【Example】

 Hereinafter, embodiments embodying the present invention will be described in detail with reference to FIGS. FIG. 1 shows the overall structure of the connector housing 4 together with the dummy cap 1.

The dummy cap 1 is composed of a cap portion 2 that is coupled to the connector housing 4 and a clip portion 3 that is detachably engaged with a vehicle body 5 that is a fixing member.

The connector housing 4 is a female type that is coupled to the cap portion 2, and has a plurality of female terminals (not shown) arranged therein. These female terminals were used as test terminals for the electronic control circuit of the automobile in this example. On both sides of the connector housing 4, a pair of guide ridges 11 and 12 for coupling are provided so as to protrude along the longitudinal direction thereof. Further, a pair of side walls 13 are provided upright on the rear end side of the insertion on the upper surface portion of the connector housing 4, and a cantilever-like elastic deformation fixed to the connector housing 4 at the insertion end side between the side walls 13. The piece 14 is arranged so as to be vertically movable. A pressing operation portion 15 is formed at a rear end portion of the elastically deformable piece 14 inserted, and a through hole 16 is formed in front of the pressing operation portion 15.

On the other hand, as shown in FIG. 3, the cap portion 2 is provided with an opening portion 21 which is opened at the rear end side in the longitudinal direction and into which the connector housing 4 can be fitted, and the opening portion 21 The front end side in the longitudinal direction of is closed by a partition wall 22. A guide groove (not shown) that fits into the guide protrusions 11 and 12 is provided on the inner side and the bottom of the opening 21. An engaging projection 23 is provided on the upper surface of the opening 21 on the rear end side in the longitudinal direction so as to project downward.

Here, the coupling of the cap portion 2 and the connector housing 4 is performed as follows. That is, the insertion tip side of the connector housing 4 faces the opening 21 of the cap portion 2, and the guide protrusions 11 and 12 of the connector housing 4 are inserted along the guide groove of the opening 21. Eventually, when the insertion front end side (terminal open side) of the connector housing 4 approaches the partition wall 22 of the cap portion 2, the elastic deformation piece 14 comes into contact with the engagement projection 23 and bends downward, and then the engagement projection 23 It engages with the through hole 16 of the elastic deformation piece 14. In this way, the connector housing 4 is joined to the cap portion 2.

In order to separate the cap portion 2 and the connector housing 4, the pushing operation portion 15 is pushed downward. Then, the elastically deformable piece 14 bends downward, and the engaging projection 23 and the through hole 16 are dissociated, so that the connector housing 4 can be detached by pulling it out from the cap portion 2.

Next, the clip portion 3 that detachably attaches the dummy cap 1 to the vehicle body 5 will be described. As shown in FIG. 3 and FIG. 1, the clip portion 3 has a central wall portion 32 orthogonal to a hanging wall 31 that integrally hangs from the bottom surface 24 of the cap portion 2, that is, the longitudinal direction of the cap portion. Are integrally formed along the. The clip portion 3 is formed symmetrically with respect to the central wall portion 32. That is, the insertion base portion 41 is formed at the lower end of the central wall portion 32, and the insertion base portion 41 has the elastic locking portions 41a which can be recessed and deformed on both sides thereof and extend obliquely upward. An engaging step 43 is formed at the upper end of each elastic locking portion 41a so that it can be engaged with an engaging hole 50 penetrating the vehicle body 5. A pair of arm portions 42 for operation continue from the engagement step portion 43, and both arm portions 42 extend outward from the cap portion 2, and their ends are finger pads for operating the knob. The portion 46 is formed. Thus, the arm portions 42 can be entirely deformed into a recess by operating the finger contact portion 46, and the engagement step portion 43 and the engagement hole 50 can be disengaged from each other.

A pair of edge portions 51 are formed on the lower sides of both side surfaces of the cap portion 2 along the longitudinal direction of the cap portion 2, and a downward inclined piece 52 inclined obliquely downward from the edge portion 51 is formed. One pair extends below both sides of the cap portion 2. These downwardly inclined pieces 52 cooperate with the engagement step portion 43 of the clip portion 3 to engage with the vehicle body 5.

