Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fitting confirmation device for an electric connector used for connecting electric wiring of a vehicle.

[0002]

2. Description of the Related Art An electrical connector is for connecting female and male terminal fittings housed inside by fitting a pair of opposing connector housings. In order to secure the electrical connection, an electrical connector is provided between both housings. Locking means is provided to prevent the lock from coming off. Assembling and fitting work of the electrical connector depends on human labor, but since the number of connectors to be connected is extremely large, there is a possibility that unlocked products may be produced due to improper fitting. It is difficult to visually detect this in the subsequent inspection process, especially when using an electrical connector in a wiring system such as an air bag device, in terms of safety, incomplete fitting or unlocking is required. Is not allowed.

Therefore, Japanese Patent Laid-Open No. 3-49173 proposes a fitting confirmation device for an electrical connector as shown in FIGS. 21 (A) and 21 (B). In the figure, a is a male connector housing and b is a female connector housing, which is formed as a housing directly attached to a printed wiring board P in a case C such as an electric connection box. A hood c of the female housing b is provided with a lock lever e rotatably via a pressing spring d, and a lock plate f for holding the lever in a temporary lock position and a main lock position. Note that g is a short terminal and h is an L-type terminal, which is connected to the circuit conductor of the printed wiring board P.

The fitting confirmation of the female and male housings b and a is performed as follows. When the lock lever e is in the temporary lock position, the male housing a is inserted into the hood c of the female housing b, and when the lock housing is properly fitted, the lock lever e can be permanently locked by the lock plate f. In the case of halfway insertion, the engagement protrusion e ₁ on the rear surface of the lock lever e engages with the protrusion a ₁ of the male housing a and cannot be permanently locked, so that the quality of the fitting is confirmed.

[0005]

The device shown in FIG. 21 has the following problems. It is necessary to confirm the fitting. This is because after the fitting work of the female and male housings is completed, the lock lever e is rotated and the lock is fully locked to confirm the fitting. When used in case C, a clearance space is required on the case side. This is because the lock lever e is rotated between the temporary lock position and the main lock position, so that it is necessary to secure a space S that allows the rotation in the case. This is a kind of dead space. It is difficult to visually confirm whether or not the lock lever e is locked. This is because there is not much change in the states of the main lock and the temporary lock, and it is difficult for the operator to distinguish.

The present invention has been made in view of the above problems, and does not require a confirmation work other than the fitting work of the female and male connector housings and a large escape space when used in a case. Moreover, it is an object of the present invention to provide a fitting confirmation device for an electrical connector, which has a highly reliable electrical connection and which allows easy visual confirmation of fitting, thereby preventing incomplete fitting.

[0007]

In order to achieve the above-mentioned object, according to the present invention, a pair of connector housings to be fitted with each other, one of the connector housings is provided with one connector housing. , A slider for fitting confirmation is attached so that it can move in a direction intersecting with the fitting direction,
A means for urging the slider in a direction opposite to its moving direction is provided, an engaging portion is provided on one of the other connector housing and the slider, and a driven surface for engaging the engaging portion is provided on the other. A detent having is provided, and in the process of fitting the one connector housing and the other connector housing, the slider moves in the direction opposite to the urging direction due to the sliding contact between the engaging portion and the driven surface, As a result, a part of the slider projects or is exposed from the one connector housing, the sliding contact state between the engaging portion and the driven surface is released at the end of fitting, and the slider elastically returns to the original position. It is characterized by

[0008]

[Operation] If the pair of female and male connector housings are not completely fitted, the slider will partially project or be exposed. Therefore, incomplete fitting can be easily discriminated from the outside not only during the fitting work but also after the fitting work. That is,
The slider is completely accommodated in the slider accommodating chamber only when the two housings are completely fitted together, and at the same time, the locking between the two housings is achieved by the protrusion and the detent.

[0009]

1 to 4, A is a female connector housing made of synthetic resin, B is a male connector housing, and C is a male connector housing.
Indicates a case such as an electric junction box. The female housing A is formed as a direct-board-type female connector that is connected to a printed wiring board (not shown) built in a case C, as in the conventional example shown in FIG. In male housing B,
Inside, a plurality of terminal accommodating chambers 1 are arranged side by side vertically in two stages, a locking arm 2 having a locking protrusion 2a is provided outside, and a protrusion-shaped engaging portion 3 is provided upright. This engaging portion 3 drives the slider 14 and the female,
It has a function of confirming the fitting of the male housings A and B. The concave portion 4 is provided between the upper terminal accommodating chambers and the locking arm 2 is provided therein to prevent the arm 2 from being inadvertently bent by an external force.

The female housing A has a hood 5 in the front half thereof, and in the latter half thereof, L-shaped terminals h connected to the circuit conductors (not shown) of the printed wiring board in the case C are accommodated in parallel. ing. Hood 5 has a plurality of partition walls 6 inside, fitting chamber 7 _1, 7 _2, 7 ₃ and 7 ₄ are defined and formed with respect to another of the male housing in which the male housing B and not shown. On the inner surface of the upper part of the fitting chamber 7 ₁ , a pair of guide walls 8 and 8 for the concave portion 4 are provided so as to project.
Locking arm 2 in male housing B between
An engaging recess 9 (see FIG. 4) that engages with the engaging protrusion 2a is provided.

