By the way, in the above-mentioned connector, due to a dimensional tolerance at the time of manufacturing or the like, a positional deviation (rattling) may occur between the holder and the shunt ring when they are assembled. If this rattling is within the range expected at the time of design, there is usually no substantial effect on the quality of the connector. However, for example, if the shunt ring and surrounding objects come into strong contact during transportation of the inflator or assembly work to the vehicle, the shunt ring may be displaced by the amount of rattling, and the shunt ring and the holder may be damaged. There is sex. Since it is used as an inflator for airbag systems, it is desirable to increase the strength of the connector even against such unexpected contact. Naturally, it is not limited to the connector used for the inflator, and it is preferable that the strength against similar contact is high. As described above, from the viewpoint of further increasing the strength of the connector, it is desired to suppress rattling between the members constituting the connector as much as possible.

FIG. 3 is a perspective view of the connector according to the present embodiment and the mating side connector as viewed from the rear side.

As shown in FIGS. 1 to 3, the connector 12 according to the present embodiment is connected to the mating connector 11. The connector 12 and the mating connector 11 constitute an electric connector for an in-vehicle airbag system. The connector 12 is an inflator-side connector provided in the inflator of the airbag system, and the mating connector 11 is a wire harness-side connector.

The connector 12 has a fitting port 12a, and the mating connector 11 has a connecting portion 11a. The connector 12 is connected to the mating connector 11 by fitting the connecting portion 11a of the mating connector 11 into the fitting port 12a.

The connecting portion 11a of the mating connector 11 is integrally formed with the housing 20. A terminal and a ferrite core (not shown) are assembled from the back surface of the housing 20. A cover 30 is attached to the back surface of the housing 20, which covers the terminals and the ferrite core. The terminals are housed in a terminal storage chamber (not shown) formed in the connection portion 11a. An insertion hole 22a that communicates with the terminal accommodating chamber is formed at the tip of the connection portion 11a. The electric wire 43 of the wire harness is connected to the terminal, and the electric wire 43 is pulled out from the lower end of the housing 20. The ferrite core is mounted on the electric wire 43, and prevents noise current from flowing through the electric wire 43 due to various electromagnetic waves from the outside.

FIG. 4 is an exploded perspective view of the connector according to the present embodiment.
As shown in FIG. 4, the connector 12 according to the present embodiment to which the mating connector 11 is connected has a holder (first component) 70 and a shunt ring (second component) 80. The holder 70 is attached to an ignition terminal portion provided in the airbag inflator.

The holder 70 is formed in a bottomed cylindrical shape having a cylindrical portion 71 formed in a cylindrical shape and a bottom portion 72 provided on one side of the tubular portion 71. The inside of the tubular portion 71 of the holder 70 is a hollow portion 73, and the hollow portion 73 has an opening 73a on the fitting side of the mating connector 11. Two pins (ignition terminal portions) 75 are fixed to the bottom portion 72 of the holder 70 at intervals, and these pins 75 extend toward the opening 73a side. The pin 75 is made of a conductive metal material and is connected to a circuit on the inflator side of the airbag system.

The shunt ring 80 is molded from synthetic resin. The shunt ring 80 is fitted into the hollow portion 73 of the holder 70 through the opening 73a and mounted. As a result, the holder 70 and the shunt ring 80 are assembled so as to face each other in the mating direction with the mating connector 11.

The shunt ring 80 has a main body portion 81, and a fitting port 12a is formed in the main body portion 81. Then, the connecting portion 11a of the housing 20 is fitted into the fitting port 12a. When the shunt ring 80 is attached to the holder 70, the pin 75 is arranged at the fitting port 12a of the main body 81.

To fit the mating connector 11 to the connector 12, the connecting portion 11a of the mating connector 11 is inserted into the fitting port 12a of the main body 81 of the connector 12. In this way, the pin 75 of the connector 12 is inserted into the insertion hole 22a formed in the connection portion 11a of the mating connector 11. As a result, the pin 75 is inserted into the terminal, and the pin 75 and the terminal are electrically connected.

Next, the structures of the holder 70 and the shunt ring 80 constituting the connector 12 will be described in detail.
FIG. 5A is a front view of the connector according to the present embodiment, and FIG. 5B is a front view of the shunt ring. 6 (a) is a cross-sectional view taken along the line AA in FIG. 5, and FIG. 6 (b) is an enlarged view of part C in FIG. 6 (a). 7 (a) is a sectional view taken along line BB in FIG. 5, FIG. 7 (b) is an enlarged view of part D in FIG. 7 (a), and FIG. 7 (c) is an enlarged view of part E in FIG. 7 (a). It is a figure. 8 (a) is an enlarged perspective view at the tip of the connector, and FIG. 8 (b) is a side view at the tip of the connector.

