Description

socket connector {SOCKET CONNECTOR}

The present invention relates to a socket connector. More specifically, the present invention relates to a socket connector including signal terminals having different positions of mounting parts.

In general, when substrates are interconnected, two connectors connected to each substrate by a method such as soldering are used, and the two connectors may be connected to each other. Here, one of the two connectors is a plug connector, and the other is a socket connector. A socket connector is also called a receptacle connector. Such a plug connector and a socket connector may be formed by disposing terminals in a mold part. A plug connector and a socket connector may be engaged with each other to form an electrical connector assembly.

In accordance with the trend of miniaturization of electronic devices, miniaturization and reduction in size of connectors are also required. However, there is a certain limit in reducing the pitch or reducing the size of the connector to reduce the size and height of the connector.

The technical problem to be solved by the present invention is to implement a lower height (reduction in length) of a connector without reducing a pitch or reducing components.

For example, in the conventional socket connector, it is common that all the mounting parts are arranged on the same line at regular intervals. The problem in that case is that the spacing between the mounting parts is made small in order to make the connector smaller (that is, to reduce the height). When the solder (solder) that attaches the mounting part to the board comes into contact with the adjacent mounting part. is that it occurs.

That is, the plurality of socket terminals (signal terminals) must be electrically insulated from each other so that desired signals can be distinguished and transmitted. However, if the distance (pitch) between the signal terminals is reduced in the process of reducing the connector size, as described above, in the process of mounting the connector on the board, some signal terminals may be electrically connected to each other undesirably. . This is because even if the signal terminals are precisely arranged at a small predetermined pitch, the solder may not be able to follow the precise pitch during the mounting process and the solder may spread undesirably.

The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the following description.

According to the present invention, there is provided a socket connector coupled to a plug connector, comprising: a base portion; a first wall portion protruding from an upper surface of the base portion; a second wall portion protruding from the upper surface of the base portion and intersecting the first wall portion; a third wall portion protruding from the upper surface of the base portion and intersecting the second wall portion and facing the first wall portion, a third wall portion projecting from the upper surface of the base portion and intersecting the first and third wall portions and facing the second wall portion 4 a mold part including a wall part; a bracket installed at least on the first wall portion; and a plurality of socket terminals installed at least on the second wall portion, wherein the plurality of socket terminals include a first type socket terminal and a second type socket terminal having different shapes, in the second wall portion, An imaginary line A connecting identical points of a mounting portion for mounting the first type socket terminal on a board, and an imaginary line connecting identical points of a mounting portion for mounting the second type socket terminal on the board B is provided with socket connectors that do not overlap each other and are parallel to each other.

Preferably, each of the plurality of socket terminals has an outer cut portion exposed from a sidewall of the mold portion, and the height of the outer cut portion of the first type socket terminal among the plurality of socket terminals is that of the second type socket terminal. It is higher than the height of the outer cut part, and higher than the surface of the base part of the said mold part.

Preferably, a side cross-section of the first type socket terminal is cut in a plane perpendicular to the longitudinal direction of the socket connector, and the second type socket terminal is cut in a plane perpendicular to the longitudinal direction of the socket connector. When viewed from a side cross-section, bending around the lower curved portion of the socket terminal of the first type is different from bending around the lower curved portion of the socket terminal of the second type, and the lower side of the socket terminal of the first type is different from bending around the lower curved portion of the socket terminal of the second type. The bending around the curved portion protrudes further downward than around the lower curved portion of the socket terminal of the second type, so that the periphery of the lower curved portion is exposed through a space cut out between the base portions of the mold portion.

Preferably, the mounting portion of the socket terminal of the second type is a flat surface or a curved surface adjacent to the outer cut portion of the socket terminal of the second type.

Preferably, the mounting portion of the socket terminal of the first type is spaced apart from the outer cut portion of the socket terminal of the first type.

Preferably, in the second wall portion, the first type socket terminal and the second type socket terminal are alternately arranged one by one.

Preferably, in the second wall portion, the first type socket terminal and the second type socket terminal are arranged in a mixture.

