Summary of the Invention

Problems to be Solved by the Invention

[0004] When a plurality of lips are formed on the inner peripheral surface of the electric wire insertion hole, as shown in FIG. 9 of the present disclosure, at least one of the molds 91 and 92 for molding the rubber stopper must be formed with a constricted portion 93 so as to correspond to the shape of the lip 90. Therefore, when the mold is removed after molding the rubber stopper, the large-diameter portion 93A of the constricted portion 93 may be caught by the lip 90, and there is a risk that the lip 90 cannot be properly molded.

[0005] Therefore, the present disclosure provides a technique capable of facilitating the molding of the lip.

Means for Solving the Problems

[0006] The connector of the present disclosure includes a housing and a rubber plug attached to the housing. The rubber plug has a plurality of rubber plug members configured separately from each other and arranged side by side in the front-rear direction, and a seal hole penetrating through the plurality of rubber plug members in the front-rear direction. The inner peripheral surface of the seal hole has at least one lip protruding inward, and the number of the lips formed on each of the rubber plug members is at most one.

Advantages of the Invention

[0007] According to the present disclosure, it is possible to facilitate the formation of the lip.

Modes for Carrying Out the Invention

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described. The connector of the present disclosure is (1) A housing and a rubber stopper attached to the housing, the rubber stopper including a plurality of rubber stopper members configured separately from each other and arranged side by side in the front-rear direction, and a seal hole penetrating the plurality of rubber stopper members in the front-rear direction. The inner peripheral surface of the seal hole has at least one lip protruding inward, and the number of the lips formed on each of the rubber stopper members is at most one.

[0010] The above connector is configured with a rubber stopper formed by a plurality of rubber stopper members that are separate from each other, and the number of lips formed on each rubber stopper member is at most one. Therefore, since this lip can be molded without forming a constricted portion in the mold, the mold is less likely to get caught during demolding, making it easy to mold. Note that the shape of the lip is not particularly limited and may be a mountain shape in a side cross-section, or may be a shape obtained by cutting a part (for example, half) of the mountain shape with a plane orthogonal to the front-rear direction.

[0011] (2) The seal hole is constituted by divided seal holes each of the plurality of rubber stopper members has. At least one of the plurality of rubber stopper members has the lip provided at one end in the front-rear direction in the divided seal hole, and the inner diameter of the edge of one end of the divided seal hole may be smaller than the inner diameter of the edge of the other end.

[0012] According to the above connector, even in a configuration where one lip is formed by one mold, by pulling out the mold from the other side in the front-rear direction, the mold is less likely to get caught by the lip, making it easy to mold the lip.

[0013] (3) The at least one rubber stopper member may be arranged such that a portion where the inner diameter of the divided seal hole is minimum is located on the other side rather than the edge of one end.

[0014] According to the above connector, it is easy to form a curved surface at the tip of the lip.

[0015] (4) The rubber stopper has a plurality of the rubber stopper members each having one of the lips, and the inner peripheral surface of the seal hole may have a plurality of the lips.

[0016] According to the above connector, a plurality of lips can be provided on the inner peripheral surface of the seal hole by combining a plurality of rubber stopper members each having one lip. That is, even in a configuration in which a plurality of lips are provided on the inner peripheral surface of the seal hole, since it is not necessary to form a constricted portion in the mold for molding each rubber stopper member, it is easier to mold compared to the conventional configuration in which a constricted portion has to be formed.

[0017] (5) The seal hole is constituted by divided seal holes each of the plurality of the rubber stopper members has, the plurality of the lips have a first lip and a second lip, the plurality of the rubber stopper members have a first rubber stopper member having the first lip, a second rubber stopper member having the second lip, and a third rubber stopper member disposed between the first rubber stopper member and the second rubber stopper member, and the minimum inner diameter of the divided seal hole in the third rubber stopper member may be larger than the minimum inner diameter of the divided seal hole in the second rubber stopper member.

