[Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

(Description of overall connector configuration)
1A and 1B are diagrams showing a connector according to the present embodiment, where FIG. 1A is a plan view and FIG. 1B is a perspective view.

As shown in FIGS. 1A and 1B, the connector 1 includes a terminal block 2 and a connector 3.

The terminal block 2 is attached to a device such as a battery or an inverter, and has a first housing 5 on which a plate-like first electrode 4 (bus bar terminal) provided in the device is mounted. In the present embodiment, the case where the first electrode 4 is mounted on the device side will be described. However, the first electrode 4 may be provided integrally with the first housing 5. The first electrode 4 may be provided at the end of the cable.

The connector part 3 is provided at the end of the cable 6. The connector portion 3 includes a plate-like second electrode (bus bar terminal) 7 provided at the end of the cable 6 and a second housing 8 that accommodates the second electrode 7.

The connector 1 is configured such that when the first housing 5 of the terminal block 2 and the second housing 8 of the connector 3 are fitted, the first electrode 4 and the second electrode 7 are arranged to overlap each other. After the

housings

5 and 8 are fitted, the first electrode 4 and the second electrode 7 are electrically connected by fixing the first electrode 4 and the second electrode 7 with screws. It is configured as follows. That is, the connector 1 is a direct attachment type connector.

Here, a case will be described where two

electrodes

4, 7 and two cables 6 are provided, assuming a case where a DC power signal is transmitted, but the number of both

electrodes

4, 7 and cables 6 is this. It is not limited to.

Hereinafter, the detailed structure of each member will be described.

(Description of terminal block 2)
2 (a) and 2 (b) are perspective views of the terminal block 2, FIG. 3 (a) is a plan view thereof, FIG. 3 (b) is a front view thereof, and FIG. 3 (c) is a side view thereof. is there.

As shown in FIGS. 1 to 3, the first housing 5 of the terminal block 2 is formed in a hollow cylindrical shape, and is formed in a rectangular shape with rounded corners in a cross-sectional view. Hereinafter, the vertical direction in FIG. 2A is referred to as the height direction, the direction from the left front to the right back is referred to as the length direction, and the direction from the right front to the left back is referred to as the width direction.

The first housing 5 has two

side walls

5a and 5b that face each other in the width direction, and an upper wall 5c and a bottom wall 5d that connect the upper and lower ends of both

side walls

5a and 5b and face each other in the height direction. is doing. Both ends in the length direction of the first housing 5 are open, and the first electrode 4 is inserted from one opening and the connector portion 3 is inserted from the other opening.

A flange portion 10 that protrudes outward from the first housing 5 is formed at an end portion of the first housing 5 on the connector portion 3 insertion side. The flange portion 10 is made of, for example, metal, and the first housing 5 is made of, for example, resin.

The flange portion 10 has two bolt holes 10a for fixing the connector portion 3 with bolts, and six housing fixing holes 10b for fixing the terminal block portion 2 to a housing of a device (not shown). Is formed. The bolt holes 10a are respectively formed on the left and right sides in the width direction of the first housing so as to sandwich the opening of the first housing 5, and the housing fixing holes 10b are 4 of the flange portion 10 formed in a substantially rectangular shape. They are formed at the corners and at the center in the width direction at both ends in the height direction.

A seal member 11 that seals between the housing of the device and the flange portion 10 when the terminal block 2 is connected to the housing of the device is provided on the surface of the flange portion 10 opposite to the insertion side of the connector portion 3. It has been.

The base 12 on which the first electrode 4 is placed is integrally formed on the bottom wall 5d of the first housing 5 so as to protrude upward (inward) from the inner wall of the bottom wall 5d. The base 12 is provided with a fastening member 14 made of metal having a fastening hole 13 for fastening a screw for screwing.

The upper wall 5c above the fastening member 14 is formed with a notch 15 that opens to the insertion side of the first electrode 4, and a screw is inserted from the notch 15 to perform a screwing operation. Has been.

The base 12 is not formed at the end of the bottom wall 5d on the connector part 3 insertion side, and a step 16 is formed between the base 12 and the bottom wall 5d. The step 16 (the surface of the pedestal 12 on the side where the connector portion 3 is inserted) serves to push a terminal cover 30 described later into the second housing 8.

Moreover, the wall part 17 which protrudes upwards is formed in the both sides in the width direction of the base 12 and the center part in the width direction of the base 12. The wall portion 17 increases the role of a guide when the first electrode 4 is accommodated in the first housing 5 and the edge distance between the connecting portions of the first electrode 4 and the second electrode 7, thereby causing a problem such as a short circuit. It also plays a role in restraining.

A gap 19 is formed between the pedestal 12 and the

side walls

5a and 5b (between the wall 17 and the

side walls

5a and 5b). In the second housing 8, the tip end portion (projecting portion 35) of the inner housing 8 b is accommodated.

