Abstract

PROBLEM TO BE SOLVED: To easily hook fingers on to a finger hooking part, while preventing other members from being hooked. SOLUTION: A finger hooking part 14 is protrusively formed on the outer surface of a male housing 10, and a rib 15 linking to the finger hooking part 14 is also protrusively formed. Event if other members such as wires approach to the finger hooking part 14 along the outer surface of the male housing 10, they can settle without being hooked to the finger hooking part 14, since they would have to run on to the rib part 15 in order to be hooked. Since there is no fear that other members are hooked to the finger hooking part 14, fingers can be easily hooked by heightening the finger hooking part 14.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector.

[0002]

2. Description of the Related Art FIG. 11 shows a conventional connector. The connector includes a female housing a and a male housing b fitted so as to cover the female housing a with a hood c. From the rear surface of each of the housings a and b, an electric wire d is provided. Has been extended. In addition, a finger hook e is formed on the rear edge of the upper surface of the male housing b for hooking a finger when the two housings a and b are detached (see FIG. 12).

[0003]

In view of the ease with which a finger is hooked, it is desirable to increase the amount of protrusion of the finger hook e from the upper surface of the male housing b. However, on the other hand, when a large number of wire harnesses are accommodated in a transport / storage box (not shown) and only one wire harness is taken out of the box, if the finger hook e is high, the electric wire is There is also a situation in which d is caught on the finger hook e and becomes difficult to take out. The present invention has been made in view of the above circumstances, and has as its object to prevent a finger from being caught by a finger hook portion while preventing other members from being caught.

[0004]

According to a first aspect of the present invention, a finger hook portion is formed on at least one outer surface of a pair of housings which can be fitted and disengaged from each other, and when the two housings are disengaged from each other, the finger-holding portion is formed. In a connector in which a finger can be hooked on a finger hook portion, a rib connected to the finger hook portion is formed on an outer surface of the housing. The invention according to claim 2 is the connector according to claim 1, wherein a high area that is relatively higher than an area where the finger hook and the rib are formed is provided on an outer surface of the housing. The upper surface is configured to be flush with the high area.

[0005] The invention of claim 3 is claim 1 or claim 2.
In one aspect of the present invention, one or both of the finger hook and the rib are configured so that a drain portion is formed by partially notching. A fourth aspect of the present invention is characterized in that, in the third aspect of the invention, the water draining portion is configured to penetrate in the same direction as a mold opening direction of a mold for molding the housing.

[0006]

<Operation and effect of the invention><Invention of claim 1> Since a rib connected to the finger hook is formed on the outer surface of the housing, even if other members try to approach the finger hook while moving along the outer surface of the housing, there is no problem. Since the member rides on the rib, it does not need to be caught on the finger hook. As described above, since there is no possibility that another member is hooked on the finger hook, it is possible to make the finger hook high and to easily hook the finger.

<Invention of Claim 2> When another member moves to the rib side along the high area of the housing, the other member passes over the upper surface of the rib without being caught. <Invention of claim 3> Even if the liquid enters the area surrounded by the finger hook and the rib, the liquid is discharged to the outside through the drainage section. Therefore, it is possible to prevent the finger from slipping due to the liquid adhering to the finger hook. <Invention of Claim 4> Since the drainage portion is formed by opening the mold in the same direction as the mold for molding the housing, a so-called slide mold in which the mold opening direction is orthogonal to the mold for the housing is unnecessary, and The mold cost can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment A first embodiment of the present invention will be described below with reference to FIGS. The connector according to the present embodiment includes a pair of male and female housings 10 and 20 that can be fitted and disconnected from each other.
The male housing 10 has a rectangular cylindrical hood portion 12 into which a male terminal fitting (not shown) is inserted, and which protrudes forward. A tab of the male terminal fitting is provided in the hood portion 12. (Not shown) are projected.
Further, an electric wire 13 connected to the male terminal fitting extends from the rear end surface of the male housing 10. On the other hand, a female terminal fitting (not shown) is inserted into the female housing 20, and an electric wire 21 fixed to the female terminal fitting extends from the rear end surface of the female housing 20. The female housing 20 is fitted into the male housing 10 by being fitted into the hood portion 12, and is locked in the fitted state by locking means (not shown). When the operating portion (not shown) of the locking means is operated to release the lock, the two housings 10 and 20 can be detached. The detachment is performed using the finger hook 14 provided on the male housing 10.

The finger hook 14 is erected along the rear edge of the upper surface of the male housing 10. A thumb is hooked on the front edge of the finger hook 14, and an index finger is provided on the lower surface of the male housing 10. And the middle finger, the male housing 10 can be easily separated from the female housing 20. Such a male housing 1
A pair of ribs 15 are formed on the upper surface of 0 so as to extend along the left and right side edges. The pair of ribs 15 are the same height as the finger hooks 14, and the rear end of the rib 15 is the finger hook 1.