[0018] According to the above connector, the second lip can be more reliably brought into close contact with the electric wire inserted into the seal hole.

[0019] (6) The hardness of the third rubber stopper member may be higher than the hardness of the second rubber stopper member.

[0020] According to the above connector, when inserting the electric wire into the seal hole from the second rubber stopper member side, the movement of the second rubber stopper member is more strongly restricted by the third rubber stopper member, and the second lip is more likely to elastically deform so as to enter the inside of the divided seal hole in the third rubber stopper member. Therefore, according to the above connector, the insertion force of the electric wire can be reduced.

[0021] (7) The inner diameter of the divided seal hole in the third rubber stopper member may be constant in the front-rear direction.

[0022] According to the above connector, the mold for molding the third rubber plug member is easy to remove.

[0023] (8) The housing has a first housing member and a second housing member that are locked to each other, and the plurality of rubber plug members may be arranged in a state of being compressed in the front-rear direction between the first housing member and the second housing member when the first housing member and the second housing member are locked to each other.

[0024] According to the above connector, by inserting the electric wire into the seal hole before the first housing member and the second housing member are locked to each other, the insertion force can be reduced. Then, by locking the first housing member and the second housing member to each other, the plurality of rubber plug members can be compressed in the front-rear direction, and the waterproof property by the rubber plug can be improved.

A plurality of cavities 24 are provided at intervals in the width direction and the height direction of the terminal accommodation portion 20. The terminal fitting 70 is inserted into the cavity 24 from the rear.

[0031] The connector 10 includes a terminal fitting 70. As shown in FIG. 8, the terminal fitting 70 is of the female type. The terminal fitting 70 has conductivity. The terminal fitting 70 is formed by bending a metal plate or the like.

The rubber stopper 12 is positioned by these positioning pins. The outer peripheral surface of the rubber stopper 12 is in close contact with the inner peripheral surface of the rubber stopper housing portion 21. The rubber stopper 12 housed in the rubber stopper housing portion 21 comes into contact with the rear end portion of the terminal housing portion 20, thereby restricting forward movement.

[0033] As shown in Fig. 8, the locking receiving portions 22 are provided on both sides in the width direction of the rubber stopper housing portion 21. The locking receiving portions 22 are formed to project outward in the width direction from the rear end portion of the rubber stopper housing portion 21.

[0036] As shown in Fig. 2, the hood portion 31 is formed to project forward in a cylindrical shape from the outer peripheral portion of the rear wall portion 30.

[0037] As shown in FIG. 7, the temporary locking portion 32 is provided on both sides in the width direction on the rear end side of the hood portion 31. The temporary locking portion 32 has a long slit shape in the height direction. The temporary locking portion 32 locks the locking receiving portion 22 of the first housing member 11A. When the temporary locking portion 32 locks the locking receiving portion 22, the first housing member 11A is in a temporarily locked state with respect to the second housing member 11B.

[0038] As shown in FIG. 8, the main locking portion 33 is provided on both sides in the width direction of the hood portion 31 behind the temporary locking portion 32. The main locking portion 33 has a long slit shape in the height direction. The main locking portion 33 locks the locking receiving portion 22 of the first housing member 11A. When the main locking portion 33 locks the locking receiving portion 22, the first housing member 11A is in a main locked state with respect to the second housing member 11B.

[0039] <Configuration of the rubber stopper 12> As shown in FIG. 2, the rubber stopper 12 is an integrated rubber stopper having a plurality of seal holes 40. As shown in FIG. 3, the rubber stopper 12 includes a first rubber stopper member 12A, a second rubber stopper member 12B, and a third rubber stopper member 12C. The first rubber stopper member 12A, the second rubber stopper member 12B, and the third rubber stopper member 12C are configured as separate bodies and are arranged side by side in the front-rear direction. The second rubber stopper member 12B is arranged behind the first rubber stopper member 12A. The third rubber stopper member 12C is arranged between the first rubber stopper member 12A and the second rubber stopper member 12B. The first rubber stopper member 12A, the second rubber stopper member 12B, and the third rubber stopper member 12C each have a thickness in the front-rear direction and have a long plate shape in the width direction.

