Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has two types of terminals, of which one terminal and the other terminal can be electrically connected to terminals of different types respectively. The present invention relates to a conversion connector, and particularly to a conversion connector of a board connection type in which one terminal and the other terminal are electrically connected via a substrate.

[0002]

2. Description of the Related Art Japanese Patent Laying-Open No. 6-203934 discloses a conversion connector of this type, that is, a board connection type conversion connector. In this conversion connector, a pin plug, a board, and a pin connector are housed in a cabinet, and a center terminal of the pin plug and a pin of the pin connector are electrically connected via the board. In this conversion connector, the electrical connection between the pin of the pin connector and the board is made by extending the pin of the pin connector straight behind the fixing mold holding the pin, and the tip of the extended portion. Is soldered to the substrate.

On the other hand, conventionally, a conversion connector shown in FIG. 7 has been known. In this conversion connector, the other party's first
A first terminal unit 10 having a first terminal (not shown in the figure) to which an RGB connector (not shown) as a terminal is electrically connected, and an RCA connector (not shown) as a counterpart second terminal are electrically connected. A second terminal unit 20 that is inserted and connected in a flexible manner, and a board (wiring board) 30 that electrically connects the first terminal of the first terminal unit 10 to the second terminal 21 of the second terminal unit 20 It is housed and fixed in the case 40. In this conversion connector, the electrical connection between the second terminal 21 of the second terminal unit 20 and the board 30 is
Connect one end of the lead wire 50 to the connection piece 22 on the second terminal 21 side.
And the other end of the lead wire 50 is connected to a socket 51, and the socket 51 is connected to the plug 31 mounted on the substrate 30 by plugging.

[0004]

However, in the conversion connector described in Japanese Patent Application Laid-Open No. 6-203934, the pins of the pin connector are extended straight behind the fixing mold, and Since the tip is soldered to the board, if the pin of the pin connector is torn, such as when inserting or removing the RCA connector from the pin connector, the resulting excessive force from the pin to the board via the extended portion There is a possibility that the conductive foil (for example, copper foil) of the board, which is the soldering location, may be peeled off and transmitted to the soldering location.

On the other hand, in the conventional conversion connector described with reference to FIG. 7, even if the second terminal 21 is twisted when the RCA connector is inserted into or pulled out of the second terminal unit 20, the force generated by the second terminal unit 20 is not applied. Since the wire 50 is absorbed by the bending deformation and an unreasonable force is hardly applied to the soldered portion between the lead wire 50 and the substrate 30, the possibility that the conductor foil of the substrate is peeled off is extremely higher than that of the above publication. There is the advantage of being less. On the other hand, the conversion connector of FIG. 7 includes not only the lead wire 50 but also the socket 51 and the plug 3.
1 is required, the number of parts is increased, and the connection terminal 22 having a complicated shape for crimping and connecting one end of the lead wire 50 to the second terminal 21 must be provided. There was a problem that the cost was likely to be high.

The present invention has been made under the above circumstances. In the conversion connector of the board connection type described at the beginning, for example, a twisting force is applied to the terminal of a terminal unit having an RCA connector as a mating connector. However, the resulting excessive force is less likely to be transmitted to the soldered portions of the board, and the need for extra components such as leads, sockets, and plugs is eliminated, and the number of components can be reduced. It is an object of the present invention to provide a conversion connector which eliminates the need to form a connection piece for a lead wire at the terminal.

