[The problem to be solved by the invention]

In order to support the miniaturization and high functionality of mobile phones, PCs (Personal Computers), tablet computers, etc., multi-pole connectors for high-frequency applications need to be further miniaturized. In the connector of Patent Document 1, since the insulating member has a side wall portion surrounding the center portion, there is a problem that the lateral size becomes larger. Assuming that the side wall is removed and the center is left, the arrangement direction of the connector on the inner terminal becomes longer, and if a force is applied to the connector, it is easy to bend. If the connector is bent, the strength is insufficient and it may break. In order to make up for the lack of strength, for example, if the width of the internal terminal is increased, the signal flow path will become longer, the signal loss will increase, or the impedance will deviate, and the VSWR characteristic may be degraded.

Therefore, the object of the present invention is to provide a male connector that can achieve both miniaturization and high strength. [Technical means to solve the problem]

In order to achieve the above object, the male connector of the present invention includes: a plurality of internal terminals arranged in a single row; and an insulating member for holding the plurality of internal terminals electrically insulated from each other, and the insulating member has at least one A box-shaped shape with an open direction, and as four sidewalls, there are first and second sidewalls facing each other and extending in the longitudinal direction and parallel, and third and second facing each other and extending in the short-side direction. 4 side wall portions, the first side wall portion has a holding portion that holds the plurality of internal terminals arranged in a single row.

Hereinafter, the embodiments of the present invention will be described in detail based on the drawings.

(Implementation form) Fig. 1 is a perspective view showing the connector set 2 of the embodiment. As shown in FIG. 1, the connector group 2 has the male connector 4 which is a 1st connector, and the female connector 6 which is a 2nd connector. The male connector 4 and the female connector 6 are fitted to each other to form a connector group 2.

The male connector 4 and the female connector 6 are mounted on each circuit board (not shown). The male connector 4 is mounted on a first circuit board (not shown), and the female connector 6 is mounted on a second circuit board (not shown). In particular, the first circuit board on which the male connector 4 is mounted is a flexible board.

Figures 2A-2C show the male connector 4. 2A is a perspective view of the male connector 4, FIG. 2B is an exploded perspective view of the male connector 4, and FIG. 2C is a top view of the male connector 4. The orientation of the male connector 4 shown in FIGS. 2A-2C and the orientation of the male connector 4 shown in FIG. 1 are reversed up and down.

As shown in FIGS. 2A to 2C, the male connector 4 includes an internal terminal 8, an external terminal 10 and an insulating member 12. The male connector 4 has a long-side direction and a short-side direction, and the long-side direction is referred to as the A direction, and the short-side direction is referred to as the B direction. The vertical direction orthogonal to both the long-side direction and the short-side direction is referred to as the C direction.

The internal terminal 8 is a terminal that is fitted and electrically connected to the internal terminal 20 (FIG. 3A, etc.) of the female connector 6 described later. A plurality of internal terminals 8 are provided, and they are arranged along the A direction of the longitudinal direction. The rows of internal terminals 8 in the embodiment are not plural rows, but a single row with only one row.

Each of the internal terminals 8 has a fastening portion 8A that is fastened to the insulating member 12, and a mounting portion 8B extending from the fastening portion 8A. The mounting portion 8B is a portion mounted on the above-mentioned first circuit board (not shown). Each of the mounting portions 8B extends in the B1 direction in the short-side direction, that is, the B direction.

The internal terminals 8 have the same shape and size. Each of the internal terminals 8 is formed of the same conductive material (for example, phosphor bronze).

The external terminal 10 is a terminal that is fitted and electrically connected to the external terminal 22 (FIG. 3A, etc.) of the female connector 6 described later. In the embodiment, two external terminals 10 are provided, and the first external terminal 10A and the second external terminal 10B are provided. The first external terminal 10A and the second external terminal 10B are terminals of different members independent of each other, and are provided at positions facing each other in the A direction.

As with the internal terminal 8, each of the external terminals 10 has the same shape and size. Each of the external terminals 10 is formed of the same conductive material (for example, phosphor bronze).