Next, the engagement / disengagement operation of this embodiment will be described with reference to FIGS. 4 (a), 4 (b) and 4 (c).

Here, the connector housing 4 having a built-in terminal, which is a test terminal, is usually coupled to the dummy cap 1 and fixed to the vehicle body 5, and is removed from the vehicle body 5 only when necessary, such as when an electronic control circuit is inspected. When it is dissociated and released from the dummy cap 1, it is used in combination with a connector housing (not shown) connected to the inspection device on the other side.

First, the operation of engaging the vehicle body 5 will be described. The connector housing 4 is connected to the cap portion 2 as described above. As a result, the insertion tip end side (terminal opening side) of the connector housing 4 is protected from the outside by the cap portion 2. Next, as shown in FIG. 4A, the cap portion 2 is gripped, the insertion base portion 41 is opposed to the engagement hole 50 of the vehicle body 5, and the insertion is performed by pressing. Then, as shown in FIG. 4B, the elastic locking portion 41 a elastically deforms, and the engagement step portion 43 starts to be inserted into the engagement hole 50. Further, when the pressing insertion is continued, the engagement step portion 43 is completely engaged with the edge of the engagement hole 50 as shown in FIG. 4 (c). At this time, the lower inclined piece 52 abuts on the upper side of the vehicle body 5 and generates a force for pulling the clip portion 3 upward, so that the engagement step portion 43 and the engagement hole 50 are engaged more reliably. Becomes

In this way, the clip portion 3 is engaged with the vehicle body 5, and the cap portion 2 formed integrally with the clip portion 3 is also engaged with the vehicle body 5. Therefore, the clip portion 3 is connected to the cap portion 2. The connector housing 4 is also securely engaged with the vehicle body 5.

Next, the dissociation operation will be described. As shown in FIG. 4C, in a state where the clip portion 3 is engaged with the vehicle body 5, the operator holds the finger contact portions 46 from both sides toward the center of the substantially horizontal direction. Then, the acting force is transmitted through the arm portion 42, and the elastic locking portion 41a begins to elastically deform, and as shown in FIG. 4 (b), the engagement step portion 43 and the engagement hole 50 of the vehicle body 5 are separated from each other. The engagement is disengaged. Therefore, when the clip part 3 is separated from the vehicle body 5 while holding the finger contact part 46, the clip part 3 is pulled out from the vehicle body 5 as shown in FIG. After that, the connector housing 4 is separated from the cap portion 2 as described above. As a result, the insertion tip side of the connector housing 4 is opened, so that the built-in terminal and the inspection device side can be connected.

As described above, according to this embodiment, since the clip portion 3 that engages with the vehicle body 5 is formed integrally with the cap portion 2, when the dummy cap 1 is disengaged from the vehicle body 5, It is possible to detachably engage with the vehicle body 5 by an extremely easy operation such as holding the finger contact portion 46 of the cam portion 42. This contributes to the improvement of work efficiency and has a particularly remarkable effect because the work can be surely and easily removed even if the work space cannot be fully secured or the work location cannot be visually checked directly.

Further, since the clip portion 3 is integrally molded with the cap portion 2, the attachment / detachment function which is easy to operate can be realized with a small number of parts.

Further, since the applied plate thickness of the clip portion 3 can be adjusted by setting the positions of the engagement step portion 43 of the arm portion 42 and the lower inclined piece 52 extending from the edge portion 51, the vehicle body 5 of various specifications can be adjusted. It can respond to the plate thickness on the side.

In the structure of the present embodiment, the arm portion 42 of the clip portion 3 is arranged symmetrically with respect to the central wall portion 32, but the arm portion may be provided on only one of the left and right sides. Good.

Further, instead of the arm portion 42 of the present embodiment as a disengagement means of the clip portion 3, a mechanism for elastically deforming the clip portion 3 by a lever action, or a clip by rotation of a rotating body having a cam surface on the outer periphery is rotated. Any mechanism that can easily elastically deform the clip portion 3, such as a mechanism that elastically deforms the portion 3, can be similarly applied.
