[0006] Patent Document 2: Japanese Patent Application Publication No. 2013-54899 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] In the case where multiple lips are formed on the inner circumferential surface of the wire insertion hole, as disclosed herein... Figure 9 As shown, at least one of the molds 91 and 92 that form the rubber plug must have a necked neck 93 formed in a manner corresponding to the shape of the lip 90. Therefore, when the rubber plug is removed from the mold after forming, the large diameter portion 93A of the necked neck 93 may become stuck in the lip 90, preventing the lip 90 from being formed smoothly.

[0009] Therefore, this disclosure provides a technique that can easily shape lips.

[0010] Solution for solving the problem

[0011] The connector disclosed herein comprises a housing and a rubber plug, the rubber plug being assembled to the housing, the rubber plug having: a plurality of rubber plug components, separately configured and arranged in a front-rear direction; and a sealing hole extending through the plurality of rubber plug components in the front-rear direction, the inner peripheral surface of the sealing hole having at least one lip protruding inward, the number of lips formed on each of the rubber plug components being at most one.

[0012] Invention Effects

[0013] According to this disclosure, the lips can be easily shaped. Attached Figure Description

[0023] [Description of embodiments of this disclosure]

[0024] First, embodiments of this disclosure will be described.

[0025] The connector disclosed herein,

[0026] (1) The device comprises a housing and a rubber plug, the rubber plug being assembled in the housing, the rubber plug having: a plurality of rubber plug components, which are separately formed and arranged in a front-rear direction; and a sealing hole that penetrates the plurality of rubber plug components in the front-rear direction, the inner circumferential surface of the sealing hole having at least one lip protruding inward, and the number of the lips formed in each of the rubber plug components being at most one.

[0027] The connector described above consists of multiple rubber plug components that are separately constructed from each other, with a maximum of one lip formed on each rubber plug component. Therefore, the lip can be formed even without forming a neck in the mold, making it less likely for the mold to snag during demolding and easier to form. Furthermore, the shape of the lip is not particularly limited; in a side sectional view, it can be a mountain-shaped shape or a shape in which a portion (e.g., half) of a mountain-shaped shape is cut off with a plane orthogonal to the front-back direction.

[0028] (2) Alternatively, the sealing hole is formed by the segmented sealing holes of each of the multiple rubber plug components, and at least one of the multiple rubber plug components is provided with the lip at one end of the segmented sealing hole in the front-back direction, and the inner diameter of the end edge of the end of the segmented sealing hole on one side is smaller than the inner diameter of the end edge of the other side.

[0029] According to the connector described above, in the structure of forming the lip with a mold, the mold is also pulled out from the other side in the front-back direction, so that the mold is not easily hooked onto the lip, and thus the lip is easily formed.

[0030] (3) Alternatively, in at least one of the rubber plug components, the portion with the smallest inner diameter of the dividing sealing hole is positioned closer to the other side than the end edge of the end on one side.

[0031] According to the connector described above, a curved surface can easily be formed at the tip of the lip.

[0032] (4) Alternatively, the rubber plug may have a plurality of rubber plug components forming a lip, and the inner circumferential surface of the sealing hole may have a plurality of the lips.

[0033] According to the connector described above, by combining multiple rubber plug components that each have a lip, multiple lips can be provided on the inner circumferential surface of the sealing hole. That is, even in a structure where multiple lips are provided on the inner circumferential surface of the sealing hole, it is not necessary to form a neck in the mold for forming each rubber plug component, thus making it easier to form compared to existing structures that have to form a neck.

[0034] (5) Alternatively, the sealing hole may be formed by the segmented sealing holes of the plurality of rubber plug components, the plurality of lips having a first lip and a second lip, the plurality of rubber plug components having: a first rubber plug component having the first lip; a second rubber plug component having the second lip; and a third rubber plug component disposed between the first rubber plug component and the second rubber plug component, wherein the minimum inner diameter of the segmented sealing hole in the third rubber plug component is greater than the minimum inner diameter of the segmented sealing hole in the second rubber plug component.

[0035] According to the connector described above, the second lip can be more reliably fitted to the wire inserted into the sealing hole.

[0036] (6) Alternatively, the hardness of the third rubber plug component may be higher than that of the second rubber plug component.

