In the figure, reference numeral 1 is a connector according to the present embodiment, which is one of a pair of connectors which are connector assemblies. The connector 1 is preferably a cable connector, used in a state of being connected to the tip of the cable 91, and fitted to a mating connector 101 described later as the other of a pair of connectors that are connector assemblies. The counterparty connector 101 is, for example, a personal computer, a smartphone, a tablet terminal, a vehicle navigation device, a vehicle audio device, a vehicle sensor, an in-vehicle camera, a vehicle light, an electric device such as a vehicle control device, an electronic device, or the like. Although it is a connector attached to a device, it may be attached to any kind of device. For convenience of illustration, the cable 91 is drawn only in a portion close to the tip thereof, and drawing of other portions is omitted.

Further, the cable 91 may be any kind of cable, a coaxial cable, a twisted pair cable, or the like, but here, as shown in FIG. 2, it has two parallel electric wires 93. It will be described as a biaxial cable. In the cable 91, the circumference of the conductive first core wire 94a is coated with the insulating inner covering member 95, and the circumference of the conductive second core wire 94b is coated with the insulating inner covering member 95. The first electric wire 93a and the second electric wire 93b arranged in parallel with the second electric wire 93b are integrally covered with an insulating outer covering member 92. As shown in FIG. 2, it is assumed that the portion within a predetermined length range from the tips of the first core wire 94a and the second core wire 94b is exposed with the inner covering member 95 removed. Further, when the first core wire 94a and the second core wire 94b are described in an integrated manner, the core wire 94 is described, and when the first electric wire 93a and the second electric wire 93b are described in an integrated manner, the electric wire 93 is described. do.

Here, the cable 91 and the connector 1 may be for supplying electric power or for transmitting a signal. Further, the connector 1 will be described, for example, as having a small outer diameter (outer diameter of the rear sleeve 12) of about 3.0 [mm].

In the present embodiment, the expressions used to explain the configuration and operation of each part of the connector 1 and the mating connector 101 and indicating the directions such as lower, left, right, front, and rear are absolute. It is not a thing but a relative one, and is appropriate when each part of the connector 1 and the mating connector 101 is in the posture shown in the figure, but when the posture is changed, it is changed according to the change in the posture. Should be interpreted.

The connector 1 is a member formed by punching, pressing, bending, or the like on a conductive metal plate and a front sleeve 11 integrally formed of an insulating material such as a synthetic resin. A shell 61 as an outer conductor portion housed in the front sleeve 11, an intermediate insulator 21 which is a member integrally formed of an insulating material such as synthetic resin and housed in the shell 61, and conductivity. A terminal 51 as a central conductor portion, which is a member integrally formed by punching, pressing, bending, or the like on a plastic metal plate and housed in the intermediate insulator 21, and preferably heat resistant. A member integrally formed of an insulating material such as a synthetic resin having a cap 22 as a lid member arranged on the rear side of the shell 61 and the terminal 51, and an elastomer such as a synthetic resin. A member integrally formed with a sealing member 31 that watertightly seals the rear side of the shell 61, the terminal 51, and the cap 22, and a member integrally formed of an insulating material such as synthetic resin. It is provided with a rear sleeve 12 disposed on the rear side of the sleeve 11.

The front sleeve 11, the cap 22, the seal member 31, and the rear sleeve 12 are members that are integrated with other members by overmold molding (insert molding), and are independently separated from the other members. It should be noted that although it does not exist, it is drawn so as to exist independently in FIG. 2 for convenience of explanation.

As shown in FIG. 5, the shell 61 has a main body portion 63 as a cylindrical outer main body portion and an outer tail portion extending rearward (X-axis negative direction) from the rear end 63r of the main body portion 63. Has a tail portion 62 of. The main body portion 63 is a hollow portion formed by rolling a flat metal plate into a cylindrical shape, and includes a seam 63c extending in the front-rear direction (X-axis direction). The inside of the main body 63 is a columnar internal cavity 61a, and the intermediate insulator 21 and the terminal 51 are housed in the internal cavity 61a.

Further, the main body portion 63 is formed so that a slit 63a extending in the circumferential direction is applied to the seam 63c. The slit 63a is a portion through which a part of the insulating material constituting the front sleeve 11 enters, and is formed so as to penetrate the metal plate constituting the main body portion 63 in the plate thickness direction. It does not exist all around 63. The intermediate insulator 21 and the terminal 51 are housed in a light press-fitted state behind the slit 63a in the internal cavity 61a by a small protrusion 21d provided on the outside of the intermediate insulator 21. That is, the small protrusion 21d as the light press-fitting portion is located behind the slit 63a. A plurality of lock protrusions 64 are formed in the range between the front end 63f and the slit 63a in the main body portion 63 so as to project inward in the radial direction. The lock protrusion 64 engages with a mating shell 161 described later included in the mating connector 101 that fits with the connector 1.

When the mating shell 161 enters the internal cavity 61a from the front end 63f and engages with the lock protrusion 64 protruding inward in the radial direction, the locking protrusion 64 is pushed outward in the radial direction by the mating shell 161. The range between the front end 63f and the slit 63a in the main body 63 is deformed so that the diameter is increased. However, due to the presence of the slit 63a, such deformation is not transmitted behind the slit 63a. Therefore, even if the fixing strength of the intermediate insulator 21 to the shell 61 cannot be increased due to miniaturization, the intermediate insulator 21 housed behind the slit 63a in the internal cavity 61a is the main body portion. It will not be separated from 63.

Further, a notch 65 that is recessed toward the front is formed at the rear end 63r of the main body portion 63. The positioning projection 21c of the intermediate insulator 21 enters and engages with the notch 65. Further, an opening 63b is formed in the vicinity of the rear end 63r of the main body portion 63 so as to penetrate the metal plate constituting the main body portion 63 in the plate thickness direction. A part of the insulating material constituting the cap 22 enters the opening 63b formed so as to penetrate the side wall of the main body portion 63.