[0007]

According to the present invention, there is provided a conversion connector, wherein a first terminal unit having a first terminal to which a first terminal of the other party is electrically connected is different from the first terminal of the other party. The second terminal of the other side is electrically inserted and connected.
In a conversion connector in which a second terminal unit having a terminal and a board that electrically connects the first terminal and the second terminal are accommodated and fixed in a case, the second terminal unit includes: A body fixed to the case and the second terminal held by the body, wherein the second terminal is a plate-shaped contact piece protruding from the body; And a plate-shaped bridge portion extending in the direction opposite to the direction in which the contact piece protrudes, and a plate-shaped solder connected to the bridge portion and soldered to the substrate. And the bridge portion is capable of bending and deforming in the plate thickness direction on the contact piece side in a posture in which the plate width direction is orthogonal to a bent portion formed at an intermediate portion thereof. One piece part and a second piece part that can be bent and deformed in the thickness direction of the soldering part side And have, it is that divided into. In the present invention, it is preferable that both the first piece and the second piece of the bridge portion extend in the same direction.

[0008] In this conversion connector, the mating first terminal is electrically connected to the first terminal of the first terminal unit.
The counterpart second terminal is electrically connected to the second terminal of the terminal unit. Therefore, it is possible to electrically connect the other party's first terminal and the other party's second terminal, which are of different types, via this conversion connector. Specific examples of different types of the first terminal and the second terminal of the other party include a case where the first terminal of the other party is a terminal of an RGB connector and the second terminal of the other party is a terminal of an RCA connector. Can be.

In this conversion connector, the second terminal held by the body of the second terminal unit has a bridge portion between the contact piece and the soldered portion soldered to the board. Moreover, the bridge portion is divided into a first piece portion and a second piece portion that can be bent and deformed in the thickness direction in which the width direction of the bridge is orthogonal to the bent portion. Therefore, when a twisting force is applied to the contact piece,
The force is absorbed by the bending deformation of the first piece and the second piece, and the force is not easily applied to the soldered portion. In particular, the first
Since the one piece part and the second piece part are in a posture in which the plate width directions are orthogonal to each other, forces in two directions orthogonal to each other are absorbed by bending deformation of the first piece part and the second piece part. This is useful for remarkably exhibiting the effect of making the twisting force difficult to be transmitted to the soldered portion. Here, the “orthogonal posture” includes not only a posture that is exactly perpendicular, but also a cross posture that appears to be substantially perpendicular but not exactly perpendicular. That is, the first piece portion and the second piece portion intersect in the plate width direction such that forces in two directions orthogonal to each other are absorbed by the first piece portion or the second piece portion in the thickness direction of the bending deformation. This includes all postures you are doing.

In the present invention, it is desirable that the soldering portion bends at an opening angle orthogonal to the second piece portion, and that the bending portion bendably deform. With this configuration, when a force in the push-pull direction is applied to the contact piece, the force is absorbed by the bending deformation of the bent portion, and the force is not easily applied to the soldered portion. Become. Here, the “perpendicular opening angle” includes the case where the opening angles are exactly perpendicular to each other, as well as the opening angle where the apparent shape is almost perpendicular but not exactly perpendicular. Is also included. That is, it includes all the opening angles of the bent portion such that the force in the push-pull direction applied to the contact portion is absorbed by the bending deformation of the bent portion. Further, the shape of the bent portion may be a shape bent in an angular state or a shape curved in an arc shape.

In the present invention, the entirety of the soldering portion extends in a direction orthogonal to the projecting direction of the contact piece portion, and the tip of the soldering portion extends through a through hole formed in the substrate. It is desirable to be inserted and soldered to the board. In such a case, the tip of the soldering portion is positioned by the through hole of the substrate, so that the soldering portion does not easily move due to the above-described torsion force or the force in the push-pull direction, and the soldering portion cannot be moved. Hard force is hardly added.

Further, the conversion connector according to the present invention has a first terminal unit having a first terminal to which the first terminal of the other party is electrically connected, and a first terminal unit having a different type from the first terminal of the other party. A second terminal unit including a second terminal to which two terminals are electrically inserted and connected, and a substrate that electrically connects the first terminal and the second terminal are accommodated and fixed in a case. In the conversion connector, the second terminal unit includes a body fixed to the case and the second terminal held by the body, and the second terminal is a plate protruding from the body. A flaky contact portion, a bridge portion connected to the flank portion and extending in the direction opposite to the projecting direction of the flank portion and capable of bending and deforming in the plate thickness direction; and And soldered to the board Having a piece-shaped soldering portion, and bending at a boundary portion between the bridge portion and the soldering portion such that the plate width direction of the bridge portion and the plate width direction of the soldering portion are orthogonal to each other. Part is formed. In the present invention, it is desirable that the bridge portion and the soldering portion extend in the same direction.

