Assembly of plug connector and inflator connecting device

The present invention belongs to the technical field of electrical connectors, and relates to a plug connector fitted to a mating member and an assembly of an inflator connecting device provided with such a plug connector and the mating member.

Patent Document 1 discloses an electrical connection device having a latching element as follows. This comprises a first component 2 supporting a first electrical connector element 13, a second component 3 is engaged with the first component 2, and the second component 3 is a male type A female second electrical connector element 30 that engages the first electrical connector element 13 is supported. A short-circuit element 4 for short-circuiting the male first electrical connector element 13 is attached to the first component 2 in advance. The latching element 5 is latched in advance at the first latching position with respect to the second component 3. By pushing the latching element 5, the second component 3 is engaged with the first component 2, and at the same time, the first latching position is canceled, and the latching element 5 is further moved to the second latching element. Pushed into the stop position. At this second latching position, the latching element 5 eliminates the short circuit of the short-circuiting element 4 (reference numerals are cited from the same document).

Patent Document 2 discloses a female connector 400 provided with a slider 450 similar to a latching element in the electrical connection device of Patent Document 1 (reference numerals are cited from the same document).

Patent Document 3 discloses the following connector. That is, between the two female terminal fittings 15 accommodated in the female housing 11, a short-circuitable terminal 18 that can be bent and deformed is attached, and is in contact with both female terminal fittings 15 and held in a short-circuited state. . The other male housing 12 is provided with a lock arm 36 that can be tilted and displaced elastically, and the projections 38 get over the locking portion 41 and lock to the rear surface thereof, so that the housings 11 and 12 are held in a fitted state. It has come to be. An intermediate arm 46 that can be bent and deformed is provided above the short-circuit terminal 18. When the housings 11 and 12 are fitted while the lock arm 36 is tilted and displaced, and the projection 38 gets over the locking portion 41 and returns to the original posture, the intermediate arm 46 is bent downward by being pushed by the projection 38 and further short-circuited.

JP 2001-319747 A Japanese Patent Laid-Open No. 2002-151181 JP-A-8-250226 JP-A-10-92517 JP 2005-302715 A JP 2002-324638 A JP 2010-27522 A

In the electrical connection device having the latching element of Patent Document 1, the short-circuit element 4 is connected to the first component 2 prior to fitting the second component 3 to the first component 2. Although it will be attached, the installation workability at this time is not good. This attachment is performed by fitting the short-circuit insert 4 provided with the short-circuit clip 24 in the socket 11 of the first component 2 as disclosed in the embodiment of the document, for example. At that time, the first connector element 13 may be rubbed by the short-circuit clip 24 and may be damaged. Since the short-circuit clip 24 and the first connector element 13 are exposed to the outside, dust or the like may adhere to them, and in that case, the risk of the damage further increases. For this reason, the attachment is performed while the short-circuit clip 24 is bent sideways, but the workability is poor. Such a problem can occur in the female connector 400 of Patent Document 2 as well.

On the other hand, in the case of the connector of Patent Document 3, since the short-circuit terminal 18 is built in the female housing 11 in advance, an operation to be performed prior to fitting the female housing 11 and the male housing 12 is performed. It is unnecessary. Further, since the short-circuit terminal 18 is not attached to the male housing 12, there is no possibility that the tab 34 is rubbed by the short-circuit terminal 18 and they are not damaged. However, since the lock arm 36 is provided in the male housing 12 and the intermediate arm 46 is provided in the female housing 11, the movable member for bending the short-circuit terminal 18 is provided in both housings. The members cannot be concentrated on one housing and the other housing cannot have a relatively simple structure. Therefore, it is difficult to use a known connector or the like as the counterpart member. In addition, since these movable members are provided around the fitting portions in both housings, it is impossible to meet the demand for operating the movable members on the opposite side of the housing opposite to the fitting port.

The present invention has been made paying attention to such points, and the object thereof is to reinforce the fitting force with the mating member by being operated on the fitting side of the connector like the above-mentioned latching element. Assuming a plug connector provided with a guarantee member, the guarantee member functions as a movable member, and the short-circuit member is accommodated inside the connector and the operation / non-operation of the short-circuit member is switched by the movement of the guarantee member, The mounting of the short-circuit member to the mating member is unnecessary, the work prior to mating with the mating member is unnecessary, and the workability of the mating is improved, and the mating member has a relatively simple structure. It is an object of the present invention to provide a plug connector capable of expanding the possibility of using a known connector or the like and further operating the guarantee member on the non-fitting side.

The claw 132b is configured to be detached from the stopper 122b by being pushed toward the center portion of the plug portion 122 from 200, and when the operation portion 131 is operated, the plug portion 122 is connected to the counterpart member 200. The fitting and the reinforcement of the fitting force between the plug member 122 and the mating member 200 by the guarantee member 130 are continuously performed. Further, when the guarantee member 130 is moved from the second position to the first position, the claw 132b is returned to the original position by the reverse movement of the fitting. In this embodiment, when the plug connector 100 is applied to the mating member 200 so that the mating sides face each other, and the operating portion 131 is pushed to the mating side, as shown in FIG.