The tail portion 62 has a first connection plate 62a and a second connection plate 62b that are orthogonal to each other in the longitudinal direction (X-axis direction) of the connector 1, that is, when viewed from the front-rear direction, in the vicinity of the rear end. The second connecting plate 62b is formed by bending so as to be perpendicular to the first connecting plate 62a. Then, as shown in FIG. 4C, the second core wire 94b exposed at the tip of the second electric wire 93b of the cable 91 with the inner covering member 95 removed is in the front-rear direction on the circumferential surface thereof. At two points orthogonal to each other when viewed from the above, they are in contact with or close to the first connection plate 62a and the second connection plate 62b, respectively, and are connected by a connection means such as soldering. Therefore, even if the range in which the second core wire 94b overlaps with the tail portion 62 is short in the front-rear direction, the second core wire 94b is connected to the first connection plate 62a and the second connection plate 62b at two points on the circumferential surface of the second core wire 94b. Therefore, the second core wire 94b and the tail portion 62 are surely connected to each other and are surely conductive.

Then, the front sleeve 11 is integrally attached to the outside of the shell 61 by overmold molding. As described above, since a part of the insulating material constituting the front sleeve 11 enters the slit 63a of the shell 61, the front sleeve 11 is securely attached to the shell 61. The front sleeve 11 is a substantially cylindrical member and has a columnar internal cavity 11a penetrating in the axial direction, that is, in the front-rear direction, and the shell 61 is in front of the notch 65 in the main body 63. Most of them are housed in the internal cavity 11a. Further, as shown in FIGS. 4A and 4B, the front sleeve 11 extends forward from the front end 63f of the main body 63 of the shell 61, and is rearward from the housing front end 11f in the internal cavity 11a. There is no shell 61 in the predetermined length range of. Further, the central axis of the internal cavity 11a is coaxial with the central axis of the internal cavity 61a of the shell 61, and the inner diameter of the internal cavity 11a is substantially the same as the outer diameter of the shell 61.

As shown in FIG. 6, the intermediate insulator 21 is a member having a substantially cylindrical shape, and has a columnar internal cavity 21a penetrating in the axial direction, that is, in the front-rear direction. A tapered portion 21a1 whose inner diameter increases as it advances forward (in the positive direction of the X-axis) is formed in a portion of the internal cavity 21a in contact with the front end 21f. Further, in the portion of the internal cavity 21a in contact with the rear end 21r, a square hole portion 21a3 having a rectangular cross section is formed. Further, the portion of the internal cavity 21a between the tapered portion 21a1 and the square hole portion 21a3 is a round hole portion 21a2 having a circular cross section and an inner diameter smaller than that of the square hole portion 21a3. The terminal 51 is housed in the internal cavity 21a, the main body 53 of the terminal 51 is housed in the square hole 21a3, and the contact arm portion 54 of the terminal 51 is housed in the round hole 21a2. The tapered portion 21a1 does not have a terminal 51 and functions as an inviting portion for smoothly inserting the tip of the mating terminal 151, which will be described later, included in the mating connector 101 that fits with the connector 1.

Further, a recess 21b is formed in a predetermined length range in front of the rear end 21r of the intermediate insulator 21. The recess 21b is a portion into which a part of the insulating material constituting the cap 22 enters, and is formed so as to be recessed from the outer peripheral surface of the intermediate insulator 21, but the entire intermediate insulator 21 is formed. It does not exist all around. Further, a positioning projection 21c that protrudes rearward and outward in the radial direction is formed in a part of the rear end 21r. The positioning projection 21c projects outward in the radial direction from the outer peripheral surface of the intermediate insulator 21 and enters and engages with the notch 65 of the shell 61.

Then, the intermediate insulator 21 is press-fitted into the internal cavity 61a of the shell 61 from the rear. At this time, the positioning projection 21c enters and engages with the notch 65 of the shell 61 from the rear, whereby the intermediate insulator 21 is positioned with respect to the shell 61 in the front-rear direction and the circumferential direction.

As shown in FIG. 7, the terminal 51 includes a main body portion 53 as a central main body portion having a rectangular tubular cross section, and a pair of contact arm portions 54 extending forward from the main body portion 53. It has a tail portion 52 as a central tail portion extending rearward from the main body portion 53. The main body 53 is a portion made by bending a flat metal plate into a square cylinder, and one of the side walls of the square cylinder is formed with an engaging protrusion 53a protruding outward. .. Further, the base end of the contact arm portion 54 is integrally connected to the front ends of the pair of side walls of the square cylinder facing each other. The contact arm portion 54 functions as a cantilever-shaped leaf spring. The distance between the contact arm portions 54 facing each other is formed so as to become narrower toward the front, and the distance between the contact arm portions 54 at the tip, that is, the free end is preferably the contact portion of the mating terminal 151. It is smaller than the outer diameter of 154. When the connector 1 and the mating connector 101 are fitted, the mating terminal 151 enters between the contact arm portions 54 facing each other and pushes the contact arm portions 54 together, so that the contact arm functions as a cantilever-shaped leaf spring. The portion 54 sandwiches the mating terminal 151 from both sides, whereby the contact between the contact arm portion 54 and the mating terminal 151 is surely maintained and the contact is surely conducted.

