Abstract

PROBLEM TO BE SOLVED: To reduce man hours for molding and assembling by reducing the number of part items. SOLUTION: A terminal fitting 32 is inserted into a housing 10 through a terminal slot 13 and a wire 33 secured to the terminal fitting 32 is extended from the terminal slot 13. A filler 31 is injected into the injection chamber 14 of the housing 10 to prevent foreign matter from entering through the terminal slot 13 and to seal the extension passage of the wire 33. A sealing member 29 provided on the mating part 24 of the housing 10 which mates with a mating connector seals a space between the housing 10 and the mating connector. Since the sealing member 29 is molded integrally with the filler 31 in the injection chamber 14, this connector has a smaller number of part items than if the sealing member is molded as a separate component and assembled to the mating part, so that man hours for molding and assembling operations can be reduced.

The step-shaped opposing surface 27 faces the side surface. In the bottom wall 16 of the injection chamber 14, five communication holes 28 that communicate the inside of the injection chamber 14 and the space surrounding the sealing surface 25 are formed vertically. The two left and right communication holes 28 are arranged so as to correspond to the injection opening 22, and the other three communication holes 28 are arranged along the rear surface of the terminal insertion part 12. The filler 31 flows between the injection chamber 14 and the space surrounding the sealing surface 25 by passing through the communication hole 28. And this sealing surface 25
A seal member 29 integral with the filler 31 is fitted inside the injection chamber 14.

The housing 10 is set on the mold 35 in such a manner that the lower surface of the bottom wall 16 of the injection chamber 14 (the ceiling surface of the space surrounding the fitting portion 24) is brought into contact with the upper end surface thereof. When set in the mold 35, a cylindrical molding space 39 is formed between the molding inner peripheral surface 37 and the sealing surface 25 and communicates with the injection chamber 14 through the two left and right communication holes 28. At the same time, the housing 10 comes into contact with the mold 35 at two positions on the upper and lower ends of the molding space 39 in the direction of setting the mold 10 in the mold 35.

In the setting direction to the mold 35, 2
As shown in FIG. 16, a small ridge 30 protruding along the outer peripheral edge of the step-like opposed surface 27 at the lower end of the seal surface 25, which is one of the contact positions, is provided over the entire circumference. It is formed continuously. The ridge 30 has a wedge-shaped cross section with a sharpened lower end, and its outer surface is flush with the sealing surface 25. In addition, the step-like opposing surface 27 of the ridge 30

The ridges 30 are plastically deformed so as to be crushed when the housing 10 is set on the mold 35, thereby forming the step-shaped opposing surface 27 of the housing 10 and the step-shaped receiving surface 3 of the mold 35.
8 (a gap in the setting direction of the housing 10 in the mold 35) is filled over the entire circumference.

[Cover 40] The cover 40 is assembled so as to cover the terminal insertion opening 13 with respect to the upper surface of the housing 10, and the lower surface of the peripheral portion is brought into contact with the upper end surface of the peripheral wall of the injection chamber 14. The main body 41 has a rectangular plate shape as a whole, and a peripheral wall 42 extending downward from the lower surface of the main body 41. Front wall 42F of peripheral wall 42
Has a thickness that is fitted almost tightly into a small gap between the front wall 15F of the injection chamber 14 and the front surface of the terminal insertion portion 12. The first half of the left and right side walls 42S of the peripheral wall 42 has a thickness that fits into a small gap between the side wall 15S of the injection chamber 14 and the side surface of the terminal insertion portion 12, and the terminal insertion of the side wall 42S is performed. The rear half portion that deviates from the part 12 is almost in close contact with the inner surface of the side wall 15S of the injection chamber 14.

A rear wall 42R of the peripheral wall 42 (a holding projection for holding the electric wire 33, which is a constituent element of the present invention, in a state of being immersed in the filler 31) is provided at a position slightly forward of the rear end of the cover 40. It is connected to the side wall 42S. This back wall 4
An arc-shaped pressing surface 43 corresponding to the arc-shaped receiving surface 19 of the receiving portion 18 in the injection chamber 14 is formed on the lower end surface of the 2R. The heights of the lower ends of the front wall 42F, the side wall 42S, and the rear wall 42R are determined in a state where the cover 40 is assembled to the housing 10 (the lower surface of the peripheral portion of the main body 41 of the cover 40 contacts the upper end surface of the peripheral wall 15 of the injection chamber 14). Contact state)
The height is set to be lower than a predetermined liquid level of the filler 31 injected into the injection chamber 14. Therefore, in the assembled state, the lower end of the peripheral wall 42 is immersed in the filler 31 in the injection chamber 14 over the entire circumference.

