Tail portion 52 has the linking part 52c for being integrally connected to body part 53.Linking part 52c is for will be after body part 53 The component that the front end of end and tail portion 52 links, and (be Y-axis side in example shown in the figure being orthogonal to direction in the front-back direction To) on extend, and be used as block square tube shape body part 53 rear end cover.In example shown in the figure, linking part 52c is bent from the rear end of side wall for forming joint protrusion 53a on the body part 53 of square tube shape with general right angle, and with the side Extend on the direction (Y-axis negative direction) of the opposite side wall of wall, then, is bent after crossing side wall toward each other, with general right angle And then it is integrally connected to the front end of tail portion 52 extended in the longitudinal direction.In this manner, because of the ontology of square tube shape The rear end connecting portion 52c in portion 53 is blocked, and is constituted the insulating materials of cap body 22 so being reliably prevented from, is constituted seal member 31 elastomer enters the inside of square tube from rear end and enters between contact arm portion 54.

In addition, the first connection orthogonal when being observed from the length direction (X-direction, i.e. front-rear direction) of connector 1 Plate 52a and the second connecting plate 52b are arranged near the rear end of tail portion 52.Second connecting plate 52b is relative to the first connecting plate 52a It is formed at the mode that right angle is bent.As shown in Figure 4 C, with the coating member on the inside of the removal of the end of the first conducting wire 93a of cable 91 The the first core wire 94a exposed in the state of 95 is orthogonal two in the observation along the longitudinal direction on its periphery Position abuts respectively or close to the first connecting plate 52a and the second connecting plate 52b, and is connected to by the connection means of welding etc. First connecting plate 52a and the second connecting plate 52b.Therefore, even if range the first core wire 94a Chong Die with tail portion 52 is in front-rear direction It is upper short, but because two positions of the first core wire 94a on the periphery of the first core wire 94a are connected to the first connecting plate 52a and the Two connecting plate 52b, so the first core wire 94a and tail portion 52 are reliably connected to each other and are reliably connected each other.

Internal cavity 21a of the terminal 51 from rear indentation intermediate insulator 21.Then, the body part 53 of square tube shape enters In the square hole portion 21a3 formed on the part adjacent with rear end 21r in internal cavity 21a, and a pair of of contact arm portion 54 into Enter into the circular hole portion 21a2 positioned at the front of square hole portion 21a3.At this point, the internal diameter of circular hole portion 21a2 is less than the outer of body part 53 Diameter, and the part near the front end of tail portion 52 in linking part 52c abuts the rear surface of positioning protrusion 21c, therefore, ontology Portion 53 will not enter circular hole portion 21a2, and complete the positioning relative to intermediate insulator 21 in the longitudinal direction of terminal 51.In addition, Because the body part 53 of square tube shape is contained in square hole portion 21a3, terminal 51 is completed in a circumferential direction relative to intermediate exhausted The positioning of edge body 21.Because the joint protrusion 53a of body part 53 bites the inner wall of square hole portion 21a3, terminal 51 is in front and back Opposite intermediate insulator 21 will not be displaced upwards.In addition, as shown in Figure 4 A and 4 B shown in FIG., contact arm portion 54 stops at circular hole portion 21a2 It is interior and do not enter tapered portion 21a1.

In addition, terminal 51 be pressed into intermediate insulator 21 internal cavity 21a and the intermediate insulator 21 has been pressed into shell In the state of in 61 internal cavity 61a, as shown in Figure 4 A, the tail portion 62 of the tail portion 52 of terminal 51 and shell 61 is opposite to each other backward Extend.Specifically, the barrel of the cylindric body part 63 of the tail portion 52 of terminal 51 and shell 61 is substantially flush, in circumferencial direction Above it is located at the opposite sides of the tail portion 62 of shell 61 and extends back.That is, the tail portion 52 of terminal 51 and the tail portion 62 of shell 61 are constituted A part of cylinder wall surface with the diameter roughly the same with the cylinder wall surface of body part 63 of shell 61.In addition, in front and back On direction, the position of the rear end of the tail portion 52 of terminal 51 and the position of rear end of tail portion 62 of shell 61 are identical, and terminal 51 The position of first connecting plate 52a and the second connecting plate 52b are also with the first connecting plate 62a's of shell 61 and the second connecting plate 62b Position is identical.As shown in Figure 4 C, the first connecting plate 62a of the first connecting plate 52a of terminal 51 and shell 61 toward each other, and is held The second connecting plate 62b of the second connecting plate 52b and shell 61 of son 51 are substantially flush each other.

