Abstract
Abstract A short-circuit contact is doubly locked by providing a locking protrusion at a cover plate of the short-circuit contact mounted on one connector housing, engaging the locking protrusion with a locking recess provided at a contact-support chamber of the one connector housing to primarily lock the short-circuit contact, engaging the insert locking piece into a locking piece insertion hole provided at the one connector housing to engage a locking protrusion of the insert locking piece with the base plate of the short-circuit contact, thereby secondarily locking the short-circuit contact.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
A locking structure for doubly locking a short-circuit contact which forms a part of a connection sensor of an electrical connector having a pair of electrical connector housings comprising: said short-circuit contact having elastic contact pieces and a base plate, said base plate primarily locked to one connector housing of said pair of electrical connector housings by locking means; a pair of connection sensing terminals mounted in the other connector housing of said pair of connector housings engaging with said elastic contact pieces of said short-circuit contact when said pair of electrical connector housings are completely engaged; said one connector housing of said pair of connector housings further comprising a contact support chamber to receive said short-circuit contact and a wall including a locking piece insertion hole; and an insert locking piece having a locking protrusion for secondarily locking said short-circuit contact, when said insert locking piece is inserted into said locking piece insertion hole, whereby said base plate of said short-circuit contact is contacted with said locking protrusion of said insert locking piece to lock said short-circuit contact to said contact-support member.
Claim 2
Dependent Claim
183 words
A locking structure for doubly locking a short-circuit contact which forms a part of a connection sensor of an electrical connector having a pair of electrical connector housings comprising: said short-circuit contact having elastic contact pieces and a base plate, said base plate primarily locked to one connector housing of said pair of electrical connector housings by locking means; a pair of connection sensing terminals mounted in the other connector housing of said pair of connector housings engaging with said elastic contact pieces of said short-circuit contact when said pair of electrical connector housings are completely engaged; said one connector housing of said pair of connector housings further comprising a contact support chamber to receive said short-circuit contact and a wall including a locking piece insertion hole; and an insert locking piece having a locking protrusion for secondarily locking said short-circuit contact, when said insert locking piece is inserted into said locking piece insertion hole, whereby said base plate of said short-circuit contact is contacted with said locking protrusion of said insert locking piece to lock said short-circuit contact to said contact-support member.
Claim 3
Dependent Claim
68 words
A locking structure for doubly locking said short-circuit contact of the connector according to claim 1, wherein said base plate of said short-circuit contact comprises at least one locking protrusion, at least one locking recess is provided at the interior of said contact-support chamber of said one connector housing, and said short-circuit contact is locked to said contact-support chamber by engaging said locking protrusion with said locking recess.
Claim 4
Dependent Claim
41 words
A locking structure for doubly locking said short-circuit contact for the connector according to claim 1, wherein a portion of the short-circuit contact is locked at said base portion to the contact-support chamber of said one connector housing by force fit.
Claim 5
Dependent Claim
87 words
A locking structure for doubly locking said short-circuit contact for the connector according to claim 1 or 3, wherein said elastic contact pieces are formed by folding back a base plate in an arc shape and arranged in parallel with each other with a slit therebetween, a contact for short circuiting provided at an intermediate portion of each of said elastic contact pieces, an upraised portion provided at the free end of each elastic contact piece and a cover plate formed by bending said base plate thereof.
Claim 6
Dependent Claim
95 words
A locking structure for doubly locking said short-circuit contact for the connector according to claim 2, wherein said elastic contact pieces are formed by folding back a base plate in an arc shape and arranged in parallel with each other with a slit therebetween, a contact for short circuiting provided at an intermediate portion of each of said elastic contact pieces, and an upraised portion provided at the free end of each elastic contact piece, wherein said at least one locking protrusion is provided at a cover plate formed by bending said base plate thereof.
