Detailed Description

Hereinafter, a connector 1 and a connector unit 100 including the connector 1 according to the embodiment of the present invention will be described with reference to fig. 1 to 15. For easy understanding, XYZ coordinates orthogonal to each other are set and appropriately referred to. As shown in fig. 1, the Y-axis direction of the XYZ coordinates is the same direction in the connector 1 as the 1 st direction D1 in which the terminal 30 is inserted into the housing main body 10. The X-axis direction is the same direction as the 2 nd direction D2 in which the stopper 20 is inserted into the stopper insertion port 13 of the case main body 10. The Z-axis direction is a direction orthogonal to both the 1 st direction D1 and the 2 nd direction D2.

The connector unit 100 is, for example, an in-vehicle connector as an automobile component. The connector unit 100 includes a connector 1 and a counterpart connector 200 fitted to the connector 1.

The gap 55 also has an effect of pulling the stopper 20 pushed to the 2 nd position back to the 1 st position before the stopper is pushed by inserting the tip end of the tool or jig along the inclined surface 55a and engaging the tip end with the stopper 20 by the inclined surface 55 a.

In the wall portion 50 configured as described above, the 1 st to 4 th wall portions 51 to 54 are all formed to have the same height. As can be seen from fig. 8A and 9A, the 1 st to 4 th wall portions 51 to 54 project to the same positions as the position H of the pressing surface P when the stopper 20 is disposed at the 1 st position (before the stopper is pushed in).

As described above, in the present embodiment, as shown in fig. 13, the wall portion 50 is formed around the stopper insertion port 13. Therefore, even when an unexpected force is applied to the case main body 10 from the outside before the assembly of the connector 1 is completed, for example, when parts of the connector 1 are carried, the wall portion 50 protects the stopper 20 and suppresses the pushing-in of the stopper 20 due to the unexpected force. As a result, the work efficiency of assembling the connector 1 can be improved.

In the present embodiment, as shown in fig. 9A, 9B, 10A, 10B, and 10C, the wall portion 50 protrudes to the same position as the position H of the pressing surface P when the stopper 20 is disposed at the 1 st position. On the other hand, for example, in the case where the wall portion 50 is higher than the position H of the pressing surface P at the 1 st position, it is difficult for the user to push the stopper 20 when the operation of assembling the connector 1 is performed. Further, in the case where the wall portion 50 is lower than the position H of the pressing surface P of the 1 st position, it is difficult for the wall portion 50 to suppress the pushing-in of the stopper 20 by an unexpected force. Therefore, the work efficiency of assembling the connector 1 may be lowered regardless of whether the position H of the pressing surface P at the 1 st position of the wall portion 50 is lower or higher. In contrast, in the present embodiment, the wall portion 50 does not hinder the pushing-in operation of the stopper 20 by the user at the time of the operation of assembling the connector 1, and the wall portion 50 can suppress the pushing-in of the stopper 20 by an unexpected force. As a result, the work efficiency of assembling the connector 1 can be improved.

Further, in the present embodiment, as shown in fig. 13, a notch 51a is formed in the 1 st wall portion 51, and a gap 55 is formed between the 3 rd wall portion 53 and the 4 th wall portion 54. The notch 51a and the gap 55 are both provided on the line of a straight line L1 parallel to the Y-axis direction. Generally, a user often places a finger along the line L1 and pushes the stopper 20 in during the assembly operation. Therefore, the wall portion 50 does not hinder the pushing-in operation of the stopper 20 by the user by forming the notch 51a and the gap 55, and the wall portion 50 can suppress the pushing-in of the stopper 20 by an unexpected force. As a result, the work efficiency of assembling the connector 1 can be improved.

In the present embodiment, a 3 rd wall portion 53 is formed around the 1 st arm passage opening 13b protruding from the + Z side end portion of the insertion port body 13 a. Since the area S2 of the 1 st arm passage opening 13b is formed smaller than the area S1 of the insertion opening main body 13a, even in the case where an unexpected force is applied to the case main body 10 with a relatively large force, the 3 rd wall portion 53 around the 1 st arm passage opening 13b can effectively suppress the pushing-in of the stopper 20 caused by the force. As a result, the work efficiency of assembling the connector 1 can be improved.