In this conversion connector, the mating first terminal is electrically connected to the first terminal of the first terminal unit.
The counterpart second terminal is electrically connected to the second terminal of the terminal unit. Therefore, it is possible to electrically connect the other party's first terminal and the other party's second terminal, which are of different types, via this conversion connector. Specific examples of different types of the first terminal and the second terminal of the other party include a case where the first terminal of the other party is a terminal of an RGB connector and the second terminal of the other party is a terminal of an RCA connector. Can be.

In this conversion connector, the second terminal held by the body of the second terminal unit has a bridge portion at a portion between the contact piece and the soldered portion soldered to the board. Moreover, since the bent portion is formed at the boundary portion so that the plate width direction of the bridge portion and the plate width direction of the soldering portion are orthogonal to each other, a torsion force is applied to the contact piece portion. Sometimes, the force is absorbed by bending deformation of the bridge portion in the plate thickness direction, and the force is not easily applied to the soldered portion. Here, the “orthogonal posture” includes not only a posture that is exactly perpendicular, but also a cross posture that appears to be substantially perpendicular but not exactly perpendicular.

In the conversion connector according to each of the above-mentioned inventions, the second terminal is formed in a plate-shaped mounting portion inserted into a slit-shaped terminal mounting hole formed in the body, and the second terminal is cut and raised in the mounting portion. And a claw piece formed and locked to the hole wall of the mounting hole, and the contact piece portion and the bridge portion are distributed and integrated at the opposite end of the mounting portion. It is possible to adopt a configuration of being provided continuously. In this case, it is desirable that the slit-shaped terminal mounting hole be large enough to hold the plate-shaped mounting portion of the second terminal as little as possible. The transmission of the twisting force and the push-pull force applied to the one part to the bridge part is suppressed by the mounting part of the mounting part with respect to the terminal mounting hole, which is the transmission of the force to the soldering part. Helps to make it less likely to occur. Further, since the claw piece of the mounting portion is locked to the hole wall of the mounting hole, the removal of the second terminal from the body is prevented.

1 is a longitudinal sectional side view showing an embodiment of a conversion connector according to the present invention, FIG. 2 is a partially broken plan view of the conversion connector, and FIGS. 3 and 4 are used for the conversion connector. FIG. 4 is a schematic perspective view of two types of second terminals 21.
The conversion connector shown in FIGS. 1 and 2 includes a first terminal unit 10 capable of inserting and removing an RGB connector as a mating first terminal, and a second terminal unit 20 capable of inserting and removing an RCA connector as a mating second terminal. And a board (for example, a printed wiring board) 30.

The first terminal unit 10 is the same as the first terminal unit 10 employed in the conventional conversion unit described with reference to FIG. That is, a first terminal (none of which is shown in the figure) is held by an electrically insulating resin body, and a soldering portion 12 extending from the first terminal in a direction orthogonal to the first terminal is provided behind the resin body. The soldering portion 12 is provided and inserted into the through hole 32 of the board 30 and soldered to the conductor foil of the board 30. Further, a metal cap 13 is attached to the resin body, and the cap 13 functions as a ground contact piece. The first terminal unit 10 shown in the figure has a total of three terminal portions R, L, and V, one terminal portion used for video and two terminal portions used for audio. Each of R, L, and V has one of the first terminals.

