The engaging member 113 is provided in a cantilever shape and extends along the fitting direction. In this embodiment, the engaging member 113 extends in the fitting direction, but may extend in the counter-fitting direction. The engaging member 113 is connected to the housing 110 through an elastically deforming connecting portion 113a so as to be able to tilt around an axis X that is a direction orthogonal to the fitting direction or the anti-fitting direction. Yes. The axis X is a virtual axis. In the case of this embodiment, the fitting member 113 is connected to the housing main body 111 so as to be able to tilt around the axis X via the connecting portion 113a.

  A protrusion 113b is provided at the end of the engagement member 113 that is closer to the free end than the connection portion 113a. The protrusion 113b protrudes outside the engagement member 113. The outer side of the engaging member 113 is a side farther from the central part of the fitting part 112 in the fitting member 113 in the fitting direction, and the opposite side is the inner side. The engaging member 113 is elastically deformed when the fitting portion 112 is fitted to the retainer 400 when the fitting portion 112 is fitted to the retainer 400 in the fitting direction. The socket 210 is constructed so as to be restored after getting over the convex portion of the socket 210 and to engage with a concave portion provided on the opposite side of the convex portion of the socket 210. Further, when the engaging member 113 pulls out the fitting portion 112 from the retainer 400 in the anti-fitting direction, the protruding portion 113b comes off the concave portion and rides on the convex portion of the socket 210. It is configured. However, the present invention also includes an embodiment in which the engagement member does not come off when engaged with the recess. FIG. 17 shows a modification of the electrical connector 100. In the case of the electrical connector 100, the protruding portion 113b protrudes to the inside of the engaging member 113. The engaging member 113 is elastically deformed when the fitting portion 112 is fitted into the retainer 400 when the fitting portion 112 is fitted into the retainer 400 in the fitting direction. It is configured to recover after overcoming the convex portion of 400 and engage with a concave portion provided on the opposite side of the retainer 400 with respect to the convex portion. Further, when the engaging member 113 pulls out the fitting portion 112 from the retainer 400 in the anti-fitting direction, the protruding portion 113b comes off the concave portion and rides on the convex portion of the retainer 400. It is configured. However, the present invention also includes an embodiment in which the engagement member does not come off when engaged with the recess. The convex part and the concave part are convex parts where the projecting part comes out in a direction crossing the fitting direction so that the protruding part hits when the engaging member moves in the fitting direction, A portion recessed along the direction intersecting with the fitting direction so as to fit the protruding portion is a concave portion. The concave portion of the socket 210 is the groove 212, but may be formed separately. Moreover, although the convex part of the said socket 210 is the said wall 211 which exists in the said fitting side rather than the said recessed part, you may provide the said convex part or the said recessed part in the other site | part of the said socket. In the case of the modified example in which the protruding portion protrudes to the inside of the engaging member, the convex portion is a portion on the fitting side of the fourth cylindrical portion 430, and the concave portion is the fourth cylindrical portion. Although it is the opening provided in 430, you may provide the said convex part or the said recessed part in the other site | part of the said retainer. The operating member may be provided by extending the engaging member to the opposite side of the free end from the connecting portion. In that case, when the operating portion of the engaging member is pushed or pulled and the engaging member is tilted with the connecting portion as a fulcrum, the protruding portion is detached from the concave portion. The retainer is pulled out in the anti-fitting direction. This is the same in the case of the modified example in which the protruding portion protrudes to the inside of the engaging member.

  The surface on the opposite side of the protrusion 113b of the engagement member 113 is closer to the engagement side toward the tip of the protrusion 113b, that is, toward the outer side of the engagement member 113. Inclined. In this way, when the housing 110 is pulled out to the non-fitting side, the protruding portion 113b is easily detached from the concave portion. In the modified example in which the protruding portion 113b protrudes to the inside of the engaging member 113, the surface of the protruding portion on the side opposite to the fitting side is directed toward the tip of the protruding portion, that is, the engagement member 113 What is necessary is just to incline so that it may approach the said fitting side as it goes inside. As described above, instead of or in addition to inclining the surface of the protrusion 113b of the engagement member 113 on the side opposite to the mating side, the anti-fitting side of the concave portion of the socket 210 is used. The surface facing toward may be provided so as to be inclined so as to approach the fitting side toward the inner side of the socket 210. Similarly, in the modified example in which the protruding portion protrudes to the inside of the engaging member, the surface of the retainer that faces the anti-fitting side of the recess is fitted to the retainer as it goes to the outside of the retainer. You may incline so that it may approach to the side. When the engagement member is engaged with the recess, it is not necessary to take such a configuration.