Preferably, the second socket terminal is further disposed on the fourth wall portion, and the arrangement state of the second socket terminal on the fourth wall portion is an arrangement state of the second socket terminal on the second wall portion is independent of

According to embodiments of the technical idea of the present invention, there are at least the following effects.

According to the present invention, the pitch of the second socket terminal 600 is the distance from the adjacent terminal, but when the second socket terminal 600 is viewed only by the same type, which mounting part ( 602A) and the distance between the adjacent mounting portions 602A is twice the pitch. Similarly, in the B-type terminal 600B, the distance between one mounting portion 602B and another adjacent positive portion 602B is twice the pitch.

That is, when the pitch between the second socket terminals 600 is m, the pitch between the mounting portions 602B of the B-type terminal 600B is 2m. Also in the A-type terminal 600A, the pitch between the mounting portions 602A is similarly set to 2 m.

And, since the mounting portion 602B of the B-type terminal 600B (directly adjacent to the outer cut-out 601B) and the outer cut-out 601A of the A-type terminal 600A have a height difference from each other, the B-type terminal 600B The fear that the solder (solder) to be used for the mounting portion 602B of the A-type terminal 600A is smeared or spread on other portions of the A-type terminal 600A (eg, the outer cut portion 601A, etc.) is significantly reduced.

If the solder cream or solder paste invades the side terminals, there is a problem that the terminals to be electrically separated are shorted. However, according to the present invention, the pitch between the plurality of second socket terminals 600 is narrow. However, since it is only necessary to consider the pitch of the terminals of the same type (ie, the A-type terminals 600A or the B-type terminals 600B), the concern can be greatly reduced. This is because there is a margin of space between the mounting parts.

In this way, while leaving the pitch between the second socket terminals 600 (eg, signal terminals) as it is, the pitch between the mounting parts can be virtually doubled, which is a great help in reducing the size of the connector. Since the pitch of the socket terminals 600 can be made close, the length direction of the connector as a whole can be reduced.

The effect according to the present invention is not limited by the contents exemplified above, and more various effects are included in the present specification.

Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in a variety of different forms, and only these embodiments allow the disclosure of the present invention to be complete, and common knowledge in the technical field to which the present invention belongs It is provided to fully inform the possessor of the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout.

1 is a view showing a socket connector 20 according to the present invention.

The socket connector 20 will be described as follows.

The socket connector 20 may include, for example, a socket mold part 400 , a first socket terminal 500 , and a second socket terminal 600 .

The socket mold part 400 (mold part of the socket connector) may have a shape accommodating the mold part (plug mold part) of the plug connector (not shown). For example, the mold part of the plug connector may have a shape to be inserted into a space defined by the mold part 400 of the socket connector.

The socket mold part 400 may be formed of an insulator including resin and epoxy, but is not limited thereto.

The first socket terminal 500 and the second socket terminal 600 may be disposed on the wall portion of the socket mold part 400 . In addition, the plurality of first socket terminals 500 and the plurality of second socket terminals 600 may be disposed on the wall portion of the socket mold part 400 .

Although only one first socket terminal 500 is shown in FIG. 1 , it is preferable that another first socket terminal 500 is formed on the wall facing each other in a symmetrical shape.

In addition, the socket mold part 400 has a base. The socket mold part 400 includes a base, a first wall part 110 protruding from the top surface of the base part, a second wall part 120 protruding from the top surface of the base part and intersecting the first wall part 110, and protruding from the top surface of the base part. a third wall portion (not shown) that intersects the second wall portion 120 and faces the first wall portion 110, protrudes from the upper surface of the base portion, intersects the first wall portion 110 and the third wall portion, and intersects the second wall portion ( and a fourth wall portion 140 opposite to the 120 .

For example, a first socket terminal 500 is formed on the first wall part 110, and a plurality of second socket terminals 600 are formed side by side on a second wall part 120 adjacent to the first wall part at about 90 degrees. , another first socket terminal 500 is formed on a third wall part (not shown) adjacent to the second wall part 120 at about 90 degrees, and a fourth adjacent to the third wall part (not shown) at about 90 degrees from the third wall part (not shown). A plurality of second socket terminals 600 are formed side by side on the wall portion 140 . Also, the fourth wall 140 and the first wall 110 are adjacent to each other at an angle of about 90 degrees.