A plate-like locking release piece 18 is integrally formed on the wall portions 17 formed on both sides so as to protrude from the wall portion 17 to the insertion side of the connector portion 3. When the first housing 5 and the second housing 8 are fitted, the locking release piece 18 locks the terminal cover 30 by a locking means 37 (details will be described later) provided in the connector portion 3. It constitutes a lock releasing means for releasing.

A protruding portion 18a that protrudes outward in the width direction is integrally formed at the distal end portion (end portion on the insertion side of the connector portion 3) of the locking release piece 18. The protrusion 18a is used to push a lance 39, which will be described later, outward in the width direction, and is provided so as to be inclined so that the width becomes narrower toward the tip. Here, the protrusion 18a is formed in a trapezoidal shape when viewed from above.

The locking release piece 18 is formed in the first housing 5 so as not to protrude outward from the outer surface of the first housing 5. This is because the locking release piece 18 is formed in a thin plate shape, so that the mechanical strength is relatively low. If the locking release piece 18 protrudes from the first housing 5, there is an object in the protruding portion during connection work or the like. This is because the unlocking piece 18 may be damaged due to hitting.

Further, four pulling locking pieces 20 are integrally provided at the end of the first housing 5 on the connector part 3 insertion side. The drawer locking pieces 20 are provided so as to face each other in the height direction so as to sandwich a terminal cover 30 described later from above and below. The drawer locking piece 20 is formed in a rectangular frame shape, and latches a drawer projection 42 (described later) provided on the terminal cover 30 when the

housings

5 and 8 are fitted together. It is configured as follows. By locking the drawer locking piece 20 to the drawer protrusion 42, the terminal cover 30 is automatically pulled out from the second housing 8 when the fitting of the

housings

5 and 8 is released. ing.

Although details will be described later, in the present embodiment, when the pull-out locking piece 20 is locked to the pull-out protrusion 42, the pull-out lock piece 20 is deformed outward in the height direction so as to get over the pull-out protrusion 42. It is configured. Therefore, concave portions 21 are respectively formed in the upper wall 5c and the bottom wall 5d where the drawer locking pieces 20 are provided so that the drawer locking pieces 20 can be deformed outward. Further, a chamfering process is performed on the inner corner in the height direction on the front end side of the pull-out locking piece 20 so that the pull-out protrusion 42 can be easily climbed over. Since the drawer locking piece 20 is a member having a relatively low mechanical strength like the locking release piece 18, the drawer locking piece 20 does not protrude outward from the outer surface of the first housing 5 in order to prevent damage. The first housing 5 is formed.

Further, even when the terminal cover 30 is housed in the second housing 8, a part (front end portion) of the front in the fitting direction is arranged outside the second housing 8.

In addition, the connector portion 3 has a locking means 37 that locks the terminal cover 30 in a state of covering the second electrode 7 and restricts the terminal cover 30 from sliding into the second housing 8.

In the present embodiment, the locking means 37 is provided on the terminal housing 30 so as to protrude outward (in this case, on the side) and the second housing 8. The lance 39 includes a claw portion 39 a that is locked to the locking protrusion 38 in a state of covering the second electrode 7.

The locking protrusion 38 is formed at the end of the terminal cover 30 in the fitting direction and is formed so as to protrude laterally from the side surface of the terminal cover 30.

The claw portion 39a is provided so as to protrude inward in the width direction from the tip end portion (front end portion in the fitting direction) of the lance 39, and the terminal cover 30 is pulled out from the second housing 8 to be When the electrode 7 is covered with the terminal cover 30, the electrode 7 is locked to the locking protrusion 38 and is configured to restrict movement of the terminal cover 30 in the rearward direction of fitting.

Further, in the present embodiment, the claw portion 39 a is provided only at the upper portion at the tip portion of the lance 39, and the lower portion at the tip portion of the lance 39 is inclined inwardly away from the terminal cover 30 toward the tip. An unlocking slope 41 formed as described above is formed. The locking release slope 41 is formed by forming a notch in the lower part of the tip of the lance 39.

When the two

housings

5 and 8 are fitted together, the unlocking piece 18 (see FIG. 2B) abuts on the unlocking slope 41, and the second housing 8 is moved along the unlocking slope 41. It is pushed in. As a result, the lance 39 is pushed outward by the locking release piece 18 (projection 18a), the locking by the claw 39a is released, and the terminal cover 30 can be slid rearward in the fitting direction. In the connector 1, the unlocked terminal cover 30 is configured to be pushed into the second housing 8 and accommodated by the step 16 of the first housing 5.

The upper and lower surfaces of the tip portion of the terminal cover 30 are formed with protruding protrusions 42 protruding outward. When the

housings

5 and 8 are fitted together, the drawer protrusions 42 are locked to the drawer locking pieces 20 (see FIG. 2B), and when the

housings