  And when the said fitting part 112 of the said housing 110 fits into the said retainer 400, the said protrusion part 113b of the said engagement member 113 is comprised so that it may hook on the said groove | channel 212 as said recessed part. Similarly, when the concave portion is provided in the retainer, the protruding portion of the engaging member is configured to be engaged with the concave portion of the retainer when the fitting portion of the housing is fitted to the retainer.

  As shown in FIGS. 2, 3, 4, and 6 to 14, the electrical terminals 120 are provided in a number corresponding to the number of the squib terminals 310.

Caulking. The connection structure may be, for example, a structure for press-contacting the outer conductor, a structure for piercing the outer conductor, a structure for soldering the outer conductor, or another structure. In this embodiment, the contact portion 121 is mounted inside the fitting portion 112 and the connection portion 122 is mounted inside the housing main body 111, so that the contact portion 121 is connected to the fitting portion 112. The connecting portion 122 extends in a direction perpendicular to the fitting direction, which is the longitudinal direction of the housing body 111, and the electrical terminal 120 is formed in an L shape. However, the electrical terminal may be formed in, for example, an I shape, a V shape, or other shapes, and the contact portion and the connection portion may be provided outside the housing. 18 and 19 show a modification of the electrical connector 100. FIG. In the case of the electrical connector 100, in addition to the pair of electrical terminals 120, another electrical terminal 120 '(not shown) is further provided. Other configurations are the same as those of the electrical connector of this embodiment. The other electrical terminal 120 ′ includes the contact portion 121 ′ provided on the fitting side and a connection portion (not shown) having a connection structure with another external conductor 500 ′. The contact portion 121 ′ protrudes from an opening provided in the fitting portion 112, and when the fitting portion 112 is fitted to the retainer 400, the contact portion 121 ′ becomes the wall of the socket 210. 211 is brought into conduction with the inflator housing 200. The other outer conductor 500 ′ is an electric wire having the same configuration as the outer conductor 500, but besides the electric wire, for example, a shielded cable or its element, for example, a flat flexible cable such as FFC or its element, or other conductive It includes conductive means with a body. The connecting portion of the other electric terminal 120 ′ has the same configuration as the connecting portion 122 of the electric terminal 120, and is connected to the other external conductor 500 ′ in the same manner as the connecting portion 122. Furthermore, there is a modification of the electrical connector 100 in which a shielded cable is connected. In this modification, for example, the signal line of the shielded cable is connected to the connecting portion 122 of the electrical terminal 120 as the external conductor 500, and the external conductor of the shielded cable is the other external conductor 500 ′ and the other Connected to the connecting portion of the electric terminal 120 ′.

Among them, for example, there is an embodiment of the electric terminal that conducts electricity with the outside in a non-contact manner.