The second terminal unit 20 includes a horizontally long resin body 23 having excellent electrical insulation and a second terminal 21 held by the body 23. And a metal rectangular cylindrical frame 24 surrounding the terminal 21. In the illustrated example, the required number of upper second terminals 21A, which are arranged and held in a horizontal line at an equal pitch on the upper portion of the body 23, and are arranged in a horizontal line at an equal pitch on the lower portion of the body 23. The required number of held lower second terminals 21B are distinguished, and the upper second terminals 21A and the lower second terminals 21B are arranged in a so-called staggered arrangement.

As shown in FIG. 3 and FIG.
Each of the second terminals 21 such as A and the lower second terminal 21 </ b> B is a plate-like mounting portion 25 and a contact piece portion which is distributed integrally to the opposite end of the mounting portion 25 and integrally provided. It is formed of a single metal plate having a bridge portion 27, a plate-like soldering portion 28 integrally connected to the bridge portion 27, and the like. And the claw piece 2 is attached to the mounting portion 25.
9 is cut and raised. In these second terminals 21, the contact piece 26 and the mounting part 25 are formed with bulging ribs 61, 62 long in the longitudinal direction.
Therefore, the rib portion 6 is provided between the contact piece portion 26 and the mounting portion 25.
1 and 62 impart the property of not easily bending and deforming. The bridge portion 27 is divided into a first piece portion 64 and a second piece portion 65 in which the plate width directions a and b are orthogonal to each other with a bent portion 63 formed at an intermediate portion thereof as a boundary. Since each of the first piece 64 and the second piece 65 is formed in a plate shape, the first piece 64 and the second piece 65 can easily bend and deform in the thickness direction. The first piece 64 and the second piece 65 extend in the same direction. Although the bent portion 63 in the illustrated example is bent at a right angle or a substantially right angle, this point may be bent in an arc shape, and such a bent portion 63 is bent so as to change its opening angle. Has the properties that are possible. The soldering portion 28 is
The bent portion 66 is bent at an opening angle θ orthogonal to the one-side portion 65, and has a property that the bent portion 66 can be flexibly deformed so as to change the opening angle θ. Bending part 6 in the example
Although 6 is bent in an arc shape, this point may be bent at a right angle or a substantially right angle. Of the second terminals 21, the upper second terminal 21A shown in FIG. 3 and the lower second terminal B shown in FIG. 4 differ only in the shape of the bridge portion 27, and the remaining portions have the same shape. Has become. The reason why the shape of the bridge portion 27 is different is that the arrangement position of the substrate 30 shown in FIGS.

The upper second terminal 21A and the lower second terminal 21B
As shown in FIGS. 1 and 2, the second terminal 21 is inserted into the slit-shaped terminal mounting hole 71 formed in the body 23 so that the second terminal 21 does not move as much as possible.
The claw piece 29 of the mounting portion 25 is engaged with a stepped hole wall 72 provided in the mounting hole 71. Therefore, RCA
Even if the second terminal 21 is pushed in the direction of the arrow P in FIG. 2 when the connector is inserted into the second terminal unit 20, no situation occurs such that the second terminal 21 comes out of the body 23. The second terminal 21 having the attachment portion 25 attached to the body 23 as described above has its contact piece portion 26 projecting into a space surrounded by a frame 24 in front of the body 23. The bridge portion 27 extends in a direction opposite to the direction in which the contact piece portion 26 protrudes, and the bent portion 63 and a part of the first piece portion 64 of the bridge portion 27 and the entirety of the second piece portion 65 are formed. Are disposed in the space S behind the body 23. The entire soldering portion 28 extends in a direction orthogonal to the direction in which the contact piece 26 protrudes, and the tip portion 28 a of the soldering portion 28 is inserted into a through hole 33 formed in the substrate 30. And soldered to the substrate 30. Reference numeral 34 denotes solder piled on the conductor foil of the substrate 30.