The insulating member 12 is a member that holds the internal terminal 8 and the external terminal 10 in a state of being electrically insulated from each other. The insulating member 12 is formed of resin that is an insulating material (for example, liquid crystal polymer).

As shown in FIG. 2B, the insulating member 12 has a box shape opened in the C1 direction, which is one of the C directions (the upper direction in this embodiment). The insulating member 12 includes four side wall portions 14A, 14B, 14C, and 14D and a bottom portion 16.

The four side wall portions 14A-14D are side wall portions that are continuously connected to form a space inside. As the four side wall portions 14A-14D, a first side wall portion 14A, a second side wall portion 14B, a third side wall portion 14C, and a fourth side wall portion 14D are provided.

The first side wall portion 14A and the second side wall portion 14B are provided at side wall portions facing each other, and extend in the A direction of the longitudinal direction. The third side wall portion 14C and the fourth side wall portion 14D are provided at side wall portions facing each other, and extend in the B direction of the short side direction.

The first side wall portion 14A holds a plurality of internal terminals 8. The first side wall portion 14A is provided with a recess 18 for fitting and engaging the engaging portion 8A of the internal terminal 8. The recessed portion 18 functions as a holding portion for holding the internal terminal 8. The holding portion is not limited to the recessed portion 18, and any form (concave and convex, etc.) may be used as long as it can hold the internal terminal 8. Since the first side wall portion 14A has the recessed portion 18, when the male connector 4 is bent and flexed in the C direction of the vertical direction, a place where stress is likely to be concentrated.

The second side wall portion 14B is provided in parallel with the first side wall portion 14A. The second side wall portion 14B is formed to run parallel to the first side wall portion 14A. The second side wall portion 14B of the embodiment extends in the same A direction as the first side wall portion 14A, and is parallel to the first side wall portion 14A. In the second side wall portion 14B, the recessed portion 18 is not provided as in the first side wall portion 14A, and the top surface of the second side wall portion 14B is formed flat except for the portion where the external terminal 10 is held.

Since the second side wall portion 14B is formed in parallel with the first side wall portion 14A, when the male connector 4 is bent and flexed in the C direction, the stress generated in the first side wall portion 14A and the second side wall portion 14B can be equalized To disperse. Thereby, it is possible to prevent stress from being concentrated on the first side wall portion 14A in particular, and it is possible to increase the strength of the male connector 4.

The third side wall portion 14C holds the first external terminal 10A. The fourth side wall portion 14D holds the second external terminal 10B. These external terminals 10 have a function of attracting (guidance) when the male connector 4 and the female connector 6 are fitted to each other, and a function of being a ground terminal.

In addition to the third side wall portion 14C, the first external terminal 10A also spans the corners of the first side wall portion 14A and the second side wall portion 14B. In addition to the fourth side wall portion 14D, the second external terminal 10B also straddles the corner portions on the other side of the first side wall portion 14A and the second side wall portion 14B.

In the first side wall portion 14A, a recessed portion 18 for holding a plurality of internal terminals 8 is formed at a portion other than the corner portion spanned by the first external terminal 10A and the second external terminal 10B.

In the second side wall portion 14B, portions other than the corner portions spanned by the first external terminal 10A and the second external terminal 10B are formed with a flat top surface, and no recesses are formed.

The bottom part 16 is a part supporting the four side wall parts 14A-14D. By providing the bottom portion 16, the insulating member 12 has a box-like shape that is open in only one direction of the C1 direction out of the six directions of the A direction, the B direction, and the C direction. According to this structure, the strength of the male connector 4 can be improved compared to the case where the bottom 16 is not provided, that is, the box type is opened in two directions of the upper direction and the lower direction.

As described above, the male connector 4 of the embodiment includes a plurality of internal terminals 8 arranged in a single row, and an insulating member 12 that holds the plurality of internal terminals 8 in a state of being electrically insulated from each other. The insulating member 12 has a box shape open in the upper direction C1, and has four side wall portions 14A-14D. The four side wall portions 14A-14D include: a first side wall portion 14A and a second side wall portion 14B facing each other and extending in the A direction of the longitudinal direction and parallel; and facing each other and extending in the B direction of the short side direction The third side wall portion 14C and the fourth side wall portion 14D. The first side wall portion 14A has a concave portion 18 that holds a plurality of internal terminals 8 arranged in a single row.