From the rear end of the side wall 42S (continuous portion with the rear wall 42R), there is formed an extension wall 44 which is flush with the side wall 42S and extends rearward. This extension wall 44
Is substantially in close contact with the inner surface of the side wall 15S of the injection chamber 14 similarly to the side wall 42S, and the height of the lower end is the same as the side wall 42S, that is, the filler 31 of the injection chamber 14
It is set to the height to be immersed in. Also, cover 4
An arc-shaped pressing surface 45 corresponding to the arc-shaped receiving surface 20 of the rear wall 15 </ b> R of the injection chamber 14 is formed between the rear ends of the extending walls 44 on the lower surface of the injection chamber 14. Further, the outer edge of the cover 40 extends downward in a plate shape and has a lock hole 47.
Is formed, and in a state where the cover 40 is assembled to the housing 10, the lock hole 47 is engaged with the lock projection 23 of the housing 10 so that the cover 40 is locked in the assembled state. Has become.

[Operation of Embodiment] When assembling the connector F, first, the terminal fitting 32 is inserted into the cavity 11 and the housing 10 is opened so that the terminal insertion port 13 and the injection chamber 14 are opened upward. Determine your posture. In this state, the electric wire 33 extending from the terminal insertion port 13 is routed rearward in the injection chamber 14 along the partition wall 17 and the arc-shaped receiving surface 19 of the receiving portion 18 and the arc-shaped rear wall 15R. The cover 40 is placed on the receiving surface 20 and the cover 40 is
Is assembled to the housing 10. When the cover 40 is assembled, the front wall 42F of the peripheral wall 42 of the cover 40,
The side wall 42S and the extension wall 44 are fitted along the inner circumference of the peripheral wall 15 of the injection chamber 14, and the arc-shaped pressing surface 43 of the rear wall 42R of the cover 40 pushes down the electric wire 33 and sandwiches the electric wire 33 with the arc-shaped receiving surface 19. At the same time, the arc-shaped pressing surface 45 between the extension walls 44
Presses the electric wire 33 between the electric wire 33 and the arc-shaped receiving surface 20 (see FIGS. 9 and 13).

Next, the housing 10 is set in the mold 35. At this time, the ridge 30 formed on the outer peripheral edge of the step-shaped opposing surface 27 of the housing 10 abuts against the step-shaped receiving surface 38 of the mold 35 and is plastically deformed so as to be crushed. If the vertical dimension is within the range of the tolerance, the step-shaped opposing surface 27 and the step-shaped receiving surface 38
Is closed by the ridge 30. On the other hand, the upper end surface of the mold 35 and the lower surface of the bottom wall 16 are in contact with each other so as to closely contact each other without leaving a gap. Thus, a molding space 39 for the seal member 29 is formed between the seal surface 25 and the mold 35.

After setting in the mold 35, for example, a nozzle (not shown) is inserted into the injection opening 22 on the right side to insert the filler 3.
1 is injected into the injection chamber 14. As the filler 31, an elastic synthetic resin material such as urethane is used. The injected filler 31 is stored mainly in the right portion of the injection chamber 14, flows into the molding space 39 through the right and rear communication holes 28, and flows from the right region thereof. It goes around to the left area. Then, when the filling material 31 is filled in the molding space 39 without any gap, the filling material 31 goes up into the injection chamber 14 through the communication hole 28 on the left side, and in the left region of the injection chamber 14 It will be stored.

During this time, if the injection opening 22 on the left side is visually observed, the injection state of the filler 31 in the injection chamber 14 can be understood. When the liquid level of the filler 31 rises into the filling chamber 14 and reaches the same height as the opening surface of the left filling opening 22, the filling material 31 is injected from the right filling opening 22. To stop. Here, the height of the opening surface of the injection opening 22 is set to the same height as the predetermined liquid level of the filler 31 to be injected in the injection chamber 14 (see FIG. 14). There is no possibility that the liquid level of the agent 31 will rise above the predetermined height. Even if the injection amount is large, the surplus overflows from the injection opening 22 on the left, so that the liquid level of the filler 31 is maintained at a predetermined height. When the filler 31 is cured, the assembly of the connector F is completed.

When the filling of the filler 31 is completed, as shown in FIG.
F, the side wall 42S and the rear wall 42R) are immersed in the filler 31 in the injection chamber 14 over the entire lower end thereof, and the terminal insertion port 13 is connected to the main body 41, the peripheral wall 42, and the filler of the cover 40. It is in a sealed state in the space surrounded by the agent 31. This prevents foreign matter from entering the terminal insertion port 13 from the outside. In addition, the electric wire 33 extending from the terminal insertion port 13 is filled with the filler 3 in a space surrounded by the cover 40.
1 and cover 40 while immersed in filler 31.
Is drawn out of the connector F through a path that passes under the rear wall 42R and rises above the liquid level of the filler 31 outside the cover 40. Has been blocked.

