The present invention relates, for example, to a connector structure with a housing and a housing.

Conventionally, the connector provided with the retainer is used. Such a connector includes, for example, a terminal accommodating chamber formed in a housing, a passage communicating with the terminal accommodating chamber and the outside, an upper opening penetrating through the terminal accommodating chamber, a plate-shaped retainer, and the retainer to be opened and closed in the opening. It has a hinge to support and a rotation support point wall provided in the edge part of an opening part and contacting the retainer inserted in the said terminal accommodation chamber (for example, refer Unexamined-Japanese-Patent No. 9-147954).

According to this connector, a terminal is inserted into the terminal accommodation chamber via a passage to close the plate-shaped retainer. Then, the intermediate portion of the retainer contacts the rotation support point wall, the retainer rotates using the rotation support point wall as the support point, and the tip of the retainer is coupled to the terminal.

However, in the above-described configuration, a part of the retainer protrudes from the housing in the closed state, which makes handling difficult.

Accordingly, an object of the present invention is to provide a connector structure having a housing and a housing in which the retainer does not protrude outward in the state where the retainer is closed in view of the above circumstances.

In order to achieve the above object, the present invention adopts the following configuration.

2 is a perspective view of the connector housing 10. 3 is a side view of the connector housing 10. 4 is a front view of the connector housing 10.

As shown in Figs. 2 to 4, the connector housing 10 includes a rectangular cylindrical housing main body 12 and a slightly thin cylindrical sleeve 14 connected to one end side of the housing main body 12. It is configured to include. This connector housing 10 has a connector opening 13 on the housing main body 12 side and a wire opening 15 on the sleeve 14 side. Inside the connector housing 10, a plug contact assembly 70 inserted from the wire opening 15 and a receptacle contact assembly 80 inserted from the connector opening 13 are connected.

Retainers 16 extending in the out-of-plane direction are formed on the surfaces of the housing body 12 that face each other. That is, these retainers 16 extend in the left and right directions in Fig. 2, and both have the same shape. Therefore, below, the retainer 16 of the left side is demonstrated, but the same holds for the retainer 16 of the right side.

The retainer 16 is integrally provided with the housing main body 12, has flexibility, and opens and closes the retainer opening 26 described later. The retainer 16 is an inverted c shape having two substantially parallel frames and a connecting frame connecting the leading ends of these frames. The projection 18 is provided in the connecting frame of the tip of the retainer 16. In addition, the length from the base end of the retainer 16 to the projection 18 of the retainer 16 is equal to the length from the base end of the retainer 16 to the retainer opening 26.

The projection part 18 is formed with the substantially rectangular board | plate material with comparatively thin plate | board thickness, and extends across the frame of the retainer 16. As shown in FIG. This protrusion 18 is inserted into a retainer opening 26 which will be described later. A lance 20 is provided on the left side in Fig. 2 of the distal end of the protrusion 18. When the retainer 16 is closed and the retainer opening 26 is closed, the lance 20 engages with the opening inner corner portion 27 (see FIG. 5), which will be described later.

5 is a cross-sectional view taken along line AA ′ of FIG. 3, and FIG. 6 is a cross-sectional view taken along line BB ′ of FIG. 3. 7 is a partially enlarged perspective view of the housing body 12.

The predetermined position at the base end side of the retainer 16 is a bend portion 37. The cutout part 38 is formed in the surface on the opposite side to the protrusion part 18 side among this bend part 37. As shown in FIG.

The housing main body 12 is formed with a recess 24 as a retainer housing portion in which the retainer 16 is stored. This recessed part 24 is formed in the shape of the door extending in the axial direction of the housing main body 12 (refer FIG. 2).

The slit 34 is formed between the junction part of the retainer 16 with respect to the housing main body 12, and the bottom face 35 of the recessed part 24. As shown in FIG. The end edge of the slit 34 side of the bottom surface 35 is the contact part 33 chamfered so that it may become predetermined curvature.

The recessed part 24 is formed with the retainer opening 26 which accommodates the retainer 16 of a frame. The retainer opening 26 is enlarged and opened toward the outside of the housing main body 12 so that the protrusions 18 of the retainer 16 can be smoothly performed. The inner end edge of the retainer opening 26 is the opening inner edge 27.

In addition, the part enclosed by the recessed part 24 of the housing main body 12 becomes the ridge part 22 of substantially rectangular shape. The raised portion 22 protrudes outward from the concave portion 24, but has a shape along the outer surface of the housing main body 12 as shown in FIG. The ridge 22 is formed with an inclined portion descending toward the retainer opening 26 as it is directed toward the connector opening 13 side. According to this inclination part, when the retainer 16 is inserted into the retainer opening 26, it does not catch and can be inserted smoothly.