In the present embodiment, the 4 th wall portion 54 is also formed around the 2 nd arm passage opening 13c protruding from the-Z-side end portion of the insertion opening body 13 a. Since the area S3 of the 2 nd arm passage opening 13c is formed smaller than the area S1 of the insertion opening main body 13a, the 4 th wall portion 54 around the 2 nd arm passage opening 13c can effectively suppress the pushing-in of the stopper 20 caused by an unexpected force even in the case where the unexpected force applied to the case main body 10 is large. As a result, the work efficiency of assembling the connector 1 can be improved.

The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments.

For example, in the above embodiment, as shown in fig. 13, the wall portion 50 has a pair of 2 nd wall portions 52, 3 rd wall portions 53, and 4 th wall portions 54 in addition to the 1 st wall portion 51. But is not limited thereto. The wall portion 50 may have at least the 1 st wall portion 51. For example, the wall portion 50 may not have the 2 nd wall portion 52 like the connector 1A of the modification 1 shown in fig. 16.

Further, in the above embodiment, as shown in fig. 13, the wall portion 50 has only one 1 st wall portion 51 provided along the 3 rd direction D3 (Z-axis direction). But is not limited thereto. The wall portion 50 may also be provided with a 1 st wall portion 51 so as to have a plurality of 1 st wall portions 51 in the vicinity of the edge on the + Y side of the stopper insertion port 13, like the connector 1B of modification 2 shown in fig. 17. In this case, the notch 51a does not need to be formed in all of the 1 st wall portion 51.

In the above embodiment, as shown in fig. 13, the wall portion 50 has the 1 st wall portion 51, the pair of 2 nd wall portions 52, the 3 rd wall portion 53, and the 4 th wall portion 54, and is formed so as to cover substantially the entire circumference of the side surface of the stopper 20 located at the 1 st position. But is not limited thereto. For example, like the connector 1C of modification 3 shown in fig. 18, the wall portion 50 may not have the 1 st wall portion 51 and the 2 nd wall portion 52 but may have the 3 rd wall portion 53 or the 4 th wall portion 54. In this case, since the 3 rd wall section 53 has the base end side wall section 53-1 provided along the 3 rd direction D3 and the 4 th wall section 54 has the base end side wall section 54-1 provided along the 3 rd direction D3, the base end side wall sections 53-1, 54-1 correspond to the "1 st wall section" of the claims.

Further, in modification 3 described above, the 3 rd wall portion 53 has the inner side wall portion 53-3 in addition to the base end side wall portion 53-1, and the 4 th wall portion 54 has the inner side wall portion 54-3 in addition to the base end side wall portion 54-1. But is not limited thereto. For example, as in the connector 1D of modification 4 shown in fig. 19, the 3 rd wall portion 53 may not have the inner side wall portion 53-3 as long as it has the base end side wall portion 53-1 corresponding to the "1 st wall portion" in the claims, and the 4 th wall portion 54 may not have the inner side wall portion 54-3 as long as it has the base end side wall portion 54-1 corresponding to the "1 st wall portion" in the claims. In modification 4, the 3 rd wall portion 53 has an outer side wall portion 53-2 provided along the 1 st direction D1, and the 4 th wall portion 54 has an outer side wall portion 54-2 provided along the 1 st direction D1, and the outer side wall portions 53-2 and 54-2 correspond to the "2 nd wall portion" in the claims.

