A pair of engaging projections 83 are provided on opposite sides of the pressing rib to deflect the lock arm 56 and engage the housing lock 58.

Next, the fitting operation of the male and female connectors having the above-described configuration will be described. First, the slider 60 shown in FIG. 10 is assembled. That is, when the slider 60 is assembled, one set of the compression springs 73 is attached to the spring accommodation chamber 7 in the second slide member 66.
After that, the stopper arm 63 of the first slide member 61 is inserted into the spring accommodating chamber 71. And
By engaging the engagement arm 68 with the stopper arm 63, the first slide member 61 and the second slide member 66 are integrated with the compression spring 73 held in the spring accommodating chamber 71.

Next, the slider 60 is attached to the male connector 50 from the front of the male connector 50 by the slider housing 5.
The slider 60 is pushed into the 3. At this time, the stopper arm 63 and the connecting portion 64 of the first slide member 61
And the side end portion of the second slide member 66 is fitted into the guide groove 55, and the rear end portion of the second slide member 66 abuts against the locking arm 57, thereby completing the mounting of the slider 60. In this state, the slider 60 is temporarily locked by the locking arm 57, but the compression spring 73 is not yet compressed. The description of the insertion of the contact into the terminal receiving chamber of the male connector 50 is omitted.

Next, the fitting operation of the male and female connectors 50 and 80 will be described. As shown in FIG. 11, the male connector 50 is moved from a state where the inner housing 52 of the male connector 50 and the housing insertion port 84 of the female connector 80 face each other.
The fitting operation of the male and female connectors is started so that the outer housing 51 of the female connector 80 is externally fitted to the housing 81 of the female connector 80. At this time, the pressing rib 82 of the female connector 80 is fitted into the insertion notch 67 a of the second slide member 66, and the front end of the pressing rib 82 contacts the contact portion 65 of the first slide member 61.

As the fitting operation proceeds, the pressing rib 82 of the female connector 80 is inserted into the insertion space 56a of the lock arm 56 of the male connector 50 while pushing the first slide member 61. At this time, the inclined surface of the housing lock 58 at the distal end of the lock arm 56 and the engaging projection 83 at the front end of the pressing rib 82 are in sliding contact with each other.
The distal end is displaced toward the housing 81 of the female connector 80. Therefore, the distal end portion of the housing lock 58 is engaged with the locking portion 67 of the second slide member 66, and the second slide member 66 cannot slide integrally with the first slide member 61.

When the fitting operation is further advanced, the first slide member 61 is moved backward by being pushed by the pressing rib 82. At this time, the slide groove 6 on the side of the first slide member 61
2 is allowed to move the engagement arm 68 of the second slide member 66. When the first slide member 61 moves while the second slide member 66 is stopped, the second slide member 61 moves.
The compression spring 73 in the slide member 66 is compressed, and a repulsive force that attempts to return to elasticity is generated. If the housing lock 58 on the male connector 50 side and the engagement projection 83 on the female connector 80 side are not fully engaged and the fitting operation is stopped, the compression spring 73 will re-engage. The first slide member 61 is pushed back in the detaching direction opposite to the joining direction. Thereby, the contact portion 65 of the first slide member 61
The female connector 80 is pushed back in the disengagement direction via the pressing rib 82 which has been in contact with the connector, and the halfway fitted state can be easily detected.

Then, when the fitting operation is advanced against the compression spring 73, the engagement projection 83 on the female connector 80 side goes over the housing lock 58 at the tip of the lock arm 56 and is elastically restored. Thereby, as shown in FIG. 10, the engagement state between the distal end portion of the housing lock 58 and the locking portion 67 at the distal end of the second slide member 66 is released, and the housing lock 58 is engaged with the rear end of the engagement projection 83. Is done. Therefore, the male connector 50 and the female connector 80 are in a completely fitted state, and the contacts 54 and 85 are also in a completely electrically connected state.

At this time, the housing lock 58 and the locking portion 6
7 is released, the compression force acting on the compression spring 73 is released, and the resilient force of the compression spring 73 causes the second sliding member 66 to bend. It is moved backward over the locking force and pushed back to its original position relative to the first slide member 61. that time,
The operation unit 6 covering the pressing unit 59 on the lock arm 56
As 9 moves rearward, the pressing portion 59 is exposed upward. Further, the locking arm 67 of the second slide member 66 moves into the bending space at the distal end portion of the lock arm 56, so that the lock arm 56 is locked in an inflexible state. Therefore, the complete fitting state of the male connector 50 and the female connector 80 can be easily detected by the exposure of the pressing portion 59 together with the sense of moderation when the housing lock 58 and the engaging projection 83 are engaged.

