Description

[Technical Field]

[0001] The present invention relates to a connector, and more particularly to a connector having a plurality of terminals arranged in a predetermined direction. [Background technology]

[0002] Patent Document 1 discloses a connector having a plurality of terminals arranged in two rows. As shown in Figure 18, a connector 90 in Patent Document 1 has a plurality of terminals 92, a housing (retaining member) 94 that holds the terminals 92, and two additional members (hold-downs) 96 provided on both ends of the housing 94.

[0003] As can be seen from FIG. 18 , the housing 94 has a peripheral wall 941 and a protruding wall 943. When viewed in the up-down direction (Z direction), the peripheral wall 941 has a rectangular frame shape that is long in the pitch direction (X direction). More specifically, the peripheral wall 941 has a pair of side walls 951 that extend in the pitch direction and a pair of connecting walls 953 that extend in the width direction (Y direction). The protruding wall 943 has a substantially rectangular parallelepiped shape that is long in the pitch direction. The protruding wall 943 is located inside the peripheral wall 941 in both the pitch direction and the width direction. The protruding wall 943 is connected to the peripheral wall 941 by a plurality of bottom wall portions (not shown).

[0004] 18 , each of the additional members 96 has a pair of side portions 961 and a connecting portion 963 that connects the side portions 961 to each other. Each of the side portions 961 partially covers the corresponding side wall 951 of the housing 94. In addition, the connecting portion 963 partially covers the corresponding connecting wall 953 of the housing 94. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2018-142456 Summary of the Invention [Problem to be solved by the invention]

[0006] In the connector 90 of Patent Document 1, the housing 94 is molded using resin. More specifically, the housing 94 is manufactured by pouring molten resin into a cavity of a mold (not shown). Generally, the molten resin is filled into the cavity from one end in the longitudinal direction of the cavity. In the case of the connector 90 of Patent Document 1, the one end in the longitudinal direction of the cavity is a portion corresponding to one of the connecting walls 953 of the housing 94. Therefore, the molten resin is filled into the cavity so as to flow from the portion corresponding to one of the connecting walls 953 of the housing 94 toward the portion corresponding to the other of the connecting wall 953.

[0007] As can be seen from FIG. 18 , the cross-sectional area of ​​the housing 94 cut along a plane perpendicular to the pitch direction varies significantly depending on the cut position. In particular, the cross-sectional area varies significantly when the cut position is on the connecting wall 953 compared to when the cut position is between the connecting wall 953 and the protruding wall 943. This means that a bottleneck may occur when molding the housing 94. Such a cavity structure is prone to insufficient filling, in which the molten resin does not properly fill the cavity. This tendency is particularly pronounced when the size of the housing 94 in the pitch direction is large. Therefore, the connector 90 of Patent Document 1 has the problem that it is difficult to increase the size of the housing 94 in the pitch direction. This also means that it is difficult to increase the number of terminals 92 of the connector 90. Therefore, there is a need for a connector equipped with a retaining member whose structure takes into account the fluidity of the molten resin so that the size of the housing 94 can be increased in the pitch direction.

[0020] 1 to 3, a connector 10 according to one embodiment of the present invention is a connector that can be mated with and separated from a mating connector 50 in the vertical direction. The connector 10 and the mating connector 50 are each board-mounted connectors that are mounted on the surface of a board (not shown). For example, the connector 10 is mounted on the top surface of a first board (not shown), and the mating connector 50 is mounted on the bottom surface of a second board (not shown). In this embodiment, the vertical direction is the Z direction. The +Z direction is upward, and the -Z direction is downward.

[0021] As shown in Figures 1 and 2, the mating connector 50 is a low-profile plug connector having a longitudinal axis in the pitch direction. The mating connector 50 includes a plurality of mating terminals 52, a mating holding member 54 that holds the mating terminals 52, and two mating hold-downs 56. The mating terminals 52 and the mating hold-downs 56 are each made of metal, and the mating holding member 54 is made of insulating resin. The mating hold-downs 56 are located at both ends of the mating holding member 54 in the pitch direction. In this embodiment, the pitch direction is a direction perpendicular to the up-down direction, which is the X direction.

[0022] As shown in FIGS. 1 and 2 , the mating terminals 52 are divided into two mating terminal rows 60. The two mating terminal rows 60 are aligned in a width direction perpendicular to both the pitch direction and the up-down direction. In this embodiment, the width direction is the Y direction. In each mating terminal row 60, the mating terminals 52 are aligned in the pitch direction at predetermined intervals. In this embodiment, the mating terminals 52 are held in the mating holding member 54 by insert molding. However, the present invention is not limited to this. For example, the mating terminals 52 may be held in the mating holding member 54 by a method other than insert molding, such as press-fitting.