  The lock member 130 is provided in the housing 110 so that the position relative to the housing 110 is movable between a first position and a second position on the opposite side of the first position. 6 to 8 show that the lock member 130 is in the first position, and FIGS. 9 to 11 show that the lock member 130 is in the second position. 12 to 14 show that the lock member 130 has returned to the first position. That is, as shown in FIG. 3 and FIG. 4, the housing body 111 is provided with a groove 111a that penetrates in a direction orthogonal to the fitting direction and is opened on the anti-fitting side. A main body 131 extending in a direction orthogonal to the fitting direction of the lock member 130 is fitted so as to be slidable in the fitting direction and the anti-fitting direction. When the locking member 130 falls to the fitting end of the groove 111a, the first position is taken, and when the locking member 130 moves from the first position to the anti-fitting side by a predetermined distance, The second position is taken. However, the lock member only needs to be provided somewhere in the housing so as to be movable between the first position and the second position on the opposite side of the first position. The structure of the housing or the lock member is not limited by the structure. For example, one of the housing and the lock member may be provided with a groove extending in the fitting direction and the anti-fitting direction, and the other may be provided with a protrusion that fits into the groove. When the lock member 130 is in the first position, the lock member 130 interrupts the elastic deformation by interrupting the first space 113c formed on the side of the engagement member 113 where the engagement member 113 is elastically deformed. When in the second position, it is configured to retract from the first space 113c and allow the elastic deformation of the engaging member 113 (see FIGS. 8, 11, and 14). That is, as shown in FIG. 3 and FIG. 4, the lock member 130 is opposite to the concave portion side in which the engagement member 113 is fitted with respect to the engagement member 113 when viewed from the fitting direction. A lock piece 132 is provided on the side, that is, the back side of the engagement member 113. In the case of this embodiment, the lock piece 132 is constituted by a plate-like member having a surface in the same direction as the back surface of the engagement member 113, but may be, for example, a rod shape or other shapes. The same number of the locking pieces 132 as the engaging members 113 are provided. As shown in FIGS. 8 and 14, when the lock member 130 is in the first position, the lock piece 132 interrupts the first space 113c to prevent the elastic deformation, as shown in FIG. Thus, when the lock member 130 is in the second position, the lock piece 132 is retracted from the first space 113c to allow the elastic deformation of the engagement member 113.

  As shown in FIGS. 3, 4, and 6 to 14, the elastic member 140 is provided on the housing 110 so as to push the lock member 130 to the first position. The elastic member 140 is provided between the housing 110 and the lock member 130. In the case of this embodiment, the elastic member 140 is formed in a rod shape from an elastic material. The elastic member 140 is made of a steel material, but may be other materials as long as it has elasticity. The elastic member may be, for example, a coil spring, a plate spring, a spring, a torsion bar, or another spring that elastically deforms under a load, or a plate shape made of an elastic material, for example. It may be a body, a rod-like body, or an object having another shape. The elastic member 140 is wound in the middle in order to reduce the size and increase the elastic restoring force, but there is a modification in which the wound portion is not provided. The first end 141 is locked to the housing body 111, and the second end 142 on the opposite side is locked to the lock member 130. The first end 141 may be locked to another part of the housing 110. The second end 142 is fitted in a groove provided on the end surface of the lock member 130 on the opposite side. The structure for attaching the end of the elastic member to the housing or the structure for attaching the end of the elastic member to the lock member is not limited by this embodiment. Each of the end portions may be attached to the housing or the lock member with, for example, fitting, fitting, hooking, integral molding, or other structure. When the lock member 130 is pushed from the first position to the second position, the elastic member 140 is elastically deformed, and the lock member 130 is pushed from the second position to the first position by elastic restoring force. It is configured as follows. It is preferable to provide a stopper for locking the lock member and the housing so that the position of the lock member 130 does not move to the fitting side from the first position. In the case of this embodiment, the main body 131 of the lock member 130 hits the fitting-side end of the groove 111a, thereby serving as a stopper. However, the present invention includes an embodiment of the electrical connector that does not include such a stopper. Such an embodiment includes, for example, an embodiment in which the lock member is held near the first position by the elastic member when the lock member is in the first position. In this embodiment, the elastic member 140 is provided so as to be elastically deformed mainly by receiving a bending load. However, the elastic member is elastically deformed by receiving, for example, a compressive load, a tensile load, or other loads. It may be provided as follows.

The facing surface facing the fitting side may be provided in the inflator housing, for example, in the socket. In that case, the said opposing surface is provided so that it may protrude toward the said center part of the said socket from the said wall of the said socket, for example. For example, the leg portion is provided on an outer peripheral portion of the lock member that is away from the central portion.