The first terminal unit 10, the second terminal unit 20, and the substrate 30 are housed in a case 40 formed by joining an upper case 41 and a lower case 42 formed in half. Fixed. This case 40 also serves as a handle. The substrate 30 has a substantially rectangular shape that is long on the left and right, and between the first terminal unit 10 and the second terminal unit 20 in the case 40.
They are arranged in a posture along their facing direction.

In the conversion connector described above, the second terminal unit 20 is a multi-pole terminal unit provided with more second terminals 26 than the number of poles of the first terminal of the first terminal unit 10. Then, as described above, the RGB connector as the mating first terminal is inserted into and pulled out of the first terminal unit 10, and the RCA connector as the mating second terminal is inserted into and pulled out of the second terminal unit 20.

In this conversion connector, when the RCA connector is inserted into or removed from the second terminal unit 20, or when the RCA connector is inserted into the second terminal unit 20, the upper second terminal 21A or the lower Although a prying force or a force in the push-pull direction may be applied to the contact piece 26 of the second terminal 21 such as the two terminals 21B, the force depends on the structure of the attachment portion with the bridge 27 or the body 23. It is difficult to transmit to the soldering portion between the soldering portion 28 and the board 30.

This point will be described with reference to FIGS.
When a torsion force is applied to the contact piece 26, the horizontal X-direction component of the force is absorbed by the bending deformation of the first piece 64 of the bridge 27 in the thickness direction (left-right direction in the drawing), and the force is applied. Is absorbed by the bending deformation of the second piece 65 of the bridge portion 27 in the thickness direction (vertical direction in the drawing). When a force in the push-pull direction is applied to the contact piece 26, the soldering part 28 and the second piece 6
5 is absorbed by being bent and deformed so as to change its opening angle θ. For this reason, it is difficult for a twisting force or a force in the push-pull direction to be applied to a soldering portion between the soldering portion 28 and the substrate 30. Such an effect is further enhanced by the fact that the attachment portion 25 is attached to the body 23 so as not to move as much as possible, that the tip portion 28a of the soldering portion 28 is positioned by the through hole 33 of the substrate 30, and the like. Prominently demonstrated.
Therefore, there is almost no possibility that a situation in which the conductor foil of the substrate 30 is peeled off due to excessive force applied to the soldered portion.

FIG. 5 is a vertical sectional side view showing another embodiment of the conversion connector according to the present invention, and FIG. 6 is a schematic perspective view of a second terminal 21 used in the conversion connector. The conversion connector shown in FIGS. 5 and 6 also has a first terminal unit 10 capable of inserting and removing an RGB connector as a mating first terminal,
A second terminal unit 20 and a board (for example, a printed wiring board) 3 into which an RCA connector as a counterpart second terminal can be inserted and removed.
0 is a conversion connector of a board connection type provided with 0.

The first terminal unit 10 has a configuration similar to the first terminal unit 10 described with reference to FIGS. The difference is that the soldering portion 14 extending rearward from the first terminal of the first terminal unit 10 is inserted into a through hole (not shown in the drawing) of the board 30 and soldered to the conductor foil of the board 30. That is the point. The first terminal unit 10 has a total of three terminal portions R, L, V similarly to the one shown in FIG. 2, and these terminal portions R, L, V
Have one first terminal.

With respect to the second terminal unit 20, only the structure of the bridge portion 27 and the soldering portion 28 of the second terminal 21 is different from that described with reference to FIGS.
The remaining structure is the same as that described with reference to FIGS. In other words, the bridge portion 27 is formed in a flat plate shape, and can be bent and deformed in the plate thickness direction. Further, a plate-like soldering portion 28 connected to the bridge portion 27 extends in the same direction as the bridge portion 27, and a plate between the plate width direction c of the bridge portion 27 and the soldering portion 28. A bent portion 67 is formed at the boundary between the bridge portion 27 and the soldering portion 28 so that the width direction d is perpendicular to the width direction d. Although the bent portion 67 in the illustrated example is bent at a right angle or a substantially right angle, this point may be bent in an arc shape.
It has the property that it can be bent and deformed to change its opening angle. The second terminal 21 is connected to the body 23
Are arranged in a staggered arrangement at an equal pitch on an upper portion and a lower portion.