When the mating connector M and the mating portion 24 are fitted, the inner periphery of the hood portion of the mating connector M is in close contact with the outer surface of the seal member 29 to seal between the mating connector M and the sealing surface 25. The member 29 is pressed (see FIG. 12). This prevents foreign matter from entering and infiltrating the fitting peripheral surface of the mating connector M and the connector F of the present embodiment. [Effects of Embodiment] (1) Since the seal member 29 for sealing between the mating connector M and the fitting portion 24 is formed integrally with the filler 31 in the injection chamber 14, the seal member is a separate component. The number of parts and the number of assembling steps are reduced as compared with the case of molding as.

(2) The housing 10 and the mold 35 abut at two locations at the upper and lower ends of the molding space 39. One of the abutting locations is a stepped receiving surface 38 and a stepped opposing surface. 27 is closed by the deformation of the ridges 30, so that the molding tolerance of the housing 10 is absorbed. Accordingly, burrs do not occur on the inner peripheral side or the outer peripheral side at both the upper and lower ends of the seal member 29. (3) Since the filler 31 is used as a means for preventing foreign matter intrusion and water intrusion, and a rubber stopper is not required, a troublesome operation of penetrating the electric wire 33 through the rubber stopper is unnecessary, and the assembling workability is excellent. .

(4) Since the liquid level of the filler 31 in the injection chamber 14 is lower than the opening surface of the terminal insertion port 13, the filler 31 may enter the cavity 11 from the terminal insertion port 13. Is prevented. (5) Since the height of the injection opening 22 is set to be lower than the opening surface of the terminal insertion port 13, even if the injection amount of the filler 31 exceeds an appropriate amount, the liquid level of the filler 31 does not increase. Before reaching the injection opening 22, and the filler 31 overflows from the injection opening 22. Therefore, the filler 31
Does not enter the cavity 11 from the terminal insertion opening 13.

(6) Two injection openings 22 are provided, one of which is used for injection of the filler 31, and the other is used for exhaust. Thus, even when the injection opening 22 on the injection side is closed by a nozzle or the like, the air in the injection chamber 14 and the molding space 39 is discharged to fill the filler 31.
Can be smoothly performed. Further, the injection state of the filler 31 can be visually observed from the injection opening 22 on the exhaust side, so that the injection amount of the filler 31 can be easily grasped and adjusted.

(7) Injection openings 2 on both the injection side and the exhaust side
2 is set to the same height as the predetermined liquid level of the filler 31, so that if the injection amount is too large, the excess filler 31 overflows from the injection opening 22. The liquid level of the filler 31 in the injection chamber 14 is maintained at a predetermined height. Further, it is easy to visually confirm the injection amount of the filler 31 from the exhaust side. (8) The electric wire 33 is filled with the filler 31 in the peripheral wall 15 of the injection chamber 14.
If it is drawn out through a position below the liquid level of the liquid, it is necessary to take measures to prevent the leakage of the filler 31 at the penetrating portion.
Projecting from the liquid surface of the filler 31 and surrounding the wall 15 of the injection chamber 14
, So that the means for preventing leakage of the filler 31 as described above is not required.

(9) The electric wire 33 projecting from the liquid surface of the filler 31 behind the rear wall 42R of the cover 40 is formed between the arc receiving surface 20 of the rear wall 15R of the injection chamber 14 and the arc pressing surface 45 of the cover 40. Since the floating is restricted by being sandwiched between the fillers, the filler 31 is not damaged or deformed by the displacement of the electric wire 33. (10) When the cover 40 is assembled to the housing 10, the rear wall 42 </ b> R of the cover 40 is pushed down to a position where the electric wire 33 is immersed in the filler 31 and is held at the same position. Therefore, the workability is superior to the case where the operation of holding the electric wire 33 at the immersion position is performed separately from the assembly of the cover 40.

(11) The electric wire 33 held at the immersion position by the rear wall 42R of the cover 40 is inserted into the injection chamber 1 through the terminal insertion port 13.
4 and is bent in an S-shape between the rear wall 15R and the terminal insertion port 13 and the lower edge of the rear wall 42R of the cover 40, and the terminal 40 is in a tension state. Therefore,
Even if a pulling force acts on the wire 33 rearward, the axial displacement of the wire 33 is prevented by friction between the leading edge of the rear edge of the cover 40 and the edge of the terminal insertion port 13, and the tensile force is reduced. It is not necessary to reach the terminal fitting 32 inside.