The tail portion 52 has a connecting portion 52c integrally connected to the main body portion 53. The connecting portion 52c is a member that connects the rear end of the main body portion 53 and the front end of the tail portion 52, and extends in a direction orthogonal to the front-rear direction (in the example shown in the figure, the Y-axis direction). , Functions as a lid member that closes the rear end of the square tubular main body 53. In the example shown in the figure, the connecting portion 52c bends at a substantially right angle from the rear end of the side wall on which the engaging projection 53a is formed in the square cylinder of the main body portion 53, and the direction of the side wall facing the side wall (Y). It extends in the negative axis direction), and after passing through the facing side wall, it bends at a substantially right angle and is integrally connected to the front end of the tail portion 52 extending in the front-rear direction. In this way, since the rear end of the square cylinder-shaped main body 53 is closed by the connecting portion 52c, the insulating material constituting the cap 22 and the elastomer constituting the sealing member 31 can be formed from the rear end of the square cylinder. It is surely prevented from entering the inside and further entering between the pair of contact arm portions 54.

Further, the tail portion 52 has a first connection plate 52a and a second connection plate 52b that are orthogonal to each other in the longitudinal direction (X-axis direction) of the connector 1, that is, when viewed from the front-rear direction, in the vicinity of the rear end. The second connecting plate 52b is formed by bending so as to be perpendicular to the first connecting plate 52a. Then, as shown in FIG. 4C, the first core wire 94a exposed at the tip of the first electric wire 93a of the cable 91 with the inner covering member 95 removed is in the front-rear direction on the circumferential surface thereof. They are in contact with or close to the first connecting plate 52a and the second connecting plate 52b, respectively, at two locations orthogonal to each other when viewed from the above, and are connected by a connecting means such as soldering. Therefore, even if the range in which the first core wire 94a overlaps with the tail portion 52 is short in the front-rear direction, the first core wire 94a is connected to the first connection plate 52a and the second connection plate 52b at two points on the circumferential surface of the first core wire 94a. Therefore, the first core wire 94a and the tail portion 52 are securely connected to each other and are surely conductive.

Then, the terminal 51 is press-fitted into the internal cavity 21a of the intermediate insulator 21 from the rear. Then, the square tubular main body 53 enters the square hole 21a3 formed in the portion of the internal cavity 21a in contact with the rear end 21r, and a pair of contact arms enter the round hole 21a2 located in front of the square hole 21a3. Part 54 enters. At this time, the inner diameter of the round hole portion 21a2 is smaller than the outer diameter of the main body portion 53, and the portion of the connecting portion 52c near the front end of the tail portion 52 abuts on the rear surface of the positioning projection 21c, so that the main body portion 53 is round. The terminal 51 is positioned with respect to the intermediate insulator 21 in the front-rear direction without entering the hole 21a2. Further, since the square tubular body portion 53 is housed in the square hole portion 21a3, the terminal 51 is positioned with respect to the intermediate insulator 21 in the circumferential direction. Since the engaging projection 53a of the main body 53 bites into the inner wall of the square hole 21a3, the terminal 51 does not displace in the front-rear direction with respect to the intermediate insulator 21. Further, as shown in FIGS. 4A and 4B, the contact arm portion 54 stops in the round hole portion 21a2 and does not enter the tapered portion 21a1.

Further, in a state where the terminal 51 is press-fitted into the internal cavity 21a of the intermediate insulator 21 press-fitted into the internal cavity 61a of the shell 61, the tail portion 52 of the terminal 51 is as shown in FIG. 4A. It extends rearward so as to face the tail portion 62 of the shell 61. Specifically, the tail portion 52 of the terminal 51 is located substantially flush with the cylindrical wall of the cylindrical main body portion 63 of the shell 61 and on the opposite side of the tail portion 62 of the shell 61 in the circumferential direction, and is rearward. It extends to. That is, the tail portion 52 of the terminal 51 and the tail portion 62 of the shell 61 form a part of the cylindrical wall surface having substantially the same diameter as the cylindrical wall surface of the main body portion 63 of the shell 61. Further, in the front-rear direction, the position of the rear end of the tail portion 52 of the terminal 51 is the same as the position of the rear end of the tail portion 62 of the shell 61, and the positions of the first connection plate 52a and the second connection plate 52b of the terminal 51 are the same. The positions are also the same as the positions of the first connection plate 62a and the second connection plate 62b of the shell 61. Then, as shown in FIG. 4C, the first connection plate 52a of the terminal 51 and the first connection plate 62a of the shell 61 face each other, and the second connection plate 52b of the terminal 51 and the second connection plate 62b of the shell 61 face each other. It is almost flush with the connection plate 62b.

In this way, the intermediate insulator 21 is press-fitted into the internal cavity 61a of the shell 61, the terminal 51 is press-fitted into the internal cavity 21a of the intermediate insulator 21, and then the intermediate insulator 21 and the terminal 51 are rearward. The cap 22 is integrally molded as shown in FIGS. 9 and 10 by overmolding. Although the cap 22 is shown independently in FIGS. 9 and 10 for convenience, the cap 22 is in a state where the intermediate insulator 21, the terminal 51, and the shell 61 are placed in a mold for molding. A member that is integrally molded with the intermediate insulator 21, terminal 51, and shell 61 by performing overmold molding (insert molding) in which a dielectric material such as synthetic resin is filled in the mold. Therefore, in reality, it does not exist as a single body having the shape shown in FIGS. 9 and 10.

As a result, the rear end 63r of the main body 63 of the shell 61 that houses the intermediate insulator 21 and the terminal 51 inside, and the shell 61 and the intermediate insulator 21 in the vicinity of the rear end 63r on the outer peripheral surface of the main body 63. The gap existing between the terminal 51 and the terminal 51 is closed by the entry of the insulating material constituting the cap 22. Further, the insulating material constituting the cap 22 enters the opening 63b formed in the main body 63 of the shell 61 through the recess 21b of the intermediate insulator 21 and fills the recess 21b and the opening 63b. By forming the cap 22, it is securely attached to the shell 61 and the intermediate insulator 21. Further, in the main body portion 53 of the terminal 51 housed in the square hole portion 21a3 of the internal cavity 21a of the intermediate insulator 21, the rear end closed by the connecting portion 52c is further closed by the cap 22 from the rear. It does not come out from the square hole portion 21a3.