[0037] According to the connector described above, when the wire is inserted into the sealing hole from the side of the second rubber plug member, the movement of the second rubber plug member is more strongly restricted by the third rubber plug member, and the second lip easily deforms elastically to enter the inner side of the segmented sealing hole in the third rubber plug member. Therefore, according to the connector described above, the insertion force of the wire can be reduced.

[0038] (7) Alternatively, the inner diameter of the segmented sealing hole in the third rubber plug component is constant in the front-back direction.

[0039] According to the connector described above, the mold that forms the third rubber plug component can be easily removed.

[0040] (8) Alternatively, the housing may have a first housing member and a second housing member that are mutually locked together, and a plurality of the rubber plug members are arranged between the first housing member and the second housing member in a compressed state in the front-back direction while the first housing member and the second housing member are mutually locked together.

[0041] According to the connector described above, by inserting the wire into the sealing hole before the first and second housing components interlock, the insertion force can be reduced. Furthermore, by interlocking the first and second housing components, the multiple rubber plug components can be compressed in the front-rear direction, thereby improving the waterproofness of the rubber plug.

[0042] [Details of the embodiments of this disclosure]

[0043] The following description discloses specific examples with reference to the accompanying drawings. Furthermore, the invention is not limited to these examples, but is intended to include all modifications within the meaning and scope equivalent to the claims, as shown by the claims.

[0044] [Implementation Method 1]

[0045] Figure 1 The connector 10 of Embodiment 1 is disclosed. The connector 10 engages with a counterpart connector (not shown). In the following description, the direction in which the connector 10 engages with the counterpart connector is referred to as the front of the connector 10, and the opposite direction is referred to as the rear of the connector 10. Figure 7 and Figure 8 The vertical direction shown is taken as the width direction of connector 10. The direction orthogonal to the front-back direction and the width direction of connector 10 is taken as the height direction of connector 10. Furthermore, in Figures 3-8 In this context, the part before is recorded as "F" and the part after is recorded as "R".

[0046] <Structure of Connector 10>

[0047] Connector 10 is a so-called rod connector. For example... Figure 1 and Figure 2 As shown, connector 10 includes housing 11, rubber plug 12, sealing ring 13, stop body 14, front member 15, slider 16, rod 17 and cover 18.

[0048] <Structure of Shell 11>

[0049] like Figure 2As shown, the housing 11 has a first housing member 11A and a second housing member 11B. The first housing member 11A constitutes an inner housing, and the second housing member 11B constitutes an outer housing. The first housing member 11A and the second housing member 11B are interlocked.

[0050] The first housing component 11A is made of synthetic resin and has insulating properties. For example... Figure 2 and Figure 8 As shown, the first housing member 11A has a terminal storage portion 20, a rubber plug storage portion 21, and a locking receiving portion 22.

[0051] like Figure 8 As shown, the terminal receiving portion 20 has a cavity 24. The cavity 24 is formed to extend in the front-rear direction and is exposed on both the front and rear sides of the first housing member 11A. Multiple cavities 24 are provided at intervals in the width and height directions of the terminal receiving portion 20. A terminal part 70 is inserted into the cavity 24 from the rear.

[0052] Connector 10 includes terminal parts 70. For example... Figure 8 As shown, terminal part 70 is female. Terminal part 70 is conductive. Terminal part 70 is formed by bending a metal plate or the like. Terminal part 70 has a cylindrical (more specifically, square cylindrical) main body 71 and a wire connection part 72. The opposite terminal part (not shown) is electrically connected to the main body 71. The wire connection part 72 is electrically connected to the conductor 81 of the wire 80 by crimping or the like.

[0053] like Figure 8 As shown, the rubber plug receiving portion 21 is formed in a cylindrical shape protruding rearward from the outer periphery of the terminal receiving portion 20. The internal space of the rubber plug receiving portion 21 communicates with the cavity 24 and is exposed at the rear of the first housing member 11A. The rubber plug 12 is received from the rear within the rubber plug receiving portion 21. A positioning pin (not shown) is disposed rearward within the rubber plug receiving portion 21. The rubber plug 12 is positioned by this positioning pin. The outer peripheral surface of the rubber plug 12 is in close contact with the inner peripheral surface of the rubber plug receiving portion 21. The rubber plug 12 received within the rubber plug receiving portion 21 is restricted from forward movement by contacting the rear end of the terminal receiving portion 20.

[0054] like Figure 8 As shown, the locking receiving portion 22 is provided on both sides of the rubber plug receiving portion 21 in the width direction. The locking receiving portion 22 is shaped to extend outward from the rear end of the rubber plug receiving portion 21 in the width direction.