Accordingly, the first wall part 110 and the third wall part (not shown) face each other and have a symmetrical shape, and the second wall part 120 and the fourth wall part 140 face each other and have a symmetrical shape.

The first socket terminal 500 and the second socket terminal 600 may include a conductive material.

For example, the first socket terminal 500 and the second socket terminal 600 may be formed of a metal material including copper, but is not limited thereto.

Accordingly, when the plug connector (not shown) is fastened to the socket connector 20 , the first plug terminal and the second plug terminal (not shown) are electrically connected to the first socket terminal 500 and the second socket terminal 600 . can be connected

For example, a first plug terminal (not shown) may be electrically connected to the first socket terminal 500 , and a second plug terminal (not shown) may be electrically connected to the second socket terminal 600 .

For example, when the first plug terminal is a power terminal, the first socket terminal 500 may input/output a power electrical signal. Depending on the situation, the first socket terminal 500 may be simply referred to as a metal ball, provided that no particular attention is paid to the fact that it is a power supply terminal and only the fact that a certain structure exists.

For example, when the second plug terminal is a signal terminal, the second socket terminal 600 may input/output an electrical data signal.

The socket connector 20 may be an exemplary socket connector to which a plug connector (not shown) according to an embodiment is fastened. The socket connector 20 may include, for example, a socket mold part 400 , a first socket terminal 500 , and a second socket terminal 600 .

The mold part 400 of the socket connector may have a shape to accommodate the mold part (plug mold part) of the plug connector (not shown). For example, the plug mold part may have a shape to be inserted into a space defined by the socket mold part 400 .

The socket mold part 400 may be formed of an insulator including resin and epoxy, but is not limited thereto.

The first socket terminal 500 and the second socket terminal 600 may be disposed on the wall portion of the socket mold part 400 . In addition, the plurality of first socket terminals 500 and the plurality of second socket terminals 600 may be disposed on the wall portion of the socket mold part 400 .

In the socket connector 20 of FIG. 1 , each of the first socket terminals 500 at both ends covers the plastic housing (the socket mold part 400 ). That is, there is no portion where the plastic housing covers the first socket terminal 500 , the first socket terminal 500 covers the plastic housing, and the first socket terminal 500 is exposed. As a conventional example, there is a case in which a portion of the first socket terminal 500 (eg, a portion corresponding to a corner portion of the socket connector 20) is covered with a plastic housing. Because the metal of the housing is completely covered, it prevents the housing from cracking and enables easier bonding operation.

On the other hand, as an example, the signal terminal as the second socket terminal 600 may be composed of 32 PINs that allow a current of 0.3A, and the power terminal as the first socket terminal 500 can allow a current of 5A have. The socket mold part 400 of the socket connector 20 is preferably made of a plastic material, and may be, for example, liquid crystal polymer (LCP). The first socket terminal 500 and the second socket terminal 600 of the socket connector 20 are preferably made of a metal, for example, gold plating (nickel underlayer) on copper alloy.

FIG. 2 shows the socket mold part 400 removed from FIG. 1 .

Although the first socket terminal 500 and the second socket terminal 600 should be fixed to the socket mold part 400 , in FIG. 2 , it is assumed that there is virtually no socket mold part 400 . Other than that, it is the same as FIG. 1 .

Although it can also be seen in FIG. 1 , what can be seen more clearly through FIG. 2 is that the heights of the outer cutouts 601A and 601B of the second socket terminal 600 are different depending on the type of the terminal 600 . That is, although it is commonly referred to as the second socket terminal 600 , referring to FIG. 2 , there is a terminal having a high outer cut-out portion 601A and a terminal having a low outer cut-out portion 601B. Higher height means that it is further in the +Z-axis direction in FIGS. 1 and 2 .