Specifically, the cylindrical portion 22c of the cap 22 enters the recess 21b of the intermediate insulator 21 located in the internal cavity 61a of the main body portion 63 from the rear end 63r side of the main body portion 63 of the shell 61, and the cylindrical portion 22c. The outer portion 22h located on the outer side in the radial direction enters between the notch 65 of the shell 61 and the positioning projection 21c of the intermediate insulator 21 and covers the positioning projection 21c, and has a radius from the outer surface of the cylindrical portion 22c. The convex portion 22b protruding outward in the direction is in a state of entering the opening 63b of the shell 61. Further, the vicinity of the rear end of the intermediate insulator 21 enters the front cavity 22d formed in the cylindrical portion 22c, and the main body portion 53 of the terminal 51 enters the rear cavity 22e behind the front cavity 22d. The vicinity of the rear end has entered, the vicinity of the front end of the tail portion 62 of the shell 61 has entered the cutout portion 22g on the outer periphery, and the positioning projection 21c has entered the outer cavity 22i in the outer portion 22h.

The concave portion 21b of the intermediate insulator 21 does not cover the entire circumference, and as shown in FIG. 6, a rear convex portion 21e is partially formed. Therefore, as shown in FIG. 10, a concave portion 22m corresponding to the rear convex portion 21e is formed in the cylindrical portion 22c of the cap 22, and as shown in FIGS. 9 and 10, the outer periphery of the intermediate insulator 21 is formed. A thin wall portion 22k that penetrates into a small gap formed between the surface and the inner peripheral surface of the main body portion 63 of the shell 61 is formed. The thin wall portion 22k may not be formed due to the variation in the gap, but even if the thin wall portion 22k is not formed, the waterproof property of the cap 22 is not affected.

By molding the cap 22 by overmolding in this way, the cap 22, the intermediate insulator 21, the shell 61, and the terminal 51 can be reliably integrated even if each member becomes smaller due to miniaturization. can. In addition, FIG. 11 further shows a partially assembled state in which the front sleeve 11 is molded by overmold molding. Further, when the cap 22 is molded by overmold molding, the gate formed on the wall surface of the molding mold (mold) (not shown) is immediately before the rear surface of the cap 22 as shown in FIG. 11 (b). The insulating material that is located and constitutes the cap 22 through the gate is filled into the molding mold, as indicated by the arrow 43, and enters and integrates with each portion. The gate may have only one point, but may have multiple points. For example, the gates 43 and 43a can be provided facing each other on both sides of the cap 22 in the Z-axis direction. As a result, when the insulating material is filled in the molding mold, the pressure of the insulating material acting on the parts in the molding mold is easily made uniform, and the generation of short mold due to the deviation of the parts is suppressed. Will be done. A gate mark 22j remains on the surface of the molded cap 22.

As shown in FIG. 8, the outer peripheral surface of the cap 22 is a circumferential surface that is substantially flush with the outer peripheral surface of the cylindrical main body portion 63 of the shell 61. Further, an umbrella-shaped or mushroom-shaped anchor portion 22a projecting rearward is formed on the rear surface of the cap 22, and a constricted portion 22f is formed between the rear surface of the cap 22 and the anchor portion 22a. The tail portion 62 of the shell 61 is rearward from the boundary portion between the rear surface and the circumferential surface of the cap 22 so that at least the first connection plate 62a and the second connection plate 62b are located behind the anchor portion 22a. It is in a state of being exposed by protruding. Similarly, the tail portion 52 of the terminal 51 is also from the boundary portion between the rear surface and the circumferential surface of the cap 22 so that at least the first connection plate 52a and the second connection plate 52b are located behind the anchor portion 22a. It is in a state of being exposed by protruding backward.

Then, the core wire 94 of the cable 91 is connected to the tail portion 52 of the terminal 51 and the tail portion 62 of the shell 61. Here, the first connection plate 52a and the second connection plate 52b of the tail portion 52 of the terminal 51, and the first connection plate 62a and the second connection plate 62b of the tail portion 62 of the shell 61 are caps 22 in the front-rear direction. The first connection plate 52a of the terminal 51 and the first connection plate 62a of the shell 61 face each other at the same position behind the anchor portion 22a of the terminal 51, and the second connection plate 52b of the terminal 51 and the shell 61. 2 It is almost flush with the connection plate 62b.

Therefore, the first core wire 94a and the second core wire 94b of the cable 91 arranged in parallel in a state where the inner covering member 95 is removed and exposed are combined with the second connection plate 52b and the shell 61 of the terminals 51 arranged in parallel. By simply placing it on the second connection plate 62b, as shown in FIG. 8, the first core wire 94a abuts or is close to the first connection plate 52a and the second connection plate 52b of the tail portion 52 of the terminal 51. In addition, the second core wire 94b is in contact with or close to the first connection plate 62a and the second connection plate 62b of the tail portion 62 of the shell 61. Then, by making a connection such as soldering, two places on the circumferential surface of the first core wire 94a are connected to the first connection plate 52a and the second connection plate 52b, and the circumferential surface of the second core wire 94b is connected. Two places are connected to the first connection plate 62a and the second connection plate 62b. In this way, the first core wire 94a and the second core wire 94b of the cable 91 can be connected to the tail portion 52 of the terminal 51 and the tail portion 62 of the shell 61 with a relatively simple work operation. Therefore, for example, a robot or the like can be used. It can also be used, the assembly work of the connector 1 can be simplified and rationalized, and the production cost can be reduced. Further, two places on the circumferential surface of the first core wire 94a are connected to the first connection plate 52a and the second connection plate 52b, and two places on the circumferential surface of the second core wire 94b are connected to the first connection plate 62a and the second connection plate. Since it is connected to the plate 62b, the first core wire 94a is connected to the tail portion 52 even if the length of the first core wire 94a and the second core wire 94b overlapping with the tail portion 52 and the tail portion 62 is short in the front-rear direction. Since the total length to be formed and the total length to which the second core wire 94b is connected to the tail portion 62 become long, the connection is ensured.