In this way, in the case of the male connector 4 in which a plurality of internal terminals 8 are arranged in a single row, since the arrangement direction of the internal terminals 8, that is, the A direction becomes longer, the connector as a whole tends to bend. On the other hand, by making the insulating member 12 into a box shape having four side wall portions 14, the force applied to the male connector 4 can be dispersed, and the strength of the male connector 4 can be increased.

When the male connector 4 is mounted on the first circuit board, the male connector 4 is sucked by a suction nozzle (not shown), and the male connector 4 is transported to the first circuit board. When the male connector 4 is mounted on the first circuit board, it is easy to bend in the vertical direction. In addition, after the male connector 4 is mounted on the first circuit board, when the male connector 4 is fitted to the female connector 6 and when the fitting is released, it is easy to bend in the vertical direction. In particular, since the first circuit board is a flexible board, it is easy to bend in the vertical direction. In contrast, according to the configuration of the male connector 4 as described above, by making the insulating member 12 into a box shape, the effect of reinforcing the strength of the male connector 4 can be more effectively exhibited.

Furthermore, in the male connector 4 of the embodiment, the internal terminal 8 is held by the first side wall portion 14A of the insulating member 12. Therefore, compared with the case where a row for holding the internal terminal 8 is additionally provided in the inner space of the side wall portions 14A-14D, the size in the lateral direction can be reduced. In this way, the size of the male connector 4 can be reduced.

In addition, since the first side wall portion 14A has the recessed portion 18 for holding the internal terminal 8, the stress concentration is likely to occur. However, the second side wall portion 14B facing the first side wall portion 14A is formed in parallel with the first side wall portion 14A. Trip. By providing such a second side wall portion 14B, the stress generated when the male connector 4 is flexed can be evenly distributed in the first side wall portion 14A and the second side wall portion 14B, and in particular, the concentration of stress on the first side wall portion 14A can be suppressed . In this way, the strength of the male connector 4 can be increased.

In addition, the male connector 4 of the embodiment further includes an external terminal 10, and the external terminal 10 has a first external terminal 10A and a second external terminal 10B that are different members from each other. The third side wall portion 14C holds the first external terminal 10A, and the fourth side wall portion 14D holds the second external terminal 10B. In this way, by providing two external terminals, which are respectively held in the third side wall portion 14C and the fourth side wall portion 14D which are different from the first side wall portion 14A holding the internal terminal 8, the effective arrangement can be achieved.

In addition, according to the male connector 4 of the embodiment, each of the internal terminals 8 has an engaging portion 8A engaging with the recess 18 of the first side wall portion 14A, and a mounting portion 8B extending from the engaging portion 8A. The extending direction of the mounting portion 8B is toward the B1 direction on the side opposite to the side where the first side wall portion 14A and the second side wall portion 14B are located. According to this structure, when designing the insulating member 12, the shape of the mounting portion 8B can be as free as possible.

Furthermore, according to the male connector 4 of the embodiment, the insulating member 12 is made of resin, and the second side wall portion 14B is formed to include only the resin. With such a configuration, the insulating member 12 can be produced at a low cost, and the reinforcing structure for the second side wall portion 14B can also be produced at a low cost.

Moreover, according to the male connector 4 of the embodiment, the top surface of the second side wall portion 14B is flat. According to such a structure, compared with the shape with the recessed part 18 like the 1st side wall part 14A, the part where stress is easy to concentrate is hard to generate|occur|produce, and the male connector 4 can be further increased in strength.

In addition, in the above-mentioned embodiment, the case where both the internal terminal 8 and the external terminal 10 are provided was demonstrated, but it is not limited to this case. It may also be a case where the external terminal 10 is not provided, and only the internal terminal 8 is provided. In addition, in the embodiment, the case where the first side wall portion 14A and the second side wall portion 14B are parallel to each other has been described, but it is not limited to this case. It may not be parallel, as long as they are parallel. In addition, in the embodiment, the case where the insulating member 12 is opened only in the upward direction, that is, in the C1 direction, has been described, but it is not limited to this case. By not providing the bottom 16, the lower part of the insulating member 12 is also opened, and both upper and lower parts are opened. That is, the insulating member 12 only needs to have four side wall portions 14A-14D and be open in at least one direction.