Referring back to FIG. 1 , although it is in contact with the socket mold part 400 , it can be seen that the high outer cut portion 601A and the low outer cut portion 601B are mixed.

FIG. 3 is an enlarged view of a part of FIG. 2 .

In FIG. 3 , similarly to FIG. 2 , the socket mold part 400 is conceptually deleted.

As shown in FIG. 3 , the high outer cut portion 601A and the lower outer cut portion 601B are mixed.

The second socket terminal 600 having the high outer cut portion 601A is referred to as an A-type terminal 600A, and the second socket terminal 600 having the lower outer cut-out portion 601B is referred to as the B-type terminal 600B. ) can be distinguished.

In the conventional socket connector, there is only one type of terminals corresponding to the second socket terminal of the present invention, and even if the shape is slightly different, as shown in FIG. 3 , two types of terminals having different heights of the outer cut portions 601A and 601B were not mixed.

4 is a view showing FIG. 3 in a different direction.

Also conceptually in FIG. 4 , the socket mold part 400 is deleted.

3 is a perspective view and FIG. 4 is also a perspective view, but it will be easily seen that the viewing direction is different. That is, FIG. 3 is a somewhat top-down view, and FIG. 4 is a somewhat bottom-up view.

In FIG. 3, in the A-type second socket terminal 600A and the B-type second socket terminal 600B, it has been described that the heights of the outer cutouts 601A and 601B are different. However, the A-type terminal 600A and the B-type terminal 600B are not only different in height of the outer cut portions 601A and 601B, but also have different positions of the mounting portions.

The mounting part refers to bonding a part of the second socket terminal 600 to the board by means of soldering or the like so that the second socket terminals 600 (600A, 600B) are fixed to the board.

As shown in FIG. 4 , the B-type second socket terminal 600B has a lower side immediately adjacent to the outer cutout 601B as a mounting portion 602B (hatched portion). However, in the A-type second socket terminal 601A, unlike that, the lower side immediately adjacent to the outer cutout 601A is not the mounting part, but the mounting part 602A that is more biased toward the center of the socket connector 20 (hatched part) exist separately.

That is, when viewed in FIG. 4 , a plurality of mounting units are not arranged in a line on one line in the X-axis direction, but a plurality of mounting units are arranged over two lines in the X direction.

Therefore, considering only the mounting portion 602A of the A-type terminal 600A, one line is formed sequentially at regular intervals in the X-axis direction, and only the mounting portion 602B of the B-type terminal 600B is considered. Another line is formed sequentially at regular intervals in the X-axis direction. That is, these two lines are parallel to each other. And the two lines are spaced apart from each other in the Y-axis direction. This will also be described later in FIG. 7 .

In a conventional socket connector, it is common that all mounting parts are arranged on the same line at regular intervals. The problem in that case is that when the spacing between mounting parts is made small in order to make the connector smaller (that is, to reduce the height), the solder (solder) that attaches the mounting part to the board comes into contact with the adjacent mounting part. is that it occurs.

That is, the plurality of socket terminals (signal terminals) must be electrically insulated from each other so that desired signals can be distinguished and transmitted. However, if the distance (pitch) between the signal terminals is reduced in the process of reducing the connector size, as described above, in the process of mounting the connector on the board, some signal terminals may be electrically connected to each other undesirably. will be This is because even if the signal terminals are precisely arranged to have a certain pitch, the solder may not be able to follow the precise pitch in the process of mounting on the board and the solder may spread undesirably.

However, referring to FIG. 4 , for example, when the pitch between the adjacent second socket terminals 600 is m, it can be easily seen that the pitch between the mounting parts of the second socket terminals 600 is 2m, not m. will be.

That is, according to the present invention, the pitch of the second socket terminal 600 is the distance from the adjacent terminal, but the distance between one mounting part 602A and another mounting part 602A adjacent to it is twice the pitch.

And the distance between one mounting part 602B and another mounting part 602B also becomes twice the said pitch.

