The present disclosure relates to a connector.
Conventionally, a connector to be connected to an electric device for vehicle is known (see, for example, Patent Document 1). A connector described in Patent Document 1 is provided with a plurality of terminal-equipped wires, a housing made of resin and having the plurality of terminal-equipped wires embedded therein, and a sealing cover for covering the housing.
The housing includes a tubular receptacle provided with an opening for exposing terminals.
The sealing cover is provided with a cover body for covering the opening of the receptacle, a breathable film, and a shield shell made of metal and to be assembled with the cover body. The cover body includes a fitting portion to be fit into the receptacle. The fitting portion is provided with a vent penetrating therethrough in an axial direction of the receptacle. The breathable film covers the vent. The breathable film has waterproofness and breathability. The passage of gases through the vent is allowed and the passage of liquids is inhibited by the breathable film.
An annular surrounding wall portion projecting in the axial direction is provided around the vent. The touch of worker's fingers with the breathable film, for example, during an assembling operation of the shield shell and the cover body, is suppressed by the surrounding wall portion.
A liquid such as water may intrude between the cover body and the shield shell. If such a liquid intrudes into an inner peripheral side of the surrounding wall portion, this liquid may stay on the surface of the breathable film.
The present disclosure aims to provide a connector capable of suppressing the stay of a liquid on a breathable film.
The present disclosure is directed to a connector with a plurality of terminals parallel to each other, a plurality of wires to be respectively connected to the plurality of terminals, a housing made of resin and including a tubular portion having an opening for exposing end parts of the plurality of terminals and a holding portion projecting from the tubular portion toward an outer peripheral side of the tubular portion, the holding portion holding the plurality of terminals and the plurality of wires, and a cover for covering the opening by being inserted into the tubular portion, the end part of each terminal being provided with a bolt hole, the bolt hole penetrating in an axial direction of the tubular portion, a bolt being inserted into the bolt hole, the cover including a cover body made of resin, the cover body having a vent penetrating in the axial direction, the cover body covering the opening, and a breathable film for covering the vent from a side opposite to the plurality of terminals in the axial direction, the breathable film allowing passage of gases and inhibiting passage of liquids, the cover body including an inner wall surrounding an outer periphery of the breathable film and an outer wall located on an outer peripheral side of the inner wall and including an outer peripheral edge of the cover body, the inner wall including an inner discharge port allowing communication between inside and outside of the inner wall in a direction orthogonal to the axial direction, the outer wall including an outer discharge port allowing communication between inside and outside of the outer wall in a direction orthogonal to the axial direction, and the inner discharge port facing an inner peripheral surface of the outer wall, the outer discharge port facing an outer peripheral surface of the inner wall.
According to the present disclosure, the stay of a liquid on a breathable film can be suppressed.
First, embodiments of the present disclosure are listed and described.
According to this configuration, if a liquid intrudes into an inner peripheral side of the inner wall, this liquid is easily discharged to the outer peripheral side of the inner wall through the inner discharge port. Further, if a liquid intrudes into an inner peripheral side of the outer wall, this liquid is easily discharged to an outer peripheral side of the outer wall through the outer discharge port. Here, the inner discharge port is facing the inner peripheral surface of the outer wall, and the outer discharge port is facing the outer peripheral surface of the inner wall. Thus, for example, if a liquid intrudes into the inner peripheral side of the outer wall through the discharge port, this liquid is less likely to directly reach the inner discharge port. In this way, the liquid is less likely to intrude into the inner peripheral side of the inner wall. From the above, the stay of the liquid on the breathable film can be suppressed.
According to this configuration, if the connector is arranged in such a posture that the outer discharge port is open downward in a vertical direction, the inner discharge port is open obliquely downward. In this way, the liquid having intruded into the inner peripheral side of the inner wall is easily discharged to the outer peripheral side of the inner wall through the inner discharge port by the weight thereof. At this time, since the outer discharge port is open downward, the liquid discharged from the inner discharge port is easily discharged to the outer peripheral side of the outer wall through the outer discharge port by the weight thereof. Therefore, an effect of suppressing the stay of the liquid on the breathable film can be made more noticeable by arranging the connector in the above posture.