In this way, the internal cavity 61a and terminal 51 in the indentation shell 61 of intermediate insulator 21 are pressed into intermediate insulator 21 After internal cavity 21a, the cap body 22 as shown in Fig. 9 A~Fig. 9 C and Figure 10 A~Figure 10 C by cladding forming it is integrally formed The rear side of intermediate insulator 21 and terminal 51.For convenience's sake, in Fig. 9 A~Fig. 9 C and Figure 10 A~Figure 10 C, cap body 22 is single It solely shows, but cap body 22 is by cladding forming (insert part forming) and intermediate insulator 21, terminal 51 and shell 61 1 The component of body chemical conversion shape, wherein cladding forming, which refers to, is being mounted in forming for intermediate insulator 21, terminal 51 and shell 61 The dielectric material of such as synthetic resin is filled into mold in the state of in mold, therefore, cap body 22 is actually not with tool It is existing just like the monomer of shape shown in Fig. 9 A~Fig. 9 C and Figure 10 A~Figure 10 C.

As a result, the insulating materials for constituting cap body 22 enters the shell 61 for accommodating intermediate insulator 21 and terminal 51 in the inner The rear end 63r of body part 63 and the outer peripheral surface of body part 63 on rear end 63r nearby in part, shell 61 and centre it is exhausted Gap between edge body 21 and terminal 51, to be closed.In addition, constituting the insulating materials of cap body 22 via intermediate insulator 21 Recess portion 21b, into the opening 63b formed on the body part 63 of shell 61, thus and fill recess portion 21b and opening 63b, with shape At cap body 22, thus cap body 22 reliably attaches to shell 61 and intermediate insulator 21.In addition, because connecting portion 52c is blocked Rear end further blocked by cap body 22 from rear, therefore be contained in the square hole portion of the internal cavity 21a of intermediate insulator 21 The body part 53 of terminal 51 in 21a3 will not be extracted from square hole portion 21a3.

Specifically, the cylindrical portion 22c of cap body 22 enters from the rear end side 63r of the body part 63 of shell 61 and is located at body part 63 Internal cavity 61a in intermediate insulator 21 recess portion 21b, the outside portion 22h on the outside of radial direction is more depended on than cylindrical portion 22c Enter between the notch section 65 of shell 61 and the positioning protrusion 21c of intermediate insulator 21 and cover positioning protrusion 21c, and from circle The appearance of canister portion 22c enters the opening 63b of shell 61 towards protruding portion 22b outstanding on the outside of radial direction.In addition, intermediate insulation Part near the rear end of body 21 enters in the front cavity 22d formed in cylindrical portion 22c, after the body part 53 of terminal 51 Part near end enters the rear cavity 22e than front cavity 22d rearward, the portion near the front end of the tail portion 62 of shell 61 Divide the notch section 22g into periphery, and positioning protrusion 21c enters in the outboard chambers 22i in the 22h of outside portion.

The recess portion 21b of intermediate insulator 21 does not extend on the entire perimeter of intermediate insulator 21, and such as Fig. 6 A~Fig. 6 D It is shown, rear side protrusion 21e is formed in a part.Therefore, as shown in Figure 10 A~Figure 10 C, on the cylindrical portion 22c of cap body 22 It is formed with recess portion 22m corresponding with rear side protrusion 21e, as shown in Fig. 9 A~Fig. 9 C and Figure 10 A~Figure 10 C, in the circle of cap body 22 It is formed on canister portion 22c into the small―gap suture between the inner peripheral surface of the body part 63 of the outer peripheral surface and shell 61 of intermediate insulator 21 In thinner wall section 22k.Although due to gap variation and thinner wall section 22k may not be formed, even if thinner wall section 22k not shape At waterproof performance is also unaffected because of cap body 22.