As shown in FIGS. 5 (a), 6 (a), and 7 (a), the holder 70 of the connector 12 includes a contact surface 76. The contact surface 76 is an end surface of the opening end of the holder 70 having the opening 73a, and faces the one-way A1 in the fitting direction in the tubular portion 71 of the holder 70. Further, the holder 70 is formed with an annular groove portion 77 on the inner peripheral surface of the tubular portion 71. The annular groove portion 77 is formed near the open end of the holder 70.

The main body 81 of the shunt ring 80 is inserted into the hollow portion 73 of the holder 70. As a result, the shunt ring 80 is attached to the holder 70. The shunt ring 80 has a flange portion 84. The flange portion 84 is formed so as to project toward the outer peripheral side of the end surface 82 side of the main body portion 81. The outer diameter of the flange portion 84 is larger than the inner diameter of the tubular portion 71 of the holder 70. The flange portion 84 is formed along the circumferential direction and overlaps the contact surface 76 formed by the end surface of the open end of the holder 70. The surface of the flange portion 84 that overlaps and faces the contact surface 76 of the holder 70 is the contact surface 85. The flange portion 84 has a flange inclined surface 86. The flange inclined surface 86 is formed of a surface of the flange portion 84 opposite to the contacted surface 85. The flange inclined surface 86 is inclined so as to approach the end surface of the open end of the holder 70, which is the contact surface 76 of the holder 70, as the distance from the main body portion 81 increases. A pair of flange portions 84 are formed, and gap portions G are provided between the peripheral ends of these flange portions 84. These gaps G are arranged at positions facing each other.

As shown in FIG. 7B, the main body 81 has a main body inclined surface 87 in the gap G between the ends of the flange 84. The main body inclined surface 87 is formed on the outer peripheral side of the main body portion 81. The inclination angle of the main body inclined surface 87 is larger than that of the flange inclined surface 86 of the flange portion 84. The main body inclined surface 87 is not exposed to the unidirectional A1 in the fitting direction with the mating connector 11 with respect to the flange inclined surface 86.

The shunt ring 80 has an elastic arm 91 and a locking arm 95 in the gap G, respectively. In each gap G, the elastic arm 91 and the locking arm 95 are adjacent to each other. Both the elastic arm 91 and the locking arm 95 extend in one direction A1 in the fitting direction. Further, both the elastic arm 91 and the locking arm 95 project to the outer peripheral side of the main body 81.

As shown in FIG. 6B, the elastic arm 91 has an urging surface 92. The urging surface 92 is formed so that the urging surface 92 goes from the extending end of the elastic arm 91 (that is, the tip end portion of the one-way A1 in the fitting direction in FIG. 6B) toward the other-way A2 in the fitting direction. It is tilted so that it gradually projects outward. As shown in FIG. 7B, the locking arm 95 has a locking surface 96. The locking surface 96 is a surface substantially orthogonal to the fitting direction.

As shown in FIGS. 8A and 8B, the shunt ring 80 has a pair of protrusions 97 on the end surface 82 of the one-way A1 in the main body 81. These protrusions 97 project from the end surface 82 of the main body 81. The outer peripheral side of the shunt ring 80 is inclined in these protrusions 97. As a result, these protrusions 97 have a tapered shape in which the cross-sectional area decreases as the protrusion height increases.

The shunt ring 80 is a connection surface whose end surface 82 is abutted against the connection portion 11a of the mating connector 11 and is positioned. As shown in FIG. 8B, a minute step 83 is provided between the end surface 82 and the flange portion 84, which are connection surfaces, so that the end surface 82 and the flange portion 84 are discontinuous. Has been done. The step 83 has a dimension of about 0.1 mm along the fitting direction. By providing the step 83, the end face 82 can be made into a highly accurate smooth surface when the shunt ring 80 is formed. Therefore, the positioning accuracy when connecting to the mating connector 11 can be improved.

When the shunt ring 80 having the above structure is fitted into the hollow portion 73 of the holder 70, the elastic arm 91 and the locking arm 95 abut on the inner peripheral surface of the shunt ring 80 and elastically deform toward the center side. After that, when the shunt ring 80 is fitted into the holder 70 to the mounting position and the shunt ring 80 is assembled to the holder 70, the ends of the elastic arm 91 and the locking arm 95 enter the annular groove portion 77 of the holder 70 (FIG. 6). (A) and FIG. 7 (a)).

As shown in FIG. 6B, by assembling the shunt ring 80 to the holder 70, the elastic arm 91 whose end is inserted into the annular groove portion 77 has its urging surface 92 in the fitting direction of the annular groove portion 77. Always in contact with the unidirectional A1 side edge 77a in the above, and is elastically deformed by being pressed inward by the edge 77a. As a result, the edge portion 77a of the annular groove portion 77 is maintained in a state of being pressed against the urging surface 92 by the elastic force of the elastic arm 91. Then, the holder 70 is urged in one direction A1 in the fitting direction by the component force of the pressing force applied from the urging surface 92 to the edge portion 77a of the annular groove portion 77, and the shunt ring 80 is urged in the fitting direction. Is urged to the other direction A2. Therefore, the contact surface 76 of the holder 70 and the contact surface 85 of the shunt ring 80 are maintained in contact with each other by the urging force generated by the elastic arm 91, and the lifting of the shunt ring 80 from the holder 70 is suppressed. To.