[0017]

However, the conventional half-fitting prevention connector has the following problems when the slider 60 is mounted in the terminal accommodating chamber 53. That is,
The first slide member 61 constituting the slider 60 is not locked by the housing 51, in other words, by the slider housing 53, and the compression spring 73 does not bias the first slide member 61. For this reason, a clearance between the first slide member 61 and the other members, in other words, a dimensional play, occurs, which causes abnormal noise. In order to prevent the generation of the abnormal noise, the compression spring 73 is used.
When the first slide member 61 is urged, there is a problem that the first slide member 61 protrudes from the front end of the housing 51.

An object of the present invention has been made in view of the above problems, and a connector fitting structure in which a slider is mounted without looseness in a slider accommodating chamber provided in one of a pair of male and female connectors. It is to provide.

[0019]

And a pair of compression springs 23 as elastic members that are held inside the second slide member 22 in an extended state, and exert an elastic force in a direction to separate the first and second slide members 21 and 22 from each other. ing.

The first slide member 21 includes a pair of stopper arms 24 extending rearward and abutting against one end of a compression spring 23, and a connecting portion 25 connecting the stopper arms 24 at a front end. A pressing rib 2 formed on a female connector 3 described below is provided below a front end of the connecting portion.
6 (see FIG. 1) is provided with a contact portion 27 with which the contact member 6 contacts. On the upper part of the stopper arm 24, a locking auxiliary surface 24a for locking a locking auxiliary arm 28 described later is provided.
Is provided.

Further, a pair of the stopper arms 24,
A pair of locking projections 45, 45 are provided outside the 24. When the male and female connectors are fitted together, the first and second slide members 21 and 22 approach each other.
At the time of this approach, a slide groove 29 for releasing a second locking portion 16 a provided at the tip of the first engagement arm 16 described later is provided at the rear end of the connecting portion 25.

The second slide member 22 has a locking portion 31 extending downward at a lower front end thereof for suppressing the downward displacement of the lock arm 8, and an operating portion 32 at the upper center for operating when releasing the fitting. A flexible engagement arm 33 (see FIG. 1) is provided below the operation section 32. The engagement arm 33 engages with the pressing portion 8b to prevent the slider 4 from coming out when the slider 4 is mounted on the outer housing 5, and is provided with an engagement projection 33a at a lower end portion. .

A notch 31a is formed between the pair of locking portions 31, 31 so that the pressing rib 26 formed on the female connector 3 does not interfere with each other when the male and female connectors 2, 3 are fitted. An inclined surface 31b having a predetermined angle is formed on the inner surface of each of the locking portions 31, 31. Further, a flexible locking assist arm 28 is provided on the second slide member 22, and a locking assist projection 28 a locked on the locking assist surface 24 a of the first slide member 21 is provided at a lower front end thereof. Is formed.

As shown in FIG. 1, a housing 34 constituting the female connector 3 as the other connector includes:
The pin contact 35 protrudes in the fitting direction, that is, in the direction of arrow A, and the above-described first center
Pressing rib 2 abutting on contact portion 27 of slide member 21
6 extend in the fitting direction. Further, a pair of engaging protrusions 36 are provided on both sides of the pressing rib 26 facing the distal end side, and when the female and male connectors 2 and 3 are fitted to each other, the lock arm 8 is bent and the housing lock 8a is provided. Is adapted to be engaged.

Next, the assembly of the slider 4 will be described. As shown by an arrow a in FIG. 2, the slider 4 is assembled by inserting a compression spring 23 into fitting grooves 41 formed on both sides of the second slide member 22, and projecting at the tip of the fitting groove 41. One end of the compression spring 23 is inserted into and engaged with the provided engagement projection 42. Next, as shown by an arrow b in FIG. 2, the first slide member 21 is moved closer to the open end side of the second slide member 22, and the other end of the compression spring 23 is inserted through the engagement protrusion 43. , And are inserted further so as to be sandwiched between the fitting groove 41 and the auxiliary arm 28.
Then, the auxiliary arm 28 is bent and deformed upward, and elastically returns to the original shape when the locking auxiliary projection 28a is locked to the locking auxiliary surface 24a, and the first and second slide members 21 and 22 are returned.
And the compression spring 23 are integrally assembled, and the slide 4
Is completed.