Further, in modification 3 described above, the 3 rd wall section 53 has the outer side wall section 53-2 in addition to the base end side wall section 53-1, and the 4 th wall section 54 has the outer side wall section 54-2 in addition to the base end side wall section 54-1. But is not limited thereto. For example, like the connector 1E of modification 5 shown in fig. 20, the 3 rd wall part 53 may not have the outer side wall part 53-2 as long as it has the base end side wall part 53-1 corresponding to the "1 st wall part" in the claims, and the 4 th wall part 54 may not have the outer side wall part 54-2 as long as it has the base end side wall part 54-1 corresponding to the "1 st wall part" in the claims. In modification 5, the 3 rd wall portion 53 has an inner side wall portion 53-3 provided along the 1 st direction D1, and the 4 th wall portion 54 has an inner side wall portion 54-3 provided along the 1 st direction D1, and the inner side wall portions 53-3, 54-3 correspond to the "2 nd wall portion" in the claims.

In the above modifications 4 and 5, the 3 rd wall portion 53 has the outer side wall portion 53-2 or the inner side wall portion 53-3 corresponding to the "2 nd wall portion" in the claims, and the 4 th wall portion 54 has the outer side wall portion 54-2 or the inner side wall portion 54-3 corresponding to the "2 nd wall portion" in the claims. But is not limited thereto. For example, as in the connector 1F of modification 6 shown in fig. 21, the 3 rd wall portion 53 may not have both the outer side wall portion 53-2 and the inner side wall portion 53-3 as long as it has a base end side wall portion 53-1 corresponding to the "1 st wall portion" in the claims, and the 4 th wall portion 54 may not have both the outer side wall portion 54-2 and the inner side wall portion 54-3 as long as it has a base end side wall portion 54-1 corresponding to the "1 st wall portion" in the claims.

In the above embodiment, as shown in fig. 13, the 3 rd wall portion 53 is formed by the base end side wall portion 53-1 provided along the 3 rd direction D3 and the outer side wall portion 53-2 and the inner side wall portion 53-3 provided along the 1 st direction D1. Likewise, the 4 th wall portion 54 is formed by the base end side wall portion 54-1 provided along the 3 rd direction D3 and the outer side wall portion 54-2 and the inner side wall portion 54-3 provided along the 1 st direction D1. That is, the 3 rd wall portion 53 and the 4 th wall portion 54 are each formed of wall portions disposed along the 1 st direction D1 and the 3 rd direction D3. Therefore, in the above embodiment, it can be said that the "1 st wall portion" of the claims corresponds to the 1 st wall portion 51 and the base end side wall portions 53-1, 54-1. In the above embodiment, the "2 nd wall portion" in the claims may be said to correspond to the 2 nd wall portion 52, the outer side wall portions 53-2 and 54-2, and the inner side wall portions 53-3 and 54-3. Thus, in the above embodiment, it can also be said that the wall portion 50 does not have the "3 rd wall portion" and the "4 th wall portion" of the claims. In contrast, in the case where the 3 rd wall portion 53 and the 4 th wall portion 54 have wall portions other than the wall portions provided along the 1 st direction D1 and the 3 rd direction D3, for example, curved wall portions like the connector 1G of modification 7 shown in fig. 22, the wall portion 50 can be said to have the "3 rd wall portion" and the "4 th wall portion" of the claims.

Further, in the above embodiment, the 3 rd wall portion 53 is formed in the range of substantially the entire circumference around the 1 st arm passage opening 13b, and the 4 th wall portion 54 is formed in the range of substantially the entire circumference around the 2 nd arm passage opening 13 c. But is not limited thereto. The claims "the 3 rd wall portion is formed around the 1 st arm passage opening" and "the 4 th wall portion is formed around the 2 nd arm passage opening" include, for example, a case where the 3 rd wall portion 53 is formed locally around the 1 st arm passage opening 13b and the 4 th wall portion 54 is formed locally around the 2 nd arm passage opening 13c, like the connector 1H of the modification 8 shown in fig. 23.

Further, in the above-described embodiment and modifications 1 to 8, the wall portion 50 has both the 3 rd wall portion 53 and the 4 th wall portion 54. But is not limited thereto, the wall portion 50 may have only either one of the 3 rd wall portion 53 and the 4 th wall portion 54.

The present invention is capable of various embodiments and modifications without departing from the broad spirit and scope of the invention. The above embodiments are merely illustrative of the present invention and do not limit the scope of the present invention.