In this way, after the core wire 94 of the cable 91 is connected to the tail portion 52 of the terminal 51 and the tail portion 62 of the shell 61, the terminal 51, the shell 61, and the rear side of the cap 22 are sealed by overmold molding. The member 31 is integrally attached. The elastomer constituting the sealing member 31, which is a material having higher flexibility than the materials of the front sleeve 11, the cap 22, and the rear sleeve 12, exists between the shell 61, the intermediate insulator 21, the terminal 51, and the cap 22. It enters the gap and seals the gap watertightly. Further, the elastomer also covers the tail portion 52 of the terminal 51 exposed behind the cap 22, the tail portion 62 of the shell 61, and the core wire 94 of the cable 91 connected to them without gaps, and is hermetically sealed. Stop. Desirably, as shown in FIG. 4, the sealing member 31 is formed so that the front overlaps with the rear end on the outer peripheral surface of the front sleeve 11 and the vicinity of the rear end in the front-rear direction, and the rear is at least the cap 22. It is formed so as to cover the periphery of each member in the range up to the anchor portion 22a of the above. Further, it may be formed so as to cover the periphery of each member in the range up to the portion close to the front end on the outer peripheral surface of the inner covering member 95 of the electric wire 93 without a gap.

Therefore, the anchor portion 22a of the cap 22 is buried in the seal member 31, and the seal member 31 has entered the periphery of the constricted portion 22f, so that the cap 22 and the seal member 31 are securely coupled. .. Further, the elastomer constituting the seal member 31 has high flexibility and covers the tail portion 52 of the terminal 51, the tail portion 62 of the shell 61, and the core wire 94 of the cable 91 connected to them without a gap. The tail portion 52 of the 51, the tail portion 62 of the shell 61, and the core wire 94 can be reliably waterproofed.

After the seal member 31 is integrally molded by overmold molding, the seal member 31 and the shell 61 can be brought into close contact with each other by reheating, and the waterproof property can be further improved.

Then, on the rear side of the front sleeve 11, the rear sleeve 12 is integrally attached by overmold molding so as to cover the periphery of the electric wire 93 of the seal member 31 and the cable 91. The rear sleeve 12, together with the front sleeve 11, is a member that forms the outermost layer of the connector 1, and is preferably close to the rear end of the front sleeve 11 on the outer peripheral surface in the front-rear direction, as shown in FIG. It is formed so as to cover the periphery of each member in the range from the portion to the portion close to the front end on the outer peripheral surface of the outer covering member 92 of the cable 91 without a gap.

The rear sleeve 12 may have a recess 12b existing over the entire circumference of the outer surface. The recess 12 is used to hook a jig (not shown) when the connector 1 and the mating connector 101 are fitted or disengaged, that is, when the connector 1 is inserted or removed. When the rear sleeve 12 is molded by overmold molding, the gate formed on the wall surface of the molding mold (mold) (not shown) is located immediately after the recess 12b as shown in FIG. 4A. Then, the insulating material constituting the rear sleeve 12 through the gate is filled in the molding mold as indicated by the arrow 41.

It is desirable that the gates face each other on both sides of the rear sleeve 12 in the Y-axis direction. As a result, when the insulating material is filled in the molding mold as shown by the arrow 41, the pressure of the insulating material acting on the parts in the molding mold is easily made uniform, and the pressure of the insulating material is easily equalized. The generation of short molds caused by this is suppressed. Further, the position of the gate is preferably close to the outer covering member 92 in order to improve the weldability between the insulating material constituting the rear sleeve 12 and the outer covering member 92 of the cable 91, but directly under the gate. The presence of the outer covering member 92 is not desirable because the outer covering member 92 is deformed by the injection pressure of the insulating material. Further, it is desirable that the position of the gate is closer to the outer covering member 92 than the recess 12b when the rear sleeve 12 has the recess 12b. If the position of the gate is closer to the front sleeve 11 than the thin recess 12b, the pressure required to fill the insulating material in the molding mold becomes high, and the cable 91 may be deformed. .. Considering these facts, it is desirable that the gate is in a position as shown in FIG. 4 (a). A gate mark 12c remains on the surface of the molded rear sleeve 12.

Further, the insulating material filled in the molding mold overflows and flows out from the molding mold as shown by the arrow 42. It is desirable that the outflow of the insulating material due to the overflow is also performed at the positions facing each other on both sides of the rear sleeve 12 in the Y-axis direction. Due to the overflow of the insulating material, the weldability between the insulating material constituting the rear sleeve 12 and the outer covering member 92 of the cable 91 becomes high, and the waterproofness becomes high. It is desirable that the position where the insulating material flows out is close to the rear end 12r of the rear sleeve 12 in order to improve the weldability between the insulating material and the outer covering member 92. An overflow mark 12d remains on the surface of the molded rear sleeve 12.

Next, the configuration of the mating connector 101 will be described.

In FIG. 17, (a) is a perspective view seen from the front, (b) is a perspective view seen from the rear, (a) is a perspective view seen from the front, and (b) is a side view.

The mating connector 101 is a member formed by punching, pressing, bending, or the like on a conductive metal plate and a mating housing 111 integrally formed of an insulating material such as synthetic resin. The counterpart shell 161 as the counterpart outer conductor portion housed in the counterpart housing 111 and the counterpart shell 161 which is a member integrally formed by punching, pressing, bending, or the like on a conductive metal plate. A member integrally formed of a mating terminal 151 as a mating center conductor portion housed in the housing 111 and an elastomer such as synthetic resin, rubber, or the like, and the rear side of the mating shell 161 and the mating terminal 151 is watertight. The first outer seal member 141 and the second outer seal as an O-ring, which is a member integrally formed of an elastomer such as a synthetic resin and is attached to the outer peripheral surface of the counterpart housing 111. A member 142 is provided.