[0040] As shown in FIGS. 3 and 4, the seal hole 40 penetrates all of the first rubber plug member 12A, the second rubber plug member 12B, and the third rubber plug member 12C in the front-rear direction. The first rubber plug member 12A has a first divided seal hole 40A. The second rubber plug member 12B has a second divided seal hole 40B. The third rubber plug member 12C has a third divided seal hole 40C. The seal hole 40 is composed of the first divided seal hole 40A, the second divided seal hole 40B, and the third divided seal hole 40C.

[0041] As shown in FIGS. 3 and 4, the rubber plug 12 has a pin insertion hole 41. The pin insertion hole 41 penetrates all of the first rubber plug member 12A, the second rubber plug member 12B, and the third rubber plug member 12C in the front-rear direction. The first rubber plug member 12A has a first divided insertion hole 41A. The second rubber plug member 12B has a second divided insertion hole 41B. The third rubber plug member 12C has a third divided insertion hole 41C. The pin insertion hole 41 is composed of the first divided insertion hole 41A, the second divided insertion hole 41B, and the third divided insertion hole 41C.

[0042] As shown in FIGS. 3 and 4, the rubber plug 12 has an outer peripheral lip 42. The outer peripheral lip 42 is formed over the entire circumference of the outer peripheral surface of the rubber plug 12. The first rubber plug member 12A has a first outer peripheral lip 42A. The first outer peripheral lip 42A is formed over the entire circumference of the outer peripheral surface of the first rubber plug member 12A. The second rubber plug member 12B has a second outer peripheral lip 42B. The second outer peripheral lip 42B is formed over the entire circumference of the outer peripheral surface of the second rubber plug member 12B. The third rubber plug member 12C has a third outer peripheral lip 42C. The third outer peripheral lip 42C is formed over the entire circumference of the outer peripheral surface of the third rubber plug member 12C. The outer peripheral lip 42 is composed of the first outer peripheral lip 42A, the second outer peripheral lip 42B, and the third outer peripheral lip 42C.

[0043] As shown in FIGS. 4 and 5, the inner peripheral surface of the seal hole 40 has a first lip 43 and a second lip 44. The first lip 43 and the second lip 44 each project inside the seal hole 40 and are formed over the entire circumference of the seal hole 40.

[0044] As shown in FIG. 5, the first lip 43 is provided in the first divided seal hole 40A of the first rubber plug member 12A. The first lip 43 is provided at the rear end of the first divided seal hole 40A. For this reason, the inner diameter of the rear end edge of the first divided seal hole 40A is smaller than the inner diameter of the front end edge of the first divided seal hole 40A. The tip 43A of the first lip 43 is disposed in front of the rear end edge of the first divided seal hole 40A. For this reason, the portion 43B where the inner diameter of the first divided seal hole 40A is the smallest is disposed in front of the rear end edge of the first divided seal hole 40A. According to this configuration, it is easy to form a curved surface at the tip of the first lip 43. The shape of the first lip 43 is asymmetric in the front-rear direction. The first lip 43 has a shape like a part of a general mountain-shaped lip cut in a plane orthogonal to the front-rear direction. The first lip 43 has a first front inclined surface 43C, a first rear inclined surface 43D, and a first flat surface 43E. The first front inclined surface 43C expands forward from the tip 43A of the first lip 43. The first rear inclined surface 43D expands rearward from the tip 43A of the first lip 43. The first flat surface 43E extends radially outward from the rear end edge of the first rear inclined surface 43D and is constituted by the rear surface of the first rubber plug member 12A.

