  By the way, the molding die which molds the peripheral part of the terminal receiving port cannot be opened in the front-rear direction which is the direction in which the terminal insertion hole extends, and the mold is opened in the direction intersecting with the direction in which the terminal insertion hole extends. In the case of using a mold, it is difficult to construct a guide structure at the peripheral edge of the terminal insertion opening.

The present invention was completed based on the circumstances as described above, be a molding die to mold opening in a direction intersecting the direction of extension of the terminal insertion holes long et al, guiding the peripheral edge of the terminal insertion opening The object is to shape the structure and allow the terminal to be inserted into the terminal insertion hole.

As means for achieving the above object, the present invention provides a connector housing made of synthetic resin having a terminal insertion hole for inserting a terminal from the rear, and a terminal insertion port on the side where the terminal of the terminal insertion hole is inserted. An elastic portion that is formed in a peripheral portion and elastically deforms in the insertion direction of the terminal to draw the terminal into the terminal insertion hole, and in the connector housing forward of the insertion direction with respect to the peripheral portion of the terminal insertion port , the elastic part is characterized by the open formed Tei Rutokoro to an outer surface of the connector housing in the direction in which the bending space for the elastic deformation intersects the inserting direction of the terminal.
According to the connector having such a configuration, when the terminal is inserted into the terminal insertion hole in a state in which the distal end portion of the terminal is shifted from the axial center of the terminal insertion hole, The portion is elastically deformed in the terminal insertion direction, and the terminal can be inserted into the terminal insertion hole.
In addition, the molding die that molds the periphery of the terminal insertion port cannot be opened in the front-rear direction, which is the direction in which the terminal insertion hole extends, and the molding die that opens in the direction intersecting with the direction in which the terminal insertion hole extends In the case of using, by opening the mold in the front-rear direction, it becomes impossible to provide a guide structure at the peripheral portion of the terminal insertion opening. However, according to the above configuration, since the elastic portion having a bending space in the front is formed at the peripheral edge portion of the terminal insertion port, the terminal can be further easily guided into the terminal insertion hole.
Moreover, in order to form a bending space in front of the elastic part, if a bending space opened forward is formed, the terminal insertion hole needs to be enlarged in the radial direction, and the terminal inserted into the terminal insertion hole is inserted into the terminal. There is a risk of rattling in the hole. However, according to the above configuration, the bending space forming pin formed in the molding die that opens in the direction intersecting with the extending direction of the terminal insertion hole is pulled out in the direction intersecting with the extending direction of the terminal insertion hole. A bending space can be formed in front of the elastic portion. Thereby, a bending space can be formed without enlarging the terminal insertion hole in the radial direction.

The following configuration is preferable as an embodiment of the present invention.

According to such a configuration, by making a cut in the elastic portion, the elastic portion can be more easily elastically deformed in the terminal insertion direction.

The elastic portion may be formed with a die-cut groove that is recessed forward in the insertion direction of the terminal and opens to the outer surface of the connector housing in the same direction as the opening direction of the flex space.
According to such a configuration, since the punching groove that is recessed forward in the insertion direction of the terminal is formed in the elastic portion, the terminal can be further guided into the terminal insertion hole and can be easily inserted. Moreover, since the die-cutting groove is opened in the same direction as the opening direction of the bending space, the die-cutting groove can be easily formed when the bending space is formed.

Further, the present invention is a connector housing made of synthetic resin having a terminal insertion hole for inserting a terminal from the rear, and a terminal insertion hole on the side where the terminal of the terminal insertion hole is inserted, and the terminal A connector provided with an elastic portion that is elastically deformable in a bending space formed to open to the outer surface of the connector housing in a direction intersecting the insertion direction of the terminal in a direction crossing the insertion direction of the terminal in front of the peripheral portion of the insertion port. The bending space is formed by extracting the bending space forming pin formed in the molding die for forming the peripheral edge of the terminal insertion port in the opening direction of the bending space. Have.
According to such a manufacturing method, since the flex space opens to the outer surface of the connector housing in a direction intersecting with the direction in which the terminal insertion hole extends, the flex space forming pin provided in the molding die is inserted in the flex space opening direction. By pulling out, the bending space of the elastic portion can be formed in front of the peripheral edge portion of the terminal insertion port. That is, it is possible to elastically deform located at molding die to mold opening in a direction crossing the direction length, et al, an elastic portion at the front an insertion direction of the terminal of extension of the terminal insertion hole. As a result, the terminal elastically deforms the elastic part forward, so that the tip of the terminal can be guided and inserted into the terminal insertion hole.

According to the present invention, be a molding die to mold opening in a direction intersecting the direction of extension of the terminal insertion holes long et al, shaping the guiding structure to the peripheral portion of the terminal insertion openings, is Sasoikon terminal into the terminal insertion hole Can be inserted.

Yes.

The optical connector 10 of the present embodiment has the above configuration, and an example of a method for forming the housing body 30 will be described.
As shown in FIGS. 15 and 16, the housing body 30 is molded by a molding die 60 that includes an upper mold 61 and a lower mold 62 that open up and down, and a slide mold 63 that opens forward.

  First, in a state where the molding die 60 is closed, a molten resin is injected into the molding die 60 to mold the housing body 30 as shown in FIG.

  When the resin injected into the molding die 60 is cooled and hardened, the respective molds 61, 62, 63 are opened and the housing body 30 is taken out from the molding die 60 as shown in FIG. Thus, the housing body 30 is completed.