The mating housing 111 and the mating seal member 131 are members that are integrated with other members by overmolding.

As shown in FIG. 17, the mating shell 161 has a flat plate-shaped main body portion 163 extending in the front-rear direction (X-axis direction) and extending rearward (X-axis positive direction) from the rear end of the main body portion 163. It has an existing flat plate-shaped tail portion 162 and a cylindrical contact portion 164 connected to the front end of the main body portion 163. The tail portion 162 is a flat plate-shaped member wider than the main body portion 163, and is connected to a conductive line such as a connector, a circuit board, or an electric wire provided in a device (not shown) to which the mating connector 101 is mounted. At the front end of the tail portion 162, inclined portions 162a are formed on both sides in the width direction so as to facilitate the transition to the narrow main body portion 163.

Further, the contact portion 164 is a portion made by rolling a flat metal plate into a cylindrical shape, and includes a seam 164c extending in the front-rear direction (X-axis direction). The inside of the contact portion 164 is a columnar internal cavity 164a, and the contact portion 154 of the mating terminal 151 passes through the inside cavity 164a. Further, a recess 164b extending over the entire circumference in the circumferential direction is formed on the outer peripheral surface of the contact portion 164. The recess 164b engages with the lock projection 64 of the shell 61 included in the connector 1 that fits into the mating connector 101. Further, an opening 164d is formed in the vicinity of the rear end of the contact portion 164 so as to penetrate the metal plate constituting the contact portion 164 in the plate thickness direction. A part of the insulating material constituting the mating housing 111 enters the opening 164d.

A curved portion 163a having a substantially crank-shaped side surface shape is formed in the middle of the main body portion 163. As shown in FIG. 17B, the portion of the main body portion 163 other than the curved portion 163a and the tail portion 162 are upward from the cylindrical central axis of the contact portion 164 (Z-axis negative in the example shown in the figure). It is biased in the direction) and extends linearly in the front-back direction. As shown in FIG. 13B, the main body portion 153 of the mating terminal 151 is in the direction opposite to the main body portion 163 and the tail portion 162 with the central axis interposed therebetween (in the example shown in the figure, the Z-axis is positive). It is biased in the direction) and extends linearly in the front-back direction. The curved portion 163a is more biased than the portion of the main body portion 163 other than the curved portion 163a and the tail portion 162. Therefore, since the distance between the curved portion 163a and the main body portion 153 of the mating terminal 151 becomes large, when the mating housing 111 is molded by overmold molding, the insulating material filled in the molding mold (not shown) is used. It flows smoothly through the gap between the curved portion 163a and the main body portion 153 of the mating terminal 151, and is uniformly filled in the entire molding mold.

As shown in FIG. 13, the gate formed on the wall surface of the molding mold (mold) (not shown) is between the curved portion 163a of the main body portion 163 of the mating shell 161 and the main body portion 153 of the mating terminal 151. The insulating material located at the gate and constituting the mating housing 111 is filled in the molding mold as indicated by an arrow 44, and enters and integrates with each portion. The plate thickness of the main body portion 163 of the mating shell 161 is thinner than that of the main body portion 153 of the mating terminal 151, and the curved portion 163a is formed on the thinner plate thickness side to escape from the flow of the insulating material. This makes it possible to prevent deformation of the mating shell 161 and the mating terminal 151 due to the flow of the insulating material during overmold molding.

As shown in FIG. 16, the mating terminal 151 has a flat plate-shaped main body portion 153 extending in the front-rear direction (X-axis direction) and extending rearward (X-axis positive direction) from the rear end of the main body portion 153. It has an existing flat plate-shaped tail portion 152 and a cylindrical contact portion 154 connected to the front end of the main body portion 153. The tail portion 152 is a flat plate-shaped member wider than the main body portion 153, and is connected to a conductive line such as a connector, a circuit board, or an electric wire provided in a device (not shown) to which the mating connector 101 is mounted. Then, the contact portion 154 enters between the contact arm portions 54 facing each other of the terminals 51 included in the connector 1 fitted to the mating connector 101, and is sandwiched from both sides. As a result, the contact between the contact portion 154 of the mating terminal 151 and the contact arm portion 54 of the terminal 51 is reliably maintained, and the contact is reliably maintained. At the front end of the tail portion 152, inclined portions 152a are formed on both sides in the width direction so as to facilitate the transition to the narrow main body portion 153.

Further, in the vicinity of the front end of the main body portion 153, a step portion 153a having a substantially stepped side surface shape is formed. As shown in FIG. 13B, the portion of the main body portion 153 in front of the step portion 153a (in the negative direction of the X axis) and the contact portion 154 substantially coincide with the cylindrical central axis of the contact portion 164 of the mating shell 161. Although it extends linearly in the front-rear direction in this state, the portion of the main body portion 153 behind the step portion 153a (in the positive direction of the X-axis) and the tail portion 152 are located downward from the central axis (shown in the figure). In the example, it is biased in the positive direction of the Z axis) and extends linearly in the front-back direction. As described above, the main body portion 153 and the tail portion 152 are deviated in the direction opposite to the main body portion 163 and the tail portion 162 of the other party shell 161 with the central axis interposed therebetween, so that the main body portion of the other party shell 161 is provided. It does not come into contact with the 163 and the tail portion 162.

Then, with the other party shell 161 and the other party terminal 151 arranged so as to have a positional relationship as shown in FIGS. 13 (b) and 14 (b), the main body portion 163 and the tail portion 162 of the other party shell 161 are arranged. The mating seal member 131 is integrally attached by overmold molding so as to surround the connection portion of the above and the connection portion between the main body portion 153 and the tail portion 152 in the mating terminal 151. The elastomer constituting the mating sealing member 131, which is a material having higher flexibility than the material of the mating housing 111, watertightly seals between the mating shell 161 and the mating terminal 151 and the periphery thereof.