[0045] As shown in FIG. 5, the second lip 44 is provided in the second split seal hole 40B of the second rubber plug member 12B. The second lip 44 is provided at the front end portion of the second split seal hole 40B. For this reason, the inner diameter of the front end edge of the second split seal hole 40B is smaller than the inner diameter of the rear end edge of the second split seal hole 40B. The tip 44A of the second lip 44 is disposed rearward of the front end edge of the second split seal hole 40B. For this reason, the portion 44B where the inner diameter of the second split seal hole 40B is minimum is disposed rearward of the front end edge of the second split seal hole 40B. According to this configuration, it is easy to form a curved surface at the tip portion of the second lip 44. The shape of the second lip 44 is asymmetric in the front-rear direction. The second lip 44 has a shape like a part of a generally mountain-shaped lip cut in a plane orthogonal to the front-rear direction. The second lip 44 has a second rear inclined surface 44C, a second front inclined surface 44D, and a second flat surface 44E. The second rear inclined surface 44C has a form that expands rearward from the tip 44A of the second lip 44. The second front inclined surface 44D has a form that expands forward from the tip 44A of the second lip 44. The second flat surface 44E has a form that spreads radially outward from the front end edge of the second front inclined surface 44D and is constituted by the front surface of the second rubber plug member 12B.

[0046] No lip is provided in the third split seal hole 40C of the third rubber plug member 12C. The inner diameter of the third split seal hole 40C is constant in the front-rear direction. According to this configuration, it is easy to remove the mold for molding the third rubber plug member 12C. The inner diameter of the third split seal hole 40C is larger than the minimum inner diameter of the first split seal hole 40A and smaller than the maximum inner diameter of the first split seal hole 40A. The inner diameter of the third split seal hole 40C is larger than the minimum inner diameter of the second split seal hole 40B and smaller than the maximum inner diameter of the second split seal hole 40B. The third rubber plug member 12C has a higher hardness than either the first rubber plug member 12A or the second rubber plug member 12B.

[0047] The minimum inner diameter of the first split seal hole 40A, the minimum inner diameter of the second split seal hole 40B, and the inner diameter of the third split seal hole 40C are all smaller than the outer diameter of the coating 82 of the electric wire 80. Therefore, when the electric wire 80 is inserted into the seal hole 40, the inner peripheral surfaces of the first split seal hole 40A, the second split seal hole 40B, and the third split seal hole 40C are in close contact with the outer peripheral surface of the electric wire 80.

[0048] As described above, the rubber plug 12 is configured by overlapping the first rubber plug member 12A, the second rubber plug member 12B, and the third rubber plug member 12C. And, the rubber plug 12 has a configuration having two lips by providing one lip on each of the first rubber plug member 12A and the second rubber plug member 12B. For this reason, the first lip 43 of the first rubber plug member 12A and the second lip 44 of the second rubber plug member 12B can be formed without forming a constricted portion in the molding die. That is, the connector 10 has a configuration in which the first lip 43 and the second lip 44 are easily formed.

[0049] Also, even in a configuration in which a recess 87 is formed as in the die 85 shown in FIG. 6, since the inner diameter of the rear edge of the first split seal hole 40A is smaller than the inner diameter of the front edge, by pulling out the die from the front, the die is less likely to be caught by the first lip 43. Thus, when the first lip 43 of the first rubber plug member 12A is formed by the dies 85 and 86, since the die 85 forms the entire first split seal hole 40A, the shape of the die 86 can be simplified, and moreover, the surface of the first lip 43 can be easily formed smoothly.

[0050] <Assembly of Connector 10> First, the seal ring 13 is attached to the outer peripheral surface of the first housing member 11A. Then, the retainer 14 is temporarily locked to the first housing member 11A, and the front member 15 is attached. Also, a slider 16 and a lever 17 are attached to the second housing member 11B.