[0055] The second housing component 11B is made of synthetic resin and has insulating properties. For example... Figure 2 and Figure 8 As shown, the second housing member 11B has a rear wall portion 30, a cover portion 31, a temporary locking portion 32, and a permanent locking portion 33.

[0056] like Figure 8 As shown, the rear wall portion 30 is formed into a wall shape with thickness in the front-rear direction. The rear wall portion 30 has a through hole 30A that extends through the rear wall portion 30 in the front-rear direction. Multiple through holes 30A are provided at intervals in the width and height directions. Terminal parts 70 and wires 80 are inserted into the through holes 30A.

[0057] like Figure 2 As shown, the cover portion 31 is formed in a cylindrical shape that protrudes forward from the outer periphery of the rear wall portion 30.

[0058] like Figure 7 As shown, temporary locking portions 32 are provided on both sides of the rear end side of the cover portion 31 in the width direction. The temporary locking portions 32 are formed in the shape of a slit that is long in the height direction. The temporary locking portions 32 lock the locking receiving portion 22 of the first housing member 11A. When the temporary locking portions 32 lock the locking receiving portion 22, the first housing member 11A is in a temporarily locked state relative to the second housing member 11B.

[0059] like Figure 8 As shown, the formal locking portion 33 is disposed on both sides of the cover portion 31 in the width direction, further rearward than the temporary locking portion 32. The formal locking portion 33 is formed in the shape of a slit that is longer in the height direction. The formal locking portion 33 locks the locking receiving portion 22 of the first housing member 11A. When the formal locking portion 33 locks the locking receiving portion 22, the first housing member 11A is in a formal locking state relative to the second housing member 11B.

[0060] <Structure of rubber plug 12>

[0061] like Figure 2 As shown, the rubber plug 12 is a general-purpose rubber plug with multiple sealing holes 40. (As...) Figure 3 As shown, the rubber plug 12 has a first rubber plug member 12A, a second rubber plug member 12B, and a third rubber plug member 12C. The first rubber plug member 12A, the second rubber plug member 12B, and the third rubber plug member 12C are separately constructed and arranged in a front-to-back direction. The second rubber plug member 12B is positioned rearward of the first rubber plug member 12A. The third rubber plug member 12C is positioned between the first rubber plug member 12A and the second rubber plug member 12B. The first rubber plug member 12A, the second rubber plug member 12B, and the third rubber plug member 12C each have a thickness in the front-to-back direction, forming a plate-like shape that is longer in the width direction.

[0062] like Figure 3 and Figure 4As shown, the sealing hole 40 penetrates the entirety of the first rubber plug member 12A, the second rubber plug member 12B, and the third rubber plug member 12C in the front-to-back direction. The first rubber plug member 12A has a first segmented sealing hole 40A. The second rubber plug member 12B has a second segmented sealing hole 40B. The third rubber plug member 12C has a third segmented sealing hole 40C. The sealing hole 40 is formed by the first segmented sealing hole 40A, the second segmented sealing hole 40B, and the third segmented sealing hole 40C.

[0063] like Figure 3 and Figure 4 As shown, the rubber plug 12 has a pin insertion through hole 41. The pin insertion through hole 41 extends through the entire first rubber plug component 12A, the second rubber plug component 12B, and the third rubber plug component 12C in the front-to-back direction. The first rubber plug component 12A has a first segmented insertion through hole 41A. The second rubber plug component 12B has a second segmented insertion through hole 41B. The third rubber plug component 12C has a third segmented insertion through hole 41C. The pin insertion through hole 41 is formed by the first segmented insertion through hole 41A, the second segmented insertion through hole 41B, and the third segmented insertion through hole 41C.

[0064] like Figure 3 and Figure 4 As shown, 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 formed by the first outer peripheral lip 42A, the second outer peripheral lip 42B, and the third outer peripheral lip 42C.

[0065] like Figure 4 and Figure 5 As shown, the inner circumferential surface of the sealing hole 40 has a first lip 43 and a second lip 44. The first lip 43 and the second lip 44 are respectively formed to protrude into the inside of the sealing hole 40 and are formed throughout the entire circumference of the sealing hole 40.

