Next, using the slide member 3, (1) When fitting connector 2 to JB1 (2) When disconnecting connector 2 from JB1 after mating Will be explained respectively.

(1) When fitting the connector 2 into the JB1 First, as shown in FIG. 7, the female terminal 6 is inserted into the connector 2 and the male terminal 7 is inserted into the JB1. As the upper end 31a of the fitting passive slope 31 of the operating arm 4 coincides with the lower end 11a of the fitting driving slope 11 of the slide member 3 (hereinafter, this state is referred to as the temporary locking state of the operating arm 4),
The operation arm 4 is inserted into the insertion hole 43 of JB1 from the insertion hole 42 side.

Secondly, the guide 15 of the slide member 3
After inserting a from the groove 46a of the guide rail 46 of JB1, the slide member 3 is pushed toward the insertion hole 43 of the connector 2 as shown in FIG. Lower end 12a of disengagement drive slope 12 and lower end 11 of fitting drive slope 11
a and the tip 13a of the rail 13 are inserted through the insertion hole 4 respectively.
When reaching the peripheral edge 43 a of the sliding member 3, the locking arm 14 a of the slide member 3 engages with the temporary locking protrusion 44. As a result, the slide member 3 is temporarily locked to the JB1.

Third, from the temporarily locked state of the slide member 3, the slide member 3 is moved to the guide rail 46 as shown in FIG.
When pushed in along the X direction (see FIG. 7), the engagement between the locking arm 14a and the temporary locking protrusion 44 is released, and
The lower end 11a of the fitting driving slope 11 is a fitting passive slope 31.
Hit the upper end 31a of the.

When the slide member 3 is further pushed in the X direction, the fitting driving slope 11 slides on the fitting passive slope 31. At the same time, the passive slope 3 for fitting is provided by action / reaction.
1 receives an external force F from the fitting drive slope 11, the operation arm 4 gradually moves in the Y direction, and the rail 13 inserts the insertion space 36.
Begin to enter (see Figure 5). As a result, the operation arm 4 is gradually pulled out from the insertion hole 43, and the connector 2 gradually enters the insertion hole 42.

Finally, when the locking arm 14a engages with the main locking projection 45 and the slide member 3 is finally locked to JB1, the rail 13 is inserted into the insertion space 36 (see FIG. 5). (Refer to FIG. 3) and the operation arm 4 is inserted into the insertion hole 4
3 is automatically pulled out, and the connector 2 is set in the insertion hole 42. As a result, the male terminal 7 of JB1 and the female terminal 6 of the connector 2 are electrically connected in a state in which the fitting driving slope 11 and the fitting passive slope 31 are in contact with each other. JB1
The disengagement drive slope 12 and the disengagement passive slope 32 do not come into contact with each other when the connector 2 and the connector 2 are fitted together.

(2) When the connector 2 is disengaged from the JB1 after the fitting, first, as shown in FIG. 10, when the slide member 3 is pulled out in the X'direction, the locking arm 14a and the main locking projection 45 are pulled out. The main locking state of and is disengaged, and the electrical connection between the male terminal 7 in the JB1 and the female terminal 6 in the connector 2 is disconnected. The fitting drive slope 11 and the fitting passive slope 31 are separated from each other, and the disengagement drive slope 12 and the disengagement passive slope 3 are separated.
Two hits.

When the slide member 3 is further pulled out in the X'direction, the disengagement drive slope 12 slides on the disengagement passive slope 32 as shown in FIG. Along with that, the passive slope 32 for separation
However, the operation arm 4 receives the external force F ′ from the detaching drive slope 12 due to the action / reaction, and the operation arm 4 moves in the Y ′ direction (into the insertion hole 43).
Gradually pulled in. As a result, the connector 2 gradually begins to separate from the insertion hole 42.

As shown in FIG. 12, when the locking arm 14a engages with the temporary locking projection 44 and the slide member 3 is temporarily locked to JB1, the upper end 32a of the detaching passive slope 32 and the detaching drive slope. The lower end 12a of 12 is in contact with it. At this time,
The operation arm 4 is automatically pulled completely into the insertion hole 43, and the detaching passive slope 32 and the detaching drive slope 12 are not in contact with each other, that is, the operation arm 4 is temporarily locked as described above.
Comes.