[0023] 4 and 5, the mating terminal 52 includes a first mating terminal 521 and a second mating terminal 523. The first mating terminals 521 and the second mating terminals 523 are alternately arranged in the pitch direction. The two mating terminal rows 60 are rotationally symmetrical with respect to an axis extending in the up-down direction. As a result, the first mating terminals 521 and the second mating terminals 523 are aligned in the pitch direction.

[0024] As can be seen from Figures 4 and 5, in this embodiment, the first mating terminal 521 and the second mating terminal 523 have the same basic configuration but slightly different shapes. However, the present invention is not limited to this. The first mating terminal 521 and the second mating terminal 523 may have the same shape or different shapes. Note that detailed description of the shapes of the first mating terminal 521 and the second mating terminal 523 will be omitted.

[0025] As can be seen from FIGS. 1 and 2, the mating connector 50 has a top plate portion 501 and two accommodated portions 503. The top plate portion 501 is a part of the mating holding member 54. The accommodated portions 503 are composed of a part of the mating holding member 54 and a part of the mating terminals 52. The accommodated portions 503 correspond to the mating terminal rows 60, respectively, and extend in the pitch direction. The two accommodated portions 503 are connected to each other by the top plate portion 501 and protrude downward from the top plate portion 501. Each of the mating hold-downs 56 connects one of the ends of the accommodated portions 503 to each other. The mating hold-downs 56 have end accommodated portions 560 extending in the width direction.

[0026] As shown in Figures 1 and 2, connector 10 is a low-profile receptacle connector that is longitudinal in the pitch direction. Connector 10 includes a plurality of terminals 12, a retaining member 14 that holds terminals 12, and two hold-downs 16. Terminals 12 and hold-downs 16 are each made of metal, and retaining member 14 is made of insulating resin. Hold-downs 16 are located at both ends of retaining member 14 in the pitch direction.

[0027] As shown in Figures 1, 2, and 7, the terminals 12 are divided into two terminal rows 20. The two terminal rows 20 are aligned in the width direction. In each of the terminal rows 20, the terminals 12 are aligned in the pitch direction at predetermined intervals. In this embodiment, the terminals 12 are held in the holding member 14 by press-fitting. However, the present invention is not limited to this. For example, the terminals 12 may be held in the holding member 14 by a method other than press-fitting, such as insert molding.

[0028] 9 to 12, the holding member 14 has two side portions 141, two storage portions 143, island-shaped portions 145, and a plurality of connecting portions 147. The side portions 141, the storage portions 143, and the island-shaped portions 145 each extend in the pitch direction. The island-shaped portions 145 are located between the side portions 141 in the width direction. In this embodiment, the island-shaped portions 145 have a generally frame-like shape when viewed in the up-down direction. The storage portions 143 correspond to the side portions 141, respectively. More specifically, each storage portion 143 is located between the corresponding side portion 141 and island-shaped portion 145 in the width direction. In this embodiment, each storage portion 143 has a groove-like shape extending in the pitch direction. In the pitch direction, the size of the storage portion 143 is equal to the size of the side portion 141. In other words, the storage portion 143 penetrates the holding member 14 in the pitch direction. Furthermore, the size of the side portion 141 in the pitch direction is smaller than the size of the island-shaped portion 145. Therefore, the accommodation portion 143 is located within a range that does not exceed the island-shaped portion 145 in the pitch direction.

[0029] 1, 2 and 7, the terminal rows 20 correspond to the side portions 141 of the holding member 14 and to the accommodating portions 143. Furthermore, the terminal rows 20 correspond to the mating terminal rows 60, and the terminals 12 correspond to the mating terminals 52.

[0030] 4 and 5, the terminal 12 has a first terminal 121 and a second terminal 123. The first terminals 121 and the second terminals 123 are arranged alternately in the pitch direction. The first terminals 121 correspond to the first mating terminals 521, and the second terminals 123 correspond to the second mating terminals 523. The two terminal rows 20 are rotationally symmetrical with respect to an axis along the vertical direction. As a result, the first mating terminals 521 and the second mating terminals 523 are aligned in the pitch direction.

[0031] As can be seen from Figures 4 and 5, in this embodiment, first terminal 121 and second terminal 123 have the same basic configuration but slightly different shapes. However, the present invention is not limited to this. First terminal 121 and second terminal 123 may have the same shape or different shapes. Note that detailed description of the shapes of first terminal 121 and second terminal 123 will be omitted.