According to this configuration, if the connector is arranged in such a posture that the outer discharge port is open downward in the vertical direction, the extending portion extends obliquely downward. In this way, the liquid having intruded into the inner peripheral side of the inner wall flows obliquely downward along the extending portion after reaching the extending portion by the weight thereof. In this way, the liquid having intruded into the inner peripheral side of the inner wall is easily discharged to the outer peripheral side of the inner wall through the inner discharge port. Therefore, the effect of suppressing the stay of the liquid on the breathable film can be made even more noticeable by arranging the connector in the above posture.
According to this configuration, the outer discharge port is covered by the shield shell from the outer peripheral side of the outer wall. In this way, the liquid is less likely to intrude from the outer peripheral side into the inner peripheral surface of the outer wall through the outer discharge port. Therefore, it can be suppressed that the liquid reaches the breathable film.
According to this configuration, since the separation wall is located between the two mutually adjacent ones of the terminals, these two terminals can be suitably insulated from each other. Further, an insulation distance between the two terminals can be reduced as compared to the case of using a cover body including no separation wall. Therefore, an increase in the size of the connector in a parallel direction of the plurality of terminals can be suppressed.
According to this configuration, if the cover is inserted into the tubular portion while being inverted about the center axis of the tubular portion with respect to the proper posture, the insertion of the cover into the tubular portion is restricted by the contact of the coupling wall with the terminal. In this way, a worker easily notices the erroneous assembling of the cover with the tubular portion.
According to this configuration, the separation wall and the facing wall are coupled by both the first coupling wall and the second coupling wall. The second coupling wall is located between the first coupling wall and the second extending portion of the terminal. From these, the separation wall and the facing wall can be improved in strength while the interference of the second coupling wall and the terminal is avoided.
According to this configuration, since the holding portion and the tubular portion are coupled by the rib, the tilt of the holding portion with respect to the tubular portion can be suppressed.
According to this configuration, a part of a mold is arranged in a space where the recess is formed and a resin material for constituting the housing is filled around this part during the injection molding of the housing. Thus, the rib is cooled by causing a refrigerant to flow inside the part of the mold. Since the rib can be solidified earlier than other parts in this way, the tilt of the holding portion with respect to the tubular portion can be suppressed. Therefore, a reduction in the dimensional accuracy of the housing can be suppressed.
Further, according to the above configuration, since the rib includes the recess, the amount of the resin material used for the housing can be reduced and the housing can be reduced in weight.
Preferably, an interlock connector for electrically detecting whether or not the housing is connected to a connection target at a proper position is provided inside the tubular portion, and the interlock connector is provided in parallel to the plurality of terminals in a parallel direction of the plurality of terminals.
According to this configuration, the plurality of terminals and the interlock connector are provided in parallel in the parallel direction of the plurality of terminals. Thus, as compared to the case where the terminals and the interlock connector are arranged in parallel in a direction intersecting both the parallel direction and the axial direction, an increase in the size of the housing in the intersecting direction can be suppressed.
Preferably, the cover body includes an accommodating portion for accommodating one end of the interlock connector, and the accommodating portion is configured to restrict insertion of the cover into the tubular portion by contacting the terminal if the cover is inserted into the tubular portion while being inverted about a center axis of the tubular portion with respect to a proper posture.
According to this configuration, if the cover is inserted into the tubular portion while being inverted about the center axis of the tubular portion with respect to the proper posture, the insertion of the cover into the tubular portion is restricted by the contact of the accommodating portion with the terminal. In this way, the worker easily notices the erroneous assembling of the cover with the tubular portion.
Preferably, the tubular portion includes a partition wall partitioning inside of the tubular portion between the plurality of terminals and the interlock connector. According to this configuration, since the partition wall is provided inside the tubular portion, an insulation distance between the plurality of terminals and the interlock connector can be reduced as compared to the case where the partition wall is not provided. Therefore, an increase in the size of the connector in the parallel direction of the plurality of terminals can be suppressed.
A specific example of a connector of the present disclosure is described below with reference to the drawings. For the convenience of description, some components may be shown in an exaggerated or simplified manner in each drawing. Further, a dimension ratio of each part may be different in each figure. Note that the present disclosure is not limited to these illustrations, but is represented by claims and intended to include all changes in the scope of claims and in the meaning and scope of equivalents. “Orthogonal” in this specification means not only strictly orthogonal, but also substantially orthogonal within a range in which functions and effects in this embodiment are achieved.