Further, as shown in FIG. 7B, by assembling the shunt ring 80 to the holder 70, the locking surface 96 of the locking arm 95 having the end portion inserted into the annular groove portion 77 forms the annular groove portion 77. It is arranged so as to face the wall surface 77b on the one-way A1 side in the fitting direction. As a result, when the shunt ring 80 assembled to the holder 70 is displaced in one direction A1 in the fitting direction against the urging force generated by the elastic arm 91, the locking surface 96 of the locking arm 95 is annular. It abuts on the wall surface 77b of the groove 77. As a result, the holder 70 and the shunt ring 80 are maintained in an engaged state with each other. Therefore, the connector 12 to which the mating connector 11 is fitted is engaged by the locking arm 95 so as not to be released from the mating with the mating connector 11.

As described above, according to the connector 12 according to the present embodiment, after the holder 70 and the shunt ring 80 are assembled, not only the holder 70 and the shunt ring 80 are engaged with each other, but also the contact surface of the holder 70 An urging force is generated so that the contact surface 85 of the shunt ring 80 and the contact surface 85 of the shunt ring 80 are maintained in contact with each other. Therefore, the position shift between the holder 70 and the shunt ring 80 is unlikely to occur during transportation or the like.

Therefore, the connector 12 according to the present embodiment can be applied to a connector for an airbag that requires a high safety standard.

In particular, by making the mechanism that generates the urging force and the mechanism that engages with each other as separate members, the degree of freedom in designing each mechanism can be increased, and the arrangement and shape suitable for each mechanism can be selected.

Specifically, as a mechanism for generating an urging force, the urging surface 92 of the elastic arm (elastic portion) 91 provided on the shunt ring 80 is provided at the edge portion (pressed portion) of the annular groove portion 77 provided on the holder 70. By assembling while pressing against 77a, an urging force is generated between the holder 70 and the shunt ring 80. Further, as a mechanism for engaging, the locking surface 96 of the locking arm (locking portion) 95 different from the elastic arm 91 is engaged with the wall surface (locked portion) 77b of the annular groove portion 77 to engage the two. Can be engaged.

Further, the inclined surfaces 86 and 87 provided on the flange portion 84 and the main body portion 81 allow the external force to be passed along the inclined surfaces 86 and 87 even if the external force is applied to the shunt ring 80 during transportation or the like. Further, even if a large external force that cannot be parried is applied, the inclined surface 86 of the flange portion 84 is deformed before the inclined surface 87 of the main body portion 81, so that the fitting port 12a of the mating connector 11 is used. The main body 81 to be imaged is unlikely to be deformed.

Moreover, when an external force is applied to the end surface 82 of the shunt ring 80, the protrusion 97 is preferentially deformed, so that the deformation of the fitting port 12a of the mating connector 11 can be suppressed. In particular, since the protrusion 97 has a tapered shape, the deformed protrusion 97 has a fitting port as compared with the case where the protrusion 97 is deformed by an external force when the protrusion 97 does not have a tapered shape (such as a mere square pillar). It is unlikely that it will be pushed out toward 12a.

The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, and the like. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

For example, in order to generate an urging force for abutting the contact surface 76 of the holder 70 and the contact surface 85 of the shunt ring 80, an annular groove portion is formed on the shunt ring 80 side and an elastic arm is provided on the holder 70 side. It may be provided.

Further, in the above embodiment, two elastic arms 91 are provided at opposite positions, but one elastic arm 91 is provided, and the contact surface 76 of the holder 70 and the shunt ring 80 are hit by the one elastic arm 91. The structure may be such that an urging force is generated to bring the contact surface 85 into contact with the contact surface 85.

Further, in the above embodiment, the shunt ring 80 is provided with the elastic arm 91 having the urging surface 92 and the locking arm 95 having the locking surface 96, respectively, but as shown in FIG. 9, the shunting surface 92 and the engagement surface 92 are provided. An arm 90 having a shunt surface 96 may be provided. When the shunt ring 80 provided with the arm 90 is assembled to the holder 70, the urging force generated by the urging surface 92 of the arm 90 constantly contacting the unidirectional A1 side edge portion 77a in the fitting direction of the annular groove portion 77. The contact surface 76 of the holder 70 and the contact surface 85 of the shunt ring 80 are maintained in contact with each other. Further, when the shunt ring 80 is displaced to the unidirectional A1 in the fitting direction against the urging force, the locking surface 96 of the arm 90 comes into contact with the wall surface 77b of the annular groove portion 77, and the holder 70 and the shunt ring 80 Are kept engaged with each other.

Further, as the protrusion 97 protruding from the end surface 82 of the main body 81 of the shunt ring 80, as shown in FIG. 10, by inclining the edge portion on the fitting port 12a side, the cross-sectional area increases as the protrusion height increases. It may have a tapered shape that becomes smaller.