[0032] As shown in FIGS. 4 and 5 , each of the terminals 12 has a contact 131. In this embodiment, each of the terminals 12 further has an additional contact 133. The contact 131 and the additional contact 133 are supported by a support portion 135 and are spaced apart and opposed to each other in the width direction. Each of the first terminals 121 is partially embedded in the corresponding side portion 141 and held by the holding member 14. Each of the second terminals 123 is partially embedded in the island-shaped portion 145 and held by the holding member 14. The support portion 135 of each of the terminals 12 is not embedded in the holding member 14 and is elastically deformable. In this way, each of the terminals 12 is a spring contact. The elastic deformation of the support portion 135 allows the distance between the contact 131 and the additional contact 1330 to change in the width direction.

[0033] 4 and 5, each of the accommodating portions 143 of the holding member 14 is an area that accommodates a portion of the mating connector 50 when the connector 10 and the mating connector 50 are mated. More specifically, the accommodating portions 143 are areas that accommodate the accommodated portions 503 of the mating connector 50. As shown in FIGS. 7 and 8, the contacts 131 and the additional contacts 133 of the terminals 12 are at least partially located within the corresponding accommodating portions 143. When the connector 10 and the mating connector 50 are mated, the contacts 131 and the additional contacts 133 come into contact with the corresponding mating terminals 52.

[0034] As shown in Figures 13 to 16, each hold-down 16 has an end wall portion 161 and two side connecting portions 163. The end wall portion 161 has a generally inverted U-shape when viewed in the width direction and extends in the width direction. The side connecting portions 163 are provided at both ends of the end wall portion 161 in the width direction. Each side connecting portion 163 has a generally inverted J-shape when viewed in the pitch direction and extends in the pitch direction. In this embodiment, each hold-down 16 further has a side embedded portion 167 extending in the pitch direction from the side connecting portion 163. In this embodiment, the side embedded portion 167 has a generally V-shape when viewed in the width direction. However, the present invention is not limited to this. The shape of the side embedded portion 167 is not particularly limited.

[0035] As shown in Figures 13 to 16, the hold-down 16 of this embodiment further has a central connector 169. The central connector 169 extends inward in the pitch direction from the lower end of the end wall portion 161 on the inner side in the pitch direction, then extends upward and further inward in the pitch direction. The central connector 169 is spaced apart from the side connectors 163 in the width direction. In this embodiment, the central connector 169 is bifurcated at its tip end. However, the present invention is not limited to this. The hold-down 16 does not have to have the central connector 169. Furthermore, the central connector 169 does not have to be bifurcated.

[0036] 13 to 16, the hold-down 16 further has two central embedded portions 171 extending from the central connecting portion 169. However, the present invention is not limited to this. The hold-down 16 does not have to have a central embedded portion 171. Furthermore, depending on the shape of the central connecting portion 169, the number of central embedded portions 171 may be one.

[0037] As shown in FIG. 7, end wall portion 161 of hold-down 16 is located at the end of connector 10 in the pitch direction. Side connecting portion 163 connects end wall portion 161 to each of side portions 141 of retaining member 14. As can be seen from FIGS. 6, 7, and 13, side embedded portions 167 are embedded in each of side portions 141 of retaining member 14. In this embodiment, hold-down 16 is attached to retaining member 14 by insert molding. However, the present invention is not limited to this. Hold-down 16 may also be attached to retaining member 14 by a method other than insert molding, such as press-fitting.

[0038] As can be seen from Figure 7, the end wall 161 of the hold-down 16 is spaced apart from the retaining member 14 in the pitch direction. In other words, the retaining member 14 does not overlap the end wall 161 in the up-down direction. As can be seen from Figures 7 and 8, a space is provided between the accommodation portion 143 and the end wall 161 in the pitch direction. Furthermore, an end accommodation portion 165 is formed between the retaining member 14 and the end wall 161 in the pitch direction.

[0039] 1, central connecting portion 169 of hold-down 16 is partially embedded in island-shaped portion 145 of retaining member 14. Central connecting portion 169 connects end wall portion 161 to island-shaped portion 145 of retaining member 14. In addition, as can be seen from FIGS. 1 and 6, central embedded portion 171 of hold-down 16 extends from central connecting portion 169 toward island-shaped portion 145 of retaining member 14 and is embedded in island-shaped portion 145.