Next, Figures 3A-3C show the female connector 6. 3A is a perspective view of the female connector 6, FIG. 3B is an exploded perspective view of the female connector 6, and FIG. 3C is a top view of the female connector 6. The orientation of the female connector 6 shown in FIGS. 3A to 3C is the same as the orientation of the female connector 6 shown in FIG. 1.

As shown in FIGS. 3A to 3C, the female connector 6 includes an internal terminal 20, an external terminal 22 and an insulating member 24. The female connector 6 has a long side direction and a short side direction, and let the long side direction be the D direction, and let the short side direction be the E direction. The vertical direction orthogonal to both the long-side direction and the short-side direction is referred to as the F direction. In addition, the D direction, the E direction, and the F direction correspond to the A direction, the B direction, and the C direction of the male connector 4, respectively.

The internal terminal 20 is a terminal that is fitted and electrically connected to the internal terminal 8 of the male connector 4 (FIG. 2A, etc.). A plurality of internal terminals 20 are provided, and they are arranged along the D direction of the longitudinal direction. The rows of the internal terminals 20 in the embodiment are not plural rows, but a single row with only one row.

The shape and size of each of the internal terminals 20 are the same, and they are formed of the same conductive material (for example, phosphor bronze).

The external terminal 22 is a terminal that is fitted and electrically connected to the external terminal 10 of the male connector 4 (FIG. 2A, etc.). As shown in FIG. 3B etc., the external terminal 22 of an embodiment is provided as a single ring-shaped member, but it may be divided, and it is not limited to a single ring-shaped member.

The insulating member 24 is a member that holds the internal terminal 20 and the external terminal 22 in a state of being electrically insulated from each other. The insulating member 24 is formed of resin that is an insulating material (for example, liquid crystal polymer).

In this configuration, as shown in FIG. 3B, two internal terminals 20A and 20B are located at the end of the arrangement direction in the D direction among the plurality of internal terminals 20. The end internal terminal (first internal terminal) 20A is an internal terminal located on one side of the D direction, and the end internal terminal (second internal terminal) 20B is an internal terminal located on the other side of the D direction. Between the internal terminal 20A of the end and the internal terminal 20B of the end, a plurality of internal terminals (third internal terminals) 20C are provided as internal terminals 20 other than the end.

When a high-frequency signal flows through the connector set 2, it is easy to generate impedance deviations between the internal terminals 20A and 20B of the terminals and the internal terminals 20C other than the terminals. In particular, when the internal terminals 20A and 20B of the ends are not set as terminals connected to the ground, but are set as signal terminals, the internal terminals 20A and 20B of the ends are not clamped by the internal terminal 20 connected to the ground. There is an impedance deviation between the internal terminals 20C other than the terminal.

In addition, the inner terminals 20A and 20B located at the outermost ends of the plurality of inner terminals 20 are sandwiched by the adjacent inner terminal 20C and the outer terminal 22. In order for the external terminal 22 to have the attracting function of the male connector 4, which is the mating connector, the shape is limited, and the distance between the internal terminals 20A and 20B and the facing area cannot be freely designed. Therefore, the difference between the impedance of the internal terminals 20A and 20B and the impedance of the other internal terminals 20C becomes a problem.

In contrast, the female connector 6 of the embodiment is further provided with an impedance adjustment terminal 26. The impedance adjustment terminal 26 is a terminal used to adjust the impedance of the internal terminals 20A and 20B of the end to be close to the impedance of the internal terminal 20C other than the end. The impedance adjustment terminal 26 is independent of the plurality of internal terminals 20, and is arranged at the positions of the internal terminals 20A and 20B at the edge. By providing the impedance adjustment terminal 26, the impedance of the internal terminals 20A and 20B of the end can be close to the impedance of the internal terminal 20C outside the end, and the impedance deviation can be suppressed. The impedance adjustment terminal 26 may be connected to the ground or not connected. In addition, when the impedance adjustment terminal 26 is connected to the ground, the impedance of the internal terminals 20A and 20B of the end can be greatly adjusted.

