Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting a lamp socket, and more particularly to a connector for connecting a lamp socket of a bead ball used as a decoration for a pachinko machine or the like. .

[0002]

2. Description of the Related Art In a pachinko machine, many bean balls are used in order to improve the taste. Such a bead ball 1 is not provided with a screw-in type socket, for example, as shown in FIG. 7 and FIG.
And the lead terminals 1a, 1a of the bead ball 1 are led out from terminal holes 2a, 2a formed in the bottom of the socket 2.

On the other hand, the printed circuit board 3 has the terminal holes 2
pin-shaped connection terminals 4a1, 4a1
4a1 is erected. These connection terminals 4a1, 4a
Reference numeral 1 denotes a tip of the lead terminals 4a, 4a of the connector 4 disposed on the back side of the printed board 3, and the lead terminals 4a, 4a.
4a protrudes from the back side of the connector housing 4b mounted in parallel with the printed circuit board 3, and is bent 90 degrees so as to be perpendicular to the printed circuit board 3 side.

When mounting the socket 2, the connection terminals 4a1 and 4a1 are inserted into the terminal holes 2a and 2a on the bottom surface. Then, the lead terminal 1a is pressed against the peripheral surface of the connection terminal 4a1 in the terminal hole 2a, and is electrically connected, and the connection terminal 4a1 is forcibly inserted into the terminal hole 2a, so that the socket 2 itself is fixed. . Although the connection terminals 4a1 and 4a1 are soldered to the printed circuit board 3, they may be soldered on the mounting surface side of the connector 4 on the printed circuit board 3 in some cases.

[0005]

In the above-described conventional connector for connecting a lamp socket, when soldering is performed on the mounting surface side of the connector on the printed circuit board 3, the solder bath cannot be passed. Therefore, although soldering must be performed manually, a plurality of lead terminals 40 are required.
As shown in FIG. 9, a and 4a protrude from the connector housing 4b at a small interval of about 2 or 3 mm.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a lamp socket connector that can be easily soldered without causing a solder bridge.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, a fitting housing portion that can be fitted and connected to a mating connector, and one end is inserted into the fitting housing portion. And a plurality of lead terminals having the other ends extending perpendicular to the mounting surface of the fitting housing portion, and extending from the fitting housing portion to between the plurality of lead terminals. And a partition part for partitioning between the lead terminals.

In the invention according to claim 1, the lead terminals protruding from the fitting housing portion are extended so that the other end is perpendicular to the mounting surface, and each of the lead terminals is extended. A partition part extending from the fitting housing part is located between them. When mounting the lamp socket connection connector on the printed circuit board, when approaching from the mounting surface side, a lead terminal extending toward the mounting surface has a predetermined through hole formed in the printed circuit board. And penetrates to the back side as it is. When the fitting housing portion is inserted until it is at a proper position with respect to the mounting surface of the printed circuit board, the partition portion comes into contact with the mounting surface of the printed circuit board, and in this state, the lead terminals are separated. Therefore, when soldering to the lead terminals, since there is the same partition wall, no solder bridge is generated between the lead terminals.

Here, the fitting housing portion may be any one that can be fitted and connected to the mating connector, and its shape can be appropriately modified, and the difference between male and female is not particularly limited. . However, since the protruding lead terminal penetrates the printed circuit board and is soldered on the mounting surface side, it is necessary to have a structure in which a portion where the lead terminal penetrates the printed circuit board is opened. Therefore, as for the lead terminal, at least one end may be inserted into the fitting housing portion and the other end may project outside, but if it protrudes from the bottom surface side of the fitting housing portion, the lead terminal may be in contact with the mounting surface of the printed circuit board. It is necessary to form a partition between them, and if it protrudes from the side surface of the fitting housing portion, it is necessary to bend substantially 90 degrees toward the mounting surface.

When projecting from the side wall surface, the partition portion extends laterally from the fitting housing portion between the lead terminals. Then, on the basis of the lead terminal penetrating the printed circuit board, the fitting housing portion is located on one side and is in contact with the printed circuit board, and the partition is located on the other side and is in contact with the printed circuit board. The parallelism to the substrate is improved. By the way, the partition part may be extended from the fitting housing part between the lead terminals to partition the lead terminals, but the shape can be appropriately modified. Of course, it may be composed of a plate-shaped partition wall. For example, if the upper surface is formed to have an acute angle, even if the melted solder is likely to form a bridge, it can be divided at the upper surface. Also, if the cross section is T-shaped, the degree of exposure of the lead terminals is reduced, and solder bridges are less likely to occur.

[0011]

As described above, according to the present invention, since the partition wall portion is extended so as to separate the lead terminals from the connector housing portion, when the soldering work is performed from the side of the mounting surface to the printed circuit board, It is possible to provide a lamp socket connection connector that does not easily cause a bridge and that can facilitate a soldering operation.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a connector for connecting a lamp socket and a printed circuit board according to an embodiment of the present invention.

