Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for mounting on a printed circuit board.

[0002]

2. Description of the Related Art As electronic devices have become thinner, the amount of surface mount components mounted on the surface of a printed circuit board has been increasing, and jacks such as a power jack have also been mounted on the printed circuit board. . However, unlike other surface mount components such as circuit elements, jacks are difficult to make thin,
This is one factor that hinders the thinning of electronic devices.

A so-called board-fitting type jack has been proposed against such a background. For this, a jack as disclosed in Japanese Utility Model Laid-Open No. 2-29178 has been devised. The body of the jack is substantially box-shaped, and only its front face is open. A plug is inserted into the opening. A pin is provided on the rear surface of the body. In addition, a groove is provided at the center in the height direction on both side surfaces of the body main body.

On the other hand, a U-shaped cutout portion and a soldering land at a position corresponding to the pin on the rear surface of the body of the inserted jack are formed on a printed circuit board for fixing the jack. . The body body is inserted horizontally into the cutout of the printed circuit board from the rear surface. At that time, the printed circuit board is fitted into the groove of the body main body, and the printed circuit board is inserted until the rear surface of the body comes into contact with the inside of the notch. Then, the body main body is fixed to the printed circuit board by soldering the pins on the rear surface of the body main body and the soldering lands at the corresponding positions.

According to this structure, the center of the body in the height direction is supported by the printed circuit board, and the body is protruded above and below the printed circuit board.
Thinning is promoted.

A similar board fitting type jack is disclosed in
No. 68351 also shows this. In this board fitting type jack, a positioning projection is extended from the rear surface of the body of the jack so that the body of the jack is not twisted with respect to the printed circuit board. Also, on the inner surface of the groove for mounting the printed board provided on the side of the body main body, a ridge is extended from the groove, and when the body of the jack is inserted into the printed board, the ridge is attached to the printed board. It is set to apply pressure. As a result, the frictional force between the body of the jack and the printed circuit board is increased as compared with the conventional case.

[0007]

However, the conventional board-fitting jack has the following problems. The means for fixing the body to the printed circuit board, the direction of pulling the body out of the printed circuit board, the friction force between the groove on the side of the body of the jack and the printed circuit board and the pins on the body and corresponding Only the soldering with the soldering land at the position to be performed is performed, and no other secure locking means is provided.

That is, when a plug inserted into the body of the jack is to be pulled out from the body of the jack, the pulling force acts in a direction in which the body of the jack comes off the printed circuit board. The magnitude of the force is often larger than the frictional force between the groove on the side of the body of the jack and the printed circuit board. Therefore, the force exceeding the frictional force is applied only to this soldered portion. Therefore, there is a risk that the soldering land and, consequently, the circuit pattern connected to the land will peel off. In addition, when the plug is removed, stress (twisting) is often applied from all directions, and there is a high danger that the circuit pattern will be further separated due to the kinking of the printed circuit board.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a printed circuit board and a board mounting connector which can be subjected to stress (twisting) from all directions when the printed circuit board supports the board mounting connector. An object of the present invention is to provide a board mounting connector in which the solder connection between the connectors is not separated.

Reference). The projections 105 and 106 have a shape in which the lower surface is most protruded so that when the locking body 120 is fitted into the lower surface thereof, it is difficult to come off.

The contacts 190, 191 and 192 are
As shown in FIGS. 3 and 6, it is installed from the inside of the body main body 100 to the rear surface side, and is capable of contacting a printed circuit board 900 outside the body main body 100. The contact 190 includes a movable contact piece 190a (see FIG. 6), a movable contact support 190b, and a land contact 190c. The movable contact piece 190a is a movable contact piece protruding rightward when viewed from the front of the body 100. The movable contact piece support portion 190b is a portion for supporting the contact 190 with respect to the body main body 100. The land contact portion 190c is a portion that contacts the soldering land 920 on the printed circuit board and is fixed by soldering.

The contact 191 is fixed to the fixed contact piece 191.
a and a land contact portion 191c. Fixed piece 1
Reference numeral 91a denotes a portion where the movable contact piece 190a of the contact 190 can contact (contacts when the plug is not inserted). It is a part for supporting. The land contact portion 191c is connected to the solder land 9 on the printed circuit board.
21 and is a portion fixed by soldering.

The contact 192 includes a cylindrical shaft portion 192a fitted to the inner surface of the plug, a fixed portion 192b, and a land contact portion 192c. The fixing portion 192b is a portion for supporting the contact 192 with respect to the body 100. The land contact portion 192c is a portion that comes into contact with the soldering land 922 on the printed board and is fixed by soldering.

Therefore, when the shaft of the plug (not shown) is inserted from the plug insertion opening 150 on the front surface of the board mounting connector 10 as the power jack, the inner surface of the shaft of the plug fits into the cylindrical shaft portion 192a. Then, the outer peripheral surface of the shaft of the plug is fitted so as to push away the movable contact piece 190a. At this stage, the movable contact piece 190a and the fixed contact piece 191a are in a non-contact state.

Therefore, the plug has a frictional force between the inner surface of the shaft and the cylindrical shaft portion 192a of the contact 192, a frictional force between the inner surface of the board mounting connector 10 and the outer peripheral surface of the plug shaft, and The movable contact piece 190a, which is deformed by insertion and returns to the original state, is held on the board mounting connector 10 by the pressure (frictional force) on the outer peripheral surface of the plug shaft of the movable contact piece 190a. These frictional forces are applied at least when the plug is unplugged from the board mounting connector 10. Further, when the plug is pulled out, if the plug is pulled out, the frictional force between the inner surface of the board mounting connector 10 and the outer peripheral surface of the shaft of the plug is further increased.