Here, the operation of the retainer 16 will be described.

FIG. 8 is a partially enlarged view showing the bending operation when the retainer 16 is formed of a material with low rigidity. Fig. 9 is a partially enlarged view showing the bending motion when the retainer 16 is formed of a material having high rigidity.

Initially, the retainer 16 is perpendicular to the outer surface of the housing body 12 (indicated by p in FIGS. 8 and 9).

Next, an external force is applied to the retainer 16 from the left in FIG. Then, the retainer 16 itself is bent by the position where the external force of the retainer 16 acts, or the joining part of the retainer 16 with respect to the housing main body 12 is bent. As a result, the width of the slit 34 gradually narrows, so that the retainer 16 contacts the contact portion 33 (indicated by q in Figs. 8 and 9).

Subsequently, when the external force is further added, the bent portion 37 contacts the contact portion 33 of the retainer 16 to concentrate the bending stress, and the bent portion 37 is bent. The curved retainer 16 contacts the bottom surface 35 of the recessed portion 24 and is stored in the recessed portion 24 (indicated by r in FIGS. 8 and 9). As a result, a gap 36 is formed between the retainer 16 and the bottom surface 35. In FIG. 8, since the rigidity of the retainer 16 is low, and the some notch 38 is formed, the space | gap 36 becomes narrow. On the other hand, in FIG. 9, since the rigidity of the retainer 16 is high, the space | gap 36 becomes wide.

In addition, the width and depth of the slit 34 may be appropriately determined. That is, when the width of the slit 34 is widened to make the depth shallow, the timing at which the retainer 16 is bent can be delayed. On the other hand, when the width of the slit 34 is narrowed to deepen it, the timing at which the retainer 16 is bent can be increased.

Moreover, when the depth of the slit 34 is deepened, this principle which makes the contact part 33 a support point requires large force to bend the retainer 16. As shown in FIG. On the contrary, if the depth of the slit 34 is made shallow, a small force may be sufficient for bending the retainer 16.

In addition, the depth, position, and number of the notches 38 may be appropriately determined.

In addition, the curvature of the contact part 33 may be suitably determined. That is, when the curvature is increased, the bent portion 37 can be bent sharply. On the other hand, when the curvature is reduced, the bent portion 37 can be bent gently, and the bent portion 37 can be brought into close contact with the contact portion 33, so that the bending angle of the bent portion 37 can be easily controlled.

As described above, by retaining the retainer 16 in the recess 24, the projection 18 of the retainer 16 is inserted into the retainer opening 26, so that the outer surface of the ridge 22 and the outer surface of the retainer 16. It is continuous with the outer surface of this housing main body 12 (refer FIG. 11).

Returning to Figs. 2 to 4, an extension 28 is provided near the connector opening 13 on one side (upper side in Fig. 2) of the side where the retainer 16 of the housing main body 12 is not provided. Formed. Corresponding to the expansion portion 28, the connector opening 13 is extended.

The inside of the housing main body 12 is provided with the some groove part 57 which reaches the connector opening 13 along the axial direction. When the receptacle connector is inserted into the connector opening 13, the groove 57 is engaged with the outer circumferential surface of the receptacle connector 30 to guide the inside of the housing main body 12 while preventing the receptacle connector 30 from rotating.

The expansion portion 28 has an inverted c shape when viewed from the side surface of the housing main body 12. The lock opening 29 which communicates with the inside of the housing main body 12 is formed in the part enclosed by the expansion part 28 of the housing main body 12. As shown in FIG. Moreover, the edge part of edge part which is not enclosed by the expansion part 28 of this lock opening 29 becomes an edge part. The lock opening 29 and the edge portion lock the receptacle connector 30 inserted into the connector opening 13 as will be described later. Also, a part of the groove 57 is shown in the lock opening 29 in FIG.

10 is a side view of the connector housing 10 in a state where the retainer 16 is inserted into the retainer opening 26. FIG. 11 is a partial cross-sectional view of the connector housing 10 in a state where the retainer 16 is inserted into the retainer opening 26 viewed from a direction different from that in FIG.

The housing main body 12 has a sealing ring accommodating chamber 25 as a component accommodating chamber in which the sealing ring 40 is accommodated, and a passage 31 extending along the axial direction from the sealing ring accommodating chamber 25 to communicate with the outside. Is formed. Moreover, the 2nd channel | path 32 which communicates the exterior with the sealing ring accommodation chamber 25 is formed in the sleeve 14 along the axial direction.

