[Waterproof Inspection Method for Connector Housing] A waterproof inspection method for the female housing 8 using the waterproof inspection apparatus 1 according to the embodiment of the present invention will be described.

(1) In the case of the female housing 8 in which the rubber ring G is mounted in the proper position First, as shown in FIG. 5, the female housing 8 in which the rubber ring G is mounted in the proper position is mounted on the inspection table 20. When it is placed on the placing plate 23, the seating sensor 25 operates, the height detecting sensor S operates, and the inside direction of the step portion 64 of the contact body 6 protruding from the through hole 24 of the placing plate 23 is detected. The lower surface 65 contacts the rubber ring G, and the contact body 6 and the shields 70 and 71 descend due to the weight of the female housing 8. The shields 70, 71 that have descended have a gap 72 between the shields 70, 71.
Through the light emitting portion S1 of the height detection sensor S to the light receiving portion S
It moves to a position where the light beam emitted from 2 can be transmitted. Then, when the light beam emitted from the light emitting section S1 is received by the light receiving section S2, a non-defective item signal is transmitted from the light receiving section S1 to the control section 9, and further, the start signal transmitted from the control section 9 based on the non-defective item signal. The female housing 8 is printed by operating the printing unit 3 in response to the signal. After that, the printed female housing 8 is transferred to a subsequent process as a non-defective product, and the contact body 6 and the shields 70, 71 from which the female housing 8 is removed.
Is raised by the biasing force of the coil spring 53,
Return to the preset reference position. Furthermore, the seating sensor 2
5, it is detected that the female housing 8 has been removed, and the operation of the height detection sensor S ends.

(2) In the case of the female housing 8 in which the rubber ring G is not mounted at the proper position Next, when the rubber ring G is not mounted in the female housing 8 at all, as shown in FIG. Step 6 of contact body 6
The lower surface 65 of the inner portion 4 of the bearing 4 contacts the thick portion 84 of the step portion 83 formed on the outer periphery of the terminal accommodating chamber 82. At this time, the height of the lowered shields 70, 71 is higher than that of the case where the rubber ring G is mounted at the proper position.
The lower shield 71 reaches a height position where it blocks the light beam emitted from the light emitting portion S1 to the light receiving portion S2.
Therefore, since the non-defective product signal is not transmitted from the light receiving unit S2 to the control unit 9 and the printing unit 3 does not operate, it is determined that the female housing 8 is a defective product.

Further, when the rubber ring G is mounted inside the female housing 8 but is in a twisted state (see FIG. 7) or when it is inserted into the engagement groove 85 (see FIG. 8). ), Etc., the tip 63 of the protruding portion 62 of the abutting body 6 abuts the rubber ring G attached in an improper position when the female housing 8 is not attached at an appropriate position. At this time, the lowered height positions of the shields 70 and 71 are lowered by the height of the protrusion 62 as compared with the case where the rubber ring G is mounted at the proper position, and the upper shield 70 is moved from the light emitting portion S1. The height position is such that the light beam emitted to the light receiving portion S2 is blocked. Therefore, since the non-defective product signal is not transmitted from the light receiving unit S2 to the control unit 9 and the printing unit 3 does not operate, it is determined that the female housing 8 is a defective product. The female housing 8 determined to be a defective product is collected by being put in a defective product box (not shown) and processed so as not to be mixed with a non-defective product.

Therefore, in the waterproof inspection apparatus 1 according to the embodiment of the present invention, the contact member 6 is brought into contact with the rubber ring G, and the height position of the contact member 6 is detected by the discriminating means. Since the mounting state of the ring G can be determined, the waterproofness of the female housing 8 can be inspected quickly and reliably.

Further, in the waterproof inspection apparatus 1, the abutting body 6 is provided with the projecting portion 62, part of which is attached to the proper position due to the reason that the rubber ring G is twisted or the like, but the other portion. Is not attached to the proper position, the tip 63 of the protruding portion 62 first comes into contact with the rubber ring G. In such a case, when the contact body having no protruding portion is used, it may be determined that the rubber ring G is mounted at an appropriate position. Since such misidentification can be prevented, the waterproofness of the female housing 8 can be inspected more accurately.

Further, since the weight of the female housing 8 and the biasing force of the coil spring 53 are appropriately determined, the contact body 6 returns to the reference position by the upward biasing force of the coil spring 53 after the inspection. It will be. Therefore, when the waterproofness of the female housing 8 of the same type is continuously inspected, it is not necessary to adjust the position of the contact body 6 for each inspection, so that the waterproofness of the female housing 8 can be inspected more quickly. it can.

An example of the preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above embodiment, and design changes can be appropriately made without departing from the spirit of the present invention. For example, when the contact member 6 has the protrusion 62, it means that the rubber ring G is mounted at an improper position (in particular, the rubber ring G shown in FIG. 7 is twisted). However, even if the protrusion 62 is not necessarily provided, as shown in FIG. 9, the rubber ring in which the tip of the abutting body 6 is mounted at the normal position is provided. By contacting G, the same purpose can be achieved. Further, the shape such as the width and the length of the contact body 6 is not limited. Further, the waterproof inspection device 1 of the present invention can be applied to various female housings 8 by exchanging only the contact body 6 in accordance with the shape of the female housing 8. As for the shape of the female housing 8, as shown in FIG. 9, the step portion 83 is not formed on the outer periphery of the terminal housing chamber 82, and the rubber ring G is attached to the base end portion of the terminal housing chamber 82. You may have something.

Further, in the waterproof inspection apparatus 1 of the above-described embodiment, the contact body 6 is lowered against the biasing force of the coil spring 53 by the own weight of the female housing 8 (corresponding to the pressing force against the contact body 6). The configuration is shown. However, the structure may be such that the contact body is lowered by forcibly pressing the female housing 8 by manpower or mechanical means by increasing the biasing force of the coil spring.