[0040] As shown in FIG. 1 , a side surface 173 on the outer side in the pitch direction of the central connecting portion 169 and an upper surface 175 are exposed to the outside of the holding member 14. The boundary between the side surface 173 and the upper surface 175 of the central connecting portion 169 functions as a protective portion 177 that partially protects the island-shaped portion 145 of the holding member 14. More specifically, the protective portion 177 at least partially covers and protects the upper corners of the end portions of the island-shaped portion 145 of the holding member 14 in the pitch direction. The protective portion 177 prevents the mating connector 50 from contacting the island-shaped portion 145 and scraping or breaking the island-shaped portion 145 when the connector 10 is mated with the mating connector 50. Thus, in this embodiment, the hold-down 16 has a protective portion 177 that at least partially covers and protects the upper corners of the end portions of the island-shaped portion 145 of the holding member 14 in the pitch direction.

[0041] As can be seen from FIG. 7 , in this embodiment, both ends of the accommodating portion 143 of the holding member 14 are located inside both ends of the island-shaped portion 145 in the pitch direction. In addition, the central connecting portion 169 of the hold-down 16 is separated from the side connecting portion 163 in the width direction. Therefore, the connector 10 of this embodiment has through-hole regions 149 that are located outside the holding member 14 in a plane perpendicular to the up-down direction and penetrate the holding member 14 in the up-down direction. In this embodiment, the number of through-hole regions 149 is four. Each through-hole region 149 is located between either the central connecting portion 169 or one of the side connecting portions 163 in the width direction. However, the present invention is not limited to this. The connector 10 may have at least one through-hole region 149. For example, if the hold-down 16 does not have a central connecting portion 169, the number of through-hole regions 149 is two. In any case, in this embodiment, when looking outward in the pitch direction from inside the storage section 143, a portion of the hold-down 16 or the end wall section 161 can be seen without being obstructed by the holding member 14.

[0042] As can be seen from Figures 9 and 10, the cross-sectional area of ​​the retaining member 14 of the connector 10 according to this embodiment, when cut along a plane perpendicular to the pitch direction, is smallest at the end in the pitch direction. In other words, this structure does not have any bottlenecks when molding the retaining member 14. In this way, the retaining member 14 improves the fluidity of the molten resin during molding. As a result, the size of the retaining member 14 in the pitch direction can be easily increased, and the number of terminals 12 can be easily increased. In this way, the connector 10 according to this embodiment allows the number of terminals 12 to be easily increased.

[0043] As can be seen from FIGS. 9 and 10 , the end of the holding member 14 in the pitch direction is the end of the island-shaped portion 145 in the pitch direction. Therefore, the holding member 14 is molded in a mold cavity such that molten resin flows from a portion corresponding to one end of the island-shaped portion 145 in the pitch direction toward a portion corresponding to the other end. Therefore, as shown in FIG. 17 , the holding member 14 of the connector 10 according to this embodiment typically has a gate mark 151 near one end of the island-shaped portion 145 in the pitch direction, specifically, at its bottom. The gate mark 151 is the mark of the entrance gate of the cavity of the mold (not shown) used to mold the holding member 14. The bottom of the island-shaped portion 145 faces downward in the vertical direction. Incidentally, incomplete filling of the molten resin into the cavity can be easily resolved by increasing the number of gates. However, increasing the number of gates increases the likelihood of weld lines occurring in the molded product, i.e., the holding member 14. Since a weld line reduces the strength of a molded product, it is preferable to have a single gate, and in that sense the configuration of the holding member 14 of this embodiment is effective.

[0044] The present invention has been described above by presenting an embodiment thereof, but the present invention is not limited to the above-described embodiment, and various modifications and changes are possible within the scope of the gist of the present invention.

[0045] For example, in the above embodiment, the pitch-direction size of the side portion 141 of the holding member 14 is smaller than the pitch-direction size of the island-shaped portion 145, but the pitch-direction size of the side portion 141 of the holding member 14 may be larger than the pitch-direction size of the island-shaped portion 145.

[0046] Furthermore, in the above embodiment, the terminals 12 in the terminal row 20 are arranged so that the contacts 131 of the first terminals 121 and the contacts 131 of the second terminals 123 are staggered, but the terminals 12 in the terminal row 20 may be arranged so that the contacts 131 are linearly arranged. In this case, the first terminals 121 and the second terminals 123 may have the same shape.

[0047] Furthermore, in the above embodiment, the island-shaped portion 145 has a substantially frame shape, but may have a substantially rectangular parallelepiped shape like the projecting wall 943 in Patent Document 1. [Explanation of symbols]