If the solder cream or solder paste invades the side terminals, there is a problem that the terminals to be electrically separated are shorted. However, according to the present invention, the pitch between the plurality of second socket terminals 600 is narrow. However, since it is only necessary to consider the pitch of the terminals of the same type (ie, the A-type terminals 600A or the B-type terminals 600B), the concern can be greatly reduced. This is because there is a margin of space between the mounting parts.

1 to 4, when the A-type terminal 600A and the B-type terminal 600B are alternately arranged, the outer cutout 601A of the A-type terminal and the outer cutout 601B of the B-type terminal are different in height And, it is only the B-type terminal 600B that the mounting portion is formed adjacent to the outer cutout. As shown in FIG. 4 , the A-type terminal 600A is not a surface adjacent to the outer cutout, but a hatched portion 602A spaced a predetermined distance from it in the Y-axis direction is the mounting portion.

Then, assuming that the pitch of the second socket terminals 600 is m, the pitch of the mounting parts 602B of the B-type terminal 600B is 2m. Also in the A-type terminal 600A, the pitch between the mounting portions 602A is similarly set to 2 m.

And, since the mounting portion 602B of the B-type terminal 600B (directly adjacent to the outer cut-out 601B) and the outer cut-out 601A of the A-type terminal 600A have a height difference from each other, the B-type terminal 600B The fear that the solder (solder) to be used for the mounting portion 602B of the A-type terminal 600A is smeared or spread on other portions of the A-type terminal 600A (eg, the outer cut portion 601A, etc.) is significantly reduced. This height difference can be clearly seen in FIG. 3 .

Meanwhile, in FIG. 4 , the mounting portion 602A of the A-type terminal 600A may be viewed as being at the same height as a member immediately next to it (next to the X-axis direction). However, the arc shape when the vicinity of the mounting portion 602A of the A-type terminal 600A is cut in the YZ plane (that is, a plane orthogonal to the X-axis) and the inner side (BB; lower curved portion) of the B-type terminal 600B are YZ The arch shape when cut in a plane is shown somewhat differently in FIG. 4 .

Due to such a difference, when viewed from the bottom as shown in FIG. 5 to be described later, the mounting portion 602A of the A-type terminal 600A is exposed, and the inner portion of the B-type terminal (BB; see FIG. 4) is a socket mold portion ( 400), so it is not visible. That is, whether the socket mold part 400 is covered is different.

5 is a perspective view of the socket connector 20 of the present invention as viewed obliquely from the bottom.

In FIG. 5 , it can be seen that the mounting portion 602A of the A-type terminal 600A is exposed, and the inner portion BB of the B-type terminal (refer to FIG. 4 ) is hidden by the socket mold portion 400 . In FIG. 4 , the arch shape when the vicinity of the mounting portion 602A of the A-type terminal is cut in the YZ plane and the arch shape when the inner portion BB of the B-type terminal is cut in the YZ plane are shown to be slightly different. If the arch shape is so different, as shown in FIG. 5 , the inner part BB of the B-type terminal 600B is covered by the socket mold part 400 , and the mounting part 602A of the A-type terminal 600A is easily exposed. Do.

However, it is not limited thereto, and the arch shape when the vicinity of the mounting part 602A of the A-type terminal is cut in the YZ plane and the arch shape when the inner part (BB) of the B-type terminal is cut in the YZ plane is not different. Depending on the shape of the socket mold part 400 , the inner part BB of the B-type terminal may be covered by the socket mold part 400 and the mounting part 602A of the A-type terminal may be exposed.

In the above example, it has been described that the A-type second socket terminals 600A and B-type second socket terminals 600B are alternately arranged one by one. Although this example is preferred, the present invention is not limited thereto.

That is, the A-type terminal 600A, the B-type terminal 600B, the A-type terminal 600A, the B-type terminal 600B, ... are arranged side by side in this order to effectively double the pitch between the mounting parts. It is preferable in terms of being able to increase and the ease of molding the socket mold part 400, but it is not necessarily limited thereto.