[0011] The upper wall of the hood 5 the slider accommodating chamber 10 across the fitting chamber 7 ₁ and 7 ₂ are formed bulging integrally, the slider 14 is in the slider accommodating chamber 10 is perpendicular to the housing fitting direction And a U-shaped spring 17 is mounted as a means for urging the slider 14 in the opposite direction to return it.

That is, the slider accommodating chamber 10 has an opening 11 for attaching and detaching the slider on the ceiling wall thereof, a window 12 for retracting the slider on the end wall side of the hood 5, and along the inner surface of the side wall in the longitudinal direction. A spring receiving groove 13 is provided. Both side edges of the opening 11 on the window 12 side are formed as tapered surfaces 11a having a width gradually narrowed.

The slider 14 is a rectangular plate, and a spring bearing 15 having a curved portion 15a is projectingly provided on one end thereof, and a detent 16 is projectingly provided on a lower surface thereof. The detent 16 constitutes a locking means for the male housing B together with the engaging portion 3 of the male housing B, and has a driven slope 16a having a downward slope in the drawing. The slider 14 is preferably colored differently from the female housing A. For example, if the female housing A is white, yellow, or green, it is black, red, brown, or the like that stands out.

The U-shaped spring 17 is made of an elastic strip material such as a piano wire, has elastic arms 17b extending from the bottom 17a to both sides and having a center curved outward, and a guide having its free end bent upward. It consists of a pin 17c.

In the above structure, the slider 14 is put into the slider accommodating chamber 10 through the opening 11, and U is inserted from above.
When both elastic arms 17b, 17b of the V-shaped spring 17 are set and released in a narrowed state, both elastic arms 17b, 17b expanded by elastic return are fitted into the spring receiving groove 13 respectively, and the U-shaped One bottom portion 17a of the spring 17 is supported by the spring receiver 15 of the slider 14, and the other guide pin 1
7c and 17c are tapered surfaces 11a in the opening 11,
It contacts the base end side of 11a. As a result, the slider 14
In the slider accommodating chamber 10, the U-shaped spring 17 prevents the floating and prevents the protrusion from the window 12.

Next, the operation of the slider 14 will be described with reference to FIGS. When the male housing B is inserted into the fitting chamber 7 ₁ of the female housing A as shown in (A), the tip of the engaging portion 3 is detented on the back surface of the slider 14.
When the slider 14 comes into contact with the driven slope 16a of No. 6 and is further pressed, the slider 14 moves in the direction of arrow M. As a result, the tip portion 14a of the slider 14 slightly projects from the window 12. At the same time, the U-shaped spring 17 whose bottom portion 17a is supported by the spring receiver 15 also moves in the direction of the arrow M, and the guide pin 17c at the tip of the elastic arm 17b slides on the tapered surface 11a, so that both elastic arms 17b and 17b move. The elastic repulsive force in the direction opposite to the arrow line M is narrowed.

When the male housing B is still inserted against the elastic repulsive force of the U-shaped spring 17 as shown in (B), the slider 14 moves further in the direction of arrow M, and the tip portion 14 thereof moves.
a protrudes greatly from the window 12, and a larger elastic repulsive force is accumulated in the U-shaped spring 17. The engaging part 3 is the detent 1
6 just before getting over the driven slope 16a, the slider 1
The amount of protrusion and the elastic repulsion of the tip portion 14a of No. 4 are maximum.

Then, as shown in (C), since the engaging portion 3 crosses over the driven slope 16a and the engagement between them is released, the slider 14 is released by the elastic repulsive force accumulated in the U-shaped spring 17. It momentarily moves in the direction opposite to arrow M. That is, the slider 14 is returned to its original position by completely inserting the female housing B into the fitting chamber 7 ₁ . as a result,
The detent 16 is located immediately after the engaging portion 3, and the male housing B is locked with the slider 14 (female housing A).
At the same time, since the locking protrusion 2a of the locking arm 2 engages with the locking recess 19 (see FIG. 4) of the female housing A,
The female and male housings A and B are doubly locked. To release the lock, push down the locking arm 2 and press the locking protrusion 2a.
And the engaging recess 9 are disengaged, and in this state the slider 1
4 can be performed by moving 4 in the direction of arrow M as in (B) above.

As described above, when the female and male housings A and B are fitted together, the tip portion 14a of the slider 14 projects from the window 12, so that the operator can visually check this at the same time as the fitting operation. If the coloring of the slider 14 is different from that of the female housing A as described above, the confirmation is easier. Thus, incomplete fitting of the female and male housings A and B is prevented in advance. Since the slider 14 only slightly reciprocates in parallel with the upper side wall of the hood 5 of the female housing B, it does not require a large space for mounting and can be compactly stored in the case C or the like.

