Abstract

The present invention relates to a connector device with a contact switch for electrical inspection which enables a connector position assurance member to be formed small and to electrically test whether the connector position assurance member is normally fastened. According to the present invention, since a second leg portion of the connector position assurance member moves along a sliding guide portion, the overall width of the connector position assurance member can be reduced. In addition, when the connector position assurance member is normally fastened to a first housing, the connector position assurance member presses first and second contact switches, and the first and second contact switches are elastically deformed and come in contact with each other to transmit an external signal. Therefore, an operator can electrically accurately inspect whether the connector position assurance member is normally fastened to the first housing.

Referring to (a) and (b) of Figure 11, when the forward pressure is applied to the head portion 304 after the leg coupling portion 302a is removed downwardly from the first engaging space portion 234a, the first The leg portion 302 is advanced along the locking space portion 219, and the leg coupling portion 302a passes through the second locking connection portion 236 and is hooked to the second locking space portion 236a. At this time, the first leg portion 302 is elastically deformed to its original position, and the leg coupling portion 302a is hooked to the second locking space portion 236a to become a normally fastened state (CPA secondary coupling state). And when the leg coupling portion 302a is engaged in the second engaging space portion 236a, the elastic lever 230 is in a state that cannot be moved downward, and the engaging portion 112a is the first engaging space portion 234a. ) is firmly maintained, so that the coupling between the first connector 100 and the second connector 200 is not arbitrarily released.

And when the first leg part 302 is advanced along the locking space part 219, the second leg part 306 is advanced along the sliding guide part 220. At this time, the second leg part 306 is the second leg part 306. By pressing the second contact portion 176 in the direction of the first contact portion 166 , the second inclined portion 174 is elastically deformed and comes into contact with the first contact portion 166 .

As such, when the connector position assurance member 300 is normally fastened to the first housing 110 , the connector position assurance member 300 presses the second inclined portion 174 toward the first contact portion 166 in the direction of the second inclination The portion 174 and the first contact portion 166 are in contact. And since the ON signal generated while the second inclined part 174 and the first contact part 166 are in contact is transmitted to the external board through the first coupling part 162 and the second coupling part 172, the operator can use the connector There is an effect of electrically accurately inspecting whether the position assurance member 300 is normally fastened to the first housing 110 .

Meanwhile, referring to FIG. 12 , the switch to provide a space in which the second inclined part 174 and the first contact part 166 can be accommodated on one side of the sliding guide part 220 opposite to the switch accommodating groove 112b. A receiving hole 220a is formed.

Accordingly, when the second leg portion 306 presses the second contact portion 176 in the direction of the first contact portion 166 , the second inclined portion 174 , the first contact portion 166 and the second contact portion 176 . is accommodated in the switch accommodating hole 220a, and the first inclined portion 164 is accommodated in the switch accommodating groove 112b. In this way, in the process of elastically deforming the second leg part 306 to be folded in the direction of the switch accommodating groove 112b, the switch accommodating hole 220a and the switch accommodating groove 112b form the first contact part 166, the second contact part ( 176 ) and the first inclined portion 164 are accommodated, so that the second contact portion 176 can be easily elastically deformed without collision or interference with surrounding components.

Although the present invention has been described in detail in the above embodiments, it is natural that the present invention is not limited thereto, and it is apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical spirit of the present invention. If it falls within the scope of the claims, the technical idea should also be regarded as belonging to the present invention.