[0066] like Figure 5As shown, a first lip 43 is provided in the first segmented sealing hole 40A of the first rubber plug member 12A. The first lip 43 is provided at the rear end of the first segmented sealing hole 40A. Therefore, the inner diameter of the rear end edge of the first segmented sealing hole 40A is smaller than the inner diameter of the front end edge of the first segmented sealing hole 40A. The top tip 43A of the first lip 43 is positioned forward of the rear end edge of the first segmented sealing hole 40A. Therefore, the portion 43B with the smallest inner diameter of the first segmented sealing hole 40A is positioned forward of the rear end edge of the first segmented sealing hole 40A. According to this structure, a curved surface can be easily formed at the top tip of the first lip 43. The shape of the first lip 43 is asymmetrical. The first lip 43 is formed in a plane orthogonal to the front and rear directions, such as cutting off a portion of a typical mountain-shaped lip. 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 is shaped to expand forward from the tip 43A of the first lip 43. The first rear inclined surface 43D is shaped to expand rearward from the tip 43A of the first lip 43. The first flat surface 43E is shaped to expand radially outward from the rear end edge of the first rear inclined surface 43D, and is formed by the rear surface of the first rubber plug member 12A.

[0067] like Figure 5 As shown, a second lip 44 is disposed in the second segmented sealing hole 40B of the second rubber plug member 12B. The second lip 44 is disposed at the front end of the second segmented sealing hole 40B. Therefore, the inner diameter of the front edge of the second segmented sealing hole 40B is smaller than the inner diameter of the rear edge of the second segmented sealing hole 40B. The top tip 44A of the second lip 44 is disposed rearward than the front edge of the second segmented sealing hole 40B. Therefore, the portion 44B with the smallest inner diameter of the second segmented sealing hole 40B is disposed rearward than the front edge of the second segmented sealing hole 40B. According to this structure, a curved surface can be easily formed at the top tip of the second lip 44. The shape of the second lip 44 is asymmetrical. The second lip 44 is formed in a plane orthogonal to the front and rear directions, such as cutting off a portion of a typical mountain-shaped lip. The second lip 44 has a second rearward inclined surface 44C, a second front inclined surface 44D, and a second flat surface 44E. The second rearward inclined surface 44C expands rearward from the tip 44A of the second lip 44. The second front inclined surface 44D expands forward from the tip 44A of the second lip 44. The second flat surface 44E expands radially outward from the front edge of the second front inclined surface 44D, and is formed by the front surface of the second rubber plug member 12B.

[0068] No lip is provided in the third segmented sealing hole 40C of the third rubber plug component 12C. The inner diameter of the third segmented sealing hole 40C is constant in the front-rear direction. This structure allows for easy removal of the mold used to form the third rubber plug component 12C. The inner diameter of the third segmented sealing hole 40C is larger than the minimum inner diameter of the first segmented sealing hole 40A and smaller than the maximum inner diameter of the first segmented sealing hole 40A. The inner diameter of the third segmented sealing hole 40C is larger than the minimum inner diameter of the second segmented sealing hole 40B and smaller than the maximum inner diameter of the second segmented sealing hole 40B. The hardness of the third rubber plug component 12C is higher than that of both the first rubber plug component 12A and the second rubber plug component 12B.

[0069] The minimum inner diameter of the first segmented sealing hole 40A, the minimum inner diameter of the second segmented sealing hole 40B, and the inner diameter of the third segmented sealing hole 40C are all smaller than the outer diameter of the covering portion 82 of the wire 80. Therefore, when the wire 80 is inserted into the sealing hole 40, the inner circumferential surfaces of the first segmented sealing hole 40A, the second segmented sealing hole 40B, and the third segmented sealing hole 40C are in close contact with the outer circumferential surface of the wire 80.

[0070] As described above, the rubber plug 12 is configured such that the first rubber plug member 12A, the second rubber plug member 12B, and the third rubber plug member 12C overlap each other. Furthermore, the rubber plug 12 has a structure with two lips by providing a lip on each of the first rubber plug member 12A and the second rubber plug member 12B. Therefore, 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 neck in the molding die. That is, the connector 10 has a structure that facilitates the forming of the first lip 43 and the second lip 44.

[0071] In addition, even in such Figure 6 In the structure of the mold 85 shown, which has a recess 87, the inner diameter of the rear end edge of the first dividing sealing hole 40A is smaller than the inner diameter of the front end edge. Therefore, by pulling the mold out from the front, the mold is less likely to get stuck on the first lip 43. Thus, when the first lip 43 of the first rubber plug member 12A is formed by the molds 85 and 86, the shape of the mold 86 can be simplified because the mold 85 forms the first dividing sealing hole 40A as a whole, and the surface of the first lip 43 can be easily formed smooth.