Subsequently, the mating housing 111 is integrally attached by overmolding so as to cover the periphery of the mating shell 161, the mating terminal 151, and the mating sealing member 131. As shown in FIGS. 13 to 15, the mating housing 111 covers the periphery of the mating sealing member 131, and the elastomer constituting the mating sealing member 131 is confined inside. At this time, the inclined portion 162a formed in the connecting portion between the main body portion 163 and the tail portion 162 in the counterpart shell 161 and the inclined portion formed in the connecting portion between the main body portion 153 and the tail portion 152 in the counterpart terminal 151. Since the portion 152a supports the elastomer, the elastomer, which is a highly flexible material, is pushed by the flow of the insulating material when overmolding the mating housing 111, or is pressed from the surroundings by the constituent insulating material. Even if it does, it does not flow out and maintains a state of surrounding the connection portion between the main body portion 163 and the tail portion 162 in the other party shell 161 and the connection portion between the main body portion 153 and the tail portion 152 in the other party terminal 151. be able to.

It is not always necessary to form the inclined portions 152a and 162a in the tail portion 152 of the mating terminal 151 and the tail portion 162 of the mating shell 161. As shown in FIGS. 15 (c) and 15 (d), the tail portion 152 If the mating seal member 131 is arranged so as to cover the front side of the above and 162, the same effect can be obtained even if the inclined portions 152a and 162a are omitted. That is, the mating seal member 131 may surround the periphery of the connecting portion between the main body portion 153 and the tail portion 152 in the mating terminal 151 and the connecting portion between the main body portion 163 and the tail portion 162 in the mating shell 161.

Further, as shown in FIGS. 12 to 15, the mating housing 111 covers the entire main body portion 153 of the mating terminal 151 and the entire contact portion 164 and main body portion 163 of the mating shell 161 in the front-rear direction, and the mating terminal A range of a predetermined length is exposed and protrudes forward (in the negative direction of the X-axis) from the front end 111f of the housing from the tip of the contact portion 154 of 151, and is projected from the rear end of the tail portion 162 of the mating shell 161 and the tail portion 152 of the mating terminal 151. A range of predetermined length is formed so as to be exposed and protrude rearward (X-axis positive direction) from the rear end 111r of the housing. It is desirable that the plate-shaped intervening portion 111b interposed between the tail portion 162 of the mating shell 161 and the tail portion 152 of the mating terminal 151 is formed behind the rear end 111r of the housing. Further, the mating housing 111 is formed so that at least a part of the cylindrical outer peripheral surface of the contact portion 164 of the mating shell 161 is exposed at a portion close to the front end 111f of the housing. Since a part of the insulating material constituting the mating housing 111 enters the opening 164d formed in the contact portion 164, the contact portion 164 is securely attached to the mating housing 111.

Further, in the front-rear direction, a flange portion 111a projecting outward in the radial direction is formed on the outer peripheral surface of the mating housing 111 near the middle between the front end 111f of the housing and the rear end 111r of the housing. The flange portion 111a is a portion attached to the outer wall of a housing provided in a device (not shown) to which the mating connector 101 is mounted, and a portion of the mating connector 101 in front of the flange portion 111a is exposed to the outside of the housing. The portion of the mating connector 101 behind the flange portion 111a is housed inside the housing. Further, on the outer peripheral surface of the mating housing 111, a first concave groove portion 111c is formed over the entire circumference in a portion in front of the flange portion 111a, and a first concave groove portion 111c is formed in a portion behind the flange portion 111a over the entire circumference. 2 The concave groove portion 111d is formed. Then, the first outer seal member 141 is attached to the first concave groove portion 111c, and the second outer seal member 142 is attached to the second concave groove portion 111d. The first outer seal member 141 and the second outer seal member 142 are in a state of protruding outward in the radial direction from the outer peripheral surface of the mating connector 101 before and after the first outer seal member 141.

Further, on the outer peripheral surface of the mating housing 111, a third concave groove portion 111e is formed over the entire circumference in a portion behind the second concave groove portion 111d. In the third concave groove portion 111e, when the mating housing 111 is press-fitted into a hole formed in the outer wall of the housing, the mating housing 111 behind the third concave groove portion 111e rubs against the hole to generate shavings and the like. In some cases, it is a groove for accommodating the shavings and the like. Since the shavings and the like are housed in the third concave groove portion 111e, it is possible to prevent the waterproof property from being deteriorated due to the shavings and the like adhering to the second outer seal member 142. When the mating housing 111 is not fitted to the connector 1, the mating sealing member 131 and the second outer sealing member 142 prevent water from entering the housing.

Next, a state in which the connector 1 having the above configuration and the mating connector 101 are fitted to each other will be described.

FIG. 18 is a two-view view showing a state in which the connector and the mating connector in this embodiment are fitted. In the figure, (a) is a top view, and (b) is a cross-sectional view taken along the line MM in (a).

In the present embodiment, the connector 1 and the mating connector 101 are relatively close to each other from a state in which the housing front end 11f of the front sleeve 11 and the housing front end 111f of the mating housing 111 are separated from each other so as to be relatively close to each other. The housing front end 111f of the housing 111 relatively enters the internal cavity 11a that opens into the housing front end 11f of the front sleeve 11, and is in a state of being fitted to each other as shown in FIG.