  By the way, when forming the cable holding part 36 etc. in the back of the peripheral part of the terminal insertion port 34A like this embodiment, it is the up-and-down direction which is the direction which cross | intersects the front-back direction which is the direction where the terminal insertion hole 34 is extended. The housing body 30 is molded using a molding die 60 that opens in the direction. For this reason, unlike the prior art, it is not possible to form a guide structure for opening the molding die in the front-rear direction to guide the ferrule 20 to the peripheral edge of the terminal insertion port 34A. However, in order to form a guide structure at the peripheral edge of the terminal insertion opening 34A, a dedicated mold that slides in the front-rear direction is provided between the terminal insertion opening 34A and the cable holding section 36, and the dedicated mold is slid rearward. Then, if the lead-in structure is formed at the peripheral edge of the terminal insertion port by pulling the dedicated die upward, the manufacturing cost of the optical connector 10 increases.

  However, according to this embodiment, as shown in FIGS. 15 and 16, the upper mold 61 of the molding die 60 for molding the optical connector 10 has a vertical direction that is a direction intersecting with the extending direction of the terminal insertion hole 34. A bending space forming pin 64 extending in the direction of the shape is formed, and when the upper die 61 and the lower die 62 are opened, the bending space forming pin 64 is pulled upward through the die extraction passage 43 to thereby form the terminal insertion port 34A. The bending space 41 can be formed in front of the peripheral edge portion. That is, the elastic portion 42 that can be elastically deformed toward the bending space 41 can be formed on the peripheral portion of the terminal insertion port 34 </ b> A without providing a dedicated mold for the guiding structure for forming the guiding structure in the molding die 60. It can suppress that a manufacturing cost becomes high.

  Further, the upper die 61 extends in a vertical direction, which is the same direction as the bending space forming pin 64, at a position slightly rearward from the bending space forming pin 64, and a lower end portion projects in a tapered manner toward the front. A lead-in molding part 61A is formed. When the upper mold 61 and the lower mold 62 are opened, the guide molding portion 61A is pulled into the peripheral portion of the terminal insertion port 34A by pulling the guide molding portion 61A upward in the same manner as the bending space molding pin 64. The surface 39 and the die-cutting groove 40 can be easily formed. That is, the die-cutting groove 40 for making it easier to draw the ferrule 20 into the terminal insertion hole 34 can be easily formed on the rear surface of the elastic portion 42.

Next, the procedure for assembling the optical connector 10 will be briefly described, and the operational effects when the ferrule 20 is assembled to the housing body 30 will be described.
First, the ferrule 20 connected to the housing body 30 and the end of the optical fiber core W2 is prepared, and the sleeve 23 is attached to the capillary 21 of the ferrule 20.

  Next, the sleeve 23 is inserted into the terminal insertion hole 34 with the axis of the sleeve 23 aligned with the axis of the terminal insertion hole 34 of the housing body 30, and the ferrule 20 is disposed at the front end of the flange housing portion 33. Here, when the sleeve 23 is inserted into the terminal insertion hole 34 in a state where the axis of the sleeve 23 is slightly shifted to the upper half of the axis of the terminal insertion hole 34, the elastic portion 42 becomes the sleeve as shown in FIG. 14. The tip of the sleeve 23 is pressed and elastically deformed toward the bending space 41, and the tip of the sleeve 23 is drawn into the terminal insertion hole 34 and inserted. Thereby, the efficiency of the assembly | attachment operation | work of the ferrule 20 with respect to the housing main body 30 can be improved.

  Then, after the two ferrules 20 to which the sleeves 23 are attached are assembled to the capillary housing portion 32, the caulking ring R of the optical cable W is housed in the housing groove 37 of the flange housing portion 33, and the cover 50 is attached to the flange housing portion 33. By assembling from above, the optical cable W is held and fixed by the housing body 30 and the cover 50, and the optical connector 10 is completed.

As described above, according to this embodiment, when the upper mold 61 and the lower mold 62 of the molding die 60 are opened, the bending space molding pin 64 of the upper mold 61 is pulled upward, so that the terminal insertion port 34A. It is possible to easily form the bending space 41 in the peripheral edge. In other words, it is a molding die 60 for mold opening in the vertical direction intersecting the extending direction of the terminal insertion hole 34 long et al, the elastically deformable elastic portion 42 toward the space 41 bending the peripheral edge of the terminal insertion opening 34A Can be molded. Accordingly, the sleeve 23 attached to the ferrule 20 can be easily guided into the terminal insertion hole 34 by the elastic portion 42, and compared to an optical connector in which a guide structure is not provided at the peripheral portion of the terminal insertion port. The efficiency of the assembly work can be improved.
Further, according to the present embodiment, since the cut 44 is formed in the elastic portion 42, the elastic portion 42 which is the peripheral portion of the terminal insertion port 34A and the peripheral portion of the cut 44 is elastically deformed further forward. Therefore, the distal end portion of the sleeve 23 can be easily guided by the terminal insertion hole 34.
Further, according to the present embodiment, since the rear surface of the elastic portion 42 is tapered toward the axial center of the terminal insertion hole 34 as the front surface of the die cutting groove 40, the ferrule 20 can be more easily guided into the terminal insertion hole 34. can do.

  Further, when the guide surface 39 is formed in the lower half of the peripheral edge portion of the terminal insertion port 34A by pulling out the guide forming portion 61A upward as in the present embodiment, the die cutting groove is formed above the guide surface 39. 40 needs to be formed, and a guiding structure similar to the guiding surface 39 cannot be provided in the upper half of the peripheral edge of the terminal insertion port 34A. However, according to the present embodiment, since the elastic portion 42 that is a guide structure can be provided in the upper half of the peripheral portion of the terminal insertion port 34A, in forming the guide structure in the peripheral portion of the terminal insertion port 34A, It is very effective.