Next, the assembly of the slider 4 to the male connector 2 will be described. The slider 4 has an arrow A in FIG.
As shown in the figure, the male connector 2 is inserted into the slider accommodating portion 11 formed on the upper portion. At the time of insertion, the operating portion 32 slides in a state of being deformed downward by contacting the upper inner surface of the outer housing 5, that is, the first locking portion 15 shown in FIG. When it reaches the formed side space 11a,
It elastically returns to its original shape. Therefore, the slider 4
Is properly inserted, in other words, whether assembly is appropriate or not can be confirmed by the return of the shape of the operation unit 32. When the slider 4 is completely mounted in the slider accommodating portion 11, the entire slider 4 is buried in the outer housing 5 constituting the male connector 2 as shown in FIG. The part 25 and the like are exposed.

In the present embodiment, when the slider 4 is assembled to the male connector 2, the following notable locking is performed. That is, as shown in FIG.
1 is provided with a locking projection 45, and a pair of slider locking portions 46, 46 is provided on the front end side of the terminal accommodating chamber 11 as shown in a partially cut-away portion in FIG. 1. Therefore, when assembling the slider 4 to the male connector 2, the resistance temporarily increases when the pair of locking projections 45, 45 contact the pair of slider locking portions 46, 46. Then, the pair of locking projections 45, 45 are pushed into the housing 5 by elastic deformation of the housing 5 and the like, so that the pair of slider locking portions 46,
Get over 46. As a result, as shown in FIG.
45 is locked by the pair of slider locking portions 46, 46, and a click sensation occurs when the user gets over the slider. Therefore, it can be recognized that the slider 4 has been securely assembled to the male connector 2 by the return of the shape of the operation portion 32 and the click feeling.

When the slider 4 is assembled to the male connector 2, as shown in FIG.
Since the engagement arm 16 is engaged, the entire slider 4 does not move rearward as it is. On the other hand, the compression spring 23 urges the entire first slide member 21 by a repulsive force with the rear end of the second slide member 22 as a fulcrum. However, since the locking auxiliary projection 28a is locked to the locking auxiliary surface 24a, the width of elastically swinging in the axial direction by the urging of the first slide member 21 is small. Then, the first slide member 21 is urged by the repulsive force of the compression spring 23 by locking the pair of locking protrusions 45, 45 to the pair of slider locking portions 46, 46 as in the present embodiment. At this time, as shown in FIG.
5, 45 are pressed against the pair of slider locking portions 46, 46, and no gap is formed, so that generation of abnormal noise due to rattling can be prevented.

Next, the operation of fitting the male and female connectors 2 and 3 will be described. The female connector 3 is fitted to the male connector 2 from the direction of arrow A shown in FIG. 1, and the engagement protrusion 36 comes into contact with the contact portion 27 by inserting the female connector 3 into the male connector 2. Then, when the female connector 3 is further pushed in, the first slide member 21 is elastically supported by the compression spring 33, so that the first slide member 21 is pushed in by the female connector 3 as shown in FIG. 11 is pushed. Then, the engagement protrusion 36 rides up from the tapered surface formed at the front end of the housing lock 8a, and the entire lock arm 8 is flexed and deformed in accordance with the amount of pushing of the female connector 3. In addition, pin contact 3
5 is inserted into the socket contact 6.

Next, when the female connector 3 is further pushed into the male connector 2 from the state shown in FIG. 6, the upper end of the connecting portion 25 is brought into a second engagement position as shown in FIG. Since the second engaging portion 16a escapes into the slide groove 29 because it rides on the tapered surface of the stop portion 16a, the front end of the first engaging arm 16 also bends downward and deforms. As a result, the second locking portion 16a comes off from the first locking portion 15. At this time, the engaging projection 36 rides on the housing lock 8a and tries to get over it. Further, the pin contact 35 is inserted deeper into the socket contact 6.