The core wire 21 is, for example, a stranded wire formed by twisting a plurality of metal strands. A cross-sectional shape of the core wire 21 orthogonal to a length direction is, for example, a circular shape.
The core wire 21 is exposed from the insulation coating 22 at an end part of the wire 20. The core wire 21 exposed from the insulation coating 22 is electrically connected to the wire connecting portion 14 of the terminal 10, for example, by crimping.

The first partition wall 33 extends in the Z-axis direction. The first partition wall 33 couples parts facing each other in the Y-axis direction, out of the inner wall of the tubular portion 31. Therefore, the inside of the tubular portion 31 is partitioned into a part where the two terminals 10 are located and a part where the interlock connector IC is located by the first partition wall 33.
The second partition wall 34 is for partitioning the part where the interlock connector IC is located, out of the inside of the tubular portion 31, in the Z-axis direction. The second partition wall 34 couples the inner wall of the tubular portion 31 and the first partition wall 33.

The first engaging groove 39 extends more toward one side in the circumferential direction than the second engaging groove 40. The second engaging groove 40 extends more toward the other side in the circumferential direction than the first engaging groove 39.
“One side in the circumferential direction” in this embodiment means a counterclockwise direction when the second end part 31b is viewed from the first end part 31a of the tubular portion 31 in the Z-axis direction, and the “other side in the circumferential direction” means a clockwise direction.

A cross-sectional shape of the recess 46 orthogonal to the Z-axis direction is, for example, a rectangular shape long in the Y-axis direction. This cross-sectional shape is the same over the entire recess 46 in the Z-axis direction. That is, the inner wall of the rib 45 forming the recess 46 extends in the Z-axis direction over the entire periphery of the recess 46. As shown by a two-dot chain line in
A projecting amount of the rib 45 from the outer surface of the holding portion 43 decreases with distance from the tubular portion 31 in the Y-axis direction.

The outer wall 89 includes an outer discharge port 90 allowing communication between the inside and outside of the outer wall 89 in a direction orthogonal to the Z-axis direction. The inner and outer discharge ports 88, 90 are oriented in mutually different directions. The entire inner discharge port 88 is facing the inner peripheral surface of the outer wall 89. The entire outer discharge port 90 is facing the outer peripheral surface of the inner wall 86.
A virtual axis extending in a communicating direction of the inner discharge port 88 is referred to as a first virtual axis L1, and a virtual axis extending in a communicating direction of the outer discharge port 90 is referred to as a second virtual axis L2. Further, an intersection of the first and second vertical axes L1, L2 is referred to as an intersection P.
As shown in
The entire inner discharge port 88 is closer to a side where the outer discharge port 90 is located than the intersection P in an axial direction of the second virtual axis L2, i.e. the X-axis direction. In other words, the entire inner discharge port 88 is located closer to the side where the outer discharge port 90 is located than a third virtual axis L3 extending in the Y-axis direction and passing through the intersection P.
If the outer discharge port 90 is oriented in a direction of 6 o'clock, the inner discharge port 88 is preferably oriented, for example, to a region between 3 o'clock and 9 o'clock. However, a case where the entire inner discharge port 88 is not facing the inner peripheral surface of the outer wall 89 is excluded.
The inner wall 86 has a first end edge 86a and a second end edge 86b forming the inner discharge port 88. The first end edge 86a is located closer to the outer discharge port 90 than the second end edge 86b.
The inner wall 86 is provided with a first extending portion 87a extending to include the first end edge 86a and a second extending portion 87b extending to include the second end edge 86b. The first and second extending portions 87a, 87b are facing each other. The first extending portion 87a corresponds to an “extending portion”.
A part of the inner wall 86 except the first and second extending portions 87a, 87b forms, for example, an arcuate shape along the outer peripheral edge of the breathable film 100.