[0072] Assembly of Connector 10

[0073] First, a sealing ring 13 is fitted onto the outer peripheral surface of the first housing member 11A. Then, a stopper 14 is temporarily engaged on the first housing member 11A, and a front member 15 is fitted. Additionally, a sliding member 16 and a rod 17 are fitted onto the second housing member 11B.

[0074] A rubber plug 12 is housed within the rubber plug receiving portion 21 of the first housing member 11A. The rubber plug 12 is positioned by being inserted through a pin-insertion through-hole 41 by a locating pin (not shown) into the rubber plug receiving portion 21. Figure 7 As shown, the first housing member 11A is inserted into the cover portion 31 of the second housing member 11B from the front. During the insertion of the first housing member 11A, the locking receiving portion 22 of the first housing member 11A is pressed inward in the width direction by the inner peripheral surface of the cover portion 31, and when it reaches the temporary locking portion 32, it returns to its original shape by elastic force. As a result, the locking receiving portion 22 of the first housing member 11A is locked with the temporary locking portion 32 of the second housing member 11B, and the first housing member 11A is in a temporarily locked state relative to the second housing member 11B.

[0075] In the temporary locked state, the rubber plug 12 is positioned in the front-rear direction between the rear end of the terminal receiving portion 20 of the first housing member 11A and the front end of the rear wall portion 30 of the second housing member 11B. The distance between the rear end of the terminal receiving portion 20 of the first housing member 11A and the front end of the rear wall portion 30 of the second housing member 11B is greater than the thickness of the rubber plug 12 in the temporary locked state. Therefore, in the temporary locked state, the rubber plug 12 is not compressed in the front-rear direction. In this state, the terminal part 70, which is connected to the wire 80, is inserted from the rear into the through hole 30A of the second housing member 11B and also into the sealing hole 40 located in front of the through hole 30A. Because the rubber plug 12 is not compressed in the front-rear direction, the frictional force acting on the terminal part 70 and the wire 80 is reduced. In other words, according to this structure, the insertion force of the terminal part 70 and the wire 80 can be reduced.

[0076] Furthermore, the inner diameter of the third segmented sealing hole 40C is larger than the minimum inner diameter of the second segmented sealing hole 40B. This structure allows the second lip 44 to more reliably fit against the wire 80 inserted into the sealing hole 40.

[0077] Furthermore, the hardness of the third rubber plug member 12C is higher than that of the second rubber plug member 12B. According to this structure, when the terminal part 70 and the wire 80 are inserted into the sealing hole 40 from the rear, the forward movement of the second rubber plug member 12B is more strongly restricted by the third rubber plug member 12C, thus the second lip 44 can easily deform elastically to enter the inner side of the third segmented sealing hole 40C. Therefore, according to this structure, the insertion force of the terminal part 70 and the wire 80 can be reduced.

[0078] Terminal component 70 is inserted into cavity 24 of terminal receiving part 20. When terminal component 70 is disposed in cavity 24, the outer peripheral surface of wire 80 becomes tightly attached to the inner peripheral surface of sealing hole 40.

[0079] After the terminal part 70 is disposed within the cavity 24 and the wire 80 is disposed within the sealing hole 40, the first housing member 11A is inserted into the inner side of the cover portion 31. As a result, the locking receiving portion 22 of the first housing member 11A disengages from the temporary locking portion 32 of the second housing member 11B and engages with the permanent locking portion 33. Thus, the first housing member 11A is in a permanent locked state relative to the second housing member 11B. In the permanent locked state, the distance between the rear end of the terminal receiving portion 20 of the first housing member 11A and the front end of the rear wall portion 30 of the second housing member 11B is less than the thickness of the rubber plug 12. Therefore, in the permanent locked state, the rubber plug 12 is compressed in the front-rear direction by the rear end of the terminal receiving portion 20 of the first housing member 11A and the front end of the rear wall portion 30 of the second housing member 11B. As a result, the inner peripheral surface of the sealing hole 40 in the rubber plug 12 and the outer peripheral surface of the wire 80 are more tightly adhered, and the waterproofness of the rubber plug 12 is improved.

[0080] Then, the connector 10 is completed by assembling the cover 18 on the second housing member 11B.