The second terminal 21 has a mounting portion 25 whose body 2
3 is inserted into the slit-like terminal mounting hole 71 formed in the same manner as to move as little as possible.
9 is locked to a stepped hole wall (not shown) provided in the mounting hole 71, which is the same as that described in FIG. Therefore, even if the second terminal 21 is pushed in the direction of arrow P in FIG. 5 when the RCA connector is inserted into the second terminal unit 20,
Things don't happen like getting out of. The second terminal 2 having the mounting portion 25 mounted on the body 23 as described above
1 has a contact piece 26 projecting into a space surrounded by a frame 24 in front of a body 23. The bridge 27
Extends in the direction opposite to the direction in which the contact piece 26 protrudes, and a part of the bridge 27, the bent part 67, and the soldered part 28 are arranged in the space S behind the body 23. .
Further, a tip portion 28 a of the soldering portion 28 is inserted into a through hole 33 formed in the substrate 30 and soldered to the substrate 30. Reference numeral 34 denotes solder piled on the conductor foil of the substrate 30.

The first terminal unit 10, the second terminal unit 20, and the substrate 30 are housed in a case 40 formed by joining an upper case 41 and a lower case 42 formed in half. The point that the case 40 is fixed and the case 40 serves as a handle are the same as those described with reference to FIGS. 1 and 2. The substrate 30 has a substantially rectangular shape that is long on the left and right, and the first terminal unit 1
0 and the second terminal unit 20 are disposed in a posture orthogonal to their facing direction.

In the conversion connector described above, the second terminal unit 20 is a multi-pole terminal unit having the second terminals 26 having more poles than the first terminal of the first terminal unit 10. Then, as described above, the RGB connector as the mating first terminal is inserted into and pulled out of the first terminal unit 10, and the RCA connector as the mating second terminal is inserted into and pulled out of the second terminal unit 20.

In this conversion connector, when the RCA connector is inserted into or removed from the second terminal unit 20, or when the RCA connector is inserted into the second terminal unit 20, the upper second terminal 21A or the lower second terminal 21A is connected. Although a prying force or a force in the push-pull direction may be applied to the contact piece 26 of the second terminal 21 such as the two terminals 21B, the force depends on the structure of the attachment portion with the bridge 27 or the body 23. It is difficult to transmit to the soldering portion between the soldering portion 28 and the board 30.

This will be described with reference to FIG. When a twisting force is applied to the contact piece 26, the horizontal X
The directional component is absorbed by bending deformation of the bridge portion 27 in the thickness direction (the left-right direction in the figure). For this reason, a twisting force is less likely to be applied to a soldering portion between the soldering portion 28 and the board 30. Such an effect is more remarkable because the mounting portion 25 is mounted on the body 23 so as not to move as much as possible, and the tip portion 28a of the soldering portion 28 is positioned by the through hole of the substrate 30. It is exhibited in. Therefore, there is little possibility that a situation where the conductor foil of the substrate 30 is peeled off due to excessive force being applied to the soldered portion.

In each of the embodiments described above, the conversion connector in which the RGB connector is inserted and removed from the first terminal unit 10 and the RCA connector is inserted and removed from the second terminal unit 20 has been described. Such a conversion connector has two types of terminals, all of which are capable of electrically connecting different types of mating terminals to one terminal and the other terminal respectively. included. 1 to 6, the same or corresponding parts are denoted by the same reference numerals for convenience of explanation.

According to the present invention, it is possible to provide a conversion connector in which an excessive force is hardly transmitted to a soldered portion of a substrate and which does not require use of extra parts such as a lead wire, a socket, and a plug. become. Therefore, according to the present invention, the number of components can be reduced, and a conversion connector having excellent durability can be provided at low cost.