Here, the first coupling wall 93 is configured to restrict the insertion of the cover 70 into the tubular portion 31 by contacting the first extending portion 11 of the terminal 10 if the cover 70 is inserted into the tubular portion 31 while being inverted about a center axis of the tubular portion 31 with respect to a proper posture. In this embodiment, the projecting amount of the first coupling wall 93 from the lid portion 81 is larger than a distance from the lid portion 81 to the first extending portion 11 in the Z-axis direction.

As shown in
A projecting amount of the accommodating portion 95 from the lid portion 81 is less than that of each of the separation wall 91, the facing wall 92, the first coupling wall 93 and the second coupling wall 94 from the lid portion 81 and larger than the distance from the lid portion 81 to the first extending portion 11 of the terminal 10 in the Z-axis direction.
Here, if the cover 70 does not include the first coupling wall 93 and is inserted into the tubular portion 31 while being inverted about the center axis of the tubular portion 31 with respect to the proper posture, the accommodating portion 95 is provided at a position capable of contacting the first extending portion 11 of the terminal 10. That is, the accommodating portion 95 is configured to restrict the insertion of the cover 70 into the tubular portion 31 by contacting the terminal 10 if the cover 70 does not include the first coupling wall 93.
An unillustrated shorting pin is provided inside the accommodating portion 95. By accommodating the interlock connector IC into the accommodating portion 95, unillustrated two terminals provided inside the interlock connector IC are electrically connected via the shorting pin.

The first part 131 includes two fixing portions 134 projecting toward the outer peripheral side of the opening 132. The two fixing portions 134 are provided at positions respectively corresponding to the two fixing portions 41 of the housing 30. Each fixing portion 134 is provided with a through hole 134a penetrating in the Z-axis direction. The through hole 134a communicates with the collar 42 provided in the fixing portion 41. As shown in

