<Housing 70>
The housing 70 is molded using the core 20 as an insert part. The housing 70 is formed with traces (gate traces 71) of gates G for discharging resin when the housing 70 is formed. The gate mark 71 is provided at a position separated from the opposing surfaces 35a and 55a along the direction in which the opposing surfaces 35a and 55a spread. A projecting piece 66 is provided at a position corresponding to the gate mark 71 . The protruding piece 66 is located inside the gate mark 71 formed on the housing 70 .

A housing 70 forms the exterior of the device connector 10 . Accordingly, one outlet 13 and the other outlet 14 of the air passage 12 are formed in the housing 70 . A first opening 72 and a second opening 73 are formed in the housing 70 . The first opening 72 is a portion that becomes one outlet 13 of the air passage 12 . The second opening 73 is a portion that becomes the other outlet 14 of the air passage 12 .

For example, the housing 70 may be shaped such that one end of the terminal fits into the recess 74 of the housing 70, or the other end of the terminal protrudes from the housing 70. good.

<Operation etc.>
An example of the operation of the molten resin when the housing 70 is molded using the core 20 as an insert part will be described. Molten resin is discharged from the gate G when the housing 70 is molded. At this time, the projecting piece 66 is positioned in front of the gate G. As shown in FIG. Therefore, the molten resin goes around the projecting piece 66 toward the air passage 12 . As a result, the injection pressure is weakened while the molten resin is moving toward the air passage 12, and the molten resin is less likely to enter the air passage 12. - 特許庁

A first entry route R1 and a second entry route R2 are conceivable as entry routes for the molten resin to bypass the projecting piece 66 and head toward the air passage 12 . The first intrusion route R1 is a route passing between the facing surfaces 35a and 55a. The second entry route R2 is a route passing between the end surface of the first portion 35 and the upper surface of the second portion 56. As shown in FIG. 4 to 7 schematically show the first entry route R1 and the second entry route R2.

The molten resin traveling along the first intrusion path R1 bypasses the projecting piece 66 and then intrudes between the facing surfaces 35a and 55a. At this time, the molten resin needs to go over the steps caused by the ribs 41 and the rib accommodation grooves 61 before reaching the air passage 12 . This makes it difficult for the molten resin to enter the air passage 12 .

The molten resin traveling along the second intrusion path R2 bypasses the projecting piece 66 and intrudes between the end surface of the first portion 35 and the upper surface of the second portion 56 . At this time, the molten resin needs to go over the steps caused by the protrusions 58 and the recesses 38 before reaching the air passage 12 . This also makes it difficult for the molten resin to enter the air passage 12 .

Further, the molten resin that advances along the second intrusion route R2 on the one outlet 13 side of the groove 37 enters between the facing surfaces 35a and 55a on the groove 37 side of the rib 41, and melts that advances along the first intrusion route R1. May merge with resin. Even in this case, since the cover 39 is provided in the portion of the groove 37 connected to the recess 38 , it is necessary to bypass the cover 39 before the merged molten resin reaches the air passage 12 . This also makes it difficult for the molten resin to enter the air passage 12 .

<Effects, etc.>
According to the device connector 10 configured as described above, the protruding piece 66 can hide the facing surfaces 35a and 55a from the gate G, thereby lengthening the entrance path of the resin from the gate G to the ventilation path 12, thereby increasing ventilation. It becomes difficult for the resin to enter the path 12 .

In addition, since the concave portion 38 and the convex portion 58 are provided, entry of the resin from the one outlet 13 side of the air passage 12 is suppressed.

In addition, since the air passage 12 is covered with the cover 39, entry of resin from the one outlet 13 side of the air passage 12 is suppressed.

In addition, by providing the two vertical ribs 42 and the first horizontal rib 43, the resin is prevented from entering from the side of the air passage 12 and from the other outlet 14 side.

[Modification]
FIG. 8 is a plan view showing a first core 130 according to a modification. FIG. 9 is a plan view showing a second core 150 according to a modification.

In the core in which the first core 130 and the second core 150 are united, the ribs 141 and the rib housing grooves 161 have different shapes from the ribs 41 and the rib housing grooves 61 . Specifically, the rib 141 further has a second lateral rib 44 . Further, the rib accommodation groove 161 further has a second lateral rib accommodation groove 64 . A second horizontal rib 44 connects the two vertical ribs 42 on one outlet 13 side. The second horizontal ribs 44 are provided on the first resin portion 34 like the two vertical ribs 42 and the first horizontal ribs 43 . A second transverse rib 44 passes over the cover 39 . The second lateral rib accommodating grooves 64 are formed in the second resin portion 54 like the two longitudinal rib accommodating grooves 62 and the first lateral rib accommodating grooves 63 . The second lateral rib receiving groove 64 is formed in a position and shape corresponding to the second lateral rib 44 . The second lateral ribs 44 are accommodated in the second lateral rib accommodating grooves 64 in a state in which the first core 30 and the second core 50 are combined.

By providing the second lateral ribs 44 and the second lateral rib accommodating grooves 64 , entry of resin from the one outlet 13 side of the ventilation path 12 is suppressed. For example, when the molten resin advancing along the second intrusion route R2 on the one outlet 13 side of the groove 37 enters between the opposing surfaces 35a and 55a on the groove 37 side of the rib 41, the second lateral rib 44 and the second lateral rib 44 and the second lateral rib 44 It is necessary to cross the step caused by the rib accommodation groove 64 . This makes it difficult for the molten resin traveling along the second entry path R2 to merge with the molten resin traveling along the first entry path R1.

In addition, although the projection piece 66 is described as being provided on the second core 50 in the embodiment, this is not an essential configuration. The projecting piece may be provided on the first core. In this case, the protruding piece is preferably provided so as to protrude from the first resin portion toward the second resin portion.

Also, the core may include a third core different from the first core and the second core. The third core may be combined with the first core on the side opposite to the second core. The third core may be combined with the second core on the side opposite to the first core. In this case, the projecting piece may be provided on the third core. When the protruding piece is provided on the third core, the first core and the second core may be formed with an accommodation recess for accommodating the protruding piece.

Also, although the embodiment has been described as having the concave portion 38 and the convex portion 58, this is not an essential configuration. The concave portion 38 and the convex portion 58 may be omitted.

Also, although the embodiment has been described as having the cover 39, this is not an essential configuration. Cover 39 may be omitted.

Also, although the ribs 41 and the rib housing grooves 61 are provided in the embodiment, this is not an essential configuration. The rib 41 and the rib accommodation groove 61 may be omitted. Moreover, even when the rib 41 and the rib accommodation groove 61 are provided, it is not necessary to provide the rib 41 in the first resin portion 34 and form the rib accommodation groove 61 in the second resin portion 54 . The rib may be provided in the second resin portion, and the rib accommodating groove may be formed in the first resin portion. That is, when ribs and rib accommodation grooves are provided, it is sufficient that one of the first resin portion and the second resin portion is provided with ribs and the other is formed with rib accommodation grooves.

In addition, each structure demonstrated by the said embodiment and each modification can be combined suitably, unless it mutually contradicts.