When the operating arm 4 is temporarily locked, the connector 2
When the connector 2 is pulled out from the insertion hole 42, the connector 2 is completely detached from the JB1. It should be noted that the fitting drive slope 11 and the fitting passive slope 31 do not come into contact with each other in the state of being separated.

Therefore, by pushing or pulling the slide member 3 into or from the operating arm 4 of the connector, the JB1 and the connector 2 can be easily fitted or released. As a result, the work of fitting or disconnecting the JB1 and the connector 2 is simplified as compared with the related art. Also,
Since the temporary locking protrusion 44 and the main locking protrusion 45 for locking the slide member 3 to JB1 are integrally formed on JB1, reduction of the number of parts and reduction of manufacturing cost can be achieved as compared with the conventional case. it can. Furthermore, since the fitting or disengagement of the JB1 and the connector 2 is performed only by the movement of the slide member 3, the fitting or disengagement work can be performed with a weak force.

[0027]

As described above, according to the first aspect of the present invention, at the time of the fitting operation, the slide member moves one of the structures, so that the fitting driving slope of the slide member and the insertion slope are inserted. Since the pair of structures are fitted to each other by sliding on the passive slope for fitting of the operating arm projected from the hole, the fitting of the pair of structures can be automatically and easily performed only by moving the slide member. Done . Also, since the sliding takes place by contact with a detaching passive slope with fitting driving slope forces occurring during the fitting operation is distributed throughout the surface. As a result, the fitting work can be performed with a weaker force as compared with the related art . Well
Also, when detaching work, the sliding member is one
By moving the body, you can
Surface and the passive slope for detaching the operating arm protruding from the insertion hole
It slides and the pair of fitted structures are released.
Disengagement of a pair of fitted structures only by moving the ride member
Is done automatically and easily. Also, sliding is a drive for disengagement.
Since it is performed by contact between the slope and the passive slope for separation,
The force generated during work removal is distributed over the entire surface. By this
Therefore, it is necessary to perform the detaching work with a weaker force than in the past.
You can Therefore, mating and dismounting work is simpler than before
To be done.

According to the second aspect, when the slide member moves one of the structures, the disengagement drive slope of the slide member and the disengagement passive slope of the operation arm protruding from the insertion hole slide, Since the pair of fitted structure bodies are separated, the pair of fitted structure bodies are automatically and easily separated by only moving the slide member. As a result, the detaching work can be performed with a weaker force than in the conventional case. Further, since the sliding is performed by the contact between the detaching drive slope and the detaching passive slope, the force generated during the detachment work is dispersed over the entire surface. As a result, the detaching work can be performed with a weaker force than in the conventional case. Therefore, the detachment work is also simplified as compared with the related art.

According to the third and the fourth aspects, the fitting driving slope and the detaching passive slope face the direction in which the operation arm is pulled out from the insertion hole, and the detaching driving slope and the fitting passive slope are located in the operating arm. Since it faces in the direction opposite to the direction of pulling out, the mating drive slope of the sliding member that moves when the pair of structures is mated pulls out the mating passive ramp of the manipulating arm protruding from the insertion hole of the manipulating arm. Automatically pull in the direction.

Further, when the pair of fitted structures are released, the detaching driving slope of the sliding member moves the detaching passive slope of the operating arm protruding from the insertion hole in the direction opposite to the pulling-out direction of the operating arm. Pull automatically. As a result, due to the movement of the slide member, the other structural body is pulled to the one structural body during the fitting operation, and the other structural body is separated from the one structural body at the time of disengagement. Therefore, the fitting and dismounting work of the pair of structures can be easily and automatically performed only by moving the slide member.

Furthermore, if the locking projection and one structure are integrally formed, the number of parts can be reduced and the manufacturing cost can be reduced as compared with the conventional case. Moreover, it is possible to suppress the movement direction guide portion and the guide portion and limited to only one is whether we controlled by, the manufacturing cost is simple and low mold for a sliding member of the slide member.

Furthermore, a fitting drive slope and a fitting passive slope are used when the pair of structures are fitted, and a disengagement drive slope and a separation passive slope when the pair of fitted structures are disengaged. Since the and are used, the slopes are selectively used depending on the fitting and the disengagement work. Thereby, the fitting work of the pair of structures can be reliably performed, and the fitting work of the pair of fitted structures can also be reliably performed.