The second shell 140 has a tubular shape. The second shell 140 covers the outer periphery of a part of the holding portion 43 not covered by the second part 135.
The second shell 140 includes a projecting portion 141 projecting toward the side opposite to the holding portion 43 in the Z-axis direction. The projecting portion 141 is provided with a screw hole 141a penetrating in the Y-axis direction. The second shell 140 is fixed to the first shell 130 by fastening a bolt 160 inserted through the through hole 141a into the screw hole 136a of the first shell 130.
Although not shown, a braided member made of metal for collectively covering the two wires 20 is mounted on the outer peripheral surface of the second shell 140 by a crimp ring.
The third shell 150 is in the form of a flat plate extending in an XY plane. The third shell 150 covers the opening 32 of the tubular portion 31 and the opening 132 of the first shell 130. In this way, the cover 70 is covered by the third shell 150 from the side opposite to the case 200 in the Z-axis direction.
As shown in
As shown in
The third shell 150 includes a boss insertion hole 152, into which the boss 83 of the cover 70 is inserted. A diameter of the boss insertion hole 152 is larger than that of the boss 83. The diameter of the boss insertion hole 152 is smaller than that of the washer of the aforementioned tap screw 170. Note that, as shown in
As shown in
From the above, gaps are respectively provided between the boss 83 and the boss insertion hole 152, between the first supporting protrusion 84 and the first insertion hole 153 and between the second supporting protrusion 85 and the second insertion hole 154. The third shell 150 is configured to be swingable in a direction orthogonal to the Z-axis direction with respect to the cover 70 within the ranges of these gaps. In this way, the worker can easily align the positions of the through holes 151 and the screw holes 133a.
Functions and effects of this embodiment are described.
According to this configuration, for example, if a liquid such as water intrudes into the inner peripheral side of the inner wall 86 through the gap between the third shell 150 and the cover 70, this liquid is easily discharged to the outer peripheral side of the inner wall 86 through the inner discharge port 88. Further, if a liquid intrudes into the inner peripheral side of the outer wall 89, this liquid is easily discharged to the outer peripheral side of the outer wall 89 through the outer discharge port 90. Here, the inner discharge port 88 is facing the inner peripheral surface of the outer wall 89, and the outer discharge port 90 is facing the outer peripheral surface of the inner wall 86. Thus, for example, if the liquid intrudes into the inner peripheral side of the outer wall 89 through the outer discharge port 90, this liquid is less likely to directly reach the inner discharge port 88. In this way, the liquid is less likely to intrude into the inner peripheral side of the inner wall 86. From the above, the stay of the liquid on the breathable film 100 can be suppressed.
According to this configuration, as shown in
According to this configuration, the first extending portion 87a extends obliquely downward in the connector C1 arranged in such a posture that the outer discharge port 90 is open downward in the vertical direction as in this embodiment. In this way, the liquid having intruded into the inner peripheral side of the inner wall 86 flows obliquely downward along the first extending portion 87a after reaching the first extending portion 87a by the weight thereof. In this way, the liquid having intruded into the inner peripheral side of the inner wall 86 is easily discharged to the outer peripheral side of the inner wall 86 through the inner discharge port 88. Therefore, the effect of suppressing the stay of the liquid on the breathable film 100 can be made even more noticeable.
According to this configuration, the outer discharge port 90 is covered by the first shell 130 from the outer peripheral side of the outer wall 89. In this way, the liquid is less likely to intrude from the outer peripheral side to the inner peripheral side of the outer wall 89 through the outer discharge port 90. Therefore, the liquid can be suppressed from reaching the breathable film 100.
According to this configuration, since the separation wall 91 is located between the two terminals 10 adjacent to each other, these two terminals 10 can be suitably insulated from each other. Further, an insulation distance between the two terminals 10 can be reduced as compared to the case of using the cover body 80 not including the separation wall 91. Therefore, it is possible to suppress an increase in the size of the connector C1 in the parallel direction of the two terminals 10, i.e. the X-axis direction.
According to this configuration, if the cover 70 is inserted into the tubular portion 31 while being inverted about the center axis of the tubular portion 31 with respect to the proper posture, the insertion of the cover 70 into the tubular portion 31 is restricted by the contact of the first coupling wall 93 with the terminal 10. In this way, the worker easily notices the erroneous assembling of the cover 70 with the tubular portion 31.
According to this configuration, the separation wall 91 and the facing wall 92 are coupled by both the first coupling wall 93 and the second coupling wall 94. The second coupling wall 94 is located between the first coupling wall 93 and the second extending portion 12 of the terminal 10. From these, the separation wall 91 and the facing wall 92 can be improved in strength while the interference of the second coupling wall 94 and the terminal 10 is avoided.
According to this configuration, since the holding portion 43 and the tubular portion 31 are coupled by the rib 45, the tilt of the holding portion 43 with respect to the tubular portion 31 can be suppressed.
According to this configuration, during the injection molding of the housing 30, a part of the mold M is arranged in a space where the recess 46 is to be formed, and the resin material for constituting the housing 30 is filled around this part. Thus, the rib 45 is cooled, for example, by causing a refrigerant to flow inside the part of the mold M. Since the rib 45 can be solidified earlier than other parts in this way, the tilt of the holding portion 43 with respect to the tubular portion 31 can be suppressed. Therefore, a reduction in the dimensional accuracy of the housing 30 can be suppressed.
According to this configuration, an increase in the size of the housing 30 in the Y-axis direction can be suppressed, for example, as compared to the case where the terminals 10 and the interlock connector IC are arranged in parallel in the Y-axis direction orthogonal to the parallel direction of the two terminals 10.
According to this configuration, since the first partition wall 33 is provided inside the tubular portion 31, an insulation distance between the terminals 10 and the interlock connector IC can be reduced as compared to the case where the first partition wall 33 is not provided. Therefore, an increase in the size of the connector C1 in the X-axis direction can be suppressed.
This embodiment can be modified and carried out as follows. This embodiment and the following modifications can be carried out in combination without technically contradicting each other.