When the impedance adjustment terminal 26 is arranged at the position of the internal terminals 20A, 20B along the edge, if it is a position where the impedance of the internal terminals 20A, 20B of the end can be changed, it can also be arranged at any position.

In the embodiment, in particular, two impedance adjustment terminals 26 are provided. The impedance adjustment terminal 26 includes a first impedance adjustment terminal 26A and a second impedance adjustment terminal 26B.

The first impedance adjustment terminal 26A corresponds to the internal terminal 20A of the end, and is arranged at a position adjacent to the internal terminal 20A of the end. The second impedance adjustment terminal 26B corresponds to the internal terminal 20B of the end, and is arranged at a position adjacent to the internal terminal 20B of the end.

FIG. 4 takes the first impedance adjustment terminal 26A and the internal terminal 20A of the end as an example, and shows a perspective view showing the relationship between them. 4 is a perspective view showing the first impedance adjustment terminal 26A, the internal terminal 20A of the end, and the internal terminal 20C adjacent to the internal terminal 20A of the end.

As shown in FIG. 4, the first impedance adjustment terminal 26A is opposed to the internal terminal 20A at the end in the D direction of the arrangement direction of the internal terminals 20. When viewed from the direction D, the first impedance adjustment terminal 26A and the internal terminal 20A of the end are opposed to each other in a partially overlapping manner. On the side surface 28 of the inner terminal 20A at the end, the area facing the first impedance adjustment terminal 26A is set as an opposing area 29. The facing area 29 is a partial area with respect to the entire area of the side surface 28.

The first impedance adjustment terminal 26A is arranged with a distance D1 in the D direction relative to the internal terminal 20A at the end. The distance D1 is the shortest distance between the first impedance adjustment terminal 26A and the inner terminal 20A of the end.

In this configuration, by changing the position of the first impedance adjustment terminal 26A in the D direction, the distance D1 between the first impedance adjustment terminal 26A and the internal terminal 20A of the end can be changed. Thereby, the impedance value of the internal terminal 20A of the end can be changed. Furthermore, by changing the shape of the first impedance adjustment terminal 26A, the area of the facing region 29 of the internal terminal 20A facing the end of the first impedance adjustment terminal 26A can be changed. Thereby, the impedance value of the internal terminal 20A of the end can be changed.

In this way, by changing the distance D1 and the area of the facing region 29, the impedance of the internal terminal 20A of the end can be adjusted to various values. Since the first impedance adjustment terminal 26A and the plurality of internal terminals 20 are provided independently, its position and shape can be changed variously, and the impedance of the internal terminal 20 can be set to a more desired value.

In particular, in the embodiment, the distance D1 between the first impedance adjustment terminal 26A and the internal terminal 20A of the end is set to be the distance D2 or less that is the distance between the internal terminals 20. According to this structure, the influence of the first impedance adjustment terminal 26A on the impedance of the end internal terminal 20A becomes greater, and the impedance adjustment of the end internal terminal 20A can be performed more easily.

As shown in FIG. 4, the first impedance adjustment terminal 26A has a different shape and a different size from the plurality of internal terminals 20. According to this structure, the shape and size of the first impedance adjustment terminal 26A can be changed in various ways.

In addition, in the embodiment, the first impedance adjustment terminal 26A is formed of a conductive material different from the internal terminal 20 and the external terminal 22 (for example, stainless steel). By being formed of different materials in this way, the material of the first impedance adjustment terminal 26A is not limited to the same material as the internal terminal 20 and the external terminal 22, and various materials can be used. When stainless steel is used, the manufacturing cost can be reduced and the strength can be increased.

In addition, in the embodiment, the internal terminal 20A at the end is a terminal for high-frequency signals. When the internal terminal 20A at the end is a terminal for high-frequency signals, the impedance deviation from the internal terminal 20C outside the end is likely to be a problem. However, since the first impedance adjustment terminal 26A is provided, the impedance deviation can be effectively suppressed.