Next, a method for forming the locking body 120 and a method for mounting the locking body 120 on the body 100 will be described with reference to FIG. The locking body 120 is made of one strip-shaped metal plate. The one strip-shaped metal plate is bent into a U-shape (to match the shape of the outer peripheral surface at the mounting position of the body main body 100). On both sides 121a, 121b, substantially U-shaped through holes 122a, 122b are provided. By slightly raising the portion surrounded by the substantially U-shape outward, the locking claws 120a and 120b of the locking body 120 are formed.

It should be noted that the degree of raising outward is such that the locking claw portion has a strength enough to sufficiently oppose the force applied in the direction in which the body main body 100 comes out of the printed circuit board 900 (to the extent that the locking does not hinder the locking described above). 120a and 120b can be maintained. In this case, it is needless to say that the thickness of the metal plate is sufficient to maintain its strength. Further, both sides 121a and 121 of the locking body 120 are provided so that the locking body 120 can be easily mounted on the body main body 100.
A chamfered portion is formed at the lower corner of b.

The locking body 120 is attached to the dug portions 170 and 171 of the body 100.

For this reason, when the locking body 120 is inserted into the body main body 100 from the direction D in FIG. 8, the locking body 120 is made of a metal plate. The lower ends of the substantially U-shaped through holes 122a and 122b pass over the convex portions 105 and 106 (see FIG. 6), and the locking body 120 is locked by the convex portions 105 and 106. Since the depths of the dug portions 170 and 171 are set to be the same as the thickness of the locking body 120,
When the locking body 120 is attached to the body main body 100, the locking body 120 is embedded in the body main body 100. Therefore, when the board mounting connector 10 is inserted into the printed circuit board 900 as described later, The stop 120 is not in the way.

The metal plate of the locking body 120 is a metal such as iron. The body 100 is made of insulating synthetic resin. By the way, the locking body 120 may be mounted on the body main body 100 in advance as described above, or when the body main body 100 is locked on the printed circuit board 900, the locking body 120 may be mounted on the body main body 100. The same effect can be obtained by mounting the 120. The thus configured board mounting connector 10 is inserted into the cutout portion 910 of the printed circuit board 900 from the direction A shown in FIG.

The mounting procedure will be described.
The contact 1 is provided on the upper surface on both sides of the opening of the
The body main body 100 is pushed horizontally while bringing the lower surfaces of the land contact portions 190c and 191c of the 90 and 191 into contact. Then, the notch 910 is formed in the gap 111c of the right rear holding portion 111 protruding from both side surfaces of the body body 100 and the gap 113c of the left rear holding portion 113 (see FIG. 3). Right side 911 and left side 912 of opening

At the same time, the body main body 100 is pressed so that the right side 911 of the opening 0 is fitted, and the body main body 100 is press-fitted so that the left side 912 of the opening of the cutout 910 is fitted into the gap 113c. I do.

When the body body 100 is further press-fitted,
To the right side 911 of the opening of the notch 910, the locking body 1
20 and the locking claw portion 120a on the right side thereof reaches at the same time.
The left locking claw 120b of the zero reaches. When the body 100 is further pushed in, the locking claws 120a, 120
b is the inner end 91 of the right side 911 of the notch 910
1a and the inner end 912a of the left side portion 912 are pushed into the inside of the body 100. Therefore, a relatively small force is applied to the body body 100 so far, and the body body 1
00 can be pressed.

When the body body 100 is further press-fitted,
To the right side 911 and the left side 912 of the notch 910,
The grooves of the substantially U-shaped holding parts 110 and 112 reach. The right part 911 and the left part 91 of the notch 910 are formed in the groove.
The body body 100 is press-fitted until 2 enters and comes into contact with the inner surface.

At this stage, the retaining notch 9 provided in a part of the notch 910 of the printed circuit board 900
Since the locking claw portions 120a, 120b reach the 10a, 910b completely, the locking claw portions 120a, 120, which have been previously pushed toward the body body 100, have been left.
b returns to the original position with respect to the space of the retaining notches 910a and 910b.

Therefore, the locking claws 120a, 120b
Functions as a locking mechanism in a direction in which the board mounting connector 10 comes out of the printed circuit board 900 (hereinafter, this direction is referred to as a front direction). Also, at this stage, the board mounting connector 10 has the holding portions 110, 111, 112, 113.
Thus, they are held (supported) in close contact with the printed circuit board 900 in the rearward direction, the left-right direction, and the vertical direction. Therefore, the locking claws 120a, 120b
The board mounting connector 10 is held (fixed) in close contact with the printed circuit board 900 in the front-rear, left-right, and up-down directions, in combination with the front locking by the above.

At this stage, the contacts 19 of the board mounting connector 10 contact the soldering lands 921, 922, 923 (see FIG. 7) provided on the printed circuit board 900.
0, 191, 192 land contact portions 190c, 191
Since c and 192c are in contact, they are fixed by soldering.

Accordingly, when the printed circuit board 900 supports the board mounting connector 10, even if stress (torsion) from all directions is applied to the board mounting connector 10, the board mounting connector 10 is printed. Substrate 9
Hold (fixed) in close contact with the front, back, left, right and up and down directions with respect to 00
Since no excessive force is applied to the solder connection portion, the solder connection between the printed board 900 and the board mounting connector 10 does not peel off. That is, even if a plug (not shown) is inserted into the board mounting connector 10 and the plug is pulled out while being prying, the solder connection between the printed circuit board 900 and the board mounting connector 10 does not peel off.

Incidentally, the locking claws 120a of the locking body 120,
Only 120b may be provided. Also,