In FIG. 1, a printed circuit board 10 is configured so that a connector 20 to be described later can be mounted from the front side having the printed patterns 12, 12, and the printed pattern 12, 12 is soldered to the connector 20. The electrical connection between the patterns 12, 12 and the connector 20 is made. On the other hand, the connector 20 includes a housing portion 22, a pair of lead terminals 24, 24, and a partition wall portion 26, and each lead terminal 24, 24 penetrates through a pair of through holes 12a, 12a arranged on the printed circuit board 10. While letting
The housing 22 is mounted on the printed circuit board 10 so as to contact the front surface of the board.

The housing portion 22 is formed in a substantially rectangular shape. The front surface is formed so as to be able to be fitted with a mating connector (not shown), and the rear surface has a partition wall portion 26 and a pair of lead terminals 24, 24 extending therefrom. It has been put out. Here, the housing portion 22 may have any configuration as long as it can electrically connect the mating connector to be fitted and the extended lead terminals 24, 24. Therefore, the shape of the housing portion 22 is not necessarily the same as described above. It is not necessary to be substantially rectangular, and it may be cylindrical or the like in accordance with the shape of the mating surface with the mating connector. Further, in the present embodiment, the housing portion 22 is mounted while being in close contact with the printed circuit board 10. However, if the partition terminals 26 can partition the lead terminals 24, 24, such a configuration is not necessarily required. It is not necessary. For example, as shown in FIG. 2, the housing portion 22 may rise vertically from the printed circuit board 10 and the fitting surface with the mating connector may be directed upward. Further, the housing portion 22 and the mating connector need only be configured so as to be able to fit together in a male-female relationship or the like, so that the housing portion 22 may be a male type or a female type.

The lead terminals 24 extend from the housing 22 and are bent in an L-shape in the middle of the partition 26 so as to extend through the through holes 12 a provided on the printed circuit board 10. When penetrated from the front side, a lamp socket (not shown) can be attached to a portion protruding to the rear side. At this time, when the lead terminals 24, 24 are soldered to the printed circuit board 10 on the front side of the printed circuit board 10, the partition wall 2 is formed so that soldering can be performed at a position where a solder bridge does not occur between the two lead terminals 24, 24.
6 is bent in the middle, but it is not always necessary to bend in the middle as described above since the partition 26 may be arranged so as to partition between the two lead terminals 24, 24. The lead terminals 24, 24 are
It may be bent at the base portion extending from 2. However, if the lead terminals 24, 24 are longer than usual, the soldering work by hand becomes easier. The extended lead terminals 24, 24 can be soldered to the printed circuit board 10 from the front surface side, and the number and shape of the terminals are appropriately determined as long as a lamp socket (not shown) can be mounted on the back side of the printed circuit board 10. Can be changed.

The partition 26 is a plate-like housing 1.
The second lead terminal 24 extends from the center of the rear surface of the second terminal 2 so as to block the space between the two lead terminals 24. At this time, the partition part 26 and the printed circuit board 10 have a shape so as to be in close contact with each other, and there is no gap between them. Therefore, one lead terminal 2
When soldering the printed circuit board 4 to the printed pattern 12, the solder does not flow along the printed circuit board 10 to the other lead terminal 24 side. Here, the partition wall portion 26 may be extended in a shape that does not cause a solder bridge between the lead terminals 24, 24 when the lead terminals 24, 24 are soldered to the printed circuit board 10. However, it is not always necessary that the lead terminals be formed in a plate shape as described above. As shown in FIG. , That is, a triangular cross section. If the partition wall 26 is formed with an inclination in this manner, even if the solder flows into the partition wall 26, the two lead terminals 24, 2 are formed.
When the solder flows down in four directions, both lead terminals 2
It becomes possible to perform soldering without forming a solder bridge between 4, 24. Further, as shown in FIG. 4, the plate-like partition 26 is placed on the respective lead terminals 24,
It may have a shape extending horizontally in 24 directions, that is, a T-shaped cross section. When the horizontal partition is provided above the partition 26 in this way, even when a large amount of solder is applied, the solder runs over the partition 26 from both the lead terminals 24, 24, and a solder bridge is generated. The possibility disappears.

Next, the operation of this embodiment having the above configuration will be described. While the lead terminals 24, 24 bent in an L-shape penetrate from the front side to the back side of the printed circuit board 10, the lead terminals 24, 24 are connected to the printed patterns 12, 12 while the partition 26 is brought into close contact with the printed circuit board 10. When soldering is performed from the front side, the partition 26 prevents the formation of a solder bridge between the two lead terminals 24, 24. By adopting such a configuration, normally, as shown in FIG.
The space between the four is divided, and attention to the prevention of the solder bridge in the soldering work is eased, and the work efficiency is improved. When the amount of solder has increased, as shown in FIG. 6, the solder flowing from the two lead terminals 24, 24 in the direction toward the center is blocked by the partition 26 to prevent the occurrence of a solder bridge.

As described above, when the lead terminals 24, 24 extended from the connector 20 are soldered to the printed circuit board 10 from the side where the connector 20 is provided, the lead terminals 24, 24 are separated from each other. Connect the partition 26 to the connector 2
When extending from zero, soldering can be performed without generating a solder bridge between the two lead terminals 24, 24.
