Description

The present invention relates to a connector, and particularly to a connector including a plurality of terminals arranged in a predetermined direction.

Patent Document 1 discloses a connector including a plurality of terminals arranged in two rows. As shown in FIG. 18, the connector 90 of Patent Document 1 includes a plurality of terminals 92, a housing (holding member) 94 that holds the terminals 92, and two additional members (hold down members) provided at both ends of the housing 94. )96.

As understood from FIG. 18, the housing 94 has a peripheral wall 941 and a projecting wall 943. When viewed along the vertical direction (Z direction), the peripheral wall 941 has a rectangular frame shape that is long in the pitch direction (X direction). Specifically, the peripheral wall 941 has a pair of side walls 951 extending in the pitch direction and a pair of connecting walls 953 extending in the width direction (Y direction).

Japanese Patent Application Publication No. 2018-142456

In the connector 90 of Patent Document 1, the housing 94 is molded using resin. Specifically, the housing 94 is manufactured by pouring molten resin into a cavity of a mold (not shown). Generally, the cavity is filled with molten resin from one end in the longitudinal direction of the cavity. In the case of the connector 90 of Patent Document 1, one end of the cavity in the longitudinal direction corresponds 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 a portion of the housing 94 corresponding to one of the connecting walls 953 to a portion corresponding to the other connecting wall 953.

As understood 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 cutting position. In particular, the cross-sectional area is significantly different when the cutting position is on the connecting wall 953 and when it is between the connecting wall 953 and the projecting wall 943. This means that it may become a bottleneck when molding the housing 94. Such a cavity structure tends to cause filling failures in which the molten resin is not properly filled into the cavity. This tendency is particularly noticeable when the size of the housing 94 in the pitch direction is large. Therefore, the connector 90 of Patent Document 1 has a problem in 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 that includes a holding member that has a structure that takes into consideration the fluidity of the molten resin so that the size of the housing 94 in the pitch direction can be increased.

The counterpart hold-downs 56 are located at both ends of the counterpart holding member 54 in the pitch direction. In this embodiment, the pitch direction is a direction perpendicular to the up-down direction, and is the X direction.

As shown in FIGS. 1 and 2, the mating terminal 52 is divided into two mating terminal rows 60. The two mating terminal rows 60 are arranged 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 of the mating terminal rows 60, the mating terminals 52 are arranged in the pitch direction at predetermined intervals. In this embodiment, the mating terminal 52 is held by the mating holding member 54 by insert molding. However, the present invention is not limited to this. For example, the mating terminal 52 may be held by the mating holding member 54 by a method other than insert molding, such as press fitting.

As understood from FIGS. 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 arranged alternately in the pitch direction. The two mating terminal rows 60 are rotationally symmetrical with respect to an axis along the vertical direction. As a result, the first mating terminal 521 and the second mating terminal 523 are lined up in the pitch direction.

As can be understood from FIGS. 4 and 5, in this embodiment, the first mating terminal 521 and the second mating terminal 523 have the same basic configuration, but have 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 may have different shapes. Note that a detailed description of the shapes of the first mating terminal 521 and the second mating terminal 523 will be omitted.

As understood 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 counterpart holding member 54. The accommodated portion 503 includes a part of the mating holding member 54 and a part of the mating terminal 52. The accommodated portions 503 correspond to the mating terminal rows 60, respectively, and extend in the pitch direction.

The two terminal rows 20 are rotationally symmetrical with respect to an axis along the vertical direction. As a result, the first mating terminal 521 and the second mating terminal 523 are lined up in the pitch direction.

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

As shown in FIGS. 4 and 5, each terminal 12 has a contact 131. As shown in FIGS. In this embodiment, each of the terminals 12 further includes an additional contact 133.

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 portion 145 and held by the holding member 14 . Each support portion 135 of the terminal 12 is not embedded in the holding member 14 and is elastically deformable. Thus, each of the terminals 12 is a spring contact. By elastically deforming the support portion 135, the distance between the contact point 131 and the additional contact point 1330 can be changed in the width direction.

As understood from FIGS. 4 and 5, each of the accommodating portions 143 of the holding member 14 is a region that accommodates a portion of the mating connector 50 when the connector 10 and the mating connector 50 are fitted together. be. Specifically, the accommodating portions 143 are areas that accommodate the accommodating portions 503 of the mating connector 50, respectively. As shown in FIGS. 7 and 8, the contact 131 and the additional contact 133 of the terminal 12 are at least partially located within the corresponding housing 143. As shown in FIGS. When the connector 10 and the mating connector 50 are fitted, the contacts 131 and the additional contacts 133 come into contact with the corresponding mating terminals 52.

As shown in FIGS. 13 to 16, each holddown 16 has an end wall portion 161 and two side connecting portions 163. As shown in FIGS. The end wall portion 161 has a substantially inverted U shape when viewed along 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 of the side connecting portions 163 has a substantially inverted J shape when viewed in the pitch direction, and extends in the pitch direction. In this embodiment, each of the holddowns 16 further includes a side buried portion 167 extending from the side connecting portion 163 in the pitch direction. In this embodiment, the side buried portion 167 has a substantially V-shape when viewed along the width direction. However, the present invention is not limited to this. The shape of the side buried portion 167 is not particularly limited.

As shown in FIGS. 13 to 16, the hold down 16 of this embodiment further includes a central connecting portion 169. As shown in FIGS. The central connecting portion 169 extends from the lower end of the end wall portion 161 on the inner side in the pitch direction, extends inward in the pitch direction, then extends upward, and further extends inward in the pitch direction. The central connecting portion 169 is spaced apart from the side connecting portions 163 in the width direction. In this embodiment, the central connecting portion 169 is bifurcated at its distal end side. However, the present invention is not limited to this. Holddown 16 may not have central connection 169. Further, the central connecting portion 169 does not have to be bifurcated.