For example, the sequence of the A-type terminal 600A, the B-type terminal 600B, the B-type terminal 600B, ... may be repeated. Alternatively, the sequence of the A-type terminal 600A, the A-type terminal 600A, the B-type terminal 600B, ... may be repeated.

Alternatively, it is also possible that they are mixed without a specific rule.

Alternatively, in a certain section, the A-type terminal 600A, the B-type terminal 600B, the B-type terminal 600B, ... is repeated in the order, and the edge of the second socket terminal 600 (ie, the first socket) is repeated. It is also possible to arrange in a different manner only in the portion close to the terminal 500 .

As described above, the arrangement order of the A-type terminals 600A and B-type terminals 600B is not limited. The reason is that the A-type terminal 600A, the B-type terminal 600B, the A-type terminal 600A, the B-type terminal 600B, ... are arranged side by side in this order to effectively increase the pitch between the mounting parts. Although it is the most efficient in that it can be doubled, even if it is not the entire section, if the pitch is increased in some sections, the mounting efficiency increases as much.

6 is a side cross-sectional view of an A-type terminal 600A and a B-type terminal 600B.

A side cross-section of the first type socket terminal 600A cut in a plane (YZ plane) orthogonal to the longitudinal direction (X-axis direction) of the socket connector 20 is shown in FIG. 6A .

Similarly, a side cross-section of the second type socket terminal 600B cut in a plane (YZ plane) orthogonal to the longitudinal direction (X-axis direction) of the socket connector 20 is shown in FIG. 6B .

Although it can also be seen in FIG. 4 , as is more clearly seen in FIG. 6 , bending around the lower curved portion of the A-type socket terminal 600A (square dotted line) and the B-type socket terminal 600B around the lower curved portion (square) The bending of the dotted line) is different.

Specifically, the bending around the lower curved portion of the A-type socket terminal 600A protrudes further downward than around the lower curved portion of the B-type socket terminal 600B, so that the lower curved portion around the socket molded portion ( 400) is easily exposed through the space cut out between the bases.

This can also be seen from FIG. 6 , and also from FIG. 5 viewed obliquely from the bottom. It turns out that the periphery of the lower curved part (around the mounting part 602A) shown by the square dotted line of Fig.6 (a) is exposed in FIG.

Although the difference in the bending state around the lower curved part (square dotted line) shown in FIGS. 6(a) and 6(b) is not essential, it is bent as shown in FIGS. 6(a) and 6(b). If present, the mounting portion 602A of the A-type terminal 600A is exposed to the space between the bases of the socket molded portion 400 , and the lower curved portion BB of the B-type terminal 600B is located at the base of the socket molded portion 400 . It is easier to make it covered by

7 is the same view as that of FIG. 4, but is illustrated again with attention to the arrangement of the mounting unit.

When the center points of the mounting portion 602A of the A-type terminal 600A are connected to each other, a single line is formed. This is indicated by line A in FIG. 7 .

In addition, when the center points of the mounting portion 602B of the B-type terminal 600B are connected to each other, another line is formed. This is indicated by line B in FIG. 7 .

Line A and line B do not overlap and are parallel.

The center point may be a center of gravity or an area center. However, although it is said that the center points are connected, this center point does not have to be the center of gravity in the strict sense or the center of the area in the strict sense. That is, it is the same even if a specific point of the mounting part 602A of 600A of A-type terminals is selected and the said selected specific point is connected in some A-type terminal 600A arrange|positioned. The same is true for the B-type terminal 600B.

For example, in FIG. 7 , line B was obtained by selecting and connecting the center of the plurality of mounting units 602B in terms of area or weight, but positions corresponding to each other in the plurality of mounting units 602B (eg, the left side in FIG. 7 ). upper corner point), it can be seen that a new line B parallel to line A is obtained even if the corresponding points are connected. In other words, an imaginary line A connected to the same points of the plurality of mounting units 602A for mounting the A-type socket terminal 600A on the board and the B-type socket terminal 600B are mounted on the board. It may be said that the imaginary line B connected to the same points of the plurality of mounting units 602B to be described is parallel to each other without overlapping each other.