  The release member 152 extends to the fitting side. The release member 152 is formed in a rod shape, and the end portion on the opposite side of the release member 152 is connected to the lid 114 of the housing 110. However, the leg portion may be connected to any part of the housing, for example, the housing body, the fitting portion, or the engagement member, and the release member may be, for example, plate-shaped, or It may be formed in other shapes, for example, may be connected to the housing at a midway portion along the fitting direction, or at other portions. The same number of release members 152 as the leg portions 151 are provided. When the lock member 130 is in the first position, the release member 152 does not press the leg 151, and the release member 152 pushes the leg 151 as the lock member 130 moves toward the second position. When the locking member 130 is pushed to the side intersecting the fitting direction and the locking member 130 reaches the second position, the release member 152 pushes the fitting-side end of the leg portion 151 into the opposing surface 440 of the retainer.

However, it is also possible to provide an end edge of the facing surface that falls to the side opposite to the mating side on the side of the facing surface that is close to the center of the retainer, and the release member on the outside of the leg portion. The inside of the leg portion 151 is a side of the leg portion 151 that is close to the central portion of the fitting portion in the fitting direction, and the opposite side is the outside. Further, when the facing surface facing the fitting side is provided in the inflator housing, for example, the edge of the facing surface that falls to the opposite mating side is on the side of the facing surface near the center of the socket. The release member may be provided on the outer side of the leg, or an edge of the opposing surface that falls to the opposite mating side is provided on the side of the opposing surface far from the center of the socket, and the release is performed. You may provide a member inside the said leg part.

  6 and 7, when the electric connector 100 having the lock member 130 in the first position is placed on the retainer 400, the end of the leg portion 151 on the fitting side is the retainer. The locking member 130 interferes with the retainer 400 along the fitting direction in contact with the facing surface 440 of 400. When the housing 110 is pushed in the fitting direction, the lock member 130 moves from the first position to the second position, but the interference state is maintained until the position immediately before the second position. . Further, as shown in FIGS. 9 and 10, when the housing 110 is pushed in the fitting direction and the lock member 130 reaches the second position, the fitting of the legs 151 is performed. The side end is detached from the facing surface 440 and falls to the fitting side, whereby the interference is released and the movement of the lock member 130 to the first position is permitted. When the upper inflator housing is provided with the facing surface, the leg portion is configured to contact the facing surface, and the leg portion is removed from the facing surface by the release member, the same effect as described above is obtained. Demonstrated. In the case of the above embodiment, the control mechanism is configured by the leg 151 and the release member 152. When the lock member is between the first position and the position immediately before the second position, the fitting is performed. The locking member is caused to interfere with the retainer or the inflator housing along the mating direction, and when the locking member reaches the second position, the interference is released and the movement of the locking member to the first position is permitted. The control mechanism may be realized by another configuration as long as it is to be realized.

A housing main body, a fitting portion provided in the housing main body and fitted to a retainer attached to a socket that is recessed from the fitting-side surface of the inflator housing toward the non-fitting side; and the fitting portion An engaging member that is elastically deformed when fitted to the retainer and gets over the socket or the convex portion of the retainer and then elastically restores and engages with the concave portion provided on the opposite side of the convex portion. A housing having
A contact portion that comes into contact with the squib terminal that rises from the bottom of the socket toward the fitting side when the fitting portion of the housing is fitted to the retainer, and intersects the fitting direction from the housing. An electrical terminal provided in the housing having a connecting portion connected to the outer conductor led out in a direction to
The housing is provided movably between a first position and a second position on the opposite side of the first position, and when in the first position, the engagement member is engaged. The member cuts into the first space formed on the elastically deforming side to prevent the elastic deformation, and when in the second position, retracts from the first space and allows the elastic deformation of the engaging member. A locking member,
An elastic member provided on the housing to push the locking member to the first position;
When the locking member is between the first position and the position immediately before the second position, the locking member is caused to interfere with the retainer or the inflator housing along the fitting direction, and the locking member is moved to the first position. A control mechanism for releasing the interference and allowing the lock member to move to the first position when reaching the second position;
The housing is provided so as to form a second space in which the electrical terminal and the outer conductor are disposed by being opened to the opposite mating side.
The squib connection device in which the lock member and the elastic member are arranged in a third space included in a space excluding the second space when viewed from the fitting direction in the housing.