As shown in FIGS. 13 to 16, the holddown 16 further includes two central buried portions 171 extending from the central connecting portion 169. As shown in FIGS. However, the present invention is not limited to this. Hold down 16 may not have central buried portion 171. Further, depending on the shape of the central connecting portion 169, the number of central buried portions 171 may be one.

As shown in FIG. 7, the end wall portion 161 of the holddown 16 is located at the end of the connector 10 in the pitch direction. The side connecting portion 163 connects the end wall portion 161 and each of the side portions 141 of the holding member 14. As understood from FIGS. 6, 7, and 13, the side buried portions 167 are embedded in the side portions 141 of the holding member 14, respectively. In this embodiment, the hold down 16 is attached to the holding member 14 by insert molding. However, the present invention is not limited to this. The hold down 16 may be attached to the holding member 14 by a method other than insert molding, for example by press fitting.

As understood from FIG. 7, the end wall portion 161 of the holddown 16 is spaced apart from the holding member 14 in the pitch direction. In other words, the holding member 14 does not overlap the end wall portion 161 in the vertical direction. As understood from FIGS. 7 and 8, a space is provided between the housing portion 143 and the end wall portion 161 in the pitch direction. Furthermore, an end accommodating portion 165 is formed between the holding member 14 and the end wall portion 161 in the pitch direction.

As can be seen from FIG. 1, the central link 169 of the holddown 16 is partially embedded in the island 145 of the retaining member 14. The central connecting portion 169 connects the end wall portion 161 and the island portion 145 of the holding member 14 . In addition, as can be seen from FIGS. 1 and 6, the central buried portion 171 of the hold down 16 extends from the central connecting portion 169 toward the island portion 145 of the holding member 14, and is embedded in the island portion 145. ing.

As shown in FIG. 1, a side surface 173 on the outside in the pitch direction and a top surface 175 of the central connecting portion 169 are exposed to the outside of the holding member 14. The boundary between the side surface 173 and the top surface 175 of the central connecting portion 169 functions as a protection portion 177 that partially protects the island portion 145 of the holding member 14 . Specifically, the protection portion 177 at least partially covers and protects the upper corner of the pitch direction end of the island portion 145 of the holding member 14 . The protective portion 177 prevents the mating connector 50 from contacting the island portion 145 and scraping or breaking the island portion 145 when the connector 10 is mated with the mating connector 50 . As described above, in the present embodiment, the hold-down 16 includes the protection part 177 that at least partially covers and protects the upper corner of the end of the island-like part 145 of the holding member 14 in the pitch direction.

As understood 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 holddown 16 is spaced apart from the side connecting portions 163 in the width direction. Therefore, the connector 10 of this embodiment has a penetration region 149 located outside the holding member 14 and penetrating in the vertical direction in a plane perpendicular to the vertical direction. In this embodiment, the number of penetration regions 149 is four. Each of the penetrating regions 149 is located between one of the central connecting portion 169 and the side connecting portions 163 in the width direction. However, the present invention is not limited to this. Connector 10 only needs to have at least one penetration area 149. For example, if the holddown 16 does not have a central connection 169, the number of penetration areas 149 is two. In any case, in this embodiment, when looking outward in the pitch direction from inside the housing portion 143, a portion of the hold down 16 or the end wall portion 161 can be visually recognized without being obstructed by the holding member 14.

As understood from FIGS. 9 and 10, in the holding member 14 of the connector 10 according to the present embodiment, the cross-sectional area cut along a plane perpendicular to the pitch direction is smallest at the ends in the pitch direction. In other words, this structure does not have a bottleneck portion when molding the holding member 14. In this way, the holding member 14 has improved fluidity of the molten resin during molding. As a result, the size of the holding member 14 in the pitch direction can be easily increased, and the number of terminals 12 can be easily increased. In this way, in the connector 10 of this embodiment, the number of terminals 12 can be easily increased.

As understood from FIGS. 9 and 10, the end of the holding member 14 in the pitch direction is the end of the island portion 145 in the pitch direction. Therefore, the holding member 14 is molded in such a way that the molten resin flows from a portion corresponding to one end of the island portion 145 in the pitch direction to a portion corresponding to the other end in the mold cavity. be exposed. Therefore, as shown in FIG. 17, the holding member 14 of the connector 10 according to this embodiment is usually provided with a gate mark 151 near one end in the pitch direction of the island portion 145, specifically at the bottom thereof. Note that the gate mark 151 is a mark of an entrance gate of a cavity of a mold (not shown) used for molding the holding member 14. Further, the bottom portion of the island-shaped portion 145 is a portion facing downward in the vertical direction. Incidentally, failure to fill the cavity with molten resin can be easily resolved by increasing the number of gates. However, when the number of gates is increased, weld lines are likely to occur in the molded product, that is, the holding member 14. Since the weld line reduces the strength of the molded product, it is preferable that there be only one gate, and in this sense, the configuration of the holding member 14 of this embodiment is effective.

Although the present invention has been described above with reference to embodiments, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made without departing from the gist of the present invention. It is.

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

Further, in the above embodiment, each terminal 12 of the terminal row 20 is arranged such that the contact points 131 of the first terminal 121 and the contacts 131 of the second terminal 123 are arranged in a staggered arrangement. The terminals 12 of each of the terminals 12 may be arranged such that the contacts 131 are arranged in a linear array. In that case, the first terminal 121 and the second terminal 123 may have the same shape.

Furthermore, although the island portion 145 has a substantially frame shape in the above embodiment, it may have a substantially rectangular parallelepiped shape like the projecting wall 943 of Patent Document 1.