Further, when the female connector 3 is pushed into the male connector 2 from the state shown in FIG. 7, the engagement projection 36 gets over the housing lock 8a, and the lock arm 8 returns to its original shape by its own elasticity. The engagement projection 36
And the housing lock 8a are engaged. In addition, since the engagement between the first locking portion 15 and the second locking portion 16a is completely released, the whole of the slider 4 is moved deep inside the slider accommodating portion 11 by the repulsive force of the compression spring 23 (rightward in the drawing). ).
In this state, the male and female connectors 2 and 3 are completely fitted, and the male and female connectors 2 and 3 cannot be disengaged by the engagement between the engagement protrusion 36 and the housing lock 8a. Then, the pin contact 35 is inserted into the socket contact 6 to be in an electrically connected state. Further, since the housing 34 of the female connector 3 is pressed against the seal member 14, the female and male connectors 2 and 3 cannot be pulled out and are in a watertight fitting state. An electric wire 37 is connected to the socket contact 6 by caulking or the like, and a waterproof plug 38 is provided between the electric wire 37 and the outer housing 5. Therefore, the electric wire 37
Infiltration of water or the like transmitted from the water is prevented by the waterproof plug 38.

As described above, when the male and female connectors 2 and 3 are completely fitted, the second slide member 22 is shown in FIG. 8 by the repulsive force of the compression spring 23 with the first slide member 21 of the slider 4 as a fulcrum. Is elastically pressed against the wall of the slider housing 11. On the other hand, a curved surface R is formed at the upper end of the side space 11a for cutting off the mold and improving the strength.
Therefore, if the upper end portion 32a of the base of the operation portion 32 is formed in a rectangular shape, the upper end portion 32a strongly contacts the position of the curved surface R, and cracks or chips may occur on both or any one of them. It is sufficient if the cracks and chips can be detected at the manufacturing stage, but it is difficult to detect them from the position. Therefore, in the present embodiment, the upper end portion is configured to be the tapered surface 32a so as not to abut on the curved surface R. According to this configuration, even if the second slide member 22 slides to the rear end side due to the repulsive force of the compression spring 33, neither the operation portion 32 nor the curved surface R is cracked or chipped, and the male and female connectors 2 3, the reliability is improved.

Next, the release of the fitting of the male and female connectors 2 and 3 will be described. In the case of disengagement of the male and female connectors 2 and 3, the operation unit 32 is pushed in the direction of arrow B as shown in FIG. As a result, the second locking portion 16a formed at the tip of the first engagement arm 16 passes over the first locking portion 15 from the position shown in FIG. 8 as shown in FIG. At this time, since the second locking portion 16a descends while sliding on the lower surface of the first locking portion 15, inclined surfaces 15a, 16b are provided at the front end of the second locking portion 16a and the lower end of the first locking portion 15. Is formed, the second locking portion 16a can get over the first locking portion 15 along the inclined surface only by pulling the operation portion 32 in the direction of arrow B. Therefore, the inclined surfaces 15a and 16b have a guiding function, and the downward pushing operation described in the conventional example becomes unnecessary, so that the operability is improved.

The second locking portion 16a is connected to the first locking portion 1
When the first slide member 21 has completely passed over the first slide member 5, the first slide member 21 is pushed by the repulsive force of the compression spring 23, and the disengagement can be smoothly performed. Also, the second locking portion 16
When “a” has completely passed over the first locking portion 15, the end of the operating portion 32 contacts the end of the first locking portion 15, in other words, one end of the housing 5 in which the first locking portion 15 is formed. contact,
Movement in the direction of arrow B is prevented. Therefore, when the fitting is released, the contact can detect the fitting release, and the operability at the time of releasing the fitting is improved.

As described above, the connector fitting structure according to the present embodiment has the first structure when the slider is mounted on the housing.
Since the pair of locking projections 45, 45 provided on the slide member are locked by the pair of slider locking portions 46, 46 provided on the housing 5, no clearance is formed between the slider 4 and the housing 5, Generation of abnormal noise and the like can be prevented.

[0042]

As described above, according to the connector fitting structure of the present invention, the slider engaging portion for preventing the slider from coming off is provided on the inner surface of the slider accommodating portion.
A locking projection is provided on a side portion of the first slide member to be locked to the slider locking portion. When the slider is mounted in the slider accommodating portion, the locking projection is locked to the slider locking portion, so that the slider of the slider is provided. Prevents escape from the storage section. Therefore, when the slider is mounted in the slider housing chamber provided in the housing, the locking projection provided on the first slide member is locked on the slider locking portion provided on the slider housing chamber, and the first slide member is compressed by the spring. Is biased, so that the locking projection comes into pressure contact with the slider locking portion,
Generation of abnormal noise and the like and escape from the slider accommodating chamber can be reliably prevented.