As previously mentioned, cap body 22 forms shape by cladding forming, even and if thus each component becomes smaller to minimize, cap Body 22, intermediate insulator 21, shell 61 and terminal 51 also can be reliably integrated.Figure 11 A, Figure 11 B are shown to be covered in front Cylinder 11 forms a part of assembly in the state of shape by cladding forming.In addition, as shown in Figure 11 B, when cap body 22 passes through packet Forming is covered when shaping, and the cast gate for being formed in the wall surface of unshowned molding die (mould) is located at the rear surface of cap body 22 Front constitutes the insulating materials of cap body 22 as filled in molding die as indicated by arrow 43 by the cast gate, and enters Each component is so that these part integrations.Aforementioned cast gate can be only a bit, can also be multiple spot.For example, cast gate 43 and cast gate 43a energy Enough it is arranged in the Z-direction two sides and toward each other of cap body 22.As a result, when using insulating materials filling molding die, The pressure for acting on the insulating materials on the component in molding die is easy homogenization, and is able to suppress the position because of these components Set the generation that product caused by deviation is discontented with (short molding).It should be noted that gate vestiges 22j remains in forming On the surface of cap body 22 afterwards.

As shown in Fig. 8 A, Fig. 8 B, the outer peripheral surface of cap body 22 is formed as the periphery with the cylindric body part 63 of shell 61 The periphery that face is substantially flush.In addition, rearwardly projecting umbrella or mushroom anchor portion 22a are formed in the rear surface of cap body 22 On, and contraction flow region 22f is formed between the rear surface of cap body 22 and anchor portion 22a.The tail portion 62 of shell 61 is after cap body 22 Boundary part between surface and periphery is prominent backward and exposes, thus at least the first connecting plate 62a and the second connecting plate 62b Positioned at the rear of anchor portion 22a.Similarly, the tail portion 52 of terminal 51 is from the boundary portion between the rear surface and periphery of cap body 22 Divide prominent backward and expose, so that at least the first connecting plate 52a and the second connecting plate 52b are located at the rear of anchor portion 22a.

The core wire 94 of cable 91 is connected to the tail portion 52 of terminal 51 and the tail portion 62 of shell 61.Here, the tail portion of terminal 51 The the first connecting plate 62a and the second connecting plate of the tail portion 62 of 52 the first connecting plate 52a and the second connecting plate 52b and shell 61 62b is located at the identical position more rearward in the anchor portion 22a than cap body 22, the first connection of terminal 51 in the longitudinal direction The first connecting portion 62a of plate 52a and shell 61 is facing with each other, and the second company of the second connecting plate 52b of terminal 51 and shell 61 Fishplate bar 62b is substantially flush each other.

Therefore, the first core wire of the cable 91 for the states in parallel arrangement exposed with being removed inside coating member 95 94a and the second core wire 94b is mounted on the second connecting plate 52b of the terminal 51 of parallel arranged and the second connecting plate 62b of shell 61 On, and as a result, as shown in Fig. 8 A, Fig. 8 B, the first core wire 94a abut or close to the tail portion of terminal 51 52 the first connecting plate 52a It is connected with the second connecting plate 52b, the second core wire 94b abutting or close to the first connecting plate 62a of the tail portion of shell 61 62 and second Plate 62b.By carrying out the connection of welding etc., two positions of the first core wire 94a being located on periphery are connected to the first company Fishplate bar 52a and the second connecting plate 52b, and two positions of the second core wire 94b being located on periphery are also connected to the first connecting plate 62a and the second connecting plate 62b.In this way, due to can be by comparing simple operation movement (such as can be using robot etc.) First core wire 94a of cable 91 and the second core wire 94b are connected to the tail portion 52 of terminal 51 and the tail portion 62 of shell 61, therefore energy Enough assembling operations simplified and rationalize connector 1, and can reduce production cost.In addition, being located at due to the first core wire 94a Two positions on periphery are connected to the first connecting plate 52a and the second connecting plate 52b and the second core wire 94b is located on periphery Two positions be connected to the first connecting plate 62a and the second connecting plate 62b, therefore, even if the first core wire 94a and the second core wire 94b The length Chong Die with tail portion 52 and tail portion 62 is short in the longitudinal direction, but because the first core wire 94a is connected to the length of tail portion 52 The summation for the length that summation and the second core wire 94b are connected to tail portion 62 becomes longer, so that connection is reliable.