[0051] In the rubber plug housing portion 21 of the first housing member 11A, a rubber plug 12 is housed. The rubber plug 12 is positioned by inserting the pin insertion hole 41 through a positioning pin (not shown) of the rubber plug housing portion 21. As shown in FIG. 7, the first housing member 11A is inserted forward into the hood portion 31 of the second housing member 11B. During the process of inserting the first housing member 11A, the locking receiving portion 22 of the first housing member 11A is pressed against the inner peripheral surface of the hood portion 31 and bends inward in the width direction. When it reaches the temporary locking portion 32, it returns to its original shape by the elastic force. As a result, the locking receiving portion 22 of the first housing member 11A is locked to the temporary locking portion 32 of the second housing member 11B, and the first housing member 11A is in a temporarily locked state with respect to the second housing member 11B.

[0052] In the temporarily locked state, the rubber plug 12 is disposed in the front-rear direction between the rear end portion of the terminal housing portion 20 of the first housing member 11A and the front end portion of the rear wall portion 30 of the second housing member 11B. The distance between the rear end portion of the terminal housing portion 20 of the first housing member 11A and the front end portion of the rear wall portion 30 of the second housing member 11B is larger than the thickness of the rubber plug 12 in the temporarily locked state. Therefore, in the temporarily locked state, the rubber plug 12 is not compressed in the front-rear direction. In this state, the terminal fitting 70 connected to the electric wire 80 is inserted rearward through the through hole 30A of the second housing member 11B and also through the seal hole 40 disposed in front of the through hole 30A. Since the rubber plug 12 is not compressed in the front-rear direction, the frictional force acting on the terminal fitting 70 and the electric wire 80 can be kept small. That is, according to this configuration, the insertion force of the terminal fitting 70 and the electric wire 80 can be reduced.

[0053] Also, the inner diameter of the third divided seal hole 40C is larger than the minimum inner diameter of the second divided seal hole 40B. According to this configuration, the second lip 44 can be more reliably brought into close contact with the electric wire 80 inserted into the seal hole 40.

[0054] Furthermore, the hardness of the third rubber plug member 12C is higher than that of the second rubber plug member 12B. According to this configuration, when the terminal fitting 70 and the electric wire 80 are inserted into the seal hole 40 from the rear, the movement of the second rubber plug member 12B forward is more strongly restricted by the third rubber plug member 12C. Therefore, the second lip 44 is more likely to elastically deform so as to enter the inside of the third divided seal hole 40C. Accordingly, according to this configuration, the insertion force of the terminal fitting 70 and the electric wire 80 can be reduced.

[0055] The terminal fitting 70 is inserted into the cavity 24 of the terminal housing portion 20. When the terminal fitting 70 is disposed in the cavity 24, the outer peripheral surface of the electric wire 80 is in close contact with the inner peripheral surface of the seal hole 40.

[0056] After the terminal fitting 70 is disposed in the cavity 24 and the electric wire 80 is disposed in the seal hole 40, the first housing member 11A is inserted into the back side of the hood portion 31. As a result, the locking receiving portion 22 of the first housing member 11A is disengaged from the temporary locking portion 32 of the second housing member 11B and is locked to the main locking portion 33. Thereby, the first housing member 11A is in the main locked state with respect to the second housing member 11B. In the main locked state, the distance between the rear end portion of the terminal housing portion 20 of the first housing member 11A and the front end portion of the rear wall portion 30 of the second housing member 11B is smaller than the thickness of the rubber plug 12. For this reason, in the main locked state, the rubber plug 12 is compressed in the front-rear direction by the rear end portion of the terminal housing portion 20 of the first housing member 11A and the front end portion of the rear wall portion 30 of the second housing member 11B. Thereby, the inner peripheral surface of the seal hole 40 and the outer peripheral surface of the electric wire 80 in the rubber plug 12 are more strongly in close contact with each other, and the waterproof property by the rubber plug 12 is improved.

[0057] Thereafter, the cover 18 is attached to the second housing member 11B, and the connector 10 is completed.