In order to show the features of the present invention in brief,
The example in which the slider 14 projects from the window 12 by the male housing B fitted in the fitting chamber 7 _{1 of the} hood 5 has been described. Similarly, for the male housings fitted to the other fitting chambers 7 _{2 to} 7 ₄ as well, in order to make the slider 14 protrude, the slider housing chamber 10 is formed long so as to extend over each fitting chamber, and a plurality of sliders 14 are provided. It will be readily understood that the detents 16 in FIG.

6 (A) and 6 (B) show an application example of the fitting confirmation device using the slider 14 described above, in which the fitting work of the female and male housings A and B is recorded not only visually but automatically. In case of trouble, it is possible to easily pursue and confirm this from the recording paper. That is, FIG.
In (A), reference numeral 18 is a microswitch connected to a recorder (not shown), which has an insertion groove 20 on its side surface and is fitted into an insertion projection 21 provided on the end wall of the hood 5 in the female housing A. Fix together. Therefore, when the male housing B is completely fitted into the female housing A as described above, the tip portion 14a of the slider 14 protruding from the window 12 is contacted with the contact 1
By pressing 9, the complete fitting of the female and male housings A and B is confirmed not only visually by the operator but also electrically, and the fact is recorded and stored on the recording paper.

7 (A) and 7 (B) respectively show a second embodiment of the present invention. In this embodiment, the U-shaped spring 1 is used.
The elastic biasing means is formed on the slider itself without using 7. That is, the synthetic resin slider 14 'is
A pair of return elastic arms 23, 23 are formed at one end, and a detection arm 24 that elastically displaces in the housing fitting direction is provided at one side edge. The detection arm 24 has a free end for detection. A protrusion 24a is provided so as to project, and flexible locking claws 25, 25 are provided on both side edges. This slider 1
Corresponding to 4 ', the slider accommodating chamber 10' formed in the hood 5 does not have the window 12, and a detection window 22 is opened on the front wall of the accommodating chamber 10 '.

When the slider 14 'is inserted into the slider accommodating chamber 10' through the opening 11 ', the flexible locking claws 25 on both sides are engaged with the guide grooves 13' on the inner wall surface, and the housing is fitted in the same manner as the slider 14. The return elastic arms 23, 23 are movably locked orthogonally to the mating direction, and the tip ends of the elastic arms 23, 23 are tapered surfaces 11.
The protrusions 24a for detection of the detection arm 24 are located in the detection window 22 while being in contact with the base end portions of the a'and 11a ', and the operator can visually confirm this.

Then, as shown in FIG. 8A, when the male housing B is inserted into the hood 5, the engaging portion 3 thereof comes into contact with the driven slope 16a of the detent 16 on the rear surface of the slider 14 '. As shown in FIG. 8B, the male housing B is further added.
When is pressed, the slider 14 'moves in the direction of arrow M. At the same time, the elastic elastic arms 23, 23 for contacting the tapered surfaces 11a ', 11a' are narrowed and elastic elastic force is accumulated in the same manner as described above, the detection arm 24 bends backward and the detection projection 24a is detected. It disappears from the window 22. When the male housing B is completely fitted, the engaging portion 3 rides over the detent 16 and the slider 14 '.
Is returned to its original state by the elastic repulsive force accumulated in the return elastic arms 23, 23. As a result, the detection protrusion 24a of the detection arm 24 can be visually confirmed again through the detection window 22.

According to the second embodiment, since the male housing B is completely fitted, the slider 14 'itself returns elastically.
It is not necessary to use the U-shaped spring 14 as the biasing means as in the first embodiment, and the number of parts is reduced. Further, since the slider 14 'does not project to the outside from the slider accommodating chamber 10', when the female housing A is set in the case C as shown in FIG. It is effective when you cannot do it.

FIG. 9 and FIGS. 10A and 10B show a modified example of the first embodiment, in which confirmation of complete fitting can be made easier from the outside. The slider 14 ″ has the same basic structure as the slider 14, and a drive slope 26 is formed at its free end. 27 is the first slider 1.

Is inserted into the guide frame 29. As a result, the slider 27
The fixed portion 27b at the rear end is fixed by the locking piece 30, and the movable portion 27a reciprocates back and forth by the guide frame 29. Then, as shown in FIG. 10 (B), when the first slider 14 ″ projects from the window 12 by fitting the male housing B into the hood 5, the driving slope 26 of the first slider 14 ″ is driven.
8 is in sliding contact with the second slider 27 (the movable portion 27 of the second slider 27).
In a), the elastic elastic connecting piece 27c is pulled out to the front side as indicated by an arrow N against the tensile elasticity of the elastic connecting piece 27c. The maximum protrusion amount is when the male housing A is completely fitted as described above. When the slider 14 ″ is returned, the movable portion 27a is also instantaneously retracted to the original position by the elastic return force of the restoring elastic connecting piece 27c.

The slider 14 "and the slider 14,
Since 14 'is in a state of being built in the slider accommodating chamber when the male housing B is completely fitted, it may be difficult to visually confirm these by the position and viewing angle of the connector. However, in the example shown in FIGS. 9 and 10,
Since the second slider 27 is provided outside the hood 5, it is easy to confirm it from the outside even after the housing is fitted, and the presence of the second slider 27 allows the first slider 14 ″ to be detected. The existence of can be confirmed indirectly.
