formed in this length is inserted into the corresponding board hole (FIGS. 1, 5, and 6), the remaining terminals 62, 63, etc. are all in the corresponding board holes h. It will be positioned on ₁ , h _2, etc. Therefore, the other terminals can be inserted as they are without being aligned with the board holes, which improves workability.

In the temporary fixing by inserting the terminals 61 to 63 into the board holes as described above, even if there is a difference in the thicknesses t ₁ and t ₂ of the boards P B and PB ′, they can correspond to the respective thicknesses. In order to secure the temporary fixing effect by changing the position of the board hole, the terminals 62 to 63 of the present invention are attached to the terminals 62 and 63, for example, as shown in FIG. , 62b, 63a, and 63b are formed with different heights, while the positions of the board holes are slightly changed for each board thickness. Incidentally, 62c and 63c are reinforcing ribs formed between the respective bulging portions.

That is, in the terminals 62 and 63, above the left and right bulging portions 62a and 62b and 63a and 63b, positions corresponding to the thickness of the substrate from the rising ends of the respective bulging portions 62a to 63b are provided. Steps 62d and 63d are formed at the bottom. That is, each of the bulging portions 62a to 63b has a bulge for bulging from a position corresponding to the thickness of the substrate as viewed from the stepped portions 62d and 63d.

The bulging portions 62a, 62b and 63a, 63b having different heights are respectively provided in the substrate holes h ₁ , h ₂ or h ₁ ', h of the substrate PB or PB' having different thicknesses. when inserted into the ₂ ', to fulfill the locked and temporarily fixed function to the edge of each hole, the substrates holes according to the thickness of the substrate, respectively, FIG. 5, holes h ₁ as shown in FIG. 6, h ₂ and the hole h _'1, h' is to form by shifting the positions of _two.

As a result, the terminals 62 and 63 inserted into the board holes h ₁ and h ₂ of the board PB having a small thickness t ₁ have outer bulges in which bulges are raised from a position higher than the lower end. The terminals 62 which are locked to the edges of the holes h ₁ and h _{2 by} the portions 62a and 63a (see FIG. 5) and are inserted into the board holes h ′ ₁ and h ′ ₂ of the board PB ′ having a large thickness t ₂ , 63 are locked at the edges of the holes h ′ ₁ , h ′ ₂ by the inner bulging portions 62b, 63b raised from a lower position than the bulging portions 62a, 63a (see FIG. 6).

The bulged portions 62a, 62b and 63a, 63b of the terminals 62, 63 described above may be formed as shown in FIG. 4, the same reference numerals as those in FIG. 3 indicate the same portions or the same members, but 62e and 63e are slits formed between the left and right bulged portions 62a and 62b and the same 63a and 63b.

Although the above description is for the female terminal type board connection type audio connector, the present invention is also applicable to the male terminal type board connection type audio connector in which the connector member 41 is a pin connector. It can be applied as is.