At this time, since the A-type terminals 600A and B-type terminals 600B are alternately arranged, the plurality of second socket terminals 600 (A-type terminals 600A and B-type terminals 600B) are connected to each other. When the pitch of the A-type terminal 600A is m, the pitch between the mounting parts 602A of the A-type terminal 600A is 2m, and the pitch between the mounting parts 602B of the B-type terminal 600B is also 2m. You will be able to easily figure out what this is going to be.

The illustration of FIG. 7 shows a part of the 2nd wall part 120 in FIG. However, as an example, the fourth wall portion 140 in FIG. 1 may also be formed symmetrically.

Of course, various modifications may be made. For example, even if the A-type terminal 600A and the B-type terminal 600B are alternately disposed on the second wall part 120 as shown in FIG. 7 , the fourth wall part 140 facing it is disposed differently (for example, , it is also possible to arrange only the B type terminals).

Alternatively, even if the terminals 600A and 600B are mixed without a certain rule, the line A connecting the mounting units 602A and the line B connecting the mounting units 602B form separate parallel lines that do not overlap each other. The point will not change.

Of course, in terms of efficiency, the form shown in FIG. 7 would be the best, but even if some of the second socket terminals 600 deviate from the rule, the effect of increasing the pitch between the mounting parts is generally exhibited.

8 is a view of the diagram of FIG. 7 viewed from another perspective.

It can be seen that when the mounting parts of the adjacent second socket terminals 600 are connected to each other in FIG. 7 or 8 , a zigzag (cheonjo (千鳥)) shape is obtained. If the A-type terminals 600A and B-type terminals 600B are alternately arranged one by one, an accurate zigzag arrangement will be obtained.

This is a different expression of what has been described in FIG. 7 . Due to this zigzag arrangement, the pitch between the socket terminals 600A or 600B of the same type is doubled compared to the pitch between the plurality of second socket terminals 600 .

However, as described above, the arrangement may be slightly changed. That is, if the A-type terminal 600A and the B-type terminal 600B are alternately arranged one by one, an accurate zigzag arrangement will be obtained, but the order of the terminals 600A, 600A, 600B, ... Even if it is repeatedly arranged with , an approximate zigzag arrangement is obtained even if not an exact zigzag arrangement.

Alternatively, even if the terminals 600A and 600B are mixed without a certain rule, it may also be said to be an approximate zigzag arrangement, even if it is not an exact zigzag arrangement. Of course, in terms of efficiency, the form shown in FIGS. 7 and 8 would be best, but even if some of the second socket terminals 600 deviate from the rule, the effect of increasing the pitch between the mounting parts is generally exhibited.

On the other hand, although the arrangement in the second wall part 120 has been mainly described, the arrangement in the fourth wall part 140 is the same. That is, it is common that the second socket terminal 600 is additionally disposed on the fourth wall portion 140 . Most preferably, the A-type terminals 600A and B-type terminals 600B are alternately arranged one by one in the second wall portion 120 and the fourth wall portion 140 . In this case, referring to FIG. 7 , lines A and B are present for the second wall part 120 , and lines A' (not shown) and line B' (not shown) exist with respect to the fourth wall part 140 . Thus, there will be four parallel lines (line A, line B, line A', line B').

However, the present invention is not limited thereto, and the arrangement state of the second socket terminals 600 ( 600A and 600B) in the fourth wall part 140 is, the second socket terminals 600 ; 600A, 600B in the second wall part 120 . ) can be independent of the arrangement state. That is, in the second wall portion 120 , the terminals 600A and 600B are alternately disposed one by one, and in the fourth wall portion 140 , only the terminals 600A exist, and various modifications are possible.

In addition, although the A-type terminal 600A and the B-type terminal 600B have been described, it may be assumed that a C-type terminal having another shape having a different mounting position is also present. Of course, in consideration of ease of manufacture and ease of arrangement, it is most preferable to alternately arrange A-type terminals 600A and B-type terminals 600B one by one, but the present invention provides another third type (eg, C type) terminals are also not excluded.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without changing the technical spirit or essential features of the present invention. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