In this way, after the core wire 94 of cable 91 is connected to the tail portion 52 of terminal 51 and the tail portion 62 of shell 61, sealing Part 31 integrally attaches to the rear side of formed terminal 51, shell 61 and cap body 22 by coating forming.Constitute seal member (it is the material of the flexible more high flexibility of the flexible material than front sleeve 11, cap body 22 and rear socket 12 to 31 elastomer Material), into the existing gap between shell 61, intermediate insulator 21, terminal 51 and cap body 22, thus with watertight fashion By clearance seal.In addition, tail portion 52 and the shell 61 of the terminal 51 that the rear that elastomer is seamlessly covered on cap body 22 is exposed Tail portion 62 and cable 91 in connection core wire 94 around, and with watertight fashion seal clearance.It is preferred that as schemed Shown in 4A~Fig. 4 C, seal member 31 is formed as the outer peripheral surface in the front of seal member 31 and front sleeve 11 in the longitudinal direction On rear end and the rear end near partly overlap, the rear of seal member 31 is at least covered on the anchor portion until cap body 22 Around each component in the range of 22a.In addition, seal member 31 is formed as seamlessly being covered on until in conducting wire 93 Around each component in the range of the close part with front end on the outer peripheral surface of side coating member 95.

Therefore, the anchor portion 22a of cap body 22 become the state that is embedded in seal member 31 and become seal member 31 into Enter the state around contraction flow region 22f, so that cap body 22 and seal member 31 reliably combine each other.In addition, because constituting close Seal component 31 elastomer have high flexibility and seamlessly the tail portion 52 of capped end 51 and the tail portion 62 of shell 61 and with Around the core wire 94 for the cable 91 that they are connected, so being capable of tail portion 52 to terminal 51, the tail portion 62 of shell 61 and core Line 94 carries out reliably waterproof.

After seal member 31 is integrally formed by cladding forming, seal member 31 and shell 61 are made by reheating It is closely adhered, so that further increasing waterproof performance can.

Then, the rear portion that rear socket 12 is integrally attached at front sleeve 11 by coating forming, to cover seal member 31 and cable 91 conducting wire 93 around.Rear socket 12 is the outermost for being formed together connector 1 with front sleeve 11 The component of layer, and preferably, as shown in Fig. 4 A~Fig. 4 C, rear socket 12 is formed as in the longitudinal direction from close to front sleeve The part of front end on the part of rear end on 11 outer peripheral surface to the outer peripheral surface close to the outer side covering component 92 of cable 91 It is seamlessly covered around each component in range.

It should be noted that rear socket 12 can have the recess portion 12b on the entire perimeter for being present in outer surface.Recess portion 12b Device (not shown) is hooked for the chimeric or releasing chimeric (when i.e. in plug-in connector 1) in connector 1 and docking connector 101 Tool.In addition, being formed when rear socket 12 forms shape by cladding forming in the wall surface of molding die (not shown) (casting mold) Cast gate be located at the dead astern of recess portion 12b as shown in Figure 4 A, and the insulating materials for constituting rear socket 12 passes through cast gate filling In molding die, as shown in arrow 41.

Preferably, cast gate is on the Y direction two sides of rear socket 12 and toward each other.As a result, working as with insulating materials such as When filling molding die shown in arrow 41, the pressure for acting on the insulating materials on the component in molding die is easy It homogenizes, it is discontented to be able to suppress the product generated by the deviation of component.The position of cast gate preferably adjacent to outer side covering component 92, with The weldability between the outer side covering component 92 of the insulating materials and cable 91 that constitute rear socket 12 is improved, but outside is covered It is undesirable that cover 92, which is present in immediately below cast gate, this is because outer side covering component 92 can be because of the injection of insulating materials Pressure and deform.In addition, the position of cast gate is preferably covered than recess portion 12b closer to outside when rear socket 12 has recess portion 12b Cover 92.If insulation, closer to front sleeve 11, is filled than thin recessed 12b in the position of cast gate in molding die Pressure needed for material is got higher, so that cable 91 may deformation.In view of these facts, it is preferable that cast gate is in such as Fig. 4 A institute The position shown.It should be noted that gate vestiges 12c remains on the surface of rear socket 12 of forming.

In addition, the insulating materials overflow filled in molding die and being flowed out as shown in arrow 42 from molding die. Preferably, insulating materials is since the outflow of overflow is also in the position progress toward each other of the Y direction two sides of rear socket 12. Insulating materials overflow, to constitute the weldability between the insulating materials of rear socket 12 and the outer side covering component 92 of cable 91 It gets higher, thus improves waterproof performance.Preferably, the rear end 12r for being closely located to rear socket 12 of insulating materials outflow, to improve Weldability between insulating materials and outer side covering component 92.It should be noted that overflow trace 12d remains in the rear square set of forming On the surface of cylinder 12.