Furthermore, in the embodiment, in addition to the internal terminal 20, an external terminal 22 is further provided, and the impedance adjustment terminal 26 is provided between the internal terminals 20A, 20B and the external terminal 22 located at the ends. According to this structure, while performing impedance adjustment of the impedance adjusting terminal 26, it is possible to perform an attracting function when, for example, the male connector 4 and the female connector 6 are fitted to the external terminal 22 with each other.

In addition, in the embodiment, as shown in FIG. 3B and the like, the first impedance adjustment terminal 26A is separately provided not only with the plurality of internal terminals 20 but also with the external terminals 22 as separate members. By making the first impedance adjustment terminal 26A independent from both the internal terminal 20 and the external terminal 22, the first impedance adjustment terminal 26A can be designed more freely.

In addition, in the embodiment, in addition to the first impedance adjustment terminal 26A, the second impedance adjustment terminal 26B is provided. Since the relationship between the second impedance adjustment terminal 26B and the internal terminal 20B of the end is the same as the relationship between the first impedance adjustment terminal 26A and the internal terminal 20A of the end described above, the description is omitted. The second impedance adjustment terminal 26B can also exhibit the same effect as that of the above-mentioned first impedance adjustment terminal 26A.

By providing the second impedance adjustment terminal 26B, not only the impedance of the internal terminal 20A of the terminal can be adjusted, but also the impedance of the internal terminal 20B of the terminal can be adjusted. As a result, the impedance of the entire plurality of internal terminals 20 can be adjusted more accurately.

As described above, the female connector 6 of the embodiment includes a plurality of internal terminals 20 arranged in a row, and an insulating member 24 that holds the plurality of internal terminals 20 in a state of being electrically insulated from each other. The female connector 6 further has an impedance adjustment terminal 26 arranged independently of the plurality of internal terminals 20 along the positions of the internal terminals 20A and 20B located at the ends among the plurality of internal terminals 20. In this way, by providing the impedance adjustment terminal 26, the impedance of the internal terminals 20A and 20B of the end can be adjusted. The internal terminals 20A and 20B located at the end, especially for high-frequency signal applications, are prone to impedance deviations from the internal terminals 20C other than the other ends. However, by providing the impedance adjustment terminal 26, the deviation can be easily suppressed.

In addition, the impedance adjustment terminal 26 can also function as a so-called "armored terminal" that prevents the resin in the connector from being shaved off due to the mating of the male connector 4 and the female connector 6. Furthermore, the impedance adjustment terminal 26 may be used to arbitrarily change the frequency band of the unnecessary resonance that is the cause of the deterioration of the VSWR characteristic.

In addition, in the above-mentioned embodiment, the case where both the internal terminal 20 and the external terminal 22 are provided was demonstrated, but it is not limited to this case. It may also be a case where the external terminal 22 is not provided, and only the internal terminal 20 is provided. In addition, in the embodiment, the case where the impedance adjustment terminal 26 is provided in the female connector 6 has been described, but it is not limited to this case, and the case where it is provided in the male connector 4 may also be used.

Not limited to the example shown in FIG. 4, the shape of the first impedance adjusting terminal 26A may take various shapes. For example, the first impedance adjustment terminal 50 shown in FIG. 5 may also be used. The distance between the first impedance adjusting terminal 50 and the inner terminal 20A of the end shown in FIG. 5 is a distance D3, and the area facing the side surface 28 of the inner terminal 20A in the D direction is an opposing area 52. By setting the distance D3 and the opposite region 52 instead of the above-mentioned distance D1 and the opposite region 29, the impedance of the internal terminal 20A of the end can be set to different values.

As mentioned above, although the present invention has been described with reference to the above-mentioned embodiment, the present invention is not limited to the above-mentioned embodiment. The present invention is fully described with reference to the accompanying drawings and related to the preferred embodiment. For those who are familiar with the technology, various changes or modifications are clear. It should be understood that such changes or modifications are included in the scope of this disclosure as long as they do not depart from the scope of the attached patent application. In addition, the combination of the elements of each embodiment or the change of the sequence can be realized without departing from the scope and idea of the present disclosure.

In addition, by appropriately combining any of the above-mentioned various embodiments, the effects of each can be exerted. [Industrial availability]