Moreover, the retainer opening 26 is provided in the position which opposes the channel | path 31, and mutually communicates with the channel | path 31. As shown in FIG. The retainer opening 26 is formed on the connector opening 13 side than the end of the connector opening 13 side of the sealing ring 40 accommodated in the sealing ring accommodation chamber 25.

The sealing ring 40 is in contact with the inner surface of the sealing ring accommodation chamber 25, and becomes substantially annular in cross section which extends along the inner periphery of the sealing ring accommodation chamber 25. As shown in FIG. The pressing force on the seal ring receiving chamber and the passage of the seal ring 40 is preferably low enough to smoothly insert the seal ring 40.                     

The sealing ring 40 is a rubber integrally formed in a cylinder, and has flexibility. The inner circumferential surface of the sealing ring 40 is enlarged and open toward both end portions from the center. The sealing ring 40 is formed with a plurality of annular irregularities on the inner circumferential surface and the outer circumferential surface to improve airtightness. Although NBR or silicone type rubber is mentioned as a rubber used for the sealing ring 40, an oil bleed material is more preferable.

The sealing ring 40 is arrange | positioned in the sealing ring accommodating chamber 25 by press-fitting, for example from a connector opening 13 side of the housing main body 12 using a press-fit jig etc.

When the retainer 16 is closed and the projection 18 having the lance 20 is inserted into the retainer opening 26, the lance 20 engages the opening inner edge 27. As a result, the closed state of the retainer 16 is maintained. At the same time, as shown in Fig. 11, the projection 18 protrudes into the passage 31 of the housing main body 12 to engage with the end face of the connector opening 13 side of the sealing ring 40 to seal the seal ring 40. ) Is prevented from falling off from the seal ring accommodation chamber 25. At this time, it is preferable that the contact pressure between the sealing ring 40 and the protrusion 18 is high enough to allow sufficient coupling to prevent the sealing ring 40 from being pulled out. Naturally, this contact pressure can be determined in relation to the projecting dimension and shape of the retainer 16 projection.

12 is a perspective view of the receptacle connector housing 50 of the receptacle connector 30.

The receptacle connector housing 50 is cylindrical and has a wire opening 51 into which the receptacle contact assembly 80 is inserted, and a connector opening 55 on the opposite side.                     

The receptacle connector housing 50 has a connector waterproof seal 53 on the connector opening 55 side. When the receptacle connector housing 50 is inserted into the connector housing 10, although not shown, the receptacle connector housing 50 clamps the sealing ring 40 with the sealing ring accommodation chamber 25 and the connector waterproof seal 53.

The receptacle connector housing 50 is provided with the spring member 59 in the wire opening side 51 side. This spring member 59 extends along the outer circumferential surface of the receptacle connector housing 50 from the wire opening 51 side of the receptacle connector housing 50 toward the connector opening 55 side. A ridge 58 is formed at the tip of the spring member 59. As the spring member 59 elastically deforms, the ridge 58 has a pressing force toward the out-of-plane direction of the outer circumferential surface of the receptacle connector housing 50.

The inclined surface which goes down toward the connector opening 55 side is formed in the connector opening 55 side of the ridge 58. On the wire opening 51 side of the raised portion 58, a stepped end surface perpendicular to the outer circumferential surface of the receptacle connector housing 50 is formed.

On the outer circumferential surface of the receptacle connector housing 50, a plurality of protrusions 56 extending along the axial direction are formed. These protrusions 56 are coupled to the grooves 57 of the connector housing 10. As a result, the receptacle connector housing 50 and the connector housing 10 can be prevented from rotating with each other, and the insertion of the receptacle connector can be guided.

When the receptacle connector housing 50 is inserted into the connector housing 10, the ridge 58 moves along the extension 28 of the connector housing 10 and begins to be exposed from the lock opening 29. When the receptacle connector housing 50 is inserted deeper, the stepped end face of the ridge 58 engages the edge portion of the lock opening 29. This can reliably prevent the receptacle connector 30 from being pulled out.

The procedure for assembling the connector structure 1 described above will be described with reference to FIG. First, the plug contact assembly 70 is inserted into the wire opening 15 of the connector housing 10 and the plug connector 100 is formed. Next, the receptacle contact assembly 80 is inserted into the wire opening 51 of the receptacle connector housing 50 to form the receptacle connector 30.

Then, the sealing ring 40 is attached to the receptacle connector, and in this state, the receptacle connector 30 is inserted into the connector opening 13 of the connector housing 10. Thereafter, the retainer 16 is closed to insert the projection 18 into the retainer opening 26 to hold the sealing ring 40.
