JPH01175181A - Half-coupling preventing electric connector - Google Patents

Abstract

PURPOSE:To easily confirm the half-coupling by coating a fluorescent paint at the end of the coupling section of a male housing. CONSTITUTION:The preset display section 12 is provided at the end 11 of the coupling section of a male housing 1. A fluorescent paint is coated on the display section 12 with the preset width for easy identification. When this male housing 1 is inserted into a female housing 2, the display section 12 is not completely covered by the female housing 2 in the half-coupling state, part or all of it is exposed, thus the half-coupling state can be easily confirmed. The display section 12 of the male housing 1 is completely covered by the female housing 2 in the complete coupling state, thereby the complete coupling can be confirmed.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an electrical connector for use in automobile wire harnesses and the like to prevent half-fitting.

(B) Prior Art In conventional electrical connectors, a male housing and a female housing are fitted and locked together to mechanically connect electrical terminals housed in each housing. Conventionally, on an automobile assembly line, the fitting of connectors has been confirmed by the operator's touch or by the locking sound when the bottom metal is engaged.

(c) Problems to be solved by the present invention The problem to be solved by the present invention is that tactile fitting confirmation relies on the operator's senses, and the confirmation stability may decrease depending on the operator's skill level. In addition, it may be difficult to confirm the fitting by the locking sound depending on the working environment, and it is unstable, and it is difficult to reliably prevent the half-fitting state.

(d) Means for Solving the Problems The half-fitting prevention electrical connector of the present invention mechanically connects and locks a male housing and a female housing to mechanically connect electrical terminals housed in each housing. In the electrical connector, the above problem is solved by coating the end of the mating part of the male housing with fluorescent paint or forming a different light reflecting surface.

(E) Function In the electrical connector of the present invention, when the male housing is completely fitted into the female housing, the display section of the male housing is completely hidden inside the female housing. Complete mating can be confirmed.

If the display part of the male housing is showing even a little,
Since they are only half-fitted, the operator can easily check them.

(F) Embodiment An embodiment of the electrical connector based on the present invention will be described with reference to the drawings. First, as shown in FIG. 1, a predetermined display part 12 is provided in the fitting part path t@11 of the male housing 1.The 0 display part 12 is coated with fluorescent paint in a predetermined width for easy identification. formed by

As shown in FIG. 2, the display part 12 has a groove formed at the end 11 of the fitting part, but it may also be formed with a sloped surface, a pear-skinned surface, or the like to provide a reflective surface of different types of light.

FIG. 1 shows an embodiment in which a display portion 12 is provided on the upper surface 13 of the male housing 1 at the end 11 of the fitting portion excluding the lock lever 14.

On the other hand, FIG. 2 shows the upper surface 13 of the male housing 1 (lock
An embodiment in which a display section 12 is provided on the side surface 15 (excluding the lever 14) and the side surface 15 is shown.

Alternatively, the display section 12 may be provided along the entire circumference of the fitting section path t4A11 of the male housing 1, so that the display section 12 can be checked from any direction.

FIG. 3 is a side view of the electrical connector in a half-fitted state when the male housing 1 shown in FIG. 2 is inserted into the female housing 2. Figure 4 shows the male housing 1 shown in Figure 2.
2 is a side view of the electrical connector in a fitted state when inserted into the female housing 2. FIG.

In the half-fitted state shown in FIG.
Since it is not completely hidden inside and is partially or completely exposed, the operator can easily visually confirm the half-fitted state.

In the fitted state shown in FIG. 4, the display section 12 of the male housing 1 is completely hidden inside the female housing 2.
The operator can also confirm that they are in the fitted state.

(g) Effects According to the present invention, half-fitting can be easily and reliably confirmed by only slightly improving the existing electrical connector. especially,
When fluorescent paint is applied, it becomes easier to check even in the dark. Additionally, the dissimilar reflective surface portions can be formed simultaneously during primary processing, eliminating the need for secondary processing.