When the connector 1 and the mating connector 101 are fitted, a portion of the mating housing 111 in front of the flange portion 111a enters and is accommodated in the internal cavity 11a of the front sleeve 11, and the mating shell 161 exposed to the front portion. The contact portion 164 of the shell 61 enters and is accommodated in the internal cavity 61a of the shell 61, the flange portion 111a of the mating housing 111 approaches or abuts on the housing front end 11f of the front sleeve 11, and the housing front end 111f of the mating housing 111 is intermediately insulated. The terminal 51 of the terminal 51 which is close to or abuts on the front end 21f of the body 21 and the contact portion 154 of the mating terminal 151 enters the internal cavity 21a which opens to the front end 21f of the intermediate insulator 21 and is housed in the internal cavity 21a. It enters between the pair of contact arm portions 54 and is sandwiched from both sides.

Further, the vicinity of the housing front end 111f of the mating housing 111 and the vicinity of the front end 21f of the intermediate insulator 21 have substantially the same diameter, and are arranged side by side in the insertion / removal direction (X-axis direction) of the connector 1 and the mating connector 101. It becomes. Similarly, the contact portion 164 of the mating shell 161 is also arranged side by side with the intermediate insulator 21 and the terminal 51 in the insertion / removal direction. Further, the member of the mating connector 101 that enters behind the slit 63a of the shell 61 (in the negative direction of the X-axis) is only the contact portion 154 of the mating terminal 151, and the mating housing 111 and the mating shell 161 are the slits. Do not enter further behind 63a. Further, even if the connector 1 and the mating connector 101 are twisted while being fitted to each other, or the cable 91 is pulled diagonally, the portion in front of the slit 63a of the shell 61 (in the positive direction of the X-axis) is flexible. Therefore, even if the mating between the connector 1 and the mating connector 101 is released, the connector 1 or the mating connector 101 is not damaged. Therefore, the diameter of the connector 1 and the mating connector 101 can be reduced, and the connector 1 and the mating connector 101 are not easily damaged while maintaining the insertability (fitting feeling, insertion force, pulling pulling force, etc.) and contactability. You can get a connector assembly.

Further, since the tapered portion 21a1 is formed in the internal cavity 21a of the intermediate insulator 21, the tip of the mating terminal 151 can smoothly enter the internal cavity 21a. Further, since the distance between the contact arm portions 54 at the free ends of the pair of contact arm portions 54 facing each other is smaller than the outer diameter of the counterpart terminal 151, the counterpart terminal 151 enters between them. When expanded by, a repulsive force is generated as a spring, and the other terminal 151 is sandwiched from both sides. As a result, the contact between the contact arm portion 54 and the mating terminal 151 is reliably maintained, and the contact is reliably maintained. Further, a plurality of lock protrusions 64 formed in the main body portion 63 of the shell 61 engage with the recess 164b formed in the contact portion 164 of the mating shell 161. As a result, the contact between the main body 63 of the shell 61 and the contact portion 164 of the mating shell 161 is reliably maintained, and the contact is reliably maintained. Further, the first outer seal member 141 attached to the first concave groove portion 111c of the mating housing 111 is pressed against the inner peripheral surface of the inner cavity 11a of the front sleeve 11. As a result, the outer peripheral surface of the mating housing 111 and the inner peripheral surface of the inner cavity 11a of the front sleeve 11 are hermetically sealed to prevent the ingress of moisture.

Even when moisture passes through the portion sealed by the first outer seal member 141 and enters the inside, in the connector 1, the seal member 31 causes the tail portion 52 of the terminal 51. Since the periphery of the tail portion 62 of the shell 61 and the core wire 94 of the cable 91 connected to them is covered, moisture does not enter the tail portion 52 of the terminal 51, the tail portion 62 of the shell 61, and the core wire 94. It is definitely prevented. Similarly, in the mating connector 101, since the mating shell member 131 covers the space between the mating shell 161 and the mating terminal 151 and its surroundings, the tail portion 152 of the mating terminal 151 and the tail portion 162 of the mating shell 161 are covered. The ingress of moisture into is reliably prevented.

As described above, in the present embodiment, the mating connector 101 is connected to the mating housing 111 made of an insulating material, the main body portion 163 embedded in the mating housing 111, and the main body portion 163, and is connected to at least a part of the outer peripheral surface. Is connected to the mating outer conductor portion 161 including the contact portion 164 exposed from the mating housing 111, the main body portion 153 embedded in the mating housing 111, and the main body portion 153, and at least the tip thereof is from the housing front end 111f of the mating housing 111. A mating center conductor portion 151 projecting forward, and a main body portion 163 of the mating outer conductor portion 161 include a curved portion 163a having a substantially crank-shaped side surface shape.

As a result, it is possible to obtain a highly reliable mating connector 101 that is compact but has high waterproofness and insertability.

Further, a mating seal member 131 made of an insulating material is further provided, the mating outer conductor portion 161 includes a tail portion 162 extending rearward from the main body portion 163, and the mating center conductor portion 151 is provided from the main body portion 153. The mating seal member 131 includes a tail portion 152 extending rearward, and the mating sealing member 131 includes a connecting portion between the main body portion 163 and the tail portion 162 of the mating outer conductor portion 161 and the main body of the mating central conductor portion 151 in the mating housing 111. It is integrally molded so as to surround the periphery of the connecting portion between the portion 153 and the tail portion 152. Inclined portions 162a that migrate to the narrow main body portion 163 are formed on both sides in the width direction at the front end of the tail portion 162 as a connecting portion of the mating outer conductor portion 161, and the front end of the tail portion 152 as a connecting portion of the mating center conductor portion 151. An inclined portion 152a that shifts to the narrow main body portion 153 is formed on both sides in the width direction, and a sealing member is integrally formed so as to surround the periphery of the inclined portion. The main body portion 163 of the mating outer conductor portion 161 and the main body portion 153 of the mating center conductor portion 151 are formed in a plate shape and arranged in parallel with each other, and the thickness of the main body portion 163 of the mating outer conductor portion 161 is the mating center conductor portion. It is thinner than the main body of 151.
