Abstract

Abstract Disclosed herein is a connector which comprises a female housing and a male housing to be inserted and fitted into the female housing for establishing electrical connection therebetween. A flexible locking arm having a locking aperture is provided on either the male or female housing, and a locking projection is provided on the other housing for generating a restoring force in the locking arm by cambering the locking arm when the male housing is inserted into the female housing. The locking projection engages with the locking aperture by the restoring force in the locking arm when the male and female housings are properly fitted together. The connector further comprises a member provided on the locking arm for producing a fitting-confirmation sound by the restoring force in the locking arm when the locking projection becomes engaged with the locking aperture. According to the connector of this invention, since the fitting-confirmation sound producing member is provided on the locking arm, the weight of the member increases the weight of the locking arm so as to enhance the restoring force. This makes it possible to obtain a larger fitting-confirmation sound than that of the conventional connector. In addition, the connector may include other members for producing fitting-confirmation sounds simultaneous with the production of the first fitting-confirmation sound, whereby it is possible to obtain two or more fitting-confirmation sounds when the male and female housings are properly fitted together.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 251 words
A connector, comprising: a female housing having an upper surface; a male housing to be inserted and fitted into said female housing for establishing electrical connection therebetween, the male housing having an upper surface; a flexible locking arm having a locking aperture, said locking arm provided on the upper surface of said male housing so as to be flexibly supported thereon, said flexible locking arm having a tip portion and two sides; a locking projection provided on the upper surface of said male housing, said locking projection generating a restoring force in said locking arm by cambering said locking arm when said male housing is inserted into said female housing, and said locking projection being engaged with said locking aperture by the restoring force when said male and female housings are properly fitted together; and means for producing a fitting-confirmation sound by said restoring force when said locking projection is engaged with said locking aperture, said fitting confirmation sound producing means comprising a pair of vertical plates provided on both sides of the tip portion of said locking arm, respectively, along the longitudinal direction of the locking arm in order to reinforce the tip portion of the locking arm, and the vertical plates being adapted to strike the upper surface of said female housing to produce the sound by the restoring force when said male and female housings are properly fitted, whereby the restoring force is generated only in the non-reinforced portion of said locking arm to increase the restoring force.
Claim 2
Dependent Claim 251 words
A connector, comprising: a female housing having an upper surface; a male housing to be inserted and fitted into said female housing for establishing electrical connection therebetween, the male housing having an upper surface; a flexible locking arm having a locking aperture, said locking arm provided on the upper surface of said male housing so as to be flexibly supported thereon, said flexible locking arm having a tip portion and two sides; a locking projection provided on the upper surface of said male housing, said locking projection generating a restoring force in said locking arm by cambering said locking arm when said male housing is inserted into said female housing, and said locking projection being engaged with said locking aperture by the restoring force when said male and female housings are properly fitted together; and means for producing a fitting-confirmation sound by said restoring force when said locking projection is engaged with said locking aperture, said fitting confirmation sound producing means comprising a pair of vertical plates provided on both sides of the tip portion of said locking arm, respectively, along the longitudinal direction of the locking arm in order to reinforce the tip portion of the locking arm, and the vertical plates being adapted to strike the upper surface of said female housing to produce the sound by the restoring force when said male and female housings are properly fitted, whereby the restoring force is generated only in the non-reinforced portion of said locking arm to increase the restoring force.
Claim 3
Dependent Claim 35 words
A connector as claimed in claim 1, wherein said female housing is formed from a material harder than that of said sound producing member so as to improve the tone quality of the fitting-confirmation sound.
Claim 4
Dependent Claim 21 words
A connector as claimed in claim 2, wherein said female housing is formed from a composition of vitreous material and PPS.
